Description
Technical field
The invention belongs to oxygen producing equipment fields, and in particular to a kind of oxygenerator muffler.
Background technique
Oxygenerator is a kind of equipment for preparing oxygen using air separation technology, belongs to physical separation preparation method, specifically
For, it is the absorption property using molecular sieve, by physical principle, using huge discharge oilless (oil free) compressor as power, in air
Nitrogen separated with oxygen, finally obtain the oxygen of high concentration, such oxygenerator produces that oxygen is rapid, and oxygen concentration is high,
Suitable for various crowd's oxygen therapies and oxygen health care, and power consumption is low, and cost performance is high, still, due to existing oxygenerator use it is general
It is all mechanical valve type nitrogen oxygen separating, so very big moment noise can be generated in denitrogen gas, common 3 liters~5 liters oxygenerator institutes
The noise of generation will cause extremely strong sense of discomfort to people at 60 decibels or more.
Summary of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of oxygenerator exhaust that nitrogen discharge noise is effectively reduced
Muffler.
The present invention is achieved by the following technical solutions：
A kind of oxygenerator muffler, including inner core, housing, filter core and noise reduction seat, the inner core left side is air inlet,
Right part top closure, side are provided with several ventholes, are provided with baffle on the left of the venthole, the edge of the baffle with it is described
Closing connection, the housing axial direction inner wall post the first mute cotton on the left of housing, and right center is provided with through-hole, spiral shell in the through-hole
Line docking has the filter core, and the noise reduction seat is equipped on the outside of the filter core, is open on the left of the noise reduction seat, described in closed socket
Housing, right side are provided with several gas vents, and the noise reduction seat axial direction inner wall and the gas vent inner wall post the second mute cotton.
The baffle and the inner core are an entirety.
The first mute cotton and the second mute cotton use non-woven fabrics.
The inner core, housing and noise reduction seat use PP6 plastics or aluminium alloy.
The filter core uses PE sintered filter core.
Compared with prior art, the beneficial effects of the invention are as follows：Design of the invention is utilized cross-ventilation and buffers step by step
The principle of formula discharge, changes gas impact direction by inner core and filter core respectively, and the first mute cotton and second quiet is respectively adopted
Sound cotton sound-absorbing buffering, substantially reduces its discharge noise, improves the sense organ comfort level of user.

Specific embodiment
As in Figure of description Fig. 1 to a kind of oxygenerator muffler shown in Fig. 3, including inner core 1, housing 2, filter core
3 and noise reduction seat 4, it is air inlet 5 on the left of inner core 1, right part top closure, side one week is uniform to be provided with four discharge stomatas 6, venthole
6 left sides are provided with baffle 7, close and connect on the left of the edge and housing 2 of baffle 7, and the axial inner wall of housing 2 posts the first mute cotton 8,
Right center is provided with through-hole 9, and 9 internal screw thread of through-hole is equipped with noise reduction seat 4, opens on the left of noise reduction seat 4 to filter core 3 is connected on the outside of filter core 3
Mouthful, closed socket housing 2, right side is provided with several gas vents 10, and the axial inner wall of noise reduction seat 4 and 10 inner wall of gas vent post second
Mute cotton 11.
Wherein, baffle 7 and inner core 1 are an entirety.
Further, inner core 1, housing 2 and noise reduction seat 4 use PP6 plastics or aluminium alloy, and filter core 3 uses PE sintered filter core,
First mute cotton 8 and the second mute cotton 11 use non-woven fabrics.
Such as the working method of the invention that Fig. 4 is shown in Figure of description：Gas by being passed through air inlet 5 on the left of inner core 1,
Housing 2 is entered by venthole 6 again, enters filter core 3 through the first mute buffering of cotton 8, the gas filtered out by filter core 3 is again through noise reduction seat 4
Mute 11 buffering and sound-absorbing of cotton of the second of inner wall, is finally discharged by gas vent 10.
In conclusion only presently preferred embodiments of the present invention, is not used to limit the scope of implementation of the present invention, it is all according to
Equivalent changes and modifications carried out by shape described in scope of the invention as claimed, construction, feature and spirit should be included in this
In the scope of the claims of invention.
