DETAILED DESCRIPTION

[0029] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0031] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0032] In one embodiment, the aerosol generating device includes an atomizer (not shown) and a power supply for supplying power to the atomizer. The atomizer includes a heating element (not shown) for heating the aerosol generating substrate.

[0033] The structure of the atomizer is well-established in the art and will not be further described in the examples of this application. In one embodiment, the atomizer uses an aerosol-generating oil (e.g., tobacco oil) to generate the aerosol. In some other embodiments, the atomizer uses an aerosol-generating rod (e.g., a cigarette stick) to generate the aerosol.

[0034] The power supply device includes a housing 1, a power supply 2, and a device circuit (not shown). The power supply 2 is used to supply power to the heating element of the aerosol generating device, and the device circuit is used to connect or disconnect the power supply 2 and the heating element. The power supply device also includes a power button 3, a voltage adjustment button 4, and a mode switch button 5. The device circuit turns the power supply 2 on and off in response to the power button, and adjusts the heating power of the heating element in response to the voltage adjustment button 4. The mode switch button 5 has a first position and a second position. When the mode switch button 5 is in the first position, the voltage adjustment button 4 is locked, and when the mode switch button 5 is in the second position, the voltage adjustment button 4 is unlocked. Specifically, the power button 3 and the voltage adjustment button 4 are both disposed on the housing 1.

[0035] The locking or unlocking of the voltage regulating key 4 described in the present application includes both the situation that the mode conversion key 5 directly locks or unlocks the voltage regulating key 4 through a mechanical structure, and the situation that the mode conversion key 5 gives a signal, and the device circuit locks or unlocks the voltage regulating key 4 in response to the signal. That is, the device circuit locks or unlocks the voltage regulating key 4 in response to the gear position of the mode conversion key 5. As for the response method of the device circuit, any feasible method can be adopted. For example, there is a control circuit in the device circuit, and the control circuit controls whether the voltage regulating key 4 is connected to the device circuit according to the signal given by the mode conversion key 5. If the mode conversion key 5 is in the first gear, the control circuit locks the voltage regulating key 4 according to the received signal. At this time, the voltage regulating key 4 is not connected to the device circuit, and the heating power of the heating element cannot be adjusted by operating the voltage regulating key 4. For another example, the mode conversion key 5 can operate the control switch, and the voltage regulating key 4 can be disconnected or connected to the device circuit by operating the control switch.

[0036] The device circuit in this application can adopt any feasible circuit in the prior art. For example, the device circuit includes a control circuit and a power supply circuit, wherein the power supply circuit is used to conduct power between the power supply 2 and the heating element, and the control circuit is used to control the on and off of the power supply circuit, thereby controlling the on and off between the power supply 2 and the heating element. At the same time, the control circuit can also control the heating power of the heating element.

[0037] Furthermore, in one embodiment, the mode switch key 5 has a third position. When the mode switch key 5 is in the third position, the power key 3 and the pressure adjustment key 4 are locked. When the mode switch key 5 is in the first position and the second position, the power key 3 is unlocked. In this state, the power supply 2 can be turned on and off normally by operating the power key 3. In the third position, both the power key 3 and the pressure adjustment key 4 can be locked, thereby preventing accidental activation of the power key 3 and the pressure adjustment key 4 when the aerosol generating device is not in use. In some other embodiments, the mode switch key 5 may have only the first and second positions.

[0038] Furthermore, in one embodiment, regarding the shifting mode of the mode switch key 5, the mode switch key 5 is movably disposed on the housing 1, and the mode switch key 5 achieves shifting by changing its position on the housing 1. Compared to shifting by adjusting the position of the mode switch key 5 by touch, the operation is simpler and more intuitive. In some other embodiments, the mode switch key 5 may also be a touch key.

[0039] The mode switch key 5 and the housing 1 can be mounted in any suitable manner. For example, the mode switch key 5 can be movably mounted on the housing 1 or rotatably mounted on the housing 1. Specifically, regarding the movement of the mode switch key 5, the mode switch key 5 can be mounted on the housing 1 in a linear manner. This makes operation of the mode switch key 5 more convenient.

[0040] Specifically, in one embodiment, a magnet 6 is disposed on the mode switch key 5, and the power supply module includes a magnetic sensing unit 7. The magnetic sensing unit 7 is used to sense the position of the magnet 6. Specifically, the magnet 6 can be mounted on the mode switch key 5 by bonding, welding, embedding, or the like.

