Description
Technical field
The present invention relates to the ground suction nozzle of general electric household sweeper.
Background technology
Figure 16 opens 1st conventional example of the existing electric cleaning device ground of clear 61-240929 communique disclosure with suction nozzle to Figure 20 shows that as the spy, Figure 16 is its stereogram, Figure 17 is its bottom view, Figure 18 is the side view of the state when cleaning carpet with this ground suction nozzle, Figure 19 is the side view of the state during with this ground suction nozzle cleaning floor, the situation that Figure 20 person of being to use uses this suction nozzle to clean.
Among Figure 16 to Figure 20, label 1 is to be roughly rectangular upper shell, and label 2 is same lower houses, and they engage by the damper 3 that soft material forms, and last lower house 1,2 and damper 3 have constituted suction nozzle main body 15.Label 4 is elbows that general curved becomes " く " font, and the one end is with can the mode of rotation is chimeric freely in vertical plane with respect to last lower house, and the other end is fitted on the tube connector 5.Label 6 be with can be on the direction identical with elbow 4 directions pointed freely rotation mode be installed in front vehicle wheel on the lower house 2, this wheel is mounted to the determining deviation that can guarantee between lower house 2 and the ground.
Label 7 be by the length direction along lower house 2 form groove constituted, it be the outer end be open state the suction wind path and with from the suction nozzle right-hand member to the roughly linearly mode form of left end.The position, center that sucks wind path 7 is connected with suction inlet 8, forms the wind path that links to each other with the dust storage chamber of electric cleaning device main body 18 inside by elbow 4, tube connector 5 and flexible hose 17 with hand-held part 16.In addition, the brush body 10 that forms of planting is arranged on the rear that sucks wind path 7 lip sheet of being made by flexible materials such as rubber 9 and hairbrush bunchy, and is roughly wide with the width of suction nozzle, and lip sheet 9 and brush body 10 can be regulated by adjusting body 11 from the amount that lower house 2 stretches out.Adjust body 11 and can be " carpet " or " floor and matting " and carry out handover operation according to swept surface.
When with the ground suction nozzle of the 1st conventional example carpet being cleaned, operation is adjusted body 11 so that lip sheet 9 and brush body 10 are state shown in Figure 180, is about to the inside that lip sheet 9 is recovered to lower house 2, and brush body 10 is highlighted longways to the below of lower house 2 is long.So soft brush body 10 is deflection and be in the state that is clipped between lower house 2 and the carpet significantly as shown in the figure, to reduce ground suction nozzle frictional resistance when mobile on carpet.
And during with the ground suction nozzle cleaning floor of the 1st conventional example, body 11 is adjusted in operation makes lip sheet 9 and brush body 10 be the state of Figure 19, and promptly lip sheet 9 and brush body 10 are all to the outstanding part of weak point in the below of lower house 2.So lip sheet 9 and ground Elastic Contact are closed the rear of suction inlet 8 by lip sheet 9,, thereby obtain stronger suction air-flow with the vacuum at raising suction inlet place.On the other hand, outstanding short brush body 10 becoming strong and can fully support ground suction nozzle, so thereby can match with front vehicle wheel 3 guarantee and ground between keep a determining deviation, prevent lower house 2 scuffing ground.
Like this, exchanging whole 11 according to the kind of swept surface carries out after the above-mentioned handover operation, the user just can hand the hand-held part 16 of flexible hose 17 as shown in figure 20, makes suction nozzle carry out dust suction with the front and back action on identical direction of bend pipe 4 to ground.Because the length direction and the direction of action of ground suction nozzle are perpendicular, so cleaning face broad can effectively clean.Because front vehicle wheel 6 is along towards the direction of action rotation, so the light and front vehicle wheel 6 of operation and brush body 10 can not damage ground when mobile.
No matter be the ground dust or the dust of suction nozzle side, all the action along with the fore-and-aft direction of ground suction nozzle is inhaled in the suction wind path 7 that is provided with ground suction nozzle widely, and is inhaled in the dust storage chamber of electric cleaning device main body 18 through suction inlet 8, elbow 4, tube connector 5, flexible hose 17.
