[0038] Please refer to Figures 1 to 6, this application provides a heat-not-burn device 100. The heat-not-burn device 100 is used to heat an aerosol-forming substrate 200. In this embodiment, the heat-not-burn device 100 includes a housing 110, a mounting seat 120, and a heating element 130. The aerosol-forming substrate 200 includes a filter element 210, a cooling section 220, and an opening section 230. During use, the opening section 230 extends into the mounting seat 120. The heating element 130 heats the opening section 230 to generate an aerosol for suction. The filter element 210 is exposed outside the heat-not-burn device 100 for the user to suction the generated aerosol.

[0039] The mounting seat 120 is disposed within the housing 110. The mounting seat 120 is used for mounting the aerosol-forming substrate 200.

[0040] The heating element 130 is used to heat the aerosol-forming substrate 200. In this embodiment, the heating element 130 extends into the mounting seat 120 to heat the aerosol-forming substrate 200.

[0041] The mounting seat 120 includes a first accommodating section 121 and a second accommodating section 122. The first accommodating section 121 is disposed near the opening of the mounting seat 120. The second accommodating section 122 is disposed near the bottom of the mounting seat 120. The inner diameter of the first accommodating section 121 is larger than the inner diameter of the second accommodating section 122, so that the portion of the aerosol-forming substrate 200 located in the second accommodating section 122 is squeezed and contracted.

[0042] In the above heat-not-burn device 100, by dividing the mounting seat 120 into a first accommodating section 121 and a second accommodating section 122, and making the inner diameter of the first accommodating section 121 larger than the inner diameter of the second accommodating section 122, when the aerosol-forming substrate 200 is inserted into the mounting seat 120, its end will be squeezed and contracted by the second accommodating section 122, so that the residual slag in the aerosol-forming substrate 200 is not easily scattered. The above setting method enables the user not to frequently clean the residual slag in the heat-not-burn device, improving the user experience.

[0043] In this embodiment, the heating element 130 generates heat after being powered on, thereby baking and heating the aerosol-forming substrate 200. During actual use, the heating element 130 is inserted into the interior of the aerosol-forming substrate 200. The heat generated by the heating element 130 after being powered on is transferred to the aerosol-forming substrate 200 and heats the aerosol-forming substrate 200. In this embodiment, the heating element 130 is made of metal or ceramic. In another embodiment, the heating element 130 can also be heated by electromagnetic induction. At this time, the heating element 130 is made of soft magnetic material.

[0044] In one embodiment, the mounting base 120 further includes a bottom support 123. The bottom support 123 is disposed at the bottom of the mounting base 120. The bottom support 123 extends inward from the bottom of the second accommodation section 122 to support the open end face of the aerosol-forming substrate 200. A through hole 1231 is provided at the center of the bottom support 123. The heating element 130 passes through the through hole 1231 and extends into the interior of the mounting base 120.

[0045] By providing the bottom support 123 at the bottom of the mounting base 120 and making the bottom support 123 extend inward from the bottom of the second accommodation section 122, when the aerosol-forming substrate is inserted into the mounting base 120, the bottom support 123 can effectively support the bottom of the aerosol-forming substrate 200. On the one hand, the provision of the bottom support 123 allows the user to feel that the aerosol-forming substrate 200 has been installed in place. On the other hand, the provision of the bottom support 123 also makes it difficult for the residual slag in the aerosol-forming substrate 200 to fall downward, avoiding the problem of frequently cleaning the heat-not-burn device 100. In fact, during the installation of the aerosol-forming substrate 200, the aerosol-forming substrate 200 first passes through the first accommodation section 121 of the mounting base 120. The inner diameter of the first accommodation section 121 is set to be substantially the same as the diameter of the aerosol-forming substrate 200. At this time, the aerosol-forming substrate 200 can be easily inserted into the first accommodation section 121 of the mounting base 120. Then, after passing through the first accommodation section 121, the aerosol-forming substrate 200 reaches the second accommodation section 122. Since the inner diameter of the second accommodation section 122 is smaller than the inner diameter of the first accommodation section 121, the second accommodation section 122 squeezes and contracts the aerosol-forming substrate 200, so that the end of the aerosol-forming substrate 200 forms a closed shape. When the aerosol-forming substrate 200 moves to the position of the bottom support 123, it proves that the aerosol-forming substrate 200 has been installed in place. At this time, the inward extension design of the bottom support 123 can further support the open end face of the aerosol-forming substrate 200, so that the residual slag in the aerosol-forming substrate 200 after use is not easily scattered into the heat-not-burn device 100 again.

