Description

[Detailed description of the invention] This invention uses a rotating brush driven by an air turbine or electric motor that is rotated by the intake air of a vacuum cleaner, and the detergent supplied onto the rotating brush part or the carpet is rubbed onto the carpet while brushing. The purpose of this product is to allow the connecting pipe to connect to the extension pipe of a vacuum cleaner to rotate as much as necessary for operation when cleaning, and to restrict rotation when moving or lifting. do.

Conventionally, in carpet cleaning tools, the connecting pipe for connecting to the extension pipe of a vacuum cleaner is rotatably fixed to the body of the cleaning tool so that it can slide in any direction. Since the container is mounted on the upper side of the machine and the detergent is supplied to the rotating brush section, etc., the weight of the detergent and the detergent container causes the center of gravity of the machine to be above the center of rotation of the connecting pipe. When the machine was lifted by the extension tube during transportation, the machine turned upside down, causing problems such as detergent flowing out from the detergent container.

The present invention aims to solve the above problem, and embodiments thereof will be described below based on the drawings.

In the figure, 1 is a cleaning tool main body, 2 is an air turbine driven by the suction airflow of a vacuum cleaner, and is housed in a turbine chamber 3.

Reference numeral 4 denotes a rotating brush, which is installed with a brush and is rotated in conjunction with the air turbine 2 by a belt 5.

Reference numeral 6 denotes an intake port that takes in air for rotating the air turbine 2.

7 is a detergent tank, which is mounted on the upper side of the cleaning tool main body 1, supplies detergent onto the fixed brush 9 from the detergent dripping port 8, foams the detergent by the rotating contact of the rotating brush 4, and rubs it onto the carpet. go.

Reference numeral 10 denotes a connecting pipe, which fits into an extension pipe 11 of a vacuum cleaner, communicates the other end with the turbine chamber 3, and is rotatably prevented from being removed by a ring 12.

Reference numeral 13 denotes a collar portion provided on the connecting pipe 10, which has a protrusion 16 facing the end surface 15 of the pipe insertion hole 14 of the main body 1.

Reference numeral 17 indicates a notch partially provided in the end surface 15.

The protrusion 16 is normally located outside the end face 15 to regulate the insertion depth of the connecting pipe 10, and is provided at a position exactly opposite to the bending direction of the connecting pipe 10.

The notch 17 is provided in a part of the lower part of the end surface 15.

A gap 18 for rotation of the connecting pipe 10 is provided at the fitting portion between the pipe insertion hole 14 and the connecting pipe 10.

In the above configuration, when the connecting pipe 10 is fitted into the extension pipe 11 and operated by connecting it to a vacuum cleaner, air enters the turbine chamber 3 through the intake port 6 due to the suction of the vacuum cleaner, causing the air turbine 4 and the rotation. The brush rotates to lather the detergent supplied to the fixed brush 9 and rub it onto the carpet to clean it.

During this cleaning, the rotating brush 4 is pressed onto the carpet, so the extension tube 11 naturally tends to fall toward the cleaning tool main body 1 using the connecting pipe 10 as a fulcrum, and since there is a gap 18, the protrusion 16 moves away from the end surface 15. Therefore, the connecting pipe 10 can be freely rotated with respect to the main body 1 and can be cleaned without impairing usability.

On the other hand, when lifting the extension tube 11 during movement, the main body 1 tilts in the direction of gravity due to the weight of the main body 1, and therefore the notch 17
coincides with the protrusion 16, the rotation of the main body 1 and the connecting pipe 10 is limited to an angle θ, and it is possible to prevent the main body 1 from being reversed.

As described above, according to the present invention, when cleaning a carpet, the connecting pipe becomes free with respect to the main body of the cleaning tool, so cleaning work efficiency is significantly improved, and when the main body of the cleaning tool is lifted, it only tilts at a certain angle. Because of this, accidents such as detergent spills can be prevented.
