In the design of the existing aerosol generating device for stably clamping the aerosol matrix, a latex lining is generally used to clamp and fix the aerosol matrix.

[0003] The existing method of using a latex lining to clamp aerosol matrices of different diameters can stably fix a part of the aerosol matrix. However, due to the design of the raised latex lining filled with latex in the clamping part, the material consumption is large and the cost is high. Moreover, during the insertion and extraction of the aerosol matrix, the raised latex lining is driven by the aerosol matrix and undergoes longitudinal displacement deformation, resulting in unsmooth insertion and extraction of the aerosol matrix. Summary of the Utility Model

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof is not required in subsequent drawings.

[0037] See Figures 1 to 7 As shown, the present application provides an aerosol generating device 100 that can stably hold an aerosol substrate. The aerosol generating device 100 includes a housing 10 having a receiving cavity inside for receiving the insertion of the aerosol substrate 30. The aerosol generating device 100 further includes a clamping mechanism 20. The clamping mechanism 20 includes a cantilever 22 extending into the receiving cavity. When the aerosol substrate 30 is inserted into the receiving cavity, the aerosol substrate 30 presses against the cantilever 22, causing the cantilever 22 to open radially away from the central axis of the receiving cavity to allow the aerosol substrate 30 to be inserted into the receiving cavity. The cantilever 22 generates a radial force on the aerosol substrate 30, thereby clamping and fixing the aerosol substrate 30 by the cantilever 22. When the aerosol substrate 30 is withdrawn from the receiving cavity, the cantilever 22 radially resets towards the central axis of the receiving cavity.

[0038] The cantilever 22 can be a pair of cantilevers 22 symmetrically arranged on both sides of the receiving cavity, or can be multiple cantilevers 22. Preferably, the cantilever 22 is arranged around the inner wall of the receiving cavity for one week.

[0039] The cantilever 22 extending into the interior of the receiving cavity through the clamping mechanism 20, while achieving stable clamping of the aerosol matrix 30, reduces the longitudinal displacement deformation of the clamping mechanism 20 during the insertion and extraction of the aerosol matrix 30, improving the smoothness of the insertion and extraction actions of the aerosol matrix 30. In this embodiment, the cantilever 22 of the clamping mechanism 20 extending into the receiving cavity plays a certain positioning and guiding role in the action of inserting the aerosol matrix 30 into the receiving cavity, making it easier for the aerosol matrix 30 to align with the receiving cavity when inserted.

[0040] In some embodiments, compared with the existing design of the clamping part using a raised latex lining filled with latex, by adopting the design of a pair of symmetrically arranged cantilevers 22, the use of elastic materials is reduced, and the production cost is reduced.

[0041] See Figures 1 to 5 As shown, the position of the cantilever 22 for clamping the aerosol matrix 30 is provided with a rounded corner, which can reduce the contact area between the cantilever 22 and the aerosol matrix 30, thereby reducing the friction between the cantilever 22 and the aerosol matrix 30, and improving the smoothness of the insertion and extraction process of the aerosol matrix 30. Since the aerosol matrix 30 is a non-rigid cylinder, by providing a rounded corner at the position of clamping the aerosol matrix 30, it plays a guiding role when the aerosol matrix 30 is pulled out of the receiving cavity, thereby improving the smoothness of the aerosol matrix 30 being pulled out of the receiving cavity.

[0042] See Figures 1 to 8 As shown, the clamping mechanism 20 surrounds the inner wall of the receiving cavity, making the clamping force received by the aerosol matrix 30 more uniform, and at the same time improving the stability of clamping the aerosol matrix 30. Compared with the existing multi-point clamping scheme for the aerosol matrix 30, in this embodiment, the aerosol matrix 30 is uniformly stressed, ensuring the integrity of the appearance of the aerosol matrix 30.

[0043] See Figure 1 、 Figures 4 to 5 and Figures 7 to 11 As shown, the clamping mechanism 20 further includes a fixing part 21, the cantilever 22 is connected to the fixing part 21, and the fixing part 21 is connected to the housing 10. The housing 10 includes a first axial limiting part 1111, a second axial limiting part 1211 and a radial limiting part 1121. The first axial limiting part 1111 and the second axial limiting part 1211 are connected by the radial limiting part 1121. The clamping mechanism 20 is axially clamped between the first axial limiting part 1111 and the second axial limiting part 1211, and the radial limiting part 1121 surrounds the clamping mechanism 20 to limit the radial position of the clamping mechanism 20.

