Referring to fig. 11 and 12, the supply assembly 22 includes a base 221, a screw 226, a connecting member 224, and a driving member 222. Wherein, the driving member 222 is connected with the screw rod 226, a driving shaft (not shown in the figure) of the driving member 222 can drive the screw rod 226 to rotate, the connecting member 224 is in transmission connection with the screw rod 226, and the connecting member 224 is also connected with the piston body 232.

Specifically, the screw rod 226 is rotatably disposed on the base 221, the connecting piece 224 is connected with the piston body 232 through the push rod 225, when the driving shaft of the driving piece 222 drives the screw rod 226 to rotate, the connecting piece 224 can move up and down along the screw rod 226, and the connecting piece 224 can drive the piston body 232 to move up and down in the liquid storage cavity 2311 through the push rod 225. When the piston body 232 moves upward in the liquid storage cavity 2311, the volume of the liquid storage cavity 2311 becomes smaller and the pressure becomes larger, so that the atomized liquid in the liquid storage cavity 2311 is transferred from the bottle mouth 2312, the connecting pipe 13 and the liquid inlet pipe 126 into the atomized cavity 1220.

The connecting piece 224 may be a sliding block, which is sleeved on the outer circumference of the screw rod 226, and the push rod 225 is connected between the sliding block and the piston body 232.

The drive member 222 may be a stepper motor, a motor, or any other device having a rotatable drive shaft, and is not limited in this regard. Because the duration of the single operation of the driving member 222 can be precisely controlled, the distance that the connecting member 224 drives the piston body 232 to move up and down through the push rod 225 can be precisely controlled, and further, the capacity of the atomized liquid which is transferred into the atomizing cavity 1220 at a single time can be precisely controlled, so that the harm to the human body caused by the fact that the user ingests excessive aerosol at a single time is avoided.

In addition, in the existing aerosol generating device, in order to realize the conveying and supplying of the atomized liquid, the micro pump is mainly adopted for actively pumping the atomized liquid, but the micro pump is generally hexahedral and relatively long in size, so that the miniaturization of the aerosol generating device is directly affected, a large number of external pipelines and interfaces are needed for connecting the atomizer and the liquid storage device, the integration degree of the aerosol generating device is directly affected, and the assembly is not easy.

In the application, the driving piece 222 drives the screw rod 226 to rotate, the connecting piece 224 drives the piston body 232 to move up and down in the liquid storage cavity 2311, so that the directional quantitative conveying of atomized liquid is realized, the number of external pipelines and interfaces is reduced, the integration degree of the aerosol generating device 100 is improved, and the assembly is easy; at the same time, the size of the driving member 222 is relatively small, which is advantageous for the miniaturized design of the aerosol-generating device 100.

In some embodiments, the supply assembly 22 further includes a guide rod 227, and the connecting member 224 is provided with a guide hole (not shown) therethrough, and the guide rod 227 is inserted into the guide hole, so that the connecting member 224 can move up and down along the guide rod 227, and the connecting member 224 is prevented from being deviated during the moving process.

The supply assembly 22 further includes a buffer spring (not shown) sleeved on the guide rod 227, and one end of the buffer spring abuts against the connecting member 224. When the connecting piece 224 moves upwards along the screw rod 226, the buffer spring is in a compressed state and the length is continuously reduced, so that the movement of the connecting piece 224 is more stable, and when the driving piece 222 stops rotating, the problem that the connecting piece 224 continuously moves a certain distance due to inertia to cause excessive dosage of atomized liquid transmitted to the atomization chamber 122 is avoided, so that the volume of the atomized liquid transmitted to the atomization assembly 12 at a time can be accurately controlled.

The aerosol generating device 100 further comprises a grating sensor 228 and a controller 27. Wherein the grating sensor 228 is connected to the driving shaft of the driving member 222, such that the grating sensor 228 can be used to detect the number of turns of the driving shaft; the controller 27 is electrically connected to the grating sensor 228 such that the controller 27 can be used to determine whether the number of turns is equal to a preset maximum number of turns and to control the drive shaft to stop rotating and/or to switch the direction of rotation when the number of turns is equal to the maximum number of turns.

