[0002] An electronic atomizer is an electronic product that atomizes a liquid to generate aerosol for a user to inhale. The liquid can be water, flavoring, or medicine. The electronic atomizer can be used for smoking cessation or disease treatment, and has a wide range of applications. The existing electronic atomizer includes a shell, an atomization assembly, a battery, and an airflow sensor arranged in the shell. The electronic atomizer detects the user's inhalation action through the airflow sensor to control the power supply of the battery, so that the heating element in the atomization assembly generates heat, and the liquid in the atomization assembly is atomized to form aerosol.

[0003] However, the existing electronic atomizer is not reasonable in liquid supply. When the user starts to inhale, the aerosol discharge is relatively large due to the sufficient liquid. During the inhalation process, the aerosol discharge is large or small due to the poor liquid supply, which causes the user to cough when inhaling the aerosol.

[0014] Preferably, the capillary force of the third liquid suction pipe is greater than the capillary force of the first liquid suction pipe, and the third liquid suction pipe is coaxially arranged with the first liquid suction pipe.

[0015] The application further discloses a control method of an electronic atomizer, which is used for controlling the electronic atomizer and comprises the following steps:

[0034] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly understood, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

The terms "first", "second", etc. are only for the purpose of convenient description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "multiple" is two or more, unless otherwise specifically limited. The meaning of "several" is one or more, unless otherwise specifically limited.

[0036] Referring to Figures 1 to 6 The electronic atomizer comprises a shell 1, a first atomization assembly 2, a second atomization assembly 3, a first compression assembly 4, a second compression assembly 5, an airflow sensor 6 and a controller 7, and the shell 1 is provided with a first cavity 101. In the embodiment, the shell 1 comprises a first sleeve 11, a second sleeve 12 and a third sleeve 13, the second sleeve 12 is detachably arranged in the first sleeve 11, the first cavity 101 is formed in the second sleeve 12, and the second cavity 102 is formed between the first sleeve 11 and the second sleeve 12.

[0037] The first sleeve 11 is located in the third sleeve 13, and a tubular heat insulation gap is formed between the third sleeve 13 and the first sleeve 11, so that the third sleeve 13 is prevented from being overheated in use. One end of the third sleeve 13 is connected with a bottom cover 14, and the bottom cover 14 is provided with an air inlet hole 141 which is communicated with the second atomization assembly 3. One end of the shell 1 is connected with a suction nozzle 15, and the suction nozzle 15 is connected with the first sleeve 11, the second sleeve 12 and the third sleeve 13. The bottom cover 14 and the suction nozzle 15 are located at two opposite ends of the third sleeve 13. The suction nozzle 15 is provided with a mist outlet hole 151 which is communicated with the first atomization assembly 2 and the second atomization assembly 3.

[0038] The first cavity 101 is arranged with an isolation tube 80, a first liquid suction tube 81, a second liquid suction tube 82, a third liquid suction tube 83 and a fourth liquid suction tube 84. The isolation tube 80 comprises an upper receiving section and a lower receiving section, and the first liquid suction tube 81 is located in the upper receiving section and communicated with the mist outlet hole 151. The isolation tube 80 is used to prevent external force from being conducted to the first liquid suction tube 81, so as to prevent the first liquid suction tube 81 from being deformed due to the external force, thereby causing unstable liquid supply. In addition, if the external force is conducted to the first atomization assembly 2 through the first liquid suction tube 81, the first atomization assembly 2 may be deformed, thereby affecting the resistance value of the first atomization assembly 2 and the stability of the aerosol output.

[0039] The second liquid suction tube 82 is located in the first cavity 101 and sleeved on the outside of the upper receiving section, so as to supplement the atomization liquid to the first liquid suction tube 81 when the atomization liquid in the first liquid suction tube 81 is insufficient. The upper end of the upper receiving section is provided with a first liquid inlet hole 801. Preferably, in order to prevent the atomization liquid in the second liquid suction tube 82 from being sprayed into the first liquid suction tube 81 when the liquid is discharged, the cross-sectional area of the liquid inlet of the first liquid inlet hole 801 is smaller than the cross-sectional area of the liquid outlet of the first liquid inlet hole 801. More preferably, the angle formed by the center line of the first liquid inlet hole 801 and the cross section of the isolation tube 80 is greater than 45°. Thus, the impact force of the inflowing atomization liquid on the first liquid suction tube 81 when the liquid is discharged is greatly reduced.

