Description

Driving module of electronic cigarette

[ technical field ] A method for producing a semiconductor device

The present disclosure relates to a driving module for an electronic cigarette, and more particularly, to a driving module for an electronic cigarette containing cigarette liquid.

[ 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 components that can be assembled together and then installed within the housing 1. The housing 1 comprises a first housing 1a and a second housing 1b which 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 drive module 2, a sensor 3, an atomizer means 4 and a liquid storage means 5. The driving module 2 and the sensor 3 are installed in the first housing 1a, and at least one air inlet 1c is disposed on the first housing 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 cigarette liquid in the reservoir 52 is absorbed and permeated into the liquid permeable member 42. A connecting part 10 is arranged between the atomizing part 4 and the sensor 3 to form an air flow circuit which is communicated with the channel 51 of the liquid storage part 5, so that the external 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. Wherein the connecting member 10 can be used for electrical connection and air inlet connection. In addition, the element of the electronic cigarette is further provided with an electrode ring 8 electrically connected to two lead wires (not shown) of the electric heater 41, respectively, the electrode ring 8 is electrically connected to the driving module 2 through the connecting member 10 and the sensor 3, and the sensor 3 opens or closes the entire circuit according to the presence or absence of the detected air flow. Finally, a suction nozzle 9 is assembled to one end of the second housing 1b, and communicates with the passage 51 of the liquid storage member 5. When a user inhales the mouthpiece 9, air in 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 into the liquid permeating part 42 from the liquid storage container 52 through the conducting part 431 of the liquid conducting part 43, when the user inhales air again through the suction nozzle 9, the air in the electronic cigarette flows, the sensor 3 opens the circuit according to the air flow, the driving module 2 supplies power to the electrode ring 8 to start the electric heater 41 to heat, the cigarette liquid permeating into the liquid permeating part 42 is atomized through the electric heater 41, and the user can inhale the atomized cigarette 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 into the liquid permeable member 42 from the conducting portion 431 of the liquid conducting member 43 has problems that, firstly, the permeation amount cannot be precisely controlled by the conducting portion 431 of the liquid conducting member 43, and the liquid permeable member 42 adsorbs the cigarette liquid unevenly, so that the liquid permeating member 42 contains a portion with a small cigarette liquid amount, and the liquid droplets are not uniform, and the smoker feels uncomfortable in taste due to the generation of scorching smoke when heated by the electric heater 41; second, also because the conducting portion 431 of the liquid conducting member 43 cannot accurately control the amount of penetration, when the suction nozzle 9 is facing upward, the gravity force will cause the cigarette liquid in the liquid storage container 52 to not completely stop the amount of flow penetrating into the liquid penetrating member 42, and when the liquid penetrating member 42 is full, the cigarette liquid will drip to the connecting member 10 and leak out from the air inlet 1c through the sensor 3, causing the problem of oil leakage.

In addition, the feeling of smoking an electronic cigarette and a real cigarette still has a certain gap. People often adopt a quick, short and forceful suction mode when smoking a real cigarette, but only the suction time is prolonged to suck the real cigarette softly when using an electronic cigarette and a vaporizer. The reason is that real cigarettes, when the user inhales quickly, will inhale a large amount of oxygen, causing an increase in the speed of combustion and atomization of the tobacco, thereby helping the user to inhale his desired amount of smoke. However, the conventional electronic cigarette cannot change the power of the power source transmitted to the electric heater to adjust the heating speed during smoking, and further, the heating speed is too fast, which results in too fast atomization of the tobacco tar in the atomizer, and the liquid supply speed of the conventional electronic cigarette due to the siphon phenomenon is too slow to match with the atomization speed of the tobacco tar, which results in insufficient evaporation of the atomizer or burnout of the atomizer. Since the power supply to the atomizer is constant based on a typical electronic cigarette, the user can only have enough time for the atomizer to heat and atomize the tobacco tar by drawing the cigarette gently for a long time. It can be seen that the existing electronic cigarette still has many disadvantages, and the above problems result in significant difference between the real cigarette and the electronic cigarette, which is not beneficial for smokers to choose the electronic cigarette to replace the real cigarette.

In view of the above, how to develop an electronic cigarette that can improve the above-mentioned technical deficiencies of the known electronic cigarette, develop an electronic cigarette that can replace a real cigarette, and provide a driving module of an electronic cigarette that can be used in industry is a problem that needs to be solved urgently.

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.).

The fluid can be continuously transported by repeating the operations shown in fig. 12A and 12B, so that the fluid transporting device 6 of the present invention can achieve efficient transportation without causing backflow during the transportation process.
