UVC ultraviolet ray has the dual function of surface disinfection and air disinfection simultaneously, extensively is used for indoor air and object surface disinfection in the hospital, plays important effect in prevention and control hospital infection work.

At present, the traditional ultraviolet disinfection mode is to install suspended ultraviolet lamps in each high risk area of a hospital, for example, after an operation is performed in an operating room and a patient is received in an infectious disease department, the ultraviolet lamps are immediately started to sterilize and disinfect the air and part of the object surface in the area. This method consumes manpower, and can not effectively disinfect corners, gaps and bottom of equipment, and is easy to store dirt and breed germs. Therefore, a disinfection robot is developed, the ultraviolet disinfection lamp holder is arranged on the automatic navigation carrier chassis, the ultraviolet lamp holder is driven to move through the chassis, multi-angle irradiation on the surface of an object can be realized, and the disinfection efficiency and quality are greatly improved. However, the current disinfection robot has the following three problems: first, single ultraviolet ray disinfection machine people accessible angle of adjustment shines the corner, nevertheless still can't disinfect to gap, equipment bottom this kind of dirty dirt of hiding department. Secondly, the disinfection robot mixed by disinfection liquid and ultraviolet mainly depends on disinfection liquid drops suspended in the air to contact the surface of an object under the action of gravity, and still cannot reach the bottom of the equipment; and the ultraviolet rays are refracted and scattered by the droplets of the suspension in the air, and the sterilizing power of the ultraviolet rays is greatly reduced. Thirdly, the existing ultraviolet disinfection trolley cannot detect the irradiation intensity of the carried disinfection lamp and record the service life of the disinfection lamp tube, so that the possibility that the disinfection robot continues disinfection operation under the condition that the lamp tube has longer service life and insufficient irradiation intensity exists, and the due disinfection effect cannot be achieved.

Effectively improves the efficiency and quality of ultraviolet disinfection and sterilization. The ultraviolet sensor monitors the ultraviolet intensity in real time, so that the phenomenon that only a single lamp tube of the disinfection robot can be normally used but the disinfection vehicle is still used for low-quality disinfection operation can be avoided, and workers are reminded to wipe the lamp tube or replace the lamp tube in time. Through the digital display accumulation timer, the condition that personnel uniformly record the disinfection time of the lamp tube can be avoided, after one lamp tube is replaced, the disinfection time of the other lamp tube in use is continuously accumulated according to the disinfection time of the other lamp tube, so that the actual use time of a new lamp tube is inconsistent with the registration time, the accumulated disinfection use time of the lamp tube cannot be accurately reflected, and the timer can not only reduce the labor of the personnel, but also accurately record the use time of the lamp tube.
