【Background technique】

The heating element is the core component of the HNB (heat not burn) aerosol generating device. There are three ways for the aerosol matrix to receive heat: heat conduction, heat convection, and heat radiation. Thermal convection mainly uses the surface of the heating wire to contact the air to heat up the flowing air around the heating wire, and then introduce the hot air into the heating chamber to heat the aerosol matrix through the suction airflow. Heat conduction directly uses the heating wire to directly contact the wall of the metal heating chamber to transfer heat into the heating chamber. The thermal radiation mainly uses the direct radiation of the heating wire to heat the aerosol matrix. Among the three methods, the energy utilization rate of heat convection is often low, and the heat is difficult to be fully utilized.

In this embodiment, the number of airflow passages 304 is multiple, in some embodiments it is 4, and multiple heating elements 300 are arranged in multiple airflow passages 304 for heating at the same time, which can increase the amount of air entering the atomization chamber 102 heat, increase the effective air outlet area and the heat exchange area between the heating element 300 and the air, and improve the atomization effect. The use of porous heating can also improve the uniformity of heating, and prevent the local temperature of the atomization chamber 102 from being too high, and the heating of other positions is not in place.

As shown in FIG. 7 to FIG. 9 , in one embodiment, the third through hole 201 is a straight through hole extending from the first surface 203 of the guide body 20 close to the atomizing body 10 to the second surface 204 away from the atomizing body 10 , may also be an oblique hole extending from the first surface 203 to the second surface 204 . In this embodiment, the third through hole 201 is a straight through hole extending from the first surface 203 to the second surface 204 , so that the airflow path of the airflow channel 304 can be shortened, thereby improving the atomization efficiency. In other embodiments, the third through hole 201 can also extend from the first surface 203 to the outer wall of the guide body 20 , which can also serve as the air flow channel 304 , which can be set according to specific needs, which is not limited in the present application.

In some embodiments, the heating element 30 is disposed in the gas flow channel 304 of the base body 11 for heating the gas flowing through the gas flow channel 304 . Wherein, the heating element 30 includes a plurality of heating elements 300 arranged in parallel, and the heating elements 300 extend from the air inlet end 3041 to the air outlet end 3042 .

Specifically, a plurality of heating elements 300 are arranged one by one in the plurality of third through holes 201 of the base body 11, for heating the gas flowing through the air flow channel 304, and the heated gas enters the atomization chamber 102 through the air flow channel 304, The aerosol matrix in the atomization chamber 102 is heated to generate aerosol for the user to inhale. Multiple heating elements 300 arranged in parallel can reduce the total resistance of the heating elements 300, reduce electric power, adapt to low power, and have high heat transfer efficiency. The heating element 300 is connected in parallel, which can effectively increase the heat exchange area between the heating element 300 and the air under the same resistance value, thereby enhancing the heat exchange effect.

It can be understood that the arrangement of the heating elements 300 in series can also achieve the purpose of uniformly heating the aerosol matrix in the atomization chamber 102 , therefore, in other embodiments, a plurality of heating elements 300 can also be arranged in series.

Please refer to Fig. 10 to Fig. 12, Fig. 10 is a schematic structural diagram of a heating element provided by this application; Fig. 11 is a schematic structural diagram of a heating element according to another embodiment provided by this application; Fig. 12 is another schematic diagram of a heating element provided by this application Schematic diagram of the structure of the heating element of the embodiment.

As shown in FIG. 10 , in this embodiment, the heating element 300 is a heating wire. The heating element 300 can be a structure that only includes the spiral heating section 301, that is to say, in this embodiment, the spiral heating section 301 is equivalent to the heating element 300, a plurality of heating elements 300 constitute the heating element 30, and the heating element 300 can be all Or partially disposed in the third through hole 201 .

As shown in Figure 11, in another embodiment, the heating element 300 may be a structure including a spiral heating section 301 and a lead wire 302, wherein the middle section is wound to form a spiral heating section 301, and the two ends are respectively formed with lead wires 302 and lead wires 302 includes a first lead 3021 and a second lead 3022 . In this embodiment, both the spiral heating section 301 and the lead wire 302 are components of the heating element 300 , and both can be used to heat the atomizing chamber 102 . A plurality of heating elements 300 constitute a heating element 30 , wherein the spiral heating section 301 is disposed in the third through hole 201 , and the first lead wire 3021 and the second lead wire 3022 extend out of the third through hole 201 .

