When the placement rack body (301) is continuously pressed, the two racks (401) fixedly connected thereto will also move downwards. When the racks (401) move downwards, the surfaces of the racks (401) will mesh with the first gear (402). When the racks (401) move downwards, the first gear (402) will continuously rotate. When the first gear (402) continuously rotates, it will drive the first rotating shaft (406) to rotate. At the same time, when the racks (401) move downwards, it will continuously press the first spring (404). When the first rotating shaft (406) is fixedly connected thereto, it will rotate. The second gear (407) connected thereto will also rotate continuously. When the second gear (407) rotates, the third gear (408) meshing therewith will also rotate continuously. When the third gear (408) rotates, the second rotating shaft (410) in the middle thereof will also rotate. When the second rotating shaft (410) rotates, it will drive the reciprocating screw (504) to rotate. The reciprocating screw (504) will drive the moving block (503) above it to move. When the moving block (503) moves to the right on the top of the second box body (502), the disinfectant water in the first box body (501) will enter the second box body (502) through the electronic valve on the second box body (502). When the moving block (503) moves to the right on the top of the second box body (502), the disinfectant water in the first box body (501) will enter the second box body (502) through the electronic valve on the second box body (502).

The delivery mechanism (5) realizes the reciprocating motion of the reciprocating screw (504) in the second box (502) through the influence of the transmission mechanism (4). When the disinfectant water is transported to the third box (601), the disinfectant water in the third box (601) continues to increase and the disinfectant water in it will squeeze the energy storage plate (609). The energy storage plate (609) will move downward when it is squeezed by pressure. When the disinfectant water in the third box (601) reaches a certain amount, the first rotating shaft (406) When the rotation stops, disinfectant water will no longer be transported into the third box (601), and the box cover (2) on the instrument box (1) is closed. At this time, the electronic valve on the output end of the third box (601) is opened, and the disinfectant water in the third box (601) is transported to the inside of the second delivery pipe (602) through the output end of the third box (601). At the same time, the second spring (606) squeezed by the energy storage plate (609) will continue to contract to accelerate the disinfectant water in the third box (601) to go out of the third box (601). When the box cover (2) of the instrument box (1) is opened, the first spring (404) moves upward to reset the placement rack body (301).
