[0043] Example 1

[0044] Please see the attached Figure 1 -Attached Figure 3 This embodiment relates to an electronic cigarette, comprising a main body 1, an air-regulating plate 2, a magnetic component 3, and a Hall effect sensor 4. The main body 1 is provided with a first air inlet 111 and a circuit board 12. The air-regulating plate 2 is rotatably connected to the main body 1 along its axis. Rotating the air-regulating plate 2 adjusts the area of ​​the first air inlet 111 that is blocked by the air-regulating plate 2. The magnetic component 3 is disposed on the air-regulating plate 2. The Hall effect sensor 4 is disposed on the side of the circuit board 12 opposite the air-regulating plate 2. Rotating the air-regulating plate 2 adjusts the relative position of the magnetic component 3 and the Hall effect sensor 4.

[0045] In this embodiment, the main body 1 is in the shape of a rectangular parallelepiped as a whole, and a suction nozzle is provided at one end of the main body 1 at the top. The corresponding functional structures such as the air regulating plate 2, the magnetic part 3 and the Hall sensor 4 are all arranged at one end of the bottom of the main body 1. The air regulating plate 2 is a plate member that is circular in shape as a whole and can be made of plastic and formed by injection molding. A first air inlet hole 111 is provided on one side of the bottom of the main body 1. By rotating the air regulating plate 2, the area of ​​the first air inlet hole 111 blocked by the air regulating plate 2 can be adjusted to change the air intake per unit time, thereby achieving convenient adjustment of the air intake volume. Furthermore, a magnetic part 3 is provided on the side of the air regulating plate 2 relative to the circuit board 12. The magnetic part 3 can be a cylindrical permanent magnet. In the process of rotating the air regulating plate 2, the relative position of the magnetic part 3 and the Hall sensor 4 is adjusted in a linked manner, so that the relative position of the magnetic part 3 and the Hall sensor 4 changes, thereby changing the output voltage of the Hall sensor 4, so that the circuit board 12 can adjust the power based on the output voltage of the Hall sensor 4.

[0046] This electronic cigarette can achieve simultaneous adjustment of air intake and power by adjusting the air regulating plate 2. Linking the two adjustment methods can effectively simplify the user's adjustment operation and improve the user's convenience and experience. On the other hand, compared with the prior art that uses a power adjustment device and an airway adjustment device separately, this electronic cigarette can further improve the compactness of the structure and reduce the volume, thereby realizing the miniaturization of the electronic cigarette product.

[0047] Those skilled in the art will appreciate that, through experimentation, the relationship between the rotation angle of the air-regulating plate 2 and the output voltage of the Hall sensor 4 can be calibrated and a reference curve can be fitted. The circuit board 12 then matches the output power of the electronic cigarette based on the output voltage of the Hall sensor 4, thereby adjusting the output power of the electronic cigarette by adjusting the rotation angle of the air-regulating plate 2. Since the magnetic member 3 is disposed on the air-regulating plate 2, the rotation angle of the air-regulating plate 2 can reflect the relative position change between the magnetic member 3 and the Hall sensor 4.

[0048] Optionally, when the magnetic member 3 and the Hall sensor 4 are in facing positions, the first air inlet 111 is completely blocked by the air regulating plate 2 .

[0049] In this embodiment, when the magnetic member 3 and the Hall sensor 4 are completely aligned, the output voltage of the Hall sensor 4 is minimum, and the output power of the electronic cigarette is zero. At this point, the electronic cigarette should be in a non-heating state, and the user cannot inhale. Simultaneously, the first air inlet 111 is completely blocked by the air regulating plate 2, effectively preventing air from entering the air inlet channel 13 through the first air inlet 111. Furthermore, as the air regulating plate 2 is gradually rotated from this position, the actual air intake area of ​​the first air inlet 111 gradually increases. At this point, the relative position of the magnetic member 3 and the Hall sensor 4 is gradually adjusted from completely aligned to a relative offset. For example, the offset can be 10°, 30°, or 60°. The output voltage of the Hall sensor 4 also gradually increases, and the output power of the electronic cigarette also gradually increases. This adjustment scheme meets the user's needs. When the user requires a larger amount of vapor, the air intake should be adjusted to a relatively larger amount to match the higher output power. When the user requires a smaller amount of vapor, the air intake should be adjusted to a relatively smaller amount to match the lower output power.

