Safety fume hood easy to clean

Abstract

The invention discloses a safety fume hood easy to clean. The safety fume hood comprises a fume hood body and an exhaust fan disposed outside the fume hood body, the fume hood body comprises a lower cabinet body and an upper cabinet body disposed above the lower cabinet body, an experiment table is arranged at the bottom of the upper cabinet body, a sliding window and a display controller are arranged on a front panel of the upper cabinet body, the sliding window is provided with a window driving device and a human body displacement sensor, and the human body displacement sensor is disposed atthe upper position of the sliding window. An exhaust hood and an exhaust pipeline are arranged in the top of the upper cabinet body, one end of the exhaust pipeline communicates with the top of the exhaust hood, the other end of the exhaust pipeline is connected to the exhaust fan, and the window driving device and the human body displacement sensor are electrically connected with a display controller. The safety fume hood has the beneficial effects that the exhaust hood is arranged, when dust accumulation or corrosion occurs, only the exhaust hood needs to be removed, the cleaning and replacement are convenient, the sliding window can realize automatic opening and closing, and environmental protection and safety are achieved.

Description

technical field [0001] The invention relates to the field of experimental instruments, in particular to an easy-to-clean safe fume hood. Background technique [0002] Chemical substances and organisms, as well as particles (smoke, soot, dust and aerosols), are easily produced during chemical experiments. If these substances cannot be removed from the laboratory as soon as possible, it will have an impact on the body of the experiment operator. Therefore, the existing fume hoods are all equipped with exhaust devices to quickly discharge the exhaust gas, but there are some disadvantages: (1) The exhaust gas will directly contact the inner wall of the fume hood during the exhaust process, and some of the dust will remain in the ventilation cabinet. The inner wall of the fume hood, another part of the chemical gas and the long-term contact with the fume hood will cause corrosion of the fume hood. The existing fume hood is very laborious to clean the inner wall. Once corrosion oc...

[0002] Chemical substances and organisms, as well as particles (smoke, soot, dust and aerosols), are easily produced during chemical experiments. If these substances cannot be removed from the laboratory as soon as possible, it will have an impact on the body of the experiment operator. Therefore, the existing fume hoods are all equipped with exhaust devices to quickly discharge the exhaust gas, but there are some disadvantages: (1) The exhaust gas will directly contact the inner wall of the fume hood during the exhaust process, and some of the dust will remain in the ventilation cabinet. The inner wall of the fume hood, another part of the chemical gas and the long-term contact with the fume hood will cause corrosion of the fume hood. The existing fume hood is very laborious to clean the inner wall. Once corrosion occurs, the inner wall of the fume hood must be replaced as a whole; (2) Large The sliding windows of some fume hoods use manual switches, but when the experimenters are busy, they often need to put down the experimental equipment before opening the fume hood, which is inconvenient and unsafe to operate
