Description
Technical field
The present invention 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.
Summary of the invention
In order to solve the problems in the existing technology the present invention, provides a kind of noise reduction knot of the compressor of good muffling effect
Structure.
In order to achieve the above object, technical solution proposed by the present invention are as follows: a kind of noise-reducing structure of compressor, the compression
Machine includes compressor case, bottom plate and compression pump, be equipped in compressor case the air inlet cavity being separated by air inlet cavity shell and
The compression pump housing being separated by compression pump cavity shell, the air inlet cavity shell and compression pump cavity shell it is fastened to each other connection and
It is fixed on bottom plate, compressor case covers on air inlet cavity shell and compression pump cavity shell, and the compression pump hangs on compression pump
In cavity.
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 noise reduction layer is made of three layers of different quieter material.
The invention has the benefit that
Compression pump, which is set, in the present invention is suspended in compression pump housing, so that the maximum noise source of compression pump, by being enclosed in independence
The intracavitary elimination of compression pump-type, while compression pump not with compression pump cavity shell or bottom plate fixation contact, can be reduced compression pump operation
Bring resonance noise.
Compression pump is set in independent compression pump housing in the present invention, the air inlet module of compression pump be set to it is independent into
In air cavity, be equipped in compression pump housing, air inlet cavity and compressor case by three layers of different acoustic material form every
Sound-absorbing layer carries out noise reduction isolation for different scales.
Detailed description of the invention

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 noise reduction layer 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.
Technical solution of the present invention is not limited to the various embodiments described above, all technical solutions obtained using equivalent replacement mode
It all falls in the scope of protection of present invention.
