In further technical solution, the edge of the muffler cover board has bending part, and the bending part disappears towards described
Sound device extends.
In further technical solution, the bending part is along the muffler cover board towards the length in the muffler direction
Degree.Greater than the set distance.
In further technical solution, the muffler includes muffler ontology and mounting flange, in the muffler lid
In-plane where plate, the projection of muffler ontology cover the projection of the muffler cover board.
In specific technical solution, the muffler cover board is an integral molding structure with the muffler.
In optional technical solution, the muffler cover board and the muffler are welding structure, bonded structure, screw thread company
Binding structure or interference fit mounting structure.
Gas bumps against muffler cover board after the discharge of the venthole of muffler, then between muffler cover board and muffler
Gap discharge, in this process, the movement velocity of gas reduces, second level noise reduction is realized in muffler cover board, generation
Noise is reduced.In addition, in the present embodiment, after the gas being discharged from muffler encounters muffler cover board, from muffler cover board with disappear
Between sound device gap discharge, therefore, will not impact rotor, thus can also reduce gas shock rotor generation flow-disturbing make an uproar
Sound, it is further to reduce the noise generated using the product of the muffler structure.
The technical solution of the utility model additionally provides a kind of compressor, which includes in any of the above-described technical solution
Muffler structure.

Specific embodiment
For the erasure effect for improving muffler, the pneumatic noise of compressor is reduced, the utility model embodiment provides one
Kind muffler structure and compressor.To keep the purpose of this utility model, technical solution and advantage clearer, by the following examples
The utility model is described in further detail.
As depicted in figs. 1 and 2, the muffler structure that an embodiment of the present invention provides includes muffler 1 and and noise reduction
The muffler cover board 2 that device 1 is fixedly connected, in which: muffler 1 has venthole 11, and muffler cover board 2 and muffler 1 are close to disappear
There is set distance between the surface of sound device cover board 2, and at least cover the venthole 11 of muffler 1.
In specific embodiment, compression mechanism mainly includes cylinder, base bearing, supplementary bearing, piston, crankshaft and slide plate,
Wherein: motor includes rotor and stator, and stator is fixed on compressor housing, and rotor is fixed on crankshaft, the motor of compressor
Rotor rotates after energization, and then drives crank rotation, and crankshaft drives the piston rotation in cylinder with the refrigerant in compression cylinder, sliding
The space of cylinder interior is divided into high pressure chest and low pressure chamber together by piece and piston, and piston compression refrigerant during rotation makes height
Intracavitary pressure rise is pressed, when pressure rise to the external pressure for being slightly larger than compression mechanism, pressurized gas refrigerant can pass through countershaft
Enter muffler 1 after the gas vent discharge held, is discharged later from the venthole 11 of muffler 1.In the embodiment, disappear from above-mentioned
The gas that the venthole 11 of sound device 1 is discharged can bump against muffler cover board 2, then the seam between muffler cover board 2 and muffler 1
Gap discharge, in this process, the movement velocity of gas reduce, and second level noise reduction, the noise of generation are realized in muffler cover board 2
It reduces.In addition, in the present embodiment, after the gas being discharged from muffler 1 encounters muffler cover board 2, from muffler cover board 2 and noise reduction
Between device 1 gap discharge, therefore, will not impact rotor, thus can also reduce gas shock rotor generation flow-disturbing noise,
It is further to reduce the noise generated using the product of the muffler structure.
In specific embodiment, above-mentioned set distance refers to surface and muffler court of the muffler cover board towards muffler
To the distance between the surface of the muffler cover board, which is greater than 0 and can set according to actual needs, certain
In range, set distance is bigger, and there is air-flow more spaces to slow down, and still, set distance is set larger, can also lead
It causes muffler structure integrally larger, is easy to appear constructive interference.
With continued reference to FIG. 1, the edge of muffler cover board 2 has bending part 21, bending part 21 extends towards muffler 1.
In the embodiment, air-flow is moved with 2 inner wall of muffler cover board, meets further converting motion direction after bending part 21,
The movement velocity of air-flow can be reduced, further so as to further reduce noise.
Referring to FIG. 3, in further embodiment, bending part 21 is along muffler cover board 2 towards the length in 1 direction of muffler
Greater than set distance.
In the embodiment, gas deceleration cavity is formed between muffler cover board 2 and muffler 1, is conducive to further drop
The movement velocity of low-flow, so as to further reduce noise.
Referring to FIG. 2, muffler 1 includes muffler ontology 12 and mounting flange 13, the plane where muffler cover board 2
Direction, the projection of the projection covering muffler cover board 2 of muffler ontology 12.
In the embodiment, in the in-plane where muffler cover board 2, the profile and muffler ontology of muffler cover board 2
12 profile is almost the same, therefore, it is possible to reduce the interference with peripheral structure.
