Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to an activated carbon filter element replacement structure for a water purifier. Background Art

[0002] A water purifier, also known as a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to the requirements of water use. Generally, household water purifiers are small filters, and their technical core is the filter membrane in the filter element device. The current main technologies come from ultrafiltration membranes, RO reverse osmosis membranes, and nanofiltration membranes. After long-term use, household water purifiers will have slow water output, and at this time you need to replace the activated carbon filter element to solve the problem.

[0003] For example, the Chinese patent application number 202021797675.0 discloses an activated carbon filter element for a household water purifier that is easy to replace. In response to the problem that the activated carbon filter elements in existing household water purifiers are not easy to disassemble and replace, and replacement is time-consuming and labor-intensive, the following solution is proposed, which includes a water purifier, wherein two mounting grooves are provided on the top of the water purifier, and filter element bodies are installed in the two mounting grooves. Water ports are provided on both sides of the two filter element bodies, and a water inlet and a water outlet are provided on the inner wall of one side of the two mounting grooves respectively. The outer ring of the sealing ring is fixedly installed in the two mounting grooves, and the filter element body is in contact with the inner ring of the corresponding sealing ring. The bottom of the two filter element bodies is provided with a fixing groove. The utility model has a reasonable structure and is easy to operate. The activated carbon filter element in the household water purifier is easy to disassemble and replace, and can be disassembled and assembled without the need for special disassembly tools.

[0004] Although the above device has facilitated the replacement of the activated carbon filter element to a certain extent, in actual operation, one hand is required to rotate the unlocking block while the other hand is required to take the activated carbon filter element, which is still somewhat troublesome. For this reason, we propose an activated carbon filter element replacement structure for a water purifier to solve the above problem. Utility Model Content

After the filter element body 2 is fixed by the connecting component 3, the rubber ring 103 makes the filter element body 2 and the mounting seat 1 sealed to filter water.

[0027] Furthermore, two assembly chambers 301 are provided in the connecting component 3. The assembly chambers 301 are opened on both sides of the top of the mounting seat 1. The assembly chambers 301 on both sides are symmetrically distributed along the axis of the mounting seat 1. The assembly chambers 301 are connected to the connecting hole 102. A plurality of embedding grooves 302 are opened on the inner wall of the assembly chamber 301. The plurality of embedding grooves 302 are evenly distributed around the axis of the assembly chamber 301. A transverse groove 303 is opened on one side of the bottom of the plurality of embedding grooves 302. A positioning groove 304 is opened on the top of one end of the transverse groove 303 away from the embedding groove 302. The embedding groove 302, the transverse groove 303 and the positioning groove 304 are connected. The positioning groove 304 is close to the assembly An installation chamber 305 is provided on one side of the bottom of the inner cavity of the groove. A fixed cylinder 306 is fixedly connected to the inner wall of the installation chamber 305. A rotating roller 307 is built into the fixed cylinder 306. One end of the rotating roller 307 away from the axis of the assembly chamber 301 is rotatably connected to the bottom of the inner cavity of the fixed cylinder 306. A coil spring 308 is sleeved on the surface of the rotating roller 307. The coil spring 308 is placed in the fixed cylinder 306. One end of the coil spring 308 is fixedly connected to the rotating roller 307. The other end of the coil spring 308 is fixedly connected to the inner wall of the fixed cylinder 306. The surface of the end of the rotating roller 307 located outside the fixed cylinder 306 is sleeved with a top plate 309. One end of the top plate 309 is fixed to the rotating roller 307. The other end of the top plate 309 extends into the positioning groove 304. The end of the top plate 309 located in the positioning groove 304 is an elliptical structure.

When disassembly is required, it is only necessary to press the filter element body 2 first and then rotate it so that the positioning seat 202 is away from the positioning groove 304, and the filter element body 2 can be taken out.

[0028] Working principle: When installing the filter element body 2, use one hand to place the filter element body 2 in the assembly chamber 301, first put it in and then rotate it. The multiple positioning seats 202 around it move down along the embedded groove 302 to the last moving positioning groove 304 in the transverse groove 303. When the positioning seat 202 is in contact with the top plate 309, due to its own triggering inclined surface 203 structure and the elliptical structure of the top plate 309, the positioning seat 202 can squeeze the top plate 309, so that the top plate 309 can enter the installation chamber 305 by the elastic force of the coil spring 308. In daily use The top plate 309 in the mounting chamber 305 has a supporting force on the positioning seat 202, so that the positioning seat 202 can be restricted in the positioning groove 304 and will not fall off, thereby stabilizing the positioning seat 202 and the filter element body 2 and making them stable. When disassembly is required, it is only necessary to press the filter element body 2 first and then rotate it to make the positioning seat 202 away from the positioning groove 304, and the filter element body 2 can be taken out. Compared with the existing activated carbon filter element replacement structure, this device only requires one hand to complete all operations, and is stable, very convenient, fast and practical.
