DETAILED DESCRIPTION

[0037] One of the cores of the present application is to provide an atomizing device, the structural design of which can avoid leakage and sealing problems.

[0038] Another core of the present application is to provide an electronic atomization device including the above-mentioned atomization device.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the atomization device provided in an embodiment of the present application.

[0041] An atomizer device is disclosed in an embodiment of the present application. The atomizer device generally includes a shell 1 and a suction nozzle 2 arranged at one end of the shell 1. A cavity can be formed in the shell 1, and the cavity is connected to the suction nozzle 2. The cavity is used to accommodate a battery, an atomizer component and a liquid storage component. After the battery is energized for the atomizer component, the atomizer component generates heat to atomize the liquid atomization matrix in the liquid storage component into an aerosol. The user inhales the generated aerosol through the suction nozzle 2. It can be seen that in order to place the battery, the atomizer component and the liquid storage component into the shell 1, the shell 1 must include a plurality of connected shells. During use, the gaps between the shells are prone to leakage and sealing problems. Therefore, in the present application, the structure of the connection between the two shells is improved, such as Figures 2 to 4 As shown, the atomization device includes a first shell 1A and a second shell 1B.

[0042] Among them, the first shell 1A includes a first main body portion 110 and a first connecting portion 111. The first connecting portion 111 is arranged on the first main body portion 110. The first connecting portion 111 is a portion extending from the first main body portion 110. The first main body portion 110 and the first connecting portion 111 can be a solid structure or a hollow structure, thereby forming a cavity for accommodating other components.

[0043] The second shell 1B includes a second main body portion 120 and a first matching portion 121. The first matching portion 121 is arranged on the second main body portion 120. Similar to the above-mentioned first shell 1A, the first matching portion 121 is a portion extending from the second main body portion 120. The second main body portion 120 and the first matching portion 121 can be a solid structure or a hollow structure, thereby forming a cavity for accommodating other components.

[0044] The first shell 1A and the second shell 1B are connected by interference fit between the first connecting portion 111 and the first matching portion 121 and by plug-in. It should be noted that when the first connecting portion 111 and the first matching portion 121 are connected by plug-in, the first connecting portion 111 can be inserted into the first matching portion 121, that is, the first connecting portion 111 is plug-in-fitted with the inner circumferential surface of the first matching portion 121 through the outer circumferential surface, such as Figures 2 to 4 The embodiment shown; in other embodiments, the first connection portion 111 may be surrounded by the first matching portion 121, that is, the first connection portion 111 is inserted and matched with the outer circumferential surface of the first matching portion 121 through the inner circumferential surface. The first shell 1A and the second shell 1B can be tightly matched by interference, and the interference connection is relatively firm; the plug-in connection can make the glue diffuse along the radial direction of the atomizing device, evenly diffuse in the first overflow glue space 1C, and then evenly distributed in the overflow glue groove 113, ensuring the adhesive fixing effect between the first shell 1A and the second shell 1B.

[0045] At least one of the first connecting portion 111 and the first matching portion 121 is provided with a recessed first glue overflow portion 112 at the matching connection, that is, at least one of the matching surfaces of the first connecting portion 111 and the first matching portion 121 is provided with a recessed first glue overflow portion 112. Among them, at least one side of the first glue overflow portion 112 is formed with a matching surface, at least one matching surface is the matching connection between the first connecting portion 111 and the first matching portion 121, the matching connection can be the outer side of the first connecting portion 111, and the first glue overflow portion 112 can be the inner side of the first matching portion 121, such as Fig.11 As shown, it may refer to the position indicated by the first connection portion 111, the first glue overflow portion 112 and the glue overflow groove 113; accordingly, the mating surface is the outer surface of the first connection portion 111, such as Fig.14 As shown, it may be the position indicated by the first matching portion 121. When the matching surfaces of the first connecting portion 111 and the first matching portion 121 are both provided with a recessed first glue overflow portion 112, after being inserted and matched in place, the first glue overflow portion 112 of the first connecting portion 111 and the first glue overflow portion of the first matching portion 121 may be arranged opposite to each other or offset, and the shapes and sizes of the first glue overflow portion 112 of the first connecting portion 111 and the first glue overflow portion of the first matching portion 121 may be the same or different, and the first glue overflow portion 112 includes but is not limited to the forms of a groove, a hole, etc., and a first glue overflow space 1C is formed between the matching surfaces of the first connecting portion 111 and the first matching portion 121 through the first glue overflow portion 112, as shown in FIG. Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, one or more first glue overflow spaces 1C may be formed between the first connecting portion 111 and the first matching portion 121 .

