Description

Technical Field

[0001] This application relates to the field of aerosol generating devices, and particularly to an atomizing component, an atomizer, and an aerosol generating device. Background Technology

[0002] Common aerosol generating devices consist of an atomizer and a power supply, with the power supply connected to the bottom of the atomizer. During operation, the power supply provides power to the atomizer.

[0003] The atomizer includes a liquid reservoir and an atomizing component, with the atomizing component housed within the liquid reservoir. During operation, the aerosol-generating matrix stored in the liquid reservoir can enter the atomizing component.

[0004] As aerosol generating devices are used, the aerosol generating matrix inside the liquid storage component will be gradually consumed.

[0035] Figure 1This is a schematic diagram of an aerosol generating device. In this embodiment, the aerosol generating device refers to a device that can heat an aerosol generating matrix to a certain temperature, causing the corresponding components in the aerosol generating matrix to atomize and form an inhalable aerosol. Inhalation refers to the state of being inhaled into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose. The aerosol generating matrix refers to a product capable of forming an aerosol under heating. Aerosols may contain volatile compounds. The aerosol generating matrix can be liquid or semi-liquid. Figure 1 As shown, the aerosol generating device includes a power supply 1 and an atomizer 2. The power supply 1 is connected to the bottom of the atomizer 2 and is used to supply power to the atomizer 2.

[0036] Figure 2 This is a schematic diagram of the internal structure of an atomizer, such as... Figure 2 As shown, the atomizer 2 includes a liquid storage assembly 21, an atomizing assembly 22, and a nozzle 23. The liquid storage assembly 21 stores the aerosol generation matrix. The atomizing assembly 22 is located in the liquid storage assembly 21 and is used to heat the aerosol generation matrix. The atomizing assembly 22 has an atomization channel 22a. The nozzle 23 is connected to one end of the atomization channel 22a.

[0037] The liquid storage assembly 21 may include a liquid storage chamber housing 211 and a sealing base 212. The sealing base 212 may be fixedly connected to one end of the liquid storage chamber housing 211 or detachably connected to it. The suction nozzle 23 is connected to the other end of the liquid storage chamber housing 211. The liquid storage chamber housing 211 and the sealing base 212 are connected to form a liquid storage chamber 20a, which is used to contain the aerosol generation matrix.

[0038] In some examples, the liquid storage assembly 21 may also include a liquid storage element, such as a liquid storage cotton that has been adsorbed / wetted with an aerosol generation matrix.

[0039] The sealing base 212 can be used to install the electrode block 2121, which is used to electrically connect the atomizing assembly 22 and the power supply 1. The liquid storage assembly 21 can be provided with an air inlet channel 212a. For example, the air inlet channel 212a can be set on the sealing base 212. There can be one or multiple air inlet channels 212a. During suction, outside air can enter the atomizing assembly 22 through the air inlet channel 212a.

[0040] The atomizing assembly 22 is located within the liquid storage chamber housing 211. The atomizing assembly 22 includes an atomizing core cover 221, a liquid guide 222, a heating element 223, and a lead wire 224. The liquid guide 222 and the heating element 223 are located within the atomizing core cover 221. The lead wire 224 is electrically connected to the heating element 223. The lead wire 224 also extends outside the atomizing core cover 221 and connects to the electrode block 2121.

[0041] The atomizing core cover 221 provides space inside the liquid storage tank shell 211 to accommodate the liquid guiding component 222 and the heating component 223. The atomizing core cover 221 can be cylindrical, and its wall can have structures such as holes and slits to allow the aerosol generating matrix in the liquid storage tank shell 211 to enter the atomizing core cover 221 and be absorbed by the liquid guiding component 222. The heating component 223 is used to heat the aerosol generating matrix in the liquid guiding component 222, causing the aerosol generating matrix to vaporize.

[0042] After absorbing the aerosol-generating matrix, the liquid guide 222 becomes moist. During the heating process by the heating element 223, the aerosol-generating matrix in the liquid guide 222 is gradually consumed, and the aerosol-generating matrix in the storage tank 20a is continuously replenished to the liquid guide 222. When the remaining aerosol-generating matrix in the storage tank 20a is insufficient, the aerosol-generating matrix in the liquid guide 222 decreases, and the moisture level decreases. The reduction in the aerosol-generating matrix in the liquid guide 222 leads to a decrease in the mist output of the atomizer 2. Furthermore, as the liquid guide 222 becomes increasingly dry, dry burning may occur, meaning that the liquid guide 222 is continuously heated by the heating element 223 even when there is virtually no aerosol-generating matrix inside, which may cause the liquid guide 222 to burn and ultimately damage the atomizing assembly 22.

[0043] To prevent the atomizing component 22 from burning dry and to avoid damage to the atomizing component 22, this application provides an atomizing component and an atomizer having the atomizing component. Figure 3 This application provides a simplified structural description of a first capacitor. Figure 1 ,like Figure 3 As shown, the atomizing assembly 22 includes a first electrode 31, a liquid guiding member 222, and a second electrode 32. At least a portion of the liquid guiding member 222 is located between the first electrode 31 and the second electrode 32 to separate the first electrode 31 and the second electrode 32.

[0044] At least a portion of the first electrode 31, at least a portion of the liquid guiding member 222, and at least a portion of the second electrode 32 form a first capacitor, the capacitance of which is related to the degree of wettability of the liquid guiding member 222.

[0045] The more aerosol generating matrix stored in the liquid guiding component 222, the higher the wettability of the liquid guiding component 222; the less aerosol generating matrix stored in the liquid guiding component 222, the lower the wettability of the liquid guiding component 222, i.e., the drier it is.

[0046] By setting a first electrode 31 and a second electrode 32 in the atomizing assembly 22, at least a portion of the liquid guiding member 222 is disposed between the first electrode 31 and the second electrode 32, thus separating the first electrode 31 and the second electrode 32. A first capacitor is formed by the first electrode 31, the second electrode 32, and the liquid guiding member 222, with the liquid guiding member 222 acting as the dielectric in the first capacitor. The dielectric constant of the liquid guiding member 222 can affect the capacitance value of the first capacitor. The dielectric constant of the liquid guiding member 222 is affected by the degree of wettability of the liquid guiding member 222, which in turn reflects the remaining amount of aerosol generating matrix in the atomizer 2. Therefore, the capacitance value of the first capacitor can reflect the remaining amount of aerosol generating matrix in the atomizer 2, allowing the user to stop using the atomizing assembly 22 when the remaining amount is low, preventing the atomizing assembly 22 from burning out and avoiding damage to the atomizing assembly 22.

