[0002] The filter cartridges of pure water equipment are usually integrated inside a sealed tank, requiring the removal of multiple bolts or tools, which is cumbersome and time-consuming. Therefore, there is a special need for a pure water treatment device that makes it easy to replace the filter cartridges.

[0003] A reverse osmosis pure water device, authorized by announcement number CN216472525U, includes symmetrically arranged pretreatment components and a pure water treatment component fixedly connected to the bottom of the two pretreatment components facing each other. The pretreatment components include a pretreatment tank with a pretreatment chamber at the top, and a filter component detachably installed on the top of the pretreatment chamber. The filter component includes a water storage tank with connecting ears arranged in a ring array on the top of its outer edge and a threaded annular groove centrally located at the bottom of the water storage tank. A connecting ring can be threadedly installed in the threaded annular groove. The filter component also includes two symmetrically arranged support rings. A primary filter element is fixedly installed between the two support rings facing each other, and the bottom support ring is fixedly connected to the connecting ring. This reverse osmosis pure water device has a reasonable structure, facilitates pre-filtration of water, and makes it easy to replace and clean the filter element, making it highly practical.

[0004] However, while increasing filtration levels can improve the purification effect of a reverse osmosis pure water system, it sacrifices the convenience of filter replacement and maintenance costs, making it difficult for users to operate.

[0005] To address the aforementioned issues, a pure water treatment device with easily replaceable filter cartridges is proposed. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example

[0028] like Figure 1-3As shown, the system includes a bottom tank 1, inside which a main filter element replacement mechanism 2 is installed. A top tank 3 is welded above the bottom tank 1, inside which a pre-filter element replacement mechanism 4 is installed. The main filter element replacement mechanism 2 includes a side groove 201 formed on one side of the top of the bottom tank 1. A sealing strip 202 is provided on one side of the bottom tank 1 and is located inside the side groove 201. A movable cover plate 203 is rotatably connected to one side of the top of the bottom tank 1. A fixing ring 204 is welded to the side of the movable cover plate 203 near the inner wall of the bottom tank 1. The inner wall of the fixing ring 204 is fitted with a first filter element 205. The main filter element replacement mechanism 2 also includes a fastening ring 206 wrapped around the outside of the bottom tank 1. A groove 207 is provided on one side of the surface of the movable cover plate 203. A buckle 208 is installed on the top of the fixing ring 204. A first mounting ring 209 is installed on the top outer side of the first filter element 205. A sealing layer 210 is bonded to the side of the fastening ring 206 near the bottom tank 1. A first bolt 211 is passed through the opening of the fastening ring 206. A through hole 212 is provided on the top of the first mounting ring 209.

[0029] It should be noted that in this embodiment, the device consists of a bottom tank 1 and a top tank 3. The bottom tank 1 is equipped with a main filter element replacement mechanism 2, which is mainly used for deep purification of water. The top tank 3 is equipped with a pre-filter element replacement mechanism 4, which is mainly used for preliminary filtration of water. When the first filter element 205 needs to be installed, the movable cover 203 is opened. At this time, the first filter element 205 is installed on the inner wall of the fixing ring 204. The first mounting ring 209 on the outer side of the top of the first filter element 205 corresponds to the top of the fixing ring 204, and the buckle 208 is engaged. The first filter element 205 is fixed to the fixing ring 204 by passing through the through hole 212 at the top of the first mounting ring 209. The movable cover 203 is closed, and the movable cover 203 rotates around the bottom tank 1, causing the first filter element 205 to pass through the sealing strip 202 on one side of the movable cover 203. The sealing strip 202 plays a sealing role to prevent water from leaking from the connection between the movable cover 203 and the bottom tank 1. When the movable cover 203 and the bottom tank 1 are closed, the fixing ring 204, the first filter element 205 and the first mounting ring 209 are all located inside the bottom tank 1.

[0030] Among them, a fastening ring 206 is wrapped around the outside of the bottom tank 1, and a first bolt 211 is inserted through the opening of the fastening ring 206. By tightening the first bolt 211, the fastening ring 206 is fastened to the outside of the bottom tank 1. A sealing layer 210 is bonded to the side of the fastening ring 206 near the bottom tank 1, which further enhances the sealing performance of the device. The side groove 201 provides installation and movement space for the movable cover 203. The groove 207 is opened on one side of the surface of the movable cover 203 to facilitate the operator to open and close the movable cover 203.

[0031] like Figure 4 , 5As shown, the pre-filter replacement mechanism 4 includes a second mounting ring 401 installed on the inner wall of the top tank 3. A second filter element 402 is fixedly installed on the bottom wall of the second mounting ring 401. A coarse filter basket 403 is fitted into the top wall of the second mounting ring 401. The pre-filter replacement mechanism 4 also includes a circular groove 404 opened on the top wall of the top tank 3. A tank cover 405 is rotatably connected to one side of the top of the top tank 3. A limiting groove 406 is opened on the top of the second mounting ring 401. A limiting post 407 is installed at the bottom of the second mounting ring 401. A limiting block 408 is welded to the outside of the coarse filter basket 403. A second bolt 409 is passed through one side of the tank cover 405 and is connected to the top tank 3 through the second bolt 409.

[0032] It should be noted that in this embodiment, the can lid 405 is opened, and the coarse filter basket 403 is fitted into the top wall of the second mounting ring 401. The limiting block 408 on the outside of the coarse filter basket 403 corresponds one-to-one with the limiting groove 406 opened on the top of the second mounting ring 401, ensuring that the coarse filter basket 403 is accurately installed on the second mounting ring 401. At the same time, the limiting post 407 at the bottom of the second mounting ring 401 corresponds one-to-one with the circular groove 404, ensuring that the second filter element 402 is fixedly installed on the bottom wall of the second mounting ring 401. Then the can lid 405 is closed, and the second bolt 409 is inserted through one side of the can lid 405 and connected to the top can body 3. By tightening the second bolt 409, the can lid 405 is fixed on the top can body 3. The bottom of the can lid 405 is sunken and located at the top of the second filter element 402 and the coarse filter basket 403, which plays a limiting role for the second filter element 402 and the coarse filter basket 403, preventing them from shifting during the operation of the device.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-5 Main filter element replacement: First, loosen the first bolt 211, open the fastening ring 206, then open the movable cover 203, pinch the top of the clip 208, and remove the clip 208 from the through hole 212 of the first mounting ring 209. Then, remove the first filter element 205 from the fixing ring 204, replace it with a new first filter element 205, and reinstall it according to the installation steps.

[0035] Pre-filter replacement: Loosen the second bolt 409, open the can cover 405, remove the coarse filter basket 403 from the second mounting ring 401, replace the coarse filter basket 403 with a new one, and replace the second filter element 402 as needed. After replacement, reinstall according to the installation steps.
