Abstract
The utility model relates to a kind of noise-reducing structures of compressor, the compressor includes compressor case, bottom plate and compression pump, the air inlet cavity being separated by air inlet cavity shell and the compression pump housing being separated by compression pump cavity shell are equipped in compressor case, the air inlet cavity shell and compression pump cavity shell it is fastened to each other connection and be each attached on bottom plate, compressor case covers on air inlet cavity shell and compression pump cavity shell, the compression pump is hung in compression pump housing, compression pump is suspended in compression pump housing in the utility model, so that the maximum noise source of compression pump, by being enclosed in the intracavitary elimination of independent compression pump-type, the vibration of compression pump simultaneously is not resonated with generations such as shells, reduce the generation of noise.
Description
Technical field
The utility model relates to a kind of noise-reducing structure more particularly to a kind of noise-reducing structures of medical compressor.
Background technique
The instruments such as ventilator and Anesthesia machine are often used in medical field, are equipped with compressor in ventilator and Anesthesia machine,
For providing compressed air, noise can be generated in the compression pump operational process in compressor, current compressor erasure effect is not
Obviously.
Utility model content
In order to solve the problems in the existing technology the utility model, provides a kind of disappearing for the compressor of good muffling effect
Sound structure.
In order to achieve the above object, the utility model proposes technical solution are as follows: a kind of noise-reducing structure of compressor, it is described
Compressor includes compressor case, bottom plate and compression pump, is equipped with the inlet chamber being separated by air inlet cavity shell in compressor case
Body and the compression pump housing being separated by compression pump cavity shell, the air inlet cavity shell and the connection fastened to each other of compression pump cavity shell
And be each attached on bottom plate, compressor case covers on air inlet cavity shell and compression pump cavity shell, and the compression pump hangs on pressure
In contracting pump housing.
Above-mentioned technical proposal is further designed to: being fixed with spring at the top of the compression pump, spring one end, which is equipped with, to be hung
Hook, compression pump are suspended on compression pump cavity shell by spring and hook.
The inlet chamber inner walls are pasted with puigging.
The compression pump cavity shell inner wall is pasted with puigging.
The compressor case inwall is pasted with puigging.
The puigging is made of three layers of different quieter material.
The utility model has the following beneficial effects:
Compression pump, which is set, in the utility model is suspended in compression pump housing, so that the maximum noise source of compression pump, passes through envelope
It closes in the intracavitary elimination of independent compression pump-type, while compression pump is not contacted with compression pump cavity shell or bottom plate fixation, can be reduced pressure
Contracting pump operation bring resonance noise.
Compression pump is set in independent compression pump housing in the utility model, and the air inlet module of compression pump is set to independence
Inlet chamber body in, be equipped in compression pump housing, air inlet cavity and compressor case and be made of three layers of different acoustic material
Puigging, carry out noise reduction isolation for different scale.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is compression pump cavity body structure schematic diagram in Fig. 1.
Fig. 3 is air inlet cavity structural schematic diagram in Fig. 1.
Fig. 4 is the compressor outer casing structure schematic diagram of the embodiment of the present invention.
In above-mentioned attached drawing: 1- compresses pump housing, 11- compression pump cavity shell, 2- air inlet cavity, 21- air inlet cavity shell, 3- pressure
Contracting pump, 4- spring, 5- compressor case, 6- bottom plate.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in detail.
Embodiment
As shown in Figure 1, the compressor in the present embodiment includes compressor case 5, bottom plate 6 and compression pump 3, consolidate on bottom plate 6
Surely there are air inlet cavity 2 and compression pump housing 1, air inlet cavity 2 is that the air inlet cavity shell 21 made of metal plate is separated, compression pump
Cavity 1 is that the compression pump cavity shell 11 made of metal plate is separated.
In conjunction with shown in Fig. 2 and Fig. 3,3 bottom of compression pump is set there are four spring 4, and 4 one end of spring is fixed on compression pump 3, separately
One end is fixed at the top of compression pump cavity shell 11 inner wall, is suspended on compression pump 3 in compression pump housing 1, compression pump 3 when operation
Vibration absorbs a part by spring 4, reduces the generation of noise, and compression pump 3 does not connect with compression pump cavity shell 11 or 6 hardness of bottom plate
Touching, compression pump cavity shell 11 or bottom plate 6 will not generate resonance because of the vibration of compression pump 3, reduce noise.
Air inlet module is equipped in air inlet cavity 2, air inlet module delivers gas in compression pump 3, air inlet cavity shell 21 with
Compression pump cavity shell 11 is fixedly connected.
21 inner wall of air inlet cavity shell is pasted with puigging in the present embodiment, in compression pump cavity shell 11 and compressor case 5
Wall is also pasted with puigging, and puigging is made of three layers of different quieter material, respectively for different scale carry out noise reduction every
Independent noise reduction is carried out from and to the noise that different cavitys generate.
The surrounding of compression pump housing 1 and air inlet cavity 2 is assembled by metal plate housing, and noise will not be propagated from.Pressure
The noise that contracting pump housing 1 releases, then noise reduction again is carried out by the puigging of compressor case 5.
The technical solution of the utility model is not limited to the various embodiments described above, all technologies obtained using equivalent replacement mode
Scheme is all fallen in the scope of protection of present invention.
