In this embodiment, in the specific implementation, the first electric heating portion 141 may be any one of a metal electric heating wire, a metal electric heating sheet, a metal electric heating net, a conductive ceramic electric heating sheet, and a conductive ceramic electric heating net, that is, the first electric heating portion 141 may be an electric heating wire, an electric heating sheet, or an electric heating net made of a metal material, or may be an electric heating sheet or an electric heating net made of a conductive ceramic material, and of course, the first electric heating portion 141 may also be other types of electric heating structures, as long as the atomized liquid adsorbed at the connection portion between the porous medium 13 and the first electric heating portion 141 can be vaporized into vapor that can be absorbed by a user, which is not limited in this embodiment. Similarly, the second electric heating portion 142 may be any of a metal heating wire, a metal heating sheet, a metal heating mesh, and a conductive ceramic, so long as the atomized liquid adsorbed at the connection portion between the porous medium 13 and the second electric heating portion 142 can be vaporized into an aerosol for the user to inhale, which is not particularly limited in this embodiment.

In this embodiment, in a specific implementation, in some alternative embodiments, the first connection end 113 of the first housing 11 may be a shaft structure, correspondingly, the second connection end 211 of the second housing 21 may be a hole structure, in other alternative embodiments, the first connection end 113 of the first housing 11 may also be a hole structure, correspondingly, the second connection end 211 of the second housing 21 may be a shaft structure, so long as the first connection end 113 of the first housing 11 and the second connection end 211 of the second housing 21 can be movably inserted into each other, which is not limited in particular, as shown in fig. 2-7, for example, the first connection end 113 of the first housing 11 is a shaft structure, the second connection end 211 of the second housing 21 is a hole structure, specifically, the first electrode 121, the second electrode 122 and the third electrode 123 are disposed on an end face of the first connection end 113, the second connection end 211 is provided with a cavity capable of accommodating the first connection end 113, and the second connection end 23 is disposed in the first housing 2110, and the first housing 2110 is capable of being axially inserted into the first housing 11, and the second housing 2110 is configured to accommodate at least one of the first connection end portion 11, and the first housing 2110 is configured to be axially inserted into the first housing 11, so that the first housing 11 is axially compatible with the first housing 2110.

For example, when the first connection end 113 of the atomizer 1 is in a cylindrical structure as a whole, after the atomizer 1 and the power supply assembly 2 are integrally plugged, the atomizer 1 can rotate relative to the power supply assembly 2 along the circumferential direction of the power supply assembly 2, and can also move relative to the power supply assembly 2 along the axial direction of the power supply assembly 2, and further when the orientation state of the atomizer 1 needs to be adjusted from the first orientation to the second orientation or from the second orientation to the first orientation, so as to realize the mutual switching between the first electric heating portion 141 and the second electric heating portion 142, only the atomizer 1 needs to be rotated by a certain angle relative to the power supply assembly 2, so that the corresponding electrode is switched. For another example, when the first connection end 113 of the atomizer 1 is in a linear edge shape (e.g., a square block shape, a cross section of which is in a "racetrack shape") and the atomizer 1 and the power supply unit 2 are integrally inserted, the atomizer 1 can only move relative to the power supply unit 2 in the axial direction of the power supply unit 2, and therefore, in this case, when the orientation state of the atomizer 1 needs to be adjusted from the first orientation to the second orientation or from the second orientation to the first orientation, the mutual switching between the first electric heating portion 141 and the second electric heating portion 142 can be achieved only by "pulling out the atomizer 1 first, rotating the atomizer 1 by a certain angle, and then reinserting the first connection end 113 of the atomizer 1 into the housing 2110 of the power supply unit 2".

In the present embodiment, it is understood that the first electrode 121, the second electrode 122, the third electrode 123, the fourth electrode 231, and the fifth electrode 232 are all made of conductive materials, for example, pure metal materials (e.g., gold, silver, aluminum, copper, iron, nickel, titanium, etc.) or alloy materials (e.g., gold alloy, silver alloy, aluminum alloy, copper alloy, nickel alloy, stainless steel, etc.), as long as the use requirements are satisfied, which is not particularly limited in the present embodiment. In some application scenarios, the fourth electrode 231 may be used as the negative electrode of the power supply assembly 2, the fifth electrode 232 may be used as the positive electrode of the power supply assembly 2, and accordingly, the first electrode 121 and the third electrode 123 may be used as the negative electrode of the atomizer 1, and the second electrode 122 may be used as the positive electrode of the atomizer 1.

