Description

Electronic atomization device

Technical Field

The present disclosure relates to electronic devices, and particularly to an electronic atomizing device.

Background

An electronic atomization device is an electronic device which supplies power to an aerosol generator to operate the aerosol generator so as to heat an aerosol generating material to generate an atomization effect. Common electronic nebulization devices are for example electronic aerosol generating devices containing nicotine ingredients. The device is usually provided with a button on its surface, which is pressed to activate the aerosol generator (also called atomizer) for operation. Another starting scheme is that an airflow sensor is arranged in the electronic aerosol generating device, when a user needs to use the electronic aerosol generating device, the user inhales air slightly at an outlet of the aerosol, the airflow sensor senses the airflow, and then the power supply is switched on, so that the atomizer works.

However, for aerosol generating devices, which are typically designed to be small and the size of the buttons when provided is relatively small, it is not preferable for a user, who is typically male, to press the buttons because the buttons are too small for their fingers to feel.

Although the atomizer using the air flow sensor is free from a button for activating the atomizer, there is still a need for providing other electronic functions, such as a display/indication function, an atomization amount adjustment function, and the like, as electronic products, and thus there is still a need for providing a button or other control method.

Therefore, there is a need to design a design solution that can replace the button, provide a better user experience, and provide a better design solution if more functions can be integrated, under the conditions of a smaller size and a limited design space of the electronic atomization device.

Detailed Description

The invention relates to an electronic atomization device, which at least comprises an atomization cavity 40, an aerosol generator and a power supply 30 to realize the function of electronic atomization, as shown in figure 1. The aerosolizing chamber 40 has a cavity for receiving an aerosol-generating material, which may be any liquid that can be aerosolized, such as water, milk, essential oils, skin moisturizers or moisturizers, or therapeutic drugs, such as ambroxol for treating coughing in children, chymotrypsin, or nicotine-containing tobacco smoke for relieving craving or for cigarette substitution, and the like, without limitation. The aerosol generating material may also be a solid having one or more components that can be heated to vaporize and atomize, such as a tobacco paste (a material that is pasty and also has a nicotine component), a tobacco leaf, tobacco powder or tobacco particles, or other solid material that can be heated to form an aerosol or aerosol, without limitation.

The aerosol generator is electrically connected to the power source 30 to heat the aerosol generating material for vaporization and gasification to form aerosol. There are various ways to implement the heating and evaporation principle of the aerosol generator, such as resistance heat generation, electromagnetic induction heat generation, microwave heating, illumination heating, phase change reaction heat generation, or chemical reaction heat generation.

The resistance heat generation is a method of electrically heating a material by using a heat effect of a current passing through a resistor body. For example, the aerosol generator comprises a resistance wire with a certain resistance value and also comprises a liquid guide core. The aerosol generating material is guided to the resistance wire by the liquid guide core, and the resistance wire generates heat after being powered on, so that the aerosol generating material guided to the resistance wire can be heated until being evaporated. The liquid-permeable core may be heated by directly inserting the resistor into the aerosol-generating material, particularly when the aerosol-generating material is a solid.

The resistance wire is a spiral coil, can also be in a snake-shaped bending structure, or is in other shapes and structures such as net shape, strip shape, rod shape, sheet shape and the like. The resistance wire can be made of at least one of iron-chromium-aluminum alloy, nickel-chromium alloy, stainless steel and other metal materials.

The wick contacts and even immerses the aerosol-generating material while having one end or surface adjacent the resistance wire to direct the aerosol-generating material to the resistance wire, where "directing" may be either direct contact of the aerosol-generating material with the resistance wire or spaced adjacent the resistance wire. The liquid guiding core can be a fiber bundle, such as a cotton bundle or a glass fiber bundle, and can also be other columnar or block structures, such as oil guiding cotton, porous ceramic rings or ceramic blocks. The liquid guiding core can be positioned on the outer surfaces of the resistance wire, such as the upper surface, the lower surface, the left surface, the right surface and the like, and can also be positioned on the inner side of the resistance wire wholly or partially. For example, one end of a liquid guiding core made of a cotton wire bundle is sleeved with a resistance wire with a spiral coil structure or one end of the liquid guiding core is covered with a net-shaped resistance wire, and the other end of the liquid guiding core is immersed into the aerosol generating material; or a spiral coil is sleeved on the inner side wall or the outer side ring wall of the liquid guide core of the ceramic ring structure, and the like, and the invention is not limited in this document.

The electromagnetic induction heating is a heating method in which an electric current is generated inside a material to be heated by using an electromagnetic induction method, and the heating purpose is achieved by the energy of the eddy current. The aerosol generator based on the electromagnetic induction heat generation principle generally comprises an induction unit and a magnetic field generator, wherein the magnetic field generator generates an alternating magnetic field after being connected with a power supply in a certain mode, so that eddy current is generated inside the induction unit positioned in the magnetic field to generate heat, and the heat can heat an aerosol generating material. The sensing unit can be formed by dispersing a plurality of separated small elements in the aerosol generating material, or can be formed by sleeving a sensing coil and other structures or is close to the aerosol generating material or the atomization cavity.

Microwave heating and light heating are two other possible heating methods, one is a method of heating an object by using the energy characteristics of microwaves, and the other is a method of heating a liquid by irradiating the liquid with a light source having a higher energy density, such as an LED or an LD. Other possible heating methods include phase change reaction heat generation, which is a method of storing or releasing heat by using a phase change material to change between solid and liquid states, and chemical reaction heat generation. Chemical reaction heat generation is a method of heating an aerosol generating material by means of the exothermic heat of a chemical reaction, and is described in patents in the prior art, and is not described in detail herein.

In any of the above heating methods or other heating methods, the heating method of the present invention is not limited as long as the aerosol generator heats the aerosol-generating material and heats and vaporizes the aerosol-generating material, thereby changing the aerosol-generating material from a liquid phase to a gas phase.

