Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomizer, an electronic atomization device and a control method thereof. Background Art

[0002] An electronic atomization device generally includes an atomizer and a power supply assembly. The atomizer includes a liquid storage chamber and an atomization core. The liquid storage chamber is used to store an aerosol-generating matrix, and the atomization core is used to heat and atomize the aerosol-generating matrix to generate an aerosol.

[0003] In the prior art, after the liquid storage chamber is filled with liquid, the aerosol generating matrix is ​​generally absorbed by the atomizing core, so that a certain negative pressure is generated in the liquid storage chamber to lock the aerosol generating matrix in the liquid storage chamber. However, under the condition of warm shock transportation, the temperature change will cause the pressure in the liquid storage chamber and the airway to produce a large positive pressure difference, and the positive pressure difference is easy to squeeze the aerosol generating matrix out of the liquid storage chamber, causing the aerosol generating matrix to leak at the atomizing core position; moreover, in the case of long-term suction of the large-capacity liquid storage chamber, in the later stage of suction, the space without aerosol generating matrix in the liquid storage chamber increases, and the mass of aerosol generating matrix is ​​not much left. The mass of aerosol generating matrix consumed by the user for each puff is not enough to cause the change of space. When the user puffs, the negative pressure in the liquid storage chamber is not enough to lock the aerosol generating matrix, which is easy to cause the problem of leakage of the aerosol generating matrix, and the high-value high-viscosity (viscosity under normal temperature conditions is 3000cps-5000000cps) aerosol generating matrix is ​​easily affected by ambient temperature fluctuations, and the leakage problem will cause energy waste and affect the performance of the atomizer.

[0075] The atomizer 100 is used to store the aerosol generating substrate and atomize the aerosol generating substrate to form an aerosol for the user to inhale. The atomizer 100 can be used in different fields, such as medical treatment, beauty, leisure smoking, etc. In a specific embodiment, the atomizer 100 can be used in an electronic aerosolization device to atomize the aerosol generating substrate and generate an aerosol for the smoker to inhale.

[0076] The specific structure and function of the atomizer 100 may refer to the specific structure and function of the atomizer 100 involved in the following embodiments, and the same or similar technical effects can be achieved, which will not be repeated here.

The power supply assembly 200 also includes other components such as a battery holder (not shown), an airflow sensor (not shown), etc.

[0078] See also Figures 2 to 5 , Figure 2 yes Figure 1 A simplified structural diagram of the atomizer of the electronic atomization device provided, Figure 3 yes Figure 2 A schematic diagram of the structure of the first embodiment of the atomizer is provided, Figure 4 yes Figure 3 A schematic cross-sectional view of the atomizer is provided. Figure 5 yes Figure 4 A partial enlarged schematic diagram of the atomizer is provided.

[0079] See also Figure 2The atomizer 100 includes a liquid storage chamber 11, an atomizing chamber 5, an air inlet channel 6, an air outlet channel 13, a ventilation channel 7, and an auxiliary heating assembly 8. The liquid storage chamber 11 is used to store an aerosol-generating substrate, the atomizing chamber 5 has an inlet 51 and an outlet 52, the atomizing core 2 is disposed in the atomizing chamber 5, the air inlet channel 6 is directly connected to the inlet 51 of the atomizing chamber 5, and the air outlet channel 13 is connected to the outlet 52 of the atomizing chamber 5. The ventilation channel 7 has an air inlet 71 and an air outlet 72, the air inlet 71 of the ventilation channel 7 is directly connected to the air inlet channel 6, and the air outlet 72 of the ventilation channel 7 is connected to the liquid storage chamber 11. The auxiliary heating assembly 8 is configured to heat the aerosol-generating substrate in the ventilation channel 7. In this embodiment, the aerosol generating matrix stored in the liquid storage chamber 11 is a high-viscosity working medium. Specifically, under normal temperature conditions, the viscosity of the aerosol generating matrix stored in the liquid storage chamber 11 is 3000cps-5000000cps.

[0080] It can be understood that by providing the ventilation channel 7 in the atomizer 100, the air inlet 71 of the ventilation channel 7 is connected to the air inlet channel 6, and the air outlet 72 is connected to the liquid storage chamber 11, the liquid storage chamber 11 can be ventilated to balance the air pressure in the liquid storage chamber 11. Furthermore, the ventilation channel 7 can be used as a pressure relief channel and has a certain diversion effect. Specifically, when the large-capacity liquid storage chamber 11 is inhaled for a long time and there is not much aerosol generating base remaining in the liquid storage chamber 11, the mass of the aerosol generating base consumed by the user with each puff is not enough to cause a change in space, and the negative pressure in the liquid storage chamber 11 is not enough to lock the aerosol generating matrix; or, under warm-shock transportation conditions, when the temperature change causes a large positive pressure difference between the pressure in the liquid storage chamber 11 and the pressure in the atomization chamber 5, the air pressure in the liquid storage chamber 11 can press part of the aerosol generating matrix into the ventilation channel 7, avoiding excessive leakage of the aerosol generating matrix at the position of the atomization core 2, thereby improving the leakage problem of the atomizer 100 during suction and warm-shock transportation conditions, avoiding the waste of the aerosol generating matrix, and improving the performance of the atomizer 100.

[0081] At the same time, the atomizer 100 also includes an auxiliary heating component 8, which can heat the ventilation channel 7. In this embodiment, since the aerosol generating matrix is ​​a high-viscosity working fluid, the fluidity of the high-viscosity aerosol generating matrix is ​​poor. The auxiliary heating component 8 is set in the atomizer 100 to heat the ventilation channel 7. The viscosity of the high-viscosity aerosol generating matrix in the ventilation channel 7 is reduced, and the fluidity is stronger, which can prevent the high-viscosity aerosol generating matrix from clogging the ventilation channel 7. When the user inhales or under warm-shock transportation conditions, the aerosol-generating matrix after heating and viscosity reduction can flow more smoothly in the ventilation channel 7, and the aerosol-generating matrix in the liquid storage chamber 11 can be pressed into the ventilation channel 7 more quickly. The diversion effect of the ventilation channel 7 is stronger, and the leakage of the aerosol-generating matrix at the position of the atomizer core 2 can be more effectively avoided; moreover, the ventilation channel 7 has a ventilation function. During the ventilation process, the aerosol-generating matrix in the ventilation channel 7 is heated by the auxiliary heating component 8, and the aerosol-generating matrix after heating and viscosity reduction can also flow back to the liquid storage chamber 11 smoothly. The external atmosphere can enter the liquid storage chamber 11 through the ventilation channel 7, thereby ensuring the ventilation effect and avoiding the waste of the aerosol-generating matrix.

