Description

Electronic cigarette

[ technical field ] A method for producing a semiconductor device

The present disclosure relates to an electronic cigarette, and more particularly, to an electronic cigarette with a micro-pump structure.

[ background of the invention ]

The use of electronic cigarettes, or so-called electronic cigarettes, is rapidly expanding as a replacement for traditional real tobacco smoking cigarettes. As shown in fig. 1A, 1B, the electronic cigarette includes elements that can be assembled together and then mounted within a first housing 1A and a second housing 1B. The first and second housings 1a, 1b may be a thin-walled metal tube, such as stainless steel, having a length and diameter similar to a conventional tobacco cigarette, the elements of which include a power supply device 2, a sensor 3, an atomizer means 4 and a liquid storage means 5. The power supply device 2 and the sensor 3 are installed in the first casing 1a, and at least one air inlet 1C is disposed on the first casing 1a in a region close to the sensor 3. The atomization component 4 and the liquid storage component 5 are arranged in the second shell 1b, the atomization component 4 is fixedly supported by a bracket 7, the atomization component 4 comprises an electric heater 41, a liquid permeating component 42 sleeved on the electric heater 41 and a liquid conducting component 43 tightly matched with the liquid permeating component 42, and the electric heater 41 is of a hollow structure; and the liquid storage part 5 is installed in the second casing 1b, and has a passage 51 inside through which gas flows, and a reservoir 52 at the periphery of the passage 51, and the liquid conductive member 43 is fitted over the liquid permeable member 42, and the conducting portion 431 of the liquid conductive member 43 is in contact with the reservoir 52, so that the cigarette liquid on the reservoir 52 is absorbed and permeated into the liquid permeable member 42. An air inlet connecting part 7 is arranged between the atomizing part 4 and the sensor 3 to form an air flow loop which is communicated with the channel 51 of the liquid storage part 5, so that outside air can enter from at least one air inlet 1c, pass through the sensor 3 and then be guided into the channel 51 of the liquid storage part 5 through the electric heater 41. In addition, the electronic cigarette is further provided with an electrode ring 8 electrically connected to two leads of the electric heater 41, respectively, the electrode ring 8 is electrically connected to the power supply device 2 through the connection of the air inlet and electrical connection member 10 and the sensor 3, the sensor 3 opens or closes the entire circuit according to the air flow, and the final suction nozzle 9 is assembled to one end of the second housing 1b and the passage 51 of the liquid storage member 5. When a user inhales, the gas within the electronic cigarette flows. At this time, the sensor 3 turns on the electric circuit, and the electric heater 41 is activated to heat. When the user stops inhaling, the gas stops flowing and the sensor 3 closes the circuit to stop the electric heater 41 from heating. Thus, the cigarette liquid permeates from the liquid storage container 52 to the liquid permeating part 42 through the conducting part 431 of the liquid conducting part 43, when the user inhales air from the suction nozzle 9, the air in the electronic cigarette flows, the sensor 3 opens the whole circuit according to the air flow, the power supply device 2 supplies power to the electrode ring 8 to start the electric heater 41 to heat, the cigarette liquid permeates to the liquid permeating part 42 to generate atomization through the electric heater 41, and the user can inhale the atomized smoke in the channel 51 of the liquid storage part 5 through the suction nozzle 9.

The above-mentioned design of the electronic cigarette in which the cigarette liquid permeates from the conducting portion 431 of the liquid conducting member 43 to the liquid permeating member 42 has the following problems:

1. since the penetration amount cannot be precisely controlled by the conducting portion 431 of the liquid-transmitting member 43, the liquid-permeating member 42 adsorbs the cigarette liquid unevenly, so that the liquid-permeating member 42 contains a small amount of the cigarette liquid, and the liquid drops are unevenly distributed, thereby generating scorching smoke by heating with the electric heater 41, and causing the smoker to feel uncomfortable.

2. Because the conductive portion 431 of the liquid conductive member 43 cannot accurately control the amount of penetration, especially when the suction nozzle 9 is upward, the gravity force is downward to cause the cigarette liquid in the liquid storage container 52 at the periphery of the channel 51 of the liquid storage member 5 to not completely stop the amount of the liquid permeable member 42, so that when the liquid permeable member 42 is full, the cigarette liquid can drip to the air inlet and connecting member 10 and then leak out from the at least one air inlet 1c through the sensor 3, thereby causing the oil leakage problem.

In addition, there is still some gap in the feel of electronic cigarettes and real cigarettes, for example, people are accustomed to taking quick short and hard puffs when smoking cigarettes, rather than long soft puffs when electronic cigarettes and vaporizers are taken. This is because real tobacco inhales a large amount of oxygen when the user inhales quickly, which results in a faster burning and atomizing rate of the tobacco, and the user can quickly inhale the amount of smoke he wants. However, the electronic cigarette cannot adjust the power supply to the electric heater and the heating speed when smoking, if the heating speed is too high, the tobacco tar in the atomizer is atomized too fast, and the liquid supply of the electronic cigarette is too slow due to the siphon phenomenon, and finally the problems of insufficient smoke evaporated by the atomizer or burnout of the atomizer are caused. The power supply to the atomizer of a conventional electronic cigarette is constant, and the user must take a gentle puff for the atomizer to heat up enough time to atomize the tobacco tar.

In view of the above, how to develop an electronic cigarette that can improve the above-mentioned technical deficiencies of the known electronic cigarette and replace the actual cigarette is a problem that needs to be solved urgently.

