Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floor nozzle for a vacuum cleaner having a rotating brush and a turbine for rotating the rotating brush.

Conventional Structure and Problems Conventionally, in this type of floor nozzle, the rotary brush stirs up dust from the surface to be cleaned, so the turbine that rotates the rotary brush requires strong output. For this reason, the air passage at the bottom of the turbine was set narrow to increase the speed of the air that collided with the turbine.However, because the air passage at the bottom of the turbine was narrow, foreign objects such as pebbles and glass fragments were trapped there. In some cases, the turbine would lock up and stop rotating. Conventionally, in this case, the floor nozzle main body had to be disassembled to remove the foreign matter, which was difficult to remove.

OBJECTS OF THE INVENTION The present invention solves the above problems by making the turbine chamber freely openable and closable, and making it possible to remove foreign matter trapped by the turbine with a single touch.

Composition of the Invention The present invention provides a floor nozzle that has a suction port in which a rotating brush is installed in the front, and a rear-open, generally semi-cylindrical turbine chamber in which a turbine serving as a drive source for the rotating brush is installed in the rear. a main body, a connecting pipe having a substantially semi-cylindrical connecting body that is removably and rotatably fitted into the turbine chamber, and a rear outer periphery of the connecting body to prevent the connecting body from falling off from the turbine chamber. It is equipped with a lid that is fitted into the lid and is slidable laterally.

Therefore, even if a foreign object gets caught in the turbine, the rear part of the turbine chamber can be opened by sliding the lid and removing the connection body.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 to 5, reference numeral 1 denotes a floor nozzle body, and a bumper 4 is held between upper and lower members 2 and 3. Reference numeral 5 denotes a rotating brush rotatably provided in the suction chamber 6, and its bristles 7 are made to protrude from the suction port 8. A turbine 9 is installed in the turbine chamber 10 and has a shaft 11 that projects laterally and is supported by a shaft support 12 of the main body 1 .

The rotation of the turbine 9 is caused by a shaft 1 protruding from the turbine 9.
1 and a pulley 13 provided at one end of the rotating brush 5.

A connecting body 16 having a connecting pipe 15 is rotatably mounted in the turbine chamber 10 . That is, the turbine chamber 10 and the connecting body 16 are formed into semi-cylindrical shapes that fit into each other.

Furthermore, the connecting body 16 is connected to the opening 17 of the turbine chamber 10.
The main body 1 is normally rotatably attached to the main body 1 by means of lids 18 which are slidably provided on both sides of the opening 17.

19 is a small communication port provided at a position facing the turbine 9, 20 is a large communication port provided at a position not opposed to the turbine 9, and the large communication port 20 is connected to the switching lever 21.
It is opened and closed by

In the above configuration, when cleaning the floor folding etc., the switching lever 21 is operated to open the large communication port 20. In this case, most of the suction air flows through the large communication port 20, so that less air collides with the turbine 9, and the turbine 9 and the rotating brush 5 do not rotate. Therefore, it is possible to clean the floor tatami without damaging it.

When cleaning a bathtub, etc., use the switching lever 21.
to close the Dairen communication port 20. In that case,
The suction air enters through the small communication port 19, collides with the turbine 9, and rotates the turbine 9. The rotation of the turbine 9 is transmitted to the rotating brush 5 via the belt 14 and the pulley 13, and the rotation of the rotating brush 5 scrapes up lint and the like attached to the carpet, allowing efficient cleaning. .

When you inhale pebbles or broken glass,
The turbine 9 gets caught in these foreign objects and stops rotating.

Conventionally, in this case, the floor nozzle body had to be disassembled to remove the foreign matter, which was extremely time-consuming.

In the present invention, when the turbine 9 gets caught in a foreign object, the lid 18 is slid, the connecting body 16 is removed from the turbine chamber 10, and the turbine chamber 10 is opened.
Thereby, the inside of the turbine chamber 10 can be easily cleaned, and the work of removing foreign matter caught in the turbine 9 can be easily performed.

When the connection body 16 is pushed into the turbine chamber 10, the connection etc. 16 is rotatably connected, so that the floor nozzle body 1 and the connection etc. can be raised and raised freely, and normal cleaning work can be performed easily.

Effects of the Invention As described above, in the present invention, since the connecting body with the connecting pipe communicating with the turbine chamber is rotatably provided and detachably formed, the turbine chamber can be opened with a single touch, and the turbine can be inserted into the turbine chamber. Foreign matter can be easily removed.

Furthermore, when the connecting body is installed in the turbine room, the connecting body can rotate freely, so the floor nozzle body and the connecting pipe can be moved up and down, making it easy to carry out regular cleaning work. It is something that demonstrates the.