[0082] In some embodiments, the ventilation channel 7 is not directly connected to the atomizing chamber 5, and the ventilation threshold of the ventilation channel 7 is less than the ventilation threshold of the atomizing core 2. It can be understood that the ventilation channel 7 is not directly connected to the atomizing chamber 5, so that the ventilation channel 7 can be independent of the atomizing chamber 5, so that the aerosol generating substrate that is depressurized and enters the ventilation channel 7 will not directly enter the atomizing chamber 5 and cause leakage. The ventilation threshold of the ventilation channel 7 is less than the ventilation threshold of the atomizing core 2, so that the resistance of the aerosol generating substrate in the liquid storage chamber 11 when flowing to the ventilation channel 7 is less than the resistance when flowing to the position of the atomizing core 2, which makes it easier for the aerosol generating substrate in the liquid storage chamber 11 to flow into the ventilation channel 7, thereby more effectively avoiding the leakage of the aerosol generating substrate from the position of the atomizing core 2.

[0083] In some embodiments, the cross-sectional size of the airway where the air inlet 71 of the ventilation channel 7 is located is smaller than the cross-sectional size of the atomizing chamber 5. It can be understood that, under the condition of the same air flow rate, the smaller the cross-sectional size of the airway where the air inlet 71 is located, the faster the flow rate of the airflow, and the greater the absolute value of the negative pressure around the air inlet 71 of the ventilation channel 7. Setting the cross-sectional size of the airway where the air inlet 71 of the ventilation channel 7 is located to be smaller than the cross-sectional size of the atomizing chamber 5 can make the pressure at the position of the air inlet 71 of the ventilation channel 7 lower than the pressure of the atomizing chamber 5 during the inhalation process, which is more conducive to enhancing the diversion effect of the ventilation channel 7 and promoting the flow of the high-viscosity aerosol generating matrix in the ventilation channel 7, thereby more effectively improving the suction leakage problem of the nebulizer 100.

[0084] When the user inhales, the pressure at the position of the air inlet 71 of the ventilation channel 7 is lower than the pressure of the atomizing chamber 5. Preferably, the pressure difference between the air inlet 71 of the ventilation channel 7 and the atomizing chamber 5 under the suction condition is 200Pa-500Pa. It can be understood that setting the pressure difference between the air inlet 71 of the ventilation channel 7 and the atomizing chamber 5 within the above range can not only ensure that the suction resistance of the atomizer 100 is within a suitable range and ensure smooth suction, but also make the air inlet 71 of the ventilation groove better promote the flow of the high-viscosity aerosol generating matrix in the ventilation channel 7, avoid the pressure difference between the two being too large, resulting in the atomizer 100 having too large aspiration resistance, and then causing the problem of difficulty in suction, and also avoid the pressure difference being too small, resulting in the air inlet 71 of the ventilation channel 7 losing the function of promoting the flow of the high-viscosity aerosol generating matrix in the ventilation channel 7. In a specific embodiment, under the suction condition, the pressure in the atomization chamber 5 is -500 Pa, the pressure at the air inlet 71 of the ventilation channel 7 is -800 Pa, and the pressure difference between the air inlet 71 of the ventilation channel 7 and the atomization chamber 5 is 300 Pa.

[0085] In some embodiments, the equivalent diameter of the ventilation channel 7 is in the range of 0.5-1.2 mm, which can make the ventilation channel 7 better realize the ventilation function and more effectively avoid the leakage of the aerosol generating matrix. The length of the ventilation channel 7 can be designed according to the volume of the liquid storage chamber 11 and the allowable temperature difference. The larger the volume of the liquid storage chamber 11 and the larger the allowable temperature difference, the longer the ventilation channel 7 can be.

[0086] Specifically, the auxiliary heating component 8 can be arranged in the ventilation channel 7, so as to directly heat the aerosol generating matrix in the ventilation channel 7 through the auxiliary heating component 8. For example, the auxiliary heating component 8 can be arranged as a magnetic induction heating element, and the auxiliary heating component 8 generates heat by magnetic induction, thereby heating the aerosol generating matrix; or, the auxiliary heating component 8 can also be arranged around the ventilation channel 7 to heat the aerosol generating matrix in the ventilation channel 7; or, the auxiliary heating component 8 can also be attached to the side wall of the ventilation channel 7, or embedded in the side wall of the ventilation channel 7, and by heating the side wall of the ventilation channel 7, the heat of the side wall of the ventilation channel 7 is transferred to the aerosol generating matrix in the ventilation channel 7, thereby heating the aerosol generating matrix in the ventilation channel 7 and reducing the viscosity of the aerosol generating matrix. The auxiliary heating component 8 can also be arranged at other positions, as long as the auxiliary heating component 8 heats the aerosol generating matrix in the ventilation channel 7. The specific setting position can be designed as needed, and this application does not limit this.

[0087] When the user inhales, the liquid storage chamber 11 serves as a pressure source, and the two pressure outlets are the ventilation channel 7 and the atomizer core 2 respectively. The pressure in the liquid storage chamber 11 presses a portion of the aerosol generating matrix into the atomizer core 2 for atomization, and the auxiliary heating component 8 heats the ventilation channel 7, thereby rapidly reducing the viscosity of the aerosol generating matrix in the ventilation channel 7, making it easier to press the high-viscosity aerosol generating matrix into the ventilation channel 7 more quickly, thereby avoiding excessive leakage of the aerosol generating matrix near the atomizer core 2. The diversion effect of the ventilation channel 7 avoids leakage at the atomizer core 2 during inhalation or under warm shock transportation conditions.

[0088] In one embodiment, when the user stops inhaling, the liquid storage chamber 11 will preferentially press the high-viscosity aerosol-generating matrix into the ventilation channel 7 for the pressure increase in the liquid storage chamber 11 caused by the increase in ambient temperature. The volume of the gas in the liquid storage chamber 11 increases, which can reduce the pressure in the liquid storage chamber 11, thereby reducing the negative pressure during the next inhalation, and further reducing the risk of leakage during inhalation, thereby improving the leakage problem caused by the influence of temperature changes on the pressure in the liquid storage chamber 11. In another embodiment, when the user stops inhaling, the temperature of the gas in the liquid storage chamber 11 decreases, the pressure in the liquid storage chamber 11 decreases, and the atmospheric pressure presses the high-viscosity aerosol-generating matrix in the ventilation channel 7 back into the liquid storage chamber 11, thereby avoiding the waste of the aerosol-generating matrix.

[0089] In this embodiment, the auxiliary heating assembly 8 only includes the first auxiliary heating element 82, which is a heat conductor. The first auxiliary heating element 82 is configured to heat the aerosol generating matrix in the ventilation channel 7 by conducting the heat of the atomizing core 2. It can be understood that in this embodiment, the heat of the atomizing core 2 is directly conducted to the ventilation channel 7 by the first auxiliary heating element 82, and the heat source of the first auxiliary heating element 82 is the atomizing core 2. There is no need to set a separate heat source, which can simplify the structure and reduce costs. The heat generated by the atomizing core 2 is transferred to the ventilation channel 7, which can heat the aerosol generating matrix in the ventilation channel, reduce the viscosity of the aerosol generating matrix, avoid the high viscosity of the aerosol generating matrix blocking the ventilation channel 7, and improve the fluidity of the aerosol generating matrix. When the user inhales, the flow rate of the aerosol generating matrix in the ventilation channel 7 can be increased, reducing the risk of leakage from the position of the atomizing core 2.

