[0012] In one specific embodiment, the number of host air inlets is multiple, and the multiple host air inlets are respectively disposed on different sides of the host body. The maximum air intake area of ​​one of the multiple host air inlets is less than or equal to the minimum air intake area of ​​another of the multiple host air inlets.

[0034] 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.

[0035] Please refer to the following: Figure 2 , Figure 3 and Figure 4 , 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 one embodiment of the atomizer. Figure 4 yes Figure 2 A cross-sectional schematic diagram of another embodiment of the atomizer. In this embodiment, the atomizer 10 includes a liquid storage chamber 11, an atomizing core 12, and an atomizing electrode 13.

[0036] The liquid storage chamber 11 is used to store the aerosol matrix.

[0037] Specifically, 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 the aerosol matrix.

[0038] 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 bottom wall 11a and the peripheral side wall 11b mentioned above. 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.

[0039] 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.

[0040] Among them, the atomizing air inlet 102, for example Figure 3 As shown, it is disposed on the bottom wall 11a, or as... Figure 4 The shown is located on the peripheral sidewall 11b.

[0041] Furthermore, 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Specifically, the atomizing core 12 has an atomizing channel 103, which is connected to the atomizing air inlet 102 and the air outlet 101 respectively. When the atomizing core 12 absorbs and heats the aerosol matrix, aerosol is generated in the atomizing channel 103, so that the external air entering from the atomizing air inlet 102 will discharge the generated aerosol from the air outlet 101.

[0046] The atomizing core 12 includes a liquid-absorbing element 121, a heating element 122, and an atomizing tube 123. The atomizing tube 123 is disposed in the liquid storage chamber 110 and has a liquid inlet 104. The liquid-absorbing element 121 is disposed in the atomizing tube 123 and absorbs the aerosol matrix through the liquid inlet 103. The liquid-absorbing element 121 has the aforementioned atomizing channel 103. The heating element 122 is used to heat the aerosol matrix absorbed by the liquid-absorbing element 121 and generate aerosol in the atomizing channel 103.

[0047] The atomizing electrode 13 is electrically connected to the atomizing core 12. In this embodiment, the atomizing electrode 13 is also electrically connected to the heating element 122 to supply power to the heating element 122, thereby enabling the heating element 122 to heat the aerosol matrix.

[0048] Please see Figure 5 , Figure 5 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 an electromagnet 22.

[0049] Please refer to the following: Figure 6 and Figure 7 , Figure 6 yes Figure 5 A cross-sectional schematic diagram of the main unit 21. Figure 7 yes Figure 6 A cross-sectional schematic diagram of the middle shell 2111, wherein the main body 21 has a receiving cavity 201.

[0050] The main body 21 includes a housing assembly 211 and a power supply assembly 212, and the housing assembly 211 forms a receiving cavity 201.

[0051] 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.

[0052] 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.

[0053] Further reading Figure 5 The main body 21 also has a main body air inlet 210, which is connected to the accommodating cavity 201 and is located along the opening direction of the accommodating cavity 201, that is, as shown in the figure. Figure 5 The B shown extends upwards.

[0054] The accommodating cavity 201 is used to insert the atomizer 10, so that the main unit air inlet 210 is connected to the atomizer air inlet 102, that is, when the atomizer 10 is in such a position... Figure 1 After component A is inserted upwards into the receiving cavity 201, the atomizing air inlet 102 connects to the receiving cavity 201, thereby connecting the main unit air inlet 210 with the atomizing air inlet 102. This is understandable. Figure 1 A direction in the middle and Figure 5 In the diagram, direction B represents two opposite directions.

[0055] The electromagnet 22 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.

[0056] In this embodiment, the electromagnet 22 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 22 is also electrically connected to the power supply 2121.

[0057] Furthermore, the electromagnet 22 is used to generate different magnetic forces to drive the atomizer 10 to move to multiple positions respectively. In this embodiment, the magnetic force generated by the electromagnet 22 interacts with the adsorption member 113, thereby driving the atomizer 10 to move.

[0058] When the atomizer 10 moves to multiple positions, the air intake area of ​​the main unit's air inlet 210 is different at different positions, which results in different air intake volumes at different positions. In this way, the user can adjust the air intake volume of the main unit's air inlet 210 according to actual needs through the electromagnet 22, so that the atomizer 10 produces aerosols of different atomization amounts at different positions, increasing the usage modes and improving the convenience of use.