Being located at brush body 10 its formations that suck wind path 7 rears can catch on the line hair on the carpet and caught, because that the width of brush body 10 is arranged to suction nozzle is wide, so the hair that can residually not roll off the production line.
Figure 21 is a bottom view of opening the 2nd routine ground suction nozzle of the existing electric cleaning device ground suction nozzle that flat 3-195526 communique disclosed as the spy, and among the figure, the part that is equivalent to aforementioned the 1st conventional example is all put on identical numbering.
Among Figure 21, label 21 be provided in a side of lower house 2 about on the end can 360 the spherical castor that rotates freely of degree.The front and back of suction inlet 8 are provided with the feather 22 that two ends are outside extended mode configuration, and feather 22 is by being installed in a plurality of positions with the contacted height in ground in the mode that is provided with slit 23.
The ground suction nozzle of above-mentioned the 2nd conventional example can rotate freely by 360 degree because of its spherical castor 21, and old place face suction nozzle can also be oblique and horizontal mobile except moving forward and backward, thereby improved the free degree of operation.In addition, because feather 22 contacts with ground, the feasible vacuum of the vacuum part 24 of the suction inlet 8 that feather 22 is fenced up that comprises increases, and the dust suction performance is improved.Even for the dust at position, the peripheral the place ahead of suction nozzle, also can suck from the slit being located at feather 22 23.
Yet, for with elbow 4 relatively suction nozzle main body 15 in the vertical plane freely in addition chimeric and the 1st conventional example of installing of the mode of rotation, because of the length direction of ground suction nozzle horizontal, so during the also narrow part of the transverse width of the interval geometric ratio ground suction nozzle between cleaning furniture and the furniture, ground suction nozzle can not be stretched cleaning face, even further can only make ground suction nozzle that inclination is arranged slightly elbow 4 sides yet.It is narrow slightly that transverse width becomes, and still can't stretch in the interval,, ground suction nozzle must be unloaded from tube connector 5 for this reason, changes the narrow slit suction nozzle.
Thereby though this problem can by Figure 22 for example and as shown in Figure 23 with elbow part 4A from vertically be inserted on the suction nozzle main body 15 with elbow part 4A with can with horizontal plane that suction nozzle main body 15 parallels in do 90 degree rotations modes install and solve, but because in this case, lip sheet 9 and brush body 10 will be in the state that parallels with the moving direction of ground suction nozzle and play the baffle of ground suction nozzle side, therefore can produce the dust that not only can not inhale the wall limit and also when inhaling carpet with the residual such new problem of wired hair.Have again, because the axle of front vehicle wheel 6 is to install with the common moving direction (laterally long state uses down) of ground suction nozzle with meeting at right angles, therefore, when making suction nozzle main body 15 be as shown in Figure 22, have the edge that wheel 6 can not rotate, not only operate heavy but also front vehicle wheel 6 and will scratch problems such as ground vertically for long (moving direction of suction nozzle is for long).Have suction nozzle this class problem, that in respect to the horizontal plane of suction nozzle main body, elbow is only carried out angle adjustment and can list the suction nozzle shown in for example real public clear 45-23188 communique and the real public clear 42-18061 communique.
On end about lower house 2, be provided with can 360 the spherical castor 21 that rotates freely of degree, and be provided with feather 22 in the front and back of suction inlet 8, with regard to the 2nd conventional example that a plurality of positions at one group of (preceding group) feather 22 are provided with slit 23, exist such problem: with above-mentioned the 1st conventional example similarly, the feather 22 of another group (back group) will work as baffle, not only can not inhale the dust at place, wall limit, and because the craspedodrome of spherical castor 21 is poor, so be difficult to ground suction nozzle is operated, indiscriminately ad. as one wishes the mobile ground suction nozzle can feel that then arm is gruelling if move by force.
In addition, be set with felt or the suction nozzle of the hairiness body of planting, also exist operation on carpet and become very heavy even ground suction nozzle such as can not move at problem for common.