The electronic atomization device of the invention also includes an inner shell 20, an outer shell 10 and a function realizing mechanism, the inner shell 20 accommodates the atomization cavity 40 and the aerosol generator, wherein the aerosol generator may be wholly or partially located in the atomization cavity 40, the atomization cavity 40 may be located in the inner shell 20 with an inner cavity, or the cavity wall of the atomization cavity 40 may form a part of the wall of the inner shell 20, for example, the bottom of the atomization cavity 40 is connected with a power supply shell or a power supply fixing frame equipped with a power supply 30, and the cavity wall of the atomization cavity 40 and the surface layer of the power supply shell or the power supply fixing frame together form the inner shell 20. The outer housing 10 is disposed on the outer periphery of the inner housing 20 and at least partially covers the surface of the inner housing 20. Or the outer wall of the atomization chamber 40 extends directly to the inner cavity for accommodating the power supply, i.e. the inner housing 20 is an integral structure with the atomization chamber 40.

In the present invention, the outer housing 10 can move relative to the inner housing 20, so that the relative position of the outer housing 10 moves from the first position to the second position, specifically, the outer housing 10 moves while the inner housing 20 is stationary, or the inner housing 20 moves while the outer housing 10 is stationary, or both of them can move but are not synchronized to have a relative displacement, for convenience of description, the inner housing 20 is described as a relative stationary state, but does not indicate that the inner housing 20 is absolutely stationary. The movement may be a movement of the whole or part of the outer housing 10 relative to the inner housing 10 along a specific movement track on the inner housing 20 or on the rest of the electronic atomizer, the displacement movement has a specific starting point, ending point and movement track, and the displacement does not cause the outer housing 10 to depart from the whole structure of the electronic atomizer, which makes the outer housing 10 of the present invention substantially different from the removable or openable box cover of the conventional electronic product.

In addition, the outer housing 10 herein should be distinguished from the push button in that the outer housing 10 is a ring surface or a structure similar to the ring surface that covers the inner housing 20, so as to be in a covered state; in addition, the outer housing 10 serves as an appearance structure of the whole electronic atomization device, and the covered area is more than 50% more than the inner housing 20, for example, the surface area of the inner housing is covered, or the outer housing constitutes the appearance characteristic of the main body of the device.

The invention is characterized in that the invention further comprises a function realizing mechanism, and the function of the electronic atomization device related to the function realizing mechanism is switched from the first function state to the second function state by moving the outer shell 10 relative to the inner shell 20 from the first position to the second position.

For example, the electronic atomization device includes an air passage for air to enter to cool the vaporized aerosol generating material and form aerosol, and then the aerosol escapes from the air passage, and after the electronic atomization device of the present invention moves relative to the inner housing 20 through the outer housing 10, the air passage is switched from a first functional state of being closed and isolated from the atmosphere to a second functional state of being opened and communicated with the atmosphere;

or, the function implementing mechanism of the electronic atomization device of the invention includes a switch, the switch is connected with the aerosol generator and the power supply 30, when the outer shell 10 of the device is located at the first position, the switch is disconnected, so that the electronic atomization device is in the first function state of circuit disconnection; when the outer shell 10 is located at a second position relative to the inner shell, the switch is turned on, so that the electronic atomization device is in a second functional state in which the circuit is turned on;

or, the function implementing mechanism of the electronic atomization device includes an indicator light, the on/off, flashing or light color change of the indicator light can indicate the operation state of the device to the user, when the outer shell of the device is located at the first position 10, the indicator light is turned off or the light thereof is shielded, so that the device is in the first function state of operation no-state indication; when the outer shell 10 relatively moves to the second position, the indicator light is turned on or exposed, so that the equipment is in a second functional state for indicating the running state; similarly, the function-realizing mechanism can also be a display screen, wherein the display screen is shielded or closed in the first position, and the display screen is opened and related information is displayed in the second position.

Therefore, the electronic atomization device, which is generally an electronic device operable by one hand, can easily move the outer shell from the first position to the second position relative to the inner shell through the hand operation, for example, the actions of turning, lightly pushing, pulling and the like can be realized, so that the playability of the device is improved; while operating, it can realize certain function switching, and the function switching can further increase the necessity of playing and reduce the operation steps.

The electronic atomizing device of the present invention will be explained below by way of specific examples and the accompanying drawings, wherein like elements in different embodiments are referred to by the associated like element numbers. It is to be understood that each of the embodiments and non-illustrated embodiments, together with the features, which may be used to advantage in connection with other embodiments, are set forth more fully above and, to the extent not expressly stated or contradicted by context, all of the above is applicable to the particular embodiments described below and is not intended to be construed as necessarily requiring the presence of all such features and aspects independently of the embodiment. Also, in the following embodiments, many details are described in order to enable the present application to be better understood. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods, etc. in various instances, and are not to be construed as necessarily limiting the present embodiments.

The first embodiment is as follows:

fig. 2a to 2c are schematic structural diagrams of an electronic atomization device according to a first embodiment of the invention. As shown in fig. 2 a-2 c, the electronic atomizer device includes a housing, an atomizing chamber 40, an aerosol generator, and a power source 30. The atomizing chamber 40 has a chamber for containing an aerosol generating material, the aerosol generating material is a liquid containing nicotine or other components to be atomized, and the aerosol generator is connected to the power supply 30 and then operated to heat the aerosol generating material, so that the aerosol generating material is vaporized and then mixed with air to be atomized to form aerosol. After the aerosol escapes from the shell, the aerosol can be inhaled by the mouth or the nose of a user, so that the aerosol is sucked by a human body and has certain functions of an airway, such as smoking addiction relief, asthma or epilepsy treatment, cough relief and the like.

Wherein the housing comprises an inner housing 20 and an outer housing 10, the aerosol generator is located inside the nebulizing chamber 40 and not shown in this embodiment, the nebulizing chamber 40 and the power source 30 are located inside the inner housing 20 or the outer wall is an integral structure with the inner housing and not shown. An air passage is provided in the atomizing chamber 40, which is a function realizing mechanism in this embodiment. An air passageway is located in the inner housing 20 and through the aerosolizing chamber 40, including at least an inlet and an outlet and an air flow path therebetween. Of course, the outlet, inlet and air flow passages herein are not necessarily of a particular configuration, as long as the aerosolizing chamber has a location or region thereon that allows air to enter and contact the aerosol-generating material, flow and escape therefrom, e.g., inside and outside the aerosolizing chamber solely by the presence and infiltration of air itself, and the aerosolizing chamber is also considered to have an air passageway thereon as described herein, with the air passageway having an inlet and an outlet. When the atomizer chamber 40 is located within the inner housing 20, the corresponding inner housing has inlets and outlets for allowing air to enter and exit the atomizer chamber. The position and form of the particles are not limited herein.

