The specific embodiment

Fig. 1 is the stereogram of vacuum cleaner nozzle 1.Suction nozzle 1 comprises, allows suction nozzle to be connected to the tube connector 3 of vacuum cleaner.Suction nozzle further comprises, the shell 5 of the direction of motion horizontal expansion that the relative suction nozzle of being represented by the arrow among Fig. 17 is generally expected that.The base of shell defines cleaning face or planing surface, faces the ground that is cleaned.In illustrative example, the cleaning face is rectangle substantially, demonstrates long forward and backward limit and short left and right limit.The back is meaning, and when being connected to tube connector 3, vacuum cleaner is to that limit of the direction of vacuum source extension.

Suction nozzle has the pedal 9 that can be handled control by the user between first and second positions.In primary importance, delegation or multirow brush from the cleaning of suction nozzle towards will clean Surface stretching out.These brushes are used for keeping minimum range between the bottom surface of suction nozzle shell and ground, swiped for fear of ground, and, power appropriateness, uniform that the space between suction nozzle cleaning face and ground applies.In addition, the hair of brush is used for impelling dust particle to enter air-flow under the suction nozzle in efficient mode.Yet when cleaning carpet, these brushes are of no use.On the contrary, it is very big that the friction between suction nozzle and the carpet may become, and so, may be difficult to efficient mode mobile suction nozzle on carpet.Therefore, the user can handle control pedal and enter the second place, brush withdrawal thus, and so, they do not participate in cleaning course to a greater degree, and do not hinder suction nozzle moving on carpet.

Thereby in this example, the switch of operation brush is a pedal.By pedal, in this context, mean pin or hand by the user, between first and second positions, can be handled any mechanism or mechanism's set of control by the user.For example, except the pedal among Fig. 19, can consider lever or two buttons.

In addition, the suction nozzle among Fig. 1 has wheel 11, will clean Surface move in order further to help suction nozzle.

Downwards or at the vertically extending brush of extended position, be called as main brush hereinafter.As mentioning at first, suction nozzle of the present disclosure comprises one or more secondary brushes, and it stretches out to the surface that will be cleaned in the mode that tilts, and extend to outside the border of cleaning face at extended position, and so, secondary brush can be seen above suction nozzle.Because this feature, the user can Direct Recognition go out brush at extended position, not be used in and sees under the suction nozzle or see nearby at pedal.Example with reference to the accompanying drawings discusses the function of this feature now in more detail.

Fig. 2 A, 2B, 2C and 4 illustrate the vacuum cleaner nozzle (second place) of the brush that has withdrawal.Fig. 2 A illustrates the plane of the suction nozzle that exposes the cleaning face.Fig. 2 B illustrates the A-A cross section and Fig. 2 C that pass suction nozzle among Fig. 2 A the B-B cross section that passes suction nozzle among Fig. 2 A is shown.Fig. 4 illustrates the stereogram of the mechanism of exposure, just removes casing cover.Fig. 3 A, 3B, 3C and 5 illustrate the corresponding views (primary importance) of the vacuum cleaner nozzle that has the brush that stretches out.Fig. 6 illustrates the pedal of vacuum cleaner nozzle.

Begin with Fig. 2 A, the cleaning face 13 of suction nozzle is shown.Gas port 15 in the middle of the cleaning face is connected to tube connector 3 (Fig. 1), and transmits the air-flow of the dust particle that absorbs cleaning face 13 belows.At the forward and backward edge of cleaning face 13, the one 17 and the 2 19 main brush is set.The the one 21 and the 2 23 secondary brush is separately positioned on the right side, left rear corner (as the right and left side of the position at the frequent place of user when using suction nozzle) of cleaning face.As seeing, the first secondary brush 21 extends around the corner between cleaning face edge, back and the right cleaning face edge.The second secondary brush extends around the corner between cleaning face edge, back and the left cleaning face edge.

