Description
Technical field
The invention belongs to cigarette and burn and suck index detecting instrument field, be specifically related to a kind of controlled constant flow rate smoking machine of capacity that aspirates.
Background technology
In laboratory, carry out, in the detection of the indexs such as Chemical Components in Cigarette Smoke, temperature of combustion, generally using various smoking machines.For the detection data that make to obtain between each laboratory have comparability, GB/T 16450-1996 " smoking machine definition and standard conditions for conventional analysis " has stipulated that the standard aspiration mode is suction time 2s, suction interval 58s, every mouthful of suction capacity is 35ml, and mostly the smoking machines such as at present uses are around this standard design.
Burn and suck index especially during the research aspect cigarette burning temperature and smoke components formation mechanism carrying out cigarette, Smoking regime adjustable extent underaction due to current conventional smoking machine, relevant research work runs into more difficulty: when during to cigarette smoking, the inner Temperature Distribution of burning cone is detected, because can not make the cigarette of burning in the stable aspiration phases that continues, therefore can't determine that the difference of different cigarette burning Temperature Distribution has comparability; The cigarette such as burning can't wait the continuous sucking state in stable, thereby can not observe and detect impact and the influence degree of the inhibiting tape of kinds of cigarettes on Temperature Distribution; Due to the Burning velocity of kinds of cigarettes, there is some difference, may cause its puff number difference, may there be larger error in the single port growing amount of the main flume composition detected, and larger data error is brought and comparatively seriously waited impact the research of Chemical Components in Cigarette Smoke generting machanism.
Chinese patent (application number 201210267759.7, publication number CN102749229A) discloses the stable aspirator that continues of the controlled cigarette of a kind of flow.This device can provide stablizes lasting Smoking regime, can carry out adjusting in a big way to the flow aspirated according to the experimental study demand, has certain extensibility.This device can carry out cigarette continue suction Temperature Distribution and the detection of relevant granule phase substance.Although this device solves the problem of continuous sucking, this plant automation degree is not high; Exhaust gases passes can't clean in time, may cause the poor repeatability of experimental result; Still the side-stream smoke in the time of can not gathering cigarette burning; Burning situation is subject to surrounding environment influence.
Summary of the invention
Purpose of the present invention just is being based on the deficiencies in the prior art and a kind of smoking machine of constant flow rate is being provided.The smoking machine of this constant flow rate can be realized the flow control of smoking machine and constant, and cigarette is carried out to the constant flow rate suction, facilitates collection and the detection of main flow and side-stream smoke, and can be cleaned exhaust gases passes, reduces impact on burning and sucking process etc.
The objective of the invention is to be achieved through the following technical solutions: a kind of constant flow rate smoking machine, comprise the cigarette clamper be arranged on top panel, be connected to the TPM drip catcher on the main flume pipeline of cigarette clamper rear end in turn, reversal valve, the detection of gas flow rate control device, vacuum pump and main flume are collected a mouthful formation, on plate, be equipped with in the above for collecting the plexiglass tent of side-stream smoke, have side-stream smoke outlet being positioned on the top panel of cloche, this outlet is equipped with the side-stream smoke filter screen and collects mouth with side-stream smoke blower fan and side-stream smoke and is communicated with, the TPM drip catcher is arranged on top panel, and reversal valve, detection of gas flow rate control device, vacuum pump are arranged on the base plate that is positioned at the top panel below, and reversal valve is provided with the cleaning air-path interface.
See in the present invention, the side-stream smoke blower fan is provided with the wind speed adjusting knob, regulates the efflux velocity of side-stream smoke.
Be provided with Cambridge sheet in the TPM drip catcher; The TPM drip catcher is inlaid in the lower face position of top panel.
Base plate is provided with leg, is convenient to the stable of smoking machine and puts.
the course of work of the present invention is:
Aspiration procedure: cigarette is inserted to the cigarette clamper, connect instrument power source, start vacuum pump, solenoid directional control valve is adjusted to " suction " passage, the adjusting gas flow detection control apparatus is to setting flow, light cigarette, start the constant flow rate suction, main flume enters the TPM drip catcher, cambridge filter trapping granule phase substance wherein in drip catcher, the main flume that sees through cambridge filter enters the detection of gas flow rate control device through solenoid directional control valve, by after vacuum pump, by main flume, collecting a mouthful discharge.While needing to detect the smoke components of main flume, can collect on mouth and connect the main flume gathering-device at main flume, flue gas is collected, the standby survey keeps sample.
When cigarette is aspirated at constant flow rate, its side-stream smoke by the side-stream smoke filter screen, is discharged smoking machine via blower fan in plexiglass tent, and efflux velocity is regulated by the wind speed adjusting knob, and the side-stream smoke of discharge can collect by the gas collection bag, and standby the survey keeps sample.
Cleaning process: after sample detection is carried out repeatedly in the suction experiment (being less than 30 times), to be cleaned the main flume passage, solenoid directional control valve is switched to " cleaning " passage, purge gas (being generally inert gas) on the cleaning gas crossing connects, start vacuum pump, the adjusting gas flow detection control apparatus is to maximal value, start suction, now purge gas enters solenoid directional control valve and cleaning gas crossing connecting tube by the cleaning gas crossing, pass through solenoid directional control valve, enter the detection of gas flow rate control device via connecting tube, via connecting tube, enter vacuum pump, collect a mouthful discharge smoking machine by pipeline by main flume again.
Compared with prior art, the present invention has the following advantages: can stablize the cigarette suction flow, realize setting and the control of constant flow rate; Can clean in time exhaust gases passes, greatly reduce the impact that experimental result is caused; Can expand main flume and side-stream smoke while gathering cigarette burning, realize main flume and side-stream smoke composition are carried out to analyzing and testing; The cigarette combustion process is not subject to surrounding environment influence; The automation equipment degree is higher, easy and simple to handle, reproducible.