[0044] Specifically, during the process of inserting or removing the aerosol substrate 30 into or from the receiving cavity, the friction between the clamping mechanism 20 and the aerosol substrate 30 drives the clamping mechanism 20 to have a tendency to move downward or upward. By axially clamping the clamping mechanism 20 between the first axial limiting portion 1111 and the second axial limiting portion 1211, the axial position of the clamping mechanism 20 is restricted, thereby restricting the downward or upward movement of the clamping mechanism 20 driven by the aerosol substrate 30, so that the aerosol substrate 30 can be smoothly inserted or removed.

[0045] In addition, when the aerosol substrate 30 is inserted into the receiving cavity, the clamping mechanism 20 deforms outward relative to the receiving cavity. The radial limiting portion 1121 restricts the outward deformation of the clamping mechanism 20 and at the same time provides a radial force towards the receiving cavity for the clamping mechanism 20, which can improve the stability of the clamping mechanism when clamping the aerosol substrate 30.

[0046] Through the settings of the first axial limiting portion 1111 / the second axial limiting portion 1211 / the radial limiting portion 1121, the clamping mechanism 20 is fixedly limited, so that the aerosol substrate 30 can be smoothly inserted or removed.

[0047] More specifically, the clamping mechanism 20 is connected to the first axial limiting portion 1111 / the second axial limiting portion 1211 / the radial limiting portion 1121 of the housing 10 through the fixing portion 21, thereby fixing the clamping mechanism 20.

[0048] See Figures 1 to 7 As shown, the housing 10 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are snap-connected to form an installation space for installing and fixing the clamping mechanism 20. The first housing 11 is provided with a first axial limiting portion 1111 and a radial limiting portion 1121 that are connected to each other. The second housing 12 is provided with a second axial limiting portion 1211. The radial limiting portion 1121 is snap-connected to the second axial limiting portion 1211. The clamping mechanism 20 is axially clamped between the first axial limiting portion 1111 and the second axial limiting portion 1211, and the radial limiting portion 1121 surrounds the clamping mechanism 20 to define the radial position of the clamping mechanism 20. By splitting the housing 10 into the first housing 11 and the second housing 12, and installing the clamping mechanism 20 in the installation space between the first housing 11 and the second housing 12, the installation of the clamping mechanism 20 is made more convenient.

[0049] See Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 12As shown, the first housing 11 includes a first cover 111 and a first peripheral wall 112. A first axial limiting portion 1111 is provided on the first cover 111. The first peripheral wall 112 extends downward along the outer edge of the first cover 111. A radial limiting portion 1121 is provided on the first peripheral wall 112. The first cover 111 is provided with a first through hole 114 for the aerosol matrix 30 to pass through.

[0050] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figures 7 to 11 As shown, the clamping mechanism 20 includes a second cover 211 and a second peripheral wall 212. The second peripheral wall 212 extends downward along the outer edge of the second cover 211. The second cover 211 is provided with a second through hole 23 for the aerosol matrix 30 to pass through. A cantilever 22 extends downward along the edge of the second through hole 23. The second cover 211 and the second peripheral wall 212 are a fixing portion 21.

[0051] See Figure 1 , Figure 5 , Figure 4 , Figure 5 , Figure 7 , Figure 13 As shown, the second housing 12 includes a third cover 121 and a third peripheral wall 123. The third peripheral wall 123 extends axially along the outer edge of the third cover 121. The third cover 121 is provided with a third through hole for the aerosol matrix 30 to pass through. The third cover 121 is provided with a positioning portion 125 between the third peripheral wall 123 and the central axis of the second housing 12. The positioning portion 125, the third cover 121 and the third peripheral wall 123 form a limiting groove 126. The second peripheral wall 212 is embedded in the limiting groove 126, so as to fix the radial position of the second peripheral wall 212, and further fix the radial position of the clamping mechanism 20, improving the accuracy when the aerosol matrix 30 is inserted into the receiving cavity. When the aerosol matrix 30 is inserted into or pulled out of the receiving cavity, the second peripheral wall 212 is prone to deformation. In this embodiment, the positioning portion 125 can limit the deformation of the bottom end of the second peripheral wall 212 towards the receiving cavity, preventing the second peripheral wall 212 from being deformed excessively, resulting in the smooth insertion or extraction of the aerosol matrix 30 into or out of the receiving cavity. At the same time, the positioning portion 125 can limit the excessive outward deformation of the cantilever 22. A second axial limiting portion 1211 is provided on the third cover 121.

