Description

electronic cigarette

【Technical field】

This case relates to an electronic cigarette, especially an electronic cigarette with a micropump structure.

【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 and 1B, the electronic cigarette comprises components that can be assembled together and then installed in the first housing 1a and the second housing 1b. The first shell 1a and the second shell 1b 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 power supply device 2, a sensor 3, an atomizing component 4 and Liquid storage part 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 near the sensor 3 area. 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 component 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 cigarette on the liquid storing container 52 The liquid is absorbed and permeates into the liquid permeable member 42 . An air intake and electrical connection 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 5 is introduced into the channel 51 of the liquid storage member 5 . 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 of the electric heater 41 respectively. The electrode ring 8 is electrically connected to the power supply device 2 through the connection between the air intake and the electrical connection part 10 and the sensor 3, and the sensor 3 Open or close the entire circuit according to the air flow, and the last suction nozzle 9 is assembled at one end of the second housing 1b, and communicates with the channel 51 of the liquid storage part 5. When the user inhales, the gas inside the e-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 is infiltrated into the liquid permeable part 42 from the liquid storage container 52 through the conduction part 431 of the liquid conducting part 43. When the user inhales air through the suction nozzle 9, the gas in the electronic cigarette flows, and the sensor 3 opens the entire electronic cigarette according to the air flow. circuit, the power supply device 2 supplies power to the electrode ring 8 to start the electric heater 41 for heating, and the cigarette liquid penetrates into the liquid penetrating part 42 and then atomizes through the electric heater 41, and the user can inhale the liquid storage part 5 through the suction nozzle 9 The atomized smoke of the channel 51.

The cigarette liquid of the above-mentioned electronic cigarette penetrates into the design of the liquid permeable part 42 through the conduction part 431 of the liquid conducting part 43, and there are the following problems:

1. Because the conduction part 431 of the liquid conducting part 43 cannot accurately control the permeation amount, the liquid penetrating part 42 absorbs the cigarette liquid unevenly, resulting in the part of the liquid penetrating part 42 containing a small amount of cigarette liquid, resulting in uneven liquid droplets , the electric heater 41 is heated to produce burnt smoke, and the smoker will feel discomfort in the mouthfeel.

2. Because the conduction part 431 of the liquid conducting part 43 cannot accurately control the amount of penetration, especially when the suction nozzle 9 is facing upwards, the gravity will go down, causing the cigarette liquid in the liquid storage container 52 on the periphery of the channel 51 of the liquid storage part 5 to be unable to completely Stop the amount of the penetrating liquid penetrating part 42, so that when the permeating liquid penetrating part 42 is full, it will drop the cigarette liquid holder 7 and reach the air intake and electrical connection part 10, pass through the sensor 3 and then leak out from at least one air inlet 1c, resulting in Oil seepage problem.

In addition, there is still some gap between e-cigarettes and real cigarettes. For example, when people smoke, they will get used to taking quick, short and hard puffs, instead of taking long and gentle puffs in e-cigarettes and vaporizers. This is because real smoke will inhale a large amount of oxygen when the user inhales quickly, causing the tobacco to burn and atomize faster, and the user can quickly inhale the amount of smoke he wants. However, electronic cigarettes have no way to change and adjust the power and heating speed sent to the electric heater when smoking. If the heating is too fast, it will cause the smoke oil in the atomizer to atomize too fast, and as the above-mentioned known electronic cigarettes The supply of liquid by the power of siphon phenomenon will be too slow, which will eventually lead to problems such as insufficient amount of vapor evaporated by the atomizer or burnout of the atomizer. Therefore, the power delivered to the atomizer by general electronic cigarettes is constant, and the user must inhale gently for a long time to allow the atomizer to have enough time to heat up and atomize the e-liquid. Therefore, the current existing atomized electronic cigarettes There are still many problems and disadvantages, the above-mentioned problems lead to significant differences between real cigarettes and electronic cigarettes of smokers, which is not conducive to smokers to choose 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 and develop an electronic cigarette that can replace real cigarettes is an urgent problem to be solved at present.

In this embodiment, the vibrating plate 661 is made of metal, and the piezoelectric element 662 can be made of high-voltage lead zirconate titanate (PZT) series piezoelectric powder to be attached and fixed on the vibrating plate 661. The voltage is applied to drive the piezoelectric element 662 to deform, so that the vibrating plate 661 also undergoes vertical reciprocating vibration and deformation to drive the action of the fluid delivery device 6 .

However, how to position the stacked and combined structure without locking and locating the assembly with locking elements (such as screws, nuts, bolts, etc.) is the main subject to be implemented by the utility model. Therefore, the design of the valve cover 62 and the outer cylinder 67 is adopted below, and the valve body 63, the valve diaphragm 64, the valve cavity body seat 65, and the actuator 66 are sequentially stacked inside the outer cylinder 67, and then the valve cover 62 is directly tightly matched to the inner positioning assembly of the outer cylinder 67 for illustration.

Please refer to FIG. 5A , FIG. 5B and FIG. 9 , the outer cylinder 67 is made of metal, has an inner wall 671 surrounding a hollow space, and the bottom of the inner wall 671 of the outer cylinder 67 has a protruding ring structure 672 .

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 is carried on the On the convex ring structure 672 of the outer cylinder 67, the outer diameter of the valve cover 62 is designed to be slightly larger than the inner wall 671 of the outer cylinder 67. The chamfer 623 can be smoothly introduced into the inner wall 671 of the outer cylinder 67, and the mutual tight fit assembly The valve body 63, the valve diaphragm 64, the valve cavity seat 65, and the actuator 66 are sequentially stacked together to form the fluid delivery device 6, and the actuator 66 can also be pressed in the hollow space of the inner wall 671 of the outer cylinder 67. The electrical element 662 drives the vibrating plate 661 to reciprocate vertically to 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, the fluid conveying device 6 constituted in this case, the inlet valve channel 651 of the valve cavity body seat 65 is arranged correspondingly 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 channel between them. The role of the valve structure, and the valve plate 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 generate a greater pre-cap tightness 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 of the valve membrane 64 641b seals the outlet valve channel 652 of the valve cavity seat 65, and at the same time fits the convex structure 6521 of the valve cavity seat 65 to produce a preforce (Preforce) effect, which helps to produce a greater pre-closing effect, with The anti-backflow pressure chamber 657, so when the fluid delivery device 6 in this case does not operate, there will be no backflow effect between the inlet passage 631 and the outlet passage 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 suction, so that the valve plate 641a of the valve diaphragm 64 is subjected to a suction 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, and the inlet valve channel 651 of the valve cavity seat 65 flow into the pressure chamber 657 for temporary storage, and at the same time, the outlet valve channel 652 is also subjected to suction, and the valve diaphragm 64 The valve piece 641b of the valve is subjected to the suction force, and the entire valve piece 641b is flatly pressed downwards and close to the convex structure 6521 by the support of the extension bracket 642b, and presents 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 42b.
