The first main electrode and the third main electrode are disposed on the bracket, and the second main electrode and the third main electrode are installed at different heights in the opening direction of the accommodating cavity, so that when the atomizer is inserted into multiple positions in the accommodating cavity in the opening direction, the first main electrode is conductive to the atomizer, and one of the second main electrode and the third main electrode is conductive to the atomizer; or the first main electrode, the second main electrode, and the third main electrode are each conductive to the atomizer; thereby making the atomization resistance of the atomizer different at different positions.

[0006] In one specific embodiment, the mounting height of the second host electrode in the opening direction of the accommodating cavity is greater than the mounting height of the third host electrode in the opening direction of the accommodating cavity, and the second host electrode is telescopically configurable relative to the bracket.

[0009] In one specific embodiment, the housing is provided with a plurality of main unit limiting parts on the side near the receiving cavity. The plurality of main unit limiting parts are arranged sequentially along the opening direction of the receiving cavity, and each main unit limiting part is used to limit the atomizer at each position.

[0010] In one specific embodiment, the main unit limiting part is a main unit engaging part, which is used to engage with the atomizer.

[0011] In one specific embodiment, the main unit limiting part is a magnetic limiting part, which is used to adsorb the atomizer.

[0012] To solve the above-mentioned technical problems, another technical solution adopted in this application is: providing an atomizer for an aerosol generating device, the atomizer comprising: a liquid storage chamber, including a bottom wall and a peripheral side wall, the bottom wall and the peripheral side wall being connected to form a liquid storage cavity, the liquid storage cavity being used to store an aerosol matrix; an atomizing core, disposed within the liquid storage cavity, the atomizing core being used to absorb and heat the aerosol matrix to generate an aerosol; and an atomizing electrode assembly, including a first atomizing electrode, a second atomizing electrode, and a third atomizing electrode respectively electrically connected to the atomizing core, the first atomizing electrode being disposed on the peripheral side wall away from the liquid storage cavity. On one side, the second atomizing electrode and the third atomizing electrode are disposed on the side of the bottom wall away from the liquid storage chamber. The liquid storage chamber is used to insert into the main unit of the aerosol generating device, so that when the liquid storage chamber is inserted into multiple positions in the insertion direction, the first atomizing electrode is conductive to the main unit, and one of the second atomizing electrode and the third atomizing electrode is conductive to the main unit; or the first atomizing electrode, the second atomizing electrode, and the third atomizing electrode are each conductive to the main unit; thereby making the atomizing resistance of the atomizing core different at different positions.

[0013] In one specific embodiment, the atomizing core includes a liquid-absorbing element and a heating element. The liquid-absorbing element is used to generate an aerosol matrix.

In multiple positions; the first main electrode is conductive to the atomizer, and one of the second and third main electrodes is conductive to the atomizer; or the first, second, and third main electrodes are each conductive to the atomizer; thus, the atomization resistance of the atomizer is different in different positions, allowing the atomizer to operate at different output powers while the main unit operates at the same output voltage, resulting in different atomization amounts of aerosol from the aerosol matrix. This increases the atomizer's usage modes. Furthermore, since the output voltage of the main unit does not need to be adjusted, the atomization amount of the aerosol matrix can also be adjusted, allowing the main unit to operate with a stable output voltage. This avoids the risk of damage to the atomizer and main unit due to unstable output voltage, improving safety and lifespan. Attached Figure Description

[0031] Please see Figure 1 , Figure 1 This is a three-dimensional assembly structure diagram of an embodiment of the aerosol generating device 1 provided in this application. The aerosol generating device 1 in this embodiment includes an atomizer 10 and a main unit 20.

[0032] Please refer to the following: Figure 2 and Figure 3 , Figure 2 yes Figure 1 A three-dimensional structural diagram of the atomizer 10. Figure 3 yes Figure 2 A cross-sectional schematic diagram of the atomizer. In this embodiment, the atomizer 10 includes a liquid storage chamber 11, an atomizing core 12, and an atomizing electrode assembly 13.

[0033] The liquid storage chamber 11 includes a bottom wall 11a and a peripheral side wall 11b. The bottom wall 11a and the peripheral side wall 11b are connected to form a liquid storage cavity 110, which is used to store aerosol matrix.

