References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0031] See also Figures 1-8 In one embodiment of the present application, a heating structure for an atomizer is provided, including: a heating component 100 and a bracket 200.

[0032] The heating assembly 100 includes a housing 110, a heating element 120, and a first electrode 130. The housing 110 defines a cavity for accommodating an aerosol-forming substrate. The heating element 120 is secured to the housing 110 and configured to heat the aerosol-forming substrate. The first electrode 130 is secured to the outer wall of the housing 110 and is connected to the heating element 120.

[0033] An assembly cavity is provided in the bracket 200, and the heating component 100 is placed in the assembly cavity. The receiving piece 110 and the bracket 200 are detachably connected. A second electrode 210 is provided in the bracket 200, and the second electrode 210 is used to be detachably electrically connected to the first electrode 130. The second electrode 210 is also used to connect to the control board.

[0034] When the receiving member 110 and the bracket 200 are connected, the second electrode 210 and the first electrode 130 are electrically connected.

[0035] Using the heating structure in the above embodiment, the heating component 100 is placed in the assembly cavity of the bracket 200, the receiving piece 110 in the heating component 100 and the bracket 200 are detachably connected, the first electrode 130 in the heating component 100 and the second electrode 210 in the bracket 200 are detachably connected, when the receiving piece 110 and the bracket 200 are connected, the second electrode 210 and the first electrode 130 are connected, so as to facilitate the connection between the heating element 120 and the control board, and when the heating element 120 fails, the heating element 120 can be replaced by replacing the heating component 100.

[0036] See also Figure 1-Figure 3 The heating component 100 also includes a lead 140, one end of the lead 140 is connected to the heating element 120, and the other end of the lead 140 is connected to the first electrode 130. For example, the two ends of the lead 140 are welded to the heating element 120 and the first electrode 130 respectively. When the end of the lead 140 is welded to the first electrode 130, the end of the lead 140 can be welded to the side of the first electrode 130 away from the second electrode 210. The lead 140 facilitates the electrical connection between the first electrode 130 and the heating element 120, so that the position setting of the heating element 120 can be more flexible. For example, the heating element 120 can be fixed in the receiving element 110 or fixed to the side wall of the receiving element 110. It can be understood that the first electrode 130, the second electrode 210 and the lead 140 are all configured as a pair, and the first electrode 130, the second electrode 210 and the lead 140 are arranged in a one-to-one correspondence.

[0037] Specifically, the heating element 120 is fixed in the receiving part 110, and the heating element 120 is used to insert the aerosol-forming matrix to exert a heating effect. Among them, the receiving part 110 can be tubular or cylindrical, and the heating element 120 can be needle-shaped, rod-shaped or tubular. When the receiving part 110 is cylindrical, the tube mouth of the receiving part 110 is used to allow the aerosol-forming matrix to be inserted into the receiving part 110, and the heating element 120 is fixed to the bottom of the tube in the receiving part 110. When the receiving part 110 is tubular, please refer to Figure 4 A adapter 121 is fixed to the bottom of the heating element 120, and the adapter 121 is fixed to the inner wall of the receiving element 110. At this time, the heating element 120 can be an integrated structure through the adapter 121 and the receiving element 110, or it can be an assembled structure. For example, the adapter 121 is disc-shaped, and the adapter 121 is fixed to the side wall of the receiving element 110 by means of threads, gluing, etc.

[0038] In other embodiments, the heating element 120 is fixed to the side wall of the receiving member 110. For example, the heating element 120 is fixed to the outer wall, the inner wall, or the inner side wall between the inner and outer walls of the receiving member 110. When the heating element 120 is fixed to the outer wall of the receiving member 110, the lead 140 may be provided as required. For example, in this case, the first electrode 130 is directly connected to the heating element 120, and the lead 140 may not be provided.

[0039] Please refer to the figure Figure 1-Figure 2 as well as Figure 5 Specifically, in the embodiment of the present application, a docking groove 220 is defined on the inner sidewall of the bracket 200. Both the docking groove 220 and the first electrode 130 are strip-shaped structures. The lengths of the docking groove 220 and the first electrode 130 are parallel to the axis of the receiving member 110. The first electrode 130 is fixed to the outer sidewall of the receiving member 110, and the first electrode 130 and the docking groove 220 are slidably connected. The sliding connection between the strip-shaped docking groove 220 and the strip-shaped first electrode 130 facilitates quick assembly and disassembly between the heating assembly 100 and the bracket 200.

