It opens or seals；The return unit 5 includes sealing return unit 51 and boiled water return unit 52；
The sealing part 4 has sealing position and boiled water position in ontology, when the sealing part 4 is located at sealing position,
The boiled water return unit 52 accumulates elastic reset power.When the sealing part 4 is located at boiled water position, the sealing return unit 51 is accumulated
Elastic reset power.
With further reference to Fig. 3-6, when sealing part 4 is located at sealing position, moving part is driven to move by handover operation part 2
It is dynamic so that the water in internal pressure chamber 41 is flowed out from opening 42 when opening 42 is opened, sealing part 4 by upward hydraulic pressure with
And the reset force effect of boiled water return unit 52, boiled water position is moved to from sealing position；
When sealing part 4 is located at boiled water position, drive moving part mobile by handover operation part 2, so that when opening
42 sealings, water flow are gathered in internal pressure chamber 41, and sealing part 4 is acted on by the reset force of sealing return unit 51, are moved from boiled water position
Dynamic water position to end.
A kind of above-mentioned water sealing structure can rely on the collective effect of boiled water return unit 52 and hydraulic pressure will in low hydraulic pressure
Water outlet is opened, and is not opened or cannot be fully opened in low pressure using guide's valve arrangement to overcome traditional water check valve
The problem of, guarantee the flow under low pressure.Likewise, water outlet is closed by sealing return unit 51, to overcome traditional
The problem of water check valve closes incessantly under low pressure.
As shown in Figs. 1-2, the specific structure of the present embodiment is described as follows: the moving part 3 is to be arranged along ontology 1 is axial
Switching shaft, the sealing part 4 is coaxially disposed with switching shaft, so that the switching shaft passes through the opening 42；Described first
Points 31 and second part 32 be arranged along the length direction of switching shaft, and the diameter of first part 31 is greater than second part 32.
In order to allow first part 31 that can seal the opening, in the present embodiment, a sealing is provided at the opening 42
Circle 421；The switching shaft move to first part 31 and 421 position of sealing ring it is corresponding when the first part 31 and sealing ring
421 fittings seal the opening 42；The switching shaft move to second part 32 and 421 position of sealing ring it is corresponding when described in
Sealing ring 421 is separated with second part 32 opens the opening 42.In this way by changing the diameter of different location on switching shaft,
Can simple realization switching shaft open or seal the purpose of the opening 42 when moving to different location.It is relatively simple for structure
It is ingenious.
The sealing part 4 includes upper piston 43 and lower piston 44；The upper piston 43, lower piston 44 are coaxially disposed, and
It is provided with through-hole respectively along axially penetrating through, in a part insertion upper piston 43 of the lower piston 44, so that 43 He of upper piston
The through-hole split of lower piston 44 forms the bit port that allows for supplying the switching shaft to pass through.
In order to realize the fixed installation of sealing ring 421, the through-hole wall of the upper piston 43 extends towards out a pair of of convex block
431, the sealing ring 421 is fixed between the lower surface of convex block 431 and the end face of lower piston 44.Since upper piston 43 is under
Piston 44 moves together, thus position of the sealing ring 421 in sealing part 4 be just fixed it is constant.
In the present embodiment, in order to realize the setting of internal pressure chamber 41, the sealing part 4 further includes a sealing cover 45, described close
Capping 45 is coaxially disposed with switching shaft, and is located at the top of the upper piston 43；The sealing cover 45 is fixed in ontology 1, is made
It obtains sealing cover 45 and the common split of upper piston 43 forms the internal pressure chamber 41.Sealing cover 45 remain stationary relative to ontology 1 it is motionless,
The through-hole passed through for switching shaft is set at the axle center of sealing cover 45.And through hole, which is provided with, remains sealing paste with switching shaft
The second sealing ring 451. closed ensures that water flow will not be flowed out from the gap between switching Zhu and through-hole in this way.
In order to fix the sealing cover 45 in ontology 1, the ontology 1 includes upper housing 13 and lower case 14, under described
Shell 14 has opening towards the side of upper housing 13, and the opening inner wall of the lower case 14 circumferentially extends circle gear
Side, the lower surface of the sealing cover 45 and rib contact, the lower end surface contact of upper surface and upper housing 13, such sealing cover 45
It is just clamped and fixed between upper housing 13 and lower case 14.The side wall of the lower case 14 is circumferentially spaced described in setting
Water inlet 11.
In addition, the water inlet in order to guarantee internal pressure chamber 41, the side of the upper piston 43 is normal equipped with being connected to internal pressure chamber 41
Opening 431.Furthermore, it is ensured that water flow can only flow into internal pressure chamber 41 from normally open 431, the side of the upper piston 43 be equipped with
The Y-shaped ring 432 of 1 inner wall of ontology fitting, the opening 42 of the Y-shaped ring 432 is towards the internal pressure chamber 41.
In order to realize sealing of the sealing part 4 to water outlet 12, the end face of the water outlet 12 extends towards to form circle gear
Side, when the sealing part 4 is located at the position Guan Shui, the end face of the lower piston 44 is bonded with the rib.Since water flow is from water inlet
It after mouth 11 flows into ontologies 1, is flowed out from the gap between 44 side of lower piston and ontology 1, therefore, the end face of lower piston 44
After the rib fitting of water outlet 12, water flow can not just be flowed out from water outlet 12, realize the function of sealing.
In addition, sealing return unit 51 and boiled water return unit 52 are respectively spring in the present embodiment, handover operation part 2 is button
The pressing switching mechanism constituted with ball point pen mechanism.Pressing switching mechanism belongs to conventional design in the prior art, so this reality
It applies in example and its specific structure is not described.Those skilled in the art can also adopt according to the enlightenment of the present embodiment
With other handover operation structures.
The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented
It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual
In the range of type covers.