[0034] Specifically, in this embodiment, the liquid storage tank 11 includes a suction nozzle 111 and a tank body 112. The suction nozzle 111 is provided with an air outlet 101. The tank body 112 includes the aforementioned bottom wall 11a and peripheral side wall 11b. The peripheral side wall 11b is connected to the suction nozzle 111 on the side of the suction nozzle 111 away from the air outlet 101.

[0035] Furthermore, the liquid storage tank 11 is also provided with an atomizing air inlet 102, through which external air can enter the liquid storage tank 11. In this embodiment, the atomizing air inlet 102 is provided on the tank body 112.

[0036] Optionally, the liquid storage tank 11 is also provided with an atomizing limiting part 113, which can be an atomizing engaging part or a magnetic limiting part.

[0037] In this embodiment, the atomizer 10 can be a disposable atomizer or a reusable atomizer.

[0038] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 3 A schematic diagram of one embodiment of the heating element 122 shows that the atomizing core 12 is disposed in the liquid storage chamber 110. The atomizing core 12 is used to absorb and heat the aerosol matrix to generate aerosol.

[0039] Specifically, after the atomizing core 12 absorbs and heats the aerosol matrix, the generated aerosol is discharged from the air outlet 101 by the external air entering from the atomizing air inlet 102.

[0040] The atomizing core 12 includes a liquid absorption element 121 and a heating element 122. The liquid absorption element 121 is used to absorb aerosol to generate a matrix. The heating element 122 includes at least three pins 122a and at least two heating elements 122b. The at least three pins 122a are arranged sequentially at intervals. Each of the at least two heating elements 122b is connected to two adjacent pins 122a and is used to heat the aerosol matrix.

[0041] Specifically, at least three pins 122a include a first pin 1221, a second pin 1222 and a third pin 1223, and correspondingly, at least two heating elements 122b include a first heating element 1224 and a second heating element 1225.

[0042] Please refer to the following: Figure 4 and Figure 5 , Figure 5 yes Figure 3 A schematic diagram of another embodiment of the heating element 122.

[0043] Optionally, in such Figure 4In one embodiment shown, the first pin 1221, the second pin 1222, and the third pin 1223 are arranged sequentially at intervals, that is, the first pin 1221, the second pin 1222, and the third pin 1223 are arranged as follows: Figure 4 As shown in the diagram, B is arranged sequentially upwards. The first heating element 1224 is connected to the first pin 1221 and the second pin 1222, respectively, and the second heating element 1225 is connected to the second pin 1222 and the second pin 1223, respectively.

[0044] Optionally, in such Figure 5 In another embodiment shown, the first pin 1221 is disposed between the second pin 1222 and the third pin 1223, then the first heating element 1224 is connected to the second pin 1222 and the first pin 1221 respectively, and the second heating element 1225 is connected to the first pin 1221 and the second pin 1223 respectively.

[0045] Optionally, the spacing between two different pins 122a can be the same or different, and the materials used to fabricate the heating element 122b between two different pins 122a can be the same or different.

[0046] For example, with Figure 5 For example, when the distance L1 between the second pin 1222 and the first pin 1221 is the same as the distance L2 between the first pin 1221 and the third pin 1223, and the first heating element 1224 and the second heating element 1225 are made of the same material, then the resistance values ​​of the first heating element 1224 and the second heating element 1225 can be made the same. When the materials used to manufacture the heating element 1225 are different, the resistance values ​​of the first heating element 1224 and the second heating element 1225 can be different. When the distance L1 between the second pin 1222 and the first pin 1221 is different from the distance L2 between the first pin 1221 and the third pin 1223, and the materials used to manufacture the first heating element 1224 and the second heating element 1225 are the same, the resistance values ​​of the first heating element 1224 and the second heating element 1225 can also be different. The specific method can be set according to actual needs and is not limited in this regard.

[0047] It is understood that although this embodiment uses three pins 122a and two heating elements 22b as an example for explanation, other embodiments may use other numbers of pins and heating elements, such as four pins 122a and three heating elements 122b, which is also within the scope of this embodiment.

[0048] Optionally, the atomizing core 12 in this embodiment also includes an atomizing tube 123, which is disposed in the liquid storage chamber 11 and has a liquid inlet 103. The liquid suction element 121 is disposed in the atomizing tube 123 and absorbs the aerosol matrix through the liquid inlet 103.

