Embodiment Construction

[0022] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown in the device for measuring the harmfulness of passive smoking, cigarette smoke inlet 6, air inlet 12, air intake peristaltic pump 2, air outlet 7 of the exposure hood are connected with the exposure hood 1 through a rubber conduit; The animal 4 is placed together with the breeding cage 5 in the exposure cover 1; the exposure cover 1, the exhaust hole 8 of the exposure cover, the exhaust peristaltic pump 3, and the pollution gas exhaust hole 9 are connected through rubber conduits; the exposure cover The fan 11 in 1 can quickly mix the gas in the poison exposure hood 1; the multi-gas detector 10 in the poison exposure hood 1 monitors the oxygen concentration, carbon monoxide concentration and smoke particle concentration in real time, and controls the intake peristaltic pump 2 , Exhaust peristaltic pump 3 so as to realize sufficient o...

Abstract

The invention discloses a method and a device for measuring the harmfulness of passive smoking. A test animal and a rearing cage are arranged in a hermetic contamination cover; a cigarette is ignited, and the mixing gas of the air and the smoke is continuously fed through a gas inlet circuit; the concentration of oxygen, the concentration of carbon monoxide and the concentration of smoke grain phase matters in the contamination cover are maintained relatively constant; and the test animal lives in the contamination cover, the reaction of the test animal is observed, and the quantity of the cigarette smoke grain phase matters sucked by the test animal is calculated to obtain the harmfulness of the smoke passively sucked by the test animal. The invention overcomes the defects that the concentration of the cigarette smoke grain phase matters can not be accurately controlled and measured, and the structure is quite complicated in the prior art, can accurately measure and control the concentration of the cigarette smoke grain phase matters in the cover, and measures the harmfulness of the passive smoking more accurately. Meanwhile, the device is simpler and can be widely applied to the cigarette field.

Description

technical field [0001] The invention relates to a measuring method and device, in particular to a method and device for measuring the harmfulness of passive smoking. Background technique [0002] Smoking, as a living habit with a long history, is an important part of modern people's life. But smoking is harmful to the body is also the formula of the industry. With the improvement of people's living standards, the impact of smoking on people's health has attracted more and more attention. Especially passive smoking, that is, the harm caused by second-hand smoke to the human body cannot be ignored. There are many testing methods for the harmfulness of active smoking, mainly by measuring the relationship between the harmful substances in cigarettes and the state of the smoker, but it is more difficult to measure the harmfulness of passive smoking. This is because cigarette smoke is a complex component, and the harmfulness of various harmful components is unknown; and the tox...