[0052] Preferably, as Figure 4 , Figure 5 , Figure 7 , Figure 12As shown, the first peripheral wall 112 surrounds and forms a stepped first receiving hole 115 and a second receiving hole 116. The first receiving hole 115 is smaller than the second receiving hole 116. The first receiving hole 115 is close to the first through hole 114. A positioning step 117 is formed at the connection of the first receiving hole 115 and the second receiving hole 116. The clamping mechanism 20 is embedded in the first receiving hole 115, and the second cover body 211 of the clamping mechanism 20 abuts against the first cover body 111. The second housing 12 is embedded in the second receiving hole 116, and the third peripheral wall 123 of the second housing 12 abuts against the positioning step 117. By nesting the clamping mechanism 20 in the first receiving hole 115 and embedding the second housing 12 in the second receiving hole 116, the gap between the first housing 11 and the second housing 12 is sealed by the clamping mechanism 20, improving the airtightness of the receiving cavity, preventing the aerosol from overflowing through the gap between the first housing 11 and the second housing 12, and further preventing the aerosol from leaking to the control module, affecting the normal operation of the control module or the power module, or even causing the function to fail and the aerosol generating device 100 to be unable to work, thus improving the service life of the aerosol generating device 100.

[0053] In some embodiments, as Figure 2 shown, the fixing part 21 of the clamping mechanism 20 is the second cover body 211 and the second peripheral wall 212. The first axial limiting part 1111 is arranged on the first cover body 111, the radial limiting part 1121 is arranged on the first peripheral wall 112, and the second axial limiting part 1211 is arranged on the third cover body 121. The first axial limiting part 1111, the radial limiting part 1121, and the second axial limiting part 1211 fix and limit the fixing part 21, that is, the first cover body 111, the first peripheral wall 112, and the second axial limiting part 1211 fix and limit the second cover body 211 and the second peripheral wall 212.

[0054] See Figures 1 to 7 and Figure 12 and Figure 13 shown, a pair of buckles 113 are symmetrically arranged at the bottom end of the first peripheral wall 112.

[0055] The third peripheral wall 123 is provided with a slot 122 corresponding to the buckle 113, and the buckle 113 is embedded in the slot 122 to snap-connect the first housing 11 and the second housing 12.

[0056] See Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 shown, the aerosol generating device 100 further includes a heating module 40 arranged in the housing 10. The heating module 40 is used to heat the aerosol substrate 30 inserted into the receiving cavity. Among them, the heating module is a conventional technology in the art, so the specific working principle thereof will not be described in detail here.

[0057] SeeFigure 1 , Figure 2 , Figure 4 , Figure 5 As shown in Figure 5 , the aerosol generating device 100 further includes a heating module 40 disposed in the housing 10. The heating module 40 is cylindrical, and a space is formed inside the heating module 40 for the aerosol substrate 30 to pass through to heat the outside of the aerosol substrate 30.

[0058] The aerosol generating device 100 further includes a receiving seat 50 disposed at the bottom of the receiving cavity. The outer wall of the receiving seat 50 is embedded in the second housing 12. A stepped blind hole 51 is formed on one side of the receiving seat 50 facing the first housing 11. The opening end of the blind hole 51 faces the first housing 11. A plurality of air flow channels communicating with the receiving cavity are formed at the bottom of the blind hole 51. A second step 52 is formed on the inner wall of the blind hole 51. The blind hole 51 is used to receive the bottom of the aerosol substrate 30; the air flow channels are specifically connected to the air duct and then communicate with the outside. So that the aerosol generated when the heating module 40 in the receiving cavity heats the aerosol substrate can be connected to the outside air.

[0059] A positioning wall 127 is formed on the outer edge of the third through hole 124 of the second housing 12 and extends towards the receiving seat 50. A first step 128 is provided on the side of the positioning wall 127 facing the receiving seat. The heating module 40 is clamped between the first step 128 and the second step 52 to fix the position of the heating module 40.

[0060] The control module, the power module, and the air duct are all conventional technologies in the art, so the layout and connection thereof will not be described in detail here.

[0061] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "above" etc. may be used herein to describe the spatial position relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations will be made to the spatial relative descriptions used herein.

[0062] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of differentiating the corresponding components. Without further statement, the above terms have no special meaning, and thus should not be construed as limiting the protection scope of the present application.
