Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purifier filter technology, and in particular to a quick-release water purifier filter structure. Background Technology
[0002] A water purifier, also known as a water filter or water purifier, is a device specifically designed to deeply filter and purify water according to specific water needs. In daily life, the water purifiers we usually refer to are small water purification devices suitable for home environments. Their core technology lies in the filter membrane within the filter cartridge, which is primarily based on three technologies: ultrafiltration membrane technology, RO (reverse osmosis) membrane technology, and nanofiltration membrane technology.
[0003] Typically, a vertical tube is installed in the filter cartridge and is inserted into the water outlet pipe on the filter cylinder. Due to the need for a seal between the vertical tube and the water outlet pipe, the insertion and removal of the vertical tube and the water outlet pipe are quite tight. Currently, when disassembling the filter cartridge, it is necessary to pinch the vertical tube and pull it out. Since the vertical tube is relatively thin and located inside the filter cylinder, it is difficult to exert force, making the operation more strenuous and inconvenient. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick-release water purifier filter element structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A quick-release water purifier filter element structure includes: a filter cartridge, the upper end of which is detachably connected to a cartridge cover, the lower end of which is provided with a water outlet pipe fixedly connected to the filter cartridge, and the upper end of the cartridge cover being provided with a water inlet pipe fixedly connected to the cartridge cover.
[0007] The filter element has a vertical tube running through its middle section. The lower part of the side wall of the vertical tube has a side hole. The upper end of the vertical tube has two notches. The side wall of the vertical tube near the lower end has two first annular grooves. Each first annular groove has a sealing ring inside. A sealing retaining ring is fixedly fitted onto the upper part of the side wall of the filter element.
[0008] A positioning mechanism is connected to the inner top of the cylinder cover, and the positioning mechanism cooperates with the sealing ring;
[0009] A connecting mechanism is connected to the water inlet pipe.
[0010] As a further improvement of this utility model, the cylinder cover is threaded onto the upper end of the filter cylinder.
[0011] As a further improvement of this utility model, the positioning mechanism includes a positioning ring, and two connecting rods are fixedly connected to the upper surface of the positioning ring. The end of the connecting rod away from the positioning ring is fixedly connected to the inner top wall of the cylinder cover.
[0012] As a further improvement of this utility model, the connecting mechanism includes a rotating ring, a second annular groove is provided on the side wall of the water inlet pipe, the rotating ring is located inside the second annular groove, and a U-shaped rod is fixedly connected to the lower surface of the rotating ring.
[0013] As a further improvement of this utility model, the connecting rod and the positioning ring are integrally formed.
[0014] As a further improvement of this utility model, the lower edge of the vertical tube is provided with a narrowed bevel.
[0015] The beneficial effects of this utility model are:
[0016] By setting a sealing ring and a positioning mechanism, after the filter element is installed inside the filter cartridge, it can fit against the inner wall of the filter cartridge through the sealing ring. Then, when the cartridge cover is connected to the filter cartridge, the positioning ring can press on the sealing ring, so that the sealing ring fits evenly against the inner wall of the filter cartridge in the circumference, effectively improving the sealing performance.
[0017] By setting a connecting mechanism and a notch, when the U-shaped rod is inserted into the notch, when it is necessary to remove the filter element from the filter cartridge, simply hold the cartridge cover and pull it outwards. The vertical tube and the filter element can then be pulled outwards by the U-shaped rod, which makes it easy to apply force and thus easy to remove the filter element.
[0018] This invention connects the vertical tube to the cylinder cover, making it easier to pull out the filter element, reducing effort during operation, and facilitating filter element replacement. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figures 1-7 A quick-release water purifier filter element structure includes a filter cartridge 1, a cap 2 detachably connected to the upper end of the filter cartridge 1, the cap 2 being threaded onto the upper end of the filter cartridge 1, an outlet pipe 4 fixedly connected to the filter cartridge 1 passing through the lower end of the filter cartridge 1, and an inlet pipe 3 fixedly connected to the cap 2 passing through the upper end of the cap 2.
[0029] The filter element 5 has a vertical tube 6 running through its middle. The lower edge of the vertical tube 6 has a narrowed bevel to facilitate insertion of the vertical tube 6 into the water outlet pipe 4. The lower part of the side wall of the vertical tube 6 has a side hole 11, and the upper end of the vertical tube 6 has two notches 10. The side wall of the vertical tube 6 near the lower end has two first annular grooves 7. Each first annular groove 7 has a sealing ring 8 inside. The upper part of the side wall of the filter element 5 is fixedly fitted with a sealing retaining ring 9. External water enters the filter cartridge 1 through the water inlet pipe 3 and is filtered by the filter element 5. The filtered water can enter the vertical tube 6 through the side hole 11 and then exit through the water outlet pipe 4.
[0030] The positioning mechanism is connected to the inner top of the cylinder cover 2, and the positioning mechanism cooperates with the sealing ring 9;
[0031] The connecting mechanism is connected to the water inlet pipe 3.
[0032] In this utility model, the positioning mechanism includes a positioning ring 13. Two connecting rods 12 are fixedly connected to the upper surface of the positioning ring 13. The end of the connecting rod 12 away from the positioning ring 13 is fixedly connected to the inner top wall of the cylinder cover 2. The connecting rod 12 and the positioning ring 13 are integrally formed. After the filter element 5 is installed inside the filter cylinder 1, it can fit against the inner wall of the filter cylinder 1 through the sealing ring 9. Then, when the cylinder cover 2 is connected to the filter cylinder 1, the positioning ring 13 can press on the sealing ring 9, so that the sealing ring 9 fits evenly against the inner wall of the filter cylinder 1 in the circumferential direction, effectively improving the sealing performance.
[0033] The connecting mechanism includes a rotating ring 15. A second annular groove 14 is provided on the side wall of the water inlet pipe 3. The rotating ring 15 is located inside the second annular groove 14. The rotation between the rotating ring 15 and the second annular groove 14 has a certain damping. A U-shaped rod 16 is fixedly connected to the lower surface of the rotating ring 15. The U-shaped rod 16 can be inserted into the notch 10.
[0034] When using this utility model, insert the lower end of the vertical pipe 6 into the water outlet pipe 4, then cover it with the cylinder cover 2, so that the U-shaped rod 16 is inserted into the notch 10. Then rotate the cylinder cover 2 so that the cylinder cover 2 is screwed onto the filter cylinder 1. Then the water inlet pipe 3 is sleeved on the upper end of the vertical pipe 6, so that both the upper and lower ends of the vertical pipe 6 can be positioned and fixed to prevent the vertical pipe 6 from tilting. When it is necessary to remove the filter element 5 from the filter cylinder 1, rotate the cylinder cover 2 in the opposite direction to loosen it, and then hold the cylinder cover 2 and pull it outward. Since the U-shaped rod 16 is inserted into the notch 10, the vertical pipe 6 and the filter element 5 can be pulled outward through the U-shaped rod 16, which is convenient for applying force and thus convenient for disassembling the filter element 5. Then separate the vertical pipe 6 from the U-shaped rod 16.
[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
