Description

technical field [0001] The invention relates to the field of charging equipment, in particular to a wireless charging equipment. Background technique [0002] With the development of science and technology, there are more and more portable electronic products such as mobile phones, MP3 players, digital cameras and notebook computers. At present, the charging of these devices is mainly adopted: one end is connected to a power frequency AC power supply, and the other end is connected to a traditional charging method of a rechargeable battery of a portable electronic device. This charging method has many disadvantages. First of all, frequent plugging and unplugging can easily damage the connector, and it may also bring the risk of electric shock. Also, because there are many types of electronic products, each product has its own charger, which is incompatible with each other, and it is inconvenient to carry it with you. [0003] Some researches have been done on wireless char...
