Detailed ways

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, in one embodiment of an aerosol generating system, an aerosol generating system includes an aerosol-generating article 100 and an aerosol generating device 200 that cooperates with an aerosol-generating article 100 to contain an aerosol. One end of the article 100 is produced. The aerosol generating device 200 includes a piercing member 210, a heating member 220, a first heat insulating member 230, and a device housing 240. As shown in FIG. 5, the first heat insulating member 230 is provided with a heat insulating member air groove: the second gas The tank 2301 and the third air tank 2302, as shown in FIG. 2, are provided with an air inlet 243 on the apparatus casing 240. As shown in FIGS. 1 and 11, the aerosol-generating article 100 includes a nozzle member 140, an aerosol generating substrate, a carrier 114, and a sealing assembly 110, and the sealing assembly 110 includes a container 111.

An aerosol generating matrix refers to a substance capable of generating an aerosol under certain conditions. For a liquid form of an aerosol generating matrix, it is usually required to evaporate an aerosol generating matrix to form an evaporating substance (for example, a gas) under heating conditions. The evaporant is mixed with air to form an aerosol under certain conditions. The aerosol generating substrate may be smoky oil, and the smoky oil may include glycerin (glycerin), propylene glycol, flavor (or fragrance) and nicotine (nicotine). Among the above-mentioned cigarette oils, nicotine and/or flavor may be derived from tobacco extract. Alternative. Smoke oil may also not contain nicotine.

The carrier 114 is used to carry an aerosol generating matrix (e.g., an aerosol generating matrix in liquid form). As shown in Fig. 8, the carrier 114 has a carrier through hole 1141 for insertion of the piercing member 210. The carrier 114 may be cotton (which may be a high temperature resistant cotton), porous ceramic, glass fiber, or the like, or other porous structure having a certain ability to adsorb liquid.

Seal assembly 110 is used to seal carrier 114 and an aerosol generating substrate carried within carrier 114. Referring to FIGS. 8 to 10, in one embodiment, as shown in FIG. 8, the sealing assembly 110 shown in FIG. 1 includes the above-described container 111 shown in FIG. 1, and the first sealing member 112 shown in FIG. A second seal 113 for containing the carrier 114 and an aerosol generating matrix within the carrier 114. The container 111 includes an upper container unit 1111, a lower container unit 1112, and a sealing layer 115 (in the present embodiment, close to the nozzle member 140), and the upper container unit 1111 and the lower container unit 1112 are cup-shaped with a cup bottom. The upper container unit 1111 is in contact with the lower container unit 1112, and the sealing layer 115 is used to fix the upper container unit 1111 and the lower container unit 1112 together, and seals the gap between the upper container unit 1111 and the lower container unit 1112. To prevent the aerosol generating matrix in the carrier 114 from flowing out of the container 111. The sealing layer 115 may be adhered to the side walls of the upper container unit 1111 and the lower container unit 1112. For example, an adhesive is provided on the side walls of the upper container unit 1111 and the lower container unit 1112 to adhere the sealing layer 115. Even if the adhesive generates an odorous gas at a high temperature, it is difficult for the odor gas to enter the first gas groove 211 and be sucked by the user.

The lower container unit 1112 is provided with a lower opening 1114 and a lower container unit opening 11121. The upper container unit 1111 is provided with an upper opening 1113 and an upper container unit opening 11111. The upper container unit opening 11111 is aligned with the lower container unit opening 11121. The sealing layer 115 seals the gap between the upper container unit opening 11111 and the lower container unit opening 11121. The first end of the carrier through hole 1141 is opposite to the lower opening 1114, and the second end of the carrier through hole 1141 is opposite to the upper opening 1113. The first sealing member 112 is fixed (for example, adhered) to the inner wall of the lower surface of the lower container unit 1112, and covers the lower opening 1114. The second sealing member 113 covers the upper opening 1113. For example, the second sealing member 113 can be fixed on the upper sealing member 113. The outer wall of the container unit 1111 (for example, the outer wall of the upper surface) or the inner wall.

The first seal member 112 and the second seal member 113 are easily pierced by the piercing member 210, and the pierced position may be in a state of being broken, torn, or the like. The first seal 112 and the second seal 113 may be provided with scores such that the first seal 112 and the second seal 113 are easily broken in the direction of the score when pierced by the piercing member 210. The first seal member 112 and the second seal member 113 may be formed of a thin metal layer such as aluminum foil or the like.

The container 111 is preferably a metal container (preferably having a greater thickness than the first seal 112 and the second seal 113, such as an aluminum container) to prevent the container 111 from being heated by the piercing member 210 to melt or generate an aerosol generating matrix and / or an odor other than aerosol. Since the first sealing member 112 is fixed (for example, by adhesive bonding) on the inner wall of the lower surface of the container 111, when the aerosol-generating product 100 is pulled out from the aerosol generating device 200, the first sealing member 112 does not easily fall off and remains in the In the aerosol generating device 200; if the first sealing member 112 is fixed on the outer wall of the container 111, when the aerosol-generating product 100 is used, the first sealing is performed when the aerosol-generating product 100 is pulled out from the aerosol-generating device 200 The piece 112 has a risk of falling off and remaining in the aerosol generating device 200. The above adhesive may be an inorganic adhesive or an organic adhesive (for example, a protein adhesive, a rubber adhesive, a polymer adhesive, etc.). If the first sealing member 112 is adhered to the outer wall of the container 111 by an adhesive, especially an organic adhesive, since the first sealing member 112 and the container 111 are heated by the piercing member 210, the viscosity of the organic adhesive is lowered, and when the aerosol-forming product is produced When the 100 is pulled out from the aerosol generating device 200, the first sealing member 112 is more likely to fall off and remain in the aerosol generating device 200. By sticking the first sealing member 112 to the inner wall of the lower surface of the container 111, even if the first sealing member 112 comes off, it remains in the container 111, so that the aerosol-generating article 100 is pulled out.

