Description

[Detailed description of the invention] Industrial application field The present invention relates to a small rotating brush type cleaning machine for cleaning floors, stairs, walls, etc., and is particularly applicable to difficult-to-clean areas such as corners, uneven parts, and curved surfaces. The present invention relates to a small rotating brush type washer for the purpose of cleaning.

BACKGROUND ART Conventionally, scrubbing brushes, rags, mops, etc. have been frequently used as cleaning tools for cleaning floors, walls, etc. However, as buildings have become taller in recent years, cleaning operations have been required to be streamlined, and various cleaning machines have been developed and put into practical use. In particular, in order to improve the efficiency of cleaning work, a so-called drill-type cleaning machine, which is made up of an electric drill with a brush attached to the tip, has been developed and put on the market. This drill type washer is
An electric drill originally intended for drilling and polishing,
Since it is a tool such as an electric polisher with a cleaning brush attached, it rotates quickly and has low torque, so there are problems such as splashing, and there are also those that are continuously variable when changing the voltage, etc. Furthermore, there were other problems such as lowering the rotational speed and lowering the torque. On the other hand, in order to solve these problems,
Since the main body of the cleaning machine is larger and the brush is fixed, it is good for cleaning obstacles and flat floors, but it is inconvenient when cleaning small rooms, stairs, and interior exterior walls. In addition to being inconvenient, cleaning itself was sometimes difficult.

Problems to be solved by the invention The problems to be solved by the invention lie in solving the disadvantages and inconveniences of conventional methods. In other words, the problem that this invention aims to solve is to make the washing machine smaller so that it can be used not only in general households but also for cleaning services, and to make it usable in small spaces such as small rooms and stairs. In order to do this, the rotating brush should be able to swing and rotate freely, and a simple member should be used for swinging and rotating the rotating brush, and it should be able to be attached and detached freely.

Means for Solving the Problems The present invention was developed to solve the above problems, and consists of a washing machine base with a small handle attached to a drive device for swinging a rotating brush. In a small-sized washing machine, the swinging means of the rotating brush is made of a hard synthetic resin material with elasticity, and the material is integrally molded into a ring shape with two stages, upper and lower, symmetrical to each other, and a driving device is further installed on the upper and lower rings. A brush swinging member is provided with a coupling device for connecting a drive shaft for the rotary brush and a rotary plate for the rotating brush, and the brush swinging member is installed between the drive shaft and the rotary plate in a rotatable and swingable state. All of these problems can be solved by using a rotating brush type small-sized washer. That is, the means for solving the problems of the present invention is to attach a member formed by molding a resilient and hard synthetic resin between the drive shaft that rotates the brush and the rotating brush, and to The point is that it can be put on and taken off freely.

Effects According to the present invention, the member attached between the drive shaft and the rotating brush is made of an elastic material and is molded to be able to swing freely, so that the drive shaft cannot be operated. When the rotating brush is pushed in from above, the attached member is pressed and becomes rocking (squiggly). In other words, the direction and position of the rotating brush can be freely swung through the mounting member.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a conventional rotary brush type small washer improved by the present invention. In the figure, 1 is a rotary plate that rotates the brush 2. Reference numeral 3 denotes a drive device in which a drive shaft 4 is installed, and the tip thereof is shaped so that the rotary plate 1 can be tightened with a bolt 5. That is, the rotary plate 1 can be attached to and detached from the drive shaft 4 of the drive device 3 via the bolts 5. 7 is a washing machine base for attaching the drive device 3 to the motor 8, and 6 is a set screw thereof. 9 is a holder for attaching the cord 12 to the washing machine base 7, and 10 is a switch. A spring 11 is provided between the holder 9 and the handle 13 for resiliently attaching the cord 12. 14 is another handle of handle 13.

As is clear from this figure, in this conventional rotary brush type small-sized washing machine, the rotary plate 1 for rotating the brush 2 is fixed directly and perpendicularly to the drive shaft 4, so the rotary plate 1 with the brush 2 is It is always perpendicular to the drive shaft 4. Therefore, the handle 13,
When the rotary plate 1 is rotated via the rotary plate 14, the brush 2 always rotates perpendicular to the drive shaft 4.

