Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable dust collector for sucking fallen leaves scattered on the ground.

[0002]

2. Description of the Related Art A conventional portable dust collector will be described with reference to FIGS. At the time of the work, the worker holds the work while holding the tip of the nozzle portion 2 toward the ground 9. At this time, the product is held while having an appropriate inclination with respect to the ground, and furthermore, an appropriate space is provided between the tip of the nozzle portion 2 and the ground 9. The main body 1 has a built-in motor, and a fan is attached to the tip of the rotating shaft of the motor. Air paths 3, 4, and 5 are provided in the nozzle section 2.

[0003] During operation, the rotation of the motor generates airflow from the fan, and this airflow flows through the air passages 3 and 4 by arrows 6 and 7.
Flow in the direction. The airflow in the air passage 3 is blown out from the outlet 8 toward the ground 9, and the fallen leaves 10 scattered on the ground rise from the ground 9. On the other hand, the direction of the airflow in the air passage 4 is changed by the airflow
From the air outlet 5 and flows in the direction of arrow 13. The air pressure at the end of the air passage 5 becomes lower than the outside air pressure due to the ejector effect due to this air flow.
4, is sucked into the air passage 5, and at this time, the fallen leaves 10 floating from the ground 9 are sucked together with the outside air by the airflow from the air outlet 8. Further, the outlet 8 was located above the suction port 14.

[0004]

In the portable dust collector described above, the air outlet is located above the suction port, and the nozzle is used with the tip of the nozzle inclined forward during work. There is a problem in that the work efficiency is reduced because a part of the fallen leaves or the like that have risen from the ground due to the airflow injected from the nozzle is blown forward without being sucked into the nozzle from the suction port.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, improve the working efficiency by changing the positions of the airflow outlet and the suction port, and blow off falling leaves and the like in the direction of the suction port.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to position the airflow outlet below the suction port so that the fallen leaves floating above the ground are blown off immediately below the suction port by the airflow from the airflow outlet. It is achieved by doing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable dust collector according to the present embodiment will be described with reference to FIGS. The housing 1 has a built-in motor as a drive source (not shown), and a fan is attached to the end of the rotating shaft of the motor. Further, a plurality of air paths 3, 4,
5 are provided. During operation, an airflow is generated from the fan by the rotation of the motor, and the airflow flows in the directions of arrows 6 and 7 in the first air passage 3 and the second air passage 4 which are the air passages. Then the first
The air flow in the air passage 3 is blown out from the outlet 8 toward the ground 9,
The fallen leaves 10 scattered on the ground are lifted off the ground. On the other hand, the airflow in the second air passage 4 is
The flow direction is changed, and the air is ejected from the outlet 12 to the third air passage 5 and flows in the direction of the arrow 13. Since the air pressure at the front end of the air passage becomes lower than the outside air pressure due to the ejector effect of this air flow, the outside air near the suction port 14 is sucked into the air passage 5 from the suction port. At this time, since the outlet 8 is located below the suction port 14, the floating leaves 10 are blown off directly below the suction port 14 by the airflow from the outlet 8, so that all of the raised leaves are removed. The air is sucked into the third air passage 5 from the suction port 14 together with the outside air.

[0008]

According to the present invention, by arranging the airflow outlet below the suction port, the airflow injected from the airflow outlet at the time of work allows all the leaves and the like floating above the ground to be simultaneously lifted off the ground. It can be blown off directly below the suction port, and the working efficiency can be improved.
