Description

A pen that protects eyesight

Technical field:

The utility model relates to a pen, in particular to a pen with the function of protecting eyesight. This pen can remind people at any time of the distance between the eyes and the book when writing. When the distance is too close, an alarm on the pen will give an alarm to remind people to adjust their sitting posture and increase the distance between the eyes and the book. Prevent myopia and protect eyesight.

Background technique:

With the development of society, our life pressure is also increasing. In the final analysis, the 21st century is the competition of knowledge, so learning has become an important part of life. Whether you are a student or an adult who has entered the society, if you want to If you don't fall behind in this society, you have to study and recharge frequently.

In view of the above reasons, it is necessary for us to have a device for protecting eyesight of the utility model. Because the pen is an essential utensil when writing, if the pen can be improved to play the effect of protecting eyesight, it will be a very useful help to the society.

Utility model content:

The purpose of the utility model is to provide a pen for protecting eyesight. Because there is a device for protecting eyesight in this pen, it can remind people at any time when writing, the distance between the eyes and the book, so as to prevent myopia or vision loss.

In order to achieve the above object, the technical solution of the utility model is:

A pen for protecting eyesight, comprising a main body, the main body includes a pen holder and a refill, and is characterized in that the main body also includes a height measuring instrument, and the height measuring instrument is connected to a signal processing device, and the signal processing device is connected to A control circuit, the control circuit is connected with an alarm.

The signal processing device includes a signal processor.

The height measuring instrument, signal processor, control circuit and alarm are all arranged in the penholder.

Beneficial effects: the utility model is a pen for protecting eyesight, which can always remind people to pay attention to adjusting sitting posture when reading a book, so as to protect eyesight, and has a simple structure, is convenient and practical.

Description of drawings:

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a structural block diagram of the utility model.

Detailed ways:

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

With reference to Fig. 1, comprise height measuring instrument 1, signal processing device 2, control circuit 3, alarm 4 among the figure, height measuring instrument 1 is used for measuring the vertical height of people's head distance desk, height measuring instrument 1 and signal processing device 2 connected, the altimeter 1 compares the measured height value with the standard value stored in the signal processing device 2, when the measured height is greater than the standard value, the signal processing device 2 will send out a signal and transmit the signal In the control circuit 3, the control circuit 3 will perform an action according to this signal, and control the alarm 4 to send an alarm, thereby reminding people to adjust their sitting posture and increase the distance between the eyes and the desk. If the height measured by the altimeter 1 is less than the standard value stored in the signal processing device 2, the signal processing device 2 will not send a signal, so the control circuit 3 will not control the alarm 4 to send an alarm signal.

When the utility model is made, the circuit connected by the height measuring instrument 1, the signal processing device 2, the control circuit 3 and the alarm device 4 can be set in the penholder or on the top of the penholder, so that it is convenient to use and can To achieve the purpose of measuring the distance between the person's head and the desk.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above.
