This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] The first embodiment of this application provides an atomizing device that utilizes the principle of heating without combustion to heat an atomizing matrix to generate an aerosol for user use.

[0037] It should be noted that the term "aerosol" in this context refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used herein can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0038] As used herein, the term "atomizing matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable atomizing matrices are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono, di, or triacetic acid esters of glycerol; and aliphatic esters of mono, di, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Atomizing matrices may include nicotine. Atomizing matrices may include water. Atomizing matrices may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Atomizing matrices may include propylene glycol. Atomizing matrices may include plant-based materials. Atomizing matrices may include homogeneous plant substrates. Homogeneous plant substrates may contain volatile compounds. These compounds may be released from the atomizing matrix upon heating. Atomizing matrices are liquid and may be stored directly in a container or via a storage medium (e.g., reservoir cotton).

[0039] Please see Figures 1 to 11 The atomizing device includes an atomizer 1 and a power supply component 2. The power supply component 2 is used to supply power to the atomizer 1. The power supply component 2 includes a control circuit board (not shown in the figure) and a battery 21. The control circuit board and the battery 21 are electrically connected. The battery 21 provides the power required for the atomizer 1 to work. The control circuit board 21 can control the working power of the atomizer 1.

[0040] In some embodiments, the atomizing device further includes a housing 3, which is disposed outside the atomizer 1 and the power supply component 2, assembling the atomizer 1 and the power supply component 2 into an integrated structure. The housing 3 facilitates the overall carrying and transportation of the atomizing device and also provides protection for the atomizer 1 and the power supply component 2.

[0041] Please see Figure 2The atomizer 1 includes a housing assembly 11 and an atomizing core 12. The housing assembly 11 has a liquid storage chamber 13, an air outlet channel 14, and a mounting chamber 15. The mounting chamber 15 and the liquid storage chamber 13 are arranged along a first direction Y. The two ends of the mounting chamber 15 along a second direction X are connected to the liquid storage chamber 13. The atomizing core 12 is arranged in the mounting chamber 15 along the second direction X and can communicate with the liquid storage chamber 13. The air outlet channel 14 is arranged inside the liquid storage chamber 13 and is connected to both the mounting chamber 15 and the outside of the atomizer 1. The liquid storage chamber 13 is used to store the atomizing matrix. When the atomizing device is working, the atomizing matrix flows from the liquid storage chamber 13 into the atomizing core 12, is heated to generate an aerosol, and then the aerosol is discharged to the outside of the atomizer 1 along the air outlet channel 14.

[0042] Please see Figures 2 to 4 In some embodiments, the housing assembly 11 includes a housing body 111 and a base 112, which together form a liquid storage chamber 13 and an air outlet channel 14. A mounting cavity 15 is formed on the base 112, which is also provided with a liquid inlet channel 113 and a mounting channel 114. The liquid inlet channel 113 communicates with the liquid storage chamber 13 and is also connected to the mounting cavity 15 through the mounting channel 114. Both ends of the atomizing core 12 are installed in the mounting channel 114 and are connected to the liquid storage chamber 13 through the liquid inlet channel 113. The base 112 is also provided with an air outlet 115 on the side facing the air outlet channel 14. The air outlet 115 is used to connect the air outlet channel 14 and the mounting cavity 15 and to guide the generated aerosol to be discharged sequentially along the mounting cavity 15, the air outlet 115 and the air outlet channel 14 to the outside of the atomizer 1.

[0043] In some embodiments, the liquid storage chamber 13 and the mounting chamber 15 are arranged along the first direction Y, and the axis of the liquid inlet channel 113 is a straight line along the first direction Y. This helps the atomizing matrix in the liquid storage chamber 13 to flow to the atomizing core 12 along the liquid inlet channel 113 under the action of gravity, reducing the resistance to the flow of the atomizing matrix, thereby helping to ensure the sufficiency of the atomizing matrix and accelerate the aerosol generation rate.

[0044] Please continue reading. Figure 3 In some embodiments, the base 112 is further provided with an air inlet 116 on the side away from the air outlet channel 14. The air inlet 116 communicates with the mounting cavity 15 and is used to guide outside air into the mounting cavity 15 through the air inlet 116. The air inlet 116 and the air outlet 115 are arranged opposite each other on both sides of the mounting cavity 15 along the first direction Y. The air inlet 116 is used to guide outside air into the mounting cavity 15, and the air outlet 115 is used to guide the aerosol in the mounting cavity 15 to be discharged, forming an airflow area, and the airflow flows as... Figure 3 As shown, this effectively ensures the normal operation of the atomizing equipment.

[0045] In some embodiments, both the air outlet 115 and the air inlet 116 are located at the center of the atomizing core 12, and the mounting channel 114 extends along the second direction X, allowing the atomizing matrix to move from both ends to the center within the atomizing core 12 along the second direction X. The flow diagram of the atomizing matrix is ​​shown below. Figure 4 As shown, the positions of the airflow areas formed by the air outlet 115 and the air inlet 116 correspond to each other, which can effectively ensure sufficient airflow and avoid the atomizing core 12 from having a burnt taste due to high temperature caused by insufficient airflow, thus affecting the taste of the aerosol and helping to improve the user experience.

