[0002] In recent years, the impact of traditional cigarettes on health and the environment has gradually attracted the attention of countries around the world. Tobacco manufacturers are committed to providing consumers with less harmful tobacco products. As a new form of tobacco consumption, low-temperature heat-not-burn tobacco products are gradually gaining popularity in the market and are increasingly being accepted by cigarette consumers in most countries.

[0056] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0057] refer to Figures 1 to 4 The present invention provides an aerosol generating device 1, comprising: a main body 10, the main body 10 comprises a shell, the main body 10 has a first direction ( Figure 1 and Figure 2 The heating chamber 11 extends in the X direction, and an aerosol passage is formed in the heating chamber 11. The heating chamber 11 has an inlet 111 for the aerosol-forming matrix 2 to enter and an air flow outlet 115 (refer to the following Figure 8 Optionally, along the first direction, the inlet 111 and the airflow outlet 115 of the aerosol channel (refer to the following Figure 8 ) are located on opposite sides of the heating chamber 11; optionally, along the first direction, the inlet 111 and the airflow outlet 115 of the aerosol channel are spaced apart.

[0058] The invention also includes: a sliding part 20, which is slidably mounted on the main body 10 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, with reference to Figure 3 and Figure 4 In the first position, the sliding portion 20 is in a retracted state, and optionally, the inlet 111 is covered by the sliding portion 20, and the circuit between the heating element and the power supply is in a conducting state; Figure 1 and Figure 2 In the second position, the sliding portion 20 is in an open state, the inlet 111 is opened, the aerosol-forming substrate 2 can be placed into the heating chamber 11 through the inlet 111, and the circuit between the heating element and the power supply is in an open state.

[0059] Optionally, refer to Figure 2 , Figures 4 to 6, the main body 10 is provided with a first sliding member 40, and the sliding part 20 is provided with a second sliding member 41, the second sliding member 41 and the first sliding member 40 cooperate with each other, and the second sliding member 41 and the first sliding member 40 can produce relative sliding in the first direction. There is no restriction on the type of sliding member between the sliding part 20 and the main body 10, and there is no restriction on the way of cooperation between the sliding members, as long as they can produce relative sliding. Optionally, one of the first sliding member 40 and the second sliding member 41 is a slide rail, and the other is a slide groove. In this embodiment, the first sliding member 40 is a slide rail, and the second sliding member 41 is a slide groove. In other embodiments, it can be other types of sliding members, such as a guide rod and a sliding sleeve.

[0060] With the above technical solution, when the aerosol-forming substrate 2 needs to be placed, the sliding portion 20 slides from the first position to the second position ( Figure 1 and Figure 2 The direction B in the figure shows the sliding direction), the entrance 111 is opened, and the aerosol-forming matrix 2 enters the heating chamber 11 through the entrance 111. At this time, the circuit between the heating element and the power supply is in an open circuit state. No matter how the aerosol generating device 1 is started, the heating element cannot perform heating work, that is, it will not consume the power of the power supply.

[0061] When the aerosol-forming substrate 2 is loaded into the heating chamber 11, the sliding portion 20 slides from the second position to the first position ( Figure 4 The direction C in the middle shows the sliding direction), the inlet 111 is covered by the sliding portion 20. At this time, the circuit between the heating element and the power supply is in a conducting state, the power supply can be started to enable the heating element to perform heating work, the power supply supplies power to the circuit in the aerosol generating device, the heating element is used to heat the aerosol-forming matrix 2, and the generated aerosol flows out from the airflow outlet of the aerosol channel for the user to inhale.

[0062] This arrangement can prevent the aerosol generating device 1 from being accidentally started and improve the power endurance of the aerosol generating device 1; the sliding of the sliding part 20 between the first position and the second position solves the problem of power consumption caused by accidental triggering when no load is applied, and the structure is simple and the cost is low.

[0063] In other words, the heating chamber 11 and the sliding portion 20 of the present invention are distributed along the first direction, which is the overall extension direction of the aerosol generating device 1. After the sliding portion 20 is opened on the side of the aerosol generating device 1, the aerosol-forming substrate 2 is placed at the notch 112 described later, and is placed into the heating chamber 11 through the inlet 111.

[0064] Optionally, refer to Figure 2 and Figure 4 The main body 10 of the present invention is provided with a first conductive area 12, and the sliding portion 20 is provided with a second conductive area 21. In the first position, the first conductive area 12 and the second conductive area 21 are in contact (such as Figure 4 As shown), the circuit is in a conducting state; in the second position, the first conducting area 12 and the second conducting area 21 are separated (as shown Figure 2 As shown), the circuit is in an open circuit state.

