DETAILED DESCRIPTION OF THE EMBODIMENTS

[0047] The present disclosure will be further described in detail below with reference to the embodiments and drawings. The embodiments are used only to describe the present disclosure, rather than to limit the present disclosure.

[0048] In the following embodiments, the aerosol generating source adopts a vapor producing particle, and the inspection device and method are also applicable to a vapor producing paste.

[0049] The aerosol generating product 3 includes a vapor producing section 31, a blocking member 32, an empty section 34 and a filtering section 33.

Embodiment 1

[0050] This embodiment provides a light inspection method for a quantitative analysis on a filling level of a vapor producing section of an aerosol generating product, including the following steps:

[0051] (1) An aerosol generating product to be inspected is held into a sample holding slot 23, and a light inspection box 2 is provided in front of a surface light source 1. An angle between an axis of the aerosol generating product and a horizontal plane is 90°, and the axis of the aerosol generating product is perpendicular to a horizontal beam emitted by the surface light source 1, as shown in FIGS. 2 and 4.

[0052] (2) The surface light source 1 is turned on, such that the horizontal beam emitted by the surface light source 1 passes through the aerosol generating product held in the light inspection box 2. According to a ratio of a shadow area of an opaque part in the vapor producing section of the aerosol generating product to a shadow area of the vapor producing section, the filling level of the vapor producing section is calculated;

filling level=shadow area of the opaque part in the vapor producing section/shadow area of the vapor producing section*100%.

[0053] Further, a casing 21 is provided with different scales to indicate different filling levels of the vapor producing section, and the filling level of the vapor producing section is determined by a scale corresponding to a horizontal plane of the opaque part in the vapor producing section.

[0054] Intuitively, as shown in FIG. 4, the horizontal beam emitted by the surface light source 1 is from the inside of the paper to the outside of the paper, so the inspector observes the aerosol generating product in the light inspection box 2 from the outside of the paper and perpendicular to the paper.

[0055] A first batch of 12 aerosol generating products was inspected by using the above device. In order to clearly show the structure of the light inspection box 2, FIG. 4 only shows a sample 1-1 (a first sample from top to bottom in a first column, the same below), a sample 1-2 (a second sample from top to bottom in the first column), a sample 2-1 (a first sample from top to bottom in a second column), and a sample 2-2 (a second sample from top to bottom in the second column). It can be seen from FIG. 4 that in the first batch of samples, except for the sample 1-1, the vapor producing sections 31 of other aerosol generating products are fully filled, with a filling level of 100%. According to the scale on the casing 21 of the light inspection box 2, the filling level of the sample 1-1 is accurately 80%.

Embodiment 2

[0056] The light inspection method adopted in this embodiment is the same as that in Embodiment 1, with the following differences: the angle between the axis of the aerosol generating product 3 held in the light inspection box 2 and the horizontal plane is 0°, the horizontal beam emitted by the surface light source 1 passes through the aerosol generating product 3, and the axis of the aerosol generating product is perpendicular to the horizontal beam emitted by the surface light source 1, as shown in FIG. 3. That is, on the basis of Embodiment 1, the light inspection box 2 is directly rotated by 90°, as shown in FIG. 5.

[0057] Intuitively, the same as FIG. 4, as shown in FIG. 5, the horizontal beam emitted by the surface light source 1 is from the inside of the paper to the outside of the paper, so the inspector observes the aerosol generating product in the light inspection box 2 from the outside of the paper and perpendicular to the paper.

[0058] A second batch of 12 aerosol generating products was inspected by using the above device. In order to clearly show the structure of the light inspection box 2, FIG. 5 only shows a sample 1-1 (a first sample from left in a first row, the same below), a sample 1-2 (a second sample from left in the first row), a sample 2-1 (a first sample from left in a second row), and a sample 2-2 (a second sample from left in the second row). It can be seen from FIG. 5 that in the second batch of samples, except for the sample 1-1, the vapor producing sections 31 of other aerosol generating products are fully filled, with a filling level of 100%. According to the scale on the casing 21 of the light inspection box 2, the filling level of the sample 1-1 is accurately 80%.

Embodiment 3

[0059] The light inspection method adopted in this embodiment is the same as that in Embodiment 1, with the following differences: the angle between the axis of the aerosol generating product 3 held in the light inspection box 2 and the horizontal plane is 60°, the horizontal beam emitted by the surface light source 1 passes through the aerosol generating product 3, and the axis of the aerosol generating product is perpendicular to the horizontal beam emitted by the surface light source 1. That is, on the basis of Embodiment 1, the light inspection box 2 is directly rotated by 30°, as shown in FIG. 6.

[0060] Intuitively, the same as FIG. 4, as shown in FIG. 6, the horizontal beam emitted by the surface light source 1 is from the inside of the paper to the outside of the paper, so the inspector observes the aerosol generating product in the light inspection box 2 from the outside of the paper and perpendicular to the paper.

[0061] A third batch of 12 aerosol generating products was inspected by using the above device. In order to clearly show the structure of the light inspection box 2, FIG. 6 only shows a sample 1-1 (a first sample from top to bottom in a first column, the same below), a sample 1-2 (a second sample from top to bottom in the first column), a sample 2-1 (a first sample from top to bottom in a second column), and a sample 2-2 (a second sample from top to bottom in the second column). It can be seen from FIG. 6 that in the third batch of samples, except for the sample 1-1, the vapor producing sections 31 of other aerosol generating products are fully filled, with a filling level of 100%. According to the shadow area, the filling level of the sample 1-1 is calculated as 80%.