[0040] It can be understood that the isolation tube 80 can be made of plastic tube or metal tube and the like. In the embodiment, the isolation tube 80 is a stainless steel tube, and the first to fourth liquid suction tubes 81-84 are all cotton tubes. It can be understood that in other embodiments, the first to fourth liquid suction tubes 81-84 can be made of other porous materials, which are not specifically limited herein.

[0041] The porosity of the upper end of the first liquid suction tube 81 is less than that of the lower end of the first liquid suction tube 81, and the capillary force of the upper end of the first liquid suction tube 81 is greater than that of the lower end of the first liquid suction tube 81. Therefore, when the atomized liquid in the first liquid suction tube 81 is less, the atomized liquid is uniformly or slightly different in the upper and lower parts as a whole, respectively, even under the influence of gravity, thereby stably supplying the liquid to the first atomization assembly 2 in the upper and lower parts, so as to realize the stable aerosol output and avoid the problem that the user easily coughs when smoking due to the unstable aerosol output. Preferably, the porosity of the first liquid suction tube 81 gradually increases from top to bottom, and the capillary force of the first liquid suction tube 81 gradually decreases from top to bottom.

[0042] In a preferred embodiment of the present application, the porosity of the first liquid suction tube 81 is less than that of the second liquid suction tube 82, and the capillary force of the first liquid suction tube 81 is greater than that of the second liquid suction tube 82. Therefore, not only can the liquid storage capacity of the second liquid suction tube 82 region be increased, but also the stability of the atomized liquid supply can be ensured. The third liquid suction tube 83 is located in the lower receiving section, and the first liquid suction tube 81 and the third liquid suction tube 83 are provided with a first liquid isolation ring 85. The first liquid isolation ring 85 is used to prevent the atomized liquid at the first liquid suction tube 81 from flowing towards the third liquid suction tube 83, so as to avoid the problem that the atomized liquid in the first liquid suction tube 81 flows into the third liquid suction tube 83 due to gravity, thereby causing insufficient supply of the atomized liquid in the first liquid suction tube 81. The first liquid isolation ring 85 is provided with a liquid discharge hole 851, and the liquid discharge hole 851 is connected with a switch 86. Preferably, the capillary force of the third liquid suction tube 83 is greater than that of the first liquid suction tube 81, and the third liquid suction tube 83 is coaxially arranged with the first liquid suction tube 81. Therefore, the atomized liquid can be well latched to avoid leakage of the atomized liquid.

[0043] The switch 86 includes a first motor 861 and a connecting rod 862. The first motor 861 is electrically connected with the controller 7. One end of the connecting rod 862 is movably inserted into the liquid discharge hole 851, and the other end of the connecting rod 862 is threadedly connected with the first motor 861. When the first motor 861 reverses, the connecting rod 862 moves downward, and when the first motor 861 rotates forward, the connecting rod 862 moves upward, thereby realizing the opening and closing of the liquid discharge hole 851. In the embodiment, the cross sections of the connecting rod 862 and the liquid discharge hole 851 are both square.

[0044] The first atomization assembly 2 is located inside the lower end of the first liquid suction pipe 81, and the height of the position where the first liquid inlet hole 801 is located is higher than the height of the position where the first atomization assembly 2 is located. Therefore, the atomized liquid transported from the upper end of the second liquid suction pipe 82 flows slowly to the direction where the first atomization assembly 2 is located under the action of gravity, and the first atomization assembly 2 can obtain stable atomized liquid from the first liquid suction pipe 81.

[0045] In the embodiment, the first atomization assembly 2 is located downstream of the second atomization assembly 3, which includes the first liquid suction cotton column 21 and the first heating element 22. The first liquid suction cotton column 21 is located in the first liquid suction pipe 81 and is in contact with the first liquid suction pipe 81. The first heating element 22 is located in the first liquid suction cotton column 21 and is in contact with the first liquid suction cotton column 21, and is used for atomizing the atomized liquid in the first liquid suction cotton column 21. The first heating element 22 can be a tubular heating wire or a tubular heating sheet, and the structure is not limited here. More specifically, in the embodiment, the first heating element 22 is a tubular heating wire, and the heating wire is coaxially arranged with the first liquid suction cotton column 21 and the first liquid suction pipe 81.

