[0041] Example 1

[0042] Combine Figures 1 to 4, the present application provides an atomizer assembly 10. The atomizer assembly 10 includes an atomizer housing 100, an atomizer base 200, an atomizer core 300 and an atomizer electrode 400. The atomizer housing 100 has a liquid storage chamber 101 and an air outlet channel 102. The atomizer base 200 is installed on the atomizer housing 100, and the atomizer base 200 and the inner wall of the atomizer housing 100 enclose an atomizer chamber 201. The atomizer chamber 201 is respectively connected to the liquid storage chamber 101 and the air outlet channel 102. The atomizer base 200 has a first electrode through hole 202 connected to the atomizer chamber 201. The atomizer core 300 is installed in the atomizer chamber 201 and includes a first liquid guide 310 and a heating element 320. The first liquid guide 310 is connected to the liquid storage chamber 101 and the air outlet channel 102 respectively. The heating element 320 is sleeved on the first liquid guide 310, and the heating element 320 seals and separates the first electrode through-hole 202 and the atomizer chamber 201. The atomizer electrode 400 is inserted into the first electrode through-hole 202, and the end of the atomizer electrode 400 abuts the heating element 320.

[0043] If the heating element 320 is connected to the atomizing electrode 400 by welding the pins, and the pins are then passed through the atomizing base 200 and welded to the atomizing electrode 400, then there is a risk of poor welding or solder joint failure between the pins and the heating element 320 and between the pins and the atomizing electrode 400; secondly, the atomizing base 200 needs to have pin holes for the pins to pass through, which will cause the atomizing chamber 201 to be connected to the outside through the pin holes, increasing the risk of leakage of the atomized liquid; thirdly, the welding of the pins and the bending and passing of the pins will also increase the assembly cost and reduce the assembly efficiency.

[0044] In the present application, the atomizing electrode 400 is installed from the outside of the atomizing housing 100 into the first electrode through hole 202 of the atomizing base 200, and abuts against the heating element 320 that seals the first electrode through hole 202, so that the atomizing electrode 400 and the heating element 320 are connected, and can supply power to the heating element 320. When the heating element 320 is powered on, it heats the sleeved first liquid guide member 310, and the atomized liquid from the liquid storage chamber 101 is heated and atomized in the first liquid guide member 310, and is mixed with the gas in the atomizing chamber 201 and leaves the atomizing assembly 10 from the air outlet channel 102. Among them, the atomizing electrode 400 and the heating element 320 are connected by abutment, and no welding operation is required. On the one hand, it reduces the risk of poor contact due to poor welding and solder joint failure, and on the other hand, it reduces the welding assembly cost, simplifies the assembly process, and improves assembly efficiency. At the same time, the heating element 320 seals and separates the first electrode through-hole 202 and the atomization chamber 201, which can prevent the gas, liquid or aerosol in the atomization chamber 201 from leaking to the outside of the atomization shell 100 through the first electrode through-hole 202, effectively avoiding leakage problems. In addition, the heating element 320 seals the first electrode through-hole 202, and the area of ​​the heating element 320 at the outlet of the first electrode through-hole 202 is larger, which facilitates the atomization electrode 400 to contact the large-area heating element 320 through the first electrode through-hole 202. The large contact area between the two ensures the conduction stability between the atomization electrode 400 and the heating element 320. In addition, the heating element 320 is sleeved on the first liquid guiding element 310. On the one hand, the bonding force between the heating element 320 and the first liquid guiding element 310 is enhanced, the position stability of the two is improved, and the heating element 320 is ensured to reliably heat the atomized liquid transported by the first liquid guiding element 310. On the other hand, the heating element 320 is sleeved on the first liquid guiding element 310, and the position of the heating element 320 is more stable, ensuring that the heating element 320 is reliably sealed to separate the first electrode through hole 202 and the atomization chamber 201, and the heating element 320 is reliably connected to the atomization electrode 400, further improving the conductive stability of the heating element 320 and the atomization electrode 400, and improving the working stability of the atomization assembly 10.

