An operating button 220 protruding downward may be provided on the lower side of the sheet-like body, and the operating button 220 facilitates the user to toggle the device switch 200.

[0057] In one embodiment, a cup seat connection port is provided at one end of the liquid storage cup 300, and the cup seat 400 is sealed at the cup seat connection port. The liquid storage cup 300 and the cup seat 400 form a liquid storage bin 310, and the liquid storage bin 310 is used to store the atomized matrix.

[0058] The atomizing assembly 500 is disposed in the liquid storage cup 300. In a specific embodiment, please refer to Figure 2 , Figure 3 and Figure 6 The atomizing assembly 500 includes a liquid inlet 521, and the liquid inlet 521 is used for the atomizing matrix to enter the atomizing assembly 500. The atomizing assembly 500 includes an outer cylinder 520, a liquid storage cotton 530, an inner sleeve 570, a liquid guide cotton 580 and a heating element 540 arranged in sequence from outside to inside.

[0059] Optionally, the outer cylinder 520 can be a steel pipe, and the liquid inlet 521 is arranged on the outer peripheral surface of the lower end of the outer cylinder 520. The liquid storage cotton 530 is used to buffer the flow of the atomized matrix and transport the atomized matrix from the liquid inlet 521 to the heating element 540. The liquid storage cotton 530 is a hollow structure and can form a channel that runs through from top to bottom. The inner sleeve 570 is arranged in the hollow channel formed by the liquid storage cotton 530, and a sealing member can be arranged between the bottom of the inner sleeve 570 and the bottom of the outer cylinder 520. The inner sleeve 570 can prevent the liquid storage cotton 530 from being directly connected to the liquid guide cotton 580 inside the inner sleeve 570, and prevent the atomized matrix in the liquid storage cotton 530 from flowing directly into the hollow channel formed by the liquid storage cotton 530, thereby avoiding oil leakage. At the same time, the inner sleeve 570 can also position the liquid storage cotton 530 and the liquid guide cotton 580. The liquid-conducting cotton 580 includes an outer convex portion 581, which extends from the avoidance port 571 provided on the side wall of the inner sleeve 570 and contacts the liquid storage cotton 530, so that the atomized matrix infiltrated in the liquid storage cotton 530 can be gradually supplied to the liquid-conducting cotton 580. The heating element 540 is used to heat the atomized matrix to generate an aerosol. The structural form of the heating element 540 is not limited, for example, it can include a heating plate of a cylindrical structure, a thick film heating tube, etc. The heating element 540 is attached to the hole wall of the central opening of the liquid-conducting cotton 580, and can heat the atomized matrix at the liquid-conducting cotton 580 to generate an aerosol. The central hole surrounded by the heating element 540 constitutes an atomization channel. The heating element 540 is connected to the circuit board module 820, and can be powered on and heated under the control of the circuit board module 820, thereby heating the atomized matrix on the surrounding liquid storage cotton 530 and forming an aerosol. The atomizer assembly 500 is an important component in the field of atomizer devices. The structure of the atomizer assembly 500 can refer to the relevant technology. The present application does not limit the specific structure of the atomizer assembly 500.

[0060] The vertically penetrating channel in the center of the atomizing assembly 500 forms an aerosol discharge channel 510, which can discharge the aerosol generated by heating. The top of the atomizing assembly 500 is provided with an upper sealing seat 610, which can communicate with the suction nozzle 120 and seal the connection part.

[0061] In one embodiment, along the extension direction of the aerosol discharge channel 510, the heating element 540 has a first end and a second end, the first end is close to the liquid inlet 521, the second end is far away from the liquid inlet 521, and the setting position of the heating element 540 is closer to the second end. In some related schemes, the atomizing assembly 500 is arranged at the bottom of the liquid storage cup 300, and the liquid level of the atomizing matrix in the liquid storage cup 300 will affect the liquid supply speed of the atomizing assembly 500 (hydraulic pressure P=ρgh, where ρ is density, g is gravity acceleration, and h is liquid level), resulting in abnormalities such as oil leakage or core sticking during use; the atomizing assembly 500 in the utility model adopts the above-mentioned arrangement structure, and the heating element 540 is located in the upper area of ​​the liquid storage cotton 530. The atomizing matrix entering the liquid storage cotton 530 from the liquid inlet 521 spreads to the upper part of the liquid storage cotton 530 to the heating element 540 under the capillary action of the liquid storage cotton 530, which can eliminate the influence of the liquid level in the liquid storage cup 300 on the oil supply speed of the atomizing assembly 500; when the pressure inside the atomizing device is greater than the external environment pressure (such as taking an airplane), it is helpful to avoid the atomizing matrix inside the liquid storage cup 300 being squeezed into the liquid storage cotton 530 and then leaking from the atomizing assembly 500, and the overall anti-leakage effect is better.

