Description

Technical Field

[0001] This utility model relates to the field of construction protection technology, specifically to a construction protective device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called the "construction site" or "construction site".

[0003] During construction, it is necessary to demolish and groove some walls and piles. A lot of dust is generated during demolition. Workers need to wear masks to cover their mouths and noses to prevent dust from entering. However, the existing masks do not fit the face well, and some dust still enters the mouth and nose. In addition, workers need more oxygen when working, and the existing masks make workers feel stuffy, which affects their work. Improvements are needed. Utility Model Content