[0046] The second atomization assembly 3 is located in the third liquid suction pipe 83 and is in communication with the first atomization assembly 2. The second atomization assembly 3 includes the second liquid suction cotton column 31 and the second heating element 32. The second liquid suction cotton column 31 is located in the third liquid suction pipe 83 and is in contact with the third liquid suction pipe 83. The second heating element 32 is located in the second liquid suction cotton column 31 and is in contact with the second liquid suction cotton column 31, and is used for atomizing the atomized liquid in the second liquid suction cotton column 31. The second heating element 32 can be a tubular heating wire or a tubular heating sheet, and the structure is not limited here. More specifically, in the embodiment, the second heating element 32 is a tubular heating wire, and the heating wire is coaxially arranged with the second liquid suction cotton column 31 and the third liquid suction pipe 83. The fourth liquid suction pipe 84 is sleeved on the outer circumferential surface of the lower receiving section, and the upper end of the lower receiving section is provided with a second liquid inlet hole 802 for guiding the atomized liquid at the fourth liquid suction pipe 84 into the third liquid suction pipe 83.

[0047] The atomized liquid in the first liquid suction pipe 81 and the atomized liquid in the second liquid suction pipe 82 can be the same or different. In a preferred embodiment of the present application, the first liquid suction pipe 81 adsorbs the first atomized liquid, and the second liquid suction pipe 82 adsorbs the second atomized liquid. The first atomized liquid and the second atomized liquid both contain propylene glycol, glycerol and flavoring spices. The mass fraction of glycerol in the second atomized liquid is greater than that in the first atomized liquid, so as to better ensure the stability of the aerosol discharge amount. Preferably, the saturation degree of the first atomized liquid in the first liquid suction pipe 81 is less than that of the second atomized liquid in the second liquid suction pipe, so as to avoid over-saturation of the first liquid suction cotton column 21, so that the size of the aerosol particles is greatly different before and after, thereby causing the problem of user discomfort.

[0048] It can be understood that, as a solvent, propylene glycol is used for dissolving the flavoring agent to provide the user with the desired taste, and glycerol is used to generate the aerosol in the form of mist, and the proportion of which basically determines the size of the aerosol amount. Since part of the glycerol will be in contact with the high-temperature aerosol during the process of being transported from the upper end of the first liquid suction pipe 81 to the first atomization assembly 2 after being discharged from the first liquid inlet hole 801, and thus vaporized to form the aerosol, the lost glycerol can be supplemented through the above-mentioned arrangement, so as to better ensure that the aerosol discharge amount is relatively stable after being used for a period of time and when it is first used. Preferably, the third liquid suction pipe 83 also adsorbs the first atomized liquid, and the fourth liquid suction pipe 84 also adsorbs the second atomized liquid.

[0049] In a preferred embodiment of the present application, the electronic atomizer further comprises a second liquid separation ring 87 located between the second liquid suction pipe 82 and the fourth liquid suction pipe 84, for preventing the atomized liquid at the second liquid suction pipe 82 from flowing into the fourth liquid suction pipe 84. Preferably, the second liquid separation ring 87 is integrally formed with the liquid separation pipe.

[0050] The first compression assembly 4 comprises a first compression ring 41 located at the bottom of the second liquid suction pipe 82, and a first driver 42 connected to the first compression ring 41, for extruding the second liquid suction pipe 82 upward to make the atomized liquid in the second liquid suction pipe 82 flow into the first liquid suction pipe 81 from the first liquid inlet hole 801. The first driver 42 comprises a second motor 421 fixed at the second housing 1, and a first screw rod 422 having a first end connected to the second motor 421 and a second end threadedly connected to the first compression ring 41, and the first screw rod 422 is capable of driving the first compression ring 41 to move up and down when it rotates.

