Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and more specifically, to a leak-proof electronic atomizer and its control method. Background Technology

[0002] Electronic atomizing devices are electronic products that atomize a liquid to produce an aerosol for users to inhale. The liquid can be water, flavorings, or medicinal liquids. They have a wide range of applications, including addiction treatment and disease therapy. Existing electronic atomizing devices typically include a housing, an atomizing component, a controller, and a battery. The housing contains a liquid storage chamber and an air delivery chamber, with an outlet between the two. The atomizing component is located within the air delivery chamber, and its side wall has an inlet hole opposite the outlet hole to draw in the liquid. During operation, the controller controls the battery to power the atomizing component, enabling it to atomize the liquid delivered from the outlet hole.

[0003] Since the atomizing liquid is a fluid, it is liquid at room temperature, meaning it flows at room temperature. During the transportation of electronic atomizing devices, changes in external air pressure or temperature can cause the pressure in the liquid storage chamber to be greater than the pressure in the air delivery chamber. Due to this pressure difference, the atomizing liquid will leak from the liquid delivery hole. To solve this technical problem, the existing solution is to rotate the atomizing component before transportation to misalign the liquid inlet of the atomizing component with the liquid outlet of the liquid storage chamber. During transportation, even if the pressure in the liquid storage chamber is greater than the pressure in the air delivery chamber, there will be no leakage of atomizing liquid. However, this often leads to users forgetting to rotate the atomizing component to align the liquid outlet with the liquid inlet when using it for the first time, resulting in the atomizing component running dry due to lack of atomizing liquid, which is inconvenient for users. Summary of the Invention

[0004] The purpose of this invention is to provide a leak-proof electronic atomizer and its control method that are easy for users to use.

[0005] In a first aspect, the solution of the present invention to solve the above problems is to construct a leak-proof electronic atomizer, which includes a body, a first sealing element, a second sealing element, and an air supply element. The body includes a shell, an air guide tube, an atomizing component, a temperature regulating component, and a controller. The shell is provided with a liquid storage chamber, an air inlet, and a mist outlet. The liquid storage chamber is used to store atomizing liquid. The air guide tube is located inside the liquid storage chamber and an air guide cavity is formed inside the air guide tube. The first end of the air guide cavity is connected to the air inlet, and the second end of the air guide cavity is connected to the mist outlet. A liquid guide hole communicating with the liquid storage chamber is provided on the cavity wall of the air guide cavity.

[0006] The atomizing component is located within the air-guiding chamber and covers the liquid-guiding hole, and is used to atomize the atomized liquid; the temperature regulating component is used to heat the air in the air-guiding chamber and cool the atomized liquid in the liquid-reservoir chamber during transportation, and to heat the atomized liquid during use; the first seal is used to seal the air inlet during transportation; the second seal is detachably inserted into the mist outlet and is used to trigger the controller during transportation, so that the controller controls the temperature regulating component to operate according to the trigger signal generated by the second seal; the air supply component is used to supply air to the air-guiding tube before the first seal seals the air inlet; the controller is used to control the operation of the first seal, the air supply component, the atomizing component, and the temperature regulating component.

[0007] Preferably, the temperature regulating component includes a first semiconductor refrigeration element and a second semiconductor refrigeration element. The first semiconductor refrigeration element includes a first heating part and a first cooling part. The first heating part is at least partially located within the mist outlet and is used to heat the air in the air guide cavity during transport. The first cooling part extends into the liquid storage cavity and is used to cool the atomized liquid in the liquid storage cavity during transport. The second semiconductor refrigeration element is used to heat the atomized liquid during use.

[0008] Preferably, the leak-proof electronic atomizer further includes a heat-conducting tube, which is sleeved on the outer peripheral surface of the air-conducting tube and abuts against the first cooling unit.

[0009] Preferably, the second semiconductor cooling device includes a second heating section and a second cooling section. The second heating section is located in the liquid storage chamber and is used to heat the atomized liquid when in use. The second cooling section is located in the air guiding chamber and is used to cool the aerosol flowing through the air guiding chamber when in use.

