Nail Clipping Device with a Warning Module

Abstract

A nail clipping device with warning functions is disclosed, including: a nail clipper with arc-shaped cutting edges; a capacitive sensing module, located below the arc-shaped cutting edges of the nail clipper, enables measurement of the distance between the arc-shaped cutting edges of the nail clipper and the flesh below the nail; a warning module, located above the arc-shaped cutting edges of the nail clipper; and a control module, located at the lower portion of the device, and coupled to the capacitive sensing module and the warning module, capable of pre-setting a warning distance and comparing its corresponding reference voltage with variable sensing voltage, the control module amplifies and filters the output signal from the capacitive sensing module after voltage comparison, driving the warning module to emit a warning signal when the distance between the arc-shaped cutting edges of the nail clipper and the flesh below the nail is shorter than the warning distance.

1 . A nail clipping device with warning functions, comprising:
 a nail clipper body, with cutting edge portions placed on one end;   a capacitive sensing module, placed below said cutting edge portions of said nail clipper body, acting as a detection device; and   a warning module, coupled to said capacitive sensing module and responsive to said capacitive sensing module for issuing warning.   
     
     
         2 . The nail clipping device with warning functions of  claim 1 , further comprising a button cell located within said nail clipping device, for supplying power to said capacitive sensing module and said warning module. 
     
     
         3 . The nail clipping device with warning functions of  claim 2 , wherein said button cell comprises: lithium cells, mercury oxide cells, alkaline manganese cells, mercury cells, nickel metal hydride cells, and nickel cadmium cells. 
     
     
         4 . The nail clipping device with warning functions of  claim 1 , wherein said capacitive sensing module comprises: single chip micro-controller unit or programmable system on chip. 
     
     
         5 . The nail clipping device with warning functions of  claim 4 , wherein said single chip micro-controller unit has an analog to digital converter with high signal to noise ratio to minimize error, and said programmable system on chip may control compensation parameters for interferences such as temperature, humidity and electrostatic discharge to improve sensing performance. 
     
     
         6 . The nail clipping device with warning functions of  claim 1 , further comprising a control module, located at lower portion of said nail clipping device and coupled to said capacitive sensing module and said warning module, capable of pre-setting a warning distance and compares corresponding reference voltage with variable sensing voltage, amplifies and filters output signal from said capacitive sensing module after voltage comparison, driving said warning module when distance between said cutting edges portions of said nail clipper body and flesh below nail is shorter than said warning distance. 
     
     
         7 . The nail clipping device with warning functions of  claim 1 , wherein said warning module may produce sounds or emit lights to send out warning signals.
