Description

A kind of oxygenerator is with multi-functional integrated exhaust box

Technical field

The utility model relates to the muffling device technical field, and particularly a kind of oxygenerator is with multi-functional integrated exhaust box.

Background technology

The miniaturization of and product ripe along with PSA (absorption of Pressure Swing Adsorption-transformation) oxygenerating technology, and the noise during induction noise and the toxic emission of air compressor when air-breathing is quite big, influences user's comfort level.And for reducing noise, conventional way is to increase small product size, and installation noise reduction as much as possible is cotton, and this method has following shortcoming: 1. volume big-subsides noise reduction as much as possible cotton, 2. cost high-relatively costliness and consumption are many for efficient acoustical cotton; 3. the cotton technology of complex process-paste at present noise reduction can't robotization, can only manual operations, and current human cost increases severely and causes cost to rise indirectly; 4. eliminating the noise cotton also is thermal insulation material simultaneously, therefore can make the heat in the machine be difficult for shedding, and will strengthen the power consumption of exhaust fan again.

The utility model content

The utility model provide a kind of simple in structure, materials are few, assembling is simple, the space-efficient oxygenerator is with multi-functional integrated exhaust box.

To achieve these goals, the utility model provides following technical scheme:

A kind of oxygenerator is with multi-functional integrated exhaust box, and it comprises:

Inner bag and shell; Said inner bag is provided with two difunctional gas ports that are used for air inlet or give vent to anger, and the gas port set inside of said inner bag at the center has concentrically ringed first phase-reversing tube and second phase-reversing tube, and said first phase-reversing tube is positioned at the outside of said second phase-reversing tube; The outer rim of said inner bag is provided with the first locking tenon position; The inner edge of said shell is provided with the second locking tenon position, and said enclosure is provided with go back to the palace, said time an O shape O-ring seal and gas filtration core is housed in palace; Said first locking tenon position and the said second locking tenon position are fastened togather; Said gas filtration core retainer plate is on first phase-reversing tube of inner bag, and an end of said gas filtration core is against on the inwall of inner bag, and the other end of said gas filtration core is against on said time O shape O-ring seal in utero.

Preferably, the outer rim of said inner bag is provided with seal groove, and the 2nd O shape O-ring seal is housed on the said seal groove, and said the 2nd O shape O-ring seal is between said shell and said inner bag.

Through implementing above technical scheme; Have following technique effect: the oxygenerator that the utility model provides utilizes time palace structure of the concentric circles phase-reversing tube and the shell of inner bag with multi-functional integrated exhaust box, and the structure of adjusting go back to the palace produces ascending gradual change air gap; Can the conversion of low frequency gas shock sound be the unheard high frequency sound of people's ear when utilizing high velocity air through minimum air gap; And, promptly reach the purpose of eliminating pneumatic noise through inner high frequency noise reduction, simultaneously the high frequency segment is designed at innermost layer; And, finally reach the purpose of noise reduction through the inner counter receipts of reverting to take drugs.The method that connects difference during according to use, can do being used in respectively: intake noise reduction, inlet air filtration, three kinds of positions of exhausting silencer, and when air intake filter uses, then can conveniently pull down and take out the gas filtration core, cleaning or replacing gas filtration core.Structure is very simple, and materials are few, the assembling simple, save space.

Embodiment

In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

The utility model embodiment provides a kind of oxygenerator with multi-functional integrated exhaust box, and is as shown in Figure 1, comprising:

Inner bag 109 and shell 108, this inner bag 109 is cylindrical structure with shell 108, and said inner bag 109 is provided with two difunctional gas ports that are used for air inlet or give vent to anger; Comprise first gas port 104 and second gas port 105, this difunctional gas port is meant that under certain conditions first gas port is as air intake opening; Second gas port is as the gas outlet, and under other situation, first gas port is as the gas outlet; Second gas port is as air intake opening, and the gas port set inside of said inner bag at the center has concentrically ringed first phase-reversing tube 110 and second phase-reversing tube 111, and said first phase-reversing tube 110 is positioned at the outside of said second phase-reversing tube 111; The outer rim of said inner bag 109 also is provided with the first locking tenon position 103; The inner edge of said shell 108 is provided with the second locking tenon position 107, and said shell 108 set inside have go back to the palace, and promptly the set inside of this shell 108 has two cylinders that vary in size; And two cylinders are same position with the center of circle of circular shell 108, and two cylinders form go back to the palace.The one O shape O-ring seal 106 and gas filtration core 102 in palace are housed for said time, and the said first locking tenon position 103 is fastened togather with the said second locking tenon position 107, shell 108 and inner bag 109 rotations are interlocked and locks.Said gas filtration core 102 is enclosed within on first phase-reversing tube of inner bag 109; One end of said gas filtration core 102 is against on the inwall of inner bag; The other end of said gas filtration core 102 is against on said time O shape O-ring seal 106 in utero; The elasticity of a said O shape O-ring seal 106 pushes against gas filtration core 102 and reaches inner chamber and exocoel isolation, to reach the effect of noise reduction.That utilizes two concentric circles phase-reversing tubes and shell on the inner bag returns the palace structure; The structure of adjusting go back to the palace produces ascending gradual change air gap, can the conversion of low frequency gas shock sound be the unheard high frequency sound of people's ear when utilizing high velocity air through minimum air gap, and through inner high frequency noise reduction; Promptly reach the purpose of eliminating pneumatic noise; Simultaneously with high frequency segment design at innermost layer, and, finally reach the purpose of noise reduction through the inner counter receipts of reverting to take drugs.Like Fig. 3 and shown in Figure 4, the method that the connects difference during according to use can do being used in respectively: intake noise reduction, inlet air filtration, three kinds of positions of exhausting silencer; And when air intake filter uses; Then can conveniently pull down and take out the gas filtration core, clean or changed the gas filtration core, structure is very simple.
