Problems solved by technology

Now the general household doors are made of solid wood or MDF, which do not have fireproof performance. When a fire breaks out, the general walls are made of bricks and cement, which is not easy to catch fire. The fire is most likely to be transmitted and spread from the door.

[0003] And the doors in the prior art do not have fireproof performance, let alone the specific fire extinguishing function

When a fire broke out, the door was burned to the point of deformation and could not be opened, which delayed the best escape time for the trapped people.
