[0017] As Figures 1 to 4 shown, the present invention provides a filter plug for a low-temperature water pool, including: a plug body 1, a central column 8, and a pressing plate 5; the central column 8 is fixed inside the plug body 1, a threaded hole 11 is opened at one end of the central column 8 away from the plug body 1, a screw rod 9 is connected in the threaded hole 11, a top plate 4 is connected to the screw rod 9, one side of the top plate 4 is in contact with the central column 8, a first elastic member 10 is connected to the side of the top plate 4 close to the plug body 1, and one end of the first elastic member 10 away from the top plate 4 is connected to the pressing plate 5, and the pressing plate 5 is sleeved on the central column 8; sliding grooves 12 are opened on both sides of the central column 8, second elastic members 13 are connected inside the sliding grooves 12, one end of the second elastic member 13 is connected to a slider 14, the slider 14 is slidably connected to the inner wall of the sliding groove 12, a bearing plate 15 is fixed on the side of the slider 14 away from the central column 8, and the sides of the bearing plate 15 are in contact with the inner wall of the plug body 1, and the pressing plate 5 corresponds to the bearing plate 15; a plurality of fixing blocks 6 are connected to the side of the pressing plate 5 away from the bearing plate 15, and a handle 7 is rotatably connected to one end of the fixing block 6 away from the pressing plate 5.
[0018] Among them, a plurality of sleeve plates 2 are fixed on the side of the plug body 1, a gasket 3 is connected between the sleeve plates 2, and the gasket 3 is made of rubber material; to improve the sealing performance between both sides of the plug body 1 and the water pool.
[0019] Among them, filter holes are processed on the side of the plug body 1, and the height of the central column 8 is greater than the height of the plug body 1; to facilitate the low-temperature water to enter the plug body 1 from below the pressing plate 5.
[0020] Among them, the radius of the pressing plate 5 is equal to the radius of the bearing plate 15, and the radius of the top plate 4 is smaller than the radius of the pressing plate 5; to facilitate restricting foreign objects between the pressing plate 5 and the bearing plate 15.

[0022] Working principle and usage process of the present utility model: When the net plug body 1 is in the low-temperature water tank, the gasket 3 arranged between the sleeve plates 2 can play a sealing role to prevent the low-temperature water from flowing out from the side of the net plug body 1. The low-temperature water flows into the bearing plate 15 through the gap between the pressing plate 5 and the net plug body 1. Foreign matters will be intercepted by the bearing plate 15, while the low-temperature water will flow out from the side of the net plug body 1. When the foreign matters accumulate inside the net plug body 1 to a certain extent, people can rotate the handle 7 to an appropriate angle through the fixing block 6, and then pull out the entire net plug body 1, and press the pressing plate 5 downward with fingers. At this time, the gap between the pressing plate 5 and the net plug body 1 begins to close, and the foreign matters will remain between the bearing plate 15 and the pressing plate 5. The low-temperature water will flow out from the filter holes on the side of the net plug body 1 along with the pressure applied by people on the pressing plate 5. Finally, people separate the screw rod 9 from the threaded hole 11, so that the top plate 4 drives the pressing plate 5 to separate from the net plug body 1, and the foreign matters can be poured out. The first elastic member 10 and the second elastic member 13 will make the pressing plate 5 and the slider 14 automatically reset, saving people's physical consumption.
