Description

[Detailed Description of the Invention] The present invention relates to a carpet cleaning device having a detergent foaming function.

In conventional carpet cleaning devices, the detergent foaming structure includes a sponge roller and a rotating brush in contact with the sponge roller.

However, with this configuration, the rotating brush only contacts the surface of the sponge roller in a stroking manner, and therefore, the contact area is small and a large amount of foam cannot be obtained.

The present invention eliminates these conventional drawbacks and ensures efficient foaming of detergent to ensure carpet cleaning.

In other words, in the present invention, the detergent foaming section is composed of a fixed brush that receives detergent supply from a detergent tank and a rotating brush that rotates in contact with the fixed brush. This is intended to increase the amount of foaming by increasing the contact area.

Examples thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a cleaning device main body with an operating handle 2 connected to the rear thereof, and a rotating brush 3 and a motor 5 for driving the rotating brush 3 via a belt 4 are installed therein.

Incidentally, a part of the bristles 3a of the rotating brush 3 protrude downward through an opening 6 formed in the bottom wall of the cleaning device main body 1.

Reference numeral 7 designates a detergent tank provided above the cleaning device main body 1, from which a detergent guide pipe 8 extends upward from the rotary brush 3 and protrudes from below.

This detergent guide tube 8 has a long hole shape that is elongated in the longitudinal direction of the rotating brush 3.

A fixed brush 9 is held on the inner surface of the opening at the tip of the detergent guide tube 8 via an annular member 10, and its front portion is in contact with the bristles 3a of the rotating brush 3.

In the above configuration, the cleaning operation involves filling the detergent tank 7 with a liquid detergent exclusively for carpets, and energizing the motor 5 to rotate the rotary brush 3 while moving the cleaning device main body 1 back and forth on the carpet.

At this time, the liquid detergent in the detergent tank 7 is first supplied in an optimum amount to the fixed brush 9 via the detergent guide pipe 8, and is held between the bristles 9a.

Since the bristles 3a of the rotating brush 3 are in contact with the bristles 9a of the fixed brush 9 in an intertwined manner,
The liquid detergent held between the bristles 9a is foamed here, and then this foamed detergent is carried to the carpet surface by the rotating brush 3 and rubbed.

The detergent foam then remains on the carpet, surrounding dirt adhering to the surface of the carpet pile and dirt penetrating into the inside of the pile.

Therefore, after the carpet dries, the detergent that has become powder surrounding the dirt can be sucked up with the suction power of a vacuum cleaner, and the pet will come back to life beautifully.

In the above embodiment, the length of the rotating brush was taken care of by making the detergent guide tube in the shape of a long hole. May be installed consecutively.

In this way, the present invention has a three-dimensional contact between the bristles of the fixed brush and the rotating brush, as if intertwined, so the contact area is wide and the detergent held between the bristles of the fixed brush can be efficiently removed. It can be foamed.

Therefore, sufficient foaming detergent necessary for cleaning the carpet can be obtained, and the same cleaning can be performed reliably.

Furthermore, in the case of the present invention, since the detergent is guided to the fixed brush through the guide tube, the detergent can be reliably supplied to the fixed brush even if the main body is tilted a little, and its practical value is extremely large.
