Intelligent shortsightedness prevention desk with bad sitting posture early warning function

Abstract

The invention belongs to the technical field of intelligent shortsightedness prevention for desks and particularly relates to an intelligent shortsightedness prevention desk with a bad sitting postureearly warning function. The desk comprises a desk body, the desk body comprises a writing platen with an adjustable inclination angle, a control device and an alarm device, supports which can be folded, unfolded and fixed are arranged at the bottoms of the two sides of the rear side of the writing platen, and a bookshelf is detachably installed at the rear end of the desk body; a table lamp witha bendable lamp neck and a distance phototube are arranged at the rear side of the writing platen. Compared with the prior art, the intelligent shortsightedness prevention desk has the advantages thata desk top with an adjustable inclination angle, the table lamp and the distance phototube are adjusted and comprehensively used, sitting posture correction or proper rest is reminded for a user, andthe function of effectively preventing shortsightedness can be achieved; a certain interaction function is also achieved, and the problem can be solved that when a student has a problem in learning,the problem is difficultly solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent anti-myopia tables, and in particular relates to an intelligent anti-myopia table with an early warning function for bad sitting posture. Background technique [0002] Among the students in our country, the number of myopia accounts for a very high proportion. Myopia seriously affects study, life and work. Due to the uneven distribution of educational resources in our country, there are great differences between schools. Both primary and middle school students want to be admitted to key middle schools. Students have a heavy academic burden and almost no time to play. Completing homework and extracurricular homework is the primary task every day. The time spent reading and writing is too long every day. The distance between the eyes and the desktop is too close. Long-term visual fatigue is the main cause of myopia.

Problems solved by technology

However, this kind of bracket placed under the chin makes primary and middle school students feel uncomfortable, unwilling to use it, buy it and don’t use it, and it doesn’t play a role. In the classroom, students can basically maintain the correct sitting posture due to the mutual supervision of teachers or classmates. , but when doing homework or reading at home, they tend to be slack. Therefore, a desk that can correct the sitting posture of students is needed. There are many studies in related aspects of the existing technology, but most of them are the adjustability of the desk and the use of alarms. Device alarm, invention patent 201410014242.6 discloses an anti-myopia instrument, but the structure is complex. In practical applications, students will inevitably lower their heads slightly when reading and writing, so that it is impossible to accurately judge whether the student’s sitting posture is correct. There are other invention patents that use airflow or alarm methods to remind users, but in the process of use, problems such as restrictions on alarm methods and reasonable use of light have not been reasonably resolved