[0065] Among them, the position of the first conductive area 12 on the main body 10 is not restricted, the position of the second conductive area 21 on the sliding part 20 is not restricted, and the materials of the first conductive area 12 and the second conductive area 21 are not restricted; in addition, the form of contact between the first conductive area 12 and the second conductive area 21 is not restricted, and it can be an electrical connection to realize that the circuit is in a conductive state; it can also be a mechanical connection, and the circuit is in a conductive state by controlling the switch, satisfying the following conditions: in the first position, the first conductive area 12 and the second conductive area 21 are in contact, and the circuit is in a conductive state; in the second position, the first conductive area 12 and the second conductive area 21 are separated, and the circuit is in an open circuit state.

[0066] Specifically, in this embodiment, reference Figure 1 , the first conductive region 12 includes a first conductive spring 121 and a second conductive spring 122 in an open circuit state, the first conductive spring 121 and the second conductive spring 122 are respectively connected to the positive electrode and the negative electrode of the power supply; optionally, the first conductive spring 121 and the second conductive spring 122 are connected along the second direction ( Figure 1 The first conductive region 12 is made of metal. In some embodiments, the first conductive spring 121 and the second conductive spring 122 are distributed on the main body 10 in other forms, such as being spaced apart along the first direction, being staggered in the second direction, etc.

[0067] refer to Figure 5 , the second conductive area 21 includes a first contact area 211 and a second contact area 212 in a conductive state; optionally, the second conductive area 21 is in an arc shape as a whole, and the first contact area 211 and the second contact area 212 are located at the first and last ends of the second conductive area 21. In the first position, the first contact area 211 is in contact with the first conductive spring 121, and the second contact area 212 is in contact with the second conductive spring 122; in the second position, the first contact area 211 is separated from the first conductive spring 121, and the second contact area 212 is separated from the second conductive spring 122. Optionally, the second conductive area 21 is formed by gold-plated metal, LDS (Laser Direct Structuring, referred to as laser direct structuring) process or other processes for achieving conduction on the left and right sides.

[0068] refer to Figure 2 and Figure 3 The main body 10 is provided with a limiter 14 for limiting 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 a second position. A notch 112 is provided between the limiter 14 and the heating chamber 11. The aerosol-forming substrate 2 can be placed and removed at the notch 112. The first conductive area 12 is provided on the base 13 at the notch 112.

[0069] The first conductive spring piece 121 and / or the second conductive spring piece 122 at least partially extends out of the base 13 and can be moved along the third direction ( Figure 2 The first conductive spring 121 and the second conductive spring 122 are pressed to deform, and the third direction is perpendicular to the first direction. In this embodiment, the first conductive spring 121 and the second conductive spring 122 are both extended out of the base 13. Since the first conductive spring 121 and the second conductive spring 122 can be pressed to deform, it is beneficial for the first contact area 211 to separate from the first conductive spring 121, and the second contact area 212 to separate from the second conductive spring 122, so as to quickly disconnect the circuit.

[0070] Optionally, refer to Figure 5 and Figure 6 The aerosol generating device 1 of the present invention further comprises: a supporting portion 22, optionally, the supporting portion 22 is arranged along the first direction ( Figure 6 The support portion 22 extends in the X direction (shown in the middle X direction) to hold the aerosol-forming substrate 2 to limit the movement of the aerosol-forming substrate 2 in the first direction, and the support portion 22 is connected to the sliding portion 20, and the sliding portion 20 can drive the support portion 22 to move. The shape of the support portion 22 matches the heating chamber 11 and can be freely inserted into the heating chamber 11.

[0071] Preferably, the support portion 22 has a stopper 221 (see Figure 5 ), so as to limit the aerosol-forming substrate 2 from sliding out of the support portion 22 toward the inlet 111. The stopper 221 can also drive the aerosol-forming substrate 2 to move out of the heating chamber 11 when the support portion 22 moves out of the heating chamber 11, so as to reduce the residue in the heating chamber 11. Preferably, the stopper 221 is a "C"-shaped stopper to provide a flow path for the aerosol in the first direction.

[0072] refer to Figure 7 , in the first position, driven by the sliding portion 20, at least a portion of the supporting portion 22 is located in the heating chamber 11; Figure 8In the second position, the sliding portion 20 and the main body 10 define a gap 112 in the first direction, and the aerosol-forming substrate 2 can be placed on the supporting portion 22 through the gap 112 , and the supporting portion 22 is located at the gap 112 .

