[0015] like Figures 1-8 As shown, this utility model provides a technical solution: a pluggable fan module with a filter, including a frame 1. The frame 1 is integrally injection molded from ABS engineering plastic and its surface is frosted. The frame 1 has three independent cavities along its length, which can simultaneously assemble three pluggable components 2 to improve heat dissipation efficiency. The pluggable components 2 are located inside the frame 1 and are used to realize the assembly of the fan and the filter.

[0016] like Figures 1-8 As shown in the embodiment of this application, the plug-in assembly 2 includes a filter plate 201, which is located in a cavity opened inside the frame 1. Arc-shaped plates 203 are provided at the four corners of the back side of the filter plate 201, and springs 205 are provided on the back side of the arc-shaped plates 203. The other end of the springs 205 is connected to the top plate 206. Hooks 202 are provided at the upper and lower ends of the back side of the top plate 206, and upright plates 204 are provided on the back side of the hooks 202. Specifically, the filter plate 201 is used to filter dust, hair, and other impurities in the air to prevent them from entering the equipment and affecting heat dissipation or damaging components. The filter plate 201 is a rectangular plate with a through-hole. A circular hole is provided, and a filter screen is installed inside the circular hole. The filter plate 201 is embedded in the vertical groove on the front frame 103. An arc-shaped plate 203 is provided on the back side of the filter plate 201. The arc-shaped plate 203 is fixedly connected to the front frame 103. The back side of the arc-shaped plate 203 is fixedly connected to the spring 205. The other end of the spring 205 is fixedly connected to the top plate 206. The top plate 206 is used to assist the hook 202 in fixing. The end of the hook 202 has a barb, which can achieve the connection with the front frame 103. The upright plate 204 on the back side of the hook 202 is located on the inner wall of the back side of the rear frame 104. It is used to abut against the fan, thereby limiting the fan.

[0017] like Figures 1-8As shown in the embodiment of this application, the frame 1 has three sets of cavities. The front and top inner walls of the cavities are provided with side plates 102. Specifically, the frame 1 has three sets of cavities, and the insertion and removal components 2 are assembled in the cavities. The front and top inner walls of each set of cavities of the frame are fixedly provided with side plates 102. The side plates 102 are rectangular plates and have regular octagonal holes. The side plates 102 at the top of the cavity are used to limit the hooks 202 and the filter plates 201 when the insertion and removal components 2 are assembled into the frame 1.

[0018] like Figures 1-8 As shown in the embodiment of this application, a front frame 103 and a rear frame 104 are provided in the cavity of the frame 1. A horizontal plate 101 is provided on the back side of the rear frame 104. The horizontal plate 101 is slidably connected to the frame 1. Specifically, the front frame 103 and the rear frame 104 can be combined with the cooperation of the hook 202 and the square hole to form a fan module. The fan module is installed into the cavity of the frame 1. The combination of the fan module and the frame 1 forms a fan plate. A sliding groove matching the horizontal plate 101 is opened at the rear of the frame 1. The horizontal plate 101 can slide back and forth along the sliding groove, thereby limiting the fan module installed in the frame 1 and improving the stability of the connection between the front frame 103 and the rear frame 104, preventing the fan inside from shifting when it is working. With the horizontal plate 101, it is easy to disassemble the fan module in the frame 1.

[0019] like Figures 1-8 As shown in the embodiment of this application, hooks 202 are symmetrically arranged at the upper and lower ends of the front side of the rear frame 104, and square holes are provided on the front frame 103 at positions corresponding to the hooks 202. The hooks 202 match the square holes. Specifically, each cavity of the frame 1 is provided with a front frame 103 and a rear frame 104. The front frame 103 is located at the front of the cavity, and the end face of the front frame 103 is arrayed with arc-shaped grooves. The arc-shaped grooves are in contact with the filter plate 201, thereby performing double filtration of impurities in the air. The rear frame 104 is located at the rear of the cavity, and a fan is pre-installed inside it. Hooks 202 are symmetrically arranged at the upper and lower ends of the front side of the rear frame 104, and square holes are provided at corresponding positions on the front frame 103. The hooks 202 match the square holes. With the square hole size matching, after placing the fan into the rear frame 104, push the front frame 103 towards the rear frame 104. Since the surface of the hook 202 facing the front frame 103 is curved, the front frame 103 will squeeze the hook 202. When the hook 202 enters the position of the square hole, the hook 202 is embedded in the square hole. The side of the hook 202 facing away from the square hole is flat, which can limit the connection of the hook 202 in the square hole. When disassembling the front frame 103 and the rear frame 104, you need to press the hook 202 down to complete the disassembly. If you pull the front frame 103 and the rear frame 104 horizontally to both sides, they will not separate due to the action of the flat surface of the hook 202.

[0020] like Figures 1-8 As shown in the embodiment of this application, a fan is pre-installed inside the rear frame 104, and a vertical plate 204 is provided on the back side of the fan. The vertical plate 204 is located on the inner wall of the back side of the rear frame 104 and abuts against the fan. Specifically, the end face of the rear frame 104 is provided with ventilation holes that match the fan to facilitate heat dissipation, and the end face is provided with screw holes that match the fan. The inner wall of the back of the rear frame 104 is provided with a vertical plate 204, and the vertical plate 204 is also provided with screw holes. With the screw holes, the stability of the connection between the fan and the rear frame 104 can be further improved. The space between the end face of the vertical plate 204 and the rear frame 104 is used to accommodate the fan.

[0021] The working principle of this utility model is as follows: First, assemble the front frame 103 and the rear frame 104. A vertical groove is provided near the end face of the front frame 103, extending downwards from the top to near the bottom. The vertical groove matches the filter plate 201. Insert the filter plate 201 into the vertical groove. The front and rear sides of the filter plate 201 are respectively attached to the arc-shaped groove on the end face of the front frame 103 and the front side of the arc-shaped plate 203. The arc-shaped plate 203 is fixed to the inner wall of the front frame 103, completing the initial assembly of the front frame 103. Then, push the fan through the opening on the back side of the rear frame 104. Inside the rear frame 104, after the fan is installed, the upright plate 204 is embedded into the inner wall of the back of the rear frame 104. To further improve the stability of the fan within the rear frame 104, the fan can be further secured using the screw holes and bolts on the fan, upright plate 204, and rear frame 104, thus completing the initial assembly of the rear frame 104. Pushing the front frame 103 towards the rear frame 104 will cause the hook 202 at one end of the rear frame 104 to push the top plate 206 to move horizontally along the inner wall of the front frame 103 away from the rear frame 104. During the translation of the top plate 206, the spring 205 is compressed. When the hook 202 enters the field of vision of the square hole on the front frame 103, the hook 202 matches the square hole and is embedded in the square hole, realizing the connection between the front frame 103 and the rear frame 104. The elastic force generated by the compression of the spring 205 acts in the opposite direction on the top plate 206, and the top plate 206 pushes the hook 202. However, since the side of the hook 202 facing away from the top plate 206 is flat, the hook 202 will not disengage from the square hole, that is, the front frame 103... It will not separate from the rear frame 104 and can help improve the stability of the connection between the front frame 103 and the rear frame 104. The fan module composed of the front frame 103 and the rear frame 104 is inserted into the cavity opened on the frame 1. After the fan module is installed, it slides horizontally into the horizontal plate 101 along the horizontal groove on the frame 1. The horizontal plate 101 is attached to the back side of the vertical plate 204, thereby limiting the position of the fan module in the frame 1 and improving the stability of the fan module in the frame 1, thus completing the assembly of the fan module and the frame 1.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
