Description

Technical Field

[0001] The utility model belongs to the technical field of air filtration, and in particular relates to an air filtration device for an oxygen concentrator. Background Art

[0002] An oxygen concentrator is a machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the various components in the air are used to separate the gas and liquid at a certain temperature. Then, distillation is performed to separate it into oxygen and nitrogen. The oxygen production process requires filtration through a filter device. The air filtration of the oxygen concentrator is divided into two parts: inlet filtration and outlet filtration.

[0003] Based on the above, the inventors have found that the existing oxygen concentrator air filter device has the following deficiencies:

[0004] 1. When air passes through the filtered liquid, the bubbles are large, which prevents the air from fully contacting the liquid. It is not convenient to install a foaming device to ensure that the air is fully in contact with the filtered liquid.

[0005] 2. The connection method between the device and the pipeline is plug-tightening, which may easily cause the device and the pipeline to separate due to malfunction. It is inconvenient to install locking measures on the device to lock the pipeline to prevent separation from the device. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an oxygen concentrator air filter device to solve the problem that the existing air bubbles are large when passing through the filtered liquid, resulting in the air being unable to fully contact the liquid, and it is inconvenient to install bubbling measures on the device to allow the air to fully contact the filtered liquid; the connection method between the device and the pipeline is plugging, which can easily cause the device to separate from the pipeline due to malfunction, and it is inconvenient to install locking measures on the device to lock the pipeline to prevent separation from the device.

[0007] The purpose and effect of the oxygen concentrator air filter device of this utility model are achieved by the following specific technical means:

[0010] Furthermore, a regular hexagonal ring plate is provided in the middle of the outer circumference of the filter outlet cylinder, and a conical ring groove is provided on the outer circumference of the upper end of the filter outlet cylinder.

[0011] Furthermore, a filter air outlet cylinder is installed in the top of the threaded hole at the right end of the bottle closing cover in the up and down directions, and a thread is provided on the outer circumference of the filter air outlet cylinder.

The inner circumference of the top of the liquid storage bottle 5 is provided with a threaded annular groove, which is convenient for the bottle closure cover 4 to be threadedly installed.