[0047] The capacitance of the first capacitor can be positively correlated with the wettability of the liquid guide 222. Generally, the drier the liquid guide 222, the smaller its dielectric constant, and the smaller the capacitance of the first capacitor formed by the first electrode 31, the liquid guide 222, and the second electrode 32; conversely, the higher the wettability of the liquid guide 222, the larger its dielectric constant, and the larger the capacitance of the first capacitor. There is a corresponding relationship between the capacitance of the first capacitor and the wettability of the liquid guide 222. During the design or manufacture of the atomizer 2, the minimum wettability required for the atomizing component 22 to function properly can be determined through experiments, and the capacitance of the first capacitor at this wettability level can be measured and used as the first preset value. During the use of the aerosol generating device, when the capacitance value of the first capacitor is detected to drop below the first preset value, it indicates that the wettability of the liquid guide 222 has decreased to a level insufficient to maintain the normal operation of the atomizing component 22. The atomizer 2 can be stopped from being used to avoid damage to the atomizing component 22.

[0048] In some examples, the first electrode 31 and the second electrode 32 may be sheet-like, with at least a portion of the liquid guiding member 222 sandwiched between the first electrode 31 and the second electrode 32. The first electrode 31 and the second electrode 32 may be respectively attached to the liquid guiding member 222.

[0049] To facilitate the detection of the capacitance value of the first capacitor, the atomizing component 22 may also include multiple leads 224, one of which can be electrically connected to the first electrode 31, and another lead 224 can be connected to the second electrode 32. The leads 224 are used for electrical connection to the power supply 1, so that the control component 11 in the power supply 1 can control the atomizing component 22 based on the capacitance value of the first capacitor. For details, please refer to the subsequent description of the power supply 1.

[0050] Lead 224 can be made of one of the following: nickel, silver, nickel alloy, silver alloy, nickel-plated copper composite material, or copper-plated nickel composite material.

[0051] The lead wire 224 made of the above-mentioned materials has good electrical conductivity, suitable for current transmission requirements. It also has a certain degree of corrosion resistance, able to resist oxidation and chemical corrosion to a certain extent, maintaining the stable performance of the lead wire 224. Furthermore, it has good mechanical properties, able to withstand a certain degree of tension and bending, making it suitable for applications requiring high mechanical strength.

[0052] For example, the lead 224 can be welded to the first electrode 31 or the second electrode 32, for example, by resistance welding, laser welding, arc welding, friction welding, electromagnetic welding, cold welding, electron beam welding, brazing, tin soldering, spot welding and other methods.

[0053] Figure 4 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application. Figure 1 ,like Figure 4 As shown, the atomizing component 22 includes a heating element 223 and an atomizing core cover 221. The liquid guiding component 222 includes a first liquid guiding component 2221, which is sleeved on the heating element 223, and the atomizing core cover 221 is sleeved on the first liquid guiding component 2221.

[0054] The first liquid guiding component 2221 can be interference-fitted with the heating component 223; the atomizing core outer cover 221 can be interference-fitted with the first liquid guiding component 2221.

[0055] For example, the first liquid guiding element 2221 may be formed of one or two of the following: multilayer nonwoven fabric, PA / PET integrated composite cotton, and cotton.

[0056] Heating element 223 may include one or more heating grids, for example, Figure 4 As shown, the heating element 223 includes one heating mesh. In other possible implementations, the heating element 223 may also include two or more heating meshes arranged axially spaced along the first liquid guide 2221.

[0057] The material and structure of the heating element 223 are not limited, as long as it can generate heat. For example, the heating element 223 may include at least one of heating mesh, heating film, heating wire, and heating plate.

[0058] For example, the heating element 223 may be formed of at least one material selected from stainless steel, nickel-chromium-aluminum alloy, nickel 50, titanium, and titanium alloy.

[0059] The heating element 223, made of metal, can withstand high temperatures, which helps to extend the service life of the atomizing component 22.

[0060] As an example, the heating element 223 can be made of a material with TCR (Temperature Coefficient of Resistance) properties. For example, the heating element 223 can be made of a PTC (Positive Temperature Coefficient) material.

[0061] During the operation of the atomizing component 22, the temperature of the heating element 223 can be determined based on its resistance and the temperature coefficient of resistance. Methods for determining temperature based on resistance and the temperature coefficient of resistance can be found in relevant technologies.

[0062] Figure 5 This application provides a simplified structural description of a first capacitor. Figure 2 ,like Figure 5 As shown, at least a portion of the first liquid guiding element 2221 is located between the first electrode 31 and the second electrode 32, and the capacitance value of the first capacitor is related to the degree of wetting of the first liquid guiding element 2221.

[0063] The first electrode 31 can be disposed inside the first liquid guiding member 2221, and the second electrode 32 can be disposed outside the first liquid guiding member 2221, thereby forming a first capacitor.

[0064] A first capacitor is formed by adding a first electrode 31 and a second electrode 32 to the atomizing component 22. The area and setting position of the first electrode 31 and the second electrode 32 are relatively flexible.

[0065] As an example, the first electrode 31 can be attached to the inner wall of the first liquid guide 2221, and the second electrode 32 can be sandwiched between the first liquid guide 2221 and the atomizing core cover 221.

[0066] Space is limited in the atomizing component 22. To save space and further reduce the cost of the atomizing component 22, in some examples, a portion of the structure in the atomizing component 22 can be reused as the first electrode 31 or the second electrode 32. For example, one of the heating element 223 and the atomizing core cover 221 can be reused as the first electrode 31, and the other can be reused as the second electrode 32.

[0067] like Figure 4 As shown, in the atomizing assembly 22, at least a portion of the heating element 223 constitutes the first electrode 31. That is, at least a portion of the heating element 223 is reused as the first electrode 31, the heating element 223 and the first electrode 31 are the same structural component, and the heating element 223 is used for both heating and as an electrode of the first capacitor.

[0068] The heating element 223 is located inside the first liquid guiding element 2221 and is also a conductive structure. The heating element 223 is reused as the first electrode 31, so there is no need to set up other structures as the first electrode 31, which simplifies the structure and helps to reduce the manufacturing cost of the atomizing component 22.

