Problems solved by technology

[0003] The cost of existing wireless charging products is very high, especially the price of the charging board is expensive, which is often more than 100 yuan, which has a negative effect on the further promotion and development of wireless charging technology. If a lower-cost wireless charging product can be developed, it will benefit wireless Further promotion and development of charging technology

[0004] After searching the patent database, the inventor found that the invention patent with the application number 201410065211.3 named "a wireless charging and discharging circuit, terminal equipment and wireless discharging method" is the technology closest to the present invention. Due to the design restrictions of the 201410065211.3 patent ( or limit of thinking), the inventor has adopted two relays with two branches to switch the connection between the receiving circuit and the transmitting circuit to the coil, so as to realize the sharing of a coil between the transmitting circuit and the receiving circuit; the relay is used as an electronic switch in many Among the electronic components, they are expensive and fragile components, with short life and high price, and there is room for improvement