[0059] Please refer to the following: Figure 3 , Figure 5 , Figure 8 and Figure 9 , Figure 8 yes Figure 3 The atomizing air inlet 102 and Figure 5A schematic diagram of the air intake 210 of the main unit in the first position. Figure 9 yes Figure 3 The atomizing air inlet 102 and Figure 5 A schematic diagram of the main unit's air inlet 210 at the second position. In this embodiment, the atomizing air inlet 102 is disposed on the bottom wall 11a. The air intake area of ​​the main unit's air inlet 210 is the area of ​​the portion of the main unit's air inlet 210 not covered by the atomizer 10. When the atomizer 10 is inserted into the receiving cavity 201, the electromagnet 22 generates a first magnetic force, which drives the atomizer 10 to move to the position shown in the diagram. Figure 8 In the first position shown, the air intake area of ​​the main unit's air intake 210 is S1. When the electromagnet 22 generates a first magnetic force, this first magnetic force drives the atomizer 10 to move to the position shown. Figure 9 In the second position shown, the air intake area of ​​the main unit air intake 210 is S2. It can be clearly seen that S1 > S2. That is, when the atomizer 10 is in the first position, the air intake area S1 of the main unit air intake 210 in the first position is greater than the air intake area S2 of the main unit air intake 210 in the second position. Correspondingly, the air intake volume of the main unit air intake 210 in the first position is greater than the air intake volume of the main unit air intake 210 in the second position.

[0060] Please refer to the following: Figure 4 , Figure 5 and Figure 10 , Figure 10 yes Figure 4 The atomizing air inlet 102 and Figure 5 A schematic diagram of the air intake 210 of the main unit. In this other embodiment, the atomizing air intake 102 is provided on the peripheral sidewall 11b. In this case, when the atomizer 10 is inserted into the receiving cavity 201, as shown... Figure 10 As shown, the air intake area S of the main unit air intake 210 is the overlapping area of ​​the atomizing air intake 102 and the main unit air intake 210. When the electromagnet 22 generates the first magnetic force and the second magnetic force respectively to drive the atomizer 10 to move to the first position and the second position respectively, the overlapping area of ​​the atomizing air intake 102 and the main unit air intake 210 is different, so that the air intake area of ​​the main unit air intake 210 at the first position is different from that at the second position. Correspondingly, the air intake volume of the main unit air intake 210 at the first position is also different from that at the second position.

[0061] Please also refer to 11. Figure 12 and Figure 13 , Figure 11 yes Figure 5 A schematic diagram of another embodiment of the main unit's air intake 210. Figure 12 yes Figure 4 The atomizing air inlet 102 and Figure 11A schematic diagram of the air intake principle of the main unit's air intake 210 in the first position. Figure 13 yes Figure 4 The atomizing air inlet 102 and Figure 11 The schematic diagram of the air intake principle of the main unit air intake 210 in the second position is shown. In this further embodiment, the atomizing air intake 102 is disposed on the peripheral sidewall 11b, and the opening area of ​​the main unit air intake 210 gradually increases or gradually decreases in the opening direction B of the accommodating cavity 201. Figure 11 Taking the opening area of ​​the main unit's air inlet 210 as an example, which gradually decreases in the opening direction B of the accommodating cavity 201 and gradually increases in the insertion direction A of the atomizer 10, when the electromagnet 22 generates a first magnetic force, and this first magnetic force drives the atomizer 10 to move to a first position, such as... Figure 12 As shown, the overlapping area of ​​the atomizing air inlet 102 and the main unit air inlet 210 is S10, that is, the air intake area of ​​the main unit air inlet 210 at the first position is S10. When the electromagnet 22 generates a second magnetic force, and this second magnetic force drives the atomizer 10 to move to the second position, as shown... Figure 13 As shown, the overlapping area of ​​the atomizing air inlet 102 and the main unit air inlet 210 is S20, that is, the air intake area of ​​the main unit air inlet 210 in the second position is S20. It can be clearly seen that S10 < S20, that is, when the atomizer 10 is in the first position, the air intake area S10 of the main unit air inlet 210 in the first position is smaller than the air intake area S20 of the main unit air inlet 210 in the second position. Correspondingly, the air intake volume of the main unit air inlet 210 in the first position is greater than the air intake volume of the main unit air inlet 210 in the second position. Figure 12 and Figure 13 The dashed part represents the atomizing air inlet 102, the solid part represents the main unit air inlet 210, and the shaded part represents the overlapping part of the atomizing air inlet 102 and the main unit air inlet 210.

[0062] Optionally, in another embodiment, there are multiple main unit air inlets 210, which are respectively disposed on different sides of the main unit body 21. The maximum air intake area of ​​one of the multiple main unit air inlets 210 is less than or equal to the minimum air intake area of ​​another of the multiple main unit air inlets 210.

