Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, an electronic cigarette 1 is a device for heating related components by an electric current to atomize a liquid into vapor, i.e., smoke. The relevant components of the electronic cigarette 1 for atomizing the tobacco juice into smoke are, for example, an atomizing device shown in fig. 2. Referring to fig. 2 and 3, an embodiment of an atomizing device of the present application includes: cartridge tube 11, heat generating component 12, upper cover 13, base 14 and first seal 15.
The cartridge tube 11 is formed with a liquid storage chamber 111 and a smoke passage 112. Wherein the liquid storage chamber 111 is used for storing the smoke liquid. The heating component 12 is used for heating the smoke liquid stored in the liquid storage cavity 111 for atomization to form smoke. For example, the smoke in the liquid storage cavity 111 flows to the heating component 12 to be heated and atomized by the heating component 12. The smoke passage 112 is used to deliver smoke formed by the heat generating component 12 for inhalation by a user.
In the present embodiment, the upper cover 13 and the base 14 are fixed to each other to support the heat generating component 12 between the upper cover 13 and the base 14, that is, the heat generating component 12 is disposed between the upper cover 13 and the base 14, and the heat generating component 12 is fixed by the fixed fitting of the upper cover 13 and the base 14. The upper cover 13 is provided with a liquid inlet 131a, and the liquid inlet 131a is communicated with the liquid storage cavity 111. The smoke liquid in the liquid storage cavity 111 flows to the heating component 12 through the liquid inlet 131a. The atomizer is further provided with an air inlet opening 14a for guiding air into the atomizer. For example, an air inlet 14a is formed on the base 14 and is connected to the outside, so that air enters the atomization device through the air inlet 14a to drive the smoke to flow into the smoke channel 112.
In this embodiment, the first sealing member 15 is disposed between the upper cover 13 and the heat generating component 12, and is used to contact the upper cover 13 and the heat generating component 12 at the same time to seal, so as to avoid leakage from the connection position or contact position between the upper cover 13 and the heat generating component 12 when the smoke liquid flows from the liquid storage cavity 111 through the liquid inlet 131a and enters the heat generating component 12. In other words, the first seal 15 seals the connection or contact position between the upper cover 13 and the heat generating component 12. With further reference to fig. 3, an air guide channel 16 is formed between the first seal 15 and the heat generating component 12. The air guide passage 16 serves to guide air flowing in through the air intake hole 14a to the liquid storage chamber 111. Specifically, the air enters the base 14 from the air inlet hole 14a, then flows into the air guide channel 16, flows into the liquid inlet hole 131a through the air guide channel 16, and then enters the liquid storage cavity 111.
In the working process of the embodiment, the smoke liquid in the liquid storage cavity 111 of the cartridge tube 11 flows onto the heating component 12 through the liquid inlet 131a of the upper cover 13, the heating component 12 atomizes the smoke liquid into smoke by heating, and under the pressure generated by the inhalation of a user, air enters the atomization device from the air inlet 14a of the base 14 to generate air flow under the action of the pressure so as to drive the smoke to flow into the smoke channel 112, so as to be inhaled by the user.
In the prior art, the smoke liquid continuously flows into the heating component 12 for atomization, so that the air pressure in the liquid storage cavity 111 becomes low, and negative pressure is formed. Under the condition that the liquid storage cavity 111 forms the negative pressure, the smoke liquid enters into the heating component 12 and is atomized to be blocked, so that the smoke liquid is not smooth, meanwhile, the smoke liquid originally on the heating component 12 cannot flow in time, the scorched smell is possibly generated, and the use experience of the electronic cigarette is affected. In order to solve the problems in the prior art, in this embodiment, an air guide channel 16 is formed between the heating component 12 and the first sealing member 15 disposed between the upper cover 13 and the heating component 12, and the air guide channel 16 is used for guiding at least air flowing in through the air inlet hole 14a to the liquid storage cavity 111, so as to increase the air pressure in the liquid storage cavity 111, so that the problems of unsmooth liquid in smoke liquid caused by negative pressure in the liquid storage cavity 111 can be effectively avoided, the working efficiency of the atomizing device is improved, and the use experience of the electronic cigarette is improved.
