Abstract
The utility model discloses a kind of bellows, it is characterised in that noise reduction layer is provided with the inwall of the bellows body, the outer wall of the noise reduction layer mutually agrees with the inwall of bellows, and the inwall of the noise reduction layer is smooth surface.By the above-mentioned means, the utility model bellows, can reduce caused noise during use, air channel efficiency is improved, reduces vibration.
Description
Technical field
Bellows field is the utility model is related to, more particularly to a kind of noise reduction bellows.
Background technology
On the blower for needing large rotation angle, generally require using bellows connection blowpipe guiding wind direction.In China
In patent CN205423213U, CN201510937396, bellows is as connecting fan and the necessaries of airduct, it is ensured that
Airduct has the larger anglec of rotation, however, to ensure that the rotatability of bellows, bellows is generally undulatory structure, its
Inwall is rough and uneven in surface, and when air flows through bellows, first air-flow can form turbulent flow herein, cause the loss of energy, secondly, air-flow
Disturbance can produce larger noise, influence the usage experience of operator, current bellows practical effect is undesirable, no
Use demand can be met.
The content of the invention
The utility model can be reduced caused by during use mainly solving the technical problems that provide a kind of bellows
Noise, air channel efficiency is improved, reduce vibration.
In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of bellows is provided, it is described
Noise reduction layer is provided with the inwall of bellows body, the outer wall of the noise reduction layer mutually agrees with the inwall of bellows, the noise reduction layer
Inwall be smooth surface.
In one preferred embodiment of the utility model, the thickness minimum value of the noise reduction layer is more than or equal to 4mm.
In one preferred embodiment of the utility model, the noise reduction layer is made up of silencing cotton or polyester fiber.
In one preferred embodiment of the utility model, the bellows body for rectangle, trapezoidal or corrugated ripple
Line.
In one preferred embodiment of the utility model, the noise reduction layer detachable is arranged on bellows body.
In one preferred embodiment of the utility model, the noise reduction layer is connected by foam process with bellows body.
In one preferred embodiment of the utility model, connected between the noise reduction layer and bellows body by filler
One.
In one preferred embodiment of the utility model, the bellows body is flexible material.
In one preferred embodiment of the utility model, the port of the bellows is bell mouth shape.
The beneficial effects of the utility model are：The utility model bellows, caused noise during use can be reduced,
Air channel efficiency is improved, vibration is low.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：
Fig. 1 is the structural representation of the preferred embodiment of the utility model bellows one；
Fig. 2 is the partial structural diagram of the bellows shown in Fig. 1；
Fig. 3 is the partial structural diagram of the bellows shown in Fig. 1；
The mark of each part is as follows in accompanying drawing：1st, bellows body, 2, port, 3, noise reduction layer, 31, noise reduction layer outer surface, 32,
Noise reduction layer inner surface.
Embodiment
The technical scheme in the embodiment of the utility model will be clearly and completely described below, it is clear that described
Embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
Referring to Fig. 1, a kind of bellows, including bellows body 1 and the port 2 for being connected to the both ends of bellows body 1, ripple
Noise reduction layer 3 is provided with the inwall of body 1.
In addition, the inner surface 32 of noise reduction layer 3 is smooth state, outer surface 31 is the ripple mutually agreed with ripple inside pipe wall
Shape.
In addition, it is more than or equal to 4mm at the minimum thickness of noise reduction layer 3.
In addition, noise reduction layer 3 is made up of silencing cotton or polyester fiber.
In addition, the position rectangle of bellows body 1, trapezoidal or corrugated ripple.
In addition, the detachable of noise reduction layer 3 is arranged on bellows body.
In addition, linked into an integrated entity between noise reduction layer 3 and bellows body 1 by filler.
In addition, bellows body 1 is flexible material.
In use, because bellows body 1 and noise reduction layer 3 are flexible material, curving for ripple had not both been interfered with so
Performance, it can also have the function that to reduce noise and turbulent flow.
Prior art is different from, the utility model bellows, caused noise during use can be reduced, improves air channel
Efficiency, vibration are low.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, similarly it is included in scope of patent protection of the present utility model.
