Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, specifically a noise reduction axial flow fan mesh cover. Background Technology

[0002] Noise-reducing axial flow fans are axial flow fans that reduce noise generation through optimized design and the use of special materials. Their main features include low-noise design, high energy efficiency, and versatility in various applications. The primary function of the axial flow fan guard is to protect the fan blades, prevent foreign objects from entering the fan, and also guide airflow to ensure smooth circulation. Currently, existing axial flow fan guards typically lack a cleaning mechanism, requiring disassembly for cleaning, which affects the operation of the axial flow fan. Utility Model Content

[0007] A noise-reducing axial flow fan guard includes a guard body with ventilation holes. A rotating block is rotatably connected inside the guard body. Two connecting blocks are installed at one end of the rotating block. A lever is installed at the end of each of the two connecting blocks. A limiting component is provided on each of the two levers. Mounting blocks are installed on the upper and lower sides of one end of the guard body. Grooves are provided at the close ends of the two mounting blocks.

[0008] The limiting component includes a fixed block installed at one end of the lever, two sliding rods installed inside the fixed block, a slider slidably connected between the two sliding rods, a locking block installed at one end of the slider, the locking block being slidably connected to the fixed block, two springs installed at the bottom of the slider, both springs being connected to the fixed block, a through plate installed at one end of the slider, a handle installed at the bottom of the through plate, and the through plate being slidably connected to the fixed block.

[0009] Furthermore, the dial rotates within the ventilation hole.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a noise-reducing axial flow fan guard, which has the following beneficial effects:

[0013] This invention utilizes a rotating plate. As the rotating block rotates, the rotating plate is driven to rotate by the connecting block. The rotating plate cleans the ventilation holes by rotating, preventing dust and impurities from clogging them. After cleaning, the plate is limited by a limiting component to ensure stability and prevent shaking from affecting the heat dissipation and ventilation of the axial flow fan.

[0019] 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.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention provides a noise reduction axial flow fan screen, including a screen body 1, on which ventilation holes 2 are provided. A rotating block 3 is rotatably connected inside the screen body 1. Two connecting blocks 6 are installed at one end of the rotating block 3. A lever 7 is installed at the end of each of the two connecting blocks 6. A limiting component 8 is provided on each of the two levers 7. Mounting blocks 4 are installed on the upper and lower sides of one end of the screen body 1. Grooves 5 are provided at the close ends of the two mounting blocks 4. By rotating the lever 7, as the rotating block 3 rotates, the connecting blocks 6 drive the lever 7 to rotate. The lever 7 rotates within the ventilation holes 2 to clean, avoiding blockage by dust and impurities. After cleaning, the limiting component 8 limits the lever 7, thereby ensuring stability and preventing shaking from affecting the heat dissipation and ventilation of the axial flow fan.

[0022] The limiting component 8 includes a fixed block 81 installed at one end of the dial plate 7. Two slide rods 82 are installed inside the fixed block 81. A slider 83 is slidably connected between the two slide rods 82. A locking block 84 is installed at one end of the slider 83 and is slidably connected to the fixed block 81. Two springs 85 are installed at the bottom of the slider 83 and are connected to the fixed block 81. A through plate 86 is installed at one end of the slider 83 and a handle 87 is installed at the bottom of the through plate 86. The through plate 86 is slidably connected to the fixed block 81. By pulling the handle 87, the through plate 86 slides along the slide rods 82 with the slider 83, compressing the springs 85 and causing the locking block 84 to slide out of the groove 5. Then, the dial plate 7 can be rotated to clean the ventilation hole 2. After cleaning, as the springs 85 return to their original position, the locking block 84 is locked back into the groove 5 for limiting.

[0023] like Figure 1 As shown, in some embodiments, the toggle 7 rotates within the ventilation hole 2; this facilitates cleaning.

[0024] like Figure 4 As shown, in some embodiments, the locking block 84 slides within the groove 5; this facilitates positioning.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
