[0004] However, because the filter body itself has a tubular structure, machining the installation structure 131 within such a tubular structure undoubtedly greatly increases the difficulty of manufacturing the filter body. This increased manufacturing difficulty not only raises production costs but may also affect production efficiency. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] For reference as follows Figures 1-8 The present invention will be described as follows:

[0031] Example: From the perspective of filter body manufacturing, in existing technologies, the filter body itself needs to be directly machined to form the mounting structure for installing the filter cartridge. However, the filter body itself is a tubular structure, and machining a specific mounting structure inside this tubular structure requires complex processing techniques. For example, specialized processing equipment may be needed to precisely cut and grind the inner wall of the tube to create protrusions, grooves, or other shaped structures that meet installation requirements. This not only places high demands on the precision and performance of the processing equipment but also requires skilled operators to ensure that the dimensions and shape of the mounting structure meet design standards, avoiding situations where a substandard mounting structure prevents the filter cartridge from being installed correctly.

[0032] To solve the above-mentioned technical problems, the following technical solution is provided:

[0033] A Y-shaped filter includes a Y-shaped filter body composed of a tube body 1 and a tube body 2. A filter cylinder 3 is connected inside the tube body 2, and one end of the filter cylinder 3 extends into the tube body 1.

[0034] The tube body 1 is provided with a tubular inlet cylinder 4 with one end open. The bottom surface of the inlet cylinder 4 is inclined. One end of the filter cylinder 3 is perpendicularly connected to the bottom surface of the inlet cylinder 4. The bottom of the inlet cylinder 4 is provided with an opening 5 that communicates with the filter cylinder 3.

[0035] The fluid enters from one end of tube 1, enters the inlet cylinder 4, then enters the filter cylinder 3 through the opening 5, then enters tube 2, and finally exits from the other end of tube 1.

[0036] This invention replaces the original installation structure that was directly machined within the filter body by incorporating a post-installed inlet cylinder 4 within the filter body. The inlet cylinder 4 serves as the connection point to the filter cylinder 3, eliminating the need for a separate inlet structure. The inlet cylinder 4 is an independent tubular component with a sloping bottom surface and an opening 5 at the bottom communicating with the filter cylinder 3. One end of the filter cylinder 3 is perpendicularly aligned with the bottom surface of the inlet cylinder 4. This design eliminates the need to consider the machining of the internal installation structure during the filter body's manufacturing process; only the basic dimensions and performance of the tubular structure need to be ensured. The manufacturing process of the filter body is simplified, eliminating the need for complex machining operations on the internal installation structure, thereby reducing the technical requirements for processing equipment and operators, and significantly reducing the manufacturing difficulty of the filter body.

[0037] Regarding production costs, existing technologies suffer from significant manufacturing difficulties due to the complex processing techniques used in the filter body, which increase processing time and labor costs. Furthermore, the specialized equipment required to meet processing requirements incurs relatively high purchase and maintenance costs. Additionally, substandard installation during processing can lead to increased product scrap rates, further increasing production costs. In this invention, the inlet cylinder 4, as an independent component, has a relatively simple structural design and lower manufacturing difficulty. It can be mass-produced using conventional processing techniques, effectively controlling the manufacturing cost of the inlet cylinder 4. Simultaneously, the simplified processing of the filter body reduces processing time, lowers labor costs, decreases the need for specialized equipment, and consequently reduces the product scrap rate, thereby lowering the overall production cost of the Y-shaped filter.

[0038] From a production efficiency perspective, the complex processing of the filter body in existing technologies prolongs the production cycle, as each filter body requires significant time for processing and inspection of its internal assembly structure. In this invention, however, the processing of the filter body is simplified, increasing the production quantity per unit time. The inlet cylinder 4 can be mass-produced, and its assembly with the filter body is relatively simple. The filter body and inlet cylinder 4 can be produced separately and then assembled. This division of labor improves the overall production pace, significantly increasing the production efficiency of the Y-type filter and better meeting market demand.

[0039] In summary, this utility model, by setting a post-installed liquid inlet cylinder 4 to replace the installation structure inside the filter body, has significant beneficial effects in reducing the manufacturing difficulty of the filter body, reducing production costs, and improving production efficiency, making the Y-shaped filter more advantageous in the manufacturing process.

[0040] The outer wall of the open end of the inlet cylinder 4 is provided with an annular flange 6, and the inner wall of one end of the tube body 1 is formed with a stepped groove 7. The diameter of the stepped groove 7 is equal to the outer diameter of the flange 6, and a locking ring 8 is also included that is threadedly connected to the stepped groove 7. This structural design enables the inlet cylinder 4 to be detachable. When the inlet cylinder 4 needs to be installed, the flange 6 is placed into the stepped groove 7. The size matching between the flange 6 and the stepped groove 7 ensures the initial stability of the inlet cylinder 4 and avoids large shaking or displacement. Then, by rotating the locking ring 8, it is threadedly connected to the stepped groove 7 and gradually tightened, thereby firmly fixing the flange 6 in the stepped groove 7, completing the installation of the inlet cylinder 4. This detachable design brings significant practicality. When the inlet cylinder 4 is worn or damaged, or when its internal parts need to be cleaned and maintained, the inlet cylinder 4 can be removed from the tube body 1 simply by rotating the locking ring 8 in the opposite direction. The operation is simple and quick, without the need for complex disassembly of the filter body, greatly reducing the difficulty of maintenance and replacement. At the same time, it also provides room for adjustment for assembly errors of the liquid inlet cylinder 4 that may occur during the production process. If the assembly does not meet the requirements, it can be easily disassembled and reassembled, which improves the qualification rate of product assembly.