[0010] Preferably, the leak-proof electronic atomizer further includes a heat-conducting ring, which is sleeved on the outer circumferential surface of the air guide tube and abuts against the second heating part. The heat-conducting ring is provided with a plurality of liquid passage holes, and the height of the liquid passage holes is higher than the height of the liquid guide holes.

[0011] Preferably, the second seal includes a plug body and a first magnet located inside the plug body, wherein the plug body is inserted into the mist outlet in the transport state; the body also includes a Hall sensor located inside the housing, which is used to respond to the coupling signal of the first magnet and trigger the controller according to the coupling signal.

[0012] Preferably, the air supply component includes a fan located inside the housing, which drives the gas at the air inlet into the air guide pipe.

[0013] Preferably, the leak-proof electronic atomizer further includes a pressure sensor, which is used to detect the pressure in the air duct and send the pressure signal in the air duct to the controller; the controller is also used to control the temperature regulation component to work according to the pressure signal.

[0014] In a second aspect, the present invention also discloses a control method for a leak-proof electronic atomizer as described in any of the first aspects above, comprising the following steps:

[0015] Step S1: Obtain the sealing signal of the second sealing element sealing the body;

[0016] Step S2: Based on the sealing signal, control the air supply component to supply air to the air guide cavity;

[0017] Step S3: When the air supply component has been working for a preset time, control the first sealing component to seal the air inlet.

[0018] Step S4: Obtain the air pressure in the air guiding chamber;

[0019] Step S5: If the air pressure in the air guide cavity is less than a preset value and the device is in transport mode, then control the temperature regulation component to heat the air in the air guide cavity and cool the atomized liquid in the liquid storage cavity.

[0020] Preferably, the following steps are included after step S5:

[0021] Step S6: Obtain a separation signal indicating that the second seal is disconnected from the body;

[0022] Step S7: Based on the separation signal, detect whether a smoking start signal generated when the user smokes is received;

[0023] Step S8: When the inhalation start signal is detected, the atomizing component is controlled to work, and the temperature regulating component is controlled to cool the aerosol in the air delivery chamber and heat the atomized liquid in the storage chamber.

[0024] The beneficial effects of this invention are as follows: Before transportation, the manufacturer seals the mist outlet of the main body with a second seal. The controller automatically controls the air supply component to supply air to the air guide chamber based on the sealing signal, ensuring that the air pressure in the air guide chamber is not less than the air pressure in the liquid storage chamber. When the air pressure in the air guide chamber is less than a preset value, the controller controls the temperature regulation component to heat the air in the air guide chamber and cool the atomized liquid in the liquid storage chamber. Therefore, it effectively ensures that there is no leakage during transportation. When the user needs to inhale, they only need to remove the second seal from the mist outlet to inhale normally, without the problem of dry burning due to lack of atomized liquid at the beginning of inhalation. Therefore, this invention has the advantages of preventing leakage during transportation, good sealing performance, compact structure, small size, easy transportation, and easy user use.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figures 1 to 5This invention discloses a leak-proof electronic atomizer, comprising a body 1, a first sealing element 2, a second sealing element 3, an air supply element 4, an air pressure sensor 5, and a piezoelectric sensor 6. The body 1 includes a housing 11, an air guide tube 12, an atomizing assembly 13, a temperature regulating assembly 14, a compression assembly 15, a controller 16, and a battery 17. The housing 11 is provided with a liquid storage chamber 101, an air inlet 102, and a mist outlet 103. The liquid storage chamber 101 is used to store the atomizing liquid. It is understood that as long as atomization is possible, the composition of the atomizing liquid is not specifically limited.

[0034] In this embodiment, the housing 11 includes a first sleeve 111, a second sleeve 112, a third sleeve 113, a nozzle 114, and a bottom cover 115. The second sleeve 112 is located inside the first sleeve 111, and a liquid storage chamber 101 is formed inside the second sleeve 112. A battery chamber 104 is formed between the first sleeve 111 and the second sleeve 112, and the battery chamber 104 is used to house the controller 16 and the battery 17. The first sleeve 111 is located inside the third sleeve 113. One end of the third sleeve 113 is connected to the nozzle 114, and the other end of the third sleeve 113 is connected to the bottom cover 115. The nozzle 114 is provided with a mist outlet 103, and the bottom cover 115 is provided with an air inlet 102. The air inlet 102 is connected to the mist outlet 103 through the atomizing component 13.

