Description

Technical Field

[0001] The utility model relates to the technical field of water heater accessories, in particular to an impeller water-gas linkage valve structure. Background Art

[0002] Water heaters are common appliances in daily life. Existing water heaters require a water inlet sensor installed on the water inlet valve. When water enters the inlet, the sensor sends a signal to control the heating element, thereby preventing the risk of burnout. Existing water inlet sensors typically incorporate a magnetic axial slide within the inlet valve. When the inlet valve is opened, water flow pushes the slide toward the rear end of the valve. The magnetic sensor detects the slide at the rear end of the valve, indicating that the valve is open and controlling the heating element.

[0003] However, the aforementioned water inlet sensing component, with its axial sliding post located inside the water inlet valve, requires high processing requirements, as well as high sealing and waterproofing requirements for the water inlet valve, necessitating a high level of manufacturing process. Furthermore, the axial sliding post exerts its own gravity, requiring water pressure to reach a certain level in order to propel it forward. Consequently, when the water inlet valve is narrowly opened or the water flow is low, the water inlet sensing component exhibits poor sensitivity. Therefore, further improvements are needed.

[0030] The water valve body 10 is also provided with a water inlet sensing structure; the water inlet sensing structure includes an impeller assembly 50 and a Hall sensor 60; the impeller assembly 50 includes an impeller body 51 and a magnetic trigger 52; the axis of the impeller body 51 is perpendicular to the channel axis of the water valve body 10; when water flows in the water valve body 10, the impeller body 51 and the magnetic trigger 52 rotate synchronously and are sensed by the Hall sensor 60.

[0031] In the present invention, the rotation of the impeller body 51 drives the magnetic triggering member 52 to rotate synchronously, thereby causing the Hall sensor 60 on the outside to generate a magnetic field induction, thereby sensing and judging the size of the water flow; the impeller body 51 only requires a small water flow pressure to be pulled to rotate, and can also detect smaller water flows, with high detection sensitivity; and the Hall sensor 60 is arranged on the outside of the water inlet end, which significantly reduces the sealing and processing requirements; in addition, the axis of the impeller body 51 is perpendicular to the channel axis of the water valve body 10, and the vertical action surface of the water flow is used to drive the impeller to rotate, and the impeller body 51 is not easy to get stuck.

[0032] Specifically, the impeller assembly 50 also includes an impeller shaft 53 and an impeller support cover 54. The water valve body 10 is provided with an impeller mounting seat 11, which has an opening on one side. The impeller support cover 54 can block the opening of the impeller mounting seat 11. One end of the impeller shaft 53 is fixed to the impeller mounting seat 11, and the other end is fixed to the impeller support cover 54. The impeller body 51 is rotatably mounted on the impeller shaft 53, and the magnetic trigger 52 is fixed to the impeller body 51. The Hall sensor 60 is installed near the impeller mounting seat 11.

[0036] In this embodiment, the valve body 20 is further provided with one or more solenoid valves. Preferably, two solenoid valves are spaced apart from each other. The two solenoid valves operate independently of each other.
