Dust collect plant installation and measuring switch 57 possesses operating parts 57A.Before dust collect plant 50 is installed on main casing 10, the top of operating parts 57A by helical spring (not shown) application of force and from dust collect plant 50 to this dust collect plant 50 is outstanding.As shown in Figure 1, if use above-mentioned bolt B 1 that dust collect plant 50 is installed on to main casing 10, the outer bottom of main casing 10 is resisted helical spring elastic force operating parts 57A is pressed in dust collect plant 50.Thus, dust collect plant installation and measuring switch 57 becomes on-state.
Photodiode D5 is incorporated in the housing recess 64 of dust collect plant 50, and this housing recess 64 is formed on the opposed position with above-mentioned through hole H (with reference to Fig. 1).Thus, photodiode D5 and light emitting diode D1 arranged opposite.Microcomputer 58 is connected with motor M2, dust collect plant installation and measuring switch 57 and photodiode D5 for control of dust by each holding wire S5 to S7 etc.
Next, the action of the percussion drill 1 with dust collection function of present embodiment is described.Staff near bore position P1, and makes adsorption section 47 be connected to above-mentioned machined surface S (with reference to Fig. 1) control of dust connector 45.Afterwards, if staff make switch operating rod 31 in on-state, make on-off switch S1 be connected in terminal T1, to the energising of drive motors M and to the charging of integrating circuit (capacitor C 1), start.Thus, drive motors M rotation, this rotation is passed to rotation/hit agency 11, thereby starts to utilize the boring work of boring 13 couples of bore position P1 of screwdriver bit.
Afterwards, when the charging voltage of capacitor C 1 becomes above-mentioned threshold voltage when above, positive-negative-positive triode TR1 becomes on-state.With it mutually everywhere, by light emitting diode D1 is switched on, this light emitting diode D1 bright light.Thus, photodiode D5 accepts the light that light emitting diode D1 sends.When photodiode D5 accepts the above-mentioned light time, by holding wire S7, the signal of telecommunication (being subject to light detecting signal) with the magnitude of voltage corresponding with being subject to luminous intensity is sent to microcomputer 58.Wherein, photodiode D5 is an example of bright light test section of the present invention.
Microcomputer 58 uses the program in ROM that is stored in, magnitude of voltage based on comprised by light detecting signal, judge photodiode D5 after light emitting diode D1 is subject to light, to whether receiving on-state detection signal from dust collect plant installation and measuring switch 57, judge.As shown in Figure 1, dust collect plant 50 is installed on to main casing 10, the outer bottom that utilizes main casing 10 is pressed into dust collect plant 50 when interior by operating parts 57A, dust collect plant installation and measuring switch 57 sends on-state detection signal by holding wire S6 to microcomputer 58.Wherein, dust collect plant installation and measuring switch 57 and operating parts 57A are an example of installment state test section of the present invention.
Microcomputer 58 is subject to light and judges receive on-state detection signal in the situation that from light emitting diode D1 judging photodiode D5, to sending with the energising gauge tap (not shown) being connected between motor M2 and battery B the signal that goes code at control of dust, carry out the control that this energising gauge tap is switched from off-state to on-state.Like this, microcomputer 58 starts to carry out to control of dust the control with motor M2 energising.By control of dust is switched on motor M2,56 rotations of control of dust fan.Wherein, microcomputer 58 is examples for operation control section of the present invention.
Along with 56 rotations of control of dust fan, the dust producing from bore position P1 flows into control of dust space 46, and from dust collecting opening 63, flows into disposal box 60 through dust collection hose 40.The dust that flows into disposal box 60 is caught and is stranded in this disposal box 60 by filter 55.
When in order to make above-mentioned boring end-of-job, staff makes switch operating rod 31 in off-state, while making on-off switch S1 be connected in terminal T2, to the energising of drive motors M and to the charging of capacitor C 1, stops respectively.With it mutually everywhere, the action of boring screwdriver bit 13 stops, and capacitor C 1 electric discharge, according to time constant and the charging voltage slow decreasing of capacitor C 1.Therefore,, even in the situation that the action that staff makes switch operating rod 31 make drive motors M and bore screwdriver bit 13 in off-state stops, before the charging voltage of capacitor C 1 is lower than above-mentioned threshold voltage, positive-negative-positive triode TR1 still maintains on-state.