[0069] Reusing the heating element 223 as the first electrode 31 can also reduce the number of leads 224, further reducing costs. The leads 224 connected to the heating element 223 are used not only to detect the capacitance value of the first capacitor, but also to supply power to the heating element 223, causing it to heat up.

[0070] In this example, the heating element 223 can be cylindrical. The heating element 223 is wound into a cylindrical shape and disposed inside the first liquid guiding element 2221. The heating element 223 is reused as the first electrode 31, so that the second electrode 32 can be disposed at any position in the circumferential direction of the first liquid guiding element 2221 and can be opposite to at least a part of the first electrode 31, thereby forming a first capacitor.

[0071] To further reduce costs, such as Figure 4 As shown, at least a portion of the atomizer core cover 221 can constitute the second electrode 32. That is, at least a portion of the atomizer core cover 221 is reused as the second electrode 32. The atomizer core cover 221 and the second electrode 32 are the same structural component. The atomizer core cover 221 is used to support the atomizing assembly 22 and also serves as the electrode of the first capacitor, thus eliminating the need to separately provide the second electrode 32.

[0072] The atomizing core cover 221 is fitted over the first liquid guiding component 2221. In terms of relative position, the heating element 223 and the atomizing core cover 221 are located on opposite sides of the first liquid guiding component 2221. By reusing the heating element 223 as the first electrode 31 and the atomizing core cover 221 as the second electrode 32, there is no need to add additional structures as the first electrode 31 and the second electrode 32, which simplifies the structure and helps to reduce the manufacturing cost of the atomizing assembly 22.

[0073] The heating element 223 being reused as the first electrode 31 and the atomizing core cover 221 being reused as the second electrode 32 can be independent of each other. That is, when the heating element 223 is reused as the first electrode 31, the second electrode 32 can still be set separately and sandwiched between the first liquid guiding element 2221 and the atomizing core cover 221. When the atomizing core cover 221 is reused as the second electrode 32, the first electrode 31 can also be set separately inside the first liquid guiding element 2221, without using the heating element 223 as the first electrode 31.

[0074] In some examples, the atomizer core cover 221 can be a conductive component. For instance, the atomizer core cover 221 can be a metal structural component, meaning it can be made of metal materials such as aluminum, aluminum alloy, or stainless steel. This eliminates the need for special treatment of the atomizer core cover 221, and the entire cover or any part thereof can be reused as the second electrode 32. Furthermore, metal structural components have good high-temperature resistance, allowing them to withstand the high temperatures generated by the heating element 223 during the operation of the atomization assembly 22.

[0075] Figure 6 This is a schematic diagram of the structure of an atomizing core cover provided in an embodiment of this application. Figure 1 In order to reduce the weight of the atomizing component 22 and lower the cost, such as Figure 6 As shown, in some examples, the atomizing core cover 221 may include a second insulating body 2210 and a second conductive layer 2211 formed on the surface of the second insulating body 2210, at least a portion of the second conductive layer 2211 constituting the second electrode 32.

[0076] For example, the second insulating body 2210 can be a plastic structural component, a ceramic structural component, or a glass structural component, that is, the second insulating body 2210 can be made of plastic, ceramic or glass.

[0077] By providing a second conductive layer 2211 on the surface of the second insulating body 2210, the second conductive layer 2211 being made of a conductive material can be reused as the second electrode 32.

[0078] For example, the second conductive layer 2211 may be a metal plating layer. The material of the second conductive layer 2211 may include at least one of copper, aluminum, zinc, nickel, chromium, and tin.

[0079] The second conductive layer 2211 can cover the entire surface of the second insulating body 2210, or it can only cover a portion of the surface of the second insulating body 2210. Reusing the second conductive layer 2211 as the second electrode 32 allows for flexible setting of the size and position of the second electrode 32.

[0080] The second insulating body 2210 may be tubular, and the second conductive layer 2211 may be disposed on the inner wall of the second insulating body 2210, covering all or part of the inner wall of the second insulating body 2210, or disposed on the outer wall of the second insulating body 2210, covering all or part of the outer wall of the second insulating body 2210.

[0081] The second conductive layer 2211 can be disposed around the second insulating body 2210, that is, the second conductive layer 2211 is annular and disposed along the circumference of the second insulating body 2210. This ensures that no matter how the first electrode 31 is disposed, at least a portion of the second conductive layer 2211 will always be opposite to the first electrode 31, thereby forming the first capacitor.

[0082] As an example, the heating element 223 is reused as the first electrode 31, and the atomizing core cover 221 is reused as the second electrode 32, with the atomizing core cover 221 being a metal structural component; alternatively, the heating element 223 is reused as the first electrode 31, and the second conductive layer 2211 of the atomizing core cover 221 is reused as the second electrode 32, with the second conductive layer 2211 surrounding the second insulating body 2210. This arrangement results in a larger relative area between the first electrode 31 and the second electrode 32. When the wettability of the first liquid guiding element 2221 is the same, a larger relative area between the first electrode 31 and the second electrode 32 results in a larger capacitance value for the first capacitor. The change in capacitance value caused by a change in the wettability of the first liquid guiding element 2221 is also more pronounced, which facilitates a more accurate determination of the wettability of the first liquid guiding element 2221 based on the capacitance value.

[0083] The atomizer core cover 221 is reused as the second electrode 32, and the lead 224 connected to the second electrode 32 can be connected to the atomizer core cover 221. In the example where the atomizer core cover 221 is a conductive component, the lead 224 connected to the second electrode 32 can be soldered at any position on the atomizer core cover 221; in the example where the atomizer core cover 221 includes a second insulating body 2210 and a second conductive layer 2211, the lead 224 connected to the second electrode 32 can be soldered to the second conductive layer 2211.

[0084] The atomizer coil cover 221 has a third end 221a and a fourth end 221b. The third end 221a is used to connect to the mouthpiece 23 of the atomizer 2, and the fourth end 221b is used to install to the sealing base 212. To facilitate the installation of the leads 224, the fourth end 221b of the atomizer coil cover 221 may be provided with a second wiring portion 2212. Multiple leads 224 may include a second lead 2242, which is electrically connected to the second wiring portion 2212.

[0085] The second wiring part 2212 is set at the fourth end 221b of the atomizing core cover 221, and the second lead 2242 does not need to extend into the interior of the atomizing component 22, which facilitates the setting of the second lead 2242.

