The test method for resisting cigarette burning comprises the following steps: wiping the surface of the test piece with absorbent gauze, and placing the test piece at a wind-sheltered position. One cigarette in the range specified in the standard was taken out and ignited, after burning 10mm in air, the burning cigarette was laid flat on the surface of the test piece for 60 + -5 seconds, and the cigarette was removed. Then sucking about 10mm, horizontally placing on another point of the surface of the test piece, and removing the cigarette after 60 +/-5 s. The distance between the three test points is not less than 50mm, and if the cigarette is extinguished midway, the points are selected again for inspection. The surface of the test piece was scrubbed with cotton dipped in ethanol at a depression angle of 45 degrees under natural light at a distance of about 800mm, and the surface of the test piece was observed from all directions. Two other cigarettes of the specified range were selected and the same test was performed on each of the remaining two cigarettes. The middle of the three test pieces is used to indicate the smoke burn resistance.

When testing 3 grades of cigarettes for one veneer board, a tester takes one cigarette to light and burn off 10mm, then puts the burning cigarette on the surface of the test piece, and if the cigarette is extinguished midway, the point selection test is needed again.

The artificial board stickers are different, and the cigarette burning resistance performance is possibly different, so the test is very frequent, and in order to replace manual smoking and simulate the slow cigarette burning effect of the manual smoking, a cigarette burning resistance test auxiliary smoking component needs to be developed to meet the requirement of frequent tests.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1-2, the auxiliary member comprises a hollow circular tube 1, the diameter of the hollow circular tube 1 is 8mm-12mm, and preferably, the diameter of the hollow circular tube 1 is 10 mm. The hollow circular tube 1 is formed in a shape of a spiral of a spring having a diameter equal to each turn, and the diameter of the spiral is 100cm to 250cm, preferably 150 cm. The two ends of the hollow circular tube are respectively positioned at the two ends of the spiral shape, and the arrangement is so that the inside of the hollow circular tube has enough airflow revolution length in the test process. Preferably, the two ends of the hollow circular tube are aligned up and down, i.e. aligned in the up and down direction of the spiral spring, i.e. the number of turns of the spiral spring hollow circular tube 1 is an integer.

Of the two ends of the hollow circular tube, the first end 11, i.e. the lower end as shown in fig. 1, is fixedly connected with a metal mouthpiece 2, and the metal mouthpiece 2 is fixedly connected with a cigarette, i.e. the cigarette 10 used for the cigarette burning resistance test. The second end 12, i.e. the upper end as shown in fig. 1, of the hollow round tube 1 is open. The hollow round tube is filled with gas for maintaining the continuous combustion of the cigarette. The number of turns of the spring spiral is 3-5, the number of turns is too small, a compressed gas path introduced into the hollow circular tube is small, stable negative pressure cannot be formed, the number of turns is too large, gas flowing resistance is too large, and resistance at the second end cannot be larger than resistance at the first end and at the cigarette holder.

And preferably, a sealant is further provided between the first end 11 and the metal mouthpiece 2 for sealing, for example, the sealant is a silicone sealant, which can be used for fixing the metal mouthpiece 2 and the hollow circular tube 1 as well as sealing.

Preferably, an opening 13 is provided at a position of the metal mouthpiece 2 of the first end 11, which is spaced by one and a half circles from the metal mouthpiece 2, that is, the first end 11, and at two ends of the metal mouthpiece 2, which are located at the same diameter, wherein the opening 13 is used for inserting a gas pipe 3, and the diameter of the gas pipe 3 is smaller than that of the hollow circular pipe 1, for example, the diameter is 6mm in this embodiment. The air pipe 3 is used for introducing compressed air into the hollow circular pipe 1, the compressed air is air commonly used by furniture production enterprises, and the air pressure is more than 5bar, preferably 6 bar. The inserted opening 13 of the air tube 3 divides the hollow circular tube 1 into two parts, one part is used for generating negative pressure, namely between the opening 13 and the second end 12, and the other part is used for generating slow air flow, namely between the opening 13 and the first end 11, so that the slow air flow can provide uniform air flow for burning the cigarettes.

The direction of insertion in the air tube 3, i.e. the air flow, is directed towards a second end 12 opposite to the first end 11 where the metal mouthpiece 2 is located, as indicated by the arrow in figure 2. The compressed gas flows towards the outlet of the hose, namely the direction of the second end, the second end is positioned above, so that the positive pressure is reduced by the high-speed airflow at the upper half part in the hose to form negative pressure, slow airflow is formed at the lower half part of the hollow circular tube, the size of the slow airflow is related to the high-speed airflow at the upper half part, namely the size of the negative pressure at the upper half part, and the slow airflow can continuously and uniformly burn the cigarette at the first end, so that the cigarette cannot be burnt too fast or too slow, and the aim of uniform burning is fulfilled. The air tube 3 is inserted at positions spaced 1-2 circles apart from the first metal mouthpiece 2. Preferably, as shown in fig. 1, it is a half turn, i.e. a turn located above the metal mouthpiece 2 and at two end positions diametrically spaced from the metal mouthpiece.

As shown in fig. 1 and 2, the first end is at the bottom and the second end is at the top, although those skilled in the art will also appreciate that the first end may be at the top and the second end at the bottom. Also the direction of the compressed gas is still downwards towards the second end.

This resistant experimental auxiliary component of cigarette burning, through let in compressed gas in the cavity pipe that the spiral encircleed, the cavity pipe that encircles with the spiral falls into two parts, form slow air current with the opposite one end of gas flow direction, and then supplementary cigarette on the metal cigarette holder that this end set up can the homogeneous combustion, and then be arranged in resistant cigarette burning test, avoid frequently lighting a cigarette and the effect that the cigarette burning was maintained to the people smoking, and then experimental efficiency has been improved, and experimental success rate and rate of accuracy have also been improved.

Although the preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that modifications and variations of the present invention are possible to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
