Adopt this structure, as shown in Figure 14 (b), be placed in the upright income of handle 300 so that with it under the posture on the suction nozzle 550, pin the locking mechanism 1553 of second rotating shaft 1535 and the locking mechanism 1516 of first rotating shaft 1553, so that can maintain upright income posture.In addition, when pinning the locking mechanism 1553 of second rotating shaft 1535, action roller 1564 stretches out and suction nozzle 550 falls forward, thereby it can and be contained in the balanced of the top hose 200 of handle 300, can keep stable posture thus.

Even under the situation that suction nozzle 550 moves along horizontal direction V1, also pin second rotating shaft 1535, can between this moving period, be easy to maintain the angle of handle 300 twisting action P1.Can also be locking mechanism 1553 be locked on the angle of high frequency of utilization with identical method that locking mechanism 1516 to second rotating shaft 1553 adopts.

In the Another Application example, can be higher than in the angle of the brush side tube connector 1531 on the height direction Y and pin locking mechanism 1553 under 90 ° the situation.In this case, a fin (not shown) is set with projection 1554 before matching, gives a resistance sense in the previous stage of locking at concave surface 1038.Therefore, when the angle initialization of handle 300 twisting action P1 is 90 °, the anglec of rotation P2 of suction nozzle 550 is set at 90 ° and when horizontal direction V1 moves suction nozzle 550, can not pin locking mechanism 1553.

On the other hand, if by twisting action angle P1 is set greater than 90 ° or height direction Y go up brush side tube connector 1531 angle initialization must greater than 90 ° surpassing operating vaccum suction cleaners under the situation of aforementioned resistance sense, then pin locking mechanism 1553.By doing like this, when when horizontal direction V1 moves suction nozzle 550, second rotating shaft 1535 does not pin and is in upright income attitude, can keep more stable posture.In addition, under the income attitude, needn't consider the action of suction nozzle 550, thereby can firmly set up lock-out state, thereby can obtain a more stable posture along horizontal direction V1.In this case, for opening locking mechanism 1553, preferably slam suction nozzle 550.

Below, with reference to the method for operating of vacuum cleaner 1 in Fig. 1 that expresses user mode figure and the 15 explanation present embodiments.

In Fig. 1, in the vacuum cleaner 1 at first in the present embodiment, when the user held the handle 300 of orthostatism, he can be by extension 400 by operation suction nozzle 550 cleaning floors.In the present embodiment, the length setting of extension 400 is got to make the extension 400 and the angle on ground be 450.The handle 301 of handle 300 is set in about 110 °, and to be easy to angle at extension 400 be mobile along the longitudinal direction extension 400 under 45 ° the state so that holding the user of handle 301.

Because the brush side tube connector 1531 of pipe joint 1530 is along height direction Y rotation, so also can not make the bottom and the ground of the suction nozzle 550 that suction inlet 1010 is housed isolated even suction nozzle 550 moves along the longitudinal direction.In this case, because extension 400 is tilted 45 °, so the rotating shaft of horizontal direction X upper outlet tube connector 1532 tilts 45 °, so that outlet connecting pipe 1532 is difficult for rotating along horizontal direction X because of the frictional force of rotating shaft, even mobile along the longitudinal direction suction nozzle 550 also can reduce the swing that horizontal direction X goes up suction nozzle 550.In addition, in the present embodiment, on second rotating shaft 1533, locking mechanism 1516 is set, so that can make the straight ahead motion of suction nozzle 550 become more satisfactory.

In addition, when suction nozzle 550 is mobile along the longitudinal direction, support suction nozzles 550 with front wheel 1261, rear roller 1262 and the support rollers in the middle of the roller bottom being loaded on 1,200 1263, these rollers rotate around rotating shaft 1211 as normal roller, thereby can strengthen the straight ahead motion.Especially in the present embodiment, with supporting roller 1263 to reduce the waving of end of the suction nozzle 550 that longitudinal direction moves, can obtain a gratifying forward travel.In addition, in the present embodiment, brush 1214 and rotating brush 1011 these two brushes with guiding device 1300 double to have collected ground dust, can increase pick-up performance.

