Description

Technical Field

[0001] The utility model belongs to the technical field of basement ventilation, and particularly relates to a basement ventilation filtering device. Background Art

[0002] The basement ventilation and filtration device is a device specially designed for improving the air quality in the basement. It is mainly composed of important parts such as air inlets, filters, fans and air ducts. The air inlet is usually set outside the basement and undertakes the key responsibility of introducing fresh air from the outside. There are various types of filters, including primary, medium and high efficiency filters, which can effectively filter dust, pollen, bacteria, viruses and other types of pollutants in the air. The fan plays a vital role by continuously operating to draw in fresh air from the outside and push the dirty air out of the basement. The role of the air duct is to guide the air to achieve reasonable flow and ensure that the purified fresh air can be evenly distributed to every corner of the basement. In short, the basement ventilation and filtration device relies on the coordinated cooperation of various components to successfully purify and renew the basement air, creating a healthier and more comfortable environment for users.

[0003] The Chinese patent with the announcement number "CN214665018U" discloses a basement ventilation and filtering device for civil air defense, in which an air inlet is provided at the left end of the box body, an air outlet is provided at the right end, a fan is installed in the middle of the box body, and a plurality of groups of positioning grooves are equidistantly arranged inside the box body, a card block is provided in the positioning groove, the upper end of the card block is connected to the filter screen, and a frame is provided on the side of the filter screen. The advantage of the utility model is that the filter screen can be conveniently connected and disassembled with the box body, which is convenient for cleaning the filter screen separately. Through a plurality of groups of equidistantly arranged filter screens, the filtering and purification effect is more outstanding, and it is convenient to perform the operation of separating the filter screen from the box body. The separation operation of the connecting block and the filter screen is simple and easy to operate. By pushing the positioning block to tilt and move in the card slot, the two groups of magnets that attract each other are separated, and then the connecting plate is separated, and the arc groove is also separated from the connecting rod, so that one end of the positioning block is moved out of the connecting slot. The whole process saves time and effort, and is suitable for wide promotion.

[0004] In actual application, the above-mentioned device filters dust in the external air through the filter. However, in a specific application scenario, after the filter filters out the dust, the dust will inevitably adhere to the outer surface of the filter. The dust adhering to the outer surface of the filter will obviously cause the filter to be blocked. If it is not cleaned for a long time, as the dust continues to accumulate, the air circulation efficiency inside the ventilation duct will inevitably be reduced. It can be seen that the existing equipment has certain defects and deficiencies during use, so it needs to be improved and optimized. Utility Model Content

[0031] Principle and advantages of use: By setting the card installation mechanism 6, during the use of the device, the sliding block 75 is slidably set inside the guide rail 74, and then the slide plate 5 is inserted into the inside of the slide groove 4 to ensure that the limit column 72 is inserted into the limit hole 12. After the installation is completed, the limit spring 63 is reset to drive the slider 64 to slide on the inner side of the bottom rail 61. The sliding of the slider 64 can drive the card block 65 to be inserted into the inside of the limit frame 62. The card block 65 and the limit frame 62 are mutually engaged and limited, so that the sealing plate 73 can be carded and installed at the bottom of the ventilation pipe 1, and then equipped. The limiting column 72 and the limiting hole 12 are limited, and the top rail 761 can be limitedly installed. If it needs to be disassembled, just pull the drawer armrest 66, and the slider 64 can be pulled to resist the limiting spring 63 to contract and make the block 65 separate from the limiting frame 62. The block 65 and the limiting frame 62 are separated from each other, and the sealing plate 73 can be quickly disassembled and assembled. The limiting hole 12 and the limiting column 72 are separated from each other, and the sliding block 75 inside the guide rail 74 can be pulled out, so that the whole device can be quickly repaired, maintained and cleaned, which can improve the convenience of the overall repair and disassembly of the filter screen 71 of the device;

[0032] By setting the cleaning component 76, the device can assist in filtering dust entrained during air circulation through the filter screen 71 during use. The dust is filtered out and adheres to the filter screen 71. When the filter screen 71 needs to be cleaned, the drive motor 763 can be started to operate, and the drive motor 763 can be used to drive the gear 764 to rotate. The rack 765 is fixedly connected to one side of the top rail 761, and the gear 764 and the rack 765 are meshed. As the gear 764 and the rack 765 are meshed, the slide seat 762 can be driven to slide up and down on the inner side of the top rail 761 by the rotation of the drive gear 764. The slide seat 762 can be driven to slide up and down. The support plate 766 can be moved up and down, and the support plate 766 can drive the brush plate 767 to move up and down. The brush plate 767 can be attached to the outer surface of the filter 71 to brush and clean it, and the filter 71 located inside the ventilation pipe 1 can be automatically brushed and cleaned, which can improve the overall cleaning efficiency of the device. The device does not need to be disassembled for cleaning. The automatic cleaning design can prevent dust from clogging the filter 71 and affecting ventilation. At the same time, the design of a bridge-type handrail 769 on the fixed plate 8 is adopted. The slide plate 5 can be pulled out and pulled to slide on the inner side of the slide groove 4, so that the filter 71 can be quickly pulled out and disassembled, which can improve the convenience of the overall disassembly, maintenance and overhaul of the device.
