Description

Electronic cigarette drive module

【Technical field】

This case relates to a drive module of an electronic cigarette, especially a drive module applied to an electronic cigarette containing cigarette liquid.

【Background technique】

The use of electronic cigarettes, or so-called e-cigarettes, is rapidly expanding as an alternative to traditional smoking of real tobacco. As shown in Figures 1A, 1B, the electronic cigarette comprises components that can be assembled together and then installed in the housing 1 . The housing 1 includes a first housing 1a and a second housing 1b, which can be a thin-walled metal tube, such as stainless steel, with a length and diameter similar to that of a traditional tobacco cigarette. The components of the electronic cigarette include a drive module 2, a sensor 3 , atomization part 4 and liquid storage part 5. The driving module 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 near the sensor 3 . The atomizing part 4 and the liquid storage part 5 are installed in the second housing 1b, the atomizing part 4 is fixedly supported by a bracket 7, and the atomizing part 4 includes an electric heater 41 and a liquid that is sleeved on the electric heater 41 The permeable part 42 and a liquid conduction part 43 tightly matched with the liquid permeable part 42, the electric heater 41 is a hollow structure; and the liquid storage part 5 is installed in the second housing 1b, and has a gas flow passage 51 inside , and there is a liquid storage container 52 on the periphery of the channel 51, and the liquid conducting part 43 is sleeved on the liquid permeable part 42, and the conduction part 431 of the liquid conducting part 43 is in contact with the liquid storing container 52. Therefore, the cigarettes in the liquid storing container 52 The liquid is absorbed and permeates into the liquid permeable member 42 . A connecting part 10 is provided between the atomizing part 4 and the sensor 3 to form an air flow circuit for communicating with the channel 51 of the liquid storage part 5, so that external air can enter through at least one air inlet 1c, pass through the sensor 3 and then pass through the electric heater 41 And it is introduced into the channel 51 of the liquid storage part 5 . Wherein, the connection component 10 can be used for electrical connection and air intake connection. In addition, the components of the electronic cigarette are further provided with an electrode ring 8, which is electrically connected to the 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 part 10 and the sensor 3. The entire circuit is turned on or off depending on the presence or absence of airflow detected. Finally, a suction nozzle 9 is assembled at one end of the second casing 1 b, and communicates with the channel 51 of the liquid storage part 5 . When the user inhales the mouthpiece 9, the gas in the electronic cigarette flows. At this time, the sensor 3 is connected to the circuit, and the electric heater 41 is started for heating. When the user stops inhaling, the gas stops flowing, and the sensor 3 closes the circuit so that the electric heater 41 stops heating. In this way, the cigarette liquid penetrates from the liquid storage container 52 to the liquid permeable part 42 through the conduction part 431 of the liquid conducting part 43, and when the user inhales air through the suction nozzle 9, the gas in the electronic cigarette flows, and the sensor 3 opens the circuit according to the air flow , the drive module 2 supplies power to the electrode ring 8 to start the electric heater 41 for heating, and the cigarette liquid that permeates the liquid permeable part 42 is atomized by the electric heater 41, and the user can suck the liquid storage part 5 through the suction nozzle 9 Atomized smoke in channel 51.

The design of the above-mentioned electronic cigarette in which the cigarette liquid penetrates into the liquid permeable part 42 through the conduction part 431 of the liquid conduction part 43 has the following problems: First, because the conduction part 431 of the liquid conduction part 43 cannot accurately control the penetration amount, resulting in uneven adsorption of cigarette liquid by the liquid permeable part 42, resulting in the part of the liquid permeable part 42 containing a small amount of cigarette liquid, resulting in uneven droplets, which will produce burnt smoke after being heated by the electric heater 41, which will make the smoker feel Unpleasant taste; secondly, because the conduction part 431 of the liquid conducting part 43 cannot accurately control the permeation amount, when the suction nozzle 9 faces upwards, the force of gravity goes downwards so that the cigarette liquid in the liquid storage container 52 cannot completely stop the permeation The amount of flow entering the liquid-permeable part 42 causes the liquid-permeable part 42 to drip cigarette liquid to the connecting part 10 when the liquid-permeable part 42 is full, and leak out from the air inlet 1c through the sensor 3, causing oil seepage.