[0046] Please see Figures 5 to 7 In some embodiments, the base 112 includes an upper seal 1121, a lower seal 1122, and a bottom cover 1123. The upper seal 1121, the lower seal 1122, and the bottom cover 1123 are arranged sequentially along the first direction Y. The upper seal 1121 and the housing body 111 enclose a liquid storage cavity 13, which is located between the liquid storage cavity 13 and the lower seal 1122 to prevent the atomized matrix from leaking directly into the mounting cavity 15 and from leaking from the air outlet 115 or the air inlet 116. The lower seal 1122 is provided with a mounting cavity 15 and a mounting channel 114. The liquid inlet channel 113 penetrates the upper seal 1121 along the first direction Y and extends into the lower seal 1122, communicating with the mounting channel 114 and the mounting cavity 15. The air outlet 115 penetrates the upper seal 1121 along the first direction Y and communicates with the mounting cavity 15. The air inlet 116 penetrates the base 112 along the first direction Y and extends into the lower seal 1122, communicating with the mounting cavity 15. Both the upper seal 1121 and the lower seal 1122 can be made of silicone material, providing a good sealing effect and preventing leakage of the atomizing matrix. The bottom cover 1123 can be made of silicone material or, like the body 111, of injection-molded material. The bottom cover 1123 has an electrode hole 117 for inserting and installing the electrode post 16. The electrode post 16 is either in contact with or plugged into the power supply component 2, facilitating the connection between the atomizer 1 and the power supply component 2. The electrode post 16, as the structure for electrically connecting the power supply component 2 and the atomizer 1, reduces the need for wiring and allows for easy plug-in connection between the atomizer 1 and the power supply component 2, ensuring connection stability while improving assembly and disassembly efficiency.

[0047] In some embodiments, in order to achieve a stable connection between the atomizer 1 and the power supply component 2, the atomizer 1 and the power supply component 2 may be provided with a magnetic connection structure, a plug-in connection structure, or a threaded connection structure, etc.

[0048] Please see Figure 9 and Figure 10The atomizing core 12 includes a liquid guide 121 and a heating element 122. The liquid guide 121 is used to conduct the atomizing matrix. Both ends of the liquid guide 121 are connected to the liquid storage chamber 13. The liquid guide 121 includes a liquid guide middle portion 1211 and two liquid guide ends 1212. The liquid guide middle portion 1211 is disposed between the two liquid guide ends 1212 along the axial direction of the liquid guide 121 (the second direction X mentioned above). The outer diameter of the end of the liquid guide 1212 connected to the liquid guide middle portion 1211 gradually decreases in the direction away from the liquid guide middle portion 1211, so that the liquid guide middle portion 1211 is radially ( Figure 10 The direction perpendicular to the second direction X is radial) protrudes outward relative to the liquid guiding end 1212. The heating element 122 is used to heat the atomized matrix to generate aerosol after being energized. The heating element 122 is covered on the outer surface of the liquid guiding 121. The liquid guiding end 1212 is located in the installation channel 114, and the liquid guiding middle part 1211 is located in the installation cavity 15, thereby generating aerosol in the installation cavity 15. The airflow area formed by the air inlet 116 and the air outlet 115 covers the liquid guiding middle part 1211, which can quickly carry the aerosol out and remove the heat of the liquid guiding middle part 1211.

[0049] In some embodiments, the liquid guide 121 can be a liquid guide tube or a liquid guide rod.

[0050] Please see Figure 11 The heating element 122 includes a first connecting sleeve 1221, a second connecting sleeve 1222, and a plurality of heating wires 1223. The plurality of heating wires 1223 are disposed between the first connecting sleeve 1221 and the second connecting sleeve 1222, and are spaced apart circumferentially from the first connecting sleeve 1221 and the second connecting sleeve 1222. The outer diameters of the first connecting sleeve 1221 and the second connecting sleeve 1222 gradually decrease in the direction away from the heating wires 1223. The heating wires 1223 constitute the heating area. The first connecting sleeve 1221 and the second connecting sleeve 1222 are used to realize the parallel connection of the plurality of heating wires 1223 and to realize the electrical connection between the heating wires 1223 and the power supply component 2.

[0051] Because the outer diameter of the end of the liquid-conducting end 1212 connected to the middle part of the liquid-conducting part 1211 gradually decreases in the direction away from the middle part of the liquid-conducting part 1211, the middle part of the liquid-conducting part 1211 is arranged to protrude outward relative to the end of the liquid-conducting end 1212 along the radial direction of the liquid-conducting part 121. The first connecting sleeve 1221 and the second connecting sleeve 1222 are sleeved on the outer surface of the end of the liquid-conducting end 1212. The heating wire 1223 is arranged on the outer surface of the middle part of the liquid-conducting part 1211. The outer diameters of the first connecting sleeve 1221 and the second connecting sleeve 1222 both gradually decrease in the direction away from the heating wire 1223, so that the outer diameter of the heating area where the heating wire 1223 is located is relatively large, thereby increasing the outer surface of the heating area. This can increase the number of heating wires 1223 and the extension length of a single heating wire 1223, thereby helping to increase the heating area and heating power of the heating area. Meanwhile, compared with traditional atomizing devices, this application improves the outer diameter (or the size in the first direction Y) of the heating area without changing its size in the second direction X. This makes the heating area match the airflow area range formed by the air outlet 115 and the air inlet 116 in traditional atomizing devices. There is no situation where the airflow area is smaller than the heating area (size in the second direction X), causing the heating area temperature to be too high and produce a burnt taste, thus effectively ensuring the taste of the aerosol.

