[Prior art]
A conventional dust collector will be described with reference to FIGS. 5 is a front view showing a conventional dust collector, FIG. 6 is a left side view of the dust collector shown in FIG. 5, and FIG. 7 is a plan view of the dust collector shown in FIG. As shown in FIGS. 5 to 7, a general portable dust collector has a tank portion 5 for storing dust, liquid, etc. conveyed through a duct hose (not shown). A head unit 4 having a motor or the like as a driving source is detachably attached to the unit 5, so that dust or the like accumulated in the tank 5 can be discarded after the head unit 4 is detached from the tank unit 5. It is configured.
[0003]
The head unit 4 is provided with a dust collecting fan rotated by a motor, a switch 3 for starting and stopping the motor, and the head unit 4 is viewed from above depending on the shape of the motor and the dust collecting fan. In addition to the substantially circular shape, the opening above the tank portion 5 corresponding to the head portion 4 is also substantially circular.
[0004]
Further, the tank unit 5 is provided with a clamping device 9 for fixing and releasing the head unit 4, a connection unit 7 to which a duct hose for transferring dust and the like can be attached and detached.
[0005]
In such a configuration, when the switch 3 is turned on, the dust collecting fan is rotated by the motor, and a suction force is generated in the duct hose through the tank portion 5, and dust or the like passes through the duct hose using this suction force. It is transported and stored in the tank unit 5. When the dust collection in the tank unit 5 is discarded, the clamping device 9 is released, the head unit 4 is lifted upward and removed from the tank unit 5, and the collected dust is discarded by turning the tank unit 5 overside. is doing. After disposal, the head unit 4 is placed on the tank unit 5 that has been rebuilt, and is fixed at a free position by the clamp device 9.
[0006]
However, in the above-described dust collector, when the operator places the head unit 4 on the tank unit 5, there is nothing that regulates the rotational direction of the substantially circular head unit 4 having the switch 3. The connection part 7 and the switch 3 mounting surface of the head part 4 are hardly located on the same straight line, and the present situation is that they are incorporated unconsciously without the operator being aware of it. For this reason, after assembling the head part 4 and the tank part 5, when the dust collecting work is performed, the operator notices that the switch 3 surface is not facing the operator side, that is, the work is performed while pulling the dust collector body with the duct hose. Since the side is the worker position, if there is no switch 3 surface at this position, the worker has to go around the dust collector body and operate the switch 3. In other words, since it is necessary to operate the switch 3 every time work is started, interrupted, or terminated, if there is no switch 3 surface at an appropriate position, it takes time to turn the switch 3 on and off. There was a problem of inviting a decline.
[0007]