[0046] In this embodiment, the diameter of the through hole 1231 at the center of the base 123 is larger than the diameter of the heating element 130, so that during use by the user, air can flow through the through hole 1231 at the center of the base 123 and then pass through the aerosol-forming matrix 200. In fact, the diameter of the through hole 1231 at the center of the base 123 may also be the same as the diameter of the heating element 130. At this time, a plurality of ventilation holes may be provided around the through hole 1231 of the base 123. The diameter of the ventilation holes may be set relatively small, so that the residual slag of the aerosol-forming matrix 200 is not easily scattered from the ventilation holes.

[0047] As required, a first transition section 124 is formed between the first accommodating section 121 and the second accommodating section 122. The inner diameter of the first transition section 124 gradually decreases from top to bottom. That is, by setting the inner diameter of the first transition section 124 to gradually decrease from top to bottom, when the aerosol-forming matrix 200 moves from the first accommodating section 121 to the second accommodating section 122, the setting of the converging shape of the first transition section 124 can make the movement of the aerosol-forming matrix 200 smoother.

[0048] As required, a second transition section 125 is formed between the second accommodating section 122 and the base 123. The inner diameter of the second transition section 125 gradually decreases from top to bottom. Similarly, by setting the inner diameter of the second transition section 125 to gradually decrease from top to bottom, when the aerosol-forming matrix 200 moves from the second accommodating section 122 to the base 123, the setting of the converging shape of the second transition section 125 can make the movement of the aerosol-forming matrix 200 smoother and make the opening of the aerosol-forming matrix 200 tighter.

[0049] Please refer to Figures 7 to 9, in this embodiment, a first air flow channel 126 is provided on the outer wall surface of the mounting base 120. The first air flow channel 126 is recessed in the outer wall surface of the mounting base 120. The first air flow channel 126 includes a first connecting section 1261 and a first expansion section 1262. The first connecting section 1261 extends from top to bottom. The first expansion section 1262 is provided at the bottom of the first connecting section 1261 and has a flared opening shape. By providing the first air flow channel 126, outside air can flow through the first air flow channel 126 into the interior of the heat-not-burn device 100, then pass through the through hole 1231 in the center of the base 123, and reach the aerosol-forming substrate 200. In fact, in order to make the air flow entering the aerosol-forming substrate 200 more uniform, a first expansion section 1262 is provided at the bottom position of the first air flow channel 126. The first expansion section 1262 is provided with a flared opening, which can enable the air to fully diffuse when flowing from the first connecting section 1261 to the first expansion section 1262, so as to uniformly flow into the interior of the mounting base 120 from the through hole 1231 in the center of the base 123.

[0050] Similarly, a second air flow channel 127 is provided on the outer wall surface of the mounting base 120. The second air flow channel 127 is recessed in the outer wall surface of the mounting base 120. The second air flow channel 127 includes a second connecting section 1271 and a second expansion section 1272. The second connecting section 1271 extends from top to bottom. The second expansion section 1272 is provided at the bottom of the second connecting section 1271 and has a flared opening shape. Similarly, by providing the second air flow channel 127, outside air can flow through the second air flow channel 127 into the interior of the heat-not-burn device 100, then pass through the through hole 1231 in the center of the base 123, and reach the aerosol-forming substrate 200. In this embodiment, the first air flow channel 126 and the second air flow channel 127 are uniformly arranged along the circumferential direction of the outer wall surface of the mounting base 120, so as to make the air flow move more uniformly.

[0051] As needed, the flared openings of the first expansion section 1271 and the second expansion section 1272 are communicated, so that the air flows in the first air flow channel 126 and the second air flow channel 127 converge at the junction of the first expansion section 1262 and the second expansion section 1272.

