[0048] The present application is based on the technical problems of slow heat dissipation and uneven temperature in cup-shaped atomizers, and provides an atomizer and an aerosol generating device. The atomizer includes a cup body and a heating element. When the heating element is connected to the circuit, heat is generated. Since the cup body is made of metal and the heating element fits the cup body, the heat generated by the heating element is directly and quickly conducted to the cup body, causing the cup body to heat up quickly, thereby achieving boiling of the aerosol generating matrix in the cup body and generating aerosol vapor for user use. Compared with existing cup-shaped atomizers such as ceramic atomizer cups and glass atomizer cups, the combined structure of the metal cup body and the heating element can quickly conduct heat, and the temperature distribution uniformity of the cup body is good, thereby achieving rapid heating and atomization to generate aerosol, and significantly improving the atomization efficiency. For details, please refer to the following embodiments.

[0049] One embodiment of the present application provides an aerosol generating device including an atomizer 10. The atomizer 10 is used to heat an aerosol generating substrate to generate aerosol by atomization for inhalation by a user.

[0050] Please refer to Figure 1 and Figure 2The atomizer 10 includes a cup body 11 and a heating element 12. The cup body 11 is cup-shaped and made of metal. The top of the cup body 11 is open and is used to accommodate an aerosol-generating substrate. Before use, the user can drop the aerosol-generating substrate into the cup body 11 through the opening. The heating element 12 is arranged to fit the outer periphery of the cup body 11; the heating element 12 adopts electric heating, and when the bottom pin 122 of the heating element 12 is connected to the circuit, heat is generated. Since the cup body 11 is made of metal and the heating element 12 fits the cup body 11, the heat generated by the heating element 12 is directly conducted to the cup body 11, so that the cup body 11 quickly heats up, and the aerosol generating matrix in the cup body 11 is heated; when the heating element 12 continues to heat, the heat is continuously conducted to the cup body 11, and the temperature of the cup body 11 increases, so that the aerosol generating matrix in the cup body 11 gradually boils and generates aerosol vapor; compared with the existing cup-shaped atomizer 10 such as the ceramic atomization cup and the glass atomization cup, the combination structure of the metal cup body 11 and the heating element 12 can quickly conduct heat, and the temperature distribution uniformity of the cup body 11 is good, so that rapid heating and atomization can be achieved to generate aerosol, which significantly improves the atomization efficiency. The cup body 11 can be made of stainless steel, which has good thermal conductivity, high heating efficiency, good structural strength, is not easily corroded or rusted, and has good durability. The cup body 11 made of stainless steel has a relatively high thermal conductivity of about 15-20W / m·K; while the thermal conductivity of glass is relatively low, about 0.9W / m·K; the thermal conductivity of ceramic material is also relatively low, about 1-2W / m·K; therefore, compared with existing ceramic atomizer cups and glass atomizer cups, the atomizer 10 provided in this application has the advantages of good thermal conductivity and fast heat dissipation speed. Through heat convection and heat radiation, the entire cup body 11 will reach the same temperature value, so that the temperature of the entire cup body 11 is balanced, and the aerosol vapor produced has a better taste experience. The material strength of the stainless steel cup body 11 is several times higher than that of the atomizer cups made of ceramic and glass materials, which ensures the structural strength of the atomizer 10.

