The tool box 14 can be equipped with tools related to the temporary storage equipment for maintenance.

[0037] Working principle of this embodiment: When in use, the operator holds the handle 207 and slides the outer drawer 201 out of the cabinet 1. Then, the operator can place the same type of hazardous waste in the rubber box 303 of the inner drawer assembly 3, and the rubber frame 305 separates the waste. At this time, if the waste is solid or liquid waste, the solid waste will still remain in the rubber box 303, and the liquid will flow downward through the liquid hole 304 and pass through the supporting mesh plate 203 to gather on the bottom inner wall of the outer drawer 201. Then, the operator pushes the outer drawer assembly 2 into the cabinet 1. At this time, the ultraviolet sterilization lamp 4 can sterilize the waste in the rubber box 303. In this way, the temporary storage and use of the temporary storage equipment for laboratory hazardous waste is completed;

[0038] When the waste is to be taken out, the operator can first remove the sealing cover 206, and the liquid waste in the outer drawer 201 will be discharged through the connecting pipe 205, and the operator can collect it. Then, the operator slides out the outer drawer assembly 2, and then slides out the inner drawer assembly 3, and the solid waste can be directly taken out as a whole, and the operator collects it. In this way, the operation of taking out the waste in the temporary storage device is completed;
