Brush head or other accessory recognition system and recognition method based on Hall device

Abstract

The invention discloses a brush head or other accessory recognition system and recognition method based on a Hall device. The system comprises a motor used for driving a brush head or other accessories, a driving circuit connected with the motor, a power conversion circuit, a microprocessor, a Hall element, a brush head or other accessory magnet and a buzzer. The magnet is fixedly arranged on the brush head or other accessories, the Hall element and the magnet are correspondingly arranged and used for obtaining magnetic signals of the magnet, the output end of the Hall element is connected with the input end of the microprocessor, and the signal output end of the microprocessor is connected with the driving circuit and the buzzer. The Hall element converts the obtained magnetic flux into a voltage signal or a switching signal and sends the voltage signal or the switching signal to the microprocessor, and the microprocessor determines the type of the brush head or other accessories corresponding to the received signal, so that the driving circuit is controlled to drive the motor to work, and meanwhile, the buzzer is controlled to carry out matching to complete confirmation prompt. The multifunctional application of the brush head or other accessories is met, and the multiple functions of the brush head or other accessories are enriched.

Description

technical field [0001] The invention relates to a brush head or other accessories recognition system. In particular, it relates to a recognition system and method for a brush head or other accessories based on a Hall device. Background technique [0002] The field of automatic identification technology is one of the main contents of modern information technology. Information technology includes physical signal, electrical signal technology and sensor technology. Automatic identification technology is widely used in the combination of components in electric toothbrushes. Most of the existing brands are based on the more complex automatic identification technology of NFC and RFID, such as Philips The company's RFID patented technology, however, ignores simple and applicable technological innovations. The use of circuit resistance detection is often faster, more convenient, simpler to calculate, easier to achieve detection control, and stable detection. [0003] About the ind...

AI Technical Summary

Problems solved by technology

[0006] At present, in the automatic identification technology of electric toothbrush heads or other accessories, there are certain similar products in the non-contact type, but the cost is relatively high, and the products in the same industry are all based on the high-cost NFC technology.
