[0002] Common aerosol generating devices include an atomizer and a power supply unit, with the atomizer connected to the power supply unit. During operation, the power supply unit supplies power to the atomizer.

[0003] Atomizers consist of a reservoir and an atomizing component, with the atomizing component housed within the reservoir. The reservoir stores the aerosol-generating matrix. Some atomizers have an inlet on the reservoir, allowing the addition of aerosol-generating matrix when the remaining amount in the reservoir is insufficient. However, the process of adding aerosol matrix is ​​often affected by the internal air pressure of the reservoir, making the addition process somewhat difficult. Summary of the Invention

[0004] This application provides an atomizing component, an atomizer, and an aerosol generating device to facilitate the addition of an aerosol matrix. The technical solution is as follows:

[0005] In a first aspect, embodiments of this application provide an atomizing assembly, the atomizing assembly including an atomizing core cover and an atomizing core support, the atomizing core cover having a cavity, the cavity having an opposite air inlet port and an exhaust port, the exhaust port being used to connect to the mouthpiece of an atomizer, and at least a portion of the atomizing core support being disposed in the atomizing core cover and spaced apart from the exhaust port; The atomizing core cover has a first opening on its side wall, and an exhaust channel is formed between the atomizing core support and the inner side wall of the atomizing core cover. The exhaust channel connects the first opening and the exhaust port.

[0008] In some examples, the outer flange includes a first outer flange having a first notch, the exhaust passage includes the first notch, and the portion of the lumen located between the first outer flange and the exhaust port communicates with the first gap through the first notch.

[0009] In some examples, the outer flange includes a first outer flange that is clearance-fitted with the inner sidewall of the atomizing core cover, and the exhaust channel also includes a gap between the first outer flange and the inner sidewall of the atomizing core cover.

[0010] In some examples, the outer flange further includes a second outer flange located on the side of the first outer flange near the first opening. The second outer flange is clearance-fitted with the inner wall of the atomizing core cover. The exhaust channel also includes a gap between the second outer flange and the inner wall of the atomizing core cover. Alternatively, the second outer flange is provided with a second notch that penetrates the second outer flange on opposite sides of the vent pipe in the axial direction.

[0011] In some examples, the outer diameter of the vent tube is smaller than the outer diameter of the support body, and the first outer flange, the second outer flange, the inner wall of the atomizing core cover, and the outer wall of the vent tube form a receiving cavity.

[0012] In some examples, the end face of the atomizer core holder facing the air intake port is a concave conical surface.

[0013] In some examples, the atomizing assembly further includes a first liquid guide disposed in the atomizing core support. The first liquid guide is cylindrical and its inner diameter is smaller than the inner diameter of the end face of the atomizing core support facing the air inlet port.

[0016] The beneficial effects of the technical solutions provided in this application include at least the following: By placing at least a portion of the atomizing core support in the cavity of the atomizing core cover, and spaced apart from the exhaust port of the cavity, an exhaust channel is formed between the atomizing core support and the inner wall of the atomizing core cover. The exhaust channel connects the exhaust port and the first opening on the side wall of the atomizing core cover. This allows air inside the atomizer to enter the exhaust channel through the first opening during the process of adding the aerosol generation matrix to the atomizer, and then be discharged into the cavity through the exhaust channel and out from the exhaust port. This makes it easier to add the aerosol matrix to the atomizer. Attached Figure Description

[0026] Figure 1 This 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 component 1 and an atomizer 2. The power supply component 1 is used to supply power to the atomizer 2.

[0027] The atomizer 2 includes a liquid storage assembly 21 and an atomizing assembly. Figure 1 The nozzle 23 is not shown. The reservoir assembly 21 stores the aerosol generating matrix. The atomizing assembly is disposed within the reservoir assembly 21. The nozzle 23 is connected to the outside of the reservoir assembly 21. The reservoir assembly 21 is provided with an injection port 21a, through which the aerosol generating matrix can be replenished after it is depleted. During the replenishment of the aerosol generating matrix into the reservoir assembly 21, poor airflow inside the reservoir assembly 21 can lead to difficulties in adding the aerosol generating matrix.

[0028] To facilitate the addition of an aerosol generation matrix, embodiments of this application provide an atomizing component and an atomizer having the atomizing component. Figure 2 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application, as shown below. Figure 2 As shown, the atomizer 2 includes a liquid storage assembly 21, an atomizing assembly 22, and a mouthpiece 23. The atomizing assembly 22 is disposed inside the liquid storage assembly 21 and is connected to the mouthpiece 23.

