Specific embodiment
In order that the purpose of invention, technical scheme and advantage become more apparent, below in conjunction with drawings and Examples, to this
Invention is further elaborated.
Embodiment
A kind of one of embodiment of air-blast device of respirator of the present invention, as shown in Figures 1 to 6, including be provided with into
The second housing 2 that first housing 1 in air port 11 is fixedly connected with the first housing 1, the first housing 1 and the second housing 2 form annular
Accommodating chamber, annular accommodating chamber is provided with air outlet 21；Annular accommodates intracavity and is provided with impeller 3 and baffle 4, and impeller 3 is installed on and turns
Axle and being driven by motor 7；First housing 1 and baffle 4 form the first air chamber 5, and impeller 3 is located at the first air chamber 5, baffle 4
Form the second air chamber 6 with the second housing 2, air outlet 21 is located at the second air chamber 6；Set between the outer of baffle 4 and the first housing 1
There is gap, during work, gas enters the first air chamber 5 from air inlet 11, enters the second air chamber by gap in the presence of impeller 3
6, finally flow out from air outlet 21；Specifically, the diameter of air inlet 11 can be set to 16-18mm, and the diameter of air outlet 21 is permissible
It is set to 14-16mm.Air chamber is divided into the first air chamber 5 and the second air chamber 6 by baffle 4, and the first air chamber 5 is inlet plenum, belongs to high pressure
Area, main generation radiated noise and conducted noise；Second air chamber 6 includes air outlet 21, assembles for air and compression is given vent to anger,
Belong to low-pressure area, mainly produce conducted noise, the noise in two after isolation air chamber interferes less, can effectively reduce
Radiated noise and conducted noise are it is easy to noise reduction.
Wherein, baffle 4 is provided with the boss 41 being connected with the first housing 1 at air outlet 21.Boss 41 connects
Baffle 4 at air port 21 and shell, for isolating the first air chamber 5 and air outlet 21, it is to avoid gas is without the second air chamber 6
Directly enter air outlet 21 from the first air chamber 5, serve the effect being effectively isolated, contribute to eliminating dynamic conducted noise.
Wherein, the height of boss 41 is 3～8mm.Preferably, the height of boss 41 is 5mm.Height of general boss 41 etc.
Gap between baffle 4 and the first housing 1, that is, gas from the first air chamber 5 flow into the second air chamber 6 circular passage width,
This gap is set to 5mm, is on the one hand conducive to gas to pass through, on the other hand contribute to isolating de-noising, after being test of many times
Optimum selection.
Wherein, impeller 3 includes integrally formed upper lid 31, lower cover 32, and is arranged between lid 31 and lower cover 32
Blade, upper lid 31 be provided centrally with air inlet 36, lower cover 32 includes lid and the axle sleeve perpendicular to lid；Blade includes enclosing
The first blade 33 being uniformly arranged around air inlet 36, and correspond with the first blade 33 and near lower cover 32 outer rim the
Two blades 34；It is provided with higher-pressure region gap 35 between the front end of the rear end of the first blade 33 and the second blade 34.Air-flow is from adjacent
Gap between one blade 33 enters, and a part is directly entered the gap between second adjacent blade 34；Another part then first leads to
Cross the higher-pressure region gap 35 between the first blade 33 and the second blade 34, then pass through the second blade 34.Air-flow is through effectively dividing
Stream is conducive to swimmingly flowing, and reduces radiated noise, flows into next region again after being especially that airflow through higher-pressure region gap 35,
Serve more effective erasure effect.
Wherein, upper lid 31 is gradually transitions peripheral edge from air inlet 36 in the way of radius of curvature becomes larger.Wherein,
The height of blade tapers into from front end to rear end.Upper lid 31 radius of curvature become larger, accordingly, then the first blade 33,
The height of the second blade 34 tapers into, and is equivalent to air-flow and enters in a large number, more slowly flows out impeller 3, decreases air-flow too precipitate labor
Raw conducted noise, serves sound deadening.
Wherein, the first blade 33 and the second blade 34 are circular arc vane.The blade of circular arc can make to play water conservancy diversion
Effect, reduce the irregular flow directions such as the backflow of wind, vortex, and then reduce resistance and the air pressure of wind, enabling subtract
Few conducted noise, further functions as erasure effect.
Wherein, the length of the first blade 33 is the twice of the length of the second blade 34.Throughput between the first blade 33 is relatively
Greatly, need the longer water conservancy diversion time, the twice that the length of the first blade 33 is arranged to the second blade 34 length is through multiple
Test obtains optimum, can reach best erasure effect using this ratio.
Wherein, impeller 3 is plastic ＆ rubber blade.The material of impeller 3 selects plastic cement material, can mitigate the quality of respirator, and
And it is more safe and reliable.
This air-blast device structure is simple, can eliminate radiated noise and conducted noise, good muffling effect simultaneously.
Finally it should be noted that above example is merely to illustrate technical scheme rather than the present invention is protected
The restriction of scope, although being explained in detail to the present invention with reference to preferred embodiment, those of ordinary skill in the art should manage
Solution, technical scheme can be modified or equivalent, without deviating from technical solution of the present invention essence and
Scope.
