In an embodiment, the protrusion 123 includes a plurality of protruding points 124 and/or a plurality of protruding strips 125 arranged at intervals. The outer side wall of the hollow cylindrical body of the heating element 121 is recessed into the receiving cavity 122 to form a protruding point 124 and/or a protruding strip 125. In this way, the protrusions 124 and/or the ribs 125 are formed by punching from the outer sidewall of the hollow cylindrical body to the inside of the receiving cavity 122 through a die.

In order to more uniformly transmit the heat generated by the heat generating member 121 to the aerosol generating assembly 2, the plurality of protrusions 124 or the plurality of ribs 125 are disposed at equal intervals along the circumference of the hollow cylindrical body.
In an embodiment, referring to fig. 6, the protrusion 123 only includes a plurality of bumps 124. The protrusion 123 may include only one bump 124, and the number of bumps 124 may be set according to actual conditions. In order to reduce the resistance of the aerosol generating assembly 2 during insertion into or withdrawal from the receiving cavity 122, the surface of the protrusions 124 remote from the inner sidewall of the receiving cavity 122 is provided as a spherical surface. In other embodiments, the surface of the protruding point 124 away from the inner sidewall of the receiving cavity 122 may have other shapes as long as it can closely contact with the aerosol generating assembly 2 to transfer heat. In this embodiment, twenty-four bumps 124 are uniformly distributed on the inner sidewall of the accommodating cavity 122 in an array, the plurality of bumps 124 may be distributed in a plurality of rows, each row of bumps 124 is arranged along the axial direction of the heat generating member 121, and the plurality of rows of bumps 124 are arranged at intervals in the circumferential direction of the heat generating member 121.

The protrusion 123 may include only one protrusion 125, and the number of the protrusions 125 may be set according to actual circumstances. The plurality of ribs 125 extend in a direction from the air outlet 129 toward the bottom of the receiving chamber 122. In order to reduce the resistance of the aerosol-generating assembly 2 during insertion into or withdrawal from the receiving cavity 122, the end surfaces of the protruding strips 125 close to the air outlet 129 and the end surfaces far away from the air outlet 129 are of a slope structure. Specifically, one side of the end surface of the protruding strip 125 close to the air outlet 129, which is close to the inner side wall of the accommodating cavity 122, is higher than one side of the end surface of the protruding strip 125 close to the air outlet 129, which is far away from the inner side wall of the accommodating cavity 122; one side of the end surface of the protruding strip 125 far away from the air outlet 129, which is close to the inner side wall of the accommodating cavity 122, is lower than one side of the end surface of the protruding strip 125 far away from the air outlet 129, which is far away from the inner side wall of the accommodating cavity 122. In the present embodiment, four protruding strips 125 are uniformly circumferentially distributed on the inner sidewall of the accommodating cavity 122, and the extending direction of the protruding strips 125 is parallel to the central axis direction of the heating element 121.
In another embodiment, referring to fig. 8, the protrusion 123 includes a plurality of bumps 124 and a plurality of ribs 125. The bumps 124 and the ribs 125 may be alternately arranged at equal intervals. The distribution length of the protruding points 124 extending from the air outlets 129 to the bottom of the accommodating cavity 122 may be the same as the length of the protruding strips 125.
In order to enable the protrusion 123 to be in contact with the aerosol generating assembly 2 more sufficiently, more heat generated by the heat generating member 121 can be transferred to the aerosol generating assembly 2 through the protrusion 123, and the speed of generating aerosol by heating the aerosol generating substrate 21 by the heat generating member 121 is increased. The protrusion 123 includes a closed ring-shaped body or an unclosed arc-shaped rib extending along the circumferential direction of the hollow cylindrical body.
In an embodiment, referring to fig. 9, a portion of the sidewall of the heat generating element 121 close to the air outlet 129 is recessed to form an annular throat 127, the annular throat 127 serves as the protrusion 123, and the annular throat 127 is a closed ring. Wherein, the inner diameter of the annular necking part 127 is smaller than the inner diameter of the other part of the hollow cylindrical body, and the outer diameter of the annular necking part 127 is smaller than the outer diameter of the other part of the hollow cylindrical body. Wherein, the connection part of the annular necking part 127 and the other parts of the hollow cylindrical body is in an arc surface structure.