[0091] For details, see Figures 3 to 5 In this embodiment, the atomizer 100 includes a shell 1, a top seat 9, an atomizing core 2 and a base 10. The shell 1 has an air outlet pipe 12 inside, and the air outlet pipe 12 is surrounded to form an air outlet channel 13. The top seat 9 is arranged in the shell 1, and cooperates with the shell 1 to form a liquid storage chamber 11. The top seat 9 has a liquid inlet hole 91. Specifically, the side wall of the top seat 9 has two liquid inlet holes 91, and the top seat 9 has an atomizing chamber 5 inside. The atomizing core 2 is arranged in the atomizing chamber 5, and the atomizing core 2 is fluidically connected to the liquid storage chamber 11 through the liquid inlet hole 91. The aerosol generating matrix in the liquid storage chamber 11 is absorbed by the atomizing core 2, and is atomized to generate aerosol under heating conditions. The aerosol generated by atomization flows to the air outlet channel 13 through the atomizing chamber 5, and is finally inhaled by the user. In a specific embodiment, Figure 4 As shown, the atomizer core 2 is in a circular tube shape. When the aerosol generating matrix enters the central pipe of the atomizer core 2 through two liquid inlet holes 91, the inner surface of the atomizer core 2 is the liquid absorption surface, and the outer surface is the atomization surface. The liquid absorption surface absorbs the aerosol generating matrix and transmits it to the atomization surface through the pores inside the atomizer core 2 to be heated and atomized. In other embodiments, the atomizer core 2 can also be set to other shapes and can be designed as needed.

[0092] See also Figure 4 and Figure 5 In some embodiments, the top seat 9 cooperates with the shell 1 to form a first ventilation sub-channel 74, the first auxiliary heating element 82 is disposed on the top seat 9 and is disposed in contact with the atomizer core 2, the thermal conductivity of the first auxiliary heating element 82 is greater than the thermal conductivity of the top seat, and the first auxiliary heating element 82 conducts the heat of the atomizer core 2 to heat the aerosol-generating matrix in the first ventilation sub-channel 74. It can be understood that since the first auxiliary heating element 82 is disposed on the top seat 9, the thermal conductivity of the first auxiliary heating element 82 is set to be greater than the thermal conductivity of the top seat 9, so that more heat of the atomizer core 2 can be conducted to the first ventilation sub-channel 74 via the first auxiliary heating element 82, and the heat of the atomizer core 2 is prevented from being conducted to the top seat 9, which is conducive to reducing heat loss.

[0093] In some embodiments, the first auxiliary heating element 82 is a metal layer, which may be a gold-plated layer formed by electroplating or the like, and the material of the first auxiliary heating element 82 may be a metal material with high thermal conductivity such as gold-plated, silver, copper, aluminum, etc., and the material of the top seat 9 may be other materials with low thermal conductivity such as resin and plastic. The atomizer core 2 includes a liquid-conducting substrate 21 and a heating element 22 disposed on the liquid-conducting substrate 21, and the first auxiliary heating element 82 is disposed in contact with the liquid-conducting substrate 21 of the atomizer core 2, thereby conducting the heat of the atomizer core 2 to the first ventilation sub-channel 74.

[0094] See also Figures 5 to 7 In a specific embodiment, a groove 92 is provided on the outer side of the top seat 9, one end of the groove 92 is connected to the liquid inlet hole 91, and the groove 92 cooperates with the inner surface of the shell 1 to form a first ventilation sub-channel 74, one end of the first ventilation sub-channel 74 is connected to the liquid storage chamber 11, and the other end is connected to the atmosphere. The first auxiliary heating element 82 is at least partially disposed on the groove surface of the groove 92 and the hole wall of the liquid inlet hole 91. Specifically, the first auxiliary heating element 82 can be partially disposed on the side surface of the groove 92, can also be disposed on the bottom surface of the groove 92, or can be disposed on both the side surface and the bottom surface of the groove 92.

[0095] See also Figures 3 to 7 In some embodiments, the liquid-conducting base 21 of the atomizing core 2 is tubular, and the heating element 22 is disposed on the outer peripheral side of the liquid-conducting base 21. Specifically, the heating element 22 can be a metal heating element such as a heating wire, a heating sheet or a heating net, and the heating element 22 is disposed around the outer peripheral side of the liquid-conducting base 21. Along the axial direction of the liquid-conducting base 21, the opposite ends of the liquid-conducting base 21 are correspondingly embedded in the liquid inlet hole 91, and are disposed in contact with a portion of the first auxiliary heating element 82 disposed on the hole wall of the liquid inlet hole 91.

[0096] By embedding the two ends of the liquid-conducting substrate 21 in the liquid inlet hole 91, the first auxiliary heating element 82 of a part of the hole wall of the liquid inlet hole 91 is arranged in contact with the liquid-conducting substrate 21, so that the heating element 22 of the atomizer core 2 generates heat when powered, and the heat is transferred to the liquid-conducting substrate 21, and then transferred from the liquid-conducting substrate 21 to the first auxiliary heating element 82. Since the first auxiliary heating element 82 is partially arranged on the groove surface of the groove 92, the first auxiliary heating element 82 is a metal layer with a relatively high thermal conductivity coefficient, and the portion of the first auxiliary heating element 82 arranged on the hole wall of the liquid inlet hole 91 can transfer the heat of the atomization core 2 to the portion of the first auxiliary heating element 82 arranged on the groove surface of the groove 92, so that the first ventilation sub-channel 74 is directly heated by the portion of the first auxiliary heating element 82 arranged on the groove surface of the groove 92, and then the aerosol generating matrix in the first ventilation sub-channel 74 is heated, the viscosity of the aerosol generating matrix is ​​reduced, the fluidity is improved, and the high viscosity aerosol generating matrix is ​​prevented from clogging the first ventilation sub-channel 74, the diversion effect of the first ventilation sub-channel 74 is improved, and the risk of leakage of the aerosol generating matrix from the atomization core 2 is effectively reduced.

[0097] like Figure 5 and Figure 6 As shown, in a specific embodiment, the side wall of the top seat 9 is only provided with a groove 92, and the groove 92 cooperates with the inner surface of the shell 1 to form a first ventilation sub-channel 74, and the first auxiliary heating element 82 is only partially provided on the hole wall of one liquid inlet hole 91, and the liquid inlet hole 91 is connected to the groove 92, and the hole wall of the other liquid inlet hole 91 is not provided with the first auxiliary heating element 82. The liquid-conducting substrate 21 is correspondingly embedded in the opposite ends of the liquid inlet hole 91, and only one end is arranged in contact with the first auxiliary heating element 82 provided on the hole wall of the liquid inlet hole 91 to heat the first ventilation sub-channel 74.