[0045] In some embodiments, the liquid storage chamber 101 is used to store an aerosol-generating substrate. The aerosol-generating substrate can be a liquid aerosol-generating substrate or a solid aerosol-generating substrate, which is not specifically limited here.

[0046] If the resistance of the heating element 320 is the same everywhere and the atomized liquid is heated to atomization everywhere, the atomized liquid will be atomized at both ends of the first liquid guide member 310, and no atomized liquid will flow through the middle of the first liquid guide member 310, resulting in the risk of the middle of the first liquid guide member 310 burning after continuous long-term use.

[0047] In some embodiments, combined Figure 2 、 Figure 5 and Figure 6The heating element 320 includes two heat-conducting sleeves 321, which are spaced apart and sleeved with the first liquid-conducting member 310. The two heat-conducting sleeves 321 are connected by a heating wire 322. When current flows through the heating element 320 along the first heat-conducting sleeve 321, the heating wire 322, and the second heat-conducting sleeve 321, the cross-sectional area of ​​the heating wire 322 is smaller than the cross-sectional area of ​​the heat-conducting sleeve 321, and the resistance of the heating wire 322 is greater than the resistance of the heat-conducting sleeve 321. The middle part of the first liquid-conducting member 310 is heated near the heating wire 322, and the atomized liquid at this position is atomized. The heat is simultaneously diffused to the two ends of the first liquid-conducting member 310 through the heat-conducting sleeve 321 and the first liquid-conducting member 310, accelerating the flow of the atomized liquid from the end of the first liquid-conducting member 310 to the middle part of the first liquid-conducting member 310, thereby reducing the risk of burning the middle part of the first liquid-conducting member 310.

[0048] Furthermore, the two heat-conducting sleeves 321 are spaced apart, ensuring uniform heating at both ends of the first liquid-conducting member 310, avoiding localized overheating and effectively reducing the risk of burns. Furthermore, the atomizer core 300 precisely controls the atomization position of the atomized liquid by controlling the position of the heating wire 322. This position can be adjusted to be closer to the air outlet channel 102, allowing the aerosol formed after atomization to promptly exit the atomization chamber 201 through the air outlet channel 102.

[0049] In one embodiment, combined Figure 3 and Figure 4 The heating wire 322 is located on the extension line of the air outlet channel 102, which is beneficial for the aerosol to enter the air outlet channel 102 over a short distance, thereby improving the smoothness of air outlet.

[0050] In one embodiment, the combination Figure 5 and Figure 6 The number of heating wires 322 is multiple, and the multiple heating wires 322 are spaced apart. The multiple heating wires 322 are connected in parallel and simultaneously, which improves the heating efficiency of the atomizer core 300, can disperse the current load, and the aerosol particles formed are finer and more evenly distributed. The multiple heating wires 322 spaced apart can more evenly heat the first liquid guide 310, reduce local overheating, and further reduce the risk of core burn. In addition, if any heating wire 322 is disconnected, the other heating wires 322 can continue to operate normally, improving the operating stability and reliability of the atomizer core 300.

[0051] In one embodiment, the combination Figure 4 、 Figure 5 and Figure 6The first liquid-guiding member 310 has a mounting side surface 311. The angle between the normal of the mounting side surface 311 and the flow direction of the air outlet channel 102 is 60° to 120°. In other words, the mounting side surface 311 does not directly face the air outlet channel 102. The heating wire 322 is arranged against the mounting side surface 311, that is, the heating wire 322 does not directly face the air outlet channel 102. The heating wire 322 does not block the flow of aerosol or other fluids toward the air outlet channel 102. The heating wire 322 is located beside the flow direction of the air outlet channel 102, so that the atomized liquid in the first liquid-guiding member 310 is gradually heated along the flow direction of the air outlet channel 102 and smoothly enters the air outlet channel 102 along the flow direction of the air outlet channel 102.