Positive-negative-positive triode TR1 maintain on-state during, photodiode D5 continues to accept the light that light emitting diode D1 emits.Thus, during becoming lower than threshold voltage to the charging voltage of capacitor C 1, can make as mentioned above 56 rotations of control of dust fan after staff has just been made as off-state by switch operating rod 31, make dust flow into disposal box 60.Wherein, variable resistor VR1 and the capacitor C 1 of decision time constant are examples of the delay portion that turns off the light of the present invention.
And after having passed through official hour, when the charging voltage of capacitor C 1 becomes lower than threshold voltage, positive-negative-positive triode TR1 is changed to off-state from on-state.Thus, light emitting diode D1 turns off the light, and photodiode D5 can not be subject to light from light emitting diode C1.
Afterwards, microcomputer 58 is when the magnitude of voltage that comprised by light detecting signal based on receiving from photodiode D5, judge photodiode D5 and from light emitting diode D1, be not subject to the light time, to energising gauge tap (not shown), send open command signal, thereby carry out the control that this energising gauge tap is switched from on-state to off-state.Like this, microcomputer 58 makes to stop with the energising of motor M2 to control of dust.Thus, the spinning movement of control of dust fan 56 stops.
In above-mentioned example, be that dust collect plant 50 is installed on to main casing 10, makes the dust being produced by bore position P1 flow into disposal box 60, but for example, under the state of in order to alleviate the weight of percussion drill, dust collect plant 50 being pulled down from main casing 10 and dust collection hose 40 being connected with dust collecting opening 63, also can make above-mentioned dust flow into disposal box 60.Below the example that makes dust flow into disposal box 60 is described.
Staff can accept the position configuration dust collect plant 50 from the light of light emitting diode D1 at photodiode D5.Next, staff utilizes finger that operating parts 57A is pressed in dust collect plant 50.Thus, dust collect plant installation and measuring switch 57 sends above-mentioned on-state detection signal to microcomputer 58.
Then, as mentioned above, when microcomputer 58, judge photodiode D5 and from light emitting diode D1, be subject to light and judge while receiving on-state detection signal, start to carry out the control to the energising of control of dust fan 56, thereby make 56 rotations of control of dust fan.Thus, identical with above-mentioned example, dust flows into disposal box 60, and this dust is stranded in disposal box 60.Wherein, dust collect plant 50 is examples for dust collect plant for electric tool of the present invention, and operating parts 57A is the example that operating condition of the present invention starts operating portion.
In addition, in the situation that pulling down, make dust to flow into disposal box 60 from main casing 10 dust collect plant 50, identical with above-mentioned example, after staff has just been made as off-state by switch operating rod 31 till during the charging voltage of capacitor C 1 becomes lower than threshold value, can make dust flow into disposal box 60.
The effect > of < present embodiment
In the percussion drill 1 with dust collection function of present embodiment, photodiode D5 accepts the light that light emitting diode D1 sends, thereby utilize as described above microcomputer 58 to judge photodiode D5 and from light emitting diode D1, be subject to the light time, start to carry out to control of dust the control with the energising of motor M2, thereby make 56 rotations of control of dust fan.
Therefore, unlike the prior art, in order to make 56 rotations of control of dust fan, there is no need to make the axle of drive motors M outstanding from main casing 10, and there is no need to make control of dust outstanding from dust collect plant 50 with the output shaft of motor M2.
Thus, because between main casing 10 and axle, all can not produce gap between the outer peripheral face of dust collect plant 50 and output shaft, enter main casing 10 or dust collect plant 50 so can suppress dust.
In addition, because the axle that there is no need to make drive motors M is from main casing 10 and there is no need to make control of dust outstanding from dust collect plant 50 with the output shaft of motor M2, therefore not having accidental power directly puts on axle or output shaft, thereby can suppress axle or output shaft damage.
