The housing 1 is provided with a liquid storage chamber 11 for storing a liquid matrix, and the atomizing component 2 is in fluid communication with the liquid storage chamber 11, thereby atomizing the liquid matrix to generate an aerosol.

[0097] In some embodiments, the atomizer 100 is a component of an aerosol generating device, which includes a power supply assembly (not shown) electrically connected to the atomizer 100 to provide electrical power to the atomizer 100, thereby enabling the atomizing assembly 2 to atomize the liquid matrix.

[0102] The liquid matrix stored in different liquid storage chambers 11 can be different, so that when the atomizing component 2 atomizes the liquid matrix provided by different liquid storage chambers 11, it can produce aerosols with different flavors or aromas. The aerosol generating matrix stored in different liquid storage chambers 11 can be the same, so that when the atomizing component 2 atomizes the liquid matrix provided by different liquid storage chambers 11, it can produce aerosols with the same flavor or aroma.

[0103] In some embodiments, the atomizer 100 further includes a liquid storage element 3, which has a large number of pores and is capable of adsorbing a large amount of liquid matrix.

[0107] In some embodiments, the atomizer 100 further includes a mouthpiece 12 having an inhalation port 121 for discharging the aerosol generated by the atomizer 100. The mouthpiece 12 can be held in the mouth by a user, and when held in the mouth, the inhalation port 121 is positioned towards the user's oral cavity, so that the user can inhale the aerosol generated by the atomizer 100 by inhaling through the mouthpiece 12. The aerosol channel is in fluid communication with the inhalation port 121 to guide the aerosol to the inhalation port 121.

[0108] Furthermore, the suction nozzle 12 and the housing 1 are integrally injection molded. Even further, one end of the air guide tube 4 is connected to the suction nozzle 12 and communicates with the air intake 121, and the suction nozzle 12, the housing 1 and the air guide tube 4 are integrally injection molded.

[0109] In some embodiments, reference may be made to Figure 2 and Figure 3The heating element 21 includes a first heating part 211, a second heating part 212, and a connecting part 213. The connecting part 213 is electrically connected to the first heating part 211 and the second heating part 212, so that the first heating part 211 and the second heating part 212 can be assembled as a whole. Furthermore, the first heating part 211 and the second heating part 212 are non-coplanar and spaced apart, so that the heating element 21 has a large atomization area.

[0110] In some embodiments, the heating element 21 is formed by stamping a metal sheet to reduce the production cost of the heating element 21 and improve the production efficiency of the heating element 21.

[0111] In some embodiments, the first heating portion 211 and the connecting portion 213 have the same thickness D. In some embodiments, the second heating portion 212 and the connecting portion 213 have the same thickness D. In some embodiments, the first heating portion 211 and the second heating portion 212 have the same thickness D.

[0112] In some embodiments, the first heating part 211 and the connecting part 213 have the same height H. In some embodiments, the second heating part 212 and the connecting part 213 have the same height H. In some embodiments, the first heating part 211 and the second heating part 212 have the same height H.

[0114] In some embodiments, the first heating element 211 and the second heating element 212 have the same structural features. Furthermore, the first heating element 211 and the second heating element 212 have the same dimensions. Even further, the heating element 21 has a surface-symmetrical structure or a centrosymmetric structure.

[0115] In some embodiments, reference may be made to Figure 2 and Figure 3 The first heating part 211 and the second heating part 212 are respectively connected to the opposite ends of the connecting part 213, and the first heating part 211 and the second heating part 212 extend toward the same side of the connecting part 213, so that the first heating part 211 and the second heating part 212 are arranged approximately face to face.

[0116] In some embodiments, the connecting portion 213 is formed by bending the first heating portion 211 and the second heating portion 212 from the same metal sheet, thereby providing lateral support between the first heating portion 211 and the second heating portion 212. The ends of the first heating portion 211 and the second heating portion 212 opposite to the connecting portion 213 are free ends. After assembly, the free ends are anchored by the first bracket 6, so that the connecting portion 213 can provide support force to make the first heating portion 211 and the second heating portion 212 approach or adhere closely to the corresponding liquid guiding element 22, so that the fit between the first heating portion 211 and the second heating portion 212 and the corresponding liquid guiding element 22 is tighter, preventing the heating element from warping or twisting during the heating process, which helps to improve the efficiency of the first heating portion 211 and the second heating portion 212 in heating and atomizing the liquid matrix on the liquid guiding element 22.

