[0024] 1 is a schematic diagram of an nebulization assembly according to one embodiment of the present invention. Referring to FIG. 1, the nebulization assembly 12 can be used to heat a substrate to be nebulized to generate an aerosol. In an embodiment of the present invention, the nebulization assembly 12 can include a heating element 121, a capacitance detection module 122, and a control module 123.

[0025] The heating element 121 is used to heat the target atomization substrate to generate the aerosol. The heating element 121 may be a cylindrical heating element or a columnar heating element.

[0026] A cavity is formed inside the cylindrical heating element, and the atomization substrate is disposed in the cavity, and the atomization substrate disposed in the cavity is heated and atomized by the cylindrical heating element to generate an aerosol. Furthermore, the cylindrical heating element may include a spiral cylindrical heating wire or cylindrical heating tube, and the atomized aerosol can flow toward the atomizer base through the air passage inside the cylindrical heating element. The entire columnar heating element is columnar, and the atomization substrate is fitted on the outside of the columnar heating element, and is heated and atomized by the columnar heating element to generate an aerosol.

[0027] 2, in one embodiment of the present invention, the heating element 121 is a cylindrical heating tube, and the heating element 121 includes a cylindrical heating body 1211 and a heating cavity 1212 formed by being surrounded by the cylindrical heating body 1211, and the heating cavity 1212 is used to accommodate a substrate to be atomized that is to be heated and atomized by the heating element 121. The substrate to be atomized is disposed in the heating cavity 1212, so that when the cylindrical heating body 1211 is heated, the substrate to be atomized disposed in the heating cavity 1212 can be heated and atomized to generate an aerosol.

[0028] In some possible embodiments, as shown in Figures 3 and 4, the cylindrical heating body 1211 may further include a cylindrical base 1213 and a heating film 1214. The cylindrical base 1213 is formed to surround the heating cavity 1212. When a substrate to be atomized is placed in the corresponding heating cavity 1212 of the cylindrical base 1213, the heating film 1214 is energized, and when the heating film 1214 is energized, the substrate to be atomized in the heating cavity 1212 is heated and atomized to generate an aerosol. Note that the cylindrical base 1213 may be a metal tube made of a metal material.

[0029] The heating film 1214 is electrically connected to the power supply assembly. When the heating film 1214 is energized, it heats and atomizes the intended atomization substrate in the heating cavity 1212 to generate an aerosol.

[0030] In some embodiments, as shown in FIG. 3, the heating film 1214 is disposed on the inner surface of the cylindrical body 1213, and the cylindrical body 1213 is heated by the heating film 1214, so that after the cylindrical body 1213 is heated, the intended atomization substrate disposed in the heating cavity 1212 is heated and atomized.

[0031] In another embodiment, as shown in FIG. 4, a heating film 1214 is provided on the outer surface of the cylindrical body 1213, and the substrate to be atomized placed in the heating cavity 1212 is directly heated and atomized through the heating film 1214.

[0032] 5, the heating element 121 may be columnar and is used to heat and atomize a target atomization substrate surrounding the heating element 121. The target atomization substrate may be fitted to the outside of the heating element 121. In this way, the heating element 121 heats the target atomization substrate fitted to the heating element 121 from the inside to generate an aerosol.

[0033] 6, the heating element 121 may include a columnar base 1215 including a base body 12151 and a cavity 12152, and a heat generating member 1216 disposed in the cavity 12152 of the columnar base 1215. The heat generating member 1216 is connected to the battery assembly. The heat generating member 1216 may be a metal plate or a metal rod made of metal, and the base body 12151 may also be made of metal.

[0034] The intended atomization substrate is fitted onto the outside of the heating element 121, and the heating element 1216 is heated when energized, thereby heating the substrate body 12151 of the columnar substrate 1215, and after the substrate body 12151 is heated, it heats and atomizes the intended atomization substrate fitted onto the outside of the substrate body 12151.

[0035] 7, the heating element 121 is columnar, and includes a columnar base 1215 and a spiral heating wire 1217. The spiral heating wire 1217 is electrically connected to a power supply assembly. The to-be-atomized substrate is fitted on the outside of the heating element 121. The columnar base 1215 and the spiral heating wire 1217 may be made of metal.

[0036] The spiral heating wire 1217 is wound around the columnar substrate 1215 and is heated when electricity is applied, heating and atomizing the intended atomization substrate surrounding the spiral heating wire 1217 to generate an aerosol.

[0037] 1, in an embodiment of the present invention, the capacitance detection module 122 is electrically connected to the heating element 121 to obtain a capacitance value of the heating element 121 in real time. It is understood that when the specific configuration of the heating element 121 is different, the manner in which the capacitance detection module 122 and the heating element 121 are electrically connected will also be different.

