Abstract
The utility model provides a water flow sensor, connects open -ended casing, magnet rotor, magnetism spider, hall sensor and rectification piece about having, and magnetism spider sets up in the casing, and hall sensor sets up on the casing, and the magnet rotor setting is on magnetism spider, and the rectification piece sets up the bottom of casing, magnetism spider's lower extreme and the cooperation of rectification piece, the rectification piece includes cylindric seat and roof, there is a plurality of stationary flow hole evenly distributed on the roof. Owing to adopt such structure, stationary flow spare makes rivers evenly pass through, and it is unanimous to keep getting into the interior water flow direction of magnetism spider to making drive magnet rotor water flow direction unanimous, reaching the magnet rotor and operate steadily, incoming signal is stable.
Description
Technical field
The utility model relates to a kind of water flow sensing unit.
Background technology
Currently available technology, a kind of water flow sensing unit, comprise the housing, magnet rotor, magnet rotor support, Hall element, rectification circle and the rectifier that have and connect opening up and down, magnet rotor Bracket setting is in housing, Hall element is arranged on housing, and magnet rotor is arranged on magnet rotor support, and rectifying component arranges the bottom of housing, the lower end of magnet rotor support coordinates with rectifying component, and rectifier is arranged on the bottom of rectifying component; Described rectification circle comprises cylindrical seat and tip circle ring flat-plate.Existing problems are: when discharge changes, and because feed water flow is to difference, cause inductive impulse deviation of signal large.
Utility model content
The purpose of this utility model is: provide a kind of water flow sensing unit, and it has when discharge changes, and keeps feed water flow to identical, the pulse signal of stable output.
The utility model is achieved in that a kind of water flow sensing unit, comprise the housing, magnet rotor, magnet rotor support, Hall element and the rectifying component that have and connect opening up and down, magnet rotor Bracket setting is in housing, Hall element is arranged on housing, magnet rotor is arranged on magnet rotor support, rectifying component arranges the bottom of housing, and the lower end of magnet rotor support coordinates with rectifying component; Its special character is: described rectifying component comprises cylindrical seat and top board, described top board has several current stabilization holes be uniformly distributed.
Described a kind of water flow sensing unit, its special character is: described current stabilization hole is rounded;
On current stabilization pore size distribution several concentric circless on the top board of described rectifying component.
Described a kind of water flow sensing unit, its special character is: described current stabilization hole is polygon shape,
Or the current stabilization hole of circle and polygonal current stabilization hole combination.
Described a kind of water flow sensing unit, its special character is: also comprise a rectifier, and rectifier is arranged on described rectifying component bottom.
A kind of water flow sensing unit of the utility model, owing to adopting such structure, current stabilization part makes uniform fluid flow pass through, keep entering water (flow) direction in magnet rotor support consistent, thus make driving magnet rotor water (flow) direction consistent, reach magnet rotor and operate steadily, input signal is stablized.
