Detailed ways

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

This embodiment discloses an electronic cigarette, which can be a disposable electronic cigarette or an electronic cigarette that can be refilled with oil. The electronic cigarette includes a control system, and the control system is used to control the overall working process of the electronic cigarette.

Please refer to FIG. 1 , the control system includes a pneumatic switch device, an atomization module 90 , a control module and a power supply module 80 . The power supply module 80, the atomization module 90 and the pneumatic switch device are respectively electrically connected to the control module. The control module may include a chip board 70, and the chip board 70 may be a chip board 70 commonly used in electronic cigarettes on the market, and the specific model of the chip board 70 is not limited herein. The pneumatic switching device can be electrically connected to the chip board 70 through wires.

The atomizing module 90 may include an atomizing core, the atomizing core includes a heating element, and the heating element may be a heating wire or a ceramic heating tube or other heating components, and the conductive pins of the heating element are conductively connected to the chip board 70 through wires, or the heating element The conductive pins of the electronic cigarette are directly conductively connected to the chip board 70; the e-liquid in the e-liquid tank is guided to the heating element through the oil-guiding cotton, so that the e-liquid is atomized by the atomizing core.

The power supply module 80 is used to supply power to the atomization module 90, the control module and the pneumatic switch device; specifically, the power supply module 80 may include a rechargeable and reusable battery, the two poles of the battery are connected to the chip board 70 through wires, and the battery passes through the chip board. 70 supplies power to the atomization module 90 and the pneumatic switching device.

In one application scenario, the pneumatic switch device is arranged on the airflow trajectory of the electronic cigarette. When the user inhales the electronic cigarette, an air flow is generated in the electronic cigarette, and the airflow causes the working state of the pneumatic switch device to change. The working state of the switch device is changed to control the atomization module 90 to start atomizing e-liquid or stop atomizing e-liquid.

In the prior art, the pneumatic switch of the electronic cigarette is generally a capacitive microphone head. The capacitive microphone head includes electrode plates 20 and conductive films arranged at intervals and opposite to each other. When the user inhales the electronic cigarette, the airflow enters the electronic cigarette and drives the electronic cigarette. The conductive film deforms the conductive film, which causes the distance between the conductive film and the electrode plate 20 to change, thereby causing the equivalent capacitance to change. The capacitive microphone switch feeds back the capacitance change signal to the control board of the electronic cigarette. When the capacitance changes When the amount of change reaches a certain level, the control board controls the atomizer of the electronic cigarette to start atomizing the e-liquid. Since the deformation of the conductive film is easily affected by external factors, for example, when the temperature is high, the conductive film is easily deformed, which will cause the working state of the capacitive microphone switch to be unstable, and even a small airflow will cause the conductive film to deform. , so that the atomizer of the electronic cigarette is easy to start automatically when the electronic cigarette is not in use. This phenomenon is more likely to occur when the resistance value of the heating element is small, especially the heating element with a resistance value below 0.7 ohms. The larger the temperature, the higher the temperature in the electronic cigarette, and the more prone to deformation of the conductive film. In addition to the influence of temperature on the deformation of the conductive film, during the assembly process of the capacitive microphone, the conductive film is easily touched and deformed, which will cause the shape of the conductive film to change after the capacitive microphone is assembled. , which will affect the working sensitivity of the subsequent capacitive microphones, thereby affecting the working stability of the capacitive microphones. To sum up, the capacitive microphone in the prior art mainly changes the working state through the deformation of the conductive film. Since the deformation of the conductive film is easily disturbed by external factors, the capacitive microphone is prone to malfunction. stable phenomenon.

The deformation portion 42 is pressed to move the deformation portion 42 toward the second space 13 .

Further, one end of the housing 10 is open and the other end is closed. The electrode plate 20 is arranged at the open end of the casing 10 , specifically, the electrode plate 20 is arranged in the open end of the casing 10 , and the edge contour shape of the electrode plate 20 is adapted to the shape of the port of the open end of the casing 10 , when the electrode plate 20 is arranged in the open end of the casing 10, the circumferential side wall of the electrode plate 20 abuts the open end of the casing 10, thereby closing the end. Since the electrode plate 20 is arranged in the casing 10 , which can reduce the probability that the electrode plate 20 is touched and dropped, and also can make the appearance of the casing 10 cleaner. The first space 12 is located between the electrode plate 20 and the aerodynamic deformation member 40. In order to make the air in the first space 12 circulate with the outside air, the electrode plate 20 is provided with two first air holes 21 for air circulation. In other embodiments, the number of the first air holes 21 may be one or more. The second space 13 is located between the end wall of the closed end of the casing 10 and the aerodynamic deformation member 40.

Next, the mechanism of the pneumatic deformation member 40 of this embodiment will be further described.

