[0002] Electronic cigarettes are electronic products that imitate cigarettes, with the same appearance, smoke, taste and feel as cigarettes. They are mainly used to quit smoking and replace cigarettes. They have the same appearance and similar taste as cigarettes, but they do not contain tar, suspended particles and other harmful components in cigarettes.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] The following is combined with Figure 1-7 The present invention is further described with examples:

[0030] In this embodiment, refer to Figure 1-5 As shown, an electronic cigarette using a PCB special guide groove silicon microphone comprises a cigarette rod sleeve 1 and a smoke generator 2. The smoke generator 2 is detachably buckled and connected to the cigarette rod sleeve 1. A placement cavity 10 is provided in the cigarette rod sleeve 1. An air inlet 101 is provided on one side of the placement cavity 10. An adjustment module 3 is provided in the placement cavity 10. A shell 13 is provided in the placement cavity 10. A power supply module is provided on one side of the shell 13 and a smoke generator 2 is provided on the other side. A control module is provided in the shell 13. When in use, an operator can inhale the smoke generator 2, and then the outside air is inhaled from the air inlet 101, passing through the shell After the control module in the body 13 is installed, the control module senses the airflow passing through and controls the power supply module to supply power to the smoke generator 2, so that the smoke is inhaled by the user. In this process, the user can adjust the adjustment module 3 according to his own situation to change the amount of use and adjust the damping feeling during inhalation, so as to enhance the user's experience. Further, after use, the connection channel between the smoke generator 2 and the cigarette rod sleeve 1 can be blocked by controlling the adjustment module 3 to prevent the smoke oil from volatilizing into the interior of the cigarette rod sleeve 1 and prevent the smoke oil in the smoke generator 2 from flowing out.

[0031] The control module includes an airflow sensing chamber 130 arranged in a shell 13, an inflow hole 1301 is opened on one side of the airflow sensing chamber 130, and an air outflow hole 1302 is opened on the other side. A step 131 is arranged in the airflow sensing chamber 130, and a circuit board 133 is embedded in the step 131. A silicon wheat airflow sensor is arranged on the circuit board 133. The silicon wheat airflow sensor includes two connecting blocks fixedly arranged on the circuit board 133, a back plate 136, a diaphragm 137 and a MENS chip 135 are arranged between the two connecting blocks, a plurality of reserved holes 1360 are arranged on the back plate 136, a condensation pipe groove is arranged in the airflow sensing chamber 130, and after the condensation pipe groove is subjected to suction, the back plate 136 and the diaphragm 137 are connected to the condensation pipe groove. The membrane 137 is close to each other, so that the power supply module supplies power to the smoke generator 2. After the outside air enters the condensation duct from the air inlet 101 through the inflow hole 1301, and then passes through the back plate 136 and the diaphragm 137, the back plate 136 and the diaphragm 137 are close to each other, and at this time, the power supply module supplies power to the smoke generator 2 to generate smoke. During this process, when the user inhales the smoke, the smoke generator 2 and the airflow sensing chamber 130 are connected. During this process, the smoke is very easy to evaporate into the airflow sensing chamber 130 and is adsorbed in the airflow sensing chamber 130. By setting the condensation duct, the smoke oil in the smoke stays in the condensation duct, reducing the smoke oil from evaporating to the components on the upper surface of the circuit board 133 and causing damage to the components on the circuit board 133.

[0032] First of all, it should be noted that the electronic cigarette in the prior art cannot control the amount of smoke inhaled, and a large amount of smoke oil easily remains on the components on the surface of the circuit board inside the electronic cigarette, and after use, the connection channel between the smoke oil and the internal components of the electronic cigarette cannot be blocked in time.

[0033] The present invention provides an adjustment module 3 so that when the present invention is used, the smoke oil and the control module can be connected, and this connection channel is blocked after use, thereby reducing the volatilization of the smoke oil and entering the components on the upper surface of the circuit board 133. The amount of smoke inhaled can be adjusted during use, and the provision of a condenser can effectively reduce the smoke oil from entering the components on the upper surface of the circuit board 133.

