Abstract
The invention provides a rotating speed and revolution number display device of an electrical tool. The electrical tool comprises a working head acting a workpiece, a motor for driving the working head and an impeller arranged between the working head and the motor, wherein the impeller is fixedly connected to a motor shaft. The rotating speed and revolution number display device of the electrical tool comprises a data conversion circuit board, a probe electrically connected with the data conversion circuit board, a display screen connected with the data conversion circuit board and a battery for providing electric power for the data conversion circuit board. A photosensitive mark is arranged on the impeller, and when the electrical tool is started, the probe detects the photosensitive mark and outputs the rotating speed and the revolution number of the impeller to the display screen through the data conversion circuit board. Compared with prior art, the invention has the advantages of convenient operation, service life prolonging of the electrical tool and good user experience.
Description
Technical field
The present invention relates to a kind of electric tool rotating speed and revolution number display device, especially relate 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 serviceable 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, user experience is bad.
Summary of the invention
In order to solve above-mentioned technical matters, the object of the present invention is to provide a kind of novel electric tool rotating speed and life-span to count electronic display unit.
Purpose of the present invention 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 invention has the beneficial effects as follows: operation is convenient, improves electric tool serviceable life, and user experience is good.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1 is according to best mode for carrying out the invention electric tool housing inner structure synoptic diagram.
Fig. 2 is according to best mode for carrying out the invention electric tool impeller front view.
Fig. 3 is according to best mode for carrying out the invention electric tool vertical view.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
The present invention has disclosed a kind of novel electric tool rotating speed and revolution number display device, as Fig. 1, shown in Figure 2, in best mode for carrying out the invention, 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 to be changeed the required time of a figure 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 present invention, 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 invention 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 invention of appending claims, various improvement, increase and replacement are possible.
