Cylinder, the mainboard body are equipped with multiple main bloops, and motor stator passes through mainboard body, upward in rotor axis of electric: at outside plate ring
Between fan housing and noise reduction cylinder；
Noise reduction cylinder one end is fixed with outside plate ring, and noise reduction cylinder and rotor are coaxially arranged, and sound-absorbing is equipped in noise reduction cylinder
Cotton layer.
Preferably, the mainboard body is equipped with multiple secondary bloops, main noise reduction number of perforations is greater than secondary noise reduction number, any
The spacing of main bloop and rotor axis is greater than the spacing of any secondary bloop and rotor axis.
Preferably, each main bloop is circumferentially uniformly distributed along rotor, each pair bloop circumferentially divides along rotor
Cloth.
Preferably, the motor stator includes stator skeleton and multiple stator punchings connecting with stator skeleton, stator
Skeleton is equipped with multiple rubber bars, and rubber bar one end is connect with noise reduction cylinder, the rubber bar other end and stator bone
Frame connection.
Preferably, each rubber bar is circumferentially uniformly distributed along rotor, it is circumferentially upper in rotor: adjacent rubber
Noise reduction gap is formed between support rod.
Air draught and air draft are realized the beneficial effects of the utility model are: can effectively receive, and there is noise reduction, drop in the course of work
The function of making an uproar can effectively carry out noise reduction and local sound insulation, and noise is smaller when can ensure use；Have the function of resilient support, support
Part can play the function of support damping, elastic shock absorbing and sound-deadening and noise-reducing simultaneously, and whole vibration is small, noise is small, long service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram at one visual angle of the utility model noise reduction cover board；
Fig. 3 is the structural schematic diagram at another visual angle of the utility model noise reduction cover board；
Fig. 4 is the structural schematic diagram of the utility model embodiment 2.
In figure: motor stator 1 determines wind wheel 2, movable vane wheel 3, fan housing 4, noise reduction cover board 5, outside plate ring 51, mainboard body 52, noise reduction
Cylinder 53, main bloop 52a, secondary bloop 52b, rubber bar 6.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and detailed description.
Embodiment 1: in embodiment as shown in Figure 1 to Figure 3, a kind of low noise motor for dust catcher, including
Motor casing, rotor, determines wind wheel 2 and movable vane wheel 3 at motor stator 1；
The motor casing includes fan housing 4 and the noise reduction cover board 5 connecting with fan housing, upward in rotor axis of electric: noise reduction cover board
It is between fan housing and motor stator；
The noise reduction cover board includes outside plate ring 51, the mainboard body 52 being arranged in outside plate ring and the drop being arranged on outside plate ring
It makes an uproar cylinder 53, the mainboard body is equipped with multiple main bloop 52a, and motor stator passes through mainboard body, upward in rotor axis of electric: outer
Plate ring is between fan housing and noise reduction cylinder；
Noise reduction cylinder one end is fixed with outside plate ring, and noise reduction cylinder and rotor are coaxially arranged, and sound-absorbing is equipped in noise reduction cylinder
Cotton layer.
Motor itself can generate vibration, cause noise.There is main bloop on noise reduction cover board, the noise reduction of the first order can be played
Effect, then, noise reduction cylinder form a cylindrical space at noise reduction cover board back, to can avoid sound wave from noise reduction cover board back
It begins to outwardly be passed directly to or reflected, but second level noise reduction can be carried out in the space of a relative closure
(on the one hand one side noise reduction cylinder and acoustical cotton layer be passed through several secondary reflections by can be allowed sound wave more, be further functioned as noise reduction with sound-absorbing
Effect).
The mainboard body is equipped with multiple secondary bloop 52b, and main noise reduction number of perforations is greater than secondary noise reduction number, any main noise reduction
The spacing of hole and rotor axis is greater than the spacing of any secondary bloop and rotor axis.The presence of bloop can rise
Erasure effect to a certain extent, but due to motor of dust collector space and weight in terms of limitation, mainboard body can not be made
Thickness, at this point, noise reduction number of perforations should not simply more, otherwise will lead to the vibration aggravation of mainboard body.And opposite " outer " is set
The secondary bloop of main bloop and opposite " inner ", can effectively improve the rationally distributed property of noise reduction pore structure, both avoid whole disappear
Sound hole number is excessive and causes the vibration of mainboard body big, and avoids noise reduction number of perforations very few and cause erasure effect that cannot perform to
Good degree.(at the secondary bloop of opposite " inner ", close to vibroseis, i.e. motor itself, so vibration relatively easily becomes more
Greatly, relatively small number of secondary bloop is set, mainboard body integrality can be kept, reduce vibration)
Each main bloop is circumferentially uniformly distributed along rotor, and each pair bloop is circumferentially distributed along rotor.
Embodiment 2: the basic structure and embodiment of the present embodiment with embodiment 1, the difference is that, in Fig. 4
Shown, the motor stator includes stator skeleton and multiple stator punchings connecting with stator skeleton, and stator skeleton is equipped with more
A rubber bar 6, rubber bar one end are connect with noise reduction cylinder, and the rubber bar other end is connect with stator skeleton.
Each rubber bar is circumferentially uniformly distributed along rotor, circumferentially upper in rotor: adjacent rubber bar it
Between formed noise reduction gap.
What rubber bar played the role of first is support, can be shaken to avoid noise reduction cylinder excessive.Secondly, rubber
Bar itself has elasticity, can be buffered to noise reduction cylinder and motor stator, damping, to play the effect of noise reduction.Furthermore phase
Noise reduction gap is formed between adjacent rubber bar, so changed again when sound wave passes through noise reduction gap by aperture, from
And sound-deadening and noise-reducing can be further realized.So rubber bar plays the effect of three aspects simultaneously, can comprehensively carry out
Noise reduction damping.