[0038] For example, in the configuration shown in Fig. 3 or Fig. 4, the capacitance detection module 122 may be electrically connected to the cylindrical body 1213, and in the configuration shown in any of Figs. 5 to 7, the capacitance detection module 122 may be electrically connected to the columnar body 1215. The capacitance detection module 122 and the heating element 121 are electrically connected by a single wire, which simplifies the structure of the atomization assembly 12 and makes production more convenient.

[0039] In one embodiment, the heating element 121 may be connected to a power supply assembly via a pin 124 to supply power to the heating element 121. In this way, a single wire can be directly drawn from the pin 124, and the heating element 121 can be electrically connected to the capacitance detection module 122 via the single wire, so that there is no need to add other structural members or structurally modify the heating element 121 to obtain the capacitance value of the heating element 121. Those skilled in the art can select an appropriate capacitance detection circuit for the capacitance detection module 122 according to parameters such as the material and volume of the heating element 121, so a description thereof will be omitted here.

[0040] The control module 123 is a microcontroller unit (MCU) and may be electrically connected to the capacitance detection module 122. In an embodiment of the present invention, the control module 123 is used to determine whether the heating element 121 is provided with a target atomization substrate, i.e., whether a cigarette is inserted, based on the capacitance value acquired by the capacitance detection module 122.

[0041] In an embodiment of the present invention, the reference capacitance value is the capacitance value of the heating element 121 obtained by the capacitance detection module 122 when the heating element 121 is not provided with a target atomization substrate. A nominal capacitance value interval may be set based on requirements and may be obtained by the control module 123 based on the reference capacitance value, and the nominal capacitance value interval and the reference capacitance value are stored in the control module 123. The minimum value in the nominal capacitance value interval is greater than zero.

[0042] The capacitance detection module 122 obtains the capacitance value of the heating element 121 in real time and transmits the capacitance value obtained in real time to the control module 123. The control module 123 obtains the difference between the capacitance value obtained in real time and the reference capacitance value to obtain the capacitance difference. If the capacitance difference is within the nominal capacitance value range, it determines that the heating element 121 is provided with a planned atomization substrate and controls the atomization assembly 12 to start heating and atomization. However, if the capacitance difference is not within the nominal capacitance value range, it determines that the heating element 121 is not provided with a planned atomization substrate and controls the atomization assembly 12 to remain closed.

[0043] When the heating element 121 is not provided with a planned atomization substrate, the capacitance value is lower compared to when the heating element 121 is provided with a planned atomization substrate. Therefore, it is possible to determine whether the heating element 121 is provided with a planned atomization substrate based on the capacitance difference between the capacitance value acquired in real time and the reference capacitance.

[0044] The control module 123 can determine a nominal capacitance value interval based on the reference capacitance value and the specific configuration of the heating element 121, and for heating elements with the same reference capacitance value but different configurations, the corresponding nominal capacitance value intervals are different, for example, when the reference capacitance values ​​of a columnar heating element and a cylindrical heating element are the same, their nominal capacitance value intervals may be different.

[0045] In some embodiments, when it is determined that the heating element 121 is provided with a substrate to be atomized, prompt information is output to facilitate a user to operate a heating switch of the electronic atomization device based on the prompt information, and based on this operation, the electronic atomization device controls to activate the atomization assembly 12 to heat and atomize the substrate to be atomized via the heating element 121.

[0046] In another embodiment, when it is determined that the heating element 121 is provided with the substrate to be atomized, the electronic atomizer may directly control the atomization assembly 12 to operate, and heat and atomize the substrate to be atomized via the heating element 121, or when a predetermined time has elapsed since it is determined that the heating element 121 is provided with the substrate to be atomized, the electronic atomizer may directly control the atomization assembly 12 to operate, and heat and atomize the substrate to be atomized via the heating element 121. The predetermined time may be 10 seconds, 15 seconds, etc.

[0047] As described above, the control module 123 of the atomizing assembly 12 obtains the capacitance difference between the capacitance value of the heating element 121 obtained in real time and the reference capacitance value, and determines whether the heating element 121 is provided with a predetermined atomization substrate based on the relationship between the capacitance difference and the nominal capacitance value interval. Since the heating element 121 is not easily deformed, the capacitance value of the heating element 121 obtained in real time is more accurate, and the relationship between the capacitance difference and the nominal capacitance value interval can be accurately determined, and it can be accurately determined whether the heating element 121 is provided with a predetermined atomization substrate.

[0048] At the same time, the capacitance detection module 122 and the heating element 121 are electrically connected by a single wire, so that the structure of the atomization assembly is simple, which is convenient for design and production, and greatly reduces the cost of the atomization assembly.

[0049] 8 is a schematic diagram of an atomizer according to one embodiment of the present invention. Referring to FIG. 8, the atomizer 10 may include an atomizer housing 11 and an atomizing assembly 12 as described in the previous embodiments. The atomizing assembly 12 may include a heating element 121, a capacitance detection module 122, a control module 123, and a pin 124.

