An atomizer includes an atomizing coil assembly for heating the aerosol matrix, which includes a heating element that generates heat when an electric current flows through it. Some existing heating elements are prone to clogging, which affects the atomizer's lifespan. Utility Model Content

[0003] The purpose of this application is to provide a heating element, an atomizing core assembly, an atomizer, and an atomizing device to solve the technical problem that the structure of some heating elements in the prior art causes the atomizer to easily produce a burnt core.

[0014] In some implementations, when the heating element is in operation, along the direction from the first end to the second end and in two adjacent heating regions, the temperature of each heating structure in the heating region closer to the first end is lower than the temperature of each heating structure in the heating region closer to the second end.

[0033] Please see Figures 3-4 , Figure 3 This is a cross-sectional schematic diagram of the atomizer 10 provided in some embodiments of this application. Figure 4 An exploded schematic diagram of the atomizer 10 provided in some embodiments of this application.

[0034] Please see Figure 3 The atomizer 10 provided in this application embodiment includes a liquid storage chamber assembly 1, a base assembly 2, and an atomizing core assembly 3. The atomizing core assembly 3 is located inside the liquid storage chamber assembly 1. The base assembly 2 is inserted into the liquid storage chamber assembly 1 from the bottom and is sealed to the inner wall of the liquid storage chamber assembly 1. The two ends of the atomizing core assembly 3 are sealed to the liquid storage chamber assembly 1 and the base assembly 2, respectively. The liquid storage chamber assembly 1, the base assembly 2, and the atomizing core assembly 3 together form a liquid storage cavity 4, which is used to store the aerosol matrix.

[0035] Please see Figure 3 The liquid storage tank assembly 1 includes a liquid storage tank body 11 and a nozzle part 12. The nozzle part 12 is disposed at one end of the liquid storage tank body 11 away from the base assembly 2. An airflow channel 121 is formed on the nozzle part 12.

[0037] In this embodiment, the atomizing core assembly 3 is electrically connected to the battery assembly 20. The atomizing core assembly 3 is used to heat the aerosol matrix that has penetrated into it. Specifically, the aerosol matrix in the liquid storage chamber 4 can penetrate into the atomizing core assembly 3.

When it is used to draw into the mouthpiece 12, there is airflow in the atomizing core assembly 3. The flowing airflow condenses and heats the evaporated aerosol matrix to form an aerosol.

[0038] Please see Figures 5-6 , Figure 5 This is a schematic diagram of the structure of the atomizing core assembly 3 provided in some embodiments of this application. Figure 6 This is a cross-sectional schematic diagram of the atomizing core assembly 3 provided in some embodiments of this application.

[0039] In some embodiments, see Figure 6 The atomizing core assembly 3 includes a heating element 31, an inner liquid guiding element 32, and an atomizing bracket 33. The heating element 31, the inner liquid guiding element 32, and the atomizing bracket 33 are sequentially arranged from the inside to the outside. The heating element 31 is used to electrically connect with the battery assembly 20.

[0040] The internal fluid guiding component 32 is cylindrical; please refer to [link / reference]. Figure 6 The heating element 311 is located inside the inner liquid guiding component 32, which has the functions of storing and guiding liquid. In some examples, the material of the inner liquid guiding component 32 can be set to organic cotton, ceramic cotton, bamboo fiber cotton or composite cotton, etc.

[0041] In some embodiments, see Figure 6 The atomizing core assembly 3 also includes an atomizing outer cover 35 and an outer liquid guiding component 34. The outer liquid guiding component 34 is sleeved outside the atomizing bracket 33, and the atomizing outer cover 35 is sleeved outside the outer liquid guiding component 34.

[0042] The outer liquid guide 34 is cylindrical and is sleeved outside the atomizing bracket 33. The inner liquid guide 32 has the function of storing and guiding liquid. In some examples, the material of the inner liquid guide 32 can be organic cotton, ceramic cotton, bamboo fiber cotton or composite cotton, etc.

