[0001] This application relates to the field of aerosol generating device technology, specifically to an atomizer, a main unit, and an aerosol generating device. Background Technology

[0002] The aerosol generating device supplies power to the atomizer via the main unit, thereby heating the aerosol matrix and generating aerosol.

[0003] In existing technologies, atomizers can generally only operate at one output power, which means that the atomizer can only produce the same amount of aerosol, resulting in a relatively limited mode. Summary of the Invention

[0004] This application mainly provides an atomizer, a main unit, and an aerosol generating device, which increases the usage modes of the atomizer, avoids the risk of damage to the atomizer and main unit due to unstable output voltage of the main unit, and improves safety and service life.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a main unit for an aerosol generating device, the main unit comprising: a main unit body, the main unit body forming a receiving cavity for inserting an atomizer of the aerosol generating device; an electromagnet disposed on the side of the main unit body facing the opening direction of the receiving cavity; and a main unit electrode assembly including a first main unit electrode and at least two second main unit electrodes, the first main unit electrode and at least two second main unit electrodes being mounted in the main unit body, and the at least two second main unit electrodes having different heights in the opening direction of the receiving cavity; wherein, the electromagnet is used to generate different magnetic forces to drive the atomizer to move to multiple positions respectively, the first main unit electrode being conductive with the atomizer at each of the multiple positions, and the atomizer being conductive with different numbers of second main unit electrodes at different positions, thereby causing the atomization resistance of the atomizer to be different at different positions.

[0006] In one specific embodiment, the host body includes a housing assembly and a power supply assembly. The housing assembly forms the receiving cavity, and the power supply assembly is electrically connected to the electromagnet to supply power to the electromagnet.

[0007] In one specific embodiment, the power supply assembly includes a power supply and a control circuit board. The power supply is electrically connected to the electromagnet, and the control circuit board is electrically connected to the power supply to send a power supply command to the power supply.

[0008] In one specific embodiment, the housing assembly is provided with a toggle mechanism, which is electrically connected to the power supply assembly so that the power supply assembly adjusts the magnitude or direction of the supplied current according to the toggle position of the toggle mechanism.

[0009] In one specific embodiment, the actuating mechanism is provided with a first resistance mark, and the housing assembly is provided with a plurality of second resistance marks.

[0010] In one specific embodiment, the first host electrode and at least two second host electrodes are disposed on the side of the host body facing the opening direction, and the first host electrode and at least one of the at least two second host electrodes are retractably disposed relative to the host body.

[0011] In one specific embodiment, the electromagnet is also used to drive the atomizer to a position where the first host electrode is no longer in a conductive state from 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 for storing an aerosol matrix, the liquid storage chamber being provided with an adsorption element; an atomizing core disposed within the chamber, the atomizing core being used to absorb and heat the aerosol matrix to generate aerosol; and an atomizing electrode assembly comprising a first atomizing electrode and at least two second atomizing electrodes, the first atomizing electrode and at least two second atomizing electrodes being mounted on the liquid storage chamber and electrically connected to the atomizing core respectively, the liquid storage chamber being inserted into the main unit of the aerosol generating device, such that when the adsorption element, under the magnetic force of the main unit, moves the liquid storage chamber to multiple positions, the first atomizing electrode is electrically conductive with the main unit at multiple positions, and the main unit is electrically conductive with different numbers of second atomizing electrodes at different positions, thereby causing the atomization resistance of the atomizer to be 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. The heating element includes at least three pins and at least two heating elements. The at least three pins are arranged sequentially at intervals. Each of the at least two heating elements is connected to two adjacent pins and is used to heat the aerosol matrix. The at least three pins include a first pin and at least two second pins. The first pin is electrically connected to the first atomizing electrode, and each of the at least two second pins is electrically connected to each of the at least two second atomizing electrodes.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide an aerosol generating device, which includes the above-mentioned main unit and the above-mentioned atomizer.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, the main unit for an aerosol generating device provided in this application includes: a main unit body, the main unit body forming a receiving cavity for inserting an atomizer of the aerosol generating device; an electromagnet disposed on the side of the main unit body facing the opening direction of the receiving cavity; and a main unit electrode assembly including a first main unit electrode and at least two second main unit electrodes, the first main unit electrode and at least two second main unit electrodes being mounted in the main unit body, and the at least two second main unit electrodes having different heights in the opening direction of the receiving cavity; wherein, the electromagnet is used to generate different magnetic forces to drive the atomizer to move to multiple positions respectively, the first main unit electrode... The electrodes are respectively in a conductive state with the atomizer at multiple locations, and the atomizer is in a conductive state with a different number of second main unit electrodes at different locations. This results in different atomization resistances of the atomizer at different locations, allowing the atomizer to operate with different output powers when the main unit operates at the same output voltage. This causes the aerosol matrix to produce different amounts of aerosol, increasing the atomizer's usage modes. At the same time, since the atomization amount of the aerosol matrix can be adjusted without adjusting the main unit's output voltage, the main unit can operate with a stable output voltage, avoiding the risk of damage to the atomizer and main unit due to unstable main unit output voltage, thus improving safety and service life.

