Abstract

This application provides a heating mesh, a heating element, an atomizing assembly, an atomizer, and an aerosol generating device, belonging to the field of aerosol generating devices. The heating mesh includes a heating section and pin connection sections located at both ends of the heating section. The heating section has two first heating zones, one of which is near one end of the heating section, and the other is near the other end. The linewidth of the first heating zone gradually increases in the direction away from the pin connection section. The linewidth affects the heat generation of the heating mesh during energized operation; decreasing the linewidth increases the heating power, while increasing the linewidth decreases the power. By gradually increasing the linewidth in the first heating zone in the direction away from the pin connection section, the heat generation in the area near the pin connection section increases, while the heat generation in the area away from the pin connection section decreases. This makes the heating of the heating section more uniform, avoids excessively high local temperatures, improves the atomization effect, and extends the life of the atomizer.

Description

Technical Field

[0001] This application relates to the field of aerosol generating devices, and in particular to a heating mesh, a heating element, an atomizing assembly, an atomizer, and an aerosol generating device. Background Technology

[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] The atomizing components in an atomizer include a heating element and a liquid guiding element. The liquid guiding element is fitted over the heating element, which is used to heat the aerosol matrix to form an aerosol.

[0004] Currently, it has been found that some atomizing components have significantly reduced atomization efficiency after a period of use, resulting in a relatively short lifespan for the atomizer. Utility Model Content

[0005] This application provides a heating mesh, a heating element, an atomizing assembly, an atomizer, and an aerosol generating device, which can extend the service life of the atomizer. The technical solution is as follows:

[0006] In a first aspect, embodiments of this application provide a heating mesh for an atomizing component. The heating mesh includes a heating part and pin connection parts located at both ends of the heating part. The heating part has two first heating areas, one of which is close to one end of the heating part, and the other of which is close to the other end of the heating part.

[0007] The linewidth of the first heating zone gradually increases in the direction away from the pin connection portion.

[0008] In some examples, the linewidth of the first heating zone increases continuously in the direction away from the pin connection.

[0009] In some examples, the first heating area includes multiple sub-regions arranged along the length of the heating element. The line width of the same sub-region is the same. Along the direction away from the pin connection portion, the line width of the multiple sub-regions increases sequentially. The length of the heating element refers to the direction from one end of the heating element to the other end.

[0010] In some examples, the line width difference between adjacent sub-regions in the plurality of sub-regions is a positive integer multiple of a unit difference Δd, where the unit difference Δd is the minimum of the line width differences among all adjacent sub-regions in the plurality of sub-regions.

[0011] In some examples, the line width difference between adjacent sub-regions is the same.

[0012] In some examples, the unit difference Δd is 0.005mm to 0.04mm.

[0013] In some examples, the width of the sub-region is a positive integer multiple of a unit distance F, which is the distance between the geometric centers of adjacent meshes along the length of the heating element, and the width direction of the sub-region is parallel to the length direction of the heating element.

[0014] In some examples, the first heating area includes four sub-regions. Within the same first heating area, along the direction away from the pin connection, the widths of the first sub-region, the second sub-region, and the fourth sub-region are the same, and the width of the third sub-region is twice the width of the first sub-region.

[0015] In some examples, the maximum linewidth of the first heating zone is 0.05mm to 0.32mm.

[0016] In some examples, the heating element also has a second heating area located between the two first heating areas; the line width of the second heating area is smaller than the maximum line width of the first heating area.

[0017] In some examples, the width of the second heating zone is smaller than the width of the first heating zone, and the width directions of both the first and second heating zones are parallel to the direction from one end of the heating element to the other.

[0018] In some examples, the heating mesh further includes a heat dissipation section distributed between the two pin connection sections and connected to the edge of the heating section; the line width of the heat dissipation section is 0.08mm~0.38mm.

[0019] Secondly, embodiments of this application also provide a heating element, which includes any of the heating meshes described in the first aspect and two pins, wherein the two pins are respectively connected to the pin connection portion of the heating mesh.

[0020] Thirdly, embodiments of this application also provide an atomizing component, the atomizing component including a liquid guiding element and a heating element as described in the second aspect, wherein the two ends of the heating mesh are bent relative to each other into a cylindrical shape, and the liquid guiding element is sleeved on the heating mesh.

