On the electrode support, the atomizing electrode support is movably connected to the liquid storage tank. The liquid storage tank is used to insert into the main unit of the aerosol generating device, so that when the atomizing electrode support moves to multiple positions relative to the liquid storage tank, the first atomizing electrode is conductive to the main unit, and one of the second and third atomizing electrodes is conductive to the main unit; or the first, second, and third atomizing electrodes are each conductive to the main unit; thereby making the atomizing resistance of the atomizing core different at different positions.

[0006] In one specific embodiment, the atomizing core includes a liquid-absorbing element and a heating element. The liquid-absorbing element is used to absorb aerosol to generate a 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.

The first pin is electrically connected to the first atomizing electrode, the second pin is electrically connected to the second atomizing electrode, and the third pin is electrically connected to the third atomizing electrode.

[0007] In one specific embodiment, the first pin, the second pin, or the third pin are arranged sequentially at intervals; or the first pin is arranged between the second pin and the third pin.

[0008] In one specific embodiment, the atomizing electrode support includes a support body and an adjustment body. The support body is movably disposed within the liquid storage chamber. The first atomizing electrode, the second atomizing electrode, and the third atomizing electrode are respectively mounted on the support body. The adjustment body is connected to the support body and exposed outside the liquid storage chamber.

[0009] In one specific embodiment, the adjusting body is slidably connected or rotatably connected to the liquid storage tank.

[0010] In one specific embodiment, the liquid storage chamber is provided with a plurality of first positioning parts, and the atomizing electrode support is provided with a second positioning part, the second positioning part being configured to cooperate with a plurality of first positioning parts at a plurality of the aforementioned positions respectively.

[0011] In one specific embodiment, one of the first positioning part and the second positioning part is a slot, and the other of the first positioning part and the second positioning part is a protrusion, and the slot is used to engage with the protrusion; or one of the first positioning part and the second positioning part is a magnetic positioning part.

[0012] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide an aerosol generating device, the aerosol generating device including a main unit and the atomizer, the main unit forming a receiving cavity, and the liquid storage tank being inserted into the receiving cavity.

[0013] In one specific embodiment, the host includes: a host body having the accommodating cavity; and a host electrode assembly including a first host electrode, a second host electrode, and a third host electrode, wherein the first host electrode, the second host electrode, and the third host electrode are respectively installed in the host body, and the atomizing electrode support moves to multiple positions relative to the liquid storage chamber; the first atomizing electrode is conductive to the first host electrode, and one of the second atomizing electrode and the third atomizing electrode is conductive to one of the second host electrode and the third host electrode; or the first atomizing electrode is conductive to the first host electrode, the second atomizing electrode is conductive to the second host electrode, and the third atomizing electrode is conductive to the third host electrode.

[0014] 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, and the first host electrode and the second host electrode are retractably configured relative to the host body.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, the atomizer for an aerosol generating device provided in this application includes: a liquid storage chamber for storing an aerosol generating matrix; an atomizing core disposed within the liquid storage chamber, the atomizing core absorbing and heating the aerosol generating matrix to generate aerosol; and an atomizing electrode assembly including a first atomizing electrode, a second atomizing electrode, a third atomizing electrode, and an atomizing electrode support. The first, second, and third atomizing electrodes are electrically connected to the atomizing core and respectively mounted on the atomizing electrode support. The atomizing electrode support is movably connected to the liquid storage chamber, which is inserted into the main unit of the aerosol generating device, allowing the atomizing electrode support to move to multiple positions relative to the liquid storage chamber. The first atomizing electrode and the liquid storage chamber are connected to the atomizing core. The main unit is in a conductive state, and one of the second and third atomizing electrodes is conductive to the main unit; or the first, second, and third atomizing electrodes are each conductive to the main unit. This results in different atomization resistances of the atomizing core at different locations, allowing the atomizing core to operate at different output powers while the main unit operates at the same output voltage. This results in the aerosol generating matrix producing different amounts of aerosol, 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 generating 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. Attached Figure Description

[0029] 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.

[0030] Please see Figure 2 , Figure 2 yes Figure 1 A cross-sectional schematic diagram of the atomizer 10. In this embodiment, the atomizer 10 includes a liquid storage chamber 11, an atomizing core 12, and an atomizing electrode assembly 13.

[0031] The liquid storage chamber 11 is used to store the aerosol matrix.

[0032] 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.

[0033] 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.

[0034] Please refer to the following: Figure 2 and Figure 3 , Figure 3 yes Figure 2 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.

[0035] 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.

[0036] 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.

[0037] Among them, at least three pins 122a include a first pin 1221, a second pin 1222 and a third pin 1223, and at least two heating elements 122b include a first heating element 1224 and a second heating element 1225.