[0032] 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.

[0033] 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.

[0034] The liquid storage chamber 11 is used to store the aerosol matrix.

[0035] Specifically, the liquid storage chamber 11 includes a suction nozzle 111 and a chamber body 112. The suction nozzle 111 is provided with an air outlet 101. The chamber body 112 is used to store the aerosol matrix and is connected to the suction nozzle 111 on the side of the suction nozzle 111 away from the air outlet 101.

[0036] 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.

[0037] Optionally, the liquid storage tank 11 is also provided with an adsorption element 113. In this embodiment, the adsorption element 113 is located on the side of the tank body 112 away from the air outlet 101. In practical applications, the adsorption element 113 can be a magnetic adsorption element, such as a magnet or an electromagnet.

[0038] Optionally, the liquid storage tank 11 also has an injection port (not shown in the figure), through which an aerosol matrix can be injected into the liquid storage tank 11. In this embodiment, the tank body 112 is provided with the injection port.

[0039] In this embodiment, the atomizer 10 also includes a liquid injection plug 14, which is connected to the liquid storage chamber 11 to open or close the liquid injection port. That is, when it is necessary to inject aerosol matrix into the liquid storage chamber 11, the liquid injection plug 14 opens the liquid injection port, and after the injection is completed, the liquid injection plug 14 closes the liquid injection port, so that the atomizer 10 in this embodiment can be reused multiple times. Of course, in other embodiments, the liquid injection port and the liquid injection plug 14 may not be provided. In this case, the atomizer 10 is a disposable atomizer.

[0040] 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 11 and is used to absorb and heat the aerosol matrix to generate aerosol.

[0041] Specifically, the atomizing core 12 is installed inside the chamber 112. After the atomizing core 12 absorbs and heats the aerosol matrix, the generated aerosol is discharged from the air outlet 101 through the external air entering from the atomizing air inlet 102.

[0042] 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.

[0043] Among them, at least three pins 122a include a first pin 1221 and at least two second pins. For example, in this embodiment, three pins 122a are the first pin 1221 and two second pins, which are the second pins 1222 and 1223. Correspondingly, there are two heating elements 122b, which are the first heating element 1224 and the second heating element 1225.

[0044] 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.

[0045] Optionally, in such Figure 4 In one embodiment shown, the first pin 1221 and at least two second pins are arranged sequentially at intervals, that is, the first pin 1221 and at least two second pins are arranged as follows: Figure 4 As shown, pins B are arranged sequentially upwards. For example, taking three pins 122a as an example, the first pin 1221 is located to the left of the second pin 1222, and the second pins 1222 and 1223 are arranged sequentially to the right of the first pin 1221. Then, 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.

[0046] Optionally, in such Figure 5 In another embodiment shown, the first pin 1221 is disposed between two adjacent second pins. For example, taking three pins 122a as an example, the first pin 1221 is disposed between the second pins 1222 and 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.

[0047] 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.

[0048] For example, with Figure 5For 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 second pin 1223, and the first heating element 1224 and the second heating element 1225 are made of the same material, then the resistance 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 second 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.

[0049] 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.

[0050] 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.

[0051] Further reading Figure 2 The atomizing electrode assembly 13 includes a first atomizing electrode 131 and at least two second atomizing electrodes 131a. The first atomizing electrode 131 and at least two second atomizing electrodes 131a are mounted on the liquid storage chamber 11 and are electrically connected to the atomizing core 12 respectively. In this embodiment, the first atomizing electrode 131 and at least two second atomizing electrodes 131a are disposed on the side of the liquid storage chamber 11 away from the air outlet 101.

