Brief description of the drawings

Fig. 1 is the utility model circuit diagram.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of touch-induction-type shaver, including pad SB1, the pad SB1 and No. 3 ports for being connected to switch S1, resistance R1, electric capacity C1 and touch chip IC, the switch S1 concatenations There are VCC, the output head grounding of the resistance R1, the bottom crown of the electric capacity C1 and No. 2 ports, touch-controls for being connected to touch chip IC No. 4 ports of chip IC, touch chip IC No. 6 ports, ground wire and electric capacity C2, the top crown of the electric capacity C2 are simultaneously connected to touch-control No. 5 ports of chip IC and VCC, No. 1 port of the touch chip IC are serially connected with single-chip microcomputer S No. 1 port by data wire, No. 2 ports ground connection of the single-chip microcomputer S, No. 3 ports of the single-chip microcomputer S are serially connected with resistance R2, the output end of the resistance R2 And it is connected to resistance R3 and triode Q1 base stage, the output end of the resistance R3 and the emitter stage for being connected to ground wire and triode Q1, The collector series connection of the triode Q1 has motor M, the output end of the motor M and 4 ports for being connected to VCC and single-chip microcomputer S.
