In addition, when the plurality of vent holes are located on the same radial plane of the standard rod, the adjusting mechanism is preferably a rotary adjusting mechanism; the adjustment mechanism is preferably a bayonet-type adjustment mechanism when the plurality of vent holes are located in different radial planes of the modular rod.
Furthermore, the standard rod in the multifunctional airflow distribution standard component is a quartz glass standard rod or a ceramic standard rod, and quartz glass and ceramic are not easily influenced by the environmental temperature, so that the quartz glass standard rod or the ceramic standard rod can reduce the influence of the environmental temperature change on the test result as much as possible, is not easy to age and denature, and prolongs the service life of the standard rod.
Since the capillary in the standard rod in the multifunctional air flow distribution standard leads the air flow from one end to the other end, in order to ensure the accuracy of the test, the laminar state of the air flow is maintained when the air flow passes through the capillary, so the length of the standard rod cannot be too short; if the length of the standard bar is too long, the standard bar is inconvenient to use in ventilation rate detection equipment; and the length of the gauge bar is related to the diameter of the capillary therein. Therefore, the size of the standard rod is consistent with that of the existing cigarette, so that the ventilation rate test state of the cigarette can be more closely approached by adopting the calibration and verification of the ventilation rate test equipment by the ventilation rate standard rod, the standard component can be suitable for cigarette ventilation rate test equipment of different brands and different models, and the standard component has better universality and applicability.
Therefore, the multifunctional airflow distribution standard component provided by the invention expands the application range, can perform verification or calibration work on the indexes of the paper ventilation rate, the filter tip ventilation rate and the total ventilation rate of the cigarette ventilation rate detection equipment by using one standard component, and can perform multi-point verification, calibration or verification work on the indexes of the paper ventilation rate, the filter tip ventilation rate and the total ventilation rate of the cigarette ventilation rate detection equipment by using one standard component, thereby effectively reducing the purchase cost of the standard component.
