Description
Technical field
The utility model relates to a kind of pruning tool, refers in particular to a kind of induction speed governing shaver.
Background technology
Shave a mao instrument and comprise hair scissors, shaver, shaver, the products such as Ms's machine or man's machine, it is for pruning the hair of human or animal, in use, it needs driven by motor cutter head to work long hours, work long hours at a high speed, then power wastage can be caused, and when cutter head carries out cut operation, hair can make the electric current of motor strengthen to the resistance of cutter head, thus cutter head is generated heat, cutter head is when fitting scalp, scalp may be caused to scald, and, long big current is through motor, electrical machinery life can be caused to reduce, improve noise simultaneously, and when shaving a mao instrument and being in low-speed running state, because rotating speed is lower, the sharpness of its cutter head is too low, well can not shave hair, and low speed can make shear feel reduce, when rotating speed lower with shakiness, the shearing feel that user is good cannot be provided, especially for the hairdressing personnel of specialty, not good shearing feel also can reduce its craftmanship.
When therefore needing now a not shave mao, comparatively low velocity running can be kept, reduce noise, and when haircut, automatically switch into the state of running up, the sharpness of raising cutter head.
Utility model content
In order to solve above deficiency, the utility model provides a kind of induction speed governing shaver.
The utility model provides: a kind of induction speed governing shaver, it comprises handle, described handle front end arranges shave head, described shave head is connected with motor, described motor is placed in handle, power supply and control module is also had in described handle, described control module comprises MCU control unit, judge whether to be in for detecting current of electric the current detecting unit shaving mao state, for detecting the velocity sensor of motor speed, for the driver element of drive motors, described current detecting unit and velocity sensor are connected with motor and MCU control unit respectively, described driver element is connected with MCU control unit and motor respectively.
Described control module is provided with sensing unit.
Described sensing unit comprises start unit and range sensor, and described range sensor is connected with start unit.
Described MCU control unit comprises for the memory cell of storaging current preset value, the comparing unit that compares with the initial current prestored for the electric current that detected by current detecting unit.
Described control module comprises charhing unit.
Described control module comprises display unit.
Described control module comprises switch element, and described switch element is connected with the starting switch be arranged on handle.
The utility model detects the curent change of motor by current detecting unit, when its electric current is less, then reduce the rotating speed of motor, and when shave head shaves hair operation, motor due to shave head shave hair be obstructed time, electric current can become large, now MCU control unit then improves the rotating speed of motor by driver element, the shear rate of shave head is accelerated, and Negotiation speed sensor detects the shear rate of shave head and the rotating speed of motor in real time, electric current real-time change is guaranteed, to ensure that shear rate is constant by MCU control unit.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, this application provides a kind of induction speed governing shaver, described shaver can be hair scissors, wool product shaved by shaver, shaver, Ms's machine or man's machine etc.
This shaver comprises a handle, handle front end arranges shave head 3, motor 2 is set in handle, power supply and control module, Power supply, motor 2 is connected with shave head 3, described control module comprises MCU control unit 1, for detecting the current detecting unit 5 of motor 2 electric current, for detecting the velocity sensor 4 of motor 2 rotating speed, for the driver element 6 of drive motors, MCU control unit 1 detects the real-time current change of motor 2 by current detecting unit 5, when shave head 3 leaves fur, because shave head 3 is not obstructed, shave head 3 drag reduction, MCU control unit 1 directly controls motor 2 speed of service by driver element 6, make it decline at once, maintain low cruise, reduce current loss, and when shave head 3 runs into hair, hair cut produces resistance, the electric current of motor 2 can increase, the now electric current of MCU control unit 1 control motor 2, by improving electric current, the speed of service is accelerated, increase shave head 3 and cut moment, and velocity sensor 4 is for detecting the rotating speed of motor in real time, when electric current changes, real-time speed governing is carried out by detecting rotating speed, and it is when shaving hair operation, also the change of Negotiation speed the adjustment of electric current can be carried out, guarantee when to shave mao due to difference cutting dynamics that the hardness of hair or density difference cause, speed governing can be carried out in real time, guarantee that shearing dynamics can increase with the hardness of hair or variable density or reduce.
Described MCU control unit 1 comprises for the memory cell of storaging current preset value, the comparing unit that compares with the initial current prestored for the electric current that detected by current detecting unit, this electric current that prestores is then the operating current of motor 2 when shave head 3 and hair contact, for distinguish now shave head 3 whether with hair contact, distinguish the two states of shave head 3 when to shave mao or when not shave mao, regulate to realize speed.
The application can also be provided with sensing unit simultaneously, whether this sensing unit contacts with skin or fur for detecting shaver, detected the distance of shave head 3 and skin or fur by range sensor 8, control start unit 7 and work, when shave head 3 contacts with skin or fur, it starts control module, shave head 3 is started working, and when shave head 3 is away from skin or fur, range sensor 8 is examined distance and is become greatly, it is closing control module then, with economize energy.
Described control module comprises charhing unit, and it is connected with power supply, is charged by charhing unit.
Described control module comprises display unit 11, is connected with MCU control unit 1, for display speed or current value, also may be used for showing charged state, also may be used for showing battery electric quantity.
Described control module comprises switch element 9, and described switch element 9 is connected with the starting switch 10 be arranged on handle, for manually opened.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection domain of the present utility model.
