Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of aerosol generation, and in particular to an aerosol generating system. Background Art

[0002] A nebulizer is a device that can atomize a liquid preparation to form an aerosol. In some exemplary prior arts, a nebulizer is a portable device, including a battery cell and an atomizer assembly, wherein the battery cell is used to provide power to the atomizer assembly so that the atomizer assembly can atomize a liquid matrix to generate an aerosol. However, due to the limitation of the amount of electricity in the battery cell, the amount of electricity in the battery cell is usually exhausted in a relatively short period of time. When the amount of electricity in the battery cell is exhausted, there is still a large amount of liquid matrix in the nebulizer to be atomized. Therefore, the user needs to charge the nebulizer or replace the battery cell, thereby having to suspend the use of the nebulizer, which reduces the user experience. Utility Model Content

[0063] Please refer to Figure 1-Figure 4An embodiment of the present application provides an aerosol generating system, which includes an atomizer 1 and a power supply 2. In the system, the atomizer 1 includes a first battery cell 11 and an atomizer assembly 12. The first battery cell 11 and the atomizer assembly 12 can be conductively connected, so that when the atomizer 1 is separated from the power supply 2 and exists independently of the power supply 2, the atomizer assembly 12 in the atomizer 1 can atomize the liquid matrix based on the power obtained from the first battery cell 11 in the atomizer 1, thereby generating an aerosol; at the same time, in the system, the power supply 2 includes a second battery cell 21. When the atomizer 1 is engaged with the power supply 2, a conductive path is established between the atomizer 1 and the power supply 2, and the atomizer 1 can obtain power from the second battery cell 21 based on the conductive path. The power obtained by the atomizer 1 from the power supply 2 can be used to charge the first battery cell 11 to supplement the insufficient power in the first battery cell 11, and / or can be used to provide power for the atomizer assembly 12 to atomize the liquid matrix, so that the atomizer assembly 12 can atomize the liquid matrix based on the power provided by the second battery cell 21.

[0064] In one embodiment of the present application, when the atomizer 1 is coupled with the power supply 2, a conductive path is established between the two, and the conductive path includes a first conductive path, and the second battery cell 21 can charge the first battery cell 11 through the first conductive path to supplement the power and quantity of the first battery cell 11 when the power of the first battery cell 11 is insufficient. In one embodiment of the present application, when the atomizer 1 is coupled with the power supply 2, a conductive path is established between the two, and the conductive path includes a second conductive path, and the second battery cell 21 can directly provide power to the atomization assembly 12 through the second conductive path, so that the atomization assembly 12 can atomize the liquid matrix based on the power provided by the second battery cell 21, so that when the power of the first battery cell 11 is insufficient or when the first battery cell 11 is being charged, the power for atomizing the liquid matrix can be provided to the atomization assembly 12 instead of the first battery cell 11, so that the user can continue to use the atomizer 1.

[0065] Preferably, when the atomizer 1 is coupled with the power supply 2, the atomizer 1 and the power supply 2 form a first conductive path and a second conductive path at the same time. It should be noted that when the first conductive path and the second conductive path are formed between the atomizer 1 and the power supply 2 at the same time, the first conductive path and the second conductive path can be turned on at the same time, so that the second battery core 21 can directly provide power for the atomization assembly 12 to atomize the liquid matrix while charging and replenishing the power and electricity for the first battery core 11. Therefore, the atomizer 1 can also generate aerosol for the user to use while charging. However, at the same time, at least one of the first conductive path and the second conductive path can also be disconnected. For example, if the power in the first battery core 11 is already full, the first conductive path can be disconnected, and at the same time, the second conductive path can continue to be turned on, so that the second battery core 21 can continue to provide power for the atomization assembly 12 to atomize the liquid matrix. Of course, the second conductive path can also be disconnected when the power and electricity in the first battery core 11 are relatively sufficient, and then the first battery core 11 provides power for the atomization assembly 12 to atomize the liquid matrix.

[0066] It should be noted that, in other embodiments, when the atomizer 1 is connected to the power supply 2, only the second conductive path of the first conductive path and the second conductive path can be established between the atomizer 1 and the power supply 2. Therefore, when the power of the first battery cell 11 is insufficient, the power supply 2 can replace the first battery cell 11 in the atomizer 1 to provide power to the atomization assembly 12, so that the atomizer 1 can continue to be used, and the user does not need to replace the atomizer 1, replace the first battery cell 11, or suspend the use of the atomizer 1 to charge the first battery cell 11.

[0067] Since the power supply 2 includes the second battery cell 21, the power supply 2 can be a portable power supply device, so that the power supply 2 can be carried by the user, so that when the power of the first battery cell 11 is insufficient, the power supply 2 can provide power for the atomization component 12 to atomize the liquid matrix and generate aerosol based on the established second conductive path anytime and anywhere, or charge the first battery cell 11 and replenish the power and power of the first battery cell 11 based on the first conductive path anytime and anywhere. Of course, when the power of the first battery cell 11 is relatively sufficient, the power supply 2 can also provide power for the atomization component 12 to atomize the liquid matrix and generate aerosol based on the second conductive path, so as to reduce the power supply burden of the first battery cell 11 and reduce the power consumption of the first battery cell 11.

[0068] The first battery cell 11 and the second battery cell 21 can be any suitable battery cell, such as a DC source, such as a battery. In one embodiment, the battery is a lithium-ion battery. Alternatively, the battery can be a nickel metal hydride battery, a nickel cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or a lithium polymer battery. The first battery cell 11 and the second battery cell 21 can both be rechargeable batteries that can be charged to replenish their power when their power is reduced or exhausted. In one example, the first battery cell 11 is a disposable battery cell. In one example, the second battery cell 21 is a disposable battery cell. In one example, the second battery cell 21 is a rechargeable battery cell, so that the second battery cell 21 can be charged by connecting the power supply 2 via a charger, so that the power supply 21 can be reused.

[0069] The volume of the second battery cell 21 may be greater than or equal to the volume of the first battery cell 11. The second battery cell 21 may be a collection of multiple battery cells connected in series. Preferably, the maximum power reserve of the second battery cell 21 is greater than or equal to the maximum power reserve of the first battery cell 11.

[0070] In one embodiment of the present application, reference may be made to Figure 5-Figure 8 The atomizer 1 further includes a switch Q1, which can be switched between a first state and a second state. When the switch Q1 is in the first state, a conductive connection is established between the first battery core 11 and the atomizer assembly 12, so that the first battery core 11 can provide power to the atomizer assembly 12. When the atomizer 1 is engaged with the power supply 2, while the above-mentioned conductive path is formed between the atomizer 1 and the power supply 2, the switch Q1 can also be changed to a second state different from the first state.

