The first connector has a first square tube portion, and the second connector has a second square tube portion sleeved on the first square tube portion. A fixing assembly is provided between the first and second square tube portions, and a sealing assembly is provided between the first and second square tube portions. A square hole is provided on the upper surface of the first square tube portion, and insertion grooves communicating with the square hole are provided on the inner walls of the front and rear sides of the first square tube portion. The filter assembly includes components that insert through the square hole and are fitted with… The device comprises a square frame fitted within a slot, a metal filter screen disposed at the end of the square frame away from the first square tube, and an elastic element disposed on the square frame to drive the square frame to protrude upward through the square hole; a guide structure is provided between the upper surface of the square frame and the second square tube, which, during the movement of the second square tube toward the direction closer to the first connector, overcomes the action of the elastic element to prevent the square frame from protruding through the square hole; a limiting component is provided between the first connector and the second connector to adjust the movement range of the second square tube, which, when the second square tube moves to its limit away from the first connector, does not interfere with the assembly and disassembly of the filter assembly.

[0005] By adopting the above technical solution, the square frame and the metal filter screen first form a cylindrical filter structure, which can filter and store impurities in the medium. When it is necessary to clean the filter assembly, the fixing component is first released, so that the second square tube moves to its limit away from the first connector. At this time, the square hole is exposed. The filter assembly protrudes from the square hole under the reset action of the elastic element, and the filter assembly can be directly removed. After cleaning, the filter assembly is reinstalled, and the second square tube is reset. The fixing component fixes the first square tube and the second square tube. The setting of the limiting component can prevent the first square tube and the second square tube from completely separating. Finally, the function of cleaning the filter assembly is achieved.

[0021] Example: A copper connector with a cleanable function, such as Figure 1 and Figure 2 As shown, it includes a first connector 1, a second connector 2 connected to the first connector 1, and a filter assembly 3.

[0022] like Figure 1 and Figure 2 As shown, the first connector 1 is provided with a first square tube 1-1, the second connector 2 is provided with a second square tube 2-1 sleeved on the first square tube 1-1, a fixing component 4 is provided between the first square tube 1-1 and the second square tube 2-1, and a sealing component 5 is provided between the first square tube 1-1 and the second square tube 2-1.

[0023] like Figures 1 to 3As shown, a square hole 1-2 is provided on the upper surface of the first square tube 1-1, and insertion grooves 1-3 communicating with the square hole 1-2 are provided on the inner walls of the front and rear sides of the first square tube 1-1. The filter assembly 3 includes a square frame 3-1 inserted through the square hole 1-2 and fitted into the insertion groove 1-3, a metal filter screen 3-2 disposed at one end of the square frame 3-1 away from the first square tube 1-1, and an elastic member 3-3 disposed on the square frame 3-1 for driving the square frame 3-1 to protrude upward from the square hole 1-2. A guide structure 6 is provided between the upper surface of the square frame 3-1 and the second square tube 2-1. During the movement of the second square tube 2-1 toward the direction closer to the first connector 1, the guide structure 6 overcomes the action of the elastic member 3-3 so that the square frame 3-1 does not protrude from the square hole 1-2. A limiting component 7 for adjusting the movement range of the second square tube 2-1 is provided between the first connector 1 and the second connector 2. When the second square tube 2-1 moves to its limit in a direction away from the first connector 1, the second square tube 2-1 does not interfere with the disassembly and assembly of the filter assembly 3.

[0024] like Figure 1 and Figure 2 As shown, the first square tube 1-1 has limiting holes 1-4 on its upper and lower sides. The fixing component 4 includes two fixing bolts 4-1 threadedly connected to the second square tube 2-1 and embedded in the limiting holes 1-4. The sealing component 5 includes two rubber sealing rings 5-1 embedded in the periphery of the first square tube 1-1, with the two rubber sealing rings 5-1 located at both ends of the square hole 1-2. The lower surface of the square frame 3-1 is provided with a receiving groove 3-4. The elastic element 3-3 is a metal spring sheet with one end fixed in the receiving groove 3-4 and which is housed in the receiving groove 3-4 after deformation under force. The guiding structure 6 includes a first guiding slope 6-1 located on the upper surface of the square frame 3-1 near the corner of the second connector 2, and a second guiding slope 6-2 located on the end of the second square tube 2-1 near the first connector 1 and mating with the first guiding slope 6-1 during movement (the mark indicates the edge of the second guiding slope 6-2). The limiting assembly 7 includes a limiting support plate 7-1 with an oblong hole disposed on the first connector 1, and a limiting bolt 7-2 threadedly connected to the second square tube 2-1 after passing through the oblong hole.

[0025] Implementation effect: First, the square frame 3-1 and the metal filter screen 3-2 form a cylindrical filter structure, which can filter and store impurities in the medium. When it is necessary to clean the filter assembly 3, the fixing component 4 is first released, so that the second square tube 2-1 moves to its limit away from the first connector 1. At this time, the square hole 1-2 is exposed. The filter assembly 3 protrudes from the square hole 1-2 under the reset action of the elastic element 3-3, and the filter assembly 3 can be directly removed. After cleaning, the filter assembly 3 is reinstalled, and the second square tube 2-1 is reset. The fixing component 4 fixes the first square tube 1-1 and the second square tube 2-1. The setting of the limiting component 7 can prevent the first square tube 1-1 and the second square tube 2-1 from completely separating. Finally, the function of cleaning the filter assembly 3 is achieved.

[0026] The fixing component 4 includes two fixing bolts 4-1 threaded onto the second square tube section 2-1 and embedded in the limiting hole 1-4, thereby fixing the first square tube section 1-1 and the second square tube section 2-1. Two rubber sealing rings 5-1 are provided, with the two rubber sealing rings 5-1 located at both ends of the square hole 1-2, thereby sealing the connection between the first square tube section 1-1 and the second square tube section 2-1. The elastic element 3-3 is a metal spring sheet with one end fixed in the receiving groove 3-4 and which, after deformation under force, is housed within the receiving groove 3-4. Thus, after the square hole 1-2 is exposed, the metal spring sheet, upon resetting, can drive the square frame 3-1 to protrude upwards from the square hole 1-2. The first guide slope 6-1 and the second guide slope 6-2 allow the filter component 3 to be directly guided into the square hole 1-2 for installation during the installation of the second square tube section 2-1, facilitating installation. The limiting assembly 7 includes a limiting support plate 7-1 with an oblong hole disposed on the first connector 1, and a limiting bolt 7-2 threaded through the oblong hole and connected to the second square tube 2-1, thereby preventing the first square tube 1-1 and the second square tube 2-1 from completely separating.
