Referring to fig. 1 and 2, the present application provides an aerosol-generating device 100, the aerosol-generating device 100 comprising a housing 1, a heating assembly 2 and a mount 3. Wherein the heating component 2 is used for atomizing tobacco tar and generating aerosol for a user to inhale. The housing 1 is used for providing a mounting space for the heating assembly 2, the mounting member 3 is located inside the housing 1, and the mounting member 3 is used for enhancing the connection strength between the housing 1 and the heating assembly 2.

The housing 1 is substantially cylindrical, and the interior of the housing 1 is hollow to form a housing chamber 111.

The heating assembly 2 is used to heat an aerosol product, including but not limited to tobacco tar, to produce an aerosol. The heating assembly 2 is accommodated in the accommodating chamber 111. The structure of the heating element 2 is known in the art and will not be described in detail herein.

The mounting member 3 is substantially strip-shaped, and one of the mounting member 3 and the mounting groove 41 is provided on the outer surface of the heating element 2, and the other is provided on the inner surface of the housing 1. As in the embodiment shown in fig. 2-6, the mounting member 3 is disposed on the outer surface of the heating element 2, and the mounting groove 41 for receiving the mounting member 3 is disposed on the inner surface of the housing 1. In other possible embodiments, the mounting member 3 is provided on the inner surface of the housing 1, and the mounting groove 41 is provided on the outer surface of the heating element 2.

Referring to fig. 3 to 5, when the heating assembly 2 is received in the receiving chamber 111, the mounting member 3 is received in the mounting groove 41. The outer surface of the heating element 2 is not in contact with the inner surface of the housing 1 by the fitting of the fitting 3 with the fitting groove 41, i.e. there is a gap between the outer surface of the heating element 2 and the inner surface of the housing 1. Thereby increasing the thermal resistance between the housing 1 and the heating assembly 2. Burn-out of the housing 1 of the aerosol-generating device 100 may be avoided, while heat loss from the heating assembly 2 may also be reduced.

Referring to fig. 3, in some embodiments, at least two protrusions 4 are disposed on the inner surface of the housing or the outer surface of the heating element 2, and the space between the two protrusions 4 forms the mounting groove 41.

In some embodiments, when the mounting member 3 protrudes from the heating element 2 and the mounting groove 41 is formed by at least two protruding strips 4 and the heating element 2 is in a smooth state (no protruding structure), when the mounting member 3 is accommodated in the mounting groove 41, a gap is provided between the inner surface of the housing 1 and the outer surface of the heating element 2.

Referring to fig. 3, in some embodiments, the height of the mounting member 3 protruding from the heating element 2 is greater than the depth of the mounting groove 41, i.e., the height of the mounting member 3 is greater than the depth of the mounting groove 41. Therefore, when the mounting member 3 is accommodated in the mounting groove 41, a large gap can be formed between the outer surface of the heating element 2 and the inner surface of the housing 1, and contact heat transfer between the heating element 2 and the housing 1 can be avoided.

In some embodiments, the mounting groove 41 is formed directly by an inner surface recess of the housing 1, or the mounting groove 41 is formed directly by an outer surface recess of the heating assembly 2. Therefore, when the mounting member 3 protrudes above the heating element 2 by a height greater than the depth of the mounting groove 41, a gap can be formed between the outer surface of the heating element 2 and the inner surface of the housing 1, and contact heat transfer between the heating element 2 and the housing 1 can be avoided.

Referring to fig. 2, in some embodiments, the mounting member 3 includes a plurality of mounting bars 31, each of the mounting bars 31 is in a bar shape, and each of the mounting bars 31 is disposed at intervals along the extending direction of the mounting groove 41. Therefore, the contact area of the mounting member 3 with the side wall of the mounting groove 41 can be reduced as compared with the single integral mounting bar 31, the mounting bars 31 being arranged at intervals. Thereby further reducing the amount of heat transferred from the heating assembly 2 to the housing 1 via the mounting 3.

