Description
Technical field
The utility model belongs to consumer goods industries, is related to a kind of bouncing valve core.
Background technique
In daily life, a water outlet is often arranged in the bottom of sink, and water outlet is connected to sewer pipe, water outlet
One switch valve of place's setting, needs to close switch valve when ponding in the sink, will switch when needing for the water in sink to be discharged
Valve is opened.The valve that bounces is exactly one of common switch valve.Spring valve includes being connected to the valve body of bottom of gullet and being arranged in valve body
Interior bouncing valve core.
Existing bouncing valve core structure is as depicted in figs. 1 and 2, including spring shell, setting spring fuse in spring shell,
It is axially disposed on the lateral surface of spring fuse to have sliding slot, positioning screw, the tail of positioning screw are threaded on the shell that bounces
It is circumferentially fixed in spring shell that portion is inserted into sliding slot the fuse that makes to bounce.When spring fuse moves up and down in spring shell
When, positioning screw is slided in sliding slot, and positioning screw and sliding slot have guiding role.The lower end of spring fuse is provided with spring,
The upper end of spring is resisted against on spring fuse, and the lower end of spring is resisted against on spring shell, and pull rod hook is equipped in spring.Spring
It is additionally provided on the lateral surface of fuse lower end in heart-shaped sliding groove, the upper end of pull rod hook is hooked in sliding groove, under pull rod hook
End hook spring shell lower end and by be set in spring shell lower end on locking spring fix.
Spring shell is fixed in the valve body of spring valve, and button cover, button cover energy are also connected on the upper end for the fuse that bounces
Enough and water outlet, which is formed, to be sealed.When needing to close spring valve, downwards by spring fuse, spring fuse, which moves downward, makes pull rod hook
Upper end is hooked at the cavity of heart-shaped slot upper end, and after release, pull rod hook, which holds spring fuse, prevents to bounce fuse from rising, to make
Button cover seals up water outlet.When needing to open spring valve, still further below by spring fuse, the upper end of pull rod hook is from heart-shaped slot upper end
Cavity at deviate from, after release, under the action of the spring, spring fuse rise, the upper end of pull rod hook is hooked in the lower end of heart-shaped slot
Place, positioning screw are resisted against on the lower end cell wall of sliding slot the fuse lifting position that makes to bounce and fix, and button cover opens water outlet, sink
In water between valve body and bouncing valve core gap location outflow.
Due to the exposed outside in spring shell of positioning screw, the water in sink can directly contact positioning spiral shell when flowing out
Nail, be easy to cause the corrosion of positioning screw, causes the reduction of circumferentially fixed effect, influence the normal use of bouncing valve core.And
When water flows out, the sliding slot to bounce on fuse can stretch out spring shell, and the impurity in water is also easy to enter spring shell from sliding slot
The inside of body is used for a long time and will cause the spring Caton of fuse and stuck, also will affect the use of spring, bouncing valve core is made to fail
It cannot use.One positioning screw of unilateral setting of spring shell positions spiral shell after the fuse that bounces under the action of the spring rises
Nail is resisted against on the lower end cell wall of sliding slot, and the side for the fuse that bounces is by the unilateral downward pressure of positioning screw, such stress
Situation is easy to make fuse run-off the straight of bouncing, and is unfavorable for stablizing for bouncing valve core and uses.
