[0001] The present invention relates to the technical field of teaching and lunch break desks and chairs, and specifically to a folding teaching and lunch break dual-purpose desk and chair. Background Art

[0002] For primary and middle school students, taking a lunch break can not only bring relaxation both physically and mentally, but also significantly improve the learning efficiency in the afternoon. However, schools generally do not provide lunch break beds for students to rest during the break, resulting in a large number of students lying on their desks to sleep, which affects the physical health of students. For example, nerves in multiple parts such as the eyes, arms, and face are compressed, causing nerve paralysis, or glaucoma, etc.

[0003] Existing folding lunch break desks and chairs can achieve the function of lying down to sleep by setting a foldable board under the desk and cooperating with the chair after pulling out the folding board. However, when taking a lunch break, the sunlight may be too strong and the brightness may be too high, which may cause some students to have difficulty falling asleep. They need to sleep by covering their eyes, such as wearing an eye mask. And some students are not used to the sleep method of wearing an eye mask, which may make it more difficult for some students to fall asleep. Summary of the Invention
