Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floor nozzle for a vacuum cleaner with rotating brushes driven by a turbine.

Conventional configuration and its problems Conventionally, in the floor nozzle of this type of vacuum cleaner, the rotation of the turbine rotated by suction air is transmitted to the rotating bluff via a belt etc., but the rotating brush scrapes up dust. To do this, a large amount of torque is required, so the torque of the turbine that makes it rotate completely must also be increased. Therefore,
The air passage around the turbine is set narrow so that the suction air impinges on the turbine at high speed. However, dust tends to accumulate around the turbine, and when foreign objects such as glass fragments and pebbles are sucked in, the turbine may get caught in the foreign objects and the rotation may become slow. Conventionally, in such cases, it was necessary to disassemble the floor nozzle body and remove the foreign matter, making maintenance difficult.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned problems, and makes it possible to clean the turbine section with a single touch, thereby facilitating the removal work when foreign matter is caught in the turbine.

Structure of the Invention The present invention includes a connecting body rotatably provided in a turbine chamber, and a turbine rotatably attached to the connecting body, and the turbine and the connecting body are attached to and detached from the turbine chamber. This makes it easier to remove foreign objects caught in the turbine, making turbine maintenance easier.

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

1 and 3, reference numeral 1 denotes a floor nozzle body, which is divided into a suction chamber 3 containing a rotating brush 2 and a turbine chamber 6 containing a turbine 4 by a wall 6. The rotating brush 2 is rotatably attached to the suction chamber 3 and positioned so that its bristles 7 protrude from the suction port 8. Reference numeral 9 denotes a connecting body rotatably and removably provided in the turbine chamber 6, which is supported by the slider 10 and rotates along the slider 10 and the inner wall of the turbine chamber 6. It is rotatable.

Reference numeral 11 denotes a connecting pipe provided in the connecting body, which communicates with the turbine chamber.

The turbine rotates in the turbine chamber 6 by rotatably supporting the shaft 13 on the connecting body 9 .

A clutch plate 14 is provided at the tip of the shaft 13, and a sliding clutch plate 17 is provided on the turbine chamber side of the clutch shaft 16, which is rotatably attached to a bearing 16 fixed to the floor nozzle body 1. Connected detachably. 18 is a spring that biases the sliding clutch plate 16.

The outer peripheral end surfaces of the latch plate 14 and the sliding clutch plate 16 are inclined at 4C so that they can be easily connected when the connecting body 9 is inserted.

Reference numeral 19 denotes a belt stretched between the clutch shaft 16 and a boolean IJ-20 formed integrally with the rotating brush 2.
7 → clutch shaft 16 → belt 19 → transmitted to rotating brush 2 via pulley 20i.

Reference numerals 21 and 22 designate small communication ports and large communication ports provided in the wall 6 at positions facing the turbine 4 and at positions not facing the turbine 4, and the large communication port 2
2 is opened and closed by a lid 24 formed integrally with the switching lever 23.

In the above configuration, when cleaning a carpet or the like, the switching lever 23 is operated to close the large communication port 22 with the lid 24. Then, the suction air entering from the suction port 8 enters the turbine chamber 5 through the small communication port 21 and collides with the turbine 4. After the turbine 4 is rotated, the connection pipe 17 is passed through the extension pipe, then the hose, and then the vacuum cleaner body.

Tahif 40 rotations is the above-mentioned clutch mechanism and belt 19
The dust is transmitted to the rotating brush 2 via the rotary brush 2, and as the rotating brush 2 rotates, it scrapes up lint and the like from the carpet and exhibits excellent dust collection performance.

When cleaning the floor, tatami mats, etc., the large communication port 22 is opened. Then, most of the suction air enters the turbine chamber 6 through the large communication port 22, passes through the connecting pipe 11 without colliding with the turbine 4, and reaches the cleaner body.

At that time, some suction air enters the turbine chamber 6 from the two small communication ports, but since the amount is small, even if it collides with the turbine 4, it will not be able to rotate it, so the rotating brush 2 that is linked to the turbine 4 will also not be able to rotate. Does not rotate.

Therefore, floors, tatami mats, etc. can be cleaned without damaging them by the rotation of the rotary brush 2. Incidentally, there is no need to rotate the rotary brush 2 since the dust on the floor and the folding surface can be sufficiently captured by the suction force alone.

Nowadays, when cleaning a carpet, etc., the turbine 4 and rotating brush 2 are rotated to clean it, but what about foreign objects such as broken glass or pebbles? If they are inhaled, the turbine 4 may get caught in the foreign matter and stop rotating.

In the conventional example, in this case, the floor nozzle body 1 is disassembled,
However, in the present invention, the turbine chamber 6 is opened by sliding the slider 10' (il-) and removing the connecting body 9 to which the turbine 4 is attached, so that the foreign matter can be easily removed. You can also clean the turbine 4 with a brush or the like while the connecting pipe 11 is connected to a running vacuum cleaner, and the fine dust attached to the turbine 4 will be sucked into the connecting pipe 11 and will not be scattered around. Can be cleaned.

Also when attaching the connection body 9 to the turbine chamber 5, the pin 4
By engaging the clutch plate 14 with the sliding clutch plate 17, it is possible to easily transmit the rotation of the turbine 4 to the rotating brush 2, and this can be done with a simple operation.

Effects of the Invention As described above, the present invention removably supports the connection body rotatably provided in the turbine chamber, and also configures the turbine to be detachable, so that the entire turbine is rotatably attached to the connection body. Since the turbine can be installed and removed from the turbine chamber at the same time, if the turbine gets stuck with foreign objects such as broken glass or pebbles, the foreign objects can be removed manually by removing the turbine and the connecting body. In addition, if you clean the turbine attached to the connection body with a brush while the connection body is connected to a running vacuum cleaner, the suction power of the vacuum cleaner will cause the dust that sticks to the turbine and scatter around it. It has excellent effects such as being able to clean the turbine without having to clean it.
