Description
Technical field
The utility model is specifically related to a kind of filter core water-stop structure.
Background technique
The seal water structure of filter core is much sealed using mandril, and mandril sealing needs to use spring, and spring is long-term in water
Being easily used to failure causes water shutoff bad.Also one is turntable sealings is filtered although which does not use spring
The limitation of core space is larger, principle be by above and below turntable hole location to just or being staggered and realize water flowing and cut off the water supply.
If water flowing is more, space is smaller, can make which angle no matter turntable go to, and can all not have sealing effect
Problem.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of effective sealing work of energy implementation
Filter core water-stop structure.
A kind of filter core water-stop structure of the utility model description, including filter core lid, wherein filter core is covered with cavity, in cavity
Equipped with the turntable that can be rotated along cavity, at least three connecting holes are equipped at the bottom surface of cavity, turntable is equipped at least three turntables
Through-hole, turntable through-hole overlap with connecting hole and implement connected state or turntable through-hole mutually staggers with connecting hole and implements to break
Stream mode, for turntable through-hole in non-circular, connecting hole is rounded.
Specific further, the cavity, which is equipped with, is locked in the pressure ring in cavity for turntable.
Specific further the outer surface of the filter core lid is equipped with positioning seat, and positioning seat is equipped with recess, and the exterior rim of pressure ring is set
There is pressure ring protrusion, pressure ring protrusion is placed in recess.
Specific further, the top of the turntable is equipped with positioning convex platform, and positioning convex platform peaks at the bottom surface of pressure ring.
Specific further, the turntable through-hole is equipped with gasket ring.
Specific further, the connecting hole is equipped with sealing ring.
Specific further, the filter core lid is connected with filter element shell.
The beneficial effects of the utility model are: this structure by position of the rotation turntable in cavity, make turntable through-hole with
Connecting hole overlaps and implements connected state or turntable through-hole and mutually stagger with connecting hole and implement disconnection state, plays effectively
Sealing function.

Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
As shown in Figures 1 to 4, a kind of filter core water-stop structure of the utility model description, including filter core lid 1, wherein filter core
Lid 1 is equipped with cavity 103, and the turntable 3 that can be rotated along cavity 103 is equipped in cavity 103, is equipped at least at the bottom surface of cavity 103
Three connecting holes 104, turntable 3 are equipped at least three turntable through-holes 301, and turntable through-hole 301 and connecting hole 104 overlap and reality
It applies connected state or turntable through-hole 301 and connecting hole 104 mutually staggers and implements disconnection state.This structure passes through rotation turntable 3
Position in cavity 103 makes turntable through-hole 301 and connecting hole 104 overlap and implement connected state；It needs to prevent filter core
When lid 1 leaks, 3 position of turntable is rotated again, and turntable through-hole 301 and connecting hole 104 is made to mutually stagger and implement disconnection state,
When turntable 301 misplaces, preferable sealing function is played.The filter core lid 1 is connected with filter element shell 6, the effectively cutting filter core of turntable 301
Water route in shell 6.In addition, being also equipped with filter core in filter element shell 6, the water flowed through is effectively filtered；Its turntable through-hole
301 in non-circular, effectively increases the aperture of through-hole 301, occurs error between assembly, pass through non-circular turntable through-hole 301
Overcome the presence of error.
Cavity 103 described in the utility model, which is equipped with, is locked in the pressure ring 2 in cavity 103 for turntable 3, makes turntable 3 and filter
Core cap 1 is mutually fitted close；The outer surface of the filter core lid 1 is equipped with positioning seat 101, and positioning seat 101 is equipped with recess 102, pressure ring 2
Exterior rim be equipped with pressure ring protrusion 201, pressure ring protrusion 201 is placed in recess 102, prevents pressure ring 2 from will shifting, further strong
Change and be fitted close between turntable 3 and filter core lid 1, is further reduced leakage chance；The top of the turntable 3 is equipped with positioning convex platform
302, positioning convex platform 302 peaks at the bottom surface of pressure ring 2, limitation 3 axial direction of turntable displacement.
Turntable through-hole described in the utility model is equipped with gasket ring 4.The connecting hole 104 is equipped with sealing ring 5, wherein gasket ring
4 and the further lift-off seal of sealing ring 5, it avoids leaking in connection.In addition, the turntable through-hole 301 is in non-circular
