[0002] Common aerosol generation devices include a liquid storage component, an atomizing component, and a power supply component. The liquid storage component stores the aerosol matrix. During operation, the power supply component supplies power to the atomizing component, which heats the aerosol matrix to form an aerosol.

[0003] The storage component can only hold a limited amount of aerosol matrix. Once the aerosol matrix is ​​exhausted, the entire aerosol generation device or part of it will be rendered unusable, resulting in significant waste. Utility Model Content

[0004] This application provides a liquid storage component, an atomizer, and an aerosol generating device, which facilitates the replenishment of the aerosol matrix, extends the service life of the aerosol generating device, and reduces waste. The technical solution is as follows:

[0005] In a first aspect, embodiments of this application provide a liquid storage assembly, which includes a liquid reservoir shell, a liquid storage component, and a liquid guide tube. The liquid storage component is located in the liquid reservoir shell, and there is a gap between the liquid storage component and the inner wall of the liquid reservoir shell. The liquid reservoir shell has a first injection hole, which communicates with the gap. The liquid guide tube is located outside the liquid reservoir shell, and one end of the liquid guide tube communicates with the first injection hole.

[0006] In some examples, the reservoir is cylindrical, and the gap is located at one end of the reservoir.

[0007] In some examples, the liquid reservoir housing has a suction nozzle connection, and the gap is located between the suction nozzle connection and the liquid storage component.

[0008] In some examples, the liquid guide tube is a bend, and the vertical distance from the end of the liquid guide tube away from the first injection hole to the end face of the liquid storage component is greater than the vertical distance from the first injection hole to the end face of the liquid storage component.

[0009] In some examples, the inner wall of the liquid reservoir housing has a limiting protrusion located in the gap, and the liquid storage component abuts against the limiting protrusion.

[0010] In some examples, the liquid storage assembly also includes a one-way valve located in the liquid delivery tube.

[0011] Secondly, embodiments of this application also provide an atomizer, the atomizer including an atomizing component and any of the liquid storage components described in the first aspect, the atomizing component being located in the liquid storage component.

[0012] In some examples, the atomizer further includes a housing assembly, in which the liquid reservoir assembly is located, the housing assembly having a second liquid inlet, and the end of the liquid guide tube remote from the first liquid inlet communicating with the second liquid inlet.

[0013] In some examples, the atomizer also includes a sealing plug located in the second injection port.

[0014] Thirdly, embodiments of this application also provide an aerosol generating device, which includes an atomizing component, a power supply component, a housing component, and any of the liquid storage components described in the first aspect. The atomizing component is located in the liquid storage component, and both the liquid storage component and the power supply component are located in the housing component. The power supply component is used to supply power to the atomizing component. The housing component has a second liquid injection port, and the end of the liquid guide tube away from the first liquid injection port is connected to the second liquid injection port; or...

[0015] It includes a power supply component and any of the atomizers described in the second aspect, wherein the power supply component is connected to the atomizer and is used to supply power to the atomizer.

[0016] The beneficial effects of the technical solutions provided in this application include at least the following:

[0017] By arranging a liquid storage component within the liquid reservoir shell, an aerosol matrix can be stored. A liquid guide pipe is arranged outside the liquid reservoir shell, with one end connected to the first injection port of the liquid reservoir shell, allowing the aerosol matrix to be replenished into the liquid reservoir shell via the liquid guide pipe. Because there is a gap between the liquid storage component and the inner wall of the liquid reservoir shell, and the first injection port is connected to this gap, the liquid storage component will not block the first injection port during the replenishment of the aerosol matrix via the liquid guide pipe. This allows the aerosol matrix to smoothly enter the gap and be gradually absorbed by the liquid storage component, facilitating the replenishment of the aerosol matrix, extending the service life of the aerosol generation device, and reducing waste.

[0037] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1As shown, the aerosol generating device includes a power supply component 100 and an atomizer 200. The power supply component 100 supplies power to the atomizer 200. The atomizer 200 can be detachably connected to the power supply component 100 or fixedly connected.

[0038] Figure 2 This is a schematic diagram of the internal structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 2 As shown, the atomizer 200 includes a liquid storage assembly 210 and an atomizing assembly 220. The liquid storage assembly 210 is used to store the aerosol matrix. The atomizing assembly 220 is located in the liquid storage assembly 210 and is used to heat the aerosol matrix to form an aerosol.

[0039] The liquid storage assembly 210 may include a liquid reservoir housing 211 and a liquid storage component 213. The liquid reservoir housing 211 forms a liquid reservoir for containing the aerosol matrix. The liquid storage component 213 is located within the liquid reservoir housing 211.

