[0028] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application. Figure 1 .like Figure 1 As shown, the aerosol generating device includes an atomizer 200 and a power supply 100, with the atomizer 200 connected to the power supply 100.

[0029] The atomizing component is the core structure of the atomizer 200. The atomizing component includes a base and an atomizing coil, with the atomizing coil mounted on the base. Figure 2 This is a schematic diagram of the structure of an atomizing core provided in an embodiment of this application. Figure 1 ,like Figure 2 As shown, the atomizing core 10 includes a base 11 and a heating wire 13, with the heating wire 13 wound around the base 11. When installing the atomizing core 10, both ends of the heating wire 13 need to pass through the base and bend them so that they contact the electrodes mounted on the base. This atomizing assembly has a complex structure and a cumbersome installation process, resulting in high production costs.

[0030] To reduce production costs, this application provides an atomizing component that is simple in structure and easy to install. Figure 3 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application. Figure 1 , Figure 4 This is a schematic diagram of the internal structure of an atomizing component provided in an embodiment of this application. Figure 4 To demonstrate the internal structure of atomizing component 1, some parts of its structure have been omitted. For example... Figure 3 and Figure 4As shown, the atomizing component 1 includes a base 20, a clamping member 30, a first sealing member 50, and an atomizing core 10. The first sealing member 50 is connected to the base 20, and the first sealing member 50 and the base 20 form an atomizing chamber 1a.

[0031] Figure 5 This is a schematic diagram of the structure of an atomizing core provided in an embodiment of this application. Figure 2 ,like Figure 5 As shown, the atomizing core 10 includes a base 11 and a heating element 12. The base 11 includes a main body 111 and a liquid inlet 112. The main body 111 has a top surface and a side surface adjacent to the top surface. The liquid inlet 112 is connected to the top surface of the main body 111, and the heating element 12 is disposed on the main body 111. The heating element 12 includes a heating part 121 and an electrical contact part 122 connected to the heating part 121. The electrical contact part 122 is disposed on the side surface. The electrical contact part 122 is used to be clamped in a clamping member 30 connected to the base 20 of the atomizing assembly 1, and contacts the clamping member 30 to form an electrical connection.

[0032] By providing a heating element 12 on a substrate 11, wherein the substrate 11 includes a main body 111 and a liquid inlet 112, the liquid inlet 112 is connected to the top surface of the main body 111, and the aerosol generating matrix can wet the atomizing core 10 through the liquid inlet 112. The heating element 12 is disposed on the main body 111 and includes a connected heating part 121 and a power connection part 122. The heating part 121 is used to generate heat, causing the aerosol generating matrix to atomize and form an aerosol. The power connection part 122 is located on the side of the main body 111. When installing the atomizing core 10, the structure for supplying power to the atomizing core only needs to abut against the side of the main body 111 and contact the power connection part 122 to form an electrical connection. The structure is simple and easy to install, which helps to reduce production costs.

[0033] For example, the substrate 11 can be made of a porous material, such as porous ceramic. The porous material facilitates the wetting of the aerosol generation matrix. The heating element 12 can be made of a metallic material and formed on the substrate 11. The heating element 12 heats up when energized, heating the aerosol generation matrix on the substrate 11, causing the aerosol generation matrix to transform into aerosols.

[0034] The heating element 12 can be formed of a metallic material. The heating element 12 can be formed of a single metallic material, for example, Al metal; the heating element 12 can also be formed of a metal composite material, that is, the heating element 12 includes a multi-layered metallic structure, for example, the heating element 12 can be formed of one of the following materials: Ti / Au, Ti / Pt, Ti / TiN / Au, Ti / TiN / Pt, Ta / Au, Ta / Pt, Ta / TaN / Au. As an example, the heating element 12 is formed of Ti / Au material, that is, the heating element 12 includes two stacked layers, one of which is a Ti metal layer and the other is an Au metal layer, and the layer in contact with the substrate 11 can be either a Ti metal layer or an Au metal layer; as another example, the heating element 12 is formed of Ti / TiN / Au material, that is, the heating element 12 includes three stacked layers, one of which is a Ti metal layer, one of which is a TiN metal layer, and the remaining layer is an Au metal layer, and the layer in contact with the substrate 11 can be either a Ti metal layer or an Au metal layer.

[0035] The material and structure of the heating element 12 are not limited, as long as it can achieve the heating function. For example, the heating element 12 can be made of a material with TCR (Temperature Coefficient of Resistance) characteristics. For example, the heating element 12 can be made of a PTC (Positive Temperature Coefficient) material. During the operation of the atomizing component 1, the temperature of the heating element 12 can be determined based on its resistance and the temperature coefficient of resistance, which facilitates the control of the heating power. This process can refer to relevant technologies.

