The muffler has the advantages of small volume, convenient and flexible use, easy manufacturing and the like; and the test indicates that the mini-type muffler has relatively small resistance and better noise elimination effect.
Description
Technical field
The present invention relates to a kind of silencer that can reduce the noise that causes because of gas, particularly a kind of miniature silencer that can reduce the noise that causes because of gas.This device is particularly suitable as the silencing apparatus of micropump.
Background technique
Existing silencing apparatus, based on resistance noise reduction and (or) two kinds of basic fundamentals of reactive muffling.In actual applications, the reactive muffler volume is big, takes up space, and being not suitable for micropump needs the little requirement of volume.Dissipative muffler is because big to gas-flow resistance, and what have also needs inner matter, influences the service behaviour of pump.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing silencing apparatus and be not suitable for use in the shortcoming that micropump is eliminated the noise, and a kind of mini-type muffler is provided, make it can obviously reduce volume and resistance, and convenient the use, manufacture cost is lower, it is effective to eliminate the noise, and is applicable to the noise elimination of micropump class.
The present invention has adopted following technological scheme.
A kind of mini-type muffler comprises the chamber that is surrounded by shell, it is characterized in that: also comprise the first pipe pipe that is positioned at chamber interior, manage and be positioned at the first pipe outer tube of chamber outside in second pipe, the second pipe outer tube; The pipe and the first pipe outer tube interconnect in first pipe, and the pipe and the second pipe outer tube interconnect in second pipe; Wherein the first pipe outer tube has the air inlet port, and first pipe of pipe is given vent to anger in first pipe, and the second pipe air inlet port of pipe all is communicated with chamber in the port and second pipe, and second manages outer tube has the port of giving vent to anger.
First pipe is given vent to anger port in the outlet side that guarantees under the unimpeded prerequisite of air-flow as far as possible near chamber, and the second pipe air inlet port is at the inlet end that guarantees under the unimpeded prerequisite of air-flow as far as possible near chamber.
The first pipe outer tube and the second pipe outer tube can all be bending tubes.Also can adopt bending tube by the first pipe outer tube, the second pipe outer tube adopts straight tube.Also can adopt straight tube by the first pipe outer tube, the second pipe outer tube adopts bending tube.Can also first pipe outer tube and the second pipe outer tube all adopt straight tube.
Good effect of the present invention is: be deep into length long enough in the chamber as first pipe of suction tude, its port of giving vent to anger is in the outlet side that guarantees as far as possible close chamber under the unimpeded prerequisite of air-flow, and being deep into also long enough of length in the chamber as second pipe of steam outlet pipe, its air inlet port is at the inlet end that guarantees under the unimpeded prerequisite of air-flow as far as possible near chamber.The outstanding feature of this design is, guaranteed sufficiently long flow process of air-flow and erasure effect preferably under the less prerequisite of device overall volume.
It is little that the present invention has a volume, easy to use flexibly, advantage such as easy to manufacture.Test shows that its resistance is less, the noise elimination better effects if.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the invention.
Fig. 2 is the structural representation of second embodiment of the invention.
Fig. 3 is the structural representation of third embodiment of the invention.
Fig. 4 is the structural representation of fourth embodiment of the invention.
Embodiment
Further specify the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this example comprises the chamber 2 that is surrounded by shell 1.The shape of described chamber 2 can be cylindric, also can be cuboid or cube-shaped, can also be other shape.Also comprise pipe 6 and the first pipe outer tube, 3, the second pipe outer tubes 5 that are positioned at chamber 2 outsides in first pipe, 4, the second pipes that are positioned at chamber 2 inside.The pipe 4 and first pipe outer tube 3 interconnects in first pipe, and the pipe 6 and second pipe outer tube 5 interconnects in second pipe.Wherein the first pipe outer tube 3 first pipe that has a pipe 4 in air inlet port 7, the first pipe is given vent to anger, and the second pipe air inlet port 10 of pipe 6 all is communicated with chamber 2 in the port 8 and second pipe, and second manages outer tube 5 has the port 9 of giving vent to anger.
First pipe is given vent to anger port 8 in the outlet side that guarantees under the unimpeded prerequisite of air-flow as far as possible near chamber 2, i.e. right-hand member among the figure, and the second pipe air inlet port 10 is at the inlet end that guarantees under the unimpeded prerequisite of air-flow as far as possible near chamber, i.e. left end among the figure.
Air-flow enters the first pipe outer tube 3 from the air inlet port 7 of the first pipe outer tube 3, leads in first pipe pipe 4 and flows out and enter chamber 2 from first pipe port 8 of giving vent to anger.Because the disconnected sectional area of chamber 2 substantially exceeds the disconnected sectional area of pipe 4 in first pipe, air-flow flows out the back diffusion of expanding rapidly from first pipe port 8 of giving vent to anger.The gas that flows into chamber 2 enters pipe 6 in second pipe from the second pipe air inlet port 10 again.Because the disconnected sectional area of pipe 6 is significantly smaller than the disconnected sectional area of chamber 2 in second pipe, shrink rapidly so enter the gas of pipe 6 in second pipe.The air-flow second pipe outer tube 5 of flowing through at last enters atmosphere from the port 9 of giving vent to anger, the diffusion of expanding rapidly in atmosphere.In said process, gas expands through expand---contraction---, the big high attenuation of noise energy, thus reach the noise elimination purpose.
Wherein, the first pipe outer tube 3 and the second pipe outer tube 5 can all be bending tubes, such as 90 ° of bending tubes, and shown in Figure 4 as the 4th embodiment.Also can first pipe outer tube 3 adopt bending tubes, the second pipe outer tube 5 adopts straight tubes, shown in Figure 1 as first embodiment.Also can first pipe outer tube 3 adopt straight tubes, the second pipe outer tube 5 adopts bending tubes, shown in Figure 3 as the 3rd embodiment.Can also first pipe outer tube 3 and the second pipe outer tube 5 all adopt straight tube, shown in Figure 2 as second embodiment.
