[0033] The present application discloses a power supply assembly, which is applied to an aerosol generating device, such as an electronic cigarette, to power an atomizing assembly in the aerosol generating device.

[0034] Please refer to Figures 1 to 5. The power supply assembly of the present application is used to be installed in the cylinder 1 of the aerosol generating device and is sealed with the cylinder 1. The power supply assembly includes a battery cell 2, a control module and a first bracket 4. The battery cell 2 has a battery cell tab 21 located at one end of its length direction, and the battery cell tab 21 includes a positive tab and a negative tab; the control module includes a first circuit board 31 and a connecting electrode 32. The connecting electrode 32 is installed on the first circuit board 31 and is electrically connected to the first circuit board 31. The first circuit board 31 has a tab connection hole that is inserted into the battery cell tab 21 to achieve electrical connection; the connecting electrode 32 and the battery cell tab 21 are respectively located on both sides of the first circuit board 31; the first bracket 4 is located on one side of the battery cell 2 in the length direction of the battery cell 2, and the first bracket 4 has a through hole that is inserted into the connecting electrode 32. In this way, no wires are required in the entire power supply assembly, which helps to reduce line loss and facilitates the battery cell 2, the control module and the first bracket 4 to form a modular structure. During the assembly process of the power supply assembly and the aerosol generating device, it helps to achieve automated assembly, thereby improving the production efficiency of the entire aerosol generating device.

[0035] Specifically, in one embodiment, please refer to Figures 2 and 5, the battery cell 2 includes a battery cell body and a positive electrode tab and a negative electrode tab connected to the battery cell body. The battery cell body is a cylinder, and the battery cell body has a first end 22 and a second end 23 in its length direction. The positive electrode tab and the negative electrode tab are both connected to the first end 22 of the battery cell body; the battery cell 2 is fitted into the tab connection hole on the first circuit board 31 through the battery cell tab 21 located at the same end in its length direction, and the battery cell tab 21 is also welded to the first circuit board 31 to simultaneously achieve fixed connection and electrical connection between the battery cell tab 21 and the first circuit board 31.

[0036] The connecting electrode 32 and the battery cell 2 are located on either side of the first circuit board 31, respectively. The connecting electrode 32 includes a positive electrode and a negative electrode. The connecting electrode 32 is mounted on the first circuit board 31 and electrically connected to the first circuit board 31. The connecting electrode 32 can be inserted and mated with the first circuit board 31 and then welded to the first circuit board 31 to achieve both a fixed connection and an electrical connection with the first circuit board 31. The connecting electrode 32 is also used to electrically connect to the atomizer assembly in the aerosol generating device. In this way, the battery cell 2 is electrically connected to the atomizer assembly through the battery cell tab 21, the first circuit board 31, and the connecting electrode 32, thereby providing power to the atomizer assembly.

[0037] Of course, in other embodiments, the battery cell body may also be a rectangular parallelepiped, and the positive electrode tab and the negative electrode tab are connected to the same end in the length direction of the battery cell body.

[0038] In one embodiment, the first bracket 4 further includes a retaining structure that cooperates with the first circuit board 31 and is used to prevent the connection electrode 32 from being dislodged from the through-hole. This ensures relative fixation between the first bracket 4 and the first circuit board 31, enabling integrated assembly of the battery cell 2, control module, and first bracket 4, facilitating automated assembly of the power supply assembly and improving production efficiency.

[0039] Specifically, please continue to refer to Figures 2 and 5. The first bracket 4 is generally a cylindrical structure with one end open and the other end closed. A receiving groove for accommodating the first circuit board 31 is formed inside the cylindrical structure of the first bracket 4. A through hole is provided on the bottom wall of the receiving groove, and the through hole is used to be plugged into and matched with the connecting electrode 32 installed on the first circuit board 31; a sinking groove 41 is also provided on the bottom wall of the receiving groove, and the notch direction of the sinking groove 41 is opposite to the notch direction of the receiving groove. The number and position of the sinking grooves 41 correspond to the through hole, and a conductive ring 33 is installed in the sinking groove 41. The conductive ring 33 is also used to cooperate with the connecting electrode 32 to realize the electrical connection between the connecting electrode 32 and the atomization component.

[0040] A limiting structure can be provided on the side wall of the accommodating groove, and the first circuit board 31 can be interference fit with the side wall of the accommodating groove on the first bracket 4, so as to limit the first circuit board 31 from escaping from the accommodating groove through interference fit, that is, to limit the connecting electrode 32 from escaping from the through hole, so that the part on the side wall of the accommodating groove used for interference fit with the first circuit board 31 forms a limiting structure.