[0062] The atomizing assembly 500 includes an air inlet 550. The atomizing device is provided with an air inlet channel 560 connected to the air inlet 550. The air inlet 550 is used for the suction airflow to enter the atomizing assembly 500. In a specific embodiment, please refer to Figure 2 , Figure 3 , a bottom groove is provided on the bottom surface of the cup holder 400, and a lower sealing seat 620 is provided at the bottom of the bottom groove. The lower sealing seat 620 is sealed with the bottom of the cup holder 400, so that an air inlet cavity is formed in the cup holder 400. At the same time, a downwardly extending tube portion is provided on the lower sealing seat 620, and the lower end of the tube portion passes through the circuit board module 820 and elastically adheres to the device switch 200, and can be connected with the vent hole 230 provided on the device switch 200. When the device switch 200 is active, the connection area between the vent hole 230 and the air inlet channel 560 can be adjusted, thereby realizing air intake adjustment. It should be noted that the device switch 200 in the present utility model is to realize the connection of the power supply, and does not mean that the device switch 200 can generate atomizers at the same time after it is turned on. In addition, the air intake adjustment can be the adjustment of the closed state and the open state, or the adjustment of the small ventilation volume and the large ventilation volume. The air inlet channel 560 on the atomizing device connected to the air inlet 550 of the atomizing assembly 500 may include a through hole provided at the bottom of the cup holder 400, an air inlet cavity surrounded by the cup holder 400 and the lower sealing seat 620, and a tube portion on the lower sealing seat 620. Of course, in some other embodiments, according to the specific structure of the atomizing assembly 500, the air inlet channel 560 may also be replaced with other forms.

[0063] If the liquid storage tank 310 is directly connected to the liquid inlet 521 of the atomizer assembly 500, the atomized matrix in the liquid storage tank 310 may enter the atomizer assembly 500 too much and cause the atomized matrix to leak from the atomizer assembly 500, especially when the atomizer device is transported. In order to avoid leakage of the atomizer assembly 500, the atomizer device also includes a liquid supply tank 440, which is connected to the liquid inlet 521, and an isolation structure is provided between the liquid storage tank 310 and the liquid supply tank 440, and a tank body connection hole 430 for connecting the liquid storage tank 310 and the liquid supply tank 440 is provided on the isolation structure; at the same time, the atomizer device also includes a liquid supply switch 700, which is movably arranged at the tank body connection hole 430 to open and close the tank body connection hole 430.

[0064] In one embodiment, the liquid supply tank 440 is disposed in the cup holder 400. Specifically, the cup holder 400 is provided with a first seat body 411 and a second seat body 412 arranged at intervals along the direction of the cup holder connection port, and the liquid supply tank 440 is formed by the interval between the first seat body 411 and the second seat body 412, and the first seat body 411 forms the above-mentioned isolation structure; the outer cylinder 520 passes through the first seat body 411 and is inserted on the second seat body 412, and the liquid inlet section of the outer cylinder 520 is located in the interval. A connecting body 413 is provided between the first seat body 411 and the second seat body 412 of the cup holder 400, and the connecting body 413 is arranged at positions near the sides on the left and right sides of the cup holder 400, as well as at positions on the left and right sides of the socket on the cup holder 400 for inserting the outer cylinder 520, for realizing the connection between the first seat body 411 and the second seat body 412. The first seat body 411, the second seat body 412 and the connecting body 413 of the cup holder 400 can be integrally formed, and at least one of them can also be separately manufactured and assembled into one with the other parts. In order to ensure the sealing of the liquid supply tank 440, in one embodiment, the outer circumferences of the first seat body 411 and the second seat body 412 are respectively provided with sealing rings (not shown in the figure), and the sealing rings can be sealed with the inner wall of the liquid storage tank 310.

[0065] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5The liquid supply switch 700 includes a valve core 710, a guide hole 421 is provided on the cup holder 400, the guide hole 421 is coaxially arranged with the tank body connection hole 430, and the valve core 710 is movably arranged in the guide hole 421. In order to realize the opening and closing of the tank body connection hole 430, in a specific embodiment, the valve core 710 has a sealing section 720 and a flow section 730; the sealing section 720 is located at one end of the valve core 710 close to the liquid storage tank 310, and a sealing part is provided on the outer peripheral surface of the sealing section 720, and the sealing part is used to seal with the inner wall of the tank body connection hole 430. When the valve core 710 is opened, the sealing section 720 enters the liquid storage tank 310, and there is a gap between the outer peripheral surface of the flow section 730 and the hole wall of the tank body connection hole, and the gap allows the atomized matrix to pass through the tank body connection hole 430.

[0066] In a specific embodiment, a sealing ring groove is provided on the sealing portion of the valve core 710, and a sealing ring can be provided in the sealing ring groove to ensure the sealing effect. Considering the flow rate and efficiency of the atomized substrate, the flow section 730 on the valve core 710 is a cylinder, the cross section of the cylinder is a cross, and a groove extending in the up-down direction is provided on the outer peripheral surface, so that the atomized substrate can pass smoothly. Of course, in a specific embodiment, the cross section of the flow section 730 can also be other shapes.

