Wherein, liquid feed hole 2211 communicates liquid storage cavity 11 and installation cavity 224, and the aerosol generation substrate in liquid storage cavity 11 specifically gets into in installation cavity 224 through liquid feed hole 2211. Specifically, as shown in fig. 8, the number of the liquid inlet holes 2211 may be two, and the two liquid inlet holes 2211 are arranged at intervals to transport the aerosol-generating substrate through the two liquid inlet holes 2211, so as to ensure sufficient liquid supply in the installation cavity 224 and prevent the heating element 24 from being dried.

Wherein, the central axis of the orthographic projection of the heating element 24 on the base is parallel to the axial direction C of the base. Specifically, as shown in fig. 9, two ends of the heating element 24 are respectively opposite to the two liquid inlet holes 2211.

As shown in fig. 8, the fixing portion 2221 abuts against the liquid guide 23, and a projection of a portion of the fixing portion 2221 abutting against the liquid guide 23 on the edge of the liquid inlet hole 2211 surrounds the liquid inlet hole 2211, so that the liquid guide 23 is in close contact with the edge of the liquid inlet hole 2211; the liquid guiding part 23 at the corresponding position is tightly pressed under the clamping force of the fixing part 2221 and the base 22, so that the porosity of the liquid guiding part 23 is reduced, the liquid locking capacity of the liquid guiding part 23 is effectively enhanced to a certain extent, the amount of liquid leakage of the aerosol generating substrate flowing out through the liquid guiding part 23 is reduced, and the probability of liquid leakage of the atomizing core 20 is effectively reduced.

To prevent deformation of the liquid guide 23 under the impact of the aerosol-generating substrate within the liquid inlet aperture 2211.

In another embodiment, referring to fig. 10, fig. 10 is a schematic view illustrating a position relationship between a projection of the fixing portion on the plane where the liquid inlet hole is located and the liquid inlet hole according to an embodiment of the present disclosure. The fixing portion 2221 is in a closed ring shape, and the fixing portion 2221 is circumferentially arranged along the periphery of the liquid inlet hole by one turn, so that the liquid guide member 23 is tightly contacted with the edge of the liquid inlet hole 2211 by one turn by abutting against the liquid guide member 23, thereby preventing liquid leakage.

Specifically, the curvature of the surface of the fixing portion 2221 in contact with the liquid guide 23 coincides with the curvature of the liquid guide 23; and the curvature of the surface of the fixing portion 2221 contacting the heat generating element 24 coincides with the curvature of the heat generating element 24.

Specifically, the two fixing portions 2221 further abut against two ends of the heating element 24 respectively to fix the heating element 24 to the liquid guiding member 23, so that the heating element 24 is attached to the liquid guiding member 23, and can better contact with the aerosol generating substrate to atomize the aerosol generating substrate, and can also provide a supporting function for the liquid guiding member 23, thereby further preventing the liquid locking capability of the liquid guiding member 23 from being reduced due to fluffiness.

Specifically, the base 22 may be an integral structure or a separate structure, and the base 22 of the separate structure is preferred in the embodiment of the present application, so as to facilitate the integral assembly of the atomizing core 20. The base 22 of the split structure may be the base 22 according to any of the following embodiments, and the specific structure and function thereof may be described in the following text.

With continued reference to fig. 8, the base 22 includes: the first seat 221 and the second seat 222 are oppositely arranged.

With reference to fig. 8 and 11, fig. 11 is a schematic structural diagram of the first base according to an angle of view according to an embodiment of the present application. A receiving groove 2212 is formed on a side surface of the first base 221 facing the second base 222, and the liquid inlet hole 2211 is specifically formed on a side wall 2215 of the receiving groove 2212 of the first base 221 and is communicated with the receiving groove 2212. Note that the side wall 2215 of the receiving groove 2212 refers to a groove wall on a side opposite to the open end of the receiving 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 guiding member 23 is specifically accommodated in the accommodating groove 2212, contacts with the side wall 2215 of the accommodating groove 2212, and covers the liquid inlet hole 2211, so as to guide the aerosol-generating substrate flowing to the liquid guiding member 23 through the liquid inlet hole 2211 to the side of the liquid guiding member 23 away from the liquid inlet hole 2211.

Because the liquid guide 23 is abutted by the fixing portion 2221, under the clamping force of the fixing portion 2221 and the base 22, the liquid guide 23 can be prevented from being fluffy, the porosity of the liquid guide 23 is reduced, and the liquid locking capability of the liquid guide 23 is greatly increased, so that the permeation speed of the aerosol generating substrate to the surrounding area at the position of the liquid guide 23 corresponding to the liquid inlet hole 2211 is reduced, which easily causes the aerosol generating substrate to be unevenly distributed on the liquid guide 23, thereby causing the problem of local dry burning or small aerosol atomization amount.

