Wireless charging device and electronic candle lamp with same

Abstract

The invention provides a wireless charging device and an electronic candle lamp with the same. The wireless charging device comprises a transmitting module and multiple receiving modules, wherein the transmitting module comprises a power supply module, a fission circuit, a transmitting antenna, a transmitting control unit and a signal demodulation circuit; the transmitting antenna is of a rectangular shape; each receiving module comprises a receiving antenna, a rectifying circuit, an energy storage module, a receiving control unit, an electric appliance connected with the receiving control unit and a signal modulation circuit; each receiving antenna is a cylindrical spiral coil; the projection of each receiving antenna is completely positioned in the rectangular area of the transmitting antenna, and an energy transfer method for multiple electromagnetic induction receiving devices by single electromagnetic induction transmitting device is realized; and moreover, the electromagnetic induction transmitting device has uniform electromagnetic field distribution and good charging stability.

Description

technical field [0001] The invention relates to a wireless charging device and an electronic candle lamp with the device. Background technique [0002] With the development of wireless charging technology today, as more and more companies join in, the competition has become more and more fierce, especially for industry standards. The current mainstream wireless charging standards mainly include: PowerMattersAlliance (PMA) standard, Qi Standard and Alliance for Wireless Power (A4WP) standard, etc., each standard has its own advantages and disadvantages, and also has its own supporters. [0003] Since the advent of electronic candles, their use safety, convenience, energy saving, and environmental protection are being liked by more and more people, especially in European and American countries, and gradually have a tendency to replace traditional life-fire stick candles.

Problems solved by technology

[0003] Since the advent of electronic candles, their use safety, convenience, energy saving, and environmental protection are being liked by more and more people, especially in European and American countries, and gradually have a tendency to replace traditional life-fire stick candles. Electronic candles in the prior art are generally The charging interface is used for charging. This charging method will cause serious wear and tear on the charging interface after a long time, and finally lead to failure to charge. Most of the electronic candles on the market use a single switch to open the mode, which has a single function and is not competitive

[0004] By combining the above two technologies, a wireless charging electronic candle is produced, but the wireless charging electronic candle in the prior art is usually only charged in a one-to-one manner, that is, one transmitting antenna corresponds to one receiving antenna, such as CN 203836826 U, discloses a multi-induction wireless charging candle. When using this technology, multiple electronic candles cannot be charged at the same time, such as US2007 / 0223217A1. Although this technology discloses a one-to-many charging method, the principle of its application is still A transmitting antenna corresponds to a receiving antenna, which only increases the number of transmitting antennas in the charging base. For this technology, the charging base is relatively large in size and uses multiple transmitting antennas, which is extremely inconvenient to control and greatly improves manufacturing cost