[0036] like Figure 3 As shown, the first sealing member 50 has a liquid inlet hole 50a, the main body 111 is located in the atomizing chamber 1a, and the liquid inlet part 112 is inserted into the liquid inlet hole 50a. The clamping member 30 is connected to the base 20, and the main body 111 is mounted on the base 20 through the clamping member 30. The clamping member 30 clamps the side of the main body 111 and contacts the electrical connection part 122 to form an electrical connection.

[0037] In this atomizing assembly 1, a clamping member 30 is provided on the base 20. When installing the atomizing core 10, the clamping member 30 clamps the main body 111, thus fixing the atomizing core 10. While clamping the main body 111, the clamping member 30 also contacts the power receiving part 122 to form an electrical connection. Power can be supplied to the heating element 12 through the clamping member 30. The mechanical and electrical connections with the atomizing core 10 are achieved through a single structure, which helps to reduce the number of parts.

[0038] The heating element 12 may include at least two electrical connection parts 122, one of which can be electrically connected to the positive terminal of the power supply and the other of which can be electrically connected to the negative terminal of the power supply. With only two electrical connection parts 122, the structure is simple and the manufacturing cost is low.

[0039] The heating element 12 can also be connected to two or more electrical contacts 122. Some of these contacts 122 can be electrically connected to the positive terminal of the power supply, while others can be electrically connected to the negative terminal. By adjusting the positions of the multiple contacts 122, the current distribution in the heating element 121 can be changed, thus improving the uniformity of heating. Even if one or more contacts 122 are damaged, the heating element 12 can still be powered on and generate heat, improving its reliability.

[0040] Figure 6 This is a schematic diagram of the structure of an atomizing core provided in an embodiment of this application. Figure 3 ,like Figure 5 and Figure 6 As shown, the sides of the main body 111 may include opposing first side 111a and second side 111b, and at least one of the first side 111a and second side 111b is provided with a power receiving part 122.

[0041] In this example, both the first side 111a and the second side 111b are provided with a power receiving part 122.

[0042] When clamping the main body 111, the clamping member 30 can clamp the first side 111a and the second side 111b opposite to the main body 111, stably clamping the atomizing core 10. At least one of the first side 111a and the second side 111b is provided with a power receiving part 122 to supply power to the heating element 12 while stably clamping the atomizing core 10.

[0043] like Figure 5 and Figure 6 As shown, the first side 111a and the second side 111b may be provided with heating elements 12 respectively.

[0044] Both the first side 111a and the second side 111b may be provided with one or more heating elements 12. As an example, the first side 111a is provided with one heating element 12, and the second side 111b is provided with one heating element 12.

[0045] By providing heating elements 12 on both the first side 111a and the second side 111b opposite to the main body 111, the heating of the main body 111 can be more uniform, which is beneficial to improving the atomization efficiency.

[0046] like Figure 6As shown, the heating element 12 may include two electrical contacts 122, and the heating element 121 is connected between the two electrical contacts 122. The two electrical contacts 122 are arranged along the first direction X.

[0047] The main body 111 also has a bottom surface opposite the top surface, and the first direction X can be the extension direction of the intersection line between the side surface where the power receiving part 122 is located and the bottom surface. For example, the extension direction of the intersection line between the first side surface 111a and the bottom surface.

[0048] Two electrical contact parts 122 are provided along the first direction X. The main body part 111 can be clamped by two clamping members 30 arranged along the first direction X, so that the base 11 can be more stably installed on the base 20.

[0049] The clamping member 30 clamps the main body 111, which restricts the movement of the main body 111 in the second direction Y, which is perpendicular to the first direction X. The second direction Y is parallel to the arrangement direction of the first side surface 111a and the second side surface 111b.

[0050] The main body 111 of the base 11 can be cuboid in shape. The first direction X can be the length direction of the main body 111, and the second direction Y can be the width direction of the main body 111. The first side surface 111a and the second side surface 111b can be two opposite sides of the main body 111 in the width direction. The top surface and the bottom surface can be two opposite surfaces of the main body 111 in the height direction. The cuboid shape of the main body 111 is not only easy to manufacture but also convenient to install.

[0051] like Figure 6 As shown, the substrate 11 may be provided with a liquid inlet channel 112a, which extends from the surface of the liquid inlet portion 112 into the main body portion 111.

[0052] The aerosol generation matrix can enter the matrix 11 through the liquid inlet channel 112a, which is beneficial for the aerosol generation matrix to wet the matrix 11.

[0053] As an example, the liquid inlet 112 may be cylindrical, with one end of the liquid inlet 112 connected to the top surface of the main body 111, and the opening of the liquid inlet channel 112a located at the other end of the liquid inlet 112.

