[0025] With reference to the drawings of the specification, a composite filter element water-stop structure comprises a matching water-passing joint 10 and a filter bottle 20, wherein the water-passing joint is fixedly connected to the filter element seat 30, and the filter bottle is detachably connected to the filter element seat. The filter bottle is installed and removed from the water-passing joint by rotating. The structure also comprises a first rotating member 40 disposed between the filter element seat and the water-passing joint, wherein the first rotating member and the water-passing joint are end-face sealed via a first sealing ring 11, and the first rotating member can be rotated relative to the water-passing joint to achieve communication or staggering of the water outlet of the first rotating member with the water outlet of the water-passing joint; and a second rotating member 50 is further comprised, wherein the second rotating member and the filter bottle are end-face sealed via a second sealing ring 21, and the filter bottle can be rotated relative to the second rotating member to achieve communication or staggering of the water outlet of the second rotating member with the water outlet of the filter bottle. When the filter bottle is installed, Each water outlet (except the middle one) is connected. When the filter bottle needs to be disassembled, each water outlet (except the middle one) is staggered, and water no longer flows; the first rotating member and the second rotating member can rotate synchronously, and the first rotating member and the second rotating member can be separated when the filter element is disassembled. The water outlet of the first rotating member is connected to the water outlet of the second rotating member. In a preferred embodiment, the water outlets of these two components can remain in a connected state regardless of whether the filter element is in a disassembled or installed state. The rotation of the filter bottle relative to the water outlet joint can separate the second rotating member from the first rotating member, that is, the filter bottle and the water outlet joint are separated, completing the disassembly of the filter bottle. The second rotating member and the filter bottle can rotate axially relative to each other, but can move axially synchronously. The water outlet joint and the first rotating member are the same. They can rotate axially relative to each other, but can move axially synchronously.

[0028] Furthermore, at least two lugs 22 are provided on the peripheral side of the filter bottle, and a slide groove 31 adapted to the lug is provided on the inner periphery of the filter element seat. The rotation of the filter bottle relative to the filter element seat or the water inlet joint enables the lug to move in the slide groove, thereby completing the installation and removal movement of the filter bottle relative to the valve core seat, and also realizing the limitation of the rotation of the filter bottle, which is similar to the prior art and will not be elaborated again.

[0029] In order to achieve a better sealing effect, the water joint is provided with a first sink groove 12 on the first rotating part, and the first sealing ring can be set in the first sink groove; the filter bottle is provided with a second sink groove 23 on the second rotating part, and the second sealing ring can be set in the second sink groove.

[0030] In a preferred embodiment, the water outlet of the filter bottle includes a pure water outlet 24, which can be coaxially arranged with the axis of rotation of the filter element, and the other water outlets of the filter bottle are distributed on the peripheral side of the pure water outlet; the water outlet of the first rotating part includes a first pure water outlet 42, and the other water outlets of the first rotating part are distributed on the peripheral side of the first pure water outlet; the water outlet of the second rotating part includes a second pure water outlet 52, and the other water outlets of the second rotating part are distributed on the peripheral side of the second pure water outlet; the water outlet of the water joint includes a pure water outlet 13, and the other water outlets of the water joint are distributed on the peripheral side of the pure water outlet; the pure water outlet is connected with the first pure water outlet, the second pure water outlet, and the pure water outlet, and are coaxially arranged.

[0031] Preferably, the filter bottle is provided with three or four water inlets, and the number of water inlets of the first rotating member, the second rotating member, and the water connector matches the number of water inlets of the filter bottle. The embodiment depicted in the figure has four water inlets, which can be configured as two water inlets and two water outlets. Alternatively, there can be three water inlets, which can be configured as one for raw water inlet, one for wastewater outlet, and one for purified water outlet.

[0032] Furthermore, a first check valve 43 is provided at the first pure water outlet. The first check valve can be in a flow-open state when water flows out of the pure water outlet. A second check valve 25 is provided at the pure water outlet. The second check valve can be in a flow-open state after the filter element and the water outlet connector are installed. This ensures that the water outlet located in the middle (will not be staggered) will not leak. A push rod 44 is provided at the first pure water outlet. After the filter element and the water outlet connector are installed, the push rod can push open the second check valve to put it in a flow-open state. After the filter element is detached from the water outlet connector, the push rod can detach from the second check valve, and the second check valve is in a flow-closed state.

[0033] In use, second protrusions 53 are provided at intervals on the outer periphery of the second rotating member, and second protrusions 26 are provided on the filter element. A second chute 54 is formed between two adjacent second protrusions. The second protrusion can move in the second chute.

In this way, the water outlet of the filter bottle can be staggered with the water outlet of the second rotating member, and the water flow in the filter bottle will not flow out. When the second protrusion abuts and cooperates with the second protrusion, the filter element can drive the second rotating member to rotate synchronously, so that the filter bottle can drive the first rotating member. , the second rotating member rotates, while the water outlet joint does not move, so that the water outlet of the water outlet joint is staggered with the water outlet of the first rotating member, and water from the water outlet joint does not flow out; and / or: first protrusions 45 are arranged at intervals on the outer periphery of the first rotating member, and first bosses 14 are arranged on the water outlet joint, and a first slide groove 46 is formed between two adjacent first protrusions, and the first boss can move in the first slide groove, which can limit the rotation angle of the second rotating member, ensuring that the rotation angle can ensure the staggering of some water outlets, preventing the angle from rotating too much, so that the water outlets become connected again.

[0034] More specifically, the present invention is as follows: the second rotating member is connected to the filter bottle via a second sealing ring, and the outer side of the second sealing ring has a semicircular arc structure. When the filter element is removed, the second rotating member and the filter bottle rotate a certain angle, and the outer semicircular arc sealing structure can close the outer water channel (which can have three locations), and the middle water channel (the middle one is the pure water channel) is stopped by the second check valve, so that the water inside the filter element will not flow out. The first rotating member is also connected to the water flow joint via a first sealing ring, and the outer side of the first sealing ring has a semicircular arc structure. When the filter element is removed, the first rotating member and the water flow joint rotate a certain angle, and the outer semicircular arc sealing structure can close the three outer water channels, and the middle pure water channel is stopped by the first check valve, so that the water inside the machine will not flow out. The passage direction of the first check valve is the direction of water flow, and the passage direction of the second check valve is against the direction of water flow.