[0046] When the first glue overflow part 112 adopts a groove structure, the first glue overflow part 112 may include one or more grooves. The grooves may be arranged horizontally, that is, perpendicular to the insertion direction of the first shell 1A and the second shell 1B, or vertically, that is, along the insertion direction of the first shell 1A and the second shell 1B. In the case where the grooves are arranged horizontally or vertically, the grooves may be densely arranged so that the circumferential surface of the first connecting part 111 or the first matching part 121 forms a wavy structure. During assembly, glue may be applied at the crest of the wavy structure. After insertion and matching, the first glue overflow part is formed by the trough of the wavy structure. Of course, both horizontal and vertical arrangements may be adopted at the same time to form a horizontal and vertical cross structure. Of course, the grooves may also intersect with the insertion direction but not perpendicular. When the first glue overflow part 112 adopts a hole structure, the first glue overflow part 112 preferably includes a plurality of holes arranged circumferentially along the first connecting part 111 or the first matching part 121, or the holes may be connected by the grooves. Of course, the first glue overflow part 112 may also include a hole structure and a groove structure at the same time, which is not limited here.

[0047] It can be seen that compared with the prior art, when the atomization device provided in the embodiment of the present application is used, glue can be dispensed on the first glue overflow part 112, and then the first connecting part 111 of the above-mentioned first shell 1A and the first matching part 121 of the second shell 1B are plugged and matched. During the matching process, the matching surface between the first connecting part 111 and the first matching part 121 squeezes the glue, so that the glue diffuses along the matching surfaces of the two, and the excess glue enters the first glue overflow space 1C, thereby avoiding glue overflow, eliminating the glue drying process in the existing assembly link, and improving the product assembly quality and assembly efficiency. At the same time, the connection strength and sealing and waterproof performance between the first shell 1A and the second shell 1B can be increased to avoid leakage and sealing problems during use.

[0048] The first glue overflow portion 112 can be in the form of a complete ring surrounding the first connecting portion 111 or the first matching portion 121, or can be in the form of a strip surrounding a local position on the circumference of the first connecting portion 111 or the first matching portion 121, that is, in the embodiment of the present application, the first glue overflow portion 112 is at least partially arranged around the first connecting portion 111 or the first matching portion 121, and along the insertion direction, one side or both sides of the first glue overflow portion 112 are formed as matching surfaces.

[0049] One or more first glue overflow portions 112 may be provided on the first connecting portion 111 and / or the first matching portion 121. When there are multiple first glue overflow portions 112, the length, width and depth of each first glue overflow groove 113 may be the same or different, and each first glue overflow portion 112 may be arranged at intervals along the circumference of the first connecting portion 111, or each first glue overflow portion 112 may be arranged in a staggered manner along the insertion direction, that is, at least one end of the two first glue overflow portions 112 may overlap along the insertion direction, and the remaining parts may not overlap, so as to ensure that the first glue overflow portions 112 are arranged on the entire circumference of the first connecting portion 111 and / or the first matching portion 121.

[0050] Further, in order to increase the overflow volume, at least one side of the first overflow portion 112 is provided with an overflow groove 113 extending along the insertion direction, and a plurality of overflow grooves 113 are arranged at intervals along the first overflow groove 113. The shapes of the overflow grooves 113 include but are not limited to rectangle, triangle, trapezoid, and arc. The overflow grooves 113 are arranged at intervals along the first overflow portion 112, such as Figures 9 to 12 shown.