[0051] The second compression assembly 5 comprises a second compression ring 51 located at the bottom of the fourth liquid suction pipe 84, and a second driver 52 connected to the second compression ring 51, for extruding the fourth liquid suction pipe 84 upward to make the atomized liquid in the fourth liquid suction pipe 84 flow into the third liquid suction pipe 83 from the second liquid inlet hole 802. The second driver 52 comprises a third motor 521 fixed at the second housing 1, and a second screw rod 522 connected to the third motor 521 and threadedly connected to the second compression ring 51, and the second screw rod 522 is capable of driving the second compression ring 51 to move upward to extrude the atomized liquid at the fourth liquid suction pipe 84 and transport the atomized liquid from the second liquid inlet hole 802 to the third liquid suction pipe 83 when it rotates.

[0052] In an embodiment of the present application, the electronic atomizer further comprises a capacitor 91 electrically connected to the controller 7, the capacitor 91 is located in the first suction tube 81 and used to detect the remaining amount of the atomized liquid in the first suction tube 81. The capacitor 91 comprises a first electrode plate 911 and a second electrode plate 912, the first electrode plate 911 and the second electrode plate 912 are oppositely arranged and located in the first suction tube 81, and the first electrode plate 911 and the second electrode plate 912 are electrically connected to the controller 7, the controller 7 calculates the remaining amount of the atomized liquid in the first suction tube 81 according to the capacitance of the capacitor 91. Preferably, the capacitor 91 is located at a position higher than the position of the first atomization assembly 2, so as to avoid the interference of the first atomization assembly 2 and improve the accuracy of detection.

[0053] In an embodiment of the present application, the suction nozzle 15 is provided with a sealing top cover 92, and the sealing top cover 92 is sealingly connected to the shell 1. The sealing top cover 92 is provided with a mounting groove 921, an air outlet groove 922, a plug hole 923, a connecting groove 924 and a fixing groove 925, the mounting groove 921 is used to mount the airflow sensor 6 and is in communication with the air outlet groove 922. The air outlet groove 922 is used to communicate with the mist outlet hole 151. Specifically, the air outlet groove 922 extends along the transverse direction of the electronic atomizer. The plug hole 923 is in communication with the air outlet groove 922, and the plug hole 923 extends along the longitudinal direction of the electronic atomizer. The connecting groove 924 is located between the air outlet groove 922 and the fixing groove 925, a first end of the connecting groove 924 is in communication with the air outlet groove 922 and the plug hole 923, and a second end of the connecting groove 924 is in communication with the fixing groove 925. The air outlet groove 922 communicates with the mist outlet hole 151 through the connecting groove 924.

[0054] The airflow sensor 6 is mounted in the mounting groove 921 of the sealing top cover 92 and is in communication with the air outlet groove 922, so as to communicate with the mist outlet hole 151 through the air outlet groove 922. The height of the bottom wall of the air outlet groove 922 is higher than the height of the bottom wall of the connecting groove 924, so that the condensed liquid is not easy to flow into the air outlet groove 922 and then flow into the airflow sensor 6. The sealing top cover 92 is further provided with an air inlet groove 926 in communication with the airflow sensor 6, and the air inlet groove 926 is located below the airflow sensor 6.

[0055] In an embodiment of the present application, the electronic atomizer further comprises a third atomization assembly 93, an elastic reset member 94, an air path blocking assembly 95, and a mouthpiece cover 96. The third atomization assembly 93 is located at the sealing top cover 92 and abuts against the orifice of the mist outlet hole 151. The third atomization assembly 93 is used to atomize the condensate at the mist outlet hole 151. In this embodiment, the third atomization assembly 93 comprises a third liquid absorbing cotton column 931 and a third heating element 932. The third liquid absorbing cotton column 931 is in a cylindrical shape. The first end of the third liquid absorbing cotton column 931 is inserted into the fixing groove 925, and the second end of the third liquid absorbing cotton column 931 abuts against the orifice of the mist outlet hole 151. Thus, the third liquid absorbing cotton column 931 can well absorb the condensate flowing down from the mist outlet hole 151, avoiding the condensate from flowing around.

