Problems solved by technology

[0002] The working principle of the pre-filter is physical screening, and the main intercepted objects are sediment, rust, algae and other large particles. The filter device is removed, and the built-in filter device is cleaned or replaced separately. At this time, because the water supply valve is closed, the water supply is interrupted, which causes great inconvenience to domestic water use.

Embodiment Construction

[0027] Such as Figure 1~5 Shown is Embodiment 1 of the present invention, a pre-filter for sustainable water supply with core removal, comprising a valve seat 100 with a water inlet 110 and a water outlet 120 and a filter bottle 200 inserted under the valve seat 100, the filter bottle 200 is provided with a filter cylinder 210; the filter cylinder 210 utilizes the principle of physical screening, and the main intercepted objects are large particles such as sediment, rust, and algae; the valve seat 100 is provided with a switching mechanism; the water inlet 110 communicates with the water inlet cavity 220 on the periphery of the filter cylinder 210 through the switching mechanism, and the inner cavity of the filter cylinder 210 communicates with the water outlet 120 through the switching mechanism to form a first waterway; the water inlet 100 is directly connected to the water outlet 120 through the switching mechanism. The communication forms the second waterway; the first wa...

Abstract

A pre-filter with a detachable filter core for un-interruptible water supply has a valve seat (100), a filter canister (200) and a valve member (300). The filter canister (200) is detachably attached to a bottom of the valve seat (100), and the valve member (300) is mounted inside the valve seat (100). The pre-filter has a filtering position and a bypass position selected by turning the valve member (300). When n the filtering position, incoming water from an inlet port of the pre-filter is directed to the filter canister (200) to remove sediment and impurities contained in the water. When in the bypass position, the incoming water is prevented from entering the filter canister (200) and directly passes through the valve member (300) and flows to an outlet port of the pre-filter so that the filter canister (200) can be cleaned and replaced without interrupting water supply.

Description

technical field [0001] The invention relates to a core-removing pre-filter for sustainable water supply. Background technique [0002] The working principle of the pre-filter is physical screening, and the main intercepted objects are sediment, rust, algae and other large particles. The filter device is removed, and the built-in filter device is washed or replaced separately. At this time, because the water supply valve is closed, the water supply is interrupted, which causes great inconvenience to domestic water use. Contents of the invention [0003] In view of this, the object of the present invention is to provide an easy-to-use pre-filter with core removal and sustainable water supply, which can effectively solve the inconvenience caused by water cut-off cleaning or core replacement. [0004] The present invention adopts the following schemes to realize: a pre-filter for sustainable water supply after removing the core, including a valve seat with a water inlet and a...