[0086] The second wiring portion 2212 can be in the form of a sheet, and the second wiring portion 2212 can be provided to protrude from the end face of the fourth end 221b of the atomizing core cover 221, so as to facilitate the soldering of the second lead 2242.

[0087] When the atomizer core cover 221 is a metal part, the second wiring portion 2212 and the atomizer core cover 221 can be an integral structure. When the atomizer core cover 221 includes a second insulating body 2210 and a second conductive layer 2211, the second wiring portion 2212 can also include a conductive plating layer, which is connected to the second conductive layer 2211, so that the second lead 2242 can be electrically connected to the second conductive layer 2211.

[0088] In some examples, the atomizing component 22 may also include an atomizing coil holder 225. Figure 7 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application. Figure 2 ,like Figure 7 As shown, the atomizing assembly 22 includes a heating element 223, an atomizing core support 225, and an atomizing core cover 221. The liquid guiding component 222 includes a first liquid guiding component 2221 and a second liquid guiding component 2222. The axial length of the second liquid guiding component 2222 can be greater than the axial length of the first liquid guiding component 2221. The atomizing core support 225 has a first end 225a and a second end 225b, which are opposite to each other. The first end 225a is used to connect to the mouthpiece 23 of the atomizer 2, and the second end 225b is used to install to the sealing base 212.

[0089] Figure 8 This is a schematic diagram of the internal structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 8 As shown, the heating element 223, the first liquid guiding element 2221, the atomizing core support 225, the second liquid guiding element 2222, and the atomizing core cover 221 are sequentially fitted from the inside to the outside. That is, the first liquid guiding element 2221 is fitted outside the heating element 223, the atomizing core support 225 is fitted outside the first liquid guiding element 2221, the second liquid guiding element 2222 is fitted outside the atomizing core support 225, and the atomizing core cover 221 is fitted outside the second liquid guiding element 2222.

[0090] The first liquid guiding component 2221 can be interference-fitted with the heating component 223; the atomizing core support 225 can be interference-fitted with the first liquid guiding component 2221; the second liquid guiding component 2222 can be interference-fitted with the atomizing core support 225; and the atomizing core outer cover 221 can be interference-fitted with the second liquid guiding component 2222.

[0091] The atomizing core support 225 can also be tubular, and the tube wall of the atomizing core support 225 can have structures such as holes and slits so that the aerosol generating matrix in the second liquid guiding element 2222 can enter the atomizing core support 225 and be absorbed by the first liquid guiding element 2221.

[0092] In some examples, the second liquid guiding element 2222 can be formed from one or two of the following: multilayer nonwoven fabric, PA / PET integrated composite cotton, and cotton.

[0093] The material of the second liquid guiding component 2222 can be the same as or different from that of the first liquid guiding component 2221, and the density of the second liquid guiding component 2222 can be less than that of the first liquid guiding component 2221. Both the first liquid guiding component 2221 and the second liquid guiding component 2222 have pores, and the porosity of the first liquid guiding component 2221 can be less than that of the second liquid guiding component 2222, so as to promote the flow of the aerosol generation matrix in the second liquid guiding component 2222 to the first liquid guiding component 2221.

[0094] At least a portion of at least one of the first liquid guiding element 2221 and the second liquid guiding element 2222 may be located between the first electrode 31 and the second electrode 32, thereby forming a first capacitor. For example, Figure 9 This application provides a simplified structural description of a first capacitor. Figure 4 ,like Figure 9 As shown, the first electrode 31 can be located inside the first liquid guiding member 2221, and the second electrode 32 can be located between the first liquid guiding member 2221 and the second liquid guiding member 2222. Figure 10 This application provides a simplified structural description of a first capacitor. Figure 5 ,like Figure 10 As shown, the first electrode 31 can be located inside the first liquid guiding member 2221, and the second electrode 32 can be located outside the second liquid guiding member 2222. Figure 11 This application provides a simplified structural description of a first capacitor. Figure 6 ,like Figure 11 As shown, the first electrode 31 is located between the first liquid guiding element 2221 and the second liquid guiding element 2222, and the second electrode 32 is located outside the second liquid guiding element 2222.

[0095] for Figure 7 The atomizing component 22 shown can also reuse a portion of its structure as the first electrode 31 or the second electrode 32. For example, one of the heating element 223, the atomizing core support 225, and the atomizing core cover 221 can be reused as the first electrode 31, and the other of them can be reused as the second electrode 32.

[0096] For example, at least a portion of the heating element 223 may constitute the first electrode 31. That is, at least a portion of the heating element 223 is reused as the first electrode 31.

[0097] The heating element 223 is located inside the first liquid guiding element 2221 and is also a conductive structure. When the first electrode 31 is located inside the first liquid guiding element 2221, the heating element 223 is reused as the first electrode 31. This eliminates the need to set up other structures as the first electrode 31, simplifies the structure, and helps reduce the manufacturing cost of the atomizing component 22.

[0098] In this example, reusing the heating element 223 as the first electrode 31 also reduces the number of leads 224, further lowering costs. The leads 224 connected to the heating element 223 are used not only to detect the capacitance value of the first capacitor but also to supply power to the heating element 223, causing it to heat up.

[0099] correspond Figure 7 The atomizing component 22 shown can also have at least a portion of the atomizing core cover 221 used as the second electrode 32. That is, at least a portion of the atomizing core cover 221 is reused as the second electrode 32.

[0100] The atomizing core cover 221 is fitted over the second liquid guiding component 2222. In terms of relative position, the heating element 223 and the atomizing core cover 221 are located on opposite sides of the liquid guiding component 2222. When the first electrode 31 is located inside the first liquid guiding component 2221 and the second electrode 32 is located outside the second liquid guiding component 2222, the heating element 223 is reused as the first electrode 31, and the atomizing core cover 221 is reused as the second electrode 32. The heating element 223, the first liquid guiding component 2221, the second liquid guiding component 2222, and the atomizing core cover 221 together form a first capacitor. The degree of wettability of the first liquid guiding component 2221 and the second liquid guiding component 2222 jointly affect the capacitance value of the first capacitor. This eliminates the need for additional structures as the first electrode 31 and the second electrode 32, simplifying the structure and reducing the manufacturing cost of the atomizing assembly 22.

[0101] In some examples, the atomizer coil cover 221 may be a conductive element. In other examples, the atomizer coil cover 221 may include a second insulating body 2210 and a second conductive layer 2211 formed on the surface of the second insulating body 2210, at least a portion of the second conductive layer 2211 constituting the second electrode 32. The structure of the atomizer coil cover 221 can be referred to the foregoing examples, and will not be described in detail here.

