[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0025] like Figures 1-3 As shown, an oxygen cylinder cap includes a cap 1, a filter element 2, and a sealing ring 10. The filter element 2 and the cap 1 are detachably connected. A connecting thread 4 is provided on the inner wall of the cap 1. The cap 1 has a downwardly extending connecting tube 3 for installing the filter element 2. The connecting tube 3 is a circular tube structure with a smooth outer wall. The maximum outer diameter of the connecting tube 3 is smaller than the inner diameter of the mouth of a mineral water bottle. The upper end of the connecting tube 3 is connected to the inner top wall of the cap. An oxygen outlet 6 communicating with the interior of the connecting tube 3 is provided on the top wall of the cap 1. There is a certain distance between the connecting tube 3 and the connecting thread 4. The connecting thread 4 is compatible with the thread of a commercially available mineral water bottle mouth, thus allowing the cap 1 to be installed on a mineral water bottle. Figure 4The sealing ring 10 is annular, made of rubber material, detachably arranged on the inner top wall of the bottle cap 1 between the connecting pipe portion 3 and the connecting thread 4, seals the bottle mouth of the mineral water bottle when the bottle cap 1 is installed on the mineral water bottle, and prevents air leakage.

[0026] As shown in Figure 2 and Figure 3 The bottle cap 1 is made of plastic material and is integrally formed, and the outer cylindrical wall of the bottle cap 1 is provided with anti-skid structures 11 which are anti-skid vertical lines uniformly distributed along the circumferential direction of the bottle cap 1.

[0027] As shown in Figure 1 The filter element 2 is an open-top cylinder, and the inner cavity thereof is a containing cavity for storing clean water. The filter element 2 is made of transparent silica gel material, so that the user can see the water quality and bubble condition in the filter element 2. The upper end opening of the filter element 2 is sleeved on the outside of the connecting pipe portion 3, and in a natural state, the hole diameter of the upper end opening of the filter element 2 is smaller than the outer diameter of the connecting pipe portion 3, so that when the filter element 2 is sleeved on the connecting pipe portion 3, the connecting pipe portion 3 can be clamped tightly to form a sealed structure. The bottom of the filter element 2 is provided with a one-way valve 5 communicating with the containing cavity, the flow direction of the one-way valve 5 is from the outside to the containing cavity, and the one-way valve 5 can prevent the clean water in the filter element 2 from leaking out.

[0028] The use method of the utility model is as follows: the A material and the B material are put into the mineral water bottle, and a certain amount of clean water is added into the mineral water bottle. A certain amount of clean water is added into the filter element 2, and then the filter element 2 is sleeved on the connecting pipe portion 3. Then the filter element 2 is inserted into the mineral water bottle, and the bottle cap 1 is tightly screwed on the bottle mouth of the mineral water bottle, as shown in Figure 4 Finally, the mineral water bottle is shaken appropriately, and the oxygen inhalation tube is inserted into the insertion groove 8. The A material, the B material and water react to produce oxygen, when the air pressure in the mineral water bottle increases to a certain extent, the generated oxygen enters the filter element 2 through the one-way valve 5, and then enters the oxygen inhalation tube through the oxygen outlet 6 after being filtered by the clean water in the filter element 2.

[0029] As described above, the utility model is used in combination with the mineral water bottle on the market, which can achieve the use effect of the oxygen cylinder on the market, and the mineral water bottle is very easy to obtain. Therefore, when people travel to highland areas and conduct scientific investigations, they only need to carry the oxygen cylinder bottle cap provided by the utility model, without carrying oxygen cylinders, so that carrying is more convenient.

[0030] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