Referring to fig. 5A and 5B, the actuator 66 is assembled by a vibrating plate 661 and a piezoelectric element 662, wherein the piezoelectric element 662 is attached and fixed on a surface of the vibrating plate 661. In the present embodiment, the vibrating plate 661 is made of metal, and the piezoelectric element 662 is made of piezoelectric powder of lead zirconate titanate (PZT) series with high piezoelectric number, and is attached to the vibrating plate 661, so that the piezoelectric element 662 is driven to deform by applying a voltage, and the vibrating plate 661 is driven to vibrate and deform in a vertical reciprocating manner along with the applied voltage, so as to drive the fluid conveying device 6 to operate.

As is apparent from the above description, the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 constitute the main structure of the fluid transport device 6 for guiding the transport fluid in and out. However, the main subject of the present invention is how to position the stacked and combined structure, and the locking and positioning assembly without using locking elements (such as screws, nuts, bolts, etc.). Therefore, the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 are sequentially stacked inside the outer cylinder 67 by using the design of the valve cover 62 and the outer cylinder 67, and the valve cover 62 is directly fitted inside the outer cylinder 67 to be positioned and assembled.

Thus, referring to fig. 5A and 5B, the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 are sequentially stacked and then placed in the inner wall 671 of the outer tube 67, the entire laminated structure is carried on the collar structure 672 of the outer tube 67, so that the valve cover 62 can be smoothly guided into the inner wall 671 of the outer tube 67 by the chamfer 623 due to the design that the outer diameter is slightly larger than the inner wall 671 of the outer tube 67, the positioning valve body 63, the valve diaphragm 64, the valve cavity seat 65 and the actuator 66 are assembled and combined in a tight fit manner to form the fluid conveying device 6 in a stacking manner, the actuator 66 can also be located in the hollow space of the inner wall 671 of the outer tube 67, and the piezoelectric element 662 is applied with voltage to drive the vibrating plate 661 to reciprocate vertically to generate deformation resonance, so as to achieve the purpose of locking and positioning the assembled fluid delivery device 6 without using a locking element (such as a screw, a nut, a bolt, etc.).

As shown in fig. 11, in the fluid delivery device 6 of the present invention, the inlet valve passage 651 of the valve chamber seat 65 is disposed corresponding to the inlet opening 6311 of the valve body 63, and the valve plate 641a of the valve diaphragm 64 is used to seal the inlet opening 6311 of the valve body 63, and the valve plate 641a covers the inlet opening 6311 of the valve body 63, and the convex portion structure 6343 of the valve body 63 is used to generate a preload (preload) effect, which helps generate a greater preload effect to prevent the reverse flow, while the outlet valve passage 652 is disposed corresponding to the outlet opening 6321 of the valve body 63, and the valve plate 641b of the valve diaphragm 64 is used to seal the outlet valve passage 652 of the valve chamber seat 65, and the convex portion structure 6521 of the valve chamber seat 65 is used to generate a preload (preload) effect, which helps generate a greater preload effect, the fluid delivery device 6 is constructed so that no backflow occurs between the inlet channel 631 and the outlet channel 632 of the valve body 63 when the fluid delivery device is not actuated by preventing the backflow of the pressure chamber 657.

As can be seen from the above description, in the fluid conveying device 6, when the piezoelectric element 662 of the actuator 66 is actuated by applying a voltage to deform the vibrating plate 661 to deform downward, the volume of the pressure chamber 657 increases, so that a suction force is generated, the valve plate 641a of the valve diaphragm 64 is rapidly opened by a suction force, a large amount of fluid can be sucked from the inlet channel 631 of the valve body 63, and flows through the inlet opening 6311 of the valve body 63, the through hole 643a of the valve diaphragm 64, the inlet valve channel 651 of the valve chamber seat 65 to the pressure chamber 657 for temporary storage, and the suction force is also applied to the outlet valve channel 652, and the valve plate 641b of the valve diaphragm 64 is supported by the extending bracket 642b to generate a closed state of the whole downward flat abutting against the convex portion structure 6521.

Thereafter, as shown in fig. 12B, when the direction of the electric field applied to the piezoelectric element 662 is changed, the piezoelectric element 662 deforms the vibrating plate 661 to deform upward, the pressure chamber 657 contracts to reduce the volume, the fluid in the pressure chamber 657 is compressed, the valve passage 651 receives a thrust force, the valve piece 641a of the valve diaphragm 64 receives the thrust force, the valve piece 641B of the valve diaphragm 64 is supported by the extension bracket 642a to be entirely in flat contact with the protrusion structure 6343 to be in a closed state, the fluid cannot flow backward through the valve passage 651, the valve passage 652 receives the thrust force, the valve piece 641B of the valve diaphragm 64 receives the thrust force, the valve piece 42B is supported by the extension bracket 42B to be entirely out of flat contact with the protrusion structure 6521 to be in an open state, and the fluid can flow out of the pressure chamber 657 through the valve passage 652 and pass through the valve passage 652 of the valve seat 65, The hollow-out hole 643B of the valve membrane 64, the outlet opening 6321 and the outlet channel 632 of the valve body 63 flow out of the fluid delivery device 6, so that the fluid delivery process is completed, and the operations shown in fig. 12A and fig. 12B are repeated to continuously deliver the fluid, so that the fluid delivery device 6 of the present invention can achieve high-efficiency delivery without causing backflow during the delivery process.