[0102] like Figure 7 As shown, the atomizing assembly 22 may further include a support ring 226, which may be disposed in the second end 225b of the atomizing coil holder 225. The support ring 226 can be used to support the atomizing coil holder 225 and prevent the atomizing coil holder 225 from shrinking or deforming. The lead wire 224 connected to the heating element 223 can extend from between the support ring 226 and the atomizing coil holder 225.

[0103] The atomizing assembly 22 may further include a first seal 2271 and a second seal 2272, both of which may be annular. The first seal 2271 may be disposed at the fourth end 221b of the atomizing core cover 221, and the first seal 2271 may be in a sealing engagement with the fourth end 221b of the atomizing core cover 221 and the second end 225b of the atomizing core support 225. At least a portion of the lead wire 224 may pass through the first seal 2271. The second seal 2272 may be disposed at the third end 221a of the atomizing core cover 221, and the second seal 2272 may be in a sealing engagement with the third end 221a of the atomizing core cover 221 and the first end 225a of the atomizing core support 225.

[0104] For example, the first seal 2271 and the second seal 2272 may be rubber or silicone parts.

[0105] Figure 12 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application. Figure 3 ,like Figure 12 As shown, in some examples, at least a portion of the atomizer core holder 225 can constitute the second electrode 32. That is, at least a portion of the atomizer core holder 225 is reused as the second electrode 32, the atomizer core holder 225 and the second electrode 32 are the same structural component, and the atomizer core holder 225 is used to support the atomization assembly 22 and also serves as an electrode of the first capacitor.

[0106] The atomizing core support 225 is sleeved outside the first liquid guiding component 2221. In terms of relative position, the heating element 223 and the atomizing core support 225 are located on opposite sides of the first liquid guiding component 2221. When the first electrode 31 is located inside the first liquid guiding component 2221, and the second electrode 32 is located between the first liquid guiding component 2221 and the second liquid guiding component 2222, the heating element 223 is reused as the first electrode 31, and the atomizing core support 225 is reused as the second electrode 32. The heating element 223, the first liquid guiding component 2221, and the atomizing core support 225 together form a first capacitor. The degree of wettability of the first liquid guiding component 2221 affects the capacitance value of the first capacitor. This eliminates the need for additional structures as the first electrode 31 and the second electrode 32, simplifying the structure and reducing the manufacturing cost of the atomizing assembly 22.

[0107] In some examples, the atomizer core holder 225 can be a conductive component. For instance, the atomizer core holder 225 can be a metal structural component, meaning it can be made of metal materials such as aluminum, aluminum alloy, or stainless steel. This eliminates the need for special treatment of the atomizer core holder 225, and the entire atomizer core holder 225 or any part thereof can be reused as the second electrode 32. Furthermore, metal structural components have good high-temperature resistance, allowing them to withstand the high temperatures generated by the heating element 223 during the operation of the atomization assembly 22.

[0108] Figure 13 This is a schematic diagram of the structure of an atomizing core cover provided in an embodiment of this application. Figure 2 In order to reduce the weight of the atomizing component 22 and lower the cost, such as Figure 13 As shown, in some examples, the atomizing core holder 225 may include a first insulating body 2250 and a first conductive layer 2251 formed on the surface of the first insulating body 2250, at least a portion of the first conductive layer 2251 constituting the second electrode 32.

[0109] For example, the first insulating body 2250 can be a plastic structural component, a ceramic structural component, or a glass structural component, that is, the first insulating body 2250 can be made of plastic, ceramic or glass.

[0110] By providing a first conductive layer 2251 on the surface of the first insulating body 2250, the first conductive layer 2251 being made of a conductive material can be reused as the second electrode 32.

[0111] For example, the first conductive layer 2251 may be a metal plating layer. The material of the first conductive layer 2251 may include at least one of copper, aluminum, zinc, nickel, chromium, and tin.

[0112] The first conductive layer 2251 can cover the entire surface of the first insulating body 2250, or it can only cover a portion of the surface of the first insulating body 2250. Reusing the first conductive layer 2251 as the second electrode 32 allows for flexible setting of the size and position of the second electrode 32.

[0113] The first insulating body 2250 may be tubular, and the first conductive layer 2251 may be disposed on the inner wall of the first insulating body 2250, covering all or part of the inner wall of the first insulating body 2250, or disposed on the outer wall of the first insulating body 2250, covering all or part of the outer wall of the first insulating body 2250.

[0114] The first conductive layer 2251 can be disposed around the first insulating body 2250, that is, the first conductive layer 2251 is annular and disposed along the circumference of the first insulating body 2250. This ensures that no matter how the first electrode 31 is disposed, at least a portion of the first conductive layer 2251 will always be opposite the first electrode 31, thereby forming a first capacitor.

[0115] As an example, the heating element 223 is reused as the first electrode 31, and the atomizing core support 225 is reused as the second electrode 32, with the atomizing core support 225 being a metal structure; alternatively, the heating element 223 is reused as the first electrode 31, and the first conductive layer 2251 of the atomizing core support 225 is reused as the second electrode 32, with the first conductive layer 2251 surrounding the first insulating body 2250. This arrangement results in a larger relative area between the first electrode 31 and the second electrode 32. When the wettability of the first liquid guiding element 2221 is the same, a larger relative area between the first electrode 31 and the second electrode 32 results in a larger capacitance value for the first capacitor. The change in capacitance value caused by a change in the wettability of the first liquid guiding element 2221 is also more significant, which helps to more accurately determine the wettability of the first liquid guiding element 2221 based on the capacitance value.

[0116] The atomizer core holder 225 is reused as the second electrode 32, and the lead 224 connected to the second electrode 32 can be connected to the atomizer core holder 225. In the example where the atomizer core holder 225 is a conductive element, the lead 224 connected to the second electrode 32 can be soldered to any position on the atomizer core holder 225; in the example where the atomizer core holder 225 includes a first insulating body 2250 and a first conductive layer 2251, the lead 224 connected to the second electrode 32 can be soldered to the first conductive layer 2251.

[0117] To facilitate the installation of the lead wire 224, the second end 225b of the atomizer core holder 225 may be provided with a first connector 2252. The multiple leads 224 may include a first lead wire 2241, which is electrically connected to the first connector 2252.