In the present embodiment, by brushing side tube connector 1531 along just the rotation of direction Y and the straight ahead that outlet connecting pipe 1532 has been strengthened under 45 ° of states of normal posture extension 400 inclinations along the rotation of horizontal direction X are moved.But, can brush side tube connector 1531 along the rotation of horizontal direction X and the rotation of outlet connecting pipe 1532 edge height direction Y.In this opposite configuration, can with after the identical mode that previous embodiment is adopted is carried out with the rotary manipulation of the suction nozzle 550 of description.But, produced a problem by the straight ahead motion, consequently must be provided with and be used for preventing that horizontal direction X from going up the locking mechanism 1516 of rotation.

In the present embodiment, the action P1 of the handle 301 by reversing handle 300 can change the direction (rotation P2) of suction nozzle 550 with the rotation of handle 300.For example, be in line relative with suction nozzle 550 and be suitable under the straight-line situation, when handle 301 is reversed 45 °, also can tilt the direction of suction nozzle 550 45 ° by the effect of pipe joint 1530 at the handle of representing by solid line shown in Fig. 1 301.In this case, because the roller 1200 slip slideways of suction nozzle 550, so can be with the mobile along the longitudinal direction suction nozzle 550 of suction nozzle 550 inclinations.For example, this is very effective when position that narrows down because of the place ahead obstacle object plane of cleaning.When changing the direction of suction nozzle 550, changed the direction of roller 1200, thereby can easily change the direction of suction nozzle 550 as the rotation vehicle steering.

Dotted line is indicated as shown in fig. 1, and when handle 301 reversed 90 °, effect along continuous straight runs that also can be by pipe joint 1530 tilted the direction of suction nozzle 550 90 °.In this case, the action roller 1264 of suction nozzle 550 stretches out from the bottom by the effect of pipe joint 1530.Owing to support suction nozzles 550 by action roller 1264 and front wheel 1261, thus when suction nozzle with regard to aside the time, (above-mentioned horizontal direction V1) mobile suction nozzle 550 along the longitudinal direction.

In addition, make in the raised zones that pipe joint 1530 is surrounded on suction nozzle 1000 owing to the angle of height direction Y last second rotating shaft 1535 becomes 90 °, thereby make the suction nozzle 550 in the present embodiment be very beneficial for cleaning narrow slit.In addition, under this user mode, brush side tube connector 1532 is placed central authorities' one sides (wall side) of 550 pairs of angular direction of suction nozzle, thereby can reduce the swing of suction inlet, can improve exercise performance along horizontal direction.

In addition, in the suction nozzle 550 in the present embodiment, two rotating shafts of pipe joint 1530 can be distinguished independent rotation or rotation simultaneously, and bar structure is very compact like this, has improved the collection ability, does packaging size forr a short time.The angle that Figure 15 expresses height direction Y last first rotating shaft 1535 is 0 ° and the angle of horizontal direction X second rotating shaft 1533 is 180 ° a situation.Under this posture, suction nozzle main body 1000 central authorities in a longitudinal direction install outlet connecting pipe 1532 to such an extent that resemble " topknot ".The angle that Figure 16 expresses height direction Y last first rotating shaft 1535 is 90 ° and the angle of last second rotating shaft 1533 of horizontal direction X is 90 ° a situation.Under this posture, on a side of leaving suction nozzle main body central authorities on the longitudinal direction, installation outlet tube connector 1532.Under the posture shown in Figure 16, pipe joint 1530 is surrounded among the raised zones of suction nozzle main body 1000 in addition, thereby the installation region can be done littler than the installation region under the posture shown in Figure 23.

As mentioned above, in the present embodiment,, thereby can do collection or packaging space forr a short time for collection or packing are suitably selected aforementioned two postures and can be collected or pack vacuum cleaner.In addition, when under aforementioned posture, locking mechanism being set at when being lockable, can make the collection posture keep stable.

Below, the operation principle of suction nozzle 550 in the present embodiment is described with reference to Figure 17.In fact vacuum cleaner 1 in the present embodiment can be converted to the rotation P1 of the twisting action of handle 300 the rotation P2 of suction nozzle main body 1000.Operation principle can be described, for example, as follows.

Figure (a) is the side view that concept nature is expressed the suction nozzle 550 of state A1 when the angle on the height direction Y is 45 ° and the state A2 when angle is 90 °, and scheming (d) is when the side view of the state A3 when 45 ° change to about 30 ° of the angle on the above-mentioned height direction Y.