[0041] In one embodiment, please refer to Figure 5, the limiting structure includes a protrusion 42 arranged on the side wall of the accommodating groove and extending toward the accommodating groove, and the protrusion 42 is located on the side of the first circuit board 31 facing the battery cell 2 in the length direction of the battery cell 2, and the protrusion 42 and the first circuit board 31 are abutted against each other in the length direction of the battery cell 2. An opening 43 connected to the accommodating groove is provided on the side wall of the accommodating groove, and the protrusion 42 is provided on the side of the opening 43 facing away from the accommodating groove, so as to facilitate the injection molding of the first bracket 4; the protrusion 42 has a first side surface 421 facing the bottom wall of the accommodating groove in the length direction of the battery cell 2 and a second side surface 422 facing away from the bottom wall of the accommodating groove, the first side surface 421 is perpendicular to the length direction of the battery cell 2, and the angle between the second side surface 422 and the first side surface 421 is less than 90°; in the process of the first circuit board 31 being installed into the accommodating groove, the second side surface 422 can provide guidance for the first circuit board 31 to facilitate the installation of the first circuit board 31 in the accommodating groove. After the first circuit board 31 is installed in the accommodating groove, the first circuit board 31 and the first side surface 421 of the protrusion 42 are abutted against each other in the length direction of the battery cell 2 to limit the first circuit board 31 from escaping from the accommodating groove, that is, to limit the connecting electrode 32 from escaping from the through hole.

[0042] Of course, in some other embodiments, the limiting structure can also be formed by the wall surface of the through hole on the first bracket 4, and the diameter of the through hole is equal to or slightly smaller than the outer diameter of the connecting electrode 32, so that the connecting electrode 32 and the through hole on the first bracket 4 have an interference fit to limit the connecting electrode 32 from escaping from the through hole.

[0043] In one embodiment, the power supply assembly further includes an insulating bracket 5, which is located between the first circuit board 31 and the battery cell 2. Referring to Figures 2 and 5, the insulating bracket 5 is generally annular in structure. The battery cell tab 21 passes through the insulating bracket 5 and is then plugged into the first circuit board 31. The insulating bracket 5 is provided with mounting posts 51 on the side facing the first circuit board 31. There are three mounting posts 51, which are spaced apart from each other. The mounting posts 51 engage with corresponding sockets on the first circuit board 31 to achieve relative positioning of the insulating bracket 5 and the first circuit board 31 in a plane perpendicular to the length of the battery cell. In the length direction of the battery cell, the insulating bracket 5 is press-fitted between the battery cell 2 and the first circuit board 31, separating the outer shell of the battery cell 2 from the first circuit board 31 through the insulating bracket 5 to prevent a short circuit between the outer shell of the battery cell 2 and the first circuit board 31.

[0044] Of course, in some other embodiments, the insulating bracket 5 may not be provided. For example, insulating glue may be applied to the end face of the battery cell 2 provided with the battery cell tab 21 to ensure insulation between the battery cell 2 shell and the first circuit board 31 through the insulating glue. In addition, the structure of sealing the end face of the battery cell 2 with insulating glue also helps to ensure the safety performance of the entire battery cell 2. For example, the elastic deformation ability of the insulating glue can be used to prevent the internal pressure of the battery cell 2 from being too high, which may cause the battery cell 2 to explode or the internal material to leak out.

[0045] In some embodiments, the power supply assembly also includes a second bracket 6, which is fixedly connected to the first bracket 4. The second bracket 6 has a supporting portion, which is located on the side of the battery cell 2 facing away from the first circuit board 31 in the length direction of the battery cell 2. The supporting portion can be supported by the battery cell 2 in the length direction of the battery cell 2 to limit the displacement of the battery cell 2 in the length direction of the battery cell 2.

[0046] Please refer to Figures 2, 3 and 5. The second bracket 6 extends in the length direction of the battery cell 2. The second bracket 6 has a supporting end 61 away from the first bracket 4 and a connecting end 62 close to the first bracket 4 in the length direction of the battery cell 2. The supporting end 61 is located on the side of the battery cell 2 facing away from the first circuit board 31 in the length direction of the battery cell 2. The supporting portion is provided at the supporting end 61. The structure of the supporting portion may not be limited. For example, the supporting portion may include a bump, a rib or other structure protruding toward the central axis of the battery cell 2. The positive projection of the supporting portion on the end face of the second end 23 of the battery cell 2 is located on the end face of the second end 23 of the battery cell 2. In this way, the supporting portion can be supported by the end face of the second end 23 of the battery cell 2 in the length direction of the battery cell 2 to limit the displacement of the battery cell 2 in its length direction and prevent the battery cell 2 from separating from the first circuit board 31.