[0050] Please see the attached Figure 4 and attached Figure 5 Optionally, a limiting groove 22 is provided on a wall surface of the air regulating plate 2 opposite to the circuit board 12 , and the magnetic member 3 is arranged in the limiting groove 22 .

[0051] In this embodiment, the limiting groove 22 should match the shape of the magnetic member 3. Preferably, the magnetic member 3 is a cylinder, and the limiting groove 22 is a cylindrical groove structure. The air regulating plate 2 is a plate-shaped member, and the limiting groove 22 is formed by the wall surface of the air regulating plate 2 on one side opposite to the circuit board 12 being recessed toward the other side. At the same time, a number of snap-in bosses 25 are provided along the circumferential ring at the opening of the limiting groove 22. In this embodiment, a total of four snap-in bosses 25 are provided. When the magnetic member 3 is fully assembled into the limiting groove 22, the snap-in bosses 25 press one end of the magnetic member 3 tightly to prevent the magnetic member 3 from moving or slipping inside the limiting groove 22.

[0052] Optionally, the air-regulating plate 2 is provided with a plurality of guide plates 23 spaced apart along the circumferential direction on a wall surface of a side away from the circuit board 12 .

[0053] In this embodiment, the guide plate 23 is an arc-shaped plate erected on the air regulating plate 2, and the four guide plates 23 are distributed along the circumferential interval. The first air inlet 111 is located inside the circular area formed by the four guide plates 23. Air can enter the circular area through the gaps between the four guide plates 23, and further enter the first air inlet 111 under the guiding action of the guide plates 23.

[0054] Please see the attached Figure 2 and attached Figure 6 Furthermore, the main body 1 includes a sealing member 11 , which defines a first air inlet 111 . The sealing member 11 is fixed on the circuit board 12 and is interference-fitted with the air regulating plate 2 .

[0055] In this embodiment, the seal 11 is made of plastic material, the inner wall of the first air inlet hole 111 is an arc-shaped surface, and the first air inlet hole 111 is a curved strip on the end face of the seal 11. The end face of the seal 11 is in contact with the board surface of the circuit board 12 and can be relatively fixed by bonding or clamping. The air regulating plate 2 and the seal 11 are connected by an interference fit of the hole and the axis.

[0056] Furthermore, a limiting boss 112 is provided on the sealing member 11, and the first air inlet hole 111 is arranged through the limiting boss 112; the circuit board 12 is provided with a limiting hole, and the limiting boss 112 is arranged in the limiting hole and has an interference fit with the limiting hole and the air regulating plate 2.

[0057] In this embodiment, the limiting boss 112 is cylindrical, and the circuit board 12 is provided with a limiting hole corresponding to the position of the limiting boss 112. The limiting boss 112 is passed through the limiting hole, and an interference fit is achieved between the limiting boss 112 and the limiting hole. The seal 11 is made of plastic material and has a certain elastic deformation ability. During assembly, the limiting boss 112 can be elastically deformed so that the limiting boss 112 can be installed in the limiting hole. The interference fit can also ensure a certain sealing performance to avoid air leakage in the limiting hole.

[0058] Optionally, an annular limiting portion 1121 is provided on the outer periphery of the limiting boss 112 , and the limiting portion 1121 presses against the circuit board 12 .

[0059] In this embodiment, the circuit board 12 is confined between the limiting portion 1121 and the sealing member 11 . The limiting portion 1121 can press against the circuit board 12 , further ensuring a reliable connection between the limiting boss 112 and the circuit board 12 .

[0060] Please refer to the attached Figure 3 Furthermore, an end surface of the limiting boss 112 facing the air regulating plate 2 includes a rib 1122 arranged around the first air inlet hole 111.

[0061] In this embodiment, a connection hole is formed on the wall of the side of the air-regulating plate 2 facing the circuit board 12, and a limiting boss 112 is inserted into the connection hole to connect the air-regulating plate 2 with the sealing member 11. When the air-regulating plate 2 rotates, the limiting boss 112 remains stationary, and the air-regulating plate 2 can rotate relative to the limiting boss 112. A rib 1122 is provided on the limiting boss 112. The top of the rib 1122 is arc-shaped and circumferentially arranged around the outer periphery of the first air inlet 111. After the air-regulating plate 2 and the limiting boss 112 are mounted together, the air-regulating plate 2 is pressed against the rib 1122. During the rotation of the air-regulating plate 2, the air-regulating plate 2 also constantly presses against the rib 1122, thereby preventing air from leaking through the gap between the air-regulating plate 2 and the limiting boss 112, thereby ensuring a tight seal.

