Abstract
In order to improve the operation mode of the electrical tool with suction device. A dust extractor (5) connected in parallel with the tool across the supply current source (1), the current circuit of the dust extractor containing one or more switches, for delayed switching of the dust extractor in response to the on-off switching of the tool current circuit (11).
Description
Produce in meeting on the electric tools of dust,, used additional dust exhaust apparatus in order to eliminate healthhazard as far as possible.At first, under the situation of movable electric tool, dust exhaust apparatus is connected with it with electric tools placement spaced apart and by a suction pipe.Usually on the dust exhaust apparatus strainer dirt for a long time, dust exhaust apparatus and electric tool will automatically shut down.Operating personnel then must be interrupted its work, move towards dust exhaust apparatus, normally get off and strainer is made cleaning from a ladder at this moment.Only after strainer purifies end, just can restart electric tools and proceed work.Especially produce in the builing industry of a large amount of dusts in meeting, not only can produce the interruption of work in the case but also produce unnecessary path between each device.
Task of the present invention is, eliminates path between this electric tools and the dust exhaust apparatus in simple mode on the described electric tools of beginning part.According to the present invention, it is to realize like this, being about to electric tools and dust exhaust apparatus is connected on the power supply in parallel, wherein in the current loop of dust exhaust apparatus, be provided with switching device that one or more time-delays discharge, that can be opened or turn-off by electric current in the electric tools current loop, be used to operate dust exhaust apparatus.We just might be by the turning on and off of electric tools now, comes dust exhaust apparatus is carried out remote control switch by its electric current.To or else need between electric tools and dust exhaust apparatus, walk up and down thus.
What meet the requirements is the switching device that is provided with a time-delay release for the driving of dust exhaust apparatus, and this switching device is switched on when flowing through electric current in the electric tools current loop.Dust exhaust apparatus also is connected with power supply forcibly when electric tools is switched on.When electric tools turn-offed, dust exhaust apparatus was used for getting rid of remaining amount of dust specially because time-delay release is still worked a period of time.
According to another characteristic of the invention, be provided with the switching device that made the conducting of filter cleaning part under the situation that a long-time especially time-delay discharges, failure of current in the electric tools current loop on the dust exhaust apparatus with filter cleaning part.Now, when electric tools turn-offs, can carry out the purification of strainer at every turn, and need not operate the special switch that is located on the dust exhaust apparatus.Operating personnel can stay on the operating position during the entire work process always, and the purification of strainer then by the opening and close and carry out of electric tools, is also promptly operated by remote control switch.
What meet the requirements in the case is, in series is provided with the cutoff device that works when flowing through electric current in the current loop at dust exhaust apparatus with conducting device in the current loop of filter cleaning part.In order to reach the purification of turn-offing strainer reliably, in series be provided with a cutoff device that works when in the dust exhaust apparatus current loop, flowing through electric current with conducting device with the electric tools running hours.Because when on the strainer seldom during dirty dirt, do not need when electric tools turn-offs at every turn, to make the filter cleaning part open-minded, therefore in its current loop, be provided with another switching device that is subjected to strainer to become dirty extent control, only when strainer became dirty degree and needs this switching device to connect, this current loop was just connected.Recommendable is to come other two conducting devices that filter purifies part of taking over by a hand switch, makes the filter cleaning part also can irrespectively be switched on and turn-off with electric tools thus.
Accompanying drawing represents to have the sketch plan of a circuit of the electric tools of dust exhaust apparatus and filter cleaning part.
Attaching plug 1 is used for being connected with unshowned power supply.It is connected with a dust exhaust apparatus 5 with 4 by a switch 2 and lead 3.Also be provided with two electromagnet 6 and 7 of the vibrating device 8 that is used for dust exhaust apparatus 5 therewith in parallel.In addition, the voltage source 9 that also is used in electronic section 10 by switch 2 is connected with attaching plug 1.Be connected a socket 12 in switch 2 fronts in parallel by lead 11 and attaching plug 1, it is used for unshowned electric tools.
Current loop at the socket 12 that is used for electric tools is provided with a potential transformer 13 and an amplifier unit 14, and it will control electronic section 10 according to current value.This electronic section has the selector switch 15 of one three position, wherein can realize the pure manual operation of electric tools, dust exhaust apparatus 5 and vibrating device 8 on uppermost position.The centre position is used for the manual vibration that automatically operation and the 3rd position are used for vibrating device 8.Another switch 16 is as the switching device of vibrating device 8 and be subjected to the control of dust exhaust apparatus 5 insufficient pressures and be subjected to the control of the dirty degree of change of unshowned strainer thus.In the current loop of dust exhaust apparatus 5 and vibrating device 8, respectively be connected to a triac 17 and 18.These two bi-directional thyristor switch will be by electronic section 10 controls.
Under the situation of switch 2 closures and electric tools connection, on potential transformer 13, produce voltage by above-mentioned electric current, this voltage makes dust exhaust apparatus 5 conductings by amplifier unit 14 and electronic section 10.Under the situation that electric tools turn-offs, potential transformer 13 no currents will unshowned time-delay mechanism makes dust exhaust apparatus 5 still keep flowing through electric current a period of time in the electronic section 10 by being located at, and preferably about 5 seconds are so that also remaining residue dust can be excluded.
Under the very dirty situation of the strainer of dust exhaust apparatus 5, switch 16 is with closure, so that vibrating device 8 is supplied to voltage by another time-delay engaging means in the electronic section 10 via bi-directional thyristor switch 18.After will making vibrating device 8 be preferably in for 10 seconds, time switch by electronic section 10 is turned off again.Under the situations very dirty and switch 16 closures thus, can make more than 10 ground of vibrating device connect and be operated with turn-offing at strainer by the electric tools that on socket 12, connects.
