At least two atomizers of the plurality of atomizers can be independently operated to independently generate the aerosol.

Each atomizer may also have an atomizing core 24 therein, the air flow path between the atomizing core 24 and the fluid in the storage chamber 23 being in communication, the atomizing core 24 being configured to atomize the liquid formulation to produce an aerosol therefrom. The atomizing core 24 may include a wick element, which may be a porous body or a fiber, capable of absorbing the liquid formulation and directing the liquid formulation into an atomizing area of the heat generating element, and a heat generating element for atomizing at least a portion of the liquid formulation on the wick element to form an aerosol. The heating element may be bonded to the wicking element such that the heating element can be integral with the wicking element.

Each atomizer may further have an air duct 25 therein, the air duct 25 providing at least part of an air flow path between the atomizing core 24 and the fluid of the suction nozzle 4, and aerosol generated by the atomization of the atomizing core 24 may enter the suction nozzle 4 through the air duct 25, the storage chamber 23 may be disposed around the air duct 25, or the air duct 25 may be disposed at one side of the storage chamber 23.

Alternatively, in another example, referring to fig. 2, at least part of the atomizing core 24 may be disposed in the air duct 25, the air duct 25 may be provided with a liquid guiding hole, the atomizing core 24 may be in fluid communication with the storage chamber 23 through the liquid guiding hole, the liquid formulation in the storage chamber 23 may pass through the liquid guiding hole to be absorbed by the liquid absorbing element and atomized by the heating element, or part of the liquid absorbing element may pass through the liquid guiding hole to enter the storage chamber 23 to absorb and conduct the liquid formulation.

Referring to fig. 3, each atomizer may further comprise a first flexible member 26 having a first channel 261, the first flexible member 26 being disposed adjacent to the suction nozzle 4, the first channel 261 being in fluid communication with the air duct 25 in the atomizer, i.e. the first channel 261 providing a channel for communication between the air duct 25 and the suction nozzle 4, the first flexible member 26 sealing the upper end of the respective storage chamber 23 or providing a sealed connection between the air duct 25 and the suction nozzle 4.

In an embodiment, referring to fig. 2, the suction nozzle 4 has a plurality of tubular bodies 411, the plurality of tubular bodies 411 are correspondingly communicated with the air ducts 25 of the plurality of atomizers, and one end of the tubular body 211, which is opposite to the air ducts 25, is an air outlet for the smoke to enter the oral cavity of the user, so the suction nozzle 4 has a plurality of air outlets, and the plurality of air outlets can be arranged in a row.

Alternatively, in other embodiments, the nozzle 4 has an air outlet at its end, with which the air ducts 25 of a plurality of atomizers are in communication.

At least part of the airflow detecting assembly 3 is disposed in the housing 4, and includes a plurality of airflow detectors, for example, a first airflow detector 31 and a second airflow detector 32, where the number of airflow detectors is consistent with the number of atomizers, and the plurality of airflow detectors are electrically connected to the plurality of atomizers in one-to-one correspondence, that is, the first atomizer 21 is electrically connected to the first airflow detector 31, and the second atomizer 22 is electrically connected to the second airflow detector 32.

In one example, when the airflow path between one airflow detector and the electrically connected nebulizer is conductive, the airflow detector responds to the detected airflow change to control the power supply assembly 6 to supply power to the electrically connected nebulizer so as to enable the nebulizer to generate aerosol, and thus the airflow detector can form an actuating switch for actuating the electrically connected nebulizer to generate aerosol.

More specifically, referring to fig. 3, the power supply assembly 6 includes a power supply 61 and a circuit board 62, and the power supply 61 may include any suitable battery. The battery may be a rechargeable battery or the battery may be a disposable battery. In one embodiment, the battery is a lithium ion battery. Alternatively, the battery may 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 lithium polymer battery.

The circuit board 62 has a plurality of circuits, and the circuits are electrically connected with the power source 61 to form a plurality of power supply circuits, different atomizers can be located in different power supply circuits, and the power supply circuits can be shared by partial circuits or be shared by all wireless circuits.

In the example shown in fig. 3, the air flow detection assembly 3 is fixed on the circuit board 62, and the first air flow detector 31 and the second air flow detector 32 may be held close to each other on the circuit board 62. In an example, the circuit board 62 is connected to the bracket 5 through the airflow detecting assembly 3 so as to be held inside the housing 4, and there may be no direct contact between the circuit board 62 and the bracket 5. In one example, the circuit board 62 is coupled to the bracket 5and supported by the bracket 5, while the circuit board 62 is capable of supporting the airflow detection assembly 3.