[0118] The first wiring part 2252 is set at the second end 225b of the atomizing core bracket 225, and the first lead 2241 does not need to extend into the interior of the atomizing component 22, which facilitates the setting of the first lead 2241.

[0119] The first wiring portion 2252 can be in the form of a sheet, and the first wiring portion 2252 can be provided to protrude from the end face of the second end 225b of the atomizing core bracket 225, so as to facilitate the soldering of the first lead 2241.

[0120] When the atomizer core holder 225 is a metal part, the first wiring portion 2252 and the atomizer core holder 225 can be an integral structure. When the atomizer core holder 225 includes a first insulating body 2250 and a first conductive layer 2251, the first wiring portion 2252 may also include a conductive plating layer, which is connected to the first conductive layer 2251, so that the first lead 2241 can be electrically connected to the first conductive layer 2251.

[0121] In Figure 11In the example shown, at least a portion of the second liquid guiding element 2222 is located between the first electrode 31 and the second electrode 32. The capacitance value of the first capacitor is related to the degree of wetting of the second liquid guiding element 2222, so that the degree of wetting of the second liquid guiding element 2222 can be reflected by the capacitance value of the first capacitor.

[0122] Figure 14 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application. Figure 4 ,like Figure 14 As shown, in some examples, at least a portion of the atomizer core holder 225 can constitute the first electrode 31, that is, the atomizer core holder 225 can be reused as the first electrode 31. The atomizer core holder 225 and the first electrode 31 are the same structural component. The atomizer core holder 225 is used to support the atomizing assembly 22 and also serves as the electrode of the first capacitor.

[0123] When the atomizing core support 225 is located between the first liquid guiding component 2221 and the second liquid guiding component 2222, and the first electrode 31 is located between the first liquid guiding component 2221 and the second liquid guiding component 2222, the atomizing core support 225 is reused as the first electrode 31. This eliminates the need for additional structures as the first electrode 31, simplifies the structure, and helps reduce the manufacturing cost of the atomizing component 22.

[0124] At least a portion of the atomizer core cover 221 can constitute the second electrode 32. That is, at least a portion of the atomizer core cover 221 is reused as the second electrode 32.

[0125] The second liquid guiding component 2222 is sleeved outside the atomizing core support 225. In terms of relative position, the atomizing core support 225 and the atomizing core cover 221 are located on both sides of the second liquid guiding component 2222. The atomizing core support 225 is reused as the first electrode 31, and the atomizing core cover 221 is reused as the second electrode 32. This eliminates the need for additional structures as the first electrode 31 and the second electrode 32, simplifying the structure and reducing the manufacturing cost of the atomizing assembly 22.

[0126] To separately reflect the wettability of the first liquid guide 2221 and the second liquid guide 2222, thereby facilitating safer use of the aerosol generating device and preventing dry burning, in some examples, the atomizing assembly 22 may also include a third electrode 33 to form a second capacitor.

[0127] Figure 15 This is a simplified structural diagram of a first capacitor and a second capacitor provided in an embodiment of this application, as shown below. Figure 15As shown, at least a portion of the second liquid guiding element 2222 can be located between the first electrode 31 and the second electrode 32, and at least a portion of the first liquid guiding element 2221 can be located between the third electrode 33 and the first electrode 31. That is, at least a portion of the first electrode 31, at least a portion of the second liquid guiding element 2222, and at least a portion of the second electrode 32 form a first capacitor, the capacitance of which is related to the degree of wetting of the second liquid guiding element 2222; at least a portion of the third electrode 33, at least a portion of the first liquid guiding element 2221, and at least a portion of the first electrode 31 form a second capacitor, the capacitance of which is related to the degree of wetting of the first liquid guiding element 2221. Therefore, the degree of wetting of the second liquid guiding element 2222 can be reflected by the capacitance of the first capacitor, and the degree of wetting of the first liquid guiding element 2221 can be reflected by the capacitance of the second capacitor.

[0128] In some examples, a portion of the structure in the atomizing component 22 can be reused as the first electrode 31, the second electrode 32, or the third electrode 33. For example, the atomizing core support 225 and the atomizing core cover 221 can be reused as the first electrode 31 and the second electrode 32, respectively, and the heating element 223 can be reused as the third electrode 33.

[0129] Figure 16 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application. Figure 5 ,like Figure 16 As shown, at least a portion of the heating element 223 constitutes the third electrode 33, meaning the heating element 223 is reused as the third electrode 33. At least a portion of the third electrode 33, at least a portion of the first liquid guiding element 2221, and at least a portion of the first electrode 31 form a second capacitor, the capacitance of which is related to the degree of wettability of the first liquid guiding element 2221. The heating element 223 and the third electrode 33 are the same structural component; the heating element 223 is used for both heating and as an electrode of the second capacitor.

[0130] The heating element 223 is located inside the first liquid guiding element 2221 and is also a conductive structure. The heating element 223 is reused as the third electrode 33, so there is no need to set up other structures as the third electrode 33, which simplifies the structure and helps to reduce the manufacturing cost of the atomizing component 22.

[0131] Reusing the heating element 223 as the third electrode 33 can also reduce the number of leads 224, further reducing costs. The leads 224 connected to the heating element 223 are used not only to detect the capacitance value of the second capacitor, but also to supply power to the heating element 223, causing it to heat up.

[0132] like Figure 16As shown, at least a portion of the atomizer core support 225 can constitute the first electrode 31, meaning the atomizer core support 225 can be reused as the first electrode 31. The atomizer core support 225 and the first electrode 31 are the same structural component. The atomizer core support 225 serves both to support the atomizing assembly 22 and as an electrode of the first capacitor and the second capacitor. At least a portion of the atomizer core cover 221 can constitute the second electrode 32. That is, at least a portion of the atomizer core cover 221 is reused as the second electrode 32. The atomizer core cover 221 and the second electrode 32 are the same structural component. The atomizer core cover 221 serves both to support the atomizing assembly 22 and as an electrode of the first capacitor.

[0133] By reusing the atomizing core support 225 as the first electrode 31, the atomizing core cover 221 as the second electrode 32, and the heating element 223 as the third electrode 33, the first capacitor and the second capacitor can be formed without the need to set up other structures as electrodes, which simplifies the structure and helps to reduce the manufacturing cost of the atomizing component 22.

