[0026] In this embodiment, through the arrangement of the pipe body 1 and the connecting pipe 2, when the corrugated pipe is in use, the connecting pipe 2 at one end can be connected to the equipment that needs drainage, and the connecting pipe 2 at the other end can be inserted into the floor drain and connected to the sewer pipe for drainage. The connecting pipe 2 only needs to be socketed with the equipment and inserted into the drain outlet, and the length is set to be short. In actual use, the length of the pipe body 1 is much longer than the length of the connecting pipe 2.

[0027] In this embodiment, by setting the fixing sleeve 3 and the filter plate 4, the fixing sleeve 3 is fixedly connected to the inner wall of the connecting pipe 2 and the portion where the fixing sleeve 3 and the connecting pipe 2 are connected is watertight, and the filter plate 4 is detachably connected to the fixing sleeve 3. When the device is used on a washing machine, the connecting pipe 2 with the filter plate 4 installed at one end can be connected to the washing machine. When the washing machine is draining water, the water flows through the connecting pipe 2 and needs to flow into the pipe body 1 through the filter plate 4. Since the washing machine will produce lint or other dirt when washing clothes, when the washing machine is used for a long time, some lint or dirt may accumulate on the inner wall of the pipe body 1 connected to the washing machine, resulting in poor drainage, and it is difficult to clean the inner wall of the pipe body 1. By setting the filter plate 4, the filter plate 4 can block the lint and part of the dirt in the connecting pipe 2. When cleaning the lint and dirt, it is only necessary to remove the connecting pipe 2 at one end connected to the washing machine, clean the connecting pipe 2, and remove the filter plate 4 to clean the filter plate 4 at the same time, which better solves the problem of difficult cleaning of the inner wall of the pipe body 1.

[0028] In this embodiment, by arranging the mounting plate 5, the hole 6, the mounting tube 7 and the plug 8, the mounting plate 5 is fixedly connected to the inner wall of the connecting tube 2 and the connection is watertight, the mounting tube 7 is fixedly connected to the mounting plate 5 and the connection is watertight, when this kind of corrugated tube is used on a washing machine, the connecting tube 2 at one end thereof equipped with the plug 8 can be inserted into a floor drain for drainage, when the tube body 1 is draining, the pressure generated by the water flow can push the plug 8 to separate from the hole 6, so that the water flow can flow into the mounting tube 7 through the hole 6 and be discharged into the floor drain through the connecting tube 2, when the tube body 1 stops draining and is not in use, the plug 8 fits with the hole 6 to seal the tube body 1, which can prevent mosquitoes and bacteria in the sewer pipe from entering the washing machine through the tube body 1 and causing pollution.

[0029] See also Figure 1-Figure 4 In this embodiment, the driving assembly includes a mounting cap 100 disposed at the other end of the mounting tube 7 , and a first spring 101 is provided between the mounting cap 100 and the plug 8 for pushing the plug 8 to fit the hole 6 .

[0030] In this embodiment, by setting the mounting cap 100 and the first spring 101, the mounting cap 100 can be connected to the mounting tube 7 by threads, and the disassembly and assembly of the mounting cap 100 is preferably realized so as to install the components in the mounting tube 7. When the tube body 1 is not draining water, the first spring 101 can push the plug 8 to seal the hole 6. When the tube body 1 is draining water, the pressure generated by the water flow is greater than the thrust of the spring, which can push the plug 8 to compress the spring and separate the plug 8 from the hole 6, thereby opening the hole 6 for drainage.

[0031] See also Figure 1-Figure 4 In this embodiment, a plurality of slots 102 communicating with the holes 6 are formed on the surface of the mounting tube 7 , and a circular hole 103 communicating with the slots 102 is formed on the mounting cap 100 .

[0032] In this embodiment, there is a certain gap between the mounting tube 7 and the connecting tube 2. By setting the notch 102 and the circular hole 103, when the hole 6 is opened for drainage, water can flow into the connecting tube 2 through the notch 102, and can also flow into the connecting tube 2 through the circular hole 103, thereby preferably accelerating the flow of water and discharging the water more quickly.

[0039] Working principle: When the corrugated pipe is in use, the connecting pipe 2 with a filter plate 4 at one end can be connected to a washing machine or other equipment, and then the connecting pipe 2 with a plug 8 at one end can be connected to a floor drain or other drainage point. When the pipeline is draining, the pressure generated by the water flow can push the plug 8 to separate from the hole 6, so that the water flow can flow into the installation pipe 7 through the hole 6 and be discharged into other drainage points of the floor drain through the connecting pipe 2. When the pipe body 1 stops draining and is not in use, the first spring 101 pushes the plug 8 to fit with the hole 6 to seal the pipe body 1, which can prevent mosquitoes and bacteria in the sewer pipe from entering the washing machine or other equipment through the pipe body 1 to cause pollution.