[0052] Specifically, there are two mounting sides 311, and the two mounting sides 311 are located on opposite sides of the flow direction of the air outlet channel 102. The heating wires 322 on both sides evenly heat the atomized liquid in the first liquid guide part 310 without blocking the air inflow from below or the aerosol outflow from above, so that the fluid flows smoothly.

[0053] Specifically, the mounting side surface 311 is perpendicular to the flow direction of the air outlet channel 102 , that is, the heating wire 322 does not block the flow of the fluid at all, further enabling the fluid to flow smoothly.

[0054] The mounting side surface 311 may be a plane, a curved surface, or an irregular surface, which is not specifically limited here. When the mounting side surface 311 is a non-planar surface, the direction of the mounting side surface 311 is the normal direction of the plane obtained by fitting the edge points of the mounting side surface 311.

[0055] In one embodiment, the combination Figure 3 and Figure 5 The heat-conducting sleeve 321 has a notch 323 on one side near the liquid storage chamber 101, and the first liquid guide 310 is connected to the liquid storage chamber 101 through the notch 323. The design of the notch 323 allows the atomized liquid in the liquid storage chamber 101 to flow directly to the first liquid guide 310, reducing flow resistance and ensuring that the atomized liquid in the first liquid guide 310 can be replenished in a timely manner. On the one hand, this improves atomization efficiency, and on the other hand, it reduces the risk of the first liquid guide 310 becoming sticky.

[0056] In one embodiment, the combination Figure 5 and Figure 6The heating wire 322 and two thermally conductive sleeves 321 are integrally formed. The integrally formed heating wire 322 and thermally conductive sleeves 321 enhance the integrity of the heating element 320. The heating element 320 has no internal connection gaps, eliminating connection defects and poor contact issues that may arise from separate connection methods such as welding or riveting, greatly reducing the risk of short circuits caused by poor insulation or external damage. Furthermore, the integrally formed heating element 320 has high precision, which can improve the sealing performance of the thermally conductive sleeve 321 with respect to the first electrode through-hole 202.

[0057] Specifically, the heating element 320 is integrally stretched and formed into a sleeve, and the middle portion of the sleeve is corroded to form a heating wire 322 , while both ends of the sleeve are not corroded to form a heat-conducting sleeve 321 .

[0058] In some embodiments, combined Figure 2 and Figure 3 The atomizer core 300 further includes a second liquid guide 330, which is located on a side of the first liquid guide 310 close to the liquid storage chamber 101 and covers the outlet of the liquid storage chamber 101. The second liquid guide 330 can buffer the rate at which the atomized liquid in the liquid storage chamber 101 flows toward the first liquid guide 310, ensuring uniform flow of the atomized liquid in the first liquid guide 310. This avoids local overheating or insufficient atomization caused by uneven distribution of the atomized liquid on the first liquid guide 310.

[0059] In addition, the second liquid guiding member 330 can absorb the atomized liquid to prevent the atomized liquid from leaking to other locations of the atomizing chamber 201 , thereby ensuring that the atomized liquid in the liquid storage chamber 101 flows along the second liquid guiding member 330 and the first liquid guiding member 310 .

[0060] In one embodiment, the combination Figure 2 and Figure 3 The second liquid guide 330 has a first air outlet hole 331, which is connected to the air outlet channel 102. The first air outlet hole 331 avoids the air outlet channel 102, allowing aerosol to flow smoothly and unimpeded through the first air outlet hole 331 into the air outlet channel 102, preventing blockage and condensation and improving airflow efficiency.

[0061] In one embodiment, the combination Figure 2 and Figure 3 , projected along the through-going direction of the first air outlet hole 331, the projection of the inlet of the air outlet channel 102 is located within the projection of the first air outlet hole 331. In other words, the flow cross-sectional area of ​​the first air outlet hole 331 is larger than the flow cross-sectional area of ​​the inlet of the air outlet channel 102, completely unobstructing the aerosol and enhancing the guidance of the airflow. The airflow can enter the air outlet channel 102 more directly and efficiently through the first air outlet hole 331, reducing airflow dispersion and loss.

