Specifically, the mounting seat is provided with a first support and a second support, the first support and the second support are both arranged in the first mounting cavity, and the first support is positioned on one side of the second support, which is close to the liquid storage cavity; the first support and the second support are matched to form an atomization cavity. The second groove 122 is disposed at an end of the second support away from the first support. The number of the second grooves 122 may be one or more than one, and in this embodiment, the number of the second grooves 122 is two.

The atomizer 12 further comprises an identifier 121, the identifier 121 being arranged in the second recess 122. Accordingly, the number of the identification members 121 may be one or more than one. The number of the identification members 121 is two in this embodiment. The material of the identifier 121 may be at least one of sendust, ferrite, mn-zn ferrite, and ni-zn ferrite. It is understood that the above materials are all common inductance core materials, and in other embodiments, other magnetic core materials, such as magnetic powder cores (iron powder cores, etc.), may also be used.

Referring to fig. 1 and 2, a battery assembly 13 for use in the electronic atomizer 10 is also provided. The battery assembly 13 includes a battery support, a battery, an inductor 133, and a main circuit board 134. The battery holder has a third recess 132 at an end thereof adjacent to the atomizer 12, wherein an inductor 133 is disposed in the third recess 132. The battery support has a second mounting cavity in which the main circuit board 134 and the battery are assembled, and the main circuit board 134 is disposed on one side of the second mounting cavity close to the atomizer 12.

Specifically, fig. 2 provides a schematic structural diagram of a connection manner between the inductor 133 and the main circuit board 134, the third groove 132 penetrates through the battery holder to communicate the second mounting cavity with the outside of the battery holder, two ends of the coil 1332 of the inductor 133 extend out of one end of the third groove 132 away from the atomizer 12 and are connected with the main circuit board 134, and the connection manner may be, but is not limited to, welding. The main Circuit board 134 may be, but is not limited to, a PCB (Printed Circuit Boards).

The main circuit board 134 includes a capacitor 1341 and a main control circuit 1342, and the capacitor 1341 is connected in parallel with the inductor 133 of the battery assembly 13 to form an LC oscillating circuit. The identification member 121 having specific parameters in the nebulizer 12 enables the inductance value of the inductor 133 in the LC oscillation circuit to be changed to a preset inductance value. Specifically, when the atomizer 12 is mounted on the battery pack 13, the identification member 121 having specific parameters affects and changes the inductance value of the inductor 133, thereby changing the oscillation signal, such as the oscillation frequency, of the LC oscillation circuit; in this embodiment, the oscillation frequency is taken as an example, and the calculation formula of the oscillation frequency is:

(f is the oscillation frequency, L is the inductance, and C is the value of capacitor 1341); from the calculation formula of the inductance value:

(L is an inductance value, S is a cross-sectional area of the core, N is the number of turns of the coil 1332, L is a magnetic path length of the core, and ui is a magnetic permeability of the core). As can be seen, the magnetic permeability, shape, and material of the identifier 121 differ, the influence on the inductance value differs, and the influence on the oscillation frequency differs. Therefore, the identification part 121 has specific parameters, so that the inductance value can be changed to a preset inductance value. Wherein the specific parameter is at least one or more of a cross-sectional area S of the core, a magnetic path length l of the core, and a magnetic permeability ui of the core. The identification element 121 of a specific parameter corresponds to an oscillation frequency, and changing the specific parameter of the identification element 121 will cause the inductance value to change, as will the oscillation frequency of the LC oscillation circuit. A manufacturer may detect the oscillation frequency of the LC oscillation circuit corresponding to the influence of the identifier 121 of the specific parameter in the batch of electronic atomization devices 10 before shipment, and sum the oscillation frequency values as a preset oscillation frequency value. The master control circuit 1342 can control the connection mode of the circuit of the battery pack 13 and/or the nebulizer 12 according to the change in the oscillation signal. When the atomizer 12 is incorporated in the battery pack 13, an oscillation signal of the LC oscillation circuit is generatedAlternatively, the master control circuit 1342 can detect the oscillation frequency and control the connection mode of the circuitry of the battery assembly 13 and/or the atomizer 12 based on the oscillation frequency.

Specifically, in the anti-counterfeit identification mode, the main control circuit 1342 can control the connection and disconnection of the circuit between the battery assembly 13 and the atomizer 12 according to the change of the oscillation signal; when the oscillation frequency falls within the preset oscillation frequency range, the atomizer 12 can be determined as a genuine product, and the circuit between the battery assembly 13 and the atomizer 12 is connected, so that the user can use the electronic atomization device 10. When the oscillation frequency value does not fall within the preset oscillation frequency range, the main control circuit 1342 determines that the atomizer 12 is a counterfeit product, and disconnects the circuit between the battery assembly 13 and the atomizer 12, so that the user cannot use the electronic atomization device 10.