[0051] Please refer to Figure 1 、 Figure 2 and Figure 3Furthermore, the cup body 11 includes a tube body 111 and a bottom cover 112. The tube body 111 is open at both ends, and the bottom cover 112 is connected to the tube body 111; the bottom cover 112 closes the opening at one end of the tube body 111 to form a cup body 11 with only one end open, which is convenient for accommodating the aerosol generating substrate. The tube body 111 can be made of a stainless steel tube, and the specific material of the stainless steel tube can be SUS 444. The tube body 111 is made by cutting or laser cutting. The process is mature, suitable for mass production, and conducive to cost saving; the stainless steel tube is processed to a limited height, and the wall thickness is selected to be 0.2mm, and the heat conduction speed is fast; the outer periphery of the tube body 111 is fitted with a heating element 12, and the heating element 12 can be formed on the outer periphery of the tube body 111 by a thick film printing process; during production, the tube body 111 is first fixed on a roller, and the printing steps are as follows: place the tube body 111 → print the insulating layer → print the pin 122 pad 121 area → print the heating element 12 slurry (thick film printing) → print the protective layer → bake and cure → weld the pin 122 → detect the resistance value; the heating element 12 can also be formed on the outer periphery of the tube body 111 by coating, 3D printing, etc. The bottom cover 112 can be made of stainless steel material with specification SUS 316L, which has good thermal conductivity and prevents heat accumulation. When the local temperature is too high, it will cause the aerosol generating matrix to explode. After the bottom cover 112 is processed and formed by a CNC lathe, it is riveted to press the bottom cover 112 into the opening at one end of the tube body 111 to form an interference fit, thereby completing the production of the cup body 11. The interference fit between the bottom cover 112 and the tube body 111 has the advantages of being conducive to heat conduction, simple assembly method, and preventing oil explosion and flying oil. Because the bottom cover 112 and the tube body 111 are riveted together, surface-to-surface contact is formed, which increases the contact area of ​​the two parts and is more conducive to heat conduction. The cup body 11 is composed of the tube body 111 and the bottom cover 112, and is easy to process and has a simple structure. Compared with the existing ceramic atomizer cup and glass atomizer cup that are sintered and formed, the heating wire is oxidized during the sintering process, making the pin 122 difficult to weld. The cup body 11 in the atomizer 10 provided in the present application does not need to be sintered and formed, so the heating element 12 will not be sintered and oxidized, and is easy to weld.

[0052] Please refer to Figure 4 and Figure 5In one embodiment, the atomizer 10 further includes a mounting structure 13 and a mouthpiece 14. The mounting structure 13 is used to mount the cup body 11. The top end of the mounting structure 13 is opened. The cup body 11 is located in the mounting structure 13, and the opening of the cup body 11 faces the opening of the mounting structure 13, so that the aerosol flows out from the opening of the cup body 11 and flows through the opening of the mounting structure 13; the mouthpiece 14 is provided for the user to inhale; the mouthpiece 14 is mounted at the opening of the mounting structure 13, and an airway hole 141 is provided axially through the mouthpiece 14. The airway hole 141 is connected to the opening of the mounting structure 13, so that the aerosol can flow out of the mouthpiece 14 through the airway hole 141 for the user to use; an airflow channel 15 is provided at the connection position between the mouthpiece 14 and the mounting structure 13, and one end of the airflow channel 15 is connected to the opening of the cup body 11 and the airflow hole 141. The other end of the airflow channel 15 is connected to the outside of the atomizer 10, so that the outside air can flow into the atomizer 10 through the airflow channel 15, mix with the aerosol flowing out of the cup body 11, and after mixing, flow out of the mouthpiece 14 through the airway hole 141; when the user inhales through the mouthpiece 14, an upward suction force is formed in the airway hole 141, so that the outside air enters the airway hole 141 from the airflow channel 15, and at the same time, the aerosol generated by heating and atomization in the cup body 11 flows upward, and the colder air outside merges with the aerosol vapor, and part of the vapor mixes with the cold air and cools down to form fine droplets, and finally the mixed gas of air, droplets and aerosol vapor is sucked out from the airway hole 141 by the user for use. The mounting structure 13 and the mouthpiece 14 can be made of high-temperature resistant plastic material to avoid being melted and damaged when the cup body 11 is heated. Specifically, the mouthpiece can be made of high-performance engineering plastic PEEK (polyetheretherketone).