[0021] Fourthly, embodiments of this application also provide an atomizer, the atomizer comprising:

[0022] Liquid storage components for storing aerosol matrix;

[0023] The atomizing component as described in the third aspect is located in the liquid storage component, and the atomizing component is used to heat the aerosol matrix.

[0024] Fifthly, embodiments of this application also provide an aerosol generating device, the aerosol generating device including a power supply component and an atomizer as described in the fourth aspect, the power supply component being used to supply power to the atomizing component.

[0025] The beneficial effects of the technical solutions provided in this application include at least the following:

[0026] By arranging pin connections at both ends of the heating element of the heating mesh, the heating element can be powered by connecting pins. Two first heating zones are arranged near the two ends of the heating element. Line width affects the heat generation of the heating mesh during operation; decreasing the line width increases heating power, while increasing it decreases power. By gradually increasing the line width in the first heating zones away from the pin connections, the heat generation in the area near the pin connections increases, while the heat generation in the area away from the pin connections decreases. This reduces the heat generation difference between the end and central areas of the heating element, helping to reduce temperature differences between different areas and making the overall heating more uniform. This prevents localized overheating that could accelerate the aging of the heating mesh and affect atomization performance, thus improving the atomization effect and extending the atomizer's lifespan.

[0045] 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 1 As shown, the aerosol generating device includes a power supply component 100 and an atomizer 200. The power supply component 100 is used to supply power to the atomizer 200.

[0046] Figure 2 This is a schematic diagram of the internal structure of an atomizer 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. The atomizing assembly 220 has an atomizing channel 220a.

[0047] The liquid storage assembly 210 may include a liquid reservoir housing 211, the interior of which forms a liquid reservoir for containing the aerosol matrix. The liquid storage assembly 210 may also include a base 212, which may be fixedly connected to or detachably connected to the liquid reservoir housing 211. The base 212 may be used to mount electrodes 2121 for electrical connection to the power supply assembly 100.

[0048] In some examples, the liquid storage assembly 210 may also include a liquid storage element, such as a liquid storage cotton that has been adsorbed / wetted with an aerosol matrix.

[0049] The atomizing assembly 220 is located in the liquid tank housing 211. The atomizing assembly 220 includes a support 221, a liquid guide 222, and a heating element 223. The support 221 forms an atomizing channel 220a, and the liquid guide 222 and the heating element 223 are located in the support 221.

[0050] The support 221 provides space inside the liquid tank housing 211 to accommodate the liquid guiding component 222 and the heating component 223. The support 221 may be cylindrical, and its wall may have structures such as holes and slits to allow the aerosol matrix in the liquid tank housing 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.

[0051] 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.

[0052] Figure 3 A schematic diagram of a heating element is shown, such as... Figure 3 As shown, the heating element 223 includes a heating mesh 30 and two pins 224, which are connected to both ends of the heating mesh 30. Figure 3 The heating element 223 shown is in a flattened state. During the assembly into the atomizing component 220, the two ends of the heating mesh 30 are bent relative to each other, causing the heating mesh 30 to curl into a cylindrical shape. The heating mesh 30 operates based on the electrothermal effect. During operation, the heating mesh 30 is powered by the pins 224 connected to both ends. Current flows through the heating mesh 30 to do work and generate heat.

[0053] The heating mesh 30 has a grid structure with multiple mesh openings arranged in an array. The mesh openings in different areas of the heating mesh 30 are of equal size and line width. Figure 4 yes Figure 3 The temperature distribution cloud diagram of the heating mesh when the heating element is working is shown below. Figure 4 As shown, the temperature in the center of the heating mesh 30 is high, while the temperature at both ends of the heating mesh 30 is low, resulting in a very uneven temperature distribution. This makes it prone to localized overheating. Areas with higher temperatures age faster, and localized overheating will significantly shorten the lifespan of the heating mesh 30. Consequently, after a period of operation, the atomizing component 220 will experience a significant decrease in atomization efficiency, affecting the lifespan of the atomizer 200.