[0052] It can be understood that the setting of the air flow channels is not limited to two, and it can also be three or more. In this embodiment, a plurality of air intake holes 111 are provided at the top of the housing 110. Outside air enters the first air flow channel 126 or the second air flow channel 127 through the air intake holes 111.

[0053] In this embodiment, the heat-not-burn device 100 further includes a base 140.

[0054] The base 140 includes a base body 141 and a connecting portion 142 extending upward from the base body 141. The heating element 130 is disposed on the base body 141. The connecting portion 142 is disposed in the gap between the housing 110 and the mounting base 120. In this embodiment, by dividing the base 140 into the base body 141 and the connecting portion 142 and disposing the connecting portion 142 in the gap between the housing 110 and the mounting base 120, this mounting method can make the assembly between the base 140 and the outer shell 110 and the mounting base 120 tighter.

[0055] In this embodiment, the connecting portion 142 is cylindrical. The inner wall surface of the connecting portion 142 is provided with a first positioning member 1421 and a second positioning member 1422. The first positioning member 1421 and the second positioning member 1422 protrude from the inner wall surface of the connecting portion 142. The first positioning member 1421 is engaged in the first air flow channel 126 on the outer wall surface of the mounting base 120. The second positioning member 1422 is engaged in the second air flow channel 127 on the outer wall surface of the mounting base 120. By providing the first positioning member 1421 and the second positioning member 1422 on the inner wall surface of the connecting portion 142 and engaging the first positioning member 1421 and the second positioning member 1422 in the first air flow channel 126 and the second air flow channel 127 respectively, the above setting method can make the installation process of the connecting portion 142 and the mounting base 120 achieve precise positioning. In fact, the first positioning member 1421 and the second positioning member 1422 are ribs protruding from the inner wall surface of the connecting portion 142. The ribs extend from bottom to top. During the installation process of the base 140 and the mounting base 120, as long as the positions of the first positioning member 1421 and the second positioning member 1422 are aligned with the positions of the first air flow channel 126 and the second air flow channel 127, the base 140 and the mounting base 120 can be conveniently assembled. According to needs, the widths of the first positioning member 1421 and the second positioning member 1422 can be set to gradually extend from top to bottom. At this time, in the first air flow channel 126 and the second air flow channel 127, the widths of the first communication section 1261 and the second communication section 1271 can also be set to gradually extend from top to bottom, so that the cooperation between the first positioning member 1421 and the first air flow channel 126, and the second positioning member 1422 and the second air flow channel 127 is more precise.

[0056] The present application also provides a mounting base 120, which is disposed in the heat-not-burn device 100 and is used for mounting the aerosol-forming substrate 200.

[0057] The mounting base 120 includes a first accommodating section 121 and a second accommodating section 122. The first accommodating section 121 is disposed near the opening of the mounting base 120. The second accommodating section 122 is disposed near the bottom of the mounting base 120. The inner diameter of the first accommodating section 121 is larger than that of the second accommodating section 122, so that the portion of the aerosol-forming substrate 200 located in the second accommodating section 122 is squeezed and contracted.

[0058] In the mounting base 120 provided in the above embodiment, by dividing the mounting base 120 into a first accommodating section 121 and a second accommodating section 122, and making the inner diameter of the first accommodating section 121 larger than that of the second accommodating section 122, when the aerosol-forming substrate 200 is inserted into the mounting base 120, its end portion will be squeezed and contracted by the second accommodating section 122, so that the residual slag in the aerosol-forming substrate 200 is not easily scattered. The above setting method enables users not to frequently clean the residual slag in the heat-not-burn device 100, improving the user experience.

[0059] For the sake of description, spatial relative terms, such as "above", "on top of", "on the upper surface", "over", etc., may be used here to describe the spatial position relationship between one device or feature and other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, the device described as "above" or "on top of" other devices or structures will then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be oriented in other different ways (rotated 90 degrees or at other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.

[0060] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without further statement, the above words have no special meaning, so they cannot be construed as limiting the protection scope of the present application.

[0061] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
