Description

Technical Field

[0001] The utility model relates to the technical field of water purifier filter elements, in particular to a water purifier filter element which is easy to disassemble. Background Art

[0002] As people's awareness of environmental protection, energy saving and health gradually increases, water purifiers have become an important water purification appliance in people's homes. In order to improve the water purification effect of the water purifier, a water purifier in the related art is equipped with multiple filter cartridges, and each filter cartridge is connected to a filter cartridge seat, and the multiple filter cartridge seats are fixed to the machine of the water purifier. Since the filter cartridge plays a role in filtering water, the filter cartridge needs to be cleaned or replaced after a period of use. After searching, the prior art (publication number: CN220223656U) records "a water purifier filter element that is easy to disassemble, including a filter cartridge, a filter element and a sealing cover. The filter element is installed inside the filter cartridge. A connecting mechanism is arranged around the surface of the sealing cover. The sealing cover is connected to the filter cartridge through the connecting mechanism. Pipe interfaces are provided on both sides of the top of the sealing cover. When the locking claw moves into the lock groove, the pin rod slidably hinged at the bottom of the locking claw moves into the installation groove and drives the limit ring to squeeze the spring. The spring is compressed and stressed into the limit sleeve. When the filter cartridge needs to be removed, the movable sleeve is rotated in the opposite direction to disengage from the locking claw. At this time, the spring is not under pressure and releases the stored force to push the pin rod to move outside the installation groove. At this time, the locking claw pops out from the lock groove, causing the filter cartridge to fall off from the sealing cover, making it easy to quickly remove and replace the filter element."

[0003] Although the easy-to-disassemble water purifier filter element in the prior art has achieved the effect of easy disassembly, there are still some shortcomings: the filter element involved in the existing water purifier filter element lacks an installation positioning device inside the filter cartridge, which makes it easy to deflect when connected to the water purifier. Secondly, the existing water purifier filter element generally has multiple groups. For example, the filter element generally includes PP cotton material filter element, granular activated carbon filter element and fixed activated carbon filter element, while the existing filter element structure can only be disassembled one at a time, resulting in efficiency deviation. Utility Model Content

[0004] In order to overcome the defects of the prior art, a water purifier filter element that is easy to disassemble is provided to solve the problem that the existing water purifier filter element lacks the installation and positioning effect of the internal filter element and still has the problem of low disassembly efficiency.

[0008] Furthermore, the connecting member includes a transfer rod fixed on the upper side of the bottom plate, and the upper end of the transfer rod is rotatably connected to a threaded cylinder.

[0009] Furthermore, the connecting assembly includes a connecting rod connected to the outer shell wall of the water purifier body, and the lower end of the connecting rod is connected to a threaded rod, and the lower end of the threaded rod is connected to a guide rod, and the guide rod is matched and plugged with the threaded barrel.

[0010] Furthermore, the upper port of the guide seat is configured as a bell-mouth structure, and a positioning groove is provided at the bottom of the guide seat, and the elastic sheet is movably connected to the groove walls around the positioning groove.

[0011] Furthermore, a sliding groove is provided on the inner groove wall of the positioning groove, a spring is provided in the sliding groove, and a slider is slidably connected in the sliding groove, and the slider is connected to both ends of the elastic sheet of the arc structure.

[0012] The beneficial effects of the utility model are:

[0013] 1. When disassembling, hold the threaded barrel with both hands and rotate it, so that the relative displacement between the threaded barrel and the threaded rod, as well as the joint effect of the bottom plate, can make the three groups of filter element bodies be removed from the water purifier body at the same time, and then replace the internal filter element, and then plug the threaded barrel and the guide rod into place at the same time and continue to rotate and connect with the threaded rod, so that the card end at the upper end of the filter element body is plugged and squeezed and fixed with the card interface at the lower end of the water purifier body. In the process, the sealing effect of the connection is achieved by the inner and outer two sealing rings, so as to facilitate the disassembly and replacement of multiple groups of filter elements, and improve the disassembly efficiency;

[0014] 2. When replacing and installing the filter element, the bottom of the new filter element is guided into the positioning groove through the bell-shaped structure of the upper port of the guide seat. At this time, the outer wall of the filter element squeezes the elastic sheet of the arc structure, so that the elastic sheet moves outward to push the slider to squeeze the spring. Then, through the reaction force of the spring and the elastic action of the elastic sheet itself, the filter bottom is clamped and fixed, thereby ensuring the stability of the filter element inside the filter cartridge.