[0117] refer to Figure 2 and Figure 3 As one example of the heating element 21, the first heating portion 211 is disposed perpendicular to the connecting portion 213, and the second heating portion 212 is disposed perpendicular to the connecting portion 213, thereby constructing the heating element 21 into a U-shaped structure. In one example, the first heating portion 211 and the second heating portion 212 are disposed parallel to each other, and both the first heating portion 211 and the second heating portion 212 extend in a plane to form a flat heating portion; and in other examples, the first heating portion 211 and the second heating portion 212 are arranged to extend in a curved surface, thereby connecting with the connecting portion 213 and constructing a C-shaped structure. In another example, the first heating portion 211 and the second heating portion 212 are arranged at an angle to each other. The first heating portion 211 and the second heating portion 212 may form an inclined angle in the longitudinal direction, for example, the extending direction of the first heating portion 211 and the second heating portion 212 is inclined at an acute angle to the axis of the aerosol channel. The first heating part 211 and the second heating part 212 can also form an inclined angle in the lateral direction. For example, the first heating part 211 and the second heating part 212 are inclined to each other, and the angle between the two and the connecting part 213 is less than 90 degrees.

[0118] In some embodiments, the average resistance value per unit area of ​​the first heating part 211 and the average resistance value per unit area of ​​the second heating part 212 are greater than the average resistance value per unit area of ​​the connecting part 213.

[0119] For example, you can refer to Figure 2 and Figure 3 The first heating part 211 includes a mesh structure, or the first heating part 211 is provided with multiple through holes to increase the average resistance value per unit area of ​​the first heating part 211. Similarly, the second heating part 212 includes a mesh structure, or the second heating part 212 is provided with multiple through holes to increase the average resistance value per unit area of ​​the second heating part 212.

[0120] In some embodiments, reference may be made to Figure 2 and Figure 3 The heating element 21 includes a first pin 214 and a second pin 215, which are used for electrical connection with a power supply. The first heating part 211 and the second heating part 212 are electrically connected between the first pin 214 and the second pin 215, so that the first heating part 211 and the second heating part 212 can be connected in series with the power supply.

[0121] Furthermore, the heating element 21 also includes a third pin 216 connected to the connection portion 213, the first heating portion 211 is electrically connected between the first pin 214 and the third pin 216, and the second heating portion 212 is electrically connected between the second pin 215 and the third pin 216.

[0122] The first pin 214 and the second pin 215 can be electrically connected to the same electrode of the power supply, and the third pin 216 can be electrically connected to the other electrode of the power supply, so that the third pin 216 becomes the common positive or common negative pin of the first heating part 211 and the second heating part 212.

[0123] In some embodiments, the controller can independently control the circuit connection between the first pin 214 and the power supply and independently control the circuit connection between the second pin 215 and the power supply, thereby independently controlling the power supply to provide electrical power to the first heating part 211 and the second heating part 212, so that the first heating part 211 and the second heating part 212 can independently heat the atomized liquid matrix.

[0124] In some embodiments, reference may be made to Figures 4-8 The atomizer 100 also includes a first support 6 and an electrode 7, which is used to electrically connect pins and a power source. The number of electrodes 7 can be the same as the number of pins. For example, when including a first pin 214, a second pin 215, and a third pin 216, it can include a first electrode electrically connected to the first pin 214, a second electrode electrically connected to the second pin 215, and a third electrode electrically connected to the third pin 216.

[0125] The preferred electrode 7 and the atomizing component 2 are both held on the first support 6.

[0126] In some embodiments, reference may be made to Figure 7The first bracket 6 is provided with a stepped hole 61 with a step 611. The first pin 214 includes a first bent end 2141, which is located in the stepped hole 61 and abuts against the step 611, so that the step 611 is located between the first bent end 2141 and the first heating part 211. The electrode 7 is riveted in the stepped hole 61 and abuts against the first bent end 2141, so that the electrode 7 and the first pin 214 can maintain a stable electrical connection without welding. At the same time, the first bent end 2141 can also prevent the first pin 2141 from exiting the stepped hole 61 before the electrode 7 is riveted into the stepped hole 61.