[0051] In one embodiment of the present application, Fig.11 As described, the first glue overflow portion 112 is formed on the outer peripheral surface of one end of the first connecting portion 111 away from the first main body portion 110. Therefore, a plurality of trapezoidal glue overflow grooves 113 are arranged at intervals along the circumference of the first connecting portion 111 on one side of the first glue overflow portion 112 close to the first main body portion 110 to form a tooth-shaped structure. The depth of the glue overflow groove 113 can be the same as the depth of the first glue overflow portion 112. Of course, the depth of the glue overflow groove 113 can also decrease with the increase of the distance from the first glue overflow portion 112, that is, an inclined slope is formed in the glue overflow groove 113 to facilitate the glue to enter and exit the first glue overflow portion 112.

[0052] During the insertion and matching process between the first housing 1A and the second housing 1B, it is necessary to limit the matching degree between the two to prevent excessive or inadequate insertion. Figure 4 , Figure 6 and Figures 11 to 13 As shown, a first limiting step surface 114 is arranged between the first connecting portion 111 and the first main body portion 110, and the first limiting step surface 114 is used to contact and cooperate with the end surface 122 of the second shell 1B; and / or, the second shell also includes a second main body portion 120, and a second limiting step surface is arranged between the first matching portion 121 and the second main body portion 120, and the second limiting step surface is used to contact and cooperate with the end surface of the first connecting portion 111.

[0053] from Figure 4 , Figure 6 and Figures 11 to 13It can be seen that in this embodiment, the first connecting portion 111 of the first shell 1A is inserted into the first matching portion 121 of the second shell 1B, so the first limiting step surface 114 is located on the outside of the first shell 1A. If in other embodiments, the first connecting portion 111 of the first shell 1A is surrounded by the first matching portion 121 of the second shell 1B, the first limiting step surface 114 can be set on the inside of the first shell 1A. Of course, similarly, a second limiting step surface can also be set between the first matching portion 121 of the second shell 1B and the second main body 120 to cooperate with the end face of the first connecting portion 111, so as to limit the degree of insertion and fitting between the first shell 1A and the second shell 1B, and ensure that the first shell 1A and the second shell 1B are assembled in place.

[0054] It is foreseeable that, due to the interference fit between the first shell 1A and the second shell 1B, the glue will inevitably be pushed to the first limiting step surface 114 and / or the second limiting step surface during the insertion process. If the amount of glue is large, the glue will overflow from the first limiting step surface 114 and / or the second limiting step surface. To avoid this situation, Figure 4 and Figure 6 As shown, at least one of the first limiting step surface 114 and the end surface of the first matching portion 121 is provided with a recessed second overflow glue portion 115, and a second overflow glue space 1D is formed between the first limiting step surface 114 and the end surface of the first matching portion 121 through the second overflow glue portion 115, and / or, at least one of the second limiting step surface and the end surface of the first connecting portion 111 is provided with a recessed third overflow glue portion, and a third overflow glue space is formed between the second limiting step surface and the end surface of the first connecting portion 111 through the third overflow glue portion, so that during the assembly process, the first shell 1A and the second shell 1B are pushed toward the first limiting step surface during the interference plugging process. The glue on the step surface 114 will enter the second glue overflow space 1D, thereby forming an adhesive seal between the end face of the first matching portion 121 of the second shell 1B and the first limiting step surface 114, and / or, the glue pushed toward the second limiting step surface during the interference fit between the first shell 1A and the second shell 1B will enter the third glue overflow space, thereby forming an adhesive seal between the end face of the first connecting portion 111 of the first shell 1A and the second limiting step surface, thereby further improving the connection strength and sealing and waterproof effect between the first shell 1A and the second shell 1B, and effectively preventing glue overflow, which can further improve the product assembly quality.

