[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] ​​Firstly, the heating element of the atomization assembly in the prior art is described. The heating element in the prior art is generally integrally formed and processed into a sheet or ring structure. Two pins are generally provided to connect the positive and negative poles of the power supply to heat the whole body. However, the whole heating mode will cause uneven temperature heating due to the material, shape or structure of the heating element body, the connection position of the pins and other reasons, thereby causing a large temperature gradient, affecting the taste of the atomization device in use, and increasing the risk of the atomization device paste core. At the same time, the heating element is prone to deformation when heated due to the thin structure, for example, as shown in Figure 10 , the heating element expands and deforms severely after being heated, and the deformation state is uncontrollable, that is, the heating element is deformed from the B structure in the figure to the D structure. At this time, it further increases the risk of the atomization device paste core. To this end, the present application provides an atomization assembly and an atomization device for solving the above problems. Some embodiments are described below.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , one embodiment of the present application provides an atomization assembly, comprising:

[0038] a support 10, the inner side of the support 10 forms an air channel 100, and the support 10 is provided with a liquid inlet 101;

[0039] a liquid guide 20, the liquid guide 20 is arranged in the air channel 100, and at least part of the liquid guide 20 covers the liquid inlet 101;

[0040] a heating element 30, the heating element 30 is arranged on the inner side of the liquid guide 20; the heating element 30 is provided with at least three pins 300, the pins 300 are connected with a control circuit, and a heating part is defined between every two pins 300.

[0041] The support 10 is a support structure of the atomization assembly, which can provide a space to form the air channel 100 and can install the whole atomization assembly in the atomization device, so that the atomization assembly can cooperate with the air channel in the atomization device. In this embodiment, the air channel 100 formed by the support 10 is in communication with the air channel formed by the atomization device. Specifically, the air channel 100 formed by the support 10 is provided with a liquid inlet 101, one end of the liquid inlet 101 is connected with the liquid guide 20, and the other end of the liquid inlet 101 is in communication with the liquid storage cavity of the atomization device, so that the atomization substrate in the liquid storage cavity can enter the atomization assembly through the liquid inlet 101 to be atomized. In one example, the liquid inlet 101 is a liquid inlet hole.

[0042] The liquid guide 20 is used to guide the atomized substrate entering the liquid inlet 101 to the heating element 30 for heating. Specifically, the liquid guide 20 is connected with the liquid inlet 101, and there are various connection modes. One is that one side of the liquid guide 20 is closely attached to the liquid inlet 101, so that the atomized substrate in the liquid inlet 101 can enter the liquid guide 20. The other is that one end of the liquid guide 20 extends into the interior of the liquid inlet 101 and fills the liquid inlet 101, which can also enable the atomized substrate in the liquid inlet 101 to enter the liquid guide 20. It should be noted that the liquid guide 20 in the present application only needs to partially cover or partially extend into the liquid inlet 101 to contact the atomized substrate to achieve the liquid guiding effect.

[0043] The heating element 30 is an important structure of the atomization assembly and is attached to one side of the liquid guide 20. Specifically, the heating element 30 is provided with at least three pins 300, which are connected with the control circuit to serve as access points of the circuit, and then the different pins 300 are controlled individually by the control circuit, that is, the connection of any two pins 300 is controlled to define the heating part between the two controlled pins 300, thereby realizing the function of partition temperature control. This arrangement can improve the versatility of the atomization assembly or the atomization core, adapt to more atomization schemes, improve the atomization efficiency, reduce battery consumption, and be suitable for various electronic control schemes. In addition, the multiple pins 300 can also support the heating element 30, and the multiple pins 300 can serve as the support framework of the heating element 30, so that the heating element 30 is not easy to deform and the deformation resistance of the heating element 30 is improved. For the connection of the pins 300 with the control circuit, the way of defining the heating part between two pins 300 to realize the partition temperature control, and the formation of the heating part, please refer to the description in the following embodiments.