For this reason, in an embodiment, as shown in fig. 11, a plurality of drainage grooves 2213 are further formed on a side surface of a groove wall of the receiving groove 2212 facing the second seat body 222, the plurality of drainage grooves 2213 are communicated with the liquid inlet hole 2211, and each drainage groove 2213 extends along the circumferential direction of the first seat body 221, and is used for draining the aerosol-generating substrate flowing from the liquid inlet hole 2211 in the circumferential direction of the first seat body by using a capillary force, so that the aerosol-generating substrate can be uniformly diffused from the position of the liquid inlet hole 2211 to the surrounding area along the drainage groove 2213, so that the aerosol-generating substrate is uniformly distributed on a side surface of the liquid guide 23 contacting with the side wall 2215 of the receiving groove 2212 and penetrates into the other side surface of the liquid guide 23, thereby improving the heating uniformity of the aerosol-generating substrate by the heating element 24, and avoiding a problem that the aerosol-generating substrate is burned due to local high temperature.

Specifically, the drainage groove 2213 is at least formed on the side wall 2215 of the containing groove 2212, is communicated with the liquid inlet holes 2211, and is located between the two liquid inlet holes 2211, so that the aerosol-generating substrate can penetrate onto the heating element 24 more intensively through the liquid guide member 23, thereby improving the atomization rate of the aerosol-generating substrate, and enabling the aerosol-generating substrate to be atomized effectively. Of course, in other embodiments, the flow-guiding groove 2213 can also be formed on the side wall 2215 of the receiving slot 2212 and the groove wall adjacent to the side wall 2215 and extending in the radial direction C of the base 22, and it can also be understood that the flow-guiding groove 2213 can also be formed on the entire groove wall of the receiving slot 2212 extending in the radial direction C of the base 22; specifically, the position of the heating element 24 covering the liquid guide 23 may be set.

In one embodiment, referring to fig. 11, the first base 221 further has a lower liquid groove 2214 formed thereon, and the lower liquid groove 2214 is connected to the liquid storage cavity 11 and extends to the position of the liquid inlet 2211 (see fig. 8), so that the liquid inlet 2211 is connected to the liquid storage cavity 11 through the lower liquid groove 2214. Specifically, the bottom of the lower liquid groove 2214 may be slightly lower than the position of the liquid inlet hole 2211 along the axial direction C of the base 22; that is, the liquid inlet aperture 2211 is located in the lower liquid slot 2214 near the bottom of the side wall of the liquid guide 23 to reduce residue of aerosol-generating substrate in the lower liquid slot 2214; and, the lower liquid grooves 2214 are provided in one-to-one correspondence to the liquid inlet holes 2211.

As shown in fig. 8, the second seat 222 and the first seat 221 cooperate to form a mounting cavity 224 and an air outlet passage 223. In an embodiment, referring to fig. 12, fig. 12 is a schematic structural view of a second base provided in an embodiment of the present application from a viewing angle. The two fixing portions 2221 are specifically formed on a side surface of the second base 222 facing the first base 221, and the fixing portions 2221 are disposed opposite to the liquid inlet holes 2211. After the first seat 221 and the second seat 222 are assembled, as shown in fig. 8, the fixing portion 2221 is inserted into the receiving groove 2212 of the first seat 221 to cooperate with the bottom wall of the receiving groove 2212 to clamp the liquid guide 23, so that the liquid guide 23 is in close contact with the circumferential edge of the liquid inlet 2211.

In an embodiment, as shown in fig. 12, the second housing further includes a connecting portion 2222, the two fixing portions 2221 extend along the axial direction C of the base and are connected by the connecting portion 2222, the connecting portion 2222 and the two fixing portions 2221 cooperate to define a groove 2224, and the groove 2224 extends along the axial direction C of the base 22. The connecting portion 2222 forms a bottom wall of the groove 2224, and the two fixing portions 2221 form side walls of the groove 2224.

Specifically, referring to fig. 8, after the second seat body 222 and the first seat body 221 are assembled, the groove 2224 defined by the second seat body 222 and the liquid guide member 23 cooperate to form an air outlet passage 223, and the aerosol formed by atomization in the installation cavity 224 specifically flows out through the air outlet passage 223 for the user to suck.

In this embodiment, the two fixing portions 2221 are located at two sides of the air outlet passage 223 along the direction C perpendicular to the air outlet path of the air outlet passage 223, so as to avoid the fixing portions 2221 from obstructing the air outlet path, so that the aerosol can smoothly enter the aerosol passage 13, and ensure smoother airflow. Of course, it can be understood that the number of the fixing portions 2221 is one, and the fixing portions 2221 are disposed at one side of the air outlet passage 223.

Specifically, as shown in fig. 8, the second seat 222 is hollow, and the sidewall of the second seat 222 facing the first seat 221 is protruded towards the first seat 221 to form two fixing portions 2221.