[0071] As an example, when the switch Q1 is in the second state, the conductive connection between the first battery cell 11 and the atomizer assembly 12 is disconnected. In other words, when the first conductive path is turned on, the conductive connection between the first battery cell 11 and the atomizer assembly 12 is disconnected, so that when the second battery cell 21 is charging, replenishing power, and electricity for the first battery cell 11, the first battery cell 11 is prohibited from discharging to the atomizer assembly 12; or, when the second conductive path is turned on, the conductive connection between the first battery cell 11 and the atomizer assembly 12 is disconnected, so that when the second battery cell 21 provides power to the atomizer assembly 12, the first battery cell 11 is prohibited from providing power to the atomizer assembly 12.

[0072] As an example, see Figure 8, the atomizer assembly 12 includes a first heating element 121 and a second heating element 123, both of which can atomize the liquid matrix by generating heat. When the switch Q1 is in the first state, the first battery cell 11 is only electrically connected to the first heating element 121 of the first heating element 121 and the second heating element 123, so that the first battery cell 11 can only provide power to the first heating element 121 of the first heating element 121 and the second heating element 123; when the atomizer 1 is engaged with the power supply, a second conductive path is established, and the second battery cell 21 is only electrically connected to the second heating element 123 of the first heating element 121 and the second heating element 123 through the second conductive path, so that the second battery cell 21 can only provide power to the second heating element 123 of the first heating element 121 and the second heating element 123 through the second conductive path. In this example, when the second conductive path is turned on, the conductive connection between the first battery cell 11 and the first heating element 121 can also be turned on, and the two are not mutually exclusive, so that the first battery cell 11 and the second battery cell 21 can be discharged at the same time, and can provide power to the first heating element 121 and the second heating element 122 at the same time. After the atomizer 1 and the power supply 2 are connected to form the second conductive path, if the switch Q1 is changed to the second state, the conductive connection between the first battery cell 11 and the first heating element 121 is disconnected, but the switch Q1 does not affect the continued conduction of the second conductive path, so the second battery cell 21 can continue to provide power to the second heating element 123.

[0073] Furthermore, the switch Q1 is configured to automatically change from the first state to the second state when the atomizer 1 is engaged with the power supply 2. Based on this, the power supply 2 further includes a trigger mechanism 22. When the atomizer 1 is engaged with the power supply 2, the trigger mechanism 22 triggers the switch Q1 to change the switch Q1 to the second state.

[0074] The switch Q1 can be configured to maintain the first state when the atomizer 1 is separated from the power supply 2. Thus, when the atomizer 1 is engaged with the power supply 2, the trigger mechanism 22 triggers the switch Q1, so that the switch Q1 changes from the first state to the second state. When the atomizer 1 is separated from the power supply 2, the trigger mechanism 22 releases the triggering of the switch Q1, so that the switch Q1 can automatically return to the first state from the second state.

[0075] Of course, the state of the switch Q1 can also be changed manually. In this way, when the atomizer 1 is separated from the power supply 2, if the switch Q1 is already in the second state, then when the atomizer 1 is connected to the power supply 2, the user does not need to operate, and the switch continues to maintain the second state; and if the switch Q1 is already in a state different from the second state, then when the atomizer 1 is connected to the power supply 2, the user manually operates the trigger mechanism 22 to change the switch Q1 to the second state.

[0076] The switch Q1 may include a contact switch, which refers to a switch element that causes at least part of its components to deform or displace through direct physical contact, thereby disconnecting or connecting the circuit in which it is located.

[0077] In one example, the trigger mechanism 22 needs to keep in contact with the contact switch to maintain the second state of the switch Q1. When the trigger mechanism 22 is separated from the contact switch, the switch Q1 automatically returns to the first state. For example, the contact switch can be a touch switch. Based on this, when the atomizer 1 is engaged with the power supply 2, the trigger mechanism 22 keeps in contact with the contact switch.

[0078] In one example, the contact switch has a self-locking property, and the trigger mechanism 22 abuts against the contact switch, so that at least part of the components of the contact switch move and maintain the second state through self-locking. When the trigger mechanism 22 is separated from the contact switch, other operations are required to release the self-locking state of the contact switch to restore it to the first state. For example, the contact switch can be a toggle switch, etc. Based on this, during at least part of the stroke when the atomizer 1 and the power supply 2 are engaged, the trigger mechanism 22 contacts the contact switch.

[0079] Alternatively, the switching switch Q1 may include a proximity switch Q11. The proximity switch Q11 is a contactless switch element, which includes a sensing device, and is triggered by sensing the distance between the proximity switch Q11 and the trigger mechanism 22, or by sensing the proximity of the trigger mechanism 22, the distance of the trigger mechanism 22, or the travel of the trigger mechanism 22. When the trigger mechanism 22 triggers the proximity switch, there may be no direct contact with the contact switch Q11, but there may be direct contact. When the atomizer 1 is engaged with the power supply 2, the trigger mechanism 22 is in the sensing trigger range of the proximity switch Q11. Thus, when the atomizer 1 and the power supply 2 remain engaged: the proximity switch Q11 can be triggered by the proximity of the trigger mechanism 22 to the atomizer 1 during the engagement process of the power supply 2, and then change to the second state and maintain the second state; or, the proximity switch Q11 can be released from the trigger mechanism 22 when the atomizer 1 is separated from the power supply 2, and then automatically change to the first state and maintain the first state; or, the proximity switch Q11 can be triggered when the distance between the proximity switch Q11 and the trigger mechanism 22 is less than or equal to a preset value, and then change to the second state and maintain the second state; or, the proximity switch Q11 can be released from the trigger mechanism 22 when the distance between the proximity switch Q11 and the trigger mechanism 22 is greater than a preset value, and then change to the first state and maintain the first state.

[0080] In one example, the proximity switch Q11 includes an eddy current proximity switch, and the trigger mechanism 22 includes a conductor. When the eddy current proximity switch is close to the conductor, eddy currents are generated inside the eddy current proximity switch, causing at least one electrical parameter to change, thereby triggering the proximity switch.

[0081] In one example, the proximity switch Q11 includes a capacitive proximity switch. Regardless of whether the trigger mechanism 22 includes a conductor, when the trigger mechanism approaches the capacitive proximity switch, the dielectric constant of the capacitor in the capacitive proximity switch changes, thereby causing the proximity switch to be triggered.

[0082] In one example, the proximity switch Q11 includes a Hall proximity switch, which includes a magnetic sensitive element, and the trigger mechanism 22 includes a magnetic body. When the Hall proximity switch approaches the magnetic body, the Hall effect is generated, causing the internal circuit state of the switch to change, thereby causing the proximity switch to be triggered.

