Abstract
The invention relates to a silencer. By aiming at the problems that the structure of the existing silencer is complicated, and the use is inconvenient, the invention provides the silencer capable of perfectly solving the problems. The goal is realized through the following scheme that the silencer comprises a wind box 1, wherein one end of the wind box 1 is connected with an air outlet pipe 4, a connecting part of the air outlet pipe 4 and the wind box 1 is a small opening 2 with the diametersmaller than the diameter of the air outlet pipe 4, and a loop-shaped passage 3 is arranged between the outer wall of the air outlet pipe 4 and the small opening 2. Through the arrangement of the loop-shaped passage in the air outlet pipe, the goal of silencing can be conveniently realized, the structure is simple, the normal passing of the wind is not influenced, and the popularization and the application are favorably realized.
Description
Technical field
The present invention relates to a kind of muffling device.
Background technique
Existing blower fan muffler structure is complicated, though have certain erasure effect, uses extremely inconvenient.
Summary of the invention
Have complex structure, inconvenient problem with use to present baffler, the present invention provides a kind of baffler, can address the above problem preferably.
Said purpose realizes through following scheme:
A kind of baffler comprises bellows 1, and an end of said bellows 1 connects air outlet tube 4, and said air outlet tube 4 is the osculum 2 less than air outlet tube 4 diameters with the joint of bellows 1, and back-shaped passage 3 is set between the outer wall of said osculum 2 and air outlet tube 4.
The present invention can conveniently realize the purpose of noise reduction through back-shaped passage is set in air outlet tube, it is simple in structure, does not influence the normal current of wind, is beneficial to and applies.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Wherein, bellows 1, osculum 2, back-shaped passage 3, air outlet tube 4.
Embodiment:
Set forth the preferred embodiment of the present invention in detail below in conjunction with accompanying drawing.
This mode of execution provides a kind of baffler; With reference to Fig. 1, comprise bellows 1, an end of said bellows 1 connects air outlet tube 4; Said air outlet tube 4 is the osculum 2 less than air outlet tube 4 diameters with the joint of bellows 1, and back-shaped passage 3 is set between the outer wall of said osculum 2 and air outlet tube 4.
This mode of execution is the protection domain that the exemplary illustration of this patent is not limited it; Those skilled in the art can also carry out the part to it and change; The short of spirit that exceeds this patent all is regarded as the replacement that is equal to this patent, all within the protection domain of this patent.