[0098] In other embodiments, two first ventilation sub-channels 74 may also be formed, that is, the side wall of the top seat 9 may be provided with two grooves 92, and the two grooves 92 are connected to the two liquid inlet holes 91 in a one-to-one manner. The auxiliary heating assembly may include two first auxiliary heating elements 82, and the two first auxiliary heating elements 82 are arranged in a one-to-one manner on the hole walls of the two liquid inlet holes and the groove surfaces of the two grooves, so that the opposite ends of the liquid-conducting substrate 21 embedded in the liquid inlet hole 91 can be fitted with the first auxiliary heating elements 82, so that the two first auxiliary heating elements 82 can transfer the heat of the atomization core 2 to the first ventilation sub-channel 74, so as to further enhance the diversion effect of the first ventilation sub-channel 74, more quickly increase the temperature of the aerosol generating matrix, reduce the viscosity of the aerosol generating matrix, and more effectively avoid the leakage problem at the position of the atomization core 2.

[0099] For further information, see Figures 3 to 7In some embodiments, the first auxiliary heating element 82 may also be disposed on a portion of the outer surface of the top seat 9 located on a side of the liquid inlet hole 91 away from the groove 92 .

[0100] Specifically, Figure 6 and Figure 7 As shown, the top seat 9 includes a cylindrical section 93, a truncated cone section 94 and a connecting section 95 connected to each other. The connecting section 95 is connected to the side of the truncated cone section 94 away from the cylindrical section 93. The cylindrical section 93 and the truncated cone section 94 have an atomizing chamber 5 inside. One end of the connecting section 95 away from the cylindrical section 93 is connected to the air outlet pipe 12 so that the atomizing chamber 5 is connected to the air outlet channel 13. The outer side surface of the cylindrical section 93 is fitted with the inner surface of the shell 1 to form a liquid storage chamber 11 with the shell 1. The truncated cone section 94 is located in the liquid storage chamber 11. The outer side surface of the truncated cone section 94 can play a certain role in guiding the flow, so that the aerosol generating matrix in the liquid storage chamber 11 flows more smoothly to the position of the liquid inlet hole 91 and the first ventilation sub-channel 74. The groove 92 is arranged on the outer side of the cylindrical section 93, the liquid inlet hole 91 is arranged on the side wall of the cylindrical section 93, and is located on the side of the groove 92 close to the truncated cone section 94. The side wall of the truncated cone section 94 is provided with a cut surface 941 corresponding to the position of the liquid inlet hole 91 and the groove 92, and the first auxiliary heating element 82 is partially arranged on the cut surface 941 of the truncated cone section 94. It can be understood that by arranging part of the first auxiliary heating element 82 on the cut surface 941, the area of ​​the first auxiliary heating element 82 can be increased, and the thermal conductivity of the first auxiliary heating element 82 can be improved. The first auxiliary heating element 82 arranged on the cut surface 941 can also heat part of the aerosol generating matrix close to the first ventilation sub-channel 74 in the liquid storage chamber 11, reduce the viscosity of the aerosol generating matrix, and enhance the fluidity of the aerosol generating matrix, so that the aerosol generating matrix in the liquid storage chamber 11 can more easily enter the first ventilation sub-channel 74, and more effectively improve the leakage problem at the position of the atomization core 2.

[0101] See also Figures 3 to 9, the base 10 is connected to the end of the top seat 9 away from the air outlet pipe 12. Specifically, in some embodiments, the base 10 is annular, and the end of the base 10 close to the air outlet pipe 12 is located in the shell 1, and cooperates with the shell 1 to form a second ventilation sub-channel 73, one end of the second ventilation sub-channel 73 is connected to the first ventilation sub-channel 74, and then connected to the liquid storage chamber 11 through the first ventilation sub-channel 74, and the other end of the second ventilation sub-channel 73 is connected to the atmosphere, so that the second ventilation sub-channel 73 and the first ventilation sub-channel 74 together form the ventilation channel 7. In other embodiments, the ventilation channel 7 may also include only one ventilation sub-channel, for example, the ventilation channel 7 may include only the first ventilation sub-channel 74, but not the second ventilation sub-channel 73, and the other end of the first ventilation sub-channel 74 is directly connected to the atmosphere, or the ventilation channel 7 may also include other numbers of ventilation sub-channels.

[0102] like Figure 5 As shown, in a specific embodiment, at least part of the outer side surface of the base 10 is spaced apart from the inner surface of the shell 1 to form a second ventilation sub-channel 73. Specifically, the second ventilation sub-channel 73 is annular, one end of the second ventilation sub-channel 73 is connected to the first ventilation sub-channel 74, and the other end is connected to the atmosphere through the air inlet 71 of the ventilation channel 7.

[0103] Specifically, the base 10 has a accommodating channel 101 inside, one end of the accommodating channel 101 is connected to the atomizing chamber 5, and the other end is connected to the atmosphere. In a specific embodiment, the accommodating channel 101 serves as the air inlet channel 6, and the side wall of the base 10 is provided with a ventilation hole 102, one end of the ventilation hole 102 is connected to the accommodating channel 101, and the other end is connected to the second ventilation sub-channel 73, and the ventilation hole 102 serves as the air inlet 71 of the ventilation channel 7. The external atmosphere enters the liquid storage chamber 11 through the accommodating channel 101, the ventilation hole 102, the second ventilation sub-channel 73 and the first ventilation sub-channel 74 in sequence to achieve ventilation for the liquid storage chamber 11. In other embodiments, the second ventilation sub-channel 73 may not be provided, and the other end of the first ventilation sub-channel 74 may be directly connected to the ventilation hole 102 or the accommodating channel 101 or the external atmosphere.

[0104] In other embodiments, the second ventilation sub-channel 73 may also be formed in other ways. Specifically, the second ventilation sub-channel 73 may be directly formed in the base 10. For example, the ventilation hole 102 may be set as a blind hole, and the second ventilation sub-channel 73 may be a through hole set on the side wall of the base 10, one end of the through hole is connected to the ventilation hole 102, and the other end is connected to the first ventilation sub-channel 74 of the base 10. The second ventilation sub-channel 73 is formed directly through the through hole set on the side wall of the base 10; or, the side wall of the base 10 may also be arranged in affixed with the inner surface of the shell 1, and a groove is set on the inner surface of the shell 1, and the second ventilation sub-channel 73 is formed by the groove on the inner surface of the shell 1 and the side wall of the base 10; or, a groove may also be set on the outer side surface of the base 10, and the groove on the outer side surface of the base 10 and the inner surface of the shell 1 form the second ventilation sub-channel 73. The specific arrangement of the second ventilation sub-channel 73 can be designed as needed, and the present application does not limit this.