As shown in FIG. 12 , in another embodiment, the heating element 300 can be wound around a middle section to form a spiral heating section 301 , and a first lead 3021 and a second lead 3022 are respectively formed at both ends. Specifically, the spiral heating section 301 is disposed in the third through hole 201 , and both the first lead wire 3021 and the second lead wire 3022 extend out of the third through hole 201 . The spiral heating section 301 is used to heat the airflow in the third through hole 201, so that the heated airflow enters the atomization chamber 102, and heats the aerosol matrix in the atomization chamber 102 to generate aerosol. One end of the first lead wire 3021 and the second lead wire 3022 are connected to the spiral heating section 301 , and the other end extends out of the third through hole 201 for connecting the power supply assembly 2 so that the power supply assembly 2 can supply power to the heating element 300 .

Further, the middle section of the heating element 300 is wound around to form two spiral heating sections 301, and the two spiral heating sections 301 are respectively arranged in two adjacent third through holes 201, thus increasing the length of the heating element 300, thereby The contact area between the spiral heating section 301 and the air is increased. It can be understood that in this embodiment, one heating wire can be wound to form two spiral heating sections 301 , or two heating wires wound into spiral heating sections 301 can be connected in series to form a longer heating body 300 . Specifically, the spiral heating section constituting the two heating elements 300 arranged in parallel may include two sub-heating elements, each of which is arranged in series, and then the two sub-heating elements arranged in series are arranged in parallel. Both arrangements of the heating element 300 can achieve the effect of increasing the length of the heating element 300 and improving the heat exchange efficiency.

As shown in FIG. 8 and FIG. 12 , the ends of the two spiral heating sections 301 close to the atomizing body 10 are connected to each other to form a connection section 303 , and the ends away from the atomizing body 10 are respectively connected to the first lead wire 3021 and the second lead wire 3022 .

Specifically, as mentioned above, the two helical heating sections 301 can be formed by directly winding one heating element 300, or two heating elements 300 can be respectively wound as the spiral heating section 301 and then close to the atomizing body 10. Connect at one end. Further, the connecting section 303 of the two spiral heating sections 301 is fixed on the end surface or side wall of the guide body 20 close to the atomizing body 10, which can improve the installation stability of the two spiral heating sections 301 and prevent the spiral heating section 301 from The end close to the atomizing body 10 is in contact with the side wall of the third through hole 201 , causing waste of heat. By adopting multiple heating elements 300 for heating, the temperature of each heating element 300 will not be too high, thereby reducing the proportion of radiation in energy consumption and improving heating uniformity.

In this embodiment, multiple heating wires are used to increase the heat exchange area between the spiral heating section 301 and the air, and at the same time make the flow field of hot air entering the atomization chamber 102 more uniform, avoiding local high temperature, and the aerosol matrix can Heat evenly.

At the same time, as shown in Figure 9, the spiral heating section 301 of the present application extends from the inlet end 3041 to the air outlet end 3042 and is arranged perpendicular to the bottom wall of the first groove 101, so that the air flow can span the entire heating wire, and the gas and heat generation The wire contact is more sufficient, and the efficiency of air heating is higher. The air flow channel 304 in the guide body 20 is a heating channel, which shortens the heat transfer path and reduces heat loss. It can be understood that the spiral heating section 301 may not be arranged perpendicular to the bottom wall of the first groove 101 , as long as it extends from the air inlet end 3041 to the air outlet end 3042 .

Please refer to Figure 20 to Figure 22, Figure 20 is a schematic diagram of the single-hole heating structure of the comparative example provided by the application; Figure 21 is a comparison diagram of the simulated temperature field between the porous heating structure and the single-hole heating structure; Figure 22 is the porous heating structure and Comparison chart of heating curves of single-hole heating structure.