In addition, for the percussion drill without dust collection function, also as long as dust collect plant 50 is disposed to the position of the light that light emitting diode that photodiode D5 can accept this percussion drill emits, can be not make control of dust from the outstanding mode of dust collect plant 50, control of dust fan 56 be rotated with the output shaft of motor M2.
Therefore, identical with the above-mentioned percussion drill 1 with dust collection function, can suppress dust and enter dust collect plant 50, and can suppress output shaft damage.
And, as mentioned above, even make switch operating rod 31 in off-state and after drive motors M, the action of boring screwdriver bit 13 stop staff, also can positive-negative-positive triode TR1 maintain on-state during (official hour), photodiode D5 continues to accept the light that light emitting diode D1 emits.Thus, positive-negative-positive triode TR1 maintain on-state during, microcomputer 58 is made photodiode D5 and from light emitting diode D1, is subject to the judgement of light, thereby makes the control of control of dust fan 16 rotation.
Therefore, even after the action that makes drive motors M or brill screwdriver bit 13 stops, also can positive-negative-positive triode TR1 maintain on-state and photodiode D5 accept light that light emitting diode D1 sends during, utilize the control of dust fan 16 of rotation status to make dust flow into disposal box 60.Therefore, dust is difficult to residue in dust collection hose 40 etc.
In addition, based on changing according to the time constant of the integrating circuit in existing circuit 17 (variable resistor VR1, capacitor C 1) time that positive-negative-positive triode TR1 maintains on-state, thereby after stopping, the action of drive motors M or brill screwdriver bit 13 also can make dust flow into disposal box 60.Thus, after need to not stopping for the action that makes drive motors M or bore screwdriver bit 13, do not make dust flow into disposal box 60, and in circuit 17 additional new circuit.
The manufacturing cost of percussion drill 1 that therefore, can inhibition zone dust collection function raises.
In addition in addition, in the situation that microcomputer 58 is judged photodiode D5, from light emitting diode D1, be subject to light and judge to receive the on-state detection signal being sent by dust collect plant installation and measuring switch 57, start to carry out to control of dust the control with the energising of motor M2.
Therefore, the in the situation that not being installed on main casing 10 due to dust collect plant 50, microcomputer 58 not receiving on-state detection signal, even if judge photodiode D5, from light emitting diode D1, be subject to light, also cannot carry out the control with the energising of motor M2 to control of dust.
Thereby, before dust collect plant 50 is installed on main casing 10, can prevent 56 misoperations of control of dust fan.
And, in the situation that dust collect plant 50 is pulled down and is made dust flow into disposal box 60 from main casing 10 in order to alleviate the weight of percussion drill, as long as staff does not make microcomputer 58 receive the on-state detection signal being sent by dust collect plant installation and measuring switch 57 by operating parts 57A being pressed in dust collect plant 50, just can not start to carry out the control with the energising of motor M2 to control of dust.
Therefore,, before operating parts 57A being pressed in dust collect plant 50 by staff, can prevent 56 misoperations of control of dust fan.
The present invention is not limited to above-mentioned embodiment, can suitably change a part for formation and implement in the scope of purport that does not depart from invention.For example, also can replace operating parts 57A and form dust collect plant installation and measuring switch 57 with various detecting elements.As an example, also can replace operating parts 57A and use photodiode, when dust collect plant 50 is installed on main casing 10 and has blocked the irradiation to the light of photodiode, can detect dust collect plant 50 and be installed on main casing 10.
And except being disposed at horizontal direction for boring on wall, the dust producing when holing on floor etc. with the percussion drill 1 of dust collection function also can be disposed at vertical is stranded in disposal box 60.In addition, for the electric tool the percussion drill 1 except with dust collection function, also can apply the present invention.In addition, also can be by light emitting diode D1 so that only bright light, the mode of turning off the light are arranged at the lower surface of main casing 10 or side etc. in linkage with the action of drive motors M.
