Description

Technical Field

[0001] This utility model belongs to the field of oxygen generators, and in particular relates to an integrated molecular sieve shell structure for an oxygen generator and the oxygen generator thereof. Background Technology

[0002] Molecular sieve oxygen concentrators are devices that utilize the adsorption properties of molecular sieves to separate and produce high-purity oxygen from the air. Currently, oxygen concentrators are not only used in the medical field but are also gradually entering the home and outdoor sectors. Therefore, as oxygen concentrators have become widely available in consumer applications, both in homes and outdoors, molecular sieves, as consumables, require more frequent replacement. However, existing molecular sieve replacement methods are often inconvenient. For example, Chinese patent CN213375841U provides a quick-release sealed molecular sieve for use in oxygen concentrators. This oxygen concentrator includes a casing and a base. The casing houses a compressor, a molecular sieve body, an oxygen outlet channel, an air inlet channel, a nitrogen exhaust channel, and a multi-way solenoid valve. The molecular sieve body is connected to the oxygen outlet channel and the air inlet channel via a plug-in connection. The air inlet channel is connected to the nitrogen exhaust channel and the compressor via the multi-way solenoid valve. While this design allows for the replacement of the molecular sieve body, the entire structure is located within the casing, making replacement of this core component inconvenient. Therefore, this application addresses this need.

[0003] It should be noted that the information disclosed in the background section of this utility model is intended only to enhance the understanding of the general background of this utility model, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0012] Preferably, the top of the semi-enclosed structure forms an opening opposite to the first base plate, and the panel covers the opening.

[0013] To achieve the above objective, this utility model also provides an integrated molecular sieve oxygen generator, comprising an oxygen generator body, a molecular sieve cylinder, and an integrated molecular sieve shell structure for the oxygen generator.

When replacing the molecular sieve cylinder, the integrated connector on top can be directly removed from the main body of the oxygen generator. Attached Figure Description

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0035] It should be noted that the oxygen generator is a device that physically separates oxygen using molecular sieves. Its principle is as follows: First, the incoming air is filtered and compressed by an air compression assembly. Then, a four-way solenoid valve distributes the gas into the molecular sieve assembly. The molecular sieve assembly includes two molecular sieve adsorption towers, which work alternately. The four-way solenoid valve directs compressed gas into one of the molecular sieve adsorption towers. Based on the different adsorption capacities of the molecular sieve for nitrogen and oxygen, nitrogen is adsorbed and oxygen is discharged. The oxygen is then detected by an oxygen concentration sensor and enters the oxygen storage tank. After a period of operation, the four-way solenoid valve alternates with the other molecular sieve adsorption tower, and the first molecular sieve adsorption tower undergoes backflushing to remove nitrogen. This process repeats continuously. This is a necessary prerequisite for understanding the scheme of this embodiment.

[0067] The beneficial effects of this embodiment:

[0068] By designing the molecular sieve as a modular structure, it is convenient for users to quickly replace it, thereby reducing the downtime and maintenance costs of the oxygen generator and extending its service life; in addition, the molecular sieve shell 1 is also a fully detachable structure, making it easier to replace the molecular sieve cylinder 23.

[0069] Through modular design, the molecular sieve cylinder 23 can be quickly disassembled and installed. Users can directly connect to the molecular sieve unit and replace the molecular sieve without disassembling the entire oxygen generator, thus realizing convenient and quick disassembly and maintenance of the molecular sieve.

[0070] The gas inlet and oxygen outlet interfaces of the molecular sieve are integrated on the top, which facilitates integration and docking with the main body of the oxygen generator 4, making it simple, convenient and efficient.

[0071] The integrated connector 212 integrates a gas guide extension tube 213, which is connected to the molecular sieve oxygen supply channel to ensure smooth oxygen delivery. When replacing the molecular sieve cylinder 23, the integrated connector 212 on the top can be directly removed from the oxygen generator body 4.

[0072] Furthermore, the present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
