Hereinafter, an operation process of the conventional inhaler (100) will be described with reference to FIGS.

First, when an operator applies power to the main body (300) and turns on a power switch, a motor (not shown) installed in the main body (300) rotates at a high speed. External air is drawn into the suction device (100) and the communication member (200) by the rotation force of the motor.
Through the body (300).

At this time, the turbine (50) installed in the suction means (100) is, as shown in FIG.
The rotating brush (60) connected to the turbine (50) via a belt (70) is rotated at a high speed by the intake air sucked into the connecting pipe (130).
The motor rotates synchronously due to the rotational force of.

Therefore, when the operator grips the handle adjusting portion (230) shown in FIG. 3 and positions the suction device (100) at the cleaning portion, dust and foreign matter in the cleaning portion are removed by the rotating brush (60). As a result, the gas is removed from the cleaning site, and is sucked into the main body (300) through the connecting pipe (130) and the communication member (200) together with the intake air.

The dust and foreign matter sucked into the main body (300) are collected by the dust collecting pack through the filter, and the cleaning can be completed by the operator's selection.

Adjustment lever (80).

That is, the concave groove (11) of the upper cover (10)
When the handle (82) of the adjusting lever (80) protruding to the right and left is moved in the left-right direction, a shutter (81) integrally formed with the adjusting lever (80) opens and closes an air suction passage, and the connecting pipe is opened. The amount of air taken into (130) can be adjusted.

[0016]

According to the conventional suction device constructed as described above, the installation projection formed only on one side of the turbine connects the first partition member and the second partition member. Along with being installed to cross in the horizontal direction,
Since the turbine is installed in the air intake passage pipe connected to the connecting pipe, not only does the turbine reduce the suction efficiency at the time of sucking dust and foreign matter, but also when the strong suction force is generated, the turbine vibrates. There has been a problem that a large amount of noise is generated due to the phenomenon.

That is, as shown in FIG. 5, when the turbine is installed between the air intake passages connected to the connecting pipe and the partition of the adjusting lever is completely opened, the opening of the lower cover is opened. Most of the dust and foreign matter flowing through the part are moved in the illustrated arrow K direction and sucked into the connection pipe regardless of the installation state of the turbine.
If the partition of the adjusting lever is not completely opened, most of the dust and foreign matter flowing through the opening of the lower cover is caught by the turbine and is not moved in the direction indicated by the arrow K, and is not sucked into the connecting pipe. There was a problem.

Therefore, the present invention has been made to solve the above-mentioned various problems, and an object of the present invention is to prevent dust or foreign matter flowing through an opening of a lower cover from opening the adjusting lever partition. Regardless, the present invention provides a suction device for a vacuum cleaner in which all suction is performed into a connecting pipe, thereby increasing suction efficiency and removing a vibration phenomenon of the turbine to reduce noise generation. Is to do.