[0047] The second bracket 6 is fixedly connected to the first bracket 4 via a connection end 62. For example, the connection end 62 of the second bracket 6 has a cantilever arm 621 extending toward the first bracket 4 in the lengthwise direction of the battery cell 2. Multiple cantilever arms 621 are provided and spaced apart around the battery cell 2. A latch is provided on one of the cantilever arms 621 and the first bracket 4, and a hook 622 is provided on the other. The latch and hook 622 engage to securely connect the first bracket 4 to the second bracket 6. This eliminates the need for additional components, facilitates assembly of the first bracket 4 and the second bracket 6, and facilitates automated assembly of the power supply assembly and the entire aerosol generating device. Please refer to Figures 2 and 5. The bayonet is set on the first bracket 4, and the opening 43 on the side wall of the accommodating groove on the first bracket 4 forms a bayonet. The hook 622 is set on the second bracket 6, and the hook 622 is located at the free end of the cantilever arm 621 of the second bracket 6; during the assembly of the first bracket 4 and the second bracket 6, the cantilever arm 621 is deformed away from the battery cell in the longitudinal direction perpendicular to the battery cell 2, so that the hook 622 cooperates with the opening 43 on the first bracket 4 from the outside of the first bracket 4 to achieve a fixed connection between the first bracket 4 and the second bracket 6.

[0048] Of course, in some other embodiments, the bayonet may be provided on the second bracket 6, and the hook 622 may be provided on the first bracket 4. Alternatively, in other embodiments, the second bracket 6 may be inserted into the first bracket 4, and the second bracket 6 and the first bracket 4 may be interference fit to achieve a fixed connection between the first bracket 4 and the second bracket 6.

[0049] In some embodiments, please continue to refer to Figures 2, 3 and 5. The second bracket 6 includes an axial end portion 63 and a peripheral portion 64 arranged in the length direction of the battery cell 2. The axial end portion 63 is installed on the end of the peripheral portion 64 facing away from the first bracket 4 in the length direction of the battery cell 2. The peripheral portion 64 includes an annular portion 641 and an arc portion 642. The annular portion 641 is connected to the side of the arc portion 642 facing away from the first bracket 4 in the length direction of the battery cell 2. The annular portion 641 is an annular cylindrical structure extending in the length direction of the battery cell 2. The arc portion 642 is in the length direction of the battery cell 2. The arcuate portion 642 extends upward, and the radial dimension of the annular portion 641 is the same as that of the annular portion 641. The annular portion 641 has an opening facing the axial end portion 63. The axial end portion 63 is inserted into the opening of the peripheral portion 64 and is engaged with the notch 645 via a raised hook 633. The raised hook 633 can be provided on the outer peripheral surface of the axial end portion 63, and the notch 645 can be provided on the side wall of the annular portion 641. Alternatively, in other embodiments, the axial end portion 63 can be inserted into the opening of the peripheral portion 64 and have an interference fit to facilitate assembly of the second bracket 6 and facilitate automated assembly. Alternatively, in some other embodiments, the second bracket 6 can be an integrally molded structure to facilitate processing and manufacturing of the second bracket 6.

[0050] On the second bracket 6, the annular portion 641 of the outer peripheral portion 64 is located on the side of the battery cell 2 away from the control module in the length direction of the battery cell 2. The annular portion 641 of the outer peripheral portion 64 and the axial end portion 63 form the supporting end 61 of the entire second bracket 6, and the connecting end 62 is arranged on the arc portion 642 of the outer peripheral portion 64.

[0051] Of course, in some other embodiments, the outer peripheral portion 64 of the second bracket 6 is formed as a whole into a cylindrical structure extending in the length direction of the battery cell 2, one end of which is open and connected to the axial end 63, and the other end is a connecting end 62 connected to the first bracket 4.

