The device has threaded grooves. The first housing 1 has a disassembly and assembly assembly inside. During operation, the first housing 1 is configured with a pair of detachable connecting pipes 2 inside the first housing 1. A groove is opened on one side of the pair of connecting pipes 2. The first filter pipe 4 inside the first housing 1 is fixed in the first groove 3 opened on one side of the connecting pipe 2 by the disassembly and assembly assembly. The first filter pipe 4 and the second filter pipe 6 can perform double-layer filtration of the water source to ensure the purity of the water source. When it is necessary to disassemble the device, the first filter pipe 4 can be disassembled by simply using the disassembly and assembly assembly assembly. The threaded grooves opened in the pair of connecting rings 9 can connect the pair of connecting rings 9 to the inlet pipe and the outlet pipe. The first housing 1 and the second housing 8 can seal the device.

[0025] The disassembly and assembly assembly includes a first threaded sleeve 10 and a transmission unit; a pair of first threaded sleeves 10 are each sleeved on a first filter tube 4; a first connecting block 11 is fixedly connected to the outer circular wall of a pair of first threaded sleeves 10; a pair of first sliding grooves 12 are opened inside a pair of connecting tubes 2; a pair of first connecting blocks 11 are slidably connected to a pair of first sliding grooves 12 respectively; a pair of second sliding grooves 14 are opened at the top of the first filter tube 4; a pair of second connecting blocks 13 are fixedly connected to the bottom of a pair of first threaded sleeves 10 respectively; a pair of second connecting blocks 13 are slidably connected to a pair of second sliding grooves 14 respectively. During operation, by opening a pair of first sliding grooves 12 in a pair of connecting tubes 2, during disassembly, the transmission unit drives a pair of first threaded sleeves 10 to slide outward from a first groove 3 on one side of a pair of connecting tubes 2, so that the pair of connecting tubes 2 are no longer connected to the first threaded sleeves 10. When the first connecting block 11 slides out of the first sliding groove 12, the second connecting block 13 will enter the second sliding groove 14, ensuring that the first threaded sleeve 10 itself will not rotate.

[0026] The transmission unit includes a rotating ring 15; the rotating ring 15 is fixed to the first filter tube 4; second threaded sleeves 16 are fixed to both sides of the rotating ring 15; a pair of first threaded sleeves 10 are respectively threaded to the outer circular wall of the second threaded sleeves 16. During operation, the rotating ring 15 is fixed to the outer circular wall of the first filter tube 4, and the second threaded sleeves 16 are fixed to both sides of the rotating ring 15. During installation, the rotating ring 15 can be rotated to move the first threaded sleeves 10 and the second threaded sleeves 16 into the connecting tube 2, so that the first connecting block 11 is inserted into a pair of first sliding grooves 12, and one end of the first threaded sleeve 10 is connected to the interface of the first groove 3 inside the connecting tube 2, so that the water source flows into the first filter tube 4 and the second filter tube 6 for filtration. When disassembling the equipment, it is only necessary to reverse the rotating ring 15 to move the first external threaded sleeves on both sides outward at the same time, pull the first connecting block 11 out of the first sliding groove 12, and then remove the equipment from the first housing 1 as a whole to complete the complete disassembly of the equipment.

[0027] A T-shaped groove 17 is formed on one side of the first housing 1; a T-shaped block 18 is fixedly connected to one side of the second housing 8; the T-shaped block 18 is slidably connected in the T-shaped groove 17; an annular groove 19 is formed on one side of the first housing 1; a semi-ring 21 is fixedly connected to one side of the second housing 8; the semi-ring 21 is slidably connected to the annular groove 19. During operation, by forming a T-shaped groove 17 on one side of the first housing 1 and fixing a T-shaped block 18 to one side of the second housing 8, the second housing 8 is slidably connected to one side of the first housing 1, thus protecting and sealing the internal equipment. The sliding groove formed on one side of the first housing 1 and the semi-ring 21 fixedly connected to one side of the second housing 8 can increase the connection between the first housing 1 and the second housing 8, ensuring that they will not fall off during long-term use and affect the internal filter element. During installation, the second housing 8 can be first fitted onto the inlet or outlet pipe, then the internal equipment can be installed, and finally the first housing 1 and the second housing 8 can be connected.

[0028] Each pair of first threaded sleeves 10 is provided with a waterproof gasket 20 at one end. During operation, by providing a waterproof gasket 20 at one end of each pair of first threaded sleeves 10, water leakage can be prevented when water enters or exits the equipment.

[0029] A rubber pad is provided on the outer circular wall of the rotating ring 15. During operation, the rubber pad on the outer circular wall of the rotating ring can prevent the operator's hand from slipping and increase the friction on the surface of the rotating ring 15.

[0030] Working principle: A first housing 1 is constructed, inside which a pair of detachable connecting pipes 2 are installed. A groove is formed on one side of each connecting pipe 2. A first filter pipe 4 inside the first housing 1 is fixed within the first groove 3 on one side of the connecting pipe 2 using a disassembly assembly. The first filter pipe 4 and the second filter pipe 6 provide double-layer filtration of the water source, ensuring its purity. Disassembly of the equipment is achieved simply by using the disassembly assembly. Threaded grooves within a pair of connecting rings 9 allow connection to the inlet and outlet pipes. The first housing 1 and the second housing 8 seal the equipment. A pair of first sliding grooves 12 are provided inside each of the pipes 2. During disassembly, the transmission unit drives a pair of first threaded sleeves 10 to slide outward from the first groove 3 on one side of the pair of connecting pipes 2, so that the pair of connecting pipes 2 are no longer connected to the first threaded sleeves 10. When the first connecting block 11 slides out of the first sliding groove 12, the second connecting block 13 will enter the second sliding groove 14, ensuring that the first threaded sleeve 10 itself will not rotate. By fixing a rotating ring 15 to the outer circular wall of the first filter pipe 4, and fixing second threaded sleeves 16 to both sides of the rotating ring 15, during installation, the rotating ring 15 can be rotated to move the first threaded sleeve 10 and the second threaded sleeve 16 into the connecting pipe 2, so that the first connecting pipe 2 is no longer connected to the first threaded sleeve 10. Block 11 extends into the interior of a pair of first sliding grooves 12, connecting one end of the first threaded sleeve 10 to the interface of the first groove 3 inside the connecting pipe 2, allowing water to flow into the first filter pipe 4 and the second filter pipe 6 for filtration. When disassembling the equipment, simply reverse the rotating ring 15 to move the first external threaded sleeves on both sides outwards simultaneously, pulling the first connecting block 11 out of the first sliding groove 12. Then, remove the equipment from the first housing 1 as a whole to complete the disassembly. By opening a T-shaped groove 17 on one side of the first housing 1 and fixing a T-shaped block 18 to one side of the second housing 8, the second housing 8 is slidably connected to one side of the first housing 1, providing a protective seal for the internal equipment. The sliding groove on one side and the semi-ring 21 fixed to one side of the second housing 8 can increase the connection between the first housing 1 and the second housing 8, ensuring that they will not fall off during long-term use and affect the internal filter element. During installation, the second housing 8 can be first fitted onto the inlet or outlet pipe, then the internal equipment can be installed, and finally the first housing 1 and the second housing 8 can be connected. By setting a waterproof gasket 20 at one end of a pair of first threaded sleeves 10, water leakage can be prevented when water enters or exits. By setting a rubber pad on the outer circular wall of the rotating ring, the operator can rotate the ring 15 without slipping their hand and increase the friction of the rotating ring 15 surface.
