Description

electronic cigarette

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

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 Figs. 1A and 1B, the electronic cigarette includes elements that can be assembled together and then mounted in the first casing 1a and the second casing 1b. The first casing 1a and the second casing 1b may be a thin-walled metal pipe, such as stainless steel, having a length and a diameter similar to those of a conventional tobacco cigarette, and the components of the electronic cigarette include a power supply device 2, a sensor 3, an atomizing member 4, and Liquid storage unit 5. The power supply device 2 and the sensor 3 are mounted in the first housing 1a, and the first housing 1a is provided with an area where at least one air inlet 1c is close to the sensor 3. The atomizing member 4 and the liquid storage member 5 are mounted in the second casing 1b, and the atomizing member 4 is fixedly supported by a bracket 7 including the electric heater 41 and the liquid set on the electric heater 41. The permeable member 42 and a liquid conducting member 43 closely engaged with the liquid permeable member 42, the electric heater 41 is a hollow structure; and the liquid storing member 5 is mounted in the second housing 1b, having a passage 51 through which the gas flows inside. And having a liquid storage container 52 on the periphery of the passage 51, and the liquid conductive member 43 is fitted over the liquid permeating member 42, and the conductive portion 431 of the liquid conductive member 43 is in contact with the liquid storage container 52, and therefore, the cigarette liquid on the liquid storage container 52 It is absorbed and infiltrated into the liquid permeating member 42. Further, an air inlet connecting member 7 is disposed between the atomizing member 4 and the sensor 3 to form an air flow circuit for communicating with the passage 51 of the liquid storage member 5, so that the outside air can enter the passing sensor 3 through the at least one air inlet 1c. The heater 5 is introduced into the passage 51 of the liquid storage member 5. In addition, the components of the electronic cigarette are further provided with an electrode ring 8 electrically connected to the two leads of the electric heater 41, and the electrode ring 8 is electrically connected to the power supply device 2 through the connection of the intake and electrical connection members 10 and the sensor 3, and the sensor 3 The entire circuit is opened or closed according to the air flow, and the last nozzle 9 is assembled at one end of the second casing 1b to communicate with the passage 51 of the liquid storage member 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 to perform heating. When the user stops inhaling, the gas stops flowing, and the sensor 3 turns off the circuit to stop the electric heater 41 from heating. Thus, the cigarette liquid is permeated from the liquid storage container 52 through the conduction portion 431 of the liquid conductive member 43 to the liquid permeating member 42, and when the user inhales the air by the suction nozzle 9, the gas in the electronic cigarette flows, and the sensor 3 opens the entire circuit according to the air flow. The power supply device 2 supplies power to the electrode ring 8 to activate the electric heater 41 for heating, and the cigarette liquid permeates into the liquid permeating member 42 to be atomized by the electric heater 41, and the user can suck the liquid storage member 5 from the suction nozzle 9. The atomizing smoke of the passage 51.

The cigarette liquid of the above electronic cigarette is infiltrated into the liquid permeating member 42 by the conduction portion 431 of the liquid conducting member 43, and has the following problems:

1. Since the conduction portion 431 of the liquid conductive member 43 cannot accurately control the amount of permeation, the phenomenon that the liquid permeating member 42 adsorbs the unevenness of the cigarette liquid is caused, and the liquid permeating member 42 contains a portion having a small amount of the cigarette liquid, resulting in uneven droplets. When the electric heater 41 is heated to generate burnt smoke, the smoker may feel uncomfortable.

2. Since the conduction portion 431 of the liquid conductive member 43 cannot accurately control the amount of permeation, especially when the suction nozzle 9 faces upward, the gravity of the cigarette liquid in the liquid storage container 52 around the passage 51 of the liquid storage member 5 cannot be completely stopped. When the amount of the permeated liquid permeating member 42 is caused to cause the permeated liquid permeating member 42 to be full, the cigarette liquid is dripped to the intake and connecting member 10 and leaked through the sensor 3 through at least one of the intake ports 1c, causing oil leakage problems.