[0035] The liquid storage chamber 101 houses an isolation tube 116, a first suction tube 117, and a second suction tube 118, with the first suction tube 117 located within the isolation tube 116. The isolation tube 116 serves to prevent external forces from being transmitted to the first suction tube 117, thus avoiding deformation of the first suction tube 117 and resulting in unstable liquid supply. Furthermore, if external forces are transmitted to the atomizing component 13 through the first suction tube 117, it may cause deformation of the atomizing component 13, affecting its resistance and consequently the stability of the aerosol output. In other words, the isolation tube 116 protects the atomizing component 13 from external forces, ensuring stable resistance and thus stable aerosol output.

[0036] The second suction tube 118 is sleeved outside the isolation tube 116 to replenish the atomized liquid in the first suction tube 117 when the atomized liquid in the first suction tube 117 is insufficient. The first suction tube 117 and the second suction tube 118 are used to adsorb the atomized liquid. An inlet hole 1161 is provided at the upper end of the isolation tube 116. Preferably, to prevent the atomized liquid in the second suction tube 118 from spraying into the first suction tube 117 during dispensing, the cross-sectional area of ​​the inlet of the inlet hole 1161 is smaller than the cross-sectional area of ​​the outlet of the inlet hole 1161. More preferably, the angle formed between the centerline of the inlet hole 1161 and the cross-section of the isolation tube 116 is greater than 60°. This effectively reduces the impact force of the flowing atomized liquid on the first suction tube 117 during dispensing.

[0037] It is understood that the isolation tube 116 can be made of materials such as plastic or metal. In this embodiment, the isolation tube 116 is a stainless steel tube, and both the first suction tube 117 and the second suction tube 118 are cotton tubes. It is understood that in other embodiments, the first suction tube 117 and the second suction tube 118 can be made of other porous materials, and the materials are not specifically limited here.

[0038] The porosity of the upper end of the first suction tube 117 is less than that of the lower end, and the capillary force at the upper end of the first suction tube 117 is greater than that at the lower end. Therefore, when the amount of atomizing liquid in the first suction tube 117 is small, even under the influence of gravity, the atomizing liquid is uniform or has little difference between the upper and lower ends, thus ensuring a uniform and stable liquid supply to the atomizing component 13. This achieves a stable aerosol output and avoids the problem of unstable aerosol output, which can easily cause coughing when the user inhales. Preferably, the porosity of the first suction tube 117 gradually increases from top to bottom, and the capillary force of the first suction tube 117 gradually decreases from top to bottom.

[0039] In one embodiment of the present invention, the porosity of the first suction tube 117 is less than that of the second suction tube 118, and the capillary force of the first suction tube 117 is greater than that of the second suction tube 118. Therefore, not only can the liquid storage capacity in the region of the second suction tube 118 be increased, but the stability of the atomizing liquid supply is also ensured. The thickness of the first suction tube 117 is less than that of the second suction tube 118, thus better preventing leakage of atomizing liquid from the atomizing assembly 13 due to thermal expansion of the first suction tube 117.

[0040] In a preferred embodiment of the present invention, the atomizing liquid includes a first atomizing liquid and a second atomizing liquid. The first atomizing liquid is adsorbed in the first suction tube 117, and the second atomizing liquid is adsorbed in the second suction tube 118. Both the first and second atomizing liquids contain propylene glycol, glycerol, and flavorings. The mass fraction of glycerol in the second atomizing liquid is greater than that in the first atomizing liquid, thus better ensuring the stability of the aerosol output and effectively preventing coughing during inhalation. Preferably, the saturation of the first atomizing liquid in the first suction tube 117 is less than the saturation of the second atomizing liquid in the second suction tube 118, thereby preventing oversaturation of the absorbent cotton column 131, which could lead to significant differences in aerosol particle size and cause user discomfort.

