[0001] The invention relates to the field of sanitary ware, and in particular to a device and method capable of inhibiting aerosol transmission and disinfection, and a toilet. Background Art

[0002] The emergence of toilets has brought great convenience to people's lives, but at the same time, the following problems have also emerged: in the process of flushing excrement, the strong flushing force of the toilet easily produces aerosols containing excrement viruses and bacteria. Once the aerosol enters the human body, it will be very harmful to human health and even threaten human life. Although many users are accustomed to closing the toilet cover before flushing after defecation, this cannot effectively inhibit the spread of the above aerosols. The aerosols will still remain in the toilet and escape and spread after the toilet cover is opened.

[0003] Toilets in the prior art generally do not have a disinfection function, which means that once pathogenic viruses are present in excrement, these pathogenic viruses are likely to remain on the inner wall of the toilet and enter the human body through transmission, thereby posing a threat to human health and even life safety.

After the user has used the toilet, the water curtain nozzle 1 is used to spray a water curtain covering the inner wall of the toilet, thereby covering the excrement in the toilet, and the water curtain is continuously sprayed, and at least continues until the toilet is flushed, thereby inhibiting the excrement aerosol generated by the flushing of the toilet from spreading outward; after the toilet is flushed, the inner wall of the toilet is disinfected to avoid pathogenic viruses on the excrement remaining on the inner wall of the toilet. The water curtain can cover the entire inner wall of the toilet, or only cover a part of the inner wall of the toilet, as long as it can cover the excrement in the toilet.

[0040] In this embodiment, Figure 2-Figure 4 As shown, the switching mechanism 3 includes a switching body and a sealing gasket 33. The switching body is provided with a first channel 311 connected to the disinfectant storage container 10, a second channel 312 connected to the inlet of the liquid pump 2, and a third channel 321 connected to the water outlet end of the water pipe 20. The first channel 311, the second channel 312, and the third channel 321 are interconnected, and the sealing gasket 33 is movably arranged at the connection point. The sealing gasket 33 is hydraulically pushed to block the first channel 311 or the third channel 321.

The water curtain nozzle 1 sprays a water curtain covering the inner wall of the toilet body 50, and the water curtain nozzle 1 continues to spray, and at least continues until the toilet is flushed;

[0053] 2) After the toilet is flushed and the control valve (i.e., the two-position electromagnetic switching valve 4) switches the water pipe 20 to the water-off state, the disinfectant is pumped from the disinfectant storage container 10 to the water curtain nozzle 1 through the switching mechanism 3 by the liquid pump 2, and the disinfectant is evenly sprayed on the inner wall of the toilet body 50 by the water curtain nozzle 1.

[0054] 3) After the disinfection is completed, the control valve switches the water pipe 20 to the water inlet state again, and the liquid pump 2 is not started.

[0055] 4) After cleaning is completed, the flushing function of the toilet is activated to drain away the disinfectant sprayed on the inner wall of the toilet body 50.

[0056] In the step 1), the water curtain starts to be sprayed several seconds (e.g., 2 seconds) after the person leaves the seat, and the toilet starts to flush several seconds (e.g., 4 seconds) after the water curtain is sprayed. In the step 2), the disinfectant starts to be sprayed several seconds (e.g., 2 seconds) after the toilet finishes flushing. The disinfectant can be a diluted 84 disinfectant or KMnO4 disinfectant. The control panel 6 determines the user's defecation and urination behavior according to the user's sitting time, and controls the spraying amount of the disinfectant (i.e., the working time of the liquid pump 2) and / or the disinfection time (i.e., the residence time of the disinfectant on the inner wall of the toilet body 50) according to the defecation and urination behavior. For example, for defecation behavior, the spraying amount of the disinfectant is 10 ml each time, and the disinfection time is 20 minutes. For urination behavior, the spraying amount of the disinfectant is 5 ml each time, and the disinfection time is 10 minutes.
