Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to an induction current energy consumption collection and charging device in a 220V50Hz loop. Background Art

[0002] In recent years, with the development of the Internet of Things and smart homes, various sensors and smart devices have been used more and more widely. However, these devices usually require independent power supplies, especially battery-powered devices, and their replacement or charging process brings additional operation and maintenance costs and environmental impacts. Existing wireless charging technologies are mainly concentrated in high-frequency and low-voltage scenarios, such as Qi standard electromagnetic induction charging and resonant wireless charging technology used in some electric vehicles. They achieve close-range energy transmission through dedicated transmitting and receiving coils. Despite this, there are relatively few technical solutions on the market for collecting induced currents generated by reactive losses or leakage magnetic fields from power supply circuits and converting them into effective electrical energy in ordinary household AC power grids (220V / 50Hz). In particular, this low-frequency and high-voltage induction energy generated during the operation of high-power electrical appliances has not yet been effectively captured and reused.

[0003] Although some patents such as CN204967641U and CN1578050A respectively introduce charging devices with voltage and current display functions and charging current detection circuits, they do not involve the functional design of directly collecting induced current from the mains circuit for energy recovery and wireless charging. In addition, although some studies have explored methods for obtaining electrical energy in a specific low-frequency AC environment, such as through improved rectification and filtering technologies, these technologies are generally not suitable for directly extracting and converting induced energy from high-voltage AC circuits. In terms of mobile phone wireless charging technology, although there are widely used wireless charging solutions such as the Qi standard on the market, such as wireless chargers with a power range of 5W to 15W achieved by the principle of electromagnetic induction, these products generally work in a high-frequency (kHz level) low-voltage environment, mainly providing charging services for low-power portable electronic devices. For example, the built-in receiving coil of a smartphone and the dedicated transmitting coil transfer energy through magnetic resonance or electromagnetic induction coupling, rather than directly extracting and converting induced current from a 220V / 50Hz high-voltage AC circuit.

[0004] Existing wireless charging technology is mainly aimed at low-power, low-voltage devices, such as mobile phones and wearable devices. There is little collection and utilization of inductive energy consumption in high-voltage, high-current home power supply circuits such as 220V / 50Hz, which is technically difficult, and safety and efficiency issues have not been effectively solved. Although the Qi standard and other standards have promoted the standardization of wireless charging, these standards are not applicable to the technical field of energy recovery from high-voltage AC lines, and lack unified design and implementation specifications. In high-frequency wireless charging, the overall energy efficiency is low because the electromagnetic field coupling efficiency is affected by many factors (such as distance, angle, coil design, etc.). In the 220V / 50Hz power frequency environment, how to ensure high efficiency and avoid interference or safety hazards to the power grid in the process of directly collecting induced current from the circuit and converting it into usable energy is a key challenge. Smart home sensors and other battery-powered devices usually require separate wiring for power supply or regular battery replacement, which increases construction costs and maintenance complexity.
