A writing pen anti-myopia device

Abstract

The invention belongs to the technical field of manufacturing of stationery, and relates to a shortsightedness-preventing device of a writing pen. A fixed pen cap, an insulation box, a metal ring, a battery, a pressure spring, a vibration motor, a loudspeaker and a light emitter are sequentially manufactured in an inner cavity of a shell body of a cylinder structure from bottom to top. The light emitter is manufactured at the top end of the shell body. A control panel is manufactured on the side face of the shell body. Buttons are arranged on the control panel. The fixed pen cap is manufactured in the inner cavity at the bottom of the shell body. The insulation box inserted in the shell body is filled with conductive liquid. The vibration motor and the loudspeaker are manufactured in the inner cavity at the top of the shell body. The pressure spring is manufactured at the lower end of the light emitter. The upper end of the metal ring is in butt joint with the battery. The lower end of the metal ring is arranged on the insulation box in a butt joint mode. The shortsightedness-preventing device is simple in structure principle, low in manufacturing cost, flexible in cooperative use, capable of realizing full control or simplex control over an alarm circuit and flexible in control.

Description

Technical field: [0001] The invention belongs to the technical field of preparation of learning tools, and relates to a writing pen anti-myopia device for students, in particular to a writing pen anti-myopia device combined with physical principles and electrical components. Background technique: [0002] At present, the learning burden of primary and middle school students is generally too heavy, and students spend more time writing. Among them, students often use the writing pen incorrectly due to posture or seat equipment when writing, especially primary school students, and those in rural areas Due to the lack of conditions for the home study environment, it is difficult for students to ensure the normal use of lights and seats, so it is more likely to cause the wrong state of holding the writing pen when studying and writing homework, which has a great impact on myopia and physical condition. The posture of the pen has a great influence on the vision of the writer, espe...

[0002] At present, the learning burden of primary and middle school students is generally too heavy, and students spend more time writing. Among them, students often use the writing pen incorrectly due to posture or seat equipment when writing, especially primary school students, and those in rural areas Due to the lack of conditions for the home study environment, it is difficult for students to ensure the normal use of lights and seats, so it is more likely to cause the wrong state of holding the writing pen when studying and writing homework, which has a great impact on myopia and physical condition. The posture of the pen has a great influence on the eyesight of the writer, especially in the state of low light, the posture of holding the writing pen is more likely to affect the health of young students

In order to solve this situation, many anti-myopia pens, anti-myopia brackets, anti-myopia desks and anti-myopia bookshelves etc. have been released for the prevention of myopia for primary and middle school students, but these existing anti-myopia devices have a single structure and cannot be used. The range is small, often only one structure is matched with the pen, it is not flexible to use, and the warning function is single, and the combination of optical, acoustic and vibration functions cannot be used together. Therefore, a new structure with multiple warning functions is developed and researched. Writing pen anti-myopia device has great application prospects and economic value
