[0035] Preferably, the lower surface of the partition 11 is provided with a blind hole extending upwards. An automatic vent valve 18 is sealed and installed in the lower section of the blind hole relatively close to the orifice (the automatic vent valve uses the buoyancy of the valve core itself to achieve gas flow and liquid barrier; when there is gas in the vent pipe, the valve core will rise and open the vent, allowing the gas to be discharged. When the gas is discharged, the valve core will descend due to gravity and close the vent, thereby preventing liquid from entering). The upper section of the blind hole relatively close to the bottom of the hole is an empty area; an vent channel 19 extending through the empty area of ​​the blind hole is provided on the outer surface of the upper housing 1.

[0036] Preferably, the upper shell 1 is in the shape of a quadrangular prism, and symmetrically arranged grippers 17 are provided on every two opposite side walls of the upper shell 1.

[0037] Preferably, the lower end of the lower housing 2 is fitted with a non-woven fabric cover 6, which is in contact with the outer surface of the outer bottom wall 23 of the lower housing 2.

[0038] Preferably, the volume of the liquid storage chamber A12 in the upper shell 1 is 3-10 times the volume of the liquid storage chamber B13.

[0039] Preferably, the lower end of the abutment plate A421 is provided with a positioning protrusion A4212, and correspondingly, the partition plate 11 is provided with positioning recesses A and B that match the positioning protrusion A4212. When the positioning protrusion A4212 on the abutment plate A421 is inserted into the positioning recess A, the through hole A4211 on the abutment plate A421 is aligned with the connecting hole 14 on the partition plate 11. When the positioning protrusion A4212 on the abutment plate A421 is inserted into the positioning recess B, the through hole A4211 on the abutment plate A421 is misaligned with the connecting hole 14 on the partition plate 11.

[0040] Preferably, the lower end of the abutment plate B521 is provided with a positioning protrusion B5212. Correspondingly, the bottom surface of the liquid storage cavity B13 of the upper housing 1 is provided with positioning recesses C and D that match the positioning protrusion B5212. When the positioning protrusion B5212 on the abutment plate B521 is embedded in the positioning recess C, the through hole B5211 on the abutment plate B521 is directly opposite to the liquid outlet hole 16 at the bottom of the upper housing 1. When the positioning protrusion B5212 on the abutment plate B521 is embedded in the positioning recess D, the through hole B5211 on the abutment plate B521 is offset from the liquid outlet hole 16 at the bottom of the upper housing 1.

[0041] Briefly describe the use of this utility model:

[0042] Sufficient alcohol for multiple sterilizations is added to the storage chamber A12 of the upper housing 1 through the replenishment port 15. The lever A42 is slightly pulled and rotated so that the positioning protrusion A4212 on the abutment plate A421 is engaged with the positioning recess A (at this time, the through hole A4211 on the abutment plate A421 is aligned with the connecting hole 14 on the partition plate 11), opening the connecting hole 14. A portion of the alcohol in the storage chamber A12 then enters the storage chamber B13 through the connecting hole 14, while the air in the storage chamber B13 is discharged to the outside through the automatic exhaust valve 18 and the exhaust channel 1.

[0043] When the reservoir B13 is full, it contains the amount of alcohol needed for one disinfection. After the reservoir B13 is full, slightly lift and rotate the lever A42 so that the positioning protrusion A4212 on the abutment plate A421 is inserted into the positioning recess B (at this time, the through hole A4211 on the abutment plate A421 is misaligned with the connecting hole 14 on the partition plate 11), thus sealing the connecting hole 14. After sealing the connecting hole 14, slightly lift and rotate the lever B52 so that the positioning protrusion B5212 on the abutment plate B521 is inserted into the positioning recess C (at this time, the through hole B5211 on the abutment plate B521 is aligned with the liquid outlet hole 16 at the bottom of the upper housing 1), thus opening the liquid outlet hole 16.

[0044] The alcohol in the reservoir B13 then enters through the tubing 3 and fills the interlayer 22 of the lower housing 2, and then permeates the non-woven fabric cover 6 through the capillary pores 26. The operator holds the gripper 17 to rub and push the non-woven fabric cover 6 on the surface of the CT examination bed 11, thereby disinfecting the CT examination bed 100.
