[0003] Currently, most filter elements on the market are usually installed inside the filter bottle, and most filter bottles are threadedly connected to the inside of the water purifier. When the filter element needs to be replaced, the filter bottle must be disassembled first, and then the old filter element must be removed from the filter bottle and the new filter element must be placed inside the filter bottle, and then the filter bottle must be installed on the water dispenser.

[0004] The two ends of the common filter elements on the market are respectively the water inlet and the water outlet. During the installation of the filter bottle, the water inlet of the filter element and the water outlet of the water dispenser need to be connected together. However, the common filter elements on the market usually lack a stabilizing device. After the filter element is placed inside the filter bottle, it is easy to shake, and it is difficult to keep the filter element in a stable centered state. As a result, it is difficult to quickly connect the water inlet of the filter element and the water outlet of the water dispenser, which is not convenient for quick installation of the filter element.

[0026] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a deep filter mesh wound filter element, comprising a filter element body 1, with docking tubes 2 fixedly installed at both ends of the filter element body 1, and a positioning mechanism 3 for easy installation is provided on the filter element body 1. By setting the positioning mechanism 3, the filter element body 1 can be kept in a stable centered state inside the filter cartridge, so that the docking tube 2 on the filter element body 1 can be quickly docked with the water outlet of the water dispenser, and a protective mechanism 4 is provided inside the docking tube 2. By setting the protective mechanism 4, the docking tube 2 can be protected when the filter element body 1 is not put into use, so as to prevent impurities from invading the interior of the filter element body 1 through the docking tube 2.

[0027] The above-mentioned positioning mechanism 3 includes a swivel 31, a positioning rod 32, a limit rod 33, a slide rod 34, an inclined groove 35, a rubber block 36, and a torsion spring 37; the swivel 31 is rotatably connected to the outer wall of the filter element body 1, and the side wall of the swivel 31 is fixedly installed with a slide rod 34, the positioning rod 32 is hinged to the outer wall of the filter element body 1, and an inclined groove 35 is provided on the positioning rod 32. When the three groups of positioning rods 32 are fitted against the inner wall of the filter cartridge, the filter element body 1 can be kept stably centered inside the filter cartridge under the positioning action of the three groups of positioning rods 32, so that the docking pipe 2 on the filter element body 1 can be accurately docked with the water outlet of the water dispenser during the installation process of the filter cartridge, the outer wall of the slide rod 34 is fitted against the inner wall of the inclined groove 35, and the swivel 31 is rotated. During the rotation of the swivel ring 31, the sliding rod 34 will be driven to move in contact with the inner wall of the inclined groove 35. At the same time, the sliding rod 34 will squeeze the positioning rod 32, so that the three groups of positioning rods 32 will rotate synchronously on the outer wall of the filter element body 1. The limiting rod 33 is hinged to the inner wall of the swivel ring 31. The side wall of the limiting rod 33 is fixedly installed with a rubber block 36. The rubber block 36 is in contact with the outer wall of the filter element body 1. A torsion spring 37 is provided at the hinge of the limiting rod 33 and the swivel ring 31. When the limiting rod 33 is released, the elasticity of the torsion spring 37 can drive the limiting rod 33 to rotate and reset. At this time, the limiting rod 33 can drive the rubber block 36 to be close to the outer wall of the filter element body 1. The swivel ring 31 can be limited by the rubber block 36 and the limiting rod 33.

