Description

Technical Field

[0001] This utility model relates to the field of water flow sensor technology, and in particular to a flow guide tube structure for a water flow sensor. Background Technology

[0002] Water flow sensors, as key components for detecting parameters such as water flow velocity and flow rate, are widely used in various water-related devices such as water heaters, water purifiers, smart water meters, and wall-hung boilers. Their performance directly affects the operational stability and safety of the entire water-related equipment. The flow guide tube, as a core component of the water flow sensor, primarily guides the water flow steadily through the magnetic rotor, ensuring that the magnetic rotor rotates accurately with the water flow. The rotation state of the magnetic rotor directly determines the accuracy of the sensor's detection of water flow parameters. Therefore, the rational design of the flow guide tube structure and the magnetic rotor is a crucial prerequisite for ensuring the overall performance of the water flow sensor.
