When the line end C of switch 59 in Fig. 7 being pulled by situation, the power supply of giving motor 2 and electric blower 61 just is cut off, and the dust suction cleaning will stop.The rotating speed of the motor 2 when switch 59 is pulled C line end among Fig. 7,75% of the rotating speed of the motor 2 when being approximately switch 59 and pulling C line end among Fig. 7.
When the operator wants to clean the surface to be cleaned of floor or matting mat etc., this suction nozzle be can use, front side flexible elements 11 and rear side flexible element 12 and the contacted length in surface to be cleaned (as shown in Figure 1) kept because be separately positioned on the front side flexible element 11 of front and rear and the rear side flexible element 12 of the suction inlet 4 of head sucting body 1.Front side flexible element 11 and rear side flexible element 12 are curved (as shown in Figure 3) by the surperficial air stream that is produced by vacuum cleaner main body 44 separately.
The size of the gap A that produces owing to flexible element is crooked between front side flexible element 11 or rear side flexible element 12 and surface to be cleaned becomes with the size of the air capacity in the vacuum cleaner main body 44.Air capacity in vacuum cleaner main body 44 more for a long time, in other words, when the filtration members in the vacuum cleaner main body 44 was not blocked, it is big that gap A becomes.If owing to the filtration members in the vacuum cleaner main body 44 is blocked when air capacity in the vacuum cleaner main body 44 is diminished, then gap A just diminishes.As mentioned above, the speed air flow in the suction inlet 4 of inflow head sucting body 1 keeps constant along with the change of gap A.
The setting size of the many hole slots 41 that form on front side flexible element 11 is as follows.Pressure distribution in the suction nozzle of existing vacuum cleaner is a core pressure height and the pressure at both ends is low, shown in the curve P among Figure 10, as making comparisons with the pressure distribution of this vacuum cleaner commonly used, in pressing the vacuum cleaner of suction nozzle of the present invention, pressure distribution is average, whole transverse width upward pressure at suction nozzle is all higher, shown in the curve Q among Figure 10.
The setting of the size of front side flexible element 11 is so in one example: the constant height of front side flexible element 11, and its width W, W and W diminish pari passu towards the both ends of front side flexible element 11, as shown in Figure 8.
It is so in another example that the size of front side flexible element 11 is set: the width W of front side flexible element 11 is constant, and its height H, H and H diminish pari passu towards the both ends of front side flexible element 11, as shown in Figure 9.
According to the pressure distribution shown in the curve Q among Figure 10 of the present invention, produce strong suction force along the whole length direction of the suction inlet 4 of head sucting body 1.
When the operator wants to utilize rotating brush 3 cleaning carpets etc., because the front side flexible element 11 of head sucting body 1 is to be connected in more cave in into sunk part 63 of basal surface than head sucting body 1, so head sucting body 1 can be worked easily and successfully.
For example, less from the resistance of carpet even when front side flexible element 11 contacts the fur of carpets owing to front side flexible element 11 prolongs, so head sucting body 1 can be operated easily and smoothly.
Place the suction guide plate 42 between front side flexible element 11 and the suction inlet 4, to the inner inclination of head sucting body 1.Suction guide plate 42 can not block the bending of front side flexible element 11.
In addition, suck guide plate 42, can make when front side flexible element 11 and run into threshold, prevent that it from contacting with rotating brush 3 by when its inboard pushes owing to be provided with.Suck guide plate 42 owing to be provided with, have furred carpet,, can avoid making itself and rotating brush 3 to twine as a kind of rough carpet.
When the lip-deep beam 19 in the dead ahead that is contained in head sucting body 1 bumped against indoor wall or furniture, beam 19 was with regard to owing to the thrust of wall or furniture is out of shape.The bottom 19a of beam 19 and the root of front side flexible element 11 are pushed by the inboard to them respectively.
Because the gap A between front side flexible element 11 and the surface to be cleaned is big and what are irrelevant with sucking air capacity, so bigger solids grain is as peanut, with regard to not being retained in the back in bight, room but successfully be inhaled in the suction inlet 4 of head sucting body 1.
