Description

Multifunctional sealing gasket and filter element thereof

Technical Field

The utility model relates to a water purification filter equipment's accessory, especially a multi-functional sealed pad and filter core easy to assemble.

Background

The existing water circuit board generally comprises a front filter element seat, a rear filter element seat and an RO filter element seat, wherein the front filter element seat and the rear filter element seat comprise a tap water inlet, a front water outlet, a rear water inlet and a rear water outlet, the front water outlet is positioned in the center, and the tap water inlet, the rear water inlet and the rear water outlet are positioned on the equal-diameter circumference of the front water outlet; the RO filter core seat comprises a pure water outlet, a waste water outlet and an RO filter core water inlet, wherein the pure water outlet is positioned in the center of the RO filter core seat, and the waste water outlet and the RO filter core water inlet are positioned on the equal-diameter circumference of the pure water outlet. For the water outlet in the filter element seat, such as the front water outlet and the pure water outlet, in order to prevent them from leaking, the existing method is to provide two O-ring seals with small diameter on one side of the filter element seat, the two O-ring seals with small diameter correspond to both sides of the water outlet, and then respectively use one O-ring seal with large diameter on the corresponding filter element, for example, a O-ring seal with large diameter is provided on the front and rear filter elements, and a O-ring seal with large diameter is also provided on the RO filter element, then the front and rear filter elements and/or the RO filter element respectively use the O-ring seal with large diameter to cooperate with the O-ring seal with small diameter to achieve the sealing of the front water outlet and/or the pure water outlet.

In the installation process, the sealing ring is difficult to install in the sealing mode, and the sealing ring is easy to deviate in the use process, so that the risks of water leakage and water leakage are caused to a certain degree.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses to the society provide an installation easily, can not the multi-functional sealed pad of off tracking and filter core thereof.

The technical scheme of the utility model is that: the multifunctional sealing gasket is made of elastic materials, is suitable for being used on a water circuit board, and comprises a bottom plate, wherein the bottom plate is provided with a through hole, a first channel and a second channel which extend outwards are respectively arranged at two sides of the through hole, an annular body extends out of one side of the bottom plate along the outer edge of the bottom plate, a hanging edge parallel to the bottom plate extends outwards from the free end of the annular body, and two convex columns are arranged at one side of the bottom plate, which is far away from the annular body.

As an improvement to the present invention, the elastic material is silica gel or rubber.

The utility model also provides a filter core includes foretell multi-functional sealed pad.

The utility model discloses owing to with many external seal circle integrated design among the prior art, adopted the bottom plate is equipped with the through-hole the both sides of through-hole are equipped with the first passageway and the second passageway of outside extension respectively, follow the outside of bottom plate to extend the ring form in one side of bottom plate, the free end of ring form outwards extends and is on a parallel with the outstanding limit of bottom plate keep away from of bottom plate one side of ring form is equipped with the structure of two projection bodies, makes the utility model has the advantages of the installation is easy, can not the off tracking to and can not appear leaking and the phenomenon of crossing water.
