The pins 111 and the fixing seat 13 can be insulated to prevent the fixing seat 13 from being electrically connected to the pins 111, causing the heating element 11 to short-circuit, and effectively ensuring the atomization function of the atomization assembly 10.

[0040] In some embodiments, the atomizer assembly 10 further includes a seal, which fills a gap between the pin 111 and the corresponding fixing hole 1321 .

[0041] It can be understood that by filling the sealant in the gap formed between the outer periphery of the pin 111 and the inner wall 121 of the fixing hole 1321, the pin 111 and the fixing hole 1321 can be effectively fixed, thereby improving the connection reliability between the fixing hole 1321 and the pin 111, and preventing the portion of the heating element 11 installed on the fixing seat 13 from being pulled and deformed during the welding process between the pin 111 and the control circuit board, thereby avoiding damage to the atomization assembly 10, and helping to improve the yield of the atomization assembly 10; at the same time, the sealant seals the gap, thereby preventing the liquid aerosol generating matrix from leaking through the fixing hole 1321, and avoiding air leakage, thereby ensuring the normal use of the aerosol generating device.

[0047] It can be understood that using insulating materials such as plastic, ceramic or glass to make the fixing base 13 can effectively prevent the fixing base 13 from being electrically connected to the pin 111 and causing the heating element 11 to short-circuit, effectively ensuring the atomization function of the atomization component 10, and at the same time, can effectively reduce the amount of materials.

[0049] It can be understood that a stepped hole 133 is provided on the fixing seat 13 along its own axial direction, and the stepped hole 133 includes a first hole portion 1331 and a second hole portion 1332. The first hole portion 1331 is located in the fixing tube 131, and the second hole portion 1332 is located in the substrate 132. The aperture of the second hole portion 1332 is smaller than the aperture of the first hole portion 1331, so that a stepped surface is formed at the connecting position of the first hole portion 1331 and the second hole portion 1332, and the fixing hole 1321 is located on the stepped surface; due to the aperture difference formed between the first hole portion 1331 and the second hole portion 1332, the stepped surface between the first hole portion 1331 and the second hole portion 1332 has a limiting effect on the heating element 11 and the liquid guiding element 12, preventing the heating element 11 and the liquid guiding element 12 from falling out from the bottom end of the stepped hole 133, thereby ensuring the reliability of fixing the heating element 11 and the heat-conducting element in the stepped hole 133. The stepped hole 133 also has a ventilation function. The airflow enters the first hole portion 1331 from the bottom end of the second hole portion 1332, and the aerosol generated by heating and atomization of the heating element 11 flows out from the top end of the first hole portion 1331, ensuring that the atomization function of the atomization component 10 is smooth.

[0050] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 7 In some embodiments, the substrate 132 includes a main body 1322 and a barrel 1323; the outer periphery of the main body 1322 is integrally connected to the inner surface of the fixed barrel 131, and the fixing hole 1321 is located in the main body 1322; the barrel 1323 is surrounded to form the second hole portion 1332, and the barrel 1323 protrudes from the bottom surface of the main body 1322; the outer periphery of the barrel 1323 and the inner surface of the fixed barrel 131 form an annular groove 134, the fixing hole 1321 is connected to the annular groove 134, and the pin 111 is passed through the annular groove 134; the barrel 1323 is used to connect the airflow duct of the aerosol generating device.

[0051] It can be understood that the barrel 1323 is cylindrical and surrounds the second hole 1332, which is used to connect the airflow duct of the aerosol generating device to allow airflow to flow through, so that the aerosol generated by atomization in the fixed barrel 131 can flow out smoothly, thereby ensuring the atomization function of the atomization assembly 10; the outer periphery of the main body 1322 is integrally connected to the inner surface of the fixed barrel 131, and the barrel 1323 is fixed in the fixed barrel 131 through the main body 1322; the barrel 1323 protrudes from the bottom surface of the main body 1322, and the outer periphery of the barrel 1323 is connected to the inner surface of the fixed barrel 131 The interval arrangement allows the outer periphery of the barrel 1323, the main body 1322, and the inner surface of the fixed barrel 131 to jointly form an annular groove 134, and the annular groove 134 is connected to the fixing hole 1321, so that the pin 111 passes through the fixing hole 1321 and the annular groove 134; by providing the barrel 1323 and the annular groove 134 between the barrel 1323 and the fixed barrel 131, the air intake part of the atomizer assembly 10 is separated from the part where the pin 111 passes through, avoiding interference of the pin 111 with the air flow channel, and also facilitating the installation of the pin 111.

