Description
Technical Field
The utility model belongs to the technical field of bathroom cleaners and polishes, specifically provide a closestool that prevents aerosol and splash.
Background
When the closestool is flushed, instantaneous cyclone is formed due to the impact of water flow in the closestool, and a large amount of aerosol is generated. Since viruses or bacteria can be transmitted through the aerosol, the aerosol generated by the flushing of the toilet can entrain pathogenic microorganisms in the excrement and suspend them in the air. Because there are large gaps between the toilet lid and the toilet seat, and between the toilet seat and the upper edge of the toilet base, even if the toilet lid is closed and water is flushed, these pathogenic microorganisms cannot be prevented from diffusing out with the aerosol. Moreover, at present, in most families, the toilet, the washing and the shower are carried out in a toilet, and the toothbrush, the tooth glass, the towel and the like are in the same room with the toilet, so that the pollution of pathogenic microorganisms in the aerosol is easy to happen. The risk of infection of diseases via the mucosal route is further increased by the presence of pathogenic microorganisms on the surfaces of these articles of daily use. Therefore, aerosol formed in the flushing process of the closestool is prevented from volatilizing outside the closestool, and sewage liquid drops are prevented from splashing outside the closestool, so that pathogenic bacteria and viruses in excrement can be inhibited from spreading and spreading.
In order to eliminate the pollution of pollutant droplets to the environment and articles and the influence on the human health when the toilet flushes excrement, the Chinese utility model with the publication number of CN209854861U discloses a toilet bowl for preventing environmental pollution. As shown in fig. 1, the environmental pollution prevention toilet comprises a toilet bowl 1 and a water curtain generating device, wherein the water curtain generating device comprises a water curtain spray head 10, a water curtain valve 12, a water curtain valve button 13 and a water pipe 14; wherein, the water curtain shower nozzle 10 is located the drain outlet 5 top in squatting pan 1 and fixed mounting is on seting up the urinal inner wall in squatting pan 1, and water pipe 14 sets up in water tank 7, and the water inlet port of water curtain shower nozzle 10 is connected to water pipe 14 one end, and the water curtain valve 12 in the water tank 7 is connected to the other end, is equipped with the water curtain valve button 13 that is used for controlling water curtain valve 12 to open on the tank lid 8.

It should be noted that, this embodiment is only an exemplary illustration of a typical structure of the water tank and the flushing device and the working principle when cooperating with the above-mentioned toilet, it can be understood that this exemplary illustration does not limit the protection scope of the present invention, and on the basis of satisfying the assembly process, the present invention can also cooperate with the water tank and the flushing device of other structures.
In addition, when the toilet of the present invention is used with the water tank 4 and the flushing device, the liquid storage tank 30, the liquid guide tube 31 and the switch valve 32 can be arranged independently of the water tank 4 and the flushing device, for example, the liquid storage tank 30 is directly and fixedly mounted on the wall of the toilet. Of course, the reservoir 30, the liquid guiding tube 31 and the switch valve 32 may also be installed in the water tank 4, for example, the reservoir 30 is fixedly installed in the water tank 4, the upper port of the liquid guiding tube 31 is communicated with the reservoir 30 through the switch valve 32, the lower end thereof penetrates the water tank 4 in a sealing manner and extends into the flushing water channel 10, and a button for controlling the opening or closing of the switch valve 32 is installed on the tank cover 41.
Further, in order to enhance the water pressure flowing into the flushing channel 10, the toilet of this embodiment may further include a booster pump, a high pressure side of which is connected to the water inlet 14 of the toilet base 1, and a low pressure side of which is used for boosting the flushing water source and then pressing into the flushing channel 10. Specifically to the toilet in this embodiment used with a cistern and flush device, the high pressure side of the booster pump is connected to the inlet 14 of the toilet base 1 by a pipe and the low pressure side is connected to the outlet of the tank 40 by a pipe. With such arrangement, when the operating handle 50 controls the drain valve 56 to open, the water in the tank 40 flows into the booster pump, flows into the flush water channel 10 after being pressurized, and is finally sprayed into the urinal 11 through the flush hole 100 and the water curtain nozzle 2.