[0040] The bracket 200 is also provided with a wire cavity 230, and the second electrode 210 is installed in the wire cavity 230. Part of the second electrode 210 is placed in the docking groove 220 to make line contact or surface contact with the first electrode 130. Figure 2-Figure 3 More specifically, the second electrode 210 is bent to form two approximately parallel structures, the longer section is placed in the wire loading cavity 230, and the shorter section is placed in the docking groove 220. The second electrode 210 placed in the docking groove 220 is in line contact or surface contact with the first electrode 130. The end of the longer section of the second electrode 210 is used to be electrically connected to the control board. The strip-shaped first electrode 130 and the second electrode 210 have a large contact area, which can effectively reduce the contact impedance of the circuit, avoid large errors in the resistance value collection of the heating element 120, and ensure the accuracy of the resistance value collection of the heating element 120.

[0041] See also Figure 1 More preferably, the outer wall of the receiving member 110 is provided with a strip block 111, which defines a strip groove 112. The first electrode 130 is inserted into the strip groove 112 along its length and is snap-fitted thereto. The length of the strip groove 112 is parallel to the length of the first electrode 130. The strip block 111 is slidably connected to the docking groove 220.

[0042] The strip groove 112 facilitates the installation and fixation of the first electrode 130 on the outer wall of the receiving member 110. Alternatively, the strip groove 112 can serve as a preliminary positioning limiter for the first electrode 130, thereby facilitating subsequent fixation of the first electrode 130 to the receiving member 110, such as by welding, to more securely fix the first electrode 130 to the receiving member 110. The strip groove 112 design also serves to store and protect the first electrode 130.

[0043] It can be understood that at this time, the docking groove 220, the wire loading cavity 230 and the strip block 111 are also configured as a pair, and the first electrode 130, the second electrode 210, the lead 140, the docking groove 220, the wire loading cavity 230 and the strip block 111 are all arranged in a one-to-one correspondence.

[0044] A snap-fit ​​structure is provided between the strip groove 112 and the first electrode 130 to limit axial movement of the first electrode 130 along the receiving member 110, while the strip groove 112 is used to limit radial movement of the first electrode 130 along the receiving member 110 through its groove wall. Alternatively, a guide portion 134 is provided at the end of the first electrode 130 to assist in inserting the first electrode 130 into the strip groove 112. For example, symmetrically distributed inclined surfaces are provided on both sides of the end of the first electrode 130 along its length. These symmetrically distributed inclined surfaces form a tapered structure at the end of the first electrode 130 to facilitate guiding.

[0045] For example, Figure 1 As shown, along the length direction of the strip block 111, opposite protrusions 113 are respectively provided on the side walls of the strip groove 112. Correspondingly, along the length direction of the first electrode 130, opposite grooves 131 are respectively provided on the side walls of the first electrode 130. The protrusions 113 and the grooves 131 cooperate with each other in a concave-convex manner to achieve a snap-fit ​​connection between the first electrode 130 and the strip groove 112. The positions and numbers of the protrusions 113 and the grooves 131 mentioned here are merely examples and should not be construed as limitations on the present application. In practice, the protrusions 113 and the grooves 131 can be flexibly arranged according to the requirements of the snap fit.

[0046] In order to realize that the strip groove 112 restricts the radial movement of the first electrode 130 along the receiving member 110 through the groove wall, for example, Figure 6As shown, the strip groove 112 includes a first groove 114 and a second groove 115 that are connected. The first groove 114 is located on the side close to the axis of the receiving member 110, and the second groove 115 is located on the side away from the axis of the receiving member 110. The strip-shaped first electrode 130 includes a first electrode strip 132 and a second electrode strip 133. The first electrode strip 132 is located on the side close to the axis of the receiving member 110, and the second electrode strip 133 is located on the side away from the axis of the receiving member 110. The first electrode strip 132 is inserted into the first groove 114, and the second electrode strip 133 is inserted into the second groove 115. The shape of the strip groove 112 is consistent with the shape of the first electrode 130, so that Figure 6 Taking the specific shape of the first electrode 130 as an example, the cross-section of the first electrode strip 132 is a sector with a central angle greater than 180°, and the cross-section of the second electrode strip 133 is rectangular or approximately rectangular. Accordingly, the second electrode strip 133 is a long, strip-shaped plate. In this case, the first electrode strip 132 cooperates with the first groove 114 to achieve radial positioning of the first electrode 130 by the groove 112. The structures and shapes of the first electrode 130 and the groove 112 are merely examples and should not be construed as limiting the present application. For example, the first electrode 130 may not distinguish between the first electrode strip 132 and the second electrode strip 133, and the entire first electrode 130 may have a cross-section that is a sector with a central angle greater than 180° or other shape that facilitates clamping. Correspondingly, the groove 112 may not distinguish between the first groove 114 and the second groove 115, and the cross-section of the groove 112 may have a sector with a central angle greater than 180°. It should be noted that the cross-sections referred to herein refer to surfaces perpendicular to the axis of the receiving member 110.

