So, in the present embodiment, do not reduce under the prerequisite of the original performance of suction pieces main body, for roll brush 11 is installed forward as far as possible, on the body shell of forming by upper shell 2, lower house 3, do not establish and the same in the past antetheca, replace and form antetheca by cushion pad 20 with sled shape.This cushion pad 20 is installed across both sides from the front, but front one side is provided with to the swept surface fin 21 that is formed by elastomer (soft polyvinyl chloride) vertically downward.In addition, make roll brush 11 be positioned at the rotary motion trace of its long brush body 9a and fin 21 position contacting of above-mentioned cushion pad 20.Thus, roll brush 11 1 rotates, and contacts vibration fin 21 with the fin 21 of cushion pad 20 with regard to brush body 9a.Also have, in the present embodiment, fin 21 and cushion pad 20 form one, form but also can make independent part by elastomer.

Have, the fin 21 of above-mentioned cushion pad 20 forms a plurality of thinner wall section 22 that horizontal ditch shape extends again, and thus, constituting increases elasticity and make its easy vibration.

Also have, be positioned at the pivot top of above-mentioned roll brush 11, be provided with, do not increase under the situation of roll brush 11 load, can prevent that the fin 21 of cushion pad 20 from swinging to the inboard from the support component 23 of fin 21 roots of medial support cushion pad 20.

In addition, the bottom surface of the suction pieces main body 1 of present embodiment, the lower position that is positioned at tube connector 5 is provided with and in the past the same trailing wheel 25, but the both sides, front of suction pieces main body 1 are because the spatial relationship of said structure, front-wheel is not set, and fleece (nylon loop) 26 is installed to replace.

In addition, above the upper shell 2 of suction pieces main body 1, be positioned at and swivelling pipe 4 corresponding positions, form the protruding top 27 of protruding.

In above structure, during the cleaning corner, shown in Figure 10,12, when floor-sucking part is pushed down, so that its cushion pad 20 is when contacting with wall, distance (size B) between the ground plane of distance of the front end of wall surface and roll brush 11 (size A) and wall surface and roll brush 11 becomes minimum, so improved cleaning corner performance.

In contrast, when using conventional art, as shown in figure 11, the front of roll brush 11 has sled shape part 30, front-wheel 31 etc. are set on the antetheca, and therefore, size A becomes 10～15mm; Can not contact swept surface at brush body (or impeller) 9 than (at interval) roll brush 11 of its big size B, and can not suck the rubbish such as the end of a thread that are entangled on the carpet device, but A and size B become minimum in the present embodiment, can comb the rubbish such as the end of a thread on the carpet of being entangled in of sucking-off wall angle.

And then this moment, fin 21 by cushion pad 20 contacts with long one the brush body 9a of roll brush 11, fin 21 vibration of cushion pad 20, it is the same just in time to play roll brush 11, can obtain to comb the special efficacy that is entangled in the rubbish such as the end of a thread on the carpet that sucts till the wall corner.

Also have, because the brush body 9a of the roll brush 11 that touches with cushion pad 20 fins 21 forms helical form, so often partly contact with the fin 21 of cushion pad 20, and the time with wavy vibration fin 21, the rotating speed that can prevent to be subjected to big load on the roll brush 11 disposablely and cause reduces, thereby when not reducing the performance of roll brush 11 itself, utilize the stable vibration of the fin 21 of cushion pad 20 to comb effectively to suct the rubbish on the carpet till the corner.

In addition, form thin (meat) sheet portion 22 of ditch shape that horizontal direction extends on the fin 21 of cushion pad 20, the vibration that can increase fin 21, on the comb of fin 21 on the carpet effect of rubbish become big, further improve the efficient of cleaning wall angle.

Also have, be positioned at above the pivot of roll brush 11, be provided with from the support component 23 of fin 21 roots of medial support cushion pad 20, thus, roll brush 11 mainly contacts with the fin 21 of rubber-like cushion pad 20, so reduce the load of roll brush 11.

Also have, when cleaning carpet usually, as shown in figure 13, because the attraction carpet sucts suction inlet 7, the front end of the fin 21 of cushion pad 20 contacts with carpet, the floor is pressed to forward with suction pieces wants the floor cleaned, then fin 21 will be swung to a side of roll brush 11, and the danger that increases roll brush 11 loads is arranged; But, in the present embodiment, utilize to support the root of above-mentioned support component 23 support fin 21 internally, can limit fin 21 and swing to the inboard, and further reduce the load of roll brush 11 from root.

