Description

Technical Field

[0001] This invention relates to the field of cleaning device technology, and in particular to an intelligent cleaning device and its control method. Background Technology

[0002] Infectious diseases are a class of diseases caused by various pathogens that can be transmitted between humans, animals, or between humans and animals. Most pathogens are microorganisms, while a small portion are parasites; diseases caused by parasites are also called parasitic diseases. For some infectious diseases, disease control departments must promptly monitor the incidence and take timely countermeasures. Therefore, upon discovery, they should be reported to the local disease control department within the prescribed time; these are called legally notifiable infectious diseases. In offices and public places with high pedestrian traffic, if people do not wear disposable protective gloves or disinfect door handles when opening them, infection can easily occur through the door handles. Providing disposable gloves or disinfecting door handles every time a door is opened significantly increases the use of gloves and disinfectants, and is inconvenient. Assigning dedicated personnel to supervise disinfection increases costs and the risk of infection for staff. Summary of the Invention

[0039] The central axes of the two sets of connecting parts 3 coincide with the central axis of the drive part 8. The two sets of connecting parts 3 are respectively connected to the outer handle 5 and the inner handle 6. The central axes of the outer handle 5 and the inner handle 6 are perpendicular to the central axis of the connecting parts 3. The inner handle 6, the outer handle 5, the drive part 8 and the two sets of connecting parts 3 constitute the installation part for installing the intelligent sterilization component.

In actual use, the one located outside the room where the door body 1 is installed is the outer handle 5, and the one located inside the room where the door body 1 is installed is the inner handle 6.

[0040] In one embodiment of the present invention, when in use, the mechanical lock body 2 is installed on the door body 1. When powered on, the intelligent sterilization component is provided to sterilize and clean the inner handle 6 and the outer handle 5 after people use them, thereby avoiding cross-infection caused by different pedestrians when using the inner handle 6 and the outer handle 5 to open the door, and effectively preventing the further spread of infectious diseases.

[0041] In an optional embodiment, the intelligent sterilization component includes two sets of first ultraviolet sterilization modules 4, two sets of second ultraviolet sterilization modules 7, wires 9, a first circuit board 10, a second circuit board 11, and two sets of end caps 13; wherein, the inner handle 6, the outer handle 5, and the drive unit 8 are all hollow structures, and the interiors of the inner handle 6, the drive unit 8, and the outer handle 5 are sequentially connected to form a wire-through-powered passage for the wires 9 to pass through.

When the intelligent sterilization component is powered on, the first main controller, the second main controller, the second ranging module 12, the first ranging module, the two sets of first ultraviolet sterilization modules 4 and the two sets of second ultraviolet sterilization modules 7 are all in operation.

[0055] S2, the first and second main controllers start timing; after the timing ends, both sets of first ultraviolet sterilization modules 4 and both sets of second ultraviolet sterilization modules 7 stop running;

[0056] S3. Determine whether the second ranging module 12 or the first ranging module has detected a pedestrian;

[0063] Furthermore, if only the first ranging module detects a pedestrian and determines that the pedestrian has left, then only two sets of the first ultraviolet sterilization modules 4 will operate to disinfect the outer handle 5 after the pedestrian has used it.

[0064] If only the second ranging module 12 detects a pedestrian and determines that the pedestrian has left, then only the two sets of second ultraviolet sterilization modules 7 will operate to disinfect the inner handle 6 after the pedestrian has used it, thus avoiding the two sets of first ultraviolet sterilization modules 4 or two sets of second ultraviolet sterilization modules 7 from running in vain and saving energy.

[0065] The intelligent cleaning device control method provided by the present invention can intelligently monitor pedestrians and intelligently control the two sets of first ultraviolet sterilization modules 4 and two sets of second ultraviolet sterilization modules 7 to operate simultaneously or operate individually to disinfect the inner handle 6 or the outer handle 5, thereby avoiding cross-infection caused by different pedestrians using the inner handle 6 or the outer handle 5 to open the door 1, and thus preventing the spread of diseases.
