[0002] Electronic cigarettes are electronic products that imitate cigarettes. Although they do not contain tar, they still contain many other carcinogens and have the same appearance, smoke, taste and feel as cigarettes. The World Health Organization has conducted a special study on electronic cigarettes and has come to a clear conclusion: electronic cigarettes are harmful to public health and are not a means of quitting smoking. They must be strictly regulated to prevent harm to teenagers and non-smokers.

[0003] What exactly is an e-cigarette? Public information shows that an e-cigarette is mainly composed of four parts: e-liquid (containing nicotine, flavors, solvent propylene glycol, etc.), heating system, power supply and filter. It produces aerosol with a specific smell for smokers to use through heating and atomization. In a broad sense, e-cigarettes refer to electronic nicotine delivery systems, including e-cigarettes, hookahs, hookah pens and other forms. In a narrow sense, e-cigarettes refer only to portable e-cigarettes that look similar to cigarettes.

[0004] However, the existing electronic cigarettes with holes on the side of the metal shell for inhalation cannot further filter the smoke during the user's smoking process, so that the harmful substances contained in the electronic cigarette will affect the user, further affecting the user's health, making it unfavorable to use.

[0009] 2) At the same time, it can greatly reduce the pollution of smoke oil to the silicon wheat airflow sensor chip.

[0024] Electronic cigarettes are electronic products that imitate cigarettes. Although electronic cigarettes do not contain tar, they still contain many other carcinogens and have the same appearance, smoke, taste and feel as cigarettes. The World Health Organization has conducted special research on electronic cigarettes and reached a clear conclusion: electronic cigarettes are harmful to public health, and they are not a means of quitting smoking. They must be strictly controlled to prevent harm to teenagers and non-smokers. The existing electronic cigarettes that use holes at the bottom of the PCB and slots on the side of the PCB are not convenient for users to connect and separate the metal shell from the cigarette shell, which makes it easy for users to use them normally due to unstable connection between the two, resulting in inconvenience for users to fill new smoke liquid after use. In response to this, the inventor proposed an electronic cigarette that uses holes at the bottom of the PCB and slots on the side of the PCB to solve the above problems.

A plurality of air holes 406 are provided in the electrode plate 405, an outlet groove 304 is provided on the top of the metal shell 3, the PCB board 4 is provided at the bottom of the metal shell 3, and an inlet groove 401 is provided on one side of the bottom of the PCB board 4, and is interconnected with the guide groove 402 provided in the PCB board 4, and then the inlet groove 401 is connected to the connecting port 201, so that the electronic smoke can enter the guide groove 402, and then flow to the back electrode plate 405 through the condensation groove 403, and in the process of the smoke passing through the condensation groove 403, the atomized smoke can be condensed, that is, the smoke condensate is attached to the inner wall of the condensation groove 403, thereby greatly reducing the pollution of the smoke oil to the silicon wheat airflow sensor, and at the same time, the silicon wheat airflow sensor 407 can sense the air pressure inside the electronic cigarette during the user's smoking process, so that the electronic cigarette enters the working state and allows the user to inhale.

[0027] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, in order to further improve the connection performance of the device, a groove 101 is provided on one side of the cigarette shell 1, and two arc grooves 102 are symmetrically provided on the top of one side of the cigarette shell 1, and an atomization bin 2 is provided on the inner circumferential wall of the groove 101. A connecting port 201 is fixedly connected to the top of the atomization bin 2, and a sealing ring 202 is provided on the outer circumferential wall of the connecting port 201. The sealing ring 202 is fixed to the inner circumferential wall of the inlet groove 401. A connecting shaft 302 is provided on one side of the bottom of the metal shell 3, and the metal shell 3 is rotatably connected to the cigarette shell 1 through the connecting shaft 302. Two clamping blocks 301 are symmetrically provided on the other side of the bottom of the metal shell 3, and the two clamping blocks 301 correspond to the two arc grooves 102. The inner circumferential walls of the two clamping blocks 301 are both provided with elastic rubber 303. The connecting shaft 302 is provided on one side of the bottom of the metal shell 3, and the metal shell 3 can be rotatably connected to the cigarette shell 1 through the connecting shaft 302, so that the metal shell 3 can be connected with the connecting shaft 302 as The metal shell 3 is rotated around the center of the circle, and then two clamping blocks 301 are arranged on the other side of the bottom of the metal shell 3, and the inner peripheral wall of the clamping block 301 is connected to the elastic rubber 303. At the same time, two arc grooves 102 are arranged on the top of one side of the cigarette shell 1, and the arc groove 102 corresponds to the clamping block 301, so that after the metal shell 3 rotates around the connecting shaft 302 as the center of the circle, the clamping block 301 can pass through the arc groove 102 to make the elastic rubber 303 collide with the outer peripheral wall of the atomization bin 2, thereby increasing the friction between the atomization bin 2 and the metal shell 3, and facilitating the connection between the connecting port 202 and the inlet groove 401. Therefore, by providing the clamping block 301, after the user manually turns the metal shell 3 around the connecting shaft 302 as the center of the circle, the clamping block 301 can pass through the arc groove 102 to make the elastic rubber 303 collide with the outer peripheral wall of the atomization bin 2, thereby increasing the friction between the atomization bin 2 and the metal shell 3, and facilitating the connection between the connecting port 202 and the inlet groove 401.

