Table 1 below indicates electric blowing machine corresponding with the state for lifting detection switch 47 and posture detection switch 46, rotation
The state of brush motor 44 and driven roller motor 45b, and the level of " PB current detecting " signal.
If microcomputer 110 judges that the level of " PB current detecting " signal as the stabling current flowed in R304, makes to locate
Stop in the electric blowing machine 11 of free standing condition.If judge the level of " PB current detecting " signal as rotating brush motor 44 and
Driven roller in the movement of motor 45b or stop which of (in addition to press in operation starting stop button (SW104)
And receive except the state for stopping instruction) when, then so that electric blowing machine 11 is worked.
As shown in table 1, section port body 40 is raised from ground and lifts the disconnection of detection switch 47, even if then rotating brush electricity consumption
Motivation 44 and driven roller are in the state stopped with motor 45b, and microcomputer 110 also makes electric blowing machine 11 work.
For example, it is contemplated that removing section port body 40 to user, and brush component 13 is used as the electric dust collector of hand-held to make
The case where using.When section port body 40 is removed, with identical, " PB current detecting " signal the case where lifting the disconnection of detection switch 47
Level become zero.Though microcomputer 110 has been removed without Direct Recognition to section port body 40, even if due to current value
It is zero electric blowing machine 11 also to be made to work, therefore may be used as electric dust collector.
In this way, even if not identifying the shape for lifting detection switch 47 and posture detection switch 46 for microcomputer 110
The wiring of the landing state of state or section port body 40 can also suitably make electric blowing machine 11 work and stop according to situation.

Switch is input in latch cicuit 106 (SW signal shown in Figure 13) for the signal opened is latched.Lock is connected as triggering
Circuit 106 is deposited, and the Q1 disconnected is connected.When Q1 is connected, voltage is supplied to voltage-stabilized power supply circuit 111, and 5V power initiation.
When 5V power initiation, 5V voltage is supplied to the power supply i.e. VDD terminal of microcomputer 110, and is connected to RESET
The C16 of terminal charges via R50, releases reset shortly after.In this way, the processing of microcomputer 110 starts.
In addition, power supply is supplied to drive circuit 112, dust detection circuit 114, amplification electricity when 5V power initiation
Road 113 etc., and each circuit works.As a result, microcomputer 110 is able to detect that user to starting stop button
(SW104) and the operation of attraction switching push button (SW102) it can light, and according to the operation and extinguish LED201~203.This
Outside, it becomes able to control the movement of electric blowing machine.Further, the level of " PB current detecting " signal is read to be able to detect
Rotating brush motor 44 and driven roller with motor 45b are also off in work, and whether section port body 40 is in supporting oneself
Posture.
If passed through after starting stop button (SW104) is pressed and stops electric blowing machine 11 without any operation
Defined period (for example, 3 minutes) are crossed, then microcomputer 11 exports " POW_OFF " signal and closes 5V power supply.In addition,
After section port body 40 be in self-support posture in the state that power supply is closed, without any operate the case where have passed through the period
Under, it also exports " POW_OFF " signal and closes 5V power supply.As a result, for making microcomputer 110 and other circuits in standby
