Electric wine bottle opener

Abstract

An electric wine bottle opener comprises an MCU, a timer in the MCU and a motor, a drive circuit is arranged between the MCU and the motor, the drive circuit comprises a current drive amplifying circuit, a drive control circuit and a filter circuit, an I / O port of the MCU is arranged in the mode that the output end of the MCU is connected with the input end of the drive circuit, and the output end of the drive circuit is connected with the input end of the filter circuit. The output end of the driving circuit is connected with the positive electrode and the negative electrode of the motor, the MCU controls the rotation direction of the motor through the driving circuit, the current driving amplification circuit is an RZ7886 chip, and the driving circuit further comprises a voltage stabilization bias circuit used for guaranteeing normal work of the RZ7886 chip. On the current driving amplification circuit, one driving IC chip RZ7886 is used for replacing an original bridge type motor driving circuit composed of two N-MOSFETs, two P-MOSFETs and two triodes, so that the circuit structure is simpler, the circuit integration degree is higher, and the manufacturing cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of portable household appliances, in particular to an electric wine bottle opener circuit. Background technique [0002] The bridge motor drive circuit composed of two N-MOSFETs, two P-MOSFETs and two triodes uses many electronic components and has a complex circuit structure, which has high requirements for the production of circuit boards. The performance is easily affected by the differences in the circuit board process and electronic components, which will affect the normal operation of the bottle opener and affect the user's use. The bridge-type motor drive circuit is composed of several basic electronic components, the production efficiency is low, and the circuit integration is not high, resulting in a large volume of the produced circuit board, which cannot meet the current market requirements for product portability. Electronic components are more expensive to produce and more expensive to maintain...