As shown in fig. 2a, in this embodiment, the inner housing 20 is cylindrical, the outer housing 10 is also similarly cylindrical, and includes a cylindrical side surface 17 and end portions 16 at two ends, which integrally cover the entire inner housing 20, and the outer housing 10 includes a first portion 12 and a second portion 14, the first portion 12 and the second portion 14 are spliced together in an axial direction L of the housing, and the spliced surface 13 is a plane or a curved surface forming an included angle with the axial direction L, where the included angle is between 0 and 90 degrees, that is, the spliced surface 13 is disposed obliquely with respect to the axial direction L. The outer housing 10, in particular the first section 12 of the outer housing 10, is now in a first position relative to the inner housing 20.

And, a space is provided between the inner wall of the outer housing 10 and the outer wall of the inner housing 20, the space being at least greater than 0.3mm, so that air can flow in the space, the air communicating with the air passage on the inner housing 20. The end of the first part 12 is provided with a vent hole 11, when the first part 12 is located at the first position, the vent hole 11 is blocked by a protruding structure 22 arranged at the corresponding end of the inner housing 20, and simultaneously the first part 12 and the second part 14 are spliced oppositely, so that the whole outer housing 10 is matched with the end of the inner housing 20 to form a closed housing, the atmosphere outside the outer housing 10 is blocked from the atmosphere inside the outer housing, the air passage cannot be communicated with the outside atmosphere, and therefore, when the first part 12 is located at the first position, the electronic atomization device is in a first functional state that the air passage is closed.

Since the inner case 20 and the outer case 10 are cylindrical and the split surfaces 13 are inclined, the split surfaces 13 are approximately inclined elliptical surfaces. In this embodiment, as shown in fig. 2b and 2c, the second part 14 and the inner housing 20 are fixed relatively statically and integrally, and the first part 12 can perform relative displacement with respect to the second part 14, that is, with respect to the inner housing 20, in this embodiment, it rotates around a shaft while the axial displacement finally generates a spiral motion. The spiral shape here is not necessarily a spiral shape in a geometrically strict sense, i.e. a case where the circular motion has a uniform linear motion at the same time. In the present invention, a spiral shape is to be understood as long as the component has an axial displacement while rotating. When the first portion 12 is rotated to a predetermined second position, a separation region is formed between the mating surfaces 18 and 19 of the first and

second portions

12 and 14, which forms an air inlet 21 that communicates with the air inside the outer casing 10 to form an air inlet passage.

Meanwhile, because the first part 12 is axially displaced relative to the second part 14, the vent hole 11 at the end of the first part 12 is no longer blocked and becomes the air outlet 15 because of moving up away from the end of the inner shell 20, so that the atmosphere outside the outer shell 10 is communicated with the atmosphere inside the outer shell 10 through the air outlet 15 and becomes an air outlet channel. At this point, the first portion 12 is moved to the second position and the electronic atomizer device is in the second functional state with the airway open.

Thus, in this embodiment, when the first portion 12 is in the first position relative to the inner housing 20, the outer housing is a closed space, and both the inlet and outlet of the internal nebulizing air channel are closed; when moving to the second position by relative displacement, the air inlet 21 and the air outlet 15 are formed on the outer casing 10, and communicate with the inlet and the outlet of the internal air passage through the gap between the inner casing 20 and the outer casing 10, that is, the air passage is opened. Obviously, the positions of the air inlet 21 and the air outlet 15 are interchangeable.

The inlet and the outlet of the air passage are closed before action, and are opened until the user performs hand action when in use, which can bring great beneficial effect in practical application. Since the air passage is an indispensable structure for the atomizing device for heating evaporation, the introduction of air through the air passage can rapidly cool the vapor downstream of the aerosol generator, causing it to condense the nominal aerosol. However, whether liquid or gas exists, as long as there is a physical gap, the problems of liquid leakage and air leakage may occur, and the user feels very bad for inhaling the liquid or liquid droplets and should avoid them as much as possible; in addition, in the transportation process of the equipment, due to the existence of the air passage, when the air pressure in the atomizing cavity connected with the air passage is inconsistent with the ambient air pressure, for example, in the air transportation process, the liquid leakage condition is easily caused, and the use of the product is influenced. In the invention, the air channel is completely closed and isolated from the atmosphere before use, so that the situations are completely avoided.

The present invention therefore protects an electronic atomising device which forms part of the first part 12 of the outer housing 10, in a first position in which the outer housing 10 forms a closed space, or in which a part of the area of the inner housing 20 forms a closed space, and in a second position in which the air inlet 21 and the air outlet 15 are formed so that the internal air passage is open to the atmosphere.

In this embodiment, the function-realizing mechanism includes, in addition to the air passage, a transmission mechanism that guides the first portion 12 to move from the first position to the second position. Through the limit of the transmission mechanism, the first part 12 always moves along the split surface 19 of the second part 14, that is, at least one point on the first part 12 is kept in contact with the split surface 19 of the second part 14, so that the compactness of the structure and the hand feeling of a user are kept. Such a transmission mechanism can be realized in a structural design, for example, by means of spring pressing, sliding groove and sliding rail limiting, flat key fitting, a gear or a tug or a link mechanism, and the like, which is not limited herein.

In addition, in this embodiment, the joining surface 13 may be a plane, that is, the joining surface 13 has a projection surface such that the projection of the projection surface on the projection surface is a straight line. The movement of the first section 12 relative to the inner housing 20 is now a standard helical shape. When the projection of one of the split surfaces 13 on the projection surface is a curved surface, such a split surface is actually a curved surface, and preferably the split surface is a curved surface having a symmetry plane, which may be the projection surface of the split surface. In which case the relative motion is a generalized spiral.

In the cylindrical shell structure of the present embodiment, the projection of the split surface 13 to the symmetry plane is preferably a curve, and the curve is a rotational symmetry curve, and the inclination angle of the end curves at the two ends of the curve relative to the axial direction is greater than or less than the inclination angle of the middle curve relative to the axial direction, i.e. the inclination degrees of the two ends of the curve relative to the middle part are different. With such a structure, the axial displacement of the first part 12 when the first part is separated along the axial direction is relatively reduced, i.e. the action of operation when a user uses the device is not too large, which is beneficial to the miniaturization of the volume and is convenient to operate. The user is holding the second part, and thumb and forefinger are pinched the first part simultaneously, rotate to its application of force, and the finger can not be pushed up too far and lead to feeling unnatural, and user experience is good. For similar reasons, it is preferred that the angle of inclination of the split surfaces with respect to the axial direction is greater than 45 degrees and less than 90 degrees, for example 60 degrees. In addition, the change of curves at two ends is also beneficial to designing the outline shape of the separation area enclosed after displacement.

