TECHNICAL FIELD

[0001] The present application relates to the field of filter cartridges, in particular to a one-way RO reverse osmosis membrane filter cartridge. BACKGROUND

[0002] A water purifier is generally a device for filtering water by physical means to filter out most of the impurity particles in the water to meet the standard for direct human consumption. The core structure of the water purifier is the filter cartridge. There are many types of filter cartridges, including a one-way RO reverse osmosis membrane filter cartridge that filters water through a one-way RO reverse osmosis membrane. The RO reverse osmosis membrane used is a high-tech material with excellent filtering effect.

[0003] In order to improve the filtering effect of the water purifier, the existing water purifier often connects multiple filter cartridges to filter different types of impurities in the water. However, when replacing the filter cartridges, they often need to be disassembled and installed one by one. The water purifier is usually installed in a relatively narrow area, making it inconvenient to operate, and thus needs to be improved. CONTENT OF THE INVENTION

[0007] By adopting the above technical solution, when the first sleeve ring and the second sleeve ring are rotated out of the fixing sleeve, an annular structure can be formed on the side of the fixing sleeve. The end of the first sleeve ring is provided with a bevel block. At this time, the bevel block abuts against the end of the second sleeve ring, thereby maintaining the annular state of the first sleeve ring and the second sleeve ring, and facilitating the connection and fixation with another filter cartridge.

[0008] Optionally, a limiting groove is arranged in the inner side of the fixing sleeve, and the first sleeve ring is rotatably connected between the limiting groove and the fixing sleeve.

[0009] By adopting the above technical solution, the maximum rotation angle of the first ring can be limited by the limiting groove, thereby ensuring the neat arrangement of the filter element when connected, which is convenient for installation.

[0010] Optionally, a release rod is provided on the fixing sleeve, and the diameter of the release rod is equal to the diameter of the insertion hole.

[0011] By adopting the above technical solution, when connecting the filter elements, after the user completes the fixation between the first ring and the second ring and the new filter element, the user needs to pull the release lever on the new filter element so that the release lever 205 is inserted into the socket on the second ring. At this time, the connected filter element cannot be rotated, which is convenient for subsequent connection and installation. In order to facilitate the disassembly of the connected filter elements, the user can press the release lever so that the release lever presses down the inclined block, thereby releasing the connection between the first ring and the second ring, and then disassembling.

[0012] Optionally, the release rod is slidably connected to the fixing sleeve, and a first spring is fixedly connected between the release rod and the fixing sleeve.

[0013] By adopting the above technical solution and adding a first spring to the release lever, the release lever can be provided with an automatic reset capability through the elastic force of the spring.

[0015] By adopting the above technical solution, the inflow and outflow of water can be guaranteed, so that the entire filtering system constitutes a complete fluidity.

[0016] Optionally, the water inlet and the water outlet are rotatably connected to a first rotary head and a second rotary head respectively, a third sealing gasket is in contact between the first rotary head and the water inlet, and a third sealing gasket is in contact between the second rotary head and the water outlet.

[0017] By adopting the above technical solution, the first screw head and the second screw head on the two connected filter elements are in a relative state, the threaded sleeve on the second screw head is slid and the first screw head and the second screw head are rotated at the same time, so that the end of the first screw head slides into the inner side of the threaded sleeve.

[0018] Optionally, the water inlet and the water outlet are both sleeved with a resistance pad, a third spring is fixedly connected between the resistance pad and the filter element, and the bottom ends of the first rotary head and the second rotary head respectively conflict with the corresponding resistance pads.

[0019] By adopting the above technical solution, the resistance pad maintains close resistance between the rotary head and the third sealing pad on the water inlet and outlet of the filter element through the pushing action of the third spring, thereby ensuring the sealing effect there.

[0020] Optionally, a second sealing gasket is fixedly connected to the end of the first rotary head, and a first sealing gasket is fixedly connected to the second rotary head.

[0021] By adopting the above technical solution, the connection between the first rotary head and the second rotary head is fixed, and the sealing of the connection can be ensured by the provision of the first sealing gasket and the second sealing gasket.

[0022] Optionally, a threaded sleeve is slidably connected to the second screw head, the inner side of the threaded sleeve is in conflict with the first sealing gasket, and the inner side of the threaded sleeve and the end of the first screw head are both threaded structures.

[0023] By adopting the above technical solution, the threaded sleeve on the second screw head is slid and the first screw head and the second screw head are rotated at the same time, so that the end of the first screw head slides into the inner side of the threaded sleeve.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When the first and second rings are unscrewed from between the fixing sleeve, an annular structure can be formed on the side of the fixing sleeve. A bevel block is provided at the end of the first ring. At this time, the bevel block will interfere with the end of the second ring, thereby maintaining the annular state of the first and second rings;

[0026] 2. To facilitate the connection and fixation with another filter element, the user can press the inclined surface block through the socket at the end of the second ring to contact the interference state. At this time, the first ring and the second ring can continue to rotate and expand each other. The user can now place the fixing sleeve of the other filter element between the first ring and the second ring. Simply unscrew the first and second rings of the other filter element, and the first and second rings of the first filter element can be placed inside the fixing sleeve of the second filter element, thereby completing the connection and fixation between the two filter elements.

[0027] 3. The end of the bevel block on the first ring is a bevel structure, so that the first ring and the second ring can be quickly connected, which is convenient for the subsequent installation of the filter element. BRIEF DESCRIPTION OF THE DRAWINGS