As an embodiment of the present application, the guide body 20 has a four-hole structure, specifically including four third through holes 201 . The two heating wires are connected in parallel as shown in FIG. 12 , and each spiral heating section 301 is set in a third through hole 201 , that is, the third through hole 201 serves as the air inlet 207 and the heating chamber 200 at the same time. In this example, the single-hole heating structure heating wire is slightly longer than the four-hole heating wire, so the connection method of two heating wires in parallel can provide more heat for the atomization chamber 102, while the spiral heating section 301 The overall resistance value can be maintained in a lower numerical range, thereby effectively controlling the total resistance value.

As an embodiment of the present application, the guide body 20 has a four-hole structure, specifically including four third through holes 201 . The two heating wires are connected in parallel as shown in FIG. 12 , and each spiral heating section 301 is set in a third through hole 201 , that is, the third through hole 201 serves as the air inlet 207 and the heating chamber 200 at the same time. Using the connection method of heating wires in parallel can maintain the resistance value within a lower value range, thereby effectively controlling the total resistance value.

It can be clearly seen from Fig. 22 that in the single-hole heating structure of the prior art, when only one heating wire is used, the convective heat exchange efficiency with the air is low, and the temperature of the air after reaching the atomizing chamber 102 is obviously low in a porous heating structure. And due to the limitation of the single hole, the hot air tends to gather at the center of the atomization chamber 102, and only heats the aerosol matrix at the center of the atomization chamber 102, causing the aerosol matrix at this position to be easily burnt. However, in the porous heating structure of the present application, there are multiple airflow channels 304 (201) to introduce hot air into the atomization chamber 102, so that the hot air in the atomization chamber 102 is more uniform than the single-hole heating structure. Specifically, Figure 22 is a comparison of the temperature rise curve of the four-hole heating structure and the existing single-hole heating structure at the P3 test point. From Figure 22, it can be seen that when the sixth port is pumped, the four-hole heating structure is 45°C higher than the existing single-hole heating structure , When the first suction is drawn, the four-hole heating structure is 20°C higher than the existing single-hole heating structure. Therefore, the heating slope of the four-hole heating structure is larger than the heating slope of the existing single-hole heating structure, the heating rate is faster, and the peak temperature is higher.

It can be clearly seen from Fig. 20 and Fig. 21 that due to the change of the structure of the guide body 20, the heating cavity 200 of the porous heating structure is the air flow channel 304, and no additional air flow channel is needed, thereby reducing heat loss.

Table 1 shows the parameter comparison between the porous heating structure and the single-hole heating structure when using the same electric power (taking four holes as an example). It can be clearly seen that the performance of the porous heating structure is significantly higher than that of the single-hole heating structure.

The current air heating technology is mainly to place a heating wire in the guide body 20 to heat up the air in the guide body 20 and guide the hot air to heat the target substance (the target substance in this application is specifically an aerosol matrix). Therefore, in this technology, the heat exchange efficiency between the heating wire and the air is very important. In order to improve the heat exchange efficiency between the heating wire and the air, the inventor of the present application proposes that the heating wire should be suspended as much as possible to ensure that the heat of the heating wire can be exchanged with the air to the greatest extent instead of being conducted to other components. At present, there is no better way to suspend and fix the heating wire in the guide body 20 , so the heating wire is easily attached to the ceramic wall of the guide body 20 . Once the heating wire is attached to the wall, the heat of the heating wire is easily conducted to the ceramic body of the guide body 20 . On the one hand, the temperature of the heating wire is greatly reduced, which affects the heat exchange efficiency between the heating wire and the surrounding air, resulting in heat loss. On the other hand, the temperature of the diversion body 20 rises substantially, causing potential safety hazards to other structures connected to the diversion body 20 , such as the silicone seal ring and the casing 3 .

In order to solve the above problems, the present application sets a limiter 90 on the atomization assembly 1 to limit the heating element 300 so that the spiral heating section 301 of the heating element 300 and the hole wall of the third through hole 201 of the guide body 20 are not separated. The contact, that is, is suspended in the third through hole 201 .

Specifically, the limiting member 90 may be disposed at an end of the third through hole 201 away from the atomizing chamber 102 . The limiting member 90 connects the first lead 3021 and the second lead 3022 and limits the spiral heating section 301 , so that the spiral heating section 301 of the heating element 300 is spaced apart from the side wall of the third through hole 201 . That is to say, the limiting member 90 limits the spiral heating section 301 within a certain range, which can keep a certain gap between the spiral heating section 301 and the side wall of the third through hole 201, and reduce the heat transfer of the spiral heating section 301 to the guide fluid 20. The ceramic body is conductive, so that more heat from the heating wire is transferred to the air and further transferred to the atomizing chamber 102 .