The movement of the first portion 12 from the first position to the second position may be performed not only to switch the functional state of opening and closing the air passage but also to switch other functional states. For example, movement of the first portion 12 relative to the inner housing 20 may be used as an action judgment to activate the present electronic atomizer device.

Specifically, in another embodiment of the present invention, the electronic atomization device has the structure as in the above embodiments, such as the first portion 12 and the second portion 14, the inner housing 20, the aerosol generator and the atomization chamber 40, and the structural features of the above embodiments can be fully incorporated into this embodiment, which will not be described in detail below.

Unlike the structure of the above-described embodiment, the function implementing mechanism in this embodiment is a switch, and the switch is disposed between the power supply 30 and the aerosol generator. When the first part 12 is located at a first position relative to the second part 14, the switch is open, and the aerosol generator is in a first functional state in which the circuit is open and the aerosol generator cannot work; when the first part 12 is moved to the second position, the switch is switched on, so that the aerosol generator starts to operate or enters a second functional state to be operated.

There are many switches for realizing the switching of the functional state, such as a light touch switch, an electromagnetic switch, a photoelectric switch, a delay switch, a proximity inductive switch, etc., and the corresponding transmission mechanism is designed in combination with the kind of the switch, so as to realize the switching function of the switch, for example, in one embodiment, a light touch switch is adopted, a contact is arranged on the inner shell 20 or the outer shell 10, and the switch is not contacted with the contact in the first position, so that the switch is disconnected; in the second position the switch is moved into contact with the contacts so that the switch is closed and the aerosol generator is operated. Alternatively still, in another embodiment a photoelectric switch is used, in a first position the first part 12 blocks the photoelectric switch, resulting in failure to receive light, the photoelectric switch is off, in a second position the first part 12 is no longer blocked, the photoelectric switch is on, the aerosol generator starts to operate or enters a standby state, and so on. This is not described in detail herein.

Of course, in the present embodiment, it is not necessary to simultaneously switch the functional states of opening and closing the air passage, and therefore the end portion of the first portion does not necessarily need the ventilation hole 11 in the present embodiment. Meanwhile, when the first part 12 is located at the first position, it is not necessary to form a closed space with the second part 14, or the first part 12 is not necessarily required to be seamlessly spliced with the second part 14; likewise, the first portion 12 does not necessarily have to be separated from the second portion 14 when moved to the second position, but may be moved to remain in a seamless or partially overlapping nested configuration with the second portion 14, or other configurations.

Certainly, when the outer shell structure shown in fig. 2a to 2c is adopted, the function switching of whether the air passage is opened and closed and the aerosol generator works can be synchronously realized, the structure is simple, the operation steps of a user can be obviously reduced, the problem of liquid leakage caused by the fact that the air passage is normally opened is also avoided, and the air-conditioning system has very good user experience and practical effect.

Therefore, the present invention also protects an electronic atomization device, when the outer shell 10 is in a first position relative to the inner shell 20, the outer shell 10 forms a closed space integrally or in cooperation with the inner shell 20, so that air inside the electronic atomization device is isolated from the atmosphere outside the outer shell 10, and the aerosol generator is powered off; when the outer housing 10 moves to the second position relative to the inner housing 20, an air inlet channel and an air outlet channel are formed on the outer housing 10 or between the outer housing 10 and the inner housing 20, and are communicated with the air channel on the inner housing 20, and at this time, the aerosol generator starts to work or enters a standby working state.

On the other hand, in order to avoid misoperation, when the outer shell 10 of the electronic atomization device moves from the first position to the second position, the device is switched from the first function state of power failure of the aerosol generator to the second function state of power connection; when the outer housing 10 is moved from the second position to the first position, the aerosol generator will switch to the first, de-energized functional state, i.e. when the outer housing 10 is in a position between the first position and the second position and in the first position relative to the inner housing 20, the device is in the first, de-energized functional state. The function realizing mechanism, that is, the switch of the embodiment has the following functions: when the relative movement of the outer housing 10 is from the position between the first position and the second position as the starting point to the second position, the present electronic atomization device still maintains the first functional state of power-off. That is, the electronic atomization device switches from the first functional state to the second functional state if and only if the movement of the outer housing is from the first position to the second position.

The advantage of this arrangement is that the user does not push the outer housing back into the first position after use, and there may be situations where inadvertent closing may occur, where it is determined whether the user has a clear need to re-activate the device despite the outer housing leaving the second position and the device switching to a power-off inoperative state, and it is necessary to force the user to push the outer housing back into the first position again to confirm the necessity of use in order to avoid waste of aerosol generating material and loss of the device under abnormal use.

There are many ways to implement the above functions, for example, the function implementing mechanism of the present embodiment includes a switch, a first contact and a second contact, the switch is located on the inner housing, the two contacts are located on the outer housing 10, or vice versa. The first contact and the second contact are located on a relative movement track of the switch with the movement of the outer housing 10 relative to the inner housing 20.

When the outer housing 10, such as the first portion 12, is in the first position, it is in contact with or close to the first contact, at which point the circuit is de-energized; then, when the outer housing 10 moves to the second position, the circuit is powered on and the aerosol generator is operated or in standby mode through the first contact and through or in contact with the second contact to reach the second position. When the outer casing 10 returns to the first position from the second position, it is determined whether the outer casing passes through the first contact again or contacts the first contact again, that is, whether the outer casing returns to the first position is determined. If the device does not return to the first position and move directly from the intermediate position to the second position, the device may determine that the starting position is not the first position, thereby maintaining the first functional state rather than switching to the second functional state.

The judgment of the first position and the second position can be judged by means of the difference between the first contact and the second contact, the first contact and the second contact can be distinguished by correspondingly outputting different electric signals every time the two contacts pass or contact once, or by means of a nand gate algorithm or a third switch which needs to be triggered by the combined action of the two, and corresponding technical schemes can be found in the prior art, and are not repeated herein.