[0134] The structure of the atomizer core support 225 and the structure of the atomizer core cover 221 can be referred to the aforementioned relevant content, and will not be described in detail here.

[0135] The reuse of any one of the heating element 223, the atomizing core support 225, and the atomizing core cover 221 can be independent of each other. For example, when the heating element 223 is reused as the first electrode 31, the second electrode 32 can still be set independently. It can be sandwiched between the first liquid guide 2221 and the atomizing core support 225, or between the atomizing core support 225 and the second liquid guide 2222, or between the second liquid guide 2222 and the atomizing core cover 221; the atomizing core support 225 can be reused as the first electrode 31. When electrode 31 is used, the second electrode 32 can still be set separately and can be sandwiched between the second liquid guide 2222 and the atomizing core cover 221. The third electrode 33 can also be set separately and can be set inside the first liquid guide 2221. When the atomizing core support 225 is reused as the second electrode 32, the first electrode 31 can still be set separately and can be set inside the first liquid guide 2221. When the atomizing core cover 221 is reused as the second electrode 32, both the first electrode 31 and the second electrode 32 can be set separately.

[0136] This application also provides an atomizer. Figure 17 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application. Figure 1 ,like Figure 17 As shown, the atomizer 2 may include a liquid storage assembly 21 and any of the aforementioned atomizing assemblies 22. The atomizing assembly 22 is disposed in the liquid storage assembly 21. Figure 17 China and Israel Figure 7Taking the atomizing component 22 shown as an example, in other possible implementations, the atomizer 2 may also include the other atomizing components 22 mentioned above.

[0137] As an example, such as Figure 17 As shown, the liquid storage assembly 21 may include a liquid storage tank housing 211 and a sealing base 212. Figure 17 At least a portion of the liquid storage tank housing 211 is omitted. The second end 225b of the atomizer core support 225 and the fourth end 221b of the atomizer core cover 221 can be inserted into the sealing base 212 and sealed with it. The first end 225a of the atomizer core support 225 and the first end 225a of the atomizer core cover 221 can communicate with the mouthpiece 23 from the inside of the liquid storage tank housing 211.

[0138] like Figure 17 As shown, the liquid storage tank housing 211 can also be provided with a liquid injection port 211a, and a sealing plug 2111 is detachably provided in the liquid injection port 211a. When the aerosol generating matrix in the liquid storage tank 20a is insufficient, the user can open the sealing plug 2111 and add aerosol generating matrix into the liquid storage tank 20a through the liquid injection port 211a, so that the capacitance value of the first capacitor increases and the atomizing component 22 returns to a normal working state.

[0139] Figure 18 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application. Figure 2 ,like Figure 18 As shown, lead 224 can pass through sealing base 212 and extend to outside liquid storage tank 20a.

[0140] For example, the sealing base 212 may be provided with multiple slots 212b on the side away from the liquid storage tank 20a, and the lead wire 224 may be bent into the slots 212b.

[0141] In some examples, the atomizer 2 may include electrode blocks 2121 (see reference). Figure 2 The slot 212b can be used to accommodate the aforementioned electrode block 2121. The lead 224 is electrically connected to the electrode block 2121, thereby forming an electrical connection with the power supply 1 through the electrode block 2121.

[0142] In other examples, slot 212b can also be used to accommodate electrical connector 112 of power supply 1 (see related content later), with lead 224 directly connected to electrical connector 112, thus eliminating the need for electrode block 2121.

[0143] By applying the aforementioned liquid storage component 21 to the atomizer 2, the capacitance value of the first capacitor can reflect the wettability of the liquid guide component 222 during the use of the aerosol generating device, thereby allowing the user to stop using the device when the aerosol generating matrix in the liquid storage component 21 is insufficient, thus avoiding the atomizing component 22 from burning dry.

[0144] Figure 19 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 19 As shown, the aerosol generating device includes a power source 1 and any of the aforementioned atomizers 2. The power source 1 supplies power to the atomizing assembly 22.

[0145] Figure 20 This is a schematic diagram of a power supply structure provided in an embodiment of this application, such as... Figure 20 As shown, the power supply 1 may include a control component 11. The control component 11 is electrically connected to the first electrode 31 and the second electrode 32. When the capacitance value of the first capacitor is lower than a first preset value, the control component 11 is used to control the power supply 1 to stop supplying power to the atomizing component 22.

[0146] The step of stopping power supply to the atomizing component 22 may include: if the atomizing component 22 is in a powered state, stopping the power supply to the atomizing component 22 so that the atomizing component 22 stops working; if the atomizing component 22 is in a powered-off state, keeping the atomizing component 22 in a powered-off state at least until the capacitance value of the first capacitor becomes greater than the first preset value.

[0147] By controlling the power supply 1 to stop supplying power to the atomizing component 22 through the control component 11, the atomizing component 22 can be prevented from burning dry.

[0148] For the atomizing component 22, which also includes a third electrode 33, the control component 11 can also be electrically connected to the third electrode 33. The control component 11 is also used to control the power supply 1 to stop supplying power to the atomizing component 22 when the capacitance value of the second capacitor is lower than the second preset value.

[0149] Both the first preset value and the second preset value can be determined experimentally. For example, when the degree of wetness of the first liquid guide 2221 is at the minimum degree of wetness required for the atomizing component 22 to work normally, the capacitance value of the first capacitor (the first preset value can be greater than or equal to this capacitance value) and the capacitance value of the second capacitor (the second preset value can be greater than or equal to this capacitance value) when the degree of wetness of the second liquid guide 2222 is at the minimum degree of wetness required for the atomizing component 22 to work normally.

[0150] like Figure 20As shown, the control component 11 may include a circuit board 111 and multiple electrical connectors 112. The multiple electrical connectors 112 are used to electrically connect to the atomizer 2 to supply power to the atomizer 2 or control the operation of the atomizer 2. The electrical connectors 112 can be connected to the aforementioned lead 224 to achieve electrical connection with the atomizer 2.

[0151] The plurality of electrical connectors 112 may include a first electrical connector 1121 and a second electrical connector 1122. One end of the first electrical connector 1121 is connected to the circuit board 111, and the other end of the first electrical connector 1121 is electrically connected to the first electrode 31; one end of the second electrical connector 1122 is connected to the circuit board 111, and the other end of the second electrical connector 1122 is electrically connected to the second electrode 32.

