Description

Electric, dust collecting brush

The utility model relates to a kind of electronic, absorbent brush, and is with the brush etc. of the sanitation and hygiene in brush, the daily life, convenient, practical as blackboard in the teaching, and has dust-absorbing function.

In the prior art, the blackboard eraser that uses in teaching is manual felt scrubbing brush, when erasing the board the effort and make dust from flying, do not have dust-absorbing function.The cleaning brush kind of Shi Yonging is more in daily life, but does not have electronic, dust-absorbing function.

The purpose of this utility model provides a kind of electronic, absorbent brush, to solve above shortcomings in the prior art.

The utility model is achieved in that powered brush is made up of electronic control section in brush body, brush and the brush body.Electronic control section comprises motor, power supply, switch and step-down, rectification circuit.Brush body comprises shell and bonnet.Motor is fixed in the brush body shell by support, and brush is loaded on the output shaft of motor front end.Said structure promptly constitutes powered brush.On the basis of powered brush, fan blade is fixed on the output shaft of motor, and fan blade is positioned at the rear portion of brush.Establish filter at the shell of brush body and the junction of bonnet, the internal cavity of bonnet is done dust-storage chamber.Can constitute electric dust sucting brush.

Fig. 1 is the powered brush structural representation;

Fig. 2, Fig. 3, Fig. 4 are the enforcement illustration of electric dust sucting brush;

Fig. 5 is that the A of Fig. 1 is to view;

Fig. 6 is that the B of Fig. 2 is to view;

Fig. 7 is that the C of Fig. 2, Fig. 3 is to view;

Fig. 8 is control circuit figure of the present utility model.

Among the figure, 1 be shell, 2 is bonnet, 3 is motor, 4 is brush, 5 is support, 6 is fan blade, 7 is filter, 8 is battery case, 9 is dust-storage chamber, 10 is attaching plug, 11 is switch, 12 for hand over, straight, fill switch, 13 is soft tongue, 14 is handle.K1 is power switch (part 11), simultaneously switch 220V AC power and battery power.K2 is change-over switch (part 12), pushes " friendship " position K1 and connects 220 power supplys through step-down, the work of rectification drive motors; Push " directly " position, K1 connects the battery driven machine operation; Push " filling " position, K1 connects the 220V power supply through step-down, rectification, to batteries charging.

Among Fig. 1, the brush of powered brush 4 is fixed on the front end output shaft of motor 3 for garden shape brush, and brush body is made up of shell 1 and bonnet 2, and motor 3 is fixed in the shell 1 by support 5, and the rear portion of shell 1 is provided with battery case 8.

Among Fig. 2, brush 4 electronic, absorbent brush is blade shaped brush (same Fig. 2 of head shapes among Fig. 3, Fig. 4).Brush body is made up of shell 1, bonnet 2 and handle 14.Brush 4 and fan blade 6 are loaded on (motor is single shaft output) on motor 3 output shafts.Motor 3 is fixed in the shell 1 by support 5, on the support 5 through hole is arranged.Filter 7 is located at shell 1 and bonnet 2 connection places.Establish through hole on the bonnet 2, the cavity in the bonnet 2 is a dust-storage chamber 9.Battery case 8 is located on the handle, also has switch 11 on the handle, attaching plug 10 and hand over, straight, fill switch 12.

The difference of Fig. 3 and Fig. 2 is that motor 3 selects the output shafts motor for use, and brush 4 is loaded on the motor front end output shaft, and fan blade 6 is loaded on the output shaft of motor rear portion.

The internal structure that the internal structure of Fig. 4 adopts Fig. 2 or Fig. 3 all can, its difference is the shell of brush body and handle as one, filter 6 and bonnet 2 are located at the handle bottom, the place, air channel in handle is provided with soft tongue 13.
