The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Fig. 1 is the perspective view of the utility model preferred embodiment muffler, Fig. 2 is that the connection diagram of the utility model preferred embodiment muffler and blast pipe (is only connection diagram, do not limit the structure of muffler), Fig. 3 is the structural representation of spiral spring plate in the utility model preferred embodiment muffler.
With reference to Fig. 1, Fig. 2 and Fig. 3, the muffler that this embodiment proposes, comprise the noise reduction pipeline section 10 being arranged on blast pipe 30 and be located in noise reduction pipeline section 10 and the spiral spring plate 20 coaxial with noise reduction pipeline section 10, one end of noise reduction pipeline section 10 is provided with the air inlet 11 for being tightly connected with blast pipe 30, the other end of noise reduction pipeline section 10 is provided with the gas outlet 12 for being tightly connected with blast pipe 30, and the outer side edges 21 of spiral spring plate 20 is fixedly connected with the medial surface of noise reduction pipeline section 10.
With reference to Fig. 1-3, the muffler of the present embodiment, in figure, A is air flow direction, air-flow enters noise reduction pipeline section 10 from air inlet 11, because the internal diameter of noise reduction pipeline section 10 is greater than the internal diameter of blast pipe 30, so the air pressure of air-flow and speed reduce.Meanwhile, disorderly airflow function is on the shell fragment face 22 of spiral spring plate 20, and 22 deformation of shell fragment face cushion air-flow, further reduce the speed of air-flow; Shell fragment face 22 links the active force of the air-flow being subject to be distributed on whole spiral spring plate 20 by deformation, then by spiral spring plate 20, this active force is reached on the medial surface of whole noise reduction pipeline section 10, makes medial surface mean forced on noise reduction pipeline section 10; And the air-flow part near noise reduction pipeline section 10 medial surfaces leads through spiral spring plate 20, forms along the mobile helical airflow passages of spiral spring plate 20, finally 12 outflows from gas outlet.Effectively solve the amplitude problems of too that disorderly air-flow causes noise reduction pipeline section 10 medial surface active force inequalities, better reached erasure effect, avoided the situation of blast pipe 30 with the resonance of compressor or miscellaneous part.
According to the principle of active force and reaction force, the obstruction power of 22 pairs of air-flows of shell fragment face of spiral spring plate 20 is excessive, the noise reduction pipeline section 10 of muffler bears along the power of its axial direction just greatlyr, easily like this causes noise reduction pipeline section 10 to be pulled off and disconnects with blast pipe 30, and then cause system leak.Generation for fear of this situation, the spiral spring plate 20 that the present embodiment adopts, the angle that the medial surface of its shell fragment face 22 and noise reduction pipeline section 10 forms be opening towards gas outlet 12 acute angles, the inclination of shell fragment face 22 is just along airflow direction like this, can play buffering and guide effect, the obstruction power of 22 pairs of air-flows of shell fragment face can be not excessive yet, can guarantee the trouble free service of muffler.
In order to guarantee that spiral spring plate 20 is connected with the firm of noise reduction pipeline section 10, the present embodiment preferably adopts the mode of welding that the outer side edges of spiral spring plate 20 21 is fixed on the medial surface of noise reduction pipeline section 10.Certainly, spiral spring plate 20 can also adopt other fixed forms with the fixing of noise reduction pipeline section 10.
Further, traditional muffler is because its noise reduction pipeline section outlet side face (being provided with one end of gas outlet 12) is varied down to suddenly identical with blast pipe 30 internal diameters by larger internal diameter, therefore can make air-flow velocity increase suddenly, airflow strikes is large in the impact of the end of giving vent to anger, cause this place's amplitude excessive, be easy to cause noise reduction pipeline section or blast pipe to be pulled off, thereby cause system leak.
And the noise reduction pipeline section 10 of the present embodiment comprises straight length 13 and gradual change pipeline section 14, air inlet 11 is located at the first end of straight length 13, and straight length 13 second ends dock with the first end of gradual change pipeline section 14, and the second end of gradual change pipeline section 14 is located in gas outlet 12; The internal diameter of gradual change pipeline section 14 is diminished to its second end gradually by its first end, and the internal diameter that the internal diameter of the spiral spring plate 20 at this place is also followed gradual change pipeline section 14 certainly reduces.By gradual change pipeline section 14, noise reduction pipeline section 10 is diminished gradually near the internal diameter of one end of gas outlet 12, air-flow is formed to a transition buffer effect, effectively solved the excessive and problem that the noise reduction pipeline section 10 that causes or blast pipe 30 are pulled off of airflow strikes power.
Straight length in the present embodiment 13 can be formed in one with gradual change pipeline section 14, can also be spirally connected by sealing, the mode such as welding docks.
Further, because the Main Function of gradual change pipeline section 14 is the effects to air-flow transition buffer, its sound deadening does not have the effect of straight length 13 large, in order to guarantee the erasure effect of muffler, the length of the present embodiment gradual change pipeline section 14 is set to be less than the length of straight length 13, and straight length 13 can be determined according to actual demand with the length ratio of gradual change pipeline section 14 certainly.
Further, consider the preferably trouble free service situation of buffering effect and noise reduction pipeline section 10 of 20 pairs of air-flows of spiral spring plate, the angle that the present embodiment preferably adopts the shell fragment face 22 of spiral spring plate 20 and the medial surface of straight length 13 to form is 45 °, while so being also convenient to produce, the layout of spiral spring plate 20 and with being welded and fixed of noise reduction pipeline section 10.
The utility model also proposes a kind of air-conditioner, comprises muffler, and this muffler can comprise the technical scheme of above-mentioned arbitrary embodiment, and its detailed structure can be with reference to above-described embodiment, and therefore not to repeat here.Owing to having adopted the scheme of aforementioned muffler, therefore air-conditioner of the present utility model is compared to existing air-conditioner, and its noise is less, more environmental protection; The security of blast pipe each parts is around better simultaneously.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
