Description
Technical field
The utility model belongs to oxygenerator air inlet noise reduction technical field, and in particular to a kind of inlet air filtration silencing means.
Background technique
As consciousness of the people to itself health care gradually increases, many patients need regular or frequent oxygen uptake, to adjust body
The interior demand to oxygen, family health care type oxygenerator come into being, it gradually starts to substitute traditional small oxygen cylinder, although health care
The oxygenerator of type is developed, but there is also bigger disadvantages, that is, noise problem, currently, Miniature oxygenerator air inlet disappears
Sound is not only simple in structure, and erasure effect is poor, this problem is badly in need of solution using single filter cotton cotton layer and expansion silencing cavity
Certainly.
Summary of the invention
The purpose of this utility model is to provide a kind of inlet air filtration silencing means, to solve the erasure effect etc. of oxygenerator
Problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of inlet air filtration silencing means, including into
Gas drier, throttling silencer mechanism, the air inlet drier is by the dry filter layer of aluminium oxide and HEPA filter element filtering layer group
At the HEPA filter element filtering layer is set on the downside of the dry filter layer of aluminium oxide；The throttling silencer mechanism is by throttle valve adjustment
Knob, internal silencing cavity, air outlet adapter composition, the throttle valve adjustment knob are set to air inlet drier and throttling noise reduction machine
Structure junction, the internal silencing cavity are located on the downside of throttle valve adjustment knob, are provided with out on the downside of the throttle valve adjustment knob
Gas connector.
Preferably, the throttle valve adjustment knob is cone structure.
Preferably, the air inlet drier and throttling silencer mechanism are integrally formed.
The technical effect and advantage of the utility model: 1, the device is controlled by using air inlet dry filter and charge flow rate
And expanding chamber noise reduction, there is filtering erasure effect well；
2, it is reasonable in design, easy to operate, easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the process frame diagram of the utility model；
In figure: 1- air inlet drier；2- aluminium oxide dries filter layer；3-HEPA filter element filtering layer；4- throttling noise reduction machine
Structure；5- throttle valve adjustment knob；Silencing cavity inside 6-；7- air outlet adapter.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of inlet air filtration silencing means as shown in Figure 1 and Figure 2, including air inlet drier,
Throttle silencer mechanism, and the air inlet drier is made of the dry filter layer of aluminium oxide and HEPA filter element filtering layer, the HEPA
Filter element filtering layer is set on the downside of the dry filter layer of aluminium oxide；The throttling silencer mechanism is disappeared by throttle valve adjustment knob, inside
Sound chamber, air outlet adapter composition, the throttle valve adjustment knob are set to air inlet drier and throttling silencer mechanism junction, institute
It states internal silencing cavity to be located on the downside of throttle valve adjustment knob, is provided with air outlet adapter on the downside of the throttle valve adjustment knob.
Specifically, the throttle valve adjustment knob is cone structure.
Specifically, the air inlet drier and throttling silencer mechanism are integrally formed.
Working principle: outside air first passes through aluminium oxide dry filter and carries out micronic dust filtering using HEPA filter core, strictly
Control the safety of air inlet gas.Silencer mechanism 4 throttle by throttle valve adjustment knob 5, internal silencing cavity 6 and 7 groups of air outlet adapter
At.For gas after air inlet is dry, charge flow rate carries out Precise control by throttle valve adjustment knob, is meeting device specifications
In the case where to charge flow rate strict control, reduce flow it is bigger than normal caused by noise problem, after the control of throttle valve adjustment knob
Gas enter back into internal silencing cavity and carry out secondary noise reduction.Design is close reasonable, has very strong practicability, is suitble to promote.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
