[0002] Oxygen production cups generally use the reaction principle of mixing oxygen production agent, catalyst and water to obtain a large amount of oxygen. At present, this method is also commonly used in oxygen production cups in China.
[0003] At present, oxygen production cups in China generally use the method of preparing on site temporarily and then producing oxygen. Oxygen production agent and catalyst are prepared in the reaction cavity below in advance, water is added to the reaction cavity when oxygen production is needed, and sufficient water is added to the filtering cavity, the oxygen production agent, catalyst and water in the reaction cavity are mixed, impure oxygen is produced, the oxygen rises, and the oxygen is filtered through water in the filtering cavity above, and the user obtains filtered clean oxygen through the oxygen inhalation tube above the filtering cavity.
[0004] This kind of prior art has certain defects. For example, in addition to adding water in the reaction cavity, sufficient water needs to be added to the filtering cavity to filter the oxygen produced, which is relatively cumbersome and brings inconvenience to the user. Moreover, when the user is in an emergency, it is often not possible to add sufficient water to the filtering cavity, so impure oxygen that has not been filtered is obtained. If sufficient water is added to the filtering cavity in advance to avoid this situation, the water in the filtering cavity will often leak into the reaction cavity because the filtering cavity is located above the reaction cavity, so the water will mix with the oxygen production agent and catalyst, even if the user does not want to produce oxygen at this time, the reaction will start automatically in advance, resulting in waste. In addition, the filtering effect of water is often not ideal, resulting in some impurities still existing in the oxygen after filtration. In addition, the use of the filtering cavity increases the manufacturing cost. CONTENT OF THE UTILITY MODEL
[0005] In order to overcome the above-mentioned defects in the prior art, the utility model provides an oxygen production cup which is composed of a main body and a cover, the main body is composed of a bottle body and a bottle mouth, the bottle body is a hollow cylinder, the bottle mouth has external threads on its outer periphery, the cover is composed of a cover body and a filtering piece, the cover body has a first air hole and internal threads which can be matched with the external threads of the bottle mouth. The filtering piece has a filtering piece body and a filtering sheet, the filtering piece body has a second air hole, a rotating sheet and a groove, the rotating sheet is used for the user to hold and detach the filtering piece from the cover body by rotating, the groove is used for accommodating the filtering sheet, and the filtering sheet is a round sheet with a microporous structure.
[0006] Preferably, the oxygen production cup does not have a filtering cavity for filtering oxygen through water.
[0007] Preferably, the filter sheet is a high-molecular microporous filter core sintered from PE powder.
[0008] Preferably, the microporous structure allows oxygen and water molecules to pass through but does not allow impurities to pass through.
[0009] Preferably, the impurities are carbon dioxide, carbon monoxide, and hydrocarbons.

In addition, the filter sheet has better filtering performance than water, so that the filtered oxygen is cleaner. In addition, the oxygen production cup according to the present application reduces manufacturing costs without a filter cavity. BRIEF DESCRIPTION OF DRAWINGS
