Abstract
A ping-pong myopia prevention and treatment instrument can simulate the motion trail of a ping pong to generate the effect of preventing and treating myopia by playing the ping pong, has good effect and convenience in use, and comprises an instrument base, a tapered spring, an iron circular casing, a laser diode, a coil assembly, a controller and a battery, wherein the iron circular casing is mounted at the front end of the tapered spring, the laser diode is mounted in the iron circular casing, and all coils of the coil assembly surround the periphery of the iron circular casing uniformly.
Description
Technical field
This utility model relates to a kind of instrument for prevention and cure of myopia.
Background technology
Current, the instrument for prevention and cure of myopia on the market, its principle mainly is with physical method indirect action eyeball, offsets near reflex with optical means, improves the combination of eye movement sensitivity or these methods with the optics physical method.Practice, these method effects are all limited, and very limited with physical method indirect action eyeball effect, other method is used very inconvenient.
Summary of the invention
The purpose of this utility model just provides a kind of table tennis instrument for prevention and cure of myopia, and is not only effective, and easy to use.
The technical solution of the utility model is: the table tennis instrument for prevention and cure of myopia comprises instrument stand, volute spring, ferrum circle shell, laser diode, coil groups, controller, battery.Volute spring is installed on the instrument stand, ferrum circle shell is installed in the volute spring front end, laser diode is installed in the ferrum circle shell, each coil of coil groups is installed on the instrument stand, evenly be centered around ferrum circle shell around, the iron core in the coil is towards the center of ferrum circle shell, coil and ferrum circle shell are contour, the pin of laser diode is connected on the controller, and each coil of coil groups is connected on the controller, and the two poles of the earth of battery are connected on the controller.During use, under the effect of the program that controller sets in advance, each coil of coil groups produces suction by instruction, the pulling laser diode rotates according to certain rules, moves, and the hot spot of laser diode projection also rotates thereupon, moves, and human eye is along with hot spot rotates, the rotation of the rotation of human eye when playing table tennis is similar, because a large amount of fact proved, play table tennis and may prevent and treat myopia, can produce the effect of the similar control myopia of playing table tennis.
After adopting such structure, the rotation of the rotation of human eye when playing table tennis is similar, and control myopia is effective, and this table tennis instrument for prevention and cure of myopia need not be worn on the eyes, and small volume and less weight, and is easy to carry, in all case can use, very convenient.
