Filter 600, air cleaner 600 is used to filter the gas to be discharged.
The motor cover body 100 of dust catcher 1000 according to embodiments of the present invention is described with reference first to Fig. 1-Fig. 7.
As shown in Fig. 1-Fig. 7, the motor cover body 100 of dust catcher according to an embodiment of the invention 1000 includes outer cover
110 and inner cover 120.
Wherein, outer cover 110 is connected with the housing 200 of dust catcher 1000, and the bottom wall of outer cover 110 can be with the bottom of housing 200
Seat 210 is spaced apart, and outer cover 110 can be lifted in the housing 200 of dust catcher 1000, and inner cover 120 is lifted on outer cover 110 at least
Under part, such as outer cover 110 can be connected through a screw thread part and be connected with inner cover 120, and between the bottom wall and outer cover 110 of inner cover 120
Separate, the electric machine assembly 300 of dust catcher 1000 is suitable to be supported on inner cover 120 and is kept apart with the bottom wall with outer cover 110, and motor
Component 300 is located in the accommodating chamber 101 that outer cover 110 is limited jointly with inner cover 120, and inner cover 120 and outer cover 110 also define sky
Flow channel is derived for the air-flow that electric machine assembly 300 is sucked.
It is understood that electric machine assembly 300 includes motor 310 and motor wedge 320, motor 310 is supported on motor pressure
On seat 320, motor wedge 320 is supported on inner cover 120, and such motor wedge 320 is successively coated by inner cover 120 and outer cover 110,
So as to be separated by multiple cover body and air and the base 210 of housing 200 between, the vibration of motor 310 just can only be by motor
Wedge 320 passes to inner cover 120, and rather than being passed directly to base 210, and the mode of lifting connection can absorb a part of vibration,
The multiple isolation that vibrating noise passes through inner cover 120, outer cover 110 and air, the vibrating noise of motor 310 is greatly decayed.

In in accommodating chamber 101, inner cover 120 and outer cover 110 also define air flow channel so that the air-flow that electric machine assembly 300 is sucked is led
Go out.
It is understood that electric machine assembly 300 includes motor 310 and motor wedge 320, motor 310 is supported on motor pressure
On seat 320, motor wedge 320 is supported on inner cover 120, and such motor wedge 320 is successively coated by inner cover 120 and outer cover 110,
So as to be separated by multiple cover body and air and the base 210 of housing 200 between, and due to the buffer action of outer cover cover plate 113,
Air-flow cannot be passed directly to the base 210 of housing 200, and the gap between outer cover cover plate 113 and base 210 can further rise
To the effect of isolation pneumatic noise, further, the mode that inner cover 120 is connected with the lifting of outer cover 110 can absorb a part and shake
Move, the multiple isolation that vibrating noise passes through inner cover 120, outer cover 110 and air, the vibrating noise of pneumatic noise and motor 310 can
Greatly to be decayed.
The motor cover body 100 of dust catcher 1000 according to embodiments of the present invention, is vibrated by multiple cover body to motor 310
Isolation, and isolation of the outer cover cover plate 113 to air-flow, can prevent vibrating noise and pneumatic noise to be directly delivered to dust catcher
1000 housing 200, helps to weaken the operating noise of dust catcher 1000.
As shown in Fig. 1-Fig. 7, the motor cover body 100 of the dust catcher 1000 according to another embodiment of the invention includes：Before
Lid 114, outer cover 110 and inner cover 120 on air guide structure 500, outer cover.
Wherein, preceding air guide structure 500 is suitable to be located at the suction inlet top of the electric machine assembly 300 of dust catcher 1000, on outer cover
Lid 114 is connected with preceding air guide structure 500, to limit preceding wind guide chamber 105, in other words, is covered on preceding air guide structure 500 and outer cover
114 limit preceding wind guide chamber 105 jointly, and preceding air guide structure 500 can be connected in dirt cup between lid and electric machine assembly 300, dirt
Cup 400 is located at the side of preceding air guide structure 500 and electric machine assembly 300, and preceding air guide structure 500 may be located at electric machine assembly 300
Top, such that it is able to guide the gas flowed into from whole machine air inlet 1001 from the flow direction motor component 300 of dirt cup 400.
The upper end of outer cover 110 is connected with lid on outer cover 114, on outer cover lid 114 can with the upper end of closed cover 110 so that
Air flow channel is formed in outer cover 110, can be connected with clamping between lid 114 and outer cover 110 on outer cover.
Inner cover 120 be lifted on outer cover 110 it is at least part of under, in the electric machine assembly 300 of dust catcher 1000 is suitable to be supported on
On cover 120, and the accommodating chamber 101 that outer cover 110 and inner cover 120 are limited jointly, electric machine assembly 300 is suitable to be located at accommodating chamber 101
Interior, inner cover 120 and outer cover 110 also define air flow channel so that the air-flow that electric machine assembly 300 is sucked is derived.
Inner cover 120, outer cover 110 and lid 114 limits air flow channel on outer cover, accommodating chamber 101 by air flow channel with inhale
The whole machine exhaust outlet 1002 of dirt device 1000 is connected, it is preferable that inner cover 120, interior cover plate 123, outer cover cover plate 113, the and of outer cover 110
Lid 114 limits air flow channel jointly on outer cover, and the concrete shape and generation type of air flow channel will be made further below
Describe in detail.
It is understood that electric machine assembly 300 includes motor 310 and motor wedge 320, motor 310 is supported on motor pressure
On seat 320, motor wedge 320 is supported on inner cover 120, and such motor wedge 320 is successively coated by inner cover 120 and outer cover 110,
So as to be separated by multiple cover body and air and the base 210 of housing 200 between, inner cover 120 lifts the side being connected with outer cover 110
Formula can absorb a part of vibration, the multiple isolation that vibrating noise passes through inner cover 120, outer cover 110 and air, pneumatic noise and electricity
The vibrating noise of machine 310 can greatly be decayed, and the air of the suction of 310 the past of motor wind guide chamber 105 enters accommodating chamber
101, then discharged from whole machine exhaust outlet 1002 by air flow channel.
As shown in Figure 5-Figure 7, at least part of inner surface of at least one of preceding wind guide chamber 105 and air flow channel can set
There is a reflection groove 106, reflection groove 106 can reflect noise, lid 114 at least part of inner surface of preceding air guide structure 500, outer cover
In at least part of inner surface, at least part of inner surface of outer cover cover plate 113, at least part of inner surface of interior cover plate 123 extremely
Few one is provided with reflection groove 106.
Such as, if preceding air guide structure 500 is provided with reflection groove 106, the inner surface towards suction inlet of preceding air guide structure 500
It is provided with reflection groove 106.The reflection groove 106 set on miscellaneous part will be further described in examples below.
Air-flow flows in preceding wind guide chamber 105, and the air flow channel that air-flow is formed from inner cover 120 with outer cover 110 passes through,
Noise is also propagated in the channel, and when the inwall of sound transmission to air flow channel, sound can reflect, as shown in fig. 7, by setting
Reflection groove 106, can make the reflection direction of sound becomes mixed and disorderly unordered, part reflection sound wave with original acoustic phase conversely,
Can just offset, reach the purpose of sound-deadening and noise-reducing.
The motor cover body 100 of dust catcher 1000 according to embodiments of the present invention, is vibrated by multiple cover body to motor 310
Isolation, can prevent vibrating noise and pneumatic noise to be directly delivered to the housing 200 of dust catcher 1000, by setting reflection groove