[0054] When the columnar liquid inlet 112 is engaged with the first seal 50, it can extend to the outside of the first seal 50, that is, to the outside of the atomization chamber 1a, and contact the aerosol generating matrix, so that the aerosol generating matrix can enter the matrix 11 from the opening of the liquid inlet channel 112a at the end of the liquid inlet 112.

[0055] The substrate 11 may include one or more liquid inlets 112. For example Figure 6As shown, the base 11 may include two liquid inlet sections 112, each of which is provided with a liquid inlet channel 112a. The two liquid inlet sections 112 may be arranged at intervals along the first direction X on the top surface of the main body 111.

[0056] By setting multiple liquid inlets 112, the substrate 11 can be more fully and uniformly wetted by the aerosol generation matrix, which is beneficial to improving the atomization effect of the atomizing core 10.

[0057] An annular stop 112b may also be provided on the outer wall of the liquid inlet 112. When the liquid inlet 112 is inserted into the liquid inlet hole 50a, the annular stop 112b can abut against the first sealing member 50 to form a seal, thereby improving the sealing performance of the atomizing assembly 1.

[0058] like Figure 4 As shown, the clamping member 30 may include an electrode portion 31 and two first clamping portions 32 connected to the electrode portion 31. The two first clamping portions 32 are arranged opposite to each other and spaced apart, clamping the two first clamping portions 32 on opposite sides of the main body portion 111, and at least one first clamping portion 32 is in contact with the power receiving portion 122 to form an electrical connection. The electrode portion 31 is exposed on the side of the base 20 away from the main body portion 111.

[0059] The two first clamping parts 32 can be bent toward each other, so that the two first clamping parts 32 can clamp the atomizing core 10 more firmly.

[0060] The clamping member 30 is not only simple in structure and low in manufacturing cost, but it can also clamp various atomizing cores 10 of different sizes. The electrode part 31 and the two first clamping parts 32 form a groove-shaped structure. When the clamping member 30 clamps the atomizing core 10, the main body part 111 is inserted between the two first clamping parts 32. The two first clamping parts 32 can respectively abut against the first side 111a and the second side 111b of the main body part 111, and abut against the power receiving part 122, thereby clamping the atomizing core 10 and realizing mechanical and electrical connection with the atomizing core 10.

[0061] On the side of the base 20 away from the main body 111, the electrode part 31 is exposed on the base 20, and can form an electrical connection with the power supply 100 when the atomizer 200 is connected to the power supply 100.

[0062] The clamping member 30 can be an integral imaging structure, that is, the electrode part 31 and the two first clamping parts 32 are integrated into one unit. Exemplarily, the clamping member 30 can be formed by bending a metal sheet. For example, it can be formed by stamping.

[0063] like Figure 4As shown, the base 20 is provided with two insertion holes 20a for each clamping member 30, and two first clamping parts 32 are respectively inserted into the two insertion holes 20a. The end of the first clamping part 32 away from the electrode part 31 is located outside the insertion hole 20a and abuts against the power receiving part 122.

[0064] During assembly, simply insert the two first clamping parts 32 into the two sockets 20a respectively, so that the clamping member 30 is stably mounted on the base 20. The end of the first clamping part 32 extending out of the socket 20a is used to clamp the main body part 111 and to form an electrical connection with the power receiving part 122.

[0065] like Figure 4 As shown, the base 20 is also provided with a plurality of second clamping parts 21, which are located around the main body 111 and abut against the side of the main body 111.

[0066] With the combined clamping of the first clamping part 32 and the second clamping part 21, the main body 111 can be more stably mounted on the base 20.

[0067] The first clamping part 32 and the second clamping part 21 may be located on different sides of the main body 111. For example, the second clamping part 21 may be located on at least one of the opposite sides of the main body 111 in the first direction X, thereby restricting the movement of the main body 111 in the first direction X.

[0068] 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 surface of the base 20 away from the atomizing core 10 may also be provided with a groove 20c, and the electrode part 31 of the clamping member 30 may be located in the groove 20c to provide a limit for the electrode part 31, so as to make the clamping member 30 more securely installed.

[0069] like Figure 4 As shown, two second clamping parts 21 can be provided on the base 20, and the two second clamping parts 21 are located on opposite sides of the main body 111 in the first direction X.

[0070] As an example, the second clamping part 21 may be plate-shaped and may abut against the surface of the main body part 111.

[0071] like Figure 4 As shown, the atomizing assembly 1 may also include a second seal 40, which is located between the main body 111 and the base 20, and the clamping member 30 is disposed through the second seal 40.

[0072] The second sealing element 40 is provided between the main body 111 and the base 20 to seal the gap between the insertion hole 20a and the first clamping part 32, so as to prevent the aerosol generating matrix flowing out from the surface of the substrate 11 or the condensate formed in the atomization chamber 1a from flowing into the insertion hole 20a and leaking out of the atomization chamber 1a.

