[0055] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0056] Referring to Figures 1 to 4 , the present invention provides an aerosol generating device 1, including: a main body 10, the main body 10 includes a housing, the main body 10 has a heating chamber 11 extending along a first direction ( Figure 1 and Figure 2 as shown by the X direction in Figure 8 ), an aerosol passage is formed in the heating chamber 11, the heating chamber 11 has an inlet 111 for the aerosol forming substrate 2 to enter and an air flow outlet 115 (refer to Figure 8 described later), optionally, along the first direction, the inlet 111 and the air flow outlet 115 of the aerosol passage are located on opposite sides of the heating chamber 11; optionally, along the first direction, the inlet 111 and the air flow outlet 115 of the aerosol passage are spaced apart.

[0057] It further includes: a sliding part 20, which is installed on the main body 10 in a slidable manner and can slide between a first position and a second position. Optionally, the sliding part 20 can slide between the first position and the second position along the first direction; wherein, referring to Figure 3 and Figure 4 , in the first position, the sliding part 20 is in a retracted state. Optionally, the inlet 111 is covered by the sliding part 20. Preferably, the circuit between the heating element and the power supply is in a conductive state; referring to Figure 1 and Figure 2 , in the second position, the sliding part 20 is in an open state, the inlet 111 is opened, and the aerosol forming substrate 2 can be put into the heating chamber 11 from the inlet 111. Preferably, the circuit between the heating element and the power supply is in an open state.

[0058] Optionally, referring to Figure 2 , Figures 4 to 6, a first slider 40 is provided on the main body 10, and a second slider 41 is provided on the sliding part 20. The second slider 41 and the first slider 40 cooperate with each other, and the second slider 41 and the first slider 40 can slide relative to each other in the first direction. The type of the slider between the sliding part 20 and the main body 10 is not limited, and the cooperation mode between the sliders is not limited either, as long as relative sliding can be generated. Optionally, one of the first slider 40 and the second slider 41 is a slide rail, and the other is a slide groove. In this embodiment, the first slider 40 is a slide rail and the second slider 41 is a slide groove. In other embodiments, other types of sliders can be used, such as guide rods and sliding sleeves.

[0059] Adopting the above technical solution, when it is necessary to put the aerosol-forming substrate 2, the sliding part 20 slides from the first position to the second position ( Figure 1 and Figure 2 the sliding direction is shown in the B direction in), the inlet 111 opens, and the aerosol-forming substrate 2 enters the heating chamber 11 from the inlet 111. At this time, the circuit between the heating element and the power supply is in an open state. No matter how the aerosol generating device 1 is started, the heating element cannot perform the heating operation, that is, the power of the power supply will not be consumed.

[0060] When the aerosol-forming substrate 2 is loaded into the heating chamber 11, the sliding part 20 slides from the second position to the first position ( Figure 4 the sliding direction is shown in the C direction in), the inlet 111 is covered by the sliding part 20. At this time, the circuit between the heating element and the power supply is in a conducting state, and the power supply can be started to make the heating element perform the heating operation. The power supply supplies power to the circuit in the aerosol generating device, and the heating element is used to heat the aerosol-forming substrate 2, and the generated aerosol flows out from the air flow outlet of the aerosol channel for the user to inhale.

[0061] With such a setting, the aerosol generating device 1 can be prevented from being accidentally started, and the power endurance of the aerosol generating device 1 can be improved; by sliding the sliding part 20 between the first position and the second position, the problem of power consumption caused by accidental triggering under no load is solved, and the structure is simple and the cost is low.

[0062] In other words, the heating chamber 11 and the sliding part 20 of the present invention are distributed along the first direction, and the first direction is the overall extension direction of the aerosol generating device 1. After opening the sliding part 20 on the side of the aerosol generating device 1, place the aerosol-forming substrate 2 at the notch 112 described later and place it into the heating chamber 11 through the inlet 111.

[0063] Optionally, referring to Figure 2 and Figure 4 , a first conduction area 12 is provided on the main body 10 of the present invention, and a second conduction area 21 is provided on the sliding part 20. In the first position, the first conduction area 12 and the second conduction area 21 are in contact (asFigure 4 As shown, the circuit is in a conducting state; in the second position, the first conducting region 12 and the second conducting region 21 are separated (as Figure 2 shown), and the circuit is in an open state.

[0064] Among them, the position of the first conducting region 12 on the main body 10 is not restricted, the position of the second conducting region 21 on the sliding part 20 is not restricted, and the materials of the first conducting region 12 and the second conducting region 21 are not restricted; in addition, the form of contact between the first conducting region 12 and the second conducting region 21 is not restricted. It can be electrically connected to make the circuit in a conducting state; it can also be mechanically connected, and the circuit is made to be in a conducting state through a control switch, meeting the following conditions: in the first position, the first conducting region 12 and the second conducting region 21 are in contact, and the circuit is in a conducting state; in the second position, the first conducting region 12 and the second conducting region 21 are separated, and the circuit is in an open state.

