In the initial state, the liquid guide hole and the liquid guide channel 34 are staggered and not connected, and the liquid guide channel 34 is closed, and the air inlet hole and the air inlet channel 35 are staggered and not connected, and the air inlet channel 35 is closed; the toggle plate 42 rotates a certain angle to the use state, in which the liquid guide hole and the liquid guide channel 34 are axially aligned and connected, and the liquid guide channel 34 is opened, and the air inlet hole and the air inlet channel 35 are axially aligned and connected, and the air inlet channel 35 is opened. The toggle plate 42 can also realize the simultaneous opening and closing of the liquid guide channel 34 and the air inlet channel 35 by rotating.

[0074] In this embodiment, the non-power gear is a liquid and gas regulating gear. After switching from the first gear to the second gear, the liquid guide channel 34 can be opened to allow the atomization matrix to enter the atomization core 2. The atomization core 2 is moistened before starting the atomization core 2 for heating, so as to avoid dry burning of the atomization core 2.

[0075] In one embodiment, an electronic atomization device is provided. The difference between the electronic atomization device and the above-mentioned embodiment is that the power gear is a power and gas adjustment gear.

[0076] Please refer to Figures 8 to 12 In this embodiment, the power gear includes a third gear and a fourth gear. In the third gear, the toggle plate 42 opens part or part of the air intake passage 35, and the toggle plate 42 drives the toggle switch 52 to switch to the first power gear; in the fourth gear, the toggle plate 42 opens all the air intake passages 35, and the toggle plate 42 drives the toggle switch 52 to switch to the second power gear. Among them, the opening of the air intake passage 35 in the third gear is smaller than the opening of the air intake passage 35 in the fourth gear, so as to achieve different air intake sizes and corresponding heating powers, so as to achieve high heating power corresponding to large air intake volume, and low heating power corresponding to small air intake volume.

[0077] In this embodiment, a first air inlet hole 4221 and a second air inlet hole 4222 are provided at one end of the toggle plate 42 away from the liquid storage chamber 11. The first air inlet hole 4221 and the second air inlet hole 4222 are arranged side by side along the moving direction of the toggle plate 42, and the first air inlet hole 4221 and the second air inlet hole 4222 are perpendicular to the moving direction of the toggle plate 42, and the sum of the spacing between the first air inlet hole 4221 and the second air inlet hole 4222 plus their respective diameters is equal to or less than the diameter of the air inlet channel 35. The first air inlet hole 4221 is farther away from the liquid storage chamber 11 than the second air inlet hole 4222, that is, the first air inlet hole 4221 is located at the lower end of the second air inlet hole 4222, so that when the toggle plate 42 moves, the first air inlet hole 4221 is connected with the air inlet channel 35 first. Among them, the aperture size and number of the first air inlet hole 4221 and the second air inlet hole 4222 can be set according to needs. For example, two second air inlet holes 4222 are provided, so that in the fourth gear, there are three air inlet holes connected to the air inlet channel 35 to increase the air intake volume.

[0078] Please refer to Figure 8 and Fig. 9 When the toggle plate 42 is switched to the third gear, the first air inlet hole 4221 is aligned and connected with the air inlet channel 35, and the second air inlet hole 4222 is not aligned and connected with the air inlet channel 35. The external through hole can enter the air inlet channel 35 through the first air inlet hole 4221; please refer to Fig.10 and Fig.11When the toggle plate 42 is switched to the fourth gear, the first air inlet hole 4221 and the second air inlet hole 4222 are aligned and connected with the air inlet channel 35, and the external through hole can enter the air inlet channel 35 through the first air inlet hole 4221 and the second air inlet hole 4222. The air intake during the fourth gear suction is greater than the air intake during the third gear suction.

[0079] In other embodiments, the toggle plate 42 is provided with an air inlet hole 422, and the diameter of the air inlet hole 422 is substantially equal to the diameter of the air inlet passage 35; when the toggle plate 42 is switched to the third gear, part of the air inlet hole 422 is aligned and communicated with the air inlet passage 35, and the other part of the air inlet hole 422 is not aligned and communicated with the air inlet passage 35, that is, the cross-sectional area of ​​the air inlet hole 422 communicating with the air inlet passage 35 is smaller; when the toggle plate 42 is switched to the fourth gear, all of the air inlet holes 422 are aligned and communicated with the air inlet passage 35, that is, the cross-sectional area of ​​the air inlet hole 422 communicating with the air inlet passage 35 is larger. This structure can also make the air intake amount during the fourth gear suction greater than the air intake amount during the third gear suction.

