Description

Technical Field

[0001] The utility model relates to the technical field of float ball assemblies, in particular to a mechanical and magnetic induction float ball water stop valve assembly. Background Art

[0002] In the prior art, the mechanical water stop valves used in water purifiers, water dispensers, and other equipment with built-in water storage tanks are mostly float lever valves. These valves have numerous drawbacks. For example, to increase buoyancy, some levers are very long, and the floats are also very large. When the tap water pressure is too high, the levers are prone to bending, the lever connecting pins are subject to high stress and wear, the floats are prone to breaking or deforming when they strike the tank top, and the valve body's water-stop rubber is easily deformed and cut by the lever pressure. This can cause the water valve to not close properly, leading to long-term flooding. This not only causes waste but also increases the financial burden on users.

[0003] Existing sensor-type water stop valves also have the risk of failure due to circuit failure and other reasons, resulting in poor actual use effect.

[0004] There is a need for a mechanical and magnetic induction float water stop valve assembly that can solve the above-mentioned problems. Utility Model Content

[0025] Furthermore, to achieve the installation effect of the rotating assembly 3, the rotating assembly 3 includes a float connection part 31, a rotating shaft 32, and a protrusion 33. The float connection part 31 is fixedly connected to the float assembly 1. A through hole is provided in the middle of the float connection part 31. A mounting hole 41 is provided on the valve body 4. The rotating shaft 32 passes through the mounting hole 41 of the valve body 4 and the through hole to rotatably install the float connection part 31 on the valve body 4. The other end of the float connection part 31 facing away from the float assembly 1 is provided with a protrusion 33. The protrusion 33 is arranged to interfere with the sealing plug 6 installed in the valve body 4. The valve body 4 is provided with a mounting slot for the rotating assembly 3.

[0029] In this embodiment, the float assembly is rotatably installed on the valve body. When the water level rises, the float assembly rotates relative to the valve body, so that the rotating assembly installed on the upper end of the float assembly drives the sealing plug to move toward the water inlet, sealing the water inlet setting, so that the water inlet channel is closed and water cannot enter the water tank.

[0030] In this embodiment, a Hall sensor assembly is installed in the water tank, and a magnet is installed at the bottom of the float assembly. When the water level rises, the Hall sensor senses the magnet and determines that the water level has risen to a certain height, and sends a control signal to the main control system. The main control system controls the water pump of the external water supply equipment to turn off, cutting off the water supply from the water source, so that water cannot enter the water tank.

[0031] This application uses mechanical control and magnetic induction electronic control to stop water, avoiding water tank overflow and causing machine failure, which is safer and more stable, has a longer service life and enhances user experience.
