Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 4, the sterilizing cabinet includes:

the cabinet body 1 is a shell of the disinfection cabinet, the prior art can be selected according to needs, and the cross section of the cabinet body in the embodiment is circular and is a cylindrical cabinet body; a doorway 11 is arranged on the side wall of the cabinet body, and an arc-shaped door body 12 is hinged on the doorway 11.

A cover plate 14 is further arranged in the cabinet body 1, the cover plate 14 is arranged close to a bottom plate 15 of the cabinet body 1, and a cavity for accommodating the first driving device 4 and the second driving device 5 is formed between the cover plate 14 and the bottom plate;

tray 2, there are the multiunit, and this embodiment has three groups, and every group tray comprises a plurality of trays. Each tray in the same group of trays is connected to the three support rods 21 and is arranged at intervals along the height direction of the support rods; the lower end of the support bar 21 is connected to the base 22. The base rotates to drive the supporting rods to drive the trays to rotate.

An ultraviolet lamp tube 3; the hanging part is hung on the top plate of the cabinet body and is positioned in the axial direction of the inner cavity of the cabinet body; can radiate ultraviolet rays to irradiate the articles on the tray, and can generate ozone during ultraviolet ray irradiation. The ultraviolet lamp tube 3 can be any one of the prior arts according to the requirement.

The second driving device 5 is used for driving each base to rotate around the ultraviolet lamp tube 3; comprises a motor 51, wherein an output shaft of the motor 51 is in driving connection with a first connecting shaft 54, and the first connecting shaft 54 is in driving connection with a bracket 52 and a driving gear 42; the support is connected with three lifting arms 53, and each lifting arm 53 is respectively connected with the corresponding base 22 through a second connecting shaft 55 in a driving manner. The second connecting shaft 55 is also connected with a slide block 56 in a driving way; the sliding block 56 is provided with a sliding groove 59; the bottom plate of the cabinet body 1 is provided with a circular slide rail 57, and the slide grooves 5 on the slide blocks 56 can be slidably clamped and sleeved on the slide rail 57.

The cover plate 14 is provided with holes matched with the bases 22; each base 22 is rotatably received in a respective one of the corresponding apertures.

Three groups of first driving devices 4 are respectively used for driving the bases 22 corresponding to the first driving devices to rotate; each including a driven gear 41, each driven gear 41 being engaged with the driving gear 42; the first connecting shaft 54 is drivingly connected to the drive gear 42.