[0050] The atomizer housing 11 is a cylindrical structure, the inside of which may be used to place the atomizing assembly 12. The atomizer housing 11 is used to protect the atomizing assembly 12, the material of its body is made of metal or synthetic material, and its outer layer may be beautified according to the requirements of appearance, without being limited thereto, for example, a decorative layer of other material may be added.

[0051] 9 is a schematic diagram of an electronic atomizer according to an embodiment of the present invention. The electronic atomizer 1 may be used to generate an aerosol by heating a substrate to be atomized. The electronic atomizer 1 may include an atomizer 10 according to the above-mentioned embodiment, a power assembly 20 that is compatible with the atomizer 10, and an atomizer base 30 that is compatible with the atomizer 10.

[0052] The power supply assembly 20 can be used to supply power to the atomizer 10. The power supply assembly 20 can include a lithium battery and a power supply circuit. It is understood that the power supply assembly 20 can be disposed in the atomizer 10 or in the atomizer base 30, and the location of the power supply assembly 20 is not limited as long as it fits the overall structure of the product.

[0053] In some embodiments, the atomizer 10 and the atomizer base 30 are removably connected to one another by a threaded connection, and the power assembly 20 is disposed within the atomizer base 30.

[0054] It is understood that the atomizer 10 and the atomizer base 30 are not limited to being connected by threads, but may be removably connected by magnetic attraction. Furthermore, the atomizer 10, the power assembly 20, and the atomizer base 30 are not limited to being cylindrical, but may be cylindrical having an elliptical, runway-shaped, or irregularly shaped cross section.

[0055] The atomizer 10 may further include an insertion port 13 to facilitate a user inserting a substrate to be atomized into the atomizer.

[0056] The atomizer base 30 may be cylindrical, with one end connected to the atomizer 10 and the other end having an exhaust port 31. The exhaust port 31 is provided at an end of the atomizer base 30 remote from the atomizer 10 and communicates with the atomizer 10. The exhaust port 31 forms a mouthpiece for a user to inhale smoke. The exhaust port 31 may be provided with a blocking member for blocking the exhaust port 31 when the atomizer 10 is not in use to prevent foreign matter from entering the mist duct of the atomizer 10.

[0057] The atomizer 10 can be used to place, heat and atomize a substrate to be atomized, such as a solid drug, to generate and emit an aerosol.

[0058] 10 is a flow chart of a detection method for an electronic atomization device according to an embodiment of the present invention. The method is applicable to the above electronic atomization device, and includes step S10 of obtaining the capacitance value of the heating element in real time by a capacitance detection module, step S20 of obtaining the difference between the capacitance value and a reference capacitance value by a control module, and when the difference between the capacitance value and the reference capacitance value is within a nominal capacitance value range, controlling the atomization assembly to start heating atomization.

[0059] Before executing step S10, when the electronic atomization device is powered on and the heating element 121 is not provided with a planned atomization substrate, that is, when no cigarette is inserted into the atomizer housing, the capacitance detection module 122 obtains a reference capacitance value, and the capacitance detection module 122 reads the capacitance value C1, and the capacitance value C1 at this time is set as the reference capacitance value, which is the value when no cigarette is inserted. Then, the control module 123 determines a nominal capacitance value interval based on the reference capacitance value, and determines whether the heating element 121 is provided with a planned atomization substrate based on the nominal capacitance value interval.

[0060] Then, step S10 is performed to obtain the capacitance value of the heating element in real time by the capacitance detection module 122. When a cigarette is inserted into the heating element 121, the capacitance detection module 122 reads the capacitance value C2, compares C2 with the nominal capacitance value C1 when no cigarette is inserted, and obtains the difference between the capacitance value C2 and the reference capacitance value C1 by the control module 123. When the difference between the capacitance value C2 and the reference capacitance value C1 is within the nominal capacitance value interval, it determines that the intended atomization substrate, i.e., tobacco, is inserted into the atomizer housing, and controls the atomization assembly 12 to start heating and atomization. When no cigarette is inserted, the capacitance value read by the capacitance detection module 122 is C1, the difference between which is 0 from the reference capacitance value C1, and therefore the minimum value in the nominal capacitance value interval is greater than zero, i.e., the capacitance value read by the capacitance detection module 122 is not within the nominal capacitance value interval, so it can be determined that the intended atomization substrate, i.e., tobacco, is not inserted in the atomizer housing, and the atomization assembly 12 is controlled to remain closed.

[0061] In summary, according to the atomization assembly, electronic atomization device and detection method of the present invention, the control module of the atomization assembly obtains the capacitance difference between the capacitance value of the heating element and the reference capacitance value in real time, and determines whether the heating element is provided with a predetermined atomization substrate based on the relationship between the capacitance difference and the nominal capacitance value interval. Since the heating element is not easily deformed, the capacitance value of the heating element obtained in real time can be made more accurate, so that the relationship between the capacitance difference and the nominal capacitance value interval can be accurately determined, and further, it can be accurately determined whether the heating element is provided with a predetermined atomization substrate.
