[0002] Buildings refer to man-made assets, which fall into the category of fixed assets and include two categories: houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store goods, and conduct other social activities. What is different from buildings is structures, which refer to engineering buildings other than houses.

[0003] During the long-term use of the wall of a house, the wall interlayer will be eroded by water vapor, resulting in water accumulation inside the interlayer. If the accumulated water cannot be discharged for a long time, the wall will be damaged from the inside out, posing certain safety hazards. Therefore, it is urgent to propose a negative pressure device for draining water from the roof interlayer. Utility Model Content
