Only one atomizer core 1 can meet the different usage requirements of users, meet the user's demand for a large TPM, realize a plurality of different atomization tastes, and enhance the user experience.

[0042] Specifically, the substrate 11 is a porous structure, and the substrate 11 has a plurality of micropores. The substrate 11 can be a porous structure formed by porous ceramics, porous glass or other porous materials, or a porous structure formed by opening holes in a dense material. The micropores in the substrate 11 can be disordered pores, or can be specially opened ordered pores, such as array pores. The substrate 11 has the functions of conducting and storing liquid. The atomizer core 1 is applied to the electronic atomization device 300 (see below).

[0043] In some embodiments, the heating element 12 includes four electrical contacts and three sections of heating circuits, the four electrical contacts are respectively a first electrical contact 121, a second electrical contact 122, a third electrical contact 123 and a fourth electrical contact 124, and the three sections of heating circuits include a first heating circuit 125 connected between the first electrical contact 121 and the second electrical contact 122, a second heating circuit 126 connected between the second electrical contact 122 and the third electrical contact 123, and a third heating circuit 127 connected between the third electrical contact 123 and the fourth electrical contact 124. In some embodiments, the length of each section of the heating circuit is 10-15 mm, and when the electrical contacts at both ends of the heating circuit are electrically connected to the power supply assembly 200, it can be ensured that each section of the heating circuit has good heating efficiency in the power-on state, thereby ensuring the atomization performance of the atomizer core 1.

[0044] See also Figure 1 In a specific embodiment, the base 11 is a cuboid, the first surface 111 is a rectangular plane, the four electrical contacts are respectively arranged corresponding to the four vertices of the rectangular plane, the first heating line 125 and the third heating line 127 are extended in a winding direction along the length direction of the rectangular plane, the second heating line 126 is extended in a winding direction along the width direction of the rectangular plane, and along the width direction of the rectangular plane, the first heating line 125, the second heating line 126 and the third heating line 127 are arranged at intervals, and the second heating line 126 is located between the first heating line 125 and the third heating line 127.

[0045] In some embodiments, two adjacent electrical contacts among the at least four electrical contacts of the heating element 12 of the atomizer core 1 are used to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201 of the power supply assembly 200, so that a heating circuit section between the two adjacent electrical contacts can generate heat when powered on. That is to say, among the multiple electrical contacts of the heating element 12, only two electrical contacts are used to electrically correspond to the battery 201 of the power supply assembly 200, and the two electrical contacts electrically connected to the battery 201 are arranged adjacent to each other, so that among the multiple heating circuit sections, only the heating circuit section located between the two electrical contacts can generate heat when powered on, and the remaining heating circuit sections do not generate heat, which can meet the different usage requirements of users.

[0046] See also Figures 2 to 4 In some embodiments, only two of the four electrical contacts are used to electrically connect to the battery 201. Specifically, the two electrical contacts are used to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201, wherein the polarities of the first electrode 202 and the second electrode 203 are opposite, the first electrode 202 can be the positive electrode of the battery 201 of the power supply component 200, and the second electrode 203 can be the negative electrode of the battery 201, or the first electrode 202 can also be the negative electrode of the battery 201 of the power supply component 200, and the second electrode 203 can be the positive electrode of the battery 201.

[0047] like Figure 2As shown, in a specific embodiment, the first electrical contact 121 of the heating element 12 is used to be electrically connected to the first electrode 202 of the battery 201 of the power supply component 200, and the second electrical contact 122 is used to be electrically connected to the second electrode 203 of the battery 201 of the power supply component 200, so that the first heating circuit 125 connected between the first electrical contact 121 and the second electrical contact 122 can generate heat when powered on to heat the aerosol generating matrix in the atomization substrate 11.

[0048] like Figure 3 As shown, in another specific embodiment, the second electrical contact 122 of the heating element 12 is used to be electrically connected to the first electrode 202 of the battery 201 of the power supply component 200, and the third electrical contact 123 is used to be electrically connected to the second electrode 203 of the battery 201 of the power supply component 200, so that the second heating circuit 126 connected between the second electrical contact 122 and the third electrical contact 123 can generate heat when powered on to heat the aerosol generating matrix in the atomization substrate 11.

[0049] like Figure 4 As shown, in another specific embodiment, the third electrical contact 123 of the heating element 12 is used to electrically connect to the first electrode 202 of the battery 201 of the power assembly 200, and the fourth electrical contact 124 is used to electrically connect to the second electrode 203 of the battery 201 of the power assembly 200, so that the third heating circuit 127 connected between the third electrical contact 123 and the fourth electrical contact 124 can generate heat in the energized state to heat the aerosol-generating matrix in the atomizing substrate 11. In this embodiment, the first electrode 202 is a positive electrode and the second electrode 203 is a negative electrode. In other embodiments, the first electrode 202 can be a negative electrode and the second electrode 203 can be a positive electrode.

[0050] Through the above-mentioned several different electrical connection methods between the heating element 12 and the first electrode 202 and the second electrode 203 of the battery 201, the atomizer core 1 has more diverse temperature field distributions, can achieve a variety of different atomization effects, meet more user needs, and can meet different suction taste requirements, so that the atomizer core 1 has a wider application range.