[0056] The elastic reset member 94 is located in the shell 1 and elastically abuts against the air path blocking assembly 95. The mouthpiece cover 96 is provided with a liquid pushing plug 961. The mouthpiece cover 96 is detachably connected with the mouthpiece 15. In the first state, the mouthpiece cover 96 is separated from the mouthpiece 15, and the air path blocking assembly 95 closes the air outlet groove 922. That is, when the present application is not used, the mouthpiece cover 96 is separated from the mouthpiece 15. Under the elastic force of the elastic reset member 94, the air path blocking assembly 95 automatically closes the air outlet groove 922, thereby hindering the condensate from flowing towards the airflow inductor 6.

[0057] In the second state, the mouthpiece cover 96 is arranged at the mouthpiece 15, and the liquid pushing plug 961 is inserted into the mist outlet hole 151 to push the condensate in the mist outlet hole 151 to flow towards the third atomization assembly 93. At the same time, the mouthpiece cover 96 drives the air path blocking assembly 95 to open the air outlet groove 922. Thus, the user can normally use the present application. Therefore, the problem that the user easily inhales the condensate when smoking this time because the aerosol left by the user when smoking last time condenses into condensate in the mist outlet hole 151 is well avoided. In order to avoid too much condensate remaining in the liquid pushing plug 961, the length of the liquid pushing plug 961 is less than one fourth of the length of the mist outlet hole 151. Specifically, the length of the liquid pushing plug 961 is preferably within 2.5 mm.

[0058] In a preferred embodiment of the present application, the air path blocking assembly 95 comprises a blocking piece 951 and a first magnetic piece 952 connected to the blocking piece 951, the blocking piece 951 is connected to the elastic reset piece 94 and movably connected to the sealing top cover 92, specifically, the blocking piece 951 penetrates the insertion hole 923 and extends into the connecting groove 924. The nozzle cover 96 comprises a cover body 962 and a second magnetic piece 963 connected to the cover body 962, the cover body 962 is provided with the liquid pushing plug 961, in the first state, the elastic reset piece 94 drives the blocking piece 951 to close the air outlet groove 922. In the second state, the second magnetic piece 963 repels the first magnetic piece 952, so that the air path blocking assembly 95 opens the air outlet groove 922, so that the air outlet groove 922 can communicate with the mist outlet hole 151 through the connecting groove 924. It can be understood that the elastic reset piece 94 can be a spring or a spring sheet, and its structure is not limited here. In this embodiment, the first magnetic piece 952 and the second magnetic piece 963 are both magnets.

[0059] In a preferred embodiment of the present application, the electronic atomizer further comprises a gas pushing plug 97 connected to the blocking piece 951; in the first state, the gas pushing plug 97 is at least partially inserted into the air inlet groove 926, and in the second state, the gas pushing plug 97 is spaced apart from the slot of the air inlet groove 926. That is, when the user finishes smoking and takes out the nozzle cover 96, the elastic reset piece 94 drives the blocking piece 951 to move towards the nozzle 15, and at the same time, the blocking piece 951 drives the gas pushing plug 97 to insert into the air inlet groove 926. Therefore, during the process of the user finishing smoking and then taking out the nozzle cover 96, the airflow in the air outlet groove 922 continues to flow towards the mist outlet hole 151 through the driving of the gas pushing plug 97, avoiding the residual aerosol in the nozzle 15 from flowing into the airflow inductor 6, improving the service life of the airflow inductor 6, in addition, when the blocking piece 951 moves to the preset position, it is separated from the airflow inductor 6 and the mist outlet hole 151. This structure is ingenious, low in cost, convenient to use, easy to implement and good in effect.

[0060] In a preferred embodiment of the present application, the electronic atomizer further comprises an elastic sealing sheet 98 located on the side of the sealing top cover 92 facing away from the second cavity 102 and covering the slot of the air outlet groove 922 to seal the slot on the side facing away from the second cavity 102. Therefore, when the user inhales, the airflow in the installation groove 921 area can quickly flow to the mist outlet hole 151, thereby quickly triggering the airflow sensor 6, so as to improve the sensitivity of the airflow sensor 6 and improve the user experience. In addition, this structure is convenient to manufacture, reduces the manufacturing process, and improves the production efficiency. It can be understood that in the first state, the air path blocking component 95 abuts against the elastic sealing sheet 98. It can be understood that in an embodiment, the elastic sealing sheet 98 can not be provided, and the slot of the air outlet groove 922 on the side facing away from the second cavity 102 elastically abuts against the suction nozzle 15. In the first state, the air path blocking component 95 abuts against the suction nozzle 15.