[0041] It is understandable that propylene glycol, as a solvent, is used to solvent flavorings and fragrances to provide users with the desired taste, while glycerol is used to generate atomized aerosols, and its proportion basically determines the amount of aerosol. Since some glycerol comes into contact with the high-temperature aerosol during the process of being transported from the upper end of the first suction pipe 117 to the first atomizing component 13 after the atomizing liquid is discharged from the first inlet 1161, it vaporizes to form aerosol. Therefore, through the above-mentioned arrangement, the lost glycerol can be replenished, thereby better ensuring that the aerosol discharge volume is relatively stable after a period of use compared to the initial use.

[0042] The air guide tube 12 is located inside the liquid storage chamber 101, and the first liquid suction tube 117 is sleeved on the outside of the air guide tube 12. An air guide cavity 121 is formed inside the air guide tube 12. The first end of the air guide cavity 121 is connected to the air inlet 102, and the second end of the air guide cavity 121 is connected to the mist outlet 103. A liquid guide hole 1211 communicating with the liquid storage chamber 101 is provided on the cavity wall of the air guide cavity 121.

[0043] The atomizing component 13 is located within the air guiding chamber 121 and covers the liquid guiding hole 1211. It is used to atomize the atomized liquid and includes an absorbent cotton column 131 and a heating element 132. The absorbent cotton column 131 is located within the air guiding chamber 121 and contacts the first liquid suction tube 117 through the liquid guiding hole 1211. The heating element 132 is located within and in contact with the absorbent cotton column 131, and is used to atomize the atomized liquid within the absorbent cotton column 131. The heating element 132 can be a heating wire wound into a tubular shape or a tubular heating plate, etc., and its structure is not specifically limited here. More specifically, in this embodiment, the heating element 132 is a heating wire wound into a tubular shape, and the heating wire is coaxially arranged with the absorbent cotton column 131 and the first liquid suction tube 117.

[0044] The temperature regulating component 14 is used to heat the air in the air guide cavity 121 and cool the atomized liquid in the liquid storage cavity 101 during transport, and to heat the atomized liquid during use. In this embodiment, the temperature regulating component 14 includes a first semiconductor cooling element 141 and a second semiconductor cooling element 142. The first semiconductor cooling element 141 includes a first heating part 1411 and a first cooling part 1412. The first heating part 1411 is located inside the mist outlet 103 and is used to heat the air in the air guide cavity 121 during transport. The first cooling part 1412 extends into the liquid storage cavity 101 and is used to cool the atomized liquid in the liquid storage cavity 101 during transport. Therefore, the air pressure in the air guide cavity 121 is greater than the pressure in the liquid storage cavity 101, so that the atomized liquid in the liquid storage cavity 101 will not be excessively discharged from the liquid guide hole during transport, thus preventing leakage.

[0045] The second semiconductor cooling element 142 is used to heat the atomizing liquid during use, thus effectively preventing the atomizing liquid in the storage chamber 101 from being too cold, which could lead to excessive temperature difference when delivered to the atomizing assembly 13 and cause oil splattering. This also prevents the user from inhaling large particles of atomizing liquid. In this embodiment, the second semiconductor cooling element 142 includes a second heating part 1421 and a second cooling part 1422. The second heating part 1421 is located in the storage chamber 101 and is used to heat the atomizing liquid during use. The second cooling part 1422 is located in the air guide chamber 121 and is used to cool the aerosol flowing through the air guide chamber 121 during use. This ensures that the temperature difference between the aerosol and the nozzle 114 is small when the aerosol flows to the nozzle, thus greatly reducing the condensation of the aerosol in the mist outlet 103 and reducing the probability of the user inhaling condensate.

