[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4The medicine cabinet ventilation device comprises a medicine cabinet body 2, in which a plurality of groups of placement boxes 3 are inserted at equal intervals in a circle, a slot is provided on the medicine cabinet body 2, a ventilation pipe 7 is provided in the slot, the ventilation pipe 7 is connected with the placement box 3 through a branch air pipe 701, a fan 5 is provided at the air inlet end of the ventilation pipe 7, a purification box 6 is provided at one end of the placement box 3 away from the branch air pipe 701, the purification box 6 is connected with the placement box 3 through a first air pipe, an activated carbon plate 602 is provided above the first air pipe in the purification box 6, and a one-way valve 702 is provided in the branch air pipe 701.

[0022] When medicines are stored in the placement box 3, the fan 5 works and rotates slowly to introduce gas into the ventilation pipe 7. When the gas passes through the gas distribution pipe 701, the one-way valve 702 opens and the gas enters the placement box 3. At this time, the gas in the placement box 3 enters the purification box 6 with the flow of gas, is adsorbed and purified by the activated carbon plate 602, and then rises and is discharged through the air outlet of the purification box 6, thereby realizing ventilation of the placement box 3 and purifying the exhaust gas. Compared with the existing medicine cabinet, the gas in the placement box 3 is replaced and the exhaust gas is purified by the fan 5, the ventilation pipe 7 and the purification box 6, which effectively ensures the health of the experimenters and the protection of the environment.