[0049] Further reading Figure 2 The atomizing electrode assembly 13 includes a first atomizing electrode 131, a second atomizing electrode 132, and a third atomizing electrode 133, which are electrically connected to the atomizing core 12. The first atomizing electrode 131 is disposed on the side of the peripheral sidewall 11b away from the liquid storage cavity 110, and the second atomizing electrode 132 and the third atomizing electrode 133 are disposed on the side of the bottom wall 11a away from the liquid storage cavity 110.

[0050] The liquid storage tank 11 is inserted into the main unit 20 of the aerosol generating device 1, such that the liquid storage tank 11 is in the insertion direction, i.e., as shown in the figure. Figure 1 When A is inserted into multiple positions upwards, the first atomizing electrode 131 is conductive to the main unit 20, and one of the second atomizing electrode 132 and the third atomizing electrode 133 is conductive to the main unit 20; or the first atomizing electrode 131, the second atomizing electrode 132, and the third atomizing electrode 133 are conductive to the main unit 20 respectively. This results in different atomization resistances of the atomizing core 12 at different positions. Consequently, when the main unit 20 operates at the same output voltage, the atomizing core 12 operates at different output powers, causing the aerosol matrix to produce aerosols of different atomization amounts. This increases the usage modes of the atomizer 10. At the same time, since it is not necessary to adjust the output voltage of the main unit 20, the atomization amount of the aerosol matrix can also be adjusted, allowing the main unit 20 to operate with a stable output voltage. This avoids the risk of damage to the atomizer 10 and the main unit 20 due to unstable output voltage of the main unit 20, thus improving safety and service life.

[0051] Specifically, the first pin 1221 is electrically connected to the first atomizing electrode 131, the second pin 1222 is electrically connected to the second atomizing electrode 132, and the third pin 1223 is electrically connected to the third atomizing electrode 133.

[0052] For example, Figure 2 and Figure 4As shown, when the liquid storage tank 11 is inserted into the first position in the insertion direction, the first atomizing electrode 131 is conductive to the main unit 20, and the second atomizing electrode 132 is conductive to the main unit 20, while the third atomizing electrode 133 is non-conductive to the main unit 30, or the second atomizing electrode 132 is non-conductive to the main unit 20, while the third atomizing electrode 133 is conductive to the main unit 30. At this time, when the main unit 20 is powered, only the first heating element 1224 can work, or the first heating element 1224 and the second heating element 1225 work in series. Therefore, in the first position, the atomization resistance of the atomizing core 12 is the resistance of the first heating element 1224 or the total series resistance of the first heating element 1224 and the second heating element 1225.

[0053] For example, Figure 5 As shown, when the liquid storage tank 11 is inserted into the first position in the insertion direction, the first atomizing electrode 131 is conductive to the main unit 20, and the second atomizing electrode 132 is conductive to the main unit 20, while the third atomizing electrode 133 is non-conductive to the main unit 30, or the second atomizing electrode 132 is non-conductive to the main unit 20, while the third atomizing electrode 133 is conductive to the main unit 30. At this time, when the main unit 20 is powered, only the first heating element 1224 or only the second heating element 1225 can work. Therefore, in the first position, the atomization resistance of the atomizing core 12 is the resistance of the first heating element 1224 or the resistance of the second heating element 1225.

[0054] like Figure 4 or Figure 5 As shown, when the liquid storage tank 11 is inserted into the second position in the insertion direction, the first atomizing electrode 131 is conductive to the main unit 20, the second atomizing electrode 132 is conductive to the main unit 20, and the third atomizing electrode 133 is conductive to the main unit 30. At this time, when the main unit 20 is powered, the first heating element 1224 and the second heating element 1225 work in parallel. Then, in the second position, the atomization resistance of the atomizing core 12 is the total parallel resistance of the first heating element 1224 and the second heating element 1225. Since the total parallel resistance is less than the resistance of the first heating element 1224 or the total series resistance, the atomization resistance of the atomizing core 12 can be different when the liquid storage tank 11 is in the first position and the second position.

