Description

Technical Field

[0001] The utility model relates to the technical field of filtering and exhausting air, in particular to a filtering and exhausting air box for a physical and chemical laboratory. Background Art

[0002] The filtration and exhaust system of the physical and chemical laboratory is one of the key facilities to ensure the clean, safe and efficient operation of the laboratory environment. During the physical and chemical experiments, various chemical reagents, gases and particulate matter are involved, so it is necessary to ensure that the air quality in the laboratory meets the standards to protect the health of the experimenters and ensure the accuracy of the experimental results. In summary, the filtration and exhaust system of the physical and chemical laboratory is an indispensable part of laboratory construction. It can not only protect the health of the experimenters and the accuracy of the experimental results, but also improve the work efficiency and safety of the laboratory. Therefore, in the process of laboratory construction and renovation, the design and configuration of the filtration and exhaust system should be fully considered to ensure that the overall operation of the laboratory is in the best state.

[0003] Patent publication number "CN220804895U" discloses "a chemical laboratory floor exhaust device", including a laboratory body, wherein an exhaust device is arranged inside the laboratory body, and the exhaust device includes an anti-blocking unit, an exhaust unit and a purification unit. The chemical laboratory floor exhaust device is provided with an anti-blocking unit. During the exhaust process of the laboratory body, the gas in the laboratory body is filtered out by the filter plate to remove large dust particles in the air, thereby preventing dust and impurities from accumulating in the exhaust pipe and causing blockage of the exhaust pipe. At the same time, the cleaning brush is driven by the moving plate to slide back and forth along the limit groove, thereby facilitating the cleaning of the filter plate, solving the problem proposed in the background technology that during the exhaust process, dust and impurities will enter the suction box and then enter the suction pipe. After long-term use, dust and impurities will accumulate in the suction pipe, causing blockage of the suction pipe, thereby affecting the normal operation of the exhaust device.

[0004] When the device in the above patent is used to remove dust and impurities accumulated in the intake pipe, if the dust and impurities are not collected promptly and effectively after cleaning, then during the process of the intake pipe sucking air, the fallen dust and impurities may be adsorbed onto the surface of the filter plate again, so that problems such as blockage cannot be solved. Therefore, it is necessary to improve the cleaning effect. Utility Model Content
