Description

Disinfection cabinet

Technical Field

The invention relates to the technical field of kitchen equipment, in particular to a disinfection cabinet.

Background

At present, the drawer in the drawer cabinet is installed to be opened in a pull-out type or a touch bounce type. The pull-out type is that the drawer is pulled by hands to slide back and forth along the sliding rail, the method has a simple structure, but the pull handle is required to be arranged on the drawer; the touch bounce-back type finger pushes the drawer inwards to apply pressure on the bounce-back device and automatically pops the drawer after moving for a certain distance.

For example, the utility model patent with the patent application number of CN202022180015.4 (publication number of CN213820563U) discloses an automatic popping silent drawer slide rail structure, which comprises a box body, a drawer, a slide rail and a rebound damping mechanism, sliding rails are fixedly arranged on two sides of the interior of the box body, a drawer is fixedly arranged at the inner side ends of the sliding rails, the rear end of the slide rail is fixedly welded with a rear frame and a front frame, the upper end of the slide rail is provided with an upper rail, the lower end of the slide rail is connected with a middle rail in a sliding way, the bottom of the middle rail is connected with a rebound damping mechanism in a sliding way, the bottom of the rebound damping mechanism is connected with a bottom rail in a sliding way, the front end of the slide rail is fixedly connected with the rebound damping mechanism through a first slide rail buckle and a second slide rail buckle in a welding way, the bottom of the inner side of the rebound damping mechanism is provided with a damping tube, and the upper end of the damping tube is provided with a damping spring.

However, the drawer opening mode in current sterilizer is still mostly pull out formula because the sterilizer is higher to the sealed requirement when the drawer is closed, if the drawer opening mode design in the sterilizer is touching bounce-back formula, because touching bounce-back formula need move one end distance to bounce-back device when opening the drawer, must leave certain stroke of pressing for the drawer, can influence the sealed effect of sterilizer like this. Regarding to the technical problem, the applicant thought that a sealing ring is arranged between a cabinet body and a drawer of a disinfection cabinet, when the drawer needs to be opened, a user can push one end of the drawer inwards to compress the sealing ring, meanwhile, the rebound device is pressed, and finally, the automatic ejection of the drawer is achieved.
