Description

Household disinfection cabinet

Technical Field

The invention relates to the field of disinfection cabinets, in particular to a household disinfection cabinet with high sterilization efficiency.

Background

Traditional sterilizer is under operating mode, and ultraviolet lamp all is in quiescent condition with the article of treating disinfecting, and there is the shadow face ultraviolet irradiation to article to there is the dead angle of disinfecting, influences the disinfection effect then. Therefore, the ultraviolet lamp can irradiate the articles to be disinfected more comprehensively by rotating the ultraviolet lamp, for example, chinese patent No. ZL200510092978.6 (publication No. CN1919349A) discloses a disinfection cabinet, which comprises a housing, a box body arranged in the housing, a door body, a partition frame arranged in the box body, and a control circuit, wherein a rotatable lamp holder for arranging an ultraviolet lamp tube is arranged at the top of the box body. Although this patent can be followed the disinfection dead angle problem of treating disinfection article to a certain extent through the rotation of ultraviolet lamp, the disinfection dead angle problem in the internal chamber of sterilizer still exists, and the existence at internal chamber disinfection dead angle of cabinet can lead to the fact secondary pollution to the disinfected article of holding in the internal chamber of cabinet to make the disinfection effect discount greatly. In addition, although the ultraviolet lamp is in a rotating state in the patent, the number of times of close contact of the ultraviolet lamp with the object to be sterilized is still limited, thereby further improving the sterilizing effect.

Disclosure of Invention

The invention aims to solve the first technical problem of providing a household disinfection cabinet with high sterilization efficiency aiming at the prior art.

The second technical problem to be solved by the invention is to provide a household disinfection cabinet which is convenient to use aiming at the prior art.

The second technical problem to be solved by the invention is to provide a household disinfection cabinet capable of collecting water in a cabinet body aiming at the prior art.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a household disinfection cabinet, includes the cabinet body and articulates the door body on the annular opening of the cabinet body, a serial communication port, be provided with supporter and the ultraviolet lamp who is used for placing the tableware of treating disinfecting in the cabinet body respectively in the cabinet body, this supporter sets up at the middle part of the cabinet body, and it includes the rotation axis of vertical setting on the internal bottom surface of cabinet, is provided with the annular spout of circle on the cabinet body diapire, and this spout sets up and lies in the periphery of supporter as the center with above-mentioned rotation axis, and the vertical setting of above-mentioned ultraviolet lamp can be followed this spout circumferential direction in this.

In order to enable the ultraviolet lamp to smoothly rotate along the circumferential direction of the sliding chute, a driving motor is arranged in the sliding chute, guide plates are respectively fixed on two sides of a shell of the driving motor, each guide plate is an arc plate concentric with the sliding chute, and the two guide plates are respectively attached to the inner and outer chute walls of the sliding chute; the top of the casing is provided with a power output shaft which vertically extends upwards, a horizontally placed driving gear is fixed on the power output shaft, the ultraviolet lamp is installed on the driving gear, a circular ring-shaped gear ring is arranged on the inner bottom surface of the cabinet body on one side of the sliding groove, the gear ring and the sliding groove are concentrically arranged, and the driving gear can be meshed with a tooth surface on the gear ring. Thus, the driving motor is transmitted to the driving gear, the driving gear rotates, and the driving gear is meshed with the tooth surface on the gear ring, so that the ultraviolet lamp rotates along the circumferential direction of the sliding groove.

For making sterilizer inner structure set up more rationally, cabinet body bottom is fixed with the annular body of circle, the open-top of this body, and its inner chamber constitutes above-mentioned spout, sets up the annular opening that corresponds with the notch of spout on the cabinet body diapire, power output shaft inserts and establishes in this annular opening, and above-mentioned drive gear is located annular opening top, and above-mentioned ring gear setting is in annular opening's inboard or outside.
