In order to prevent the atomizing matrix from falling out of the plug-in cavity, a fastening structure is provided at the insertion port of the plug-in cavity, and the fastening structure can fix the atomizing matrix inserted into the plug-in cavity. In the related art, some fastening structures use positioning protrusions, and the positioning protrusions protrude from the side wall of the plug-in cavity. When the atomizing matrix is ​​inserted, it can form an interference fit with the outer peripheral surface of the atomizing matrix, thereby fixing the atomizing matrix.

[0004] However, the positioning protrusion will increase the difficulty of molding the corresponding structure, and it is not easy to measure whether the size of the positioning protrusion is qualified, which is not conducive to product quality control and thus increases the difficulty of manufacturing.

[0040] In an embodiment of the utility model, the atomizing matrix fixing part 300 of the atomizing device is provided with a throat 311 with a flat wall surface, and an interference fit with the atomizing matrix 400 is achieved by relying on the non-circular shape formed by the difference in aperture size of the throat 311 in different directions. Compared with providing protrusions on the inner wall of the plug-in channel 310, there is no need to form each protrusion separately, and the structure is simple and easy to manufacture.

[0041] Embodiment of the atomizing device in the utility model:

[0042] Please refer to Figures 1 to 3 In one embodiment, the atomization device includes a device housing 100 , an atomization core assembly 200 , and an atomization substrate fixing member 300 .

[0043] The shape of the device housing 100 is not limited. The device housing 100 is provided with a substrate insertion port 120. The substrate insertion port 120 may be a through hole provided on the device housing 100, and a rod-shaped atomizing substrate 400 may be inserted therein. Components corresponding to the substrate insertion port 120 are provided in the device housing 100. These components may include an atomizing core assembly 200. The atomizing core assembly 200 is provided in the device housing 100. The atomizing core assembly 200 is provided with an atomizing cavity. The atomizing substrate 400 inserted from the substrate insertion port 120 can enter the atomizing cavity. The atomizing core assembly 200 can generate heat to heat the atomizing substrate 400, thereby generating an aerosol.

[0044] In a specific embodiment, please refer to Figure 3 and Figure 4The device housing 100 includes a top cover portion 110, which can be detachably fixed to the main body of the device housing 100, arranged corresponding to the atomizer core assembly 200, and is convenient for assembling the atomizer core assembly 200. The top cover portion 110 is fixed to the main body in any manner, such as snap-on fixing, threaded fastener fixing, interference fit, etc. The matrix insertion port 120 is provided on the top cover portion 110, and can allow the inserted atomizer matrix 400 to enter the atomizer core assembly 200.

[0045] The atomizer core assembly 200 may include an outer cylinder 210, an inner cylinder 220 and a core base 230. The outer cylinder 210 can be fixed on a corresponding support structure in the device housing 100. The inner cylinder 220 is coaxially fixed in the outer cylinder 210. The core base 230 is embedded in the bottom of the outer cylinder 210. The inner cylinder 220 can rely on the connection seat at the top of the outer cylinder 210 and the core base 230 to achieve radial positioning and axial positioning. The inner cylinder 220 can be inserted into the rod-shaped atomizer matrix 400, and the core base 230 can form an axial positioning for the rod-shaped atomizer matrix 400. In addition, an air intake channel can be provided on the core base 230. When the user inhales, the air intake channel can allow external air to enter and generate airflow to discharge aerosol.

[0046] The structural form and specific structure of the atomizer core assembly 200 may adopt various existing structures in the relevant technology, and may have no direct connection with the core content to be protected by this application, and will not be introduced in detail in this application.

[0047] The diameter of the matrix insertion port 120 and the diameter of the inner cylinder 220 are often larger than the diameter of the atomizing matrix 400. After the rod-shaped atomizing matrix 400 is inserted into the atomizing device, in order to avoid easy escaping from the atomizing device, the atomizing device also includes an atomizing matrix fixing part 300. The atomizing matrix fixing part 300 is arranged at the entrance of the matrix insertion port 120. The top surface of the atomizing matrix fixing part 300 can be flush with the edge of the entrance end of the matrix insertion port 120, or it can have a certain indentation relative to the edge of the entrance end of the matrix insertion port 120, that is, it is lower than the edge of the entrance end of the matrix insertion port 120.

[0048] In one embodiment, the atomizing substrate fixing member 300 is annular and is disposed between the atomizing core assembly 200 and the device housing 100 along the axial direction of the substrate insertion port 120. Figure 4It can be understood that a positioning groove 111 can be provided on the device housing 100, and the positioning groove 111 can be embedded in the atomizing matrix fixing member 300 to position the atomizing matrix fixing member 300. The atomizing matrix fixing member 300 can be made of elastic material, such as silicone, so that a sealed connection can be formed with the device housing 100 and the atomizing core assembly 200 to avoid air leakage. Of course, in some other embodiments, the atomizing matrix fixing member 300 can also be positioned in other ways, such as being positioned on the atomizing core assembly 200.

[0049] The atomizing substrate fixing part 300 includes a fixing part body, on which a plug-in channel 310 for inserting a rod-shaped atomizing substrate 400 is provided, and the plug-in channel 310 has a throat 311, and the throat 311 is used to be interference-fitted with the outer peripheral surface of the atomizing substrate 400 inserted into the plug-in channel 310, so as to fix the atomizing substrate 400. The inner wall surfaces on each side of the throat 311 are flat wall surfaces, and the flat wall surface is that no protrusions are provided on the wall surface. In each direction perpendicular to the axial direction of the plug-in channel 310, the aperture size of the throat 311 in at least one direction is smaller than the aperture size in at least one other direction.