[0083] In one example, the proximity switch Q11 includes a photoelectric proximity switch, which is a switch made using the photoelectric effect. The trigger mechanism 22 includes an optical device or a shading device. When the photoelectric proximity switch approaches the trigger mechanism 22, so that the photoelectric proximity switch can receive a light signal emitted by the optical device or a reflected light signal, or the shading device blocks the light signal entering the photoelectric proximity switch, at least one electrical parameter of the photoelectric proximity switch changes, thereby causing the proximity switch to be triggered.

[0084] In one example, the proximity switch Q11 includes a pyroelectric proximity switch, which includes an element that can sense temperature changes. The trigger mechanism 22 includes a pyroelectric. When the pyroelectric proximity switch approaches a pyroelectric with a preset temperature, at least one electrical parameter of the pyroelectric proximity switch changes, causing the proximity switch to be triggered.

[0085] Of course, the proximity switch Q11 may also be other proximity switches.

[0086] In one embodiment of the present application, reference may be made to Figure 1-Figure 4 The atomizer 1 further comprises a suction nozzle 13 in fluid communication with the atomizing assembly 12. When the atomizer 1 is coupled with the power supply 2, the suction nozzle 13 is exposed outside the power supply 2 for the user to hold in the mouth, so that when the atomizer 1 is coupled with the power supply 2, it is convenient for the user to inhale the atomizer 1. When the atomizer 1 is separated from the power supply 2 and exists independently, the user also inhales the atomizer 1 through the suction nozzle 13.

[0087] Furthermore, the atomizer 1 also includes a first shell 14, which has a liquid storage chamber 141 for storing a liquid matrix. At least a portion of the atomizer assembly 12 is disposed in the first shell 14 and is fluidically connected to the liquid storage chamber 141, so that the atomizer assembly 12 can absorb the liquid matrix in the liquid storage chamber 141 and can atomize at least a portion of the liquid matrix absorbed by it when obtaining electricity, thereby generating an aerosol.

[0088] The suction nozzle 13 and the first shell 14 are connected to each other or the suction nozzle 13 and the first shell 14 are integrally formed.

[0089] The atomizer 1 may further include a first base 15 , which is connected to the first shell 14 and supports the first battery cell 11 , so that at least a portion of the first battery cell 11 is retained in the first shell 14 , or at least a portion of the first battery cell 11 is retained on the first base 15 .

[0090] The atomizer 1 may further include a sealing plug 16, at least part of which is arranged inside the first housing 14 and is sealed to the inner wall of the first housing 14, the sealing plug 16 defines at least part of the boundary of the liquid storage chamber 141, and the sealing plug 16 is used to seal the liquid matrix in the liquid storage chamber 141 to prevent the liquid matrix from leaking. The sealing plug 16 may be made entirely of a flexible material such as silicone or rubber. The sealing plug 16 may include a support seat and a sealing ring providing a sealing connection between the support seat and the first housing 14. The first base 15 may support the sealing plug 16 so that the sealing plug 16 can be hidden and maintained in the first housing 14. The first battery core 11 may be arranged between the first base 15 and the sealing plug 16, and the sealing plug 16 can prevent the liquid matrix from leaking onto the first battery core 11.

[0091] The power supply 2 may include a second housing 23, in which the second battery cell 21 is accommodated, and the second housing 23 may have a receiving cavity 231. When the atomizer 1 is coupled to the power supply 2, a portion of the atomizer 1 is received in the receiving cavity 231, and the mouthpiece 13 is exposed outside the receiving cavity 231. One end of the receiving cavity 231 may be open to allow the atomizer 1 to enter.

[0092] The power supply 2 may further include a second base 24 , which is disposed in the second shell 23 and defines a portion of the boundary of the receiving cavity 231 . When the atomizer 1 is coupled to the power supply 2 , the second base 24 may support the atomizer 1 .

[0093] The atomizer 1 is detachably connected to the second housing 23 and / or the second base 24, so that the atomizer 1 can be removed from the receiving chamber 231. For example, Figure 2-Figure 4 The first base 15 is provided with a first magnetic member 17, and the second base 24 is provided with a second magnetic member 25. When the atomizer is received in the receiving cavity 231, the first magnetic member 17 and the second magnetic member 25 are magnetically attracted to each other, so that the atomizer 1 can be stably connected to the power supply 2.

[0094] In one example, the switch Q1 is disposed on the first base 15. In one example, the switch Q1 is disposed on the first housing 14. In one example, the trigger mechanism 22 is disposed on the second base 24. In one example, the trigger mechanism 22 is disposed on the second housing 23.

[0095] In one embodiment of the present application, reference may be made to Figure 4-Figure 8, the atomization assembly 12 includes a first heating element 121 and a second heating element 123, and the first heating element 121 and the second heating element 122 can both heat the liquid matrix, so that the liquid matrix evaporates and atomizes to form an aerosol. Among them, the first battery core 11 can be conductively connected to the first heating element 121, so that the first battery core 11 can provide electricity for the first heating element 121 to heat the liquid matrix. The second battery core 21 is electrically connected to the first heating element 121 and / or the second heating element 123 through a second conductive path, so that when the second conductive path is formed and turned on, the second battery core 21 is conductively connected to the first heating element 121 and / or the second heating element 123, and the second battery core 21 can provide electricity for the first heating element 121 and / or the second heating element 123 to heat the liquid matrix.

[0096] In one example, refer to Figure 5-Figure 7 When the second conductive path is formed and turned on, or when the atomizer 1 is connected to the power supply 2, the first heating element 121 and the second heating element 123 are connected in parallel, and the first heating element 121 and the second heating element 123 are both electrically connected to the second battery core 21, so that the second battery core 21 can provide power for the first heating element 121 to heat the liquid matrix, and can also provide power for the second heating element 123 to heat the liquid matrix. Among them, the second battery core 21 can provide power to the first heating element 121 and the second heating element 123 at the same time. Of course, since the first heating element 121 and the second heating element 123 are connected in parallel, the first heating element 121 and the second heating element 123 can also be controlled to obtain power from the second battery core 21 successively, or not at the same time.

[0097] In another example, see Figure 8 When the second conductive path is formed and turned on, or when the atomizer 1 is connected to the power supply 2, the second battery cell 21 is conductively connected only to the second heating element 123 of the first heating element 121 and the second heating element 123 through the second conductive path, so that after the atomizer 1 is connected to the power supply 2, the second battery cell 21 in the power supply 2 can only provide power to the second heating element 123 of the first heating element 121 and the second heating element 123 to atomize the liquid matrix, but cannot also provide power to the first heating element 121.