[0053] Please continue to refer to Figure 4 and Figure 5In another embodiment, the air flow channel 15 includes a first channel 151, a second channel 152 and a third channel 153 that are connected in sequence for external air to flow through. The mouthpiece 14 includes a duct portion 142 and a connecting portion 143. The duct portion 142 forms an airway hole 141 for the aerosol to flow to the user; the bottom end of the duct portion 142 is inserted into the opening of the mounting structure 13, and the outer periphery of the bottom end of the duct portion 142 and the inner wall of the mounting structure 13 form a first channel 151. The first channel 151 allows external air to flow into the airway hole 141, merge with the aerosol, and then flow out of the atomizer 10; the connecting portion 143 protrudes from the outer periphery of the duct portion 142 and extends toward the bottom end of the duct portion 142, so that the connecting portion 143 is in the shape of a cover and is sleeved on the outer periphery of the top end of the mounting structure 13, so that the mouthpiece 14 is connected and fixed to the mounting structure 13. Among them, the second channel 152 is opened on the outer periphery of the top of the mounting structure 13, and the third channel 153 is opened on the outer periphery of the connecting portion 143. The second channel 152 and the third channel 153 are correspondingly arranged so that after the connecting portion 143 is installed on the mounting structure 13, the second channel 152 and the third channel 153 can be connected; the third channel 153 can adopt a window structure and be opened on the outer periphery of the connecting portion 143; when the user inhales the mouthpiece 14, the external air flow enters the airway hole 141 from the outside of the atomizer 10, and in the process, it will flow through the third channel 153, the second channel 152 and the first channel 151 in sequence. Since the bottom end of the conduit portion 142 After being inserted into the mounting structure 13, the first channel 151 is formed with the mounting structure 13. The air flow passes through the third channel 153 and the second channel 152 and then flows downward along the first channel 151. The aerosol vapor evaporated in the cup body 11 flows upward. The cold air flow meets the aerosol vapor, and the aerosol vapor is liquefied into a white mist. It is then inhaled into the user's mouth through the airway hole 141, achieving the effect of inhaling smoke, and the amount of smoke appears fuller. At the same time, after the cold air flow merges with the high-temperature aerosol vapor, it can dilute and cool the aerosol vapor, ultimately reducing the temperature of the airflow entering the user's mouth and improving the inhalation experience. The connecting portion 143 is rotatable relative to the mounting structure 13, allowing the user to rotate the mouthpiece 14. When the connecting portion 143 rotates relative to the mounting structure 13, the size of the area connected to the second channel 152 and the third channel 153 changes, that is, the size of the air intake channel changes, so that the inhaled airflow intensity varies, meeting the different tastes required by the user.The air flow channel 15 is not limited to one side of the suction nozzle 14, and a symmetrical distribution structure can be adopted, such as: the entire outer periphery of the bottom end of the duct portion 142 is separated from the inner wall of the mounting structure 13 to form a first annular channel 151; the second channel 152 is symmetrically distributed on both sides of the outer periphery of the top end of the mounting structure 13; the third channel 153 is symmetrically distributed on both sides of the outer periphery of the connecting portion 143; the above arrangement can realize convection air intake on both sides and optimize the airflow structure, which can not only adjust the size of the intake airflow to provide consumers with more experience; but also can better bring out the aerosol vapor atomized from the cup body 11, making the inhaled gas fuller.

[0054] Please continue to refer to Figure 4 and Figure 5 The mounting structure 13 includes a heat-insulating component 131 and a fixing component 132. The heat-insulating component 131 has a heat-insulating cavity 1311 for mounting the cup body 11 and has the function of insulating the cup body 11 from the outside, thereby improving the user's comfort; the top end of the heat-insulating cavity 1311 is opened, the cup body 11 is located in the heat-insulating cavity 1311, and the opening of the cup body 11 faces the opening of the heat-insulating cavity 1311, so that the aerosol vapor evaporated from the cup body 11 can flow out from the opening of the heat-insulating cavity 1311; the fixing component 132 is mounted on the top end of the heat-insulating component 131, and is used to mount the fixed suction nozzle 14; the fixing component 132 is axially penetrated. A mounting hole 1321 is provided through the mounting hole 1321, which is connected to the opening of the insulation cavity 1311 to facilitate the flow of aerosol vapor into the mounting hole 1321; the bottom end of the conduit portion 142 is inserted into the mounting hole 1321, and forms a first channel 151 with the inner wall of the mounting hole 1321, so that the external air flow can flow downward along the bottom end of the conduit portion 142 and merge with the aerosol vapor flowing out of the opening of the insulation cavity 1311; the second channel 152 is located on the outer periphery of the top end of the fixing component 132 for the external air flow to flow into the mounting hole 1321.

[0055] Please refer to Figure 5 、 Figure 6 and Figure 7Furthermore, the heat insulation component 131 includes a heat insulation cover 1312, a heat insulation sleeve 1313 and a heat insulation seat 1314.

