Suction resistance detection principle: the first constant air source generating device stabilizes the air source pressure detected by the suction resistance in the built-in volume module at 210kPa through the air pressure regulating valve, and sends air to the suction resistance and ventilation degree sensing device through air passage connection. After the cigarettes are transferred to the detection wheel from the turning wheel, the cigarettes in the cigarette groove of the detection wheel cling to the detection cap. When the detection wheel rotates, the cigarette is pressed to the detection cap to form air tightness. And a second pressure sensor 2400 in the air tightness and resistance suction sensing device receives the pressure of the gas and obtains the resistance suction of the cigarette according to the pressure.
The principle of ventilation degree detection: first invariable air supply generating device is through the air pressure regulating valve with the air supply pressure that the gas tightness detected in the built-in volume module at 1.7Kpa to on sending gas tightness and suction resistance sensing device through the gas circuit connection, after cigarette turned round on the cigarette machine is followed and is transmitted the detection wheel, the cigarette that is located detection wheel cigarette groove is hugging closely and is detecting the cap, when detecting the rotation of wheel, cigarette is pressed to the detection cap, forms gastightly. The first pressure sensor 2300 or the second pressure sensor 2400 in the airtightness and suction resistance sensing apparatus receives the pressure (inlet pressure) of the gas, and the pressure sensor in the ventilation degree sensing apparatus also receives the pressure (outlet pressure) of the gas at this time. The total draft can be calculated from the inlet pressure and the residual pressure as follows: draft = (inlet pressure-residual pressure)/inlet pressure.
The above-mentioned embodiments are only one of the preferred embodiments of the present invention, and the general changes and substitutions performed by those skilled in the art within the technical scope of the present invention should be included in the protection scope of the present invention.