In this embodiment, the cartridge tube 11 is, for example, in a hollow tubular shape, such as a cylindrical tube or an elliptic cylindrical tube, and the specific shape of the cartridge tube 11 may be designed according to the actual situation of the electronic cigarette 1. The smoke passage 112 is also, for example, tubular and extends along the length of the cartridge tube 11, and the smoke passage 112 is, for example, connected at one end to the mouthpiece 11a and at the other end to receive smoke generated by the heat generating component 12. A liquid storage cavity 111 is formed between the outer side wall of the flue gas channel 112 and the inner side wall of the cartridge tube 11. Wherein the liquid storage chamber 111 is used for storing the smoke liquid. Further, the cartridge tube 11 may be provided with a liquid adding hole (not shown) communicating with the liquid storage chamber 111 for adding liquid. When not in use, the smoke liquid adding hole is in a sealed state. Alternatively, the width of the cartridge tube 11 is gradually increased from the mouthpiece 11a to the heat generating component 12 and then is maintained. In other embodiments, the air inlet 114a may be formed on the mouthpiece 11a and communicate with the smoke channel 112, and under the pressure of the user sucking, air enters the smoke channel 11 through the air inlet 14a to form an air flow to drive the smoke to flow.
Referring to fig. 2 and 4, alternatively, the heat generating component 12 includes a porous ceramic liquid guide 121 and a heat generating member 122 disposed on a bottom surface 121b of the porous ceramic liquid guide 121. The porous ceramic liquid 121 is made of, for example, a porous ceramic material, which is generally a ceramic material sintered at high temperature from an aggregate, a binder, a pore-forming agent, and the like, and has a large number of porous structures communicating with each other and with the surface of the material. The porous ceramic material has the excellent performances of high porosity, stable chemical property, large specific surface area, small volume density, low thermal conductivity, high temperature resistance, corrosion resistance and the like. The air guide channel 16 is arranged, so that the problem that ventilation cannot be effectively performed under the condition that negative pressure is generated by absorbing smoke by a user due to the tortuous porous structure of the porous ceramic liquid guide 121 can be further avoided, the problem that the smoke smell is caused due to unsmooth liquid discharge of the porous ceramic liquid guide 121 due to the fact that ventilation cannot be performed by the porous structure is also avoided, the atomization efficiency of the atomization device is improved, and the use experience is improved.
Specifically, the porous ceramic liquid guide 121 is formed with a liquid guide groove 1211. For example, the porous ceramic liquid guide 121 is recessed toward the top surface 121a of the liquid storage chamber 111 to form a liquid guide groove 1211. The liquid guiding groove 1211 is used for receiving the tobacco liquid flowing in through the liquid inlet 131a. In a cross section parallel to the top surface 121a of the porous ceramic liquid guide 121, the cross section of the liquid guide groove 1211 gradually decreases in the depth direction of the liquid guide groove 1211. By forming the liquid guide groove 1211, it is possible to facilitate holding the smoke liquid while increasing the contact area between the smoke liquid and the porous ceramic liquid guide 121, and it is possible to improve the flow efficiency and speed of the smoke liquid.
In the present embodiment, the heat generating member 122 may be at least one of a heat generating coating, a heat generating circuit, a heat generating sheet, or a heat generating mesh. Specifically, the heating element 122 is disposed on a bottom 121b of the porous ceramic liquid guide 121 opposite to the liquid guide groove 1211, and the smoke liquid flows to the heating element 122 on the bottom 121b in the porous structure in the liquid guide groove 1211, and the heating element 122 is used for heating to atomize the smoke liquid to form smoke in connection with a power supply. In this embodiment, for example, the heating element 122 is a heating resistance wire, and the heating element 122 generates heat after being powered on, so that the smoke liquid flowing to the bottom surface 121b of the porous ceramic liquid guide 121 is atomized to generate smoke. In this embodiment, the heat generating element 122 may be disposed in a zigzag shape.
Referring to fig. 2 and 4, optionally, the heat generating component 12 further includes an electrode 123, where the electrode 123 is inserted in the bottom 121b of the porous ceramic liquid guide 121 and extends in a direction away from the bottom 121 b. That is, when the heat generating component 12 is fixed to the upper cover 13 and the base 14, the electrode 123 is inserted in the bottom surface 121b and extends in a direction toward the base 14. The electrode 123 is electrically connected to the heat generating member 122. The electrode 123 is used for connecting to a power supply. Of course, the number of the electrodes 123 may be 2 to connect the positive and negative poles of the power supply. The power source is, for example, a battery.