[0047] When the first electrode 130 is divided into the first electrode strips 132 and the second electrode strips 133 , corresponding buckle structures are provided on the sidewalls of the second electrode strips 133 and the sidewalls of the second groove 115 .

[0048] By setting a snap-fit ​​structure between the strip groove 112 and the first electrode 130, and the shapes of the first electrode 130 and the strip groove 112 being matched, the first electrode 130 can be fixed to the receiving piece 110 in a mechanical structure manner, and the assembly and fixation of the first electrode 130 on the receiving piece 110 can be facilitated.

[0049] See also Figure 6 The first electrode 130 has an arcuate surface 135 on the side facing the docking groove 220, and the arcuate surface 135 is recessed toward the side closer to the axis of the receiving member 110. Alternatively, the bottom of the docking groove 220 communicates with the wire loading cavity 230. The bracket 200 further includes a support member 240 disposed within the wire loading cavity 230 and configured to support and secure the second electrode 210.

[0050] The design of the curved surface 135 facilitates contact between the second electrode 210 and the first electrode 130. Furthermore, the recessed curved structure can also provide a certain position limiting effect on the second electrode 210, thereby ensuring the reliability of the connection between the second electrode 210 and the first electrode 130. When line contact between the second electrode 210 and the curved surface 135 is required, the central angle corresponding to the curved surface 135 can be smaller. When surface contact between the second electrode 210 and the curved surface 135 is required, the central angle corresponding to the curved surface 135 can be larger so that the curved surface 135 can wrap around a portion of the second electrode 210 for surface contact.

[0051] See also Figure 5 , a wiring cavity 230 is provided in the bracket 200, and the second electrode 210 is only installed in the wiring cavity 230. If there is no fixing or supporting structure, the second electrode 210 is not stably installed in the wiring cavity 230 and may shift, making it impossible for the second electrode 210 to be reliably connected to the first electrode 130. By providing a support member 240 in the wiring cavity 230, the support member 240 is used to support and fix the second electrode 210, thereby ensuring the position stability of the second electrode 210 and ensuring the reliable connection between the second electrode 210 and the first electrode 130. Specifically, for example Figure 7 As shown, the support member 240 is a support plate, and the second electrode 210 is bent into two sections. The longer section is placed in the wiring cavity 230, and the shorter section passes over the top of the support member 240 and is placed in the docking groove 220. At least a portion of the second electrode 210 placed in the docking groove 220 can be parallel to the first electrode 130, so that the second electrode 210 and the first electrode 130 can contact each other. More specifically, two spaced support holes are provided on the plate-shaped support member 240. One support hole is used to allow the second electrode 210 in the wiring cavity 230 to pass through and be placed in the docking groove 220, and the other support hole is used to allow the second electrode 210 in the docking groove 220 to pass back into the wiring cavity 230, so that a portion of the second electrode 210 exists in the docking groove 220. At this time, the second electrode 210 can be effectively supported and fixed by the plate-shaped support member 240 and the support holes.

[0052] See also Figure 8In other embodiments, the receiving member 110 includes an inner tube 116 and an outer tube 117 that are connected to each other. The outer tube 117 is sleeved on the outside of the inner tube 116, and an annular heat-insulating space is formed between the outer tube 117 and the inner tube 116. The heating element 120 is fixed to the inner tube 116, and the first electrode 130 is fixed to the outer wall of the outer tube 117. For example, the first electrode 130 is fixed to the outer wall of the outer tube 117. Correspondingly, a strip block 111 can also be provided on the outer wall of the outer tube 117, and a strip groove 112 is opened on the strip block 111. The first electrode 130 is inserted into the strip groove 112 along the length direction of the strip groove 112 and is snap-connected to the strip groove 112. The length direction of the strip groove 112 is parallel to the length direction of the first electrode 130. The strip block 111 is slidably connected to the docking groove 220.

