Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric floor polisher, and its purpose is to provide a convenient electric floor polisher that can spray a foamy detergent onto the surface of an object to be cleaned, such as a carpet. It is intended to provide a floor polisher, with special consideration given to the brush stand that the foaming brush comes into contact with.
The purpose is to improve foaming performance.

Conventionally, as shown in FIG. 1, an annular groove 101 is located on the inner circumference of a brush stand 100 and is open upward.
The foaming tool and the protrusion 102 are in contact with each other, and the detergent liquid flowing out from the detergent tank is foamed by the relative movement between the foaming tool and the protrusion. Since the foaming tool simply goes over the protrusion 102 of the brush stand, the foaming performance of the cleaning solution is poor, and if too much cleaning solution is dispensed, it may cause stains on the jacket, or it may cause damp foam. There was a problem that it took a long time to dry because only the paper could be removed.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the accompanying drawings.

In Figures 2 to 7, 1 is a cleaning main body with an operating handle 2 protruding upward, a base 3 and a cover 4.
and constitute the base. 5 is a motor installed in the space between the base 3 and cover 4 via a mounting body 6; 7 is rotatably supported by the base 3 and connected to a geared shaft 8 of the motor 5 via a plurality of reduction gears 9;
The outer periphery of the brush drive shaft that protrudes downward from the base 3 has a polygonal shape, and a metal piece 11 integrally formed with the brush stand 10 fits into it to accurately transmit rotational force. I have to. Furthermore, claw-shaped protrusions 12 are formed near the lower end of this shaft hole to prevent the brush stand 10 from coming off. 13 is a plurality of protrusions formed on the inner bottom surface of the annular groove 14 in the brush stand 10;
They are roughly diamond-shaped and are connected to each other. Numeral 15 is a plurality of detergent flow holes formed on the outer periphery of the inner bottom surface of the groove 14, and 16 is a foaming tool, with a brush 16a installed at the lower end and a stopper protrusion 16b formed at the upper end. This foaming tool 16 is the groove 1 of the brush stand 10.
4, and its brush 16a is located at the brush stand 1.
A substantially diamond-shaped protrusion 13 is in contact with the bottom surface of the groove 14 of 0.
It can be widened or narrowed. Also, the stopper protrusion 16b is the protrusion 1 on the lower surface of the base 3.
7 prevents rotational movement, the brush stand 10 and the foaming tool 16 do not rotate together, and the groove 1
Perform relative movement within 4. 18 is brush stand 1
The brush 19 installed on the lower surface of the brush 1 is a tank for storing a detergent solution, and the detergent solution therein is communicated to the main body through a pipe 20 by opening and closing a valve (not shown).

In the above structure, since the approximately diamond-shaped protrusions 13 are continuously formed at the bottom of the groove 14 of the brush stand 10, the brush 16a of the foaming tool 16 does not widen or narrow as shown in FIGS. The brush 16a repeatedly climbs over the protrusion 13 and sends a large amount of air into the liquid due to the so-called breathing action of the brush 16a, which results in good foaming. Because it makes delicate movements,
A large amount of fine, high-quality foam is obtained, and the brush stand 1
The detergent passes through the detergent flow hole 15 provided on the outer periphery of the inner bottom of the groove 14 and is applied onto the carpet. Therefore,
When applied to the carpet, it forms fine bubbles, so even if you apply too much, it won't stain the carpet, and it can dry faster.

As described above, according to the present invention, the foaming properties of the detergent are very good, and the detergent can be cleaned accurately, and the effect is extremely large.

Claims (1)

[Claims] 1 A brush stand that has a cleaning brush on the bottom surface and an annular groove for receiving detergent liquid on the top surface, and has a brush stand rotated by a motor and a foaming brush that plunges into the groove. The brush stand has a detergent flow hole at the bottom of the groove, and a roughly diamond-shaped foaming tool that continuously expands and deflates the foaming brush. A foaming device for an electric floor polisher, characterized in that a protrusion having a guide wall portion is formed respectively.