[0105] In other embodiments, the first ventilation sub-channel 74 may also be directly formed inside the top seat 9. For example, the first ventilation sub-channel 74 may be directly a through hole provided on the side wall of the top seat 9, one end of the through hole is connected to the liquid storage chamber 11, and the other end is connected to the second ventilation sub-channel 73, so that the second ventilation sub-channel 73 is connected to the first ventilation sub-channel 74; or, a groove may be provided on the inner surface of the shell 1, and the first ventilation sub-channel 74 is formed by the groove on the inner surface of the shell 1 and the side wall of the top seat 9; or, the first ventilation sub-channel 74 may be directly formed inside the shell 1. The specific setting method of the first ventilation sub-channel 74 can be designed as needed, and the present application does not limit this, as long as one end of the first ventilation sub-channel 74 is connected to the liquid storage chamber 11, and the other end is connected to the second ventilation sub-channel 73, and the first auxiliary heating element 82 can heat the aerosol generation matrix in the first ventilation sub-channel 74.

[0106] In some embodiments, Figure 4 and Figure 5As shown, the atomizer 100 also includes a seal 3, which is arranged in the atomizing chamber 5 inside the top seat 9. Specifically, one end of the base 10 close to the air outlet pipe 12 is embedded in the top seat 9, and the seal 3 is partially located between the atomizing core 2 and the end of the base 10 close to the air outlet pipe 12, and partially embedded in the accommodating channel 101 of the base 10. The seal 3 can be a sealing material such as silicone and rubber. It can be understood that the seal 3 is arranged between the atomizing core 2 and the base 10, and the atomizer 100 can be sealed to prevent the leakage of the aerosol generating matrix at the contact position between the atomizing core 2 and the base 10. At the same time, the ventilation channel 7 is not in direct contact with the atomizing core 2, and the ventilation channel 7 plays a better role in diversion. Under warm shock transportation conditions or when the user inhales, the aerosol generating matrix in the liquid storage chamber 11 can smoothly enter the ventilation channel 7, reducing the risk of leakage of the aerosol generating matrix at the position of the atomizing core 2.

[0107] The seal 3 has a central hole 31 therein, which is connected to the accommodating channel 101. The central hole 31 serves as a part of the atomizing chamber 5. The port at one end of the central hole 31 of the seal 3 away from the atomizing core 2 serves as the entrance 51 of the atomizing chamber 5. The aperture of the central hole 31 of the seal 3 is larger than the aperture of the ventilation hole 102, so that the cross-sectional dimension of the atomizing chamber 5 is much larger than the cross-sectional dimension at the position of the air inlet 71 of the ventilation channel 7, so that the pressure at the air inlet 71 of the ventilation channel 7 is lower than the pressure of the atomizing chamber 5, which is more conducive to promoting the flow of the aerosol generating matrix in the ventilation channel 7 and effectively improving the leakage problem of the atomizer 100.

[0108] See also Figure 4 and Figure 5 In this embodiment, the base 10 is annular, and one end of the base 10 away from the air outlet pipe 12 is located outside the housing 1. The base 10 is made of metal, and the base 10 serves as the first electrical connector of the atomizer 100. The atomizer 100 also includes a conductive ring 4, which is arranged inside the base 10 and insulated from the base 10, so that the conductive ring 4 serves as the second electrical connector. Specifically, the conductive ring 4 is arranged in the accommodating channel 101 at one end of the base 10 away from the atomizing core 2, and the conductive ring 4 is annular, and the conductive ring 4 is spaced apart from the inner surface of the base 10. The atomizer 100 also includes an insulating member 20, which is arranged in the accommodating channel 101 and is located between the inner surface of the base 10 and the conductive ring 4, so that the base 10 is insulated from the conductive ring 4 to avoid short circuit. In a specific embodiment, the insulating member 20 is annular, embedded between the inner surface of the base 10 and the outer surface of the conductive ring 4, and the insulating member 20 can fix the conductive ring 4 in the accommodating channel 101.

[0109] In some embodiments, the power supply assembly 200 further includes a control circuit 201, which is used to control the auxiliary heating assembly 8 to start heating in response to detecting a start signal, so as to heat the aerosol generating substrate in the ventilation channel 7. The start signal may include a suction negative pressure; and is used to control the auxiliary heating assembly 8 to stop heating in response to detecting that the suction is stopped, so as to end the heating of the aerosol generating substrate in the ventilation channel 7.

[0110] Specifically, in the present embodiment, since the auxiliary heating assembly only includes the first auxiliary heating element 82, and the first auxiliary heating element 82 heats the aerosol generating substrate in the ventilation channel 7 by conducting the heat of the atomizer core 2, the first auxiliary heating element 82 is only a heat conductor and not a heat source. Therefore, in the present embodiment, in response to detecting the start signal, the control circuit 201 controls the auxiliary heating assembly 8 to start heating, that is, controls the atomizer core 2 to start heating, so that the first auxiliary heating element 82 conducts the heat of the atomizer core 2 to the aerosol generating substrate in the ventilation channel 7; in response to detecting the cessation of inhalation, the control circuit 201 controls the auxiliary heating assembly 8 to stop heating, that is, controls the atomizer core 2 to stop heating, thereby terminating the heating of the aerosol generating substrate in the ventilation channel 7.

[0111] See also Figures 11 to 15 , Fig.11 yes Figure 2 A cross-sectional schematic diagram of a second embodiment of the atomizer is provided, Fig.12 yes Fig.11 A partial enlarged schematic diagram of the atomizer provided, Fig.13 yes Fig.11 A schematic diagram of the structure of the second auxiliary heating element of the atomizer is provided, Fig.14 yes Fig.13 A schematic cross-sectional view of a second auxiliary heating element is provided, Fig.15 yes Fig.13 Another cross-sectional schematic diagram of a second auxiliary heating element is provided.

[0112] See also Fig.11The present application also provides another atomizer 100, which is different from the first embodiment of the atomizer 100 in that, in this embodiment, the auxiliary heating assembly 8 only includes a second auxiliary heating element 83, which is a heating element. The second auxiliary heating element 83 is configured to heat the aerosol-generating matrix in the ventilation channel 7 by generating heat, and the ventilation channel 7 is not directly connected to the atomizing chamber 5. By setting the second auxiliary heating element 83 as a heating element, the second auxiliary heating element 83 can be directly used as a heat source, and the heat generated by its own heating can be used to heat the ventilation channel 7, thereby reducing the viscosity of the aerosol-generating matrix in the ventilation channel 7, enhancing the fluidity of the aerosol-generating matrix in the ventilation channel 7, and avoiding leakage of the aerosol-generating matrix at the position of the atomizing core 2. In this embodiment, the auxiliary heating assembly 8 does not include the first auxiliary heating element 82, that is, the groove surface of the groove 92 of the top seat 9, the hole wall of the liquid inlet hole 91 and the cut surface 941 of the side wall of the truncated cone section 94 are not provided with a metal layer, and it is not necessary to conduct the heat of the atomizer core 2 to the ventilation channel 7 through the metal layer.