In addition, in above-mentioned, roll brush 11 is then up combed the fin 21 of swinging to inboard cushion pad 20 from the bottom direction rotation of suction during with respect to direction of advance reverse rotation (Figure 13 clockwise direction rotation), and therefore, the resistance when contact with fin 21 becomes greatly; Even the roll brush 11 that the motor of present embodiment 12 drives, that is, power brush, electric current also becomes greatly because resistance becomes big, thus the load that the motor 12 of the waste electricity charge, roll brush 11 takes place becomes big and problems such as life-span reduction, temperature rising occur.In addition, if without the turbine brush of motor or utilize the extraneous air power that blade sucked in and the roll brush that rotates then can not obtain sufficient revolving force, reduce the performance of picking up rubbish.

To this, in the present embodiment, direction of advance with respect to floor-sucking part, roll brush 11 direction of rotation, direction is the same shown in the X arrow of Figure 13 positive direction is set, therefore and the contact resistance of the brush 11 of the powered rotation in the present embodiment and the fin 21 of cushion pad 20 diminish, can reduce the current value of the motor 12 of roll brush 11, thereby avoid waste the electricity charge; Also utilize the load that alleviates motor 12 can suppress to reduce life-span or temperature rising.In addition, if the roll brush that turbine brush or the extraneous air power of utilizing blade to be sucked in are rotated can only just change, and the rotation of roll brush becomes slyness, improve and pick up the rubbish performance.

Have, if there is the danger that rubbish is flown out forward in counter-rotating, but just changes, it is so undesired not have again.

Also have, cancellation sled shape antetheca as in the above-mentioned structure, it should be noted that the destruction or the distortion of roll brush 11.That is, the floor is turned over when placing with suction pieces in the cleaning way, when not noting stepping on, roll brush 11 is subjected to as shown in figure 14 power and destroyed or be out of shape the problem that appearance can not re-use temporarily.

As countermeasure, in the present embodiment, as shown in figure 15, a side forms protruding top 27 above the suction pieces main body 1, so that when the floor is turned over placement with suction pieces, one side of roll brush 11 step-down that fully tilts, simultaneously, the structure that the brush body 9a of roll brush 11 is more outstanding than the bottom surface of suction pieces main body 1 is in the time of will stepping on pin, pin is the outstanding brush body 9a of contact earlier, along the inclination of bottom surface, slide forward, roll brush 11 changes to the direction of arrow Y, so directly not stressed on the core body 10 of roll brush 11, can prevent to destroy, be out of shape.

And then, when utilizing resilient, that plastic deformation is little materials such as foaming ABS resin to form core body 10, the size C of the periphery of the core body 10 when the samely quilt being turned over as shown in figure 15 and the space face of the roll brush storage chamber 8 below it is limited within the strain of core body 10, thereby reliably prevents destroyed and distortion.

Also have, in the foregoing description, the situation that its front end is contacted with the fin 21 of cushion pad 20 has been described, but when just cleaning, contact that to swing to the degree of fin 21 of inboard by attraction approaching, also can obtain same action effect to the installation of roll brush 11.

As above-mentioned, invent according to this case, when the antetheca of suction pieces main body is formed by elastomer, roll brush is installed, it is contacted or approaching with above-mentioned elastomer, the vibration elastomer just in time plays a part equally with roll brush, can obtain to comb the distinctive effect of the rubbish such as the end of a thread that are entangled in carpet till the corner, sucking-off floor.Also, because the installation forward in the past of roll brush ratio improves the performance in cleaning wall corner.Above-mentioned elastomer can effectively utilize cushion pad.

And then above-mentioned cushion pad has towards the swept surface fin of being made by elastomer vertically downward, and roll brush contacts with its fin or be approaching.

In addition, the brush body of roll brush, blade etc. form helical form, a part often contacts with the fin of cushion pad, in the time of wavy vibration fin, roll brush is not subjected to momentary big load, prevents the reduction of rotary speed, therefore, by the stable vibration of the fin of cushion pad, effectively comb the rubbish on the carpet till the sucking-off corner.

In addition, by the fin of above-mentioned cushion pad being formed ditch shape thinner wall section, the vibration that can strengthen fin becomes big by the effect of the comb sucking-off rubbish of fin, further improves the efficient in cleaning wall corner.

In addition, be positioned at above the pivot of roll brush, by the support component of the fin root that supports cushion pad is set, roll brush mainly contacts with the fin of rubber-like cushion pad, so when reducing the load of roll brush, can limit the fin of cushion pad and swing to the inboard internally, further reduce the load of roll brush.

In addition, above-mentioned roll brush, its rotation direction is with respect to the fin of above-mentioned cushion pad, leading section installation rotatably from top to bottom, owing to attract to swinging to inboard fin, not upwards to comb from the bottom to inhale, and rotation from the top down, reduce contact resistance with fin, if power brush, can reduce the current value of its motor, the electricity charge of avoiding waste, by the load that alleviates motor, suppress to reduce life-span and temperature rising again.Also have, if turbine brush, it rotates slick and sly, improves and picks up the rubbish performance.
