Description

Technical Field

[0001] The present invention relates to the technical field of dust separation, and particularly to an air filtration device for a dust-proof CPU radiator. Background Art

[0002] The air filtration device for a dust-proof CPU radiator generally consists of parts such as a filter screen, a frame, a fan, and a disassembly device assembly.

[0003] The patent with the patent announcement number CN210434177U relates to an air filtration device for a dust-proof CPU radiator, which includes a radiator fan and a filter device main body. The radiator fan includes a housing with a through hole provided in the center and a fan provided in the through hole of the housing. The filter device main body includes a fixing plate and a filter. The fixing plate is detachably connected to the top of the housing. The central hole of the fixing plate is concentric with the through hole of the housing and has the same size and shape. The filter includes a top plate, a star-shaped plate, and a bottom plate. The top plate, the star-shaped plate, and the bottom plate are all of a three-layer structure, which are the upper layer, the middle layer, and the lower layer in sequence. The upper layer and the lower layer are filter mesh layers, and the middle layer is an adsorption layer. The bottom of the top plate is hermetically connected to the top of the star-shaped plate, and the top of the bottom plate is hermetically connected to the bottom of the star-shaped plate and hermetically connected to the fixing plate at the bottom. The purpose is to solve the problem that when the CPU radiator works for a long time, the dust entering the chassis will gradually cover the radiator fan and the heat sink, affecting the heat dissipation function of the CPU radiator.

[0004] In the above patent, by hermetically connecting the top of the bottom plate to the bottom of the star-shaped plate and hermetically connecting it to the fixing plate at the bottom, the purpose is to solve the problem that when the CPU radiator works for a long time, the dust entering the chassis will gradually cover the radiator fan and the heat sink, affecting the heat dissipation function of the CPU radiator. However, it is difficult to prevent the reduction of the filtering effect caused by the loosening of the filter plate. The loosened filter plate is difficult to effectively play the role of filtering dust, which in turn causes substances such as dust and fine particles to enter the interior of the radiator, thereby exacerbating the increase in the radiator temperature and affecting the heat dissipation efficiency.

[0015] The present invention provides a dust-proof air filtering device for a CPU radiator. It has the following beneficial effects:

[0016] (1) For this dust-proof air filtering device for a CPU radiator, by manually pushing the free end of the elastic telescopic rod to move to the right first, the limit on the T-shaped rod can be released. The elastic telescopic rod ensures that the filter plate remains stable and is not loosened by external force extrusion, and can more effectively filter tiny particles such as dust and impurities in the air, thereby ensuring the filtering effect of air filtration. By moving the mounting rod to the left, the filter plate is ejected, and the detachable filter plate can prevent excessive dust accumulation and ensure smooth air flow, thereby further improving the filtering effect of air filtration.

[0017] (2) For this dust-proof air filtering device for a CPU radiator, through the arc-shaped block, the mounting plate moves slowly, driving the mounting rod to move slowly. The slow movement of the mounting rod ejects the filter plate slowly. By the slow movement of the filter plate, excessive force acting on the filter plate can be avoided, thereby preventing the filter plate from deforming, and further ensuring better sealing performance between it and the filter frame, thereby assisting in improving the filtering effect and reducing the entry of dust.

[0018] (3) For this dust-proof CPU radiator air filtration device, the dust adsorbed on the left side of the adsorption plate is scraped off by the curved rod, thereby improving the adsorption effect of the adsorption plate. The mechanism of scraping dust by the curved rod can maintain the secondary dust-proof ability of the adsorption plate. By vibrating the curved rod to loosen the dust at the dead angle between the curved rod and the adsorption plate, the adsorption effect of the adsorption plate can be further improved, thus enhancing the overall filtration effect and ensuring that no dead angle is overlooked.

[0019] (4) For this dust-proof CPU radiator air filtration device, the antistatic agent inside the protective frame enters the bottom of the hollow frame through the liquid inlet hole. By spraying a quantitative amount of antistatic agent, the large accumulation of dust due to static electricity on the left side of the adsorption plate can be reduced, thereby assisting in improving the effect of the adsorption plate in secondarily filtering dust and helping the radiator maintain the best heat dissipation effect.

[0020] (5) For this dust-proof CPU radiator air filtration device, the inside of the guide tube is dredged by the reciprocating movement of the moving ring to prevent dust from accumulating inside the guide tube. Through the continuous dredging of the moving ring, it is ensured that there is no dust accumulation in the guide tube, avoiding the situation of uneven spraying, thereby improving the usage efficiency of the antistatic agent.

By means of the elastic telescopic rod 13, it is ensured that the filter plate 5 remains stable and is not loosened by external force extrusion, so that dust, impurities and other fine particles in the air can be filtered more effectively, and thus the filtering effect of air filtration is ensured.

A first spring is provided between the mounting plate 9 and the mounting frame 7. The first spring can drive the mounting plate 9 to reset. By slowly moving the filter plate 5, excessive force acting on the filter plate 5 can be avoided, so as to prevent the filter plate 5 from deforming, and thus ensure better sealing between it and the filter frame 1, thereby assisting in improving the filtering effect and reducing the entry of dust.

The guide pipe 165 penetrates the bottom of the protective frame 161, and the guide pipe 165 penetrates the inner and outer walls of the filter frame 1. The reciprocating movement of the moving ring 167 dredges the inside of the guide pipe 165 to prevent dust from accumulating inside the guide pipe 165.

The dust adsorbed on the left side of the adsorption plate 157 is scraped off by the curved rod 154, thereby improving the adsorption effect of the adsorption plate 157. At the same time, the curved rod 154 rotates to contact the arc panel 155 and hit the arc panel 155. The arc panel 155 vibrates due to the impact of the curved rod 154.

The vibration of the curved rod 154 loosens the dust in the dead corner between the curved rod 154 and the adsorption plate 157, further improving the adsorption effect of the adsorption plate 157.

[0041] The curved rod 154 rotates to contact the inclined surface of the connecting plate 163 and squeeze the connecting plate 163. The connecting plate 163 is squeezed upward by the curved rod 154. The connecting plate 163 moves upward to contact the liquid inlet hole 164 and releases the seal on the bottom of the hollow frame 162. After the seal on the bottom of the hollow frame 162 is released, the antistatic agent inside the protective frame 161 enters the bottom of the hollow frame 162 through the liquid inlet hole 164.