[0043] Please see Figure 6 The atomizing outer cover 35 is installed outside the outer liquid guiding component 34. Please refer to [link / reference]. Figure 5 The atomizing outer cover 35 is provided with a liquid guiding hole 351, which is close to the bottom of the atomizing core assembly 3. The atomizing bracket 33 is provided with a liquid inlet hole. The aerosol matrix in the liquid storage chamber 4 can flow to the outer liquid guiding component 34 through the liquid guiding hole 351 on the atomizing outer cover 35. The aerosol matrix that has penetrated into the outer liquid guiding component 34 can flow to the inner liquid guiding component 32 through the liquid inlet hole on the atomizing bracket 33.

[0044] Please see Figures 7-10, Figure 7 This is a schematic diagram of the structure of the heating element 31 provided in some embodiments of this application. Figure 8 This is a cross-sectional schematic diagram of the atomizer 10 provided in some embodiments of this application. Figure 9 Schematic diagram of temperature field distribution of heating element 31 provided in some embodiments of this application Figure 1 , Figure 10 Schematic diagram of temperature field distribution of heating element 31 provided in some embodiments of this application Figure 2 .

[0045] Please see Figure 7 The heating element 31 provided in this embodiment includes at least two heating structures 3111, and the heating structures 3111 are arranged sequentially at intervals along the axial direction of the heating element 31. Please refer to... Figure 7 The heating element 31 includes a first end 313 and a second end 314 along its own axis, wherein, please refer to Figure 8 The first end 313 is used near the top of the atomizing core assembly 3, that is, the first end 313 is near... Figure 8 The nozzle section 12 of the atomizer.

[0046] In this embodiment, when the heating element 31 is in operation, the temperature of the heating structure 3111 near the first end 313 is lower than the temperature of the heating structure 3111 near the second end 314. It should be noted that the heating structure 3111 near the first end 313 refers to the heating structure 3111 closest to the first end 313 in the heating element 31, and the heating structure 3111 near the second end 314 refers to the heating structure 3111 closest to the second end 314 in the heating element 31.

[0047] For ease of description, the heating structure 3111 near the first end 313 is referred to as the first heating structure 3112, and the heating structure 3111 near the second end 314 is referred to as the second heating structure 3113. Please refer to [link / reference]. Figure 9 and Figure 10 The image shows the temperature field distribution of the heating element 31 obtained through simulation. The redder the color of the heating structure 3111, the higher its temperature. Please refer to [link to relevant documentation]. Figure 9 and Figure 10 This indicates that the temperature of the first heating structure 3112 is lower than the temperature of the second heating structure 3113.

[0048] Please see Figure 8The liquid level line in the storage cavity 4 is indicated by the dashed line L. At this time, the liquid level line is located below the first heating structure 3112 and above the second heating structure 3113. The aerosol matrix immersed in the inner liquid guide 32 and the outer liquid guide 34 above the liquid level line is relatively small. Assuming that when the heating element 31 is in working state, the temperature of the heating structure 3111 (i.e., the first heating structure 3112) near the first end 313 is equal to the temperature of the heating structure 3111 (i.e., the second heating structure 3113) near the second end 314, it is possible that the area of ​​the inner liquid guide 32 heated by the first heating structure 3112 will become scorched. However, in this embodiment, by setting the temperature of the first heating structure 3112 to be lower than the temperature of the second heating structure 3113 when the heating element 31 is in working state, it is beneficial to prevent the area of ​​the inner liquid guide 32 corresponding to the first heating structure 3112 from becoming scorched.

[0049] In summary, in this embodiment of the application, by setting the temperature of the heating structure 3111 near the first end 313 to be lower than the temperature of the heating structure 3111 near the second end 314 when the heating element 31 is in working state, when the atomizer 10 with the heating element 31 is provided has a reduced aerosol matrix content, it is beneficial to prevent the atomizer core assembly 3 from having a clogging problem in the area corresponding to the inner liquid guiding element 32 and the first heating structure 3112, thereby preventing the atomizer core assembly 3 from having a clogging problem.

[0050] In some embodiments, when the heating element 31 is in operation, the temperature of the heating structure 3111 near the first end 313 is lower than the temperature of the heating structure 3111 near the second end 314, and the temperature difference between the two can be set to a range of 50℃-200℃.

[0051] In some examples, the temperature difference between the first heating structure 3112 and the second heating structure 3113 when the heating element 31 is in operation can be set to 50℃-100℃, 100℃-150℃, or 150℃-200℃, etc. It should be noted that a reasonable temperature difference between the first heating structure 3112 and the second heating structure 3113 can be set according to the temperature requirements of different heating structures 3111.

