Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be described in detail.
Fig. 4 is the plan structure schematic diagram of vacuum cleaner bottom in the present invention, Fig. 5 be in the present invention vacuum cleaner bottom look up structural representation, Fig. 6 is the side-looking structural representation of vacuum cleaner bottom in the present invention.
As shown in the figure, drain pan 1 front end of the horizontal dust collector with present configuration feature is provided with the adapter 2 being connected and connecting dust collect plant with hose, the anterior radial reinforcement 3 of drain pan 1 be centrally formed with caster frame aperture 4, be used for bound feet wheel carrier (not shown) is installed.
The both sides, rear portion of drain pan 1 have been correspondingly formed rear truckle pedestal 5 and castor baffle plate 6 respectively.
The perforation plate 11 at the rear portion of drain pan 1 disposes the motor box (not shown) of content dust sucting motor.The air inlet of motor box connects with the dust collect plant of drain pan 1 front portion, the gas outlet of motor box connects with the filtering grid of drain pan rear end, the side, rear portion of drain pan 1 is formed with winder power source line and draws, and the power line connecting attaching plug exports 8, the rear end of drain pan 1 is also formed with installing the slot 9 of filtering grid.
Noise reduction bottom board under a kind of motor of dust collector box of the present invention, mainly includes the motor box of dust collect plant and the content dust sucting motor disposed in drain pan 1, is the perforated plate deafener 10 constituting drain pan 1 below its motor box.
Noise reduction bottom board under described motor of dust collector box, its perforated plate deafener 10 is to be formed with how several bloop 12 on the perforation plate 11 of drain pan 1, and drain pan 1 bottom surface is provided with one and contains the reassembling type base plate bonnet 13 of how several bloop 12.
Noise reduction bottom board under described motor of dust collector box, on its perforation plate 11 formed how several bloop 12 is lattice arrangement.
Fig. 7 is the decomposition texture schematic diagram of drain pan and base plate bonnet in the present invention, and Fig. 8 is the perspective view of base plate bonnet in the present invention.
