RU197817U1 - DEVICE FOR CONNECTING ELECTRICAL SYSTEMS FOR HEATING GLO TOBACCO WITH LINEAR LABORATORY SMOKING MACHINE - Google Patents

Abstract

The utility model relates to the tobacco industry and is intended for use in research laboratories. The device is a lodgement plate, by means of which the positioning and connection of GLO tobacco electric heating systems with the channels of a Cerulean SM450 linear type smoking machine is made to collect the aerosol obtained by heating GLO sticks, determine the content of carbon monoxide and various toxic substances.

Description

The proposed utility model relates to the tobacco industry and is intended for use in research laboratories.

For the analysis of tobacco vapor during the collection of the gas phase of the aerosol of nicotine-containing products (NSP), the multichannel smoking machine SM450 of the linear type from Cerulean (Great Britain) is known, which provides various modes of collecting the aerosol of NSP. The method of collecting aerosol on this laboratory smoking machine complies with GOST R 57458-2017 “Heated tobacco. General specifications "for the voluntary certification of heated tobacco sticks (sticks) by manufacturers. Each channel of the smoking machine has cigarette holders and traps with labyrinth seals for collecting the solid-liquid phase of the aerosol, bags for collecting the gas phase of the aerosol.

A smoking machine is used to study electrical systems for heating tobacco (ESNT) - carbon monoxide and collecting the solid-liquid phase of the aerosol on the filter for further gas chromatographic analysis of the components. Along with holders for cigarettes, there are special brackets for laying a certain type of cylindrical single-sided power transformer. However, these brackets do not provide an aerosol collection process with GLO ESST, since the electric heating systems of GLO tobacco are rectangular in shape, with an eccentric stick arrangement, with an internal heating element. These systems for heating tobacco do not mate with the channels of the smoking machine, either using the existing cigarette holders or using the existing brackets to hold the cylindrical-shaped single-sided tubes.

The goal is to develop a device that interconnects ESNT GLO with the channels of a smoking machine for smoking and further gas chromatographic analysis of the content of components of an ESNT aerosol, as well as ESNT carbon monoxide.

The technical result of the proposed utility model is the positioning and connection of ESNT GLO sticks with holders of traps of a smoking machine entering the channel of a smoking machine.

This result is achieved by adding to the existing system of brackets a device for interfacing electric heating systems of GLO tobacco with a linear laboratory type smoking machine, which is a lodgement plate, the thickness and configuration of which allows them to be positioned relative to channels with labyrinth seals of smoking machine traps. The lodgement plate is placed in the brackets of the smoking machine, while at the bottom it has a shape and seats for existing brackets, and on top it has a shape and seats for a GLO single-sided wall and can be made in the form of a single structure, or from several components.

In FIG. 1 shows a device for interfacing a GLO ECST with a smoking machine, FIG. 2 - also, a top view.

The device consists of a lodgement plate repeating from below the shape of existing brackets, with a seat size for an arm c = 26 mm and a step for arranging seats for a brackets a = 38 mm, and on top having seats for electric tobacco heating systems (ЭСНТ GLO) of size b = 38.5 and the pitch of their location d = 25.5. The lodgement plate can be made unified on all 20 channels of the smoking machine, or from components.

The device operates as follows. Before starting work on the smoking machine, the brackets are installed in the channels (slots) selected for the work in the quantity necessary for scrolling the planned number of GLO SWNTs (or all brackets in the case of a single lodgement plate). Then, on the brackets, the bottom side is installed a plate - a lodgement. Ready-to-operate ESNT devices with sticks installed in them are placed in the upper part of the cradle plate. The thickness and configuration of the lodgement plate makes it possible to position the GLO ESNT in such a way that the sticks installed in them are precisely centered along the channels with labyrinth seals of the traps for collecting the aerosol of the smoking machine. ESNT GLO devices are fixed in the recesses of the lodgement plate, which allows you to press the device activation button without risk moving them relative to the trap to collect the aerosol with loss of tightness or loss of the stick with the device from the trap. The aerosol is collected to obtain data on the content of the components of the aerosol sticks and to determine the solid-liquid and gas (carbon monoxide) phases of the aerosol by toxic chromatographic analysis of toxic substances.

A device for interfacing electrical systems of heated tobacco with a linear-type laboratory smoking machine Cerulean SM450 was manufactured and tested in the laboratory of chemistry and quality control of FGBNU VNIITTI and showed positive results.