[0054] Figure 5This is a schematic diagram of the heating mesh of an atomizing component provided in an embodiment of this application. Figure 5 As shown, the heating mesh 30 includes a heating part 31 and pin connection parts 32 located at both ends of the heating part 31. The heating part 31 has two first heating areas 31a, one of which is close to one end of the heating part 31, and the other of which is close to the other end of the heating part 31.

[0055] The linewidth of the first heating zone 31a gradually increases in the direction away from the pin connection portion 32.

[0056] The heating element 31 is surrounded by heating wires in a grid shape. In this embodiment, the line width refers to the width of the heating wire. For example, the line width of the first heating area 31a refers to the width of the heating wire in the first heating area 31a.

[0057] In the embodiments of this application, the direction away from the pin connection portion 32 refers to the direction away from the closer of the two pin connection portions 32. For example, Figure 5 In the middle, for the first heating area 31a on the left, the line width gradually increases in the direction away from the pin connection portion 32, which means that the line width gradually increases in the direction away from the left pin connection portion 32; for the first heating area 31a on the right, the line width gradually increases in the direction away from the pin connection portion 32, which means that the line width gradually increases in the direction away from the right pin connection portion 32.

[0058] By arranging pin connection portions 32 at both ends of the heating part 31 of the heating mesh 30, the pin connection portions 32 can be used to connect pins 224 to supply power to the heating part 31. Two first heating areas 31a are arranged on the heating part 31, located near both ends of the heating part 31. The line width affects the heat generation of the heating mesh 30 during energized operation; reducing the line width increases the heating power, while increasing the line width decreases the power. Figure 6 yes Figure 5 The temperature distribution cloud map shown is as follows when the heating mesh is in operation. Figure 6 As shown, by gradually increasing the line width in the first heating zone 31a along the direction away from the pin connection portion 32, the heat generation in the area of ​​the first heating zone 31a near the pin connection portion 32 increases, while the heat generation in the area away from the pin connection portion 32 decreases. This reduces the heat generation difference between the end area and the central area of ​​the heating part 31, which helps to reduce the temperature difference between different areas of the heating part 31, making the overall heating of the heating part 31 more uniform. It also avoids excessively high local temperatures that could accelerate the aging of the heating mesh 30 and affect the atomization effect, thus improving the atomization effect of the atomizer 200 and extending the service life of the atomizer 200.

[0059] The heating mesh 30 operates based on the electrothermal effect; when current passes through a conductor, the heating power of the conductor is equal to I. 2 The result is related to R, where I represents the current in the conductor and R represents the resistance of the conductor. Qualitative analysis can be performed based on this principle. For Figure 3 The heating element 223 shown has a uniform line width across the heating mesh 30. The heating mesh 30 generates more heat near the center and less heat near the ends. For Figure 5 In the heating element 30 shown, within the first heating zone 31a, the linewidth is smaller in the area near the pin connection portion 32 and larger in the area farther from the pin connection portion 32. Reducing the linewidth increases resistance, and increasing the linewidth decreases resistance. (Comparison...) Figure 3 The heating element 223 shown is equivalent to increasing the heating power in the area near the pin connection 32 and reducing the heating power in the area near the center, thereby making the temperature distribution more uniform when the heating mesh 30 is heated.

[0060] In some examples, the linewidth of the first heating region 31a can be continuously increased in the direction away from the pin connection portion 32. The continuous variation in the linewidth of the first heating region 31a can better reduce the temperature gradient of the heating part 31 and make the temperature distribution of the heating part 31 more uniform.

[0061] In this example, the first heating area 31a includes multiple sub-regions 31b, which are arranged along the length of the heating part 31. The linewidth of the same sub-region 31b is the same, and the linewidth of the multiple sub-regions 31b increases sequentially along the direction away from the pin connection part 32.

[0062] The length direction of the heating element 31 refers to the direction from one end of the heating element 31 to the other end.

[0063] In this example, by dividing the first heating zone 31a into multiple sub-regions 31b, and using a fixed line width within the same sub-region 31b, the processing difficulty of the heating mesh 30 can be reduced, and the production cost can be lowered.