[0127] The second pin 215 can have the same structural features as the first pin 214. The third pin 216 can have the same structural features as the first pin 214. The number of stepped holes 61 can be the same as the number of electrodes 7, and multiple stepped holes 61 are arranged in a one-to-one correspondence with multiple electrodes 7.

[0128] In some embodiments, reference may be made to Figure 8 The electrode 7 includes a first electrode 71 electrically connected to the first pin 214, a second electrode 72 electrically connected to the second pin 215, and a third electrode 73 electrically connected to the third pin 216. The third electrode 73 is elongated and has a symmetry line A. The first electrode 214 and the second electrode 215 are arranged alternately and symmetrically with respect to the symmetry line A of the third electrode 73. This allows the atomizer 100 to have multiple different electrical connection directions with the power supply assembly. For example, the atomizer 100 can be inserted into the power supply assembly in two different orientations with a 180-degree rotation, without the need for a foolproof design. In this embodiment, the third electrode 73 is preferably electrically connected to the connection portion 213 of the heating element 21, the first electrode 71 is electrically connected to the first heating portion 211 of the heating element 21, and the second electrode 72 is electrically connected to the second heating portion 211 of the heating element 21.

[0129] In some embodiments, reference may be made to Figure 2 and Figure 3 The heating element 21 includes a hook-shaped fixing part 217, which is used to anchor or hold the heating element 21 on the first bracket 6.

[0130] Furthermore, the first bracket 6 is partially fitted into the hook-shaped fixing part 217, thereby holding the heating element 21 on the first bracket 6.

[0131] The air inlet 121 is located at the proximal end of the atomizer 100, and the hook-shaped fixing part 217 is preferably located at the proximal end of the heating element 21, so that the first bracket 6 can overcome the gravity of the heating element 21 and support the heating element 21.

[0132] In some embodiments, reference may be made to Figure 2and Figure 3 The fixing part 217 includes a first fixing part 2171 and a second fixing part 2172. The first fixing part 2171 and the first heating part 211 are disposed on the same side, and the second fixing part 2172 and the second heating part 212 are disposed on the same side, so as to ensure that the first heating part 211 can be disposed adjacent to the liquid guiding element 22, and to ensure that the second heating part 212 can be disposed adjacent to the liquid guiding element 22.

[0133] The fluid guiding element 22 can also be held on the first support 6. For example, the first support 6 is provided with a window that is in fluid communication with the liquid storage chamber, and at least a portion of the fluid guiding element 22 can be interference-filled in the window to maintain connection with the first support 6.

[0134] In some embodiments, reference may be made to Figure 5 The liquid guiding element 22 includes a first liquid guiding element 221 and a second liquid guiding element 222, which are held at intervals on the first support 6. A first heating element 211 is disposed adjacent to the first liquid guiding element 221, so that the first heating element 211 is close to or in contact with the first liquid guiding element 221, and is primarily used to heat the liquid matrix in the first liquid guiding element 221 to generate an aerosol. Similarly, a second heating element 212 is disposed adjacent to the second liquid guiding element 222, such that the second heating element 212 is primarily used to heat the liquid matrix in the second liquid guiding element 222 to generate an aerosol.

[0135] Further, you can refer to Figure 5 The first support 6 is provided with a first window 62 and a second window 63 spaced apart from each other. At least a portion of the first liquid guiding element 221 is held in the first window 62, and at least a portion of the second liquid guiding element 222 is held in the second window 63, thereby holding the first liquid guiding element 221 and the second liquid guiding element 222 separately. Preferably, the first window 62 and the second window 63 are arranged opposite to each other or symmetrically.

[0136] In some embodiments, reference may be made to Figure 4 and Figure 5 An atomizing chamber 64 for releasing aerosols and providing airflow is defined between the first heating element 211 and the second heating element 212. The atomizing chamber 64 is in fluid communication with the intake port 121. Heating by the heating element 21 causes volatile substances generated by the evaporation of the liquid matrix to combine with air mainly in the atomizing chamber 64 to form an aerosol. The atomizing chamber 64 may be defined in the first support 6.

[0137] The first heating part 211 and the second heating part 212 can be arranged facing the same atomizing chamber 64, so that the aerosol generated by the first heating part 211 heating the liquid matrix and the aerosol generated by the second heating part 212 heating the liquid matrix are mainly formed in the same atomizing chamber 64, and then the aerosol formed by either heating part can flow from the same atomizing chamber 64 to the air intake 121.

