The heating device 12 may include a heating element 121, and when the housing tube 11 and the heating device 12 are in the first position, the heating element 121 extends into the housing tube 11 and contacts the aerosol-forming substrate 17, and when the heating device 12 is energized, the heating element 121 heats and heats the contact aerosol-forming substrate 17 to atomize it.
In one embodiment, the outer cover 15 is partially disposed in the base 14, the other portion is disposed in the upper cover 16, and one end of the upper cover 16 near the aerosol-forming substrate 17 has a communication hole 21, one end of the housing tube 11 near the aerosol-forming substrate 17 is fixed to one end of the upper cover 16 near the aerosol-forming substrate 17, and the communication hole 21 is in communication with the housing space of the housing tube 11. In an embodiment, the upper cover 16 includes a top wall 161 abutting against the outer side of the accommodating tube 11 and perpendicular to the axial direction of the accommodating tube, and a sleeve portion 162 sleeved on the outer side of the housing 15 and perpendicular to the top wall 161, wherein the top wall 161 forms a communication hole 21 accommodating the accommodating tube 11 and communicating with the accommodating space of the accommodating tube 11, and wherein the top wall 161 and the accommodating tube 11 can be connected together by, for example, clamping. In an embodiment, the upper cover 16 may be integrally formed with the housing tube 11, and of course, when the upper cover 16 is integrally formed with the housing tube 11, the top wall 161 is connected to the housing tube 11, and the communication hole 21 serves as a housing space of the housing tube 11 to house the aerosol-forming substrate 17.
In one embodiment, the base 14 is used for accommodating the power supply device 13, and when the accommodating tube 11 and the heating device 12 are in the first position, the upper cover 16 abuts against the base 14 to form a space for accommodating the heating device 12. The base 14 is connected with the outer cover 15, which may be integrally formed, as shown in fig. 1, for example, a second protrusion 151 facing the base 14 is provided at a position where the outer cover 15 is connected with the base 14, a clamping groove 141 is provided at a position where the outer cover 15 is accommodated in the base 14, the outer cover 15 is partially inserted into the base 14, and the second protrusion 151 on the outer cover 15 is clamped in the clamping groove 141 on the base 14, so as to fix the outer cover 15 in the base 14.
In an embodiment, the accommodating tube 11 can drive the heating device 12 to move along a first position and a second position, and in the first position, the first clamping position 152 of the outer cover 15 is clamped with the upper clamping position 153 of the upper cover 16, and the conductive portion 122 on the heating device 12 is contacted with the electrode 131 on the power supply device 13 to supply power.

In an embodiment, to move the accommodating tube 11 and the heating device 12 along the first position to the second position, an upward force needs to be applied to the upper cover 16 (i.e. the upper cover 16 is pulled along the direction of the aerosol-forming substrate 17), and since the upper cover 16 is connected to or integrally formed with the accommodating tube 11, the upper cover 16 drives the accommodating tube 11 to move upward, and the accommodating tube 11 and the heating device 12 are engaged with each other through the first protrusion 111 and the engagement hole 124 at the flange 123, when the accommodating tube 11 moves upward to the second position, the heating device 12 moves upward to the second position along the sliding track formed by the second portion of the housing 15 until the abutment portion 125 on the heating device 12 abuts against the stop table 154 on the housing 15. In this way, it is possible to stop heating of the heating means 12 without changing the aerosol-forming substrate 17, thereby preventing breakage of the aerosol-forming substrate 17.

