Description

Multifunctional cleaning robot for washing and killing floor

Technical Field

The utility model belongs to the technical field of the sanitary clean service and specifically relates to a wash multi-functional cleaning machines people that disappears and kills.

Background

The emergence of novel coronaviruses brings huge losses to global economy and personal safety, guarantees the life safety of first-line medical workers and sanitary cleaning personnel, timely treats virus and bacteria in the air and pollutants on the ground, and is particularly important for blocking the propagation and the diffusion of pollution sources as far as possible. However, most of the robots currently put into practical use can perform only a single sterilization or floor cleaning function. The cleaning robot can only clean the ground, and virus and bacteria in the surrounding air can be adhered to the surface of the robot to cause pollution diffusion; secondly, the disinfection robot can only achieve the disinfection function aiming at the virus and bacteria in the air, only after the disinfectant lands on the ground, the residual pollutants on the ground can be killed, and the disinfection effect can be obviously reduced as the disinfection capability is reduced in the process of the disinfectant landing; meanwhile, after the disinfectant is inactivated, virus and bacteria in the small liquid drops can be adhered to the air and fall on the ground surface, and if the ground is not cleaned in time, the small liquid drops can be adhered to the bottom of the robot to cause pollution; in addition, since the robot does not have a cleaning function, the chassis or wheels may be in contact with the contaminants on the ground to cause the contaminants to spread. Therefore, the robot is likely to carry viruses after the floor washing or disinfection and sterilization work is finished, and is not beneficial to comprehensively and effectively executing disinfection and epidemic prevention work.

The existing public health service robot has less design of integrating floor cleaning and disinfection and sterilization functions, and a Chinese patent CN201811043994.X proposes a decontamination robot which comprises a moving device and a spraying device of the decontamination robot.