Referring to fig. 2 and 4, optionally, the upper cover 13 includes a guide portion 131 and a receiving portion 132 connected in sequence, and the guide portion 131 is formed with a liquid inlet hole 131a penetrating a top 1311 and a bottom 1312 of the guide portion 131. In this embodiment, the number of the liquid inlets 131a is two, and the two liquid inlets 131a are spaced apart and respectively correspond to the liquid storage cavities 111 on two sides of the flue gas channel 112. The liquid inlet 131a communicates with the liquid storage chamber 111 at a position of the top 1311 of the guide 131, and communicates with the liquid guide groove 1211 at a position of the bottom 1312 of the guide 131. Alternatively, the liquid inlet 131a is formed in an elliptical shape, and the cross-sectional area of the liquid inlet 131a is gradually reduced in the direction from the top 1311 to the bottom 1312 of the guide 131. In the present embodiment, the upper cover 13 may be integrally formed.
Referring to fig. 2 to 4, in the present embodiment, a side wall of the accommodating portion 132 is connected to the bottom 1312 of the guiding portion 131 to define an accommodating cavity 1321. The distance between the sidewall of the receiving part 132 and the edge of the liquid inlet 131a of the bottom 1312 of the guide part 131 is greater than 0, that is, the distance between the inner surface of the sidewall of the receiving part 132 (the surface facing the receiving chamber 1321) and the liquid inlet 131a is greater than 0, for example, 0.3mm, so that a portion of the bottom 1312 of the guide part 131 therebetween may be used to support the first sealing member 15 for sealing, so that the sealing effect of the first sealing member 15 is better, thereby avoiding leakage of smoke liquid. The receiving chamber 1321 is for receiving a part of the heat generating component 12, and the first sealing member 15 is supported between the guide 131 and the heat generating component 12 within the receiving chamber 1321 to seal. Specifically, the opposite side of the accommodation cavity 1321 from the bottom 1312 of the guide portion 131 is an opening, through which the first sealing member 15 and the porous ceramic liquid guide 121 enter the accommodation cavity 1321, and the first sealing member 15 is supported between the bottom 1312 of the guide portion 131 and the top surface 121a of the porous ceramic liquid guide 121, so that the first sealing member 15 seals the two, and can ensure that the smoke liquid does not leak from between the bottom 1312 of the guide portion 131 and the porous ceramic liquid guide 121, and thus directly enters the liquid guide groove 1211.
Optionally, the guiding portion 131 is further provided with an air outlet hole 131b, and the air outlet hole 131b is communicated with the top 1311 of the guiding portion 131. In this embodiment, the air outlet 131b is adjacent to the liquid inlet 131a and spaced apart from the liquid inlet 131a. The guide portion 131 further has a through hole 131c, and the through hole 131c penetrates a side surface 1313 of the guide portion 131 opposite to each other. In this embodiment, the side surface 1313 of the guide 131 may be, for example, a surface of the guide 131 that is not adjacent to the base sidewall 142. The through-holes 131c and the air outlet holes 131b penetrate each other to communicate, that is, the air outlet holes 131b may communicate the bottom 1312 and the side surface 1313 of the guide portion 131, so that the smoke can enter the smoke passage 112 through the through-holes 131c and the air outlet holes 131 b. In this embodiment, the air outlet 131b communicates with the flue gas channel 112, for example, the flue gas channel 112 is inserted into the air outlet 131b for fitting connection and sealing. Further, a guide groove 1322 is formed on the outer surface of the sidewall of the accommodating portion 132, the guide groove 1322 communicates with the through hole 131c of the guiding portion 131, and the guide groove 1322 extends from the communicating portion with the through hole 131c to one end of the accommodating portion 132 away from the guiding portion 131. Referring to fig. 2 and 4, optionally, the atomizing device further comprises a second seal 17. The second sealing member 17 may be provided in a sleeve shape, and is sleeved on at least the edge of the top 1311 of the upper cover 13 and the periphery of the guide portion 131, so as to seal between the cartridge tube 11 and the upper cover 13, so as to prevent the smoke liquid in the liquid storage cavity 111 from leaking. Further, when the second sealing member 17 is sleeved on the upper cover 13, the second sealing member 17 also seals between the smoke channel 112 and the air outlet 131b, so that on one hand, the smoke liquid is prevented from leaking from the air outlet, and on the other hand, the smoke is prevented from leaking. In this embodiment, the second seal 17 may be made of silicone and integrally formed.