With reference to figure 6, rely on and prolong the trunnion of wearing first hole 27 in the pedal, pedal is set is connected to shell.Therefore, pedal can rotate around the pivotal line that conforms to first hole.Second hole 29 is set holds a hoop, and relative first hole is in vertical direction (vertical as what see from ground) biasing.

The pedal 9 of operation suction nozzle on hoop 25, these are optimal visibility in Figure 4 and 5.When user's operating pedal 9, hoop is displaced sideways shown in arrow among Fig. 5 31.Hoop 25 is U-shapeds, has long stage casing and two short latter ends.Pedal 9 keeps a latter end, and another latter end is by 33 clampings of hoop anchor clamps, and hoop anchor clamps 33 are pivotally connected to shell, and as pedal 9, so, two latter ends of hoop 25 will be finished in fact same motion.

By the roller bearing 37 that is connected the hoop latter end, hoop 25 is abideed by 35 actions of brush clamp tool successively.Brush clamp tool 35 comprises that the one 39 and the 2 41 is domatic, is arranged on by pedal to cause between the terminal position of hoop latter end of its motion.

Therefore, as optimal visibility in Fig. 2 C and 3C, when pedal 9 is transformed into extended position (primary importance from retracted position (second place is suitable for the carpet cleaning), be suitable for hard floor surface cleaner) time, pedal impels the position of hoop 25 to the right side of being looked, shown in Fig. 3 C in Fig. 2 C.Therefore, roller bearing 37 is raised on domatic 39,41, so, impels brush clamp tool 35 downward.Brush clamp tool 35 loading springs, so, when the user impelled pedal 9 to get back to original position, roller bearing 37 moved following time on domatic 39,41, impelled the brush clamp tool upwards to move back.As shown, the brush clamp tool can have recess at the terminal position of roller bearing, so, possesses snap action.

Therefore, pedal 9 is transformed into another from a position, can makes

main brush

17,19 move and move down expediently by the user.

With reference to figure 7 and 8, the motion of

secondary brush

21,23 is described now in more detail, the pair that Fig. 7 and 8 illustrates respectively among Fig. 2 B and the 3C is brushed the amplification cross section of 21 zones (contrasting Fig. 2 A).

At first, with reference to figure 7, secondary brush 21 locates to be connected to the brush clamp tool at link position 43 (shown in the example line shown in the cross section).The bearing 45 that is connected to the suction nozzle shell further is provided.When reducing, secondary brush is close to this bearing.Direction at the most approaching cleaning face edge, bearing 45 is from link position deviation distance d.When the brush clamp tool reduced, when the conversion pedal, secondary brush 21 interacted with bearing 45, and so, in image, pair is brushed warpage to the right, and the zone between bearing and link position is crooked.

Therefore, the free end of secondary brush outwards moves, and as visual in Fig. 8, extends to outside the cleaning face of shell.As visual in Fig. 3 A, pair is brushed 21 free end even is further extended to the zone that is lower than cross section shown in Fig. 7 and 8 slightly.Because the pair of extending brush, the user can investigate brush simply and stretch out, and stretches out as sightless main brush.

The invention is not restricted to described embodiment, and can change in a different manner within the scope of the appended claims and change.For example, can use many other mechanisms but not hoop described above-brush clamp tool, for example, have the secondary wheel of brushing bar along its periphery, by rotating this wheel, feasible brush bar stretches out or withdraws.As further change, can move each brush by the electrification transmission device.

In addition, can place secondary brush in any position of cleaning face periphery, edge, not only at the corner shown in Fig. 2 A.

Pedal in the illustrated embodiment can be changed into for example electric switch on another part of vacuum cleaner.Even can provide the full-automatic switch function, the existence of the carpet under its perception cleaning face or do not exist and correspondingly withdraw or stretch out brush.Can control such function by the pressure under the cleaning face.In that case, the user simply controls brush from carpet to level and smooth ground by mobile suction nozzle.Yet secondary brush still provides feedback information to the user, and so, the user can investigate suction nozzle and correctly move.