[0055] Furthermore, in this embodiment, the first atomizing electrode 131 is also used to be in a conductive state with the main unit 20, and the second atomizing electrode 132 and the third atomizing electrode 133 are also used to be disconnected from the main unit 20 respectively, so that when the liquid storage tank 11 is in this position, only the first atomizing electrode 131 is in a conductive state with the main unit 20, thereby preventing the atomizer 10 from working. This setting can prevent children from accidentally operating the atomizer 10 when it is not needed, and can play a child lock role.

[0056] Please see Figure 6 , Figure 6 yes Figure 1 A three-dimensional structural diagram of the host 20 embodiment is shown. In this embodiment, the host 20 includes a host body 21 and a host electrode assembly 22.

[0057] Please refer to the following: Figure 7 and Figure 8 , Figure 7 yes Figure 6 A cross-sectional schematic diagram of the main unit 21. Figure 8 yes Figure 7 A cross-sectional schematic diagram of the housing 2111 shows that the main body 21 has a receiving cavity 201. The main body 21 includes a housing assembly 211 and a power supply 212. The housing assembly 211 has a receiving cavity 201 for inserting the atomizer 10 of the aerosol generating device 1. In this embodiment, it is also used for inserting the liquid storage tank 11 mentioned above.

[0058] Specifically, in this embodiment, the housing assembly 211 includes a housing 2111 and a bracket 2112. The housing 2111 forms an installation space 202. The bracket 2112 is disposed in the installation space 202 and cooperates with the housing 2111 to form the aforementioned receiving cavity 201. The bracket 2112 is provided with a power supply compartment 203, and the power supply 212 is disposed in the power supply compartment 203.

[0059] Further reading Figure 6 and Figure 7 The host electrode assembly 22 includes a first host electrode 221, a second host electrode 222, and a third host electrode 223. The first host electrode 221 is disposed on the side of the housing 2111 near the receiving cavity 201. The first host electrode 221 is strip-shaped and faces the opening direction of the receiving cavity 201, i.e., as shown in the figure. Figure 7 As shown, C extends upwards, and the second host electrode 222 and the third host electrode 223 are disposed on the bracket 2112. In this embodiment, the first host electrode 221, the second host electrode 222 and the third host electrode 223 are electrically connected to the power supply 212 respectively.

[0060] Furthermore, the second host electrode 222 and the third host electrode 223 are in the opening direction of the accommodating cavity 201, that is, as shown in... Figure 7 The different installation heights (C-direction) allow the atomizer 10 to be inserted into multiple positions in the opening direction of the accommodating cavity 201. This results in the first main electrode 221 being conductive to the atomizer 10, and one of the second main electrode 222 and the third main electrode 223 being conductive to the atomizer 10. Alternatively, the first main electrode 221, the second main electrode 222, and the third main electrode 223 may be conductive to the atomizer 10, resulting in different atomization resistances at different positions. This allows the atomizer 10 to operate with different output powers while the main unit 21 operates at the same output voltage, producing aerosols with varying atomization amounts. This increases the usage modes of the atomizer 10. Furthermore, since the output voltage of the main unit 21 does not need to be adjusted, the atomization amount of the aerosol matrix can be adjusted, ensuring the main unit 21 operates with a stable output voltage. This avoids the risk of damage to the atomizer 10 and the main unit 20 due to unstable output voltage, improving safety and lifespan.

[0061] Specifically, in this embodiment, taking the installation height of the second host electrode 222 in the opening direction of the accommodating cavity 201 as greater than the installation height of the third host electrode 223 in the opening direction of the accommodating cavity as an example, wherein the second host electrode 222 is telescopically configurable relative to the bracket.

