2. Description of the Related Art A conventional electric floor suction tool (hereinafter referred to as "suction tool") is
The structure shown in Japanese Patent Laid-Open No. 61-10594 is common.

The configuration will be described below with reference to the drawings.

In FIG. 6, the suction tool body 1 has a rotary brush chamber 3 having a rotary brush 2 built in the front portion thereof, and a connection pipe 4 communicating with the motor 4 of the rotary brush drive source and the rotary brush chamber 3 at the rear portion thereof. is doing.

Reference numeral 5 is a bearing arranged at both ends of the rotary brush 2, and 6 is a belt installed between the rotary brush 2 and the motor 4.

A power cord 7 supplies power to the motor 4 and is connected to a lead wire 8 from the motor 4.

The suction tool body 1 is formed of upper and lower body members.

Problems to be Solved by the Invention However, both ends of such a suction tool body 1 are bearing holding portions for holding the bearings 5 of the rotating brush 2, and therefore cannot be cleaned by the rotating brush 2 to prevent dust. Was left. Especially in the corner of the room, there was a problem that it could not be cleaned.

Means for Solving the Problems The present invention is to eliminate the above-mentioned conventional drawbacks, and comprises a rotary brush which is composed of a main brush and an auxiliary brush for scraping up dust on the floor surface, and a drive source for the rotary brush, Bearings are respectively provided between the main brush and the auxiliary brush and at the other end of the main brush, and the bearings are held by a bearing holding portion provided on the inhaler body, and a floor is provided on a lower surface of the bearing holding portion on the auxiliary brush side. A flat brush for catching surface dust is provided, and a recess is formed in the rear portion of the flat brush so that the intake airflow from the auxiliary brush intake port provided in the auxiliary brush flows to the main brush intake port provided at the lower part of the main brush. It is formed and communicated.

Further, in the above description, the flat brush is attached so as to be inclined so that the front approaches the floor.

Effect According to the above invention, the auxiliary brush rotates in conjunction with the main brush of the rotating brush to scrape up dust on the floor surface, but by operating the suction tool back and forth, it is provided on the lower surface of the bearing holding portion of the main body. With the flat brush, dust is also caught, and the dust is moved from the concave portion to the suction port by the suction of the electric vacuum cleaner and sucked.

In this way, the floor surface can be cleaned up to the end of the suction tool, and the corners of the room can be efficiently cleaned without generating dust residue.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In the figure, 10 is an electric blower with a built-in electric blower and a dust bag, 11 is a hose, and 12 is an extension pipe, which is provided at the rear of the electric vacuum cleaner 10 and the suction tool body 13 of the electric floor suction tool. Are connected to the connecting pipes 14 respectively.

15 is a moving wheel, and 16 is a handle.

The suction tool body 13 has a rotary brush chamber 18 having a rotary brush 17 built in the front thereof, a motor chamber 20 having a motor 19 built in one of its rear sides, and a resistor 21 for protecting the motor 19 on the opposite side thereof, a positive characteristic Each has a circuit room 25 provided with a printed circuit board 24 incorporating electric components such as a thermistor 22, a current fuse 23 for preventing ignition and smoke generation, and an intake passage 26 communicating with the rotary brush room 18 and the above-mentioned in the center of the rear part. A connecting pipe 14 is provided.

Reference numeral 27 denotes a suction port arranged in the lower part of the rotary brush chamber 18, and the rotary brush 17 is seen on the floor surface.

The suction tool body 13 forms an outer shell by the upper body member 28, the lower body member 29, and the brush cover 30 to form the chambers.

A belt 31 is installed between the rotating brush 17 and the motor 19, and transmits the rotation of the motor 19 to the rotating brush 17.

The rotating brush 17 includes a main brush 32, an auxiliary brush 33 and a bearing 34.
The bearing 34 is arranged between the main brush 32 and the auxiliary brush 33 and at the other end of the main brush 32, and is held by the lower body member 29 and the bearing holding portion 35 of the brush cover 30.

The auxiliary brush 33 rotates in conjunction with the main brush 32, and the belt 31 is installed at the end of the main brush 32 on the opposite side of the auxiliary brush 33.

Bristles 36 are planted on the outer circumferences of the auxiliary brush 33 and the main brush 32, a bearing 34 rotatably supports a shaft 37 attached to the main brush 32, and the auxiliary brush 33 is inserted at the end of the shaft 37. I'm wearing it.

Bristles 36 are slantly planted in the auxiliary brush 33, and the bristles 36 are sucked by looking outward from the side end opening chamber 38 in which the side ends of the lower body member 29 and the brush cover 30 are opened. The end of the main body 13 is placed at the very end so that the corner of the room can be surely cleaned. The rigid portion of the auxiliary brush 33 is not projected from the side surface of the suction tool body 13 so that usability and safety are not hindered.

39 is a bypass passage arranged in the upper rear portion of the bearing holding portion 35, which connects the rotating brush chamber 18 and the side end open chamber 38,
The dust scraped up by the auxiliary brush 33 is guided to the rotary brush chamber 18.

Reference numeral 40 denotes a flat brush arranged on the lower surface of the bearing holding portion 35 of the lower main body member 29, the surface of which is brushed to catch dust.

Reference numeral 41 denotes a recess formed so that the bearing holding portion 35 on the rear end side of the flat brush 40 has a gap with the floor surface, and dust caught by the flat brush 40 passes through the recess 41 of the vacuum cleaner 10. It is adapted to move to the suction port 27 by suction.

Further, the flat brush 40 is attached so as to be inclined so that the front side thereof approaches the floor surface, and the trapped dust is easily guided to the recess 41 arranged at the rear portion.

The flat brush 40 is fluffed obliquely so as to catch dust when pulling the suction tool 13 and to separate the dust due to friction with the floor surface when pushing the suction tool 13, so that dust can be effectively sucked from the recess 41. It has become.
