Description

Electronic cigarette
[ technical field ] A method for producing a semiconductor device
The present disclosure relates to an electronic cigarette, and more particularly, to an electronic cigarette with a micro-pump structure.
[ 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 elements that can be assembled together and then mounted within a first housing 1A and a second housing 1B. The first and second housings 1a, 1b 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 power supply device 2, a sensor 3, an atomizer means 4 and a liquid storage means 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 arranged on the first casing 1a and is close to the area of 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 the cigarette liquid on the reservoir 52 is absorbed and permeated into the liquid permeable member 42. An air inlet connecting part 7 is arranged between the atomizing part 4 and the sensor 3 to form an air flow loop which is communicated with the channel 51 of the liquid storage part 5, so that outside 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 5. In addition, the electronic cigarette is further provided with an electrode ring 8 electrically connected to two leads of the electric heater 41, respectively, the electrode ring 8 is electrically connected to the power supply unit 2 through the connection of the air inlet and electrical connection member 10 and the sensor 3, the sensor 3 opens or closes 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 is communicated with the passage 51 of the liquid storage member 5. When a user inhales, the gas within 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 from the liquid storage container 52 to the liquid permeating part 42 through the conducting part 431 of the liquid conducting part 43, when the user inhales air from the suction nozzle 9, the air in the electronic cigarette flows, the sensor 3 opens the whole circuit according to the air flow, the power supply device 2 supplies power to the electrode ring 8 to start the electric heater 41 to heat, the cigarette liquid permeates to the liquid permeating part 42 to generate atomization through the electric heater 41, and the user can inhale the atomized smoke 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 from the conducting portion 431 of the liquid conducting member 43 to the liquid permeating member 42 has the following problems:
1. since the penetration amount cannot be precisely controlled by the conducting portion 431 of the liquid-transmitting member 43, the liquid-permeating member 42 adsorbs the cigarette liquid unevenly, so that the liquid-permeating member 42 contains a small amount of the cigarette liquid, and the liquid drops are unevenly distributed, thereby generating scorching smoke by heating with the electric heater 41, and causing the smoker to feel uncomfortable.
2. Because the conductive portion 431 of the liquid conductive member 43 cannot accurately control the amount of penetration, especially when the suction nozzle 9 is upward, the gravity force is downward to cause the cigarette liquid in the liquid storage container 52 at the periphery of the channel 51 of the liquid storage member 5 to not completely stop the amount of the liquid permeable member 42, so that when the liquid permeable member 42 is full, the cigarette liquid can drip to the air inlet and connecting member 10 and then leak out from the at least one air inlet 1c through the sensor 3, thereby causing the oil leakage problem.
In addition, there is still some gap in the feel of electronic cigarettes and real cigarettes, for example, people are accustomed to taking quick short and hard puffs when smoking cigarettes, rather than long soft puffs when electronic cigarettes and vaporizers are taken. This is because real tobacco inhales a large amount of oxygen when the user inhales quickly, which results in a faster burning and atomizing rate of the tobacco, and the user can quickly inhale the amount of smoke he wants. However, the electronic cigarette cannot adjust the power supply to the electric heater and the heating speed when smoking, if the heating speed is too high, the tobacco tar in the atomizer is atomized too fast, and the liquid supply of the electronic cigarette is too slow due to the siphon phenomenon, and finally the problems of insufficient smoke evaporated by the atomizer or burnout of the atomizer are caused. The power supply to the atomizer of a conventional electronic cigarette is constant, and the user must take a gentle puff for the atomizer to heat up enough time to atomize the tobacco tar.
In view of the above, how to develop an electronic cigarette that can improve the above-mentioned technical deficiencies of the known electronic cigarette and replace the actual cigarette is a problem that needs to be solved urgently.
[ summary of the invention ]
The main objective of the present invention is to provide an electronic cigarette, which is mainly formed by combining a fluid control device with a liquid guide tube of an atomizing component to form a controllable switch to precisely control the amount of liquid permeating the atomizing component of the cigarette, so as to solve the problems of uneven smoke taste and oil leakage caused by liquid drops in the conventional electronic cigarette technology.
Another objective of the present invention is to provide an electronic cigarette, which mainly includes a sensor including an airflow sensor and an air pressure sensor, wherein the sensor monitors the pressure of the airflow passing through the electronic cigarette according to the suction pressure of the user, outputs an adjustment signal to adjust the control signal of the control module, and adjusts the driving frequency of the fluid delivery device and the driving power of the heater module to change the speed of atomizing the tobacco tar and the speed of supplying the liquid, so that the user can quickly inhale a large amount of smoke, and can keep the same amount of smoke in each bite when the user is going to bite.

Referring to fig. 5A and 5B, the actuator 66 is assembled by a vibrating plate 661 and a piezoelectric element 662, wherein the piezoelectric element 662 is attached and fixed on a surface of the vibrating plate 661. In the present embodiment, the vibrating plate 661 is made of metal, and the piezoelectric element 662 is made of piezoelectric powder of lead zirconate titanate (PZT) series with high piezoelectric number, and is attached to the vibrating plate 661, so that the piezoelectric element 662 is driven to deform by applying a voltage, and the vibrating plate 661 is driven to vibrate and deform in a vertical reciprocating manner along with the applied voltage, so as to drive the fluid conveying device 6 to operate.

As is apparent from the above description, the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 constitute the main structure of the fluid transport device 6 for guiding the transport fluid in and out. However, the main subject of the present invention is how to position the stacked and combined structure, and the locking and positioning assembly without using locking elements (such as screws, nuts, bolts, etc.). Therefore, the valve body 63, the valve diaphragm 64, the valve chamber seat 65, and the actuator 66 are sequentially stacked inside the outer cylinder 67 by using the design of the valve cover 62 and the outer cylinder 67, and the valve cover 62 is directly fitted inside the outer cylinder 67 to be positioned and assembled.
Referring to fig. 5A, 5B and 9, the outer tube 67 is made of metal, and has an inner wall 671 surrounding a hollow space, and a bottom of the inner wall 671 of the outer tube 67 has a protruding ring structure 672.