[0041] The flange 6 has a positioning hole 9, and the bottom surface of the stepped groove 7 has a positioning hole 10 corresponding to the positioning hole 9. Positioning pins 11 are connected to the positioning holes 9 and 10. This structure provides precise positioning for the installation of the inlet cylinder 4. When installing the inlet cylinder 4, the positioning hole 9 must be aligned with the positioning hole 10 to allow the positioning pin 11 to be inserted smoothly. This structurally restricts the installation position and angle of the inlet cylinder 4. Since the inlet cylinder 4 needs to maintain a connected state with the filter cylinder 3, the accuracy of its installation position and angle is crucial. If the installation position or angle of the inlet cylinder 4 is offset, the opening 5 at the bottom of the inlet cylinder 4 will not accurately connect with the filter cylinder 3, thus affecting the normal flow of fluid and potentially causing filtration failure. The presence of the positioning pin 11 ensures that the inlet cylinder 4 is placed strictly according to the preset position and angle during installation, maintaining accurate alignment and communication between the opening 5 and the filter cylinder 3. This guarantees the smooth flow of fluid from the inlet cylinder 4 through the opening 5 into the filter cylinder 3, ensuring the stable operation of the Y-shaped filter. Furthermore, this positioning structure reduces adjustment time during installation, improves assembly efficiency, and avoids wasting time due to repeated adjustments to the position of the inlet cylinder 4.

[0042] The locking ring 8 is provided with an operating hole 12. This design facilitates the rotation of the locking ring 8. The operating hole 12 allows tools (such as wrenches, screwdrivers, etc.) to be inserted into it, and force can be applied to the locking ring 8 by the tool, making the rotation operation easier.

[0043] The bottom surface of the inlet cylinder 4 is provided with an insertion groove 13 that is adapted to the filter cylinder 3 for insertion. This structure further enhances the connection stability and docking accuracy between the inlet cylinder 4 and the filter cylinder 3. One end of the filter cylinder 3 needs to be perpendicularly aligned with the bottom surface of the inlet cylinder 4, and the size of the insertion groove 13 is adapted to the end of the filter cylinder 3. When the filter cylinder 3 is inserted into the insertion groove 13, a tight fit is formed between the two. This insertion fit can effectively limit the radial and circumferential displacement of the filter cylinder 3, avoid loosening or misalignment between the filter cylinder 3 and the inlet cylinder 4 due to fluid impact or vibration, and ensure that the opening 5 and the filter cylinder 3 always remain in communication. At the same time, the insertion groove 13 also provides a clear positioning guide for the installation of the filter cylinder 3, enabling the filter cylinder 3 to quickly and accurately dock with the inlet cylinder 4 during the installation process, reducing installation and adjustment time and improving assembly efficiency.

[0044] The filter cartridge 3 is tubular with openings at both ends. A cover 14 is connected to one end of the tube 2, and the other end of the filter cartridge 3 is perpendicularly connected to the cover 14. Several through holes are distributed on the sidewall of the filter cartridge 3. The tubular shape and open-end design allow fluid to enter the filter cartridge 3 from one end and then flow out through the through holes in the sidewall. During this process, impurities in the fluid are trapped inside the filter cartridge 3, thus achieving a filtration effect.

[0045] The cover 14 not only provides a fixed support for the filter cylinder 3, but also seals the end of the tube body 2, preventing fluid from leaking from the end of the tube body 2, and ensuring that the fluid can only enter the space between the tube body 2 and the filter cylinder 3 through the through hole of the filter cylinder 3, and then flow to the other end of the tube body 1 to be discharged.

[0046] The filter cartridge 3 and the inner wall of the tube 2 are spaced apart. This design provides a flow channel for the filtered fluid. When the fluid flows out from the through hole on the side wall of the filter cartridge 3, it enters the spaced area between the filter cartridge 3 and the inner wall of the tube 2, and then flows along this area to the outlet end of the tube 1.

[0047] The outer diameter of the inlet cylinder 4 is equal to the inner diameter of the tube body 1. This ensures that after installation, the outer wall of the inlet cylinder 4 fits tightly against the inner wall of the tube body 1. This dimensional matching eliminates the radial gap between the inlet cylinder 4 and the tube body 1, preventing the fluid from bypassing the gap and ensuring that all fluid entering the tube body 1 enters the inlet cylinder 4 before passing through the opening 5 into the filter cylinder 3. This guarantees the uniqueness of the filtration path and improves filtration efficiency. Furthermore, the tight fit enhances the stability of the inlet cylinder 4 within the tube body 1, reducing swaying caused by fluid impact and lowering structural vibration and noise.

[0048] A sealing gasket is provided between the bottom surfaces of the flange 6 and the stepped groove 7. Its main function is to achieve a seal between the liquid inlet cylinder 4 and the pipe body 1, preventing fluid leakage from the gap between them. When the locking ring 8 presses the flange 6 tightly against the bottom surface of the stepped groove 7, the sealing gasket is compressed and undergoes elastic deformation, filling the microscopic gap between the flange 6 and the bottom surface of the stepped groove 7, forming a reliable sealing interface.

[0049] The inlet cylinder 4 is made of metal. Metal has high structural strength and rigidity, and can withstand the pressure and impact of the fluid inside the tube 1, ensuring that the inlet cylinder 4 is not easily deformed or damaged during long-term use.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
