[0002] A water purification filter generally refers to a filter element of a water purifier. Generally, the filter element is not provided with a water locking structure, and the filter element can only be placed upright in the whole water purifier product. If it is placed in other positions, when replacing the filter element, a large amount of water will leak out. The equipment chassis works in such a humid environment for a long time, and it is very easy to be damaged, reducing the service life of the equipment. Although some other filter elements are provided with a water locking structure, the water locking structure basically adopts a straight-through water locking structure, and the water locking channel is long, which is not conducive to use in some specific environments.

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0015] Please refer to Figure 1-2 , the present utility model provides a technical solution: a T-shaped water locking structure, including a T-shaped main body 1 and a sealing main body 2. The T-shaped main body 1 is arranged in a three-way pipe, and one of the horizontal outlet ends of the horizontal pipe section of the T-shaped main body 1 is closed. The sealing main body 2 is arranged in a straight-through pipe, and the sealing main body 2 is slidably installed in the horizontal pipe of the T-shaped main body 1 and can extend out of the unclosed outlet end of the horizontal pipe section of the T-shaped main body 1. Sealing rings 3 that are in sealing contact with the inner wall of the horizontal pipe section of the T-shaped main body 1 are respectively arranged around both ends of the outer side of the sealing main body 2. A spring 6 is sleeved on the outer side of the sealing main body 2. One end of the spring 6 abuts against the unclosed end outlet of the T-shaped main body 1, and the other end of the spring 6 abuts against the sealing main body 2.
[0016] An annular groove 4 is arranged at the sealing ring 3 at one end of the sealing main body 2 close to the closed outlet end of the T-shaped main body 1. The sealing ring 3 is sleeved in the annular groove 4, and the sealing ring 3 is in sliding seal with the inner wall of the T-shaped main body 1.
[0017] A second annular groove 5 is provided at the inner wall of the T-shaped body 1 near the sealing ring 3 at the unclosed opening end. The sealing ring 3 is arranged in the second annular groove 5, and the sealing ring 3 is in sliding seal with the outer wall of the sealing body 2.
[0018] By providing the first annular groove 4 and the second annular groove 5, the two sealing rings 3 can be limited, so as to avoid the situation that the two sealing rings 3 deviate from the preset position when the sealing body 2 slides left and right.
[0019] An annular protrusion 7 is provided at one end of the sealing body 2 that abuts against the spring 6, and the spring 6 abuts against the annular protrusion 7.
[0020] One end of the T-shaped body 1 that abuts against the spring 6 is provided with a stepped hole 8. The aperture of the unclosed outlet end of the T-shaped body 1 is smaller than the aperture of the pipeline inside the T-shaped body 1. The spring 6 is placed in the pipeline inside the T-shaped body 1 and abuts against the stepped hole 8 end.
[0021] Through this technical solution, when the spring 6 rebounds, the left sealing ring 3 forms a seal with the inner surface of the T-shaped body 1, and the left sealing ring 3 forms a seal with the outer surface of the sealing body 2; at the same time, the right sealing ring 3 forms a seal with the inner surface of the T-shaped body 1, and the right sealing ring 3 forms a seal with the outer surface of the sealing body 2. Water cannot enter the horizontal cavity of the T-shaped body 1 after passing through the vertical cavity of the T-shaped body 1;
[0022] When the spring 6 is compressed, the left sealing ring 3 is partially separated from the inner surface of the T-shaped body 1. Water passes through the vertical cavity of the T-shaped body 1 and then enters the horizontal cavity, and then enters the cavity of the sealing body 2 and flows out.
