BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric floor suction tool that rotates a rotating brush using a motor.

0002

[Prior Art] In order to clean dust attached to the rotating brush of a floor suction tool, an opening that can be opened and closed with a lid is provided on the top surface of the main body case, or the front part of the main body case is removed and the rotating brush is cleaned. The technology to make it detachable was developed in 1986
It is disclosed in Japanese Utility Model Publication No. 0-94153 and Japanese Utility Model Application Publication No. 124264/1983.

[0003]Also, an electric floor suction tool in which the rotary brush is rotated by a motor is also known, and the above-mentioned conventional technology can be applied to such an electric floor suction tool to remove dust attached to the rotary brush. If you try to clean it, it is very dangerous because if you accidentally remove the lid or the front part of the case while the rotating brush is rotating, your fingers may come into contact with the rotating brush or cloth etc. may get caught up in it. .

SUMMARY OF THE INVENTION The present invention provides an electric floor suction tool in which the rotating brush is prevented from rotating when the lid of the main body case is removed and the opening above the rotating brush is opened. The goal is to improve safety when cleaning brushes.

[0005]

[Means for Solving the Problems] The present invention has a main body case having a suction port on the bottom surface, in which a rotary brush rotated by a motor is rotatably supported, and a main body case on the upper surface side of the rotary brush. The main body case has an opening that can be opened and closed by a lid, and a switch is provided in the main case to turn off power supply to the motor when the lid is opened.

[0006]

[Operation] When the lid 19 closes the opening 18 during cleaning, the contact piece 22 of the lid 19 contacts the switch 23 and turns on the power supply to the motor 10, so the motor 10 rotates. The brush 12 rotates and scrapes up dust.

When cleaning dust such as lint adhering to the rotating brush 12, if the lid 19 is opened from the opening 18,
The contact piece 22 is separated from the switch 23, and the motor 10
Since the power supply to is turned off, the motor 10 stops and the rotating brush 12 also stops, and in this state, dust such as lint is removed from the rotating brush 12 and cleaning is performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an electric floor suction tool which is an embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

Reference numeral 1 denotes a main body case of an electric floor suction device, which is composed of an upper case 2 and a lower case 3, and has a bumper 4 at the front and a connecting pipe 5 connected to the suction hose of a vacuum cleaner at the rear. is rotatably supported on a shaft, and wheels 6 are installed at the bottom.
It is equipped with A rotating brush storage chamber 8 with a suction port 7 bored in the lower part is provided in the front part of the main body case 1, a power transmission chamber 9 is provided in the side part, and a motor 10 as a rotational drive source is provided in the rear part. The output pulley 11 is connected to the power transmission chamber 9
It is stored so that it protrudes.

Reference numeral 12 denotes a rotating brush, which has a belt pulley section 14 on the side of a brush section 13 having brush bristles, and shaft sections 15, 15 protruding from both ends. The rotating brush 12 has its brush portion 13 stored in the rotating brush storage chamber 8, the belt pulley portion 14 stored in the power transmission chamber 9, and the shaft portions 15, 15 on both left and right sides of the lower case 3. It is pivotally supported on bearings 16, 16 formed on the wall so that it can be moved in and out from above. Also, the output pulley 1 of the motor 10
A belt 17 for transmitting rotational force is suspended between the belt pulley portion 14 and the belt pulley portion 14 .

Reference numeral 18 denotes a U-shaped opening formed in the front part of the upper case 2 of the main body case 1 facing the upper surface side of the rotating brush storage chamber 8, extending to both the left and right sides and extending from both the left and right sides to the rear. The U-shaped lid body 19 covers the U-shaped opening 18 so as to be openable and closable.
(not shown) to cover the U-shaped opening 18 and be attached to the main body case 1. A contact piece 22 extending downward is integrally molded on one side piece 20 of the U-shaped lid 19.

Reference numeral 23 denotes a normally open switch that is attached to the side of the main body case 1 at a location opposite to the abutment piece 22 and turns on and off the power supply to the motor 10. The switch operation piece 24 is connected to the upper case 2 It is exposed upward from the switch opening 25. Then, the U-shaped opening 1 is opened in the lid body 19.
8 is closed, the abutment piece 22 of the U-shaped lid 19 passes through the switch opening 25 to the switch operation piece 24.
The switch 23 is turned on and supplies power to the motor 10 by pressing the switch 23 into contact with the U-shaped lid 19.
is removed from the U-shaped opening 18 to open the U-shaped opening 1.
8 is opened, the contact piece 22 is separated from the switch operation piece 24, the switch 23 is turned off, and the power supply to the motor 10 is turned off.

In the embodiment, the abutment piece 22 is formed on the lid body 19 itself, but in another embodiment, an abutment piece is formed on the clamp body 21 of the lid body 19 and the abutment piece 22 is interlocked with the clamp body 21. The switch 23 may also be operated.

With the above configuration, the U-shaped lid 19 closes the U-shaped opening 18 during cleaning, and the contact piece 22 of the U-shaped lid 19 presses against the switch operation piece 24. , the switch 23 is turned on and power is supplied to the motor 10, the rotating brush 12 rotates and scrapes up dust, and the scraped up dust is sucked into the vacuum cleaner via the connection pipe 5 and the suction hose.

If dust such as lint adheres to the rotating brush 12, the efficiency of scraping up the dust will deteriorate, so the rotating brush 1
2 cleaning is required. When cleaning the rotating brush 12, remove the U-shaped lid 19 from the U-shaped opening 18,
The rotating brush 12 is exposed to the opening 18 or removed from the opening 18 to remove dust such as lint entangled in the brush bristles. During this cleaning, when the lid body 19 is removed from the opening 18, the contact piece 22 is separated from the switch operation 24, so the switch 23 is turned off, and the power supply to the motor 10 is turned off, so that the rotary brush 12 stops rotating. Therefore, during cleaning, there is no risk of fingers, cloth, etc. getting caught in the rotating brush 12, and the rotating brush 12 can be safely cleaned.
can be cleaned.

[0016]

Effects of the Invention The electric floor suction tool of the present invention is constructed as described above. A contact piece is provided to operate the switch that turns on and off the power supply to the rotating brush motor, and when the lid is separated from the opening, the contact piece moves away from the switch and turns off the switch. If you remove the cover when cleaning the rotary brush, the switch will turn off and the rotation of the rotating brush will surely stop, making it possible to safely clean the rotating brush without getting your fingers or cloth caught in the rotating brush. ing.
