Problems solved by technology

In an ordinary space, the smoke released by the smoke alarm tester will slowly dissipate in the atmosphere. However, if this detection method is used in a clean room, the smoke will not be completely discharged when it diffuses in the clean room, and will affect its next detection, therefore, its structure needs to be further improved

Abstract

The invention discloses a smoke alarm tester. The smoke alarm tester includes a control center and a test chamber; the test chamber is arranged on an annular channel formed by a pipeline; the test chamber is provided with at least one test bogie; the annular channel is provided with a blower with a built-in aerosol generator, an optical probe pipeline with a built-in optical probe, a first pipeline valve, a second pipeline valve and an electric wing blade valve, wherein the electric swing blade valve is arranged between the first pipeline valve and the second pipeline valve; the control center is in control connection with the blower, the aerosol generator, the first pipeline valve, the second pipeline valve and the electric wing blade valve respectively; and the optical probe is connected with the control center through an optical signal processing apparatus. The smoke alarm tester of the invention has the advantages of simple structure, convenient operation, high detection efficiency and high accuracy.

Description

technical field [0001] The invention relates to the technical field of smoke alarm detection, in particular to a smoke alarm tester. Background technique [0002] Smoke alarm, as a kind of alarm, is widely used in daily life; smoke alarm realizes fire prevention by monitoring the concentration of smoke. [0003] Smoke alarms are not only subject to ex-factory inspection when the product leaves the factory, but also must be regularly inspected during use. In the long-term use of the smoke alarm, it needs to be tested regularly to ensure that the smoke alarm can operate effectively. The smoke alarm tester is an instrument that is often used to check the effectiveness of the smoke alarm. The existing smoke alarm tester detects the effectiveness and sensitivity of the smoke alarm by releasing smoke. In an ordinary space, the smoke released by the smoke alarm tester will slowly dissipate in the atmosphere. However, if this detection method is used in a clean room, the smoke wil...
