[0022] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the drawings.

[0023] Please refer to Figures 1-4, the present utility model proposes a water purifier filter bottle assembly, including an upper filter bottle 1, a filter bottle cap 2 is sleeved on the top end of the upper filter bottle 1, a ring-shaped flange 3 is fixedly installed on the surface of the upper filter bottle 1, and a reinforcing rib 9 is fixedly installed on the bottom surface of the ring-shaped flange 3. The ring-shaped flange 3 and the reinforcing rib 9 can be fixed by welding or riveting. The welding method ensures the firmness of the assembly and the stability during long-term use, while the riveting method has the characteristics of being easy to disassemble and repair. The reinforcing ribs 9 are arranged in a circular pattern on the bottom surface of the ring-shaped flange 3. Through this arrangement, the structural strength of the filter bottle assembly is enhanced, enabling it to maintain stability under the action of high-pressure water flow. A lower filter bottle 4 is slidably connected to the surface of the upper filter bottle 1. The lower filter bottle 4 is slidably connected to the upper filter bottle 1 through a guiding chute. The guiding chute can be made of stainless steel or wear-resistant plastic. Stainless steel has good corrosion resistance, while wear-resistant plastic can reduce the friction during the sliding process, thus ensuring the smoothness of the sliding connection and the durability during long-term use. A sealing ring 16 is fixedly installed inside the lower filter bottle 4. The sealing ring 16 can be made of silicone or rubber. Both of these materials have good sealing performance. Among them, silicone can withstand high temperatures, and rubber has good elasticity and wear resistance, which can effectively prevent water leakage.

[0024] A threaded rod 5 is rotatably connected to the bottom surface of the ring-shaped flange 3. The threaded rod 5 is rotatably connected to the ring-shaped flange 3 through a ball bearing or a rotary joint. The ball bearing can provide low-friction and high-precision rotational movement, while the rotary joint can adapt to connection requirements at different angles, ensuring the smooth operation of the threaded rod 5 when being screwed. A screwing cap 10 is fixedly installed at the bottom end of the threaded rod 5. The screwing cap 10 is of a hexagonal structure. The screwing cap 10 can be made of aluminum alloy or stainless steel. Aluminum alloy has the characteristics of being light and strong, while stainless steel can maintain good corrosion resistance and durability in a humid environment. A sliding rod 6 is fixedly installed on the bottom surface of the ring-shaped flange 3. The sliding rod 6 is connected to the ring-shaped flange 3 through a guiding slide rail. This guiding slide rail can ensure the smooth movement of the sliding rod 6 and at the same time increase the overall strength and durability of the assembly. Side block A 7 and side block B 8 are fixedly installed on the surface of the lower filter bottle 4. A thread is provided inside the side block A 7, and the thread meshes with the threaded rod 5. The meshing design of the thread enables the side block A 7 to move along the thread direction when the threaded rod 5 rotates, thereby driving the upper filter bottle 1 and the lower filter bottle 4 to slide relative to each other, adjusting the height of the filter bottle to adapt to different lengths of filter elements. The sliding rod 6 is slidably connected to the side block B 8, ensuring the stability of the entire adjustment process.

