Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen concentrators, and in particular relates to a fan device of an oxygen concentrator and an oxygen concentrator with the fan device. Background Art

[0002] An oxygen concentrator is a device that can extract oxygen from the air. It is mainly used in the medical field to provide high-purity oxygen for patients who need additional oxygen. Molecular sieve oxygen concentrators are currently more commonly used, with two molecular sieves performing the same cycle process to achieve continuous gas supply. The workflow is: the raw air is pressurized by the compressor, and then the treated compressed air enters the molecular sieve through the intake valve, where nitrogen, carbon dioxide, etc. are adsorbed, and the outflowing gas is high-purity oxygen.

[0003] When the compressor is used to compress a large amount of filtered air, the potential energy of the molecules in the compressed air is converted into kinetic energy, and the molecules frequently collide with each other to generate heat. If the generated heat cannot be discharged in time, it will easily affect the service life of the oxygen production equipment. At present, fans are set to dissipate heat for the compressor to ensure the working environment of the compressor.

[0004] In patent CN202222910067.1, a high-efficiency heat dissipation oxygen generator is disclosed, including a shell and a compressor, a molecular sieve and a compressor heat dissipation device installed in the shell.

The first wind guiding plate 264 is inclined in the air outlet direction towards the center of the air outlet 252. By providing the wind guiding structure 26, the airflow blown out from the air outlet 252 is diverted and directly diverted to the components that need to be cooled, improving the cooling effect. By providing the first enclosure 261 and the first wind guiding plate 264, the airflow near the first wind guiding plate 264 blown out from the air outlet 252 can only flow downward along the first wind guiding plate 264, reducing the diffusion outward in the circumferential direction; and due to the inclined setting of the first wind guiding plate 264, it is beneficial to achieve the concentration of the downward flow of the airflow, so that a larger air volume blows onto the components that need to be cooled, taking away more heat.

By providing the diversion structure 26, the outward diffusion of the air flow in the air path between the air outlet 252 and the compressor 35 is reduced, and more air flow is guided to flow towards the compressor 35 to achieve a better heat dissipation effect. Specifically, the air flow blown out from the air outlet 252 is guided to the cylinder 352 of the compressor 35 through the air guiding structure 26.

By providing the first fixing flange 267, the fixing of the air guiding structure 26 is achieved by using the fastener 91. It can be arranged that the blower 25 is also fixed by the fastener 91, that is, the blower 25 and the air guiding structure 26 are simultaneously fixed to the cavity wall 33 by the fastener 91, which is beneficial to reducing the number of fasteners and improving the efficiency of the fixing operation.
