As a further improvement on the present invention, the muffler chamber is made of the first silencing cavity and the second silencing cavity, described
The fixation of first silencing cavity is connected to the second silencing cavity front end, and first silencing cavity is equipped with the extraneous air admission hole of connection, and described the
Two silencing cavities connect air-breathing door, and second silencing cavity is equipped with the intercommunicating pore of the first silencing cavity of connection.
As a further improvement on the present invention, the air admission hole and intercommunicating pore are concentric.
As a further improvement on the present invention, the intercommunicating pore has multiple, and multiple intercommunicating pores are divided equally in air admission hole axle center
Outside.
As a further improvement on the present invention, noise reduction gasket is equipped between the muffler chamber and air-breathing door.
As a further improvement on the present invention, it is connected by screw bolts between the muffler chamber and air-breathing door.
As a further improvement on the present invention, first silencing cavity and the second silencing cavity are circular hole.
As a further improvement on the present invention, the latus rectum of the silencers channel is along the first silencing cavity, the second silencing cavity, air-breathing
Door successively decreases successively.
As a further improvement on the present invention, the tail end of the air-breathing door, which is connected to, takes over, and the silencers channel includes taking over
Inner cavity.
The beneficial effects of the invention are as follows：The silencers channel of the present invention is made of the inner cavity of muffler chamber and air-breathing door, profit
The individual cavity for having used the inner cavity of the air-breathing door of compressor to be used for noise reduction as one is saved to simplify the structure of noise reduction
The occupied space of noise-reducing structure, reduces material cost and process costs.
Description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of existing compressor air suction structure；
Fig. 2 is the structural schematic diagram of first embodiment；
Fig. 3 is the structural schematic diagram of second embodiment.
Specific implementation mode
Compressor air suction noise-reducing structure as shown in Figure 2 includes the air-breathing door 2 of muffler chamber, take over 1 and compressor,
Muffler chamber is connected to the front end of air-breathing door 2, and take over 1 is connected to the tail end of air-breathing door 2, muffler chamber, air-breathing door 2 and take over 1 it is interior
Chamber constitutes silencers channel.
When compressor air suction, gas is introduced into muffler chamber and carries out preliminary filtering to sound wave, later enter air-breathing door 2 into
The follow-up acoustic wave filter of row, last gas enter compressor main body after 1 progress of take over acoustic wave filter again and use.Air-breathing door
2 are attached at the gas suction inlet of compressor, and take over 1 is located in compressor main body at this time；It is of course also possible to be that take over 1 connects
At the gas suction inlet of compressor, and it is connected on take over 1 outside air-breathing door 2.No matter what kind of situation it is, only as one, compressor
The air-breathing door 2 of vertical component becomes an individual cavity for noise reduction in the present embodiment, is used cooperatively with muffler chamber,
To simplify the structure of noise reduction, compared with the muffler in traditional technology as shown in Figure 1, the occupancy for saving noise-reducing structure is empty
Between, during the work time, noise-reducing structure is less likely to occur " touching shell " compressor.In addition, by the simplification of noise-reducing structure, it is also advantageous
In reduction material cost and process costs.
Preferably, muffler chamber is made of the first silencing cavity 3 and the second silencing cavity 4, and the fixation of the first silencing cavity 3 is connected to second
4 front end of silencing cavity, the first silencing cavity 3 are equipped with the extraneous air admission hole 6 of connection, and the second silencing cavity 4 is equipped with the first noise reduction of connection
The intercommunicating pore 7 of chamber 3, the second silencing cavity 4 connect air-breathing door 2, thus in embodiment compressor when sucking gas in three cavitys
In carried out noise reduction.Since the size of the air-breathing door 2 mating with compressor is fixed, and there are two muffler chambers, so
The occupied space of entire noise-reducing structure can be greatly reduced.
Air admission hole 6, intercommunicating pore 7, air-breathing door 2 in the present embodiment and 1 concentric setting of take over.
Preferably, it is equipped with noise reduction gasket 5 between the second silencing cavity 4 and air-breathing door 2, ensures the steady of the two installation, and
Prevent gas leakage.
It is connected by screw bolts between first silencing cavity 3 and air-breathing door 2.The edge of first silencing cavity 3 is Flange-shaped Parts, air-breathing door
2 edge is also Flange-shaped Parts, and two flanges are bolted by above-mentioned these, and noise reduction gasket 5 is clipped between two flanges.
In the present embodiment, the first silencing cavity 3 and the second silencing cavity 4 are circular hole, and the inner cavity of air-breathing door 2 is also circular hole
Shape.
Preferably, the latus rectum of silencers channel successively decreases successively along the first silencing cavity 3, the second silencing cavity 4, air-breathing door 2.First disappears
The shell of sound chamber 3 is coated at the tail end of 4 shell of the second silencing cavity, and the aperture of the second silencing cavity 4 is more than the hole of 2 inner cavity of air-breathing door
Diameter, in this way, the filtering of sound wave has gradient.
In second embodiment as shown in Figure 3, only there is air-breathing door 2, the first silencing cavity 3, the second silencing cavity 4, without
Take over 1, at this time air-breathing door 2 be directly connected on the compressor.It is also resided in the difference of first embodiment in the embodiment：Intercommunicating pore
7 have 4, and 4 intercommunicating pores 7 are divided equally in the outside in 6 axle center of air admission hole, and gas is distributed to surrounding after entering from centre, so as to
Preferable noise reduction；The outer wall of first silencing cavity 3 all surrounds the second silencing cavity 4.Meanwhile first silencing cavity 3 be bolted
Rear baffle 8, the rear baffle are fixedly connected with air-breathing door 2, and noise reduction gasket 5 is between the first silencing cavity 3 and rear baffle 8.
The above is the preferred embodiment of the present invention, does not constitute limiting the scope of the invention.