[0073] The atomizing assembly 1 may also have an air inlet 20b and an air outlet 50b. The air inlet 20b can penetrate the base 20 and the second seal 40, and can be located between the two clamping members 30, facing the bottom surface of the main body 111. The air inlet 20b communicates with the atomizing chamber 1a. The air outlet 50b can penetrate the first seal 50, and can be located between the two insertion holes 20a. The air outlet 50b communicates with the atomizing chamber 1a. Air can enter the atomizing chamber 1a through the air inlet 20b and then exit through the air outlet 50b, carrying away the aerosol in the atomizing chamber 1a.

[0074] Reference Figure 4 As shown, a protrusion 22 can also be provided on the base 20. The protrusion 22 is arranged around the air inlet 20b. The protrusion 22 can act as a blockage to prevent any liquid that may appear in the atomizing chamber 1a from leaking out through the air inlet 20b.

[0075] The bottom surface of the main body 111 may also be provided with a recessed area 111c. The recessed area 111c may be located between the two electrical connection parts 122. When the atomizing core 10 is installed on the base 20, the recessed area 111c may be directly opposite the air inlet 20b. The recessed area 111c can play a role in avoiding obstruction, allowing air to enter the atomizing chamber 1a more smoothly.

[0076] Figure 8 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application, as shown below. Figure 8 As shown, the atomizer 200 includes a liquid storage housing 201 and any of the aforementioned atomizing components 1. The liquid storage housing 201 is connected to the first sealing member 50 so that the two form a liquid storage chamber 200a, and a portion of the liquid inlet 112 is located in the liquid storage chamber 200a.

[0077] One end of the liquid storage tank housing 201 has a nozzle 202, and the other end is open for connection to the atomizing assembly 1. At least a portion of the atomizing assembly 1 is inserted into the liquid storage tank housing 201, and a first sealing member 50 abuts against the inner wall of the liquid storage tank housing 201 to form a seal. The liquid storage tank 200a is used to contain the aerosol generating matrix. The aerosol generating matrix in the liquid storage tank 200a can partially wet the atomizing core 10 through the liquid inlet 112 extending into the liquid storage tank 200a.

[0078] The atomizing chamber 1a can be connected to the mouthpiece 202. For example, the air outlet 50b on the first seal 50 is connected to the mouthpiece 202, so that the aerosol in the atomizing chamber 1a can be discharged from the mouthpiece 202.

[0079] When assembling atomizer 200, with Figure 4 Taking the atomizing component 1 as an example, the clamping member 30 can be inserted into the socket 20a first to complete the installation of the clamping member 30; then the second sealing member 40 can be installed on the base 20, and the atomizing core 10 can be installed into the base 20. The atomizing core 10 is clamped by the first clamping part 32 and the second clamping part 21; the first sealing member 50 is connected to the base 20 to form the atomizing component 1; finally, the atomizing component 1 is inserted into the liquid storage tank housing 201 to form the atomizer 200.

[0080] The atomizing component 1 has a simple structure and is easy to assemble. By applying the aforementioned atomizing component 1 to the atomizer 200, the assembly of the atomizer 200 can be facilitated, which helps to reduce the production cost of the atomizer 200.

[0081] Figure 9 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application. Figure 2 An aerosol generating device refers to a device that heats an aerosol generating matrix to a certain temperature, causing the corresponding components in the matrix to atomize and form inhalable aerosols. Inhalation refers to the process of inhaling the aerosol into the user's mouth, nasal cavity, or lungs through the mouth or nose. An aerosol generating matrix refers to a product capable of forming aerosols when heated. Aerosols may contain volatile compounds. The aerosol generating matrix can be liquid or semi-liquid.

[0082] like Figure 9 As shown, the aerosol generating device includes an atomizer 200 and a power supply 100. The atomizer 200 can be... Figure 8 The atomizer 200 is shown.

[0083] The power supply 100 can be detachably connected to the atomizer 200. For example, the power supply 100 can be provided with a slot 100a, into which the atomizer 200 can be inserted.

[0084] An electrical connector 101 may be provided at the bottom of the slot 100a of the power supply 100. The atomizer 200 is inserted into the slot 100a, and the electrical connector 101 may contact the electrode part 31 of the clamping member 30 to form an electrical connection. Figure 9 To facilitate the display of the electrical connector 101, part of the sidewall of the slot 100a is omitted.

[0085] For example, electrical connector 101 may include conductive posts.

[0086] As an example, the conductive post can be a pogo pin. When the atomizer 200 is connected to the power supply 100, the pogo pin is compressed and comes into contact with the electrode portion 31. The spring force of the pogo pin ensures good contact between the pogo pin and the electrode portion 31, reducing the risk of poor contact.

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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