[0073] That is, the sliding portion 20 can drive the support portion 22 to move synchronously during the sliding process in the first direction, and then the aerosol-forming substrate 2 placed in the support portion 22 can reciprocate synchronously with the sliding portion 20 in the first direction, which is conducive to extracting the aerosol-forming substrate 2 from the heating chamber 11 and keeping the aerosol-generating device 1 clean. In some embodiments, whether 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 control switch.

[0074] Optionally, a guide groove extending along the first direction is provided on the base 13 at the notch 112, and the guide groove is arranged opposite to the entrance 111 of the heating chamber 11 along the first direction. The support portion 22 is arranged in the guide groove and can slide into the heating chamber 11 along the guide groove.

[0075] Continue to refer Figure 5 and Figure 6 A groove 23 is provided at the bottom of the support portion 22, and an elastic pressing portion 30 is provided on the base 13 at the notch 112. During the movement of the sliding portion 20 along the first direction, the elastic pressing portion 30 can be pressed. In the second position, the elastic pressing portion 30 can contact the aerosol-forming substrate 2 at the groove 23 and move toward the aerosol-forming substrate 2 to separate the aerosol-forming substrate 2 from the support portion 22.

[0076] When the aerosol-forming substrate 2 is placed in the heating chamber 11 and heated, the sliding portion 20 drives the supporting portion 22 to retreat to the second position, and the elastic pressing portion 30 moves toward the aerosol-forming substrate 2 at the slot 23, that is, upward ( Figure 8 The aerosol-forming matrix 2 is lifted up (as shown in the direction E in the middle), so that the aerosol-forming matrix 2 is separated from the supporting portion 22, and the aerosol-forming matrix 2 is thrown out, which prevents the aerosol-forming matrix 2 from adhering to the heating chamber 11, and also drives the aerosol-forming matrix 2 to exit the heating chamber 11 and automatically pop out of the supporting portion 22. The user does not need to touch the aerosol-forming matrix 2 with residual heat, thereby preventing burns from affecting the user experience.

[0077] refer to Figure 8In this embodiment, the elastic pressing portion 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 substrate 2 at the slot 23 and move toward the aerosol-forming substrate 2. 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 substrate 2 automatically pops out of the supporting portion 22.

[0078] That is, due to the force of the torsion spring 32 below, the top plate 33 has a tendency to push upward; the bottom slot 23 of the support part 22 matches the top plate 33. When the sliding cover 24 drives the support part 22 forward ( Figure 4 When the sliding part 20 drives the supporting part 22 to move backward (the direction C in the figure shows the forward direction), the top plate 33 is pressed downward, and the aerosol-forming substrate 2 returns to its original position in the supporting part 22 and is sent into the heating chamber 11. Figure 2 When the top plate 33 is pushed upward freely, the top plate 33 enters the groove 23 at the bottom of the support portion 22, and then pushes onto the aerosol-forming substrate 2 to eject the aerosol-forming substrate 2.

[0079] Optionally, refer to Figure 7 The top plate 33 has a sloped boss 34, and the sloped boss 34 includes a sloped surface. The sloped boss 34 protrudes toward the aerosol-forming substrate 2, and the sloped surface can be pressed during the sliding of the sliding portion 20 between the second position and the first position.

[0080] The number of inclined surfaces of the sloped boss 34 is not limited, and it is possible to facilitate the top plate 33 to be pressed during the sliding of the sliding part 20 between the second position and the first position. Figure 7 The first inclined surface 331 and the second inclined surface 332 are located on opposite sides of the top plate 33, and during the movement of the sliding portion 20 from the second position to the first position (refer to Figure 8 and Fig. 9 ), the top plate 33 can be pressed at the first inclined surface 331, and during the movement of the sliding portion 20 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.

[0081] Thus, the aerosol-forming substrate 2 is placed in the support portion 22. When the sliding portion 20 drives the support portion 22 forward (closing the sliding portion 20), the support portion 22 transmits the conversion through the slope boss 34 on the top plate 33, pressing the first slope 331 to press the top plate 33 down, and the aerosol-forming substrate 2 is completely returned to its original position ( Fig. 9 ), and smoothly inserted into the heating chamber 11 together with the support portion 22 ( Figure 7 ), the support portion 22 passes over the top plate 33, and the top plate 33 is reset.