As shown in Figure 8, swivel plate 34 in its bottom surface roughly center place be provided with suction inlet 34d, and to be formed with suction inlet 34d be center and the 1st wind path 34e T-shaped intersection, that be communicated with suction inlet 34d and the 2nd wind path 34f, on the trizonal lower surface that is divided into by these T shape wind paths 34e, 34f, be equipped with respectively towards with wheel 41a, 41b, the 41c towards the rotation of identical direction of elbow 37.Wheel is configured by two of front sides (wheel 41a, 41b), rear side one (wheel 41c), usually the three-point support suction nozzle main body 30 that is constituted with these wheels 41.In addition, the rear of the suction inlet 34d on the lower surface of swivel plate 34 also is provided with a transversely arranged row brush body 42, and brush body 42 can rotate in horizontal plane with swivel plate 34 with being integral.
The lower surface of lower house 32 be provided with suction inlet 34d be the center towards length direction form and the outer end be opening horizontal suction wind path 43 and with suction inlet 34d be the center, with laterally suck wind path 43 and be vertical suction wind path 44 that the outer end of decussation is opened; Under the common sweeper mode, the wind path 44a and the horizontal wind path 43 that sucks that vertically suck the place ahead that is positioned at suction inlet 34d of wind path 44 are connected with T shape wind path 34e, the 34f of swivel plate 34, under the narrow slit sweeper mode, the square before wind path 43a of suction inlet 34d that is positioned at that laterally sucks wind path 43 is connected with T shape wind path 34e, the 34f of swivel plate 34 with vertical wind path 44 that sucks; Under above-mentioned connected state, the flexible hose that the suction inlet 34d that has formed spin flap 34 does not show through guide plate 35, joint for pipe 36, elbow 37, tube connector 5 and figure and lead to the wind path of the dust storage chamber within the electric cleaning device main body.
In addition, also be provided with brush body 45 at the rear of the lower surface of lower house 32, some overlaps the brush body of this brush body 45 and swivel plate 34 42 in the longitudinal direction.In addition, in the both sides in the place ahead of the lower surface of lower house 32 short brush body 46 of size is installed also.
In addition, in the position of the opposite side on the length direction of lower house 32, promptly on the end of the position that becomes rear side under the narrow slit sweeper mode, be provided with two auxiliary wheels 47 with the trip lever operation part.The installation site of auxiliary wheel 47 is set like this, promptly when the ground suction nozzle is state parallel to the ground auxiliary wheel 47 be positioned at the not contacted height in ground on.
In addition, on last lower house 31,32 and sliding surface 32d that swivel plate 34 contacts, be provided with concavo-convex rib 32e, even there is sand dust to enter these contacts site, in the recess of the rib 32e that also can hide, can prevent that thus sand dust is stuck among the sliding surface 32d and causes swivel plate 34 not rotate.
In addition, the bottom of each keyway 34b, 34c of swivel plate 34 forms dust-collecting box shown in Figure 9 48, and it constitutes the sand dust that makes in the recess that enters rib 32e and is accommodated by the dust-collecting box 48 of each keyway 34b, 34c by the rotation of swivel plate 34.
In addition,, promptly be formed with the intercommunicating pore 49 that communicates with suction wind path joint for pipe 36 as shown in Figure 9 on the inwall of each keyway 34b, 34c, the sand dust that dust-collecting box 48 is accommodated can be siphoned away by joint for pipe 36 in the bottom of dust-collecting box 48.
Have again, a projection among the projection 36c in the hole 35b of joint for pipe 36 embedding guide plates 35 is provided with centre bore shown in Figure 9 51, thereby make keyway 34b and joint for pipe 36 the suction wind path the two be connected, thus, the sand dust that dust-collecting box 48 is accommodated can be siphoned away.Enumerated the hole that will be used for siphoning away the sand dust that dust-collecting box 48 accommodated at this and be located at the example on swivel plate 34 and the joint for pipe 36 and be illustrated, but in addition also can for example on the guide plate 35 said hole be set directly.
In addition,, be arranged side by side multiple row wind path sulculus 52, made that near the dust the ground suction nozzle leading edge also can siphon away from wind path sulculus 52 in the both sides of the swivel plate 34 at the leading edge place of lower house 32 as Figure 11 and shown in Figure 12.