[0098] In one embodiment of the present application, reference may be made to Figure 4 The atomization assembly 12 further includes a first liquid absorption element 122 and a second liquid absorption element 124, both of which are capable of absorbing liquid matrices. The first heating element 121 and the second heating element 123 are respectively disposed on the first liquid absorption element 122 and the second liquid absorption element 124, so as to respectively atomize at least part of the liquid matrices on the first liquid absorption element 122 and the second liquid absorption element 124 to form aerosol.

[0099] The first absorbent element 122 may include porous ceramic, porous glass matrix, porous plastic matrix, porous metal matrix, etc. The first absorbent element 122 may include fibers such as cotton core, cotton rope, etc. The porosity of the first absorbent element 122 may be 25% to 85%, or its average pore size may be 5 μm to 40 μm.

[0100] The first absorbent element 122 and the second absorbent element 124 may be made of the same material, have the same porosity or the same average pore size, and have the same or substantially the same structural features.

[0101] The first heating element 121 may be a heating circuit, a heating film, a heating track or a heating net disposed on the first liquid absorbing element 122. The first heating element 122 may be a heating coil wound on the first liquid absorbing element 122. The second heating element 123 may be a heating circuit, a heating film, a heating track or a heating net disposed on the second liquid absorbing element 124. The second heating element 123 may be a heating coil wound on the second liquid absorbing element 124.

[0102] In one example, refer to Figure 4 , the atomizer 1 has only one liquid storage chamber 141, and the first liquid absorption element 122 and the second liquid absorption element 124 are both in fluid communication with the liquid storage chamber 141, so that the first liquid absorption element 122 and the second liquid absorption element 124 can absorb the liquid matrix in the liquid storage chamber 141, and the liquid matrix atomized by the first heating element 121 and the second heating element 123 comes from the liquid matrix in the liquid storage chamber 141. When the first battery core 11 can only provide power to the first heating element 121 of the first heating element 121 and the second heating element 123, and the second battery core 21 can only provide power to the second heating element 123 of the first heating element 121 and the second heating element 123, this example can be applied, but is not limited thereto.

[0103] Alternatively, in one example, the atomizer has a first liquid storage chamber and a second liquid storage chamber, and the first liquid storage chamber and the second liquid storage chamber are isolated from each other. The first liquid absorption element is in fluid communication with the first liquid storage chamber to absorb the liquid matrix stored in the first liquid storage chamber. The second liquid absorption element is in fluid communication with the second liquid storage chamber to absorb the liquid matrix stored in the second liquid storage chamber.

[0104] Alternatively, in one example, the atomizer has a first liquid storage chamber and a second liquid storage chamber, and the first liquid storage chamber and the second liquid storage chamber are connected to each other. The first liquid absorption element is connected to the first liquid storage chamber fluid to absorb the liquid matrix stored in the first liquid storage chamber, and the liquid matrix in the second liquid storage chamber can flow into the first liquid storage chamber and then be absorbed by the first liquid absorption element. The second liquid absorption element is connected to the second liquid storage chamber fluid to absorb the liquid matrix stored in the second liquid storage chamber, and the liquid matrix in the first liquid storage chamber can flow into the second liquid storage chamber and then be absorbed by the second liquid absorption element. This example can be applied when the first battery core can only provide power to the first heating element of the first heating element and the second heating element, and the second battery core can only provide power to the second heating element of the first heating element and the second heating element, but is not limited to this.

[0105] In such Figure 4 In the embodiment shown, the nebulizer 1 further includes a first airway tube 18 and a second airway tube 19. The aerosol formed by atomizing the liquid matrix on the first liquid absorption element 122 and the aerosol formed by atomizing the liquid matrix on the second liquid absorption element 124 enter the mouthpiece 13 through the first airway tube 18 and the second airway tube 19, respectively. Figure 4 At least a portion of the first absorbent element 122 is disposed in the first airway tube 18, and a hole may be disposed on the first airway tube 18, through which a portion of the first absorbent element 122 may pass into the liquid storage cavity 141 or the first liquid storage cavity, or a liquid matrix in the liquid storage cavity 141 or the first liquid storage cavity may pass through the hole and be absorbed by the first absorbent element 122; and / or, at least a portion of the second absorbent element 124 is disposed in the second airway tube 19, and a hole may be disposed on the second airway tube 19, through which a portion of the second absorbent element 124 may pass into the liquid storage cavity 141 or the second liquid storage cavity, or a liquid matrix in the liquid storage cavity 141 or the second liquid storage cavity may pass through the hole and be absorbed by the second absorbent element 124.

[0106] In one embodiment of the present application, reference may be made to Figure 5-Figure 8 , the atomizer 1 further includes a first power extraction electrode A1 and a second power extraction electrode A2, the opposite ends of the second heating element 123 are electrically connected to the first power extraction electrode A1 and the second power extraction electrode A2 respectively, and the first power extraction electrode A1 and the second power extraction electrode A2 are components of the second conductive path, so that when the atomizer 1 is coupled to the power supply device 2, the first power extraction electrode A1 and the second power extraction electrode A2 are respectively conductively connected to different electrodes of the second battery cell 21. For example, the first power extraction electrode A1 is conductively connected to the negative electrode of the second battery cell 21, and the second power extraction electrode A2 is conductively connected to the positive electrode of the second battery cell 21.

[0107] Correspondingly, you can refer to Figure 2 and Figure 5-Figure 8The power supply device 2 also includes a first power supply electrode B1 and a second power supply electrode B2. Different electrodes of the second battery cell 21 are conductively connected to the first power supply electrode B1 and the second power supply electrode B2 respectively, and the first power supply electrode B1 and the second power supply electrode B2 are components of the second conductive path, so that when the atomizer 1 is coupled to the power supply device 2, the first power supply electrode B1 and the second power supply electrode B2 are electrically connected to opposite ends of the second heating element 123 respectively.

[0108] Specifically, when the atomizer 1 is connected to the power supply device 2, the first power supply electrode B1 and the second power supply electrode B2 are conductively connected to the first power extraction electrode A1 and the second power extraction electrode A2 respectively. Preferably, when the atomizer 1 is connected to the power supply device 2, the first power extraction electrode A1 elastically abuts against the first power supply electrode B1, and the second power extraction electrode A2 elastically abuts against the second power supply electrode B2.

[0109] The first power-collecting electrode A1 and the second power-collecting electrode A2 can be fixed on the first base 15, and can be partially exposed outside the first base 15, or can be hidden in the first base 15 (eg, Figure 3 The first power supply electrode B1 and the second power supply electrode B2 can be fixed on the second base 24, and can partially protrude outside the second base 24.