[0034] In an optional embodiment, referring to Figure 3 and Figure 7As shown, the condensation pipe groove includes a condensation pipe 134 opened in the circuit board 133, and the condensation pipe 134 runs through the circuit board 133. Preferably, the condensation pipe 134 is a special guide groove design, and the condensation pipe 134 includes a connecting portion and an extension portion. The connecting portion is used to allow the inhaled gas to pass through the connecting portion from the inflow hole 1301 and then pass through the back plate 136 and the diaphragm 137, so that the back plate 136 and the diaphragm 137 are close to each other, and the extension portion is used to extend the length of the pipe to enhance the condensation effect of the airflow, so that after the smoke oil and the airflow sensing chamber 130 are connected, the smoke is condensed into smoke oil in the condensation pipe 134, thereby reducing the residue of smoke on the components on the circuit board.

[0035] In a preferred embodiment, referring to Figure 3 As shown, the condenser groove includes a placement hole 1310 symmetrically arranged in the step 131, and each placement hole 1310 is provided with a T-shaped condenser 132. After the airflow flows into the inlet hole 1301 and flows out of the airflow sensing cavity 130 through the T-shaped condenser 132, the outlet of the T-shaped condenser 132 is preferably on the upper side of the back plate 136. Therefore, when the airflow flows out of the T-shaped condenser 132, passes through the back plate 136 and the upper side of the diaphragm 137, the air pressure on the upper side of the diaphragm 137 is The air pressure above the diaphragm 137 is smaller than the air pressure below the diaphragm 137. By using the Bernoulli principle, when the air pressure above the diaphragm 137 is smaller than the air pressure below the diaphragm 137, the diaphragm 137 will move upward toward the back plate 136, thereby bringing the back plate 136 and the diaphragm 137 closer. In this process, the airflow completely bypasses the circuit board 133, so that the smoke mixed in the airflow is completely adsorbed in the T-shaped condenser 132, thereby reducing the residual smoke oil on the components on the upper surface of the circuit board 133, which may affect subsequent use.

[0036] In this embodiment, refer to Figure 4-6The adjusting module 3 includes a placement groove 102 provided in the placement cavity 10, the placement groove 102 is communicated with the air outflow hole 1302, a threaded hole 310 is provided on one side of the placement groove 102, a screw rod 30 is provided in the threaded hole 310, preferably, the screw rod 30 is spirally sealed and connected with the threaded hole 310, an adjusting knob 31 is provided on one side of the screw rod 30, a connecting disk 32 is provided on the other side, and the adjusting knob 31 is preferably rotatably connected, a plurality of buffer components are provided on one side of the connecting disk 32, the buffer components include a buffer groove 320 provided on the connecting disk 32, a slider 34 is slidably provided in the buffer groove 320, the slider 34 is connected to the buffer groove 320 by a buffer spring 33, a magnetic plate 35 is provided on the plurality of sliders 34, a rubber ring 37 is provided on the magnetic plate 35, an oil absorption film 36 is provided on the inner ring of the rubber ring 37, and the oil absorption film 36 is preferably detachably connected to the rubber ring 37, during use, the operator can rotate the adjusting knob 31, thereby causing the adjusting knob 31 to drive the screw rod 31 30 is rotated, and after the screw rod 30 is rotated, the screw rod 30 can drive the connecting plate 32 to slide in the mounting groove 102. After the mounting groove 102 slides, it can drive the rubber ring 37 to slide in 103 through the magnetic plate 35. In this process, the rubber ring 37 can adjust the opening size of the air outflow hole 1302, so as to adjust the amount of airflow passing through the air outflow hole 1302, so as to form a strong damping feeling, and by adjusting the gas outflow amount, the amount of smoke inhaled by the user can be further adjusted. After use, the operator can turn the adjustment knob 31 to make the rubber ring 37 block the opening of the air outflow hole 1302, so that the smoke generating module and the airflow sensing chamber 130 are completely blocked at this time, so as to prevent the smoke oil from volatilizing into the airflow sensing chamber 130, and by providing the oil absorption film 36, when the user is in use, a part of the smoke volatilized into the mounting groove 102 can be absorbed by the oil absorption film 36, so as to prevent the smoke from entering the airflow sensing chamber 130 from the air outflow hole 1302.