[0113] Specifically, in this embodiment, the second auxiliary heating element 83 is embedded in the accommodating channel 101 of the base 10 and is spaced apart from the atomizer core 2. Specifically, the second auxiliary heating element 83 is disposed on the side of the seal 3 away from the atomizer core 2, and the seal 3 is located between the atomizer core 2 and the second auxiliary heating element 83, so that the atomizer core 2 and the second auxiliary heating element 83 can be spaced apart to prevent heat transfer between the two. The second auxiliary heating element 83 is configured to heat the base 10 by generating heat under power-on conditions, thereby at least heating the aerosol generating substrate in the second ventilation sub-channel 73.

[0114] In this embodiment, the base 10 is made of metal. Specifically, the material of the base 10 can be a single metal such as copper, iron, or an alloy material. The second auxiliary heating element 83 is embedded in the accommodating channel 101 of the base 10, that is, the second auxiliary heating element 83 is arranged in contact with the base 10, and the second auxiliary heating element 83 is electrically connected to the power supply component 200. When powered on, it is heated, so that the base 10 arranged in contact with it can be heated. Since the base 10 cooperates with the shell 1 to form the second ventilation sub-channel 73, the second ventilation sub-channel 73 can be heated by the base 10. That is to say, in this embodiment, the base 10 is first heated by the second auxiliary heating element 83 of the auxiliary heating component 8, and then the aerosol generation matrix in the second ventilation sub-channel 73 of the ventilation channel 7 is heated by the base 10. In other embodiments, the second auxiliary heating element 83 can also be set at other positions to directly heat the aerosol generation matrix in the ventilation channel 7.

[0115] Specifically, in some embodiments, the second auxiliary heating element 83 includes a substrate 81 and a heating element (not shown) disposed on the substrate 81, the material of the substrate 81 includes ceramic, and the outer surface of the substrate 81 is in contact with the inner surface of the accommodating channel 101, so that the second auxiliary heating element 83 is embedded in the accommodating channel 101, and the heating element heats the substrate 81 under power-on conditions, and then heats the base 10 in contact with the substrate 81, so as to heat the aerosol-generating matrix in the second ventilation sub-channel 73 of the ventilation channel 7. In other embodiments, the second auxiliary heating element 83 can also be set to other structures, as long as it can heat the aerosol-generating matrix in the ventilation channel 7.

[0116] The two electrodes (not shown) of the heating element of the second auxiliary heating element 83 are electrically connected to the base 10 and the conductive ring 4 respectively, and the two pins (not shown) of the heating element 22 of the atomizer core 2 are electrically connected to the base 10 and the conductive ring 4 respectively. The base 10 and the conductive ring 4 of the atomizer 100 are electrically connected to the positive and negative electrodes of the battery of the power supply assembly 200 respectively, so that the atomizer core 2 of the atomizer 100 and the heating element of the second auxiliary heating element 83 are electrically connected to the power supply assembly 200 through the base 10 and the conductive ring 4, and then generate heat under heating conditions.

[0117] See also Figures 11 to 15 In some embodiments, the second auxiliary heating element 83 has an air cutoff hole inside, one end of which is connected to the atomizing chamber 5. Specifically, one end of the air cutoff hole is connected to the central hole 31 of the sealing member 3, and the other end is connected to the atmosphere. The air cutoff hole serves as the air inlet channel 6, and the end of the air cutoff hole close to the atomizing chamber 5 is the entrance 51 of the atomizing chamber 5, and the external gas enters the atomizing chamber 5 through the air cutoff hole. The hole wall of the air cutoff hole is provided with a through hole, which serves as the air inlet 71 of the ventilation channel 7. The other end of the second ventilation sub-channel 73 is connected to the through hole, so as to be connected to the external atmosphere, that is, the other end of the second ventilation sub-channel 73 is not directly connected to the atomizing chamber 5. By not directly connecting the other end of the second ventilation sub-channel 73 to the atomizing chamber 5, the ventilation channel 7 can be made independent of the atomizing chamber 5, so that the aerosol generating matrix that is depressurized and enters the ventilation channel 7 will not directly enter the atomizing chamber 5 and cause leakage. Specifically, one end of the ventilation hole 102 arranged on the side wall of the base 10 is connected to the second ventilation sub-channel 73, and the other end is connected to the through hole arranged on the hole wall of the cut-off hole. The second ventilation sub-channel 73 is connected to the cut-off hole (i.e., the air inlet 71 of the ventilation channel 7) through the ventilation hole 102 and the through hole on the hole wall of the cut-off hole (i.e., the air inlet 71 of the ventilation channel 7). The external air entering the cut-off hole, i.e., the air inlet channel 6, can enter the second ventilation sub-channel 73 through the air inlet 71 of the ventilation channel 7 and the ventilation hole 102 in turn.

[0118] In a specific embodiment, the cut-off hole and the through hole are both straight through holes, the aperture of the through hole is smaller than the aperture of the cut-off hole, and the aperture of the cut-off hole is smaller than the cross-sectional size of the atomizing chamber 5. Specifically, the aperture of the cut-off hole is smaller than the aperture of the central hole 31 of the seal 3, so that the cross-sectional size of the airway where the air inlet 71 of the ventilation channel 7 is located is smaller than the cross-sectional size of the atomizing chamber 5, so that the pressure in the cut-off hole is smaller than the pressure in the atomizing chamber 5. Since the ventilation channel 7 is directly connected to the cut-off hole, the ventilation threshold of the ventilation channel 7 is smaller than the ventilation threshold of the atomizing core 2, thereby making it easier for the aerosol generating matrix in the liquid storage chamber 11 to enter the ventilation channel 7, and better avoid the leakage of the aerosol generating matrix from the position of the atomizing core 2. In this embodiment, the cut-off hole, i.e., the air inlet channel 6, is directly arranged on the second auxiliary heating element 83, which can save space, simplify the structure, and thus save costs. In other embodiments, the air intake channel 6 may not be disposed on the second auxiliary heating element 83. The air intake channel 6 may be disposed independently of the second auxiliary heating element 83 and may be designed as required, which is not limited in the present application.

[0119] In some embodiments, the distance between the ventilation channel 7 and the second auxiliary heating element 83 is smaller than the distance between the ventilation channel 7 and the atomizer core 2, and the aerosol-generating substrate in the ventilation channel 7 is heated by the second auxiliary heating element 83 under power-on conditions, rather than by the atomizer core 2. In other embodiments, the distance between the second auxiliary heating element 83 and the atomizer core 2 and the ventilation channel 7 can be set arbitrarily, as long as the auxiliary heating assembly 8 can heat the aerosol-generating substrate in the ventilation channel 7.

[0120] In this embodiment, the power supply assembly 200 is electrically connected to the atomizer core 2 of the atomizer 100 and the auxiliary heating assembly 8, i.e., the second auxiliary heating element 83, respectively. The control circuit 201 of the power supply assembly 200 is used to control the auxiliary heating assembly 8, i.e., the second auxiliary heating element 83, to start heating in response to detecting a start signal, so as to heat the aerosol-generating substrate in the ventilation channel 7. The start signal may include a suction negative pressure, a key pressure, or a touch signal; and is used to control the auxiliary heating assembly 8, i.e., the second auxiliary heating element 83 to stop heating in response to detecting that the suction is stopped, so as to end heating the aerosol-generating substrate in the ventilation channel 7.

