BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner.

[0002]

2. Description of the Related Art FIGS. 3 and 4 show a conventional vacuum cleaner, wherein 1 is a main body of the vacuum cleaner, 2 is a suction port provided on the upper surface of one side of the main body 1, and 3 is a suction port 2. A hose 4 which is pivotally and detachably connected to the main body 1 is provided on a lower surface of one side of the main body 1, and a caster-like front wheel which can be swiveled around a rotation shaft 41 is provided on a lower surface of the other side of the main body 1. It is the rear wheel that was hit.

By the way, since the vacuum cleaner is mainly used while moving, it is desirable that the main body 1 be pulled by the connecting hose 3 so that the main body 1 can travel lightly and the direction can be changed quickly. The direction of the main body 1 is determined by the direction of the leading front wheel 4, and in order to quickly change the direction of the main body 1, it is necessary to have a configuration capable of changing the direction of the front wheel 4 quickly. However, according to the above configuration, since the hose 3 and the front wheel 4 are not connected to each other, even if the hose 3 rotates in a new direction, the front wheel 4 is still oriented in the conventional direction.
An extra traction force was required on the main body 1 to turn the front wheels 4 in a new direction.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks and to provide an electric vacuum cleaner in which the front wheel is interlocked with the movement of the hose and the direction of the main body can be swiftly changed.

[0005]

In order to solve the above-mentioned problems, in the present invention, a suction port is provided on the upper surface or the bottom surface on one side,
Electric cleaning with a main body having a rear wheel on the bottom surface on the other side, a connection cylinder body having a hose attachment / detachment port that is pivotally attached to the suction port, and a front wheel pivotally supported by the connection cylinder body. Machine,
The rotating shaft of the connecting cylinder was formed vertically, and the axle of the front wheel was made to coincide with the rotating shaft.

[0006]

According to the above construction, the suction port provided in the main body rotatably pivotally attaches the connection cylindrical body having the hose attachment / detachment port to intake air. The connecting cylinder body has a rotation shaft formed vertically and supports the front wheels integrally. The front wheel aligns the axle with the rotation axis of the connecting cylinder to facilitate rotation of the connecting cylinder.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 6 denotes a main body of the electric vacuum cleaner, in which a suction port 7 is provided directly on the bottom surface on one side, and a plurality of rear wheels 8 are provided on the bottom surface on the other side. Reference numeral 9 denotes a connecting cylinder pivotally attached to the suction port 7 so that a hose attaching / detaching port 10 is provided at one end thereof in an obliquely upward direction, and a plurality of front wheels 11 are provided at the bottom.
Is pivotally supported.

The connecting cylinder 9 is pivotally attached to the suction port 7 with the rotating shaft 13 being vertical, and the front wheel 11 is mounted so that the axle 12 is aligned with the rotating shaft 13. In addition,
A handle 14 is provided on the upper surface of the main body 6 so as to be freely foldable.

FIG. 2 shows another embodiment of the present invention.
Reference numeral 15 denotes a main body of the electric vacuum cleaner. The suction port 16 is provided directly on the upper surface of one side, and the rear wheels 17 are provided on the bottom surface of the other side. Reference numeral 18 denotes a connecting cylinder pivotally attached to the suction port 16 so as to form a rotary shaft 19 vertically, a hose attaching / detaching port 20 at one end, and an arm 21 toward the bottom surface of the main body 15. It extends all together. The arm 21 has a protrusion 22 integrally formed on the tip end thereof so as to protrude upward, and the protrusion 22 is pivotally supported on the bottom surface of the main body 15 so as to be aligned with the rotation shaft 19, and the axle 24 is rotated immediately below the protrusion 22. It has a front wheel 23 matched with the shaft 19. According to this, since the arm 21 can be used as a handle, a dedicated handle can be omitted.

[0010]

As described above, according to the present invention, since the direction of the front wheel and the direction of the hose are always the same, the main body can be swiftly turned without applying excessive force.
Moreover, since the hose attachment / detachment port is provided at a low position close to the floor surface, stability is increased and the body can be prevented from falling.