For example, a possible embodiment is that the electronic atomization device of the invention further includes a microprocessor, which is connected to the switch, the switch sends out a first electrical signal through the first contact and sends out a second electrical signal through the second contact, the microprocessor receives the first and second electrical signals, stores and judges the first and second electrical signals, and when the first electrical signal is received, the microprocessor controls the switch to be turned off, and the device is in a first functional state; when the second electrical signal is received, the microprocessor judges that the electrical signal received before the electrical signal is the second electrical signal, and the equipment still keeps the first functional state. Such a design may encourage the user to move the device back to the first position sufficiently each time to trigger the first electrical signal. Further optionally, when the second electrical signal is received, and the electrical signal received before the electrical signal is detected is the first electrical signal, and the time interval between the receipt of the first electrical signal and the receipt of the second electrical signal is within the preset time, the device enters the second functional state, and the first functional state is still maintained after the time interval exceeds the preset time.

In addition, whether the outer casing 10 is moved from the first position to the second position instead of the position between the first position and the second position is not necessarily determined by determining that the outer casing is located at the first and second positions, but may be determined by directly detecting the current specific position by using a position detecting component, for example, light sensing, infrared, scanning, etc. can be used to detect and determine the current position of the outer casing, and then further determine the relationship between the outer casing and the first and second positions.

On the other hand, in order to prevent the excessive amount of the aerosol generating material during each atomization, especially in the case that the aerosol generating material is nicotine or the pharmaceutical composition needs to be strictly controlled, the function implementing mechanism of the electronic atomization device of the invention further comprises a time detecting element, the time detecting element starts to count time after the outer shell moves to the second position, so that the device starts to atomize, and after the atomization time reaches a preset value, the device stops the atomization work, namely returns to the first function state. For example in a nicotine containing electronic atomising device the outer housing is moved to the second position and the device will automatically return to the first functional state 10 seconds after entering the second functional state. At this time, the device may stop the atomization, and may further control the outer housing to automatically reset to the first position.

Further, the time detecting element of the present invention may be used as other time detection, for example, it detects a time interval between a time point of the present relative movement of the outer case to the second position and a time point of the last relative movement of the outer case to the second position. If the time interval is larger than the preset value, the equipment is switched to the second function state when the equipment moves to the second position, and if not, the first function state is still kept. This is because nicotine or a pharmaceutical aerosol generating material or other aerosol generating material intended to enter the human body has an upper limit to the amount that can be absorbed in the human body, and a certain metabolic resolution time is required after each inhalation, so that continuous, uninterrupted use, especially for a short period of time, should be avoided as much as possible, and a time interval is set to help solve this problem. For example, for an electronic cigarette as the electronic atomization device, the preferred time interval is up to 10 seconds or more.

Further, the time detecting element of the present invention may also be used to calculate the accumulated operating time, that is, the outer shell returns to the first position after moving from the first position to the second position as a period, and calculate the accumulated time of each period, where a specific calculation point may be that the time between the start point and the end point of the period is the valid time of one period, the time of the device staying at the second position is the valid time, or the time of the device in the second operating state during the time of the device staying at the second position is the valid time, and the like. When the time detection element detects that the accumulated time is less than a preset value, the outer shell moves from the first position to the second position, the equipment is switched to the second functional state, otherwise, the equipment still maintains the first functional state even if the outer shell moves to the second position.

The advantage of such a design is that the amount of aerosol generating material is constant, and usually after the aerosol generating material has evaporated to a certain amount, the content of active ingredient is reduced or the total residual content is too low, which may result in the atomized aerosol or aerosol not reaching the desired effect, or even may cause negative effect due to dry burning, etc., so that the user may be reminded to replace the atomizing chamber or update/add the aerosol generating material as soon as possible by using the above scheme.

The function-realizing mechanism of the present invention may further include a reset assembly that drives the outer housing to reset to the first position when the outer housing is about to move to the first position from the second position, or when the electronic atomizer is in the first functional state but the outer housing is not in the first position relative to the inner housing. The reset component can be realized by adopting elastic element abutting, electromagnetic adsorption and the like, and the detailed description is omitted.

In the above embodiment, the first functional state is that the electronic atomization device is switched off, and the aerosol generator does not work, and the second functional state is that the electronic atomization device is switched on, and the aerosol generator works to perform heating atomization; or the first functional state is a state that the electronic atomization device circuit is connected with electricity but the aerosol generator does not work, namely, the aerosol generator is ready to work, and the second functional state is that the electronic atomization device circuit is connected and the aerosol generator is heated and atomized; or, the first functional state may be that the electronic atomization device circuit is disconnected, the aerosol generator cannot operate, the second functional state is that the electronic atomization device circuit is connected with electricity, but the aerosol generator does not operate, and further triggering, such as mouth inhalation or nasal inhalation action, fingerprint or face recognition or other identity recognition, is required to start heating atomization, and at this time, the first functional state is the state to be operated.

In another embodiment, continuing to use the structure diagrams shown in fig. 2a to 2c, in this embodiment, there may be or may not be function switching of opening and closing the air channel, or there may be function switching of opening and closing the switch, and in this embodiment, function switching of whether to display the working state of the device may be realized by moving the outer housing from the first position to the second position relative to the inner housing.

Specifically, the function implementing mechanism of the embodiment includes a display element for indicating an operating state of the electronic atomization device, when the outer housing is located at a first position relative to the inner housing, an effective display area of the display element is shielded, and the electronic atomization device is in a first functional state without displaying the operating state; when the outer shell is in a second position relative to the inner shell, the effective display area of the display element is exposed, and the electronic atomization device is in a second functional state of the working state of the display device.

For example, the display element is a LOGO region located on the corresponding surface of the inner shell at the splicing surface of the first part and the second part, i.e. on the separation region formed by the axial separation of the first part relative to the second part, and the LOGO may be a LOGO or a pattern, etc., and the LOGO region has a boundary. When the first part is at an initial first position, the first part is spliced with the second part to shield the identification area, and the equipment is in a first functional state of not displaying the identification area; when the outer shell moves to a second position relative to the inner shell, the boundary of the identification area is exposed to indicate that the second position is reached, and the electronic atomization device is in a second functional state for displaying the identification area.

