Closing, and the water remained in discharge cavity 20 is discharged by remaining pressure relief vent 11.
When it is implemented, since extruding force is not present, the part that elastic material 22 is shunk is gradually multiple when ice melting
Original, and the elastic resistor 21 on 11 surface of pressure relief vent is corresponded to inside watch core 10 also because of the thawing of ice cube, from newly setting back, so that
Pressure relief vent 11 is blocked again, be ensure that the consistency of 10 inner space size of watch core, be will not influence the stream of water flow in watch core 10
It is dynamic.
When it is implemented, avoid after ice melting, influenced by ice cube extruding by the design of elastic resistor 21, elasticity
Material 22 can generate deformation, and spatial form, size in watch core 10 is caused to change, to influence flow characteristics, further protect
The high-precision characteristic of water meter is demonstrate,proved.

When user's normal use water, water flow is respectively from the intake tunnel 310 that is preset in watch core outer box 300 and micro
Recirculation hole 330 enters impeller box 100；And when water is flowed into from intake tunnel 310, the pressure water part that is preset on intake tunnel 310
320 are jacked up under the action of water pressure, and water can smoothly be flowed into from intake tunnel 310；
When it is implemented, water flow is flow in water meter from water inlet, via watch core outer box 300 when user's just common water
300 side wall of intake tunnel 310 and watch core outer box on trace stream through-hole 330 enter impeller box 100, realize the metering of water flow；
Wherein, when water flow enters from intake tunnel 310, pressure water part 320 in the presence of hydraulic pressure, is no longer close to watch core outer box 300
Bottom, water flow can smoothly enter into inside impeller box 100.
When water flow is smaller, and water flow can not open the pressure entrance impeller box 100 of water part 320, water flow then passes through trace stream through-hole
330 flow into the corresponding water inlet of impeller box 100 slot, and forming larger hydraulic pressure makes impeller normal rotation.
When it is implemented, when water flow is smaller, so that it cannot when opening pressure water part 320, due to depositing for trace stream through-hole 330
It can then concentrate in, water flow from trace stream through-hole 330 and enter impeller box 100, since trace stream through-hole 330 is directly connected to impeller box
Therefore the water inlet slot of 100 middle setting so that micro water flow will form the larger hydraulic pressure of concentration, as shown in figure 11, realizes collection
Middle impact impeller, enables impeller normal rotation, avoids user using weep amount and carries out stolen water.