[0080] In other embodiments, the first air inlet hole 4221 and the second air inlet hole 4222 are provided at one end of the toggle plate 42 away from the liquid storage chamber 11, and the air inlet channel 35 includes two upper and lower parallel air inlet channels 35. When the toggle plate 42 is switched to the third gear, the first air inlet hole 4221 is aligned and connected with the air inlet channel 35 located above, and the second air inlet hole 4222 is not connected with the air inlet channel 35 located below; when the toggle plate 42 is switched to the fourth gear, the first air inlet hole 4221 is aligned and connected with the air inlet channel 35 located below, and the second air inlet hole 4222 is aligned and connected with the air inlet channel 35 located above. This structure can also make the air intake amount during the fourth gear suction greater than the air intake amount during the third gear suction.

[0081] Please refer to Fig.12 In this embodiment, the electronic component may further include an air pressure sensor 56, which is mounted on the circuit board 51. The second bracket 32 ​​is provided with a detection airway 321, which is connected to the air inlet channel 35. One end of the air pressure sensor 56 is connected to the detection airway 321. The circuit board 51 is provided with a through hole, and the other end of the air pressure sensor 56 is connected to the outside air through the through hole of the circuit board 51. When the toggle plate 42 moves to the third gear and the fourth gear, the air inlet channel 35 is opened. When the user inhales, the outside air will enter the atomizer core 2 through the air inlet channel 35. The air pressure sensor 56 can detect the air pressure change in the air inlet channel 35, and then trigger the control of the heating body 23 to start heating. That is, under the power gear, the user's puffing action can start the heating of the heating body 23 while inhaling air.

[0082] In this embodiment, the electronic atomization device divides the power gear into the third gear and the fourth gear, so as to adjust the power and the air intake at the same time to meet different smoking needs. In other embodiments, the use state can also be divided into more use states, for example, divided into three use states, forming three different air intake sizes, so as to enrich the inhalation adjustability of the electronic atomization device and meet the inhalation needs of more people.

[0083] In one embodiment, an electronic atomization device is provided. The difference between the electronic atomization device and the above-mentioned embodiment is that a limiting structure of a toggle plate 42 is added.

[0084] Please refer to Figures 2 to 11 In this embodiment, a limit structure is added between the toggle plate 42 and the circuit board 51, so that after the toggle plate 42 moves to the second gear, it can no longer return to the first gear. The toggle plate 42 can only be switched between the second gear to the fourth gear. Among them, the first gear is the initial state, which is also the factory state. The liquid guide channel 34 and the air inlet channel 35 are both closed and cannot be used in this state; such a setting can prevent the liquid guide channel 34 from closing and the atomizer core 2 from burning dry.

[0085] The lower end of the toggle plate 42 away from the liquid storage chamber 11 is provided with a first clamping portion 423, and the circuit board 51 is provided with a second clamping portion 511. The first clamping portion 423 can be a buckle with a barb, and the buckle has a guide surface, and the second clamping portion 511 can be a through hole that penetrates the circuit board 51. When the toggle plate 42 moves to the second gear, the guide surface of the buckle passes through the through hole along the edge of the through hole, and the barb of the buckle passes through from one side of the circuit board 51 to the other side through the through hole. After the barb of the buckle passes through the circuit board 51, it cannot return to the original path. When returning, the barb of the buckle will be blocked by the circuit board 51, but the barb of the buckle can continue to move downward. With such a configuration, after the toggle plate 42 is switched to the second gear, it can only switch between the second gear, the third gear and the fourth gear, and cannot return to the first gear.

[0086] The end of the toggle plate 42 may be provided with two first clamping portions 423 symmetrically spaced apart. This arrangement can improve the stability of the movement of the toggle plate 42 and the stability of the first clamping portions 423 deforming through the through hole.

[0087] In other embodiments, the first clamping portion 423 and the second clamping portion 511 may also be other structures. For example, the first clamping portion 423 is an inverted cone structure and the second clamping portion 511 is a through hole, which can also realize a one-way movable connection between the toggle plate 42 and the circuit board 51.

[0088] In other embodiments, the second clamping portion 511 may also be disposed on the fixing frame 3. For example, the second clamping portion 511 is a protrusion having an upwardly inclined surface disposed in the sliding channel 36, and the first clamping portion 423 is a protrusion having a downwardly inclined surface of the toggle plate 42. The two may also realize a one-way movable connection.

[0089] In other embodiments, the length of the toggle plate 42 can be adjusted so that the first clamping portion 423 is connected to the second clamping portion 511 only when the toggle plate 42 is switched to the third gear, that is, when the toggle plate 42 moves to the third gear, the hook of the toggle plate 42 passes through the through hole of the circuit board 51, and the toggle plate 42 can only switch back and forth between the third gear and the fourth gear, and the toggle plate 42 can no longer switch to the first gear and the second gear. Such a setting can also meet the use requirements of some scenarios.

[0090] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