[0052] Please see Figure 11-12 , Figure 11 A schematic diagram of the unfolded heating element 31 provided in some embodiments of this application. Figure 1 , Figure 12 A schematic diagram of the unfolded heating element 31 provided in some embodiments of this application. Figure 2 .

[0053] In some embodiments, the resistance of the first heating structure 3112 is equal to or less than the resistance of the second heating structure 3113, and the surface area of ​​the first heating structure 3112 is greater than the surface area of ​​the second heating structure 3113.

[0054] In some examples, the resistance of the heating structure 3111 near the first end 313 is equal to the resistance of the heating structure 3111 near the second end 314, i.e., see [reference needed]. Figure 12 The resistance of the first heating structure 3112 is set to be the same as the resistance of the second heating structure 3113, and the surface area of ​​the first heating structure 3112 is set to be larger than the surface area of ​​the second heating structure 3113. When the resistance of the first heating structure 3112 and the resistance of the second heating structure 3113 are the same, according to the formula... Since the first heating structure 3112 and the second heating structure 3113 are connected in parallel, when the heating element 31 is in working condition, the voltage of the first heating structure 3112 and the second heating structure 3113 is the same. Since their resistances are also the same, the heat generated by the first heating structure 3112 is the same as the heat generated by the second heating structure 3113. By setting the surface area of ​​the first heating structure 3112 to be larger than the surface area of ​​the second heating structure 3113, the heat concentration of the first heating structure 3112 can be reduced, thereby achieving a temperature of the first heating structure 3112 that is lower than the temperature of the second heating structure 3113 when the heating element 31 is in working condition.

[0055] In some examples, the resistance of the heating structure 3111 near the first end 313 is less than the resistance of the heating structure 3111 near the second end 314, i.e., see [reference needed]. Figure 12 The resistance of the first heating structure 3112 is set to be less than the resistance of the second heating structure 3113, according to the formula. Since the first heating structure 3112 and the second heating structure 3113 are connected in parallel, when the heating element 31 is in working condition, the voltage of the first heating structure 3112 and the second heating structure 3113 is the same. The resistance of the first heating structure 3112 is less than the resistance of the second heating structure 3113, and thus the heat generated by the first heating structure 3112 is less than the heat generated by the second heating structure 3113. This makes it easier for the temperature of the first heating structure 3112 to be lower than the temperature of the second heating element 31. When the surface area of ​​the first heating structure 3112 is set to be greater than the surface area of ​​the second heating structure 3113, it is further made so that the temperature of the first heating structure 3112 is lower than the temperature of the second heating structure 3113 when the heating element 31 is in working condition.

[0056] In this embodiment, by limiting the resistance of the first heating structure 3112 to be equal to or less than the resistance of the second heating structure 3113, and by limiting the surface area of ​​the first heating structure 3112 to be greater than the surface area of ​​the second heating structure 3113, it is possible to achieve that when the heating element 31 is in working state, the temperature of the heating structure 3111 near the first end 313 is lower than the temperature of the heating structure 3111 near the second end 314.

[0057] It should be noted that for any two heating structures 3111 on the heating element 31, if the temperature of one heating structure 3111 is lower than the temperature of the other heating structure 3111 when the heating element 31 is in working state, the resistance of the heating structure 3111 with lower temperature can be set to be less than or equal to the resistance of the heating structure 3111 with higher temperature, and the surface area of ​​the heating structure 3111 with lower temperature is greater than the surface area of ​​the heating structure 3111 with higher temperature.

[0058] It should be noted that the heating temperature of the heating structure 3111 can be changed by altering its surface area. Therefore, different reasonable surface areas of the heating structure 3111 can be set according to the temperature requirements of different heating structures 3111.

[0059] In some embodiments, when the heating element 31 is in working state, the temperature of the first heating structure 3112 is not greater than the temperature of the other heating structures 3111 on the heating element 31 other than the first heating structure 3112, and the temperature of the second heating structure 3113 is not less than the temperature of the other heating structures 3111 on the heating element 31 other than the second heating structure 3113.

[0060] In this embodiment of the application, by limiting the heating temperature of the heating structure 3111 on the heating element 31, it is beneficial to prevent the atomizing core assembly 3 from clogging during operation.