[0046] In a preferred embodiment of the present invention, the leak-proof electronic atomizer further includes a heat-conducting pipe 7 and a heat-conducting ring 8. The heat-conducting pipe 7 is sleeved on the outer peripheral surface of the air-conducting pipe 12 and abuts against the first cooling section 1412. Therefore, it can not only reduce the production process, but also effectively cool the depth of the liquid storage chamber 101, resulting in good cooling effect. It is understood that the air-conducting pipe 12 is made of a material with poor thermal conductivity, and its thermal conductivity is lower than that of the heat-conducting pipe 7. The heat-conducting ring 8 is sleeved on the outer peripheral surface of the air-conducting pipe 12 and abuts against the second heating section 1421. The heat-conducting ring 8 is provided with a plurality of liquid passage holes 81, and the height of the liquid passage holes 81 is higher than the height of the liquid-conducting holes. Therefore, the atomized liquid flowing out from the liquid passage holes 81 is heated, thereby better avoiding the problem of oil splattering during atomization due to excessively low atomized liquid temperature.

[0047] The compression assembly 15 includes a pressure ring 151 and a driver 152 connected to the pressure ring 151. The pressure ring 151 is located at the bottom of the second suction tube 118 and is used to squeeze the second suction tube 118 upward so that the atomized liquid in the second suction tube 118 flows into the first suction tube 117 from the liquid inlet 1161, thereby replenishing the atomized liquid in the first suction tube 117 in a timely manner and ensuring a stable aerosol discharge volume. The driver 152 includes a first motor 153 and a screw 154. The first motor 153 is fixed at the bottom cover 115. The first end of the screw 154 is connected to the first motor 153, and the second end of the screw 154 is threadedly connected to the pressure ring 151. When the screw 154 rotates, it can drive the pressure ring 151 to move up and down.

[0048] The height of the liquid inlet 1161 is higher than the height of the atomizing component 13. Because the height of the liquid inlet 1161 is higher than the height of the atomizing component 13, when the supply of atomizing liquid in the first suction tube 117 is insufficient, the atomizing liquid in the second suction tube 118 is drawn from the liquid inlet 1161 into the upper end of the first suction tube 117 by the compression component 15. Therefore, not only can the liquid be supplied in a timely manner, but the atomizing liquid transported from the upper end of the second suction tube 118 also flows slowly towards the atomizing component 13 under the action of gravity, which well ensures that the amount of atomizing liquid at the upper and lower ends of the first suction tube 117 is uniform or has little difference.

[0049] In one embodiment of the present invention, the body 1 further includes a sealing top cover 181, a first sealing sheet 182, an airflow sensor 183, an elastic reset member 184, an air path blocking assembly 185, and a Hall sensor 186. The sealing top cover 181 is located inside the housing 11 and is sealed to the housing 11. The sealing top cover 181 is provided with a mounting groove 1811, an air outlet groove 1812, an insertion hole 1813, and a connecting groove 1814. The mounting groove 1811 is used to install the airflow sensor 183 and communicates with the air outlet groove 1812. The air outlet groove 1812 is used to communicate with the mist outlet 103. Specifically, the air outlet groove 1812 extends along the transverse direction of the body 1. The insertion hole 1813 communicates with the air outlet groove 1812 and extends along the longitudinal direction of the body 1. A connecting groove 1814 is located between the air outlet groove 1812 and the mist outlet 103. The first end of the connecting groove 1814 communicates with the air outlet groove 1812 and the insertion hole 1813, and the second end of the connecting groove 1814 communicates with the mist outlet 103. The air outlet groove 1812 is connected to the mist outlet 103 through the connecting groove 1814. A first sealing plate 182 is placed on the upper surface of the sealing top cover 181 to seal the opening of the air outlet groove 1812.

[0050] The airflow sensor 183 is installed in the mounting groove 1811 at the sealed top cover 181 and communicates with the air outlet groove 1812 to connect to the mist outlet 103. The bottom wall of the air outlet groove 1812 is higher than the bottom wall of the connecting groove 1814, so condensate is less likely to flow into the air outlet groove 1812 and thus into the airflow sensor 183.

[0051] The elastic reset member 184 is located inside the housing 11 and elastically abuts against the air passage blocking assembly 185. In the transport state, the second seal 3 is inserted into the mist outlet 103 of the suction nozzle 114, connecting the second seal 3 to the body 1. The second seal 3 drives the air passage blocking assembly 185, which closes the air outlet groove 1812. That is, when the invention is not in use, the air outlet groove 1812 is automatically closed by the air passage blocking assembly 185, thereby preventing condensate from flowing towards the airflow sensor 183. It is understood that the elastic reset member 184 can be a spring or a sheet, etc., and its structure is not specifically limited here.

