Air channel 3, reduces air current flow resistance, improves efficiency of dust collection.
As shown in Fig. 1-Fig. 7, when dust catcher such as vacuum, motor work forms negative pressure in air channel 3
(pressure is less than atmospheric pressure), outside air will be inhaled into air channel 3 along guide face 21 from nose air intake 41, while treating clear
Hair, dust and other impurities on reason surface 7 also follow air to be together drawn into air channel 3, reach cleaning effect.Wherein, by
In the setting of guide face 21, so during air is inhaled into floor brush of dust collector 100 along guide face 21, air will be along water conservancy diversion
The smooth flow of face 21, reduces air-flow and hits the vortex produced with surface 7 for clearance, eliminates the big whirlpool of separation caused by sharply changing section
Whirlpool, so that the energy loss of air-flow is reduced, and energy is conservation, flowed energy loss is low, then the energy for being converted to acoustic energy is low,
It is possible thereby to reduce aerodynamic noise.Meanwhile, guide face 21 can guide air-flow, make air current flow more steady, reduce air-flow
The tubulence energy and turbulence level of flowing, thus further reduce aerodynamic noise.
According to the floor brush of dust collector 100 of the utility model embodiment, by setting the diversion division 2 with guide face 21,
Outside air along guide face 21 be inhaled into floor brush of dust collector 100 when, can improve air-flow enter floor brush of dust collector 100 flowing shape

The vortex produced is hit in import, reduces the energy loss of air-flow, reduces aerodynamic noise.Guide face 212 is from front to back to updip afterwards
Tiltedly so that air-flow is during guide face after flowing through 212, and gas channel is flaring, according to Coanda effect (when fluid with
When there is mantle friction between the body surface that it flows through, as long as the curvature of body surface is less, fluid can be along body surface
Flowing, also known as attached wall effect), air-flow, which can be attached on rear guide face 212, to be flowed, and is eliminated because gas channel cross-sectional area is prominent
Separation vortex caused by becoming, reduces the turbulivity of air current flow, and then reduce aerodynamic noise.Further, since rear guide face 212 from
