This not only further improves the disinfection effect and efficiency, reduces the use cost, but also can avoid the problem that the high-temperature steam condenses into water and causes the objects to be re-contaminated after disinfection, ensuring the dryness of the internal environment of the inner container 2 and the dryness of the surface of the objects, with strong practicability.

[0028] The pipelines include a water inlet pipe 7, a water outlet pipe 8, and a steam output pipe 9. The fluid controller 4 is a water pump or a solenoid valve, its water inlet end is interconnected with the water tank 3 through the water inlet pipe 7, the water outlet end of the fluid controller 4 is interconnected with the evaporator 5 through the water outlet pipe 8, and the evaporator 5 is interconnected with the inner container 2 through the steam output pipe 9.

[0029] The water in the water tank 3 sequentially enters the evaporator 5 through the water inlet pipe 7, the fluid controller 4, and the water outlet pipe 8, and the high-temperature steam generated by the evaporator 5 is transported into the inner container 2 through the steam output pipe 9.

[0035] The water pumping volume of the fluid controller 4 is controlled by the electric control device 22 so that the evaporator 5 can generate an appropriate amount of high-temperature steam.

[0036] The fluid controller 4 pumps the water in the water tank 3 into the evaporator 5 through the control of the electric control device 22.

The outer frame 23 is respectively fixed to the inner wall of the outer shell 1 and the periphery of the inner tank 2. A fixing plate 24 is provided on the outer shell 1, the inner tank 2 or the outer frame 23. The fixing plate 24 is located at the top, back, side or bottom of the inner tank 2. The fluid controller 4, the evaporator 5 and the electric control device 22 are respectively fixedly arranged on the fixing plate 24.

[0043] A bracket 25 is provided on the outer shell 1, the inner tank 2 or the outer frame 23. The water tank 3 is detachably mounted on the bracket 25, or the water tank 3 is fixedly arranged on the bracket 25 and is provided with a water supply pipe communicated with the water supply end thereon.

[0044] The water tank 3 replenishes water by means of detachable water addition or direct water addition communicated with the water supply end, which is convenient for users to use.

[0045] In this embodiment, the fixing plate 24 is located at the top of the inner tank 2 and is fixedly connected to the outer frame 23. The fluid controller 4, the evaporator 5 and the electric control device 22 are all fixedly arranged on the fixing plate 24. The bracket 25 is located in front of the fixing plate 24 and is fixedly arranged at the top of the inner tank 2.

[0047] Specifically, a front frame 26 is provided on the front side of the outer frame 23. A fixed panel 27 is provided on the front frame 26, and a fixed panel disassembly and assembly opening is provided on the fixed panel 27. The bracket 25 is located at the rear side of the fixed panel disassembly and assembly opening. The water tank 3 is disassembled and assembled on the bracket 25 through the fixed panel disassembly and assembly opening. Thus, the user can directly disassemble and assemble the water tank 3 at the fixed panel disassembly and assembly opening, which is convenient to use.

[0048] In this embodiment, a chute is provided on the bracket 25.

In addition, a limiting member 30 is also provided on the bracket 25, and the water tank 3 is limited by the limiting member 30 during assembly.

[0049] During use, the fluid controller 4 extracts a certain amount of water from the water tank 3 and transports it to the evaporator 5 under the control of the electric control device 22. Subsequently, the electric control device 22 controls the evaporator 5 to work. When the evaporator 5 is working, it heats the water flowing inside, causing it to boil and form high-temperature steam. The high-temperature steam then enters the inner tank 2. When the inner tank 2 is filled with high-temperature steam, the fluid controller 4 and the evaporator 5 stop working, and the heating tube 6 starts to work. Or, while the high-temperature steam enters the inner tank 2, the heating tube 6 works simultaneously, so that the heating tube 6 not only heats and disinfects the objects in the inner tank 2, but also reheats the high-temperature steam to make the high-temperature steam reach a higher temperature, thereby comprehensively disinfecting the objects in the inner tank 2 in a short time and at the same time realizing the rapid drying of the high-temperature steam.