[0052] In some embodiments, the heating wire 1223 may also be an arc-shaped structure, that is, the heating wire 1223 is divided into multiple heating points, and the distance from each heating point to the central axis of the heating body 122 is different. For example, the distance from the heating point to the central axis of the heating body 122 gradually increases from both ends to the middle, which can further increase the heating area of ​​the heating region.

[0053] In some embodiments, the heating wire 1223 can be a straight structure extending along its length direction. In order to further increase the heating area, the heating wire 1223 can also be a zigzag structure or a wavy structure.

[0054] In some embodiments, the liquid guide 121 is made of a porous material, which can utilize the wicking effect to conduct the atomizing matrix. For example, the liquid guide 121 is made of a porous ceramic material, which has a certain hardness to facilitate shape fixation, so as to support the heating element 122 to form a shape-stable atomizing core 12, thereby closely matching the base 112 and avoiding leakage caused by shape changes.

[0055] In some embodiments, the first connecting sleeve 1221, the second connecting sleeve 1222, and the heating wire 1222 in the heating element 122 are made of a metal resistive material, which can generate heat after being energized, and the first connecting sleeve 1221, the second connecting sleeve 1222, and the heating wire 1222 are integrally formed. Of course, in other embodiments, the first connecting sleeve 1221, the second connecting sleeve 1222, and the heating wire 1222 can also be made of a conductive ceramic material without micropores.

[0056] In some embodiments, the density of the liquid-conducting middle portion 1211 is less than the density of the liquid-conducting end portion 1212, thereby increasing the liquid-conducting effect of the liquid-conducting middle portion 1211 and helping to accelerate the aerosol generation rate.

[0057] In some embodiments, on the axial (axial direction) cross section of the heating element 122, the projection of the heating wire 1223 forms an angle with the axis of the heating element 122, that is, the heating wire 1223 is inclined relative to the axial (second direction X) of the liquid guide 121, and multiple heating wires 1223 are inclined in the same direction, thereby increasing the length of a single heating wire 1223 to increase the heating power of the atomizing device.

[0058] In some embodiments, multiple heating wires 1223 are arranged at equal intervals to ensure uniform heating in the heating area, thereby ensuring uniform aerosol generation and avoiding the occurrence of core clogging.

[0059] Please continue reading. Figure 11 In some embodiments, the heating element 122 further includes a first mounting sleeve 1224 and a second mounting sleeve 1225. The first mounting sleeve 1224 and the second mounting sleeve 1225 are also sleeved on the outer surface of the liquid-conducting end 1212. The first mounting sleeve 1224 is located at the end of the first connecting sleeve 1221 away from the heating wire 1223, and the second mounting sleeve 1225 is located at the end of the second connecting sleeve 1222 away from the heating wire 1223. The first mounting sleeve 1224 and the second mounting sleeve 1225 are disposed within the mounting channel 114 and are made of metal. Due to the smooth surface of the metal material, the first mounting sleeve 1224 and the second mounting sleeve 1225 can be better installed within the mounting channel 114, achieving a better sealing effect. The first mounting sleeve 1224, the first connecting sleeve 1221, the heating wire 1223, the second connecting sleeve 1222, and the second mounting sleeve 1225 are continuously arranged along the second direction X, and the first mounting sleeve 1224, the first connecting sleeve 1221, the heating wire 1223, the second connecting sleeve 1222, and the second mounting sleeve 1225 are made of the same metal resistive material, that is, they can be integrally formed to constitute the heating element 122. Of course, the heating element 122 can also be a split structure, with the first connecting sleeve 1221, the heating wire 1223, and the second connecting sleeve 1222 serving as the main structure for heating by electricity and made of a metal resistive material with good heating effect, and the first mounting sleeve 1224 and the second mounting sleeve 1225 made of a low-cost and easy-to-process metal material.

[0060] In some embodiments, the outer diameters of the first mounting sleeve 1224 and the second mounting sleeve 1225 are the same as the minimum outer diameters of the first connecting sleeve 1221 and the second connecting sleeve 1222.

[0061] In some embodiments, a first connecting sleeve 1221 is provided with a first lead 1226, and a second connecting sleeve 1222 is provided with a second lead 1227. The first lead 1226 and the second lead 1227 are used for electrical connection with the power supply component 2. The first lead 1226 and the second lead 1227 serve as the positive and negative electrodes of the heating element 122, respectively, and are passed through the base 112 and electrically connected to the electrode post 16 to realize the electrical connection between the atomizer 1 and the power supply component 2.