[0110] When the second battery cell 21 can also provide power to the first heating element 121, in one example, reference can be made to Figure 5-Figure 7 The atomizer 1 also includes a third power-collecting electrode A3. The opposite ends of the first heating element 121 are conductively connected to the first power-collecting electrode A1 and the third power-collecting electrode A3 respectively, and the third power-collecting electrode A3 is a component of the second conductive path. When the atomizer 1 is coupled to the power supply 2, the second power-collecting electrode A2 and the third power-collecting electrode A3 are conductively connected to the same electrode of the second battery cell 21, so that the positive electrode and the negative electrode of the second battery cell 21 are conductively connected to the opposite ends of the first heating element 121 respectively.

[0111] Correspondingly, you can refer to Figure 5-Figure 7 The power supply device 2 also includes a third power supply electrode B3, and the second power supply electrode B2 and the third power supply electrode B3 are conductively connected to the same electrode of the second battery cell 21, so that the third power supply electrode B3 and the first power supply electrode B1 are conductively connected to different electrodes of the second battery cell 21, and the third power supply electrode B3 is a component of the second conductive path. When the atomizer 1 is connected to the power supply device 2, the opposite ends of the first heating element 121 are conductively connected to the first power taking electrode A1 and the third power taking electrode A3, respectively.

[0112] Specifically, when the atomizer 1 is connected to the power supply 2, the first power electrode A1 and the third power electrode A3 are conductively connected to the first power supply electrode B1 and the third power supply electrode B3, respectively. Preferably, when the atomizer 1 is connected to the power supply 2, the first power electrode A1 elastically abuts against the first power supply electrode B1, and the third power electrode A3 elastically abuts against the third power supply electrode B3. The third power electrode A3 can be fixed on the first base 15, and can be partially exposed outside the first base 15, and can also be hidden in the first base 15 (such as Figure 3 The third power supply electrode B3 can be fixed on the second base 24, and can partially protrude outside the second base 24.

[0113] In one embodiment of the present application, reference may be made to Figure 5-Figure 8 The atomizer 1 further includes a first control switch Q2, which is conductively connected between the first battery cell 11 and the first heating element 121. The first battery cell 11 can respond to the triggering of the first control switch Q2 to provide power to the first heating element 121, so that the first heating element 121 generates heat to atomize the liquid matrix.

[0114] The control switch is an electrically controlled switch, and its on or off is controlled by a trigger signal. The trigger signal may come from the control switch itself. For example, when the control switch is a puff detector, the puff detector generates the trigger signal when detecting a puff action, thereby triggering the control switch and turning it on. The trigger signal may come from a controller. For example, when the control switch is a transistor, the transistor can be triggered and turned on in response to the trigger signal sent by the controller.

[0115] In a preferred embodiment of the present application, the first control switch Q2 includes a first suction detector for detecting a suction action, and the first control switch Q2 is configured to be triggered when the atomizer 1 is being sucked. The first suction detector may be an airflow detector, which determines whether the atomizer 1 is being sucked by detecting the flow direction, flow speed or air pressure of the airflow in the atomizer 1, and generates the above trigger signal when it is detected that the atomizer 1 is being sucked, and at the same time, the first control switch Q2 is triggered, so that the first heating element 121 can obtain greater power from the first battery core 11, thereby atomizing the liquid matrix.

[0116] In such Figure 5-Figure 8In the illustrated embodiment, the switch Q1 is conductively connected between the first control switch Q2 and the first battery cell 11. When the atomizer 1 is separated from the power supply 2, if the switch Q1 is in the second state, the conductive connection between the first control switch Q2 and the first battery cell 11 is disconnected, and the first control switch Q2 is therefore in a non-operating state and cannot detect the puffing action. When the atomizer 1 is separated from the power supply 2, if the switch Q1 is in the first state, the first control switch Q2 is conductively connected to the first battery cell 11, and the first battery cell 11 can respond when the atomizer 1 is puffed, and provide power to the atomizer assembly 12, so that at least the first heating element 121 in the atomizer assembly 12 atomizes the liquid matrix.

[0117] Therefore, when the atomizer 1 is connected to the power supply and the switch Q1 is in the second state, the first battery cell 11 cannot provide the operating voltage for the first control switch Q2 or the first puff detector.

[0118] When the second battery cell 21 can only provide power to the second heating element 123 of the first heating element 121 and the second heating element 123, in one example, reference can be made to Figure 8 , the first puff detector (Q2) and the second conductive path are independent of each other, and the trigger signal generated by the first puff detector (Q2) due to detecting that the atomizer 1 is being puffed has no effect on the second conductive path. Further, when the first control switch Q2 is triggered by the first puff detector (Q2) due to detecting that the atomizer 1 is being puffed, only the first battery cell 11 can provide power for the first heating element 121 of the first heating element 121 and the second heating element 123 to atomize the liquid matrix. And / or, when the atomizer 1 is engaged with the power supply 2, if the switching switch Q1 is in the second state, the conductive connection between the first puff detector (Q2) and the first battery cell 11 is disconnected, so that the first puff detector (Q2) is in a non-working state and cannot detect whether the atomizer 1 is being puffed.

[0119] In one embodiment of the present application, reference may be made to Figure 5-Figure 8 , the aerosol generating system further includes a second control switch Q3, in other words, the atomizer 1 or the power supply 2 further includes a second control switch Q3. The second control switch Q3 is arranged on the second conductive path, and when the atomizer 1 is coupled with the power supply 2, the second control switch Q3 is conductively connected between the second battery cell 21 and the second heating element 123, and the second battery cell 21 is configured to respond to the triggering of the second control switch Q3 to provide power to the first heating element 121 and / or the second heating element 123, so that the first heating element 121 and / or the second heating element 123 generate heat to atomize the liquid matrix.

[0120] When the second battery cell 21 can only provide power to the second heating element 123 of the first heating element 121 and the second heating element 123, in one example, reference can be made to Figure 8 The second control switch Q3 is independent of the first control switch Q2, and whether the first control switch Q2 is triggered or not does not affect the switch state of the second control switch Q3. The second control switch Q3 may include a second suction detector for detecting whether the atomizer 1 is puffed. The second control switch Q3 is triggered when the atomizer 1 is puffed, so that the second conductive path is turned on, and the second battery cell 21 provides power for the second heating element 123 to atomize the liquid matrix.

[0121] In order to reduce the cost of the atomizer 1, the second puff detector is preferably a component of the power supply 2, disposed in the second housing 23, and electrically connected to the second battery cell 21, so as to obtain power in a working state and capable of detecting puffs from the second battery cell 21. When the atomizer 1 is engaged with the power supply 2, at least part of the airflow channel in the atomizer 1 is fluidically connected to the second puff detector, so that the second puff detector can detect whether the atomizer 1 is being puffed. Figure 2 and Figure 3 In the illustrated embodiment, a first air hole 151 is provided on the first base 15, and a second air hole 241 is provided on the second base 24. The second air hole 241 is fluidly connected to a second suction detector disposed in the second shell 23. When the atomizer 1 is engaged with the power supply 2, the first air hole 151 is fluidly connected to the second air hole 241. Therefore, when the user has a suction action, at least part of the air in the power supply 2 can enter the first air hole 151 through the second air hole 241, thereby causing the airflow or air pressure at the position of the second suction detector to change, and the second suction detector determines that the atomizer 1 is being sucked based on this change.

