[0039] Desiccant is an essential dehumidification unit inside the camera. In existing cameras, desiccant is usually fixed by double-sided tape, fixed by cable ties, or spread in the internal cavity of the camera according to process documents. However, when fixed by double-sided tape, the double-sided tape itself has a sticky period, which can easily cause the desiccant to be touched and fall off during assembly or use; when fixed by cable ties, the cable ties or other structures in the camera can easily cause the outer packaging of the desiccant to be punctured; when spread according to process documents, the proficiency of the production line workers is required to be high. Therefore, these existing fixing methods are likely to cause the desiccant to move inside the camera and produce abnormal noise, affecting the user experience.

[0040] In order to solve the above problems, Figures 1 to 7 As shown, the utility model provides a camera to improve the fixing effect of the desiccant and prevent the desiccant from moving inside the camera and generating abnormal noise.

[0041] like Figure 1 and Figure 3As shown, specifically, the camera includes a shell 1 and a desiccant box 2 arranged in the shell 1, and the desiccant box 2 includes a shell 21, a cover 22, a support member 23 and an elastic member 24, wherein: the shell 21 includes a plurality of side walls 216 and has a first opening 211, at least one side wall 216 is set as a solid structure, and the other side walls 216 are provided with through holes connected to the internal space of the shell 1; the cover 22 is openably set in the first opening 211; the support member 23 is slidably set in the shell 21 and is arranged parallel to the side wall 216 of the solid structure, and a side surface of the support member 23 facing away from the side wall 216 of the solid structure is surrounded by the shell 21 and the cover 22 to form a storage space for storing the desiccant 3; the two ends of the elastic member 24 are respectively against the support member 23 and the side wall 216 of the solid structure, and can be compressed when the support member 23 slides toward the side wall 216 of the solid structure.

[0042] Wherein, the side wall 216 of the shell 21 includes a first side wall 2161 opposite to the first opening 211, and a plurality of second side walls 2162 adjacent to the first side wall 2161 and surrounding the first opening 211. When the desiccant box 2 is set as a rectangular parallelepiped structure as shown in the figure, the first side wall 2161 is a rectangular structure, and the first opening 211 is formed by surrounding four second side walls 2162. Of course, the desiccant box 2 can also be set as a triangular prism structure, a pentagonal prism structure or other regular or irregular shaped structures, as long as it can be surrounded to form a storage space for accommodating the desiccant 3, the embodiment of the utility model is not specifically limited here. In addition, the solid structure is a structure without a through hole to ensure the stability and reliability of the support of the elastic member 24, the support member 23 and the desiccant 3.

[0043] In the camera provided by the embodiment of the utility model, the cover body 22 is first opened, and the desiccant 3 is placed in the storage space of the desiccant box 2 through the first opening 211, and then the cover body 22 is closed, so that the support member 23 slides toward the side wall 216 of the solid structure, the elastic member 24 is compressed, and can apply an elastic force toward the side of the desiccant 3 to the support member 23, so that the support member 23 can cooperate with the shell 21 or the cover body 22 to limit the desiccant 3, so as to prevent the desiccant 3 from moving in the storage space and making abnormal noise; then the desiccant box 2 and the desiccant 3 are placed in the shell 1 as a whole, and the desiccant 3 can realize air circulation with the internal space of the shell 1 through the through holes on the side wall 216, so as to dry and dehumidify the internal space of the shell 1, and ensure the good working performance of the camera; the desiccant box 2 and the desiccant 3 form a modular structure, which is easy to install, and the desiccant box 2 can also protect the desiccant 3, so that the desiccant 3 is fully wrapped, so as to prevent other structures inside the camera from piercing the outer packaging of the desiccant 3.

[0044] It is understandable that cameras of different models or different applicable environments have different requirements for the weight and quantity of the desiccant 3. In the desiccant box 2 provided in the embodiment of the utility model, since the size of the accommodating space can be changed when the support member 23 slides, it can accommodate desiccants 3 of different weights or quantities, so that the desiccant box 2 can be used in cameras of different models or different applicable environments, and has a wide range of applications.

[0045] like Figure 3 to Figure 4 As shown, at least one side wall 216 is set as a solid structure, and the other side walls 216 are set as a mesh structure to form the through hole. The side wall 216 of the mesh structure has a certain flexibility and deformation ability, which can increase the capacity of the desiccant 3. When a large number of desiccant 3 is contained in the containing space, the side wall 216 of the mesh structure also allows the desiccant 3 and the side wall 216 to be evenly stressed, ensuring the overall strength of the desiccant box 2 and the desiccant 3, and preventing the desiccant 3 from being crushed or the desiccant box 2 from being crushed.

