After the spraying reaches the set time, the ultrasonic atomization device 3 and the centrifugal delivery pump 4 are closed, and the electric control valve in the urinal and toilet room is closed.
[0030] Embodiment 4, as Figure 4As shown, the system for implementing the automatic detection and disinfection method for toilet use to avoid the spread of pathogens of the present invention is different from the above-mentioned embodiment three in that: a washing human body detector 54 and a flushing human body detector 55 are respectively arranged on the rear wall of the washbasin and the rear wall of the mop flushing pool of the toilet, when the human body sensors 52, 53 in the urinal and defecation rooms and the washing human body detector 54 and the flushing human body detector 55 sense the human body and lose the human body signal within a set time length, the intelligent controller 1 prohibits the main spray electric control valve 72 from starting and prohibits the ultrasonic atomization device 3 and the centrifugal delivery pump 4 from starting synchronously therewith. It can also be further configured as follows: a wash position human detector and a wash position spray head connected to the atomized disinfectant liquid delivery pipe through the wash position electric control valve pipe are arranged on the rear wall of the wash basin in the bathroom; a flushing position human detector and a flushing position spray head connected to the atomized disinfectant liquid delivery pipe through the flushing position electric control valve pipe are arranged on the rear wall of the mop washing pool; when each wash and flushing position human body sensor detects a human body and then loses the human body signal, the intelligent controller opens the electric control valve at that position, opens the ultrasonic atomization device and the centrifugal delivery pump, and closes the main spray electric control valve to spray the atomized disinfectant liquid; after the spray reaches the set time, the ultrasonic atomization device and the centrifugal delivery pump are closed, and the electric control valve at that position is closed.
[0031] Embodiment 5, as Figure 5 As shown, the difference between the system for implementing the automatic detection and disinfection method for toilet use to avoid the spread of pathogens of the present invention and the above-mentioned embodiment 4 is that: a plurality of door human detectors 5 arranged along the entry and exit direction are set at the toilet door, and the intelligent controller 1 determines the entry and exit direction, number and retention situation of people according to the strength and time sequence of the human body signals sensed by the plurality of door human detectors 5; an electronic prompt screen 8 electrically connected to the intelligent controller 1 is set at the toilet door, and when the main spray electric control valve 72 is opened, the electronic prompt screen 8 displays relevant prompt information that it is not appropriate to enter the toilet.
[0032] The application scenario of toilet disinfection is: by calculating the human body detector at the door of the human flow sensing element and the intelligent controller, the number of people using the toilet is counted. When a certain number of people is reached (adjustable) and it is determined that there is no one in the toilet, the disinfection device of the present invention is started to automatically spray and disinfect the public area in the toilet through the regional spray head.
[0033] The operation mode of disinfection of toilets, toilet seats and other points: 1. Tap water passes through a self-priming mixing device, mixes the disinfection raw materials with water in proportion, and then enters the disinfectant production machine. 2. After being produced by the disinfectant production machine, a disinfectant solution is produced. 3. The disinfectant solution enters the ultrasonic atomization device through the liquid level pressure, atomizes the disinfectant into tiny particles, and the atomized disinfectant is sent to the terminal control valve through a pipe through a silent centrifugal delivery pump. 4. When the human body sensor of the terminal control valve senses that a person has left the toilet, the intelligent controller sends a signal to the terminal control valve and opens the terminal control valve. The atomized disinfectant enters the high-speed atomization point spray head through the terminal control valve, and is sprayed directly from the top or wall side to the ground and toilet, forming a three-dimensional disinfection. A single toilet room, toilet seat or other spraying position will be disinfected within 2-3 seconds.
[0034] In summary, the automatic toilet detection and disinfection method and system for avoiding the spread of pathogens of the present invention have the advantages of being able to kill pathogens in a timely manner, effectively preventing the spread of pathogens, and not affecting the normal use of the toilet, and having good reliability.