[0122] In this example, the second puff detector is conductively connected to the second battery cell 21 and the first power supply electrode B1 or the second power supply electrode B2. Figure 5-Figure 8 In the illustrated embodiment, the second control switch Q3 is conductively connected between the second power supply electrode B2 and the second battery cell 21 .

[0123] When the second battery cell 21 can also provide power to the first heating element 121, in one example, reference can be made to Figure 5-Figure 7 When the atomizer 1 is connected to the power supply 2, the second control switch Q3 is coupled to the first control switch Q2, and whether the first control switch Q2 is triggered or not affects the switch state of the second control switch Q3. For example, when the first control switch Q2 is triggered, the second control switch Q3 can be triggered accordingly, so that the second battery cell 21 can provide power for the first heating element 121 to atomize the liquid matrix, and can also provide power for the second heating element 123 to atomize the liquid matrix.

[0124] In order to reduce the cost of the aerosol generating system, the second control switch Q3 is preferably a transistor. Based on this, the atomizer 1 or the power supply 2 may further include a controller 26, which is used to be conductively connected to the first control switch Q2, so that the controller 1 can obtain a signal that the first control switch Q2 is triggered, and then send a control signal based on the signal to control the second control switch Q3, so that the second control switch Q3 is triggered following the first control switch Q2, and the second conductive path is thus turned on, and the second battery cell 21 provides power to the atomization assembly 12 through the second conductive path.

[0125] In order to further reduce the cost of the atomizer 1, the controller 26 is preferably a component of the power supply 2, and is disposed in the second housing 23. When the atomizer 1 is coupled with the power supply 2, a third conductive path is established between the atomizer 1 and the power supply 2. The controller 26 receives the trigger signal of the first control switch Q2 through the third conductive path, and controls the second control switch Q3 to be triggered. The first control switch Q2 can generate a trigger signal when triggered. The controller 26 is conductively connected to the first control switch Q2 (e.g., the first puff detector) through the third conductive path to receive the trigger signal of the first control switch Q2, and generates a control signal based on the trigger signal to trigger the second control switch Q3, so that the second conductive path is turned on, and the second battery cell 21 provides power to the atomizer assembly 12 through the second conductive path.

[0126] Furthermore, the first control switch Q2 includes a first puff detector for detecting that the atomizer 1 is being puffed. The first control switch Q2 is triggered when it is detected that the atomizer 1 is being puffed. The controller 26 receives the trigger signal of the first puff detector through the third conductive path to control the triggering of the second control switch Q3, so that the second battery cell 21 provides power to the first heating element 121 and the second heating element 123 through the second conductive path.

[0127] In such Figure 5-Figure 7 In the illustrated embodiment, the atomizer 1 further comprises a first signal electrode A4, which is electrically connected to the first suction detector. When the atomizer 1 is engaged with the power supply 2, the controller 26 electrically connects the first signal electrode A4 and the second control switch Q3 to control the triggering of the second control switch Q3 when the atomizer 1 is inhaled. The first signal electrode A4 may be fixed on the first base 15.

[0128] Correspondingly, the power supply 2 further includes a second signal electrode B4. When the atomizer 1 is coupled to the power supply 2, the second signal electrode B4 is conductively connected to the first puff detector, and the controller 26 is conductively connected to the second signal electrode B4 and the second control switch Q3, so as to control the triggering of the second control switch Q3 when the atomizer 1 is puffed. The second signal electrode B4 may be fixed on the second base 24. Specifically, when the atomizer 1 is coupled to the power supply 2, the first signal electrode A4 is conductively connected to the second signal electrode B4, and preferably the first signal electrode A4 and the second signal electrode B4 are conductively connected and communicated by elastic abutment.

[0129] When the second battery cell 21 can also provide power to the first heating element 121, in one example, reference can be made to Figure 5-Figure 7 , one end of the first heating element 121 is conductively connected to the first power electrode A1, and the other end is conductively connected to the third power electrode A3 through the first control switch Q2, so that when the atomizer 1 is connected to the power supply 2, one end of the first control switch Q2 can be conductively connected to one electrode of the second battery cell 21 through the third power electrode A3 and the third power supply electrode B3, and the other end of the first control switch Q2 can be conductively connected to another electrode of the second battery cell 21 through the first heating element 121, the first power electrode A1, and the first power supply electrode B1. Therefore, after the atomizer 1 is connected to the power supply 2, the second battery cell 21 can provide a large amount of power to the first heating element 121 when the first control switch Q2 is triggered, so that the first heating element 121 atomizes the liquid matrix. When the first control switch Q2 includes a first puff detector, after the atomizer 1 is engaged with the power supply 2, the first puff detector can obtain power from the second battery cell 21 based on the second conductive path, and can be in a working state based on the power to detect whether the atomizer 1 is puffed. When the atomizer 1 is not puffed, the first heating element 121 obtains less power from the second battery cell 21, or can hardly obtain power from the second battery cell 21.

[0130] In an embodiment where the second battery cell 21 can also provide power to the first heating element 121, when the atomizer 1 is engaged with the power supply 2, the switching switch Q1 can be changed to the second state, or the state of the switching switch Q1 is changed so that the circuit between the first battery cell 11 and the first heating element 121 is disconnected, which can prevent the first battery cell 11 and the second battery cell 21 from discharging to the first heating element 121 at the same time when the atomizer 1 is engaged with the power supply 2.

[0131] For example, the formation of the second conductive path is mutually exclusive with the circuit conduction between the first battery cell 11 and the first heating element 121. Specifically, after the atomizer 1 is coupled with the power supply 2, the circuit between the first battery cell 11 and the first heating element 121 is disconnected, and at the same time, the second conductive path is formed.

[0132] For example, when the atomizer 1 is separated from the power supply 2, the first puff detector is conductively connected to the first battery cell 11, and the first battery cell 11 provides a working voltage for the first puff detector to detect the puff action, and when the atomizer 1 is connected to the power supply 2, the conductive connection between the first puff detector and the first battery cell 11 is disconnected, and the first puff detector is conductively connected to the second battery cell 21, and the second battery cell 21 provides a working voltage for the first puff detector to detect the puff action. This avoids the first battery cell 11 and the second battery cell 21 providing working voltages to the first puff detector at the same time and causing a conflict.