[0046] The mesh structure may be a "cross" or "M" shaped structure, or may be a pentagonal, hexagonal or other regular or irregular shaped structure, as long as the storage space of the desiccant box 2 can be connected to the internal space of the housing 1, and the embodiment of the utility model is not specifically limited here.

[0047] like Figures 2 to 3 As shown, in the illustrated embodiment, the side wall 216 opposite to the first opening 211 is set as a solid structure, and the other side walls 216 are all set as a mesh structure. That is, the first side wall 2161 is set as a solid structure, and the second side wall 2162 is set as a mesh structure. The support member 23 is arranged in parallel with the first side wall 2161 and the cover body 22, and can slide close to or away from the first side wall 2161 to increase or reduce the accommodation space. The desiccant 3 can achieve air circulation with the internal space of the shell 1 through the second side wall 2162. Since the number and area of ​​the second side wall 2162 are large, the air circulation between the desiccant 3 and the internal space of the shell 1 is good, so as to ensure the drying and dehumidification effect of the desiccant 3 on the internal space of the shell 1. Since the first side wall 2161 is arranged relative to the first opening 211, it is also convenient for the user to take or place the desiccant 3, and the operation is convenient.

[0048] In another embodiment, one of the second side walls 2162 may be set as a solid structure, and the first side wall 2161 and the remaining second side walls 2162 may be set as a mesh structure. The support member 23 is arranged parallel to the second side wall 2162 of the solid structure, and is arranged vertically to the first side wall 2161 and the cover body 22, and can slide close to or away from the second side wall 2162 to increase or decrease the accommodation space. Of course, in other embodiments, when the first side wall 2161 is set as a solid structure, part of the second side wall 2162 may also be set as a solid structure; when one of the second side walls 2162 is set as a realization structure, the first side wall 2161 or part of the second side wall 2162 may also be set as a solid structure. As long as at least one side wall 216 is set as a mesh structure, so that the desiccant 3 can achieve air circulation with the internal space of the housing 1 through the side wall 216 of the mesh structure, the embodiment of the utility model is not specifically limited here.

[0049] like Figure 3 and Figure 5 As shown, one side of the cover 22 is rotatably connected to the housing 21, and the other side of the cover 22 is detachably connected to the housing 21. The opening and closing method of the cover 22 is simple and convenient, which is convenient for users to operate, and in the process of taking or placing the desiccant 3, the cover 22 will not fall off the housing 21, avoiding the loss of parts.

[0050] like Figures 5 to 7 As shown, a rotating shaft 222 is provided on one side of the cover 22 that is rotatably connected to the shell 21, and the cover 22 is rotatably connected to the shell 21 via the rotating shaft 222. A clamping portion 221 is provided on one side of the cover 22 that is clamped to the shell 21, and a clamping member 212 that can be clamped and matched with the clamping portion 221 is provided at one end of the shell 21 close to the first opening 211. The clamping and disassembly methods of the clamping portion 221 and the clamping member 212 are simple, and in the closed state, the clamping portion 221 can be stably clamped with the clamping member 212 to ensure the stability and reliability of the connection between the cover 22 and the shell 21, and to prevent the cover 22 from accidentally opening and causing the desiccant 3 in the accommodating space to fall.

[0051] The clamping member 212 may be disposed on the inner wall of the second side wall 2162 near the first opening 211, or may be disposed on the outer wall of the second side wall 2162 near the first opening 211, or may be protruded from the edge of the second side wall 2162 facing the first opening 211. The clamping portion 221 is disposed correspondingly to the clamping member 212, as long as it can be clamped and matched with the clamping member 212.

[0052] like Figure 6 to Figure 7As shown, in the open state, the first guide surface 2121 is provided on the side of the clamping member 212 facing the clamping portion 221. The second guide surface 2211 is provided on the side of the clamping portion 221 facing the clamping member 212. In the process of closing the cover body 22, the first guide surface 2121 and the second guide surface 2211 are slidably matched and play a guiding role, so that the clamping portion 221 and the clamping member 212 can be mutually engaged after slight deformation, which is more labor-saving and convenient for users to close the cover body 22. Of course, only the clamping member 212 is provided with the first guide surface 2121, or only the clamping portion 221 is provided with the second guide surface 2211, which can also play a guiding and labor-saving role when closing the cover body 22.

[0053] like Figures 5 and 6 As shown, along the depth direction of the shell 21, the shell 21 is further provided with an abutment member 213 spaced apart from the clamping member 212. In the closed state, the clamping portion 221 is clamped between the clamping member 212 and the abutment member 213. The depth direction of the shell 21 is the spacing direction between the cover 22 and the first side wall 2161. The abutment member 213 can limit the rotation angle of the cover 22 relative to the shell 21, and prevent the cover 22 from turning over excessively toward the inside of the shell 21. In addition, in the closed state, the clamping member 212 and the abutment member 213 are respectively located on both sides of the clamping portion 221, which can also improve the stability and reliability of the cover 22.