[0029] Figure 3This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 3 As shown, the liquid storage assembly 21 may include a liquid storage chamber housing 211, a base 212, and a seal 213. The seal 213 is disposed on the surface of the base 212, and the base 212 may be fixedly connected to the liquid storage chamber housing 211 or detachably connected to it. The liquid storage chamber housing 211 and the base 212 form a liquid storage chamber 200a, which is used to contain the aerosol matrix. The base 212 may be used to mount electrodes, which are used for electrical connection with the power supply assembly 1.

[0030] 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 matrix.

[0031] The liquid storage tank shell 211 is provided with a liquid injection port 21a, and a removable sealing plug 214 is provided in the liquid injection port 21a.

[0032] Figure 4 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 4 As shown, the atomizing component 22 includes an atomizing core cover 221 and an atomizing core support 222. Figure 5 This is a schematic diagram of the internal structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 5 As shown, the atomizer coil cover 221 has a cavity 221a, which has an air inlet port 221b and an exhaust port 221c. The exhaust port 221c is used to connect to the mouthpiece 23 of the atomizer 2. At least a portion of the atomizer coil support 222 is disposed in the atomizer coil cover 221 and is spaced apart from the exhaust port 221c.

[0033] The atomizing core cover 221 has a first opening 221d on its side wall, and an exhaust channel 22a is formed between the atomizing core support 222 and the inner side wall of the atomizing core cover 221. The exhaust channel 22a connects the first opening 221d and the exhaust port 221c.

[0034] By placing at least a portion of the atomizing core support 222 within the cavity 221a of the atomizing core cover 221, and spaced apart from the exhaust port 221c of the cavity 221a, an exhaust channel 22a is formed between the atomizing core support 222 and the inner wall of the atomizing core cover 221. This exhaust channel 22a connects the exhaust port 221c and the first opening 221d on the side wall of the atomizing core cover 221. This allows for the addition of the aerosol generation matrix to the atomizer 2, as per [reference to...]. Figure 5As shown by the arrow, the air inside the atomizer 2 can enter the exhaust channel 22a through the first opening 221d, and then be discharged into the tube 221a through the exhaust channel 22a and discharged from the exhaust port 221c, so that the aerosol matrix can be smoothly added to the atomizer 2, making the addition of the aerosol matrix more convenient.

[0035] In some examples, the atomizer coil holder 222 can be a detachable, separate structure. As one example, such as... Figure 5 As shown, the atomizer coil support 222 may include a support body 2221 and an air vent 2222. At least a portion of the support body 2221 is located in the cavity 221a. A first gap 221e is formed between the support body 2221 and the inner wall of the atomizer coil outer cover 221, and the exhaust channel 22a may include the first gap 221e. During the process of adding the aerosol generation matrix to the atomizer 2, the air inside the atomizer 2 can be discharged to the mouthpiece 23 through the first opening 221d and the first gap 221e.

[0036] Vent pipe 2222 is disposed in cavity 221a and connected to the end of support body 2221 near exhaust port 221c. Vent pipe 2222 has an outer flange on its outer wall, and the first opening 221d is located on the side of the outer flange away from exhaust port 221c.

[0037] The outer flange can cooperate with the inner wall of the atomizing core cover 221 to provide radial support for the atomizing core bracket 222.

[0038] The atomizing assembly 22 also includes a first liquid guiding element 223 and a heating element 224. The atomizing core cover 221 provides space inside the liquid storage tank housing 211 to accommodate the first liquid guiding element 223 and the heating element 224. The atomizing core cover 221 may be cylindrical, and the first opening 221d may include holes, slits, or other structures provided on the tube wall of the atomizing core cover 221 to allow the aerosol matrix in the liquid storage tank housing 211 to enter the atomizing core cover 221.

[0039] For example, the first liquid guiding element 223 may be formed by one or two of the following: multilayer nonwoven fabric, PA / PET integrated composite cotton.

[0040] The first liquid guiding element 223 can be cylindrical and can be disposed within the support body 2221, with an interference fit. The heating element 224 can be disposed within the first liquid guiding element 223. When assembling the atomizing assembly 22, the heating element 224 can be first assembled to the first liquid guiding element 223, and then the first liquid guiding element 223 and the heating element 224 can be installed as a whole into the support body 2221. By configuring the atomizing core support 222 as a detachably connected support body 2221 and air pipe 2222, the first liquid guiding element 223 and the heating element 224 can be installed as a whole into the support body 2221 first, and then the air pipe 2222 can be connected to the support body 2221 for easy assembly.

[0041] The heating element 224 is used to heat the aerosol matrix in the liquid guiding component, causing the aerosol matrix to vaporize. The material and structure of the heating element 224 are not limited, as long as it can perform the heating function. For example, the heating element 224 may include at least one of the following: heating mesh, heating film, heating wire, and heating plate.