[0052] In some embodiments, in the longitudinal direction perpendicular to the battery cell 2, grooves 7 are provided on the outer side surface of the first bracket 4 facing away from the battery cell 2 and the outer side surface of the second bracket 6 facing away from the battery cell 2. The extension direction of the groove 7 is perpendicular to the longitudinal direction of the battery cell 2. There are multiple grooves 7, and the multiple grooves 7 are arranged at intervals in the longitudinal direction of the battery cell 2.

[0053] Please refer to Figures 2 and 3. The outer side surface of the second bracket 6 facing away from the battery cell 2 includes the circumferential outer surface of the annular portion 641 and the outer side surface of the arc portion 642 facing away from the battery cell 2. The central angle corresponding to the arc portion 642 is 180°. Grooves 7 are provided on the outer side surface of the arc portion 642 facing away from the battery cell 2, the circumferential outer surface of the annular portion 641, and the outer groove wall surface of the first bracket 4. The grooves 7 extend in the circumferential direction of the second bracket 6. Since the multiple grooves 7 are arranged at intervals in the length direction of the battery cell 2, the multiple grooves 7 can form an oil-blocking structure to prevent the tobacco oil in the electronic cigarette from leaking out from the assembly gap between the barrel 1 and the power supply component along the length direction of the battery cell 2 in the barrel 1.

[0054] Of course, in some other embodiments, the groove 7 may not be provided on either the first bracket 4 or the second bracket 6, and a sealing structure, such as a sealing ring 10, may be provided between the first bracket 4 and the barrel 1 or between the second bracket 6 and the barrel 1 to prevent the e-liquid from moving within the barrel 1 toward the battery cell 2. Alternatively, in other embodiments, the groove 7 may be provided only on the first bracket 4 or the second bracket 6 to form an oil-blocking structure.

[0055] In some embodiments, the power supply assembly further includes a charging module, which is located on a side of the battery cell 2 facing away from the control module along the length of the battery cell 2 and is fixedly connected to the second bracket 6. The charging module includes a second circuit board 81 and a charging connector 82. The second circuit board 81 is electrically connected to the first circuit board 31. The charging connector 82 is mounted on and electrically connected to the second circuit board 81.

[0056] Referring to Figures 2, 4, and 5, the first circuit board 31 in the control module and the second circuit board 81 in the charging module are located on either side of the battery cell 2 along its length. The first circuit board 31 and the second circuit board 81 are arranged parallel to each other and are electrically connected via a wire. The central axis of the battery cell 2 does not coincide with the central axis of the second bracket 6. In a plane perpendicular to the length of the battery cell 2, the central axis of the battery cell 2 is located on the side of the central axis of the second bracket 6 facing away from the curved portion 642. This creates a space between the curved portion 642 of the second bracket 6 and the circumferential outer wall of the battery cell 2. This space allows for the wires connecting the first circuit board 31 and the second circuit board 81 to pass through, thereby facilitating the conductive connection between the first circuit board 31 and the second circuit board 81.

[0057] The charging module is fixedly connected to the second bracket 6 , and may be one or both of the second circuit board 81 and the charging connector 82 fixedly connected to the second bracket 6 , and the charging connector 82 is also mounted on the second circuit board 81 .

[0058] In some embodiments, please refer to Figures 2 and 4, the axial end 63 of the second bracket 6 is provided with an end opening 631, and the end opening 631 is used to be plugged into and matched with the charging connector 82 to form a charging interface. The side wall of the end opening 631 can be interference fit with the charging connector 82 or the side wall of the end opening 631 can be connected to the charging connector 82 by a snap-fit ​​to achieve a fixed connection between the charging connector 82 and the second bracket 6.

[0059] In other embodiments, referring to Figures 2 and 5 , during the assembly process of the axial end portion 63 and the peripheral portion 64, the second circuit board 81 can be press-fitted and fixed between the axial end portion 63 and the peripheral portion 64. The axial end portion 63 has a first end surface 632 facing the cell 2 along the length of the cell 2. The first end surface 632 can be the axial outer end surface of the axial end portion 63 for inserting and mating with the peripheral portion 64. The peripheral portion 64 has a second end surface 644 facing away from the cell 2 along the length of the cell 2. The opening sidewall of the annular portion 641 of the peripheral portion 64 is provided with a first protrusion 643 protruding radially inward. The second end surface 644 is the side surface of the first protrusion 643 facing away from the cell 2 along the length of the cell 2. The second circuit board 81 is press-fitted and fixed between the first end surface 632 and the second end surface 644 to achieve a fixed connection between the second fixing plate and the second bracket 6. This fixed connection method is convenient to operate and facilitates the automated assembly of the power supply assembly.