[0051] In other embodiments, the number of electrical contacts of the heating element 12 can also be set to five, six, seven or other arbitrary numbers, and the heating element 12 can also correspond to four, five, six or other arbitrary numbers of heating circuits, and a heating circuit is connected between two adjacent electrical contacts. Among the multiple electrical contacts, two other adjacent electrical contacts can also be electrically connected to the first electrode 202 and the second electrode 203 of the battery 201. For example, the fifth electrical contact can be used to electrically connect to the first electrode 202 of the battery 201, and the sixth electrical contact can be used to electrically connect to the second electrode 203 of the battery 201, so that the fifth heating circuit connected between the fifth electrical contact and the sixth electrical contact generates heat when powered on, so as to achieve more electrical connection methods and meet more usage requirements. The number of electrical contacts and heating circuits of the heating element 12 can be designed as needed, and this application does not limit this.

[0052] See also Figures 5 and 6 , Figure 5 yes Figure 1 The schematic diagram of the structure of the fourth electrical connection method of the atomizer core provided, Figure 6 yes Figure 1 A schematic structural diagram of a fifth electrical connection method of the atomizer core is provided.

[0053] See also Figure 5 and Figure 6 In some embodiments, among the multiple electrical contacts of the heating element 12, two non-adjacent electrical contacts are used to electrically connect with the first electrode 202 and the second electrode 203 of the battery 201 of the power supply assembly 200. Specifically, two sections of heating circuits and one electrical contact are connected between the two electrical contacts electrically connected with the first electrode 202 and the second electrode 203, so that when the two non-adjacent electrical contacts of the heating element 12 are electrically connected with the battery 201, the two adjacent sections of the heating circuits between the two electrical contacts can generate heat in the power-on state to heat the atomized aerosol to generate the matrix. It can be understood that using two non-adjacent electrical contacts to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201 can increase the number of heating circuits that generate heat in the power-on state, which is conducive to improving the heating efficiency, increasing the heating area of ​​the heating element 12, improving the atomization efficiency, and helping to increase the aerosol release amount, improve TPM, and meet the demand for a larger TPM.

[0054] like Figure 5As shown, in a specific embodiment, the first electrical contact 121 and the third electrical contact 123 of the four electrical contacts are used to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201 of the power supply component 200, wherein the first electrical contact 121 can be electrically connected to the first electrode 202, and the third electrical contact 123 can be electrically connected to the second electrode 203, so that the first heating circuit 125 and the second heating circuit 126 connected between the first electrical contact 121 and the third electrical contact 123 can generate heat when powered on, wherein the first heating circuit 125 and the second heating circuit 126 are connected in series with each other.

[0055] like Figure 6 As shown, in another specific embodiment, the second electrical contact 122 and the fourth electrical contact 124 of the four electrical contacts are used to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201 of the power supply assembly 200, so that the second heating circuit 126 and the third heating circuit 127 connected between the second electrical contact 122 and the fourth electrical contact 124 can generate heat in the power-on state, wherein the second heating circuit 126 and the third heating circuit 127 are connected in series with each other. In this embodiment, the first electrode 202 is a positive electrode and the second electrode 203 is a negative electrode. In other embodiments, the first electrode 202 can be a negative electrode and the second electrode 203 can be a positive electrode. Different temperature field distributions can be achieved through different electrical connection methods to meet different usage requirements.

[0056] Similarly, in other embodiments, the number of electrical contacts of the heating element 12 can also be set to five, six, seven, eight or other arbitrary numbers, and the heating element 12 can also correspond to four, five, six, seven or other arbitrary numbers of heating circuits, and a heating circuit is connected between two adjacent electrical contacts, and the two non-adjacent electrical contacts for electrically connecting to the first electrode 202 and the second electrode 203 of the battery 201 can also be other electrical contacts. For example, the fourth electrical contact 124 can be used to electrically connect to the first electrode 202 of the battery 201, and the sixth electrical contact can be used to electrically connect to the second electrode 203 of the battery 201, so that the fourth heating circuit and the fifth heating circuit connected between the fourth electrical contact 124 and the sixth electrical contact can generate heat when powered on. The specific number of electrical contacts and the arrangement of the electrical contacts for electrically connecting to the first electrode 202 and the second electrode 203 of the battery 201 can be designed as needed, as long as the two sections of the heating circuit between the two electrical contacts can generate heat when powered on, and this application does not limit this.

[0057] See also Figure 7 , Figure 7 yes Figure 1 A schematic structural diagram of a sixth electrical connection method of the atomizer core is provided.

[0058] See also Figure 7 In some embodiments, only two of the multiple electrical contacts are used to electrically connect to the first electrode 202 and the second electrode 203 of the battery 201, and three sections of heating circuits and two electrical contacts are connected between the two electrical contacts electrically connected to the first electrode 202 and the second electrode 203, so that the three sections of heating circuits connected between the two electrical contacts can generate heat in the power-on state to heat the aerosol-generating matrix in the substrate 11 and generate aerosol. Through the above-mentioned electrical connection method, the three sections of the heating circuit of the heating element 12 can generate heat in the power-on state, further increasing the heating area of ​​the heating element 12, which is more conducive to improving the heating efficiency, thereby improving the atomization efficiency of the atomizer core 1, meeting a larger TPM requirement, and helping to solve the problem that the atomizer core 1 in the prior art is difficult to meet a larger TPM requirement.