[0064] With the size of the first heating zone 31a remaining constant, the more sub-regions 31b there are, the smaller the temperature gradient between adjacent sub-regions 31b, which is more conducive to improving the uniformity of temperature distribution. Correspondingly, the more sub-regions 31b there are, the more difficult it is to process the heating mesh 30. As an example, the first heating zone 31a can include four sub-regions 31b, which results in higher uniformity of temperature distribution and relatively lower processing difficulty.

[0065] Figure 7 This is a partial structural diagram of a heating mesh provided in an embodiment of this application, as shown below. Figure 7As shown, among the multiple sub-regions 31b, the difference in line width between adjacent sub-regions 31b can be a positive integer multiple of the unit difference Δd.

[0066] The unit difference Δd is the minimum difference in linewidth among all adjacent sub-regions 31b in the plurality of sub-regions 31b. For example, in the same first heating area 31a, along the direction away from the pin connection portion 32, the minimum of the linewidth differences between the fourth sub-region 31b and the third sub-region 31b, the linewidth differences between the third sub-region 31b and the second sub-region 31b, and the linewidth differences between the second sub-region 31b and the first sub-region 31b is the unit difference Δd.

[0067] By adjusting the linewidth of adjacent sub-regions 31b, the temperature distribution of the heating mesh 30 can be changed. Setting a unit difference as the minimum adjustment unit for the linewidth facilitates its adjustment. During the design process, the linewidth of adjacent sub-regions 31b can be continuously fine-tuned based on the temperature distribution cloud map of the heating mesh 30, thereby making the temperature distribution of the heating part 31 more uniform and meeting the design requirements.

[0068] As an example, the line width difference between the 4th sub-region 31b and the 3rd sub-region 31b is 1 times the unit difference Δd, i.e., Δd; the line width difference between the 3rd sub-region 31b and the 2nd sub-region 31b is 2 times the unit difference Δd, i.e., 2Δd; and the line width difference between the 2nd sub-region 31b and the 1st sub-region 31b is 1 times the unit difference Δd, i.e., Δd.

[0069] In some other possible implementations, the line width difference between adjacent sub-regions 31b is the same. That is, the line width difference between adjacent sub-regions 31b is 1 times the unit difference Δd, meaning that the line width difference between adjacent sub-regions 31b is equal to the unit difference Δd, and the line widths of multiple sub-regions 31b form an arithmetic sequence.

[0070] The line width of each sub-region 31b adopts a relatively regular variation pattern of arithmetic sequence, which facilitates the design of the heating mesh 30.

[0071] In some examples, the unit difference Δd can be 0.005mm to 0.04mm.

[0072] The smaller the difference in linewidth between adjacent sub-regions 31b, the smaller the temperature gradient between them, and the more precise the adjustment of the temperature distribution. Setting the unit difference Δd to 0.005mm~0.04mm allows for relatively fine adjustment of the linewidth difference between adjacent sub-regions 31b, and can also significantly improve the temperature distribution of the heating element 31 when the number of sub-regions 31b is small.

[0073] like Figure 7As shown, the width of sub-region 31b can be a positive integer multiple of the unit distance F, where the unit distance F is the distance between the geometric centers of adjacent meshes along the length of the heating element 31. The width direction of sub-region 31b is parallel to the length direction of the heating element 31.

[0074] The mesh can be polygonal, such as the regular hexagon in this example. In other possible implementations, the mesh can also be rectangular, rhomboid, regular octagon, etc.

[0075] The mesh of the heating mesh 30 is arranged in an array. Along the length of the heating element 31, the structure of the heating mesh 30 is periodic. The smallest repeating unit is the portion between the geometric centers of adjacent meshes along the length of the heating element 31, with a width of a unit distance F. Setting the width of the sub-region 31b to a positive integer multiple of the unit distance F allows for easy adjustment of the width of each sub-region 31b during the design process, altering the temperature distribution of the heating element 31 and making the temperature distribution of the heating element 31 more uniform.

[0076] As an example, such as Figure 7 As shown, the first heating region 31a includes four sub-regions 31b. Within the same first heating region 31a, along the direction away from the pin connection portion 32, the widths of the first sub-region 31b, the second sub-region 31b, and the fourth sub-region 31b are the same, and the width of the third sub-region 31b is twice the width of the first sub-region 31b.