[0060] Of course, in some other embodiments, the second circuit board 81 may also be interference fit with the opening side wall of the upper peripheral portion 64 of the second bracket 6 to achieve a fixed connection between the second circuit board 81 and the second bracket 6 .

[0061] In some embodiments, the first protrusion 643 provided on the side wall of the opening of the outer peripheral portion 64 forms an abutting portion, and the first protrusion 643 abuts against the battery cell 2 in the length direction of the battery cell 2. Alternatively, in other embodiments, part of the side wall of the annular portion 641 in the outer peripheral portion 64 forms an abutting portion for abutting against the battery cell 2 in the length direction of the battery cell 2.

[0062] The present application also discloses an aerosol generating device, which includes a barrel 1, an atomizing assembly (not shown in the figure) and a power supply assembly in any of the above embodiments. The barrel 1 is a cylindrical structure with openings at both ends. The atomizing assembly and the power supply assembly are both installed in the barrel 1 and arranged in the length direction of the barrel 1. The power supply assembly is sealed with the barrel 1 through a sealing ring 10 installed on the outer peripheral surface of the first bracket 4; the power supply assembly is electrically connected to the atomizing assembly through a connecting electrode 32 to provide power to the atomizing assembly.

[0063] The first bracket 4 has a positioning guide structure, which can realize the positioning and conductive connection between the atomizing assembly and the connecting electrode 32. Specifically, in one embodiment, please refer to Figure 2, the two sink grooves 41 on the first bracket 4 are spaced apart in the radial direction of the first bracket 4, and a positioning column 44 is further provided at one end of the first bracket 4 where the sink groove 41 is provided. There are two positioning columns 44, and the two positioning columns 44 are also spaced apart in the radial direction of the first bracket 4, and the arrangement direction of the two positioning columns 44 is perpendicular to the arrangement direction of the two sink grooves 41. The two positioning columns 44 protrude from the end face of the first bracket 4, and the positioning columns 44 are used to position and cooperate with the positioning groove on the atomizing assembly to ensure that the connecting electrode 32 is accurately electrically connected to the atomizing assembly; and the positioning column 44 is generally a cylindrical structure, and the outer peripheral surface of the positioning column 44 is an inclined surface. The outer peripheral surface of the positioning column 44 can provide a guide for the insertion of the positioning column 44 and the positioning groove, so that the positioning column 44 forms a positioning guide structure that realizes the positioning and conductive connection between the connecting electrode 32 and the atomizing assembly.

[0064] In another embodiment, the structure of the positioning column 44 on the first bracket 4 can be eliminated, and the positioning guide structure includes two magnetic blocks installed on the first bracket 4. The magnetic blocks can be embedded in the first bracket 4 or can be integrally formed with the first bracket 4 by plastic wrapping; the two magnetic blocks and the sink groove 41 are arranged at the same end of the first bracket 4, and the two magnetic blocks are arranged at intervals in the radial direction of the first bracket 4, and the arrangement direction of the two magnetic blocks is perpendicular to the arrangement direction of the two sink grooves 41; two magnetic blocks are also arranged on the corresponding atomization component, and the magnetic attraction between the two magnetic blocks on the atomization component and the two magnetic blocks on the first bracket 4 is used to realize the positioning conductive connection between the two connecting electrodes 32 and the atomization component.

[0065] The control module of the power supply assembly also includes a switch element, which is mounted on the first circuit board 31 and is used to control the electrical connection between the battery cell tab 21 and the atomizer assembly. The switch element can be a microphone 91, which is fixedly mounted on the first circuit board 31. The first bracket 4 is provided with a bypass groove, and the bottom wall of the bypass groove is provided with a vent. The microphone 91 is located in the bypass groove. The microphone 91 is also equipped with a silicone sleeve 92, and the silicone sleeve 92 is also provided with air holes. The air holes are directly opposite the sensing diaphragm of the microphone 91, and the air holes are also corresponding to the air holes. In this way, the sensing diaphragm can be deformed by the pressure passing through the air holes and the space connected by the air holes, thereby controlling the electrical connection between the battery cell tab 21 and the atomizer assembly through the first circuit board 31. The structure of providing the silicone sleeve 92 on the microphone 91 and the air holes on the silicone sleeve 92 helps to improve the sensitivity of the switch element, enabling the microphone 91 to control the operation of the atomizer assembly under the action of a smaller suction force, which helps to improve the user experience.