[0052] The second seal 3 is detachably inserted into the mist outlet 103 and is used to trigger the controller 16 during transport, so that the controller 16 controls the temperature regulating component 14 to operate according to the trigger signal generated by the second seal 3. In the use state, the second seal 3 is separated from the body 1, that is, the second seal 3 is separated from the nozzle 114. Under the restoring force of the elastic reset component 184, the air passage blocking component 185 moves downward to open the air outlet groove 1812, so that the airflow sensor 183 is connected to the mist outlet 103, and thus the user can use the invention normally.

[0053] In a preferred embodiment of the present invention, the airflow blocking assembly 185 includes a blocking member 1851 and an iron sheet 1852 connected to the blocking member 1851. The blocking member 1851 is connected to an elastic reset member 184 and is movably connected to a sealing top cover 181. Specifically, the first end of the blocking member 1851 passes through the insertion hole 1813 and extends into the connecting groove 1814, and the second end of the blocking member 1851 extends below the airflow sensor 183. The Hall sensor 186 is located inside the housing 11 and is mounted on the sealing top cover 181.

[0054] The first sealing element 2 is used to seal the air inlet 102 during transport. It includes a second motor 21 and a second elastic sealing sheet 22. The second motor 21 is mounted on the bottom cover 115, and the second elastic sealing sheet 22 is connected to the second motor 21. The second motor 21 drives the second elastic sealing sheet 22 to rotate, thereby causing the second elastic sealing sheet 22 to cover the air outlet of the air inlet 102 or move away from the air outlet of the air inlet 102. In this embodiment, the second elastic sealing sheet 22 is rectangular and expands when heated to seal the air inlet 102 more tightly. It can be made of a rigid sheet covered with a silicone layer. It is understood that its shape and material are not specifically limited here. In one embodiment, the silicone layer is doped with heat-expanding particles.

[0055] The second sealing element 3 includes a plug body 31 and a first magnet 32 ​​and a second magnet 33 located within the plug body 31. The plug body 31 is made of a material such as silicone to expand when heated. Preferably, the silicone contains particles that expand when heated. In the transport state, the plug body 31 is inserted into the mist outlet 103. The Hall sensor 186 is used to respond to the coupling signal of the first magnet 32 ​​and to generate a sealing signal based on the coupling signal to trigger the controller 16. In the transport state, the second magnet 33 is magnetically attracted to the iron sheet 1852 of the air passage barrier assembly 185, causing the barrier 1851 to isolate the air outlet groove 1812 from the mist outlet 103, thus effectively preventing the condensate in the mist outlet 103 from flowing towards the airflow sensor 183, effectively protecting the airflow sensor 183 from failure due to the influence of condensate. Since the second seal 3 is not directly or through a connector to the gas path barrier assembly 185, it effectively avoids the condensate at the gas path barrier assembly 185 from being introduced into the suction nozzle 114, greatly reducing the probability of ingesting the condensate at the gas path barrier assembly 185.

[0056] The air supply component 4 supplies air to the air guide tube 12 before the first seal 2 seals the air inlet 102. The air supply component 4 includes a fan located inside the housing 11, which drives the gas at the air inlet 102 into the air guide tube 12. When the second seal 3 is inserted into the mist outlet 103, the controller 16 controls the fan to operate, causing the fan to drive the gas at the air inlet 102 into the air guide tube 12, thereby increasing the air pressure inside the air guide tube 12.

[0057] The pressure sensor 5 is used to detect the air pressure in the air guide chamber 121 and send the air pressure signal in the air guide chamber 121 to the controller 16. The piezoelectric sensor 6 is used to detect the pressure of the air path blocking assembly 185 and transmit the pressure signal to the controller 16 to determine whether the airflow sensor 183 is sealed. The controller 16 is used to control the operation of the first seal 2, the air supply 4, the atomizing assembly 13, and the temperature regulating assembly 14. The controller 16 is also used to control the operation of the temperature regulating assembly 14 according to the air pressure signal.

