People to the impression of cigarette mainly from flue gas; fume indication is also the important indicator for evaluating cigarette harmfulness simultaneously; therefore; need to trap cigarette smoke; absorption bottle method of trapping is to one of important method of flue gas gas gas-phase objects trapping, but often can there is absorption liquid in this trapping process, is entered in smoking machine pipeline by suck-back, pollutes and corrosion smoking machine equipment; smoking machine equipment has been caused to great infringement, shortened its serviceable life.For overcoming above-mentioned technical matters, someone has increased non-return valve on absorption bottle, can prevent absorption liquid suck-back, but simultaneously non-return valve has also stoped the emptying of flue gas in collecting bag, cause in collecting bag flue gas overfill cannot get rid of and be back to indoor, thereby cause indoor fume indication still not reach standard level.
Summary of the invention
The problem existing for above-mentioned prior art, a kind of anti-absorption bottle absorption liquid suck-back device of the present invention, can effectively trap flue gas, prevent absorption liquid by suck-back, entered smoking machine in, do not affect the emptying of flue gas in collecting bag, avoid collecting bag to be back to indoor because of flue gas overfill.
For solving the problems of the technologies described above, a kind of anti-absorption bottle absorption liquid suck-back device of the utility model, comprises smoking machine, is located at the exhaust duct at smoking machine top, connecting pipe, collecting bag, pipe, absorption bottle, and smoke-intake pipe; Described smoke-intake pipe and pipe stretch in absorption bottle, and described smoking machine is connected with smoke-intake pipe entrance point by connecting pipe, and pipe endpiece is connected with collecting bag by connecting pipe, and collecting bag is connected with smoking machine by connecting pipe; Non-return valve one is installed between smoking machine and collecting bag, and smoke-intake pipe entrance point and pipe endpiece are separately installed with non-return valve two.
Preferably, the shell ovalize of non-return valve one and non-return valve two, inside is provided with the cone spool can move freely, and described cone spool side is provided with some grooves along bottom.
Further, the base diameter of cone spool is greater than the diameter of connecting pipe.
Preferably, cone spool is made by rubber.
Compared with prior art, the utility model arranges three non-return valve, be arranged on respectively smoke-intake pipe and pipe place, and between smoking machine and collecting bag, and be arranged on the non-return valve at smoke-intake pipe and pipe place and be arranged on smoking machine and collecting bag between non-return valve opposite direction, during cigarette smoking, the pipeline that connects absorption bottle limit is unimpeded, and another side is by non-return valve closing pipe line, when collecting bag is emptying, by non-return valve, seal the pipeline that connects absorption bottle limit, and another side pipeline is unimpeded, thereby trapping flue gas and do not affect collecting bag in flue gas emptying in, effectively prevented that smoking machine is in the exhaust process of having aspirated, absorption liquid suck-back in absorption bottle is entered in smoking machine pipeline, prevented that absorption liquid is to the corrosion of smoking machine and pollution, reduced because absorption liquid is by suck-back, and the workload of again aspirating.The utility model is simple in structure, is easy to manufacture, and has effectively improved work efficiency.

In figure: 1. smoking machine, 1-1. exhaust duct, 2. non-return valve one, 3. connecting pipe, 4. collecting bag, 5. non-return valve two, 6. pipe, 7. absorption bottle, 8. smoke-intake pipe, 9. cone spool, 9-1. groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of anti-absorption bottle absorption liquid suck-back device of the utility model, by smoking machine 1, is located at the exhaust duct 1-1 at smoking machine 1 top, connecting pipe 3, and collecting bag 4, pipe 6, absorption bottle 7, and smoke-intake pipe 8 forms; Described smoke-intake pipe 8 and pipe 6 stretch in absorption bottle 7, and described smoking machine 1 is connected with smoke-intake pipe 8 entrance points by connecting pipe 3, and pipe 6 endpiece are connected with collecting bag 4 by connecting pipe 3, and collecting bag 4 is connected with smoking machine 1 by connecting pipe 3; It is characterized in that, between smoking machine 1 and collecting bag 4, non-return valve 1 is installed, smoke-intake pipe 8 entrance points and pipe 6 endpiece are separately installed with non-return valve 25.
As preferred version of the present utility model, the shell ovalize of described non-return valve 1 and non-return valve 25, inside is provided with the cone spool 9 can move freely, and described cone spool 9 sides are provided with some groove 9-1 along bottom, be convenient to flue gas and flow away from groove 9-1.
As improvement of the present utility model, the base diameter of described cone spool 9 is greater than the diameter of connecting pipe 3, and in the time of smoke evacuation or smoking, cone spool 9 can be blocked connecting pipe 3 mouths of pipe effectively, to control the flow direction of flue gas.
As preferred version of the present utility model, described cone spool 9 is made by rubber, and rubber has certain elasticity, good seal performance, can block connecting pipe 3 mouths of pipe preferably, simultaneously the lighter weight of rubber, be easy to be promoted by flue gas, thereby reach the object of smoking or smoke evacuation.
