Abstract
The utility model provides a display device for the rotating speed and rotating number of an electric tool. The electric tool comprises a working head of an action workpiece, a motor driving the working head, and an impeller which is arranged between the working head and the motor and fixedly connected with a motor shaft, wherein the display device for the rotating speed and the rotating number of the electric tool comprises a data conversion circuit board, a detecting head which is electrically connected with the data conversion circuit board, a display screen connected with the data conversion circuit board, and a battery which provides electric power for the data conversion circuit board; the impeller is also provided with a photosensitive label; and when the electric tool is started, the detecting head detects the photosensitive label, and outputs the rotating speed and the rotating number of the impeller to the display screen by the data conversion circuit board. Compared with the prior art, the display device has the benefits of being convenient in operation, and good in user experience, and prolonging the service life of the electric tool.
Description
Technical field
The utility model relates to a kind of electric tool rotating speed and revolution number display device, especially relates to a kind of novel electric tool rotating speed and life-span to count electronic display unit.
Background technology
General, electric tool all is by a motor-driven working head, makes working head drive work package and carries out work.And existing electric tool can't show the rotating speed of electric tool, so that in use, can only control this rotating speed by operating personnel's experience, operates not convenient; In addition, when using this electric tool, can't when stifled boring, in time allow operating personnel know, cause motor to damage easily, reduce electric tool service life; Simultaneously, existing electric tool also can't show its life-span number, thereby can't learn the electric tool access times, the revolution of motor accumulative total when it damages, and cause the user can't judge that this electric tool is new and old, and the quality of judging electric tool, the user experiences bad.
The utility model content
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of novel electric tool rotating speed and life-span to count electronic display unit.
The purpose of this utility model is achieved through the following technical solutions:
A kind of electric tool rotating speed and revolution number display device, described electric tool comprises the working head of an effect work package, one drives the motor of described working head, and be arranged at impeller between described working head and described motor, described impeller is fixedly connected on described motor shaft, wherein, described electric tool rotating speed and revolution number display device comprise a data converting circuit plate, one electrically connects the detecting head of described data converting circuit plate, and one connect the display screen of described data converting circuit plate and the battery that continues electric power be provided for described data converting circuit plate, also be provided with a photosensitive mark on the described impeller, when described electric tool started, described detecting head was surveyed described photosensitive mark and is exported the rotating speed of described impeller and revolution to described display screen by described data converting circuit plate.
Further, described battery is a button cell.Described detecting head is an infrared detection head.
Again further, described display screen comprises two viewing areas that show electric tool rotating speed and revolution.
Further, described electric tool is electric portable drill, electric hammer, screwdriver, tapping machine.
Compared with prior art, the beneficial effects of the utility model are: operation is convenient, improves electric tool service life, and the user experiences.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1 is according to the utility model preferred forms electric tool housing inner structure schematic diagram.
Fig. 2 is according to the utility model preferred forms electric tool impeller front view.
Fig. 3 is according to the utility model preferred forms electric tool vertical view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The utility model has disclosed a kind of novel electric tool rotating speed and revolution number display device, as Fig. 1, shown in Figure 2, in the utility model preferred forms, described electric tool is a hand-held type electric tool, it comprises a grip part 1, and one protrude in housing and act on the working head 3 of work package, described working head 3 is located at the motor 5 driving work in the described electric tool housing, wherein, be provided with an impeller 7 that is used for cooling motor 5 at described working head 3 and 5 in described motor, described impeller 7 is fixedly connected on the main shaft of described motor 5, and keeps relative static with the main shaft of described motor 5.
Described electric tool comprises that also one is arranged at the data converting circuit plate 9 in the described housing, on described data converting circuit plate 9, electrically connect a detecting head 91, these detecting head 91 detectable photosensitive marks 71 that are arranged on the impeller 7, thus the rotating speed and the revolution of this impeller 7 detected.General, this detecting head 91 can draw photosensitive sign 91 exactly and turn around the required time on impeller 7, under the radial distance situation of the described relatively impeller 7 of known photosensitive mark 71, can calculate the rotating speed of impeller 7 by data converting circuit plate 9 automatically, simultaneously, also can survey described photosensitive mark 71 by described detecting head 91, and cooperate described data converting circuit plate 9 to count the revolution of impeller 7, be fixedly connected on the main shaft of described motor 5 because of impeller 7, its rotating speed and revolution be the same with described motor 5 main shafts all, so rotating speed and the revolution that can understand described motor 5 by the rotating speed and the revolution of described impeller 7.
Described data converting circuit plate 9 electrically connects a battery 93, in the best enforcement of the utility model, described battery is a button cell 93, described button cell 93 is arranged in the described electric tool housing, and provide lasting running current for described data converting circuit plate 9, effect is when electric tool cuts off the power supply, and this button cell 93 still is used to make it the revolution of memory electrical machine for 9 power supplies of described data converting circuit plate, i.e. life-span of motor as can be known.As shown in Figure 3, a display screen 95 is arranged on the described electric tool housing, comprises two viewing areas on it, and one can show the rotating speed 951 of this electric tool motor 5, and its two revolution 952 that can show this electric tool motor 5 is checked to make things convenient for the user.
Although be the example purpose, preferred implementation of the present utility model is disclosed, but those of ordinary skill in the art will recognize that under situation about not breaking away from by the disclosed scope and spirit of the present utility model of appending claims, various improvement, increase and replacement are possible.
