As shown in fig. 5, 6 and 8, in one embodiment, the bracket assembly 30 includes an inner tube 32 and a base 33, the inner tube 32 has a receiving cavity 321 therein, at least a portion of the base 33 and the heating tube 40 are disposed in the receiving cavity 321, and the base 33 is connected to an end of the inner tube 32 away from the opening 411 in a sealing manner, for example, a sealing ring may be used for sealing connection. One end of the heating tube 40 near the opening 411 abuts against the inner tube 32, and one end of the heating tube 40 far away from the opening 411 abuts against the base 33, so that the heating tube 40 is mounted inside the bracket assembly 30. The base 33 is provided with a through hole communicating the first closed chamber 511 and the accommodating chamber 41.

Further, the bracket assembly 30 further includes an outer tube 34, wherein the outer tube 34 is sleeved on the outer periphery of the inner tube 32 and is connected with the inner tube 32, and as shown in fig. 9, an air inlet channel 31 is formed between the outer tube 34 and the inner tube 32. Specifically, the first sealing portion 521 of the first seal 52 and the second sealing portion 531 of the second seal 53 each encircle the outer periphery of the outer tube 34 and are sealingly connected to the side wall of the outer tube 34.

In one embodiment, the outer periphery of the outer tube 34 is provided with a first clamping portion 341, the mounting frame 60 has a second clamping portion 62, and the first clamping portion 341 is clamped with the second clamping portion 62. Of course, in other embodiments, the bracket assembly 30 is not limited to the above configuration, and may be other modified configurations.

In one embodiment, as shown in fig. 5, the heating non-combustion apparatus further includes a nozzle holder 90, where the nozzle holder 90 has an opening 91, and the nozzle holder 90 is mounted on the housing 20, and the nozzle holder 90 may be detachably connected to the housing 20, for example, may be snap-connected to the housing 20, and the opening 91 of the nozzle holder 90, the insertion hole 5321 of the second sealing member 53, and the opening 411 of the accommodating cavity 41 may be sequentially disposed opposite to each other, that is, the three may be sequentially aligned along a straight line, so that the aerosol base structure 10 may be sequentially inserted into the accommodating cavity 41 through the opening 91, the insertion hole 5321, and the opening 411. Further, a clamping member 100 may be disposed within the aperture 91, and an inner diameter of the clamping member 100 may be slightly smaller than an outer diameter of the aerosol base structure 10, such that the clamping member 100 may clamp the aerosol base structure 10.

To ensure that as little heat as possible is transferred from the heating tube 40 to the seal assembly 50 to prevent failure of the seal assembly 50, the bracket assembly 30 may be made of a material having a low thermal conductivity. For example, the inner tube 32 and the base 33 may be made of polyether-ether-ketone (PEEK), and the outer tube 34 may be made of at least one of PEEK, polyaryletherketone (PAEK), polyphenylene sulfone resin (Polyphenylene sulfone resins PPSU), nylon, polytetrafluoroethylene (PTFE), polyvinylidene fluoride (polyvinylidene difluoride PVDF), polysulfone (Polysulfone PSU), liquid crystal polymer (Liquid Crystal Polymer LCP), fluororubber (fluororubber FKM), polyimide (Polyimide PI), and thermoplastic Polyimide (thermoplastic Polyimide TPI). Experiments show that the working temperature of the heating pipe 40 in the bracket assembly 30 can reach 300 ℃, the temperature of the sealing ring in the bracket assembly 30 can reach 200 ℃, and the temperature of the sealing assembly 50 is only about 100 ℃ because the bracket assembly 30 is made of a material with low heat conductivity, so that the aging speed of the sealing assembly 50 can be greatly reduced, and liquid leakage is prevented.

The foregoing description of the application has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the application pertains, based on the idea of the application.
