Background

With the pursuit of upgrading healthy life, people pay more attention to physical and mental health and environmental protection, so that the development of the traditional cigarette is more and more restricted. The cigarette product which is not burnt after being heated is produced in order to adapt to and meet psychological and physiological requirements of consumers, and the cigarette product is a novel tobacco product which enables tobacco materials to generate a smoke releasing effect by means of heating, so that tobacco is heated only at a lower temperature (generally lower than 500 ℃), tar and a large amount of harmful compounds caused by high-temperature combustion of the tobacco are avoided, and as side-stream smoke is basically not generated, the cigarette product can not influence the public environment while meeting the physiological requirements of the smoke of the consumers, and becomes the key direction for developing more and more tobacco manufacturing enterprises and research institutions.

The obtained smoke amount is an important index which directly influences the physiological satisfaction of consumers and is also a reference for measuring the quality of the cigarette products which are not combusted by heating. In the tobacco industry, indexes such as smoke release amount and the like of traditional cigarette products are tested in a mode of fixing smoking volume by a smoking machine for quality evaluation, and a certain effect is achieved. However, no device for testing the smoke emission of the cigarette which is not burnt by heating exists at present.

Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Referring to fig. 1, the embodiment discloses an experimental device for measuring the release amount of particulate matters in smoke of a heated non-combustible cigarette, the experimental device is used for measuring a cigarette 2 in a heated non-combustible smoking set 1, the experimental device comprises a cigarette holder 3, a gas pool 4 and a vacuum pump 5, the gas pool 4 can be made of a glass box, and the volume of an inner cavity of the gas pool 4 can be set to be 30 ml-50 ml. The outer side of the gas pool 4 is provided with a vacuumizing port and a suction port, the outside of the vacuumizing port is connected to a vacuum pump 5 through a vacuumizing pipeline 6, the outside of the suction port is connected to a cigarette holder 3 through a suction pipeline 7, the vacuumizing pipeline 6 is provided with a first electric valve 8 and a pressure sensor 9, the suction pipeline 7 is provided with a second electric valve 10, a clamping channel for clamping cigarettes 2 is arranged in the cigarette holder 3, a Cambridge filter disc is placed in the clamping channel, and the top of the clamping channel is communicated with the suction pipeline 7.

The pressure sensor 9 is used for detecting the vacuum degree inside the gas pool 4 and controlling the opening and closing of the two electric valves and the vacuum pump 5 according to the vacuum degree signal detected by the pressure sensor 9.

The experimental device provided in this example was used as follows:

before the experiment, the experimental device is assembled according to the figure 1, the Cambridge filter disc is placed in the clamping channel of the smoking set clamp holder, and then the top of the cigarette 2 in the heating non-combustion smoking set 1 is clamped in the clamping channel of the smoking set clamp holder.

In the experiment, first, the second electric valve 10 is closed, the first electric valve 8 is opened, the suction pipeline 7 is not communicated, and the vacuumizing port of the gas pool 4 is communicated with the vacuum pump 5 through the opened first electric valve 8. And then, starting the vacuum pump 5 according to the pressure parameters set by the controller to vacuumize the gas pool 4, detecting the vacuum degree in real time by the pressure sensor 9, and closing the first electric valve 8 after the vacuum degree meets the set requirement. Preheating a heating non-combustion smoking set 1 containing cigarettes 2 connected in advance, opening a second electric valve 10 to enable a suction port of a gas pool 4 to be communicated with the cigarettes 2 through a suction pipeline 7, and sucking smoke by means of the vacuum of the gas pool 4 and the external atmospheric pressure difference; when the pressure sensor 9 detects that the pressure in the gas pool 4 is equal to the external atmospheric pressure, the second electric valve 10 is closed, so that the gas pool 4 is not communicated with the cigarettes 2, and one opening of suction is completed.

And repeating the operations to perform the second suction and the third suction until the smoke suction of the cigarette 2 is finished, thus finishing the suction process of the cigarette 2. And then taking off the Cambridge filter disc for weighing, and subtracting the weight difference obtained by the weight before detection from the weight after the Cambridge filter disc is detected to obtain the release amount of the smoke particle phase substances of the cigarettes 2 under the corresponding set suction pressure.

The applicant heats and sucks a smoking set A which is not heated and burns for a certain brand and a cigarette 2 matched with the smoking set A, and measures the release amount of smoke particulate matters of the cigarette 2 under different vacuum degrees, namely different suction pressures. The applicant measures five cigarettes 2 altogether, and the vacuum degrees in the gas pool 4 corresponding to the five cigarettes 2 are respectively: 950mbar, 850mbar, 750mbar, 650mbar, 550mbar and 450mbar, the suction pressure can be obtained by subtracting the vacuum degree from the standard atmospheric pressure, and the standard atmospheric pressure value is 1000mbar, so that the corresponding suction pressures under the five vacuum degrees are 50mbar, 150mbar, 250mbar, 350mbar, 450mbar and 550mbar respectively. Fig. 2 shows the measurement results of the release amount of particulate matters in smoke of a cigarette 2 under five different suction pressures, wherein TPM in the smoke is a short for the particulate matters in the smoke.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
