[0022] See also Figure 1-5 The utility model provides a technical solution: a central air-conditioning drainage pipe structure, including a pipe body 1, a pipe body 2 and a maintenance device 4, the pipe body 2 is arranged at one end of the pipe body 1, a water inlet pipe 3 is arranged on the surface of the pipe body 1, and the maintenance device 4 is arranged between the pipe body 1 and the pipe body 2.

[0023] The specific configuration and functions of the maintenance device 4 and the auxiliary component 42 will be described in detail below.

[0024] Specifically, the maintenance device 4 includes a maintenance tube 41, which is arranged between the tube body 1 and the tube body 2. Two connecting ends 43 are slidably connected on both sides of the maintenance tube 41. The surfaces of the tube body 1 and the tube body 2 are provided with threaded grooves, and the connecting ends 43 are plugged into the inner walls of the threaded grooves. The tube body 1 is provided with a filter element 410, and the inner wall of the filter element 410 is rotatably connected to a pull rod 45.

[0025] In this embodiment: the maintenance tube 41 can be installed between the tube body 1 and the tube body 2 through the connecting end 43. When the water inlet pipe 3 supplies water to the tube body 1, the impurities in the water can be directly filtered by the filter element 410 in the maintenance tube 41. The pull rod 45 can take out the filter element 410, thereby cleaning the intercepted impurities and reducing the problem that the water in the impurity water flows everywhere, making it inconvenient for subsequent cleaning.

[0026] Specifically, two sliders 49 are fixedly connected to the surface of the filter element 410, and two slide grooves 48 are provided on the inner wall of the maintenance tube 41. The sliders 49 are slidably connected to the inner walls of the slide grooves 48. The sliders 49 on the filter element 410 can cooperate with the slide grooves 48 for guidance, thereby improving the stability of the installation of the filter element 410.

[0027] Specifically, both ends of the maintenance pipe 41 are respectively fixedly connected with protection pads 44 , and a groove having the same size as the slide groove 48 is formed on the surface of one of the protection pads 44 .

[0028] In this embodiment, after the connection end 43 is connected to the threaded grooves on the surface of the tube body 1 and the tube body 2, the two protection pads 44 can respectively abut against one end of the tube body 1 and the tube body 2, thereby preventing leakage.

[0029] Specifically, three connecting rods 46 are fixedly connected to the surface of the pull rod 45, and a cleaning rod 47 is fixedly connected to one end of the connecting rod 46. The pull rod 45 can drive the connecting rod 46 and the cleaning rod 47 to rotate, so that the cleaning rod 47 can clean the inner wall of the maintenance tube 41, making it easier for the subsequent filter element 410 to push out impurities.

[0030] Specifically, the surfaces of the tube body 1 and the tube body 2 are provided with an auxiliary component 42, and the auxiliary component 42 includes a fixed seat 421. There are two fixed seats 421, and the two fixed seats 421 are respectively fixedly connected to the surfaces of the tube body 1 and the tube body 2, and a sliding groove is opened on one side surface of the fixed seat 421, and a sliding cover 422 is slidably connected to the inner wall of the sliding groove.

[0031] In this embodiment, the sliding cover 422 can slide in the fixing seat 421. When the maintenance tube 41 is removed, the sliding cover 422 can be slid down, and the sliding cover 422 shields and protects one end of the tube body 1 and the tube body 2 2.

[0032] Specifically, a counterweight block 423 is fixedly connected to one side surface of the sliding cover 422 , and the counterweight block 423 allows the sliding cover 422 to move freely downward.

[0033] Working principle: When the equipment is in use, the central air conditioner discharges condensed water into the pipe body 1 and the pipe body 2 2 through the water inlet pipe 3 for drainage. By setting the maintenance device 4, when the water inlet pipe 3 discharges water into the pipe body 1, the condensed water will directly enter the maintenance pipe 41. The filter element 410 in the maintenance pipe 41 can filter impurities and intercept the impurities in the maintenance device 4. The maintenance pipe 41 is subsequently disassembled for cleaning. When disassembling, the two threaded ends are rotated. After the threaded ends are moved out of the threaded grooves on the surfaces of the pipe body 1 and the pipe body 2, the maintenance pipe 41 can be disassembled. When the maintenance pipe 41 is disassembled, the counterweight block 423 can drive the sliding cover 422 to slide in the fixing seat 421, thereby balancing the pipe body 1 and the pipe body 2. 2 is blocked. When cleaning, the pull rod 45 is rotated to raise and drive the cleaning rod 47 to rotate to clean the inner wall of the maintenance tube 41. After cleaning, the pull rod 45 is pulled, and the pull rod 45 drives the filter 410 to move out. The filter 410 takes out the impurities and can be cleaned. By setting the maintenance device 4, it is convenient to maintain and clean the central air-conditioning drain pipe, which can effectively reduce the existing central air-conditioning drain pipe. When draining, due to impurities in the condensed water, the impurities will flow with the condensed water and assist in various places on the inner wall of the drain pipe, resulting in inconvenience in subsequent cleaning. Impurities will accumulate for a long time to cause blockage and affect normal drainage, thereby improving the overall practicality of the equipment.
