After the set time, the water pump 40 stops working to stop supplying water to the brush ring water channel 50, so that enough water is reserved in the water tank 60 for the water supply and drainage mechanism to normally drain water, and the flushing of the main flushing water channel is not influenced.
A third embodiment (when the water pressure of the inlet mechanism 20 is low, the water pump 40 and the switching mechanism 30 are provided at the same time, and the water is sprayed to the spray pipe 44 through the water pump 40):
as shown in fig. 7 to 8, the main difference between the present embodiment and the second embodiment is: the switching mechanism 30 of this embodiment can still be retained, and the same effect can be achieved by taking the nozzle 44 of the switching mechanism 30 off from the flushing water inlet 51 of the brush ring water channel 50, putting the nozzle 44 into the water tank 60, then connecting the water pump 40, and then connecting another nozzle 44.
When it is judged that the toilet bowl cleaning surface cannot be cleaned by the water inlet pressure of the water inlet mechanism 20: in addition, a water pump 40 is added, and water from the water inlet means 20 enters the switching means 30 through the connection pipe 35, and flows into the water tank 60 through the spray nozzle 43 or the spray pipe 44 provided in the switching means 30, thereby supplying water into the water tank 60. Then, the water pump 40 is operated, and the water pump 40 pumps the water in the water tank 60 out to spray to the other spray pipe 44 and then flows into the brush ring water channel 50, so as to clean the cleaning surface of the toilet.
In the above embodiments, the water pump 40 is the submersible pump 40, and the water inlet of the water pump 40 is located below the working water level of the water tank 60, but a centrifugal pump, an axial flow pump, or the like may be used instead, and the effect is the same as the above. The current water inlet pressure of the water inlet mechanism 20 can be detected by adopting additional detection equipment, such as a pressure gauge, so as to judge whether the current water inlet pressure of the water inlet mechanism 20 meets the requirement of cleaning the cleaning surface of the toilet, and whether the current water inlet pressure of the water inlet mechanism 20 can clean the cleaning surface of the toilet is judged according to the water inlet pressure of the water inlet mechanism 20, and the judgment can be carried out according to national standards, generally, when the water inlet pressure of the current water inlet mechanism 20 is less than or equal to 0.14MPa, the water inlet pressure of the water inlet mechanism 20 cannot clean the cleaning surface of the toilet, and at this time, the flushing system is set to be in the state shown in fig. 2 or fig. 6, and the water pump 40 supplies water to the brush ring water channel 50; if the water pressure of the water inlet means 20 is higher than 0.14MPa, the water pressure of the water inlet means 20 can wash the toilet cleaning surface, and the flushing system is set to the state shown in fig. 1 or 5, and the water is supplied from the water inlet means 20 to the brush ring water passage 50 through the switching means 30.
While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
