The first bracket 211 and the second bracket 212 are fixedly connected together along a radial direction, specifically, one of the first bracket 211 and the second bracket 212 is provided with a clamping groove, the other one of the first bracket 211 and the second bracket 212 is provided with a buckle, and the first bracket 211 and the second bracket 212 are fixedly connected together through the clamping groove and the buckle. Alternatively, the first bracket 211 and the second bracket 212 may be fixedly connected together by any other feasible means, such as screws, adhesives, clips, etc., as desired by those skilled in the art. Further, the fixing plate 213 is fixedly coupled to or integrally formed with the first bracket 211.

With reference to fig. 4 to 6, it will be understood by those skilled in the art that, in the assembled state, the heating member 22 is sandwiched by the first bracket 211 and the second bracket 212, and thus the fixed connection of the heating member 22 to the bracket 21 is achieved; the control unit 24 is fixedly connected with the fixing plate 213; the first positioning structure 26 is fixedly connected or integrally made with the first bracket 211, specifically, fixedly connected together through a thread; alternatively, one skilled in the art may fixedly connect or integrate the first positioning structure 26 with the second bracket 212, as desired.

As shown in fig. 5 and 6, the outer edge of the cross section of the first bracket 211 is semicircular, the outer edge of the cross section of the second bracket 212 is semicircular, so that the outer edge of the cross section of the bracket 21 is circular, and a mounting cavity (not labeled) for accommodating the control unit 24 is formed between the first bracket 211 and the second bracket 212. In other words, the bracket 21 is a hollow cylindrical structure, and the inside of the cylindrical structure can accommodate the control unit 24, so as to protect the control unit 24 inside the cylindrical structure and prevent the control unit 24 from being damaged by external force. It will be appreciated by those skilled in the art that the cylindrical configuration of the stent 21 is effective to reduce the radial dimension of the stent 21 while still providing adequate connection to other components.

As shown in fig. 5, the second bracket 212 is further provided with a fixing structure for mounting the key, and a through hole located at the fixing structure. Accordingly, through holes are provided in both the sleeve 25 and the housing 1, so that in the assembled state of the heating non-combustible smoking article, the keys can be inserted into the through holes in the sleeve 25 and the housing 1 and fixedly connected to the second bracket 212, thereby enabling the keys to activate a control switch (not shown) on the control unit 24.

Wherein, the battery 231 is of a cylindrical structure, and the charging terminal 232 is located at a side of the battery 231 away from the bracket 21 and fixedly connected with the sleeve 25, specifically, fixedly connected with the sleeve 25 through the end cap 27. Further, the battery 231 is a lithium polymer battery so that the electric capacity of the battery 231 is changed by changing the axial length of the battery 231 without changing the diameter of the battery 231. Specifically, the diameters of the battery 231 and the charging terminal 232 are smaller than or equal to the diameter of the holder 21, so that the battery 231, the charging terminal 232, and the holder 21 can be smoothly inserted into the through-hole in the housing 1. In order to heat a plurality of (for example, 8, 10, 12, etc.) cigarettes 4 after the battery 231 is fully charged, the capacitance of the battery 231 can be increased or decreased by increasing or decreasing the axial length of the battery 231.

Although not explicitly shown in the drawings, it is apparent from fig. 4 and 5 that the control unit 24 includes a circuit board and a control switch provided on the circuit board. Wherein the circuit board is fixedly mounted to the fixing plate 213 of the bracket 21 and the control switch is aligned with the through hole formed in the second bracket 212. In the present embodiment, the control switch is a push switch, or one skilled in the art may set the control switch to any other feasible switch, such as a touch switch, an infrared sensing switch, etc., as required.

As shown in fig. 4, the sleeve 25, which is an example of a fixing member for fixing the power supply 23 and the bracket 21, has a cylindrical structure in a thin-walled form as a whole, and is further provided with a strip-shaped through hole for allowing the key to pass therethrough. In the case that the power supply 23 and the bracket 21 can be fixed together to prevent the power supply 23 and the bracket 21 from shaking relatively, the skilled person can also set the sleeve 25 as any other fixing member, such as a strip-shaped plate with a C-shaped cross section or a plurality of parallel strip-shaped members, as required.

As shown in fig. 4 and 5, the first locating feature 26 includes a large diameter portion and a small diameter portion with an external thread disposed thereon. Although not shown in the drawings, the first bracket 211 is provided with an internal thread so that the first positioning structure 26 and the first bracket 211 can be threadedly coupled together with the internal thread through the external thread. Further, although not shown in the drawings, a groove is provided as a second positioning structure on the side wall of the housing 1 so that the large diameter portion of the first positioning structure 26 can be fitted into the groove after the core assembly 2 is mounted into the housing 1, thereby fixing the core assembly 2 together in the axial and circumferential directions.

It will be appreciated by those skilled in the art that the first positioning structure 26 may be provided in any feasible configuration, such as a threaded rod of equal diameter, a conical or spherical protrusion formed on the first bracket 211, a groove formed on the first bracket 211, etc., provided that the first positioning structure 26 is matched with the second positioning structure. It will also be appreciated by those skilled in the art that if the first locating feature 26 is a raised feature, then the second locating feature is a recessed feature; if the first locating feature 26 is a recessed feature, then the second locating feature is a raised feature.

As shown in fig. 3 and 4, the cap 27 is fixed to an end of the sleeve 25 away from the heating member 22 by snap-fitting, and the cap 27 is also plugged together with the charging terminal 232 so that the charging terminal 232 is fixed to the sleeve 25 to prevent the charging terminal 232 from shaking when the non-combustible smoking article is heated and charged.

It will be understood by those skilled in the art that the end cap 27 may be omitted as desired by those skilled in the art, provided that the charging terminal 232 can be fixed to the sleeve 25.

Based on the foregoing description, it can be understood by those skilled in the art that, in the first embodiment of the present disclosure, by providing the battery 231 in a cylindrical shape, those skilled in the art can change the capacitance of the battery 231 by changing the length of the battery 231; by providing the battery 231 as a lithium polymer battery, it is convenient for those skilled in the art to change the shape of the battery 231. Further, by disposing the control unit 24 inside the bracket 21, the bracket 21 can effectively protect the control unit 24, and the control unit 24 is prevented from being damaged by external force. Further, by disposing the bracket 21, the power supply 23 and the control unit 24 inside the sleeve 25, not only the power supply 23 and the control unit 24 are effectively protected, but also the respective components of the core assembly 2 are fixed to each other, thereby integrating the entire core assembly 2 into one body, so that the core assembly 2 can be separately produced and assembled. The transportation of the core assembly 2 is facilitated and also a situation in which the core assembly 2 is damaged during the installation into the sleeve 2 is avoided due to the presence of the sleeve 25.
