Swing filter-link device and water filtration equipment

Abstract

A swing-type filter cartridge connection device and its water filtration equipment are disclosed to prevent liquid leakage from a filter cartridge unit during swinging. The swing-type filter cartridge connection device includes a first connecting pipe and a fixing member. The first connecting pipe is inserted into an open end of one of the filter cartridge units and has a first stop portion. The first connecting pipe is rotatably connected to the fixing member, and the rotation axis of the first connecting pipe is perpendicular to the longitudinal direction of one of the filter cartridge unit structures. The fixing member includes a first perforation structure and a first baffle. The first connecting pipe passes through the first perforation structure to be inserted into the open end. The first baffle is disposed near an edge of an opening in the first perforation structure adjacent to the filter cartridge unit, and is used to block the first stop portion to restrict movement of the first connecting pipe relative to one of the filter cartridge units.

Claims

1. A swing-type filter element connection device for preventing liquid leakage from a filter element unit during swinging, the swing-type filter element connection device comprising: a first connecting pipe for insertion into an open end of the filter element unit, the first connecting pipe having a first stop portion; and a fixing member, the first connecting pipe being rotatably connected to the fixing member, and a rotation axis of the first connecting pipe being perpendicular to the longitudinal direction of a structure of the filter element unit, the fixing member comprising: a first perforation structure through which the first connecting pipe passes to be inserted into the open end; a first baffle disposed on an edge of the first perforation structure adjacent to a hole in the filter element unit for blocking one side of the first stop portion; and a first limiting member disposed on one side of the fixing member opposite to the filter element unit, the first limiting member being attached to the fixing member to block the other opposite side of the first stop portion, the first baffle cooperating with the first limiting member to restrict movement of the first connecting pipe relative to one of the filter element units.

2. The swing-type filter element connection device as claimed in claim 1, wherein the swing-type filter element connection device further comprises: a second connecting pipe for insertion into another open end of the filter element unit, the second connecting pipe having a second stop portion; and the fixing member further comprises: a second perforation structure through which the second connecting pipe passes to be inserted into the other open end; and a second baffle disposed on an edge of the second perforation structure adjacent to a hole of the filter element unit for blocking the second stop portion to restrict the movement of the second connecting pipe relative to the filter element unit.

3. The swing-type filter element connecting device as described in claim 2, wherein the fixing member includes a first section, a second section and a third section, the first section and the second section are symmetrically connected to the two opposite ends of the third section, the first perforation structure is disposed in the first section, the second perforation structure is disposed in the second section, and the first connecting pipe is aligned with the rotation axis of the first perforation structure with the rotation axis of the second connecting pipe in the second perforation structure.

4. The swing-type filter element connection device as described in claim 2, wherein the swing-type filter element connection device further includes a second limiting member, the first limiting member and the second limiting member are respectively disposed on both sides of the fixing member relative to the filter element unit; the second limiting member is attached to the fixing member, and the second baffle cooperates with the second limiting member to restrict the movement of the second connecting pipe relative to the filter element unit.

5. The swing-type filter element connection device as described in claim 1, wherein the first connecting pipe further has a first abutment top disposed next to the first stop portion for passing through the first perforation structure to abut against an outer surface of the filter element unit.

6. The swing-type filter element connecting device as described in claim 5, wherein the first limiting member has a first fastening portion that is inserted into a corresponding fastening groove of the fixing member to position the first limiting member on that side of the fixing member; the fixing member has a first release hole formed adjacent to one of the corresponding fastening grooves, the first release hole being for inserting an external element to push against the first fastening portion and separate from the corresponding fastening groove.

7. The swing-type filter element connection device as described in claim 1, wherein the swing-type filter element connection device further includes a bridging member that is detachably connected to the fixing member so that another filter element unit is connected in parallel to the filter element unit; the fixing member has a slot disposed in a section of the fixing member where the first perforation structure is located, and one end of the bridging member is detachably inserted into the slot to connect to the fixing member; wherein the bridging member includes a body, a pin end and a fixing end, the pin end and the fixing end being respectively disposed on two opposite sides of the body, the pin end being detachably inserted into the slot, and the fixing end being fixed to the side of the other filter element unit opposite to the filter element unit.

8. The swing-type filter element connection device as claimed in claim 7, wherein the fixed end includes a third perforation structure and a third baffle, the third perforation structure allowing another connecting pipe to pass through, and the third baffle blocking the other connecting pipe to restrict the movement of the other connecting pipe relative to one of the other filter element units.

9. The swing-type filter element connection device as claimed in claim 7, wherein the fixing member further has a second release hole formed at a position adjacent to the slot, the second release hole being for inserting an external element to push against the pin end and separate from the slot.

10. A water filtration device comprising: a filter element unit; and a filter element connection device as described in any one of claims 1-9.
