Embodiment 1

[0038] Example 1: A smoke concentration detection test device, such as figure 1 , Including the cabinet 1, the smoke generator 2 and the test component 3 (such as figure 2 ), the box 1 is set in a ring shape, and the smoke generator 2 is connected to the box 1 and communicates with the inside of the box 1. When the smoke generator 2 is working, smoke can be blown into the box 1, thereby making the box 1 is filled with smoke to be tested.

[0039] Such as figure 2 The box body 1 is provided with three pairs of oppositely arranged first connection ports 11 and second connection ports 12, and each pair of the first connection port 11 and the second connection port 12 is provided with a set of test components 3. The test assembly 3 includes a light source 31, a first light source receiving end 32, and a second light source receiving end 33. The first light source receiving end 32 and the second light source receiving end 33 are both set as photocells, so that light intensity can be ...

Embodiment 2

[0047] Embodiment 2: A method for testing smoke concentration, including embodiment 1. The operator emits a test light through the luminous source 31 to test the smoke, and the test component 3 in embodiment 1 obtains that the test light passes through the smoke to be tested After the final light intensity d2 and the initial light intensity d1 of the test light before passing through the smoke to be tested, the difference △d between the initial light intensity d1 and the final light intensity d2 is calculated, and △d can intuitively reflect the tested smoke concentration.

Abstract

The invention discloses a smoke concentration detection test device and a testing method thereof, belongs to the field of smoke concentration testing, and aims to provide the smoke concentration detection test device and the testing method thereof. The technical scheme has the key points as follows: the smoke concentration detection test device comprises a box, a smoke generator and a testing assembly, wherein the smoke generator is communicated with the interior of the box; a first connecting port and a second connecting port are oppositely formed in the box; the testing assembly comprises alight-emitting source, a first light source receiving end and a second light source receiving end; the light-emitting source and the first light source receiving end are positioned on one side, away from the second connecting port, of the first connecting port; the second light source receiving end is positioned on one side, away from the first connecting port, of the second connecting port; a semi-transmitting and semi-reflecting mirror for refracting a part of a light source into the first light source receiving end and transmitting a part of the light source into the first connecting port is arranged between the light-emitting source and the first light source receiving end. The smoke concentration detection test device has the advantages as follows: influences of voltage fluctuation ofthe light-emitting source on a testing result can be reduced, and the testing accuracy can be improved.

Description

Technical field [0001] The invention relates to the field of smoke concentration detection, in particular to a smoke concentration detection test device and a test method thereof. Background technique [0002] The Chinese patent publication number CN107300541A discloses a method for quantitatively characterizing the mass concentration of e-cigarette smoke. Use the analog suction device to trigger the e-cigarette to generate smoke, and use a transparent container as a smoke measurement chamber to collect the generated e-cigarette smoke in real time. Use the laser beam to irradiate the transparent smoke measurement chamber to measure the incident light intensity I and the transmitted light intensity I0 of the laser beam, Calculate the light transmittance T; then use the relational expression to perform real-time quantitative characterization of the mass concentration of e-cigarette smoke. [0003] However, during the test process of this test method, since the voltage of daily elect...
