The utility model has the advantages of simple structure and attractive appearance, can be matched with a TV or a computer for use, and can effectively prevent a user from getting too close to the TV or the computer, so as to prevent myopia and protection the vision.
Description
Technical field
The utility model belongs to the household electrical appliances support equipment, specifically is a kind of myopia prevention suggestion device.
Background technology
Myopia is a kind of common eye disease; The reason that forms myopia is a lot, and in the teenager, the one of the main reasons that forms myopia is to see TV for a long time and play computer; And qn eye distance TV or computer display screen excessively closely cause; In a single day this custom is formed, and just is difficult to change, and has caused myopia.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of myopia prevention suggestion device.
A kind of myopia prevention suggestion device; It is characterized in that comprising shell; Said shell is provided with infrared inductor, loudspeaker and switch; Enclosure is provided with control circuit board and power supply, and said power supply and infrared inductor, switch, control circuit board are connected in series, and said control circuit board is connected with loudspeaker.
Described myopia prevention suggestion device is characterized in that said power supply is a battery.
Described myopia prevention suggestion device is characterized in that said shell is columniform.
The myopia prevention suggestion device of the utility model, simple in structure, handsome in appearance, can cooperate TV or computer to use, effectively prevent to have prevented myopia, vision protection apart from TV or computer hypotelorism.
Description of drawings
Fig. 1 is the synoptic diagram of the myopia prevention suggestion device of the utility model;
Fig. 2 is the circuit diagram of the myopia prevention suggestion device of the utility model;
Among the figure, 1-shell; 2-infrared inductor; 3-switch; 4-loudspeaker; 5-control circuit board.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As depicted in figs. 1 and 2; A kind of myopia prevention suggestion device of the utility model; Comprise cylinder blanket 1, shell 1 is provided with infrared inductor 2, loudspeaker 4 and switch 3, shell 1 set inside control circuit board 5 and power supply; Power supply and infrared inductor 2, switch 3, control circuit board 5 are connected in series, and control circuit board 5 is connected with loudspeaker 4.Power supply can be that battery also can be an external power supply.The distance of reaction of infrared inductor 2 can be provided with as required, and TV generally is about 3 meters, and computer generally is 0.5 meter, and getting into this distance as the people will be responded to.
During use; Can this myopia prevention suggestion device be positioned near TV screen or the computer monitor; If see TV or too near with the distance of computer, will be by infrared inductor 2 inductions, infrared inductor 2 passes to control circuit board 5 with signal; Control circuit board 5 control loudspeakers 4 sound that gives the alarm, the prompting hypotelorism.At this time adjust distance, surpass beyond the distance of reaction, infrared inductor 2 inductions disappear, and stop to transmit signal and give control circuit board 5, and alarm stops.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection domain of the utility model.