Referring to fig. 4 and 6, in some embodiments, the protruding strip 4 is provided with an opening 42, and when the mounting member 3 is received in the mounting groove 41, the opening 42 exposes at least a portion of the mounting member 3. By the provision of this opening 42, the contact area of the mount 3 with the side wall of the mounting groove 41 can be reduced, thereby further reducing the amount of heat transferred from the heating assembly 2 to the housing 1 through the mount 3.

The opening 42 may be provided in either one of the two protrusions 4 forming one mounting groove 41, or the opening 42 may be provided in both of the two protrusions 4 forming one mounting groove 41.

It will be appreciated that when the two protruding strips 4 forming one mounting groove 41 are provided with the openings 42, the openings 42 on the two protruding strips 4 may be arranged in a staggered manner, and the openings 42 on the two protruding strips 4 may be arranged in parallel. Referring to the embodiment of fig. 6, when the openings 42 on the two protruding strips 4 are arranged in parallel, the mounting groove 41 is formed by a plurality of discontinuous groove segments.

Referring to fig. 2, in some embodiments, at least one end of the housing 1 along the extending direction of the mounting groove 41 is provided with a mounting hole 112, and the mounting hole 112 communicates with the receiving chamber 111. The mounting member 3 extends in the extending direction of the mounting groove 41, and thus, the heating assembly 2 can be placed into the accommodating chamber 111 through the mounting hole 112. And, when the heating assembly 2 is accommodated in the accommodating chamber 111, the mounting member 3 is accommodated in the mounting groove 41.

In some embodiments, the housing 1 is provided with mounting holes 112 at both ends in the extending direction of the mounting groove 41.

The method of assembling the aerosol-generating device 100 is generally as follows: referring to fig. 2, one end of the heating element 2 is aligned with the mounting hole 112, then the heating element 2 is rotated to align the mounting member 3 with the mounting hole 112, and finally the heating element 2 is pushed into the accommodating cavity 111, so that the heating element 2 can be installed into the accommodating cavity 111, and the mounting member 3 is accommodated in the mounting groove 41.

Referring to fig. 3, in some embodiments, a plurality of mounting grooves 41 are provided, and each mounting groove 41 is disposed at intervals along the circumferential direction of the housing 1. The number of the mounting pieces 3 is equal to the number of the mounting grooves 41, and the mounting pieces 3 are arranged in one-to-one correspondence with the mounting grooves 41. When the heating assembly 2 is accommodated in the accommodating chamber 111, each mounting member 3 is positioned in the corresponding mounting groove 41. The plurality of mounting grooves 41 can increase the stability of the heating element 2 and reduce the probability of the heating element 2 falling out of the accommodating chamber 111.

In some embodiments, the mounting 3 may be an interference fit or a clearance fit or a transition fit with the mounting groove 41.

In some embodiments, the aerosol-generating device 100 further comprises a thermal insulation member (not shown) that is wrapped around the outer surface of the heating element 2 to reduce the heat radiated outward by the heating element 2 and reduce the heat loss from the heating element 2.

In some embodiments, there is a gap between the outer surface of the insulation and the inner surface of the housing 1. I.e. the outer surface of the heat shield is not in contact with the inner surface of the housing 1, heat transfer from the heating assembly 2 to the housing 1 through the heat shield is avoided.

For the heat insulating member, the material may be glass fiber, asbestos or silicate, and the heat insulating member made of glass fiber, asbestos or silicate has a good heat insulating effect, so that the heat radiated from the heating element 2 can be reduced.

The aerosol-generating device 100 of an embodiment of the application comprises a housing 1, a heating assembly 2 and a mounting part 3, the housing 1 being provided with a receiving cavity 111, the heating assembly 2 being adapted to heat tobacco tar to generate an aerosol. The mounting 3 is attached to the outer surface of the heating element 2 or the inner surface of the housing 1. When the mounting member 3 is attached to the outer surface of the heating assembly 2, the inner surface of the housing 1 is provided with a mounting groove 41 for receiving the mounting member 3. By the cooperation of the mounting piece and the mounting groove, a gap is formed between the outer surface of the heating component and the inner surface of the shell. Thereby increasing the thermal resistance between the housing 1 and the heating element 2, avoiding scalding of the housing 1 of the aerosol-generating device 100, while reducing heat loss from the heating element 2.
