As shown in fig. 6, according to second object of the present invention, the invention provides a kind of dust catcher, with first aspect
The guiding subassembly that any embodiment is provided, therefore, the dust catcher that embodiments of the invention are provided have any implementation of first aspect
The whole beneficial effects for the guiding subassembly that example is provided, it is numerous to list herein.
As shown in Figure 7 and Figure 8, in one embodiment of the invention, it is preferable that dust catcher also includes：First elastic component
42 and first elastic component 44, respectively positioned at the two ends of getter device 4, getter device 4 passes through the first elastic component 42 and the first elasticity
Part 44 is ridden upon inside jacket 2；Wherein, the first elastic component 42 has first through hole 422, and the first elastic component 44 has first to lead to
Hole 442, is equipped with multiple support protrusions 46 being spaced apart on the hole wall of first through hole 422 and first through hole 442, supports convex
46 are played to fit with getter device 4.
In this embodiment, getter device 4 is wrapped up by using multiple support protrusions 46, and multiple support protrusions 46 are spaced
Be arranged on the hole wall of first through hole 422 and first through hole 442 so that getter device 4 vibrate during, support protrusion
46 can be pressurized first into the space of ambient separation elastic dilatation so that the flat deformation of support protrusion 46, reduce support protrusion
46 protrusion direction deformation quantity, reduce the deformation quantity of first through hole 422 and first through hole 442, and then reduce and be transferred to
The amount of elastic deformation at the edge of the first elastic component 42 and the edge of the first elastic component 44, effectively reduces getter device 4 and is transferred to shell
Oscillation Amplitude on cover 2, reduces the noise of dust catcher, improves the use feel of user.In addition, convex by the support being spaced apart
Play 46 to fit with getter device 4, reduce the usage amount of elastomeric material, and then reduce the production cost of dust catcher.
In one embodiment of the invention, it is preferable that as shown in figure 9, dust catcher also includes：Motor cover 48, motor cover
48 are set on the motor inside getter device 4, and motor cover 48 includes：Housing 482, housing 482 is hollow structure, housing 482
One end be opening, offer venthole 484 on the wall of housing 482；Water conservancy diversion cavity 486, is arranged on the internal face of housing 482
On, water conservancy diversion cavity 486 is connected with venthole 484, and air admission hole 488 is provided with water conservancy diversion cavity 486；Wherein, after electric motor starting
Opening of the air-flow through the one end of housing 482 enters in housing 482, then enters by air admission hole 488 in water conservancy diversion cavity 486, by going out
Stomata 484 flows out.
In this embodiment, by setting hollow water conservancy diversion cavity 486 on the internal face of housing 482 so that air-flow exists
Air admission hole 488 is first passed through after flowing into housing 482 to enter in water conservancy diversion cavity 486, is flowed out, is passed through by venthole 484 again afterwards
Such structure and the water conservancy diversion for gas so that the flow direction of gas forms the path of a bending, and then causes air-flow
The noise of outside transparent transmission diminishes, while can also being formed to the noise that air-flow is produced for hollow water conservancy diversion cavity 486 is certain poly-
Hold together effect, reduce the noise that outwards spreads out of, thus reduce motor and dust catcher noise operationally and vibration, lifting user's
Usage experience, while the motor shield structure is simple, is easy to manufacture, also can effectively reduce the production cost of product.
