| description | The invention discloses a airtightness detection device, and aims at detecting the airtightness of the airtight cavities. The device comprises a shell, a driving mechanism and a pressure detection device, wherein the shell is provided with an inner cavity for communicating an airtight cavity; the inner cavity is provided with a connection pipe for forming communication with the airtight cavity; afluid is stored in the inner cavity of the shell; the driving mechanism is arranged on the shell and is used for driving the fluid to continuously flow between the inner cavity and the airtight cavity; the pressure detection device is arranged on the connection pipe and is used for detecting the pressure parameter of the fluid flowing through the connection pipe; the pressure detection device is capable of rapidly and accurately judging whether the airtightness of the airtight cavity satisfies the requirements or not; and when the fluid is driven to flow to the inner cavity from the airtight cavity, the fluid for dete |
