Description

electronic cigarette

【Technical field】

This case is about an electronic cigarette, especially an electronic cigarette with a micro-pump structure.

【Background technique】

The use of electronic cigarettes, or so-called electronic cigarettes, is rapidly expanding as an alternative to traditional cigarettes that smoke real tobacco. As shown in Figures 1A and 1B, the electronic cigarette includes components that can be assembled together and then mounted within a first housing 1a and a second housing 1b. The first casing 1a and the second casing 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 part 4 and Liquid storage part 5. The power supply device 2 and the sensor 3 are installed in the first casing 1a, and the first casing 1a is provided with at least one area of the air inlet 1C close to 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 set on the electric heater 41. The permeating part 42 and a liquid conducting part 43 closely matched with the liquid permeating part 42, the electric heater 41 is a hollow structure; and the liquid storage part 5 is installed in the second casing 1b, and has a passage 51 through which the gas flows. , and there is a liquid storage container 52 on the periphery of the channel 51, and the liquid conduction member 43 is sleeved on the liquid permeable member 42, and the conducting part 431 of the liquid conduction member 43 is in contact with the liquid storage container 52. Therefore, the cigarette on the liquid storage container 52 The liquid is absorbed and penetrated into the liquid permeation member 42 . Between the atomizing part 4 and the sensor 3, an air inlet connecting part 7 is arranged to form an air flow circuit for communicating with the channel 51 of the liquid storage part 5, so that the outside air can enter through the sensor 3 through at least one air inlet 1c and then be electrically heated. The container 41 is introduced into the channel 51 of the liquid storage member 5 . In addition, the element of the electronic cigarette is further provided with an electrode ring 8, which is electrically connected to the two leads 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 whole circuit according to the airflow, and finally the suction nozzle 9 is assembled at one end of the second housing 1b, and the channel 51 of the liquid storage part 5. When the user inhales, the gas inside the electronic cigarette flows. At this time, the sensor 3 is turned on, and the electric heater 41 is activated 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 penetrated from the liquid storage container 52 through the conducting part 431 of the liquid conducting member 43 to the liquid permeating member 42. When the user inhales air through the mouthpiece 9, the gas in the electronic cigarette flows, and the sensor 3 opens the entire electronic cigarette according to the air flow. The 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 permeation part 42 and is atomized by 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 is penetrated by the conducting portion 431 of the liquid conducting member 43 into the design of the liquid permeating member 42, and there will be the following problems:

1. Because the conducting part 431 of the liquid conducting member 43 cannot precisely control the penetration amount, the liquid penetration member 42 absorbs the cigarette liquid unevenly, resulting in the liquid penetration member 42 containing the part with a small amount of cigarette liquid, resulting in uneven droplets. , which is heated by the electric heater 41 to produce burnt smoke, and the smoker will feel uncomfortable in the mouthfeel.

2. Because the conducting part 431 of the liquid conducting part 43 cannot precisely control the amount of penetration, especially when the suction nozzle 9 is facing upwards, the cigarette liquid in the liquid storage container 52 around the channel 51 of the liquid storage part 5 cannot be completely controlled due to the downward gravity. The amount of the permeable liquid permeating member 42 is stopped, so that when the permeating liquid permeating member 42 is full, the cigarette liquid will drip to the air inlet and the connecting member 10 and then leak out from the at least one air inlet 1c after passing through the sensor 3, causing the problem of oil leakage .

In addition, there are still some differences in the feeling of e-cigarettes and real cigarettes. For example, when people smoke, they are used to taking quick, short and hard puffs, rather than taking long and gentle puffs in e-cigarettes and vaporizers. This is because the real smoke will inhale a lot 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, there is no way for electronic cigarettes to change and adjust the power supply and heating speed transmitted to the electric heater when smoking. If the heating is too fast, it will cause the e-liquid in the atomizer to be atomized too quickly, and as the above-mentioned known electronic cigarettes The liquid supply by the power of the siphon phenomenon will be too slow, which will eventually lead to problems such as insufficient vaporization of the atomizer or burnout of the atomizer. Therefore, the power delivered by the general electronic cigarette to the atomizer 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, there are currently existing atomized electronic cigarettes. There are still many problems and drawbacks that lead to significant differences between real cigarettes and smokers' electronic cigarettes, which discourage smokers from choosing electronic cigarettes instead of real cigarettes.

In view of this, how to develop an electronic cigarette that can improve the above-mentioned deficiencies in the known electronic cigarette technology and develop an electronic cigarette that replaces the real cigarette is a problem that needs to be solved urgently at present.

