[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: The first aspect of this application provides an atomizing core base for an atomizing core assembly. The atomizing core assembly includes an atomizing bracket, and the atomizing core base is inserted into the atomizing bracket. Multiple limiting grooves are provided on the outer circumferential side of the atomizing core base, and these grooves are spaced apart along the circumferential direction of the atomizing core base. Each limiting groove includes a first groove segment and a second groove segment, which are connected and sequentially arranged along the direction from one end to the other of the atomizing core base. The first groove segment includes a first edge and a second edge arranged opposite to each other along the circumferential direction of the atomizing core base, and the second groove segment includes a third edge and a fourth edge arranged opposite to each other along the circumferential direction of the atomizing core base. The first edge and the third edge are connected, and the second edge and the fourth edge are connected. Along the circumferential direction of the atomizing core base, the first edge protrudes from the third edge in a direction away from the second edge, and / or the second edge protrudes from the fourth edge in a direction away from the first edge.

[0005] In some implementations, the first groove segment includes a first groove wall and a second groove wall, which are arranged sequentially along the circumference of the atomizing core base. A first edge is formed between the first groove wall and the outer side of the atomizing core base, and a second edge is formed between the first groove wall and the outer side of the atomizing core base. The groove depth of the first groove wall gradually decreases along the direction from the side where the first groove wall connects to the second groove wall to the first edge. And / or, the groove depth of the second groove wall gradually decreases along the direction from the side where the second groove wall connects to the first groove wall to the second edge.

[0006] In some implementations, the distance between the first edge and the second edge first increases and then decreases along the direction from the first slot segment to the second slot segment.

[0007] In some implementations, the outer peripheral side of the atomizer core base includes a first region surface and a second region surface, which are arranged sequentially along the direction from one end to the other of the atomizer core base; the diameter of the second region surface is larger than the diameter of the first region surface, and the diameter of the first region surface gradually increases from the end away from the second region surface to the end connected to the second region surface; a second groove segment is arranged on the second region surface, and the first groove segment is arranged at least on the first region surface.

[0008] In some implementations, the first edge of the first slot segment is connected to the second edge of another first slot segment adjacent to the first edge; or, there is a gap between the first edge of the first slot segment and the second edge of another first slot segment adjacent to the first edge, and the gap is smaller than a preset reference value.

[0009] In some implementations, the second slot segment includes a main limiting slot and a slot end. The main limiting slot connects the first slot segment and the slot end. The slot end extends to the end face of the atomizing core base. In the first slot segment and the slot end, at least the main limiting slot can cooperate with the atomizing bracket to secure the pins on the heating element between the atomizing core base and the atomizing bracket.

[0010] In some implementations, the outer peripheral side of the atomizing core base includes a second main area surface and an edge area surface. The edge area surface is located at one end of the second main area surface and the two are connected. The main limiting groove and the groove end are respectively located on the second main area surface and the edge area surface. The diameter of the edge area surface is smaller than the diameter of the second main area surface.

[0011] In some implementations, the depth of the groove end recess is greater than the depth of the main limiting groove recess. The groove end can cooperate with the atomizing bracket to fix the pin between the atomizing core base and the atomizing bracket, or the pin can be movably set between the groove end and the atomizing bracket.

[0012] In some implementations, the main limiting groove is arc-shaped; and / or, the end of the groove is arc-shaped.

[0013] The second aspect of this application provides an atomizing core assembly, including an atomizing bracket, an inner liquid guiding component, a heating element, and an atomizing core base provided by any of the above technical solutions.

[0017] The beneficial effects of this application are as follows: The atomizer core base provided in this application embodiment can be inserted into the atomizer bracket from one end of the atomizer cover. Since multiple limiting grooves are provided on the outer circumference side of the atomizer core base, each pin of the heating element can pass through the corresponding limiting groove to exit the atomizer cover. That is, the atomizer core base can separate each pin to avoid the pins from contacting each other and causing a short circuit as much as possible. In addition, the limiting groove includes a first groove segment and a second groove segment. The first groove segment includes a first edge and a second edge that are arranged opposite to each other in the circumferential direction of the atomizer core base. The second groove segment includes a third edge and a fourth edge that are arranged opposite to each other in the circumferential direction of the atomizer core base. By setting the third edge to protrude from the first edge to the side opposite to the second edge and / or the fourth edge to protrude from the second edge to the side opposite to the first edge, the protruding part of the first edge and / or the second edge can help increase the width of the second groove segment in the circumferential direction of the atomizer core base. When the atomizer core base is inserted into the atomizer bracket, it is easy for the pins to be positioned in the corresponding first groove segment, so as to facilitate the installation of the atomizer core base.