[0061] In some embodiments, see Figure 11 and Figure 12 The heating structure 3111 is linear and has a continuous wave shape. The diameter of the first heating structure 3112 is larger than the diameter of the second heating structure 3113, and the length of the first heating structure 3112 is greater than the length of the second heating structure 3113.

[0062] Please see Figure 11 and Figure 12 The diagram illustrates that the wire diameter of the first heating structure 3112 is a1, and the wire diameter of the second heating structure 3113 is a2, where a1 is greater than a2. By setting the wire diameter of the first heating structure 3112 to be greater than that of the second heating structure 3113, the surface area of ​​the first heating structure 3112 is greater than that of the second heating structure 3113.

[0063] See some examples. Figure 11 and Figure 12 The first heating structure 3112 includes several continuous first V-shaped segments 31121, and the second heating structure 3113 includes several continuous second V-shaped segments 31131. The length of the first V-shaped segment 31121 along the direction from the first end 313 to the second end 314 is b1, and the length of the second V-shaped segment 31131 along the same direction is b2, where b1 is greater than b2. The included angle of the first V-shaped segments 31121 is c. 1. The included angle of the second V-shaped line segment 31131 is c2, and c1 is less than c2, which makes the line length of the first V-shaped line segment 31121 greater than the line length of the second V-shaped line segment 31131. The line length of the first heating structure 3112 is the sum of the lengths of all the first V-shaped line segments 31121, and the line length of the second heating structure 3113 is the sum of the lengths of all the second V-shaped line segments 31131. Therefore, the line length of the first heating structure 3112 is greater than the line length of the second heating structure 3113.

[0064] According to the formula for calculating resistance Where ρ is the resistivity of the conductor material. s is the wire length of the conductor, and s is the cross-sectional area of ​​the conductor. Since the wire diameter of the first heating structure 3112 is greater than that of the second heating structure 3113, the cross-sectional area of ​​the first heating structure 3112 is greater than that of the second heating structure 3113. When the materials of the first heating structure 3112 and the second heating structure 3113 are the same, by setting the wire length of the first heating structure 3112 to be greater than that of the second heating structure 3113, the resistance of the first heating structure 3112 can be equal to the resistance of the second heating structure 3113.

[0065] In this embodiment of the application, by limiting the wire diameter and wire length of the first heating structure 3112 and the second heating structure 3113, the surface area of ​​the first heating structure 3112 is greater than the surface area of ​​the second heating structure 3113 when the resistances of the first heating structure 3112 and the second heating structure 3113 are the same.

[0066] It should be noted that for any two heating structures 3111 on the heating element 31, if the temperature of one heating structure 3111 is lower than the temperature of the other heating structure 3111 when the heating element 31 is in working state, the wire diameter of the heating structure 3111 with the lower temperature can be set to be greater than the wire diameter of the heating structure 3111 with the higher temperature, and the wire length of the heating structure 3111 with the lower temperature can be greater than the wire length of the heating structure 3111 with the higher temperature.

[0067] It should be noted that the heating temperature of the heating structure 3111 can be changed by altering the wire diameter and length. Therefore, different reasonable wire diameters and lengths of the heating structure 3111 can be set according to the temperature requirements of different heating structures 3111.

[0068] Please see Figures 13-16 , Figure 13 This is a schematic diagram of the structure of the heating element 311 in the unfolded state provided in some embodiments of this application.

[0069] In some embodiments, see Figures 13-16 The heating element 31 includes a heating body 311, and there is at least one heating body 311. The heating body 311 includes a first connecting part 3114, a second connecting part 3115 and an intermediate body part 3116. The intermediate body part 3116 is connected to the first connecting part 3114 and the second connecting part 3115 at opposite ends along the bending direction. The first connecting part 3114 and the second connecting part 3115 are used to connect with the pin 312. The intermediate body part 3116 includes a heating structure 3111.

[0070] Please see Figure 11 and Figure 12 The heating element 31 also includes pins 312, at least two of which are connected to the first connection portion 3114 and the second connection portion 3115. The pins 312 are used to electrically connect to the battery assembly 20. When the heating element 311 conducts current, the heating element 311 can generate heat.

