Technical Field

[0001] The invention relates to the technical field of water purification, in particular to a water purification filter element. Background Art

[0002] The water purification filter element is the core component of water treatment equipment. Its function is to remove impurities, pollutants and harmful substances in the water and improve water quality. Common filter element types include PP cotton filter element, activated carbon filter element, ultrafiltration membrane filter element and reverse osmosis membrane filter element. Activated carbon filter element is usually composed of carbon column, upper cover, bottom cover and outer filter screen. During normal use, as time goes by, the carbon column inside the filter element will continue to adsorb various impurities in the water. When the adsorption amount reaches a certain level, the purification effect of the filter element will decrease. At this time, the staff needs to replace the filter element in time.

[0003] However, since the upper cover, bottom cover, carbon column and outer filter screen of the activated carbon filter element are fixedly connected, when replacing the filter element, the entire used filter element can only be discarded as a whole. In this way, the filter screen, upper cover, bottom cover and other components on the filter element are also discarded, resulting in a huge waste of resources. Summary of the invention

A second magnet is rotatably connected inside the mounting frame, a movable groove is opened inside the shaft rod of the second magnet, a spring is fixedly connected inside the movable groove, a square rod is slidably connected inside the movable groove, and a handle is fixedly connected to one end of the square rod.

[0006] Specifically, the top of the filter is slidably inserted into the interior of the upper cover, the top of the carbon column is slidably inserted into the interior of the upper cover, the center position of the upper cover is in a blocked state, and the center position of the bottom cover is in a transparent state.

[0007] Specifically, the mounting block is fixedly connected to the outer wall of the filter near the top position, the first magnet is slidably connected inside the sliding groove, the limit blocks are fixedly connected to the limit rod, and the top end of the limit rod slides through the top wall of the mounting block.

[0008] Specifically, the annular groove is opened on the upper cover, the limiting groove is opened at the position of the upper cover corresponding to the annular groove, the limiting groove and the annular groove are in a communicating state, the top end of the limiting rod is slidably inserted into the inside of the limiting groove, the mounting frame is fixedly connected to the bottom end position of the annular groove on the upper cover, the bottom end of the mounting block abuts against the top end of the mounting frame, one end of the spring is fixedly connected to one end of the square rod, the handle is slidably connected to the inside of the front wall of the mounting frame, and the mounting block is slidably connected to the inside of the annular groove.

[0009] Specifically, the bottom end of the first magnet is set as the north pole, the top end of the second magnet is set as the north pole, and the bottom end of the second magnet is set as the south pole.

[0010] Beneficial effects of the present invention: (1) With the cooperation of the annular groove, the first magnet, the second magnet, the limit rod and the limit groove, the carbon column can be firmly fixed at the center position between the upper cover and the bottom cover. When the carbon column in the filter element needs to be replaced, only the upper cover needs to be gently turned, and the various components will respond in conjunction, thereby releasing the connection between the upper cover and the outer filter screen. Subsequently, the carbon column between the upper cover and the bottom cover can be easily removed and replaced with a new carbon column, so that the user does not need to discard the entire filter element, which effectively reduces the waste of resources and saves the user the resource investment cost.

[0011] (2) The operation design of the present invention is extremely sophisticated. The filter element can be easily disassembled by simply performing a simple and clear operation step of pulling and turning. The operation process is extremely convenient and does not require professionals to have complex professional skills or rich operating experience. Even ordinary users can complete the replacement of the filter element calmly, which greatly broadens the application scope of the filter element and enhances its versatility and convenience in different usage scenarios. In addition, the overall structural design of the present invention is simple and sophisticated, which reduces the material cost and process cost of the filter element in the production and manufacturing stage and the maintenance cost during use, so that the filter element can be put into operation in a more efficient and stable state, thereby better completing the water purification work.

At this time, the upper cover 1 is separated from the filter screen 3 and the carbon column 4, and the carbon column 4 can be pulled out from the bottom cover 2, and then the filter screen 3 is properly cleaned, and finally a new carbon column 4 is assembled to the bottom cover 2, and then the upper cover 1 is reconnected with the filter screen 3 and the carbon column 4, and then the North Pole face of the second magnet 64 is rotated to the top again through the pull handle 68 and the square rod 67, and then the pull handle 68 is released, and the upper cover 1 is rotated to the initial position, and the mounting block 51 is reconnected with the annular groove 61. When the top of the mounting frame 62 corresponds to the bottom of the mounting block 51, a great repulsive force will be generated between the first magnet 56 and the second magnet 64 because they are at the same level, and the position of the second magnet 64 remains unchanged. The first magnet 56 will drive the limiting rod 55 to move upward, and the moved limiting rod 55 will be inserted into the limiting groove 63 again. At this time, the upper cover 1 cannot be rotated or moved upward, and the assembly of the filter element is completed. The filter element with the replaced carbon column 4 can be reassembled on the water delivery pipe, so that the user does not need to discard the entire filter element, which effectively reduces the waste of resources and saves the user the resource investment cost.