[0063] For ease of explanation, Figure 11Taking two main unit air inlets 210 as an example, namely main unit air inlet 210a and main unit air inlet 210b, the maximum air intake area of ​​main unit air inlet 210a is less than or equal to the minimum air intake area of ​​main unit air inlet 210b. That is, the maximum overlapping area between main unit air inlet 210a and atomizing air inlet 102 is less than or equal to the minimum overlapping area between main unit air inlet 210b and atomizing air inlet 102. In practical applications, the depth of the accommodating cavity 201 is limited, that is, the length of the main unit air inlet 210 in the opening direction B is also limited. Through this setting, the air intake area required by the user can be increased within the limited depth of the accommodating cavity 201. At the same time, it can avoid the problem of the aerosol generating device 1 being too long in order to increase the air intake area required by the user. For example, when the electromagnet 22 drives the atomizer 10 to move to multiple positions, the main unit... The overlapping areas of the air inlet 210a and the atomizer air inlet 102 are 1S, 2S, and 3S, respectively, where S represents the area unit. The overlapping areas of the main unit air inlet 210b and the atomizer air inlet 102 are 4S, 5S, and 6S, respectively. When the user needs an air inlet area of ​​1S, 2S, and 3S, the atomizer 10 can be rotated so that the atomizer air inlet 102 faces the main unit air inlet 210a and inserted into the receiving cavity 201. When the user needs an air inlet area of ​​4S, 5S, and 6S, the atomizer 10 can be rotated so that the atomizer air inlet 102 faces the main unit air inlet 210b and inserted into the receiving cavity 201. Therefore, if only the main unit air inlet 210a or the main unit air inlet 210b is provided, it can only meet the air inlet area corresponding to the main unit air inlet 210a or the main unit air inlet 210b, and cannot meet the other air inlet areas required by the user.

[0064] Please see Figure 14 , Figure 14 Figure 5 A schematic diagram of another embodiment of the main unit air inlet 210. In this embodiment, the main unit air inlet 210 includes a plurality of air inlets 2101, which are arranged sequentially along the opening direction B of the accommodating cavity 201.

[0065] Among them, the opening area of ​​the multiple air inlets 2101 gradually increases, gradually decreases, or remains unchanged in the opening direction B of the accommodating cavity 201.

[0066] For example, the opening area of ​​multiple air inlets 2101 remains unchanged in the opening direction B of the accommodating cavity 201. When the atomizer 10 moves to multiple positions, the atomizing air inlet 102 can overlap with different numbers of air inlets 2101, thereby making the air inlet area of ​​the main unit air inlet 210 different at multiple positions.

[0067] For example, the opening area of ​​multiple air inlets 2101 gradually increases or decreases in the opening direction B of the accommodating cavity 201. When the atomizer 10 moves to multiple positions, the atomizing air inlet 102 can overlap with different air inlets 2101, so that the air inlet area of ​​the main unit air inlet 210 is different at multiple positions.

[0068] Further reading Figure 5 In this embodiment, the housing assembly 211 is further provided with a toggle mechanism 23, 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 23. In this embodiment, the toggle mechanism 23 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 23. This causes the power supply 2121 to adjust the magnitude or direction of the supplied current. For example, when the toggle mechanism 23 is in a certain position... Figure 5 When C1 is toggled upwards, the power supply assembly 212 supplies power to the electromagnet 22, generating a magnetic force that attracts the atomizer 10's suction element 113, bringing the atomizer 10 closer to the main unit 20. 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 23 is moved upwards... Figure 5 When 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 22 becomes a repulsive force. This repulsive force repels the adsorption component 113 on the atomizer 10, causing the atomizer 10 to move away from the main unit 20 and thus move to different positions.

[0069] Unlike existing technologies, the main unit for an aerosol generating device provided in this application includes: a main unit body, which has a accommodating cavity and a main unit air inlet. The accommodating cavity is used to insert the atomizer of the aerosol generating device. The main unit air inlet communicates with the accommodating cavity and extends along the opening direction of the accommodating cavity. An electromagnet is disposed on the side of the main unit body facing the opening direction of the accommodating cavity. The electromagnet generates different magnetic forces to drive the atomizer to move to multiple positions. The air intake area of ​​the main unit air inlet is different at different positions, resulting in different air intake volumes at different positions. In this way, the user can adjust the air intake volume of the main unit air inlet according to actual needs by using the electromagnet, thereby enabling the atomizer to generate different amounts of aerosol at different positions, increasing usage modes and improving ease of use.