[0041] When the mode conversion key 5 moves to the first gear, the device circuit locks the voltage adjustment key 4 in response to the sensing result of the magnetic induction unit 7. When the mode conversion key 5 is in the second gear, the device circuit unlocks the voltage adjustment key 4 in response to the sensing signal of the magnetic induction unit 7.

[0042] There are many feasible ways for the device circuit to respond to the sensing results of the magnetic induction unit 7. For example, the device circuit includes a control circuit and a circuit switch. After the control circuit receives the signal from the magnetic induction unit 7, it controls the circuit switch to be on and off, thereby realizing the on and off of the circuit between the power supply 2 and the heating element.

[0043] Specifically, when the mode conversion key 5 is in the third gear, the power button 3 is locked and the voltage adjustment key 4 is locked. When the mode conversion key 5 is in the first gear and the second gear, the power button 3 is unlocked. The number of magnetic induction units 7 is at least two, at least one magnetic induction unit 7 is a first magnetic induction unit 71, and at least one magnetic induction unit 7 is a second magnetic induction unit 72. The magnet 6 cooperates with the first magnetic induction unit 71 to lock and unlock the voltage adjustment key 4, and the magnet 6 cooperates with the second magnetic induction unit 72 to lock and unlock the power button 3. In the direction of movement of the mode conversion key 5, the first gear is between the second gear and the third gear. When the mode conversion key 5 is in the second gear, the first magnetic induction unit 71 can sense the magnet 6 and generate an electrical signal, and the second magnetic induction unit 72 cannot sense the magnet 6. The power button 3 and the voltage adjustment key 4 are both in the unlocked state.

[0044] When the mode switch key 5 is in the third position, the second magnetic sensing unit 72 can sense the magnet 6 and generate an electrical signal, while the first magnetic sensing unit 71 cannot sense the magnet 6, and the power button 3 and the voltage adjustment key 4 are both locked. When the mode switch key 5 is in the first position, the first magnetic sensing unit 71 and the second magnetic sensing unit 72 cannot sense the magnet 6, causing the voltage adjustment key 4 to be locked and the power button 3 to be unlocked.

[0045] The above-mentioned induction form of the magnetic induction unit 7 and the magnet 6 is only an example. In some other embodiments, when the mode conversion key 5 is in the second gear, the first magnetic induction unit 71 can also be configured to be unable to sense the magnet 6, and the second magnetic induction unit 72 can sense the magnet 6 and generate an electrical signal; in some other embodiments, when the mode conversion key 5 is in the third gear, the second magnetic induction unit 72 can also be configured to be unable to sense the magnet 6, and the first magnetic induction unit 71 can sense the magnet 6 and generate an electrical signal.

[0046] The voltage adjustment key 4 is in the normally locked position. The first magnetic sensing unit 71 cannot sense the magnet 6 when the mode conversion key 5 is in the first gear and the third gear, and cannot generate an induction signal to sense the magnet 6. The first magnetic sensing unit 71 can only sense the magnet 6 when the mode conversion key 5 is in the second gear. Only after the first magnetic sensing unit 71 senses the magnet 6 and generates an induction signal, the voltage adjustment key 4 is unlocked.

[0047] The power button 3 is in the normally unlocked position. The second magnetic sensing unit 72 cannot sense the magnet 6 when the mode conversion button 5 is in the first gear and the second gear, and cannot generate an induction signal to sense the magnet 6. The second magnetic sensing unit 72 can sense the magnet 6 when the mode conversion button 5 is in the third gear. Only after the second magnetic sensing unit 72 senses the magnet 6 and generates an induction signal, the power button 3 is locked.

[0048] In one embodiment, the magnetic induction unit 7 utilizes a Hall switch. Specifically, there are two magnetic induction units 7, one of which is a first magnetic induction unit 71 and the other is a second magnetic induction unit 72. In one embodiment, the power supply device includes a circuit board 8, and at least a portion of the device circuit is located on the circuit board 8. In one embodiment, the magnetic induction unit 7 is mounted on the circuit board 8.

