[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a computer fan with an external module, including a mesh shell 1, a plurality of fan assemblies 4 are arranged on the inner side of the mesh shell 1, and adjustment components 2 are installed on both sides of the mesh shell 1. Two rubber top plates 5 are arranged between the two adjustment components 2 and above the mesh shell 1. The mesh shell 1 and the plurality of fan assemblies 4 are connected by a lifting buffer device 3, and the adjustment components 2 and the rubber top plates 5 are connected by an external blowing device 6.

[0023] Specifically, the lifting and buffering device 3 includes a lifting plate 31, a lead screw 32, a base plate 33, and a buffer assembly 35. The base plate 33 is provided below the mesh shell 1. The lead screw 32 is installed above the base plate 33 and on both sides of the two adjusting assemblies 2 via bearings. The lifting plate 31 is fixedly installed below the mesh shell 1 and on the outside of the two lead screws 32. The lifting plate 31 is connected to the multiple fan assemblies 4 via the buffer assembly 35.

[0024] By adopting the above technical solution, users can adjust the height of the mesh shell 1 by means of the cooperation of the lead screw 32 and the lifting plate 31 when needed, so as to better meet the working needs in different situations.

[0025] Specifically, the lifting and buffering device 3 also includes suction cups 34, and multiple suction cups 34 are fixedly installed under the bottom plate 33.

[0026] By adopting the above technical solution, the fan can be fixed in place by adsorption of each suction cup 34, thereby reducing the possibility of accidental movement and better meeting the needs of work.

[0027] Specifically, the buffer assembly 35 includes a small damper 351, a connecting frame 352, a support plate 353, and an elastic rubber block 354. The connecting frame 352 is fixedly installed on the outside of the multiple fan assemblies 4 and on the inside of the mesh shell 1. The support plate 353 is fixedly installed on both sides of the connecting frame 352 and on the inside of the mesh shell 1. Two elastic rubber blocks 354 are fixedly installed between the lifting plate 31 and the two support plates 353. Multiple small dampers 351 are fixedly installed between the lifting plate 31, the two support plates 353, and the connecting frame 352 and between the two elastic rubber blocks 354.

[0028] By adopting the above technical solution, the fan can buffer the vibration generated by the fan assembly 4 during operation through the cooperation of structures such as the small damper 351 and the elastic rubber block 354, thereby reducing the possibility of adverse effects on the operation.

[0029] In this embodiment, when the computer needs to use fans for cooling, the user places the fans in the working position. The suction cups 34 under the base plate 33 of the lifting buffer device 3 adhere to the floor or other structures where the fans are located. Then, the user rotates the two lead screws 32 simultaneously. The two lead screws 32 are threadedly connected to the lifting plate 31, so the two lead screws 32 drive the lifting plate 31 to move, thereby adjusting the height of the mesh shell 1 and other structures. Then, the user places the computer host on the mesh shell 1, manipulates the two adjustment components 2 to drive the two rubber top plates 5 to clamp the computer host, and then starts the various fan components 4 to blow air, thereby cooling the computer host. The two elastic rubber blocks 354 and various small dampers 351 in the buffer component 35 can buffer the vibration generated by the various fan components 4 when they are working. The connecting frame 352 and the support plate 353 play a supporting role.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the external blower 6 includes a connecting box 61, a mesh box 63 and an auxiliary fan 64. The adjustment component 2 and the rubber top plate 5 are connected through the connecting box 61. The mesh box 63 is provided inside the connecting box 61, and the auxiliary fan 64 is fixedly installed inside the mesh box 63.

[0032] By adopting the above technical solution, users can use the mesh box 63 and auxiliary fan 64 to dissipate heat from areas on the computer host that are difficult to be vented by the fan assembly 4 when needed, thereby better meeting the work needs in different situations.

[0033] Specifically, the external blower device 6 also includes a cover plate 62 and a connecting rope 65. The cover plate 62 is installed on the top of the connecting box 61 via a hinge, and the connecting box 61 and the mesh box 63 are connected by the connecting rope 65.