[0040] The liquid storage assembly 210 may also include a sealing base 212, which may be fixedly connected to or detachably connected to the liquid reservoir housing 211. The sealing base 212 may be used to mount electrodes for electrical connection to the power supply assembly 100.

[0041] The aerosol matrix that can be contained in the liquid tank is relatively limited. After the aerosol matrix in the liquid tank is exhausted, the liquid storage component 210 needs to be disassembled to replenish the aerosol matrix. Therefore, the atomizer 200 is usually directly discarded. For aerosol generating devices that cannot be disassembled separately, even the entire aerosol generating device will be discarded, resulting in huge waste.

[0042] Figure 3 This is a schematic diagram of the structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 3 As shown, the liquid storage assembly includes a liquid reservoir housing 211, a liquid storage component 213, and a liquid guide pipe 214. The liquid storage component 213 is located within the liquid reservoir housing 211.

[0043] Figure 4 This is a schematic diagram of the internal structure of a liquid storage component provided in an embodiment of this application, as shown below. Figure 4 As shown, there is a gap 210a between the liquid storage component 213 and the inner wall of the liquid tank housing 211. The liquid tank housing 211 has a first injection hole 211a, which communicates with the gap 210a. The liquid guide tube 214 is located outside the liquid tank housing 211, and one end of the liquid guide tube 214 communicates with the first injection hole 211a.

[0044] A liquid storage component 213 is arranged inside the liquid reservoir housing 211, which can store the aerosol matrix. A liquid guide pipe 214 is arranged outside the liquid reservoir housing 211, with one end of the pipe connected to the first injection hole 211a of the liquid reservoir housing 211, allowing the aerosol matrix to be replenished into the liquid reservoir housing 211 through the pipe 214. Because there is a gap 210a between the liquid storage component 213 and the inner wall of the liquid reservoir housing 211, and the first injection hole 211a is connected to the gap 210a, the liquid storage component 213 will not block the first injection hole 211a during the replenishment of the aerosol matrix through the liquid guide pipe 214. This allows the aerosol matrix to smoothly enter the gap 210a and be gradually absorbed by the liquid storage component 213, facilitating the replenishment of the aerosol matrix, extending the service life of the aerosol generation device, and reducing waste.

[0045] The liquid storage component 213 has numerous pores. After contacting the aerosol matrix, the liquid storage component 213 gradually adsorbs the aerosol matrix into its interior. In this embodiment, the first injection hole 211a is connected to the gap 210a, meaning that the first injection hole 211a is directly connected to the gap 210a. The aerosol matrix entering the liquid tank shell 211 through the first injection hole 211a can reach the gap 210a without passing through the pores in the liquid storage component 213.

[0046] The absorption rate of the aerosol matrix by the liquid storage device 213 is limited. In this embodiment, since the first injection hole 211a is connected to the gap 210a, the liquid storage device 213 does not block the first injection hole 211a. This allows the aerosol matrix to enter the gap 210a without obstruction and then be gradually absorbed by the liquid storage device 213, making the addition process of the aerosol matrix fast and smooth.

[0047] For example, the liquid storage component 213 can be a liquid storage cotton, which is used to adsorb or wet the aerosol matrix.

[0048] like Figure 3 As shown, the liquid storage component 213 is cylindrical. (Refer to...) Figure 4 The gap 210a can be located at one end of the liquid storage component 213.

[0049] The gap 210a is arranged at the end of the liquid reservoir 213, so that the aerosol matrix mainly enters the liquid reservoir 213 from the end of the liquid reservoir 213. By absorbing the aerosol matrix at the end, the liquid reservoir 213 can more quickly and evenly disperse the aerosol matrix throughout the liquid reservoir 213.

[0050] like Figure 3 As shown, the liquid reservoir housing 211 has a suction nozzle connection port 211b, and a gap 210a is located between the suction nozzle connection port 211b and the liquid storage component 213. In this example, the suction nozzle connection port 211b is opposite to one end of the liquid storage component 213.

[0051] The nozzle connector 211b is used to connect the nozzle 215. When the user holds the atomizer 200 or aerosol generator, the nozzle 215 is typically facing upwards. A gap 210a is located between the nozzle connector 211b and the reservoir 213, allowing the aerosol matrix added to the gap 210a to enter and disperse more quickly throughout the reservoir 213 under gravity.

