The atomizing core 20 includes: a base 21 , a base 22 , a liquid guide 23 and a heating element 24 .

As shown in FIG. 7 , the base 21 has a receiving groove, and the base 22 is embedded in the receiving groove of the base 21 . The base 22 is formed with an installation cavity 224, a liquid inlet hole 2211 and a fixing part 2221.

The liquid inlet hole 2211 communicates with the liquid storage chamber 11 and the installation cavity 224, and the aerosol-generating matrix in the liquid storage chamber 11 enters the installation cavity 224 through the liquid inlet hole 2211. Specifically, as shown in Figure 8, the number of liquid inlet holes 2211 can be two, and the two liquid inlet holes 2211 are arranged at intervals to transport the aerosol-generating matrix through the two liquid inlet holes 2211 to ensure liquid supply in the installation cavity 224.

Specifically, as shown in FIG. 9 , the two ends of the heating element 24 are respectively opposite to the two liquid inlet holes 2211 .

As shown in FIG. 8 , the fixed portion 2221 is in contact with the liquid guide member 23 , and the projection of the portion of the fixed portion 2221 that contacts the liquid guide member 23 on the edge of the liquid inlet hole 2211 surrounds the liquid inlet hole 2211 , so that the liquid guide member 2221 is in contact with the liquid guide member 23 . 23 is in close contact with the edge of the liquid inlet hole 2211; so that the liquid guide member 23 at the corresponding position is compressed under the clamping force of the fixed part 2221 and the base 22, reducing the porosity of the liquid guide member 23 , which effectively enhances the liquid-locking ability of the liquid guide member 23 to a certain extent and reduces the leakage amount of the aerosol-generating matrix flowing out through the liquid guide member 23, thereby effectively reducing the probability of liquid leakage in the atomizing core 20. From another angle, if the liquid guide member 23 is used as liquid guide cotton, the fixed part 2221 is in contact with the liquid guide cotton, thereby pressing the liquid guide cotton at the edge of the liquid inlet hole 2211, which can prevent the liquid guide cotton from being heated or soaked in liquid. It becomes fluffy due to factors such as other factors, and reduces the porosity inside the liquid-conducting cotton, improving the liquid-holding ability of the liquid-conducting cotton, thus preventing liquid leakage due to fluffiness or high porosity of the liquid-conducting cotton.

In a specific embodiment, referring to Figure 8, the fixed part 2221 is arranged opposite the liquid inlet 2211 along the radial direction D of the atomization core, and covers the liquid inlet 2211. That is, the liquid inlet 2211 is on the plane where the fixed part 2221 is located. The projection coincides with the fixed part 2221. In this specific embodiment, the entire surface of the portion of the fixing portion 2221 corresponding to the liquid inlet hole 2211 is in contact with the liquid guide 23 . This is to prevent the liquid guide member 23 from bulging and deforming under the impact of the aerosol-generating matrix in the liquid inlet hole 2211.

In another specific embodiment, see FIG. 10 , which is a schematic diagram of the positional relationship between the projection of the fixing part on the plane where the liquid inlet hole is located and the liquid inlet hole according to an embodiment of the present application. The fixing part 2221 is in the shape of a closed ring. The fixing part 2221 is arranged along the periphery of the liquid inlet hole to contact the liquid guide member 23 so that the liquid guide member 23 is in close contact with the edge of the liquid inlet hole 2211 to prevent leakage. liquid.

Specifically, the curvature of the surface of the fixed portion 2221 in contact with the liquid guide 23 is consistent with the curvature of the liquid guide 23 ; and the curvature of the surface of the fixed portion 2221 in contact with the heating element 24 is consistent with the curvature of the heating element 24 . Therefore, the surface of the fixing part 2221 that is in contact with the liquid conducting member 23 and the heating element 24 can be closely attached to the liquid conducting member 23 and the heating element 24 .

Specifically, as shown in FIG. 8 , the number of fixing parts 2221 is also two. The two fixing parts 2221 are provided in one-to-one correspondence with the liquid inlet holes 2211 to compress the liquid guide member 23 and prevent the liquid guide member 23 from becoming loose and causing air leakage. There is a problem that the sol-generating matrix leaks through the liquid-conducting member 23 . Specifically, the two fixing parts 2221 further resist respectively. Connected to both ends of the heating element 24, the heating element 24 is fixed to the liquid guide 23 at the same time, so that the heating element 24 and the liquid guide 23 fit together, and can better contact with the aerosol-generating substrate to mist it. ization, and can also provide support to the liquid-conducting member 23, further preventing the liquid-conducting member 23 from being fluffy and causing a decrease in its liquid-locking ability.

Specifically, the base 22 can be an integral structure or a split structure. In the embodiment of the present application, the base 22 of a split structure is preferred to facilitate the overall assembly of the atomizing core 20 . The base 22 of the separate structure can be the base 22 involved in any of the following embodiments, and its specific structure and function can be found in the following relevant text descriptions.

Please continue to refer to FIG. 8 . The base 22 includes a first base body 221 and a second base body 222 that are oppositely arranged.

