Technical Field

[0001] This utility model relates to the field of filter cartridge technology, and more specifically, to a quick-connect structure for a cartridge body. Background Technology

[0002] A "filter cartridge" generally refers to a cylindrical device used to filter impurities from liquids or gases. A filter cartridge is a cylindrical element used for filtration, and is generally divided into filter cartridges for filtering gaseous media and filter cartridges for filtering liquid media. Filter cartridges for filtering liquid media are typically installed inside pipeline filters.

[0003] Currently, existing filter cartridges generally use threaded connections or external connection structures for connection. This requires specific tools for disassembly and assembly, making the process cumbersome and inconvenient. Therefore, it is necessary to propose a quick-connect structure for the cartridge to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-connect structure for the filter cylinder, which aims to improve the problem that existing filter cylinders generally use threaded connections or external connection structures for connection, which requires specific tools for disassembly and assembly, making disassembly and assembly cumbersome and inconvenient.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a quick-connect structure for a cylindrical body, including a cylindrical body structure and an end cap structure.

[0007] The cylindrical structure includes a cylindrical body and a filter element. The filter element is installed inside the cylindrical body. A locking block is fixed on the upper outer surface of the cylindrical body, and a limiting groove is formed on the lower surface of the locking block. The end cap structure includes an end cap and a retaining sleeve. The end cap is snapped onto the upper end of the cylindrical body. A slide is formed on the inner surface of the end cap. The locking block is slidably connected to the slide. A limiting protrusion is formed on the inner surface of the slide. The limiting groove is snapped onto the limiting protrusion. The retaining sleeve is integrally formed inside the end cap and is snapped onto the upper end of the filter element.

[0008] In one embodiment of the present invention, a locking protrusion is formed at the bottom of the cylinder, and a locking groove matching the locking protrusion is formed at the bottom of the filter element, the locking groove engaging with the locking protrusion.

[0009] In one embodiment of the present invention, an annular outer edge and a first annular groove are formed on the upper outer surface of the cylinder. The first annular groove is located at the upper end of the annular outer edge, and the annular outer edge fits against the end cap. A first annular sealing ring is sleeved inside the first annular groove, and the first annular sealing ring is slidably connected to the inner surface of the end cap.

[0010] In one embodiment of this utility model, a flow guiding channel is formed inside the filter element, and a second annular groove is provided at the upper end of the filter element. A second annular sealing ring is sleeved inside the second annular groove, and the second annular sealing ring is slidably connected to the inner surface of the sleeve.

[0011] In one embodiment of this utility model, two of each of the first and second annular grooves are provided, and the locking blocks are circumferentially distributed at the upper end of the cylinder.

[0012] In one embodiment of the present invention, a liquid inlet is formed on one side of the end cap, and a threaded structure is formed on the surface of the liquid inlet.

[0013] In one embodiment of the present invention, a liquid outlet is formed on one side of the sleeve, the liquid outlet extends to the outside of the end cap, and a threaded structure is formed on the liquid outlet.

[0014] The beneficial effects of this utility model are as follows: The quick-connect structure of the cylinder obtained by the above design allows for convenient and rapid disassembly. When in use, the end cap is snapped onto the cylinder, aligning the locking block on the cylinder with the slide rail on the end cap, and simultaneously aligning the sleeve with the upper end of the filter element. Rotating the end cap 90 degrees allows the locking block to slide in the slide rail, and the limiting groove to engage with the limiting protrusion for positioning and fixation. Simultaneously, the first annular sealing ring on the cylinder slides against the end cap, while the second annular sealing ring on the upper end of the filter element slides inside the sleeve to seal it. The inlet and outlet pipes are then connected to external pipes. During filtration, liquid enters through the inlet pipe, then flows through the filter element into the internal guide channel, and exits through the sleeve and outlet pipe. This allows for disassembly without the need for specific tools or external connecting structures; disassembly can be completed simply by rotating the cylinder, making disassembly more convenient and faster. Furthermore, the interlocking of the limiting groove and limiting protrusion prevents loosening, making assembly more stable. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example

[0025] Please see Figures 1-6 This utility model provides a technical solution: a quick-connect structure for a cylindrical body, including a cylindrical body structure 100 and an end cap structure 200.

