Technical Field
[0001] This application relates to the field of filter technology, and in particular to a filter cartridge housing that is easy to install and remove. Background Technology
[0002] Filters, as common fluid purification devices, are widely used in many fields such as water treatment, petrochemicals, food and pharmaceuticals, and the automotive industry. Their core function is to intercept and remove particulate impurities from fluids through internal filter elements (such as filter screens, membranes, bags, or media). The filter housing, as a key component that houses and secures the filter elements, directly affects the sealing performance, pressure resistance, and ease of maintenance of the filtration system.
[0003] Chinese utility model patent CN223248890U discloses a quick-release structure for water purifier filter cartridges, relating to the field of water purifier design. It includes a water purifier, a filter cartridge housing, and an end cap. A filter cartridge is fitted inside the filter cartridge housing with a clearance fit, and the filter cartridge housing is detachably installed inside the water purifier. Four sets of snap-fit protrusions are formed on the inner side of the end of the filter cartridge housing, arranged in a circular array and spaced apart. Four sets of snap-fit edges are formed on the outer side of the end cap at the end inserted into the filter cartridge housing. These four sets of snap-fit edges are inserted into the filter cartridge housing through the gaps between the four sets of snap-fit protrusions, and are twisted and snapped onto the snap-fit protrusions. Two sliding locks are slidably fitted on the end face of the end cap. An outer cover is fixedly installed on the end cap, and a screw is rotatably fitted inside the outer cover. The screw drives the two sliding locks to extend or retract. Compared with existing technologies, the advantages of this utility model are that it ensures stable assembly of the end cap, facilitates operation, and avoids potential safety hazards.
[0004] In actual use, the filter element housing end cap is not easy to install and cannot be installed quickly. Summary of the Invention
[0005] To facilitate the quick installation of the filter cartridge housing end cap, this application provides a filter cartridge housing that is easy to install and remove.
[0006] This application provides a filter cartridge housing that is easy to install and disassemble, using the following technical solution:
[0007] A filter cartridge housing that is easy to install and disassemble includes a filter cartridge housing, one end of which has an opening, and the other end is provided with an inlet and an outlet. It also includes an end cap for closing the opening. The top of the filter cartridge housing is provided with a plurality of buckles. The end cap is provided with an insertion groove for the buckles to be inserted into the top of the filter cartridge housing. The bottom of the insertion groove is provided with a snap-fit groove for the buckles to be engaged. The snap-fit groove is connected to the insertion groove. It also includes a release component for disengaging the buckles from the snap-fit groove.
[0008] By adopting the above technical solution, the circumferential buckle on the top of the filter element housing cooperates with the insertion groove and snap-fit groove of the end cover, realizing the quick installation and fixation of the end cover without additional tools. At the same time, the easy disassembly of the filter element housing is facilitated by the detachment of the components, which greatly improves the disassembly of the filter element housing. This is beneficial for the recycling and replacement of the filter element, reduces the damage to components during the disassembly process, facilitates the installation and disassembly of the filter element housing, and facilitates the quick installation of the filter element housing end cover.
[0009] Optionally, the detachment component includes a cover block, and a plurality of detachment blocks are circumferentially arranged on the side of the cover block near the end cover. Each of the plurality of detachment blocks corresponds to a insertion slot. The top of the end cover has a detachment groove for the detachment blocks to slide through. The detachment groove is connected to the bottom of the snap-fit groove. The snap-fit has a chamfer for the detachment blocks to abut against. When the detachment blocks slide toward the snap-fit and abut against the chamfer, the detachment blocks drive the snap-fit to disengage from the snap-fit groove.
[0010] By adopting the above technical solution, the detachment component adopts a cover block and a detachment block design. By pushing the cover block, the detachment block can be driven to slide, so that the buckle can be detached from the snap-fit groove, realizing one-click disassembly of the end cover. Users do not need professional tools or forceful operation, which improves disassembly efficiency and user experience, while reducing the risk of damage to the shell during disassembly.
[0011] Optionally, the buckle is a flexible plastic part.
[0012] By adopting the above technical solution, the elastic plastic part can deform to a certain extent when the buckle is engaged, which facilitates a firm engagement of the buckle.
[0013] Optionally, the top of the end cap is provided with a groove, and the release assembly also includes a spring. The spring is disposed at the bottom of the groove, and the direction of the spring force is the same as the sliding direction of the release block. One end of the spring is disposed at the bottom of the groove, and the other end is disposed on the cover block. The spring drives the release block to slide away from the buckle.
[0014] By adopting the above technical solution, the spring is set in the groove of the end cap, providing an automatic reset function, ensuring that the release block is away from the buckle when not in operation, thus avoiding accidental release or misoperation.
[0015] Optionally, a limiting post is provided at one end of the cover block near the end cover, and a sliding groove is provided at the bottom of the groove for the limiting post to slide. The spring is sleeved on the limiting post.
[0016] By adopting the above technical solution, the sliding groove allows the limiting post to have a sufficient sliding distance. The spring is sleeved on the limiting post, which enhances the stability and guiding nature of the spring, ensures the accuracy and smoothness of the disengagement action, and further improves the durability and operational consistency of the disengagement component.
[0017] Optionally, it may also include a plurality of elastic waterproof gaskets, wherein the elastic waterproof gaskets are disposed on the side wall of the opening and the outer wall of the end cap abuts against the elastic waterproof gaskets.
[0018] By adopting the above technical solution, the connecting assembly achieves a secure connection between the first and second housings through sleeve blocks, ring blocks, and threaded connections, while providing excellent sealing performance. The threaded connection allows users to easily assemble and disassemble by rotation, avoiding forced disassembly and facilitating the reuse and recycling of the housings. This design also ensures a tight fit at the connection points, effectively preventing liquid leakage from inside the filter element.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] 1. The circumferential buckle on the top of the filter element housing engages with the insertion and snap-fit grooves of the end cap, enabling quick installation and fixation of the end cap without additional tools, thus facilitating the rapid installation of the filter element housing end cap;
[0021] 2. The end cap can be easily removed with one click using the cover block and release block, eliminating the need for professional tools or forceful operation, thus improving disassembly efficiency and user experience;
[0022] 3. An automatic reset function is provided by a spring, while ensuring that the release block is away from the latch when not in operation to avoid accidental release or misoperation. Attached Figure Description
