With reference to Fig. 5 and Fig. 6, when to be cleaned surperficial D (for example wooden or varnished cloth floor) that needs cleanings can not be damaged by preceding stop member 40 and back stop member 50, select second cleaning mode.

If the user promotes the rear portion of pushbutton unit 21 so that suck brush and operate along the direction of F2 under second cleaning mode, then rotating shaft 23 direction that can be pushed along pushbutton unit 21 (just, rear portion towards brush body 10) the predetermined angle of rotation, simultaneously, the first pressure lappet 25 and the second pressure lappet 27 can pivot downwards.In this case, the first pressure lappet 25 and the second pressure lappet 27 can be to pressing down the first pressure slit 34a and the second pressure slit 34b, and portable plate 30 can be resisted the elastic force that is applied by the first helical spring 31a and the second helical spring 31b (with reference to Fig. 2) and descend along the first guide shaft 11e and the second guide shaft 11f (see figure 3).Subsequently, the first pressure lappet 25 can separate a part of 30a that also can always push down portable plate 30 upper surfaces from the first pressure slit 34a with the second pressure lappet 27 with the second pressure slit 34b, therefore preceding barrier structure 40 and back barrier structure 50 can be close to surperficial D.

If sucking brush moves forward at the second cleaning mode lower edge direction A, then because the friction between surperficial D and first stop arm 43 and the surperficial D and second stop arm 45, cause first stop arm 43 and second stop arm 45 to pivot around the rear portion of hinge axis 41 to brush body 10, therefore, as shown in Figure 5, first stop arm 43 can vertically contact with surperficial D basically, and second stop arm 45 can rise from surperficial D.In this case, first stop arm 43 can only suck air by described a plurality of air suction inlet 43a in suction inlet 13a, so the opening degree of suction inlet 13a can be restricted with respect to traditional suction brush.Therefore, can reduce the pressure loss between suction inlet 13a and the surperficial D and can keep suction.

In addition, in order to prevent to operate the difficulty that sucks brush, when first wheel 71 and second wheel, 72 contact surface D, use the high relatively suction that between suction inlet 13a and surperficial D, produces by first stop arm 43, the suction brush can be guided in surperficial D and go up level and smooth moving.

On the other hand, if sucking brush moves backward at the second cleaning mode lower edge direction B, then because the friction between surperficial D and first stop arm 43 and the surperficial D and second stop arm 45, cause first stop arm 43 and second stop arm 45 to pivot to brush body 10 front portions around hinge axis 41, therefore, as shown in Figure 6, second stop arm 45 can vertically contact with surperficial D basically, and first stop arm 43 can rise from surperficial D.In this case, second stop arm 45 and back barrier structure 50 can seal the periphery of suction inlet 13a so that suction remains on maximum horizontal.Second stop arm 45 can suck suction inlet 13a with the dust of air on surperficial D, and this can make the suction efficiency maximization.

As previously mentioned, when the suction brush is mobile backward, when first wheel 71 and second wheel, 72 contact surface D, use the high suction that between suction inlet 13a and surperficial D, produces by second stop arm 45, can also prevent to operate the difficulty that sucks brush.

Be clear that by aforementioned description, according to exemplary embodiment of the present disclosure, character according to surface to be cleaned, for example, its hardness, its material etc., sucking brush can operate under first cleaning mode or second cleaning mode, makes it possible to prevent that surface to be cleaned is damaged and makes the dust collection efficiency maximization.

In addition, when the suction brush moved forward under second cleaning mode, first of preceding barrier structure stopped that lappet can prevent that the suction of suction inlet periphery from reducing, and, simultaneously, first wheel and second wheel can make and suck brush level and smooth operability that sucks brush to improve that moves on surface to be cleaned.