In the ground suction nozzle of the electric cleaning device of present embodiment, when being in the common sweeper mode that broad ground is cleaned, as Fig. 3, Figure 10 and shown in Figure 11, the 1st keyway 34b of the jam plate 38a of trip lever 38 and swivel plate 34 chimeric and be fixed on the length direction that makes ground suction nozzle and elbow 37 on perpendicular position, this state is kept by helical spring 39.With swivel plate 34 all-in-one- piece wheel 41a, 41b, 41c are installed and are designed to its surfaces of revolution and elbow 37 towards same direction, rotate corresponding to moving forward and backward of ground suction nozzle, therefore, cleaning floor and matting be from needless to say, though on carpet also because the effect of wheel can make operation light.
When being in common sweeper mode, because being positioned at the square before wind path 44a of suction inlet 34d in vertical suction wind path 44 of lower house 32 and laterally sucking wind path 43 is to be connected with T shape wind path 34e, the 34f of swivel plate 34, therefore, ground dust can be along with moving forward and backward of suction nozzle from wind path 44a and laterally suck wind path 43 and be inhaled into from the suction inlet 34d of swivel plate 34, again in the flexible hose that guide plate 35, joint for pipe 36, elbow 37, tube connector 5 and figure do not show is introduced into dust storage chamber in the electric cleaning device main body through T shape wind path 34e, 34f.At this moment, because the dust in ground suction nozzle the place ahead is concentrated towards suction inlet 34d by the wind path 34f that is located between wheel 41a, the 41b, therefore, things such as line hair can not be wound on wheel 41a, 41b and their rotating shaft.
Be located at the brush body 42 of swivel plate 34 1 sides of suction inlet 34d rear side and on the whole width of ground suction nozzle, arrange altogether, so the line Mao Kewu on the carpet is caught with omitting with the brush body 45 of lower house 32 1 sides.
Secondly, when narrow place is cleaned, the effect that makes the operation part 38b of trip lever 38 overcome helical spring 39 is outwards slided, thereby the jam plate 38a that makes the end as shown in figure 13 deviates from the 1st keyway 34b with the matching relationship of releasing with swivel plate 34, revolve in this state and turn 90 degrees, unclamp operation part 38b when elbow 37 arrives on the length direction consistent location with suction nozzle main body 30 so that elbow 37 is positioned on the position opposite with the operation part 38b of trip lever 38.So the jam plate 38a and the 2nd keyway 34c of trip lever 38a its end under the effect of helical spring 39 are chimeric, thereby ground suction nozzle is fixed on state as Fig. 4, Figure 14 and narrow slit sweeper mode shown in Figure 15.When being in the narrow slit sweeper mode, owing to elbow 37 is positioned on the position opposite with the operation part 38b of trip lever 38, so the operation part 38b of trip lever 38 can not influence mutually with elbow 37.Therefore, down less important when returning to common sweeper mode, be easy to operation part 38b is operated.
When being in the narrow slit sweeper mode, because square wind path 43a and vertical wind path 44 that sucks is connected with T shape wind path 34e, the 34f of swivel plate 34 before being positioned at suction inlet 34d in the horizontal suction wind path 43 of lower house 32, so ground dust will be owing to moving forward and backward of ground suction nozzle from wind path 43a and vertically suck wind path 44 and drink up, again in the flexible hose that guide plate 35, joint for pipe 36, elbow 37, tube connector 5 and figure do not show is introduced into dust storage chamber in the electric cleaning device main body through the suction inlet 34d that T shape wind path 34e, 34f are rotated plate 34.Wheel 41a, 41b, 41c and swivel plate 34 be translation-angle integratedly, and its surfaces of revolution and elbow 37 rotate corresponding to moving forward and backward of ground suction nozzle towards same direction.Therefore, be located at that the brush body 42 of side also rotates in horizontal plane with swivel plate 34 after the suction inlet 34d of swivel plate 34, perpendicular and roughly arrange with the moving direction of suction nozzle with transverse width widely.So the line hair on the carpet does not have omission.In addition, also be formed on the place ahead and left and right directions with respect to the suction nozzle moving direction owing to suck wind path, thus the place ahead and about the dust on wall limit also can suck expeditiously.
