Referring to fig. 2 to 5, the atomizing core 40 includes an atomizing housing 41, a heat generating member 43 and a sealing member 45. The atomizing housing 41 has a mounting cavity 418 and an atomizing cavity 4141 located on one side of the mounting cavity 418, the heat generating member 43 is accommodated in the mounting cavity 418, and the sealing member 45 circumferentially covers the heat generating member 43 to limit the heat generating member 43 in the mounting cavity 418. One end of the atomizing chamber 4141 communicates with the mounting chamber 418, and the other end of the atomizing chamber 4141 away from the mounting chamber 418 communicates with the exhaust passage 21 of the housing 20. The heat generating member 43 may absorb and heat the aerosol-generating substrate, and aerosol generated by thermal atomisation of the aerosol-generating substrate may flow from the mounting cavity 418 and then through the atomising cavity 4141 into the air outlet passage.

In some embodiments, the atomizing housing 41 includes a heat-generating base 412, a support 414, and a seal cap 416 that mate with each other.

As shown in fig. 6, specifically, the heating base 412 is a rotor-shaped structure with a central axis extending along a third direction, and includes a bottom wall and a side wall surrounding the edge of the bottom wall, the central area of the bottom wall protrudes toward the exhaust channel 21 to form a liquid inlet portion 411, and a bottom liquid storage cavity 23 for storing aerosol-generating substrate is opened on a side surface of the liquid inlet portion 411 facing the exhaust channel 21.

Further, the liquid inlet portion 411 is further opened with two thimble mounting holes 4114, and the two thimble mounting holes 4114 are disposed at an interval in the second direction. Referring to fig. 4, the atomizing assembly 100 further includes a positive thimble 60 and a negative thimble 70, one end of the positive thimble 60 and one end of the negative thimble 70 are connected to a power supply assembly, and the other end of the positive thimble 60 and the other end of the negative thimble 70 penetrate through the thimble mounting hole 4114 along a third direction and are electrically connected to the heat generating component 43 to supply power to the heat generating component 43.

With continued reference to fig. 3, 4 and 5, the supporting member 414 is a substantially revolving-body-shaped structure with a central axis extending along a third direction, the supporting member 414 is coupled to one end of the heat-generating base 412 having the liquid inlet 411 along the third direction, one axial end of the supporting member 414 and the heat-generating base 412 together define a mounting cavity 418 for accommodating the heat-generating component 43, the other axial end of the supporting member 414 forms an atomizing cavity 4141 communicating with the mounting cavity 418, and the exhaust passage 21 of the housing 20 can be coupled to one side of the supporting member 414 away from the heat-generating base 412 to communicate with the atomizing cavity 4141.

Further, the supporting member 414 defines two liquid drainage channels 4143, the two liquid drainage channels 4143 are spaced apart from each other on two opposite sides of the mounting cavity 418 and the atomizing cavity 4141 in the second direction, one end of each liquid drainage channel 4143 is communicated with the liquid storage cavity 23 of the housing 20, and the other end extends toward the bottom liquid storage cavity 23 of the heat generating base 412 in the third direction. In this manner, aerosol-generating substrate stored in the reservoir 23 may flow into the bottom reservoir 23 through the downcomer channel 4143.

As shown in fig. 4 and fig. 6, in a preferred embodiment, the bottom wall of the bottom liquid storage chamber 23 formed on the liquid inlet portion 411 of the heat generating base 412 is formed with a bottom liquid guiding groove 4116, and the bottom liquid guiding groove 4116 is correspondingly communicated with the liquid outlet channel 4143, so as to guide the aerosol generating substrate flowing out from the liquid outlet channel 4143 to other areas of the bottom liquid storage chamber 23. In one embodiment, one end of bottom fluid guiding groove 4116 is correspondingly connected to one of the fluid passages 4143, and the other end of bottom fluid guiding groove 4116 extends along the second direction to be correspondingly connected to the other fluid passage 4143. In this manner, aerosol-generating substrate in the reservoir 23 flows into the opposite ends of the bottom reservoir 23 in the second direction through the two lower channels 4143 spaced apart in the second direction and then flows along the bottom fluid guide groove 4116 to the central position of the bottom reservoir 23 for absorption by the heat generating member 43.

