In the whole oblique view of Fig. 3,1 is cleaner head of the present utility model, and this cleaner head 1 is connected with electric dust collector 2 by extension pipe 4, flexible pipe 3.The inside of flexible pipe 3 and extension pipe 4 is hollow form, and the electric fan 5 that is arranged on electric dust collector 2 rear sides attracts the air of its inside and with its discharge, makes inside become vacuum state, is applied with negative pressure, attracts air-flow thereby produce.
As shown in Fig. 1 and Fig. 2, on rear portion on cleaner head 1 fore-and-aft direction and the position that mediates substantially, the conduit 6 that can rotate freely is being set on direction all around.The inside of conduit 6 is hollow form, and the one end is connected on the electric dust collector 5 through extension pipe 4 and flexible pipe 3, and the other end is connected with the inside of cleaner head 1.Wherein, the opening that is connected with cleaner head 1 inside in the conduit 6 is for attracting mouth 7.
On the other hand, the structure of cleaner head 1 is: have the suction inlet 8 of opening downwards on the bottom surface, suction inlet 8 is connected with attracting mouth 7, and cleaner head 1 inner formed spatial portion constitutes suction chamber 9.Be provided with the rotating brush 10 that can rotate freely in the suction chamber 9, rotating brush 10 is adjacent with suction inlet 8, and is supported in apart from the distance of suction chamber 9 inner front and approximates on the rotating shaft (not shown) of its radius of turn.Rotating brush 10 is by the left and right either side that is arranged on conduit 6 or be arranged to coaxial drive source 11 with conduit 6 power is provided, and can rotate.Generally speaking, drive source 11 is arranged on the left and right sides either side of conduit 6, has set up belt 12 between rotating brush 10 and the drive source 11.In addition, drive source 11 general motor or the turbine mechanisms etc. of using.
The inside top surface of cleaner head 1 and be arranged on that formed space is air channel 13 between the dividing plate on suction chamber 9 tops.Because suction chamber 9 is roughly cylindrical shape, air channel 13 is also along cylindric formation, and the vertical cross-section shape in air channel 13 is narrowing down on the direction of the front portion of cleaner head 1 gradually.Air channel 13 is provided with a plurality of openings in the front portion of suction chamber 9, constitutes peristome 14 (referring to Fig. 2), thereby air channel 13 is connected with suction chamber 9.Peristome 14 is positioned at the place ahead of the pivot of rotating brush 10, and in the antetheca of suction chamber 9 side opening.Preferred plan is, peristome 14 is provided with 3 places or more openings on the length direction of cleaner head 1, and particular location is the centre and the left and right sides on the length direction of cleaner head 1.
As shown in Figure 2, a plurality of peristomes 14 form air channel 13 respectively, and each air channel 13 pools together at the rear portion of cleaner head 1.In other words, air channel 13 is set up at the rear portion and concentrates on a place earlier, shunts to each peristome 14 then.
On cleaner head 1 end face at the Rendezvous Point place in air channel 13, be formed with opening 15.This opening 15 is arranged near the opening of air channel 13 Rendezvous Points, and communicates with air channel 13.Like this, air channel 13 forms a gas channel by opening 15 and peristome 14, also is provided with on the opening 15 to be used to close/the adjustment valve 16 of open operation.In general, control valve 16 is installed on the rotary axle, closes by rotating, open operation.The concrete structure of control valve 16 can adopt: the air pressure in air channel 13 during greater than atmospheric pressure valve from below the effect by added power such as springs under close and the valve self that can open when in air channel 13, adding negative pressure state can knee-action structure; Or under the active force of leaf spring, can finish the structure (it is not shown that elastic force applies structure) of same operation.
Operational circumstances and effect to cleaner head with said structure is described below.When using electric dust collector 2 to carry out dust suction, electric fan 5 work with the air suction in electric fan 5 the place aheads, are rearward discharged again, make it become vacuum state, are applied with negative pressure, attract air-flow thereby produce.Particularly, such negative pressure is passed on the cleaner head 1 by flexible pipe 3, extension pipe 4, and the negative pressure that is produced produces in cleaner head 1 and attracts air-flow, and the dust on the swept surface is attracted.
Negative pressure at first by conduit 6, again by attract mouthfuls 7 and suction chamber 9 be passed in the suction inlet 8.Dust mainly is inhaled into mouth 8 and collects.
At drive source 11 is under the situation of motor, and motor can obtain power supply from electric dust collector 2, and rotating brush 10 is rotated driving.On the other hand, be under the situation of turbine mechanism at drive source 11, turbine mechanism will be driven by the attraction air-flow that negative pressure produced, and its power also is delivered on the rotating brush 10, and rotating brush 10 is rotated.Not only the dust on the swept surface has been swept, collected during rotating brush 10 rotations, but also swept surface has been carried out sanding operation by mechanical force.The dust of having been swept by rotating brush 10 is inhaled in the dust collector host body through suction chamber 9.
Meanwhile, above-mentioned negative pressure also is delivered in the air channel 13 by peristome 14.When running into corner such as corner when cleaner head 1, negative pressure increases suddenly, adjust valve 16 in air channel 13 high negative pressure and the effect of the air that flows to from the outside under be pressed, opening 15 is opened, peristome 14 is communicated with extraneous air, produce outer conductance and go into air-flow.Outer conductance is gone into air communication and is crossed peristome 14 and flow into dust suction chambers 9 inside, and the negative pressure in the suction chamber is reduced, and prevents from that suction nozzle from inhaling extremely to locate in the corner.Simultaneously, go into the front side that air-flow blows to rotating brush 10 by making outer conductance, the air-flow of extraneous air will become the air-flow that transports that dust is guided to suction chamber 9 one sides, can prevent to be set to mechanical force that the rotating brush 10 of end face produces so always the dust in anterior corner is dispelled laterally, thereby can carry out control of dust effectively.Particularly, the open amount of the adjustment valve of opening 16 if strengthen under the negative pressure pressure when cleaner head 1 touches the corner, uprising, can improve the extraneous air air quantity, strengthen the conveyance air-flow, need not to worry again that the mechanical force of rotating brush 10 dispels the dust in the corner, the place ahead, thereby the dust in the place ahead can be captured expeditiously.
In addition, by adjust the open amount of control valve 16 by the negative pressure pressure of suction chamber 9 inside, the peristome 14 that can regulate 13 front portions from the air channel is directed into the extraneous air air quantity in the suction chamber 9, the open amount of the adjustment valve of opening owing to the negative pressure pressure effect that raises when increase cleaner head 1 touches the corner 16, improve the extraneous air air quantity, the negative pressure pressure of suction chamber 9 inside is descended.Afterwards, leave moment in corner in cleaner head 1, control valve 16 is towards the closing direction motion, and negative pressure will uprise quickly, and dust will be captured forcefully under the attraction air-flow effect of its generation; Add the mechanical force of rotating brush 10, the dust in cleaner head 1 the place ahead can be captured forcefully.
In sum, dust absorption head for electric vacuum cleaner in the utility model and use the electric dust collector of this cleaner head can be effectively, have no to capture in the room etc. dust with omitting until corner, very easy to use, always can make us happy dust suction operation.The utility model can be used in family expenses, business widely and use etc. in the various electric dust collectors.
