Embodiment 1

[0016] Embodiment 1: as Figure 1-2 As shown, a smoke amount measuring device includes a control assembly, a suction assembly, a smoke collection assembly, a smoke pipeline 7, a clamp assembly, a heating assembly 10 and a measurement assembly, and the control assembly includes a PC 1 and a programmable control device 2, the suction assembly includes a suction pump 3, a metering flowmeter 4 and a suction pipeline 5, and the smoke collection assembly includes a trap 6 and a Cambridge filter placed inside the trap 6, the The clamping assembly includes a soft rubber joint 8 and a bracket 9, and the measuring assembly is a thermal resistance temperature sensor 11, a voltmeter 12 and an ammeter 13;

[0017] Described PC machine 1 is connected with programmable controller 2, and heating assembly 10 is connected with voltmeter 12, ammeter 13, programmable controller 2 successively, and programmable controller 2 is connected with suction pump 3, thermal resistance temperature sensor 11...

Embodiment 2

[0023] Example 2: Measurement of smoke volume of traditional cigarette Hongtashan:

[0024] Set the suction conditions: the suction time is 2.7s, the suction interval is 30s, the number of suction ports is 15, and the suction volume is 35ml. KC = 0.3023J / (mg*°C).

[0025] If the tobacco product is a cigarette, insert the tobacco product above the clamping assembly for suction. After the temperature difference is stable, light the tobacco product and start smoking. The programmable controller collects and transmits the data of the voltmeter and ammeter to the PC. After PC calculation, the following data are obtained:

Embodiment 3

[0028] Example 3: Measurement of smoke volume of electronic cigarette Colorful Rhyme (cured tobacco type 5mg):

[0029] Set the suction conditions: the suction time is 2.7s, the suction interval is 30s, the number of suction ports is 20, and the suction volume is 35ml. KC=0.1808J / (mg*°C).

[0030] If the tobacco product is an electronic cigarette, connect it to the power supply first, insert the tobacco product into the air above the clamping assembly to smoke, wait for the temperature difference to stabilize, heat the tobacco product to start smoking, and the programmable controller will collect the data from the voltmeter and ammeter And send it to the PC, and get the following data after calculation by the PC:

Abstract

The invention relates to a smoke amount measuring device and a smoke amount measuring method, and belongs to the field of tobacco product detection. The smoke amount measuring device comprises a control component, a sucking component, a smoke collection component, a smoke pipeline, a clamping component, a heating component and a measuring component, wherein the control component comprises a PC (Personal Computer) and a programmable controller; the sucking component comprises a sucking pump, a flowmeter and a sucking pipeline; the smoke collection component comprises a capturer and a cambridge filter arranged inside the capturer; the clamping component comprises a soft rubber connector and a bracket; and the measuring component consists of a thermal resistance temperature sensor, a voltmeter and an ammeter. By adopting the smoke amount measuring device, the smoke amount is calculated according to a heat exchange relationship between smoke and heating elements inside the smoke pipeline, parameters are modified through an electronic scale, and an actual smoke amount of a tobacco product is measured.

Description

technical field [0001] The invention relates to a device and method for measuring smoke volume, belonging to the field of tobacco product detection. Background technique [0002] Tobacco products are the most regulated commodities in the world. Canada Tobacco Notification stipulates that testing and measuring the components and emissions of tobacco products are required; manufacturers and importers are required to report to the Ministry of Health in detail the composition and emissions of their tobacco products, including notification products; manufacturers and importers are required to Disclose information on the brands and types of each tobacco product. The regulation of tobacco products puts higher demands on the R&D, production and testing of tobacco products. The evaluation and analysis of tobacco products are mainly realized by analyzing the smoke produced after lighting tobacco products. Smoke yield refers to the mass of smoke particles in the volume produced by a...