In some embodiments, the bottom wall of the bottom liquid storage chamber 23 is further protruded with a plurality of liquid guiding columns 4118 surrounding the bottom liquid guiding groove 4116, and a liquid guiding gap is formed between adjacent liquid guiding columns 4118. In this manner, aerosol-generating substrate in the bottom reservoir 23 ascends along the drainage post 4118 into the heat generating member 43 of the mounting cavity 418 by capillary forces between adjacent drainage posts 4118.

As shown in fig. 2, 3 and 4, the sealing cap 416 covers an end of the supporting member 414 far from the heat-generating base 412 in the third direction, so as to close a gap between the heat-generating base 412 and the liquid storage chamber 23, and a communication hole is formed in the sealing cap 416 to communicate the liquid storage chamber 23 with the lower liquid passage 4143, the atomizing chamber 4141 and the air discharge passage 21. In a preferred embodiment, the sealing cap 416 is made of a material that can generate elastic deformation, such as silicone, so as to have a better sealing effect.

The heating member 43 has a cubic structure, the width direction of the heating member 43 extends along a first direction, the length direction of the heating member 43 extends along a second direction, and the height direction of the heating member 43 extends along a third direction. The heating element 43 is limited in the installation cavity 418 defined by the heating base 412 and the support element 414 together through the sealing element 45, the upper surface of the heating element 43 facing to the atomizing cavity 4141 forms an atomizing surface 432 capable of generating heat, the length of the atomizing surface 432 in the second direction is greater than that in the first direction, and the lower surface of the heating element 43 facing to the heating base 412 is communicated with the bottom liquid storage cavity 23 of the liquid inlet 411. In this way, the heat generating member 43 can absorb the aerosol-generating substrate from the bottom liquid storage chamber 23 of the liquid inlet portion 411, and the aerosol-generating substrate generated by heating the aerosol-generating substrate flows out through the atomizing surface 432.

As shown in fig. 2, 3 and 5, one end of the sealing member 45 is coupled to the heat generating base 412, and the other end of the sealing member 45 circumferentially covers the heat generating member 43, and is configured to form an air outlet opening exposing the atomizing surface 432 and an air inlet opening exposing one side surface of the heat generating member 43 facing the bottom reservoir 23. In this way, aerosol-generating substrate in the bottom reservoir 23 can enter the heat generating member 43 through the inlet opening, and aerosol generated by thermal atomization of aerosol-generating substrate in the heat generating member 43 can flow out of the atomization surface 432 through the outlet opening.

Further, in order to increase the liquid guiding speed, a side liquid guiding channel communicated with the bottom liquid storage cavity 23 is formed between the sealing member 45 and the heat generating member 43. So, partly aerosol generation substrate in bottom liquid storage cavity 23 passes through the feed liquor opening of sealing member 45 and gets into in the piece 43 that generates heat from the lower surface of piece 43 that generates heat, and another part aerosol generation substrate then gets into in the piece 43 that generates heat from the side direction through the lateral part drain channel to guaranteed the speed that aerosol generation substrate got into the piece 43 that generates heat, effectively prevented to generate heat piece 43 and sharply rise temperature because of lacking aerosol generation substrate, then prevent to generate heat piece 43 and produce harmful gas and burnt flavor that produce dry combustion method, effectively improved aerosol generation device's use experience.

As a preferred embodiment, a plurality of lateral liquid guiding channels are formed between the sealing member 45 and the heat generating member 43, a lateral liquid guiding channel communicated with the bottom liquid storage chamber 23 is formed between the sealing member 45 and the heat generating member 43, and each lateral liquid guiding channel extends along the third direction.

Referring to fig. 8, in some embodiments, the inner sidewall of the sealing member 45 is provided with a lateral liquid guiding groove 4523a, and a groove wall of the lateral liquid guiding groove 4523a and a sidewall of the heat generating member 43 define together to form a lateral liquid guiding channel, so that the shape of the heat generating member 43 does not need to be modified. In other embodiments, a groove may be formed on the sidewall of the heat generating member 43 to form a side liquid guiding channel.

Further, one end of the sealing element 45 close to the bottom liquid storage cavity 23 is provided with a circumferential liquid guide groove 4523b which circumferentially surrounds the heating element 43, and the circumferential liquid guide groove 4523b is communicated with the bottom liquid storage cavity 23 and the side liquid guide channel. In this manner, aerosol-generating substrate in the bottom reservoir 23 can pass through the circumferential liquid channel 4523b into the lateral liquid channel, thereby ensuring lateral liquid guiding rates.

