Description

Technical Field

[0001] This utility model relates to the field of fan processing technology, specifically a noise-reducing fan guard. Background Technology

[0002] Currently, the primary function of fan guards in household appliances is safety protection: firstly, to cover the fan blades to prevent people from touching the high-speed rotating blades and causing accidents; and secondly, to prevent the high-speed rotating blades from falling off and injuring those nearby. Their functionality has not been further developed and utilized. Existing fan guards are not effective at reducing noise. Therefore, overcoming the aforementioned technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to overcome the defects described in the background art, thereby achieving a noise-reducing fan cover with good performance.

[0004] To achieve the above-mentioned objectives, the technical solution of this utility model is: a noise-reducing fan guard, comprising a guard body, the guard body comprising a guard base, the guard base having evenly distributed side lower support rods on its periphery, the other end of the side lower support rod being fixed by a lower support ring of the guard, and a side limiting ring being provided on the periphery of the lower support ring of the guard, the side limiting ring being slidably connected to an upper support ring of the guard, the upper part of the upper support ring of the guard having a side upper support rod and an arc-shaped upper support rod, the end of the arc-shaped upper support rod being connected by a central support plate.

[0005] Furthermore, the mesh cover base includes an outer support ring and an inner support ring, which are connected by circumferentially distributed base support rods. Noise reduction holes A are evenly arranged on the base support rods. The dense base support rods between the outer and inner support rings effectively disperse airflow and reduce turbulence. The noise reduction holes A can partially absorb noise.

[0006] Furthermore, buffer rods are evenly distributed around the circumference of the support ring under the mesh cover, and buffer springs are sleeved on the buffer rods. Limiting holes corresponding to the number and position of the buffer rods are provided on the support ring of the mesh cover. The buffer rods pass through the limiting holes, and limit blocks are connected to the ends of the buffer rods. When the fan vibrates during operation, the buffer springs can achieve a buffering effect between the upper and lower mesh covers, thereby reducing noise.

[0007] Furthermore, noise reduction holes B are evenly distributed on the inner sides of the arc-shaped upper support rod and the side upper support rod, and the noise reduction holes B can partially absorb noise.

[0008] Furthermore, noise reduction holes C are evenly distributed on the support plate, and the noise reduction holes C can partially absorb noise.

[0009] The beneficial effects of this noise-reducing fan guard are:

[0010] 1. The noise-reducing fan guard of this utility model has dense base support rods set between the outer support ring and the inner support ring of the base, which effectively disperses the airflow and reduces turbulence; when the fan vibrates during operation, the upper and lower guards can achieve a buffering effect under the action of the buffer spring, thereby reducing noise.

[0011] 2. The noise-reducing fan guard of this utility model has noise-reducing holes A evenly distributed on the base support rod, noise-reducing holes B evenly distributed on the inner side of the arc-shaped upper support rod and the side upper support rod, and noise-reducing holes C evenly distributed on the support plate, which realizes the absorption of noise and has a good effect.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] See Figures 1-4 The noise-reducing fan guard of this embodiment achieves good technical performance. The structure of this embodiment includes a guard body, which includes a guard base 11. The guard base 11 includes an outer support ring 111 and an inner support ring 113. The outer support ring 111 and the inner support ring 113 are connected by circumferentially distributed base support rods 112. Noise-reducing holes A1121 are evenly arranged on the base support rods 112. The dense arrangement of base support rods 112 between the outer support ring 111 and the inner support ring 113 effectively disperses airflow and reduces turbulence. The noise-reducing holes A1121 can partially absorb noise. The outer support ring 111 of the guard base 11 has evenly distributed side lower support rods 12. The other end of each side lower support rod 12 is fixed by a lower support ring 13, and a side limiting ring 2 is provided around the lower support ring 13.

[0020] See Figure 1 and Figure 3 In this embodiment, the side limiting ring 2 is slidably connected to the upper support ring 3 of the mesh cover. Buffer rods 6 are evenly distributed around the circumference of the lower support ring 13 of the mesh cover. A buffer spring 7 is sleeved on each buffer rod 6. Limiting holes 31 corresponding to the number and position of the buffer rods 6 are provided on the upper support ring 3 of the mesh cover. The buffer rods 6 pass through the limiting holes 31, and a limiting block 8 is connected to the end of each buffer rod 6. During fan operation, when overall vibration occurs, the buffer spring 7 can achieve a buffering effect between the upper and lower mesh covers, thus reducing noise. The upper support ring 3 of the mesh cover is provided with a side upper support rod and an arc-shaped upper support rod 42. The end of the arc-shaped upper support rod 42 is connected by a central support plate 5.

[0021] See Figure 3 and Figure 4 In this embodiment, noise reduction holes B421 are evenly distributed on the inner sides of the arc-shaped upper support rod 42 and the side upper support rod 41. The noise reduction holes B421 can partially absorb noise. Noise reduction holes C51 are evenly distributed on the support plate 5. The noise reduction holes C51 can partially absorb noise.

[0022] The operating principle and method of this embodiment are as follows: When the fan is working, the densely packed base support rods 112 between the outer support ring 111 and the inner support ring 113 of the base can effectively disperse the airflow and reduce turbulence. When the fan vibrates during operation, the buffer spring 7 can achieve the buffering effect of the upper and lower mesh covers. The noise reduction holes A1121 evenly arranged on the base support rods 112, the noise reduction holes B421 evenly distributed on the inner side of the arc-shaped upper support rod 42 and the side upper support rod 41, and the noise reduction holes C51 evenly distributed on the support plate 5 all absorb noise and achieve noise reduction.