[0062] In some embodiments, combined Figure 2 and Figure 3 The atomizing electrode 400 is in planar contact with the heating element 320. The planar contact provides a larger contact area, making the contact between the atomizing electrode 400 and the heating element 320 more stable, which helps reduce the risk of poor contact or falling off due to dimensional error, assembly error, vibration or impact.

[0063] In some embodiments, combined Figure 2 and Figure 3 There are two atomizing electrodes 400, one of which is connected to the positive pole of the power supply, and the other is connected to the negative pole of the power supply. Correspondingly, there are two first electrode through holes 202. The two atomizing electrodes 400 are in contact with both ends of the heating element 320 to form a current loop.

[0064] In some embodiments, combined Figures 2 to 4 The atomizer assembly 10 further includes a first sealing member 500, which is sealingly mounted on the atomizer chamber 201. The first sealing member 500 has a liquid outlet 501 and a second air outlet hole 502. The liquid outlet 501 connects the liquid storage chamber 101 and the atomizer chamber 201, and the second air outlet hole 502 connects the air outlet channel 102 and the atomizer chamber 201. The first sealing member 500 seals the liquid storage chamber 101 and the air outlet hole, allowing only the liquid storage chamber 101 to communicate with the atomizer chamber 201 through the liquid outlet hole, while the atomizer chamber 201 communicates with the air outlet channel 102 through the second air outlet hole 502, thereby preventing communication between the liquid storage chamber 101 and the air outlet channel 102, and effectively separating the flow path of the atomized liquid from the flow path of the aerosol.

[0065] Optionally, the first sealing member 500 is a first silicone member.

[0066] In some embodiments, combined Figures 2 to 4 The atomizer assembly 10 also includes a second seal 600, which is sealed and installed in the atomizer chamber 201, further enhancing the sealing performance of the atomizer assembly 10, preventing the atomized liquid or steam from leaking from unexpected paths, and ensuring the stability and safety of the atomization process. The second seal 600 has a second electrode through-hole 601, which connects the atomizer chamber 201 and the first electrode through-hole 202. The heating element 320 seals and separates the second electrode through-hole 601 and the atomizer chamber 201. The end of the atomizer electrode 400 is located in the second electrode through-hole 601 and abuts against the heating element 320. The second seal 600 seals and separates the atomizer core 300 and the atomizer base 200, and only allows the first electrode through-hole 202 to communicate with the heating element 320 through the second electrode through-hole 601.

[0067] The second electrode through hole 601 enhances the circumferential sealing of the atomizing electrode 400. Optionally, the atomizing electrode 400 is embedded in the second electrode through hole 601 with an interference fit.

[0068] In one embodiment, the combination Figure 2 The second sealing member 600 has a mounting groove 602, and the second electrode through-hole 601 extends through the bottom of the mounting groove 602. The heating element 320 is mounted in the mounting groove 602 with a limited position. The mounting groove 602 further limits the installation position of the heating element 320, thereby reducing the position deviation of the heating element 320 due to vibration and improving the reliability of the contact and conduction between the heating element 320 and the atomizing electrode 400.

[0069] Optionally, the heating element 320 is flatly fitted with the bottom plane of the mounting groove 602 . On the one hand, this reduces the difficulty of processing the bottom plane of the mounting groove 602 . On the other hand, the flat fitting can increase the limiting effect of the heating element 320 and further improve the position stability of the heating element 320 .

[0070] In some embodiments, combined Figure 3 and Figure 4 The atomizing base 200 has a first air inlet channel 203 connected to the atomizing chamber 201. The first air inlet channel 203 is used to introduce external gas into the atomizing chamber 201, and then mix it with the atomized atomized liquid to form an aerosol, and then leave the atomizing component 10 through the air outlet channel 102.
