[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit 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.

[0017] Example 1 Please see Figures 1-5 This utility model provides a technical solution: it includes a filter body 1, with several locking blocks 2 fixedly connected to the outer edge of the filter body 1. A round cover 4 is provided at both the left and right ends of the filter body 1. A fixing block 3, adapted to the locking block 2, is fixedly installed at the outer end of the round cover 4. When the round cover 4 is attached to the port of the filter body 1, the locking block 2 and the fixing block 3 form a locking engagement. A through hole 8 is provided on the inner wall of the fixing block 3. The locking block 2 adopts an elastic locking plate structure, with an upwardly protruding limiting block at the end away from the filter body 1. The outer wall of the locking block 2 precisely fits the inner wall of the through hole 8, forming a stable locking connection. The limiting block prevents the locking block 2 from falling out of the through hole 8, thereby achieving rapid assembly and fixing of the filter body 1 and the round cover 4.

[0018] First, hold the corresponding round caps 4 at the left and right ends and align the fixing block 3 at the outer end of the round cap 4 with the locking block 2. Then, push the round cap 4 closer to the port of the filter body 1, allowing the locking block 2 to slide along the through hole 8 on the inner wall of the fixing block 3. Since the locking block 2 is an elastic locking plate structure, it will naturally adapt to the through hole 8 during the sliding process. When the round cap 4 is attached to the port of the filter body 1, the outer wall of the locking block 2 and the inner wall of the through hole 8 are precisely attached to form a locking connection. The upward protruding limiting block at its end will be locked on the outside of the through hole 8 to prevent the locking block 2 from falling off, thus completing the quick assembly and fixing of the filter body 1 and the round cap 4.

[0019] Example 2 Based on Embodiment 1, the inner wall of the round cover 4 facing the filter body 1 has an annular groove 9. The size of the groove 9 is adapted to the sealing ring 10. The sealing ring 10 is embedded in the groove 9 and forms a sliding connection, which can move smoothly along the circumference of the groove 9 to ensure the accurate position of the sealing ring 10 during assembly. On the end face of the filter body 1 near the round cover 4, there is an annular groove 11 corresponding to the groove 9. When the filter body 1 and the round cover 4 are assembled in place by the engaging structure of the locking block 2 and the fixing block 3, the sealing ring 10 is precisely embedded in the groove 11. The cooperation of the groove 9 and the groove 11 achieves dual positioning and ensures the stability of the sealing effect. The indicator strip 6 on the outer wall of the filter body 1 extends axially to clearly indicate the installation orientation and avoid assembly direction deviation. The pressure gauge 7 on the top is connected to the internal flow channel and can monitor the pressure in real time to facilitate the monitoring of the equipment status.

[0020] Embed the sealing ring 10 into the slot 9 and push it to slide smoothly along the circumference of the slot 9 to the appropriate position, ensuring a good fit. Then, slide the fixing block 3 along the outer wall of the block 2 according to the corresponding position. When the block 2 engages with the through hole 8, the sealing ring 10 is precisely embedded in the slot 11. The cooperation between the slot 9 and the slot 11 completes the double positioning and achieves sealed assembly. According to the markings on the indicator strip 6 extending axially along the outer wall of the filter body 1, the installation orientation of the filter is clear, ensuring that it is connected to other components in the correct direction to avoid deviation in the assembly direction. After assembly, the pressure gauge 7 on the top is connected to the internal flow channel and can monitor the pressure in real time. The operator can observe the equipment status by observing the pressure gauge 7 to ensure the normal operation of the filtration process.

[0021] Example 3 Based on Embodiment 2, a filter element 12 is provided on the inner wall of the filter body 1, and the two form a sliding connection. The filter element 12 can move smoothly along the axial direction of the inner wall of the filter body 1, which is convenient for quick disassembly and replacement. A fixing ring 13 is fixedly connected to one end of the filter element 12. The fixing ring 13 and the end of the filter element 12 form an integral structure, which plays a role in axial positioning and support of the filter element 12. A filter screen 15 is provided inside the filter element 12. The filter screen 15 extends along the axial direction of the filter element 12 to form the core part of the filtration channel, which is used to achieve precise filtration of fluid. When the filter element 12 is installed into the filter body 1, the fixing ring 13 at one end fits tightly against the left side of the inner wall of the filter body 1, and the handle 14 at the other end abuts against the right side of the inner wall of the filter body 1. Through the limiting cooperation at both ends, the filter element 12 is accurately positioned in the filter body 1, avoiding displacement due to fluid impact during filtration. The outer wall of the fixing ring 13 is fixedly connected to the handle 14. The handle 14 provides a convenient force application point for picking up and putting down the filter element 12, further improving the efficiency of assembly and maintenance.

[0022] When assembling and replacing the filter element, first hold the handle 14 on the outer wall of the fixing ring 13, align the filter element 12 with the inner wall of the filter body 1, and move the filter element 12 along the inner wall of the filter body 1. During the process, the filter element 12 is axially positioned and supported by the integral structure formed by the fixing ring 13 and the filter element 12, thus completing the assembly of the filter element 12. When disassembling, hold the handle 14 in the same way and pull the filter element 12 out smoothly along the inner wall of the filter body 1, so as to realize the quick disassembly and replacement of the filter element 12.

[0023] In actual use, first check the annular groove 9 on the inner wall of the round cover 4, insert the sealing ring 10 and slide it circumferentially to the appropriate position. Then, hold the handle 14 on the outer wall of the fixing ring 13, align the filter element 12 with the inner wall of the filter body 1, and push it in smoothly along the axial direction. With the help of the fixing ring 13, ensure that the filter element 12 is in the correct position. Then, hold the round cover 4 and align the fixing block 3 with the locking block 2 on the outer wall of the filter body 1. Slide the fixing block 3 along the locking block 2. When the locking block 2 engages with the through hole 8, the sealing ring 10 is just inserted into the groove 11 on the end face of the filter body 1, completing the overall assembly. When disassembling, slide the fixing block 3 in the opposite direction to separate the round cover 4, and then pull out the filter element 12 through the handle 14.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