[0038] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 2 A schematic diagram of another embodiment of the heating element 122.

[0039] Optionally, in such Figure 3 In one embodiment shown, the first pin 1221, the second pin 1222 and the third pin 1223 are arranged sequentially at intervals, 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 third pin 1223 respectively.

[0040] Optionally, in such Figure 4 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 third pin 1223 respectively.

[0041] 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.

[0042] For example, with Figure 4 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.

[0043] 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.

[0044] 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.

[0045] Further reading Figure 2 The atomizing electrode assembly 13 includes a first atomizing electrode 131, a second atomizing electrode 132, a third atomizing electrode 133, and an atomizing electrode support 134. The first atomizing electrode 131, the second atomizing electrode 132, and the third atomizing electrode 133 are electrically connected to the atomizing core 12 and are respectively mounted on the atomizing electrode support 134. In this embodiment, the first atomizing electrode 131 is electrically connected to the first pin 1221, the second atomizing electrode 132 is electrically connected to the first pin 1222, and the third atomizing electrode 133 is electrically connected to the third pin 1223.

[0046] The atomizing electrode support 134 is movably connected to the liquid storage tank 11.

[0047] Specifically, the atomizing electrode support 134 includes a support body 1341 and an adjusting body 1342. The support body 1341 is movably disposed in the liquid storage chamber 11. The first atomizing electrode 131, the second atomizing electrode 132, and the third atomizing electrode 133 are respectively mounted on the support body 1341. The adjusting body 1342 is connected to the support body 1341 and exposed in the liquid storage chamber 11, so that when the user uses it, the support body 1341 can be moved relative to the liquid storage chamber 11 by adjusting the body 1342, thereby improving the convenience of use for the user.

[0048] The adjusting body 1342 is slidably or rotatably connected to the liquid storage tank 11.

[0049] Please refer to the following: Figure 5 and Figure 6 , Figure 5 yes Figure 1 A cross-sectional schematic diagram of the implementation method of the host computer 20. Figure 6 yes Figure 5 A cross-sectional schematic diagram of the inner shell 2111. In this embodiment, the main unit 20 has a receiving cavity 201, and the aforementioned liquid storage tank 11 is inserted into the receiving cavity 201.

[0050] Specifically, the host 20 includes a host body 21 and a host electrode assembly 22, and the host body 21 forms the aforementioned accommodating cavity 201.

[0051] The main body 21 includes a housing assembly 211 and a power supply 212, and the housing assembly 211 forms a receiving cavity 201.

[0052] Specifically, in this embodiment, the housing assembly 211 includes a housing 2111 and a power support 2112. The housing 2111 forms an installation space 202, and the power support 2112 is disposed in the installation space 202 to form the aforementioned accommodating cavity 201. The power support 2112 is provided with a power compartment 203, and the power supply 212 is disposed in the power compartment 203.

[0053] 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, the second host electrode 222, and the third host electrode 223 are respectively installed inside the host body 21. In this embodiment, the first host electrode 221, the second host electrode 222, and the third host electrode 223 are respectively installed on the power supply bracket 2112 and electrically connected to the power supply 212.

[0054] Furthermore, the liquid storage tank 11 is used to insert into the main unit 20 of the aerosol generating device 1, so that when the atomizing electrode support 134 moves to multiple positions relative to the liquid storage tank 11, 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 each conductive to the main unit 20; thereby making the atomizing resistance of the atomizing core 12 different at different positions. Furthermore, when the main unit 20 operates at the same output voltage, the atomizing core 12 can operate at different output powers, resulting in different atomization amounts of aerosol generated by the aerosol generating matrix. 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 generating 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, thereby improving safety and service life.

[0055] Specifically, when the atomizing electrode support 134 moves to multiple positions relative to the liquid storage chamber 11, the first atomizing electrode 131 and the first main electrode 221 are in a conductive state, and one of the second atomizing electrode 132 and the third atomizing electrode 133 is in a conductive state with one of the second main electrode 222 and the third main electrode 223; or the first atomizing electrode 131 and the first main electrode 221 are in a conductive state, the second atomizing electrode 132 and the second main electrode 222 are in a conductive state, and the third atomizing electrode 133 and the third main electrode 223 are in a conductive state, thereby making the atomizing resistance of the atomizing core 12 different at different positions.

[0056] Furthermore, the second host electrode 222 and the third host electrode 223 are installed at different heights in the opening direction A of the accommodating cavity 201.

[0057] In this embodiment, the installation height of the second host electrode 222 is greater than that of the third host electrode 223. The first host electrode 221 and the second host electrode 222 are telescopically configurable relative to the host electrode bracket 224.