[0133] For example, when the atomizer 1 is separated from the power supply 2, the first puff detector is conductively connected to the first heating element 121 and the first battery cell 11, so that the first battery cell 11 can provide power to the first heating element 121 in response to the triggering of the first puff detector, so that the first heating element 121 can generate heat based on the power provided by the first battery cell 11 when the atomizer 1 is puffed; and when the atomizer 1 is connected to the power supply 2, the first puff detector is conductively connected to the first heating element 121 and the second battery cell 21, so that the second battery cell 21 can provide power to the first heating element 121 in response to the triggering of the first puff detector, so that the first heating element 121 can generate heat based on the power provided by the second battery cell 21 when the atomizer 1 is puffed. Avoid the conflict caused by the first battery cell 11 and the second battery cell 21 providing power for the first heating element 121 to generate heat at the same time.

[0134] In one embodiment of the present application, whether the atomizer assembly 12 includes one heating element or multiple heating elements, when the atomizer 1 has a first puff detector for detecting a puff action, when the atomizer 1 is separated from the power supply 2, the first puff detector is conductively connected to the first battery cell 11 to obtain a working voltage for detecting a puff action from the first battery cell 11; and when the atomizer 1 is coupled to the power supply 2, the conductive connection between the first battery cell 11 and the first battery cell 11 is disconnected, and the second battery cell 21 is conductively connected to obtain a working voltage for detecting a puff action from the second battery cell 21. Thus, when the atomizer 1 is separated from the power supply 2 and when the atomizer 1 is coupled to the power supply 2, the working voltage for the first puff detector to detect whether the atomizer 1 is puffed is provided by the first battery cell 11 and the second battery cell 21 respectively; when the atomizer 1 is coupled to the power supply 2, the second battery cell 21 can replace the first battery cell 11 to provide a working voltage for the first puff detector to detect whether the atomizer 1 is puffed.

[0135] In one embodiment of the present application, regardless of whether the atomizer assembly 12 includes one heating element or multiple heating elements, when the atomizer 1 has a first puff detector for detecting a puff action, the first puff detector conductively connects the atomizer assembly 12 and the first battery cell 11 when the atomizer 1 is separated from the power supply 2, so that the first battery cell 11 can provide power to the atomizer assembly 12 in response to the triggering of the first puff detector, so that at least one heating element in the atomizer assembly 12 can atomize the liquid matrix based on the power provided by the first battery cell 11; and when the atomizer 1 is engaged with the power supply 2, the atomizer assembly 12 is conductively connected to the second battery cell 21, so that the second battery cell 21 can provide power to the atomizer assembly 12 in response to the triggering of the first puff detector, so that at least one heating element in the atomizer assembly 12 can atomize the liquid matrix based on the power provided by the second battery cell 21.

[0136] In one embodiment of the present application, reference may be made to Figure 5-Figure 7 The first battery cell 11 is a rechargeable battery cell. When the atomizer 1 is connected to the power supply 2, the second battery cell 21 can charge and replenish the power and quantity of the first battery cell 11 through the first conductive path. For example, the atomizer 1 further includes a first charging interface A5 electrically connected to the first battery cell 11, and the power supply 2 further includes a charging terminal B5 electrically connected to the second battery cell 21. When the atomizer 1 is connected to the power supply 2, the charging terminal B5 is conductively connected to the first charging interface A5, so that the first conductive path is formed.

[0137] It should be noted that when the charging terminal B5 is conductively connected to the first charging interface A5, at least a portion of the charging terminal B5 can be inserted into the atomizer 1 and contact the first charging interface A5, but this is not limited to this. For example, when the charging terminal B5 is conductively connected to the first charging interface A5, at least a portion of the first charging interface A5 can be inserted into the power supply 2 and contact the charging terminal B5, or when the charging terminal B5 is conductively connected to the first charging interface A5, the first charging interface A5 and the charging terminal B5 are respectively located outside the power supply 2 and the atomizer 1, but the two are in contact with each other.

[0138] In such Figure 3 In the illustrated embodiment, at least a portion of the charging terminal B5 is columnar, fixed on the second base 24, and partially protrudes into the receiving cavity 231, so that when the atomizer 1 is engaged with the power supply 2, the charging terminal B5 can be inserted into the first charging interface A5.

[0139] In such Figure 6In the illustrated embodiment, the atomizer 1 has a first circuit board, on which a first charging circuit A6 is disposed, and the first charging circuit A6 is electrically connected to the first battery cell 11 and the first charging interface A5, for controlling and protecting the charging of the first battery cell 11. For example, the first charging circuit A6 can regulate the charging current, charging voltage and / or charging speed of the second battery cell 21 to the first battery cell 11. For example, the first charging circuit A6 can prevent the first battery cell 11 from being overcharged, and when the amount of electricity in the first battery cell 11 reaches a threshold, the first charging circuit A6 can automatically disconnect the electrical connection between the first battery cell 11 and the first charging interface A5, thereby preventing the first battery cell 11 from continuing to be charged. For example, the first charging circuit A6 can monitor the remaining power of the first battery cell 11. When the remaining power in the first battery cell 11 is lower than a threshold value, the first charging circuit A6 can control a sensory prompter such as a light, a player or a motor to generate a sensory prompt signal to prompt the user that the power of the first battery cell 11 is too low, or when the remaining power in the first battery cell 11 is lower than a threshold value, the first charging circuit A6 can automatically cut off the conductive connection between the first battery cell 11 and the atomization assembly 12 to prevent the first battery cell 11 from continuing to discharge.

[0140] In such Figure 5-Figure 8 In the illustrated embodiment, the power supply 2 has a second circuit board, on which a second charging circuit B6 is disposed. The second charging circuit B6 is electrically connected to the second battery cell 21 and the charging terminal B5, and is used for performing discharge control and discharge protection on the second battery cell 21 when the second battery cell 21 charges the first battery cell 11.

[0141] For example, the second charging circuit B6 can monitor the remaining power of the second battery cell 21, and can control the discharge power of the second battery cell 21 to the first battery cell 11 based on the remaining power of the second battery cell 21, so as to prevent the remaining power in the second battery cell 21 from being too low, thereby protecting the second battery cell 21. In some examples, when the remaining power in the second battery cell 21 is lower than a threshold value, the second charging circuit B6 can control a sensory prompter such as a light, a player, or a motor to generate a sensory prompt signal to prompt the user that the power of the second battery cell 21 is too low, or when the remaining power in the second battery cell 21 is lower than a threshold value, the second conductive path is automatically cut off to prevent the second battery cell 21 from continuing to discharge.