FIG. 2 shows a rotating brush type small-sized washer according to the present invention, and 21 is a brush swinging member which is an important part of the present invention. The brush swinging member 21 is made of elastic and hard synthetic resin such as rubber, and this material is molded into a ring shape with two stages, upper and lower, and symmetrical to each other, as shown in this figure.
Reference numeral 22 denotes a drive shaft coupling device fixed to the center of the upper ring of the brush swinging member 21, while 23 is a rotating plate coupling device fixed to the center of the lower ring.
A threaded portion is formed at the tip of the rotary plate connecting tool 23 so that the bolt 5 can be screwed into the tip. 24 is a set screw for fixing the drive shaft coupling tool 22 and the rotating plate coupling tool 23. The reason why this brush swinging member 21 is molded into such a shape is to provide elasticity between the drive shaft 4 of the drive device 3 and the rotary plate 1, and to suppress the force applied to the drive shaft 4. This is to ensure that the pressure is applied evenly and in any direction.

Next, a method for attaching and detaching the brush swinging member 21 will be explained. First, as shown in FIG.
The rotating plate 1 and the drive device 3 are separated from each other. Next, the drive shaft coupling tool 22 of the brush swinging member 21 is inserted into the lower end of the drive shaft 4 via the set screw 24, and the rotating plate coupling tool 23 is also connected to the rotating plate via the bolt 5. Screw on 1. That is, the brush swinging member 21 is fixed between the drive device 3 and the rotating brush portion via the drive shaft interlocking tool 22 and the rotary plate interlocking tool 23. Note that the washing machine base 7 and the drive device 3 are attached via a set screw 6 as in the conventional manner.

FIG. 3 shows the characteristics of the brush swinging member 21, which is the main part of the present invention. Figure A shows a state in which the brush swinging member 21 is set as shown in Figure 2. As is clear from this figure, when the drive shaft 4 is in the vertical position, the entire weight of the washer is applied to the drive shaft coupling device 22 of the brush swinging member 21, and the force is distributed to both sides of the upper ring. The rotating plate connecting tool 2 is distributed on both sides of the lower ring.
It will be gathered at 3. Therefore, the brush swinging member 21 is almost in its original shape, although the upper ring portion is slightly pressed.

Figures B and C show the case where the drive shaft 4 is pressurized (the drive device 3 is pressed through the handles 13 and 14), with B being pressurized in the vertical direction and C being pressurized in the inclined direction, respectively. This shows the case where When pressure is applied in the vertical direction, the upper ring and the lower ring are pushed from above as shown in FIG. 2, so that the brush swinging member 21 is pushed laterally.
On the other hand, when pressure is applied in the oblique direction, the upper ring and the lower ring are pressed in a deformed state because they are pushed from the diagonal direction as shown in Figure C. Therefore, by freely applying pressure in the vertical direction and the oblique direction, the brush swinging member 21 can take on a shape that can change freely, and accordingly, the rotary plate 1 can also be freely rocked. Since the rotary plate 1 is swingable, the brush 2 can also be swing-rotated.

The present invention provides a small-sized washing machine in which a driving device for swinging a rotating brush is attached to a washing machine base with a small handle, and the swinging means for the rotating brush is made of a hard synthetic resin material having elasticity. , the material is integrally molded into a ring shape with upper and lower stages and mutually symmetrical, and further a brush swinging member is provided on the upper and lower rings with a connecting device for connecting a drive shaft for a drive device and a rotary plate for a rotating brush, Since the brush swinging member is installed between the drive shaft and the rotary plate in a rotatable and swingable state, the swinging action is better than that of a conventional swing-type rotary brush. Not only that, but the swinging member can be attached and detached freely. Therefore,
You can freely clean any place that was previously considered impossible or difficult, such as the corner of a room or a narrow space.

Furthermore, since the swinging member according to the present invention has a simple structure and uses inexpensive materials, it is not only easy to mold, but also mass-produced at low cost. Furthermore, since it is easy to attach and detach, by using the member of the present invention, it is possible to provide a small rotary brush type washing machine that is not only economical but also excellent in practicality.
