Description

Technical Field

[0001] The utility model relates to the technical field of fume hoods, in particular to a fume hood convenient for maintenance. Background Technique

[0002] The cabinet-type exhaust hood is commonly known as a fume hood. Similar to the closed hood, the small part spray painting cabinet and the chemical laboratory fume hood are typical structures of the cabinet-type exhaust hood. For the large chamber fume hood, one side is completely open, and the operator works inside the cabinet, which is mainly used for large-piece spray painting, powder bagging, etc. The working opening of the fume hood has a great influence on the air flow distribution inside the cabinet, and the air flow distribution directly affects the working effect of the cabinet-type exhaust hood.

[0003] For example, the Chinese authorized patent (fume hood device) with the publication number of CN214053042U: includes a fume hood body, a gas circulation component, a first exhaust duct body, a second exhaust duct body and an air volume regulating valve. An air drying table is arranged on the fume hood body, an air inlet cavity is arranged inside the fume hood body, a ventilation hole communicated with the air inlet cavity is arranged on the air drying table, and an air inlet communicated with the air inlet cavity is also arranged on the fume hood body. The gas circulation component is arranged inside the air inlet cavity. The air outlet of the gas circulation component is communicated with the first exhaust duct body and the second exhaust duct body. The first exhaust duct body extends to the air drying table, and the second exhaust duct body extends to the outside of the fume hood body. Air volume regulating valves are arranged on both the first exhaust duct body and the second exhaust duct body. This fume hood device can meet the requirements of wind speed and air volume during product air drying and meet the external exhaust air volume demand. When this fume hood device is in use, the air volume and wind speed on the first exhaust duct body and the second exhaust duct body can be adjusted through the air volume regulating valve.

[0004] However, most of the bases of the existing fume hoods are opened in one direction for maintenance. When maintaining the components behind the base, personnel need to crawl in, which is time-consuming and laborious. Moreover, the maintenance door is easily touched and its angle is changed, affecting personnel maintenance and causing harm to the skin of personnel. Therefore, it does not meet the existing requirements, and for this reason, we propose a fume hood convenient for maintenance. Content of the Utility Model
