Description

Filter core, filter core mounting structure and purifier of purifier

Technical Field

The utility model relates to a purifier, concretely relates to be the filter core mounting structure of purifier, still relate to a purifier.

Background

The water purifier is water treatment equipment for performing deep filtration and purification treatment on water quality according to the use requirement of the water. The water purifier can effectively filter out rust, sand, colloid, chemical agents for adsorbing residual chlorine, odor, abnormal color, pesticide and the like in water, and impurities such as bacteria, germs, toxins, heavy metals and the like in water. The filter element is a core component in the water purifier and is used for filtering water. When the filter core is in use, along with the extension of time, impurity in aquatic can block up the filter core, makes the filter capacity greatly reduced of filter core, needs to carry out periodic replacement to the filter core, consequently, the filter core in the present water purifier sets up to detachably usually and installs on the filter core base.

When the filter element is arranged on the filter element base, the water port on the filter element is communicated with the water flow channel inside the filter element base, the water to be filtered enters the filter element through the water flow channel and returns to the water flow channel after being filtered. When the filter core is pulled down from the filter core base, because the existence of the filter core inside and the filter core base residual water, water can spill from filter core and base, needs additionally to increase the cleaning work of residual water, causes the filter core to change inconveniently.

In order to solve the problems, a filter element water stopping structure is disclosed in the utility model chinese patent No. ZL201821775764.8 (publication No. CN 20933333322U), which includes a filter flask and a filter material in the filter flask, wherein a buckle is provided on the upper side of the filter flask, a rotatable water path switching plate is provided on the upper end of the filter flask, a water connection pipe is provided on the water path switching plate to communicate with the interior of the filter flask, the filter flask is relatively sealed, a water flow channel is provided at a position corresponding to the water connection pipe on the upper end, and a sealing ring is provided between the water flow channel and the lower side of the water path switching plate; through the design of the rivers passageway of rotatable water route switching board cooperation filter flask, when the filter core installation targets in place, during buckle on the filter flask and the draw-in groove joint on the filter core base, the rivers passageway aligns and makes rivers UNICOM, when the rotatory unblock of filter core, when the buckle on the filter flask deviates from the draw-in groove, rivers passageway dislocation, at this moment, the sealing washer switches the board with the water route and forms the water route sealed, plays the stagnant water effect.

Above-mentioned filter core stagnant water structure realizes that the water route of filter core and base switches on, the rotatory filter core of dismantling realizes the self-stopping of filter core and base through rotatory installation filter core to avoid filter core and base to leak after the separation.
