When the float part 51 rises with the rise of the liquid surface in the water tank 4, the driving part 52 descends to lower the valve body 21 until the valve body 21 moves to the first position, the water inlet flow passage 11 is blocked, and water cannot continue to flow into the water tank 4, and at this time, the upper surface of the float part 51 contacts the sealing part 131 to seal the water outlet on the water outlet structure 13. When the valve core assembly 2 fails, the water inlet flow channel 11 cannot be plugged, at this time, the water level in the water tank 4 will continuously rise, and when the water level rises to a certain position, the floating part 51 contacts with the sealing part 131 and applies pressure to the sealing part 131, so that the water outlet is plugged, water cannot continuously flow into the water tank 4, and water is prevented from overflowing.
In the second embodiment, as shown in fig. 2 and 5, the second end of the water inlet channel 11 is a closed end, and the water inlet channel 11 is configured as a barrel structure with an open first end and a closed second end. The second end of the valve core 21 is located in the water inlet flow channel 11, the second end of the valve core 21 is provided with a first magnetic component 24, correspondingly, in this embodiment, the driving part 52 of the float 5 is provided with a second magnetic component 521, and the first magnetic component 24 and the second magnetic component 52 can generate repulsive force, so that when the driving part 52 approaches the valve core 21, the valve core 21 can be pushed to move upwards, preferably, the first magnetic component 24 and the second magnetic component 52 are both magnets, and homopolar of the first magnetic component 24 and homopolar of the second magnetic component 52 are oppositely arranged when being installed.
The water outlet valve structure is provided with the water outlet flow passage, the end part of the water outlet flow passage is provided with the water outlet structure, the water outlet structure can be matched with the float in the water tank, and when the water level is too high, the float can seal the water outlet on the water outlet structure. Therefore, the water outlet valve structure is provided with double sealing for blocking the water inlet flow passage through the valve core assembly and blocking the water outlet through the floater, so that the reliability of the water outlet valve structure is improved.
It is easy to understand by those skilled in the art that the above preferred embodiments can be freely combined and overlapped without conflict.
It will be understood that the above-described embodiments are merely illustrative and not restrictive, and that all obvious or equivalent modifications and substitutions to the details given above may be made by those skilled in the art without departing from the underlying principles of the invention, are intended to be included within the scope of the appended claims.
