The invention discloses a student sitting posture correcting and shortsightedness preventing alarm. The student sitting posture correcting and shortsightedness preventing alarm includes an alarm headand an alarm main body; the alarm main body is located under the alarm head, an ultrasound detection head is arranged on the front portion of the alarm head, and a loudspeaker is arranged on the rearportion of the alarm head; a photosensitive sensor detection head and a time and temperature display screen are arranged on the front portion of the alarm main body, and a direct-current power supplysocket is formed in the rear portion of the alarm main body. The student sitting posture correcting and shortsightedness preventing alarm is simple in structure and reasonable in design, through the cooperation of the ultrasound detection head and the photosensitive sensor detection head, on one hand, a user can be reminded to turn on a light under the condition of insufficient light, on the otherhand, the user can be reminded when it is detected that the distance between the body and a desk is smaller than a preset distance, and therefore health growth and good study habits of teenagers areensured.
Description
technical field [0001] The invention relates to the technical field of alarms, in particular to a student sitting posture correction anti-myopia alarm. Background technique [0002] Now students have been writing for a long time, and they will be tired and lie on the table to write. The eyes are too close to the books, which is easy to cause myopia, and at the same time lead to poor bone development.

At this time, students do not consciously turn on the lights, which will affect their eyesight in the long run. At the same time, if the light is too dark, in order to see the corresponding font clearly, the body will bend forward, which will affect the physical development and produce adverse consequences. Contents of the invention [0004] The purpose of the present invention is ...
