Abstract: A light inspection method for a quantitative analysis on a filling level of a vapor producing section of an aerosol generating product is provided. The light inspection method includes: providing a light inspection device for holding an aerosol generating product and a surface light source for emitting a horizontal beam; and an angle between an axis of the aerosol generating product held by the light inspection device and a horizontal plane is 0-90°; the axis of the aerosol generating product held by the light inspection device is perpendicular to the horizontal beam emitted by surface light source. A light inspection device for a quantitative analysis on a filling level of a vapor producing section of an aerosol generating product is further provided. The light inspection device can accurately detect the filling level of a vapor producing section of an aerosol generating product.

Abstract: A multi-purpose internal component for an aerosol-generating product includes a hollow cylinder and air-permeable sealing members located at two ends of the hollow cylinder, where the hollow cylinder is filled with a functional material. The hollow cylinder can be filled with a smoke-generating material, a material with cooling, fragrance-enhancing, and harm-reducing functions, a filter material, and the like, such that multiple functions can be achieved; and the air-permeable sealing members at the two ends enable an air-flow channel. The internal component for an aerosol-generating product is simple and widely used in aerosol-generating products. An aerosol-generating product using the multi-purpose internal component for an aerosol-generating product is provided, where the multi-purpose internal component for an aerosol-generating product can be used as an aerosol-generating component, a multi-functional component, or a filter component.

Abstract: The present disclosure relates to a method and a device for judging gas leakage, and an electronic device. The method includes: acquiring methane concentration data collected by monitoring devices, and generating a first function corresponding to the methane concentration data; acquiring a change rule of methane concentration in an inspection well during biogas accumulation, and generating a second function of the methane concentration changing with time; calculating a first correlation coefficient between the first function and the second function, and judging whether the first correlation coefficient is greater than a first preset threshold; acquiring a third function of gas consumption changing with time if no; and calculating a second correlation coefficient between the first function and the third function, judging whether the second correlation coefficient is less than a second preset threshold, and judging whether the gas leakage occurs based on the methane concentration data if no.

Abstract: A method for filling an aerosol generating product includes: preparing a tube body of the aerosol generating product; filling a filter element into the tube body, wherein the filter element is adjacent to a near-lip end of the tube body; installing a blocking and flow guide element from a far-lip end of the tube body; installing a fuming unit from the far-lip end of the tube body, where the fuming unit is located at the far-lip end of the tube body; and sealing the far-lip end of the tube body, and forming a sealing part on an end face of the far-lip end of the tube body. In the new method, each component is successively filled from the near-lip end to the far-lip end of the aerosol generating product, thereby effectively avoiding the pollution caused by the fuming unit on the tube body during the filling of the fuming unit.
