Description
Technical field
The utility model is related to noise reduction technical field more particularly to a kind of mufflers and compressor.
Background technology
Noise pollution is one of the world today's three overall situation pollution.
Compressor is a kind of equipment of the high loudness noise of radiation, is a kind of main man-made noise pollution sources.Reciprocating-piston
Sucking and discharge process of the formula compressor due to every one turn of operation are spaced, and compressor is to pipeline intermittently air-breathing or exhaust
Cause gas.The pressure wave of pulsation will produce periodical change along pipe transmmision at the turning of pipeline or changes of section
The active force of change, so as to cause the vibration and noise radiation of pipeline.The periodically variable active force still results in Management of Pipeline Mechanical Equipment
The exciting force of vibration easily causes Management of Pipeline Mechanical Equipment to resonate, pipeline when the excited frequency of exciting force and the overlapping of the intrinsic frequency of pipeline
Mechanical oscillation conduit fittings and its connecting portion can be caused to occur to loosen or fatigue rupture, to generate stronger pipe Vibration
Dynamic and noise radiation.
Pipe vibration and noise radiation are presently mainly solved the problems, such as by way of thickening shell, are realizing this skill
During art scheme, the inventor finds that the existing technology has at least the following problems：Shell thickeies mode and is still not able to thoroughly
Solve the problems, such as pipe vibration and noise radiation.
Utility model content
The purpose of this utility model is to provide a kind of muffler and compressor, and the utility model subtracts vascular by installation, subtracts
The pulsation of small compressor discharge air-flow is to noise-decreasing.
To solve the above problems, the first aspect of the utility model provides a kind of muffler, including：A kind of muffler,
Including muffler ontology, muffler ontology surrounds air-breathing part and discharge portion, and air-breathing part includes to same side opening
One cavity and groove；Discharge portion includes totally enclosed second cavity, be arranged in the connectivity part of the second cavity and the first cavity and
Subtract vascular for be connected to the first cavity and the second cavity, wherein the cavity size of the second cavity is more than the cavity of the first cavity
Size；And it is inserted in the hush pipe of the outside on muffler ontology and for the air column in the second cavity to be discharged to muffler.
Further, 2 times of the cavity size of the second cavity substantially cavity size of the first cavity.
Further, air-breathing part is vertically arranged with discharge portion.
Further, muffler ontology is integrated.
Further, muffler ontology includes that the first noise reduction lid and the second noise reduction lid, the two are welded to form muffler ontology.
It is according to the present utility model that another aspect provides a kind of compressor including above-mentioned muffler, muffler sheets
The open side of the first cavity and groove on body is welded with the acoustical panel welded with compressor, is opened with the first cavity on acoustical panel
It is provided with corresponding trepanning at mouth and the corresponding position of groove, is additionally provided on acoustical panel more for what is be fixedly connected with compressor
A mounting hole.
The above-mentioned technical proposal of the utility model has following beneficial technique effect：The utility model subtracts arteries and veins by increasing
Pipe, changes the intrinsic frequency of air column so that the frequency avoids the frequency of exciting force；By the way that the second cavity is set greater than
One cavity so that entering the current density of the air column in the first cavity reduces, to reduce noise.

Specific implementation mode
To make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment
And with reference to attached drawing, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit the scope of the utility model.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid not
Necessarily obscure the concept of the utility model.
Fig. 1 is a kind of structural schematic diagram of muffler provided by the utility model.
As shown in Figure 1, 2, 3, the utility model provides a kind of muffler, including：Muffler ontology, muffler ontology enclose
At air-breathing part 1 and discharge portion 2, air-breathing part 1 includes the first cavity 11 and groove 12 to same side opening；Discharge portion
2 include totally enclosed second cavity 21, is arranged in the second cavity 21 with the connectivity part of the first cavity 11 and for being connected to the first sky
Chamber 11 and the second cavity 21 subtract vascular 3, wherein the cavity size of the second cavity 21 is more than the cavity size of the first cavity 11；
And it is inserted in the hush pipe 4 of the outside on muffler ontology and for the air column in the second cavity 21 to be discharged to muffler.
As shown in Figure 1, in order to save the space of muffler, air-breathing part 1 and discharge portion 2 can be vertically arranged.It will
After air-breathing part 1 is set perpendicularly to discharge portion, the occupied space of muffler is greatly saved.
Preferably, 2 times of the cavity size of the second cavity 21 substantially cavity size of the first cavity 11.Theoretically come
It says, it is only necessary to the second cavity 21, which need to be more than the first cavity 11, can play the purpose for reducing current density, in conjunction with cost consideration,
It is preferred that by 2 times of the cavity size of the second cavity 21 substantially cavity size of the first cavity 11.
Optionally, muffler ontology can be integrally formed, can also by the first noise reduction lid 110 and the second noise reduction lid 120, two
Person is welded to form muffler ontology.
The utility model additionally provides a kind of compressor including above-mentioned muffler, the first cavity on muffler ontology
11 and the open side of groove 12 be welded with the acoustical panel 5 welded with compressor, on acoustical panel 5 with the opening of the first cavity 11 and recessed
Slot is provided with corresponding trepanning at 12 corresponding position, is additionally provided on acoustical panel 5 multiple for what is be fixedly connected with compressor
Mounting hole 51.The low pressure extraneous for compressor sucking of groove 12, the first cavity 11 generate its inside for compressor
Hyperbar is discharged, and the air column in first cavity 11 is transported in the second cavity 21 by subtracting vascular 3, into the second cavity 21
Gas density afterwards reduces, then the outside of muffler is discharged to by hush pipe 4.
The utility model is intended to protect a kind of muffler and compressor, the utility model to subtract vascular by increasing, change
The intrinsic frequency of air column so that the frequency avoids the frequency of exciting force；By the way that the second cavity is set greater than the first cavity, make
The current density reduction for entering the air column in the first cavity is obtained, to reduce noise.
It should be understood that the above-mentioned specific implementation mode of the utility model is used only for exemplary illustration or explains this reality
With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model
