The partition plate 2 is arranged substantially horizontally in the middle of the sterilization chamber 121 and divides the sterilization chamber 121 into a first chamber 1211 located above and a second chamber 1212 located below. The rear end of the partition plate 2 is provided with a first mounting opening 21, the partition plate 2 is hollow and is internally provided with a heating pipe 22, and the first chamber 1211 and the second chamber 1212 can be dried at the same time, so that the part cost is saved. In this embodiment, the heating pipe 22 is disposed inside the partition plate 2 in a serpentine shape, and serves as a planar heating source, and the partition plate 2 is made of a heat conductive material.

The sterilizing lamp 3 is located in the first mounting opening 21. Specifically, the sterilizing lamp 3 is mounted on the rear side wall of the inner container 12 through a lamp holder 32, and both ends of the sterilizing lamp 3 are mounted with bearings 31 and fixed with respect to the inner ring of the bearings 31. In this embodiment, the disinfection lamp 3 is a xenon lamp capable of generating a pulse flash with a wavelength of 200-1100 nm, and is used for efficiently disinfecting the disinfection cavity 121. The action mechanism of the pulse flash sterilization is the synergistic action of all wave bands in a spectral range, and is mainly embodied in three aspects:

(1) photochemical reaction in ultraviolet band: when the microorganism is irradiated by ultraviolet light in the pulsed intense light spectrum, thymine and cytosine in nucleic acid substances (DNA and RNA) generate photochemical reaction to generate dimers, so that the nucleic acid substances of the microorganism are damaged);

(2) flash heating effect: when per cm²When the peak power of the area reaches more than 1000W, the microorganisms are heated>At 100 ℃, because the flash irradiation time is extremely short, microorganisms can not be cooled normally, so that cell walls are broken and melted to die;

(3) pulse effect: the penetration of the intense pulsed light and the transient high energy mechanical impact damage the cell walls and other cellular components, resulting in bacterial death.

The reflector 4 is sleeved on the periphery of the disinfection lamp tube 3 and can reflect the disinfection light emitted by the disinfection lamp tube 2. Specifically, the two ends of the reflector 4 are provided with end caps 42, and the end caps 42 are sleeved on the bearing 31 and fixed relative to the outer ring of the bearing 31; an opening 41 extending along the length direction of the disinfection lamp tube 3 is formed on the side wall of the reflecting cover 4, and the upper and lower side edges of the opening 41 are respectively bent outwards and extend to form a first convex edge 43 and a second convex edge 44; the peripheral wall of the reflector 4 is locally pressed inwards to form a plurality of bosses 45 which are arranged at intervals, and the outer perimeter of the cross section of each boss 45 is gradually reduced from the inner wall of the reflector 4 to the end part of each boss 45, so that the sterilizing light rays are diffused and reflected in multiple angles, and the dead angle of the light ray intensity is avoided. In this embodiment, the reflector 4 is made of a specular aluminum plate with high reflectivity.

The working principle of the invention is as follows:

(1) when the layered disinfection cabinet works:

firstly, when the first chamber 1211 needs to be disinfected independently, the driving mechanism 5 drives the reflector 4 to move to the first state as shown in fig. 4, at this time, the opening 41 of the reflector 4 only faces the first chamber 1211, the disinfecting light emitted by the disinfecting lamp tube 3 directly acts on the first chamber 1211 or only acts on the first chamber 1211 under the reflection of the reflector 4, the first convex edge 43 abuts against the inner wall of the inner container 12 above the second mounting opening 122, and the second convex edge 44 abuts against the bottom wall of the partition plate 2 in front of the first mounting opening 21;

when the second chamber 1212 needs to be sterilized separately, the driving mechanism 5 drives the reflecting cover 4 to move to the second state shown in fig. 5, at this time, the opening 41 of the reflecting cover 4 only faces the second chamber 1212, the sterilizing light emitted by the sterilizing lamp tube 3 directly acts on the second chamber 1212 or is reflected by the reflecting cover 4, the first convex edge 43 abuts against the top wall of the partition plate 2 located in front of the first mounting opening 21, and the second convex edge 44 abuts against the inner wall of the liner 12 located below the second mounting opening 122;

when the first chamber 1211 and the second chamber 1212 need to be disinfected simultaneously, the driving mechanism 5 drives the reflector 4 to move to the third state as shown in fig. 6, at this time, the opening 41 of the reflector 4 faces the first chamber 1211 and the second chamber 1212, the disinfecting light emitted by the disinfecting lamp tube 3 directly or under the reflection of the reflector 4 acts on the first chamber 1211 and the second chamber 1212 simultaneously, and meanwhile, the driving mechanism 5 can drive the reflector 4 to reciprocate between the first state and the second state, so that the irradiation angle and range of the disinfecting light are changed, and the disinfecting chamber 121 is irradiated and sterilized from multiple angles;

in addition, when drying is required, the heating pipe 22 inside the partition plate 2 is activated to dry the first and

second chambers

1211 and 1212 at the same time.

(2) When the layered disinfection cabinet finishes working:

firstly, when the first drawer 6 is pulled out from the first chamber 1211, as shown in fig. 7, the first drawer 6 releases the first contact 81 to open the first gate control switch 8, the second drawer 7 presses the second contact 91 to close the second gate control switch 9, the reflector 4 moves to the second state under the control of the control system, at this time, the opening 41 of the reflector 4 only faces the second chamber 1212, that is, the disinfection lamp 3 is not exposed in the first chamber 1211, so that the user can be prevented from colliding with the disinfection lamp 3 when taking and placing tableware in the first chamber 1211;

when the second drawer 7 is pulled out from the second chamber 1212, as shown in fig. 8, the second drawer 7 releases the second contact 91 to open the second gate control switch 9, the first drawer 6 presses the first contact 81 to close the first gate control switch 8, the reflector 4 moves to the first state under the control of the control system, at this time, the opening 41 of the reflector 4 only faces the first chamber 1211, that is, the sterilizing lamp tube 3 is not exposed in the second chamber 1212, so that the user can be prevented from colliding with the sterilizing lamp tube 3 when taking and placing tableware in the second chamber 1212.