[0052] The liquid storage chamber 11 is inserted into the main unit 20 of the aerosol generating device 1. When the adsorption element 113 moves the liquid storage chamber 11 to multiple positions under the magnetic force of the main unit 20, the first atomizing electrode 131 is conductive with the main unit 20 at these positions. The main unit 20 is conductive with different numbers of second atomizing electrodes 131a at different positions, resulting in different atomization resistances of the atomizing core 12 at different positions. This allows the atomizing core 12 to operate with different output powers while the main unit 20 operates at the same output voltage, generating different amounts of aerosol from the aerosol matrix. This increases the usage modes of the atomizer 10. Furthermore, since the output voltage of the main unit 20 does not need to be adjusted, the atomization amount of the aerosol matrix can 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, improving safety and service life. In this embodiment, the liquid storage chamber 11 moves along the magnetic force of the main unit 20... Figure 1 The motion in direction A is shown.

[0053] Specifically, the first pin 1221 is electrically connected to the first atomizing electrode 131, and each of the at least two second pins is electrically connected to each of the at least two second atomizing electrodes 131a. For ease of explanation, in this embodiment, the heating element 122 is... Figure 4 For example, there are two second atomizing electrodes 131a, namely second atomizing electrode 132 and second atomizing electrode 133. Second atomizing electrode 132 is electrically connected to second pin 1222, and second atomizing electrode 133 is electrically connected to second pin 1223.

[0054] For example, Figure 2 and Figure 4As shown, when the liquid storage tank 11 moves to the first position under the magnetic force of the main unit 20, 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 second atomizing electrode 133 is non-conductive to the main unit 20. At this time, with the main unit 20 powered, only the first heating element 1224 can work. Therefore, at the first position, the atomization resistance of the atomizing core 12 is the resistance of the first heating element 1224. When the liquid storage tank 11 moves to the second position under the magnetic force of the main unit 20, the first atomizing electrode 131 and the main unit 20 are non-conductive. When the atomizing electrode 132 is in a conductive state and the second atomizing electrode 133 is in a conductive state with the main unit 20, and the second atomizing electrode 133 is in a conductive state with the main unit 30, the first heating element 1224 and the second heating element 1225 operate in parallel when powered by the main unit 20. In the second position, the atomizing 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, the atomizing resistance of the atomizing core 12 is different when the liquid storage tank 11 is in the first position and the second position.

[0055] Optionally, at least two second atomizing electrodes 131a have the same polarity and are opposite to the polarity of the first atomizing electrode 131. For example, the first atomizing electrode 131 is a positive electrode, and the second atomizing electrodes 132 and 133 are both negative electrodes.

[0056] Furthermore, in this embodiment, the first atomizing electrode 131 is also used to move the liquid storage tank 11 to a position where the first atomizing electrode 131 and the main unit 20 are in a conductive state and at least two second atomizing electrodes 131a are respectively out of the conductive state from the main unit 20, or the first atomizing electrode 131 and the main unit 20 are out of the conductive state. This ensures that when the liquid storage tank 11 is in this position, only the first atomizing electrode 131 and the main unit 20 are in a conductive state, or the first atomizing electrode 131 and at least two second atomizing electrodes 131a are both out of the conductive state from 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, thus serving as a child lock.

[0057] 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, an electromagnet 20a, and a host electrode assembly 22.

[0058] Please refer to the following: Figure 7 and Figure 8 , Figure 7 yes Figure 6A 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 assembly 212. The housing assembly 211 has a receiving cavity 201.

[0059] Specifically, in this embodiment, the housing assembly 211 includes a housing 2111 and a bracket 2112. The housing 2111 forms an installation space 202, and the bracket 2112 is disposed in the installation space 202 to form the aforementioned accommodating cavity 201. The bracket 2112 is provided with a power compartment 203, and the power assembly 212 is disposed in the power compartment 203.

[0060] The power supply assembly 212 includes a power supply 2121 and a control circuit board 2122. The control circuit board 2122 is electrically connected to the power supply 2121 to send a power supply command to the power supply 2121.

[0061] The electromagnet 20a is disposed on the side of the main body 21 facing the opening of the accommodating cavity 201. In this embodiment, it is disposed on the side of the bracket 2112 near the accommodating cavity 201.

[0062] In this embodiment, the electromagnet 20a is electrically connected to the power supply component 212 so that the power supply component 212 supplies power to the magnet, thereby generating magnetic force. In this embodiment, the electromagnet 20a is also electrically connected to the power supply 2121.

