[0002] A fire extinguisher, also known as a fire extinguisher, is a portable fire-fighting tool. It contains chemicals to put out fires. It is one of the common fire prevention facilities. The equipment used to store fire-extinguishing fluids is usually steel cylinders, which are steel cylinders for storing high-pressure oxygen, coal gas, liquefied petroleum gas, etc. Therefore, pressure testing of steel cylinders becomes an indispensable link.

[0003] There are many devices for detecting the pressure inside the fire extinguisher cylinder in the prior art. However, when the detection device for detecting the pressure inside the fire extinguisher cylinder in the prior art is used, although the pressure inside the cylinder can be detected, during the detection process, the detection personnel cannot intuitively determine whether the cylinder is ruptured or leaking. If the rupture of the cylinder is small, it is difficult to be discovered by observing the pressure gauge for a while, which makes it easy to be ignored, so that the damaged cylinder has a greater safety hazard in subsequent use.

[0004] Therefore, we provide a device for intelligently detecting the pressure inside a fire extinguisher cylinder to solve the defects in the prior art. Utility Model Content