[0044] The way of partition temperature control in this embodiment will be described below. For example, please refer to Figure 9 In this embodiment, five pins 300 are equally and spacedly arranged on the heating element 30, which are named as pin A, pin B, pin C, pin D and pin E. The heating element 30 is divided into multiple heating parts (or heating areas) by this arrangement, including heating parts AB, BC, CD and DE, and heating parts AC, BD and CE. That is, any two pins 300 can form a heating part, that is, two pins 300 define a heating part, which can be adjacent two pins 300 or non-adjacent two pins 300.

[0045] In this embodiment, by changing the connection position of the positive and negative electrodes, the heating of the heating part defined by different pins 300 of the heating element 30 can be controlled to realize the function of partition temperature control.

[0046] For example, the positive and negative electrodes are set to AB, BC and CD by the control circuit, and at this time, the single-network heating mode is implemented. The meaning of the positive and negative electrodes "AB" is that pin A is connected to the positive electrode and pin B is connected to the negative electrode, or pin B is connected to the positive electrode and pin A is connected to the negative electrode, and the meaning of the other positive and negative electrodes is the same as above, which will not be repeated here.

[0047] For another example, the positive and negative electrodes are set to AC, BD and CE by the control circuit, and at this time, the double-network heating mode is implemented.

[0048] For yet another example, the positive and negative electrodes are AD, BE and AE, and at this time, the multi-network heating mode is implemented.

[0049] For still another example, the positive and negative electrodes are connected to the pins 300 by the control circuit, and the power supply can also be set to double positive and double negative, for example, AB and DE are connected at the same time, and the mode of heating at both ends and not heating in the middle can be implemented.

[0050] It should be noted that, in addition to this, the input of the power supply of the control circuit can be a fixed value or a function that changes over time, and the heating element 30 can match multiple circuit control schemes.

[0051] In an embodiment, the heating element 30 is tightly attached to the inner surface of the liquid guide 20, and the liquid guide 20 is tightly attached to the inner surface of the support 10. The surface of the support 10 is provided with a liquid inlet 101, and the position of the liquid inlet 101 is directly opposite to the defined heating part of the heating element 30. This arrangement enables the atomized substrate in the liquid inlet 101 to reach the heating element 30 to be heated and atomized more quickly.

[0052] In an embodiment, please refer to Figure 9 The pins 300 are arranged at intervals on one side of the heating element 30, and the distance between adjacent pins 300 is equal. This makes the effect of partition temperature control more uniform.

[0053] It should be noted that in actual use, the number of pins 300 can be adjusted according to the size of the heating element 30. In an embodiment, the number of pins 300 can also be set to 2, and at this time, the effect of partition temperature control cannot be achieved.

[0054] It should be noted that the "atomized substrate", "liquid", "aerosol substrate" and the like expressed in this application are tobacco tar in an embodiment.

[0055] In an embodiment, please refer to Figure 1The support 10 is provided with a limiting groove 102, and one end of the liquid guide 20 extends into the limiting groove 102. The limiting groove 102 is provided to limit the liquid guide 20 and fix the liquid guide 20 on the support 10. Specifically, one end of the liquid guide 20 extends into the limiting groove 102 and is fixed by the limiting groove 102, and the other end abuts against the inner wall of the support 10 or extends into the liquid inlet 101 of the support 10 (not shown in the figure). The liquid guide 20 contacts the liquid inlet 101 in the air duct 100, and the heating element 30 is arranged on the side surface of the liquid guide 20. Figure 5

[0056] It should be noted that the shape of the liquid guide 20 is not limited in the present application, as long as the liquid guide 20 is located in the air duct 100 and is in contact with the heating element 30.