In addition, there is still a certain gap between the feeling of smoking electronic cigarettes and real cigarettes. When people smoke real cigarettes, they often take fast, short, and vigorous inhalation methods, but when using electronic cigarettes and evaporators, they can only inhale with gentle force for longer inhalation time. The reason is that real smoke will inhale a large amount of oxygen when the user inhales quickly, causing the tobacco to burn and atomize faster, helping the user to inhale the amount of smoke he wants. However, it is known that electronic cigarettes cannot change the power supplied to the electric heater to adjust the heating speed during the smoking process. What's more, if the heating is too fast, the e-liquid in the atomizer will be atomized too quickly, and if The above-mentioned known electronic cigarettes rely on the power of the siphon phenomenon to supply liquid too slowly to match the speed of atomization of the e-liquid, resulting in problems such as insufficient vapor volume evaporated by the atomizer or burnout of the atomizer. Based on the fact that the power provided by the general electronic cigarette to the atomizer is constant, the user has to prolong the inhalation time and inhale gently, so that the atomizer has enough time to heat up and atomize the e-liquid. It can be seen that there are still many shortcomings in the current electronic cigarettes. The above-mentioned problems lead to significant differences between real cigarettes and electronic cigarettes, which is not conducive to smokers choosing electronic cigarettes instead of real cigarettes.

In view of this, how to develop an electronic cigarette that can improve the above-mentioned lack of known electronic cigarette technology, develop an electronic cigarette that can replace a real cigarette, and provide an electronic cigarette drive module that can be used by the industry is an urgent problem to be solved at present. .

The sleeve is inserted, and the bottom edge of the valve cover 62 has a chamfer 623 , and the outer diameter of the valve cover 62 is slightly larger than the inner wall 671 of the outer cylinder 67 .

Therefore, referring to Fig. 5A and Fig. 5B, the valve body 63, the valve diaphragm 64, the valve cavity body seat 65, and the actuator 66 are sequentially stacked and placed in the inner wall 671 of the outer cylinder 67, so that the entire stacked structure bears On the convex ring structure 672 of the outer cylinder 67, the outer diameter of the valve cover body 62 is designed to be slightly larger than the inner wall 671 of the outer cylinder 67, and the chamfer 623 can be smoothly introduced into the inner wall 671 of the outer cylinder 67, and they are closely matched with each other. Assembling and combining positioning valve body 63, valve diaphragm 64, valve cavity seat 65, and actuator 66 are sequentially stacked to form fluid delivery device 6, and actuator 66 can also be placed in the hollow space of inner wall 671 of outer cylinder 67, The piezoelectric element 662 drives the vibrating plate 661 to reciprocate vertically and resonate when receiving the applied voltage, so that the fluid delivery device 6 does not need to be locked and assembled with locking elements (such as screws, nuts, bolts, etc.).

As shown in Figure 11, in the fluid conveying device 6 of this case, the inlet valve passage 651 of the valve cavity body seat 65 is arranged corresponding to the inlet opening 6311 of the valve body 63, and the valve sheet 641a of the valve diaphragm 64 is used to close the valve between them. The role of the structure, and the valve piece 641a covers the inlet opening 6311 of the valve body 63, and at the same time fits the convex structure 6343 of the valve body 63 to generate a preforce (Preforce) effect, which helps to produce a greater pre-closing effect , to prevent backflow, and the outlet valve channel 652 is set corresponding to the outlet opening 6321 of the valve body 63, and the valve piece 641b of the valve membrane 64 is used to close the valve structure, and the valve piece 641b of the valve membrane 64 Cover the outlet valve channel 652 of the valve cavity seat 65, and at the same time fit the convex structure 6521 of the valve cavity seat 65 to produce a preforce (Preforce) effect, which helps to produce a greater pre-capping effect to prevent The counterflow pressure chamber 657, so when the fluid conveying device 6 constituted in this case does not operate, there will be no countercurrent effect between the inlet channel 631 and the outlet channel 632 of the valve body 63 .

From the above description, it can be seen that the fluid delivery device 6 in this case is implementing the operation of fluid delivery. As shown in FIG. The volume of the pressure chamber 657 will increase, thereby generating a suction force, so that the valve plate 641a of the valve diaphragm 64 is subjected to a suction force to open quickly, so that a large amount of fluid can be sucked in from the inlet passage 631 on the valve body 63, and flow through the valve. The inlet opening 6311 of the body 63, the hollow hole 643a of the valve diaphragm 64 (not marked in FIG. 12A, see FIG. 8), and the inlet valve channel 651 of the valve cavity body seat 65 flow into the pressure chamber 657 for temporary storage, while the outlet valve The passage 652 is also subjected to suction, and the valve sheet 641b of the valve membrane 64 is subjected to this suction, and is supported by the extension bracket 642b to flatten downward and close to the convex structure 6521 to present a closed state.