[0045] In this embodiment, by setting a third edge 26121 protruding from the first edge 26111 to the side opposite to the second edge 26112 and / or a fourth edge 26122 protruding from the second edge 26112 to the side opposite to the first edge 26111, the protruding portions of the first edge 26111 and / or the second edge 26112 can help increase the width of the second groove segment 2612 along the circumferential direction of the atomizing core base 26. When the atomizing core base 26 is inserted into the atomizing bracket 21, it is convenient for the pin 232 to be positioned in the corresponding first groove segment 2611, so as to facilitate the installation of the atomizing core base 26.

[0046] In some embodiments, see Figure 8The first groove segment 2611 includes a first groove wall 26113 and a second groove wall 26114. The first groove wall 26113 and the second groove wall 26114 are arranged sequentially along the circumference of the atomizing core base 26. A first edge 26111 is formed between the first groove wall 26113 and the outer side of the atomizing core base 26, and a second edge 26112 is formed between the second groove wall 26114 and the outer side of the atomizing core base 26.

[0047] In the embodiments of this application, the groove depth of the first groove wall 26113 gradually decreases along the direction from the side where the first groove wall 26113 connects to the second groove wall 26114 to the first edge 26111, and / or the groove depth of the second groove wall 26114 gradually decreases along the direction from the side where the second groove wall 26114 connects to the first groove wall 26113 to the second edge 26112.

[0048] In some examples, the first groove wall 26113 and / or the second groove wall 26114 can be set as curved surfaces; or, in other examples, please refer to [link to relevant documentation]. Figure 8 Along the direction from the side connected to the second groove wall 26114 to the first edge 26111, the first groove wall 26113 is inclined away from the second groove wall 26114; and / or, along the direction from the side connected to the first groove wall 26113 to the second edge 26112, the second groove wall 26114 is inclined away from the first groove wall 26113. Please refer to [link to relevant documentation]. Figure 8 The dashed line L indicates the midpoint where the first groove wall 26113 connects to the second groove wall 26114. Figure 8The diagram illustrates that, along the direction from the middle position to the first edge 26111, the first groove wall 26113 is inclined away from the second groove wall 26114, and along the direction from the middle position to the second edge 26112, the second groove wall 26114 is inclined away from the first groove wall 26113. Alternatively, the first groove wall 26113 can be inclined only along the direction from the middle position to the first edge 26111, or only along the direction from the middle position to the second edge 26112, the second groove wall 26114 can be inclined away from the first groove wall 26113. When the first groove wall 26113 is tilted away from the second groove wall 26114 and the second groove wall 26114 is tilted away from the first groove wall 26113, in some scenarios, during the process of inserting the atomizing core base 26 into the atomizing bracket 21, the protective sleeve 2322 on the pin 232 passes through the corresponding limiting groove 261. If the protective sleeve 2322 contacts the first groove wall 26113, the protective sleeve 2322 can be guided along the first groove wall 26113 to the middle position of the first groove segment 2611. If the protective sleeve 2322 contacts the second groove wall 26114, the protective sleeve 2322 can be guided along the second groove wall 26114 to the middle position of the first groove segment 2611.

[0049] In this embodiment, by gradually reducing the depth of the first groove wall 26113 and / or the second groove wall 26114, the protective sleeve 232 on the pin 232 can be guided to move along the first groove wall 26113 or the second groove wall 26114 to the middle position of the first groove segment 2611 when the atomizing core base 26 is inserted into the atomizing cover 25, so as to press the protective sleeve 2322 between the limiting groove 261 and the atomizing bracket 21.

[0050] In some embodiments, see Figure 9 The outer peripheral side of the atomizer core base 26 includes a first region surface 262 and a second region surface 263. The first region surface 262 and the second region surface 263 are arranged sequentially along the direction from one end to the other of the atomizer core base 26, that is, the first region surface 262 and the second region surface 263 are arranged along the direction from one end to the other. Figure 9 The first end face 264 is provided on one side in the direction from the second end face 265, wherein the second groove segment 2612 is provided on the first groove segment 2611 away from the first end face 264.

[0051] Please see Figure 9The diameter of the second region surface 263 is larger than the diameter of the first region surface 262. The diameter of the first region surface 262 gradually increases from the end away from the second region surface 263 (i.e., the first end surface 264) to the end connected to the second region surface 263. The second groove segment 2612 is disposed on the second region surface 263, and the first groove segment 2611 is disposed at least on the first region surface 262.