[0057] In one embodiment, referring to Figure 2 The liquid guide 20 has a ring structure, and the outer wall of the liquid guide 20 is arranged in contact with the inner wall of the air duct 100. It can be understood that, in one embodiment, the inner wall of the air duct 100 refers to the inner wall of the support 10. The two ends of the liquid guide 20 extend along the inner wall of the air duct 100 and extend into the limiting groove 102. This arrangement can maximize the contact area or the number of contacts between the liquid guide 20 and the liquid inlet 101 on the air duct 100, thereby improving the atomization efficiency.

[0058] In one embodiment, referring to Figure 2 The liquid guide 20 has a ring structure, and the outer wall of the liquid guide 20 is arranged in contact with the inner wall of the air duct 100. The heating element 30 is arranged in contact with part of the inner wall of the liquid guide 20. This arrangement can further increase the contact area between the liquid guide 20 and the heating element, thereby improving the atomization efficiency. It should be noted that the heating element 30 is arranged in contact with the inner wall of the liquid guide 20, and the heating element 30 can extend along the inner wall of the liquid guide 20, but the two ends of the heating element 30 should not be in contact, otherwise a short circuit will occur.

[0059] In one embodiment, the pin 300 is connected to the heating element 30 by welding.

[0060] In one embodiment, referring to Figure 2 , Figure 6 and Figure 7 The atomization assembly further comprises a fixing member 40 made of an insulating material.

[0061] ​The middle part of the pin 300 is fixed on the heating element 30, one end of the pin 300 extends to the side away from the heating element 30 and is connected with the control circuit, and the other end of the pin 300 extends to the side away from the heating element 30, and the fixing element 40 presses the other end of the pin 300 towards the inner wall of the liquid guide 20, so that the other end of the pin 300 is fixed on the inner wall of the liquid guide 20 through the fixing element 40.

[0062] In the case where the pin 300 is connected with the heating element 30, generally, one end of the pin 300 is connected with the access end of the control circuit in the direction away from the heating element 30. The other end is maintained within the size range of the heating element 30 and does not protrude from the heating element 30. In this arrangement, only one end of the pin 300 is constrained, and the other end is not constrained, so that the unconstrained end is easily deformed by thermal expansion during heating, thereby affecting the stability of the heating element 30. Therefore, in the arrangement of the present embodiment, the unconstrained end of the pin 300 is extended away from one end of the heating element 30, and then it is fixed on the liquid guide 20 through the fixing element 40, so that the thermal deformation of the pin 300 is avoided, thereby improving the stability of the heating element 30.

In this embodiment, the pin 300 is clamped between the fixing element 40 and the liquid guide 20 through the ring structure of the fixing element 40, so as to fix the other end of the pin 300. The outer diameter of the fixing element 40 is greater than or equal to the distance from the surface of the pin 300 to the center of the airway 100, which is the basis for fixing the pin 300 by the fixing element 40. However, in the case where the outer diameter of the fixing element 40 is greater than the distance from the surface of the pin 300 to the center of the airway 100, it is considered that the liquid guide 20 may be made of flexible material and has elasticity, so that the pin 300 can be further fixed by the fixing element 40.

[0064] In one embodiment, please refer to Figure 8 The fixing element 40 is provided with a groove 400 corresponding to one side of the pin 300, and part of the pin 300 is embedded in the groove 400. The groove 400 is arranged to limit the pin 300 and prevent the pin 300 from sliding along the circumference of the fixing element 40, thereby improving the stability of the fixing of the pin 300.

[0065] In one embodiment, please refer to Figure 7The fixing member 40 is provided with a limiting member 401, one end of the limiting member 401 is connected with the fixing member 40, and the other end of the limiting member 401 is clamped on the supporting member 10. The limiting member 401 is provided to ensure that the limiting member 401 can be fixed in the airway 100 and not slide along the inner wall of the liquid guide 20.

This arrangement can improve the liquid guiding efficiency of the liquid guide 20 and ensure that the atomized matrix in the liquid inlet 101 can accurately and quickly reach the heating part.