[0025] A jacking mechanism is provided at the bottom end of the lower filter bottle 4. The jacking mechanism includes a vertical rod 11, which is slidably connected to the lower filter bottle 4. The vertical rod 11 can be connected to the lower filter bottle 4 through a guiding sleeve or a guiding slide rail to ensure smooth up and down movement of the vertical rod 11. The vertical rod 11 penetrates through the bottom end of the lower filter bottle 4, and a bottom block 12 is fixedly installed at the bottom end of the vertical rod 11. The bottom block 12 is made of high-strength plastic or stainless steel. This material selection can ensure that there is no wear or deformation during long-term use. A cross plate 13 and a longitudinal plate 14 are fixedly installed at the top end of the vertical rod 11. The cross plate 13 and the longitudinal plate 14 can be made of aluminum alloy or stainless steel. Aluminum alloy material has the characteristics of being light and strong, while stainless steel material has good corrosion resistance. A tension spring 15 is sleeved on the surface of the vertical rod 11. One end of the tension spring 15 is fixedly connected to the bottom block 12, and the other end of the tension spring 15 is fixedly connected to the lower filter bottle 4. The tension spring 15 can be made of spring steel or stainless steel. Spring steel has good elasticity and fatigue resistance, and stainless steel can maintain elasticity in a humid environment for a long time. The design of the tension spring 15 ensures that the bottom block 12 can continuously apply an upward pressure to jack up the filter element, preventing it from loosening or displacing under the impact of water flow, and ensuring the stability and service life of the filter element. Through the elastic force of the tension spring 15, the vertical rod 11 is pulled upward, thereby driving the cross plate 13 and the longitudinal plate 14 to firmly fix the filter element in the filter bottle, making the installation of the filter element more stable and reliable.

[0026] In this embodiment, when installing the filter element, it is only necessary to unscrew the filter bottle cap 2, and then install the filter element into the upper filter bottle 1 and the lower filter bottle 4 to complete the installation. At the same time, the size of the filter bottle can be adjusted according to the length of the installed filter element. During adjustment, the staff only needs to turn the cap 10 to turn the threaded rod 5. At this time, since a thread is provided in the side block A7, the threaded rod 5 can move within the side block A7. Subsequently, the threaded rod 5 can drive the annular flange 3 to move, and the annular flange 3 can then drive the upper filter bottle 1 to move. At the same time, the annular flange 3 drives the sliding rod 6 to slide within the side block B8. At this time, the upper filter bottle 1 slides within the lower filter bottle 4, and the distance between the upper filter bottle 1 and the lower filter bottle 4 can be adjusted, thereby expanding the size of the filter bottle. The present utility model simplifies the operation process and reduces the complexity of users installing the filter element by designing that unscrewing the filter bottle cap 2 can complete the installation of the filter element. By adjusting the distance between the upper filter bottle 1 and the lower filter bottle 4, it can accommodate filter elements of different lengths, realizing flexible compatibility of filter element sizes, expanding the usage range of the filter bottle. At the same time, through the structural design of the threaded rod 5 and the sliding rod 6, etc., the staff only needs to turn the cap 10 to adjust the size of the filter bottle without other complex tools, improving the convenience of adjustment. After the filter element is placed, due to the pulling force of the tension spring 15, the tension spring 15 can pull the bottom block 12 upward. Subsequently, the bottom block 12 can drive the vertical rod 11 to move, and the vertical rod 11 can then drive the horizontal plate 13 and the vertical plate 14 to move. At this time, the horizontal plate 13 and the vertical plate 14 can push the filter element upward, thereby making the installation of the filter element more stable and the filter element not easily displaced. The present utility model makes the filter element be pushed upward during installation and ensures that the filter element is more firmly installed and does not loosen by the structure of the tension spring 15 pulling the bottom block 12, the vertical rod 11, the horizontal plate 13 and the vertical plate 14. The pulling force of the tension spring 15 can continuously act to ensure that the filter element is not easily displaced by the impact of water flow during use, effectively ensuring the stability of the filter element, reducing the wear and displacement of the filter element during long-term use, increasing the durability and service life of the overall filter bottle. And because the tension spring 15 has elasticity, it can automatically adjust the pressing force according to the height of the filter element without additional manual adjustment, adapting to filter elements of different lengths or specifications, improving the compatibility of the equipment. At the same time, by using the automatic pulling structure of the tension spring 15, the manual adjustment of the position of the filter element during the installation process is reduced, the operation steps are simplified, and the installation difficulty is reduced.

[0027] Of course, the present utility model can also have many other embodiments. Based on this embodiment, other embodiments obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present utility model.
