The quiet noise reduction oxygenerator of claim 1, characterized in that: second grade base (3) inside intermediate position is fluted for place temperature sensor (31), be used for detecting the exhaust temperature of one-level base heat extraction mouth (401), second grade base (3) inside is pasted and is had egg type amortization cotton (32) for absorb the noise that spreads from one-level base heat extraction mouth (401), second grade base (3) are opened all around there are strip groove (301), can change the direction from one-level base (41) exhaust air current, and buffering and dispersion air current energy reduce the noise that exhaust air current produced when carrying out quick heat extraction.
10. The quiet noise reduction oxygenerator of claim 1, which is characterized in that: install compressor housing (47) inside paste in one-level base (41) top and have the amortization cotton, can absorb the noise that compressor (50) produced, preceding shell (2) and backshell (5) of base top form the oxygenerator and seal the inner chamber space, and the inner wall is all pasted and is had the amortization cotton, absorbs oxygenerator internal noise, furthest prevents the diffusion of oxygenerator internal noise.
11. The quiet noise reduction oxygenerator of claim 1, characterized in that: preceding shell (2) are gone up and are still installed operating panel (1), operating panel (1) inboard is installed and is assembled printed circuit board module for logic control when the oxygenerator moves, implant PWM intelligence temperature control program in the assembly printed circuit board module, detect the temperature of oxygenerator exhaust gas through temperature sensor (31) of second grade base (3) intermediate position, turn into analog signal with temperature signal and transmit for MCU.