The first airflow detector 31 may be disposed on or connected to a power supply circuit between the first atomizer 21 and the power source 61, the second airflow detector 32 may be disposed on or connected to a power supply circuit between the second atomizer 22 and the power source 61, the first airflow detector 31 and the second airflow detector 32 forming switch-like elements such that the first airflow detector 31 is capable of controlling the respective power supply circuit to be electrically conductive based on the detected airflow variation result thereof, such that the first airflow detector 31 is capable of controlling the power source 61 to supply the first atomizer 21 with power for atomizing the liquid formulation thereof, and the second airflow detector 32 is capable of controlling the respective power supply circuit to be electrically conductive based on the detected airflow variation result thereof, such that the second airflow detector 32 is capable of controlling the power source to supply the second atomizer 22 with power for atomizing the liquid formulation thereof.

Alternatively, when the airflow path between one airflow detector and the atomizer electrically connected thereto is on, the airflow detector counts the operating parameters of the atomizer electrically connected thereto, such as the accumulated number of suction openings or the remaining number of suction openings, the accumulated duration of operation, and/or the remaining duration of operation, according to the result of detecting the airflow change thereof, and may control the sensory cue to send a cue signal to the user when the operating parameters reach a preset value, such as the accumulated number of suction openings reaches a preset total number of suction openings or when the remaining number of suction openings is exhausted, or control the power supply assembly 6 to stop supplying power to the atomizer continuously.

In one example, the housing 4 is provided with a window corresponding to the storage chamber 23 of the nebulizer, and a user can observe the storage amount of the liquid preparation in the storage chamber 23 through the window.

Referring to fig. 1-10, the aerosol-generating device further comprises a switch 1. The switch 1 is movable relative to the housing 4 between at least a first position and a second position, and when the switch 1 is in the first position, the air flow path between the first air flow detector 31 and the first atomizer 21 is conductive, so that the first air flow detector 31 is capable of controlling the power supply 61 to supply power to the first atomizer 21 in response to an air flow change. When the switch 1 is in the second position, the airflow path between the second airflow detector 32 and the second atomizer 22 is conductive, so that the second airflow detector 32 can control the power supply 61 to supply power to the second atomizer 22 in response to the airflow variation. Thus, by moving the switch 1 to a position, a nebulizer in fluid communication with the airflow detector in the airflow detection assembly may be selected such that when the user sucks the suction nozzle 41, the selected nebulizer is able to generate aerosol or the operating parameters of the selected nebulizer may be counted, the operating parameters of the nebulizer including the accumulated number of suction openings or the remaining number of suction openings, the accumulated length of time of operation and/or the remaining length of time of operation, etc.

In an embodiment the switch 1 is further configured to block the air flow path between the second air flow detector 32 and said second atomizer 22 in the first position and to block the air flow path between the first air flow detector 31 and the first atomizer 21 in the second position. Thus, the switch 1 is in the first position and in the second position, the air flow path between the second air flow detector 32 and said second atomizer 22, and the air flow path between the first air flow detector 31 and the first atomizer 21, only one of which is on and the other of which is off.

In an embodiment, referring to fig. 3, a switch 1 is provided between the atomizing assembly 2 and the air flow detection assembly 3. Thus, the change-over switch 1 is moved between the atomizing assembly 2 and the air flow detection assembly 3, and by the movement, the air flow path between at least one atomizer and the air flow detector electrically connected thereto is made conductive, for example, the air flow path between the first atomizer 21 and the first air flow detector 31 or the air flow path between the second atomizer 22 and the second air flow detector 32 is made conductive.

In an embodiment, referring to fig. 3 to 6, the aerosol generating device further includes a support 5, the switch 1 can move between at least a first position and a second position relative to the support 5, and a plurality of connecting channels are formed on the support 5, and the connecting channels are located between the atomizing assembly 2 and the airflow detecting assembly 3, so that the atomizer in the atomizing assembly 2 and the corresponding airflow detector in the airflow detecting assembly 3 can be conducted when one or more connecting channels are in an open state.

More specifically, referring to fig. 4 to 6, a first air guide channel 511 and a second air guide channel 512 are formed on the bracket 5, and the position of the switch 1 can be changed by moving the position of the switch 1, and the positional relationship between the switch 1 and the first air guide channel 511 and the second air guide channel 512 can be changed.

Referring to fig. 5, when the switch 1 is in the first position, the first air guide channel 511 is opened, so that the air flow path between the first atomizer 21 and the first air flow detector 31 is turned on. Referring to fig. 6, when the switch 1 is in the second position, the second air guide channel 512 is opened, so that the air flow path between the second atomizer 22 and the second air flow detector 32 is turned on.

As an example, referring to fig. 5, when the switch 1 is in the first position, the switch 1 blocks the second air guide channel 512, and referring to fig. 6, when the switch 1 is in the second position, the switch 1 blocks the first air guide channel 511.

