Description

Flexible expansion linear type smoking machine device and method for mounting trap
Technical Field
The invention relates to a smoking machine device, in particular to a flexible expansion linear smoking machine device for smoking detection of electronic cigarette products and a method for quickly installing a trap.
Background
The electronic cigarette is a novel tobacco product which is developed most rapidly in recent years, tobacco tar made of propylene glycol, glycerol and a certain content of nicotine is adopted, an electric heating atomizer is infiltrated to achieve atomization, the electronic cigarette product is considered to be a substitute of a traditional cigarette with low harm, and harmful substances generated in the combustion process of the cigarette product are effectively reduced by the heating atomization mode of the electronic cigarette. With the rapid development of the electronic cigarette market in recent years, the safety problem of electronic smoke has attracted attention of various experts and scholars, and the quality safety of electronic cigarette products sold in the market at present has attracted more and more controversy. Aiming at the research of the aspects of determining harmful components in the tobacco juice and aerosol of the electronic cigarette and the like, the precondition is that the smoke components are captured by truly simulating the smoking behavior so as to determine the components of the electronic cigarette product, evaluate the safety and guarantee the safety of consumers.
The atomizing agent of electron cigarette product is liquid tobacco tar, and the electron cigarette user can habitually downward sloping every single move electron cigarette when inhaling the electron cigarette, makes the tobacco tar be in the bottom of atomizer, avoids the tobacco tar to inhale into the portion and shines into inappropriately. In order to avoid peculiar smell generated by oil shortage and dry burning, the electronic cigarette is intentionally pitching in the process of smoking the electronic cigarette so that the tobacco tar flows to continuously infiltrate the glass fiber oil guiding rope and the atomizer, and the oil guiding effect and the atomization amount are stable.
The prior art smoking device has several technical problems:
1. the capacity (number of channels) of the smoking device is fixed:
fig. 1 is a schematic structural view of a prior art linear type smoking machine in which a fixed number of suction openings 100 are arranged in a straight line, and each suction opening 100 corresponds to an independent suction unit, so that it has samples of the same number as the suction openings to be tested at the same time. The linear type large-capacity synchronous suction has the advantages that a plurality of groups of samples can be synchronously sucked at large capacity, and the working efficiency is higher. In patent document CN 103674761A entitled "automatic cigarette smoke analyzer", a plurality of linearly arranged smoking holes 2 are fixed in capacity (number of holes) during design and construction of the apparatus, and are difficult to expand, and when a large-capacity smoking machine is required for detection, only the large-capacity smoking machine can be replaced. In the face of the rapid development of the electronic cigarette technology, the capacity of the existing equipment is insufficient through detection work, future application requirements are often considered when a user unit purchases equipment, the capacity of the equipment for selection is expanded, the capacity is excessive, and the problem that the flexible capacity expansion cannot be performed on a smoking machine in the prior art is solved. The laboratory with a plurality of devices can not utilize the existing resources to realize flexible splicing and solve the problem of capacity expansion, so as to smoothly complete the test or detection task with complex and variable requirements.
2. The structure of the smoking machine is not adjustable:
most of the conventional linear smoking machines are designed and manufactured according to the technical specification of smoking machine definition and standard conditions for GB/T16450 conventional analysis. In the process of testing the electronic cigarette product, an oil cavity of the electronic cigarette is in a horizontal static state, tobacco tar is always deposited below the liquid storage cavity under the action of gravity, and the tobacco tar is consumed along with the continuous testing process. When the residual amount of the tobacco tar is reduced to the extent that the upper glass fiber oil guide rope can not be ensured to be soaked and supplemented with the tobacco tar all the time, the atomized amount can be greatly changed due to insufficient supplement amount of the tobacco tar, and the smoke amount is reduced. Multiple e-cigarette samples or individuals with the same design may produce different aerosol results during the actual testing process. Compared with other electronic cigarette oil storage cavities with different designs, such as an electronic cigarette with oil guide cotton wrapped in oil storage cotton, the tobacco tar supplement amount and the supplement timeliness can be different due to different detection equipment or detection methods, and finally the detection result can deviate and the error can be increased.
As shown in fig. 2, in the carousel-type electronic cigarette disclosed in patent document with publication number CN 106932296A and name "electronic cigarette smoking machine", the central axis of the carousel (200) is parallel to the horizontal plane, the electronic cigarette rotates along with the carousel (200) during smoking, but the electronic cigarette always keeps horizontal rotation, and the tobacco tar rolls along the inside of the electronic cigarette tar cavity and lacks pitching motion, so the effect of the tobacco tar infiltrating the atomizer is not ideal.
3. The problem of inaccurate detection result:
compared with appendix F in national standard GB41700-2022 electronic cigarette, the detection process in the detection standard of the determination of the release amount of formaldehyde, acetaldehyde and acrolein in the electronic cigarette release 2, 3-butanedione is shown in figure 3, and the smoke of the electronic cigarette 1 passes through the electronic cigarette holder 2, the connecting pipeline 3, the solution trap 4, the trap 5 and the suction unit 6. In operation, the smoke of the electronic cigarette is generated by heating the atomizer, and due to the temperature reduction in the transmission process, a large amount of condensation can occur on the inner wall of the connecting pipeline 3, so that part of the released substances cannot reach the solution trap 4 in time, and the problem can cause the release amount of harmful components to be less than the actual release amount.