In some embodiments, the atomizing surface 432 protrudes beyond at least a portion of the edge of the air outlet opening of the seal 45. Thus, the sealing member 45 is not completely covered on the edge of the atomizing surface 432 of the heat generating member 43, and the condensed liquid formed by the aerosol generated after the aerosol generating substrate is heated and atomized when cooled does not gather on the atomizing surface 432, but flows out from the edge of the atomizing surface 432 protruding out of the air outlet opening, so that the aerosol can smoothly flow out from the atomizing surface 432, and the smoke output of the aerosol generating substrate flowing out is ensured.

Specifically, the seal 45 includes a seal body 452 and a bridge 454, and the seal body 452 includes a first seal portion 4521 and a second seal portion 4523. The first sealing portion 4521 covers the liquid inlet portion 411 of the heat generating base 412, the second sealing portion 4523 is connected to one end of the first sealing portion 4521 and circumferentially covers the heat generating member 43, and an edge of one end of the second sealing portion 4523, which is far away from the first sealing portion 4521, is lower than the atomizing surface 432 of the heat generating member 43, so that the atomizing surface 432 protrudes beyond an edge of the second sealing portion 4523 in the third direction. One end of the overlapping portion 454 is connected to one end of the second sealing portion 4523 away from the liquid inlet portion 411, and the other end of the overlapping portion 454 overlaps the edge of the atomizing surface 432.

Thus, the liquid inlet opening is formed at one end of the sealing body 452 away from the overlapping portion 454, the air outlet opening exposing the atomizing surface 432 is formed at one end of the sealing body 452 connected with the overlapping portion 454 and the overlapping portion 454, and the condensate on the atomizing surface 432 of the heating element 43 can flow out from between the two overlapping portions 454. In a preferred embodiment, the atomizing surface 432 protrudes from the edge of the seal body 452 by a distance H1 (shown in FIG. 3) of 0.1mm to 1.5.

It will be appreciated that the lateral fluid channel 4523a opens into the second seal portion 4523 of the seal body 452. In order to prevent the aerosol-generating substrate from flowing out of the mounting cavity 418 through the side channel, the side channel 4523a extends from the end of the seal body 452 remote from the nebulizing chamber 4141 to a portion of the edge of the seal body 452 that connects to the bridge 454. As such, the bridge 454 may act as a barrier to aerosol-generating substrate flowing along the third direction from the atomising surface 432, preventing aerosol-generating substrate from flowing out of the mounting cavity 418 via the side liquid conducting channels.

As shown in fig. 3, 6 and 7, in some embodiments, in order to make the airflow enter the atomizing core 40 and carry the aerosol to flow into the atomizing chamber 4141, a partial area of the bottom wall of the heating base 412 protrudes toward the reservoir 23 to form an air inlet portion 413, and an air inlet hole 4132 communicated with the external environment is opened at one end of the air inlet portion 413 facing the reservoir 23. The supporting member 414 is provided with an air inlet channel 4145, one end of the air inlet channel 4145 is communicated with the mounting cavity 418, and the other end of the air inlet channel 4145 extends back to the mounting cavity 418 along the first direction until the air inlet hole 4132 communicated with the air inlet part 413. In this way, air in the external environment can flow into the air inlet channel 4145 through the air inlet hole 4132, then flow to the installation cavity 418 along the air inlet channel 4145, and then flow into the air outlet channel 21 through the atomizing cavity 4141 with the aerosol generated by the atomizing surface 432.

Specifically, in some embodiments, the sealing member 45 includes two overlapping portions 454, and the two overlapping portions 454 are respectively connected to two opposite sides of the sealing member main body 452 in the second direction, so that the atomizing surface 432 protrudes from two opposite side edges of the air outlet opening in the first direction. The heat generating base 412 forms two air inlet portions 413 arranged at intervals in the first direction, the support 414 is provided with two air inlet channels 4145, the two air inlet channels 4145 are respectively arranged on two opposite sides of the mounting cavity 418 in the first direction, and each air inlet channel 4145 is correspondingly communicated with an air inlet hole 4132 of one air inlet portion 413. In this way, the airflows flowing out of the two intake portions 413 are converged into the mounting chamber 418 from the first direction through the two intake passages 4145, respectively. Because the atomizing surface 432 has a greater length in the second direction than in the first direction, the airflow can mix with more aerosol.