[0058] Please refer to the following: Figure 3 , Figure 7 , Figure 8 and Figure 9 , Figure 7 yes Figure 2 A schematic diagram of the atomizing electrode holder 134 in its first position. Figure 8 yes Figure 7 An enlarged schematic diagram of section M in the middle. Figure 9 yes Figure 2A schematic diagram of the intermediate atomizing electrode holder 134 in the second position. When the adjusting body 1342 slides relative to the holder body 1341, it drives the holder body 1341 to move to the position shown. Figure 7 In the first position shown, the first main electrode 221 is in contact with the first atomizing electrode 131 and is conductive, and the second main electrode 222 is in contact with the second atomizing electrode 132 and is conductive. At this time, because 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 second atomizing electrode 133 and is non-conductive. Therefore, in the first position, the atomization resistance of the atomizing core 12 is the resistance of the first heating element 1134. When the adjusting body 1342 slides relative to the support body 1341, it drives the support body 1341 to move to the position shown. Figure 9 In the second position shown, the first main electrode 221 is in contact with the first atomizing electrode 131 and is in a conductive state, 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 second atomizing electrode 133 and is in a conductive state. In the second position, the atomization resistance of the atomizing core 12 is the parallel total resistance of the first heating element 1134 and the second heating element 1225. This parallel total resistance is different from the resistance of the first heating element 1134, so that the atomization resistance of the atomizing core 12 is different in different positions.

[0059] Furthermore, the main body 21 is provided with a mounting groove 204, in which the first main electrode 221 and the second main electrode 222 are disposed. The mounting groove 204 is provided with a first elastic element 23 and a second elastic element 24. The first elastic element 23 abuts against the main body 21 and the first main electrode 221, respectively, and the second elastic element 24 abuts against the main body 221 and the second main electrode 222, respectively. When the atomizing electrode holder 134 moves from... Figure 7 The first position shown is active as follows Figure 9 In the second position shown, the first main electrode 221 compresses the first elastic element 23, and the second main electrode 222 compresses the second elastic element 24, when the atomizing electrode holder 134 moves from... Figure 9 The second position shown is active as follows Figure 7 In the first position shown, the first host electrode 221 is reset under the elastic force of the first elastic member 23, and the second host electrode 222 is reset under the elastic force of the second elastic member 24.

[0060] It is understandable that the above description uses the sliding connection between the atomizing electrode support 134 and the liquid storage tank 11 as an example. In other embodiments, the atomizing electrode support 134 and the liquid storage tank 11 can also be connected in other ways, such as a rotating connection.

[0061] Furthermore, the liquid storage chamber 11 is provided with a plurality of first positioning parts (not shown in the figure), and the atomizing electrode support 134 is provided with a second positioning part (not shown in the figure). The second positioning part is used to cooperate with the plurality of first positioning parts at multiple positions, so that the atomizing electrode support 134 is relatively fixed relative to the liquid storage chamber 11 at each position through the cooperation of the first positioning part and the second positioning part.

[0062] Optionally, in one embodiment, one of the first positioning part and the second positioning part is a slot, and the other of the first positioning part and the second positioning part is a protrusion. The slot is used to engage with the protrusion, so that the atomizing electrode support 134 engages with the liquid storage tank 11.

[0063] Alternatively, in another embodiment, one of the first positioning part and the second positioning part is a magnetic positioning part. For example, the first positioning part is a magnetic positioning part, and the second positioning part is metal. The first positioning part adsorbs the second positioning part.

[0064] Unlike existing technologies, the atomizer for an aerosol generating device provided in this application includes: a liquid storage chamber for storing an aerosol generating matrix; an atomizing core disposed within the liquid storage chamber, the atomizing core absorbing and heating the aerosol generating matrix to generate aerosol; and an atomizing electrode assembly including a first atomizing electrode, a second atomizing electrode, a third atomizing electrode, and an atomizing electrode support. The first, second, and third atomizing electrodes are electrically connected to the atomizing core and respectively mounted on the atomizing electrode support. The atomizing electrode support is movably connected to the liquid storage chamber, which is inserted into the main unit of the aerosol generating device, allowing the atomizing electrode support to move to multiple positions relative to the liquid storage chamber. The first atomizing electrode is oriented in a scalable manner relative to the main unit. The atomizing electrode is in a conductive state, and one of the second and third atomizing electrodes is conductive to the main unit; or the first, second, and third atomizing electrodes are each conductive to the main unit. This results in different atomization resistances of the atomizing core at different locations, allowing the atomizing core to operate at different output powers while the main unit operates at the same output voltage. This results in the aerosol generating matrix producing different amounts of aerosol, 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 generating 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.

[0065] The above description is only a partial embodiment of this application and does not limit the scope of protection of this application. 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.
