Description
Technical field
The invention belongs to cigarette and burn and suck Indexs measure instrument field, be specifically related to the constant flow rate smoking machine that a kind of pumping volume is controlled.
Background technology
Carry out in the detection of the index such as Chemical Components in Cigarette Smoke, temperature of combustion in laboratory, the various smoking machine of general use.In order to make the detection data obtained between each laboratory, there is comparability, it is suction time 2s that GB/T16450-1996 " definition of conventional analysis smoking machine and standard conditions " define standard aspiration mode, puff interval 58s, mostly every mouthful of pumping volume is 35ml, at present uses grade smoking machine is around this standard design.
When carrying out cigarette and burning and sucking the research of index especially in cigarette burning temperature and smoke components formation mechanism, due to the Smoking regime adjustable extent underaction of current conventional smoking machine, relevant research work runs into more difficulty: to when during cigarette smoking, the Temperature Distribution of combustion cone inside detects, because the cigarette of burning can not be made to be in stable lasting aspiration phases, therefore cannot determine that the difference of different cigarette burning Temperature Distribution has comparability; The cigarette such as burning cannot be in stablize and wait continuous sucking state, thus can not observe and detect the inhibiting tape of kinds of cigarettes to the impact of Temperature Distribution and influence degree; Due to the Burning velocity of kinds of cigarettes, there is some difference, its puff number may be caused different, may be there is comparatively big error in the single port growing amount of the mainstream smoke constituents detected, the research of larger data error on Chemical Components in Cigarette Smoke generting machanism brings and comparatively seriously waits impact.
The cigarette stable that Chinese patent (application number 201210267759.7, publication number CN102749229A) discloses a kind of flow controlled continues aspirator.This device can provide the stable Smoking regime continued, and experimentally can carry out adjustment in a big way by the flow of Research Requirements to suction, have certain extensibility.This device can carry out that cigarette continues to aspirate Temperature Distribution and the detection of relevant granule phase substance.Although which solves the problem of continuous sucking, this plant automation degree is not high; Exhaust gases passes cannot clean in time, may cause the poor repeatability of experimental result; Still can not gather side-stream smoke during cigarette burning; Burning situation is subject to surrounding environment influence.
Summary of the invention
Object of the present invention provides a kind of smoking machine of constant flow rate just based on the deficiencies in the prior art.The smoking machine of this constant flow rate can realize the flow control of smoking machine and constant, carries out constant flow rate suction, facilitating collection and the detection of main flow and side-stream smoke, and can clean exhaust gases passes, reducing the impact etc. on burning and sucking process cigarette.
The object 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, detection of gas flow rate control device, vacuum pump and main flume are collected mouth and are formed, top panel is provided with the plexiglass tent for collecting side-stream smoke, the top panel being positioned at cloche has side-stream smoke outlet, this outlet is equipped with side-stream smoke filter screen and collects mouth with side-stream smoke blower fan and side-stream smoke and is communicated with, 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 below top panel, and reversal valve is provided with cleaning air-path interface.
See in the present invention, side-stream smoke blower fan is provided with wind speed adjusting knob, regulates the efflux velocity of side-stream smoke.
Cambridge sheet is provided with in TPM drip catcher; 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 cigarette clamper, connect instrument power source, start vacuum pump, solenoid directional control valve is adjusted to " suction " passage, adjusting gas flow detection control apparatus is to setting flow, light cigarette, start constant flow rate suction, main flume enters TPM drip catcher, cambridge filter trapping granule phase substance wherein in drip catcher, main flume through cambridge filter enters detection of gas flow rate control device through solenoid directional control valve, discharges by collecting mouth by main flume after vacuum pump.When needing the smoke components detecting main flume, can collect on mouth and connect main flume gathering-device, got up by fume collection at main flume, keep sample standby survey.
Cigarette is when constant flow rate aspirates, and its side-stream smoke is by side-stream smoke filter screen in plexiglass tent, and discharge smoking machine via blower fan, efflux velocity is regulated by wind speed adjusting knob, and the side-stream smoke of discharge collects by gas collection bag, and keep sample standby survey.
Cleaning process: after sample detection is carried out repeatedly in suction experiment (being less than 30 times), to clean main flume passage, solenoid directional control valve is switched to " cleaning " passage, purge gas (being generally inert gas) on cleaning gas crossing connects, start vacuum pump, 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 cleaning gas crossing, pass through solenoid directional control valve, detection of gas flow rate control device is entered via connecting tube, via connecting tube, enter vacuum pump, collect mouth by pipeline by main flume again and discharge smoking machine.
Compared with prior art, the present invention has the following advantages: Absorbable organic halogens cigarette suction flow, realizes setting and the control of constant flow rate; Exhaust gases passes can be cleaned in time, greatly reduce the impact that experimental result is caused; Main flume when gathering cigarette burning and side-stream smoke can be expanded, realize that analysis is carried out to main flume and side-stream smoke composition and detect; Cigarette combustion process is not by surrounding environment influence; Automation equipment degree is higher, easy and simple to handle, reproducible.