[0138] In some embodiments, when the liquid storage chamber 11 includes a first liquid storage chamber 111 and a second liquid storage chamber 112 that are isolated from each other, the first liquid guiding element 221 is configured to conduct the liquid matrix stored in the first liquid storage chamber 111 to the first heating part 211 for heating and atomization, and the second liquid guiding element 222 is configured to conduct the liquid matrix stored in the second liquid storage chamber 112 to the second heating part 212 for heating and atomization. Since the first heating part 211 and the second heating part 212 are disposed facing the same atomization chamber 64, when the first heating part 211 and the second heating part 212 simultaneously receive electrical power for heating, the aerosol generated by the first heating part 211 through heating and atomizing the liquid matrix stored in the first liquid storage chamber 111 can mix with the aerosol generated by the second heating part 212 through heating and atomizing the liquid matrix stored in the second liquid storage chamber 112 in the atomization chamber 64. In some alternative examples, the liquid matrix stored in the first liquid storage chamber 111 and the second liquid storage chamber 112 has different compositions or types, thereby providing the user with a richer mixed flavor when the first heating unit 211 and the second heating unit 212 are working simultaneously.

[0139] Of course, the controller can control the first heating part 211 and the second heating part 212 to heat up individually or both at the same time by controlling the on and off of the circuit between the three pins and the power supply.

[0140] In some embodiments, the central axis of the atomizing chamber 64 is substantially coincident with the central axis of the aerosol channel to reduce the obstruction of aerosol flowing from the atomizing chamber 64 into the intake port 121, reduce the generation of condensate, and reduce the retention loss of aerosol during the process of flowing from the atomizing chamber 64 into the intake port 121.

[0141] In such Figure 1 In the illustrated embodiment, the air outlet of the atomizing chamber 64 is located at the proximal end of the atomizing chamber 64. Furthermore, the air outlet of the atomizing chamber 64 is positioned towards the direction of the air inlet 121.

[0142] In some embodiments, reference may be made to Figure 1 The first heating element 211 and the second heating element 212 are both arranged substantially parallel to the aerosol channel. In other embodiments, the first heating element 211 and / or the second heating element 212 are arranged inclined to the central axis of the aerosol channel.

[0143] In some embodiments, reference may be made to Figure 1 The atomizing chamber 64 and the air inlet 121 or the aerosol channel are set on the same central axis.

[0144] In some embodiments, the cross-sectional area of ​​the atomizing chamber 64 is approximately the same as the ventilation area of ​​the aerosol channel, or the width W1 of the atomizing chamber 64 is approximately the same as the width or inner diameter D1 of the aerosol channel, so as to reduce the obstruction of aerosol flowing from the atomizing chamber 64 into the aerosol channel and reduce the loss of aerosol during the process of aerosol flowing from the atomizing chamber 64 into the aerosol channel.

[0145] In some embodiments, reference may be made to Figure 1 The first support 6 has a support portion 65, which is disposed facing the air guide pipe 4 or facing the air inlet 121. The support portion 65 is used to support the atomizing assembly 2. An airflow inlet 66 communicating with the atomizing chamber 64 is opened on the support portion 65, and outside air can be guided into the atomizing chamber 64 by the airflow inlet 66. The airflow inlet 66 can be located between the first window 62 and the second window 63, or between the first heating part 211 and the second heating part 212. The airflow inlet 66 and the air outlet of the atomizing chamber 64 can be located on opposite sides of the atomizing chamber 64.

[0146] Furthermore, the airflow inlet 66 includes a first airflow inlet 661 disposed adjacent to the first heating section 211 to guide airflow across the surface of the first heating section 211, thereby increasing the mixing efficiency of volatile substances generated by the atomized liquid matrix of the first heating section 211 with air, and also preventing turbulence from forming near the surface of the first heating section 211 or in the atomization chamber 64. Even further, the airflow inlet 66 also includes a second airflow inlet 662 disposed adjacent to the second heating section 212 to guide airflow across the surface of the second heating section 212, thereby increasing the mixing efficiency of volatile substances generated by the atomized liquid matrix of the second heating section 212 with air, and also preventing turbulence from forming near the surface of the second heating section 212 or in the atomization chamber 64.

