Abstract
The utility model discloses a portable wireless charger. The portable wireless charger is internally provided with a storage battery for storing power, is capable of wirelessly charging a terminal electrical appliance without connecting with an external power source, and is provided with two coils. One of the two coils is a receiving coil which is used for charging the storage battery in a wireless charging mode, and the other is a sending coil which is used for generating electromagnetic fields to wirelessly charge the terminal electrical appliance. Besides, the portable wireless charger is provided with a charging interface, and can be charged through a power cord. By the aid of the internal storage battery, the portable wireless charger can be used for charging the terminal electrical appliance after disconnected with the power source; and the internal storage battery can be charged both in a wired mode and a wireless mode.
Description
Technical field
The utility model relates to appliance field, particularly a kind of portable wireless charger.
Background technology
As everyone knows, battery charge such as various portable electric appts such as mobile phone, flat boards is a headachy thing, also need to seek suitable socket except needing because of different electronic products during charging the practical different chargers, use very inconvenient.Therefore, a kind of wireless charger has appearred on the market.The profile of wireless charger is as the electromagnetic stove table top, inside arranges the induction type coupling that can produce the certain frequency electromagnetic field after the energising and loses, and can respond to this electromagnetic inductive energy the electronic equipment setting of needs charging, and be converted into electric energy, finish charging process.But this kind wireless charger intelligence could be charged to wireless terminal device by connecting power supply, just can't charge to wireless terminal device when having a power failure, travelling or not connecting power supply, has caused certain restriction for actual the use.
The utility model content
In order to overcome above-mentioned shortcoming, the purpose of this utility model is to provide a kind of portable mobile wireless charger.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of portable mobile wireless charger, described portable mobile wireless charger includes receiving coil, send coil, control circuit, charging inlet and storage battery, described storage battery links to each other with control circuit, described receiving coil connects control circuit, receiving coil receives electromagnetic energy, charge a battery by control circuit, described charging inlet connects control circuit, charging inlet is connected to power supply, charge a battery by control circuit, described transmission coil connects control circuit, and control circuit control storage battery transmits electric energy to sending coil, sends electromagnetic energy by sending coil again.
The line of described transmission coil and receiving coil directly is 0.3mm～0.6mm, and coil turn is 12～18 circles.
Technical conceive of the present utility model is: the portable mobile wireless charger built-in has the storage battery of storage of electrical energy, can leave under the situation of external power supply, still can carry out wireless charging to terminal appliance, this charger also has been equipped with twin coil simultaneously, one is receiving coil, is used for charging for the storage battery of this programme by the wireless charging mode; Another for generation of electromagnetic field, carries out wireless charging to terminal appliance for sending coil, and this programme also has a charging inlet simultaneously, can charge to this programme by power line.
The beneficial effects of the utility model mainly show: 1, internal battery, can still can carry out wireless charging to terminal appliance after breaking away from power supply; 2, can give built-in charge in batteries by wireless and wired dual mode.
Description of drawings
Content of the present utility model is easier clearly to be understood in order to make, according to specific embodiment of the utility model also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is the structural representation of portable mobile wireless charger of the present utility model;
Fig. 2 is the application principle schematic diagram of portable mobile wireless charger of the present utility model.
Embodiment
With reference to Fig. 1～Fig. 2, a kind of portable mobile wireless charger, described portable mobile wireless charger includes receiving coil, send coil, control circuit, charging inlet and storage battery, described storage battery links to each other with control circuit, described receiving coil connects control circuit, receiving coil receives electromagnetic energy, charge a battery by control circuit, described charging inlet connects control circuit, charging inlet is connected to power supply, charges a battery by control circuit, and described transmission coil connects control circuit, control circuit control storage battery transmits electric energy to sending coil, sends electromagnetic energy by sending coil again.
The line of described transmission coil and receiving coil directly is 0.3mm～0.6mm, and coil turn is 12～18 circles.
With reference to shown in Figure 2, the internal battery of portable mobile wireless charger can be realized batteries to store energy by wireless and wired two kinds of charging modes, wireless charging is by built-in receiving coil, receiving coil sends the electromagnetic wave that power supply sends by receiving other wireless charger wireless charging, receiving coil converts electromagnetic wave to electric energy, by control circuit with electrical power storage in storage battery; Wired charging directly inserts charging inlet with external power source by the mode that is electrically connected by built-in charging inlet, thereby accumulators provides the electric energy charging.After storing certain electric energy for the portable mobile wireless charger, the user can not have under the situation of mains supply in power failure, travelling etc., uses portable charger to carry out wireless charging for the terminal appliance that possesses the wireless charging receiving function.
Though the utility model is described with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment illustrates the utility model; should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense; so be not that conduct is to restriction of the present utility model; as long as in connotation scope of the present utility model, to the variation of the embodiment under above, the protection range that distortion all will fall into the utility model claim.