[0052] The first slot segment 2611 is at least provided on the first region surface 262, that is, the first slot segment 2611 can be provided only on the first region surface 262, or, please refer to Figure 9 The first groove segment 2611 is located not only on the first region surface 262, but also part of the first groove segment 2611 is located on the second region surface 263.

[0053] In this embodiment, the diameter of the first region surface 262 gradually increases from one end away from the second region surface 263 to the end connected to the second region surface 263, so that the first end face 264 of the atomizing core bracket can be inserted into the atomizing bracket 21; the second groove segment 2612 is provided on the second region surface 263 so that the protective sleeve 2322 can be squeezed between the second groove segment 2612 and the atomizing bracket 21.

[0054] In some embodiments, see Figure 9 Along the direction from the first groove segment 2611 to the second groove segment 2612, the distance between the first edge 26111 and the second edge 26112 first increases and then decreases.

[0055] Please see Figure 9 The atomizer core base 26 includes a first end face 264 and a second end face 265. A second groove segment 2612 is disposed in the first groove segment 2611 away from the first end face 264. In some examples, please refer to Figure 9 The first edge 26111 and the second edge 26112 may not extend to the first end face 264, and one end of the first edge 26111 may be connected to one end of the second edge 26112; or, in other examples, the first edge 26111 and the second edge 26112 of the first groove segment 2611 may be formed on the first end face 264.

[0056] Please see Figure 9 In this embodiment of the application, the diameter of the second region surface 263 may be set to be larger than the diameter of the first region surface 262, from one end away from the second region surface 263 (i.e., the first end surface 264) to the end connected to the second region surface 263.

[0057] In this embodiment of the application, by setting the distance between the first edge 26111 and the second edge 26112 along the direction from the first groove segment 2611 to the second groove segment 2612 to first increase and then decrease, it is convenient for the first groove segment 2611 to be formed on the atomizing core base 26.

[0058] In some embodiments, see Figure 9 The first edge 26111 of the first groove segment 2611 is connected to the second edge 26112 of another first groove segment 2611 adjacent to the first edge 26111.

[0059] For example, two adjacent first slot segments 2611 are called first slot segment one and first slot segment two, respectively. The first edge 26111 of first slot segment one and the second edge 26112 of first slot segment two are adjacent and connected.

[0060] In this embodiment of the application, by setting the first edge 26111 in the first slot segment 2611 and the second edge 26112 of another first slot segment 2611 adjacent to the first edge 26111 to be connected, the protective sleeve 2322 on the pin 232 is positioned in the corresponding first slot segment 2611.

[0061] The above embodiment describes the connection between the first edge 26111 of the first groove segment 2611 and the second edge 26112 of another first groove segment 2611 adjacent to the first edge 26111. In other embodiments, there is a gap between the first edge 26111 of the first groove segment 2611 and the second edge 26112 of another first groove segment 2611 adjacent to the first edge 26111, and the gap is smaller than a preset reference value.

[0062] For example, two adjacent first groove segments 2611 are called first groove segment one and first groove segment two, respectively, and there is a gap between the first edge 26111 of first groove segment one and the second edge 26112 of first groove segment two.

[0063] In some examples, the preset reference value can be set to a range of 0.5mm to 5mm. For example, when the preset reference value is 1mm, there is a gap of less than 1mm between the first edge 26111 of the first groove segment 1 and the second edge 26112 of the first groove segment 2.

[0064] In this embodiment of the application, by setting a gap between the first edge 26111 in the first slot segment 2611 and the second edge 26112 of another first slot segment 2611 adjacent to the first edge 26111 that is less than a preset reference value, it is also convenient for the protective sleeve 2322 on the pin 232 to be positioned in the corresponding first slot segment 2611.

[0065] In some embodiments, see Figure 9The second groove segment 2612 includes a main limiting groove portion 26123 and a groove end portion 26124. The main limiting groove portion 26123 connects the first groove segment 2611 and the groove end portion 26124. The groove end portion 26124 extends to the end face of the atomizing core base 26. Among the first groove segment 2611 and the groove end portion 26124, at least the main limiting groove portion 26123 can cooperate with the atomizing bracket 21 to secure the pins 232 on the heating element 23 between the atomizing core base 26 and the atomizing bracket 21.

