Description

Technical Field

[0001] The utility model relates to the technical field of air supply equipment, in particular to an air supply equipment for air tightness detection. Background Art

[0002] Doors and windows are important components of buildings. They not only provide lighting and ventilation for the house, but also play an important role in isolation. The air tightness of doors and windows cannot be ignored for the indoor environment. If the doors and windows are not tested for air tightness during construction, the air tightness will be poor, which will greatly affect the circulation and quality of indoor air.

[0003] At present, air supply equipment is needed during the air tightness test of doors and windows.

[0004] The existing air supply equipment for air tightness detection is composed of two hoses, a detection tube, a main unit and a fan. When in use, the main unit is connected to the fan through a hose, and the main unit is connected to the detection location through another hose. Then the fan delivers air to the detection location through the hose and the main unit, and then the air tightness is determined by the detection pressure value. However, in actual operation, since the air supply equipment itself does not have a self-test function, it is difficult to determine whether the air tightness of the door and window is unqualified or the air supply equipment itself has an air tightness problem when testing doors and windows, which reduces the accuracy of the test results. Therefore, an air supply equipment for air tightness detection is proposed. Utility Model Content