[0053] In other embodiments, the first electrode 130, the second electrode 210, and the lead 140 can be arranged in multiple pairs. For example, the first electrode 130, the second electrode 210, and the lead 140 are all designed as two pairs. Taking the lead 140 as an example, one pair of the two pairs of lead 140 is used to electrically connect to the heating element 120, and the other pair is used to connect to other components, such as a temperature measuring element. The temperature measuring element is fixed to the heating element 120 and is used to measure the temperature of the heating element 120. The lead 140 connected to the temperature measuring element is connected to the control board through the corresponding first electrode 130 and the second electrode 210. In this way, the temperature measuring element can feed back the measured temperature to the control board to facilitate controlling the heating state of the heating element 120.

[0054] The heating structure is designed to heat the aerosol-forming substrate in conjunction with airflow. The airflow can be introduced from either the bottom or top of the container 110. The specific airflow method and structure can be designed based on actual needs and are not specifically limited in this application. The top of the container 110 is used to insert the aerosol-forming substrate into the container 110.

[0055] In another embodiment of the present application, an atomizer is provided, comprising a housing 300, a power supply 400, a control board (not shown) and the above-mentioned heating structure. The bracket 200 is fixed in the housing 300, and the second electrode 210 is connected to the first electrode 130 and the control board respectively. The power supply 400 is electrically connected to the heating element 120, and the power supply 400 is used to provide electrical energy to the heating element 120. The control board is electrically connected to the heating element 120 through the second electrode 210, the first electrode 130 and the lead 140. The control board is used to control the working state of the heating element 120, such as controlling the start or shut down of the heating element 120, the heating temperature of the heating element 120, etc. Among them, the bracket 200 and the housing 300 can be two independent structures or an integrated structure.

[0056] See also Figure 2 and Figure 9Specifically, a partition plate 310 is provided in the housing 300 to divide the space in the housing 300 into two along the axial direction of the housing 300, for example Figure 2 The heating structure is placed in the upper space of the middle shell 300, and the power supply 400 and the control board are placed in the lower space of the shell 300. The partition plate 310 is provided with an avoidance hole 311 that communicates with the wiring cavity 230 in the bracket 200. The second electrode 210 passes through the avoidance hole 311 to penetrate into the lower space of the shell 300 to facilitate electrical connection between the second electrode 210 and the control board. In other embodiments, the space within the shell 300 can be distributed in a left-right manner in addition to being distributed in an up-down manner. For example, the heating structure and the power supply structure are distributed in the shell 300 at intervals along the radial direction of the shell 300. The power supply structure includes components such as the power supply 400 and the control board. Among them, the direction perpendicular to the axial direction of the shell 300 is the radial direction of the shell 300.

[0057] See also Figure 2-Figure 3 In this embodiment of the present application, the atomizer further includes an end cap 500, which is detachably fixed to the end of the housing 300 and abuts against the receiving member 110. For example, the end cap 500 and the housing 300 are snap-fitted together, and the abutment between the end cap 500 and the receiving member 110 can limit the position of the heating component 100 in the bracket 200, ensuring the stable installation of the heating component 100 in the bracket 200.

[0058] More preferably, a positioning groove 250 is provided on the side of the bracket 200 facing the top cover, and a magnetic component 600 is placed in the positioning groove 250. The magnetic component 600 can be magnetically adsorbed to the end cover 500. For example, the magnetic component 600 is a magnet, and the end cover 500 is a magnetic metal. Alternatively, in order to ensure the strength of magnetic adsorption, a corresponding magnetic component 600 is also provided on the side of the end cover 500 facing the bracket 200. The magnetic component 600 on the bracket 200 and the magnetic component 600 on the end cover 500 are magnetically adsorbed to enhance the installation strength of the end cover 500 on the outer shell 300.

[0059] The above-mentioned atomizer is designed so that the heating component 100 and the bracket 200 are detachably connected, and the end cover 500 and the outer shell 300 are detachably connected. When the heating element 120 generates heat and fails, the heating component 100 in the bracket 200 can be removed and replaced by removing the end cover 500, thereby replacing the heating element 120. The rest of the atomizer can continue to be used, avoiding the phenomenon of the entire atomizer being scrapped. Based on the design that the heating component 100 can be disassembled on the atomizer, it is also possible to replace heating components 100 of different models or structures according to actual use requirements to meet different heating needs, achieve multi-purpose use of one machine, and bring better user experience to customers. For example, the heating component 100 containing heating elements 120 of different lengths can be replaced according to needs, or the heating component 100 with receiving parts 110 of different thicknesses or lengths can be replaced.
