Abstract
The utility model discloses a water flow sensor. The water flow sensor comprises a shell body, a Hall element and a rotor assembly, wherein the rotor assembly is arranged inside the shell body and comprises a rotor shell body, a magnetic rotor, a water inlet end cover, a water outlet end cover and a non-return sleeve, the magnetic rotor is arranged inside the rotor shell body, the water inlet end cover and the water outlet end cover are arranged at the two ends of the rotor shell body in a detachable mode, the two ends of a rotation shaft on the magnetic rotor are inserted into a supporting sleeve at the circle center of the water inlet end cover and a supporting sleeve at the circle center of water outlet end cover, an axial smooth protrusion is arranged at the inner end portion of each supporting sleeve, and the non-return sleeve is arranged on the water outlet end cover. The water flow sensor has the advantages of being reasonable in structure, convenient to install, low in cost, high in sensing accuracy and the like.
Description
Technical field
The utility model relates to a kind of sensor, and is especially relevant with water flow sensor.
Background technology
Water flow sensor is the vitals of domestic gas-fired water heater, existing water flow sensor, due to intake end cover and the water outlet end cap is unreasonable with the rotor case connected mode, the supporting sleeve inner end is that one-sided steel ball is connected with the rotating shaft movable contact of magnet rotor, reduced precision and dirigibility that magnet rotor rotates, existed complex structure, the deficiencies such as difficult, that sensing accuracy is low are installed.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, easy for installation, low high water flow sensor of sensing accuracy that reaches of cost.
For achieving the above object, the utility model is achieved through the following technical solutions.Water flow sensor, comprise housing, Hall element and rotor assembly, rotor assembly is located in housing, rotor assembly comprises rotor case, magnet rotor, intake end cover, water outlet end cap and check cover, magnet rotor is located in rotor case, the detachable rotor case two ends of being located at of intake end cover and water outlet end cap, rotating shaft two ends on magnet rotor are inserted and are located in the supporting sleeve in intake end cover and the water outlet end cap center of circle, at the supporting sleeve inner end, be equipped with axial smooth bumps, check is sheathed on water side and covers.
Described water flow sensor, at the rotor case two ends, be respectively equipped with cooperation step and mouth of connecting trough, intake end cover and water side cover correspondingly to be provided with and coordinate inner ring and connect convex tendon, coordinate step to match with coordinating inner ring, simultaneously, connecting convex tendon inserts in mouth of connecting trough.
Described water flow sensor, the connection convex tendon on its intake end cover are 1-3, and the connection convex tendon that water side covers is 2-20.
Utility model compared with prior art has the following advantages: (one) is due to intake end cover and the detachable rotor case two ends of being located at of water outlet end cap, makes to process simple, easy to assembly, production cost reduction; (2) be owing at the supporting sleeve inner end, being equipped with axial smooth bumps, cancelled traditional single steel ball structure, make simultaneously the supporting balance of magnet rotor, not only assembling is light, and can greatly improve sensing accuracy.