[0034] By adopting the above technical solution, the user can close the connection box 61 through the cover plate 62, thereby reducing the possibility of external impurities entering the connection box 61. The connecting rope 65 plays a role in preventing the mesh box 63 and the auxiliary fan 64 inside from being lost.

[0035] In this embodiment, when it is necessary to dissipate heat in areas of the computer host where the fan assembly 4 is difficult to blow air, the user opens the cover 62 of the two external blowers 6, takes out the mesh box 63 from the two connecting boxes 61, places it in a position to align with the area that needs heat dissipation, and starts the auxiliary fan 64 in the two mesh boxes 63 to blow air, thereby dissipating heat in areas of the computer host where the fan assembly 4 is difficult to blow air. The connecting rope 65 serves to prevent loss.

[0036] The structure and principle of the mesh shell 1, the adjusting assembly 2 consisting of a first connecting rod, a fixing rod, a screw rod, a pushing ball, a base, a second connecting rod, a bottom plate, and an adsorption spring, the fan assembly 4 consisting of a heat sink, heat dissipation holes, screw holes, a fan screw, a fan, a fan clip device, a fixing plate, a pin, a concave clip plate, and a convex clip plate, and the rubber top plate 5 in this utility model have been disclosed in a computer fan using an external device to accelerate heat dissipation in Chinese patent application number 202123162531.5. Its working principle involves placing the rubber top plate on both sides of the host computer, adjusting the fan position through a roughly visible location, and then tightening the screw rod so that the pushing ball moves along the bottom of the base. The sliding groove of the part is pushed downwards, and the base is fixedly connected to the bottom of the second connecting rod, so the second connecting rod will push the base plate upwards. The second connecting rod is rotatably connected to the first connecting rod. Then the base plate will be compressed by the pressure of the two ends of the pressure adsorption spring, and the rubber top plate will be clamped to hold the host, thereby aligning the fan with the computer's air outlet. Then the fan is installed on the top of the heat sink and secured with fan screws. The fixing plate inside the fan clip device is fixedly installed inside the heat sink and secured by a pin. The concave clip is fixedly installed on the left side of the fixing plate, and then the convex clip is snapped into the inside of the concave clip. The internal drive device drives the fan to achieve the heat dissipation effect.

[0037] The structure and principle of the small and medium-sized damper 351 of this utility model have been disclosed in a micro box device for computer network security disclosed in Chinese patent application No. 202020567163.9. Its working principle consists of a piston and an oil tank, which is filled with oil. When an object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0038] The working principle and usage process of this utility model are as follows: When the computer needs to use a fan for cooling, the user places the fan in the working position. The suction cups 34 under the base plate 33 of the lifting buffer device 3 adhere to the floor or other structures where the fan is located. Then, the two lead screws 32 are rotated simultaneously. The two lead screws 32 are threadedly connected to the lifting plate 31, so the two lead screws 32 drive the lifting plate 31 to move, thereby adjusting the height of the mesh shell 1 and other structures. Then, the user places the computer host on the mesh shell 1, manipulates the two adjusting components 2 to drive the two rubber top plates 5 to clamp the computer host, and then starts the various fan components 4 to blow air, thereby cooling the computer host. For heat dissipation, the two elastic rubber blocks 354 and each small damper 351 in the buffer assembly 35 can buffer the vibration generated by each fan assembly 4 when it is working. The connecting frame 352 and the support plate 353 play a supporting role. When it is necessary to dissipate heat in the parts of the computer host where the fan assembly 4 is difficult to blow air, the user opens the cover plate 62 in the two external blowers 6 respectively, takes out the mesh box 63 in the two connecting boxes 61 respectively, places it in place, aligns it with the part that needs to be dissipated, and starts the auxiliary fan 64 in the two mesh boxes 63 to blow air, thereby dissipating heat in the parts of the computer host where the fan assembly 4 is difficult to blow air. The connecting rope 65 plays a role in preventing loss.

[0039] 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 claims and their equivalents.