[0067] The movement direction of the valve core 710 when it is opened is upward. After the valve core 710 moves upward until the sealing section 720 is separated from the tank body connection hole 430, it can be conducted by relying on the flow section 730. In some other embodiments, the valve core 710 can also adopt other structures, and can be opened by moving downward. For example, the valve core 710 can move downward until the sealing section 720 passes over the liquid supply tank 440, so that the tank body connection hole 430 is fully opened; for another example, the sealing section 720 of the valve core 710 can adopt an end face sealing form, that is, the upper end face of the sealing section 720 blocks the lower end edge of the tank body connection hole 430 to achieve sealing. At this time, the valve core 710 moves downward to open the tank body connection hole 430.

The valve core 710 is provided with guide protrusions 740 on both sides of the front and rear, and the guide protrusions 740 can be assembled into the guide grooves 422. Of course, those skilled in the art can understand that the valve core 710 can adopt any guide structure to achieve active assembly.

[0069] A linkage structure is provided between the device switch 200 and the liquid supply switch 700, and the linkage structure is used to open the liquid supply switch 700 when the device switch 200 is switched to the open state. In one embodiment, the linkage structure is a single linkage structure, and when the liquid supply switch 700 is opened, the linkage between the device switch 200 and the movable valve core 710 is released. Optionally, the linkage structure includes an elastic reset member 760, which is connected to the valve core 710, and the elastic reset member 760 is used to apply a force to the valve core 710 to move in the opening direction; the moving direction of the valve core 710 is perpendicular to the moving direction of the device switch 200, and the linkage structure includes a limiting structure 750 provided on the valve core 710; when the device switch 200 is in the closed state, the device switch 200 blocks the limiting structure 750 to limit the movement of the valve core 710 acted on by the elastic reset member 760 in the opening direction; when the device switch 200 is in the open state, the device switch 200 releases the limiting structure 750.

[0070] In a specific embodiment, the linkage structure includes a slot provided on the device switch 200, the slot of the slot faces the valve core 710, and the limiting structure 750 is a limiting protrusion provided on the outer peripheral surface of the valve core 710. The limiting protrusion can be provided at two locations, front and back, which is conducive to making the force of the valve core 710 more balanced. The slot is used to be fixed on the valve core 710 in a direction perpendicular to the axial direction of the valve core 710 and block the limiting protrusion.

[0071] In order to realize the installation of the elastic reset member 760, in one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The valve core 710 includes a hollow section, which is located at one end of the valve core 710 away from the liquid storage tank 310. The elastic reset member 760 is a compression spring, which is arranged in the hollow section, and the two ends of the compression spring are respectively supported on the inner end surface of the hollow section and the device housing 100. A positioning column can be arranged on the device housing 100, and the compression spring can be sleeved on the positioning column, which is conducive to ensuring the stability of the compression spring and the smooth movement of the valve core 710.

[0072] It should be noted that, in some other embodiments, the linkage structure may also be in other forms, as long as the liquid supply switch 700 can be opened synchronously when the device switch 200 is turned on, and the liquid supply switch 700 may also be opened with the opening of the device switch 200 and closed with the closing of the device switch 200. For example, a pin hole may be provided on the valve core 710, and a latch may be provided on the device switch 200, and the latch may be inserted into the pin hole to limit the position of the liquid supply switch 700; for another example, an inclined plane inclined upward may be provided on the device switch 200, and the liquid supply switch 700 may be pushed upward to open by the inclined plane when the device switch 200 is turned on; for another example, for the liquid supply switch 700 that moves downward to open, an inclined plane inclined downward may be provided on the device switch 200, and the liquid supply switch 700 may be pushed downward to open by the inclined plane when the device switch 200 is turned on. In addition, in some other embodiments, when the device switch 200 can push the liquid supply switch 700 to move, the elastic reset member 760 may also be omitted.

[0073] During transportation, if Figure 2 , Figure 3 , the device switch 200 is located at the far right and is in a closed state, and the liquid supply switch 700 is located at the far bottom and is also in a closed state. The atomized matrix in the liquid storage tank 310 cannot enter the liquid supply tank 440, let alone the atomizing assembly 500, which can effectively prevent the atomized matrix from leaking from the atomizing assembly 500. When the user turns on the device switch 200 for the first time, Figure 7 , Figure 8 , the liquid supply switch 700 is synchronously opened and kept in the open state by means of the linkage structure, and the subsequent action of the device switch 200 will not affect the state of the liquid supply switch 700, and the atomized matrix in the liquid storage tank 310 can flow into the liquid supply tank 440 to continuously supply liquid to the liquid storage cotton 530. When the device switch 200 is turned on for the first time, there is no atomized matrix in the liquid storage cotton 530. In order to avoid the user starting to draw without waiting for the liquid storage cotton 530 to soak the atomized matrix and causing the liquid storage cotton 530 to burn, a certain amount of atomized matrix can be pre-stored in the liquid storage cotton 530, so that the user does not need to wait for the core to be moistened (i.e., the liquid storage cotton 530 soaks the atomized matrix), and the burning problem can also be avoided.

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.
