Wireless electric energy transmitting device and wireless electric energy power supply system

Abstract

The invention discloses a wireless electric energy power supply system comprising a wireless electric energy transmitting and receiving device. According to the system, electric power is transformed into an electromagnetic field to carry out electric energy transmission, so that electric energy is used for power supply in a wireless mode. A wireless electric energy transmitting terminal comprises a heat dissipation module and a switch control module used for remotely controlling the system to be turned on and off, and a wireless electric energy receiving terminal is provided with a shielding module which can be used for effectively shielding the electromagnetic field. The system disclosed by the invention has a better heat dissipation effect, the service life of the system is prolonged, and through the shielding of the electromagnetic field, internal components of an electric appliance can be protected against electromagnetic interference so as to ensure the normal working of the electric appliance, and the stability of the whole system is improved.

Description

Technical field [0001] The present invention relates to wireless power technology, in particular to a wireless power transmitting device with good heat dissipation effect; [0002] The invention also relates to a wireless power supply system that can prevent the components in the electrical appliance from being affected by electromagnetic interference. Background technique [0003] At present, in people’s daily life, the mainstream power supply method for household appliances (such as rice cookers, mixers, etc.) is still through wired power supply, while the wired power supply method must be surrounded by wires (such as in the room). Lines are arranged on the walls of the wall), which will increase the inconvenience of use, and the wired method requires the use of sockets, which increases the restrictions on the use of electrical appliances. [0004] In order to avoid the inconvenience caused by wired power transmission, people continue to devote themselves to the research of wirele...

Problems solved by technology

However, in the prior art, since the wireless power transmission device is used for the transmission of high-power electric energy, a large amount of heat energy will inevitably be generated at the transmitter end, and long-term use may easily cause potential safety hazards in the use of the power transmission device

In addition, since the power receiving end of the wireless power supply system is in the package of the electromagnetic field, this will cause the internal components of the load electrical appliance to be affected by electromagnetic interference. Long-term use will inevitably affect the normal operation of the internal components, and ultimately directly affect the service life of the electrical appliance.