Fig. 4 is a schematic diagram of a trap connection structure of a linear smoking machine in the prior art, and the trap connection mode is shown in fig. 4 when detection is performed according to detection specifications. The electronic cigarette 1 is inserted into the electronic cigarette holder 2 for smoking, the cigarette holders of the electronic cigarettes are different in size and shape, most of the cigarette holders of the electronic cigarettes are not circular, and the electronic cigarettes cannot be directly inserted into the standard holder 2 in GB/T-16450 for smoking. In the process, an operator usually adopts a silicone tube with the diameter matched with the trap and a thick silicone tube with the diameter suitable for the electronic cigarette holder to connect the tubes, and the silicone tube is sleeved on the electronic cigarette holder and then sealed by a tetrafluoro sealing film. The silicone tube is inserted on the electronic cigarette holder 2, and a large amount of tobacco tar can be condensed in the cavity during smoking. The inlets of the clamp 2 and the trap 4 are connected through a hose 3, the two traps are butted through a hose 8, the trap 4 and the trap 5 are connected through a hose 7, and the trap 5 is connected to a suction unit 6 positioned in a cabinet 10 through a hose 9. The whole flue gas transmission path needs to be switched by 5 hoses, and the condensate of the pipeline is evaluated by measuring the weight difference of the pipeline before and after the test, and the results are shown in the following table 1:
Figure BDA0003796710750000031
TABLE 1
In the prior art, the pipeline connection is large in dead volume, the transmission path is long, the condensation phenomenon is serious, the smoking result cannot have large error and high fluctuation, and the release amount of harmful substances cannot be truly reflected. In addition, the condensation of the pipeline causes cross contamination among samples, and greater uncertainty is brought about. The pipeline condensation causes potential equipment safety hazards and equipment maintenance working strength, and if the pipeline condensation is not cleared in time, the pipeline condensation can be sucked into a smoking machine suction unit to cause damage to instrument equipment.
Table 2 shows the implementation effect of the technical solution of the present invention, and the data thereof are shown in the following table:
Figure BDA0003796710750000032
TABLE 2
Compared with the prior art, the condensate of the aerosol pipeline is reduced from 5482mg to 139mg in the implementation process of the technical scheme of the invention, the condensation loss of the pipeline is reduced by 97.5%, the installation and leakage detection time of the 10-channel trap is reduced from 47.5 minutes of the original hose connection to 5.2 minutes, the time of 42 minutes is saved, and meanwhile, the solvent suck-back accident caused by reverse connection of the pipeline can be avoided.
4. The smoking machine pipeline connection is inefficient, reveals easily, examines the difficult problem of leaking stoppage:
the safety, the correctness and the sealing performance of trap connection are prerequisites for ensuring the smooth running of the test, and each test is time-consuming work of connecting and building the trap by an operator. Taking a 20-channel test as an example, each channel is connected with 2 trapping traps, 1 gripper and 1 trap in series, the total number of the trapping traps, 20 grippers and 20 traps is 40, 80 hoses need to be connected, the total number of the hoses needs to be connected with 220 joints, and the average time is 60-90 minutes.
The operator needs to perform capacity check and leakage check on each connected suction duct, and if air leakage is found, the operator needs to check the pipe connection of the duct one by one, and the total number of 220 sealing points with possible air leakage is calculated. In actual work, operators usually wind all the joints with the tetrafluoro sealing film, so that air leakage is avoided, and labor intensity is greatly increased. In addition, an operator is connected with a glass interface of the solution trap through a pipeline, the glass can easily cut gloves and hurt fingers, and solvent overturn accidents often happen to intensive pipeline connection. Meanwhile, the connection of the trap in the prior art is a heavy and repeated work of an operator, which seriously affects the work efficiency and is a problem expected to be solved by the operator for a long time.
5. The wrong connection of the trap can cause problems:
as shown in fig. 5, the trap of the prior art is fired from quartz glass, and the outlet 5 and inlet 6 of the trap 4 are glass tubes of the same outside diameter. When a 20-pore experiment is adopted, 80 intensive trapping traps are densely distributed in pipelines and are narrow in space, an operator is easy to have the error of reversely connecting the inlets and the outlets of the supplementary trapping traps, if the error is not found before pumping is started, reverse suction accidents can occur, corrosive solution is sucked into a smoking machine suction unit, the smoking machine is polluted and corroded, and the suction unit is damaged, so that the experiment is interrupted. Trap connection is a place where an operator is very prone to errors or mistakes during operation.
In summary of various problems of the smoking machine in the prior art, the invention provides an innovative flexible expansion linear smoking machine device and an implementation method thereof, which can realize flexible expansion of the linear smoking machine device and improve accuracy and efficiency of a smoking machine detection result through novel structural connection and structural arrangement.
