Description
Technical field
The present invention relates to wireless charging technical field more particularly to a kind of radio energy emission system and the fresh-keeping dresses of electrostatic wave
It sets.
Background technique
Wireless power transmission, also known as wireless power transmission or transmitting non-contact electric energy refer to through specific transmitter
The relaying energy (such as electromagnetism field energy, laser, microwave and mechanical wave) for converting electrical energy into other forms is launched, then passes through
Specific receiver is converted to electric energy for energy is relayed, and realizes wireless power transmission.
According to the difference for relaying form of energy in energy transport, wireless power transmission can be divided into: magnetic (field) manifold type,
Electric (field) manifold type, electromagnetic radiation formula (such as solar radiation), mechanical wave manifold type (ultrasound).Wherein, magnetic coupling type is current (21
Beginning of the century) a kind of research wireless power transmission mode burning the hotest, that is, high frequency electric source is loaded into transmitting coil, make to send out
Ray circle generates high frequency magnetic field under power supply excitation, and receiving coil generates couple current, under the effect of this high frequency magnetic field with this reality
Existing wireless power transmission.
Nowadays, more and more electronic products bring great convenience for the Working Life of people, but traditional electric power
Transmission mode is by conducting wire or socket mostly by power transmission to end product.With mobile device, wireless data transmission, nothing
Line network technology becomes increasingly popular, and it is desirable to get rid of the constraint of conventional electric power transmission mode, releases numerous and disorderly power supply line and brings
Puzzlement.Wireless power transmission technology becomes 21 century technology most worthy of expecting as a result, and the product that wirelessly conducts electricity is closed as people
The new focus of note.
Wireless power transmission technology does not generate radiation, and safety has passed through the standard authentications such as FCC, IEEE and CCC, no
Danger will not only be generated, it is thus also avoided that the equiprobable security risk such as hot plugging, power supply line short circuit.Before ensuring safety
It puts, wireless power mode can thoroughly solve that room wiring is in disorder, arrester location is fixed, socket destroys house fitting etc.
Problem, it is more convenient and beautiful to bring to our life.Importantly, wireless power saves a large amount of wire rod, no matter
Be the metals such as rubber, plastics or copper, tin consumption all will therefore and be greatly reduced, economize on resources, reduce pollution, low-carbon ring
It protects.
Wirelessly conduct electricity product, especially low power class product, effective propagation path on the market is very limited at present, is needed
Want emitter to fit to radio energy reception device just can be carried out electric energy transmission together.When radio energy reception device once
Radio energy emitter (more than 3mm distance) is left, electric energy just stops transmitting.This kind conducts electricity mode, can not real meaning do
It can only be known as contactless power transfer (Contactless Power (compared with wireless router or WIFI) to wireless
Transfer).Compared to original wired mode transmission (range that conducts electricity is using socket as the center of circle, and transmission line is the sphere of radius),
The product (range that conducts electricity is to be wirelessly transferred one point of emitter) that wirelessly conducts electricity at present loses the spy much having originally instead
Point, and have no advantage.