[0066] Regarding the fact that at least the main limiting groove 26123 can cooperate with the atomizing bracket 21 to secure the pins 232 on the heating element 23 between the atomizing core base 26 and the atomizing bracket 21, it can be understood that only the main limiting groove 26123 can cooperate with the atomizing bracket 21 to secure the pins 232 on the heating element 23 between the atomizing core base 26 and the atomizing bracket 21, or the main limiting groove 26123 and the groove end 26124 can both cooperate with the atomizing bracket 21 to secure the pins 232 on the heating element 23 between the atomizing core base 26 and the atomizing bracket 21.

[0067] In this embodiment, by setting the main limiting groove 26123, the pin 232 on the heating element 23 can be fixed between the atomizing core base 26 and the atomizing bracket 21 in conjunction with the atomizing bracket 21. This not only limits the position of the pin 232, but also fixes the atomizing core base 26 inside the atomizing bracket 21 by pressing the pin 232 against the inner side of the atomizing bracket 21.

[0068] In some embodiments, see Figure 8 The depth of the recess at the end of the groove 26124 is greater than the depth of the recess in the main limiting groove 26123.

[0069] Regarding the fact that the depth of the recess at the end of the groove 26124 is greater than the depth of the recess in the main limiting groove 26123, it can be understood that, on the longitudinal section of the atomizing core base 26 (the longitudinal section passes through the central axis of the atomizing core base 26), the radial distance from the end of the groove 26124 to the central axis of the atomizing core base 26 is less than the radial distance from the main limiting groove 26123 to the central axis of the atomizing core base 26.

[0070] In this embodiment, the slot end 26124 can be configured to cooperate with the atomizing bracket 21 to secure the pin 232 between the atomizing core base 26 and the atomizing bracket 21; or, the pin 232 can be movably disposed between the slot end 26124 and the atomizing bracket 21, that is, the pin 232 is not squeezed between the slot end 26124 and the atomizing bracket 21.

[0071] When the groove end 26124 can cooperate with the atomizing bracket 21 to fix the pin 232 between the atomizing core base 26 and the atomizing bracket 21, the depth of the groove end 26124 is greater than the depth of the main limiting groove 26123, so the squeezing force of the groove end 26124 and the atomizing bracket 21 on the pin 232 is less than the squeezing force of the main limiting groove 26123 and the atomizing bracket 21 on the pin 232.

[0072] In some scenarios, please refer to Figure 11 The pin 232, protruding from the end of the groove 26124, is immediately bent. If the compressive force on the pin 232 at the end of the groove 26124 is equal to the compressive force on the pin 232 by the main limiting groove 26123 and the atomizing bracket 21, the stress on the pin 232 at the end of the groove 26124 may be relatively concentrated. However, by setting the depth of the recess at the end of the groove 26124 to be greater than the depth of the recess in the main limiting groove 26123, it is beneficial to reduce the stress on the pin 232 at the end of the groove 26124. It should be noted that... Figure 11 The diagram only illustrates one pin 232 and does not imply that the heating element 23 includes only one pin 232.

[0073] In this embodiment of the application, by setting the depth of the recess at the end of the groove 26124 to be greater than the depth of the recess in the main limiting groove 26123, the stress on the pin 232 can be improved.

[0074] In some embodiments, see Figure 8 The cross-section of the main limiting groove 26123 is arc-shaped. It should be noted that the cross-section of the main limiting groove 26123 refers to the surface perpendicular to the axis of the atomizing core base 26.

[0075] In this embodiment, the cross-section of the main limiting groove 26123 is set to be arc-shaped so as to match the shape of the protective sleeve 2322 on the pin 232, thereby stably pressing the pin 232 between the main limiting groove 26123 and the atomizing bracket 21.

[0076] In some embodiments, the cross-section of the groove end 26124 is arc-shaped. It should be noted that the cross-section of the main limiting groove 26123 refers to the surface perpendicular to the axis of the atomizing core base 26.

[0077] In this embodiment, the cross-section of the groove end 26124 is set to be arc-shaped to match the shape of the protective sleeve 2322 on the pin 232, and also to facilitate the forming of the groove end 26124 on the atomizing core base 26.

[0078] It should be noted that the cross-section of the groove end 26124 is not limited to being only arc-shaped. For example, when the pin 232 is movably disposed between the groove end 26124 and the atomizing bracket 21, the shape of the cross-section of the groove end 26124 can be set to be U-shaped or square.

