Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the structure of an electric floor suction device that is connected to a vacuum cleaner via a hose and an extension tube.

2. Description of the Related Art Conventional electric floor suction tools (hereinafter referred to as suction tools) generally have a structure as shown in Japanese Utility Model Publication No. 10594/1983.

The configuration will be explained below based on the drawings.

In FIG. 5, the suction device main body 1 has a rotating brush 2ft in the front part and a built-in rotating brush chamber 3? : At the rear thereof, a connecting pipe 4 communicating with a motor 4 as a rotating brush drive source and a rotating brush chamber 3 is provided.

Reference numeral 6 indicates bearings disposed at both ends of the rotating brush 2, and reference numeral 6 indicates a belt installed between the rotating 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.

Note that the suction tool 1 is formed of upper and lower body members.

Problems to be Solved by the Invention However, such a suction tool has a structure in which a bearing 6 etc. is arranged at the end of the rotating brush 2 and is covered with an upper body member and a lower body member, and the end of the suction tool body 1 is It was not possible to arrange the rotating brush 2 up to that point. Therefore, it is not possible to clean up to the ends of the suction device main body 1, and there is a problem in that dust remains, especially when cleaning the corners of a room.

The present invention solves the above-mentioned conventional drawbacks, and includes an auxiliary brush disposed at the end of a rotating brush, and slanted bristles are implanted in the end of the rotating brush and the auxiliary brush. Remove any remaining dirt from the end of the bearing and the bearing holder, or
To provide an electric floor suction tool that can perform reliable cleaning with a small amount of use.

Means for Solving the Problems In order to solve the above conventional problems, the present invention consists of a rotating brush consisting of a main brush and an auxiliary brush, the auxiliary brush is arranged at the end of the main brush, and the main brush is The bristles at the end are planted at an angle toward the end of the suction tool body, and the bristles of the auxiliary brush are planted at an angle alternately toward the end and inside of the suction tool main body. .

According to the above-mentioned invention, the auxiliary brush rotates in conjunction with the main brush, and the bearing holding portion overlaps with the main brush and tilts so that the ends of the suction tool main body are The bristles on the auxiliary brush are tilted outward to scrape up dirt from the floor, making it difficult to leave dirt behind, and making it possible to reliably clean even the corners of the room.

EXAMPLE Hereinafter, an example of the present invention will be explained with reference to FIGS. 1 to 4.

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

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

The suction device main body 13 has a rotating brush chamber 18 containing a rotating brush 17 in its front part, and a motor 19 on one side of its rear part.
Motor chamber 2o with built-in motor 19 is placed on the opposite side.
21. Each has a circuit chamber 25 equipped with a printed circuit board 24 incorporating electric components such as a positive characteristic thermistor 221, ignition 9, and a current fuse 23 for preventing smoke generation.
In the center of the rear part is an intake passage 2 that communicates with the rotating brush chamber 1B.
6 and the connecting pipe 14'ii are provided.

Reference numeral 27 denotes a suction port arranged at the lower part of the rotating brush chamber 18, through which the rotating brush 17 is exposed to the floor surface.

The suction device main body 13 has an upper main body member 28. Lower body member 29. The brush cover 30 forms an outer shell to form each of the above-mentioned rooms. 31 is a rotating brush 17 and a motor 19
A belt installed between them transmits 190 rotations of the motor to the rotating brush 17.

The rotating brush 17 is the main brush 32. It is composed of an auxiliary brush 33, a bearing 34, etc., and 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 part 35 of the brush cover 30. Ru.

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 opposite to the auxiliary brush 33.

Said auxiliary brush 33. Hair 36 is implanted on the outer periphery of the main brush 32, a bearing 34 rotatably supports a shaft 37 inserted into the main brush 32, and an auxiliary brush 33 is attached to the end of the shaft 37.
is inserted and fixed.

The auxiliary brush 33 has bristles 36 installed at an angle, and the bristles 36 are sucked into the lower body member 29 and the brush cover 30 by looking outward from the side end open chamber 38 with the (li end) open. The auxiliary brush 3 is placed at the very edge of the tool body 13 to ensure cleaning even the corners of the room.
The rigid body part 3 does not protrude from the side of the suction device main body 13, making it easy to use.

We ensure that safety is not compromised.

Reference numeral 39 denotes a bypass passage arranged at the rear upper part of the bearing holding part 35, which communicates the rotating brush chamber 18 with the side end open chamber 38 and guides the dirt scraped up by the auxiliary brush 33 to the rotating brush chamber 18. ing.

Further, the bristles 36 at the end of the main brush 32 are attached to the suction tool main body 1.
The bristles 36 of the auxiliary brush 33 are attached to the outer periphery of the suction device main body 13.
A plurality of plants are planted on the end side of the side end open chamber 38, that is, on the outside of the side end open chamber 38 and the inside of the bearing holding part 35 side, and are tilted to each other, so that they are connected to the floor surface under the bearing holding part 35 and the suction. The floor surface below the end of the tool body 13 can be cleaned.

In particular, the hairs 36 planted at an angle are set longer than the hairs in other parts, and spread further outward when they come into contact with the floor surface9.
, the bottom of the bearing holding part 36 and the side edges of the suction tool 13 can be reliably cleaned.

Effects of the Invention As described above, the present invention consists of a rotating brush consisting of a main brush and an auxiliary brush, the auxiliary brush is arranged at the end of the main brush via a bearing, and the bristles of each brush are arranged under the bearing holding part. The electric floor is installed at an angle so as to reach the end of the suction tool body, so it can reliably clean the end of the suction tool without leaving any dirt behind.It is an electric floor that can efficiently clean even the corners of the room. It is possible to provide a suction device for