In addition, front side flexible element 11 is to be loaded on the axis of steamboat 9 and 10, and like this, even be uneven on the surface to be cleaned, the gap A between front side flexible element 11 and the surface to be cleaned also is constant.
When the air suction force effect that the suction inlet 4 that is subjected to head sucting body 1 produces, front side flexible element 11 is inboard when crooked towards it, and its point has covered a part of suction inlet 4.So the open region of suction inlet 4 just diminishes, so the air suction force strengthened, and large-sized solids grain can more successfully be sucked in the suction inlet 4 of head sucting body 1.
After front side flexible element 11 wearing and tearing, because front side flexible element 11 separates separately with beam 19, and be the recess 63 that removably is loaded on the antetheca of head sucting body 1, so, can change front side flexible element 11 easily and irrelevant with beam 19.
Because front side flexible element 11 places recess 63, and this part be on the bottom of head sucting body 1 on the position of retread (moving back), so, comprise that the front side flexible element 11 of an elastomeric material is very little because of the crooked ratio of distortion.Owing to do not have power of enforcement on the root of front side flexible element 11, so even crooked, its life-span also is long.In addition, the power along fore-and-aft direction operation head sucting body 1 is very little.
Even be subjected to power of enforcement when front side flexible element 11, suck guide plate 42 and can be used as the wall that can accept power of enforcement, so, can prevent that front side flexible element 11 from being torn to shreds or damaging.
In addition, jubate rough carpet is easy to snarl rotating brush 3.At this moment, owing to becoming mildewed of this carpet can be pushed to the outside, so, suck guide plate 42 and can prevent from rotating brush 3 and become mildewed to snarl.Even when being used in shag carpet, the change in rotational speed of rotating brush 3 also can be very little.
Rotating brush 3 can be transferred to the rotating speed that is suitable for using with high or low rotating speed.Even when carrying out the dust suction operation on the matting mat, the rotating speed of rotating brush 3 also is lower.Therefore, the same when on matting, cleaning with the effect of cleaning at ordinary times, can not damage the matting ground dishes served at a feast.
Because the rotation status of rotating brush 3 is shown in the top of head sucting body 1, the operator just can see operating condition at once, whether has damaged the floor by rotating brush 3 in floor-cleaning, and perhaps rotating brush 3 has been with foreign matter and is stuck and has not changeed.Like this, rotating brush 3 can use under the normal operation condition all the time.
The rotating brush bearing 29 and 30 of rotating brush 3 is held under the setting pressure, and rotates with the predetermined constant direction.Even some imbalances take place in rotating brush 3, cause by above-mentioned imbalance, the vibrating noise in rotating brush 3 also can be limited.
Owing to second flange section 28 on second belt pulley 27 that is contained in rotating brush 3 is to install towards the inboard of rotating brush 3, so, even under the situation that rotating brush 3 has been taken off, synchronous belt 64 does not hook on second flange section 28, and it also can successfully unload it when safeguarding head sucting body 1.
In addition, be placed on the inside owing to stretch out the power line that extends to the outside, so power line can not tangle on the leg of the bottom of desk or furniture from crooked coupling head 6.Therefore, can clean the surface to be cleaned in lower and narrower place, and the security that has improved power line, can not produce extra extraneous power of enforcement at the root of power line.
In addition, the structure of the knuckle section of crooked coupling head 6 among the present invention, head sucting body 1 is as follows.Forming the formation of shape of protective cover of the outer cover of crooked coupling head 6, is to engage with the cylindrical sleeve part 53 of sleeve pipe 18 sides.And the above and below structure installed to crooked coupling head 6 one sides together.Even act on crooked coupling head 6 knuckle sections as big external force, the bonding part on this part can not thrown off yet, and its assembled portion can not skid off beyond the position yet.
In addition, because internal wire 48 is arranged by free shape, and there is not power of enforcement in the space between first protective cover 49 and crooked coupling head 6, these electric wires 48 can both move freely along the upper and lower, left and right direction, like this, the folding life-span of these internal wires 48 is also just improved greatly.