[0049] Regarding the structure of the mode switch key 5, the mode switch key 5 comprises a key body 51 and a keycap 52. The key body 51 is mounted on the outer shell 1, and the keycap 52 is fixed to the key body 51. Specifically, in one embodiment, the outer shell 1 comprises an inner shell 11 and an outer shell 12. The inner shell 11 has a key body mounting slot 111, in which the key body 51 is movably disposed. The outer shell 12 has a keycap mounting hole 121, in which the keycap 52 is disposed. The keycap 52 is longer than the key body 51 and covers the notch of the key body mounting slot 111. This allows a portion of the keycap 52 to extend out of the keycap mounting hole 121, while another portion remains between the inner shell 11 and the outer shell 12. This prevents the keycap 52 from being lost and limits its movement, improving the smoothness of the mode switch key 5. In some other embodiments, the mode switch key 5 can be integrally formed, with the magnet embedded within the switch key.

[0050] Furthermore, to maintain the position of the key body 51, one of the key body 51 and the housing 1 has a protrusion 511, and the other has a latching slot 13. The protrusion 511 can be snapped into the latching slot 13 to maintain the position of the mode switch key 5. In one embodiment, the protrusion 511 is on the key body 51, and the latching slot 13 is on the housing 1. Since the mode switch key 5 has three positions, in one embodiment, there are three latching slots 13.

[0051] Specifically, the key body 51 has a clamping block 512 , and the key cap 52 has a clamping hole 521 . The clamping block 512 is clamped into the clamping hole 521 to achieve assembly of the key body 51 and the key cap 52 .

[0052] Based on the above analysis, when the user does not need to use the voltage adjustment function and needs to turn the power on and off (for example, the user has adjusted the heating power of the heating element and does not need to adjust it later), the operation mode conversion key 5 is in the first gear, and the first magnetic induction unit 71 and the second magnetic induction unit 72 cannot sense the magnet 6. At this time, the voltage adjustment key 4 is locked and the power key 3 is in the unlocked state.

[0053] When the user needs to use the voltage adjustment function and also needs to turn the power on and off, the operation mode conversion key 5 is in the second gear, the first magnetic induction unit 71 can sense the magnet 6 and generate an electrical signal, and the second magnetic induction unit 72 cannot sense the magnet 6. At this time, the voltage adjustment key 4 and the power key 3 are both in the unlocked state.

[0054] When the user does not need to use the voltage adjustment function and does not need to turn the power on or off (for example, when the aerosol generating device is being transported or is temporarily no longer in use after use), the operation mode switch 5 is in the third position. The second magnetic sensing unit 72 can sense the magnet 6 and generate an electrical signal, while the first magnetic sensing unit 71 cannot sense the magnet 6. At this time, the voltage adjustment key 4 and the power key 3 are both locked.

[0055] The magnet 6 cooperates with the first magnetic sensing unit 71 to lock and unlock the voltage adjustment key 4, and the magnet 6 cooperates with the second magnetic sensing unit 72 to lock and unlock the power key 3. In the direction of movement of the mode switch key 5, the first gear is between the second gear and the third gear. When the mode switch key 5 is in the second gear, the second magnetic sensing unit 72 cannot sense the magnet 6. When the mode switch key 5 is in the third gear, the first magnetic sensing unit 71 cannot sense the magnet 6. When the mode switch key 5 is in the first gear, neither the first magnetic sensing unit 71 nor the second magnetic sensing unit 72 can sense the magnet 6.

[0056] In one embodiment, the locking and unlocking of the power button 3 and the voltage adjustment button 4 are both controlled by the control circuit. When a button is locked by the control circuit, pressing that button does not perform the corresponding function. For example, when the power button 3 is locked, operating the power button 3 does not turn the power on or off. Similarly, when the voltage adjustment button 4 is locked, operating the voltage adjustment button 4 does not adjust the heating power of the heating element.

[0057] In some other embodiments, locking and unlocking of the power key and the voltage adjustment key may also be achieved through a mechanical structure.

[0058] In one embodiment, the housing 1 includes a power supply compartment, and the power supply 2 is located in the power supply compartment. Specifically, the power supply is a battery. To facilitate removal of the battery, the housing 1 includes a flip cover 14. By opening the flip cover 14, the battery can be loaded or removed.

[0059] In an embodiment of a power supply device for an aerosol generating device, the power supply device has the same structure as the power supply device described in any of the above embodiments and will not be described in detail.

[0060] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