[0055] like Figure 4 and Figure 6As shown, the end face of the first matching portion 121 is provided with a first limiting boss 124 for cooperating with the second overflow glue portion 115, and the first limiting boss 124 is used to be inserted into the second overflow glue portion 115, and / or the end face of the first connecting portion 111 is provided with a second limiting boss for cooperating with the third overflow glue portion. By providing the first limiting boss 124 and / or the second limiting boss, the bonding area between the first shell 1A and the second shell 1B can be increased, so that the first shell 1A and the second shell 1B can be more closely matched, and the connection strength can be increased. At the same time, it can also avoid the surfaces of the first shell 1A and the second shell 1B from warping and deforming asynchronously relative to each other when under pressure, and avoid the formation of gaps between the first shell 1A and the second shell 1B, which affects the sealing and waterproofing effect.

[0056] like Figure 4 and Figure 6 As shown, along the insertion direction, the second glue overflow portion 115 is located within the projection of the end face of the first matching portion 121 on the first limiting step face 114, and / or, along the insertion direction, the third glue overflow portion is located within the projection of the end face of the first connecting portion 111 on the second limiting step face, that is, the width of the second glue overflow portion 115 and the width of the third glue overflow portion are smaller than the width of the end face of the first matching portion 121 or the end face of the first connecting portion 111, so as to ensure that the end face of the first matching portion 121 or the end face of the first connecting portion 111 can cover the second glue overflow portion 115 or the third glue overflow portion, so as to avoid the second glue overflow portion 115 and the third glue overflow portion being exposed after assembly, so as to avoid glue overflow and also avoid gaps and steps on the surface of parts after assembly.

[0057] Since other parts may be arranged inside the first shell 1A and the second shell 1B, the first shell 1A and the second shell 1B must be inserted and assembled according to the preset relative positions when they are inserted and assembled. In order to avoid assembly errors that affect the functions of the parts inside the first shell 1A and the second shell 1B, in one embodiment of the present application, as Figure 4 , Fig.11 , Figures 14 to 16 As shown, the first main body 110 of the first shell 1A is provided with a second connecting portion 116, and the second connecting portion 116 is asymmetrically arranged along the circumference of the first shell; the second main body 120 of the second shell 1B is provided with a second matching portion 123, and the second matching portion 123 is asymmetrically arranged along the circumference of the second shell 1B; the second connecting portion 116 is used to match with the second matching portion 123, and the second connecting portion 116 is used to match with the second matching portion 123 of the second shell 1B. The second connecting portion 116 cooperates with the second matching portion 123 to ensure that the first shell 1A and the second shell 1B can be plugged and matched according to a preset relative position, and there is no need to identify the positions of the parts inside the first shell 1A and the second shell 1B during the assembly process and then assemble them accordingly, which can effectively improve the assembly efficiency.

[0058] Specifically, in one embodiment of the present application, Figure 4 , Fig.11 and Figures 14 to 16 As shown, one of the second connecting portion 116 and the second matching portion 123 is a concave portion sunken along the insertion direction, and the other is a convex portion matched with the concave portion.

[0059] like Figure 4 , Figure 5 and Fig.11 As shown, a guide slope 117 is provided at one end of the first connecting portion 111 of the first shell 1A away from the first main body portion 110, and / or a guide slope 117 is provided on the end surface of the first matching portion 121 of the second shell 1B, so as to guide the first shell 1A and the second shell 1B during the insertion process for easy insertion.

[0060] The present application also provides an electronic atomization device, such as Fig.17 As shown, the electronic atomization device includes an atomization device and a charging device 3, wherein the atomization device is the atomization device as described in the embodiment, and the atomization device is used to heat the atomization matrix into an aerosol; the charging device 3 is detachably connected to the atomization device, and the charging device 3 is used to charge the battery in the atomization device.

For a disposable atomization device, the atomization device and the charging device 3 are fixedly connected; for a replaceable cartridge atomization device, the atomization device and the charging device 3 are detachably connected, and the atomization device and the charging device 3 can be replaced according to usage.

[0061] Furthermore, in a specific embodiment of the present application, the atomization device and the charging device 3 are magnetically connected, the atomization device includes a first magnetic component, the charging device 3 includes a second magnetic component, and the atomization device and the charging device 3 are magnetically connected via the first magnetic component and the second magnetic component.