[0028] In this embodiment, Figure 1 , Figure 4 and Figure 5As shown, in order to further improve the auxiliary performance of the device, a circular groove is opened on one side of the top of the metal shell 3, and a pressure rod 5 is slidably connected to the inner wall of the circular groove. The end of the pressure rod 5 is fixedly connected to a connecting block 501, and the bottom of the connecting block 501 is fixedly connected to a spring 502. The end of the spring 502 is fixedly connected to the PCB board 4, and two connecting rods 503 are symmetrically arranged on both sides of the connecting block 501. One end of the two connecting rods 503 is hingedly connected to the connecting block 501, and the other ends of the two connecting rods 503 are hingedly connected to a linkage slide rod 504. The middle of the linkage slide rod 504 is fixedly connected to a limit slider 505. The outer The peripheral wall is provided with a cross slot 506, the cross slot 506 is opened in the PCB board 4, the pressure rod 5 is provided in the circular slot, and a connecting block 501 is provided at the end of the pressure rod 5, and then connected with the spring 502 through the connecting block 501, so that the connecting block 501 can have an upward force under the elastic action of the spring 502, and after the connecting block 501 moves upward, since a limit slider 505 is provided in the middle of the linkage slide bar 504, the limit slider 505 can slide horizontally in the cross slot 506, but cannot be deflected up and down, so that the intersection angle between the connecting rod 503 and the connecting block 501 can be changed on this basis. In this way, the distance between the ends of the two connecting rods 503, that is, the distance between the linkage slide bars 504 connected to the ends of the two connecting rods 503, can be changed. After the distance between the two linkage slide bars 504 is changed, the bottoms of the two linkage slide bars 504 can squeeze the connecting port 201. In addition, the connecting port 201 itself is similar to the shape of a funnel, that is, the middle diameter is smaller than the diameters at both ends, so that the connecting port 201 can be squeezed and positioned, thereby avoiding the metal shell 3 from separating after being connected to the cigarette shell 1. When the user manually applies a downward force to the pressure rod 5, the force can be transmitted to the The spring 502 is used to offset the elasticity of the spring 502, so that the connecting block 501 moves downward and the distance between the two linkage slide bars 504 is expanded, so that the user can flip the metal shell 3 and separate it from the cigarette shell 1 at this time. Therefore, by providing the linkage slide bar 504, the elastic action of the spring 501 can make the distance between the two linkage slide bars 504 have a shortened elastic force, so that it can squeeze the connecting port 201, so as to achieve the effect of connecting and fixing the metal shell 3 and the cigarette shell 3. After the user applies a downward force to the pressure rod 5, the user can separate the metal shell 3 from the cigarette shell 1 at this time to assist the user in use.

[0029] The remaining unexplained parts of the silicon-microwave airflow sensor (also known as MEMS sensor) are prior art, so the structure will not be described in detail.

[0030] The specific working process of the present invention is as follows:

[0031] (1) Connect the metal shell 3 to the cigarette shell 1

[0032] First, after the electronic cigarette liquid is poured into the atomizer bin 2, the metal shell 3 is manually turned over so that the clamping block 301 can be pressed against the outer wall of the atomizer bin 2, thereby increasing the tightness between the metal shell 3 and the cigarette shell 1;

[0033] (2) The linkage slide bar 504 squeezes the connection port 201

[0034] Then, under the elastic action of the spring 501 , the distance between the two linkage slide bars 504 can have a reduced elastic force, so that the connection port 201 can be pressed, thereby achieving the effect of connecting and fixing the metal shell 3 and the cigarette shell 3 .

[0035] (3) Allowing the user to use the electronic cigarette by inhaling into the outlet slot 304

[0036] The user can inhale the outlet slot 304 so that the atomization chamber 2 can flow to the outlet slot 304 after atomizing the smoke liquid. In this process, the atomized smoke can be condensed, that is, the smoke condensate is attached to the inner wall of the condensation slot 403, thereby greatly reducing the pollution of the smoke oil to the silicon wheat airflow sensor.