[0063] Further reading Figure 6 and Figure 7 The host electrode assembly 22 includes a first host electrode 221 and at least two second host electrodes 222. The first host electrode 221 and at least two second host electrodes 222 are installed inside the host body 21. In this embodiment, the first host electrode 221 and at least two second host electrodes 222 are electrically connected to the power supply 2121.

[0064] Furthermore, the accommodating cavity 201 is used to insert the atomizer 10 of the aerosol generating device 1. In this embodiment, it is also used to insert the aforementioned liquid storage tank 11. At least two second host electrodes 222 are in the opening direction of the accommodating cavity 201, i.e., as shown... Figure 7As shown, the installation heights upwards (C-axis) are different, and the electromagnet 20a is used to generate different magnetic forces. This allows the atomizer 10 to be inserted into multiple positions in the opening direction of the accommodating cavity 201. The first main electrode 221 is conductive with the atomizer 10 at multiple positions, and the atomizer 10 is conductive with different numbers of second main electrodes 222 at different positions. This results in different atomization resistances of the atomizer 10 at different positions. Consequently, while the main unit 21 operates at the same output voltage, the atomizer 10 operates with different output powers, resulting in different atomization amounts of aerosol from the aerosol matrix. 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 also be adjusted, allowing the main unit 21 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, thus improving safety and service life.

[0065] The first host electrode 221 and at least two second host electrodes 222 are disposed on the side of the host body 21 facing the opening direction. In this embodiment, they are disposed on the side of the bracket 2112 near the receiving cavity 201, and the first host electrode 221 and at least one of the at least two second host electrodes 222 are retractable relative to the host body 21.

[0066] For example, at least two second host electrodes 222 include a first sub-electrode 2221 and a second sub-electrode 2222. The installation height of the first sub-electrode 2221 in the opening direction is greater than the installation height of the second sub-electrode in the opening direction. The first host electrode 221 and the first sub-electrode 2222 are retractable relative to the host body 21.

[0067] 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 adsorption element 113 on the atomizer 10 moves to the first position under the magnetic force of the electromagnet 20a, as shown... Figure 9 and Figure 10As shown, the first main electrode 221 is in contact with the first atomizing electrode 131 and is in a conductive state, and the first sub-electrode 2221 is in contact with the second atomizing electrode 132 and is in a conductive state. At this time, since the installation height of the second sub-electrode 2222 in the opening direction is less than the installation height of the first sub-electrode 2221, the second sub-electrode 2222 cannot contact the second 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. When the adsorption element 113 on the atomizer 10 moves to the second position under the magnetic force of the electromagnet 20a, as... Figure 11 As shown, the first main electrode 221 is in contact with the first atomizing electrode 131 and is in a conductive state, and the first sub-electrode 2221 is in contact with the second atomizing electrode 132 and is in a conductive state, and the second sub-electrode 2222 is in contact with the second 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.

[0068] The first host electrode 221 has opposite polarities to the first sub-electrode 2221.

[0069] Furthermore, the main body 21 is provided with a mounting groove 204, and the first main electrode 221 and the first sub-electrode 2221 are disposed in the mounting groove 204. The mounting groove 204 is provided with a first elastic member 23 and a second elastic member 24. The first elastic member 23 abuts against the main body 21 and the first main electrode 221 respectively, and the second elastic member 24 abuts against the main body 221 and the first sub-electrode 2221 respectively. When the adsorption member 113 on the atomizer 10 is pulled away by the magnetic force of the electromagnet 20a, Figure 9 The first position shown moves to, as Figure 11 When the second "first" is as shown, the first host electrode 221 compresses the first elastic element 23, and the first sub-electrode 2221 compresses the second elastic element 24. When the magnetic force disappears, the first host electrode 221 resets under the elastic force of the first elastic element 23, and the first sub-electrode 2221 resets under the elastic force of the second elastic element 24.

[0070] Please refer to the following: Figure 9 and Figure 12 , Figure 12 yes Figure 9 A schematic diagram of another embodiment of the first host electrode 221, wherein, as shown in the diagram... Figure 9 In one embodiment shown, the mounting height of the first host electrode 221 in the opening direction of the accommodating cavity 201 is the same as the mounting height of the first sub-electrode 2221 in the opening direction. Figure 12In another embodiment shown, the mounting height of the first host electrode 221 in the opening direction is greater than the mounting height of the first sub-electrode 2221 in the opening direction.