In addition, there are still some gaps between e-cigarettes and real cigarettes. For example, when people smoke, they will get used to taking short and hard sucks instead of taking long-term gentle sucking in e-cigarettes and evaporators. This is because the real smoke inhales a large amount of oxygen when the user inhales quickly, causing the tobacco to burn and atomize faster, and the user can quickly absorb the amount of smoke he wants. However, there is no way for electronic cigarettes to change the speed of the power and heating sent to the electric heater when smoking. If the heating is too fast, the smoke in the atomizer will be atomized too fast, as in the above-mentioned electronic cigarettes. The power supplied by the siphon phenomenon will be too slow, and finally the problem of insufficient amount of smoke evaporated by the atomizer or burnout of the atomizer. Therefore, the power supply of the general electronic cigarette to the atomizer is constant, and the user must have a long and gentle suction to allow the atomizer to have sufficient time to heat and atomize the oil, so that the current atomized electronic cigarette is still There are a number of problems and shortcomings that cause significant differences between real cigarettes and smokers' 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 conventional electronic cigarette technology and develop an electronic cigarette instead of a real cigarette is an urgent problem to be solved.

The main purpose of the present invention is to provide an electronic cigarette, which is mainly provided by a fluid control device combined with a liquid guiding tube of an atomizing component to form a controllable switch for accurately controlling the amount of the infiltrating atomizing component of the cigarette liquid, and solving the problem of the conventional electronic cigarette technology. The droplets produce uneven smoke with poor mouthfeel and oil leakage problems.

Another object of the present invention is to provide an electronic cigarette, mainly for enabling an electronic cigarette user to quickly absorb a large amount of smoke, thereby providing a sensor including an air flow sensor and an air pressure sensor, according to the user's suction pressure.

As can be seen from the above description, the valve body 63, the valve diaphragm 64, the valve body seat 65, and the actuator 66 can constitute the main structure in which the fluid guiding device of the fluid transport device 6 is introduced. However, how to position such a stacked structure and to lock the positioning assembly without locking components (for example, screws, nuts, bolts, etc.) is a main subject to be implemented by the present invention. Therefore, the valve body 63, the valve diaphragm 64, the valve body seat 65, and the actuator 66 are sequentially laminated inside the outer cylinder 67, and then the valve cover is used. The description is made by directly fitting and fitting the inner portion of the outer cylinder 67 to the outer cylinder 67.

Referring to FIGS. 5A, 5B, and 9 , the outer tube 67 is made of a metal material having an inner wall 671 surrounding a hollow space, and the inner wall 671 of the outer tube 67 has a convex ring structure 672 at the bottom. Referring to FIG. 10A and FIG. 10B , 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 respectively for the inlet passage 631 and the outlet passage of the valve body 63 . The 632 is correspondingly 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, as shown in FIGS. 5A and 5B, the valve body 63, the valve diaphragm 64, the valve 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 whole The laminated structure is carried on the convex ring structure 672 of the outer cylinder 67, and the valve cover body 62 is designed to have a smaller outer diameter than the inner wall 671 of the outer cylinder 67, and can be smoothly introduced into the inner wall 671 of the outer cylinder 67 by using the chamfer 623. And the fluidizing device 6 is formed in series with the positioning valve body 63, the valve diaphragm 64, the valve body seat 65, and the actuator 66, and the actuator 66 is also within the outer tube 67. In the hollow space of the wall 671, the piezoelectric element 662 is subjected to a voltage to drive the vibrating plate 661 to perform a vertical reciprocating motion to form a resonance, thereby achieving a fluid that does not need to be locked by a locking component (for example, a screw, a nut, a bolt, etc.). Conveying device 6.

As shown in Fig. 11, in the fluid transport device 6 of the present invention, the inlet valve passage 651 of the valve body seat 65 is disposed corresponding to the inlet opening 6311 of the valve body 63, and is closed by the valve piece 641a of the valve diaphragm 64. The function of the valve structure is performed, and the valve piece 641a covers the inlet opening 6311 of the valve body 63, and at the same time, the convex portion structure 6343 of the valve body 63 is attached to generate a pre-force effect, which helps to produce a larger pre-cover. The tightening effect is to prevent backflow, and the outlet valve passage 652 is disposed corresponding to the outlet opening 6321 of the valve body 63, and is closed by the valve piece 641b of the valve diaphragm 64 to function as a valve structure, and the valve of the valve diaphragm 64 The piece 641b covers the outlet valve passage 652 of the valve cavity seat 65, and simultaneously engages the convex portion structure 6521 of the valve cavity seat 65 to generate a pre-force effect, which contributes to a larger pre-tightening effect. In order to prevent the backflow pressure chamber 657, the fluid transport device 6 constructed in the present case does not generate a backflow between the inlet passage 631 and the outlet passage 632 of the valve body 63 without being actuated.