[0077] For example, in the same first heating area 31a, along the direction away from the pin connection portion 32, i.e. Figure 7 In the direction from left to right, the width of the first sub-region 31b, the width of the second sub-region 31b, and the width of the fourth sub-region 31b are all 1 unit distance F, and the width of the third sub-region 31b is 2 unit distance F.

[0078] The third sub-region 31b is closer to the center of the heating element 31. Setting the width of the third sub-region 31b to twice the width of the other sub-regions 31b can prevent the gradient of the line width change in the region close to the center of the heating element 31 from being too large, which would cause the area with higher temperature in the heating element 31 to shift excessively to both ends of the heating element 31 and affect the uniformity of temperature distribution.

[0079] like Figure 5 As shown, the heating element 31 may also have a second heating region 31c, which is located between the two first heating regions 31a. The linewidth of the second heating region 31c is smaller than the maximum linewidth of the first heating region 31a.

[0080] The maximum linewidth of the first heating zone 31a refers to the linewidth at the point of maximum linewidth within the first heating zone 31a. For example, in this example, the maximum linewidth of the first heating zone 31a is the linewidth d of the fourth sub-region 31b.

[0081] The central part of the heating part 31 is the main heating part. By arranging a second heating part 31c between the two first heating parts 31a, and the line width of the second heating part 31c is smaller than the line width of the area adjacent to the second heating part 31c, the area with a high temperature of the heating part 31 can be prevented from shifting excessively to both ends of the heating part 31, resulting in the temperature of the central part being too low and affecting the heating performance of the heating part 31.

[0082] As an example, the difference between the maximum linewidth of the first heating zone 31a and the linewidth of the second heating zone 31c can be a positive integer multiple of the unit difference Δd, for example, one time the unit difference Δd. In this example, the linewidth of the second heating zone 31c can be the same as the linewidth of the third sub-region 31b.

[0083] In some examples, the maximum linewidth of the first heating zone 31a can be 0.05mm to 0.32mm. For example, the maximum linewidth of the first heating zone 31a can be 0.26mm.

[0084] Setting the maximum linewidth to 0.05mm~0.32mm avoids excessive resistance and temperature at the maximum linewidth location. Simultaneously, it prevents the minimum linewidth of the first heating zone 31a from being too small, which could lead to localized overheating or even burnout of the heating mesh 30. The minimum linewidth of the first heating zone 31a refers to the linewidth at the point of minimum width within the first heating zone 31a. For example, the maximum linewidth of the first heating zone 31a is the linewidth of the first sub-region 31b.

[0085] As an example, the line width of the first sub-region 31b can be 0.18mm, the line width of the second sub-region 31b can be 0.20mm, the line width of the third sub-region 31b can be 0.24mm, and the line width of the fourth sub-region 31b can be 0.26mm. The line width of the second heating area 31c can be 0.24mm.

[0086] In some examples, the width of the second heating zone 31c is smaller than the width of the first heating zone 31a to avoid the second heating zone 31c being too wide, which would cause the central part of the heating element 31 to overheat. The width direction of the first heating zone 31a and the width direction of the second heating zone 31c are both parallel to the direction from one end of the heating element 31 to the other end, that is, parallel to the length direction of the heating element 31.

[0087] For example, the width of the second heating zone 31c can be 3 units.

[0088] like Figure 5 As shown, the heating mesh 30 may also include a heat dissipation part 33, which is distributed between the two pin connection parts 32 and connected to the edge of the heating part 31.

[0089] The heat dissipation part 33 is connected to the edge of the heating part 31. When the heating mesh 30 is working, it can dissipate heat and prevent the heating mesh 30 from getting too hot and affecting the heating effect.

[0090] like Figure 7 As shown, in some examples, the linewidth D of the heat sink 33 can be 0.08mm to 0.38mm. For example, the linewidth of the heat sink 33 is 0.22mm.

[0091] The larger the linewidth of the heat dissipation part 33, the larger its heat dissipation area, and vice versa. Setting the linewidth of the heat dissipation part 33 to 0.08mm~0.38mm can avoid the heat dissipation area of ​​the heat dissipation part 33 being too small and affecting heat dissipation, while also avoiding the heat dissipation area being too large and causing the edge of the heating part 31 to have a lower temperature, thus affecting the heating effect.

