At present, in public places, offices, home environments and outdoor areas, there are large amounts of toxic and harmful gases and smoke everywhere, leaving unpleasant odors on clothes. The existing disinfection storage cabinets cannot truly achieve the disinfection effect because they cannot discharge the air inside the cabinets. Some storage cabinets currently available have ventilation functions, but they merely simply expel the gases outside the cabinets. These gases cause indoor air pollution and cause varying degrees of damage to home walls, furniture, household appliances, etc., thereby affecting the healthy indoor environment of people. Currently, there is no such ventilation-disinfection storage cabinet available in the market.

Disinfect the items in the storage cabinets, carry out automatic ventilation, and provide people with a healthy and hygienic indoor environment. 
The technical solution adopted by this air-changing disinfection storage cabinet to solve its technical problems is as follows: A storage cabinet with air-changing function is designed based on the principles of electrical engineering and mechanical engineering. It consists of the cabinet body, cabinet door, textured filter trough, disinfection device, wooden partition, mesh filter holes, electric vacuum pump, and microcomputer MCU control switch. The cabinet body of a storage cabinet with air-changing function is a common storage cabinet body, in the shape of a cuboid. The cabinet door is of the common left-opening or right-opening or double-opening type and is installed at the front of the cabinet body of the storage cabinet. The disinfection device adopts a common ozone sterilization device and ultraviolet lamp tube sterilization device, and is installed in the cabinet body. The electric vacuum pump is an existing centrifugal vacuum fan with an electric motor, fixedly installed at the bottom of the inner cavity of the cabinet body. The microcomputer MCU control switch is a common microcomputer control switch, which is used for timing control of the disinfection and air-changing switches and is installed on the top of the storage cabinet for easy operation. A storage cabinet with air-changing function is designed with a textured filter trough on the top, allowing fresh air to pass through smoothly while blocking dust. 
This air-permeable disinfection storage cabinet has its interior cavity divided into storage space and an electric vacuum pump space by wooden partitions. The wooden partitions are in the shape of a cuboid and are fixed inside the disinfection storage cabinet. They are designed with mesh-like filtering holes to prevent objects from falling from the storage space. Due to the diagonal arrangement of the textured filtering trough and the mesh-like filtering holes, there is no dead corner in the disinfection storage cabinet interior. An air-permeable disinfection storage cabinet consists of the cabinet body, cabinet door, textured filtering trough, disinfection device, wooden partitions, mesh-like filtering holes, electric vacuum pump, and microcomputer MCU control switch. When the full disinfection and ventilation function is activated, the timer control disinfection and ventilation switch on the microcomputer MCU switch of this utility model is turned on. The disinfection device is activated, and the ozone sterilization device and ultraviolet lamp tube sterilization device start to work normally. After 10-20 minutes, the disinfection device stops working, and the ventilation program automatically starts. The motor works, and the fan rotates. The contaminated gas in the disinfection storage cabinet passes through the mesh-like filtering holes and is extracted outdoors through the PVC ventilation pipe. The fresh air in the room then enters the disinfection storage cabinet through the textured filtering trough for circulation. Main uses: It has the basic storage function of a regular storage cabinet, such as a changing and shoe storage cabinet.