[0037] (4) After using up the e-liquid, add new e-liquid

[0038] After the electronic cigarette is used for a period of time and the smoke liquid is used up, the user can manually apply a downward force to the pressure rod 5 to separate the metal shell 3 from the cigarette shell 1, and the user can then fill in new smoke liquid.

[0039] In summary: the beneficial effects of the present invention are specifically embodied in that the device is improved on the existing basis, and the electronic cigarette using the PCB bottom opening and the PCB side slotted silicon wheat has a better effect, the PCB board 4 is arranged at the bottom of the metal shell 3, and an inlet groove 401 is opened on one side of the bottom of the PCB board 4, and is interconnected with the guide groove 402 opened in the PCB board 4, and then the inlet groove 401 is connected to the connection port 201, so that the electronic smoke can enter the guide groove 402, and then flow to the back plate 405 through the condensation groove 403, and in the process of the smoke passing through the condensation groove 403, the atomized smoke can be condensed, that is, the smoke condensate is attached to the inner peripheral wall of the condensation groove 403, thereby greatly reducing the pollution of the smoke oil to the silicon wheat airflow sensor;

[0040] When the device is in use, the connecting shaft 302 is arranged on one side of the bottom of the metal shell 3, and the metal shell 3 can be rotatably connected with the cigarette shell 1 through the connecting shaft 302, so that the metal shell 3 can rotate with the connecting shaft 302 as the center of the circle. Then, two clamping blocks 301 are arranged on the other side of the bottom of the metal shell 3, and the inner peripheral wall of the clamping block 301 is connected with the elastic rubber 303. At the same time, two arc grooves 102 are provided on the top of one side of the cigarette shell 1, and the arc groove 102 corresponds to the clamping block 301, so that after the metal shell 3 rotates with the connecting shaft 302 as the center of the circle, After the clamping block 301 passes through the arc groove 102, the elastic rubber 303 can collide with the outer peripheral wall of the atomization bin 2, thereby increasing the friction between the atomization bin 2 and the metal shell 3, and facilitating the connection between the connecting port 202 and the inlet groove 401. Therefore, by providing the clamping block 301, after the user manually turns the metal shell 3 around the connecting shaft 302 as the center of the circle, the clamping block 301 can pass through the arc groove 102, and the elastic rubber 303 can collide with the outer peripheral wall of the atomization bin 2, thereby increasing the friction between the atomization bin 2 and the metal shell 3, and facilitating the connection between the connecting port 202 and the inlet groove 401.

[0041] When the device is in use, the pressure rod 5 is arranged in the circular groove, and a connecting block 501 is arranged at the end of the pressure rod 5, and then connected with the spring 502 through the connecting block 501, so that the connecting block 501 can have an upward force under the elastic action of the spring 502, and after the connecting block 501 moves upward, since a limit slider 505 is arranged in the middle of the linkage slide bar 504, the limit slider 505 can slide horizontally in the cross slide groove 506, but cannot be offset up and down, so that the intersection angle of the connecting rod 503 and the connecting block 501 can be changed on this basis, thereby changing the distance between the ends of the two connecting rods 503, that is, the distance between the linkage slide bars 504 connected to the ends of the two connecting rods 503, and after the distance between the two linkage slide bars 504 changes, the bottom of the two linkage slide bars 504 can squeeze the connecting port 201, and the connecting port 201 itself is similar to the shape of a funnel, that is, the middle diameter The spring 502 is smaller than the diameter at both ends, so as to achieve the effect of squeezing and positioning the connecting port 201, and avoid the metal shell 3 from being separated after being connected to the cigarette shell 1. When the user manually applies a downward force to the pressure rod 5, the force can be transmitted to the spring 502 through the connecting block 501 to offset the elasticity of the spring 502, so that the connecting block 501 moves downward and the distance between the two linkage slide bars 504 is enlarged, so that the user can flip the metal shell 3 and separate it from the cigarette shell 1 at this time. Therefore, by providing the linkage slide bar 504, the elastic action of the spring 501 can make the distance between the two linkage slide bars 504 have a shortened elastic force, so that the connecting port 201 can be squeezed, so as to achieve the effect of connecting and fixing the metal shell 3 to the cigarette shell 3. After the user applies a downward force to the pressure rod 5, the user can separate the metal shell 3 from the cigarette shell 1 at this time to assist the user in using the cigarette.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