In an embodiment, if the aerosol-forming substrate 17 needs to be replaced, the upper cover 16 can also drive the accommodating tube 11 to move to the third position (as shown in fig. 3) to separate the accommodating tube 11 from the heating device 12, and further drive the aerosol-forming substrate 17 to separate from the heating device 12 through the accommodating tube 11, so as to prevent tobacco shreds of the aerosol-forming substrate 17 from remaining on the heating device 12 when the aerosol-forming substrate 17 is separated from the heating device 12 when the aerosol-forming substrate 17 is directly pulled. In an embodiment, when the accommodating tube 11 and the heating device 12 are in the second position, the upward force is continuously applied to the upper cover, at this time, the abutting portion 125 on the heating device 12 abuts against the stop table 154 on the housing 15, so that the first protrusion 111 and the engaging hole 124 at the flange 123 are separated, and the heating device 12 is further separated from the accommodating tube 11, so that the aerosol-forming substrate 17 is separated from the heating device 12, and at this time, when the aerosol-forming substrate 17 is replaced, only the aerosol-forming substrate 17 needs to be pulled out from the accommodating tube 11, so as to avoid the aerosol-forming substrate 17 remaining on the heating device 12.

Further, the housing tube 11 forms a cylindrical housing chamber 116 for housing the aerosol-forming substrate 17, and the through hole 115 communicates with the housing chamber 116 and has a smaller cross-sectional area than the housing chamber 116. The bottom wall 114 urges the aerosol-forming substrate 17 to move with the receiving tube 11 during the movement of the receiving tube 11 from the second position (fig. 2) to the third position (fig. 3).

The fixing seat 126 further includes a receiving seat 64, where the receiving seat 64 is formed by two semi-cylindrical cylinders that are engaged with each other, and the fixing member 62 and the sealing member 65 are fixed on a side of the receiving seat 64 protruding from the heating element 121. The sleeve 66 is sleeved outside the accommodating seat 64 on one side of the accommodating seat 64 protruding the heating element 121. Further, the edge of the sleeve 66 may act as an abutment 125. The flange 123 for the card-receiving receptacle 11 is integral with the sleeve 66 and the conductive portion 122 of the heating device 12 is located on a surface of the circuit board 63 remote from the heating element 121.
Specifically, the conductive portion 122 of the heating device 12 is located on a surface of the circuit board 63 exposed from the accommodating seat 64. When the conductive part 122 is energized in contact with the electrode 131 on the power supply device 13, the conductive line and the heat generating line are energized further by the first connection terminal and the second connection terminal connected to the wiring board 63, so that the heat generating line generates heat and heats the aerosol-forming substrate.
In one embodiment, the flange 123 for receiving the receiving tube 11 wraps around a portion of the receiving tube 11, and as shown in fig. 5, only a partial position of the heating device 12 in cross section has the flange 123. The end of the accommodating tube 11 connected with the heating device 12 is provided with a pressing part 112 which is abutted against the heating device 12 and corresponds to the position of the flange 123, and the diameter of the pressing part 112 is smaller than that of the rest position of the accommodating tube 11. When the receiving tube 11 is inserted into the flange 123 and the pressing portion 112 is abutted against the heating device 12, the pressing portion 112 is not in contact with the flange 123 of the heating device 12 and the heating element of the heating device 12. As shown in fig. 4, the pressing portion 112 corresponds to the flange 123, and does not completely surround the accommodating tube 11, that is, the pressing portion 112 is not in a circular ring shape with a closed periphery, so that when the pressing portion 112 is abutted against the heating device 12, an air flow channel communicating with the interior of the accommodating tube 11 is formed at a position where the pressing portion 112 is not provided at one end of the accommodating tube 11 connected to the heating device 12, and when the air is sucked, external air enters into the aerosol forming substrate in the accommodating tube 11 through the air flow channel, and further, the smoke is emitted outwards.
According to the aerosol generating device provided by the invention, the heating device is driven by the accommodating pipe to move along the first position to the second position so as to separate the heating device from the power supply device, and then the heating device is moved from the second position to the third position so as to separate the aerosol forming substrate from the heating device, thereby avoiding the tobacco shreds of the aerosol forming substrate from remaining on the heating device when the aerosol forming substrate is directly pulled out.
The foregoing is only the embodiments of the present invention, and therefore, the patent scope of the invention is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present invention and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the invention.