In the present embodiment, it can be understood that, in some specific application scenarios, the battery module 22 may be configured as a lithium battery, a dry battery, or other type of power supply; in other specific application scenarios, the battery module 22 may include a control circuit board and a power supply, where the control circuit board is electrically connected to the power supply, the fourth electrode 231 and the fifth electrode 232, and the control circuit board may control the power supply to supply power to the fourth electrode 231 and the fifth electrode 232 or control the power supply to stop supplying power to the fourth electrode 231 and the fifth electrode 232, so as to control the first electric heating portion 141 or the second electric heating portion 142 to perform power-on operation or power-off operation.

Based on the above structural design, the use principle of the electronic atomization device of the embodiment is as follows:

referring to fig. 2-7, when the nebulizer 1 needs to be plugged into the power supply assembly 2 in the first orientation, after the first electrode 121 of the nebulizer 1 is aligned with the fourth electrode 231 of the power supply assembly 2 and the second electrode 122 of the nebulizer 1 is aligned with the fifth electrode 232 of the power supply assembly 2, the first connection end 113 of the nebulizer 1 is inserted into the accommodating cavity 2110 of the power supply assembly 2, so that the first electrode 121 is electrically contacted with the fourth electrode 231, the second electrode 122 is electrically contacted with the fifth electrode 232, and the first electric heating portion 141 can be connected with the battery module 22 to be electrified and heated, when the first electric heating portion 141 is electrified and heated, atomized liquid provided by the porous medium 13 is vaporized into vapor, which can be discharged to the outside through the air outlet of the air flow channel 111 and sucked by a user, and at this time, the second electric heating portion 142 is not connected with the battery module 22, so that the second electric heating portion 142 is not electrified and operated;

when the nebulizer 1 needs to be plugged into the power supply assembly 2 in the second orientation, the first connection end 113 of the nebulizer 1 is pulled out of the housing 2110 of the power supply assembly 2 along the axial direction of the power supply assembly 2, then the nebulizer 1 is rotated by a certain angle (e.g. 180 °) so that the third electrode 123 of the nebulizer 1 is aligned with the fourth electrode 231 of the power supply assembly 2 and the second electrode 122 of the nebulizer 1 is aligned with the fifth electrode 232 of the power supply assembly 2, then the first connection end 113 of the nebulizer 1 is inserted into the housing 2110 of the power supply assembly 2, so that the third electrode 123 is in electrical contact with the fourth electrode 231 and the second electrode 122 is in electrical contact with the fifth electrode 232, thereby the second electric heating portion 142 can be powered on to generate heat, when the second electric heating portion 142 is powered on, the nebulized liquid provided by the porous medium 13 is vaporized into vapor, the vapor can be discharged to the outside through the air outlet of the air flow channel 111 at this time and sucked by the user, and the first electric heating portion 141 is not powered on by the battery module 22.

In the technical solution of this embodiment, since the electrothermal member 14 in the atomizer 1 includes the first electric heating portion and the second electric heating portion 142, the atomizer 1 can be respectively located in the first orientation and the second orientation with different orientations along the circumferential direction of the power supply assembly 2, and when the atomizer 1 is plugged into the power supply assembly 2 in the first orientation, the first electric heating portion 141 is connected to the battery module 22 of the power supply assembly 2 and the second electric heating portion 142 is not connected to the battery module 22, so that only the first electric heating portion 141 in the electrothermal member 14 is powered on in this situation, and when the atomizer 1 is plugged into the power supply assembly 2 in the second orientation, the second electric heating portion 142 is connected to the battery module 22 and the first electric heating portion 141 is not connected to the battery module 22, so that only the second electric heating portion 142 in the electrothermal member 14 is powered on, that is, whether the atomizer 1 is plugged into the power supply assembly 2 in the first orientation or plugged into the power supply assembly 2 in the second orientation, the first electric heating part 141 and the second electric heating part 142 in the electric heating element 14 are always not simultaneously electrified and work, but only one of the electric heating parts is electrified and work, so that the electric heating element 14 is not always electrified and work at full power, the risk of burning of the electric heating element 14 can be effectively reduced, and the first electric heating part 141 and the second electric heating part 142 in the electric heating element 14 can be respectively electrified and work independently when the atomizer 1 is in different orientation states, so that even if one of the first electric heating part 141 and the second electric heating part 142 is burnt out, the atomizer 1 can still be continuously used by changing the orientation state of the atomizer, for example, when the first electric heating part 141 is burnt out, although the atomizer 1 cannot be plugged into the power supply assembly 2 in the first orientation, however, the atomizer 1 can still be plugged into the power supply assembly 2 in the second direction, that is, when the first electric heating portion 141 burns out, the atomizer 1 can be continuously used only by adjusting the direction state of the atomizer 1 relative to the power supply assembly 2 from the first direction to the second direction, so that the service life of the atomizer 1 can be effectively prolonged.
