Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that when using the detection equipment to detect the outer window, a static pressure box is formed between the film, the door, window and the wall, and when the pressure supply system detects the air tightness of the door and window, the static pressure The air in the box may flow out or flow in through the gap between the door, window and the wall, which will affect the test results, and thus have the defect of inaccurate test results of the test equipment

Abstract

The invention relates to a building external window air tightness detection device which comprises a sealing assembly and a first pressure supply assembly, wherein the sealing assembly is arranged onthe peripheral side of an external window, a first air hood is fixedly arranged on the sealing assembly, a closed space is formed among the first air hood, the sealing assembly and the external window, and the first pressure supply assembly is communicated with the first air hood. By arranging the first pressure supply assembly, the sealing assembly and the first air hood, the influence of a gap between the outer window and the wall on the airtightness detection of the outer window is reduced, and the accuracy of the airtightness detection of the outer window is improved.

Description

technical field [0001] The present application relates to the technical field of airtightness of building exterior windows, in particular to a device for detecting airtightness of building exterior windows. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for the living environment are getting higher and higher. The actual energy-saving effect of doors and windows is evaluated through the comprehensive evaluation of thermal insulation and air tightness. The airtightness of building exterior windows is a very important factor affecting the energy consumption of building air conditioners. In order to save energy and improve the indoor thermal environment, it is necessary to test the airtightness of exterior windows. [0003] In related technologies, for example, the Chinese utility model patent with the notification number CN207610828U discloses a portable on-site detection device for door and window airtightness...
