Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production equipment, in particular to an oxygen generator. Background Art

[0002] An oxygen concentrator is a device that uses physical methods to extract oxygen from the air. It is widely used in medical, industrial and any other fields that require high-purity oxygen. Its working principle is based on advanced air separation technology, the most commonly used of which are cryogenic distillation and pressure swing adsorption. In cryogenic distillation, the air is first compressed and cooled to a near-liquid state during cryogenic distillation, and then passes through a device called a fractionating tower. In this process, the components in the air (mainly oxygen and nitrogen) evaporate at different temperatures due to their different boiling points. By precisely controlling the temperature, oxygen and nitrogen can be separated at different stages to obtain high-purity oxygen. Pressure swing adsorption (PSA) technology relies on the properties of molecular sieves, which are porous materials with highly selective adsorption capacity. It can effectively adsorb nitrogen and almost no oxygen. In an oxygen concentrator, when the compressed air passes through the molecular sieve bed, oxygen molecules can freely pass through the micropores of the molecular sieve due to their relatively small size, while nitrogen molecules are temporarily adsorbed. Through periodic pressure changes, the adsorbed nitrogen is desorbed and released, and oxygen is enriched. To ensure a continuous and stable supply of oxygen, this process is usually alternated between two or more vessels filled with molecular sieves.

[0003] Since pressure swing adsorption can be implemented in a relatively compact space, oxygen production equipment using this technology can be miniaturized and is popular in the market. However, despite the portability and efficiency of such equipment, its structure is relatively complex and its manufacturing cost is high, which limits its large-scale popularization and application.

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 4 As shown, an oxygen concentrator of the utility model comprises: a shell 1, which has a length direction L, a height direction H and a width direction W, and an air inlet 2 and an oxygen output port 3 are arranged at one end of the shell 1 along the height direction H, and the air inlet 2 and the oxygen output port 3 are arranged on the shell 1 at intervals; a compressor 4, which is arranged in the shell 1, and the compressor 4 is provided with an intake end and an exhaust end, and the exhaust end is connected to the oxygen output port 3 through a first hose 5; an oxygen separation membrane 6, which is located at the lower end of the air inlet 2 and is connected to the intake end through a second hose 7, and the oxygen separation membrane 6 is used to separate oxygen from the gas entering the shell 1 from the air inlet 2; a battery 12, which is arranged in the shell 1 and is electrically connected to the compressor 4, and is used to power the compressor 4.

[0023] The shell 1, as the framework of the entire device, not only provides physical support, but also optimizes the resistance during air circulation through the carefully designed air inlet 2 and oxygen output port 3, thereby improving the oxygen separation efficiency. The oxygen separation membrane 6 is designed based on membrane separation technology, which utilizes the different permeation rates of different gas molecules when passing through the membrane material. Specifically, oxygen molecules have a higher permeability than nitrogen molecules. Therefore, under a certain pressure, when air passes through this membrane, oxygen will be preferentially permeated, thereby achieving oxygen enrichment.

[0024] During operation, the battery 12 powers the compressor 4, which inhales air through the second hose 7. After the air passes through the oxygen separation membrane 6, the nitrogen therein is blocked and isolated, while the oxygen enters the compressor 4 through the separation membrane, and after being compressed, it is transported to the oxygen output port 3 along the first hose 5 to meet the user's oxygen inhalation needs. This solution adopts the method of integrating the oxygen separation membrane 6 in the housing 1 to effectively separate the oxygen in the air. Subsequently, the extracted oxygen is compressed by the compressor 4 to increase the oxygen concentration, and is supplied through the dedicated oxygen output port 3, which simplifies the structure of the entire oxygen generator, not only reduces the production cost, but also promotes the widespread popularization of oxygen generators.

[0025] The oxygen separation membrane 6 is extended in the height direction H and arranged in the shell 1, and the height of the oxygen separation membrane 6 is greater than two-thirds of the height of the shell 1. This layout maximizes the area in contact with the air, thereby improving the oxygen separation efficiency, ensuring a higher concentration of oxygen output in a limited space, and enhancing the performance of the oxygen generator.

[0026] One end of the second hose away from the air intake end is connected to a three-way pipe 8 , and the other two ports of the three-way pipe 8 are connected to the oxygen separation membrane 6 .

[0027] The arrangement of the three-way pipe 8 optimizes the gas flow path, facilitates the adjustment and control of the gas flow direction, and at the same time enhances the stability of the system and the flexibility of operation, and reduces potential gas flow blockage problems.

[0028] The housing 1 is connected with a cover plate 17 , on which a position-avoiding hole 9 is integrally formed. A hollow boss 10 is arranged in the middle of the position-avoiding hole 9 , and the hollow boss 10 is used to form the oxygen output port 3 .

[0029] The design of the avoidance hole 9 and the hollow boss 10 integrally formed on the cover plate 17 is not only beautiful but also practical, which simplifies the structure of the oxygen output port 3, improves the overall sealing and durability, and is also easy to maintain and clean, reducing the complexity of assembly and the potential risk of leakage.

[0030] A base 11 is provided at the other end of the housing 1 along the height direction H, and the battery 12 and the compressor 4 are both fixed on the base 11 .

[0031] The setting of the base 11 provides a stable installation platform for the battery 12 and the compressor 4, which helps to reduce the vibration transmission during operation, improves the stability and reliability of the whole machine, and facilitates the assembly and maintenance of the equipment.

[0032] A support frame 13 is connected to the base 11, and the compressor 4 is threadedly connected to the support frame 13. A plurality of cross-arranged ribs 14 are arranged at one end of the base 11 facing the shell 1, and a placement space is formed between the plurality of ribs 14. The placement space is used to place a shock-absorbing pad pressed between the support frame 13 and the base 11.

[0033] The design of the ribs 14 on the support frame 13 and the base 11 and the use of shock-absorbing pads effectively absorb and disperse the vibration generated when the compressor 4 is running, reduce the noise level, protect internal components from vibration damage, extend the service life of the equipment, and improve the user experience.

[0034] A plurality of studs 15 are formed on the inner wall of the shell 1 and extend toward the inner side of the shell 1. Bolt holes 16 corresponding to the studs 15 are provided on the cover plate 17 and the base 11. Bolts pass through the bolt holes 16 and are connected to the studs 15 to fix the cover plate 17 and the base 11 to the shell 1.

[0035] The studs 15 on the inner and outer walls of the shell 1 are used in conjunction with the cover plate 17 and the bolt holes 16 on the base 11. This reinforced connection method greatly enhances the sealing and structural strength of the shell 1, ensures the stability and safety of the equipment during long-term operation, and also simplifies the assembly process and improves production efficiency.
