Abstract
Provided is a minisize laser wireless charging teaching rod, comprising a teaching rod and a charging seat. The teaching rod comprises a handle, a basic rod, an expansion link, and a rod cap. The handle is a hollow teaching rod holding end. The handle is provided with a receiving coil, a receiving control circuit, a charging battery, and a mini laser device which are electrically connected. A housing of the handle is connected with the hollow basic rod. The basic rod is connected with the hollow expansion link, and the other end of the expansion link is provided with the transparent rod cap. The charging seat comprises a mounting base and a hollow teaching rod fixing seat connected with the mounting base. Inside of the teaching rod fixing seat is provided with a power adapter, an emission control circuit and an emission coil which are electrically connected. The bottom of the teaching rod is provided with a wireless charging coil. After class, the teaching rod is put on the teaching rod seat to be charged, ensuring the teaching rod would not be unable to emit light since battery is dead, and meanwhile wireless charging does not need an interface or a connecting line, so appearance of the teaching rod is smooth, and structure is firm.
Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of miniature laser wireless charging teaching pole.
Background technology
Teaching pole is teacher's one of conventional instrument in teaching, and traditional teaching pole is due to limited length, during teaching from teacher's health away from and higher giant-screen or the word on blackboard, figure often occur beyond one's ability to help; Occurred now the teaching pole with miniature laser, can address this problem, but the teaching pole of miniature laser usually needs to change battery now, causes the many troubles in use procedure.
Utility model content
The purpose of this utility model is: a kind of miniature laser wireless charging teaching pole is provided.
In order to achieve the above object, the scheme adopting is: a kind of miniature laser wireless charging teaching pole, comprise teaching pole and cradle, and described teaching pole comprises handle, base bar, expansion link and pole cap; Described handle is that hollow teaching pole is held end, is provided with receiving coil, reception control circuit, rechargeable battery and the miniature laser transmitter of electrical connection in handle; The shell of handle is connected with hollow base bar, and base bar connects hollow expansion link, and the other end of expansion link is provided with transparent pole cap; Described cradle comprises the hollow teaching pole holder of mount pad and connection seat, the inside of teaching pole holder is provided with power supply adaptor, countdown circuit and the transmitting coil of electrical connection, power supply adaptor is provided with the attaching plug stretching out, in transmitting coil, be provided with iron core, one end of teaching pole holder is provided with recess.
Adopt the beneficial effect of such scheme to be: in teaching pole bottom, be provided with Wireless charging coil, lower class hour will be teaching pole charging by teaching pole folding and unfolding to teaching pole seat, and assurance teaching pole of upper class hour can not sent out because of dead battery not bright dipping; Meanwhile, wireless charging does not have interface, there is no connecting line, makes teaching pole smooth in appearance, firm in structure.