[0071] There must be at least one heating element 311. The number of heating elements 311 can be set to one or more. For example, please refer to [link / reference needed]. Figure 15 and Figure 16 This illustrates that there are two heating elements 311, and the first connecting portions 3114 of the two heating elements 311 are connected. Please refer to [link / reference needed]. Figure 12 The heating element 31 can be configured to include three pins 312, one of which is connected to the first connecting part 3114 of the two heating bodies 311, and the other two pins 312 are respectively connected to the second connecting part 3115 of the two heating bodies 311.

[0072] In some examples, the heating element 31 includes a heating body 311, in which case the intermediate body portion 3116 includes at least two heating structures 3111. See [link to relevant documentation]. Figure 13 The diagram illustrates that the central main body 3116 includes three heating structures 3111. Please refer to [link / reference]. Figure 14 This illustrates that the central main body 3116 includes two heating structures 3111.

[0073] See some examples. Figure 16 The heating element 31 includes two or more heating bodies 311, and each heating body 311 includes a heating structure 3111.

[0074] See some examples. Figure 15 The heating element 31 includes two or more heating bodies 311, and each heating body 311 includes two or more heating structures 3111.

[0075] In this embodiment, by setting the number of heating elements 311 to one, the structure of the heating element 31 can be simplified; by setting the number of heating elements 311 to two or more, it is possible to control the operation of different numbers of heating elements 311 according to the needs, so as to meet the needs of different heating aerosol matrices.

[0076] In some embodiments, see Figure 13 The middle main body 3116 also includes connecting lines 3110. Several connecting lines 3110 are connected between two adjacent heating structures 3111, and the length direction of the connecting lines 3110 is along the direction from the first end 313 to the second end 314.

[0077] In some embodiments, see Figure 13 The first heating structure 3112 has several connecting lines 3110 distributed on the side opposite to the second heating structure 3113; the second heating structure 3113 has several connecting lines 3110 distributed on the side opposite to the first heating structure 3112.

[0078] In some embodiments, when the heating element 31 is in operation, along the direction from the first end 313 to the second end 314 and among two adjacent heating structures 3111, the temperature of the heating structure 3111 closer to the first end 313 is lower than the temperature of the heating structure 3111 closer to the second end 314. That is, it can be understood that along the direction from the first end 313 to the second end 314, the heating temperature of each heating structure 3111 shows a decreasing trend.

[0079] In some examples, the heating element 31 may be configured to include three or more heating structures 3111, and when the heating element 31 is in working condition, the temperature difference between two adjacent heating structures 3111 is 10℃-100℃.

[0080] In this embodiment, the heating temperature of each heating structure 3111 is limited to a decreasing trend along the direction from the first end 313 to the second end 314, so as to prevent the atomizing core assembly 3 from becoming burnt.

[0081] In some embodiments, see Figure 13 The central main body 3116 has at least two heating regions 3117, which are arranged sequentially at intervals along the axial direction of the heating element 31. Each heating region 3117 includes at least one heating structure 3111. It should be noted that... Figure 13 The heating areas 3117 on the main body 3116 are outlined with dashed lines.

[0082] In some examples, each heating region 3117 may be configured to include the same number of heating structures 3111; or, in other examples, the number of heating structures 3111 in some heating regions 3117 may differ from the number of heating structures 3111 in other heating regions 3117.

[0083] In some embodiments, see Figure 13 The heating area 3117 near the first end 313 includes one heating structure 3111, and the heating area 3117 near the second end 314 includes two or more heating structures 3111.

[0084] For ease of description, please refer to Figure 13 The heating area 3117 near the first end 313 is referred to as the first heating area 31171, and the heating area 3117 near the second end 314 is referred to as the second heating area 31172. In some examples, the first heating area 31171 may include one heating structure 3111, and the second heating area 31172 may include two or more heating structures 3111. For example, please refer to [link to relevant documentation]. Figure 13 The second heating area 31172 can be set, which includes two heating structures 3111.

[0085] In this embodiment, by defining the heating area 3117 near the first end 313 as including one heating structure 3111, the heat generated in the heating area 3117 near the first end 313 is relatively small when the heating element 31 is working, which helps to prevent the atomizing core assembly 3 from becoming clogged; by defining the heating area 3117 near the second end 314 as including two or more heating structures 3111, the heating area 3117 near the second end 314 can generate enough heat to heat the aerosol matrix.

