Description

[0040] Embodiment 3 Reference Figures 1-11 For the third embodiment of the present application, an air purification device based on laboratory is provided.

[0041] When the staff uses the device, the air enters from one side of the adsorption mechanism 100, and then enters the next step through the adsorption plates 106. The first motor 103 can drive the sliding column 104 to rotate through the first output shaft 103a. The sliding column 104 is in sliding connection with the fixed shaft 105, and the first protrusion 104a drives the fixed shaft 105 to rotate. The fixed shaft 105 is in fixed connection with the plurality of adsorption plates 106, so that the adsorption plates 106 rotate stably in the annular groove 102a. When the adsorption plates 106 need to be replaced, the first housing 101 is removed, and then the disc 104c is pulled, so that the second protrusion 104b is separated from the limiting groove 103a1. At this time, the fixed shaft 105 and the plurality of adsorption plates 106 can be taken out. When installation is needed, the disc 104c is kept pulled, and the disc 104c is placed in the annular groove 102a. The disc 104c is removed, and the second protrusion 104b reenters the limiting groove 103a1.

The third motor 203a is started, so that the second output shaft 203b rotates. The pump 203d sucks the absorption liquid in the absorption pool 202 through the liquid inlet pipe 203e, so that the absorption liquid enters the liquid storage cavity 203c2 in the liquid inlet box 203c. Continue to flow into the liquid inlet 203b2 to the communication cavity 203b1, so as to provide the absorption liquid for the plurality of hoses 203f1. Due to the rotation of the second output shaft 203b, the centrifugal force generated gradually stretches the second spring 203f4 in the shell 203f3, so as to gradually open, so as to provide better absorption liquid and air and filter cotton net 201a to contact, and due to the special angle of the shell, while rotating, the driving force of the air is generated, so as to accelerate the flow of air when more air needs to be purified, and increase the purification degree of the air.

[0043] The treated air is used according to the required use of the deodorizing brush, sterilization and the like.