[0058] In this embodiment, the controller 16 may include a microcontroller or a programmable logic array, etc. A piezoelectric sensor 6 is mounted on the lower surface of the sealed top cover 181; preferably, the piezoelectric sensor 6 is a piezoelectric thin-film sensor. Preferably, the controller 16 is electrically connected to a buzzer (not shown) and a capacitor (not shown), the buzzer being used to send alarm information. The capacitor is located inside the first suction tube 117 and is used to detect the remaining amount of atomized liquid in the first suction tube 117. The capacitor includes a first electrode and a second electrode, which are positioned opposite each other and located inside the first suction tube 117.

[0059] Please see Figure 6The present invention also discloses a control method for the above-mentioned leak-proof electronic atomizer, comprising the following steps:

[0060] S1. Obtain the sealing signal of the second sealing element 3 and the sealing body 1;

[0061] Before transportation, the second seal 3 is inserted into the mist outlet 103 of the suction nozzle 114 to seal the body 1. At this time, the first magnet 32 ​​inside the second seal 3 is coupled with the Hall sensor 186 of the body 1. Then the Hall sensor 186 sends the sealing signal to the controller 16, and the controller 16 obtains the sealing signal of the second seal 3 sealing the body 1.

[0062] S2. Based on the sealing signal, control the air supply component 4 to supply air to the air chamber 121;

[0063] In this embodiment, the air supply component 4 is a fan. After the controller 16 obtains the sealing signal of the second sealing component 3 sealing body 1, it controls the fan to work, so that the fan drives the gas at the air inlet 102 into the air guide pipe 12 to increase the air pressure in the air guide pipe 12.

[0064] S3. When the air supply component 4 has been working for a preset time, control the first sealing component 2 to seal the air inlet 102.

[0065] The controller 16 controls the fan to work for a preset time, which increases the air pressure in the air guide chamber 121. Then, it controls the first seal 2 to seal the air inlet 102. That is, it controls the second motor 21 to drive the second elastic sealing sheet 22 to rotate, so that the second elastic sealing sheet 22 covers the air outlet of the air inlet 102. This makes the air pressure in the air guide chamber 121 greater than the air pressure in the liquid storage chamber 101, preventing the atomized liquid in the liquid storage chamber 101 from leaking out of the liquid guide hole 1211.

[0066] S4. Obtain the air pressure in the air guide chamber 121;

[0067] The air pressure sensor 5 detects the air pressure in the air guide chamber 121 inside the air guide tube 12 in real time and sends the air pressure signal in the air guide chamber 121 to the controller 16.

[0068] S5. If the air pressure in the air guide chamber 121 is less than the preset value and the chamber is in transport state, the temperature regulation component 14 is controlled to heat the air in the air guide chamber 121 and cool the atomized liquid in the liquid storage chamber 101.

[0069] During transportation, if the air pressure in the air guide chamber 121 is lower than the preset value, air leakage may occur, meaning gas may slightly leak from the first seal 2 and the second seal 3. Therefore, the controller 16 controls the temperature regulation component 14 to heat the air in the air guide chamber 121 and cool the atomized liquid in the liquid storage chamber 101, thereby increasing the air pressure in the air guide chamber 121 while decreasing the air pressure in the liquid storage chamber 101, thus effectively solving the risk of liquid leakage caused by air leakage. It is understood that when the air in the air guide chamber 121 is heated, the first seal 2 and the second seal 3 expand due to heat, thereby improving the sealing performance and preventing air leakage and subsequent oil leakage.

[0070] In one embodiment of the present invention, the following step is further included after step S5:

[0071] S6. Obtain the separation signal that the second seal 3 is disconnected from the body 1;

[0072] Before the user inhales, the second seal 3 is removed from the mouthpiece 114, which decouples the first magnet 32 ​​from the Hall sensor 186, and the controller 16 then obtains a separation signal indicating that the second seal 3 is disconnected from the body 1.