[0121] Specifically, since the start signal includes suction negative pressure, button pressure or touch signal, in some embodiments, the control circuit 201 can be used to control the second auxiliary heating element 83 to start heating after detecting the suction negative pressure, that is, after detecting that the user starts to inhale, thereby heating the aerosol generating matrix in the ventilation channel 7.

[0122] In other embodiments, the control circuit 201 can be used to control the auxiliary heating component 8, i.e., the second auxiliary heating element 83, to start heating after detecting the key pressure or touch signal. Even if the suction negative pressure is not detected, the auxiliary second auxiliary heating element 83 can be controlled to start heating. In other words, it is not necessary to detect the user's suction negative pressure. As long as the key pressure or touch signal is detected, the second auxiliary heating element 83 can be controlled to start heating. The aerosol generating matrix in the ventilation channel 7 can be preheated before the user starts to inhale, so that the ventilation channel 7 can be quickly diverted after the user starts to inhale, and the problem of liquid leakage in the atomizer 100 can be solved more quickly and efficiently. It should be noted that the key pressure or touch signal in this embodiment refers to the key pressure or touch signal that starts the auxiliary heating component 8, i.e., the second auxiliary heating element 83 to start working, and is not the key pressure or touch signal that controls the power on and off of the atomizer 100.

[0123] In one specific embodiment, the control circuit 201 can also be used to determine whether suction negative pressure is detected within a preset time after detecting key pressure or touch signal and controlling the auxiliary heating component 8 to start heating; if so, control the auxiliary heating component 8, i.e., the second auxiliary heating element 83 to continue heating, and in response to detecting the cessation of suction, control the auxiliary heating component 8, i.e., the second auxiliary heating element 83 to stop heating to end the heating of the aerosol generating matrix in the ventilation channel 7; if not, control the auxiliary heating component 8, i.e., the second auxiliary heating element 83 to stop heating to end the heating of the aerosol generating matrix in the ventilation channel 7.

[0124] It can be understood that by setting the control circuit 201 to control the atomizer 100 to work as above, the aerosol generating matrix in the ventilation channel 7 can be heated or preheated, the viscosity of the aerosol generating matrix in the ventilation channel 7 can be reduced, the fluidity of the aerosol generating matrix can be enhanced, and the diversion effect of the ventilation channel 7 can be enhanced, so that when the user inhales or under warm-shock transportation conditions, the aerosol generating matrix in the liquid storage chamber 11 can be pressed into the ventilation channel 7 more quickly, avoiding excessive leakage of the aerosol generating matrix at the position of the atomizer core 2, and the problem of easy leakage of the atomizer 100 in the prior art can be solved. At the same time, the control circuit 201 is also used to determine whether the suction negative pressure is detected within the preset time. When the suction negative pressure is not detected within the preset time, the auxiliary heating component 8, i.e., the second auxiliary heating element 83, is controlled to stop heating. This can avoid the situation where the user does not inhale within the preset time but the auxiliary heating component 8, i.e., the second auxiliary heating element 83 continues to heat, resulting in the temperature of the ventilation channel 7 being too high, the aerosol generating matrix in the ventilation channel 7 having strong fluidity, and leakage from the air inlet 71 of the ventilation channel 7. At the same time, it also avoids the energy waste caused by continuous heating of the auxiliary heating component 8, i.e., the second auxiliary heating element 83.

[0125] In this embodiment, the remaining structures of the atomizer 100 are the same as those in the first embodiment of the atomizer 100 and can achieve the same or similar technical effects, which will not be described in detail herein.

[0126] The present application also provides another atomizer 100. In this embodiment, the auxiliary heating component 8 of the atomizer 100 can include both the first auxiliary heating element 82 in the first embodiment of the atomizer 100 and the second auxiliary heating element 83 in the second embodiment of the atomizer 100, that is, in this embodiment, the auxiliary heating component 8 includes the first auxiliary heating element 82 and the second auxiliary heating element 83, which can heat the aerosol generating matrix in the first ventilation sub-channel 74 and the second ventilation sub-channel 73 at the same time, further improving the heating efficiency of the auxiliary heating component 8, so that the auxiliary heating component 8 can heat the aerosol generating matrix in the ventilation channel 7 more quickly and efficiently, reduce the viscosity of the aerosol generating matrix, enhance the fluidity of the aerosol generating matrix in the ventilation channel 7, and improve the flow rate of the aerosol generating matrix in the ventilation channel 7 under warm shock transportation conditions or when the user inhales, and more effectively improve the leakage problem at the position of the atomizer core 2 under warm shock transportation conditions or when the user inhales.

[0128] See also Fig.16 The present application also provides a control method to be applied to the electronic atomization device 300 as described above, wherein the atomizer 100 of the electronic atomization device 300 may be the atomizer 100 in any of the above embodiments, and the atomizer 100 includes an auxiliary heating component 8. Specifically, in this embodiment, the control method includes:

[0129] S1A: In response to detecting the suction negative pressure, the auxiliary heating component 8 is controlled to start heating to heat the aerosol generating substrate in the ventilation channel 7 .

[0130] Specifically, in response to detecting the negative pressure of the user's suction, that is, after the user starts to inhale, the auxiliary heating component 8 is controlled to start heating, so that the auxiliary heating component 8 heats the aerosol generating matrix in the ventilation channel 7, thereby reducing the viscosity of the aerosol generating matrix in the ventilation channel 7, enhancing the fluidity of the aerosol generating matrix, and enhancing the diversion effect of the ventilation channel 7, so that the aerosol generating matrix in the liquid storage chamber 11 can be pressed into the ventilation channel 7 more quickly.

[0131] Specifically, when the auxiliary heating component 8 only includes the first auxiliary heating element 82, in response to detecting the user's suction negative pressure, the atomizer core 2 is directly controlled to start heating, so that the heat of the atomizer core 2 is transferred to the ventilation channel 7 by the first auxiliary heating element 82; when the auxiliary heating component 8 only includes the second auxiliary heating element 83, in response to detecting the user's suction negative pressure, the second auxiliary heating element 83 is directly controlled to start heating, so that the ventilation channel 7 is heated by the second auxiliary heating element 83; when the auxiliary heating component 8 includes both the first auxiliary heating element 82 and the second auxiliary heating element 83, in response to detecting the user's suction negative pressure, the atomizer core 2 and the second auxiliary heating element 83 are controlled to start heating at the same time, so that the heat of the atomizer core 2 is transferred to the ventilation channel 7 by the first auxiliary heating element 82, and the ventilation channel 7 is directly heated by the second auxiliary heating element 83.