[0071] Among them, the electromagnet 20a is also used to drive the atomizer 10 to move to the position where the first main electrode 221 is no longer in a conductive state from the atomizer 10, or the first main electrode 221 is in a conductive state from the atomizer 10, and the first sub-electrode 2221 is no longer in a conductive state from the atomizer 10. At this time, the atomizer 10 is in an inedible state.

[0072] Specifically, when the adsorption element 113 on the atomizer 10 moves to the aforementioned position under the magnetic force of the electromagnet 20a, if the first main electrode 221 is in a conductive state with the atomizer 10 and the first sub-electrode 2221 is out of the conductive state with the atomizer 10, since the installation height of the first sub-electrode 2221 and the second sub-electrode 2222 is less than that of the first main electrode 221, then at this position, the atomizer 10 is in an unusable state, preventing accidental operation by children when not in use, thus acting as a child lock. Similarly, when the first sub-electrode 2221 is out of the conductive state with the atomizer 10, the atomizer 10 is also in an unusable state.

[0073] Understandably, in this embodiment, the housing 2111 is rectangular and the accommodating cavity 201 has a rectangular cross-section in the opening direction. In other embodiments, the housing 2111 and the accommodating cavity 201 may also be other shapes, such as the housing 2111 being cylindrical and the accommodating cavity 201 having a circular cross-section in the opening direction.

[0074] Further reading Figure 6 The housing assembly 211 is also provided with a toggle mechanism 21a, which is electrically connected to the power supply assembly 212. This allows the power supply assembly 212 to adjust the magnitude or direction of the supplied current according to the toggle position of the toggle mechanism 21a. In this embodiment, the toggle mechanism 21a is electrically connected to the control circuit board 2122, allowing the control circuit board 2122 to send different power supply commands to the power supply 2121 according to the toggle position of the toggle mechanism 21a. This causes the power supply 2121 to adjust the magnitude or direction of the supplied current. For example, when the toggle mechanism 21a is in a certain position... Figure 6 When C1 is toggled upwards, the power supply assembly 212 supplies power to the electromagnet 20a, generating a magnetic force that attracts the suction element 113 on the atomizer 10, bringing the atomizing electrode assembly 13 closer to the main unit electrode assembly 22. Simultaneously, when the power supply assembly 212 supplies power, different currents generate different magnetic forces, allowing the atomizer to be attracted to different positions. When the toggle mechanism 21a is in the position shown... Figure 6When C2 is flipped upwards, the power supply component 212 supplies power to the electromagnet 20a, changing the direction of the current so that the magnetic force generated by the electromagnet 20a becomes a repulsive force. This repulsive force repels the adsorption component 113 on the atomizer 10, causing the atomizing electrode component 13 to move away from the main electrode component 22 and thus move to different positions.

[0075] The atomizer 21a is provided with a first resistance mark 21b, and the housing assembly 211 is provided with multiple second resistance marks 21c. This allows the user to adjust the atomizer 21a according to the actual amount of atomization required. When different second resistance marks 21c are aligned with the first resistance mark 21b, the electromagnet 20a generates different magnetic forces, which allows the atomizer 10 to move to different positions. This allows the atomizer 10 to produce aerosols of different amounts or to be in an unusable state, improving the convenience of use for the user.

[0076] Unlike existing technologies, the main unit for an aerosol generating device provided in this application includes: a main unit body with a receiving cavity for inserting an atomizer of the aerosol generating device; an electromagnet disposed on the side of the main unit body facing the opening of the receiving cavity; and a main unit electrode assembly including a first main unit electrode and at least two second main unit electrodes, the first main unit electrode and at least two second main unit electrodes being mounted in the main unit body, and the at least two second main unit electrodes having different heights in the opening direction of the receiving cavity; wherein, the electromagnet is used to generate different magnetic forces to drive the atomizer to move to multiple positions, and the first main unit electrode is respectively at multiple positions. The aforementioned positions are electrically conductive with the atomizer, and the atomizer is electrically conductive with different numbers of second main unit electrodes at different positions. This results in different atomization resistances of the atomizer at different positions, allowing the atomizer to operate with 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 atomization amount of the aerosol matrix can be adjusted without adjusting the main unit's output voltage, the main unit can 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.