[0062] Furthermore, the electronic cigarette further includes a knob 5 , which is connected to the air regulating plate 2 . By rotating the knob 5 , the air regulating plate 2 can be driven to rotate by the same angle.

[0063] In this embodiment, a connecting portion 24 is provided on the air-regulating plate 2. The connecting portion 24 is a cylindrical boss. The connecting portion 24 and the air-regulating plate 2 are integrally formed. Rotating the knob 5 conveniently drives the air-regulating plate 2 to rotate. The knob 5 and the air-regulating plate 2 are coaxial and have the same angular velocity, meaning that the knob 5 and the air-regulating plate 2 rotate synchronously. The bracket 6 also has a mounting hole 62, through which the knob 5 is inserted, and the operable portion of the knob 5 protrudes.

[0064] Please see the attached Figure 8 The electronic cigarette further includes a shell 7 , which is an integrated structure and covers the outer periphery of the main body 1 and the bracket 6 . The knob 5 is protruded from the outside of the shell 7 to facilitate the user to manually rotate the knob 5 .

[0065] Example 2

[0066] Please continue to attach Figure 4 and attached Figure 5 This embodiment is basically the same as the first embodiment, except that an air regulating hole 21 is additionally provided on the air regulating plate 2, and the communicating area between the air regulating hole 21 and the first air inlet 111 can be adjusted by rotating the air regulating plate 2.

[0067] In this embodiment, the shape of the air-adjusting hole 21 is adapted to the shape of the first air inlet 111. The air-adjusting hole 21 also adopts the same arc-shaped strip structure as the first air inlet 111 and has the same size. When the air-adjusting plate 2 is rotated, the air-adjusting plate 2 begins to face the first air inlet 111 and completely blocks the first air inlet 111. At this time, the connecting area between the air-adjusting hole 21 and the first air inlet 111 is 0, and the air intake is also 0. Further rotation of the air-adjusting plate 2 causes part of the structure of the air-adjusting hole 21 to face part of the structure of the first air inlet 111, and the air-adjusting hole 21 and the first air inlet 111 are connected. When the air-adjusting plate 2 continues to rotate, the connecting area between the two gradually increases. When the air-adjusting hole 21 and the first air inlet 111 completely overlap, the connecting area is the largest, and at this time, the air intake per unit time is the largest.

[0068] Optionally, the distance between the magnetic member 3 and the central axis of the air-regulating plate 2 is greater than the distance between the air-regulating hole 21 and the central axis of the air-regulating plate 2 .

[0069] In this embodiment, the magnetic member 3 is positioned near the outer side of the circular air-regulating plate 2, preventing the magnetic member 3 from being close to the central axis of the air-regulating plate 2. This allows for faster adjustment of the relative position of the magnetic member 3 and the Hall sensor 4, thereby improving the sensitivity of power adjustment. In this embodiment, the air-regulating hole 21 is closer to the central axis of the air-regulating plate 2 than the magnetic member 3, thereby better accommodating the volume of the magnetic member 3 and facilitating the placement of the magnetic member 3.

[0070] Please see the attached Figure 6 and attached Figure 7 Optionally, the electronic cigarette further includes a bracket 6, which is covered on the circuit board 12 and connected to the main body 1; an air inlet channel 13 is provided inside the main body 1, and the first air inlet hole 111 is connected to the air inlet channel 13, and a second air inlet hole 61 is provided on the bracket 6, and external air can enter the air adjustment hole 21 through the second air inlet hole 61.

[0071] In this embodiment, bracket 6 can be made of either metal or non-metal. It is a housing structure with a certain internal space for accommodating structures such as the air-regulating plate 2 and the limiting boss 112. Bracket 6 is connected to seal 11, specifically by bonding or snapping, and houses circuit board 12. Bracket 6 protects the electronic components on circuit board 12, preventing dust from adhering to circuit board 12 and potentially affecting its performance.

[0072] There is also an air intake channel 13 inside the main body 1, one end of the air intake channel 13 is connected to the first air intake hole 111 at the bottom of the main body 1, and the air intake channel 13 extends toward the direction of the suction nozzle. A second air intake hole 61 is provided on the bracket 6. External air enters the air adjustment hole 21 through the second air intake hole 61, then enters the first air intake hole 111 through the air adjustment hole 21, and finally enters the air intake channel 13 through the first air intake hole 111.

[0073] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
