Description

Portable eyesight protection device

Technical Field

The utility model relates to the field of articles for daily use, in particular to portable eyesight protection device.

Background

Wearing glasses only helps people with poor vision to provide vision correction function, and cannot remind people wearing glasses of poor eye posture, and the vision is further reduced due to incorrect sitting posture and wrong reading posture.

In order to solve the technical problem, chinese patent No. CN 202083847U discloses a pair of novel distance measuring glasses, including a frame and lenses, the lenses are fixedly mounted on the frame, the front middle position of the frame, namely, a distance sensor is fixedly mounted at the position between the two lenses, the distance sensor is communicated with an audible alarm device, although the novel distance measuring glasses can timely and effectively prompt a user to correct the eye posture, so as to protect the eyesight, the eyesight is degraded, besides the incorrect eye posture, the most important eye fatigue is caused by long-time use of eyes, so the distance measuring glasses also have the following defects: only play the role of prompting the wrong eye using distance, when the wearer uses the eyes for a long time, the user does not prompt, and the eye using posture and the eye using time only take one into account, so that the effect of protecting the eyesight is not good.

SUMMERY OF THE UTILITY MODEL

Therefore, in view of the above problems, the present invention provides a portable eyesight protection device with simple structure, low production cost and eyesight protection.

In order to realize the technical problem, the utility model discloses the solution that takes is portable eyesight protection device, including the mirror holder, set up the distance induction system who lies in the middle of the picture frame on the mirror holder and the sound alarm device who lies in the mirror leg, be provided with the audio frequency on the mirror holder and report the device, be provided with the music chip of typing in the suggestion audio frequency in the mirror holder and have the controller that timing control music chip opened the shutdown function.

The further improvement is that: the audio broadcasting device comprises an earphone, a through groove is formed in the spectacle frame along the axial direction, a connecting wire of the earphone can be pulled and arranged in the through groove, and a signal input end of the earphone is connected with an output end of the music chip.

The further improvement is that: the distance sensing device is an optical sensor, the sound alarm device is a buzzer, the signal output end of the optical sensor is connected with the input end of the controller, and the signal input end of the buzzer is connected with the output end of the controller.

The further improvement is that: still include temperature sensor, temperature sensor set up in the position of contact with the auricle on the mirror holder, temperature sensor's signal output part with the input of controller links to each other.

By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model discloses set up the earphone of pull in the mirror leg built-in music chip that has recorded eye exercises audio frequency and on the mirror leg, when using eye time for too long, will automatic play eye exercises audio frequency in the earphone, the suggestion user should stop using the eye, has played the effect that prevents asthenopia, can protect eyesight, prevention myopia.

Further, the method comprises the following steps: the utility model discloses set up temperature sensor with the position of auricle contact on the mirror leg to set up the singlechip in the mirror leg, thereby utilize the difference of human body temperature and room temperature to open the timing function of singlechip and confirm the signal break-make of music chip, prevented when the user does not use this eyesight protection device, its audio frequency of broadcast by oneself, more power saving.

Drawings

Fig. 1 is a schematic structural view of the portable eyesight protection device of the present invention.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, disclosed in an embodiment of the present invention is a portable eyesight protection device, including a frame 1, the frame 1 includes a frame and two legs, a single chip microcomputer (not shown) is disposed on the frame 1, an optical sensor 2 is disposed on the frame 1 at the middle portion of the frame, a buzzer 21 is disposed on the left leg of the frame 1, a signal output terminal of the optical sensor 2 is connected to an input terminal of the single chip microcomputer, a signal input terminal of the buzzer 21 is connected to an output terminal of the controller, when the optical sensor 2 senses that a distance to a front object is lower than a set value, the single chip microcomputer sends an on signal to the buzzer 21, the buzzer 21 sends an alarm until the distance to the optical sensor 2 from the front object is higher than the set value, the single chip microcomputer sends an off signal to the buzzer 21, buzzer 21 stops the alarm, two one side of pressing close to the human body on the mirror leg is provided with earphone 3, two logical groove (not shown in the figure) has been seted up along the axial in the mirror leg, but earphone 3's connecting wire pull set up in logical inslot, still be provided with the music chip (not shown in the figure) of type eye exercises audio frequency in the mirror leg, earphone 3's signal input part with music chip output end links to each other, the signal output part of singlechip with the signal input part of music chip is connected, the position with auricle contact on the mirror leg still is provided with temperature sensor, temperature sensor's signal output part with the input of singlechip links to each other, still be provided with the lithium cell (not shown in the figure) that provides electric power for this vision protection device in the mirror leg.

When a user wears the eyesight protection device, the glasses frame 1 and the earphones 3 are worn, temperature sensors on the glasses legs sense temperature changes due to the fact that the body temperature is different from the room temperature, when the temperature sensed by the temperature sensors is 35-40 degrees, a preset countdown program in the single chip microcomputer starts, after 50-minute countdown is finished, the single chip microcomputer transmits an on signal to the music chip, the music chip starts, audio of the eye exercises is transmitted from the earphones 3, the user can pick off the glasses frame 1 at the moment, the user wears the earphones 3 to conduct the eye exercises along with the audio, the user can also choose to take off the eyesight protection device to overlook a distant place and relax eyes, the glasses frame 1 can be worn again after the audio is played, and the timer can count down again.

Having shown and described the basic principles and essential features of the invention and its advantages, it will be understood by those skilled in the art that the present invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but is susceptible to various changes and modifications without departing from the spirit and scope of the invention, all of which are intended to be covered by the appended claims and their equivalents.