Or the display element is a display screen element, and the display screen element acquires parameters related to the working state of the electronic atomization device through an electric element, such as the temperature of the aerosol generator, the residual quantity of aerosol generating materials, the number of residual ports, the electric quantity of the power supply and the like, and displays the information on a screen. For example, the display screen element is located at the outer surface of the inner housing corresponding to the splicing face of the first and second portions, i.e. on the splitting area. When the first part of the outer shell is positioned at the first position, the first part and the second part are spliced to shield the display screen element; the first part is moved to a second position, which is separated from the second part, and the display screen element is exposed, so that the operating state of the device can be displayed.

Alternatively, the display element is a light element, and the light emitted by the light element is turned on, turned off, flickered, dimmed or changed in color according to a change in the operating state of the electronic atomizing device, for example, the light is bright when the aerosol generator is operated, and is not lit when the aerosol generator is not operated, and flickers when the remaining amount of aerosol-generating material is small. In the first functional state, the light element may be directly shielded or exposed so as not to display the indicated device working state, or the light emitted by the light element may be shielded or exposed, especially the light is guided out through a certain light guide element. I.e. the active display area of the light element is at least part of the light it emits. For example, the light element may be located below the upper end face of the inner housing, and the light may be exposed through the vent hole at the end of the first portion by lateral reflection. Therefore, when the first part is located at the second position after being axially separated relative to the second part, the vent hole is not blocked any more, a fall area is formed between the end part of the vent hole and the end part of the inner shell, and the light of the light element can be exposed on the fall area at the moment so as to provide the corresponding working state of the display device.

These functions are not necessarily implemented in different embodiments respectively, and may be implemented by combining three or two, and by using a structural scheme, for example, the aforementioned first part is separately displaced relative to the second part, i.e. the air inlet and the air outlet can be opened synchronously, while the aerosol generator is operated by triggering the switch, and the separated area enclosed by the displacement can be used as a display, for example, a LOGO or a light is provided. Therefore, the function is not limited herein.

In the above embodiments, the housing is a cylindrical housing as an example, and those skilled in the art can easily think that the housing is implemented by using other shapes of structures, such as a triangular prism or a quadrangular prism, but the actual motion trajectory inside the housing is still moved spirally by rotating the first part similarly to the present embodiment, and still fall within the protection scope of the present invention.

Example two:

fig. 3a to 3b show schematic structural diagrams of an electronic atomizing device according to a second embodiment, and similar to the first embodiment, the housing of the present embodiment also includes an inner housing 20 and an outer housing 10, and the outer housing includes a first portion 12 and a second portion 14, and other structural and functional features not described below can refer to the first embodiment and the foregoing description, and are not repeated herein.

In this embodiment, the whole device is a rectangular cylinder, the first part 12 and the second part 14 of the outer shell 10 are axially spliced, and the splicing surface 13 is a curved surface. Unlike the above-described embodiments, the first portion 12 of the present invention moves linearly in the axial direction when moving from the first position to the second position relative to the second portion 14 and the inner housing 20, rather than pivoting or screwing, and moves linearly in the axial direction relative to the second portion 14 directly to separate from the second portion 14, thereby forming a separation region.

The relative movement of the inner housing 10 and the outer housing 20 can be achieved by means of certain transmission mechanisms, such as a key and keyway mechanism, a sliding track and sliding groove mechanism, or can be achieved without transmission mechanisms and only by means of certain limiting structures, such as longitudinal limiting constraints formed by the edges of the rectangular body and the combined action of distance limiting points arranged inside the housing, etc., which are not further described herein.

Similar to the first embodiment, the end of the first section 12 is provided with a vent hole 11, which vent hole 11 is closed by a raised formation 22 on the inner housing before the relative movement, and the end of the first section 12 moves up away from the raised formation 22 after the relative movement, so that the vent hole 11 communicates with the atmosphere inside and outside the outer housing 10 to become the air outlet 15.

Similar to the first embodiment, when the first part 12 is in the first position, it forms a closed space with the second part 14 before relative movement, the vent hole 11 is blocked by the inner shell, so that the air passage of the aerosol generator is blocked from the atmosphere, and the electronic atomization device is in the first functional state that the air passage is closed; when moving to the second position, the separation region between the first part 12 and the second part 14 forms the air inlet 21, the hole-shaped region at the end of the first part forms the air outlet 15, and the air inlet 21 and the air outlet 15 are in communication with the air passage, and the electronic atomizing device is in the second functional state in which the bridge is open.

In this embodiment, the first embodiment and other possible embodiments, the hole-shaped area is disposed at one end of the first portion, and obviously, the air inlet and the air outlet may be replaced, for example, the separation area between the first portion and the second portion is used for air outlet, and the positions of the air inlet and the air outlet of the air passage are also replaced correspondingly.

Similar to the first embodiment, the separation area between the first portion and the second portion, and the fall area after the first portion is displaced relative to the inner housing can also be used as other functions, such as a display function for displaying lights, a display screen, a logo, etc., or can also be used as a trigger for turning on/off a switch, or other function controls based on displacement detection, which are described with reference to the first embodiment.

Example three:

fig. 4a to 4b are schematic structural diagrams of an electronic atomization device according to a third embodiment of the present invention, and unlike the above embodiments, the housing according to the present embodiment includes an inner housing 20 and an outer housing 10, where the outer housing 10 is an integral structure.

In this embodiment, the outer housing 10 is tubular and is fitted over the outer peripheral surface of the inner housing 20 so as to partially cover the inner housing 20, and the atomizing chamber and the aerosol generator are located in the inner housing, or the atomizing chamber and the inner housing are integrated so that the wall surface of the atomizing chamber is a part of the inner housing 20.

Fig. 3a is a state in which the outer case of the present embodiment is in the first position. Wherein one end of the outer shell 10 is provided with a chamfer 110, and the chamfer 110 forms a gap at the end of the outer shell 10, and the gap forms an air outlet. The other end of the outer case 10 is opened and the bottom of the inner case 20 is exposed therefrom. An air passage is provided in the inner housing 20, the air passage having an inlet and an outlet 210. In this first position, the inlet and outlet 210 of the air passage are both located within the envelope of the outer housing 10 and isolated from the atmosphere, and the electronic atomising device is in a first functional state in which the air passage is closed.