Combining FIG. 8 and FIG. 11 , FIG. 11 is a schematic structural diagram from one perspective of the first base provided by an embodiment of the present application. An accommodating groove 2212 is provided on a side surface of the first base body 221 facing the second base body 222. The liquid inlet 2211 is specifically formed on the side wall 2215 of the accommodating groove 2212 of the first base body 221 and is connected with the accommodating groove. 2212 connected. It should be noted that the side wall 2215 of the accommodating groove 2212 refers to the groove wall on the side opposite to the open end of the accommodating groove 2212. The side wall 2215 of the accommodating groove 2212 may be an arc-shaped curved surface. In this embodiment, as shown in FIG. 8 , the liquid guide 23 is specifically received in the accommodating groove 2212 , and is in contact with the side wall 2215 of the accommodating groove 2212 , and covers the liquid inlet hole 2211 , thereby passing the liquid through the inlet hole 2211 . The aerosol-generating matrix flowing from the hole 2211 to the liquid guide member 23 is directed to the side of the liquid guide member 23 away from the liquid inlet hole 2211.

Among them, because the part of the liquid guide 23 that is in contact with the fixed part 2221, under the clamping force of the fixed part 2221 and the base 22, the liquid guide 23 can be prevented from being fluffy, and the porosity of the liquid guide 23 is reduced, which greatly increases the The liquid-locking ability of the liquid-conducting member 23 is reduced, so that the penetration rate of the aerosol-generating matrix into the surrounding area at the position corresponding to the liquid inlet hole 2211 on the liquid-conducting member 23 is slowed down, which easily causes the aerosol-generating matrix to be in the liquid-conducting member 23 uneven distribution, resulting in local dry burning or small aerosol atomization problems.

To this end, in a specific embodiment, as shown in Figure 11, the groove wall of the accommodating groove 2212 is also formed with a number of drainage grooves 2213 on the side surface facing the second base body 222.

The holes 2211 are connected, and each drainage groove 2213 extends along the circumferential direction of the first seat 221 to conduct the aerosol-generating matrix flowing in from the liquid inlet hole 2211 in the circumferential direction of the first seat through capillary force. Drainage, so that the aerosol-generating matrix can spread evenly from the position of the liquid inlet 2211 along the drainage groove 2213 to the surrounding area, so that the aerosol-generating matrix is on the side where the liquid guide 23 contacts the side wall 2215 of the accommodating groove 2212 The surface is evenly distributed and penetrates into the other side surface of the liquid-conducting member 23, thereby improving the uniformity of heating of the aerosol-generating substrate by the heating element 24 and avoiding the problem of burning the aerosol-generating substrate caused by local high temperature.

Specifically, the drainage groove 2213 is formed at least on the side wall 2215 of the accommodation groove 2212 and is connected with the liquid inlet hole 2211 are connected and located between the two liquid inlet holes 2211, so that the aerosol production matrix can penetrate into the heating element 24 more intensively through the liquid guide 23, thereby increasing the atomization rate of the aerosol generation matrix and causing the aerosol to be generated. The matrix can be effectively aerosolized. Of course, in other embodiments, the drainage groove 2213 can also be formed on the side wall 2215 of the accommodating groove 2212 and the groove wall adjacent to the side wall 2215 and extending along the radial direction C of the base 22. It can also be understood as , the drainage groove 2213 can also be formed on the overall groove wall of the accommodation groove 2212 extending along the radial direction C of the base 22; specifically, it can be set according to the position of the area where the heating element 24 covers the liquid guide 23.

In a specific embodiment, please continue to refer to Figure 11. A lower liquid tank 2214 is also formed on the first base 221. The lower liquid tank 2214 is connected with the liquid storage chamber 11 and extends to the position of the liquid inlet 2211 (see Figure 8 ), so that the liquid inlet 2211 communicates with the liquid storage chamber 11 through the lower liquid groove 2214. Specifically, the bottom of the lower liquid tank 2214 along the axial direction C of the base 22 can be slightly lower than the position of the liquid inlet 2211; that is, the liquid inlet 2211 is located on the side wall of the lower liquid tank 2214 close to the liquid guide 23 bottom to reduce the residue of the aerosol-generating substrate in the lower liquid tank 2214; and, the lower liquid tank 2214 and the liquid inlet hole 2211 are arranged in one-to-one correspondence.

As shown in FIG. 8 , the second seat body 222 cooperates with the first seat body 221 to form an installation cavity 224 and an air outlet channel 223 . In a specific embodiment, refer to FIG. 12 , which is a schematic structural diagram of the second base provided from one perspective according to an embodiment of the present application. Two fixing parts 2221 are specifically formed on a side surface of the second base body 222 facing the first base body 221 , and the fixing parts 2221 are arranged opposite to the liquid inlet hole 2211 . After the first base body 221 and the second base body 222 are assembled, as shown in FIG. 8 , the fixing part 2221 is inserted into the accommodating groove 2212 of the first base body 221 to cooperate with the bottom wall of the accommodating groove 2212 for liquid conduction. The member 23 is clamped so that the liquid guide member 23 is in close contact with the circumferential edge of the liquid inlet hole 2211.
