Please refer to Figure 2 , a mouthpiece 221 is formed on one side of the liquid storage chamber 20 facing away from the support base 30.

[0094] Please refer to Figure 3 , which shows that the atomization component 10 is arranged inside the liquid storage chamber 20. Please refer to Figure 2 , an assembly hole 38 is provided on the support base 30, and the atomization component 10 can be inserted into the support base 30 through the assembly hole 38.

Please refer to Figure 3 , which shows the placement cavity 90. When the atomization component 10 is in a working state, the atomization component 10 can heat the aerosol matrix infiltrating into the atomization component 10 to make it evaporate. When the user inhales through the mouthpiece 221 of the liquid storage chamber 20, there is an air flow inside the atomization component 10, and the evaporated aerosol matrix forms a mist under the action of the air flow condensation, and the mist can flow towards the mouthpiece 221 along with the air flow.

[0095] Please refer to Figure 2 and Figure 3 , a liquid injection hole 32 communicating with the placement cavity 90 is provided on the support base 30, and a plug body 70 is arranged in the liquid injection hole 32.

One end of the nozzle part 22 extends into the liquid storage chamber main body 21 and the two are connected. A nozzle opening 221 is formed at one end of the nozzle part 22 located outside the liquid storage chamber main body 21. One end of the protective sleeve 40 extends into the nozzle part 22, and the protective sleeve 40 is in sealing cooperation with the nozzle part 22.

[0100] In one example, please refer to Figure 3 , a nozzle sleeve 80 is sleeved outside the nozzle part 22 to improve the aesthetics.

[0101] Please refer to Figures 4 - 5 , Figure 4 is a schematic structural diagram of the atomization assembly 10 provided by the embodiment of the present application, Figure 5 is a cross-sectional view schematic diagram of the atomization core 11 provided by the implementation of the present application.

[0102] The atomization assembly 10 provided by the embodiment of the present application includes an atomization core 11, and the atomization core 11 includes a heating element 111, a cotton wrapping layer and a support member.

[0103] Please refer to Figure 5 , the heating element 111 is located inside the atomization assembly 10, and a first pin 112 and a second pin 113 are arranged on the heating element 111. When an electric current passes through the heating element 111, the heating element 111 can generate heat, and then can heat the aerosol matrix infiltrating into the atomization core 11.

[0104] The cotton wrapping layer is cylindrical, and there is one or more cotton wrapping layers sleeved outside the heating element 111 along the radial direction of the atomization assembly 10. For example, in one example, the number of cotton wrapping layers is one, and the heating element 111 is arranged on the inner side surface of the cotton wrapping layer; or, in other examples, the number of cotton wrapping layers is two or more, and the cotton wrapping layers are sequentially sleeved along the radial direction of the atomization assembly 10. In a specific example, there are two cotton wrapping layers, which are an inner cotton wrapping 114 and an outer cotton wrapping 116 respectively. Please refer to Figure 5 , which shows the inner cotton wrapping 114 and the outer cotton wrapping 116.

[0105] In one example, please refer to Figure 5, the thickness of the outer wrapping cotton 116 in the radial direction is less than the thickness of the inner wrapping cotton 114 in the radial direction.

[0106] In the embodiments of the present application, there is one or more support members, and the support members are sleeved on the outer side of the corresponding wrapping cotton layer. When there is one support member, the support member is the outermost layer of the atomizing core 11.

[0107] In one example, the number of support members is consistent with the number of wrapping cotton layers, and the support members are sleeved on the outer side of the corresponding wrapping cotton layer. For example, there are two support members, namely the inner support 115 and the outer cover 117. The inner support 115 is sleeved on the outer side of the inner wrapping cotton 114, and the outer cover 117 is sleeved on the outer side of the outer wrapping cotton 116. That is, the inner wrapping cotton 114, the inner support 115, the outer wrapping cotton 116, and the outer cover 117 are sleeved in sequence from the inside to the outside, and the heating element 111 is arranged on the inner side surface of the inner wrapping cotton 114.

[0108] Please refer to Figure 5 , an outer cover opening 1171 is arranged on the circumferential side surface of the outer cover 117, and an inner support opening 1151 is arranged on the circumferential side surface of the inner support 115. The aerosol matrix in the placement cavity can penetrate into the outer wrapping cotton 116 through the outer cover opening 1171. The aerosol matrix on the outer wrapping cotton 116 can penetrate into the inner wrapping cotton 114 through the inner support opening 1151. The aerosol matrix penetrating into the inner side surface of the inner wrapping cotton 114 can come into contact with the heating element 111.

