Referring to fig. 1, embodiments of the present application provide an atomization assembly 100, the atomization assembly 100 being installed in an aerosol-generating device, the atomization assembly 100 being for absorbing and heating an aerosol-generating substrate to generate an aerosol for use by a user. The aerosol-generating substrate is a liquid including, but not limited to, materials for medical, health, and cosmetic purposes, for example, the aerosol-generating substrate is a liquid medicine, an oil (selected according to actual protection schemes).

As shown in fig. 1 to 3 or fig. 4 to 6, the atomizing assembly 100 includes a base 20, a liquid inlet pipe 40, and a heat generating module 60. The liquid inlet pipe 40 is a hollow tubular structure with two open ends, the base 20 is connected to one open end of the liquid inlet pipe 40, an atomization cavity 41 and an airflow channel 43 are formed in the liquid inlet pipe 40, the airflow channel 43 is communicated with the other open end of the atomization cavity 41 and the liquid inlet pipe 40, and a liquid inlet hole 45 communicated with the atomization cavity 41 is formed in the side wall of the liquid inlet pipe 40. In this manner, aerosol-generating substrate outside the atomizing assembly 100 can enter the atomizing chamber 41 through the liquid inlet 45, and then be absorbed by the heat-generating module 60 and heated to atomize the aerosol.

The heat generating module 60 includes a heat generating member 62 and a liquid guiding member 64. The liquid guiding member 64 is made of porous material such as cotton core, ceramic or glass, the liquid guiding member 64 has a hollow columnar structure, and liquid guiding channels 641 axially penetrating through both end surfaces of the liquid guiding member 64 are formed in the liquid guiding member 64. In some embodiments, the heat generating member 62 is received in the liquid guiding channel 641 and covers the inner wall of the liquid guiding channel 641, and the aerosol-generating substrate flowing into the atomizing chamber 41 from the liquid inlet hole 45 can penetrate the heat conducting structure from outside to inside to reach the heat generating member 62. In other embodiments, the heat generating member 62 circumferentially covers the outer sidewall of the liquid guiding member 64, and the aerosol-generating substrate can penetrate the liquid guiding member 64 from the inside to the outside to reach the heat generating member 62. In other embodiments, when the fluid-conducting member 64 is formed of a wick, the fluid-conducting channel 641 need not be formed in the fluid-conducting member 64 (as shown in FIG. 7). It is understood that the shape of the fluid-conducting member 64 is not limited thereto, and in other embodiments, the fluid-conducting member 64 may have an approximately cylindrical structure, such as an elliptic cylinder, a prism, or the like.

It should be noted that the liquid guiding member 64 in fig. 1 to 3 may be formed of a material having a low structural strength, such as a cotton core or artificial fiber, and the liquid guiding member 64 in fig. 4 to 6 may be formed of a material having a high structural strength, such as ceramic or glass.

As described in the background art, the conventional heating element 62 is a heating element formed by processing a metal plate through chemical etching, laser/mechanical engraving, stamping and the like, and compared with elements such as the spring heating wire 6161 and the like, aerosol generated by heating has obvious advantages in taste evaluation indexes such as aroma reduction degree, aroma concentration, aroma fineness and the like, so that the heating element is widely applied.

When the heat generating member 62 is used, it is necessary to wind the heat generating member from a plane into an optimal arc shape and then assemble the heat generating member 62, and the heat generating member 62 has a notch extending along the axial direction to prevent short circuit. However, at the same time, the heat generating member 62 has no continuous support structure in the circumferential direction of the major arc, which results in the defects of low structural strength, easy deformation, etc., thereby affecting the consistency of the aerosol generating device provided with the heat generating member 62, reducing the stability of the suction life and taste, and limiting the application range of the heat generating member 62.

Referring to fig. 8 and 9, in order to solve the above problem, the heating element 62 of the present application includes a heating body 61 and an intermediate supporting member 63. The heating body 61 is wound around a central axis L to form a hollow cylindrical structure, and the heating body 61 has a core heating area a circumferentially surrounding the central axis L. The intermediate support 63 passes circumferentially around the central axis L through the core heating zone a and when the heating element 62 is in the energised state, the heating body 61 is able to generate heat under the influence of electrical energy to heat the aerosol-generating substrate, the intermediate support 63 then being in the short-circuited state with no current passing therethrough. The core heating area a is a main area of the heating body 61 that generates heat after being energized.

So, the middle support piece 63 that passes the core heating area A along the circumference has effectively improved the structural strength who generates heat 62, makes the non-deformable that generates heat 62, and then has improved the aerosol generating device's that is equipped with this generate heat 62 uniformity, has improved the stability of the suction life-span and the taste of aerosol generating device, has enlarged the range of application that generates heat 62. Moreover, no current passes through the intermediate support member 63, so that no extra electric energy loss is caused, the effective electric energy supply of the core heating area is ensured, and the atomization efficiency is ensured.