As can be seen from the above description, the fluid transporting device 6 of the present invention performs the fluid transporting operation as shown in FIG. 12A. When the piezoelectric element 662 of the actuator 66 is actuated by the application of a voltage, the vibrating plate 661 is concavely deformed. When the volume of the pressure chamber 657 is increased, suction is generated, and the valve piece 641a of the valve diaphragm 64 is quickly opened by a suction force, so that the fluid can be sucked in a large amount from the inlet passage 631 on the valve body 63, and flows through The inlet opening 6311 of the valve body 63, the hollow hole 643a of the valve diaphragm 64, the inlet valve passage 651 of the valve cavity seat 65 flow into the pressure chamber 657, and the suction valve passage 652 is also subjected to suction, the valve diaphragm The valve piece 641b of 64 is subjected to this suction force, and the entire downward flat contact against the convex portion structure 6521 is brought into a closed state by the support of the extension bracket 642b.

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 cause the vibration plate 661 to be convexly deformed, and at this time, the pressure chamber 657 contracts and the volume is reduced to make the pressure chamber. The fluid in the chamber 657 is squeezed, and at the same time, the inlet valve passage 651 is subjected to the thrust, and the valve piece 641a of the valve diaphragm 64 is subjected to the thrust, and the support is extended by the extension bracket 642a to produce the entire upward flatness against the convex structure. 6343 is in a closed state, the fluid cannot be reversed by the inlet valve passage 651, and at this time, the outlet valve passage 652 is also subjected to thrust, and the valve piece 641b of the valve diaphragm 64 is subjected to the thrust, and the entire support is generated by the support of the extension bracket 42b. The detachment is in a state of being close to the convex portion structure 6521, and the fluid is discharged from the outlet valve passage 652 out of the pressure chamber 657 via the outlet valve passage 652 of the valve cavity seat 65 and the valve diaphragm 64. The hollow hole 643b, the outlet opening 6321 on the valve body 63, and the outlet passage 632 flow out of the fluid delivery device 6, so that the process of fluid transfer is completed, and the operations of FIGS. 12A and 12B are repeated, that is, sustainable A fluid delivery line, thus using the fluid delivery device 6 in this case allow fluid to the transfer process does not produce reflux case, to achieve high transmission efficiency.

The fluid delivery device 6 is assembled between the sensor 3 and the atomizing component 4, the inlet channel 631 of the fluid delivery device 6 communicates with the input channel 6a to the reservoir container 52, and the outlet channel 632 of the fluid delivery device 6 communicates with the output channel 6b, the output The passage 6b communicates with the liquid permeating member 42 of the atomizing member 4, so that the cigarette liquid can be transported by the fluid delivery device 6 into the liquid permeating member 42. Therefore, when the fluid delivery device 6 is driven by the control module 22 to provide voltage control, the cigarette liquid is quantitatively delivered by the liquid storage container 52, and as a switch, the cigarette liquid in the liquid storage container 52 can be controlled to be supplied to the cigarette liquid. The quantitative output is introduced into the liquid permeating member 42 to uniformly permeate the liquid permeating member 42 at the same pressure to produce uniformity of the liquid droplets, and to control the closed transport when the liquid permeating member 42 is full. The control device 6 is combined with the arrangement of the atomizing member 4 to form a controllable switch for accurately controlling the amount of the permeated liquid permeating member 42 of the cigarette liquid, which solves the problem of poor uniformity of the smoke generated by the droplets of the conventional electronic cigarette technology and the problem of oil leakage.

Referring to FIG. 2A and FIG. 2C, the suction nozzle 9 is assembled at one end of the second casing 1b and communicates with the passage 51 of the liquid storage member 5, and the suction nozzle 9 has a filter 91 and an opening 92. The filter cotton 91 is placed at the end of the passage 51 of the liquid storage member 5, so that the initial heated atomization of the incomplete cigarette liquid is blocked by the filter 91 to form a filter protection against inhalation.

As can be seen from the above, the specific implementation of the electronic cigarette of the present invention is as follows.
