Description

A kind of purifier with double water stopping functions

Technical field

The utility model relates to purifier field more particularly to a kind of purifiers with double water stopping functions.

Background technique

As the improvement of people's living standards, purifier is increasingly being application, it is miscellaneous in water resource to filter Matter.Purifier in use for some time, needs in time to replace filter core, to guarantee to be discharged quality, prevents secondary pollution.

Existing purifier generallys use filter core is linked into plate of water route after, make water inlet water route and the filter core of plate of water route Water inlet is connected, and the water outlet water route of plate of water route is connected with the water outlet of filter core, so that water flow flows through after filter core is filtered Outflow.Double water stopping functions refer to that when dismantling filter core, filter core and plate of water route realize hermetic seal function simultaneously.Double stop is realized at present The traditional approach of water function are as follows: pressed water shutoff cap come sealing by spring in filter core；Plate of water route is then to rotate to filter by manpower It drives rotor to rotate certain degree simultaneously when core, realizes the through-hole mutual dislocation on through-hole and plate of water route on rotor only Water function.

But there are still following defects in actual use for above structure: (1) by driving rotor to turn after then passing through rotation Dynamic dislocation is to realize sealing, if therefore being that can not be realized by rotating in the center point of rotor and plate of water route setting through-hole Through-hole dislocation, cause existing purifier water route can not be set in the center point of filter core, such structure will lead to can not Sealing；(2) purifier due to the above reasons, in current industry avoids that water route is arranged in the center point of filter core, can lead in this way Cause needs to increase the diameter dimension of rotor, just can guarantee that the hole after filter core rotates in plate of water route and rotor can be staggered completely, real Existing sealing, therefore obtained filter core occupied space is larger；Some purifiers are by will be on the through-hole or rotor in plate of water route Through-hole is arranged to trapezoidal hole to solve the above problems, but can correspondingly aperture be made to reduce, to affect net water flux, increase The problems such as water flow noise.
