The utility model provides a new trend noise damper, simple to operate through the noise in the partial release pipeline in advance, can reduce the noise in the air outlet greatly.
Description
Technical Field
The utility model relates to a new trend technical field of system, more specifically the new trend noise damper that says so.
Background
In the new trend system, the mode that adopts the amortization ripples hose at the fan front end at present usually reduces the noise and passes through the pipeline and propagate to indoorly, but the noise effect that reduces the air outlet is unsatisfactory, and the new trend still can produce the noise of regeneration in pipeline and connecting pipe fitting transportation process moreover.
SUMMERY OF THE UTILITY MODEL
The utility model provides a new trend noise damper to solve the problem in the background art.
In order to realize the purpose, the utility model adopts the following technical scheme:
a fresh air noise damper comprising: the inclined cross joint comprises a straight pipeline, a first inclined pipeline and a second inclined pipeline which are respectively arranged on two sides of the straight pipeline, the straight pipeline is respectively communicated with the first inclined pipeline and the second inclined pipeline, and an included angle between the straight pipeline and the first inclined pipeline and an included angle between the straight pipeline and the second inclined pipeline are acute angles; the end covers are respectively arranged at the openings of the first inclined pipeline and the second inclined pipeline, and a plurality of through holes are formed in the end covers; the dustproof and antibacterial film is arranged on the end cover.
In some embodiments, the through holes are equally spaced in an annular array.
In some embodiments, the included angle between the straight pipeline and each of the first inclined pipeline and the second inclined pipeline is 30-45 degrees.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
On the contrary, this application is intended to cover any alternatives, modifications, equivalents and variations that may be made within the spirit and scope of the present application as defined by the appended claims. Furthermore, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. It will be apparent to one skilled in the art that the present application may be practiced without these specific details.
FIG. 1 is a schematic structural view of a fresh air noise damper according to some embodiments of the present application; FIG. 2 is a schematic view of the connection between the end cap 3 and the dust and bacteria proof membrane of the fresh air noise damper according to some embodiments of the present application; FIG. 3 is a top view of the end cap 3 of the fresh air noise damper according to some embodiments of the present application; the fresh air noise damper according to the embodiment of the present application will be described in detail with reference to fig. 1 to 3. It is to be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.
In an embodiment of the present application, as shown in fig. 1-3, the fresh air noise damper may include: the dustproof and antibacterial anti-bacterial four-way joint comprises a straight pipeline 1, a first inclined pipeline 2 and a second inclined pipeline 5 which are respectively arranged on two sides of the straight pipeline 1, wherein the straight pipeline 1 is respectively communicated with the first inclined pipeline 2 and the second inclined pipeline 5, and an included angle between the straight pipeline 1 and the first inclined pipeline 2 and an included angle between the straight pipeline 1 and the second inclined pipeline 5 are acute angles; the end cover 3 is respectively arranged at the mouth parts of the first inclined pipeline 2 and the second inclined pipeline 5, and a plurality of through holes are formed in the end cover 3; the through holes are arranged in an annular array at equal intervals. The dustproof and antibacterial film is arranged on the end cover 3.
After the dustproof and antibacterial film is placed at a proper position of the end cover 3, the end cover 3 is inserted into a socket of the inclined cross to compress the dustproof and antibacterial film, and the structure is convenient for later replacement; according to the wind direction indication above the oblique cross at suitable position installation noise attenuator, according to the minimum principle of damping, wind directly flows to the front end, can not flow from first inclined pipeline 2 and the second inclined pipeline 5 on both sides basically, pipeline system's air volume has effectively been guaranteed, but noise in the pipeline can be followed first inclined pipeline 2 and the second inclined pipeline 5 end cover 3 department partial release outside the pipeline, noise in the pipeline system has effectively been reduced, thereby the noise of indoor air outlet has been reduced, owing to there be dustproof fungi-proofing membrane, can avoid in the external dust of pipeline and germ get into the new trend pipe-line system, guarantee the new trend health in the system.
In some embodiments, the angle between the straight duct 1 and the first and second angled ducts 2, 5, respectively, is an acute angle of 30 ° to 45 °, preferably 45 °.
The beneficial effects that the new trend noise attenuator that this application disclosed probably brings include but not limited to: the new trend noise damper that this embodiment provided, simple to operate through the inside partial noise of release tube in advance, can reduce the noise of going out indoor air outlet greatly.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
