Detailed Description

Referring to fig. 1 to 5, in the embodiment of the present invention, a noise reduction device for a small household oxygenerator includes a chassis 1, a sound insulation plate 3 and a sound absorption plate 2, wherein the sound insulation plate 3 is bonded on the top of the chassis 1 through a structural adhesive, the sound absorption plate 2 is bonded right ahead of the sound insulation plate 3, four fixing plates 101 are tightly bonded on the bottom of the chassis 1, four rotating balls 102 are movably embedded in the bottom of the chassis 1, two screws 103 are embedded in the bottoms of the fixing plates 101, and a plurality of sound absorption holes 201 are arranged in an opening of the sound absorption plate 2;

the acoustic baffle 3 comprises a butt joint pipe 301, a gasket 302, a baffle 303, an elastic steel wire 304 and a rubber ring 305, the butt joint pipe 301 is seamlessly embedded in the right side of the acoustic baffle 3, the gasket 302 is embedded and bonded on the inner wall of the butt joint pipe 301, the baffle 303 is hinged to the right side of the gasket 302 through a hinge, the elastic steel wire 304 is arranged inside the butt joint pipe 301, two ends of the elastic steel wire 304 are respectively bonded on the left side of the gasket 302 and the left side of the baffle 303, and the rubber ring 305 is embedded and bonded on the surface of the butt joint pipe 301.

Preferably, the rotating ball 102 respectively penetrates through the four fixing plates 101, and the groove inside the fixing plate 101 is matched with the rotating ball 102, the rotating ball 102 can rotate on the chassis 1, so as to reduce the friction between the chassis 1 and the ground, so that people can move more easily, and the fixing plate 101 has the advantage of convenient movement, the fixing plate 101 is fixedly connected below the chassis 1 through the screw 103, the fixing plate 101 is positioned below the center of the circle of the rotating ball 102, the fixing plate 101 can prevent the rotating ball 102 from falling off from the chassis 1, the sound insulation plate 3 is hollow, the thickness of the sound insulation plate 3 is half of that of the sound absorption plate 2, the air inside the sound insulation plate 3 can effectively isolate noise after being evacuated, and the sound insulation plate 3 has very strong sound insulation capacity by utilizing the principle that sound cannot be transmitted in vacuum, the sound absorption holes 201 are uniformly distributed in the sound insulation plate 3, and the sound absorption holes 201 can absorb the noise emitted by the, the sound absorbing hole 201 is "S" shaped, which can improve the noise absorbing ability of the sound absorbing hole 201, so that the sound is fully absorbed by the sound absorbing hole 201.