[0147] In some embodiments, reference may be made to Figure 4 and Figure 6 The first support 6 includes a first sidewall 67 for defining the atomizing chamber, and a first positioning groove 671 is provided on the first sidewall 67. The heating element 21 includes a first positioning part 218 and a first positioning part 219 disposed in the first positioning groove 671. When assembling the heating element 21 and the first support 6, the heating element 21 can be positioned by the first positioning part 218 corresponding to the first positioning groove 671, so as to prevent the heating element 21 from twisting or misaligning during the assembly process, so that the heating element 21 can be accurately engaged on the first support 6, which helps to improve the yield rate.

[0148] Furthermore, a second positioning groove 762 is provided on the first sidewall 67, and the heating element 21 also includes a second positioning part 219 disposed in the second positioning groove 672. By providing multiple positioning parts and multiple positioning grooves in a one-to-one correspondence, the engagement accuracy and engagement yield between the heating element 21 and the first bracket 6 are further improved.

[0149] In such Figure 3 In the illustrated embodiment, a first positioning part 218 is connected to the end of the first heating part 211 opposite to the connecting part 213, thereby the first positioning part 218 helps to position the first heating part 211. A second positioning part 219 is connected to the end of the second heating part 212 opposite to the connecting part 213, thereby the second positioning part 219 helps to position the second heating part 212.

[0150] In some embodiments of this application, the first liquid guiding element 221 is first installed and held in the first window 62, and the second liquid guiding element 222 is installed and held in the second window 63. Then, the heating element 21 is placed in the atomizing chamber 64, and the first heating element 211 is positioned so that it is adjacent to the first liquid guiding element 221 by engaging with the first positioning groove 671 through the first positioning part 218. The first heating element 211 is positioned so that it is adjacent to the first liquid guiding element 221 by interfering with the first support 6 through the first fixing part 2171. This allows the first heating element 211 to remain close to or in contact with the first liquid guiding element 221, and also prevents the first heating element 211 from becoming loose. At the same time, the second heating element 212 is positioned so that it is adjacent to the second liquid guiding element 222 by engaging with the second positioning groove 672 through the second positioning part 219. The second fixing part 2172 is positioned so that it is adjacent to the second liquid guiding element 222 by interfering with the first support 6 through the second fixing part 2172. This allows the second heating element 212 to remain close to or in contact with the second liquid guiding element 222, and also prevents the second heating element 212 from becoming loose.

[0151] In such Figure 3 In the embodiment shown, the first pin 214 is connected to the first positioning part 218, and the second pin 215 is connected to the second positioning part 219.

[0152] In some embodiments, reference may be made to Figure 4 The connecting portion 213 is disposed facing the first sidewall 67. Alternatively, the first support 6 may also include a second sidewall 68 disposed opposite to the first sidewall 67, the second sidewall 68 defining a portion of the boundary of the atomizing chamber 64, and the connecting portion 213 disposed adjacent to the second sidewall 68, preferably the connecting portion 213 being tightly fitted against the second sidewall 68. The connecting portion 213 is located between the first sidewall 67 and the second sidewall 68. The atomizing chamber 64 is disposed between the connecting portion 213 and the first sidewall 67.

[0153] Furthermore, the first window 62 and the second window 63 are both disposed between the first sidewall 67 and the second sidewall 68, and the atomizing chamber 64 is located between the first window 62 and the second window 63.

[0154] In some embodiments, reference may be made to Figure 1 , Figure 8 and Figure 9 The atomizer 100 also includes a sealing seat 5, and a liquid storage chamber 11 is defined between the housing 1 and the sealing seat 5, thereby sealing the liquid storage chamber 11.

[0155] The sealing seat 5 may include a second support 51 and a seal 52, with at least a portion of the second support 51 disposed within and connected to the housing 1, and at least a portion of the seal 52 located between the second support 51 and the housing 1 to provide a seal between the second support 51 and the housing 1 to prevent leakage of the liquid matrix in the reservoir 11.

[0156] In some embodiments, the first bracket 6 is connected to the sealing seat 5, such that the first bracket 6, the sealing seat 5 and the atomizing component 2 held on the first bracket 6 form a whole, which can then be assembled with the housing 1, which helps to simplify the process flow of the atomizer 100, improve the production efficiency of the atomizer 100 and reduce the production cost of the atomizer 100.

[0157] Further, you can refer to Figure 1 One end of the air guide tube 4 is connected to the air inlet 121, and the other end is connected to the sealing seat 5. The air guide tube 4 is in fluid communication with the air inlet 121 and the atomizing chamber 64.