Specifically, the heat generating body 61 includes a first electrical connection portion 612, a second electrical connection portion 614, and a heat generating portion 616. The second electrical connection portion 614 and the first electrical connection portion 612 are axially spaced at opposite ends of the heat generating body 61, the heat generating portion 616 is connected between the first electrical connection portion 612 and the second electrical connection portion 614, and the heat generating portion 616 forms a core heat generating region a to heat the aerosol generating substrate. The first electrical connection portion 612 and the second electrical connection portion 614 are connected to the positive electrode and the negative electrode of the power source through the lead wires 66 (shown in fig. 3), respectively, so that the heating body 61 forms a current loop.

According to the preferential route of the current path, the current flows from the first electrical connection portion 612 to the second electrical connection portion 614 through the heat generating portion 616 without passing through the intermediate support member 63, so that the intermediate support member 63 is short-circuited, wherein no current flows, and the intermediate support member 63 does not cause additional power loss while improving the structural strength of the heat generating member 62, thereby ensuring effective power supply to the core heat generating region and ensuring atomization efficiency. Further, since it is not necessary to consider the influence of the resistance of the intermediate support 63 on the circuit, the intermediate support 63 may be provided with a large width to provide a sufficient supporting force.

Further, the heat generating body 61 includes at least two heat generating portions 616, all the heat generating portions 616 are connected in parallel between the first electrical connection portion 612 and the second electrical connection portion 614, and each heat generating portion 616 forms a core heat generating region.

Specifically, all the heat generating portions 616 are sequentially arranged along the circumferential direction around the central axis, each heat generating portion 616 includes at least two heating wires 6161 and a connector 6163, all the heating wires 6161 in the same heat generating portion 616 are arranged at intervals along the axial direction, each heating wire 6161 extends along an arc-shaped track in a wavy, linear or arc-shaped manner, and all the heating wires 6161 in the same heat generating portion 616 define a heat generating region together. The connector 6163 is a sheet-shaped structure extending lengthwise along the axial direction, and the heating wires 6161 belonging to the same heating portion 616 are electrically connected through the connector.

Thus, the heating wire 6161 generates heat under the action of electric energy to heat the aerosol generating substrate, and the connecting member 6163 can play a certain supporting role while electrically connecting two adjacent heating wires 6161. The intermediate support member 63 circumferentially passes between two axially adjacent heating wires 6161 and connects the connecting members 6163 of the respective heat generating portions 616, so as to improve the structural strength of the heat generating members 62.

In some embodiments, the first electrical connection portion 612 includes a first support portion 6121 and a first connection portion 6123. The first support portion 6121 is in a ring shape surrounding the central axis, one end of the first connection portion 6123 is connected to the first support portion 6121, and the other end of the first connection portion 6123 is connected between two adjacent heat generating portions 616. The second electrical connection portion 614 includes a second support portion 6141 and a second connection portion 6143, the second support portion 6141 is in a ring structure surrounding the central axis, one end of the second connection portion 6143 is connected to the second support portion 6141, and the other end of the second connection portion 6143 is connected between two adjacent heat generation portions 616.

In this way, the first electrical connection portion 612 and the second electrical connection portion 614 can improve the structural strength of the axial end of the heat generating member 62 while performing an electrical connection function. Since the liquid guide 64 formed of a cotton core is less rigid and more easily deformed, the first and second electrical connection portions 612 and 614 are preferably used in combination with the liquid guide 64 formed of a cotton core.

Further, in order to reduce heat loss caused by the existence of the first electrical connection portion 612 and the second electrical connection portion 614, the first electrical connection portion 612 and/or the second electrical connection portion 614 are provided with the empty groove 615, so that the heat loss area is reduced while the liquid guide member 64 is effectively supported, the pulling force is balanced, and the atomization assembly 100 is prevented from deforming. Specifically, in an embodiment, the first supporting portion 6121 and the first connecting portion 6123 of the first electrical connecting portion 612, and the second supporting portion 6141 and the second connecting portion 6143 of the second electrical connecting portion 614 each have an empty slot 615 extending along the length direction.

Referring to fig. 10 and 11, in other embodiments, the first electrical connection portion 612 and/or the second electrical connection portion 614 are sheet-shaped, and the first electrical connection portion 612 and/or the second electrical connection portion 614 are connected between two adjacent heat generating portions 616. The first electrical connection portion 612 and the second electrical connection portion 614 of the above embodiment have small areas and cannot improve effective supporting force, and therefore, are used in combination with the liquid guide 64 formed of a material such as ceramic or glass and having high structural strength. Since the first electrical connection portion 612 and the second electrical connection portion 614 have small areas, the thermal loss area can be reduced to the maximum extent while the electrical connection requirement is achieved, thereby improving the atomization efficiency and the aerosol generation amount.
