The present invention relates to an oxygen generation apparatus.
The demand of a human body for oxygen is self-evident. The sufficient oxygen supply helps relieve stress and sober up the brains. In addition to the demands of health care, in aspects of medical treatment and first aid, for example, when first aid is performed on an asthma patient or when a fire accident occurs in an entertainment site, a carry-on oxygen generation apparatus is more needed to prevent loss of lives and property.
It is well-known that the oxygen generation apparatus includes the following types: (1) a pressurized oxygen cylinder, where oxygen is fed into a cylinder in a high pressure manner by using a compressor for storage, and when oxygen is needed, the oxygen cylinder is used in cooperation with a respirator to supply oxygen for a user to use; (2) an air-separation-type oxygen generation apparatus, where compressed air is filtered by using a molecular sieve to separate the oxygen; and (3) a chemical-reaction-type oxygen generation apparatus, where a chemical action is performed on an oxygen generating agent by using a catalyst in the apparatus, and accelerated decomposition is performed on oxygen molecules in the oxygen generating agent to supply oxygen.
However, the foregoing oxygen generation apparatuses all have disadvantages. An oxygen cylinder is heavy, and it is difficult to store the oxygen cylinder, when oxygen is supplemented, the oxygen must be supplemented at a specific site; and a compressor of the oxygen cylinder needs to use a power supply to pressurize the oxygen, so the entire apparatus is complex. An air-separation-type apparatus is costly and needs to use a power supply to filter air, a volume of the apparatus is huge, the apparatus can only be deployed at a specific site, and the apparatus needs to be maintained as scheduled. If a chemical-reaction-type apparatus uses sodium borate as an oxygen generating agent, a heat source is needed to perform decomposition on sodium borate.
In view of the above, the greatest disadvantages of known oxygen generation apparatuses is that it is difficult to carry them for use; and in an emergency where oxygen medical treatment is needed, it is impossible to use the oxygen generation apparatus to supply oxygen immediately. Further, for a chemical-reaction-type apparatus, after an oxygen generating agent stops generating oxygen, an oxygen generating agent needs to be supplemented by oneself. However, it is difficult to store and carry an oxygen generating agent.
In view of this, the present invention proposes an oxygen generation apparatus.

An inner side surface of the container lid 20 is provided with an inner screw thread 26, and an outer edge of an opening end of the outer container 10 is provided with an outer screw thread 11 matching the inner screw thread 26. Hence, the inner screw thread 26 is connected in a screwed manner to the outer screw thread 11 to enable the container lid 20 to be locked in a spinning manner to the opening end of the outer container 10, so as to seal an opening of the outer container 10. In addition, a bottom plate 25 of the container lid 20 is provided with a hole 22 for oxygen to diffuse.