[0061] In a preferred embodiment of the present application, the electronic atomizer further comprises a third magnetic member 991, a Hall sensor 992, and a battery 993. The third magnetic member 991 is installed at the suction nozzle cover 96 and cooperates with the Hall sensor 992. The Hall sensor 992 is installed in the sealing top cover 92 and electrically connected to the controller 7, and is used to detect whether the suction nozzle cover 96 is covered on the suction nozzle 15. The battery 993 is used to provide electric energy to power the electric devices such as the first atomization component 2, the second atomization component 3, and the third atomization component 93.

[0062] The controller 7 is electrically connected to the airflow sensor 6 and the battery 993, and is used to control the first atomization component 2, the second atomization component 3, and the third atomization component 93 to work at different times, and when the remaining amount of the atomizing liquid in the first suction tube 81 is less than the first preset value, the first atomization component 2 is prohibited from working, and the switch 86 is opened. That is, the first atomization component 2 and the second atomization component 3 do not work at the same time, and when the remaining amount of the atomizing liquid in the first suction tube 81 is less than the first preset value, the first atomization component 2 is permanently closed and the switch 86 is opened, so that the remaining atomizing liquid in the first suction tube 81 flows into the third suction tube 83, thereby avoiding waste of the atomizing liquid and being able to timely supplement the atomizing liquid to the third suction tube 83.

[0063] Please refer to Figure 7 The present application also discloses a control method of an electronic atomizer, which is used to control the above-mentioned electronic atomizer and comprises the following steps:

[0064] S1, obtaining the inhaling start signal transmitted by the airflow sensor 6;

[0065] After the user covers the mouthpiece cover 96 at the mouthpiece 15, the user can start to smoke, and the airflow at the air outlet groove 922 flows to the air outlet hole 151, so as to form a negative pressure, and the airflow sensor 6 is triggered to send a smoking start signal to the controller 7. The smoking start signal can be a high-level signal.

[0066] S2, according to the smoking start signal, determining whether the number of puffs of the user is odd or even and whether the remaining amount of the atomized liquid in the first liquid suction pipe 81 is greater than a first preset value;

[0067] Under normal circumstances, when the remaining amount of the atomized liquid in the first liquid suction pipe 81 is sufficient, the first atomization assembly 2 and the second atomization assembly 3 work alternately, so as to reduce the problem that the aerosol is unstable when the atomized liquid is insufficient.

[0068] S3, when the remaining amount of the atomized liquid in the first liquid suction pipe 81 is greater than the first preset value, and the number of puffs of the user is even, the first atomization assembly 2 is controlled to atomize the atomized liquid at a first atomization power, otherwise the second atomization assembly 3 is controlled to atomize the atomized liquid at a second atomization power, and the second atomization power is greater than the first atomization power.

[0069] Under normal circumstances, when the remaining amount of the atomized liquid in the first liquid suction pipe 81 is sufficient, the second atomization assembly 3 works first and the first atomization assembly 2 works later each time the user smokes, and the two work alternately for odd and even puffs each time the user smokes. Since the first atomization assembly 2 is located downstream of the airflow flowing direction of the second atomization assembly 3, the aerosol formed by the second atomization assembly 3 can absorb heat when passing through the first atomization assembly 2, therefore, by setting the second atomization power greater than the first atomization power, the amount of aerosol inhaled by the user each time can be stabilized, so that the user does not cough easily when smoking. For example, when the first atomization power is 9 watts, the second atomization power can be 9.5 watts. It can be understood that when the user finishes smoking, the controller 7 controls the third atomization assembly 93 to work to atomize the condensed liquid.

[0070] In a preferred embodiment of the present application, in S3, when the remaining amount of the atomized liquid in the first liquid suction pipe 81 is greater than the first preset value and less than a second preset value, the first driver 42 is controlled to drive the first pressing ring 41 to move upward to press the second liquid suction pipe 82.