The state A1 of figure (b) expression when the angle on the height direction Y is 45 ° and the top view of the suction nozzle 550 of the state A0 when twisting action P1 is set at 90 ° are schemed the front view that (c) expresses suction nozzle 550 under the state A0 when twisting action P1 is 90 °.

In figure (a), in the present embodiment, the surface of revolution F1 of first rotating shaft 1533 between the tubular axis B2 of the tubular axis B1 that is located at the brush side tube connector 1531 that is parallel to each other and outlet connecting pipe 1532 and tubular axis B1 and B2 are be arranged in parallel.Experimental verification in the present embodiment shows that the rotation P1 (rotation tubular axis B2) of handle 300 twisting actions is converted to the rotation P2 of suction nozzle 550 around intersection point G1, and extended line F2 passes surface of revolution F1 and ground intersects at intersection point G1.Therefore, be under 90 ° the state in the angle on the height direction Y, extended line F2 passes the intersection point G2 that surface of revolution F1 and ground intersects and is positioned at right side, handle 300 below, thereby can be easy to carry out the rotation of the P1 of handle 300 twisting actions.

On the other hand, shown in figure (d), under the state A3 that the angle on the height direction Y becomes littler, intersection point G3 is far, thereby can not finish the rotation P2 of suction nozzle 550, unless reverse rotation P1 with very large masterpiece.In addition, as shown in the figure, when make on the height direction Y angle very hour, the extended line F2 that passes surface of revolution F1 does not intersect with ground, so that can not finish the rotation P2 of suction nozzle 550.

In the operation principle in explaining present embodiment, fixedly suction nozzle 550, and rotation is moving handle 300 also, compare the first state A1 and the end-state A0 of rotating operation then.[0116]

At first, as figure (a) with (b) as shown in, under the first state A1, extended line F2 is passed the crossing intersection point G1 in surface of revolution F1 and ground is located at the central authorities that approximately are positioned at suction nozzle 550.But as figure (b) with (c), when when making twisting action P1 handle 300 and move to end-state A0, extension line F2 passes the crossing intersection point G0 in surface of revolution F1 and ground and is positioned on the side of suction nozzle 550 on the longitudinal direction.That is, under normal duty, handle 300 is operated up to a precalculated position by the user, thereby by the intersection point G1 that is rotation P2 center is moved to the rotation P2 that G0 carries out suction nozzle 550.

When specifying, if along the turning effort of arrow E 1 steering handle twisting action P1 on handle 300, prevent then that at first the suction nozzle main body that tends to rotate according to twisting action P1 1000 rotate around ground, so that first rotating shaft 1533 is around oblique surface of revolution F1 rotation and like and leave such work towards arrow E 2 directions.On the other hand, the work of second rotating shaft 1535 is so that accept twisting action P1 on the suction nozzle 550 whole bottoms but also slowly rotation, that is, 1535 actions of second rotating shaft are so that by following and the angle of interlocking on first rotating shaft, the 1533 increase height direction Y of oblique surface of revolution F1 rotation.Therefore, suction nozzle 550 rotates along the direction of arrow E 3 by the middle position of rotation P2 is changed to G0 from G1.

[second embodiment]

Figure 18 and 19 expresses another embodiment of vacuum cleaner of the present invention.Figure 18 is the profile of suction nozzle, and Figure 19 is the fundamental diagram of suction nozzle.In when explanation, give same numeral for each and the same or analogous part of part shown in the embodiment of front and will economize the slightly explanation of repetition.

Suction nozzle 550 among suction nozzle 560 in the present embodiment and first embodiment is different and other structures are similar identical with first embodiment on the surface of revolution F1 this point of first rotating shaft 1533 that tilts.In suction nozzle 560, the anglec of rotation of rotation P2 that can make suction nozzle 560 is greater than the anglec of rotation of the twisting action P1 of handle 300.

In Figure 18, suction nozzle 560 made to be set to 0 inclination angle to surface of revolution F1 so that the surface of revolution F1 of first rotating shaft 1533 between brush side tube connector 1531 tubular axis B1 that are parallel to each other and outlet connecting pipe 1532 tubular axis B2 is higher than the end side of outlet connecting pipe 1532 and is lower than outlet connecting pipe 1532.According to present embodiment, first rotating shaft 1533 is set at inclination surface of revolution F1, the pivot of first rotating shaft 1533 so that tilt, thereby can make the transmission passage of outlet connecting pipe 1532 mutually continuous with an oblique transmission passage, thereby can make the whole transmission passage of tube connector 1533 not have bigger bending gently continuously with the transmission passage of brush side tube connector 1531.Therefore, can reduce the obstruction and the noise of dust.