When the device is required to start up, the outer housing 10 is rotated relative to the inner housing 20, for example, the bottom of the inner housing 20 exposed to the outer housing 10 is pinched to be rotated as a hand-held portion, and then twisted to a second position, as shown in fig. 3b, one end of the inner housing has a slope, and the slope is rotated to be flush with the chamfered surface 110 of the outer housing, and the outlet 210 on the slope of the inner housing 20 is exposed. The aerosol in the airway can now escape through the outlet and be used by the user.

The lower end of the outer casing 10 is also a chamfered surface 111, the inclined angle between the chamfered surface 111 and the axial direction is 0 to 90 degrees, and the notch formed on the outer casing 10 by the chamfered surface 111 forms an air inlet. The inlet of the air passage on the inner housing 20 is located in the space enclosed by the rotation trajectory of the chamfered surface 111, the inlet is located in the envelope of the outer housing 10 and hidden from the atmosphere before rotation, and the inlet is exposed outside the contour space of the outer housing 10 to align with the air inlet and communicate with the atmosphere after rotation. I.e. in the second position, the electronic vaping device is in a second functional state in which the air passage is open.

Therefore, by the above structure and the movement of the outer housing relative to the inner housing 20 from the first position to the second position, the inlet and outlet 210 of the air passage can be aligned with or separated from the air inlet and the air outlet of the outer housing 10, respectively, so as to open and close the air passage, i.e., to switch the electronic atomization device from the first functional state to the second functional state.

In the present embodiment, the air outlet is the chamfer 110, but obviously for the purpose of exposing a new area by rotation of the present invention, the lower end of the outer housing is not necessarily the chamfer 111, as long as there is a distance from a partial area to a cross section perpendicular to the axial direction in each area of the end surface of the lower end not equal to the distance from other areas of the end surface of the lower end to the cross section, and the air passage inlet and/or outlet on the inner housing 20 is rotated out of the coating area of the outer housing 10 to be exposed after the outer housing is moved to the second position, so that the object of the present invention can be achieved.

Alternatively, the outer housing 10 may be provided with a hole-shaped air inlet and an air outlet, the inner housing 20 is also provided with an inlet and an outlet of the air passage, and when the outer housing is located at a first position relative to the inner housing, both the air inlet and the air outlet are misaligned with the inlet and the outlet, so that the air passage is blocked from the air outside the outer housing, and the electronic atomization device is in a first functional state in which the air passage is closed; and when the shell body rotates to the second position, the air inlet and the air outlet are respectively aligned with the inlet and the outlet of the air passage, so that the air passage is communicated with the external atmosphere, and the electronic atomization device is in a second functional state in which the air passage is opened.

In order to secure the air-tightness, it is preferable that the interval between the inner surface of the outer case 10 and the outer surface of the inner case 20 is less than 0.5mm to reduce the entrance of air. Alternatively, the outer casing 10 may be made of plastic, rubber, or other elastic material, and is directly surface-contacted and sleeved on the inner casing 20, so as to ensure the requirement of air tightness. Alternatively, sealing members are arranged between the air inlet and the inlet and between the air outlet and the outlet so as to realize the sealing of the air channel.

Similarly, other features, such as structures and functions, not described in this embodiment can refer to all the corresponding descriptions above, for example, the exposed bottom area of the inner housing and the exposed bottom area of the outer surface can also be used as a new area generated by relative displacement, and can also be used as a display function, a switch start or other control related detection function, and the like.

The above embodiments further illustrate the structure, function and advantageous effects of the electronic atomizer according to the present invention, and those skilled in the art can easily make combinations, substitutions and modifications based on the above structures and/or functions without departing from the spirit of the present invention.

In summary, in the present invention:

in one aspect, the electronic atomizer device of the present invention switches from a first functional state to a second functional state by moving the outer housing relative to the inner housing from a first position to a second position; the function here may be any function related to the operation of the electronic atomization device, such as a display, an air passage, a switch, etc., as long as the function is switched by the position shift of the inner and outer housings, which is within the protection scope of the present invention.

In another aspect, the invention also includes an electronic atomizing device having an outer housing in a first position prior to use, wherein the outer housing is adapted to cooperate with the inner housing to isolate ambient atmosphere from the inner housing atmosphere such that an enclosed space is formed within the outer housing, the device being in a first functional state in which the air passageway is closed; when the air duct is needed to be used, the outer shell moves to the second position, and an air inlet channel and an air outlet channel communicated with the air duct atmosphere are formed on the outer shell and/or the inner shell at the moment, so that the oil leakage condition can be effectively avoided, and the user experience is improved;

on the other hand, the invention also protects the electronic atomization device, when the outer shell is at the first position, the electronic atomization device is in the first functional state of not carrying out atomization work, and the electronic atomization device can be in a power-off state or a power-on state; when the outer housing is moved into a second position relative to the inner housing, the device enters a second functional state of the atomizing operation or of the operation to be atomized.

Further, when the electronic atomization device switches the function state of atomization work, the electronic atomization device further comprises a step of judging whether a displacement starting point of the outer shell when moving to the second position is the first position, if so, the device is switched to the second function state, and if not, the device keeps the first function state.

Further, when the outer shell moves from the first position to the second position to enable the electronic atomization device to enter a second functional state, and the second functional state is a state in which the aerosol generator performs atomization work, the electronic atomization device further comprises a time detection element for detecting the duration time of the second functional state, or detecting the stay time of the outer shell from reaching the second position, and stopping atomization work when the time reaches a preset value.

On the other hand, the invention also protects the electronic atomization device, when the outer shell is positioned at the first position, the whole body or the inner shell is matched to form a closed space, so that the air inside the electronic atomization device is isolated from the atmosphere outside the outer shell, and the aerosol generator does not work at the moment, which is a first functional state of the device; when the outer shell moves to a second position relative to the inner shell, an air inlet channel and an air outlet channel are formed on the outer shell or between the outer shell and the inner shell, the air inlet channel and the air outlet channel enable an air channel of the inner shell to be communicated with the atmosphere, and the aerosol generator starts to work or enters a to-be-worked state, which is a second functional state of the device; by adopting the scheme, the patient can open the air passage by only one action and start the aerosol generator, so that the patient can be facilitated to the maximum extent, and the use operation is reduced.

Further, it is preferred that the electronic atomizer of the present invention is a snuffing atomizer, i.e. the area where the aerosol escapes from the housing in the previous embodiments and is directly snuffing for the user is a snuffing portion, i.e. the outlet or air outlet in the previous text, near which the nasal cavity of the user draws in to suck the aerosol. As snuff products, there is a need to provide new solutions to the problem of the design of operating parameters and characteristics, as opposed to the oral inhalation.