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 will deform the vibrating plate 661 upward, and at this time, the pressure chamber 657 shrinks and the volume decreases, so that the pressure chamber The fluid in 657 is squeezed, and at the same time, the inlet valve channel 651 is thrust, and the valve plate 641a of the valve diaphragm 64 is subjected to this thrust, and the entire upward flatness is produced by the support of the extension bracket 642a and is close to the convex structure 6343 It is in a closed state, and the fluid cannot flow back through the inlet valve channel 651, and at this time, the outlet valve channel 652 is also subjected to thrust, and the valve plate 641b of the valve diaphragm 64 is subjected to this thrust, and the entire upward separation is generated by the support of the extension bracket 642b. The state of being flat against the protrusion structure 6521 is in an open state, and the fluid can flow out of the pressure chamber 657 through the outlet valve passage 652, and pass through the outlet valve passage 652 of the valve cavity body seat 65 and the hollow on the valve diaphragm 64 The hole 643b (not shown in FIG. 12B , see FIG. 8 ), the outlet opening 6321 and the outlet channel 632 on the valve body 63 flow out of the fluid delivery device 6 , thus completing the fluid delivery process. By repeating the operations shown in Figure 12A and Figure 12B , the fluid can be delivered continuously. In this way, the fluid delivery device 6 of this case can prevent the fluid from backflowing during the delivery process and achieve high-efficiency delivery.

Therefore, when the fluid conveying device 6 is driven by the voltage control provided by the control board 22, the cigarette liquid can be quantitatively delivered by the liquid storage part 5, and can be used as a switch to control the supply and delivery of the cigarette liquid in the liquid storage part 5, so that the cigarette liquid can be quantitatively output. , and lead in the catheter tube 44, under the same pressure, through a plurality of through holes 442 can output evenly permeate outside the catheter tube 44, to produce uniform droplet, also make the outer content of the catheter tube 44 full when it can be controlled Turn off the delivery, so that the fluid delivery device 6 is combined with the setting of the atomizing part 4 to form a controllable switch to accurately control the amount of cigarette liquid penetrating the atomizing part 4, so as to solve the problem of uneven smoke taste caused by the known electronic cigarette technology. and oil leakage problems.

From the above, it can be seen that the specific implementation of the electronic cigarette of this case is as follows. When the user inhales through the opening 92 of the suction nozzle 9, the gas in the electronic cigarette flows. At this time, the sensor 3 is connected to the circuit, and the electric heater 41 is started. Heating; when the user stops inhaling through the opening 92 of the suction nozzle 9, the gas stops flowing, and the sensor 3 closes the circuit, so that the electric heater 41 stops heating; , forming a controllable switch to accurately control the amount of cigarette liquid penetrating the atomizing part 4, and the cigarette liquid is controlled by the liquid storage part 5 through the fluid delivery device 6 to quantitatively infiltrate outside the catheter 44. When the user uses the suction nozzle 9 When the opening 92 inhales air, the gas in the electronic cigarette flows, the sensor 3 opens the entire circuit according to the air flow, the driving module 2 supplies power to the heating module 23 to start the electric heater 41 to heat, and can control the quantitative penetration of the cigarette liquid into the catheter 44, and the cigarette liquid is quantitatively delivered to the electric heater 41 to generate atomized smoke, and the atomized smoke is exported from the suction nozzle 9 for the user to smoke. In addition, when the user inhales through the opening 92 of the suction nozzle 9, the air pressure sensor 32 can be used to monitor the pressure of the airflow according to the suction pressure of the user, and the output signal can be adjusted to adjust the control signal of the control board 22 to adjust the fluid delivery. The driving frequency of the device 6 and the driving power of the electric heater 41 are used to change the atomization speed of the quantitative cigarette liquid and the speed of the liquid supply, so that the user can quickly suck a large amount of atomized smoke, and can also take a sip When taking another puff, the amount and concentration of atomized smoke in each puff can be kept the same.

To sum up, this case provides a drive module for electronic cigarettes, which mainly controls the fluid delivery device to form a controllable switch to accurately control the amount of cigarette liquid penetrating the atomization components, and a sensor is installed. When the sensor senses the airflow, the sensor The airflow pressure sends a control signal to the control board of the drive module, so that the control board controls the power board to calculate a specific voltage value according to the control signal, and adjusts the voltage of the driving power provided by the battery through the connection interface to the specific voltage value, and through the control The plate drives the fluid conveying device to start to act, and the cigarette liquid in the liquid storage part is exported from the input channel, and delivered to the catheter through the output channel, and penetrates out of the catheter through a plurality of through holes to control the quantity of the cigarette liquid The atomized smoke is generated on the electric heater delivered to the atomizing part, and is sucked by the user through the opening of the nozzle; when the sensor detects that the air flow stops, the sensor stops sending a control signal to the drive module, so that the fluid delivery device stops delivering Cigarette liquid to stop electronic cigarettes from functioning. Therefore, the sensor monitors the airflow pressure, adjusts the output signal to adjust the control signal of the control board, adjusts the drive frequency of the fluid delivery device and the drive power of the heater module to change the atomization speed and liquid supply of the e-liquid. The speed and the anti-backflow conveying operation of the fluid conveying device can achieve high-efficiency transmission, so as to solve the problems of uneven smoke taste and oil leakage caused by the known electronic cigarette technology. Therefore, the e-cigarettes in this case are of great value for industrial application, so please file an application in accordance with the law.
