AI Technical Summary
Technical Problem
Existing razors lack non-mechanical head detection functions, which may cause the motor to start without a head, affecting the head's lifespan and potentially injuring the user. Furthermore, mechanical detection is susceptible to wear and interference.
Method used
A current detection module is used to detect the motor current in real time. The current value is used to determine whether the cutter head is installed. The control chip controls the motor to start or stop based on the current signal, and the indicator tells the user the status of the cutter head.
Benefits of technology
It achieves non-mechanical tool head detection, improves detection accuracy and reliability, avoids damage caused by starting without a tool head, and has a simple structure and low cost.

Abstract
The utility model provides a razor belongs to the pruning tool technical field, it has solved the current razor to detect whether the cutter head through mechanical type, the detection precision is lower, is vulnerable to outside interference etc. The control mainboard of this razor is provided with control chip and the current detection module for detecting motor current, control chip can control motor start or close, and the current detection module will detect the current signal transmission to control chip, and control chip can judge whether to close motor according to current signal. The utility model discloses through setting current detection module real -time detection motor's current value, judges whether the cutter head has been installed on the razor through the size of current value, when the current value detected is less than the normal working current of motor connection with cutter head, then judges for the cutter head not to have been installed on the razor, and control chip controls motor to close.