Specifically, when the driving member 222 drives the screw rod 226 to rotate in the positive direction, the connecting member 224 moves upward along the screw rod 226; when the driving member 222 drives the screw 226 to rotate in the opposite direction, the connecting member 224 moves downward along the screw 226.

When the number of turns of the driving shaft rotating in the positive direction reaches the preset maximum number of turns, the controller 27 can control the driving piece 222 to stop rotating, so as to avoid the damage to the liquid storage assembly 23 caused by the fact that the piston body 232 continues to move upwards to be contacted with the inner top wall of the bottle body 231; and/or, the controller 27 may control the driving member 222 to rotate in the opposite direction to restore the piston body 232 to the original position (i.e., the bottom of the bottle body 231), and when the number of turns of the driving shaft in the opposite direction reaches the preset maximum number of turns, the controller 27 may control the driving member 222 to stop rotating, thereby preventing the piston body 232 from falling off from the bottle body 231 and preventing the atomized liquid remained in the bottle body 231 from possibly escaping.

In some embodiments, the controller 27 may also be configured to obtain duration data indicating a single operation of the driver 222, and to control the driver 222 to operate according to the duration data. The duration data of the single operation is the duration of each operation of the driving element 222.

Since the distance of the single upward or downward movement of the link 224 along the screw rod 226 can be precisely controlled by controlling the driving member 222 to operate according to the time length data, the volume of the atomized liquid transferred to the atomizing chamber 122 at a single time can be timely and precisely controlled according to the user's needs.

Specifically, each time the driver 222 is actuated, the connector 224 is moved up and/or down the screw 226 a single time a distance of 0.1mm to 0.3mm, such that the volume of atomized liquid delivered into the atomizing assembly 12 in a single time is 5 μl to 20 μl. The distance that the connector 224 moves up and/or down the screw 226 may be, in particular, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc., and the volume of atomized liquid delivered into the atomizing assembly 12 may be, in particular, 5 μl, 10 μl, 15 μl, 20 μl, etc.

In some embodiments, the diameter of the driver 222 is 3 mm-15 mm, resulting in a smaller size driver 222, reducing the space within the power rod 2 required for mounting the driver 222, facilitating a compact design of the aerosol-generating device 100. The diameter of the driver 222 may be specifically 3mm, 6mm, 9mm, 10mm, 12mm, 15mm, etc.

In some embodiments, the supply assembly 22 further includes a speed reducer 223, and the driving shaft of the driving member 222 is connected with the screw rod 226 through the speed reducer 223, so that the thrust force born by the piston body 232 is 0.5N-5N, so that the thrust force born by the piston body 232 is adapted to the viscosity of the atomized liquid, and incomplete atomization caused by too high speed of the atomized liquid transmitted to the atomization chamber 122 due to too high thrust force and dry combustion caused by too low speed of the atomized liquid transmitted to the atomization chamber 122 due to too low thrust force are avoided.

The thrust force applied by the piston body 232 may be specifically 0.5N, 1N, 1.5N, 2N, 2.5N, 3N, 3.5N, 4N, 4.5N, 5N, etc.

Specifically, the speed reducer 223 may be a speed reducer box or any other device with a speed reducing function, which is not limited herein. Illustratively, the speed reducer 223 may be a reduction gearbox, in which a reduction gear set is disposed, and the driving shaft of the driving member 222 is connected to the screw rod 226 through the reduction gear set.

In some embodiments, the user may press the button 20, so that the first control panel 271 receives the start signal, the first control panel 271 transmits the start signal to the second control panel 272, and the second control panel 272 may control the driving member 222 to start working, so that the atomized liquid in the liquid storage cavity 2311 is transferred into the atomized cavity 1220; the first control panel 271 controls the heating body 123 to start to operate so as to perform atomization treatment on the atomized liquid transferred into the atomizing chamber 1220 and generate mist droplets.
