Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a carpet cleaning nozzle, and an object of the present invention is to easily remove stains from a carpet and refresh the carpet using an aerosol detergent for carpets.

Conventionally, carpet cleaning nozzles use liquid detergent, and a fixed brush is placed in contact with a rotating brush driven by an air turbine, and the liquid detergent is dripped onto the fixed brush to form foam. had been developed, but the foaming effect was not necessarily satisfactory under load fluctuations such as the type of carpet.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 1 to 3.

In Figures 1 to 3, 1 is a nozzle main body, 2 is a rotating brush chamber, 3 is an air turbine chamber, 4 is a rotating brush housed in the rotating brush chamber 2 and has brushes installed in a spiral shape, and 5 is an air turbine chamber. The air turbine is housed in the air turbine 3 and is driven by the intake air flow shown by the arrow in FIG.

6 is a belt for transmitting the rotation of the air turbine 5 to the rotary brush 4; 7 is an aerosol detergent fixing frame having an aerosol detergent fixing projection 8 made of an elastic material.

Reference numeral 9 denotes a detergent tank presser body which is provided to press the detergent spouting part 11 of the aerosol detergent tank 10 and is made of an elastic material and has a detergent port 12; A fixed brush 13a is provided at the lower end of the front wall 1a so as to be in contact with the floor surface.

In the above configuration, when the nozzle body 1 is connected to a vacuum cleaner, the intake air flows as shown by the arrow in FIG.
Rotate.

Then, the rotational force is transmitted to the rotating brush 4 by the belt 6, and the rotating brush 4 also starts rotating at the same time.

When the aerosol detergent tank 10 is inserted into the aerosol detergent fixing frame 7, the detergent jetting part 11 is pressed by the detergent tank presser 9, and the foamed detergent is released from the detergent tank presser 9.
The detergent passes through the detergent port 12 and exits from the detergent passage 13 onto the carpet.

Here, the aerosol detergent fixing protrusion 8 plays a role in fixing the aerosol detergent tank 10.

When the nozzle body 1 is operated on the carpet in this way, the fixed brush 13 applies the detergent that has come out onto the carpet onto the carpet surface, and the rotating brush 4 further brushes the detergent-containing carpet surface.

Once the carpet that has been strained and washed in this way is dried,
The detergent that envelops the dirt becomes powder and remains on the carpet cleaner, so if you vacuum it up with a vacuum cleaner, your carpet will be beautifully refreshed.

Here, the role of the fixed brush 13 is not only to simply apply detergent to the carpet, but also to guide the supplied detergent into the rotating brush chamber 2 and to prevent the detergent from flowing into the rotating brush 4 so as not to apply a load due to the viscosity of the detergent. It also has a preventive effect.

As described above, according to the present invention, the carpet can be easily washed using the fixed brush that applies the detergent to the carpet using an aerosol detergent, and the rotating brush that performs cleaning (brushing). The effect is extremely impressive, as there is no reduction in rotation.

Claims (1)

[Claims] 1. A nozzle body, an air turbine arranged inside the air turbine chamber and rotated by suction airflow, a rotating brush that rotates in conjunction with the air turbine, and a detergent tank fixing frame to which an aerosol detergent tank can be detachably attached. A detergent passage is formed in the front wall of the rotating brush chamber of the nozzle main body, and is separated from the rotating brush chamber for causing the ejected detergent to flow downward along the front wall, and the front wall A carpet cleaning nozzle is provided with a fixed brush in contact with the floor at the lower end of the nozzle, and the suction airflow path is configured to pass through a part other than the rotating brush chamber.
