Description

Technical Field

[0001] This invention relates to the field of disinfection equipment technology, and more specifically, to a spray disinfection robot. Background Technology

[0002] Existing spraying robots are devices that can be used to spray disinfection on the surrounding environment. They can autonomously determine or remotely select the mode of movement during the spraying process based on the environment and route.

[0003] A search revealed an intelligent spraying robot with publication number CN116531543B, relating to the field of disinfection equipment technology. The robot includes a main body, a guide frame, casters, and a diffusion mechanism. This invention, by setting up a diffusion mechanism and driving an opening / closing component via a drive mechanism, automatically exposes the nozzles on the guide frame. A speed-increasing component drives a fan to rotate while moving along the outer wall of the guide frame. A water pump is activated to deliver liquid hydrogen peroxide from the tank to the nozzles through pipes. The hydrogen peroxide is then sprayed as a water mist outwards from the guide frame. Simultaneously, the water mist is propelled further by the fan, effectively increasing the spray range. After disinfection of the surrounding environment, the reverse drive of the drive mechanism is stopped, automatically covering the opening of the guide frame and preventing dust accumulation and blockage of the nozzles when not in use.

[0004] However, when the intelligent spraying robot is used for outdoor disinfection, it does not have the function of stirring the disinfectant solution. Over time, the disinfectant solution inside will separate into layers, reducing the disinfection effect. Summary of the Invention

With the help of a reset spring, the piston moves back and forth in a piston cylinder, thereby drawing disinfectant from the disinfection tank into the piston cylinder through a suction pipe and discharging it back into the disinfection tank through an L-shaped outlet pipe.

The guide 14 is placed in the guide groove 31, so that the rotating shaft 45 on it passes through the shaft hole 44 and extends into the interior of the disinfection box 8. The retaining rail 49 inside the stirring shaft 15 is engaged in the retaining groove 50 on the rotating shaft 45.
