Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor suction tool to which an electric vacuum cleaner body is connected, and more particularly to a floor suction tool capable of improving workability of attaching and detaching a rotary brush.

[0002]

2. Description of the Related Art Conventionally, in a floor suction device, as shown in a cross-sectional plan view of FIG. 6, for example, a brush storage chamber 103 for storing a rotating brush 102 is formed in a front part of a suction device body 101, and a rear part thereof is formed. A motor housing chamber 106 for housing the motor 105 with the connection pipe 104 interposed therebetween, and a motor control board 10
A substrate housing chamber 108 for housing 7 is formed.

The upper surfaces of the brush storage chamber 103, the motor storage chamber 106 and the substrate storage chamber 108 are opened, and the openings are covered by a single removable lid, and the bottom of the brush storage chamber 103 has a suction port. 109 is opened.

The rotating brush 102 is a brush storage chamber 103.
It is arranged in a position facing the suction port 109 inside, and both ends thereof are rotatably supported by shaft supporting portions 111 provided on the suction tool body 101 via bearing portions 110, respectively.

Both bearings 110 are attached to and removed from each shaft support 111 from above, and the motor 105 is attached to one of the bearings 110.
A timing belt 112, which interlocks the rotary brush 102 with the rotary brush 102, is wound.

[0006]

By the way, in this kind of floor suction tool, the rotary brush 102 may be taken out from the suction tool main body 101 in order to remove the lint and the like entwined with the rotary brush.

In such a case, the brush storage chamber 103
It is necessary to remove the upper lid of the rotary brush 102, remove the bearings 110 at both ends of the rotary brush 102 from the shaft support 111, and further remove the timing belt 112 from the end of the rotary brush 102, which is disadvantageous in improving workability. is there.

In addition, when mounting the removed rotary brush 102, it is necessary to reverse the procedure,
It is disadvantageous in improving workability as well as removal work.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a floor suction tool capable of enhancing workability in attaching and detaching a rotary brush.

[0010]

According to the present invention, there is provided a suction tool body having a brush storage chamber, a suction port provided on the bottom surface of the brush storage chamber, and a suction port rotatably disposed in the brush storage chamber. In order to achieve the above-mentioned object, the following measures are taken in the floor suction tool provided with the rotating brush and the drive source that rotationally drives the rotating brush. That is,
The rotating brush has a bearing portion at one end that is supported by the shaft support portion of the suction tool body so that it can be inserted into and removed from the shaft support portion, and at the other end that is rotatably supported by the suction tool body and linked to a drive source. It is characterized by having an engaging portion which is engaged with and disengaged from.

[0011]

In the present invention, the bearing portion at one end of the rotary brush and the shaft support portion of the suction tool body are fitted into and disengaged from each other, and the engaging portion and the bearing body at the other end of the rotary brush are engaged and disengaged.
The other end of the rotary brush can be attached to and detached from the suction tool body regardless of the interlocking mechanism portion that interlocks and connects the drive source and the bearing body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A floor suction tool according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view of an embodiment of the present invention,
FIG. 2 is a plan view with the lid removed.

This floor suction tool forms a brush storage chamber 3 for storing the rotating brush 2 in the front part of the suction tool main body 1, and the top surface of the brush storage chamber 3 is attached to and detached from the suction tool main body 1. The lid 13 is opened and closed, and the other bottom is opened to form a suction port 4.

The rotary brush 2 is arranged in the brush storage chamber 3 so as to face the suction port 4, and both ends thereof are bearing portions 5 and 6.
It is rotatably supported by the suction tool body 1 via.

As shown in the vertical sectional side view of FIG. 3, a motor storage chamber 8 is formed at the rear side of the brush storage chamber 3, and the motor 7 and the rotating brush 2 stored in the motor storage chamber 8 are arranged in the motor storage chamber 8. The timing belt 9 is interlockingly connected.

As shown in the exploded bottom views of FIGS. 2 and 4,
One of the bearings 5 and 6 has one bearing 5 which is the rotating brush 2.
5 is connected to one end of the suction tool body 1 and is fitted into and removed from a shaft support portion 10 provided in the suction tool body 1 from above, and the other bearing portion 6 is rotatably supported by the suction tool body 1 and a part of FIG. As shown in the cross-sectional plan view, a pulley 14 around which the timing belt 9 is wound is rotatably supported on the bearing portion 6.

A taper hole 11 is formed in the pulley 14, and a frustoconical engagement portion 12 formed at the other end of the rotary brush 2 is engaged with the taper hole 11 in a disengageable manner.

In this floor suction tool, when the lid 13 is removed and one end side portion of the rotary brush 2 is pulled upward, the bearing portion 5 is fitted into and removed from the shaft support portion 10, and then the rotary brush 2 is slanted. By pulling upward, the engaging portion 12 is pulled out from the tapered hole 11 of the pulley 14, and the rotating brush 2 is separated from the suction tool body 1.

On the contrary, when the rotary brush 2 is incorporated into the suction tool body 1, the engaging portion 12 of the rotary brush 2 is inserted into the tapered hole 11 of the bearing portion 7, and one end of the rotary brush 2 is attached to the shaft supporting portion 10. The bearing 5 may be fitted into the shaft support 10 by pushing in from above.

Therefore, it is not necessary to attach / detach the timing belt 9 to / from the bearing portion 7, and the workability of attaching / detaching the rotary brush 2 can be improved.

[0022]

As described above, according to the floor suction device of the present invention, the bearing portion provided at one end of the rotating brush without touching the interlocking mechanism for interlocking the rotating brush and the drive source for driving the rotating brush. The rotary brush is attached to and detached from the suction tool body by simply engaging and disengaging the shaft support portion provided on the suction tool body and engaging and disengaging the engaging portion formed on the other end of the rotation brush with the bearing portion supported by the suction tool body. Therefore, the workability of attaching and detaching the rotating brush can be improved.