[0026] Please see Figures 1-5 The cylindrical structure 100 includes a cylindrical body 110 and a filter element 130. The filter element 130 is installed inside the cylindrical body 110. A locking block 140 is fixed on the upper outer surface of the cylindrical body 110, and a limiting groove 141 is formed on the lower surface of the locking block 140.

[0027] The bottom of the cylinder 110 has a locking protrusion 111, and the bottom of the filter element 130 has a locking groove 133 that matches the locking protrusion 111. The locking groove 133 engages with the locking protrusion 111, which improves the stability of the filter element 130. The upper outer surface of the cylinder 110 has an annular outer edge 112 and a first annular groove 113. The first annular groove 113 is located at the upper end of the annular outer edge 112, which fits against the end cap 210. A first annular sealing ring 120 is fitted inside the first annular groove 113. The first annular sealing ring 120 is slidably connected to the inner surface of the end cap 210. Here, the two first annular sealing rings 120 are used to improve the sealing between the end cap 210 and the cylinder 110, which helps to prevent leakage.

[0028] The filter element 130 has a flow channel inside, and a second annular groove 131 is formed at the upper end of the filter element 130. A second annular sealing ring 132 is fitted inside the second annular groove 131, and the second annular sealing ring 132 is slidably connected to the inner surface of the sleeve 220. There are two of each of the first annular groove 113 and the second annular groove 131. The locking blocks 140 are circumferentially distributed at the upper end of the cylinder 110. The two second annular sealing rings 132 can improve the sealing between the sleeve 220 and the filter element 130 and prevent leakage. At the same time, the locking blocks 140 are matched with the slide 211, which can improve the installation firmness.

[0029] Please see Figures 1-6 The end cap structure 200 includes an end cap 210 and a retainer 220. The end cap 210 is snapped onto the upper end of the cylinder 110. A slide 211 is formed on the inner surface of the end cap 210. The retainer 140 is slidably connected to the slide 211. A limiting protrusion 212 is formed on the inner surface of the slide 211. A limiting groove 141 is snapped onto the limiting protrusion 212. The retainer 220 is integrally formed inside the end cap 210 and is snapped onto the upper end of the filter element 130.

[0030] One side of the end cap 210 has an inlet port 230 with a threaded structure on its surface. One side of the ferrule 220 has an outlet port 221 that extends to the outside of the end cap 210. The outlet port 221 has a threaded structure, which allows for easy connection with external water inlet and outlet pipes.

[0031] Specifically, the working principle of this quick-connect structure is as follows: In use, the end cap 210 is snapped onto the cylinder 110, aligning the locking block 140 on the cylinder 110 with the slide rail 211 on the end cap 210. Simultaneously, the retaining sleeve 220 is aligned with the upper end of the filter element 130. Then, the end cap 210 is rotated 90 degrees, causing the locking block 140 to slide within the slide rail 211, and the limiting groove 141 to engage with the limiting protrusion 212 for positioning and fixation. At the same time, the first annular sealing ring 120 on the cylinder 110 slides between itself and the end cap 210, while the second annular sealing ring 132 at the upper end of the filter element 130 engages with the retaining sleeve 220. The interior of filter element 20 is sealed by sliding. At this time, the inlet 230 and outlet 221 are connected to the external pipes respectively. During filtration, the liquid enters through the inlet 230, then enters the guide channel inside the filter element 130 through the filter element 130, and is discharged through the sleeve 220 and outlet 221. In this way, during disassembly, no special tools or external connection structure are required. The disassembly operation can be completed by simply rotating, making disassembly more convenient and faster. At the same time, the mutual locking of the limiting groove 141 and the limiting protrusion 212 can prevent loosening and make the assembly more stable.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