[0132] S2A: In response to detecting that the inhalation stops, the auxiliary heating component 8 is controlled to stop heating, so as to end the heating of the aerosol generating substrate in the ventilation channel 7 .

[0133] Specifically, in response to detecting that the user stops inhaling, the auxiliary heating component 8 is controlled to stop heating, and the auxiliary heating component 8 no longer heats the aerosol generating substrate in the ventilation channel 7.

[0134] Specifically, when the auxiliary heating component 8 only includes the first auxiliary heating element 82, in response to detecting that the user stops inhaling, the atomizer core 2 is directly controlled to stop heating, and the first auxiliary heating element 82 no longer conducts the heat of the atomizer core 2 to the ventilation channel 7; when the auxiliary heating component 8 only includes the second auxiliary heating element 83, in response to detecting that the user stops inhaling, the second auxiliary heating element 83 is directly controlled to stop heating, so as to stop the second auxiliary heating element 83 from heating the aerosol generating substrate in the ventilation channel 7; when the auxiliary heating component 8 includes both the first auxiliary heating element 82 and the second auxiliary heating element 83, in response to detecting that the user stops inhaling, the atomizer core 2 and the second auxiliary heating element 83 are controlled to stop heating at the same time, so that the first auxiliary heating element 82 and the second auxiliary heating element 83 end heating the aerosol generating substrate in the ventilation channel 7.

[0135] By controlling the atomizer 100 of the electronic atomization device 300 to work through the control method in this embodiment, the aerosol generating matrix in the ventilation channel 7 can be heated after the user starts to inhale, thereby avoiding excessive leakage of the aerosol generating matrix at the atomization core 2 position, and can solve the problem of the atomizer 100 in the prior art being prone to liquid leakage at the atomization core 2 position during inhalation or under warm-shock transportation conditions.

[0136] See also Fig.17 , Fig.17 It is a flow chart of another embodiment of the control method provided by the present application.

[0137] See also Fig.17 The present application also provides another control method to be applied to the electronic atomization device 300 as described above, wherein the atomizer 100 of the electronic atomization device 300 includes an auxiliary heating component 8, and the auxiliary heating component 8 includes a second auxiliary heating element 83. In this embodiment, the auxiliary heating component 8 may include only the second auxiliary heating element 83, or may include both the first auxiliary heating element 82 and the second auxiliary heating element 83. Specifically, in this embodiment, the control method includes:

[0138] S1Q: In response to detecting a start signal, the second auxiliary heating element 83 of the auxiliary heating assembly 8 is controlled to start heating to heat the aerosol generating matrix in the ventilation channel 7; wherein the start signal includes a key pressure or a touch signal.

[0139] Specifically, in this embodiment, the start signal includes a key pressure or a touch signal. Specifically, the key pressure or the touch signal refers to a key pressure or a touch signal that starts the auxiliary heating component 8 to start working, and is not a key pressure or a touch signal that controls the atomizer 100 to start and stop. In response to detecting the start signal, the second auxiliary heating element 83 of the auxiliary heating component 8 is controlled to start heating, so that the second auxiliary heating element 83 starts to heat the aerosol generating matrix in the ventilation channel 7, and it is not necessary to control the second auxiliary heating element 83 of the auxiliary heating component 8 to start working after detecting that the user starts to inhale.

[0140] S2Q: Determine whether suction negative pressure is detected within the preset time.

[0141] Specifically, in this embodiment, a preset time is set to determine whether the user's suction negative pressure is detected within the preset time, that is, to determine whether the user starts to inhale within a preset time period after the start signal is detected.

[0142] S21Q: If so, the auxiliary heating component 8 is controlled to continue heating, and in response to detecting that the suction has stopped, the auxiliary heating component 8 is controlled to stop heating to end the heating of the aerosol generating substrate in the ventilation channel 7.

[0143] Specifically, if the suction negative pressure is detected within the preset time, that is, if the user starts to inhale within the preset time period after the start signal is detected, the auxiliary heating component 8 is controlled to continue heating to continue heating the aerosol generating matrix in the ventilation channel 7, and when it is detected that the user stops inhaling, the auxiliary heating component 8 is controlled to stop heating to end the heating of the aerosol generating matrix in the ventilation channel 7.

[0144] Among them, when the auxiliary heating component 8 only includes the second auxiliary heating element 83, if the suction negative pressure is detected within the preset time, the second auxiliary heating element 83 is controlled to continue heating to continue heating the aerosol generating substrate in the ventilation channel 7, and when it is detected that the user stops inhaling, the second auxiliary heating element 83 is controlled to stop heating to end the heating of the aerosol generating substrate in the ventilation channel 7. When the auxiliary heating component 8 includes both the first auxiliary heating element 82 and the second auxiliary heating element 83, if the suction negative pressure is detected within the preset time, the second auxiliary heating element 83 is controlled to continue heating, so that the second auxiliary heating element 83 continues to heat the aerosol generating substrate in the ventilation channel 7, and the atomizer core 2 is controlled to start heating, and the first auxiliary heating element 82 conducts the heat of the atomizer core 2 to the aerosol generating substrate in the ventilation channel 7; and when it is detected that the user stops inhaling, the atomizer core 2 and the second auxiliary heating element 83 are controlled to stop heating at the same time to end the heating of the aerosol generating substrate in the ventilation channel 7.

[0145] S22Q: If not, the auxiliary heating component 8 is controlled to stop heating to end the heating of the aerosol generating matrix in the ventilation channel 7.

[0146] Specifically, if the suction negative pressure is not detected within the preset time, that is, within the preset time period after the start signal is detected, the user is not detected to start inhaling, that is, the user does not start inhaling, then the auxiliary heating assembly 8 is directly controlled to stop heating, that is, the second auxiliary heating element 83 is controlled to stop heating, so as to end the heating of the aerosol generating substrate in the ventilation channel 7. If the suction negative pressure is not detected within the preset time, the atomizer core 2 is controlled not to be heated.

[0147] That is to say, in this embodiment, regardless of whether the suction negative pressure is detected, as long as the start signal such as key pressure or touch signal is detected, the second auxiliary heating element 83 is controlled to start heating to preheat the ventilation channel 7, so that after the user starts to inhale, the aerosol generating matrix in the liquid storage chamber 11 can be pressed into the ventilation channel 7 more quickly, and the aerosol generating matrix 11 can be more efficiently prevented from leaking during suction of the atomizer 100. It is judged whether the suction negative pressure is detected within the preset time, and when the suction negative pressure is not detected within the preset time, the second auxiliary heating element 83 is controlled to stop heating, so as to avoid the user not inhaling within the preset time and the second auxiliary heating element 83 still continuing to heat, resulting in the temperature of the ventilation channel 7 being too high, the aerosol generating matrix in the ventilation channel 7 being highly fluid, and the problem of leakage from the air inlet 71 of the ventilation channel 7, and at the same time, it also avoids the energy waste caused by the continuous heating of the second auxiliary heating element 83.
