in the figure: air brick seat 1, detection subassembly 2, air brick 3, intake pipe 4, test rod 21, alarm lamp 22, first electric wire 23, battery 24, battery fixing base 25, second electric wire 26.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1, in a preferred embodiment of the present invention, the air brick capable of displaying thickness variation in real time includes an air brick seat 1, a detection assembly 2, an air brick 3 and an air inlet pipe 4; the vertical setting of

air brick seat
