Abstract
The utility model discloses a kind of scavenging conduits for the detection of cigarette purge and trap, its main body is a " u "-shaped pipe structure, it is characterized in that the bore of " u "-shaped pipe side tube body is greater than the bore of other side tube body, it is connected between the tube body of two sides by a truncated cone-shaped tube body, the round type tube body taper is 0.06~0.15.The U-tube air intake structure of the internal diameter variable diameter of the utility model inlet end from thick to thin, in the detection of cigarette purge and trap, cigarette filter stick may be stuck at the truncated cone-shaped tube body of variable diameter, on the one hand play the role of fixed cigarette, another aspect purge gass generate downward active force to cigarette, make to contact between cigarette and reducer pipe closer, purge gass can be prevented short-circuit, purge gass can be made all to pass through cigarette, compared to existing commercial U-shaped scavenging conduit, the utility model has the ability for purging whole branch Cigarette, cigarette is set sufficiently to purge, it can be achieved to be especially cigarette volatile component the highly sensitive detection for smelling fragrant ingredient.
Description
Technical field
The present invention relates to the scavenging conduits for carrying out purge and trap detection to cigarette.
Background technique
Cigarette smells fragrant ingredient mainly and includes the outer flavoring of this perfume of tobacco, pipe tobacco, the outer flavoring of three paper, one stick and process
The fragrance component that chemical reaction generates occurs.The additional flavors and fragrances composition of cigarette can be reflected by smelling fragrant ingredient not only, but also and tobacco
Inherent organoleptic quality and style be closely related.Analysis cigarette smells fragrant ingredient to reasonable employment raw tobacco material, flavors and fragrances, optimization
Cigarette composition and technique and raising cigarette quality have directive significance.Currently, the preceding place that Studies on Analysis of Flavor Constituents uses in cigarette
Reason is mainly using direct solvent extraction, Simultaneous distillation-extraction and head space technique etc..Wherein direct solvent extracting method, which easily causes, smells
Fragrant ingredient scatters and disappears；Simultaneous distillation-extraction extraction conditions are violent, will lead to Maillard reaction and caramelization aggravation, by-product
It is more；Head space technique includes Dynamic headspace, Static Headspace and solid phase microextraction, has and does not use organic solvent, easy to operate, fast
The advantages that speed, by-product is few, Static Headspace and solid phase microextraction are widely used to flavor Quality Research in tobacco, but static
For head space without enrichment, sensitivity is relatively low, and solid phase microextraction repeatability is bad.Puffing and trapping, that is, Dynamic headspace technique is
The 1970s, mid-term had operation letter by a kind of complex sample pretreatment technology of the research and development such as Bellar and Lichtenber
Single, high sensitivity and the advantages that do not use organic solvent.The detection of fragrant ingredient is smelt especially suitable for cigarette, but due to cigarette shape
The reason of, common scavenging conduit is only capable of purging pipe tobacco.When for the detection of whole branch Cigarette, cigarette or purging cannot be put into
Pipe, or cannot sufficiently be purged.It also include what cigarette auxiliary materials were brought into since smelling fragrant for cigarette not only includes pipe tobacco volatile component
Volatile component, but existing scavenging conduit is not able to satisfy the needs for smelling fragrant ingredient of complete detection cigarette.
Summary of the invention
The present invention provides a kind of scavenging conduit for the detection of cigarette purge and trap, to overcome drawback of the existing technology.
Purpose to realize the present invention, this its main body of scavenging conduit for the detection of cigarette purge and trap is a " u "-shaped pipe,
It is characterized in that the bore of " u "-shaped pipe side tube body is greater than the bore of other side tube body, passes through a circle between the tube body of two sides
Platform shape tube body is connected, and the round type tube body taper is 0.06~0.15.
The technological progress achieved by the present invention:
The U-tube air intake structure of the internal diameter variable diameter of inlet end of the present invention from thick to thin, in the detection of cigarette purge and trap, cigarette
Branch filter stick may be stuck at the truncated cone-shaped tube body of variable diameter, on the one hand play the role of fixed cigarette, another aspect purge gass are to cigarette
Downward active force is generated, makes to contact between cigarette and reducer pipe closer, purge gass can be prevented short-circuit, purge gass can be made all logical
Cigarette is crossed, compared to existing commercial U-shaped scavenging conduit, the present invention has the ability for purging whole branch Cigarette, obtains cigarette
It is detected with sufficiently purging, it can be achieved that being especially to cigarette volatile component and smelling the highly sensitive of fragrant ingredient.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawing.
Embodiment 1: as shown in Figure 1, scavenging conduit of the present invention is a " u "-shaped pipe structure, the pipe of tube body 4 on the right side of the " u "-shaped pipe
Internal diameter is greater than the bore of left side tube body 6, and the bore of right side tube body 4 is outer slightly larger than common cigarette (perimeter is about 24.3mm)
Diameter, the bore of left side tube body 6 are less than common cigarette outer diameter, the rotary table for being located at 4 lower part of right side tube body by one between the tube body of two sides
Shape tube body 1 is connected, and the taper of the truncated cone-shaped tube body 1 is 0.1, and port inner diameter is identical as the bore of right side tube body 4 thereon, under
Port inner diameter is identical as the bore of left side tube body 6, and the present embodiment is particularly suited for the purging of common cigarette.
Embodiment 2: the present embodiment difference from Example 1 is the bore of right side tube body 4 slightly larger than ramuscule cigarette cigarette
The outer diameter of branch (perimeter is about 17.0 mm), the bore of left side tube body 6 are less than the outer diameter of ramuscule Cigarette, and rotary table taper is
0.08, the present embodiment is particularly suited for the purging of ramuscule Cigarette.
After Cigarette 3 is placed in the right side tube body 4 i.e. air inlet port 5 of " u "-shaped pipe, cigarette 3 is pressed lightly on, filter stick 2 is made
End and 1 inside pipe wall of truncated cone-shaped tube body completely attach to, after then pressure ring connection component is connect with 4 upper port of right side tube body, then
Deactivation quartz cotton-wool is filled in the port of left side tube body 6, to prevent offal, clast from entering purge and trap instrument host, then is distinguished
The port of right side 4 upper ports of tube body, that is, purge gass import and left side tube body 6, that is, purge gass outlet is connected respectively to purge and trap
Instrument host, starting purging program, purge gass by right end air inlet port 5 enter scavenging conduit, and all successively via Cigarette 3,
It is flowed out again via left side tube body 6 after the sufficiently purging of filter tip 2.
