Embodiment 1

[0035] Specific embodiment 1 of the smoke exposure device of the present invention: as figure 2 As shown, it includes a smoking machine 1 , a smoke delivery system 5 and an exposure chamber 4 .

[0036] The smoking machine 1 is used for simulating human smoking to produce smoke. Specifically, the smoking machine 1 has an air extraction device 6 , and the air extraction device 6 sucks cigarettes to generate smoke through the reciprocating movement of its piston and pumps the smoke to the smoke delivery system 5 . Specifically, the smoking machine 1 can be one of a rotary table type, a single channel type, and a linear type of smoking machine. The specific structure and working principle of the smoking machine belong to the prior art and will not be repeated here.

[0037]The flue gas conveying system 5 includes an air intake pipeline 7 , a splitter device 8 and an air outlet pipeline 9 . Wherein, the distribution device 8 comprises a closed housing. In this embodiment, the...

Abstract

The invention relates to a smoke exposure device, which comprises a smoking machine for simulating a person to smoke a cigarette to generate smoke; the smoke conveying system is connected with the smoking machine; the number of the exposure bins is at least two, and smoke generated by the smoking machine is divided into the exposure bins through the smoke conveying system to contaminate cells. Thesmoke conveying system comprises a flow dividing device; the flow dividing device comprises a closed shell provided with an air inlet and at least two air outlets. The air inlet is directly or indirectly connected with the smoking machine; the air outlets are connected with the exposure bins, the air inlet and the inner wall face of the closed shell are oppositely arranged, smoke enters the innercavity of the closed shell through the air inlet, impacts the inner wall face of the closed shell to be evenly dispersed in the closed shell and evenly flows out of the air outlets, it is guaranteedthat the amount of the smoke entering the exposure bins is even, and then the accuracy of test results is guaranteed.

Description

technical field [0001] The invention relates to a smoke exposure device. Background technique [0002] The whole smoke exposure method has become an important exposure method for assessing smoke toxicity or biological effects in vitro. The exposure device based on this exposure method consists of a smoking machine, a smoke delivery system and an exposure chamber capable of gas-liquid interface exposure. The smoke generated by the smoking machine enters the exposure chamber through the smoke delivery system, and the cells in the exposure chamber are poisoned, and the toxicity or biological effects of the smoke are evaluated according to the results of the cell exposure. [0003] At present, commercially used smoke exposure devices such as Vitrocell and Cultex mainly realize smoke exposure by diluting smoke with air gradient. For its structure, take Vitrocell as an example, such as figure 1 As shown, the exposure device includes a smoking machine 1, a smoke delivery system ...
