Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to enable those skilled in the art with reference to specification text
Word can be implemented according to this.
Low noise cleaner air exhausting device disclosed by the invention as shown in Figure 1, including inner housing 1, partition board 2 and outer housing 3,
Motor of dust collector is accommodated in the accommodating chamber among inner housing 1, and inner housing 1 and partition board 2 form the first silencing cavity 6, partition board 2 with
Outer housing 3 forms the second silencing cavity 7, wherein, the inner wall on the surface of inner housing 1, the surface of partition board 2 and outer housing 3 is designed with
Identical sound absorbing layer 5, sound absorbing layer 5 are bonded in the surface of inner housing 1, the surface of partition board 2 and outer housing 3 by resin of binding property
On inner wall.
Inner housing 1 and partition board 2 are mounted in outer housing 3, by the complicated cumbersome electricity of the dust catcher of traditional technology
The assembling of machine inner cover becomes simple, and reduce the quantity of parts, and installation steps are few and simple in structure, while does not need to carry out more
Secondary installation, and it is easy to disassemble installation and be hardly damaged, prevented also from it is anti-loaded the problem of.
With reference to figure 1 and Fig. 2, the vent 4 of inner housing 1, partition board 2 and outer housing 3 is arranged to circumferentially staggered, and vent 4 is
It four and is uniformly equally spaced, circumferentially staggered vent limits the channel of gas flowing, in the air-flow that motor generates passes through
The vent of housing 1 enters the first silencing cavity 6, and can be flowed, and can be from the air draft on 2 side wall of partition board in the first silencing cavity 6
Hole 4 is discharged, and into the second silencing cavity 7, and can equally be flowed in the second silencing cavity 7, the vent most afterwards through 3 side wall of outer housing
It discharges outside outer housing 3, the noise generated when wherein gas flows, in the sound absorbing layer from 1 both sidewalls of intracavitary route inner housing
5th, during the sound absorbing layer 5 of 3 madial wall of the sound absorbing layer 5 of 2 both sidewalls of partition board and outer housing, the sound wave of noise is by cutting gradually
Weak absorbing achievees the purpose that noise reduction.
The vent 4 of inner housing 1, partition board 2 and outer housing 3 is arranged to be uniformly distributed circumferentially, and leads to so as to increase air-flow
The development length in road, and then increase flow of the air-flow in gas channel, further to strengthen the weakening and absorption to noise.
The upper outside edge of outer housing 3 is set there are four buckle 8, and in being provided at circumferentially spaced, buckle 8 is suitable for and dust suction
The upper cover of device snaps connection, convenient for the air exhausting device of dust catcher and the assembling of motor upper cover.
The sound absorbing layer includes the material of following parts by weight：
Its manufacturing process is as follows：
(1) polypropylene fibre of 50-60 parts by weight is supplied to the first roller first with roll squeezer；
(2) and then by the glass fibre of 35-40 parts by weight it is supplied to the second roller；
(3) it is the polyvinyl alcohol of 8-10 polyester fibers, the bombax cotton of 5-8 parts by weight and 5-7 parts by weight is uniform, it will
Mixture is supplied between the first roller and the second roller；
(4) due to the backward pull between the first roller and the second roller, the fibrous material above two rollers is mingled with polyester fiber, poly-
Propylene and polyvinyl alcohol and combine, be made the non-woven fabrics sound-absorbing material needed for this case, control thickness is 0.3-0.7mm.
Traditional handicraft mostly produces sound-absorbing material, but these materials are in itself with the polyester of gas permeable polymers or mineral wool etc.
Possessed physical property and gas permeability are general, and manufacturing process is cumbersome, the sound absorption qualities susceptible of sound-absorbing material, if
Attracting performance to improve material uses thicker sound-absorbing material, then can occupy limited use space, increase in dust catcher
The design cost in portion.
Compared with prior art, the present invention is added with the polyvinyl alcohol of 5-7 parts by weight during remanufacturing sound-absorbing material.
In the case that the content of glass fibre is less than 35 parts by weight, the physical properties such as tensile strength, the tearing strength of non-woven fabrics can be made
Decline, however in the case that the content of glass fibre is more than 40 parts by weight, and can but sound-absorbing material excessive due to gas permeability
Sound absorption qualities decline, and the binding force of glass fibre and polypropylene fibre is not strong under normal circumstances, but when adding in polyvinyl alcohol
Afterwards, glass fibre can be promoted to be combined with polypropylene fibre more secured, is not easy layering and is detached from, currently preferred glass fibers
Dimension hplc be 35-40 parts by weight, within this range, with polypropylene fibre collective effect can be promoted sound-absorbing material tensile strength and
Tear resistance, and sound-absorbing material thickness obtained is moderate, sound absorption qualities are remarkable.