The thermal insulation sleeve 1313 is located at the first opening 13121. The thermal insulation sleeve 1313 is annular and is installed at the top of the cup body 11 to separate the cup body 11 and the thermal insulation cover 1312, thereby preventing the heat of the cup body 11 from being transferred to the thermal insulation cover 1312 and reducing heat loss. The thermal insulation sleeve 1313 can be made of environmentally friendly silicone material, has sealing properties, and can play a temperature buffering effect, thereby preventing the high temperature of the cup body 11 from causing the thermal insulation cover 1312 and the fixing component 132 to be scalded. The opening of the cup body 11 communicates with the first opening 13121, allowing aerosol vapor to flow out of the first opening 13121 for inhalation by the user. The second opening 13122 can be larger than the cup body 11 to facilitate insertion of the cup body 11 into the insulation cavity 1311. The insulation seat 1314 seals the second opening 13122, and the bottom end of the cup body 11 is mounted on the insulation seat 1314, securing the cup body 11 within the insulation cavity 1311. The insulation seat 1314 can be made of environmentally friendly silicone material, supporting the cup body 11 and providing a temperature buffer between the cup body 11 and the insulation cover 1312. The bottom end of the cup body 11 and the insulation seat 1314 can be matingly connected, for example, with one of the cup body 11 and the insulation having a protrusion and the other having a groove, which matingly connects to securely secure the cup body 11 to the insulation seat 1314.

[0056] Please continue to refer to Figure 5 、 Figure 6 and Figure 7Furthermore, the fixing assembly 132 includes a fixing seat 1322 and an adjusting ring 1323. The fixing seat 1322 is installed on the top of the heat insulation assembly 131 and is used to install the suction nozzle 14; the mounting hole 1321 is located on the fixing seat 1322, and the mounting hole 1321 is connected to the opening of the heat insulation assembly 131 for aerosol vapor to flow in; the top of the fixing seat 1322 has a notch 13221; the adjusting ring 1323 is fixedly sleeved on the top of the fixing seat 1322, and the adjusting ring 1323 can be fixed to the fixing seat 1322 by riveting; the outer periphery of the adjusting ring 1323 is provided with a plurality of through holes 13231; the plurality of through holes 13231 are all connected to the notch 13221, and form a second channel 152 with the notch 13221, and the external air flow enters the third channel 153 and flows through several The through hole 13231 and the notch 13221 lead to the first channel 151. The connecting portion 143 is fitted around the outer circumference of the adjusting ring 1323 and is rotatable relative to the axial direction of the adjusting ring 1323. The third channel 153 located on the connecting portion 143 communicates with the plurality of through holes 13231 on the adjusting ring 1323. By rotating the connecting portion 143 relative to the adjusting ring 1323, at least some of the through holes 13231 in the third channel 153 of the connecting portion 143 are offset, that is, at least some of the through holes 13231 are not connected to the third channel 153. By rotating the connecting portion 143 (i.e., the mouthpiece 14), the number of through holes 13231 connected to the third channel 153 is changed, thereby adjusting the intake airflow intensity. During use, after twisting and unscrewing the mouthpiece 14, the aerosol-generating substrate is manually dripped into the cup. The mouthpiece 14 is then pressed onto the adjusting ring 1323, and the user can then inhale. The number of through holes 13231 can be set according to design requirements, for example, three, which can achieve three-level airflow intensity adjustment and improve the flexibility of the atomizer 10; Figure 8 、 Figure 9 and Figure 10 As shown, the user can adjust the mouthpiece 14 according to their preferences, selecting one to three through-holes 13231 for air intake. This results in varying airflow intensities and, consequently, varying airflow temperatures entering the user's mouth. Furthermore, airflow intensity adjustment can be tailored to the aerosol-generating matrix of different flavors, enhancing the personalization of the atomizer 10. If the second channel 152 is symmetrically distributed between the adjustment ring 1323 and the fixing base 1322, there are two notches 13221 and six through-holes 13231. The adjustment ring 1323 can be made of stainless steel, such as SUS304; the fixing base 1322 can be made of high-performance engineering plastic PEEK (polyetheretherketone). The fixing assembly 132 also includes a seal 1324, which seals between the fixing base 1322 and the thermal insulation assembly 131, enhancing the seal between the fixing base 1322 and the thermal insulation assembly 131 and preventing air leaks that could cause aerosol leakage.
