[0002] With the improvement of people's living standards and the enhancement of awareness of healthy drinking water, water purifiers have become an indispensable water treatment equipment in homes and commercial places. Their core function is to remove impurities, bacteria, heavy metals and other harmful substances from the water through internal filter cartridges in order to provide clean and safe drinking water. As the core consumable component of water purifiers, the integrity of the filter cartridge and the ease of replacement are directly related to the quality of the output water, user experience and long-term stable operation of the equipment. However, existing water purifiers mostly use integrated filter cartridges or multiple cartridges installed together. Replacing these cartridges requires disassembling the entire filter assembly or performing complex disassembly and reassembly, making maintenance inconvenient and time-consuming. Furthermore, traditional water purifiers have inlet, outlet, and wastewater pipes located in different places, leading to complex external connections and high installation costs. Therefore, we provide a water purifier with a quick-maintenance filter cartridge to solve the above problems. Utility Model Content

[0020] 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.

[0021] Please see Figures 1 to 4 This utility model is a water purifier with a quick-maintenance filter element, including a housing 1. The housing 1 serves as the main structure of the water purifier, accommodating all internal components and providing a water flow channel. The housing 1 is connected to an inlet pipe 101 and a drain pipe 102 to form a closed filtration system. A bottom cover 2 is installed at the lower end of the housing 1 to close the lower end of the housing 1 and to install a drain bend 201. A top cover 3 is installed at the upper end of the housing 1 to close the upper end of the housing 1 and to install a limiting plate 301, a pressure gauge 4, and other structures. An inlet pipe 101 connected to the interior is fixed to the lower part of the surface of the housing 1. The inlet pipe 101 is located at the lower end of the housing 1, allowing water to flow from bottom to top through the filter element 6, improving filtration efficiency. A positioning block 103 is provided at the bottom of the interior of the housing 1 to position and fix the filter element 6, ensuring that the lower end of the filter element 6 is sealed and to guide water flow into the filter element 6. The upper end face of the positioning block 103 has multiple sets of sealing openings 106 arranged in a ring around its periphery. Inside the housing 1 above the positioning block 103, there are multiple sets of filter strips 6, each positioned directly above the sealing opening 106. The filter strips 6 are used to physically filter impurities in the water, and each filter strip 6 is installed independently for easy individual replacement and to extend the overall lifespan. The inner side of the top cover 3 is provided with a limiting plate 301, which is used to limit the upper position of the filter strips 6 and cooperates with the positioning rod 601 to keep the filter strips 6 vertical and stable and prevent shaking. The upper end face of the limiting plate 301 is fixed with multiple sleeve rods 302, each positioned directly above the filter strips 6. The sleeve rods 302 are fitted with hanging ropes 304 for pulling the filter strips 6. The surface of the bottom cover 2 is fixed with a drain bend 201.

[0022] Specifically, a positioning rod 601 is provided between multiple filter element strips 6. The positioning rod 601 is located at the center between the multiple filter element strips 6 to stabilize the entire filter element assembly and prevent the filter element strips 6 from shifting. The upper end face of the positioning block 103 located in the middle of multiple sealing ports 106 has an installation groove 105. The lower end of the positioning rod 601 is inserted into the installation groove 105. The lower end face of each filter element strip 6 is fixed with a sealing block 602 inserted into the corresponding sealing port 106. The sealing block 602 is fixed in place at each... The lower end face of the filter element 6 is inserted into the corresponding sealing port 106 to form a seal. The leakage holes on the sealing block 602 are concentrated on the inner side of the filter element 6. This ensures that water can only be filtered through the inside of the filter element 6, preventing unfiltered water from leaking out. A sleeve 303 is fixed at the middle of the lower end face of the limiting plate 301. The upper end of the positioning rod 601 is inserted into the sleeve 303. The cooperation between the sleeve 303 and the positioning rod 601 ensures that the filter element 6 remains vertical during operation.

[0023] Furthermore, a conical cylinder 104 is fitted into the recessed position at the lower end of the positioning block 103. The conical cylinder 104 passes through the pipe opening at the lower end of the housing 1 and is spirally connected to the upper end of the drain bend 201. The conical cylinder 104 is used to collect filtered water and guide the water into the drain bend 201, while preventing impurities from entering the drain bend 201. Both the conical cylinder 104 and the positioning block 103 have gaps with the inner wall of the housing 1. A drain pipe 102 is fixed to the surface wall of the housing 1 below the conical cylinder 104. The drain pipe 102 is used to periodically discharge the sediment or pollutants accumulated inside the housing 1. Since there are gaps between the conical cylinder 104, the positioning block 103 and the inner wall of the housing 1, dirt will concentrate and settle inside the housing 1 below the conical cylinder 104.

[0024] The housing 1 is fitted with a locking buckle 5 on its surface. The top cover 3 is connected to the housing 1 by the locking buckle 5 to ensure overall sealing and facilitate quick opening for maintenance. The housing 1 and the top cover 3 are assembled and combined by the locking buckle 5. A pressure gauge 4 is installed on the upper part of the outside of the top cover 3, and the probe of the pressure gauge 4 passes through the top cover 3 and is located in the housing 1.

[0025] The operation process of this embodiment is as follows: First, water flows into the housing 1 from the water inlet pipe 101, and the water will gradually penetrate into the interior of the filter strip 6. The water is filtered by the filter strip 6, and the filtered water flows into the conical cylinder 104 from the pores of the sealing block 602. Then the drain bend 201 can be opened to drain the filtered water. The pressure gauge 4 used can monitor the pressure inside the housing 1 in real time. When the filter element needs to be replaced, open the locking buckle 5, then open the top cover 3. By removing each hanging rope 304 from the upper end of the sleeve rod 302 and pulling the filter element strip 6 with the hanging rope 304, one or more filter element strips 6 can be taken out. After replacing the new filter element strip 6, reinsert the sealing block 602 at the lower end of the filter element strip 6 into the sealing port 106, and hang the hanging rope 304 back on the sleeve rod 302. Close the top cover 3 and lock the locking buckle 5 to achieve quick installation and removal of the filter element strip 6. Finally, the drain pipe 102 can be opened periodically to clean the dirt.
