The evaporated water vapor is condensed to filter the water vapor in the gas sucked by the suction pump 403. A vent is provided at the side end of the condensation box 405. A heating pipe 406 is provided at the upper end of the vent. A filter screen 407 is fixedly installed at the other end of the heating pipe 406, and the filter screen 407 is fixedly installed at the lower end of the cabinet 1. Specifically, when the tableware is disinfected, the suction pump 403 and the heating pipe 406 are started, and the water vapor evaporated on the tableware is transferred to the condensation box 405 through the transfer pipe 404, and then the gas refluxed into the cabinet 1 is disinfected through the heating pipe 406.

[0026] The working principle of the present invention is as follows: when it is necessary to place tableware in the disinfection cabinet for disinfection, the tableware is placed above the limit block 205, the air pump is started, the air bag tube 215 and the air bag plate 214 fix the tableware above the limit block 205, the chopsticks are placed in the rolling cylinder 301, the drawer 102 is pushed, and after the drawer 102 is moved into the cabinet 1, the driving motor 303 and the purple light lamp and the incandescent lamp 402 are started, so that the placing cylinder 203 and the rolling cylinder 301 start to rotate and flip the tableware, so that the tableware is disinfected more completely; When the tableware is placed above the limit block 205, the airbag tube 215 and the airbag plate 214 fix and disinfect the tableware, and when the tableware needs to be placed together, the electronic telescopic rod 207 is started to shrink, so that the limit frame 208 pushes the resistance circle 212 to move, and the shrink rope 220 pulls the multiple limit blocks 205 closer to each other. When the tableware is collected together, the air pump and the winding motor 218 are reversely started to shrink the airbag tube 215 and the airbag plate 214 to make the tableware fit more closely. The limit spring 211 pushes the fixing ring 210 to push and squeeze the tableware, so that there is no gap between the tableware, so that the tableware can be collected together after disinfection, avoiding contact with the tableware that needs to be disinfected, resulting in secondary contamination of the disinfected tableware; When the ultraviolet lamp and the incandescent lamp 402 are used to sterilize the tableware, the suction pump 403 and the heating tube 406 are started, and the water vapor evaporated from the tableware is transferred to the condensation box 405 through the transfer tube 404, and then the gas flowing back into the cabinet 1 is sterilized through the heating tube 406.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