[0042] The heating element 224 can be a metal structural component. For example, the heating element 224 can be formed of at least one material selected from stainless steel, nickel-chromium-aluminum alloy, nickel 50, titanium, and titanium alloy.

[0043] The heating element 224, made of metal, can withstand high temperatures, which helps to extend the service life of the atomizing component 22.

[0044] As an example, the heating element 224 can be made of a material with TCR (Temperature Coefficient of Resistance) properties. For example, the heating element 224 can be made of a PTC (Positive Temperature Coefficient) material.

[0045] During the operation of the heating element, the temperature of the heating element 224 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.

[0046] The heating element 224 may be connected to a lead 225, which, by way of example, may be soldered to the heating element 224. The lead 225 is used to connect to an electrode.

[0047] Lead 225 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.

[0048] Lead wire 225 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 lead wire 225. 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.

[0049] The vent tube 2222 can be sleeved with the support body 2221. For example, one end of the vent tube 2222 can be inserted into the support body 2221. In this way, the first liquid guide 223 can be axially limited through the end of the vent tube 2222.

[0050] In some other possible implementations, the atomizer core support 222 can also be an integral structure, with the support body 2221 and the air tube 2222 being a single unit.

[0051] The first opening 221d can be directly opposite the side wall of the support body 2221. A second opening 2221a can be provided on the side wall of the support body 2221, and the first liquid guiding element 223 can block the second opening 2221a inside the support body 2221. During the use of the aerosol generating device, the aerosol generating matrix in the liquid storage component 21 can enter the first liquid guiding element 223 through the first opening 221d and the second opening 2221a, and then form an aerosol under the action of the heating element 224.

[0052] The atomizing component 22 may further include a second liquid guiding element 226, which may be sleeved on the outside of the support body 2221 to block the second opening 2221a. The second liquid guiding element 226 may store a portion of the aerosol generation matrix and allow the aerosol generation matrix to enter the support body 2221 uniformly and slowly and be absorbed by the first liquid guiding element 223.

[0053] For example, the second liquid guiding element 226 may be formed of one or both of the following: multilayer nonwoven fabric, PA / PET integrated composite cotton.

[0054] One or more outer flanges can be provided; multiple outer flanges can better provide radial support. As an example, such as... Figure 5 As shown, the outer flange may include a first outer flange 22221, which has a first notch 221g, and the exhaust passage 22a also includes the first notch 221g. The portion of the lumen 221a located between the first outer flange 22221 and the exhaust port 221c is connected to the first gap 221e through the first notch 221g.

[0055] The arrangement of the first outer flange 22221 affects the airflow from the first gap 221e into the cavity 221a. By setting the first notch 221g on the first outer flange 22221, the airflow can pass through the first notch 221g, while not affecting the radial limitation of the first outer flange 22221 on the atomizing core support 222.

[0056] In some examples, there may be multiple first notches 221g, and the multiple first notches 221g may be distributed at circumferential intervals along the first outer flange 22221.

[0057] Setting multiple first notches 221g distributed circumferentially can reduce the resistance to airflow, making it easier for airflow to pass through the first outer flange 22221, and facilitating the addition of aerosol to generate a matrix.

[0058] The size of the first notch 221g can be set to be small, so that when the aerosol generating matrix reaches the first outer flange 22221, the aerosol generating matrix is ​​not easy to pass through the first notch 221g.

[0059] In some examples, the first outer flange 22221 and the inner wall of the atomizing core cover 221 can be clearance-fitted, and the exhaust channel 22a also includes a gap between the first outer flange 22221 and the inner wall of the atomizing core cover 221. Thus, even if the first notch 221g is not provided on the first outer flange 22221, airflow can still be discharged through the gap between the first outer flange 22221 and the inner wall of the atomizing core cover 221.

[0060] like Figure 5 As shown, the outer flange may further include a second outer flange 22222. The second outer flange 22222 is located on the side of the first outer flange 22221 near the first opening 221d. The second outer flange 22222 has a clearance fit with the inner wall of the atomizing core cover 221. The exhaust channel 22a may further include the gap between the second outer flange 22222 and the inner wall of the atomizing core cover 221.

[0061] The gap between the second outer flange 22222 and the inner wall of the atomizing core cover 221 allows airflow to pass through and reach the first notch 221g, and can also cooperate with the atomizing core cover 221 to achieve radial limiting of the atomizing core support 222.

