Abstract

The present disclosure provides a filter adapter and a filter system, and further provides a specific filter installation method, which can achieve multiple guarantees to prevent liquid leakage during the disassembly and assembly of a filter. The filter adapter is configured to connect a connector base and a filter, and includes an adapter body, wherein the adapter body is provided with an accommodating cavity for accommodating a head of the filter, at least two shut-off valve passages are provided in the accommodating cavity, and at least two columnar shut-off valves configured to connect a fluid passage of the filter with a fluid passage of the connector base, wherein the at least two columnar shut-off valves axially move within the shut-off valve passages and are restricted from rotating.

Dependent claims

A filter adapter, configured to connect a connector base and a filter, comprising:

an adapter body, which is provided with an accommodating cavity for accommodating a head of the filter, wherein the accommodating cavity is provided with at least two shut-off valve passages;
and
at least two columnar shut-off valves, configured to connect a fluid passage of the filter with a fluid passage of the connector base, wherein the at least two columnar shut-off valves axially move within the shut-off valve passages and are restricted from rotating;
wherein a locking member is disposed on the adapter body and configured to form a locking connection with the connector base;
the locking member is provided with a linkage member cooperating with the filter;
and the linkage member converts rotational motion of the filter to drive the locking member to lock with the connector base;
and
wherein the accommodating cavity is configured to allow a diverter switch at the head of the filter to pass therethrough, and the linkage member converts rotational motion of the diverter switch to drive the locking member to lock with the connector base.

5 more elements

A filter system comprising a filter, wherein the filter comprises a bottle body, filter cartridges accommodated in the bottle body, and an end cover configured to seal the bottle body, wherein the filter is provided with a cylindrical protruding portion extending forward, and a second water inlet and a second water outlet are provided circumferentially on the protruding portion;

and
wherein the filter system further comprises a connector base configured to connect to an integrated waterway and a filter adapter configured to connect the connector base and the filter, wherein the filter adapter comprises an adapter body and at least two columnar shut-off valves;
the adapter body is provided with an accommodating cavity for accommodating a head of the filter, and the accommodating cavity is provided with at least two shut-off valve passages;
the columnar shut-off valves move axially within the shut-off valve passages and are restricted from rotating, and the columnar shut-off valves are configured to connect a fluid passage of the filter with a fluid passage of the connector base;
a first water inlet and a first water outlet are provided on radial side walls of the two columnar shut-off valves, respectively;
the filter moves axially while rotating, and axial movement of the filter drives the two columnar shut-off valves to move axially within the accommodating cavity;
and when the filter rotates to a preset position, the first water inlet and the first water outlet of the two columnar shut-off valves are driven to be in communication with the second water inlet and the second water outlet of the protruding portion, respectively;
and
wherein the connector base is provided with a first shut-off valve at least in a water inlet passage;
the filter axially moves while rotating, and axial movement of the filter drives the two columnar shut-off valves to axially move within the accommodating cavity;
and when the filter rotates to the preset position, water passages of the two columnar shut-off valves are driven to be in communication with the second water inlet and the second water outlet of the protruding portion, respectively, and the columnar shut-off valves engage with the first shut-off valves and move and open the first shut-off valves, wherein each of the first shut-off valves comprises a valve body and a spring member configured to enable the valve body to close a first water inlet passage or a first water outlet passage, and when the adapter and the connector base are assembled in position, the columnar shut-off valves move axially to push the valve body axially to open the first water inlet passage or the first water outlet passage.