[0158] In some embodiments, reference may be made to Figure 8 and Figure 9 The sealing seat 5 is provided with a first liquid guiding groove 53 communicating with the liquid storage chamber 11, a second liquid guiding groove 54 communicating with the liquid storage chamber 11, and a receiving space 55 for receiving at least a portion of the atomizing component 2. The sealing seat 5 also includes a first partition wall 56 located between the first liquid guiding groove 53 and the receiving space 55 and a second partition wall 57 located between the second liquid guiding groove 54 and the receiving space 55.

[0159] Specifically, the receiving space 55 is located on the side of the second support 52 away from the liquid storage chamber 11.

[0160] Furthermore, when the liquid storage chamber 11 includes a first liquid storage chamber 111 and a second liquid storage chamber 112 that are isolated from each other, the first liquid guiding groove 53 guides liquid to connect the first liquid storage chamber 111 and the first liquid guiding element 221, and the second liquid guiding groove 54 guides liquid to connect the second liquid storage chamber 112 and the second liquid guiding element 222.

[0161] In some embodiments, reference may be made to Figure 4 The atomizing chamber 64 is roughly rectangular or square.

[0162] In some embodiments, reference may be made to Figure 2 and Figure 3 A first heat dissipation hole 23 is provided on the first positioning part 218 and / or the second positioning part to increase the thermal resistance between the first positioning part 218 and / or the second positioning part and the wall of the corresponding positioning groove, thereby preventing high temperature damage to the wall of the positioning groove and protecting the first bracket 6.

[0163] In some embodiments, reference may be made to Figure 3 The heating element 21 also includes a first reinforcing part 26 that connects the first heating part 211 and the second connecting part 213.

[0164] The first reinforcing part 26 can be disposed on the same side of the first heating part 211, which can prevent the first heating part 211 from deforming when it interferes with the first support 6. The first reinforcing part 26 can be disposed on the same plane as the first heating part 211. The first reinforcing part 26 can abut against the side wall of the first support 6. Furthermore, the first reinforcing part 26 can provide a supporting force to the first heating part 211, so that the first heating part 211 is disposed close to or in close contact with the liquid guiding element 22.

[0165] A second heat dissipation hole 24 is provided on the first reinforcing part 26 to increase the thermal resistance between the first reinforcing part 26 and the first bracket 6, thereby preventing the first bracket 6 from melting at high temperature.

[0166] In some embodiments, reference may be made to Figure 3 The heating element 21 also includes a second reinforcing portion 27 connecting the second heating portion 212 and the second connecting portion 213.

The second reinforcing portion 27 may be symmetrically arranged with the first reinforcing portion 26.

[0167] The second reinforcing part 27 can be disposed on the same side of the second heating part 212, which can prevent the second heating part 212 from deforming when it interferes with the first bracket 6. The second reinforcing part 27 can be disposed coplanarly with the second heating part 212. The second reinforcing part 27 can abut against the side wall of the second bracket 6. Furthermore, the second reinforcing part 27 can provide a supporting force to the second heating part 212, so that the second heating part 212 is disposed close to or in close contact with the liquid guiding element 22.

[0168] A third heat dissipation hole 25 is provided on the second reinforcing part 27 to increase the thermal resistance between the second reinforcing part 27 and the second bracket 25, thereby preventing the second bracket 6 from melting at high temperature.

Alternatively, the diameter of the first heat dissipation hole 23 is larger than the diameter of the second heat dissipation hole 24 and / or the third heat dissipation hole 25.

[0185] An atomizing component for atomizing a liquid matrix to generate an aerosol. The atomizing component includes:

[0186] Heating element 21a is used to heat a liquid matrix to generate an aerosol.

[0187] The heating element 21a includes:

[0188] The first heating element 211a, the second heating element 212a, and the connecting element 213a are electrically connected, allowing the first heating element 211a and the second heating element 212a to be assembled as a single unit. Furthermore, the first heating element 211a and the second heating element 212a are non-coplanar and spaced apart, resulting in a larger atomization area for the heating element 21a.

[0189] In some embodiments, the first heating element 211a and the second heating element 212a have the same structural features. Furthermore, the first heating element 211a and the second heating element 212a have the same dimensions. Even further, the heating element 21a has a surface-symmetrical structure or a centrally symmetrical structure.
