Intelligent identification fast charging power supply type heating control device for electric heating product

Abstract

The invention relates to an intelligent identification fast charging power supply type heating control device for an electric heating product, which comprises a key wake-up circuit, a power supply circuit, an output control circuit, a main control circuit supporting a QC fast charging protocol and a TYPE-C interface used for being connected with a fast charging power supply in a pairing way, wherein the TYPE-C interface is provided with a pin IN+, a pin IN-, a pin D+, a pin D- and a pin OUT1-, the pin IN+ is connected with the power supply circuit through the key wake-up circuit, the pin IN- is grounded, the pin D+ and the pin D- are connected with the main control circuit to complete handshake communication of a QC fast charge protocol with the fast charging power supply, and the pin OUT1- is connected with the output control circuit to perform fast charge on the heating load in a handshake communication state; and after handshaking succeeds, the fast charging power supply achieves fast charge for the heating load, the heating time is shortened, and then the heating efficiency is improved. Moreover, the fast charging power supply can be awakened to continue working by autonomouslyoperating the key, the fast charging power supply is prevented from entering a sleep state, the awakening process is autonomously operated, and the flexibility is high.

Description

technical field [0001] The invention relates to the technical field of heating control devices, in particular to an intelligent identification fast charging source type heating control device for electric heating products. Background technique [0002] Electric heating products (such as electric heating quilts, electric blankets, hot compress belts, etc.) are essential supplies in the cold winter. At present, the controllers of electric heating products on the market are difficult to quickly identify the fast charging source, which makes it difficult to quickly charge the heating load (higher DC voltage), resulting in long heating time and low heating efficiency. In addition, the existing fast charging source will enter a sleep state after working for a period of time, resulting in no output current. [0003] Therefore, in the patent application of the present invention, the applicant has meticulously researched an intelligent identification fast charging source type heatin...