[0142] Furthermore, when the charging terminal B5 is electrically connected to the first charging interface A5, the second charging circuit B6 can obtain the power required for charging the first battery cell 11 or the remaining power of the first battery cell 11, and form or call the discharge strategy of the second battery cell 21 based on the remaining power of the second battery cell 21. In some examples, when the power of the second battery cell 21 is lower than the maximum power reserve of the first battery cell 11 or lower than the power required for charging the first battery cell 11, the second charging circuit B6 automatically disconnects the electrical connection between the second battery cell 21 and the charging terminal B5 to prohibit the second battery cell 21 from charging the first battery cell 11, so that the second battery cell 21 preferentially provides power for the atomization assembly 12 to atomize the liquid matrix to meet the user's need to continue inhaling. In some examples, when the charge in the second battery cell 21 is lower than a threshold value, but the charge in the first battery cell 11 is relatively sufficient, the second charging circuit B6 controls the trigger mechanism 22 to release the trigger on the switching switch Q1 or adjust the trigger on the switching switch Q1, so that the switching switch Q1 returns to the first state, so that the first battery cell 11 replaces the second battery cell 21 to provide power for the atomization assembly 12 to atomize the liquid matrix.

[0143] For example, the second charging circuit B6 can control the second battery cell 21 to charge the first battery cell 11 while the second battery cell 21 provides power to the atomizer assembly 12 so that the atomizer assembly 12 atomizes the liquid matrix, so that the first battery cell 11 therein can also be charged while the atomizer 1 is being inhaled; further, the second charging circuit B6 can also allocate the power used by the second battery cell 21 to charge the first battery cell 11 and the power used by the second battery cell 21 to provide power to the atomizer assembly 12 based on the remaining power of the second battery cell 21. For example, the power of the first battery cell 11 charged by the second battery cell 21 and the power of the atomizer assembly 12 are allocated based on the power of the atomizer assembly 12 and the power of the second battery cell 21 to provide power to the atomizer assembly 12, by the sum of the remaining power of the first battery cell 11 and the remaining power of the second battery cell 21, or by the sum of the discharge power of the first battery cell 11 and the discharge power of the second battery cell 21, so that under the current sum of the remaining power or the sum of the discharged power, the total time of the atomizer assembly 12 atomizing the liquid matrix can be maximized, thereby allowing the user to have a longer inhalation time.

[0144] In such Figure 5 and Figure 7 In the embodiment shown, the first charging circuit A6 is integrated on the second circuit board, and thus is a component of the second charging circuit B6 or a component of the power supply 2, thereby reducing the cost of the atomizer 1. In this embodiment, the atomizer 1 does not have a charging circuit.

[0145] In such Figure 4-Figure 8In the illustrated embodiment, the second battery cell 21 is a rechargeable battery cell, and the power supply 2 further includes a second charging interface B7 for electrically connecting to a charger, the second charging interface B7 is electrically connected to the second battery cell 21, and the charger charges the second battery cell 21 through the second charging interface B7. The charger may be a portable charger having a battery cell, or may be a charger for connecting the mains power to the power supply so that the mains power can charge the second battery cell 21 in the power supply through the charger.

[0146] The second charging circuit B6 is electrically connected to the second battery cell 21 and the second charging interface B7, and the second charging circuit B6 can control the charging of the second battery cell 21 and protect the charging of the second battery cell 21. For example, the second charging circuit B6 can regulate the charging current, charging voltage and / or charging speed of the second battery cell 21. For example, the second charging circuit B6 can prevent the second battery cell 21 from being overcharged, and when the power in the second battery cell 21 reaches a threshold, the electrical connection between the second battery cell 21 and the second charging interface B7 can be automatically disconnected, thereby preventing the second battery cell 21 from continuing to be charged. For example, the second charging circuit B6 can monitor the remaining power of the second battery cell 21. When the remaining power in the second battery cell 21 is lower than the threshold, the second charging circuit B6 can control a sensory prompter such as a light, a player or a motor to generate a sensory prompt signal to prompt the user that the power of the second battery cell 21 is too low, or when the remaining power in the second battery cell 21 is lower than the threshold, the second conductive path is automatically cut off to prevent the second battery cell 21 from continuing to discharge.

[0147] In one embodiment, reference may be made to Figure 8 , the second control switch Q3 is electrically connected to the second charging interface B7 and the second battery cell 21 , and when the second control switch Q3 is not triggered, the second charging interface B7 and the second battery cell 21 are electrically connected.

[0148] In this embodiment, the second control switch Q3 can be a second puff detector, and the second control switch Q3 can be triggered only when the second puff detector detects puffing. After the atomizer 1 is engaged with the power supply 2 or after the second conductive path is formed, the second puff detector is connected to the atomizer 1 because of the airflow. When the nozzle 13 of the atomizer 1 is sucked, it can cause the airflow or air pressure near the second puff detector to change, thereby being able to detect whether the atomizer 1 is sucked and causing the second control switch Q3 to be triggered. Before the atomizer 1 is engaged with the power supply 2 or before the second conductive path is formed, because the user cannot suck the power supply 2, the second control switch Q3 remains untriggered, so the second charging interface B7 and the second battery cell 21 remain electrically connected, and the power supply 2 can be charged.

[0149] The second control switch Q3 can be triggered only after the atomizer 1 is connected to the power supply 2 or after the second conductive path is formed. Therefore, before the atomizer 1 is connected to the power supply 2 or before the second conductive path is formed, the second control switch Q3 remains untriggered, and the second charging interface B7 and the second battery cell 21 remain electrically connected, so the power supply 2 can be charged.

[0150] In some embodiments, after the atomizer 1 is connected to the power supply 2 or after the second conductive path is formed, and when the first control switch Q2 is triggered, the second control switch Q3 is triggered. Therefore, after the atomizer 1 is connected to the power supply 2 or after the second conductive path is formed, but when the first control switch Q2 is not triggered or when the second control switch Q3 is not triggered, the second charging interface and the second battery 21 are electrically connected, so the power supply 2 can be charged. Based on this, when the second battery 21 provides power to the atomizer assembly 12 through the second conductive path, the electrical connection between the second charging interface B7 and the second battery 21 is disconnected, and the second battery 21 cannot be charged. When the second conductive path is formed, but the atomizer assembly 12 does not atomize the liquid matrix based on the power of the second battery 21, the second charging interface B7 and the second battery 21 are electrically connected, so the power supply 2 can be charged. Therefore, after the atomizer 1 is connected to the power supply 2, the power supply 2 and the charger are electrically connected, and the charger can charge the second battery 21 during the user's puff interval.

[0151] It should be noted that the first charging interface A5 can be electrically connected to a charger, so that the first battery cell 11 can also be charged by the charger.

[0152] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