The pneumatic deformation member 40 includes an annular base 41 , and the shape and size of the annular base 41 are adapted to the interior of the casing 10 . When the annular base 41 is arranged inside the casing 10 , the annular base 41 The outer peripheral side wall of the casing 10 is abutted against the inner wall of the casing 10. Preferably, the annular base 41 can be a silicone base or other soft material base with good elasticity. The annular base 41 has a certain elasticity, so that the annular base 41 can be closely abutted with the inner wall of the housing 10, which can improve the air tightness on the one hand, and improve the firmness of the annular base 41 on the other hand. Confined inside the housing 10 . The deformation portion 42 is a deformation layer extending radially along the annular base 41 and connected to the edge of the annular base 41. Specifically, the deformation layer is a silica gel film, and the deformation layer and the annular base 41 are integrally formed, so that this embodiment can be The pneumatic deformation member 40 of the example is relatively simple in structure and easy to manufacture.

Next, the structures and installation methods of the first magnetically attracting conductive component 30 and the second magnetically attracting conductive component 50 in this embodiment will be further described.

In this embodiment, the first magnetically attractive conductive component 30 includes a positive magnetically attractive terminal 31 and a negative magnetically attractive terminal 32 that can be magnetically attracted to the second magnetically attractive conductive component 50 . The conductive connection is achieved by the second magnetically attractive conductive component 50 . Specifically, the positive magnetic terminal 31 and the negative magnetic terminal 32 are both half-moon shaped, and the positive magnetic terminal 31 and the negative magnetic terminal 32 are symmetrically and spaced apart on the side of the electrode plate 20 facing the deformation portion 42 , wherein, The positive magnetic attraction terminal 31 and the negative magnetic attraction terminal 32 are both conductive magnets, such as neodymium iron boron magnets, samarium cobalt magnets, alnico magnets, iron chrome cobalt magnets, and the like. In other embodiments, the positive magnetic terminal 31 may be composed of a magnet and a conductive member, the magnet is used for magnetically attracting the second magnetically conductive member 50 , and the conductive member is used for abutting and conductive connection with the second magnetically attracting conductive member 50 The structure of the negative magnetic terminal 32 is also the same. Of course, in another embodiment, one of the positive magnetic terminal 31 and the negative magnetic terminal 32 is provided with a magnet to magnetically attract the second magnetic conductive component 50 ie Can.

Further, in this embodiment, the positive magnetic terminal 31 and the negative magnetic terminal 32 are both conductively connected to the working circuit 60 on the electrode plate 20. When the positive magnetic terminal 31 and the negative magnetic terminal 32 are magnetically attracted to the second When magnetically attracting the conductive assembly 50 , the working circuit 60 is open, and when the positive magnetically attracting terminal 31 and the negative magnetically attracting terminal 32 are separated from the second magnetically attracting conductive assembly 50 , the working circuit 60 is disconnected. The working circuit 60 is conductively connected to the chip board 70 of the control module through wires. When the working circuit 60 is connected, the working circuit 60 has current passing through, and the chip board 70 receives the corresponding signal that the working circuit 60 has current passing through. At this time, the chip The plate 70 stops supplying current to the heating element of the atomizing core, so that the heating element can be stopped from heating, and the electronic cigarette is in a stop working state at this time. When the electronic cigarette is inhaled, the airflow flowing through the inside of the electronic cigarette causes an air pressure difference between the first space 12 and the second space 13, so that the negative pressure drives the deformation part 42 away from the electrode plate 20, and the deformation part 42 drives the second space 13. The magnetic conductive assembly 50 is separated from the positive magnetic terminal 31 and the negative magnetic terminal 32. At this time, the working circuit 60 is disconnected, and no current flows through the working circuit 60. At this time, the chip board 70 of the control module receives no current from the working circuit 60. The chip board 70 controls the heating element to start heating the e-liquid according to the signal corresponding to the passing of the current.

Among them, due to the gravity of the magnetic sheet 51 and the magnetic attraction force between the magnetic sheet 51 and the first magnetically attractive conductive component 30 to pull the deformation layer, the deformation layer will be deformed to a certain extent. Therefore, the deformation layer presents a concave shape as shown in the figure. .

In other embodiments, the plug-in block 52 has a columnar structure extending axially along the magnetic sheet 51, such as a cylindrical structure, a prismatic structure, etc., and an annular groove surrounding the axis of the plug-in block 52 is formed on the side wall of the plug-in block 52; The deformation layer is provided with an insertion hole 421 for the insertion block 52 to be inserted; when the insertion block 52 is inserted into the insertion hole 421, the edge of the insertion hole 421 is located in the annular groove, under the limit of the annular groove , the plug-in block 52 will not be easily separated from the plug-in hole 421 , thereby improving the connection reliability between the magnetic suction sheet 51 and the deformation layer.