Referring to fig. 2 and 4, the base 14 may optionally include a base bottom wall 141 and a base side wall 142 connected to the base bottom wall 141. For example, the base side walls 142 may be spaced apart and opposed, for example, the base side walls 142 shown in FIG. 4 are not annularly closed, and define a space 140 with the base side walls 142, the space 140 being adapted to receive the heat generating component 12. Wherein the receiving portion 132 is inserted into the space 140 and fixed to the base sidewall 142 such that the heat generating component 12 is fixed between the upper cover 13 and the base 14. When the accommodating portion 132 is fitted into the space 140, the guide groove 1322 can communicate with the space 140 and the through hole 131c, so that the space 140 communicates with the smoke passage 112. In this embodiment, the air intake hole 14a may be formed on the base bottom wall 141, penetrating the base bottom wall 141, or may be formed on the base side wall 142, or may be formed on both the base bottom wall 141 and the base side wall 142. In other embodiments, when the air inlet 14a is not formed on the base 14, the air inlet 14a, the flue gas channel 112, the air outlet 131b, the through hole 131c, the guiding slot 1322 and the space 140 are communicated, so that the air entering the air inlet 14a can still enter the space 140, and thus enter the liquid storage cavity 111 through the air guide channel 16. In this embodiment, for example, the base bottom wall 141 and the accommodating portion 132 are connected in a snap-fit manner, for example, a snap-fit groove (not labeled) is formed on the base bottom wall 141, a snap-fit block (not labeled) is disposed on the outer side wall 152 of the accommodating portion 132, the accommodating portion 132 is embedded into the space 140 of the base 14, and the snap-fit block and the snap-fit groove are in a fixed connection. Further, the guide groove 1322 of the accommodating portion 132 communicates the space 140 and the through hole 132c.
With continued reference to fig. 2 and 4, in this embodiment, the base 14 further includes an electrode mount 144.

The electrode hole 144a is formed in a blind hole form at one end of the electrode hole holder 144 toward the upper cover 13. The portion of the electrode hole seat 144 exposed from the other side surface of the base bottom wall 141 facing away from the upper cover 13 serves as a contact for connection with a power source. In the present embodiment, the electrode 123 of the heat generating component 12 is inserted into the electrode hole 144a of the electrode hole holder 144, and the electrode hole holder 144 is powered on to enable the heat generating element 122 to generate heat under the action of current. Further, the smoke liquid flows to the heating element 122 of the bottom surface 121b in the liquid guiding groove 1211 through the porous structure of the porous ceramic liquid guiding body 121, and the smoke liquid evaporates to form smoke under the heating action of the heating element 122, and the smoke is formed in the space 140 of the base 14. With continued reference to fig. 2 and 4, the base bottom wall 141 may be optionally provided with a vent hole 14b communicating with the outside. The base 14 further includes an air intake plate 143, and a plurality of air intake holes 14a are provided on the air intake plate 143. The air inlet hole 14a is communicated with the space 140 of the base 14 and the air vent 14b, so that the external air flow is sent between the base 14 and the heating component 12, namely, the space 140 from the air vent 14b and the air inlet hole 14a, and further the smoke generated by heating the smoke liquid by the heating element 122 arranged on the bottom surface 121b of the porous ceramic liquid guide 121 is taken away, and is sent to the smoke channel 112 in the space 140 through the guide groove 1322, the through hole 131c and the air outlet hole 131 b.

In the present embodiment, the first seal 15 is made of, for example, silicone or the like and is integrally molded.
The first case of the air guide passage 16 in this embodiment is as follows:
referring to fig. 2 to 4, optionally, the first sealing member 15 includes a top wall 151, where the top wall 151 is disposed between the top surface of the porous ceramic liquid guide 121 and the upper cover 13 around the liquid guide slot 1211, so that the liquid guide slot 1211 is exposed, and an air guide channel 16 is formed between an inner side surface of the top wall 151 facing the porous ceramic liquid guide 121 and the porous ceramic liquid guide 121.

