The muffler comprises an upper cover, a lower cover, bottom pins and a middle sealing structure and is characterized in that the upper cover and the lower cover are respectively and fixedly connected with the top part and the bottom part of the middle sealing structure; the bottom pins are welded with the lower part of the middle sealing structure; the middle sealing structure consists of an outer wall, an inner wall and a flow-choking porous tube; the inner wall is arranged inside the outer wall and is fixed by a support frame; the flow-choking porous tube is arranged inside the inner wall and is fixedly connected with the lower cover; a first sound absorption chamber is formed between the flow-choking porous tube and the inner wall; a second sound absorption chamber is formed between the inner wall and the outer wall; both the outer wall and the inner wall consist of seamless steel tubes and soundproofing porous tubes; and soundproofing cottons are filled between the seamless steel tubes and the soundproofing porous tubes. Compared with the prior art, the utility model has the characteristics that the muffler matched with the oxygen concentrator has low cost, good soundproofing effect and long service life and has the functions of soundproofing and exhausting, and manufacture materials are easy to purchase, etc.
Description
Technical field
The utility model relates to the medical equipment technical field, specifically a kind of sound suppressor that is matched in oxygen concentrator.
Background technology
Sound suppressor is to stop sound transmission and a kind of device of allowing air communication to cross, is the important measures of eliminating air power noise.Sound suppressor is mounted on the gas channel of aerodynamic force equipment (as fan blower, air compressor machine) or the device of the reduction noise in the inlet and exhaust system.Sound suppressor can stop the propagation of sound wave, allows the air communication mistake, is the effective tool of control noise.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the mode that adopts a kind of sound wave to offset is used for the sound suppressor that links to each other with oxygen concentrator, has solved the existing sound suppressor halfway problem of eliminating the noise.
In order to achieve the above object, the utility model provides a kind of sound suppressor that is matched in oxygen concentrator, comprise loam cake, lower cover, footing, middle part sealing structure, it is characterized in that: the top and the bottom of part sealing structure during loam cake and lower cover are fixedlyed connected respectively, footing is welded to connect the bottom at middle part sealing structure, middle part sealing structure is by outer wall, inwall and choked flow antipriming pipe are formed, inwall places the inside of outer wall and adopts bracing frame to fix, the choked flow antipriming pipe places the inside of inwall and fixedlys connected with lower cover, form first anechoic room between choked flow antipriming pipe and the inwall, form second anechoic room between inwall and the outer wall; Described outer wall and inwall all for being made up of weldless steel tube, noise elimination antipriming pipe, are filled with acoustical cotton between weldless steel tube and the noise elimination antipriming pipe; Described loam cake bottom and following tops are equipped with sieve plate, are equipped with acoustical cotton between sieve plate and loam cake, the lower cover; Described bracing frame is fixedly connected on the sieve plate.
Be covered with air intake opening under described, on be covered with exhausr port.
The utility model is compared with prior art, has cheaply, and it is effective to eliminate the noise, and long service life, manufacturing materials are purchased and easily with eliminating the noise and characteristics such as degassing function.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is loam cake; 2 is lower cover; 3 is footing; 4 are the choked flow antipriming pipe; 5 is bracing frame; 6 is first anechoic room; 7 is second anechoic room; 8 is weldless steel tube; 9 are the noise elimination antipriming pipe; 10 is acoustical cotton; 11 is sieve plate; 12 is air intake opening; 13 is exhausr port.
Embodiment
Now in conjunction with the accompanying drawings the utility model is described further.
Referring to Fig. 1, the utility model comprises loam cake, lower cover, footing, middle part sealing structure.The top and the bottom of part sealing structure during loam cake 1 and lower cover 2 are fixedlyed connected respectively, footing 3 is welded to connect the bottom at middle part sealing structure, middle part sealing structure is made up of outer wall, inwall and choked flow antipriming pipe 4, inwall places the inside of outer wall and adopts bracing frame 5 fixing, choked flow antipriming pipe 4 places the inside of inwall and fixedlys connected with lower cover 2, form first anechoic room 6 between choked flow antipriming pipe 4 and the inwall, form second anechoic room 7 between inwall and the outer wall; Outer wall and inwall all for being made up of weldless steel tube 8, noise elimination antipriming pipe 9, are filled with acoustical cotton 10 between weldless steel tube 8 and the noise elimination antipriming pipe 9; Loam cake 1 bottom and lower cover 2 tops are equipped with sieve plate 11, are equipped with acoustical cotton 10 between sieve plate and loam cake 1, the lower cover 2; Bracing frame 5 is fixedly connected on the sieve plate 11; Lower cover 2 is provided with air intake opening 12, and loam cake 1 is provided with exhausr port 13.
Air intake opening 12 of the present utility model links to each other by pipeline with the nitrogen exhausr port of oxygen concentrator, and gas is entered in the chamber from oxygen concentrator, flows to first anechoic room 6 and second anechoic room 7 respectively through choked flow antipriming pipe 4, has formed the sound-absorbing container of continuous water conservancy diversion.The utility model is by means of the unexpected expansion of pipeline porous, nitrogen is discharged from exhausr port 13 through second anechoic room, 7 backs from first anechoic room 6, the noise waves of exhaust is just from interior past unofficial biography, but every cross section through first anechoic room 6 is expanded to second anechoic room 7 suddenly, because the further expansion of noise elimination antipriming pipe 9, make along the noise waves of pipe transmmision in sudden change place to the Sounnd source direction reflection with absorb, make the sound wave absorption of cancelling out each other, thereby reach the purpose of noise reduction.