[0092] In some examples, the heating mesh 30 can be a symmetrical structure. For instance, the heating mesh 30 can be axially symmetrical, having two mutually perpendicular axes of symmetry, one extending along the length of the heating element 31 and the other along the width of the heating element 31. A symmetrical heating mesh 30 results in a symmetrical temperature distribution during heating, which improves the uniformity of the overall temperature distribution.

[0093] The heating element 30 can be made of one or more of the following: iron-chromium-aluminum alloy, nickel-chromium alloy, and stainless steel alloy, for example, iron-chromium-aluminum material. The thickness of the heating element 30 can be 0.05mm to 0.12mm. The thickness of the heating element 30 affects its resistance and thus its heating power. With a constant wire width, a smaller heating element 30 results in higher resistance, and a larger heating element 30 results in lower resistance. Setting the thickness between 0.05mm and 0.12mm prevents the heating element 30 from burning out due to excessive power, and also prevents it from becoming too weak, which would affect the heating effect.

[0094] For example, the thickness of the heating mesh 30 is 0.1 mm.

[0095] Figure 8 This is a schematic diagram of the heating element of an atomizing component provided in an embodiment of this application, as shown below. Figure 8 As shown, the heating element 223 includes any of the aforementioned heating mesh 30 and two pins 224, which are respectively connected to the pin connection portion 32 of the heating mesh 30.

[0096] For example, pin 224 can be soldered to pin connection portion 32.

[0097] In some examples, the material of pin 224 can be nickel, such as Ni200. The diameter of pin 224 can be 0.25mm to 0.8mm, for example, the diameter of pin 224 is 0.6mm.

[0098] By applying the aforementioned heating mesh 30 to the heating element 223, the line width of the first heating zone 31a of the heating part 31 of the heating mesh 30 gradually increases along the direction away from the pin connection part 32. This increases the heat generation in the area of ​​the first heating zone 31a near the pin connection part 32 and decreases the heat generation in the area away from the pin connection part 32. This reduces the difference in heat generation between the end area and the central area of ​​the heating part 31, which helps to reduce the temperature difference between different areas of the heating part 31. This makes the overall heating of the heating part 31 more uniform and avoids excessive local temperature, which would cause the heating mesh 30 to age faster and affect the atomization effect. This helps to improve the atomization effect of the atomizer 200 and extend the service life of the atomizer 200.

[0099] Figure 9 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application. Figure 9 As shown, the atomizing assembly includes a liquid guiding component 222 and a heating component 223, wherein the heating component 223 is... Figure 8 The heating element is shown. The two ends of the heating mesh 30 are bent into a cylindrical shape, and the liquid guiding element 222 is sleeved on the outside of the heating mesh 30.

[0100] The atomizing assembly may also include a support 221, which can cover the liquid guiding member 222. As an example, the structure of the support 221 can be described with reference to... Figure 2 The bracket 221 shown.

[0101] Applying the aforementioned heating element 223 to the atomizing assembly can improve the atomization effect, and the longer lifespan of the heating element 223 also helps to extend the service life of the atomizing assembly, thereby increasing the service life of the atomizer.

[0102] This application embodiment also provides an atomizer, which 200 may include a liquid storage component 210 and an atomizing component 220. The liquid storage component 210 is used to store an aerosol matrix. The structure of the liquid storage component 210 can be compared with... Figure 2 The liquid reservoir 210 in the atomizer shown is the same. The atomizer 220 can be... Figure 9 The atomizing component 220 is shown. The atomizing component 220 is located in the liquid storage component 210 and is used to heat the aerosol matrix to form an aerosol.

[0103] This application also provides an aerosol generating device, which includes a power supply component and the aforementioned atomizer 200. The power supply component 100 is used to supply power to the atomizer component 220.

[0104] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Because the power supply assembly 100 is detachably connected to the atomizer 200, it is easy to replace the atomizer 200.

[0105] In other examples, the power supply assembly 100 and the atomizer 200 may be fixedly connected. For example, the housing portion of the power supply assembly 100 and the liquid tank housing 211 of the atomizer 200 are integrally formed.