More specifically, referring to fig. 5, when the switch 1 is located at the first position, the switch 1 blocks the second air guide channel 512, so that only the first air guide channel 511 of the first air guide channel 511 and the second air guide channel 512 is opened, and further, the air flow paths between only the first atomizer 21 and the corresponding air flow detector of the first atomizer 21 and the second atomizer 31 are turned on, and the air flow paths between the second atomizer 22 and the corresponding air flow detector are turned off.

Referring to fig. 6, when the switch 1 is in the second position, the switch 1 blocks the first channel 511, so that only the second air guide channel 512 of the first air guide channel 511 and the second air guide channel 512 is opened, and further, the air flow paths between the first atomizer 21 and only the second atomizer 22 and the corresponding air flow detector of the second atomizer 22 are turned on, and the air flow paths between the first atomizer 21 and the corresponding air flow detector are turned off.

As one example, the airflow path between the atomizing assembly and the airflow detection assembly is located outside of the switch, which can block the airflow path and not provide the airflow path, such that the airflow between the atomizer and the airflow detector electrically connected thereto cannot pass through the switch, and the switch does not have an airflow path inside that can communicate the atomizer and the airflow detector electrically connected thereto. Based on this, the change-over switch may be of solid construction.

Alternatively, in an example, referring to fig. 4 to 6, a sensing passage 11 may be formed in the change-over switch 1, and an air flow path between the atomizer and the air flow detector electrically connected thereto includes the sensing passage 11, so that an air flow between the atomizer and the air flow detector electrically connected thereto needs to circulate through the sensing passage 11.

More specifically, referring to fig. 5, when the switch 1 is in the first position, the sensing channel 11 on the switch 1 is connected to the first air guiding channel 511, so that the first air guiding channel 511 is opened, and the air flow between the first atomizer 21 and the first air flow detector 31 can flow along the first air guiding channel 511 and the sensing channel 11, so that the air flow path between the first atomizer 21 and the first air flow detector 31 is connected. At this time, the second air guide passage 512 may be blocked by other portions of the switch 1 because the sensorless passage 11 is turned on, thereby being in a closed state such that an air flow path between the second atomizer 22 and the air flow detector corresponding thereto is opened.

Referring to fig. 6, when the switch 1 is in the second position, the sensing channel 11 on the switch 1 is connected to the second air guiding channel 512, so that the second air guiding channel 512 is opened, and the air flow between the second atomizer and the second air flow detector can flow along the second air guiding channel 512 and the sensing channel 11, so that the air flow path between the second atomizer 22 and the second air flow detector 32 is connected. At this time, the first air guide passage 512 may be blocked by other portions of the switch 1 because the sensorless passage 11 is turned on, thereby being in a closed state such that the air flow path between the first atomizer 21 and the air flow detector corresponding thereto is opened.

In an embodiment, referring to fig. 4 to 6, the bracket 5 includes a first support plate 51, the switch 1 and the air flow detection assembly 3 are disposed at opposite sides of the first support plate 51, the switch 1 and the air flow detection assembly 3 may be spaced apart by the first support plate 51, the first support plate 51 may support the switch 1, and the switch 1 may be slidably connected with the first support plate 1. The first air guide passage 511 is located between the first air flow detector 31 and the switch 1, and the second air guide passage 512 is located between the second air flow detector 32 and the switch 1, and more specifically, at least part of the first air guide passage 511 and at least part of the second air guide passage 512 may be formed on the first support plate 51.

Thus, referring to fig. 5, when the switch 1 is in the first position, the first air guide channel 511 is opened, and the first air guide channel 511 communicates with the sensing channel 11, so that the air flow path between the first air flow detector 31 and the switch 1 is turned on. Referring to fig. 6, when the switch 1 is in the second position, the second air guide channel 512 is opened, and the second air guide channel 512 is communicated with the sensing channel 11, so that the air flow path between the second air flow detector 32 and the switch 1 is conducted.

In an embodiment, referring to fig. 4 to 6, the stand 5 includes a second support plate 52, the switch 1 and the atomizing assembly 2 are disposed on opposite sides of the second support plate 52, the atomizer in the atomizing assembly 2 may be spaced apart from the switch 1 by the second support plate 52, the second support plate 52 may support the atomizing assembly 2, and the switch 1 may be slidably connected to the second support plate 52.

A third air guide passage 521 may be provided between the first atomizer 21 and the switch 1, a fourth air guide passage 522 may be provided between the second atomizer 22 and the switch 1, and at least part of the third air guide passage 521 and at least part of the fourth air guide passage 522 may be formed on the second support plate 52.