[0028] The above-mentioned protection mechanism 4 includes a rotating rod 41, a hollow rod 42, a baffle 43, a spiral groove 44, a slide plate 45, and a connecting rod 46; one end of the rotating rod 41 is rotatably connected to the inner wall of the docking tube 2, and the other end of the rotating rod 41 passes through the docking tube 2 and is fixedly installed with a hollow rod 42, and the outer wall of the rotating rod 41 is fixedly installed with a baffle 43. The baffle 43 on the outer wall of the rotating rod 41 can be used to block the docking tube 2 to prevent impurities from invading the interior of the filter element body 1 through the docking tube 2 when the filter element body 1 is not put into use. The rotating rod 41 is rotatably connected to the penetration point of the docking tube 2, and the rotation of the rotating rod 41 can drive the baffle 43 to rotate from a horizontal state to a vertical state. At this time, the baffle 43 will release the blockage of the docking tube 2 so that Water flows inside the docking pipe 2, and a spiral groove 44 is provided on the side wall of the swivel 31. A slide 45 is slidably connected to the outer wall of the docking pipe 2, and a connecting rod 46 is fixedly installed on the top of the slide 45. The outer wall of the connecting rod 46 is attached to the inner wall of the hollow rod 42. The connecting rod 46 drives the slide 45 to slide on the outer wall of the docking pipe 2. The slide 45 moves and pushes the hollow rod 42, so that the hollow rod 42 drives the rotating rod 41 to rotate on the inner wall of the docking pipe 2. The end of the connecting rod 46 away from the slide 45 is attached to the inner wall of the spiral groove 44. During the rotation of the swivel 31, the spiral groove 44 will squeeze the connecting rod 46, so that the connecting rod 46 drives the slide 45 to slide on the outer wall of the docking pipe 2.

[0029] Working principle: After the filter element is placed inside the filter cartridge, the limiting rod 33 is pressed to rotate on the inner wall of the swivel 31. At the same time, the limiting rod 33 will drive the rubber block 36 to separate from the filter element body 1 and compress the torsion spring 37. Then the swivel 31 is rotated. During the rotation of the swivel 31, the sliding rod 34 will be driven to move against the inner wall of the inclined groove 35. At the same time, the sliding rod 34 will squeeze the positioning rod 32, so that the three groups of positioning rods 32 will rotate synchronously on the outer wall of the filter element body 1 and gradually move away from the filter element body 1 until the three groups of positioning rods 32 are in contact with the inner wall of the filter cartridge. The rotation of the swivel 31 can be stopped. At this time, the limiting rod 33 is released again, and the elasticity of the torsion spring 37 can drive The limit rod 33 rotates and resets. At this time, the limit rod 33 can drive the rubber block 36 to fit tightly against the outer wall of the filter element body 1. The rubber block 36 cooperates with the limit rod 33 to limit the swivel 31. At the same time, the sliding rod 34 and the inclined groove 35 can limit the positioning rod 32, so that the positioning rod 32 can be stably fitted against the inner wall of the filter cartridge. At this time, under the positioning action of the three groups of positioning rods 32, the filter element body 1 can be kept in a stable centered state inside the filter cartridge, so that the docking pipe 2 on the filter element body 1 can be accurately docked with the water outlet of the water dispenser during the installation process, which is convenient for quick installation of the filter element body 1 and the filter cartridge.

[0030] The baffle 43 on the outer wall of the rotating rod 41 can be used to block the docking tube 2 to prevent impurities from invading the interior of the filter element body 1 through the docking tube 2 when the filter element body 1 is not in use. When the rotating ring 31 rotates to drive the sliding rod 34 to push the positioning rod 32 so that the positioning rod 32 fits against the inner wall of the filter cartridge, the spiral groove 44 on the side wall of the rotating ring 31 will squeeze the connecting rod 46, so that the connecting rod 46 drives the slide plate 45 to slide upward on the outer wall of the docking tube 2. At the same time, the connecting rod 46 will fit against the inner wall of the hollow rod 42 to move and push the hollow rod 42 upward, so that the hollow rod 42 drives the rotating rod 41 to rotate on the inner wall of the docking tube 2. At this time, the rotation of the docking tube 2 can drive the baffle 43 to rotate from a horizontal state to a vertical state. At this time, the baffle 43 will release the blockage of the docking tube 2 so that water can flow inside the docking tube 2.

[0031] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
