Excellent laboratories often represent the highest level of cutting-edge basic research in the world, and are very likely to produce Nobel Prize winners and epoch-making scientific and technological innovations. They are important places for high-level academic exchanges. Ventilation is a technology that uses natural or mechanical methods to allow wind to pass through without obstruction and reach a room or a sealed environment to create a hygienic, safe and suitable air environment. Frequent ventilation can improve indoor air quality and is good for health.

[0020] The working principle of the above technical solution is as follows: when in use, the user moves the equipment to a suitable working position through the universal wheel 9, and then starts the equipment with an external power supply. At this time, the fan 22 rotates to draw out the airflow inside the box 1, forming a negative pressure inside the box 1. At this time, the airflow enters the installation box 13 through the through hole 12, and first filters out large particles of impurities such as flying catkins and dust through the primary sponge filter plate 11, and then the airflow enters the central filter cartridge 18 through the through hole three 23.

[0021] In another embodiment, Figure 3 As shown, four elastic telescopic columns 21 are evenly distributed in a circle inside the box body 1 .
[0022] The setting of the elastic telescopic column 21 can make the plastic sealing plate 20 fit with the top of the central filter cartridge 18, stabilize the torque of the central filter cartridge 18 and seal the top of the central filter cartridge 18, so that the airflow is guided to the outside through the center of the central filter cartridge 18, which is easy to use and stable to install to avoid shaking.

[0028] When the airflow is filtered, it first passes through the center inside the central filter cartridge 18, first filters the smaller particles through the secondary sponge filter cartridge 1801, then passes through the activated carbon adsorption cartridge 1802 to adsorb and filter the odor molecules and some harmful gases and particles, and finally passes through the PM2.5 filter paper cartridge 1803 to filter extremely small particles and objects such as suspended viruses. Multi-stage filtration facilitates the cleanliness of the airflow.
