Control device of bluetooth nasal hair trimmer

Abstract

The invention provides a control device of a bluetooth nasal hair trimmer. The defect that the traditional nasal hair trimmer cannot be additionally provided with control and display functions due to size limitation is overcome. By transmitting control signals through bluetooth, the monitoring and operation of motor rotating speed, temperature and electric quantity are realized. The control device comprises a power supply module, a temperature acquisition module, a motor control module, a charging module, a display module and a MCU module, wherein the power supply module is used for receiving external voltage and converting the external voltage to working voltage; the charging module is used for executing charging operation; the motor control module is used for controlling the starting, stop and rotating speed of a motor; the temperature acquisition module is used for measuring the working temperature of the motor; the display module is used for displaying use state information; and the MCU module is used for realizing a logic control function and transmitting temperature acquisition information, motor rotating speed acquisition information and electric quantity acquisition information to an upper computer in a bluetooth mode.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control device for a Bluetooth nose hair trimmer. Background technique [0002] Along with the raising of people's living standard, along with people gradually pay attention to appearance modification, electric nose hair trimmer is also more and more accepted by the public as a kind of beauty tool. Electric nose hair trimmers in the prior art generally adopt a handheld design with a built-in battery and motor-driven blades. However, due to the size of the trimmer, it cannot accommodate a display screen and more operation buttons, resulting in a single function and cannot be added to the monitoring of the motor speed. And adjustment, and because the temperature sensor cannot be installed, the temperature cannot be sampled during use, and the overheating protection of the motor is adopted, which also causes a lot of potential safety hazards.