[0071] When the remaining amount of the atomized liquid is greater than the first preset value and less than the second preset value, it indicates that the remaining amount is not too much and the long-term liquid supply cannot be performed, and the atomized liquid needs to be supplemented in time. At this time, the controller 7 controls the first driver 42 to drive the first pressing ring 41 to move upward by a preset distance, so as to press the second liquid suction pipe 82, so that the atomized liquid in the second liquid suction pipe 82 flows into the first liquid suction pipe 81. It can be understood that the first preset value and the second preset value can be set according to the type of the atomized liquid, which is not limited here.

[0072] In a preferred embodiment of the present application, in S3, when the remaining amount of the atomized liquid in the first liquid suction pipe 81 is not greater than the first preset value, the first atomization assembly 2 is prohibited from working, and the switch 86 is controlled to vibrate for a preset time after the second atomization assembly 3 stops working.

[0073] When the remaining amount of the atomized liquid in the first liquid suction pipe 81 is not enough, the first atomization assembly 2 is prohibited from working, and the second atomization assembly 3 atomizes the atomized liquid thereafter. The switch 86 is controlled to vibrate for a preset time after the second atomization assembly 3 stops working, so that the remaining atomized liquid in the first liquid suction pipe 81 flows into the third liquid suction pipe 83, realizing full use of the atomized liquid and avoiding waste. It can be understood that the purpose of vibration can be achieved by driving the connecting rod 862 to move up and down at high speed through the first motor 861.

[0074] In a preferred embodiment of the present application, the control method further comprises the following steps:

[0075] The number of puffs of the user is counted, and when the number of puffs is greater than a preset number and the cumulative amount of the condensed liquid at the third atomization assembly 93 is less than a third preset value, a condensed liquid leakage alarm signal is sent.

[0076] Due to the puffs, there must be condensation, and with the increase of the number of puffs, the condensed liquid must increase. Assuming that the preset number of puffs is n, if the cumulative amount of the condensed liquid is still less than the third preset value after n puffs, it indicates that the second atomization assembly 3 is not assembled in place, and the condensed liquid in the atomization hole 151 has leaked to other areas. Therefore, the controller 7 sends a condensed liquid leakage alarm signal, thereby protecting the health of the user.

[0077] In a preferred embodiment of the present application, the control method further comprises:

[0078] According to the start signal of the puffs, it is detected whether the suction nozzle cover 96 is covered on the suction nozzle 15, and when it is detected that the suction nozzle cover 96 is not covered on the suction nozzle 15, the first atomization assembly 2 and the second atomization assembly 3 are prohibited from heating and a sealing failure signal is sent.

[0079] When the controller 7 acquires the smoking start signal transmitted by the airflow sensor 6, it detects whether the mouthpiece cover 96 is covered on the mouthpiece 15 through the Hall sensor 992. When it is detected that the mouthpiece cover 96 is not covered on the mouthpiece 15, it indicates that the air path blocking assembly 95 has failed, and the controller 7 sends a sealing failure signal. This method not only can simply and efficiently detect the sealing property of the air path blocking assembly 95, but also protects the airflow sensor 6 well. It can be understood that the controller 7 can include a single-chip microcomputer, a loudspeaker and a light-emitting alarm electrically connected to the single-chip microcomputer. The loudspeaker is used to send a condensed liquid leakage alarm signal, and the light-emitting alarm is used to send a sealing failure signal.

[0080] In summary, first, since the capillary force at the upper end of the first liquid suction pipe 81 is greater than the capillary force at the lower end of the first liquid suction pipe 81, and the first atomization assembly 2 is located inside the lower end of the first liquid suction pipe 81, the atomized liquid in the first liquid suction pipe 81 is uniformly or not greatly different in the upper and lower parts when the amount of atomized liquid is small, even under the influence of gravity, thereby stably supplying the first atomization assembly 2 with atomized liquid from the upper and lower parts, and thereby realizing stable aerosol output and avoiding unstable aerosol output, which can easily cause the user to cough when smoking.

[0081] It will be obvious to a person skilled in the art that, without departing from the spirit or essential characteristics of the application, the present application can be implemented in other specific forms. The present examples are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the description given above, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