[0037] In this embodiment, refer to Figure 4-6As shown, an electromagnetic module 38 is provided on one side of the rubber ring 37. The electromagnetic module 38 can be energized after the present invention is turned on. After the electromagnetic module 38 is energized, it generates mutually repelling magnetism with the magnetic plate 35. After the present invention is turned on, the electromagnetic module 38 generates magnetism that is mutually arranged with the magnetic plate 35, so that the magnetic plate 35 drives the rubber ring 37 to move toward the side close to the connecting disk 32. During this process, the buffer spring 33 is compressed, and the opening of the air outflow hole 1302 is automatically opened. After the user uses it, the electromagnetic module 38 stops supplying power. During this process, the buffer spring 33 restores the elastic force, and at this time, the magnetic plate 35 drives the rubber ring 37 to move to the side away from the connecting disk 32, so as to automatically close the opening of the air outflow hole 1302. In this way, when the user forgets to adjust the adjustment knob 31 to make the rubber ring 37 close the air outflow hole 1302 after use, the magnetic plate 35 can still automatically close the opening of the air outflow hole 1302 under the action of the elastic restoring force of the buffer spring 33.

[0038] In this embodiment, refer to Figure 2-3 As shown, the smoke generator 2 includes a smoke cartridge shell 20, on which a smoke oil chamber 201 is provided, in which a hollow tube 21 is provided, in which a smoke chamber 210 is provided, and a suction port 22 is provided on one side of the smoke chamber 210 to communicate with the outside, in which a smoke oil heating component 211 is provided, and on one side of the smoke oil heating component 211, a first power-on block 212 is provided, and the first power-on block 212 is low-connected with a second power-on block 138 provided on the shell 13, and when the airflow brings the back plate 136 and the diaphragm 137 close, the second power-on block 138 is powered by the first power-on block 212, and after the first power-on block 212 is powered, the smoke oil flowing from the smoke oil chamber 201 into the smoke chamber 210 is heated to form smoke, which is then inhaled by the user from the suction port 22.

[0039] In this embodiment, refer to Figure 3As shown, a connecting hole 1303 is provided on one side of the cigarette cartridge shell 20, and the connecting hole 1303 is connected to the smoke chamber 210, and the connecting hole 1303 is connected to the air flow sensing chamber 130 through the air outflow hole 1302. When in use, after the user generates suction from the inlet 22, the external airflow enters the inflow hole 1301 through the air inlet hole 101, and then flows out of the air flow sensing chamber 130 through the condenser from the air outflow hole 1302, and then enters the smoke chamber 210 through the connecting hole 1303. The rubber ring 37 blocks the air outlet hole 1302 and the connecting hole 1303, so that the smoke chamber 210 and the airflow sensing chamber 130 become two independent spaces, thereby preventing smoke from volatilizing into the components on the upper surface of the circuit board 133 in the airflow sensing chamber 130. At the same time, because the rubber ring 37 blocks the connecting hole 1303, a reflux channel cannot be formed at the inlet 22, thereby preventing the smoke oil in 202 from flowing out of the external space through the smoke chamber 210.

[0040] In this embodiment, refer to Figure 2 As shown, the power supply module includes a battery 12 and a control board 11 arranged in the placement cavity 10. Preferably, the battery 12 can be preferably a reciprocatingly rechargeable lithium battery, and a gap is left at one end between the control board 11 and the inner wall of one side of the placement cavity 10, so that external air can enter the airflow sensing cavity 130 through the air inlet 101.

[0041] The remaining unspecified parts of the silicon-microwave airflow sensor (also known as MEMS sensor) are prior art, so the structure will not be described in detail.

[0042] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