[0152] In this example, the heating element 223 is reused as the first electrode 31, and the plurality of electrical connectors 112 may also include a third electrical connector 1123. The third electrical connector 1123 can be electrically connected to the heating element 223, so that power can be supplied to the heating element 223 through the first electrical connector 1121 and the third electrical connector 1123, causing the heating element 223 to heat up.

[0153] The heating element 223 can be electrically connected to two electrical connectors 112 to form a circuit to supply power to the heating element 223.

[0154] Power supply 1 and atomizer 2 are usually connected by electrical connector 112 for power supply. In this embodiment, it is only necessary to increase the number of electrical connectors 112 and set the electrical connectors 112 to form an electrical connection with the first capacitor, so that it can both supply power to atomizer 2 and facilitate the detection of the capacitance value of the first capacitor.

[0155] In other examples, a second capacitor may also be formed in the atomizing component 22, and the plurality of electrical connectors 112 may further include a fourth electrical connector that forms an electrical connection with the third electrode 33, thereby facilitating the detection of the capacitance value of the second capacitor.

[0156] For example, the electrical connector 112 may be a conductive post. (Refer to...) Figure 18 As shown, the sealing base 212 can be provided with multiple slots 212b on the side away from the liquid storage tank 20a. Multiple electrical connectors 112 can be inserted into the multiple slots 212b respectively. The lead wire 224 can be clamped between the electrical connector 112 and the side wall of the slot 212b, and contact the electrical connector 112 to form an electrical connection.

[0157] In some other possible implementations, the electrical connector 112 may also be soldered to the lead 224.

[0158] like Figure 20As shown, the power supply 1 may also include a power supply bracket 12, a circuit board 111 mounted on the power supply bracket 12, and an electrical connector 112 inserted through the power supply bracket 12.

[0159] The power supply bracket 12 serves to support and protect the circuit board 111 from the atomizer 2. The electrical connector 112 passes through the power supply bracket 12 and is electrically connected to the atomizer 2. In the event of leakage from the atomizer 2, this prevents the leaked liquid from flowing onto the circuit board 111 and causing damage to it.

[0160] The power supply 1 may also include a battery 13, which may be located on the side of the power supply bracket 12 away from the atomizer 2. The battery 13 is electrically connected to the circuit board 111.

[0161] For example, battery 13 may include any one of lithium-ion battery, nickel metal hydride battery, nickel-cadmium battery or lithium-based battery, and lithium-based battery may include lithium cobalt battery, lithium iron phosphate battery, lithium titanate battery or lithium polymer battery.

[0162] The power supply bracket 12 may also be equipped with a sensing airway 12a, and the circuit board 111 may also be equipped with an airflow sensor 1111. One end of the sensing airway 12a is connected to the airflow sensor 1111. When the power supply 1 is connected to the atomizer 2, the other end of the airflow sensor 1111 is connected to the atomizer 2, for example, it can be connected to the fourth end 221b of the atomizer core cover 221, and connected to the atomization channel 22a, so that the airflow sensor 1111 can detect the air pressure in the atomization assembly 22. When the user uses the aerosol generating device, the air pressure in the sensing airway 12a changes, thereby triggering the airflow sensor 1111.

[0163] In related technologies, when a user inhales while using an aerosol generating device, the air pressure within the sensing airway 12a changes, triggering the airflow sensor 1111. This energizes the atomizing component 22, heating the aerosol generating matrix. When the user stops inhaling, the atomizing component 22 is de-energized, ceasing heating of the aerosol generating matrix.

[0164] If the airflow sensor 1111 is triggered when the aerosol generation matrix in the liquid guide 222 is insufficient, causing the atomizing component 22 to be energized, it will lead to a reduction in the amount of mist produced or even dry burning. In this embodiment, since the control component 11 controls the power supply 1 to stop supplying power to the atomizing component 22 when the capacitance value of the first capacitor is lower than the first preset value, the atomizing component 22 remains in a de-energized state. Even if the user inhales and triggers the airflow sensor 1111 at this time, the atomizing component 22 will still be in a de-energized state and will not be heated, thus preventing dry burning.

[0165] To facilitate reminders to users to replenish the aerosol generation matrix, the power supply 1 may also include an alarm device 1112, which is connected to the control component 11. The alarm device 1112 is used to issue an alarm when the capacitance value of the first capacitor is lower than a first preset value.

[0166] For example, the alarm device 1112 may include at least one of an indicator light, a speaker, and a vibration motor. The alarm may include at least one of a light signal, a sound signal, and vibration. For example, the indicator light may flash when the capacitance value of the first capacitor is lower than a first preset value; the speaker may emit a warning sound when the capacitance value of the first capacitor is lower than the first preset value; and the vibration motor may vibrate when the capacitance value of the first capacitor is lower than the first preset value.

[0167] As an example, the alarm device 1112 may include a buzzer that is small in size and can emit a loud sound to provide an alert.

[0168] By setting the alarm device 1112 to issue an alarm when the capacitance value of the first capacitor is lower than the first preset value, the user is promptly reminded to replenish the aerosol generation matrix, which facilitates user use.

[0169] For the atomizing assembly 22, which also includes a third electrode 33, the alarm device 1112 can also be used to issue an alarm when the capacitance value of the second capacitor is lower than a second preset value.

[0170] The control component 11 may also include one or more controllers for controlling the operation of the atomizing component 22. The controllers may be mounted on the circuit board 111.

[0171] For example, the controller may include at least one of the following: MCU (Micro Controller Unit), CPU (Central Processing Unit), FPGA (Field Programmable Gate Array), or other programmable logic devices, discrete gate or transistor logic devices, and discrete hardware components.

[0172] Taking the controller, including the MCU, as an example, during the operation of the aerosol generating device, the MCU's ADC (Analog to Digital Converter) function can be used to sample data in real time. The sampled data may include, for example, the capacitance value of the first capacitor, the capacitance value of the second capacitor, the voltage value across the heating element 223, the resistance value of the heating element 223, etc. When the capacitance value of the first capacitor is lower than the first preset value or the capacitance value of the second capacitor is lower than the second preset value, the controller stops supplying power to the heating element 223.

[0173] The controller can be used to control the heating element 223 to heat at the desired temperature. The controller can determine the temperature of the heating element 223 based on its resistance value, thereby controlling the heating power. For example, the controller can use a proportional... integral Differential (Proportional) Integral Derivative (PID) control is used to regulate the temperature and ensure that the temperature of the heating element 223 is stable at the required temperature.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