[0052] In some examples, the liquid storage assembly 210 may include a suction nozzle 215, which may be connected to the liquid reservoir housing 211. For example, the suction nozzle 215 may be detachably connected to the liquid reservoir housing 211, or the suction nozzle 215 may be fixedly connected to the liquid reservoir housing 211.

[0053] like Figure 4 As shown, the liquid guide tube 214 is a curved tube. The vertical distance from the end of the liquid guide tube 214 away from the first injection hole 211a to the end face of the liquid storage component 213 is greater than the vertical distance from the first injection hole 211a to the end face of the liquid storage component 213. In other words, when the user holds the atomizer 200 or aerosol generating device with the nozzle 215 facing upwards, the two ends of the liquid guide tube 214 are at different heights, with the end of the liquid guide tube 214 away from the first injection hole 211a being higher. This makes it easier for the aerosol matrix to be added into the liquid tank housing 211 through the liquid guide tube 214, preventing the aerosol matrix from overflowing from the liquid guide tube 214.

[0054] The liquid guide tube 214 can be detachably connected to the liquid reservoir housing 211. For example, the outer wall of the liquid reservoir housing 211 can have a first connector 2111 communicating with the first injection hole 211a, and one end of the liquid guide tube 214 can be fitted over the first connector 2111. Thus, when manufacturing the liquid reservoir housing 211 of the liquid storage component 210 in this embodiment, the liquid guide tube 214 can be assembled to the liquid reservoir housing 211 after the liquid reservoir housing 211 and the liquid guide tube 214 are manufactured separately. The liquid reservoir housing 211 in this embodiment can also be used when manufacturing disposable atomizers or aerosol generating devices (i.e., atomizers or aerosol generating devices that cannot repeatedly add aerosol matrix). After manufacturing the liquid reservoir housing 211, the first connector 2111 only needs to be sealed, for example, with sealant or a sealing plug. This allows for manufacturing using a single mold, reducing equipment costs.

[0055] In some other possible implementations, the liquid guide tube 214 may also be fixedly connected to the liquid tank housing 211. For example, the liquid guide tube 214 and the liquid tank housing 211 may be integrally formed.

[0056] In some implementations, the liquid guide tube 214 can be a flexible tube, which allows the liquid guide tube 214 to be bent as needed during the assembly of the atomizer 200 or the aerosol generating device, making assembly convenient.

[0057] In some examples, the reservoir assembly may also include a one-way valve located in the liquid delivery line 214.

[0058] By setting a one-way valve in the liquid guide tube 214, the liquid can only flow into the liquid tank housing 211 from the end of the liquid guide tube 214 away from the first injection hole 211a, and cannot flow in the reverse direction, which can further prevent the aerosol matrix from overflowing from the liquid guide tube 214.

[0059] As an example, the one-way valve may include a spring and a sealing ball, which, under the elastic force of the spring, seals the lumen of the liquid guide tube 214. When an aerosol matrix is ​​injected from the end of the liquid guide tube 214 away from the first injection port 211a, the aerosol matrix can push the sealing ball, opening the lumen of the liquid guide tube 214.

[0060] In some other possible implementations, the one-way valve may include a one-way diaphragm. When the aerosol matrix is ​​injected from the end of the liquid guide tube 214 away from the first injection hole 211a, the one-way diaphragm deforms towards the side closer to the first injection hole 211a under the pressure of the aerosol matrix, allowing the aerosol matrix to pass through normally.

[0061] like Figure 4 As shown, the inner wall of the liquid tank housing 211 has a limiting protrusion 2112, which is located in the gap 210a, and the liquid storage component 213 abuts against the limiting protrusion 2112.

[0062] Setting a limiting protrusion 2112 to limit the liquid storage component 213 can prevent the liquid storage component 213 from moving in the liquid tank shell 211 and blocking the first injection hole 211a, ensuring that the aerosol matrix can be added smoothly.

[0063] For example, there may be multiple limiting protrusions 2112, which are circumferentially distributed on the inner wall of the liquid reservoir housing 211. The end of the liquid storage component 213 near the nozzle connection port 211b abuts against the multiple limiting protrusions 2112.

[0064] As an example, the limiting protrusion 2112 can be a ridge. In other possible implementations, the limiting protrusion 2112 can also be a bump.

[0065] As another example, the limiting protrusion 2112 can be an inner flange.

[0066] Figure 5 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application, as shown below. Figure 5 As shown, the atomizer includes an atomizing component 220 and, as shown, ... Figure 3 or Figure 4In any of the liquid storage components 210 shown, the atomizing component 220 is located in the liquid storage component 213.

