In addition, the filter is inconvenient to replace and clean, resulting in untimely filter maintenance and reduced filtering effect. At the same time, there is a lack of effective sterilization mechanism, and the safety of the air cannot be ensured.

[0032] The present invention also discloses a control method for intelligent laboratory air quality control equipment, comprising the following steps: Step 1, the ventilation fan blades 604 are set to work through the driving component, which is used for the ventilation duct to work, and then the filter bracket 302 connected by the snap-fit ​​component is used to block the dust. Specifically, the set first support shaft 601 is driven by the motor, and the movable shaft 603 is rotated on the support shell 6 through the first bevel gear set 602, driving the rotation of the ventilation fan blades 604, and sending fresh air from the outside into the laboratory to optimize the experimental environment, thereby ensuring that the air in the laboratory is always fresh. A filter bracket 302 is set at the input port of the ventilation duct 2 to filter dust from the ventilated air, thereby improving the cleanliness of the internal environment of the laboratory, and the set filter bracket 302 slides along the slide groove 303 through the protrusion on the outer wall, and the filter bracket 302 is connected to the filter duct 2 to block the dust from the ventilated air. The pull rod 403 compresses the block 402 along the spring 401 on the L-shaped bracket 4.