First, the aerosol escapes to the snuff where the temperature of the aerosol is below 55 degrees celsius. This temperature can be measured by placing a temperature sensor in the nasal inhalation portion without affecting normal aspiration. Because the nasal cavity is much less temperature tolerant than the oral cavity, the working temperature at the nasal inhalation portion of the present invention is less than 55 degrees celsius, and preferably less than 48 degrees celsius. In the present invention, the temperature of the snuff portion can be limited to a certain range by normal suction during use, since the suction takes away a portion of the heat. Thus, the temperature of the snuff portion herein is measured in the puff state, and the measurement is made by placing a temperature sensor at the snuff portion in the standard mode (ISO mode) of the Smoking Cycle Simulator (SCS). However, in practical designs, it is preferable to control the temperature of the aerosol generator or the temperature of the nasal inhalation portion, for example, the aerosol generator is not allowed to operate for a long time without pumping to cause heat accumulation and the temperature is too high, so that certain measures, such as temperature monitoring and intelligent power adjustment, are taken, or the aerosol generator is directly stopped every certain time until the next start. Therefore, it is preferred that the temperature of the snuff portion of the device never exceed 55 degrees celsius, whether under normal suction conditions or not. Then, in this case, the measurement means that after the device is started, the temperature sensor is directly placed in the nasal inhalation part to detect the temperature, and the temperature should not exceed 55 ℃ all the time. This is distinguished for an oral atomising device, since the temperature at the mouthpiece of the oral device is at least above this range when aspirating or when not aspirating, since the tolerance of the oral inhalation to temperature is relatively high.

In addition, the temperature of the device can reach more than 200 ℃ generally due to the heating evaporation principle, then the device is condensed in a very short time and distance and is mixed with air to form aerosol, and the aerosol finally escapes to the snuffing part, so that a certain temperature can be still kept, especially when the device is held by hands, the temperature reduction path is shorter due to the small volume of the device, the temperature reduction degree is limited, and the lower limit of the temperature is 25-30 ℃.

In order to realize miniaturization, the distance from the heating surface of the aerosol generator to the surface of the orifice of the opening of the snuffing part is 0.5-3 cm, and preferably 0.8-2.0 cm. The temperature during escaping cannot be too low, and the escaping temperatures are higher than 30 ℃ through detection by adjusting different distances by the inventor. The heating surface here refers to a surface of the aerosol generator that vaporizes the medical liquid, for example, a surface on which the heating wire is located, and there are a plurality of surfaces, and the surface closest to the inhaling portion is a plurality of surfaces, and the distance from the surface to the inhaling portion is calculated by taking the closest point.

In addition, because the snuff portion is designed for the nasal cavity, which has a much smaller nostril size than the mouth, the size of the opening in the snuff portion for aerosol to escape should be as small as possible, preferably less than 20mm in radial dimension, to ensure that the aerosol does not escape excessively. In some embodiments, it is preferred that the snuff portion employ a circular or oval or other similarly shaped hole, preferably less than 12mm in diameter.

The snuff portion is a portion for delivering the aerosol to the nasal cavity, and may be disposed at an end portion of the casing, on an outer surface of the casing, for example, in a middle portion of the outer surface of the columnar casing, on end surfaces of both ends, or in other positions. The snuff portion is typically porous to allow the aerosol to escape, and may be in the form of a cavity that contains a quantity of the aerosol. The snuffing portion is located on a shell area of the outer surface of the whole device, or the shell is provided with an outer shell and an inner shell, a hole-shaped area on the inner shell extends out of the outer shell or the outer shell to form the snuffing portion, for example, the end of the inner shell is provided with a suction pipe shape, and the suction pipe shape can extend out of the outer shell from the inside of the device to be used by a user.

In addition, for portability, it is preferred that the device be hand-held, i.e. in the manner that a single palm pinch can hold substantially the entire device, and that the housing be generally cylindrical in shape, i.e. having axially extending side surfaces and end surfaces at either end of the side surfaces, typically the length of the side surfaces extending axially being greater than the radial dimension of the end surfaces. The cylindrical shell can be cylindrical, square cylindrical, polygonal cylindrical or other regular or irregular shaped cylinder.

The housing is preferably of a long cylindrical shape in view of the ease of palm kneading, for example, the axial length of the housing is 3 times or more the radial dimension of the cross section of the housing. The cross section of the shell is a section of the shell taken perpendicular to the axial direction; when the respective cross sections of the housing in the axial direction are not constant, the cross sections having an average area are taken, and the cross sections are plural, and the cross section is taken near the midpoint of the axial length. The cross section is square, and the radial dimension of the cross section is the side length of the cross section; the cross section is circular, and the radial dimension of the cross section is the diameter of the circle; the cross-section is neither square nor circular, the radial dimension being taken as the square root of the cross-sectional area. In addition, to avoid the device being too slim to facilitate gripping, it is preferred that the axial length of the housing be less than 8 times the radial dimension of the cross-section.

The inventor of the invention fully researches the size of the palm of a user and the using habit of a patient, and finally designs the axial length of the shell to be between 40 mm and 120mm, preferably within the range of 50 mm to 80 mm; the length allows the thumb and the index finger of the user to pinch the upper end of the device on one hand, and enables the lower end of the device to be approximately positioned at the lower part of the palm on the other hand, so that the device can be in contact friction with the palm and can be just abutted against the palm to provide a palm control feeling for the user. In addition, the diameter range of the palm holding enclosure is generally 10-30 mm, so the radial dimension is preferably 12-20 mm, for example 14-18 mm when the medical nasal inhalation device is designed.

In addition, for better holding, a hand-holding part can be designed on the surface of the shell, and the hand-holding part is provided with a convex or concave or undulate curved surface to increase the friction force with the palm.

Of course, the device of the present invention may not necessarily be manufactured with the size and shape related limitations of the hand held device described above, but the above is only a preferred embodiment, and the device may be made with relatively large volume dimensions within the allowable range of various application scenarios and product design space. Regardless of the size and volume, the electronic atomization device to be protected by the present invention is a device that allows a user to inhale aerosol through nasal inhalation and the aerosol escapes from the device through heated evaporation to be inhaled by the user.