The width H is, for example, a distance in the width direction in a direction perpendicular to the extending direction when the first air guide groove 1511 is provided in a stripe shape. By providing the depth D and the width H of the first air guide groove 1511 described above, it can be further ensured that the air guide passage 16 allows the air to circulate while avoiding or reducing the leakage of the smoke liquid.

Specifically, for example, the side wall 152 of the first seal 15 is perpendicular to the top wall 151. When the first sealing member 15 is sleeved on the porous ceramic liquid guide 121, the top wall 151 contacts the top surface 121a of the porous ceramic liquid guide 121, and the side wall 152 contacts the outer periphery of the outer side surface 121c of the porous ceramic liquid guide 121 for sealing. The sealing effect of the first sealing member 15 can be further ensured by providing the side wall 152 of the first sealing member 15, and the porous ceramic liquid guide 121 can be protected at the same time.
Optionally, a second air guiding groove 1521 is formed on the inner side surface of the sidewall 152 facing the porous ceramic liquid guiding body 121.

When the first sealing member 15 is sleeved on the porous ceramic liquid guide 121 and is assembled to the accommodating portion 132 of the upper cover 13, the air guide channel 16 is formed between the first air guide groove 1511 and the second air guide groove 1521 and the porous ceramic liquid guide 121. Specifically, the first air guide groove 1511 and the second air guide groove 1521 respectively form an air guide channel 16 communicating with the top surface 121a and the outer side surface 121c of the porous ceramic liquid guide 121, and air flowing in through the air inlet hole 14a of the base 14 flows into the liquid storage cavity 111 through the air guide channel 16 to balance the air pressure in the liquid storage cavity 111.

When the first sealing member 15 is sleeved on the porous ceramic liquid guide 121 and is assembled to the accommodating portion 132 of the upper cover 13, the air guide channel 16 is formed between the first air guide groove 1511 and the second air guide groove 1521 and the porous ceramic liquid guide 121. By providing the second air guide groove 1521 in a zigzag shape, leakage of the smoke liquid can be effectively avoided, and meanwhile, the flowing time of the smoke liquid entering the air guide channel 16 can be prolonged, so that the heated porous ceramic air guide body 121 can be atomized. Optionally, the second air guiding grooves 1521 are, for example, V-shaped, and the second air guiding grooves 1521 of the plurality of V-shapes are further arranged in a net shape, and are mutually communicated in a net shape, so that the smoke rises along the V-shape, but the V-shape design can generate a certain resistance to the leakage.

Wherein the outer side 121c of the porous ceramic liquid conductor 121 is provided with a step surface 121d facing away from the top surface. Specifically, when the porous ceramic liquid guide 121 is accommodated in the space 140 of the base 14, the outer side 121c of the porous ceramic liquid guide 121 opposite to the base side wall 142 is provided with a step surface 121d, and the step surface 121d faces the bottom 121b side of the porous ceramic liquid guide 121, opposite to the opening direction of the liquid guide groove 1211. When the first sealing member 15 is sleeved on the porous ceramic liquid guide 121, the bottom wall 153 surrounds the step surface 121d, and the bottom wall 153 contacts the support table 1421 of the base 14 and the step surface 121d to seal. By providing the bottom wall 153, the effect of the first sealing member 15 can be made better, and the first sealing member 15 can make the fit of the first sealing member 15 and the porous ceramic liquid guide 121 more stable by surrounding part of the porous ceramic liquid guide 121 with the top wall 151, the side wall 152 and the bottom wall 153.
Referring to fig. 7 and 8, optionally, the bottom wall 153 is formed with a third air guide groove 1531 toward the inner side of the step surface, and the number of the third air guide grooves 1531 is greater than or equal to 1.

Specifically, the third air guide groove 1531 communicates with the second air guide groove 1521 as in the second case and/or the third case, and when the first sealing member 15 is sleeved on the porous ceramic liquid guide 121, the third air guide groove 1531, the second air guide groove 1521 and the first air guide groove 1511 communicate with each other and form an air guide channel 16 with the porous ceramic liquid guide 121 for guiding the air flowing into the air inlet hole 14a of the base 14 to the liquid storage chamber 111.
Optionally, the third air guide recess 1531 has a depth of 0.1mm-0.3mm, optionally 0.15mm-0.25mm. The third air guide recess 1531 has a width of 0.5mm-1mm, optionally 0.7mm-0.8mm. Reference may be made to the first case for definition of the depth and width of the third air guide groove 1531.
