Description

Technical Field

[0001] The utility model relates to the field of oxygen production equipment, in particular to a portable unpowered oxygen production device. Background Art

[0002] Oxygen is the most important substance for the human body to maintain life. If there is a lack of oxygen for a few minutes, it may cause permanent damage to the brain. Therefore, when medical staff give first aid to the injured, they generally provide the injured with high-concentration oxygen to increase the oxygen content in the injured's blood and reduce the hypoxia in the injured's brain. For the elderly, pregnant women, people with underlying diseases and other weak people, portable oxygen breathing equipment can reduce the damage caused by hypoxia in emergency situations. In addition, portable oxygen generators can alleviate altitude sickness in plateau areas.

[0003] However, most of the oxygen supply equipment, whether real-time oxygen production or reserve oxygen, is generally bulky and heavy. Real-time oxygen production equipment includes physical oxygen production and chemical oxygen production. Physical preparation equipment requires electricity supply, while chemical oxygen production equipment has safety risks due to the violent chemical reaction. In addition, both require pressure-resistant oxygen storage bins, so they are not convenient to carry or use in emergencies at any time. Therefore, there is a need for a portable oxygen production device that can produce oxygen anytime and anywhere without being restricted by conditions and provide it to people who need oxygen for direct inhalation.

Figure 1 This is a schematic diagram of the structure of a portable non-powered oxygen generator provided in Example 1 of the utility model. Figure 1 As shown, the portable unpowered oxygen generator comprises: an oxygen mask 1, a sealing cover 3, an airway 4, an isolation layer 5, and an oxygen production chamber 6. Among them, the sealing cover 3 is detachably connected to the oxygen production chamber 6 and is used to seal the oxygen production chamber 6. Specifically, in this embodiment, the sealing cover 3 is opened and closed with the oxygen production chamber 6 by screwing. The oxygen production chamber 6 is used to accommodate an oxygen-releasing material 10 that generates oxygen when it comes into contact with water. For specific materials, reference can be made to the slow-release oxygen-releasing material provided in patent ZL 202011280113.3 "A green and environmentally friendly slow-release oxygen enhancer and its preparation method". In this embodiment, such slow-release oxygen-releasing materials in the form of particles or pressed sheets are used. The isolation layer 5 is arranged at the top of the oxygen production chamber 6 to isolate the air and prevent the oxygen-releasing material 10 from getting wet. The isolation layer 5 can be, for example, a plastic film, which is sealed by pasting. At the top opening of the oxygen production chamber 6. The airway 4 passes through the isolation layer 5 and the sealing cover 3 in sequence from the oxygen production chamber 6 to the oxygen mask 1.

[0027] In a preferred embodiment, the portable unpowered oxygen generator further comprises an oxygen mask base 2. The oxygen mask base 2 is disposed at the bottom of the oxygen mask 1 and is used to connect the oxygen mask 1 to the sealing cover 3 in a fixed or detachable manner. At this time, the airway 4 passes through the isolation layer 5, the sealing cover 3 and the oxygen mask base 2 from the oxygen production chamber 6 and is connected to the oxygen mask 1. Figure 1 Optionally, the oxygen mask 1 is movably connected to the sealing cover 3 via the oxygen mask base 2, that is, the elevation angle of the oxygen mask 1 relative to the sealing cover 3 is adjustable. Preferably, the opening of the oxygen mask 1 that fits the face is perpendicular to the upper surface of the sealing cover 3, as shown in FIG. Figure 1 As shown. At this time, the airway 4 is a bent structure, and the airway 4 passes through the isolation layer 5, the side wall of the sealing cover 3 and the oxygen mask base 2 from the oxygen production chamber 6 to connect to the oxygen mask 1. When the face-fitting surface of the oxygen mask 1 and the upper surface of the sealing cover 3 are perpendicular to each other, the user can keep the oxygen production chamber 6 vertically placed when breathing oxygen, and the user can also breathe oxygen in a more comfortable posture. Preferably, the edge curve of the opening where the oxygen mask 1 fits on the face is a structure that can fit the contour of the human face.

[0028] In a preferred embodiment, the portable oxygen generator further comprises a filter membrane 8, which is disposed transversely inside the oxygen production chamber 6 to separate the oxygen production chamber 6 into a sealed oxygen preparation chamber 9 at the bottom and an oxygen collection chamber 7 at the top. The filter membrane 8 is used to filter oxygen and isolate fine particles to ensure the output of pure oxygen. The filter membrane 8 is water-permeable and air-permeable. When the sealing cap 3 is unscrewed before use to add pure water to the oxygen production chamber 6, there is no need to remove the filter membrane 8. The pure water can penetrate into the oxygen preparation chamber 9 through the filter membrane 8 and react chemically with the oxygen-releasing material 10 therein to produce oxygen.

[0029] In this embodiment, the oxygen production chamber 6 can be a barrel-shaped or bottle-shaped container made of glass, plastic or the like, preferably with a volume of 100ml-1000ml.

[0030] The following is an introduction to the use of the portable oxygen generator of the utility model, and the specific steps are as follows:

[0031] Step 1: Open the sealing cover 3, uncover the isolation layer 5, and add pure water to the oxygen production chamber 6 containing the oxygen-releasing material to at least immerse the oxygen-releasing material;

[0032] Step 2: Seal the isolation layer 5 and close the sealing cover 3;

[0033] Step 3: The oxygen-releasing material continuously generates oxygen when in contact with water. After the oxygen is generated, the air pressure in the oxygen-generating chamber 6 increases, so that the oxygen passes through the filter membrane 8 and flows to the oxygen mask 1 through the air guide tube 4 on the sealing cover 3 .

The bulkhead of the oxygen preparation cabin 9 is provided with a pressing component 12, and a piercing tip is provided at the end of the pressing component 12. When the pressing component 12 is pressed from the outside of the oxygen production chamber 6, the piercing tip is used to pierce the water storage bag 11, and the water in the water storage bag 11 flows out and reacts with the oxygen-releasing material 10 in the oxygen production chamber 6 to release oxygen.
