Embodiment
It is following that the present invention is described in detail according to Fig. 1 to Fig. 5.
1 for having the vacuum cleaner body of air entry 2, and be connected with an end of flexual flexible pipe 3 at the air entry 2 of this vacuum cleaner body 1, simultaneously, be connected in the tube connector described later 6 that is provided in flexible pipe 3 other ends with prolonging pipe 4 forms, suction cleaner for floor 5 be installed in these prolongation pipe 4 ends with detachable.
6 is the tube connector that is equipped on the other end of aforementioned flexible pipe 3, and this tube connector has the switch 7 of the electric blowing machine not shown in the figures of the aforementioned vacuum cleaner body 1 of control, simultaneously, and at the slightly leg-of-mutton handle portion 8 of being formed with of these tube connector 6 upper side one.
9 for be formed at aforementioned tube connector 6 ends near the breach ditch of the following side relative with handle portion 8, in position corresponding to this breach ditch 9, tube connector 6 axially on an outstanding a pair of axle support 10 that forms axle supporting aftermentioned accessory 13.Aforementioned axis support 10 has slotted hole 11, supplies the axle 15 of accessory 13 described later to slide at this slotted hole 11.12 is the button claw stop that is formed at the downside of aforementioned tube connector 6, and when accessory 13 described later did not use, button ended accessory 13.
13 is the gap accessory when cleaning furniture gap and wall edge etc., and its external diameter is formed internal diameter size slightly together with aforementioned tube connector 6.14 is the axle supporting slice that is formed on an end outer peripheral face of aforementioned accessory 13, and is formed with axle 15 at this supporting slice 14, and this axle 15 is can be free to slide and can be supported on aforementioned axis support 14 by free rotating form axle.16 is aforementioned accessories 13 when not using among the figure, is formed at the leakage hole of aforementioned tube connector 6 one sides of subtend, by the air of taking from this leakage hole 16, can prevent the little load that puts on electric blowing machine of aperture area because of aforementioned accessory 13.Make opening edge that the button claw stop of aforementioned tube connector 6 is fastened on this leakage hole 16 with standing finish 13 and prevent to rotate.
In the above-described configuration, when generally doing the ground cleaning, promptly connect prolongation pipe 4 and suction cleaner for floor 5 uses in flexible pipe 3 ends.
Therefore, when cleaning furniture gap and jamb, wall edge, to prolong pipe 4 unloads with suction cleaner for floor 5, pull down accessory 13 from button claw stop 12, slide into along the slotted hole 11 of axle support 10 between the trip end of a support 10 after the revolution simultaneously, make accessory 13 slide into the root (scavenging machine body one side) of a support 10, make accessory 13 be embedded in week in the tube connector 6.
According to so constituting, when cleaning thin such as the gap of furniture and jamb, prolong pipe 4, accessory 13 is slided and revolution as long as unload, can easily be embedded in the tube connector 6 of flexible pipe 3, compare with pull down the situation that accessory 13 changes from vacuum cleaner body 1, not only improve usability, simultaneously, can be with accessory 13 chimeric being installed on week in the tube connector 6, can prevent that the air between accessory 13 and the tube connector 6 from leaking, can improve air-tightness, prevent the reduction of inspiratory force.
Again,, do not need accommodation space to be set, can prevent the maximization of vacuum cleaner body at vacuum cleaner body 1 by accessory 13 is installed in the tube connector 6.
Then, to Fig. 9 second embodiment is described according to Fig. 6.The part identical with the foregoing description enclosed same symbol and omitted explanation.
In this second embodiment, the openend of tube connector 6 is to be skewed, and away from handle portion 8, following side is then near handle portion 8 at the upper face side that is formed with aforementioned handle portion 8 for it.The 17th, the tab-like following side that is formed in aforementioned tube connector 6, just be formed at axle support near the part of the handle portion 8 of the openend of tube connector 6, be that axle 15 with aforementioned accessory 13 is being supported on this support 17 by free rotating form axle.
According to so constituting, make the sloped-end of tube connector 6, supporting accessory 13 in position axis, so prolong pipe 4, pivotal fitting 13 as long as unload near the handle portion 8 of this inclination, can airtightly accessory 13 be embedded in tube connector 6, not only structure is simple, and accessory 13 can easily be installed, and improves usability, simultaneously, compare the intensity that can increase a support 17 with above-mentioned first embodiment.
Yet, in this second embodiment, the rake of tube connector 6 ends is formed, the upper face side with aforementioned handle portion 8 away from handle portion 8 lower face near handle portion 8, but be set as make tube connector 6 following side away from handle portion 8 upper face side near the rake of handle portion 8, or be set as a sidepiece with tube connector, and also can in the other side near the rake of handle portion 8 away from handle portion 8.Though any situation, rake an axle supporting accessory 13 is set near the position of handle portion 8, all have same effect.
In a second embodiment, by tube connector 6 ends are tilted, and be center steering accessory 13 with axle 15, accessory 13 is embedded in the formation of tube connector 6, but also can make as Figure 10 to the 3rd embodiment shown in Figure 14, with the relative upper face side inner peripheral surface of axle support 17 of tube connector 6, formation 15 is fulcrum with the axle of aforementioned accessory 13, is the circular-arc recess 18 of radius with the external diameter of accessory 13, promptly need not strengthen the external diameter of tube connector 6, only add large diameter, is fulcrum revolution with accessory 13 with axle 15, can be airtight be embedded in tube connector 6, not only structure is simple, can be easy to install accessory 13, improve usability.
And, as Figure 15 to the 4th embodiment shown in Figure 180, relative to end peripheries partly with the axle 15 of accessory 13, formation is the fillet part 19 of fulcrum with the axle 15 of aforementioned accessory 13, the internal diameter of tube connector 6 must not strengthened, only with accessory 13, revolution can be airtight be embedded in tube connector 6, not only structure is simple, and accessory 13 can easily be installed, and improves usability.
Yet, in the various embodiments described above, the formation of accessory 13 is installed, but the side end that is formed at the suction cleaner for floor 5 that prolongs pipe 4 also can at the tube connector 6 of the end that is formed at flexible pipe 3.