[0052] Please continue reading Figure 7 In some embodiments, a limiting groove 135 is opened on the outer periphery of the barrel 1323, the groove wall of the limiting groove 135 is connected to the inner wall 121 of the fixing hole 1321, the limiting groove 135 extends along the axial direction of the fixing hole 1321 and passes through the bottom surface of the barrel 1323; the pin 111 is located in the limiting groove 135.

[0053] It can be understood that a limiting groove 135 is provided on the outer periphery of the barrel 1323, that is, the limiting groove 135 is recessed on the outer periphery of the barrel 1323; the limiting groove 135 extends along the axial direction of the fixing hole 1321 and passes through the bottom surface of the barrel 1323, and the limiting groove 135 has a limiting effect on the pin 111. After the bottom end of the pin 111 protrudes out of the fixing hole 1321, it extends into the limiting groove 135, and the two side walls of the limiting groove 135 limit the pin 111, thereby increasing the fixing effect on the pin 111, preventing the part of the heating element 11 installed on the fixing seat 13 from being pulled and deformed during the welding process of the pin 111 and the control circuit board, thereby avoiding damage to the atomizer assembly 10, which is beneficial to improving the yield of the atomizer assembly 10. The groove wall of the limiting groove 135 is connected to the inner wall 121 of the fixing hole 1321 , so that the pin 111 protrudes from the bottom end of the fixing hole 1321 and directly extends into the limiting groove 135 , which helps to reduce the difficulty of assembling the atomizer assembly 10 .

[0054] Please continue to refer to Figure 1 , Figure 3 and Figure 4In some embodiments, a mounting notch 136 is provided on the outer periphery of the fixing seat 13, and the mounting notch 136 extends downward along the top surface of the fixing seat 13 and is connected to the first hole portion 1331; a mounting protrusion 123 extending radially is formed on the outer periphery of the liquid guiding member 12, and the mounting protrusion 123 is clamped in the mounting notch 136.

[0055] It can be understood that the mounting notch 136 is located at the periphery of the fixing seat 13, connecting the first hole portion 1331 and the outside of the fixing seat 13, so that the mounting protrusion 123 extending from the periphery of the liquid guide member 12 extends from the mounting notch 136; the mounting notch 136 extends downward along the top surface of the fixing seat 13, so that when the liquid guide member 12 is installed downward from the top of the stepped hole 133, the mounting protrusion 123 is directly installed from the mounting notch 136; the mounting protrusion 123 is clamped in the mounting notch 136, which is conducive to improving the connection reliability between the fixing seat 13 and the liquid guide member 12, and can prevent the liquid guide member 12 from twisting in the first hole portion 1331, thereby helping to improve the structural stability of the atomization assembly 10 during continuous use; the liquid guide member 12 can be made by winding a cotton strip with liquid guiding properties, and the two ends of the cotton strip are in contact at the mounting protrusion 123, that is, a contact surface is formed in the middle of the mounting protrusion 123; at this time, the mounting notch 136 can ensure that the liquid guide member 12 is fully fitted with the heating element 11.

[0056] Please continue to refer to Figure 3 and Figure 8 In some embodiments, the heating element 11 includes at least three pins 111 and a plurality of heating meshes 112. The plurality of heating meshes 112 are arranged at intervals, and the two ends of the heating mesh 112 are respectively connected to two of the pins 111, and one end of all the heating meshes 112 shares the same pin 111.

[0057] It can be understood that the heating mesh 112 can be made by stamping; using multiple heating meshes 112 is conducive to improving space utilization, increasing the heating area, and thus improving the atomization efficiency of the atomizer assembly 10; multiple heating meshes 112 are arranged at intervals, and the two ends of the heating mesh 112 are respectively connected to two pins 111, and one end of all the heating meshes 112 shares the same pin 111, that is, multiple heating meshes 112 can form multiple parallel heating circuits after being electrically connected to the control circuit board through the pin 111. By controlling the number of energized heating circuits, the heating power can be adjusted, so that the heating element 11 can be suitable for multiple heating power adjustment, thereby increasing the taste debugging space of the atomizer assembly 10, which is conducive to improving the user experience. The length of a pin 111 connected to all the heating meshes 112 protruding from the bottom end of the fixing seat 13 is the largest, which is convenient for distinguishing during the welding process.