[0073] S7. Based on the separation signal, detect whether a smoking start signal generated when the user smokes is received;

[0074] The airflow sensor 183 is used to detect whether the user is inhaling. When the user inhales, the airflow sensor 183 sends an inhalation start signal to the controller 16.

[0075] S8. When the inhalation start signal is detected, the atomizing component 13 is controlled to work, and the temperature regulating component 14 is controlled to cool the aerosol in the air delivery chamber 121 and heat the atomizing liquid in the liquid storage chamber 101.

[0076] When the user inhales, the temperature control component 14 cools the aerosol in the air guide chamber 121 to lower its temperature. This reduces the temperature difference between the aerosol and the mouthpiece 114, significantly decreasing condensation in the mist outlet 103 and lowering the probability of the user inhaling condensate. Simultaneously, the temperature control component 14 heats the atomizing liquid in the storage chamber 101, preventing splattering caused by excessive temperature difference when the atomizing component 13 atomizes the liquid.

[0077] In one embodiment of the present invention, the following steps are included before step S4:

[0078] Detect whether a smoking start signal generated when the user inhales is received;

[0079] When the inhalation start signal is detected, it is checked whether the second seal 3 is inserted at the mist outlet 103. When the second seal 3 is still inserted at the mist outlet 103, the atomizing component 13 is controlled to stop working and an alarm signal is issued.

[0080] If the second seal 3 is still inserted at the mist outlet 103 and receives the suction start signal from the airflow sensor 183, it indicates that the sealing performance of the first seal 2 or the second seal 3 is poor, and there is air leakage. Therefore, this technology allows for automatic detection of the sealing performance of the invention before transportation, eliminating the need for additional testing tools, reducing costs, and improving efficiency.

[0081] In one embodiment of the present invention, the following step is further included after step S8:

[0082] When the remaining amount of atomized matrix in the first suction tube 117 is greater than the first preset value but less than the second preset value, the control driver 152 drives the pressure ring 151 to move upward to squeeze the second suction tube 118.

[0083] When the remaining amount of atomized matrix in the first suction tube 117 is greater than the first preset value but less than the second preset value, it indicates that the remaining amount is insufficient for long-term liquid supply and the atomized matrix needs to be replenished promptly. At this time, the controller 16 controls the driver 152 to drive the pressure ring 151 upward a preset distance to squeeze the second suction tube 118, thereby allowing the atomized matrix in the second suction tube 118 to flow into the first suction tube 117. It is understood that the magnitudes of the first and second preset values ​​can be set according to the type of atomizing liquid and are not specifically limited here.

[0084] In one embodiment of the present invention, the following steps are included before step S2:

[0085] Based on the sealing signal, detect whether the airflow sensor 183 is sealed;

[0086] When the airflow sensor 183 is detected to be unsealed, a signal indicating misinstallation of the seal is issued.

[0087] In other words, during production, after the second seal 3 is inserted into the mist outlet 103 of the main body 1, the Hall sensor 186 detects the coupling signal of the first magnet 32, but the piezoelectric sensor 6 does not detect the pressure signal of the air passage barrier 1851, indicating that the second seal 3 is incompatible with the main body 1. Therefore, this technique can effectively identify whether the operator has mistakenly installed the second seal 3.

[0088] In summary, before transportation, the manufacturer seals the mist outlet 103 of the main body 1 with the second seal 3. The controller 16 automatically controls the air supply component 4 to supply air to the air chamber 121 according to the sealing signal, ensuring that the air pressure in the air chamber 121 is not less than the air pressure in the liquid storage chamber 101. When the air pressure in the air chamber 121 is less than a preset value, the temperature regulating component 14 is controlled to heat the air in the air chamber 121 and cool the atomized liquid in the liquid storage chamber 101. Therefore, leakage is effectively prevented during transportation. When the user needs to inhale, they only need to remove the second seal 3 from the mist outlet 103 to inhale normally, avoiding the problem of dry burning due to lack of atomized liquid at the start of inhalation. Therefore, this invention has the advantages of preventing leakage during transportation, compact structure, good sealing performance, small size, easy transportation, and user convenience.