Further, the air inlet passage 4145 has a first surface 4145a and a second surface 4145b spaced apart in the third direction (i.e., the direction in which the mounting cavity 418 points toward the atomizing chamber 4141), the atomizing surface 432 is located between the first surface 4145a and the second surface 4145b, the first surface 4145a is located on the side of the atomizing surface 432 away from the atomizing chamber 4141, and the second surface 4145b is located on the side of the atomizing surface 432 close to the atomizing chamber 4141. In a preferred embodiment, the distance H2 between the second surface 4145b and the atomizing surface 432 of the heat generating body is 0.5mm-0.5mm (as shown in fig. 3), so that the air flow in the air inlet channel 4145 does not directly blow on the atomizing surface 432 to lower the temperature of the atomizing surface 432, thereby ensuring a sufficient atomizing amount of the heat generating member 43. Moreover, the air inlet channel 4145 is arranged above the atomizing surface 432 to form an air flow which drives the aerosol to directly rise in the third direction, and compared with a mode that the air flow flows spirally, the air flow flowing mode forms an air-wrapped smoke state, so that the problem of wall hanging of mixed smoke is solved, and the effect of gathering the mixed smoke is achieved.

Referring to fig. 2 and 5, in some embodiments, the first surface 4145a is gradually increased in distance from the side close to the atomizing chamber 4141 to the side far from the atomizing chamber 4141, the second surface 4145b is opposite to the plane where the atomizing surface 432 is located, the first surface 4145a is provided with a plurality of liquid reservoirs 4145c, the plurality of liquid reservoirs 4145c are arranged at intervals along the second direction, and each liquid reservoir 4145c extends along the extending direction of the first surface 4145 a. In this manner, the condensate flowing down from the atomizing surface 432 flows in the direction of inclination of the first surface 4145a and is stored in the reservoir 4145 c. It is understood that the number and shape of the liquid storage tanks 4145c are not limited, and may be set as required to meet different liquid storage requirements.

In some embodiments, the first surface 4145a defines a plurality of air guide grooves 4145d, the plurality of air guide grooves are spaced apart along the second direction, and each air guide groove 4145d extends lengthwise along the airflow flowing direction of the air inlet channel 4145. In this way, the flow direction of the air flow is further restricted by the provision of the air guide groove 4145d, and the air flow is prevented from directly blowing the atomizing surface 432 to lower the temperature of the atomizing surface 432.

As shown in fig. 2, 5 and 6, in some embodiments, the air inlet hole 4132 formed in the air inlet portion 413 is located between the first surface 4145a and the second surface 4145b, so as to prevent the condensate on the first surface 4145a from leaking out of the air inlet hole 4132. In a preferred embodiment, each air inlet 413 is opened with a plurality of air inlet holes 4132 with a smaller diameter, and since the diameter of the air inlet holes 4132 is smaller, the condensed liquid drops will not leak through the air inlet holes 4132 due to the surface tension.

In some embodiments, the air outlet ends of the air inlet holes 4132 are located on a plane of the atomizing surface 432 away from the atomizing chamber 4141, i.e., the air outlet ends of the air inlet holes 4132 are located on a plane lower than the atomizing surface 432. In a preferred embodiment, the distance between the plane of the air inlet hole 4132 and the atomizing surface 432 is 0.3mm-1.0mm, so that the air flow moves upward along the surface of the heat generating member 43, and the air flow is smoother.

In the atomizing core 40 and the aerosol-generating device, on the one hand, the condensate formed on the atomizing surface 432 of the heat generating member 43 can flow into the air inlet channel 4145 from the edge of the atomizing surface 432, so that the problem of a small amount of smoke in the aerosol-generating device can be solved. On the other hand, the mode that the liquid guide at the bottom and the liquid guide at the side direction are combined is adopted to provide aerosol generation substrate for the heating piece 43, so that the phenomenon that the heating piece 43 is dry-burned due to the rapid rise of the temperature in the heating process can be avoided, and the user experience is effectively improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
