Description

Technical Field

[0001] The utility model relates to a door frame structure of a square oxygen cabin, belonging to the technical field of oxygen cabins. Background Art

[0002] The micro-hyperbaric oxygen chamber is a sealed chamber that provides high-concentration pure oxygen for users to breathe. The treatment effect is achieved by controlling the air pressure in the chamber. Normally, the air pressure in the chamber is adjusted to a micro-high pressure state, generally around 1.3 atmospheres. This micro-high pressure helps reduce the formation of bubbles in tissues and promotes blood circulation. When receiving treatment in a micro-hyperbaric oxygen chamber, the user needs to enter the chamber and stay there for a period of time. During the treatment, the user breathes high-concentration pure oxygen in a micro-high pressure environment, which can help improve blood circulation, reduce inflammatory responses, and promote wound healing.

[0003] The micro-hyperbaric oxygen chamber has a hatch for entering and exiting the chamber body. The hatch not only serves the purpose of entering and exiting the chamber body, but also serves to seal the chamber body when the chamber is working. The hatch doors of some existing oxygen chambers act directly on the chamber body. Although the requirements for the sealing of the hatch door when the chamber is working can be met, the appearance of this oxygen chamber is not very beautiful. In particular, micro-hyperbaric oxygen chambers have gradually become health care equipment in the home. People not only require the oxygen inhalation health care effect of the oxygen chamber, but also attach great importance to the appearance of the oxygen chamber placed at home. For example, they will choose a small square oxygen chamber. If the hatch door acts directly on the chamber body, on the one hand, the sealing effect between the hatch door and the chamber body is not good. On the other hand, the chamber body acts on the hatch position without a reinforced structural design. It is easy to deform for a long time, which will affect the sealing problem of the hatch door. The hatch door is relatively easy to replace and maintain, but the chamber body is not easy to maintain, and the maintenance cost is often very high. Summary of the invention
