Abstract

The invention discloses a multi-air-flow-channel switching type ventilation cabinet for a laboratory, and particularly relates to the technical field of laboratory ventilation cabinets. The multi-air-flow-channel switching type ventilation cabinet comprises a ventilation cabinet body and a sliding door, an outer injection layer and an inner leading-out layer are sequentially arranged in the middleof the ventilation cabinet body from inside to outside, the outer injection layer and the inner leading-out layer are independent of each other and communicate with an air outlet and an air inlet respectively, the ventilation cabinet is provided with outer flow suction holes which communicate with the outer injection layer and the inner leading-out layer correspondingly, and the air outlet and the air inlet are formed in the ventilation cabinet correspondingly. According to the multi-air-flow-channel switching type ventilation cabinet, injection and leading-out are carried out at the same time to form different air flow channels, so that better ventilation and purification effects are achieved; and the pressure difference between air injection and air leading-out enables a partition plateto deform, so that the inner cavity space of the outer injection layer and the inner cavity space of the inner leading-out layer are adaptively adjusted, and air injection and air leading-out are combined to generate better ventilation and purification effects.

Description

technical field [0001] The invention relates to the technical field of laboratory fume hoods, and more specifically, the invention relates to a multi-air channel switchable fume hood for laboratories. Background technique [0002] The cabinet type exhaust hood is commonly known as a fume hood, which is similar to an airtight hood. Small parts painting cabinets and chemical laboratory fume hoods are typical structures of cabinet exhaust hoods. [0003] Common laboratory fume hoods are simple in structure and do not have multiple air flow channels, so it is difficult to adapt to the needs of ventilation work in different experimental environments, and the limitations are large, resulting in poor practicability. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a multi-air channel switching fume hood for laboratory use, including a fume hood and a sliding door. The middle part of the fume hood is provided with a...