In another embodiment, referring to fig. 10, a portion of the inner sidewall of the accommodating cavity 122 near the air outlet 129 is provided with a protruding ring 126, the protruding ring 126 serves as the protrusion 123, and the protruding ring 126 is a closed ring. Specifically, the outer sidewall of the hollow cylindrical body of the heat generating member 121 is recessed into the receiving cavity 122 to form a convex ring 126. In this manner, the raised ring 126 is stamped from the outer surface of the hollow cylinder into the interior of the receiving cavity 122 by a die. The boss 123 is simple in processing technology and low in cost. In one embodiment, the protruding ring 126 on the inner sidewall of the receiving cavity 122 may also be a protrusion disposed on the inner sidewall of the receiving cavity 122. The connection part of the convex ring 126 and the inner side wall of the accommodating cavity 122 is an arc surface structure.
In order to enable the aerosol generating assembly 2 to be aligned and more conveniently inserted into the accommodating cavity 122, the protrusion 123 and the air outlet 129 are spaced, so that the inner diameter of the accommodating cavity 122 close to the end of the air outlet 129 is larger than the diameter of the aerosol generating assembly 2, the aerosol generating assembly 2 is conveniently aligned and inserted into the air outlet 129 of the accommodating cavity 122, and after the aerosol generating assembly 2 enters the air outlet 129, the aerosol generating assembly 2 passes through the part of the accommodating cavity 122 where the protrusion 123 is arranged, so that the aerosol generating assembly 2 is tightly attached to the protrusion 123.
In order to reduce the resistance of the aerosol generating assembly 2 during insertion or withdrawal from the receiving chamber 122, the receiving chamber 122 has a raised portion 123 only on a portion of the inner sidewall thereof adjacent to the air outlet 129. Further, in order to ensure that the heating element 121 can be in full contact with the aerosol generating assembly 2 and transfer more heat to the aerosol generating assembly 2, and also in order to facilitate the insertion or withdrawal of the aerosol generating assembly 2 into or out of the accommodating cavity 122, the ratio of the length of the protruding portion 123 in the direction parallel to the central axis of the hollow cylindrical body to the length of the hollow cylindrical body is 1:10-1: 2. In one embodiment, the ratio of the length of the protrusion 123 in a direction parallel to the axis in the hollow cylindrical body to the length of the hollow cylindrical body is 1: 7. In one embodiment, the ratio of the length of the protrusion 123 in the direction parallel to the central axis of the hollow cylindrical body to the length of the hollow cylindrical body is 1: 5. In a preferred embodiment, the ratio of the length of the protrusion 123 in a direction parallel to the central axis of the hollow cylindrical body to the length of the hollow cylindrical body is 1: 3.
In an embodiment, in order to further reduce the resistance, the insertion or withdrawal of the aerosol generating assembly 2 into or out of the accommodating cavity 122 is more convenient, the inner wall surfaces of the accommodating cavity 122 are smooth wall surfaces, and the surface of the protrusion 123 contacting with the aerosol generating assembly 2 is also a smooth surface.
In one embodiment, the maximum height of the projections 123 is 1mm to 4 mm. The maximum height of the protrusion 123 refers to the maximum height of the protrusion 123 protruding from the inner sidewall of the accommodating cavity 122. The maximum height of the protrusion 123 can be adjusted to adjust the width of the gap between the inner side wall of the accommodating cavity 122 and the aerosol generating assembly 2, so that the heat generated by the heat generating member 121 is controlled to be transferred to the aerosol generating assembly 2 through the air between the inner side wall of the accommodating cavity 122 and the aerosol generating assembly 2. If the maximum height of the protrusion 123 is too high, the gap between the inner sidewall of the accommodating cavity 122 and the aerosol generating assembly 2 is too wide, which is not favorable for the aerosol generating assembly 2 to receive the heat transferred by the heat generating member 121, and more heat loss is easily caused.
