Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein
Same or similar label represents same or similar element or the element with same or like function from beginning to end.Lead to below
It is exemplary to cross the embodiment being described with reference to the drawings, it is intended to for explaining the utility model, and it is not intended that to this practicality
New limitation.
As shown in Figure 1 to Figure 3, the present embodiment provides a kind of noise cancelling type compressor case, including body 1, the body 1 are set
Screw hole 2 and the piston hole 3 connected with screw hole 2 are equipped with, the bottom of the body 1 is provided with recessed groove 4, the recessed groove
Noise reduction unit 41 is provided with 4.Noise reduction unit 41 can be muffler either silencing cotton or noise reduction stone etc., pass through noise reduction unit
41 eliminate vibrations during compressor operating and noise, substantially reduce noise.It is living as preferred embodiment of the present utility model
The end of consent 3 is circumferentially provided with some screws 31 along it, and body 1 can be by being contained in some screws 31 with cylinder head
Bolt is connected；The end set of piston hole 3 has annular groove 32, and elastic washer is provided with annular groove 32（It is not shown）, it is living
Consent 3 is used to by bolt be connected with the cylinder head of compressor, and in use, elastic washer can play damping noise abatement
Effect.
The noise reduction unit 4 is some silencing cottons.Silencing cotton is set simply, can directly be bonded in recessed groove 4.
The piston hole 31 includes two groups, and axis of the axis of each piston hole 31 with the screw hole 2 hangs down
Directly, the middle part of two groups of piston holes 31 is provided with bloop 5, and the bloop 5 passes through air-flow micropore 51 with the piston hole 3
It is connected.Multiple piston holes 31 are set so that the operating efficiency of compressor is higher.Air-flow micropore 51 can prevent gas in piston hole 31
Pressure is higher than the maximum pressure that compressor can bear, and improves the security performance of compressor.
The diameter parallel of the center line of the bloop 5 and the screw hole 2, it is provided with the bloop 5 some recessed
Male structure 52；One end of the bloop 5 and ft connection, the top of the body 1 are provided with another with the bloop 5
Hold the second through hole 53 of connection, the center line of the second through hole 53 and the central axis of bloop 5.If set again in bloop 5
