Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a household water purifier. Background Technology

[0002] Household water purifiers are drinking water devices that perform advanced treatment of tap water. They originated in Europe and America in the 1950s and mainly remove impurities from the water through physical filtration and chemical adsorption technologies.

[0003] To ensure water quality and filtration efficiency, existing household water purifiers require regular inspection and replacement of their internal filter cartridges. This process involves removing the filter bottle, replacing the filter cartridge, and then using a special wrench to reattach the filter bottle to the purifier. However, this cumbersome installation process is time-consuming and laborious, especially when replacing multiple filter cartridges simultaneously. It also hinders efficient replacement of multiple cartridges and reduces practicality. Therefore, it is necessary to design a new household water purifier to address these issues.

[0019] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0021] Example Please refer to Figures 1-6 This embodiment provides a household water purifier, including a water purifier body 1, multiple filter bottles 2 and multiple filter elements 3. The multiple filter bottles 2 are installed at equal intervals below the water purifier body 1. Each filter bottle 2 includes a bottle body 21 and a bottle bottom 22. The multiple bottle bodies 21 are threadedly connected to the water purifier body 1. A base frame 4 is fixedly connected between the bottom surfaces of the multiple bottle bottoms 22. An opening 41 is provided through the top surface of the base frame 4 near the left and right sides. A metal plate 5 is provided vertically on the bottom surface of the water purifier body 1 near the multiple filter bottles 2. The bottom surface of the metal plate 5 protrudes into the inner side of the base frame 4 through the opening 41. A quick-release bolt 6 is threadedly connected to the bottom surface of the metal plate 5. The output end of the quick-release bolt 6 faces upward and is fixedly connected to a protruding rod 61. The protruding rod 61 is cylindrical in design. An extrusion plate 7 is sleeved on the outside of the protruding rod 61. The extrusion plate 7 is made of aluminum alloy.

[0022] In this embodiment, the quick-release bolt 6 is rotated, causing it and the pressing plate 7 to move downwards simultaneously, with the top surface of the pressing plate 7 moving away from the inner top surface of the base frame 4. Then, the pressing plate 7 is rotated under pressure, aligning itself with the opening 41 on the base frame 4. The base frame 4 is then moved downwards, distancing itself from the metal plate 5, thus completing the simultaneous disassembly of multiple filter bottles 2. Finally, the multiple filter elements 3 requiring replacement are then processed. After replacement, the replaced... The filter element 3 is placed inside the bottle bottom 22 and inserted into the corresponding bottle body 21, so that the base frame 4 passes through the metal plate 5 again, bringing the bottle bottom 22 and the bottle body 21 closer together. Finally, the squeezing plate 7 is rotated again so that the squeezing plate 7 and the opening 41 are in a cross state. Finally, the squeezing plate 7 is restricted by both hands and the quick-release bolt 6 is pressed to ensure that the top surface of the squeezing plate 7 is in close contact with the inner top surface of the base frame 4, ensuring that the top surface of the bottle bottom 22 is in close contact with the bottom surface of the bottle body 21, and ensuring the tightness of the filter bottle 2.

[0023] As an optional implementation method, please refer to Figure 5The bottom of the bottle 22 has an integrally formed limiting rod 221 inside. The shape and structure of the limiting rod 221 are adapted to the filter element 3. The filter element 3 is sleeved on the outside of the limiting rod 221.

[0024] In this embodiment, the filter element 3 with a shape and structure that are compatible with each other is fitted inside the limiting rod 221, and then the base frame 4 is installed close to the multiple filter bottles 2. The filter element 3 inside the bottle bottom 22 is more stable, avoiding inconvenience caused by random shaking during the installation process.

[0025] As an optional implementation method, please refer to Figures 1-3 A gasket 8 is provided in a ring shape on the top surface of the bottle bottom 22 near the outer side, and the bottom surface of the bottle body 21 is in close contact with the top surface of the gasket 8.

[0026] In this embodiment, the gasket 8 is placed between the bottle body 21 and the bottle bottom 22, which makes the seal between the bottle body 21 and the bottle bottom 22 more ideal and avoids air leakage and water leakage.

[0027] As an optional implementation method, please refer to Figure 3 and Figure 6 The top surface of the bottle bottom 22 is integrally formed with a limiting frame 222 protruding into the inside of the bottle body 21. The diameter of the limiting frame 222 is adapted to the inner diameter of the bottle body 21.

[0028] In this embodiment, during installation, the limiting frame 222 is inserted into the inner side of the bottle body 21. The limiting frame 222 can effectively restrict the position between the bottle bottom 22 and the bottle body 21, making the stability between the bottle bottom 22 and the bottle body 21 more ideal during installation and making the installation operation more convenient.

[0029] As an optional implementation method, please refer to Figure 4 The bottom surface of the extrusion plate 7 is provided with multiple gripping rods 71, which protrude to the inside of the base frame 4.

[0030] In this embodiment, the operator applies pressure to the protruding gripper 71 to adjust the position of the extrusion plate 7, which is more convenient for the operator.

[0031] As an optional implementation method, please refer to Figures 1-3 The base frame 4 has openings 42 on both the left and right sides.

[0032] In this embodiment, the operator can apply pressure to the base frame 4 by gripping through the second opening 42, which makes it easier for the operator to perform a stable gripping operation on the base frame 4.

[0033] As an optional implementation method, please refer to Figures 1-2 Anti-slip pads 43 are provided on both the left and right sides of the bottom surface of the base frame 4.

[0034] In this embodiment, when the water purifier body 1 is placed in a certain place using the base frame 4, the water purifier contacts the contact surface through the anti-slip pad 43, making the stability of the water purifier more ideal and avoiding the phenomenon of easy slipping.

[0035] As an optional implementation method, please refer to Figure 1 The longitudinal diameter of the base frame 4 is larger than the longitudinal diameter of the water purifier body 1.

[0036] In this embodiment, the design of the longitudinal diameter of the base frame 4 makes the water purifier more stable when placed in a certain position by the base frame 4, preventing it from tipping over due to deviation of the center of gravity.

[0037] As an optional implementation method, please refer to Figure 1 The longitudinal diameter of opening 41 is larger than the longitudinal diameter of metal plate 5.

[0038] In this embodiment, the design of the diameter of the opening 41 makes the disassembly and assembly of the base frame 4 more convenient, avoiding the impact on the operator's disassembly and assembly of the base frame 4 due to an unreasonable relationship between the diameter of the metal plate 5 and the opening 41.

[0039] As an optional implementation method, please refer to Figure 4 The inner side of the extrusion plate 7 is provided with a rubber ring 9, and the inner side of the rubber ring 9 is in close contact with the outer surface of the protrusion 61.

[0040] In this embodiment, by applying pressure to flip the extrusion plate 7, the position of the extrusion plate 7 is restricted by the friction between the rubber ring 9 and the protrusion rod 61, making the stability of the extrusion plate 7 after pressure flipping more ideal, and preventing the extrusion plate 7 sleeved on the outside of the protrusion rod 61 from rotating arbitrarily and affecting the disassembly or assembly operation between the base frame 4 and the water purifier.