In addition, in the present embodiment,, also the rotation P2 of suction nozzle 560 can be set to 90 ° even upright relative and be suitable under the straight-line state not the twisting action P1 of handle 300 is rotated to 90 ° at handle 310 and suction nozzle 560.Therefore, just handle suction nozzle 560 significantly by one of handle little action.Hereinafter with reference to Figure 19 this operation principle is described.

In Figure 19, figure (a) is the state A1 of concept nature when expressing height direction Y upper angle and being 45 ° and the side view of the suction nozzle 560 of the state A2 of angle when being 90 °, figure (b) be when being illustrated in height direction Y upper angle and being 45 ° state A1 and under state A1 the top view of the suction nozzle 560 under the state A0 during with the angle initialization to 90 of twisting action P1 °, the front view of suction nozzle 560 under the state A0 when angle that figure (c) is illustrated in twisting action P1 is 90 °, figure (d) is partial enlarged drawing of figure (b).

Among the figure (a), still in the suction nozzle 560 in the present embodiment, adopt and the identical method of method that suction nozzle among first embodiment 550 is adopted, experimental verification shows, the rotation P1 of handle 300 twisting actions (rotation tubular axis B2) is converted to suction nozzle 560 and passes the rotation P2 that the crossing intersection point G1 in surface of revolution F1 and ground carries out around extension line F2.But, it is different with first embodiment, because surface of revolution F1 tilts, becomes farther so extension line F2 passes the crossing intersection point G1 in surface of revolution F1 and ground.Therefore, be under 90 ° the state A2 in the angle on the height direction Y, extension line F2 passes the intersection point G2 that surface of revolution F1 and ground intersects and is positioned at 300 times right side of face of handle.But, if surface of revolution F1 tilts not very bigly, then can be easy to carry out the rotation of handle 300 twisting action P1.According to angle 0, intersection point G2 is right side below tubular axis B2 directly.

On the other hand, under the state that the angle on the height direction Y becomes littler, extension line F2 passes angle that surface of revolution F1 do not intersect with ground greater than the angle among first embodiment, so that second embodiment is applicable to operating frequency condition with higher under the bigger posture of height direction Y upper angle.

Still in the present embodiment, employing and the identical method of method that first embodiment is adopted, fixedly suction nozzle 560, rotate and moving handle 300, compare the first state A1 and the end-state A0 of rotating operation then.At first, as figure (a) with (b), under the first state A1, extension line F2 passes the front portion that the crossing intersection point G1 in surface of revolution F1 and ground is positioned at suction nozzle 560.But as figure (b) with (c), when when adopting twisting action P1 handle 300 to move to end-state A0, extension line F2 passes the crossing intersection point G0 in surface of revolution F1 and ground and is positioned on the side of suction nozzle 560 on the longitudinal direction.

In other words, the basic functional principle of present embodiment is identical with the basic functional principle of first embodiment.But what suction nozzle 560 was very big is characterized as shown in figure (b), and under end-state A0, the angle of horizontal direction X upper handle 300 is greater than 90 °.In normal operation, by user's control crank 300 up to a precalculated position, so that the rotation P2 of suction nozzle 560 can be in the state shown in the dotted line.Therefore, when the twisting action P1 of handle 300 half-twist, suction nozzle 560 rotations are above 90 °.That is, even twisting action P1 half-twist not also can make the rotation P2 of suction nozzle 560 be decided to be 90 °.

Twisting action P1 expands rotation P2 to and causes by as shown in figure (d) the surface of revolution F1 of first rotating shaft 1533 being tilted to angle 1.Angle 1 is 0 ° under the handle 300 erectility A2 shown in figure (a) and comparison (b), and increases at state A0 inferior horn 1.That is, when handle 300 was carried out twisting action P1 at the lower position place, it can be with a very little twisting action P1 than handle suction nozzle 560 to a greater degree when handle 300 is carried out twisting action P1 at the place, high position.And when the angle of surface of revolution F1 increases, can obtain same effect.