[0065] Specifically, in this embodiment, referring to Figure 1 , the first conducting region 12 includes a first conducting spring piece 121 and a second conducting spring piece 122 that are spaced apart and in an open state. The first conducting spring piece 121 and the second conducting spring piece 122 are respectively connected to the positive and negative electrodes of the power supply; optionally, the first conducting spring piece 121 and the second conducting spring piece 122 are spaced apart along the second direction ( Figure 1 as shown by the Y direction in

[0066] ), and the second direction is perpendicular to the first direction. Optionally, the first conducting region 12 is made of a metal material. In some embodiments, the first conducting spring piece 121 and the second conducting spring piece 122 are distributed on the main body 10 in other forms, such as being spaced apart along the first direction, being offset in the second direction, etc. Figure 5 Referring to

[0067] Referring toFigure 2 and Figure 3 A limiting part 14 is provided on the main body 10 to limit the end position of the sliding part 20 moving away from the heating chamber 11 in the first direction. Optionally, the end position of the sliding part 20 moving away from the heating chamber 11 in the first direction is the second position. A notch 112 is provided between the limiting part 14 and the heating chamber 11, which is equivalent to the notch 112 being located on the side of the aerosol generating device 1. Optionally, a nozzle 14 described later is provided on the top surface of the aerosol generating device 1, a USB charging interface is provided on the bottom surface of the aerosol generating device 1, and the side surface of the aerosol generating device 1 is between the top surface of the aerosol generating device 1 and the bottom surface of the aerosol generating device 1. The aerosol forming substrate 2 can be placed and taken out at the notch 112, and the first conduction area 12 is provided on the base 13 at the notch 112.

[0068] Wherein, at least a part of the first conduction elastic sheet 121 and / or the second conduction elastic sheet 122 extends out of the base 13 and can be pressed in the third direction ( Figure 2 shown as the Z direction in the figure) to generate deformation, and the third direction is perpendicular to the first direction. In this embodiment, both the first conduction elastic sheet 121 and the second conduction elastic sheet 122 extend out of the base 13. Since the first conduction elastic sheet 121 and the second conduction elastic sheet 122 can be pressed to generate deformation, this is conducive to the separation of the first contact area 211 and the first conduction elastic sheet 121, and the separation of the second contact area 212 and the second conduction elastic sheet 122, quickly realizing the disconnection of the circuit.

[0069] Optionally, referring to Figure 5 and Figure 6 , the aerosol generating device 1 of the present invention further includes: a supporting part 22. Optionally, the supporting part 22 extends along the first direction ( Figure 6 shown as the X direction in the figure) and is used to hold the aerosol forming substrate 2 to limit the movement of the aerosol forming substrate 2 in the first direction. The supporting part 22 is connected to the sliding part 20, and the sliding part 20 can drive the supporting part 22 to move. The outer shape of the supporting part 22 matches that of the heating chamber 11 and can be freely inserted into the heating chamber 11.

[0070] Preferably, the supporting part 22 has a stop 221 (see Figure 5 ) to limit the aerosol forming substrate 2 from sliding out of the supporting part 22 towards the inlet 111. The stop 221 can also drive the aerosol forming substrate 2 to move out of the heating chamber 11 when the supporting part 22 moves out of the heating chamber 11, so as to reduce the residue in the heating chamber 11. Preferably, the stop 221 is a "C"-shaped stop to provide a flow path for the aerosol in the first direction.

[0071] Referring to Figure 7, at the first position, driven by the sliding part 20, at least a part of the supporting part 22 is located in the heating chamber 11; Refer to Figure 8 , at the second position, the sliding part 20 and the main body 10 define a notch 112 in the first direction, and the aerosol-forming substrate 2 can be placed on the supporting part 22 through the notch 112, and the supporting part 22 is located at the notch 112.

[0072] That is, during the sliding of the sliding part 20 in the first direction, the supporting part 22 can be driven to move synchronously. Subsequently, the aerosol-forming substrate 2 placed in the supporting part 22 can reciprocate synchronously with the sliding part 20 in the first direction; it is beneficial to extract the aerosol-forming substrate 2 from the heating chamber 11, prevent the aerosol-forming substrate 2 from adhering to the side wall of the heating chamber 11 due to substances such as tar generated during the suction process, and keep the aerosol generating device 1 clean. In some embodiments, regardless of whether it is in the first position or the second position, the circuit between the heating element and the power supply is in a conducting state, and the aerosol-forming substrate 2 is heated in the heating chamber 11 by controlling the switch.

[0073] Optionally, a guiding groove extending in the first direction is provided on the base 13 at the notch 112, and the guiding groove and the inlet 111 of the heating chamber 11 are oppositely arranged in the first direction. The supporting part 22 is arranged in the guiding groove and can slide into the heating chamber 11 along the guiding groove.

