Regulating type dust collection device for classroom

Abstract

The invention discloses a regulating type dust collection device for a classroom. The regulating type dust collection device for the classroom comprises a first damping spring, a second damping spring, a collection groove, a lighting lamp, a collection tank and an exhaust fan. Through the arrangement of the first damping spring and the second damping spring which are used for collecting vibrationgenerated during working of a motor, the damping performance of equipment is improved. When dust in the classroom needs to be collected, firstly a mounting plate is fixedly installed directly above ablackboard through bolts and a regulating rod body extends and retracts in a barrel body, and thus the collection groove is directly below the blackboard. Through the arrangement of the lighting lampwhich is used for providing lighting for the blackboard, the practicability of the equipment is improved; the exhaust fan enables the dust in the classroom to further get through a wind guide pipe after getting through a dust collection cover and enter the collection tank, and thus collection of the dust in the classroom is realized, environment pollution caused by dust drifting is avoided, healthof students and teachers is guaranteed, and the environmental protection property of the equipment is improved.

Description

technical field [0001] The invention relates to a dust collection device, in particular to an adjustable dust collection device for classrooms. Background technique [0002] During the teaching process, after the dust is inhaled into the lungs, most of them are blocked in the alveoli. After a series of stimulation, chemical and immune effects, it can cause lung damage, including respiratory system inflammation and decreased pulmonary ventilation function. Common pulmonary Internal diseases include: chronic, acute pneumonia, lung cancer, pneumoconiosis, etc. , so that alveolar fibrosis, leading to decreased lung respiratory function).

AI Technical Summary

Problems solved by technology

Harm to the skin: during the teaching process of the teacher, the chalk dust will inevitably stick to the hands, and the particle dust floating in the air will also fall on the teacher's hair, face and neck, which will irritate the skin. If When sweat is hydrolyzed in hot weather, alkaline substances are produced, which is even more irritating to the skin and mucous membranes, because the living environment of human skin is a weakly acidic environment, which destroys the basic living environment of the skin under the action of dust alkalinity, and chalk dust makes the skin change. It is dry, rough, accompanied by itching, which makes the human body uncomfortable. In severe cases, it can cause acne, folliculitis, pyoderma, chapped skin and a large amount of hair loss, which affects and interferes with the normal work and life of teachers;

[0003] The noise generated by the existing dust collection device for classrooms during work is too easy to cause pollution to the classroom environment. At the same time, the shock absorption performance of the existing dust collection device for classrooms is poor. At the same time, the position of the existing dust collection device for classrooms is fixed. The dust collection range is small and the practicability is not strong