[0050] The throat 311 has different aperture sizes in different directions, forming a non-circular shape. For the atomizing matrix 400 whose outer peripheral surface is a cylindrical surface, an interference fit can be formed with the atomizing matrix 400 by relying on the portion with a smaller aperture size. Compared with setting a protrusion on the inner wall of the plug-in channel 310, the utility model has a simple structure, is easy to form and perform dimensional inspection after forming, and ensures product quality.

[0051] In a specific embodiment, please refer to Figure 5 , Figure 6 , the opening formed by the throat 311 is in the shape of an oblong, the inner wall surface of the throat 311 is composed of a plane 312 and a curved surface 313, the plane 312 and the curved surface 313 are smoothly connected and arranged around the axis of the plug-in channel 310. In some other embodiments, the inner wall surface of the throat 311 can also be formed by the curved surface 313 arranged around the axis of the plug-in channel 310, that is, the inner wall surface of the plug-in channel 310 does not have edges and corners, for example, the opening formed by the throat 311 can be in the shape of an ellipse. In this way, the inner wall surface of the plug-in channel 310 does not have a convex-concave structure, which is easy to manufacture.

[0052] Please refer to Figure 5 and Figure 6The shape of the opening formed by the throat 311 is an oblong, including a straight portion located in the middle of the long axis direction and semicircular portions symmetrically arranged on both sides of the straight portion, the straight portion forming a plane 312, and the semicircular portion forming a curved surface 313. Due to the provision of the straight portion, the spacing between the two sides of the throat 311 provided with the straight portion is small, that is, the aperture size in the corresponding direction is small, while the spacing between the other two sides is large, that is, the aperture size in the corresponding direction is large, so that the two sides with smaller aperture sizes can form an interference fit with the atomizing matrix 400. When the atomizing matrix 400 is inserted, the side surfaces corresponding to the two sides with smaller aperture sizes of the throat 311 can be squeezed by the throat 311 to produce deformation, thereby achieving the purpose of fixing the atomizing matrix 400.

[0053] It should be noted that, in some other embodiments, the shape of the opening formed by the throat 311 may also be a polygon, for example, a triangle or a square. When the atomizing matrix 400 is inserted into the triangular throat 311, the parts corresponding to the three sides of the triangle on the outer peripheral surface of the atomizing matrix 400 can be squeezed and deformed, forming an interference fit with the throat 311. When the atomizing matrix 400 is inserted into the square throat 311, the parts corresponding to the four sides of the square on the outer peripheral surface of the atomizing matrix 400 can be squeezed and deformed, forming an interference fit with the throat 311. For the throat 311 with a square shape of the opening, the shape of the opening can be a square or a rectangle. Of course, in other embodiments, the shape of the opening formed by the throat 311 can also be other shapes, such as a regular pentagon or a regular hexagon.

[0054] If the atomizing matrix 400 directly contacts the throat 311 of the plug-in channel 310 when being inserted into the plug-in channel 310, the throat 311 may form a blockage on the end face of the atomizing matrix 400. Although the size of the portion where the blockage is formed is very small, it may also cause inconvenience in inserting the atomizing matrix 400. In one embodiment, in the axial direction of the plug-in channel 310, a guide section 314 is provided on the side of the throat 311 facing the outer end of the plug-in channel 310, and the inner wall surface of the guide section 314 is an inclined surface, and the inner diameter of the end of the guide section 314 close to the throat 311 is smaller than the end away from the throat 311. In this way, when the atomizing matrix 400 is inserted, the atomizing matrix 400 will not be directly blocked by the throat 311, but can be gradually deformed under the action of the inclined surface of the guide section 314, so as to facilitate the insertion of the atomizing matrix 400. In addition, a guide section 314 is also provided on one side of the throat 311 facing the inner end of the insertion channel 310 , and the guide section 314 on this side can facilitate the extraction of the atomized matrix 400 .

[0055] In one embodiment, the opening corresponding to the end of the guide section 314 away from the throat 311 is circular in shape, which can better guide the insertion of the atomized matrix 400.

[0056] The throat 311 may be located in the axial middle of the fixing body, and the two guide sections 314 may be arranged symmetrically relative to the atomizing substrate 400. This arrangement does not require distinguishing the installation direction of the atomizing substrate fixing 300, and is convenient for assembly.

[0057] It should be noted that, in some other embodiments, the atomized substrate fixing member 300 may also be in a form other than annular, for example, may be a cylindrical structure. In addition, the atomized substrate fixing member 300 may also be formed by a portion of the device housing 100 .

[0058] When in use, the atomizing matrix 400 is inserted from the matrix insertion port 120 at the top of the atomizing device. During the insertion process, the atomizing matrix 400 gradually enters the throat 311 under the guidance of the guide section 314 on the atomizing matrix fixing member 300. The portion of the atomizing matrix 400 corresponding to the direction of the smaller radial dimension of the throat 311 is gradually compressed and deformed radially, thereby forming an interference fit with the throat 311, and the shape of the atomizing matrix 400 gradually approaches the shape of the throat 311. After the atomizing matrix 400 is fully inserted into the atomizing device, a portion of the atomizing matrix 400 enters the atomizing core assembly 200. When the user inhales, the atomizing core assembly 200 heats the atomizing matrix 400 to generate an aerosol.

[0059] The above-mentioned atomized substrate fixing member 300 can fix the atomized substrate 400, and has a simple shape, which is convenient for molding and dimensional detection, and is beneficial for controlling product quality.

[0060] Embodiment of the atomized substrate fixing member in the utility model:

[0061] The structure of the atomizing substrate fixing member is the same as the structure of the atomizing substrate fixing member 300 in any embodiment of the atomizing device described above, and will not be described in detail here.

[0062] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
