Abstract
The utility model relates to a wireless charger, which comprises primary coils connected to an AC power supply circuit, and secondary coils which produce induced electromotive force by inducing the magnetic field change of the primary coils, wherein the secondary coils are integrated in a portable electronic device and serves as power supply coils to be connected with a charging circuit in the portable electronic device. The utility model has novel design, safety and environmental protection because of completely overcoming the defects that the existing charger adopts a plug and socket form, very convenient use because of charging a plurality of or various electrical equipment simultaneously, low stand-by loss, high work efficiency and low heat productivity.
Description
Technical field
The utility model relates to a kind of charger, specifically a kind of wireless charger.
Background technology
Along with people's growth in the living standard day by day, ease of use and environmental requirement to electrical equipment are also more and more higher, day by day gradually Duo various portable electronics equipment cause the existence of a large amount of different size chargers, and these electronic products are in case upgrade or do not re-use, and the pollution of environment be can not be ignored.Charger except specification different multifarious and also individual characteristics are all arranged is exactly to want the stube cable line, except the not convenient property of using, the repeatedly plug of plug makes its electrical contact performance bad easily, and shortcomings such as dust and sweat are easily advanced at the plug place of electrical equipment, copper that plug itself contains and human body are contacted many also are corroded easily and infiltrate human body, health is caused harmful effect, and itself also influenced in useful life.
The utility model content
The technical problems to be solved in the utility model provides a kind of wireless charger easy to use, safe in utilization.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of wireless charger, comprise that the primary coil and the inductive primary coil magnetic field that are connected in the ac power supply line change the secondary coil that forms induced electromotive force, described secondary coil is integrated in the portable electric appts, is connected with charging circuit in the portable electric appts as the power supply coil.
As the improvement to such scheme, above-mentioned primary coil is sealed in the waterproof case.
In waterproof case, be set side by side with one or more can be to the primary coil of multiple portable electric appts charging.
The utility model modern design has been eliminated the defective that existing charger adopts plug, socket type fully, and safety, environmental protection can be charged to a plurality of, multiple power consumption equipment simultaneously, and be very easy to use.And idling consumption is little, high efficiency, and it is little to generate heat.
Description of drawings
Accompanying drawing 1 is the present embodiment structural representation;
Accompanying drawing 2 is the utility model embodiment fundamental diagram.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in Figure 1, the wireless charger that present embodiment discloses has utilized electromagnetic induction principle, has adopted totally enclosed form to realize that energy shifts safety, environmental protection.
This wireless charger comprises that the primary coil 1 and the inductive primary coil magnetic field that are connected in the ac power supply line change the secondary coil 2 that forms induced electromotive force, described secondary coil is integrated in the portable electric appts, is connected with charging circuit in the portable electric appts as the power supply coil.
Have waterproof, pollution-free, safe effect in order to reach charger, primary coil 1 is sealed in the waterproof case 3.
In order to charge to a plurality of, multiple portable electric appts simultaneously, described primary coil is provided with a plurality of, is set up in parallel in waterproof case 3.
As shown in Figure 2, primary coil 1 is connected with electric main, does the magnetic field that the respective electric conversion changes by control circuit, is arranged in secondary coil 2 induced fields of portable electric appts and forms induced electromotive force electronic equipment is charged.
From the above, the utility model is the outstanding example that this theory of electromagnetic induction principle is used in actual life, has greatly increased the facility of people's lives.In addition, need to prove that the foregoing description only is the preferable implementation of the utility model, and indefiniteness is exhaustive, in any conspicuous replacement that does not break away under the present utility model design prerequisite, all within the utility model protection range.
