Wherein, it is provided with flowmeter in joint shell 300；This flowmeter is included positioned at joint shell 300 delivery port 303
Interior impeller 306 assembly, Hall element 308 and circuit board 309；Described impeller 306 assembly includes impeller 306 and magnet 307,
Hall element 308 carries out real-time detection thus calculating the row of impeller 306 to magnet 307 position on impeller 306 blade 311
Amount, calculates the flow of liquid then.
Impeller 306 includes central rotating shaft 310, and rotating shaft 310 quartering is provided with four blades 311.Described magnet 307 is pacified
It is loaded in the blade 311 on described impeller 306, two magnet 307 are respectively arranged on two blades 311 being generally aligned in the same plane, and make
This two blade 311 rotation 180 degree is to calculate a flux unit, and this flux unit is counted according to the quantity of impeller 306 blade 311
Calculate；Described Hall element 308 and circuit board 309 are electrically connected with, and circuit board 309 is connected to wire and is connected power taking with power supply.Consider
To the initial alignment problem of magnet 307, because magnet 307 is than impeller 306 weight of plastic cement, so the work in magnet 307 weight
With under, do not have flow of fluid interference in the case of, the blade 311 with magnet 307 can automatically reset in Hall element 308
Just beneath.
It is provided with the leaf of connection joint shell 300 inner chamber 302 and delivery port 303 at described joint shell 300 delivery port 303
Wheel mounting groove 316, impeller 306 can be installed on to rotation in this impeller mounting groove 316；Open top in impeller mounting groove 316
It is provided with cover 314 to be covered, described Hall element 308 and circuit board 309 are provided with cover 314.
In described impeller 306, two blades 311 symmetric about the axis are provided with the cavity 312 of connection, and magnet 307 is inserted in
In this cavity 312, magnet 307 is holistic magnet 307 herein, and the free end of blade 311 is provided with the opening of cavity 312,
Magnet 307 inserts from opening.It is contemplated that the installation to magnet 307, the thickness of this cavity 312 is arranged must be than magnet 307
Thickness big, and the cavity wall in described cavity 312 arranges the raised line 313 of magnet 307 described in limited location that is to say, that magnetic
The surrounding of iron 307 by some raised lines 313 spacing in cavity 312, and be not directly contacted with cavity 312 inwall.
The inwall of described impeller mounting groove 316 is provided with symmetrical breach 318, and rotating shaft 310 end of described impeller 306 sets
It is placed in this breach 318；The bottom surface of described cover 314 is provided with the gag lever post 319 matching with described breach 318, gag lever post
The both ends accommodating impeller 306 rotating shaft 310 are left, so that impeller 306 can be turned between the bottom of 319 end and breach 318
Dynamic.
The both sides of described cover 314 are provided with fixture block 315, and described joint shell 300 is provided with and is matched with described fixture block 315
The snap ring 317 closing, the top surface of described cover 314 is provided with the storage tank of accommodating described Hall element 308 and circuit board 309
322.
Connected entrance 320 between described inner chamber 302 and impeller mounting groove 316 is less than described impeller 306 top half or height
In the latter half of described impeller 306, in general can be using the way less than impeller 306 the latter half, because fluid is also
Ponderable, if flowing directly into top half to flow out delivery port 303 it may appear that because of fluid weight thus causing impeller 306
Rotate unstable problem.Purpose is the upper half allowing and can only acting on impeller 306 when the liquid that inner chamber 302 flows out flows out
Partial blade 311 or the blade 311 of the latter half, that is, counter clockwise direction or problem rotationally clockwise, prevent
Connected entrance 320 spans top half and the latter half, so that liquid is flowed and does not have rule, is likely to result in impeller 306 not regularly
Rotate.
The passage 321 being connected between described inner chamber 302 and impeller mounting groove 316 is from inner chamber 302 toward impeller mounting groove 316
Become narrow gradually.According to hydromechanical bernoulli principle, in the passage 321 through narrowing from the width, flow velocity can gradually become fluid
Greatly.So in order to want fluid that impeller 306 can be promoted exactly to be rotated according to default direction, need fluid is carried out to add
Speed, when fluid from inner chamber 302 through this passage 321 flow out connected entrance 320 when, speed accelerate, due to connected entrance 320 direction
Set, then the fluid of acceleration will rapidly rush at the ad-hoc location of impeller 306 so as to rotate according to rule.
Operation principle of the present utility model: the water inlet 301 of water tank joint 3 is connected with water tank 1, delivery port 303 passes through water
Pipe is connected with water pump 2.When opening water pump 2, the liquid in water tank 1 due to the effect of water pump 2 suction, through water tank joint 3 to
Water pump 2 flows.When liquid is through water tank joint 3, enter impeller peace from water inlet 301 through inner chamber 302, connected entrance 320
In tankage 316, fluid rapidly flows toward impeller 306, so that impeller 306 is rotated according to specific direction.While starting water pump 2,
Also flowmeter can be started, namely start-up circuit plate 309 and Hall element 308, Hall element 308 starts to magnet 307
Position carries out real-time detection, that is, according to magnet 307 apart from Hall element 308 distance come output pulse signal through circuit
Plate 309 exports to pc, and it is (permissible according to the setting of magnet 307 and impeller 306 that impeller 306 rotates one flux unit of 180 degree calculating
Change), thus calculating the flow of fluid.
Above embodiment simply indicates that rather than limits the utility model, thus all according to the utility model patent application
Equivalence changes or modification that method described in scope is done, are all included in the utility model patent claim.