[0059] like Figure 7 As shown, in a specific embodiment, the heating element 12 includes four electrical contacts and three heating circuits, wherein the first electrical contact 121 is used to electrically connect to the first electrode 202 of the battery 201 of the power supply component 200, and the fourth electrical contact 124 is used to electrically connect to the second electrode 203 of the battery 201 of the power supply component 200, so that the three heating circuits of the first heating circuit 125, the second heating circuit 126 and the third heating circuit 127 can all generate heat when powered on, and the three heating circuits are connected in series to meet greater TPM requirements and more puffing tastes.

[0060] It can be understood that in the above-mentioned multiple embodiments, a variety of different electrical connection methods between the heating element 12 and the first electrode 202 and the second electrode 203 of the battery 201 can achieve different atomization effects. The electrical contacts at both ends of any heating circuit, or the electrical contacts at both ends of two adjacent heating circuits, or the electrical contacts at both ends of three adjacent heating circuits are used to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201, and different powers can be output to different sections of the heating circuits, so that the multiple sections of the heating circuits of the heating element 12 have different heating powers, and the atomizer core 1 can have different temperature field distributions, so as to achieve more atomization tastes and meet more usage requirements.

[0061] In other embodiments, the number of electrical contacts of the heating element 12 may also be set to five, six, seven, eight or any other number, and the heating element 12 may also include four, five, six, seven or any other number of heating circuits, and a heating circuit is connected between two adjacent electrical contacts. The two electrical contacts for electrically connecting to the first electrode 202 and the second electrode 203 may also be other electrical contacts, and three heating circuits may be connected between the two electrical contacts, or four, five or other number of heating circuits may be connected.

[0062] For example, the second electrical contact 122 and the fifth electrical contact can be used to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201, so that the second heating circuit 126, the third heating circuit 127 and the third heating circuit 127 connected between the second electrical contact 122 and the fifth electrical contact can generate heat when powered on; or, the first electrical contact 121 and the fifth electrical contact can be directly used to electrically correspond to the first electrode 202 and the second electrode 203 of the battery 201, so that the first electrical contact 121 and the fifth electrical contact can be connected to the first electrical contact 122 and the fifth electrical contact. The four heating circuits of the first heating circuit 125, the second heating circuit 126, the third heating circuit 127 and the third heating circuit 127 between the first and fifth electrical contacts 121 can generate heat when powered on, or the first electrical contact 121 and the last electrical contact can be used to electrically connect to the first electrode 202 and the second electrode 203 of the battery 201, so that the multiple heating circuits of the heating element 12 can generate heat when powered on, further improving the heating efficiency of the heating element 12, improving the atomization efficiency, and meeting greater TPM requirements. The specific number of electrical contacts and heating circuits and the location of the electrical contacts electrically connected to the first electrode 202 and the second electrode 203 of the battery 201 can be designed as needed, and this application does not limit this.

[0063] In some embodiments, the resistance of the first heating circuit 125 and the third heating circuit 127 is greater than the resistance of the second heating circuit 126, so that when the first heating circuit 125, the second heating circuit 126 and the third heating circuit 127 are heated in the power-on state, the heating efficiency of the first heating circuit 125 and the third heating circuit 127 is greater than the heating efficiency of the second heating circuit 126. In some embodiments, the resistance of the first heating circuit 125 and the third heating circuit 127 is substantially the same, that is, when the first heating circuit 125 and the third heating circuit 127 are heated in the power-on state, the heating efficiency is substantially the same. Through the electrical connection of different electrical contacts to the power supply assembly 200, different heating circuits have different heating efficiencies, thereby enabling the atomizer core 1 to achieve different atomization powers, and the atomizer 100 has a variety of different temperature field distributions to meet more diverse atomization requirements.

[0064] In other embodiments, the resistance of the first heating circuit 125 and the third heating circuit 127 may be substantially the same as the resistance of the second heating circuit 126, or the resistance of the first heating circuit 125 and the third heating circuit 127 may be smaller than the resistance of the second heating circuit 126, or the resistance of the first heating circuit 125 and the third heating circuit 127 may be different, which can be designed as needed.

[0065] See also Figure 8 , Figure 8 yes Figure 1 A schematic diagram of the structure of the seventh electrical connection method of the atomizer core is provided.

[0078] The electronic atomization device 300 also includes other components such as a conductive member 5 and an airflow sensor 204. The conductive member 5 is mounted on the second mounting seat 34, one end of the conductive member 5 abuts against the electrical contact of the heating element 12 of the atomization core 1, and the other end is electrically connected to the battery 201 of the power supply assembly 200, so that the electrical contact of the atomization core 1 can be electrically connected to the first electrode 202 and the second electrode 203 of the battery 201 through the conductive member 5.