[0079] In some embodiments, see Figure 9 The second region surface 263 includes a second main region surface 2631 and an edge region surface 2632. The second main region surface 2631 and the edge region surface 2632 are arranged along one side of the axis of the atomizing core. The second main region surface 2631 connects the first region surface 262 and the edge region surface 2632. The diameter of the edge region surface 2632 is smaller than the diameter of the second main region surface 2631. The groove end 26124 is arranged on the edge region surface 2632, and the main limiting groove 26123 is arranged on the second main region surface 2631.

[0080] In this embodiment of the application, by setting the diameter of the edge region surface 2632 to be smaller than the diameter of the second main region surface 2631, the depth of the groove end 26124 recess is greater than the depth of the main limiting groove 26123 recess.

[0081] In some embodiments, see Figure 10 A central hole 266 is provided on the atomizing core base 26, and the two ends of the central hole 266 are respectively connected to the two opposite end faces of the atomizing core base 26.

[0082] In this embodiment, a central hole 266 is provided on the atomizer core base 26 to reduce the weight of the atomizer core base 26 and save the materials used in producing the atomizer core base 26.

[0083] In some embodiments, there is one or more heating elements 23, and each heating element 23 is provided with pins 232. Each pin 232 extends out of the atomizing bracket 21 through the corresponding limiting groove 261 on the atomizing core base 26.

[0084] For example, the number of heating elements 23 can be set to one, or the number of heating elements 23 can be set to two, three or four, etc., and each heating element 23 is located inside the inner liquid guiding element 22.

[0085] It should be noted that the number of upper limit slots 261 in the atomizer core base 26 is not limited to the number of pins 232. Usually, the number of upper limit slots 261 is greater than the number of pins 232.

[0086] In this embodiment of the application, by setting one or more heating elements 23, an appropriate number of heating elements 23 can be selected according to the needs.

[0087] In some embodiments, see Figure 5 and Figure 6 A first sealing element 27 is provided on the atomizing outer cover 25. The first sealing element 27 is close to one end of the atomizing outer cover 25. There is more than one first sealing element 27. The first sealing element 27 is used to seal the inner side of the atomizing core assembly 20 and the chamber 10.

[0088] In some examples, the number of first seals 27 can be more than two; see [link to relevant documentation]. Figure 5 This illustrates that the atomizer core assembly 20 is provided with two first seals 27 to improve the sealing between the atomizer core assembly 20 and the inner side of the chamber 10.

[0089] In some embodiments, see Figure 6 The atomizer core assembly 20 also includes a second seal 28, see [link to documentation]. Figure 5 The atomizing outer cover 25 includes an outer cover main body 252 and a constricted neck 253. The constricted neck 253 is disposed at one end of the outer cover main body 252 and the two are connected. The constricted neck 253 is used to seal with the chamber 10. The outer liquid guide 24, the atomizing bracket 21, the inner liquid guide 22 and the heating element 23 are disposed inside the outer cover main body 252.

[0090] Please see Figure 6 The second seal 28 is sleeved between the outer cover body 252 and the atomizing bracket 21. The second seal 28 is located away from the atomizing core base 26. The upper limit of the second seal 28 along the axial direction is between the end face of the outer liquid guide 24 and the constriction neck 253.

[0091] In this embodiment, the atomizer 100 assembly also includes a second sealing member 28, which is used to limit the position of one end of the external liquid guide member 24 and also prevent the aerosol matrix in the external liquid guide member 24 from flowing to the neck 253.

[0092] In some embodiments, see Figure 6 The atomizing core assembly 20 also includes a third seal 29, which is sleeved between the atomizing bracket 21 and the atomizing outer cover 25. The third seal 29 is located at the other end of the outer liquid guide 24. Please refer to [link to relevant documentation]. Figure 6 The third sealing element 29 is fitted around the outer periphery of the atomizing core base 26.

[0093] In this embodiment, by providing a third sealing element 29 to the atomizing core assembly 20, the position of the other end of the external liquid guide 24 can be limited, and at the same time, the aerosol matrix in the external liquid guide 24 is prevented from flowing out of the atomizing core assembly 20.

[0094] This application provides an atomizing device, including a battery rod and an atomizer 100 provided in any of the above embodiments, wherein the battery rod is connected to the atomizer 100.

[0095] Regarding the battery section, it typically contains a battery and circuit boards, etc. The battery section provides the necessary power to the atomizer 100 through the built-in battery, enabling the atomizer 100 to work normally.

[0096] Regarding the connection method between the battery section and the atomizer 100, the battery section and the atomizer 100 can be detachably connected, for example, they can be connected by a snap-fit ​​or magnetic adsorption; or, the battery section and the atomizer 100 can be non-detachably connected.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