[0067] The atomizing component 220 is used to heat the aerosol matrix, and the atomizing component 220 has an atomizing channel 220a.

[0068] The atomizing assembly 220 includes a support cylinder 221, a liquid guide 222, a heating element 223, and a pin 224. The support cylinder 221 forms an atomizing channel 220a, and the liquid guide 222 and the heating element 223 are located within the support cylinder 221. The pin 224 is electrically connected to the heating element 223.

[0069] The support cylinder 221 provides space inside the liquid tank shell 211 to accommodate the liquid guiding component 222 and the heating component 223. The wall of the support cylinder 221 may have structures such as holes and slits to allow the aerosol matrix in the liquid tank shell 211 to enter the atomization channel 220a and be absorbed by the liquid guiding component 222. The heating component 223 is used to heat the aerosol matrix in the liquid guiding component 222, causing the aerosol matrix to vaporize.

[0070] 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.

[0071] One end of pin 224, located outside the support cylinder 221, passes through the sealing base 212 and contacts the electrode mounted on the sealing base 212.

[0072] Figure 6 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application, as shown below. Figure 6 As shown, the atomizer also includes a housing assembly 230, and a liquid storage assembly 210 is located in the housing assembly 230. The housing assembly 230 has a second liquid injection port 230a, and the end of the liquid guide tube 214 away from the first liquid injection port 211a is connected to the second liquid injection port 230a.

[0073] By providing a second liquid injection hole 230a in the housing assembly 230 and connecting it to the liquid guide tube 214, it is convenient to add the aerosol matrix from outside the atomizer.

[0074] The housing assembly 230 may have a second connector 231 communicating with the second injection port 230a, and the end of the liquid guide tube 214 away from the first injection port 211a may be fitted over the second connector 231.

[0075] like Figure 6 As shown, the atomizer may also include a sealing plug 232, which is located in the second injection port 230a.

[0076] Setting a sealing plug 232 in the second injection hole 230a can prevent leakage of the aerosol matrix and also prevent foreign objects from entering the liquid guide tube 214.

[0077] For example, the sealing plug 232 can be a rubber plug or a silicone plug, so that the elasticity of the sealing plug 232 can be used to form an interference fit between the sealing plug 232 and the second injection hole 230a.

[0078] Figure 7 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 7 As shown, the aerosol generating device includes a power supply component 100 and a power supply unit 100. Figure 6 The atomizer 200 shown has a power supply component 100 connected to it, which supplies power to the atomizer 200. The atomizer 200 and the power supply component 100 can be detached or fixedly connected.

[0079] Figure 8 This is a schematic diagram of the internal structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 8 As shown, the aerosol generating device includes an atomizing component 220, a power supply component 100, a housing component 230, and as shown in the figure. Figure 3 or Figure 4 The liquid storage assembly 210 is shown. The atomizing assembly 220 is located in the liquid storage component 213, and both the liquid storage assembly 210 and the power supply assembly 100 are located in the housing assembly 230. The power supply assembly 100 is used to supply power to the atomizing assembly 220. The housing assembly 230 has a second liquid injection port 230a, and the end of the liquid guide tube 214 away from the first liquid injection port 211a is connected to the second liquid injection port 230a.

[0080] In this aerosol generating device, the atomizing component 220, the power supply component 100, and the liquid storage component 210 share a housing component 230.

[0081] Figure 9 This is a schematic diagram of the external structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 9 As shown, the second injection port 230a can be located on one side of the nozzle 215, and the sealing plug 232 is located in the second injection port 230a. When holding the aerosol generating device, users are usually accustomed to keeping the nozzle 215 facing upwards and arranging the second injection port 230a on one side of the nozzle 215. When it is necessary to remove the sealing plug 232 to add the aerosol matrix, the user can still hold the aerosol generating device in the usual way, which is convenient for operation.

[0082] By arranging a liquid guide pipe 214 in the aerosol generating device, with one end of the liquid guide pipe 214 connected to the first injection hole 211a of the liquid tank shell 211, aerosol matrix can be replenished into the liquid tank shell 211 through the liquid guide pipe 214. Since there is a gap 210a between the liquid storage component 213 and the inner wall of the liquid tank shell 211, and the first injection hole 211a is connected to the gap 210a, the liquid storage component 213 will not block the first injection hole 211a during the replenishment of the aerosol matrix through the liquid guide pipe 214. This allows the aerosol matrix to smoothly enter the gap 210a and be gradually absorbed by the liquid storage component 213, facilitating the replenishment of the aerosol matrix, extending the service life of the aerosol generating device, and reducing waste.

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.