[0054] like Figures 5 and 6 As shown, when the clamping member 212 is disposed on the inner wall of the second side wall 2162 close to one end of the first opening 211, the cover body 22 is embedded in the first opening 211, and the end of the shell 21 close to the first opening 211 is further provided with an escape opening 214 corresponding to the clamping portion 221. The user can move the clamping portion 221 through the escape opening 214, so that the clamping portion 221 is disengaged from the clamping member 212, and the cover body 22 is rotated relative to the shell 21 to open, so as to facilitate the user's operation.

[0055] like Figure 1 to Figure 2 As shown, the inner wall of the housing 1 is provided with a limit assembly 11, and the desiccant box 2 is detachably connected to the limit assembly 11. The limit assembly 11 can limit the position of the desiccant box 2 in the housing 1 to prevent the desiccant box 2 from sliding relative to the housing 1, thereby preventing the desiccant box 2 from sliding relative to the housing 1 and causing the desiccant 3 to make an abnormal sound or affect the normal operation of other structures in the housing 1. The desiccant box 2 is detachably connected to the limit assembly 11 so that the user can regularly remove the desiccant box 2 and replace the desiccant 3.

[0056] like Figure 1 , Figure 2 and Figure 6As shown, the limiting assembly 11 includes a limiting member 111 and a first limiting rib 112 spaced apart from the limiting member 111. A limiting groove 1111 is provided on the side of the limiting member 111 facing the first limiting rib 112. Part of the desiccant box 2 is clamped in the limiting groove 1111. The outer wall of the housing 21 is provided with a second limiting rib 215 that can be clamped and matched with the first limiting rib 112. When installing the desiccant box 2, the desiccant box 2 is first inserted into the limiting groove 1111 toward the limiting member 111, and then the second limiting rib 215 is clamped with the first limiting rib 112, so that the desiccant box 2 is fixed relative to the limiting member 111 and the housing 1. The first limiting rib 112 cooperates with the second limiting rib 215 to prevent the desiccant box 2 from accidentally falling out of the limiting groove 1111, thereby improving the stability and reliability of the connection between the desiccant box 2 and the limiting assembly 11. When disassembling the desiccant box 2, first move the desiccant box 2 to the side away from the first limiting rib 112, so that the second limiting rib 215 is separated from the first limiting rib 112, and then pull the desiccant box 2 out of the limiting groove 1111 to the side away from the limiting member 111. The disassembly and assembly method is simple and convenient, and is easy for users to operate. In the assembled state, at least part of the side wall 216 of the mesh structure is exposed to the limiting groove 1111 to ensure that the desiccant 3 can achieve air circulation with the internal space of the housing 1.

[0057] In the illustrated embodiment, the limiting member 111 includes a first limiting wall 1112 arranged opposite to one side inner wall of the housing 1 and two second limiting walls 1113 arranged opposite to and adjacent to the inner wall of the housing 1, and the first limiting wall 1112, the two second limiting walls 1113 and the inner wall of the housing 1 are arranged to form a limiting groove 1111. Of course, in other embodiments, the limiting member 111 may also include a plurality of limiting walls, and the plurality of limiting walls are arranged to form a limiting groove 1111 corresponding to the shape of the desiccant box 2.

[0058] like Figure 1 and Figure 3 As shown, in the illustrated embodiment, the housing 1 is provided with a second opening 12, and in the assembled state, the first opening 211 faces the second opening 12. The first side wall 2161 and the cover body 22 are arranged parallel to the second opening 12, and the second side wall 2162 is arranged perpendicular to the second opening 12. Thus, the user can open the cover body 22 and replace the desiccant 3 without disassembling the desiccant box 2, and the operation is more convenient. Among them, the limiting member 111 and the first limiting rib 112 can be arranged at intervals along the depth direction of the housing 1, that is, the first limiting rib 112 is located on the side of the limiting member 111 close to the second opening 12, so as to facilitate the user to disassemble and assemble the desiccant box 2. Alternatively, the limiting member 111 and the first limiting rib 112 can also be arranged at intervals along the direction of the opening size of the second opening 12, that is, the limiting member 111 and the first limiting rib 112 are arranged at intervals on the inner wall opposite to the second opening 12.

[0059] In other embodiments, in the assembled state, the first opening 211 faces the inner wall of the housing 1. At least one second side wall 2162 is arranged parallel to the second opening 12, and the first side wall 2161 and the cover 22 are arranged perpendicular to the second opening.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