As shown in FIG. 5, the sidewall 215 of the piercing member 210 is provided with a first air groove 211. The first air groove 211 may be formed by cutting or the like, or may be formed during the process of casting the piercing member 210. . The first air groove 211 may have a curved shape extending along the surface of the piercing member 210 (for example, spirally rising along the surface of the piercing member 210) or a linear shape, and the first air groove 211 of a curved shape may be first than the linear shape. The gas channel 211 provides greater gas resistance, as the user needs more suction when pumping the aerosol-generating article.

As shown in FIG. 3, in one embodiment, the piercing member 210 is provided with a piercing member cavity 212, and the heating member 220 is disposed within the piercing member cavity 212. The heat generated by the heating member 220 reaches the piercing member through heat conduction. 210 on. In some cases there is a gap between the heating member 220 and the sidewall of the piercing member cavity 212, which may be filled with a thermally conductive material to provide good thermal conduction between the heating member 220 and the piercing member 210. The overall contour of the piercing member 210 may be in the shape of a cylinder, a rectangular parallelepiped, a square or the like, and the top of the piercing member 210 may have a sharp shape such as a cone shape to pierce the first sealing member 112 and the second sealing member 113, and of course pierce the member. The top of 210 may also have no sharp shape.

As shown in Figure 1, the piercing member 210 readily transfers heat to the device housing 240 during use, causing the device housing 240 to become hot. By disposing the first thermal insulation component 230 at the bottom of the piercing component 210 and between the piercing component 210 and the device housing 240, heat transfer to the device housing 240 can be reduced or prevented. As shown in FIG. 5, the outer wall of the first heat insulating member 230 is provided with a second air groove 2301. The upper surface of the first heat insulating member 230 is provided with a third air groove 2302, and the air passes through the second air groove 2301 and the third. The air groove 2302 enters the first air groove 211. In one embodiment, the first thermal insulation component 230 is placed over the bottom of the piercing component 210. The first heat insulating member 230 may be made of ceramic.

Referring to Figures 1, 5 and 8, in use, the piercing member 210 first passes through the lower opening 1113 of the container 111, then pierces the first seal 112, and then inserts the carrier through hole 1141 through the first end of the carrier through hole 1141. Finally, through the upper opening 1113 of the container 111 and piercing the second sealing member 113, the side wall 215 of the piercing member 210 abuts the carrier 114 and heats the aerosol generating matrix in the carrier 114 to cause the aerosol generating matrix to be After heating, evaporation forms an evaporate and enters the first gas tank 211. Air enters through the air inlet 243 (the process of entering the second air tank 2301 will be described in detail later), and then pierced through the second air tank 2301, the third air tank 2302, the lower opening 1113, and the first seal 112. The position enters the first air groove 211 to be mixed with the evaporant into a mixture, and then the mixture enters the nozzle member 140 through the position where the first air groove 211 and the second seal 113 are punctured. The mixture eventually forms an aerosol, and the aerosol may be formed in the first gas channel 211 or downstream of the first gas channel 211 (outside the first gas channel 211).

In the above embodiment, since the piercing member 210 is in close contact with the carrier 114 to heat the aerosol generating substrate in the carrier 114, the heating effect is good, and the first air groove 211 is provided on the side wall of the piercing member 210. The evaporant formed by heating and evaporating the aerosol generating substrate can be driven by the air flowing through the first gas groove 211 to finally form an aerosol. If the piercing member 210 is not in close contact with the carrier 114, the heating effect will be greatly reduced, because the gap between the piercing member 210 and the carrier 114 will pass through the flowing air, thereby taking away more heat, in order to achieve better heating effect. It is necessary to increase the temperature of the piercing member 210, thereby causing a decrease in battery life of the aerosol generating device 200.

A plurality of first air grooves 211 may be disposed on the sidewall of the piercing member 210. Compared to the first air groove 211, the plurality of first air grooves 211 facilitate generating more aerosols at the same time. Correspondingly, a corresponding number of second air grooves 2301 and third air grooves 2302 may be provided, and each of the second air grooves 2301 is in communication with a corresponding one of the third air grooves 2302 and the first air grooves 211. Thus, the air sequentially passes through the second air groove 2301 and the third air groove 2302, and then enters the corresponding first air groove 211.

As shown in FIG. 5, in other embodiments, the bottom side wall of the piercing member 210 further has a fourth air groove 213 extending along the surface of the piercing member 210, and a plurality of first air grooves 211 and a fourth air groove. After the 213 is connected, the air enters the fourth air groove 213 through the second air groove 2301 and the third air groove 2302, and then enters each of the first air grooves 211 respectively. It can be seen that the fourth gas groove 213 functions to distribute air to the different first gas grooves 211. The fourth air groove 213 may extend in a circumferential direction on the bottom side wall of the piercing member 210. The fourth air groove 213 may have an annular shape or an arc shape according to the length. In some embodiments, the first heat insulating member 230 may also have a plurality of second air grooves 2301 (and a corresponding number of third air grooves 2302), and the plurality of third air grooves 2302 communicate with the fourth air grooves 213.