[0074] Continue to refer to Figure 5 and Figure 6 , a slot 23 is provided at the bottom of the supporting part 22, and an elastic pressing part 30 is provided on the base 13 at the notch 112. During the movement of the sliding part 20 in the first direction, the elastic pressing part 30 can be pressed. At the second position, the elastic pressing part 30 can contact the aerosol-forming substrate 2 at the slot 23 and move towards the aerosol-forming substrate 2, so that the aerosol-forming substrate 2 is separated from the supporting part 22.

[0075] When the aerosol-forming substrate 2 is placed in the heating chamber 11 and completed heating, when the sliding part 20 drives the supporting part 22 to retreat to the second position, the elastic pressing part 30 moves towards the aerosol-forming substrate 2 at the slot 23, that is, upwards ( Figure 8 as shown by the E direction in the figure) to lift the aerosol-forming substrate 2, so that the aerosol-forming substrate 2 is separated from the supporting part 22, and the aerosol-forming substrate 2 is thrown out. While avoiding the adhesion of the aerosol-forming substrate 2 to the inside of the heating chamber 11, it also drives the aerosol-forming substrate 2 to retreat from the heating chamber 11 and automatically eject from the supporting part 22. The user does not need to contact the aerosol-forming substrate 2 with residual heat to prevent scalding and affecting the user experience.

[0076] Refer to Figure 8, in this embodiment, the elastic pressing part 30 includes a torsion spring shaft 31, a torsion spring 32 and a top plate 33. The torsion spring shaft 31 is installed in the main body 10. The top plate 33 is rotatably connected to the torsion spring shaft 31 through the torsion spring 32. The top plate 33 can contact the aerosol forming matrix 2 at the slot 23 and move towards the aerosol forming matrix 2. Among them, the top plate 33 is sleeved on the torsion spring shaft 31. One of the two legs of the torsion spring 32 abuts against the main body 10, and the other abuts against the top plate 33. When the top plate 33 is pressed by an external force, the top plate 33 can rotate around the torsion spring shaft 31. When there is no external force acting on the top plate 33, the top plate 33 rotates around the torsion spring shaft 31 to reset, so that the aerosol forming matrix 2 automatically pops out of the supporting part 22.

[0077] That is, due to the acting force of the lower torsion spring 32, the top plate 33 always has a tendency to push upward; the slot 23 at the bottom of the supporting part 22 matches the top plate 33. When the sliding cover 24 drives the supporting part 22 to move forward ( Figure 4 the forward direction is shown by the C direction in the figure), the top plate 33 is pressed downward, and the aerosol forming matrix 2 is reset in the supporting part 22 and sent into the heating chamber 11. When the sliding part 20 drives the supporting part 22 to move backward ( Figure 2 the backward direction is shown by the B direction in the figure), the top plate 33 can freely push upward. The top plate 33 enters the slot 23 at the bottom of the supporting part 22, so as to push against the aerosol forming matrix 2 and throw the aerosol forming matrix 2 out.

[0078] Optionally, referring to Figure 7 , the top plate 33 has a ramp boss 34. The ramp boss 34 includes an inclined surface. The ramp boss 34 protrudes outward towards the aerosol forming matrix 2. During the process of the sliding part 20 sliding between the second position and the first position, the inclined surface can be pressed.

[0079] Among them, the number of inclined surfaces of the ramp boss 34 is not limited, which can facilitate the pressing of the top plate 33 during the process of the sliding part 20 sliding between the second position and the first position. Optionally, the ramp boss 34 includes a first inclined surface 331 and a second inclined surface 332 located on opposite sides of the top plate 33 along the first direction ( Figure 7 shown by the X direction in the figure). During the process of the sliding part 20 moving from the second position to the first position (refer to Figure 8 and Figure 9 ), the top plate 33 can be pressed at the first inclined surface 331. During the process of the sliding part 20 moving from the first position to the second position (refer to Figure 7 ), the top plate 33 can be pressed at the second inclined surface 332.

[0080] Thus, the aerosol-forming substrate 2 is placed in the support part 22. When the sliding part 20 drives the support part 22 to move forward (closing the sliding part 20), the support part 22 transmits the conversion through the ramp boss 34 on the top plate 33, presses the first inclined surface 331 to press down the top plate 33, and the aerosol-forming substrate 2 is completely reset ( Figure 9 ), and smoothly inserted into the heating chamber 11 together with the support part 22 ( Figure 7 ). The support part 22 passes over the top plate 33, and the top plate 33 resets.

[0081] After the suction is completed, when the sliding part 20 drives the support part 22 to move backward (opening the sliding part 20), the support part 22 transmits the conversion through the ramp boss 34 on the top plate 33, presses the second inclined surface 332 to press down the top plate 33. As the sliding part 20 continues to move backward, the top plate 33 resets upward and is inserted into the slot 23 at the bottom of the support part 22, acting on the aerosol-forming substrate 2. The horizontal movement of the sliding part 20 and the upward movement of the top plate 33 occur simultaneously.