[0109] In one example, please refer to Figure 5 , the outer cover 117 includes a first straight cylinder section 1172, an intermediate connection section 1173, and a second straight cylinder section 1174. The first straight cylinder section 1172, the intermediate connection section 1173, and the second straight cylinder section 1174 are connected in sequence. The diameter of the first straight cylinder section 1172 is greater than the diameter of the second straight cylinder section 1174. The inner wrapping cotton 114, the inner support 115, and the outer wrapping cotton 116 are arranged inside the first straight cylinder section 1172.

[0110] In one example, one end of the outer cover 117 is inserted into the support base 30.

[0111] In the embodiments of the present application, the material of the support member is a corrosion-resistant material to prevent the support member from chemically reacting with the aerosol matrix. That is, when the atomizing core 11 includes more than two support members, each support member is a corrosion-resistant material. For example, when there are two support members, namely the inner support 115 and the outer cover 117, the materials of the inner support 115 and the outer cover 117 are both corrosion-resistant materials.

[0112] It should be noted that the corrosion-resistant material mentioned in the embodiments of the present application refers to a material that does not chemically react with the aerosol matrix or is difficult to chemically react with the aerosol matrix.

[0113] In the existing atomization components, the atomization core outer cover and the inner support are made of brass, and the outer peripheral surfaces of the atomization core outer cover and the inner support are electroplated with a protective layer. However, there are usually micropores in the protective layer, and the aerosol matrix penetrates through the micropores and reacts chemically with the brass, so that the aerosol of the atomization device contains heavy metal substances.

[0114] In the embodiment of the present application, by setting the material of the support member in the atomization core 11 to a corrosion-resistant material that can prevent chemical reaction with the aerosol matrix, it is possible to avoid as much as possible that the aerosol generated by the atomization component contains heavy metal substances, and to avoid that the heavy metal substances in the aerosol affect the taste of the aerosol, thereby improving the safety when using the atomizer.

[0115] In one embodiment, the material of the support member is stainless steel, and a passivation layer is formed on the outer surface of the support member.

[0116] That is, in the embodiment of the present application, the material of the support member is corrosion-resistant stainless steel, which refers to stainless steel with good resistance in various corrosive environments. In addition, by performing passivation treatment on the support member, a passivation layer can be formed on its surface. Among them, the passivation treatment of stainless steel is a process of forming a dense and stable passivation film on the surface of stainless steel through chemical reaction, which can improve the corrosion resistance, wear resistance and other properties of stainless steel.

[0117] It should be noted that when there are two support members and the two support members are the inner support 115 and the outer cover 117 respectively, the materials of the inner support 115 and the outer cover 117 are both corrosion-resistant stainless steel materials and passivation layers are formed on the outer surfaces.

[0119] In one example, the outer cover 117 and the inner support 115 are formed by die stamping, that is, the outer cover 117 and the inner support 115 are stamped parts. Among them, die stamping is a common metal processing technology. By using a die and a stamping device, pressure is applied to the metal sheet to make it plastically deformed, so as to obtain parts with the required shape and size.

[0120] In the embodiment of the present application, by setting the material of the support member to stainless steel and forming a passivation layer on the outer surface of the support member, while preventing the chemical reaction between the support member and the aerosol matrix, it is beneficial to reduce the cost of the atomization component 10; in addition, when the outer cover 117 and the inner support 115 are formed by die stamping, the forming efficiency is high, and the surface quality and dimensional accuracy of the parts are good.

[0187] In the embodiment of the present application, since the atomization assembly 10 can be sleeved inside the protective sleeve 40 and the protective sleeve 40 is fixedly connected to the support base 30 along the circumferential direction, the protective sleeve 40 isolates the aerosol matrix inside the atomizer 100 from the atomization assembly 10, thereby preventing the aerosol matrix from entering the atomization assembly 10 when the atomizer 100 is in an unused state (such as during transportation or sale); in the embodiment of the present application, an easily breakable part is formed on the protective sleeve 40, and since the connection strength of the easily breakable part is less than the connection strength between the connecting rod 50 and the protective sleeve 40, when a force is applied to the connecting rod 50 in a direction away from the support base 30, the protective sleeve 40 can be broken at the easily breakable part, and the broken protective sleeve 40 can be moved to the target position. At this time, the aerosol matrix can penetrate into the atomization assembly 10.

[0188] In one embodiment, please refer to Figure 19 , the protective sleeve 40 includes a first sleeve body 41, a second sleeve body 42, and a connecting sleeve 43.
