Referring to fig. 8, the invention also discloses a control method of the automatic liquid injection electronic atomization system, which is applicable to the above embodiment, and comprises the following steps:

s1, a first control module 7 acquires a nursing start signal formed by sucking of a user;

when the user sucks the spray nozzle 1, the air flow sensor 87 is triggered, and the air flow sensor 87 detects the sucking action of the user and sends a nursing start signal to the first control module 7.

S2, a first control module 7 controls an oral information acquisition assembly 6 to acquire oral information of a user according to a nursing start signal and sends the oral information of the user to the liquid injection equipment 200;

after acquiring the care start signal, the first control module 7 controls the light source 61 in the oral information acquiring assembly 6 to be turned on and controls the image sensor 62 to acquire an oral image to acquire oral information of the user. The first control module 7 stores the collected oral cavity information of the user in the first control module 7 and sends the oral cavity information to the liquid injection device 200.

S3, a first control module 7 controls the first aerosol generating assembly or the second aerosol generating assembly to work according to the oral cavity information of the user;

the step S3 specifically includes the following steps:

s31, judging the health condition of the oral cavity of the user according to the oral cavity information of the user;

Defining the oral health of the user based on the whiteness level of the teeth, e.g., as a health state when the whiteness level of the teeth is greater than a first preset value; when the whiteness of the teeth is not greater than a first preset value, a sub-health state is defined. The first control module 7 compares the image transmitted from the image sensor 62 with a preset image, thereby acquiring the health condition of the user's mouth.

S32, when the health condition of the oral cavity of the user is in a sub-health state, controlling the first aerosol generating assembly 4 to atomize the first atomized liquid and count a nursing start signal, so that the first aerosol formed by atomizing the first atomized liquid is discharged from the first air outlet hole 11;

when a user with a sub-healthy oral cavity starts inhaling, the first control module 7 controls the first aerosol generating assembly 4 to atomize the first atomized liquid, and the oral cavity of the user is protected by the first aerosol. In the process, the first control module 7 counts the number of mouths sucked by the user.

In one embodiment of the present invention, the step S32 further includes:

when the first aerosol generating component 4 is controlled to atomize the first atomized liquid, the air wave generating component 81 is controlled to work so as to drive the first aerosol formed by the first aerosol generating component 4 atomizing the first atomized liquid to flow in a wave-shaped manner towards the first air outlet hole 11.

And S33, when the number of times of generating the nursing start signal is larger than a preset value, controlling the second aerosol generating assembly 5 to atomize the second atomized liquid, so that the second aerosol formed by atomizing the second atomized liquid is discharged from the second air outlet hole 12.

The preset value may be 8, 9, 10, or the like, which may be set as needed, and is not particularly limited herein. When the user inhales again after inhaling the first aerosol for the preset times, the first control module 7 controls the second aerosol generating assembly 5 to atomize the second atomized liquid, and places the aerosol generating device 100 in a room or a vehicle, so that the aerosol formed by atomizing the second atomized liquid can flow into the surrounding environment to adjust the surrounding air, and the user can inhale his favorite taste for a long time.

The second air outlet hole 12 is positioned at the center line of the spray nozzle 1, and the second air mist is discharged from the second air outlet hole 12, so that the smell can be prevented from being mixed, the taste is full, the flow to the more areas of teeth is reduced, and the teeth are well protected. For example, for a user who likes to smoke a cigarette, the cigarette contains nicotine, and since the first aerosol contains the tooth protecting substance, the tooth protecting substance is attached to the surface of teeth and the surface of other tissues of the oral cavity, the problem that cavitation is generated in the cell pulp when the nicotine acts on periodontal ligament cells can be avoided, and meanwhile, the influence on DNA synthesis and cell proliferation of periodontal ligament cells and the attachment of cells to the tooth root surface can be avoided.

It will be appreciated that the stop 823 is located on the left side of the outlet of the first reservoir 301 when the inhalation is started, and the stop 823 blocks the air passage between the second reservoir 302 and the second air outlet hole 12. After the user has sucked the aerosol for a preset number of times, the first control module 7 controls the motor 821 to drive the stop 823 to move rightward and cover the outlet of the first liquid storage cavity 301 and the first air outlet hole 11 to block the air passage between the first liquid storage cavity 301 and the first air outlet hole 11, and the air passage between the second liquid storage cavity 302 and the second air outlet hole 12 is communicated. When the user sucks again, the first control module 7 controls the second aerosol generating assembly 5 to work, and the second aerosol flows out from the second air outlet hole 12.

S4, the liquid injection device 200 selects target atomized liquid to be injected into the first liquid storage cavity 301 or the second liquid storage cavity 302 according to the oral cavity information of the user.

The second control module 94 controls the mechanical arm 97 to place the aerosol-generating device 100 to be filled with liquid in the elastic fixing sleeve 961, and then controls the recognition module 91 to recognize the aerosol-generating device 100 and controls the vibrator 965 to vibrate, so that the atomized liquid leaked in the aerosol-generating device 100 flows out from the air inlet hole 24 to the surface acoustic wave device 966. After the vibrator 965 vibrates for a preset time, the vibrator 965 is controlled to stop vibrating, and then the optical signal transmitter 963 and the optical signal receiver 964 are controlled to operate to detect the amount of atomized liquid leakage.

After the detection is finished, the second control module 94 calculates the atomized liquid residual quantity of the aerosol generating device 100, then controls the mechanical arm 97 to convey the aerosol generating device 100 onto the conveyor belt 953 of the conveying mechanism 95, when the aerosol generating device 100 moves below the first liquid injector 921, the first air cylinder 926 drives the first mounting plate 925 to move downwards, after the aerosol generating device moves downwards to a preset position, the first mounting plate 925 stops moving, and then the first electric cylinder 924 drives the first piston 923 to move downwards, so that the first atomized liquid is injected into the first liquid storage cavity 301 from the first one-way valve 252 of the aerosol generating device 100.

After the first atomized liquid is injected, the second control module 94 controls the first cylinder 926 to drive the first mounting plate 925 to move upwards for a preset distance, and then controls the conveyor belt 953 of the conveying mechanism 95 to drive the aerosol generating device 100 to move below the second liquid injector 931. Then, the second air cylinder 936 moves the second mounting plate 935, and after moving downward to the predetermined position, the second mounting plate 935 stops moving, and then the second electric cylinder 934 drives the second piston 933 downward, thereby driving the second atomized liquid to be injected into the second liquid storage chamber 302 from the second one-way valve 262 of the aerosol-generating device 100.

In one embodiment, the S4 specifically includes:
