[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0025] like Figure 1 and Figure 2 and Figure 3 As shown, a one-way valve with an easily reset valve core includes a valve body 1, a valve core 2, and an elastic element 3. A through hole 10 is provided in the valve body 1. A first limiting ring 11 and a second limiting ring 12 are respectively provided at both ends of the through hole 10. The first limiting ring 11 is provided at the outlet end of the through hole 10, and the second limiting ring 12 is provided at the inlet end of the through hole 10. Liquid enters the through hole 10 from the second limiting ring 12, and then the liquid flows out from the first limiting ring 11.
[0026] The valve core 2 is slidably disposed in the through hole 10. The first limiting ring 11 and the second limiting ring 12 are located on the front and rear sides of the valve core 2, respectively. The end of the valve core 2 is pressed against the second limiting ring 12, which can prevent liquid from entering the through hole 10 from the second limiting ring 12.
[0027] A blocking ring 13 is provided inside the through hole 10. The blocking ring 13 has a liquid outlet hole 14. A cavity 21 is provided inside the valve core 2. The cavity 21 is isolated from the outside of the valve core 2.
[0028] The elastic element 3 abuts against the cover plate 22 and the blocking ring 13 at both ends. When the valve core 2 is squeezed from the second limiting ring 12, the valve core 2 will be subjected to pressure greater than the elastic force of the elastic element 3. The valve core 2 will squeeze the elastic element 3, and the elastic element 3 will press against the blocking ring 13. At this time, the liquid will enter the through hole 10 from the second limiting ring 12. The liquid will surround the valve core 2, and then the liquid will flow out from the liquid outlet hole 14. The elastic element 3 is a spring.
[0029] Because the cavity 21 is empty, the density of the valve core 2 is equal to the density of the liquid, meaning the specific gravity of the valve core 2 with the cavity is equal to the specific gravity of the liquid. Therefore, the valve core 2 will float in the liquid, but it will not float upwards or sink to the bottom of the through hole 10. When the valve core 2 is reduced by the liquid compression, and the pressure on the valve core 2 is less than the elastic force of the elastic element 3, the valve core 2 will retract and reset under the action of the elastic element 3. The valve core 2 will be completely within the second limiting ring 12, preventing the liquid from entering the through hole 10 from the second limiting ring 12. When the valve core 2 retracts, it directly aligns with the inside of the second limiting ring 12, keeping the inside of the second limiting ring 12 in a sealed state.
[0030] In other embodiments, the specific gravity of the valve core 2 can be slightly greater or slightly less than the density of the liquid.
[0031] A ring groove 23 is also provided on the inner wall of the valve body 1. The blocking ring 13 is disposed in the ring groove 23. The first limiting ring 11 wraps around the blocking ring 13, and the elastic member 3 abuts against the blocking ring 13.
[0032] The first limiting ring 11 is located on the sliding path of the blocking ring 13. The ring groove 23 is set to fit the first limiting ring 11. The inner side of the first limiting ring 11 has a concave surface. The farthest sliding distance is when it abuts against the inner side of the first limiting ring 11.
[0033] A hollow column 15 with a hollow core is provided inside the liquid outlet 14. Multiple connecting rods 16 are provided on the inner circumference of the blocking ring 13. The multiple connecting rods 16 are connected around the outer circumference of the hollow column 15. The cover plate 22 is in the extension direction of the hollow column 15. When the valve core 2 moves toward the first limiting ring 11, the cover plate 22 can press against the hollow column 15. The hollow column 15 has a limiting effect on the cover plate 22. There is a gap between adjacent connecting rods 16, and liquid can flow out from the adjacent connecting rods 16.
[0034] The elastic element 3 is fitted onto the hollow column 15, so that the elastic element 3 is not easy to bend when subjected to force, and the elastic element 3 is not easy to fall off.
[0035] A cover plate 22 is provided at the opening end of the cavity 21, and the cover plate 22 covers the cavity 21. An annular flange 24 is provided on the outer periphery of the opening end of the cavity 21. When the valve core 2 moves toward the first limiting ring 11, the annular flange 24 is used to restrict the elastic element 3 and compress the elastic element 3 inside the annular flange 24. The size of the annular flange 24 is smaller than the outer diameter of the valve core 2, so there is a distance between the valve core 2 and the multiple connecting rods 16, which can be used for liquid flow.
[0036] The cavity 21 is either a vacuum or filled with gas, and can also be filled with low-density materials.
[0037] The inner wall of the second limiting ring 12 gradually narrows and extends outward. The valve core 2 has a first end and a second end. The first end of the valve core 2 is close to the first limiting ring 11. The outer wall of the second end of the valve core 2 gradually narrows and extends outward. The second end of the valve core 2 is located inside the second limiting ring 12. In the initial state, the second end of the valve core 2 seals the second limiting ring 12, preventing liquid from entering the through hole 10 from the second limiting ring 12. The shape and size of the second end of the valve core 2 match the internal shape and size of the second limiting ring 12.
[0038] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
