Description

TECHNICAL FIELD

[0001] The utility model relates to an oxygen inhaling system, in particular to an oxygen inhaling system suitable for closed pressure building. BACKGROUND

[0002] The pressure building is a special building suitable for high altitude area, that is, the pressure building is inflated to make the indoor pressure reach the level of plain area, and a comfortable indoor environment is created. Most of the current pressure buildings only have the function of increasing pressure, and do not have the function of inhaling oxygen. However, inhaling oxygen under the condition of pressure increase can have a multiplier effect on the recovery of some diseases. If the closed pressure building and oxygen inhalation are combined, the problem of the need for recuperation of people in high altitude areas can be well solved.

[0003] At present, the indoor oxygen inhalation is generally realized by using an independent oxygen inhalation system, which has the following disadvantages: 1) the oxygen generator directly delivers oxygen to the indoor, which increases the overall oxygen concentration in the indoor, creates an oxygen-rich environment in the indoor, and increases the risk of fire; 2) the oxygen generator is installed outdoors, and for high altitude areas, the atmospheric pressure is lower than that of the plain area, which will cause the oxygen generation efficiency of the oxygen generator to decrease, and the oxygen inhalation to be insufficient; 3) there is no effective ventilation in the indoor, the oxygen concentration in the indoor is not uniform, which leads to local oxygen enrichment and inaccurate oxygen concentration monitoring, and increases the safety risk. UTILITY MODEL CONTENT

[0004] The utility model aims at providing an oxygen inhalation system suitable for closed pressure building, which greatly reduces the risk of fire, ensures the oxygen generation efficiency, makes the oxygen concentration in the indoor more uniform, and is convenient for maintaining the oxygen concentration in the indoor.

[0005] The utility model adopts the technical scheme of:

[0006] An oxygen inhalation system suitable for closed pressure building, comprising a pressure increasing device arranged outside the pressure building, and a air supply port, an air exhaust port, an oxygen increasing device and a circulating air device arranged inside the pressure building; the pressure increasing device is connected to the air supply port through an air supply pipeline, and the air exhaust port is communicated with the outdoor through an air exhaust pipeline; the oxygen increasing device comprises an oxygen inhalation port for people to inhale oxygen in the indoor, an oxygen generator for processing indoor air and generating oxygen in the indoor, and an oxygen concentration detection element for detecting the oxygen concentration in the indoor, and the oxygen generator is connected to the oxygen inhalation port through an oxygen supply pipeline; the circulating air device is used for providing circulating air to the indoor to make the oxygen in the indoor uniformly distributed.

[0016] The beneficial effects of the present application are:

[0017] The oxygen generating device is located inside the pressurized building, directly prepares oxygen in the room (the oxygen generating device separates oxygen and nitrogen in indoor air, fixes the nitrogen, and thus prepares oxygen), and thus the indoor oxygen concentration does not increase as a whole, greatly reducing the fire risk; in addition, the indoor air pressure where the oxygen generating device is located is higher than the outdoor air pressure, which can ensure the oxygen generating efficiency. When the indoor user needs to inhale oxygen, in addition to the operation of the oxygen generating device, the circulating air device can also be started at the same time to make the indoor air flow, which can not only make the indoor oxygen concentration distribution more uniform, avoid local space oxygen enrichment to cause the oxygen concentration to be too high to cause static electricity and fire, but also help to ensure the accuracy of the detection data of the oxygen concentration detection element.