In this embodiment, the vibrating plate 661 is made of metal material, and the piezoelectric element 662 can be made of piezoelectric powder of lead zirconate titanate (PZT) series with high voltage, so as to be attached and fixed on the vibrating plate 661 . A voltage is applied to drive the piezoelectric element 662 to generate deformation, so that the vibration plate 661 also generates a vertical reciprocating vibration deformation, which is used to drive the action of the fluid conveying device 6 . The vibration plate 661 of the actuator 66 is assembled on the fourth surface 656 of the valve cavity seat 65 to cover the pressure chamber 657 , and the fourth surface 656 is located in the step groove 658 outside the pressure chamber 657 for a A sealing ring 68e is nested therein to prevent fluid leakage around the pressure chamber 657 .

As can be seen from the above description, the valve body 63 , the valve diaphragm 64 , the valve cavity seat 65 , and the actuator 66 may constitute the main structure for the introduction and exit of the fluid conveying device 6 . However, how to position the stacked and combined structure without using locking elements (eg, screws, nuts, bolts, etc.) to lock and assemble for positioning is the main subject of the present invention. Therefore, the design of the valve cover body 62 and the outer cylinder 67 is adopted below. The valve body 63, the valve diaphragm 64, the valve cavity seat 65, and the actuator 66 are sequentially stacked inside the outer cylinder 67, and then the valve cover body is used. 62 is directly and tightly fitted to the interior of the outer cylinder 67 to be positioned and assembled for illustration.

Please refer to FIGS. 5A , 5B and 9 , the outer cylinder 67 is made of metal, with an inner wall 671 surrounding a hollow space, and the bottom of the inner wall 671 of the outer cylinder 67 has a convex ring structure 672 . Please refer to FIG. 10A and FIG. 10B again, the valve cover body 62 is also made of a metal material, and has a first through hole 621 and a second through hole 622 , which are respectively used for the inlet channel 631 and the outlet channel 632 of the valve body 63 . The corresponding 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 size of 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 seat 65 , and the actuator 66 are stacked in sequence and then placed in the inner wall 671 of the outer cylinder 67 , so that the entire stacked structure can carry the load. 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 size of 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 tightly fit each other. The positioning valve body 63 , the valve diaphragm 64 , the valve cavity seat 65 , and the actuator 66 are stacked in sequence to form the fluid delivery device 6 , and the actuator 66 can also be located in the hollow space of the inner wall 671 of the outer cylinder 67 . The piezoelectric element 662 is subjected to an applied voltage to drive the vibrating plate 661 to perform vertical reciprocating motion to deform and resonate, so as to achieve a fluid delivery device 6 that does not require locking elements (eg, screws, nuts, bolts, etc.) to lock and assemble.

As shown in FIG. 11 , in the fluid delivery device 6 constructed in this case, the inlet valve channel 651 of the valve cavity seat 65 is arranged corresponding to the inlet opening 6311 of the valve body 63 , and is closed by the valve sheet 641 a of the valve diaphragm 64 therebetween. It acts as a valve 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 effect, which helps to generate a larger pre-cover Tightening effect to prevent reverse flow, and the outlet valve channel 652 is arranged corresponding to the outlet opening 6321 of the valve body 63, and the valve sheet 641b of the valve diaphragm 64 is used to seal the valve structure, and the valve of the valve diaphragm 64 is closed. The sheet 641b covers 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 generate a preforce effect, which is helpful to produce a greater pre-tightening effect. In order to prevent backflow to the pressure chamber 657 , when the fluid conveying device 6 constructed in this case does not act, there will be no backflow effect between the inlet passage 631 and the outlet passage 632 of the valve body 63 .

It can be seen from the above description that the fluid conveying device 6 of the present case is implementing the operation of fluid transmission. As shown in FIG. 12A, when the piezoelectric element 662 of the actuator 66 is actuated by the applied voltage, the vibration plate 661 is deformed concavely. The volume of the pressure chamber 657 will increase when the pressure chamber 657 increases, thereby generating suction, so that the valve sheet 641a of the valve diaphragm 64 is subjected to a suction force to open rapidly, so that a large amount of fluid can be sucked in from the inlet channel 631 on the valve body 63 and flow through The inlet opening 6311 of the valve 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, while the outlet valve channel 652 is also subjected to suction, and the valve diaphragm The valve sheet 641b of 64 is affected by the suction force, and is supported by the extension bracket 642b, so that the entire downwardly and flatly abuts against the protruding 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 vibration plate 661 upward, and the pressure chamber 657 shrinks and the volume decreases, so that the pressure chamber 657 shrinks. The fluid in the chamber 657 is squeezed, and at the same time, the inlet valve channel 651 is thrust, and the valve sheet 641a of the valve diaphragm 64 is affected by this thrust, and is supported by the extension bracket 642a to produce the entire upward flat against the convex structure. 6343 is in a closed state, the fluid cannot flow backward from the inlet valve channel 651, and at this time, the outlet valve channel 652 is also thrust, and the valve plate 641b of the valve diaphragm 64 is affected by this thrust, and is supported by the extension bracket 42b. The fluid can flow out of the pressure chamber 657 through the outlet valve channel 652, through the outlet valve channel 652 of the valve chamber seat 65, and the valve diaphragm 64.