[0062] In some examples, a second notch may also be provided on the second outer flange 22222, extending through the second outer flange 22222 on both opposite sides of the vent pipe 2222 in the axial direction. The exhaust passage 22a also includes this second notch. The structure of the second notch may be the same as the aforementioned first notch 221g. Providing a second notch on the second outer flange 22222 can also serve as a connection, ensuring that the second outer flange 22222 does not obstruct airflow.

[0063] like Figure 5 As shown, the first outer flange 22221, the second outer flange 22222, the inner wall of the atomizing core cover 221, and the outer wall of the vent pipe 2222 form a receiving cavity 221f, and the exhaust channel 22a also includes the receiving cavity 221f. The outer diameter of the vent pipe 2222 is smaller than the outer diameter of the support body 2221.

[0064] In this embodiment of the application, the outer diameter of the vent pipe 2222 refers to the outer diameter of the portion of the vent pipe 2222 located outside the outer flange. For example, the outer diameter of the vent pipe 2222 can refer to the outer diameter of the portion of the vent pipe 2222 located between the first outer flange 22221 and the second outer flange 22222.

[0065] During the user's suction process, under the negative pressure within the lumen 221a, the aerosol-generating matrix in the liquid storage component 21 can enter the second liquid guide 226 through the first opening 221d, and then flow from the second liquid guide 226 to the first liquid guide 223. Simultaneously, a portion of the aerosol-generating matrix can also flow through the first gap 221e to the receiving cavity 221f. When the user stops suctioning, the aerosol-generating matrix in the receiving cavity 221f can flow back into the first gap 221e, returning to the liquid storage component 21. This reduces the pressure difference between the outside of the second liquid guide 226 and the inside of the first liquid guide 223, balancing some of the negative pressure and preventing excessive pressure difference from causing excessive aerosol-generating matrix to enter the first liquid guide 223 and leak.

[0066] Setting the outer diameter of the vent tube 2222 to be smaller than the outer diameter of the support body 2221 gives the receiving cavity 221f a larger volume, allowing it to hold more aerosol generating matrix and providing a certain buffering effect. The aerosol generating matrix flows along the axial direction of the atomizing core cover 221 within the receiving cavity 221f at a lower speed than it flows along the axial direction of the atomizing core cover 221 within the first gap 221e, making it less likely for the aerosol generating matrix to overflow from the first notch 221g. This also provides a buffering effect during the addition of the aerosol generating matrix, preventing it from overflowing from the first notch 221g due to excessive or rapid addition.

[0067] like Figure 5 As shown, the end face of the atomizer core bracket 222 facing the air inlet port 221b can be a concave conical surface 22223.

[0068] During the use of the aerosol generating device, condensate may be generated in the nozzle 23 and the cavity 221a. When this condensate drips or flows along the inner wall of the cavity 221a, it reaches the end face of the atomizing core support 222 facing the air inlet port 221b. Under the guidance of the conical surface 22223, it can quickly drip into the atomizing core support 222 and be absorbed by the first liquid guiding element 223. This prevents condensate from accumulating on the end face of the atomizing core support 222 facing the air inlet port 221b, reduces the possibility of condensate flowing out of the nozzle 23, and helps improve the user experience.

[0069] In some examples, the inner diameter of the first liquid guide 223 may be smaller than the inner diameter of the end face of the atomizing core support 222 facing the air inlet port 221b.

[0070] By making the inner diameter of the first liquid guide 223 smaller, the condensate dripping from the end face of the atomizing core support 222 toward the air inlet port 221b into the atomizing core support 222 can more easily drip directly onto the first liquid guide 223, making it easier for the condensate to be absorbed by the first liquid guide 223.

[0071] Figure 6 This is an exploded structural diagram of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 6 As shown, the aerosol generating device may include a power supply component 1 and an atomizer 2. The atomizer 2 may be any of the aforementioned atomizers 2.

[0072] In some examples, the power supply component 1 is detachably connected to the atomizer 2. Because the power supply component 1 is detachably connected to the atomizer 2, it is easy to replace the atomizer 2.

[0073] In other examples, the power supply component 1 and the atomizer 2 can also be fixedly connected. The power supply component 1 and the atomizer 2 can be housed in the same housing structure. For example, the liquid storage tank housing 211 can also be configured to house the power supply component 1, which is connected to the base 212, making the aerosol generating device structure more compact.

[0074] The power supply component 1 may include a battery bracket 13 and a circuit structure, wherein the battery bracket 13 may be used to mount at least a portion of the circuit structure.

[0075] Figure 7 This is a schematic diagram of a power supply component provided in an embodiment of this application, as an example, such as... Figure 7 As shown, the circuit structure may include a circuit board 12 and a battery 14, with the battery 14 electrically connected to the circuit board 12.