Please refer to Fig. 13 to Fig. 19, Fig. 13 is a schematic structural view of the limiting member of the first embodiment provided by the present application; Fig. 14 is a schematic structural view of the limiting member of the second embodiment provided by the present application; Fig. 21 is a schematic structural view of the limiting member of the present application A schematic structural diagram of the limiting member of the third embodiment provided by the application; FIG. 22 is another structural schematic diagram of the limiting member of the third embodiment provided by the application; FIG. 17 is a schematic diagram of the limiting member of the fourth embodiment provided by the application Schematic structural diagram of the positioning member; FIG. 18 is a schematic structural view of the limiting member of the fifth embodiment provided by the present application; FIG. 19 is a schematic structural view of the limiting member of the sixth embodiment provided by the present application.

As shown in FIG. 13 , in the first embodiment, the limiting member 90 includes a limiting rod 91 , and the limiting rod 91 is arranged at the end of the third through hole 201 away from the atomizing chamber 102 , and is connected to the end of the third through hole 201 . side wall connection. Wherein, the limiting rod 91 has a limiting hole 911 through which the first lead wire 3021 and the second lead wire 3022 pass through, so that the limiting rod 91 can limit the helical heating section 301 .

Specifically, the limiting rod 91 can be independently provided, and the two ends of the limiting rod 91 are engaged or bonded to the side wall of the third through hole 201 or the surface of the guide body 20 away from the atomizing body 10 . The limiting rod 91 can also be integrally formed with the guide body 20 , so that the step of connecting the limiting rod 91 with the third through hole 201 can be omitted, and the stability of the integral molding is higher. Specifically, it can be set as required, and this application does not limit it. The limiting hole 911 may be a through hole or a notch. Specifically, the limiting hole 911 can be opened in the middle or both sides of the limiting rod 91, as long as the first lead wire 3021 and the second lead wire 3022 can pass through the middle of the limiting hole 911, so that the limiting hole 911 The spiral heating section 301 is limited so that there is a gap and no contact between the spiral heating section 301 and the side wall of the third through hole 201 . The limit rod 91 corresponds to the number of the limit hole 911, and corresponds to the number of the first lead wire 3021 and the second lead wire 3022, so as to realize the effective limit of the limit rod 91 and the limit hole 911 to the spiral heating section 301 . The helical heating section 301 is limited by the limiting rod 91 and the limiting hole 911, which can prevent the heating wire from shifting horizontally and vertically, and prevent the spiral heating section 301 of the heating wire from moving toward a side close to the atomizing body 10 during use. The side slides or bends so as to contact the inner wall of the third through hole 201 .

Specifically, in this embodiment, the metal sheet 92 needs to straddle the port of the third through hole 201, and cannot be completely arranged on the surface of the guide body 20 away from the atomizing body 10. The reason is that if the metal sheet 92 is all arranged on the guide On the surface of the fluid 20 away from the atomizing body 10, after being welded to the spiral heating section 301 of the heating element 300, the spiral heating section 301 will contact the side wall of the third through hole 201, so that the limit of the spiral heating section 301 cannot be achieved. For the purpose of having a gap between the spiral heating section 301 and the side wall of the third through hole 201 . Therefore, the metal sheet 92 needs to straddle the port of the third through hole 201 , but the position and angle of straddling the port can be set as required. The positive electrodes of multiple heating elements 300 can be welded to the same metal sheet 92 , or the positive electrodes of each heating element 300 can be welded to one metal sheet 92 . The negative electrodes of multiple heating elements 300 can be welded to the same metal sheet 92 , or the negative electrodes of each heating element 300 can be welded to one metal sheet 92 . In addition, the two ends of the metal sheet 92 can be embedded and clamped or glued to the end surface of the guide body 20 away from the atomizing body 10, and the middle part of the metal sheet 92 is set across the port of the third through hole 201, so that the metal sheet 92 will not move with the shaking of the spiral heating section 301, so as to achieve the purpose of fixing and limiting the spiral heating section 301.