[0086] In some embodiments, see Figure 13The middle main body 3116 includes two heating regions 3117, which are a first heating region 31171 and a second heating region 31172, respectively. The first heating region 31171 is closer to the first end 313 than the second heating region 31172. The distance between two adjacent heating structures 3111 in the second heating region 31172 is smaller than the distance between two adjacent heating structures 3111 in the first heating region 31171 and the second heating region 31172.

[0087] Please see Figure 13 The distance between two adjacent heating structures 3111 in the second heating region 31172 is d1, and the distance between two adjacent heating structures 3111 in the first heating region 31171 and the second heating region 31172 is d2, wherein d1 is less than d2.

[0088] In this application, by limiting the distance between two adjacent heating structures 3111 in the second heating region 31172 to be less than the distance between two adjacent heating structures 3111 in the first heating region 31171 and the second heating region 31172, the heat generation in the upper section of the heating element 31 can be minimized, which helps to prevent the atomizing core assembly 3 from becoming clogged.

[0089] In some embodiments, for a heating region 3117 including two or more heating structures 3111, the surface area and resistance of each heating structure 3111 in the heating region 3117 are the same.

[0090] See some examples. Figure 13 The second heating region 31172 includes two heating structures 3111. The two heating structures 3111 have the same resistance and the same surface area, meaning they have the same wire diameter and length. Please refer to [link / reference]. Figure 9 This indicates that the two heating structures 3111 in the second heating area 31172 have the same color, meaning that when the heating element 31 is in working condition, the two heating structures 3111 in the second heating area 31172 have the same temperature.

[0091] In this embodiment of the application, by defining the heating region 3117, which includes two or more heating structures 3111, such that each heating structure 3111 has the same surface area and resistance, the processing of the heating element 31 is utilized.

[0092] In some embodiments, when the heating element 31 is in operation, along the direction from the first end 313 to the second end 314 and in two adjacent heating regions 3117, the temperature of each heating structure 3111 in the heating region 3117 near the first end 313 is lower than the temperature of each heating structure 3111 in the heating region 3117 near the second end 314.

[0093] See some examples. Figure 15 The heating element 311 positioned below is referred to as the second heating element 3119, and the heating element 311 positioned above is referred to as the first heating element 3118. The end of the first heating element 3118 facing away from the second heating element 3119 is referred to as the first end 313, and the end of the second heating element 3119 facing away from the first heating element 3118 is referred to as the second end 314. Please refer to [link / reference]. Figure 15 The second heating element 3119 includes a first heating region 31171 and a second heating region 31172. The second heating region 31172 of the second heating element 3119 is located near the second end 314. (See also: [link to documentation] in the second heating element 3119]) Figure 10 The red depth of each heating structure 3111 in the second heating region 31172 is greater than the red depth of the heating structure 3111 in the first heating region 31171, meaning the temperature of each heating structure 3111 in the second heating region 31172 is greater than the temperature of the heating structure 3111 in the first heating region 31171. Please refer to... Figure 15 The first heating element 3118 includes a first heating region 31171 and a second heating region 31172. Please refer to [link / reference]. Figure 10 In the first heating body 3118, the red depth of each heating structure 3111 in the second heating region 31172 is greater than the red depth of the heating structure 3111 in the first heating region 31171, that is, the temperature of each heating structure 3111 in the second heating region 31172 is greater than the temperature of the heating structure 3111 in the first heating region 31171.

[0094] Please see Figure 10 The red depth of the first heating region 31171 heating structure 3111 in the second heating body 3119 is greater than the red depth of the second heating region 31172 heating structure 3111 in the first heating body 3118. That is, the temperature of the first heating region 31171 heating structure 3111 in the second heating body 3119 is greater than the temperature of the second heating region 31172 heating structure 3111 in the first heating body 3118.

[0095] In this embodiment, by defining the direction from the first end 313 to the second end 314 and in two adjacent heating regions 3117, the temperature of each heating structure 3111 in the heating region 3117 near the first end 313 is lower than the temperature of each heating structure 3111 in the heating region 3117 near the second end 314, which helps to prevent the atomizing core assembly 3 from becoming clogged.
