Description

Technical Field

[0001] The utility model relates to a small oxygen concentrator, in particular to a compressor water cooling device of the small oxygen concentrator. Background Art

[0002] To facilitate oxygen inhalation at any time and improve health, more and more families are purchasing small oxygen concentrators for home oxygen inhalation, and the demand for small oxygen concentrators is increasing. Since small oxygen concentrators are generally used in small spaces such as homes, users have increasingly high requirements for heat dissipation and quiet performance of small oxygen concentrators.

[0003] Traditional small oxygen concentrators use air cooling and fan heating, but the heat dissipation effect is not ideal. The reason is that the air compressor of a small oxygen concentrator generally uses a piston compressor to provide high-pressure air for the oxygen production components (such as molecular sieves). The operation of the compressor generates a lot of heat, so the compressor must be cooled. The traditional heat dissipation method is to install a cooling fan next to the compressor. In the case of a small overall product volume, the installation and power of the cooling fan are limited. It is difficult to blow cold air forcefully to the core heat-generating component of the compressor, namely the cylinder body, so the heat dissipation effect is reduced, resulting in a less than ideal heat dissipation effect.

[0004] In addition, the vibration noise generated by the compressor during operation is large and difficult to eliminate. The traditional noise reduction method is to install a soundproof cover to cover the compressor and the cooling fan as a whole. Because the cooling fan requires vents to operate, the noise of the compressor will always be transmitted to the outside of the machine through the vents. Although the noise can be reduced to a certain extent by reducing the vents, adding sound insulation materials, and improving the sealing performance, it is still impossible to significantly reduce the noise fundamentally. Therefore, the noise of traditional small oxygen concentrators is relatively large. Utility Model Content

[0026] like Figures 1-8 As shown, the present invention also discloses the following multiple more optimized specific structures:

[0027] In order to achieve better water-cooling heat dissipation effect and facilitate processing and assembly, the cylinder body 24 is located on the upper part of the compressor 14, and a water-cooling groove 36 is provided on the upper part of the cylinder body 24.

After the vacuuming is completed, the shell is assembled; when making oxygen, the oxygen generator power is turned on, and the compressor 14, the cooling fan 2, and the water pump 6 all start to run. The compressor 14 compresses the normal-pressure air in the air compression channel 37 of the cylinder body 24 to make it into high-pressure air. The high-pressure air is sent to the oxygen making component 18 for nitrogen and oxygen separation to realize the oxygen making function. In this process, the cylinder body 24 generates a lot of heat; at the same time, the water pump 6 pumps the cold water in the cold water tank 1 The cooling fan 2 blows the hot water in the heat dissipation pipe 33 so that the hot water in the heat dissipation pipe 33 gradually turns into cold water, and then the hot water is sent into the cold water tank 1 to form a water-cooling cycle, and the cooling fan 2 blows the hot air out to the outside air; the noise generated by the operation of the compressor 14 is effectively isolated by the vacuum soundproof cover 15, achieving efficient and silent performance; in this way, the requirements of efficient and silent performance and good heat dissipation performance are taken into account at the same time, and the system is suitable for home use, especially for portable use.