[0062] See also Figure 2 , Figure 4 , Figure 9 , Figure 10 and Figure 11 , Figure 9 yes Figure 2 A schematic diagram of the atomizer 10 in its first position. Figure 10 yes Figure 9 An enlarged schematic diagram of section M in the middle. Figure 11 yes Figure 2 A schematic diagram of the atomizer 10 in the second position. When the atomizer 10 is inserted into the first position in the insertion direction A, the first main electrode 221 and the first atomizing electrode 131 are in a conductive state, and as shown... Figure 9 and Figure 10As shown, the second main electrode 222 is in contact with the second atomizing electrode 132 and is in a conductive state. At this time, since the installation height of the third main electrode 223 in the opening direction is less than the installation height of the second main electrode 222, the third main electrode 223 cannot contact the third atomizing electrode 133 and is in a non-conductive state. Therefore, in the first position, the atomization resistance of the atomizer 10 is the resistance of the first heating element 1224. Since the first main electrode 221 is strip-shaped, the first main electrode 221 and the first atomizing electrode 131 can continuously be in a conductive state during insertion. Therefore, when the atomizer 10 is inserted into the second position in the insertion direction A, the first main electrode 221 and the first atomizing electrode 131 are in a conductive state, and as shown... Figure 11 As shown, the second main electrode 222 is in contact with the second atomizing electrode 132 and is in a conductive state, and the third main electrode 223 is in contact with the third atomizing electrode 133 and is in a conductive state. Therefore, in the second position, the atomization resistance of the atomizer 10 is the parallel total resistance of the first heating element 1224 and the second heating element 1225. This parallel total resistance is different from the resistance of the first heating element 1224, so that the atomization resistance of the atomizer 10 is different in different positions.

[0063] The first host electrode 221 and the second host electrode 222 have opposite polarities.

[0064] Furthermore, the main body 21 is provided with a mounting groove 204, and the second main electrode 222 is disposed in the mounting groove 204. An elastic element 23 is provided in the mounting groove 204, and the elastic element 23 abuts against the bracket 2112 and the second main electrode 222 respectively. When the atomizer 10 is subjected to external force... Figure 9 The first position shown is inserted as follows: Figure 11 In the second position shown, the second host electrode 222 compresses the elastic element 23. When the external force disappears, the second host electrode 222 resets under the elastic force of the elastic element 23.

[0065] Further reading Figure 6 The housing 2111 has a plurality of main unit limiting parts 24 on the side near the receiving cavity 201. The plurality of main unit limiting parts 24 are arranged sequentially along the opening direction of the receiving cavity 201. Each main unit limiting part 24 is used to limit the atomizer 10 at each position. For example, the plurality of main unit limiting parts 24 include main unit limiting part 24a and main unit limiting part 24b. When the atomizer 10 is located in the first position mentioned above, the main unit limiting part 24a limits the atomizer 10. When the atomizer 10 is located in the second position mentioned above, the main unit limiting part 24b limits the atomizer 10.

[0066] Optionally, the main unit limiting part 24 is a main unit engaging part, which is used to engage with the atomizer 10. In this case, the aforementioned atomizing limiting part 113 is also an engaging part, and the two engage with each other, thereby realizing the engagement of the main unit 20 and the atomizer 10.

[0067] Optionally, the main unit limiting part 24 is a magnetic limiting part, which is used to adsorb the atomizer 10. In this case, the atomization limiting part 113 mentioned above is also a magnetic limiting part, and the two adsorb each other, thereby realizing the adsorption of the main unit 20 and the atomizer 10.

[0068] Unlike existing technologies, the main unit for an aerosol generating device provided in this application includes: a main unit body, comprising a housing and a support, wherein the housing forms an installation space, the support is disposed within the installation space and cooperates with the housing to form a receiving cavity, the receiving cavity being used to insert the atomizer of the aerosol generating device; and a main unit electrode assembly, comprising a first main unit electrode, a second main unit electrode, and a third main unit electrode, wherein the first main unit electrode is disposed on the side of the housing near the receiving cavity, the first main unit electrode is strip-shaped and extends in the opening direction of the receiving cavity, the second main unit electrode and the third main unit electrode are disposed on the support, and the second main unit electrode and the third main unit electrode are installed at different heights in the opening direction of the receiving cavity, so that when the atomizer is inserted into multiple positions in the receiving cavity in the opening direction. The first main electrode is conductive to the atomizer, and one of the second and third main electrodes is conductive to the atomizer; or the first, second, and third main electrodes are each conductive to the atomizer. This results in different atomization resistances at different locations of the atomizer, allowing the atomizer to operate at different output powers while the main unit operates at the same output voltage. This results in different atomization amounts of aerosol from the aerosol matrix, increasing the atomizer's usage modes. Furthermore, since the main unit's output voltage does not need to be adjusted, the atomization amount of the aerosol matrix can be adjusted, enabling the main unit to operate with a stable output voltage. This avoids the risk of damage to the atomizer and main unit due to unstable output voltage, improving safety and lifespan.

Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the scope of patent protection of this application.
