Problems solved by technology

[0005] Such a structure allows the direct sound of the compressor to be easily transmitted to the outside world. The length of the air duct is too short, there is no noise reduction effect, and there is no space for noise reduction, resulting in high overall operating noise of the oxygen generator.

Embodiment 1

[0036] see figure 1 and figure 2 As shown in the figure, it is the structure diagram of the first embodiment of the U-shaped heat dissipation and noise reduction channel of the oxygen generator in the present invention combined with the compressor and the cross-sectional view of the first embodiment. A U-shaped heat dissipation and noise reduction channel of an oxygen generator is arranged under a compressor 4 for noise reduction and heat dissipation, and includes a bottom plate 1 , a chassis base 2 and a base 3 .

[0037] The bottom plate 1 is installed on the chassis base 2 to support the compressor 4; the chassis base 2 is arranged above the base 3 to control the direction of the airflow; the base 3 is provided with a noise reduction device for to dissipate heat.

[0038] Please combine image 3 As shown, it is a top view of the base in Embodiment 1 of the U-shaped heat dissipation and noise reduction channel of the oxygen generator of the present invention. The base p...

Embodiment 2

[0043] see Figure 7 It is a structural diagram of the second embodiment of the U-shaped heat dissipation and noise reduction channel of the oxygen generator in the present invention combined with the compressor. This embodiment has the basic structure of the above-described embodiments. Wherein, a sealing ring 11 is arranged between the chassis base 2 and the base 3 , and the sealing ring 11 is a waist-shaped structure, which is matched with the structure of the chassis base 2 and the base 3 . Threaded holes are arranged at intervals on the sealing ring 11 for better fixing with the base 3 and the chassis base 2 . The setting of the sealing ring 11 can effectively seal, prevent noise and air flow from overflowing, and better reduce noise.

Embodiment 3

[0045] see Figure 8 It is a structural diagram of the third embodiment of the U-shaped heat dissipation and noise reduction channel of the oxygen generator in the present invention combined with the compressor. This embodiment has the basic structure of the above-described embodiments. Wherein, an air outlet louver 12 is provided at the air outlet 301 of the base 3 to reduce noise.

[0046] The design of the U-shaped air channel in the present invention lengthens the noise reduction and heat dissipation channel, and at the same time, a melamine sponge is arranged in the lower channel to absorb noise. The design of the sealing ring 11 can effectively prevent noise from spilling out, Setting the air outlet louvers 12 at the air outlet 301 can also effectively reduce noise. Moreover, the base plate 1 in the present invention is made of sheet metal, which is light in weight, high in strength, low in cost, and conducive to mass production. The chassis base 2 is made of plastic,...

Abstract

The invention provides a U-shaped trend heat-dissipating noise-reducing channel for an oxygen generator. The U-shaped trend heat-dissipating noise-reducing channel comprises a bottom plate, a machine box base and a base. Ventilation holes are formed in the two sides of the bottom plate which is arranged below a compressor. The machine box base is arranged below the bottom plate and matched with the bottom plate in structure. A first end of the machine box base is hollow. A slope-shaped plate is arranged at a second end of the machine box base. The gradient of the slope-shaped plate is decreased progressively to the first end. A ventilation opening is formed between the slope-shaped plate and the inner wall of the first end. The middle of the base is hollow for arranging the machine box base. A bottom supporting plate is arranged at the end, matched with the first end, of the base. The bottom supporting plate extends towards the direction of the second end, and an air outlet is formed in the end, matched with the second end, of the bottom supporting plate. According to the U-shaped trend heat-dissipating noise-reducing channel for the oxygen generator, the slope-shaped plate in the machine box base, the base and the bottom plate are combined to form the U-shaped trend heat-dissipating noise-reducing channel for the oxygen generator, through the design, an air channel is lengthened, and therefore more space is reserved for silence design.

Description

technical field [0001] The invention relates to a noise reduction device for an oxygen generator, in particular to a U-shaped cooling and noise reduction channel for an oxygen generator. Background technique [0002] At present, there is a phenomenon of high operating noise in the overall oxygen generator market, which will cause certain noise pollution to consumers during actual use. [0003] In the prior art, the noise reduction method in the oxygen generator market is too simple. The fan is installed directly above the compressor, and the cold air blows through the compressor through the fan, and then it is discharged out of the machine through the air duct. At present, most of the outlet air ducts Noise reduction is only done through the louvers. Such a structure allows the direct sound of the compressor to be easily transmitted to the outside world. The length of the air duct is too short, there is no noise reduction effect, and there is no space for noise reduction, re...
