It sets, there is air guide hole, mounting bracket 202 to be set at air inlet 12 at the center of umbrella air guide member 208, multiple first supporting racks 204
It is spaced apart between mounting bracket 202 and umbrella air guide member 208, multiple second supporting racks 206 are spaced apart in umbrella air guide member
Between 208 and umbrella sound insulating member 210, so as to air-flow through in the gap between multiple first supporting racks 204, multiple second supporting racks
By air guide hole after in gap between 206, into air inlet 12.
In this embodiment, by setting wind guiding component 20 to the umbrella air guide member 208 and umbrella that two are oppositely arranged
Sound insulating member 210, and it is respectively erected in air inlet 12 and umbrella by multiple first supporting racks 204 and multiple second supporting racks 206
Between air guide member 208 between umbrella air guide member 208 and umbrella sound insulating member 210 so that air-flow can pass through multiple first and support
Air inlet 12 is flowed in gap between part, and flows to air inlet 12, i.e. air-flow from the gap between multiple second support elements
It avoids straight line to flow to air inlet 12, but enters air inlet 12 from four circumferential center convergences, and led by umbrella air guide member 208
Stream improves the smoothness of air-flow entrance, reduces the vortex degree of air-flow, and then reduce the impact to air inlet 12, drops
Low air inlet noise, in addition, by the setting umbrella sound insulating member 210 at the outside of umbrella air guide member 208, opposite air guide hole, and should
The umbrella point position of sound insulating member is far from air inlet 12, after enabling to the air inlet noise backpropagation at air inlet 12, by umbrella every
Sound part 210 stops, is further reduced the noise of dust catcher transmission, improves user experience.Preferably, umbrella air guide member 208 and umbrella
Multiple through-holes are set on shape sound insulating member 210, and to increase air inflow, the diameter range of through-hole is 2mm to 4mm, and the quantity of through-hole is 5
It is a to 30.
In one embodiment of the utility model, it is preferable that as shown in Figure 13 and Figure 14, dust catcher further includes：First
Elastic component 22 and the second elastic component 24, are located at the both ends of getter device 18, and getter device 18 passes through 22 He of the first elastic component
Second elastic component 24 rides upon inside casing 10；Wherein, the first elastic component 22 has first through hole 222, the second elastic component 24 tool
There is the second through-hole 242, multiple support protrusions being spaced apart are equipped on the hole wall of first through hole 222 and the second through-hole 242
26, support protrusion 26 fits with getter device 18.
In this embodiment, getter device 18 is wrapped up by using multiple support protrusions 26, and between multiple support protrusions 26
Every be arranged on the hole wall of first through hole 222 and the second through-hole 242 so that during getter device 18 vibrates, support
Protrusion 26 can be pressurized first into the space of ambient separation elastic dilatation so that 26 flat deformation of support protrusion reduces support
Protrusion 26 reduces the deformation quantity of first through hole 222 and the second through-hole 242, and then reduce biography in the deformation quantity of protrusion direction
It is handed to the amount of elastic deformation at 24 edge of 22 edge of the first elastic component and the second elastic component, getter device 18 is effectively reduced and is transferred to
Oscillation Amplitude on casing 10 reduces the noise of dust catcher, improves the use feel of user.In addition, passing through the branch being spaced apart
Support protrusion 26 fits with getter device 18, reduces the usage amount of elastic material, thereby reduces the production cost of dust catcher.
In one embodiment of the utility model, it is preferable that as shown in figure 15, dust catcher further includes：Motor cover, motor
The enclosure is located on motor 182, and motor cover includes：Shell 28, shell 28 are hollow structure, and one end of shell 28 is opening, shell
Venthole 282 is offered on 28 wall surface；Water conservancy diversion cavity 30 is arranged on the internal face of shell 28, water conservancy diversion cavity 30 and outlet
Hole 282 is connected, and air admission hole 302 is provided on water conservancy diversion cavity 30；Wherein, air-flow is through 28 one end of shell after motor 182 starts
Opening enters in shell 28, enters in water conservancy diversion cavity 30 using air admission hole 302, is flowed out by venthole 282.
In this embodiment, by the way that hollow water conservancy diversion cavity 30 is arranged on the internal face of shell 28 so that air-flow is flowing
Air admission hole 302 is first passed through after entering in shell 28 to enter in water conservancy diversion cavity 30, is flowed out later using venthole 282, in this way
Structure and water conservancy diversion for gas so that the flow direction of gas forms the path of a bending, so that air-flow is outside
The noise of transparent transmission becomes smaller, while the noise that can be also generated to air-flow of hollow water conservancy diversion cavity 30 form and certain gather work
With reducing the noise that spreads out of outward, thus reduce motor 182 and dust catcher noise at work and vibration, promote user's
Usage experience, while the motor shield structure is simple, convenient for manufacture, also can effectively reduce the production cost of product.