In the flavor recognition mode, the main control circuit 1342 can control the heating temperature of the heating circuit of the atomizer 12 according to the change of the oscillation signal. For example, when the oscillation frequency value is a preset oscillation frequency value, the taste type of the atomizer 12 can be determined, and the main control circuit controls the heating temperature of the heating circuit of the atomizer 12 according to the taste type, so that the atomizers 12 with different tastes atomize at different heating temperatures, and a user has better use experience.

In the smoke concentration recognition mode, the main control circuit 1342 can control the heating power of the heating circuit of the atomizer 12 according to the change of the oscillation signal. When the oscillation frequency value is a certain preset oscillation frequency value, the smoke concentration type of the atomizer 12 can be judged, and the main control circuit controls the heating power of the heating circuit of the atomizer 12 according to the smoke concentration type, so that the atomizers 12 of different smoke types can atomize by using different heating powers, and a user has better use experience. In other embodiments, the electronic atomizer 10 may have other identification modes, not limited to the identification mode described above.

It is understood that in some embodiments, the anti-counterfeiting identification, the taste identification, the smoke concentration identification and other modes can be realized in a single functional mode, or at least two functional modes can be combined. Namely, on the basis of realizing the anti-counterfeiting identification mode, the taste identification mode and/or the smoke concentration identification mode can be realized in a superposition mode. The electronic atomization device 10, the atomizer 12 and the battery pack 13 are provided with the LC oscillating circuit and the main control circuit 1342 in the battery pack 13, so that the battery pack 13 can control the use mode of the electronic atomization device 10 by determining whether the inserted atomizer 12 can change the oscillating signal of the LC oscillating circuit into a preset oscillating signal, so as to achieve the identification of the electronic atomization device 10. The atomizer 12 and the battery pack 13 in the electronic atomization device 10 do not need to be provided with identification chips, so that a good identification effect can be realized, the cost is low, the structure is simple, and the production and the manufacture are convenient.

In this embodiment, a portion of the identification member 121 serves as a magnetic core of the inductor 133. When the atomizer 12 is mounted in the battery pack 13, the identifier 121 having specific parameters is inserted into the coil 1332, and the inductance value of the inductor 133 is changed to a predetermined inductance value, so that the oscillation signal of the LC oscillation circuit can be changed to a predetermined oscillation signal. The material of the identification element 121 may be a conventional inductive core material, such as a ferrite material. The inductor 133 with such a structure has a simple structure, and directly uses the part of the identifier 121 in the atomizer 12 as the magnetic core of the coil 1332, so that the electronic atomization device 10 has low cost and a simple and convenient manufacturing process.

The material of the magnetic core 1331 may be a common inductance core material, such as at least one of sendust, ferrite, mn-zn ferrite, and ni-zn ferrite, and other magnetic core materials, such as a magnetic powder core (iron powder core, etc.), may also be used.

When the inductor 133 is installed, a boss is disposed on the inner surface of the third groove 132, and the edge 13315 of the base 13314 may be disposed on the boss to form a limiting structure, so that the inductor 133 can be fixed in the third groove 132. The inductor 133 has a simple structure and is easy and convenient to install.

The magnetic core 1331 may further include a first groove 13316 and a protruding pillar 13317, the protruding pillar 13317 is protruded at the bottom of the first groove 13316 and extends to the notch of the first groove 13316, and the coil 1332 is disposed in the first groove 13316 and spirally sleeved on the protruding pillar 13317.

Specifically, the protruding pillar 13317 is a hollow cylinder and has a notch on a side wall thereof, so as to form a first groove 13316. In other embodiments, the protruding pillar 13317 may not have the slot 13318 thereon, and one end of the coil 1332 near the bottom of the first groove 13316 extends from the bottom of the first groove 13316 to the outside of the first groove 13316 through the gap between the coil 1332 and the first groove 13316.

In another embodiment, referring to fig. 7, the battery assembly 13 further includes a magnetic connector 131 disposed at an end of the battery holder near the atomizer 12. The magnetic connector 131 is used for magnetic attraction with the identifier 121 to physically connect the atomizer 12 with the battery assembly 13.

In the flavor recognition mode, the oscillation authentication circuit 13422 receives the oscillation signal generated by the LC oscillation circuit, compares the oscillation signal with a predetermined oscillation signal, and determines the flavor type of the nebulizer 12 when the oscillation signal is a predetermined oscillation signal.
