Problems solved by technology

However, although the current wireless charging technology frees people from the shackles of charging cables, each device is independent of each other and not universal
When using multiple wireless charging devices, a table full of chargers can also make the home very cluttered
Moreover, at this stage, wireless charging technology is still concentrated on high-end devices of a few brand products, and its high price makes this technology not yet fully popularized.

Abstract

The invention discloses a wireless charging protection sleeve, and the protection sleeve comprises a protective sleeve, a receiving end circuit, a connection circuit, a charging port and an adjustment switch which is used for controlling and adjusting the receiving end circuit. The receiving end circuit is fixedly disposed at an inner side of the protective sleeve, and the exterior of the receiving end circuit is provided with a flat protection housing. The receiving end circuit and the charging port are connected with each other through the connection circuit. The protection sleeve is simple in structure, is convenient to use, and can carry out the wireless charging of various types of electric appliances with different DC voltages.

Description

technical field [0001] The invention relates to the field of wireless charging systems, in particular to a wireless charging protective case. Background technique [0002] The current wireless charging devices on the market are all one-to-one wireless charging. To realize multiple wireless charging, multiple platforms are required for charging. Devices with wireless charging function, whether it is a mobile phone or a Bluetooth speaker, are often high-end flagship products among similar products and are expensive. Although some mobile phones and smart bluetooth speakers have relatively mature technologies, they are all independent and specific charging systems. [0003] Wireless charging technology was originally designed to free people from messy charging cables. However, although the current wireless charging technology frees people from the shackles of charging cables, each device is independent of each other and not universal. When using multiple wireless charging dev...
