Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and particularly to a battery device for an electronic cigarette and an electronic cigarette. Background Technology

[0002] In recent years, with people's increasing pursuit of a healthy life, e-cigarettes have become a relatively mature alternative to smoking on the market.

[0003] Battery-powered cigarettes mainly consist of a battery device and an atomizing device connected to the battery device. The battery device supplies power to the heating unit in the atomizing device, which heats the e-liquid or tobacco to produce smoke for the user to inhale.

[0004] Most e-cigarettes on the market currently use replaceable rechargeable batteries, but these are limited by the length of the battery housing. For the same model of e-cigarette, only one battery length can be used, preventing users from freely replacing batteries of different lengths. When users use different models of e-cigarettes, they may need to choose different battery types, increasing their costs and maintenance expenses, causing significant inconvenience and negatively impacting the user experience.

The inner wall surface of the second mating section is provided with an annular boss that mates with the annular groove. The width of the annular boss along the axial direction of the second receiving section is smaller than the width of the annular groove along the axial direction of the second receiving section. The battery tube includes a first receiving section and a second receiving section connected in sequence, wherein the outer diameter of the first receiving section is larger than the outer diameter of the second receiving section; the battery device of the electronic cigarette also includes a fixing ring, wherein the fixing ring includes a fixing section arranged in an annular shape and a stop section protruding from the inner wall surface of the fixing section and extending circumferentially along the fixing section, the fixing section is connected to the outer peripheral wall of the first receiving section, and the stop section is spaced apart from the second receiving section; the annular side plate includes an annular connecting portion extending between the second receiving section and the fixing section and an annular stop portion protruding from the outer peripheral wall of the annular connecting portion, wherein the annular stop portion is used to abut against the stop section to prevent the electrode cover from falling off the battery tube.

[0022] This invention proposes a battery device for an electronic cigarette; please refer to [link / reference]. Figures 1 to 6 , Figure 1 This is an assembly diagram of the first embodiment of the battery device for the electronic cigarette of the present invention. Figure 2 This is an assembly diagram of a second embodiment of the battery device for an electronic cigarette according to the present invention. Figure 3 This is an assembly diagram of a third embodiment of the battery device for an electronic cigarette according to the present invention. Figure 4 This is an assembly diagram of the fourth embodiment of the battery device for the electronic cigarette of the present invention; Figure 5 This is an assembly diagram of the fifth embodiment of the battery device for the electronic cigarette of the present invention; Figure 6 This is a schematic diagram of the sixth embodiment of the battery device for an electronic cigarette according to the present invention. The battery device 100 of the electronic cigarette includes a battery tube 10 and an electrode assembly 20; wherein, one end of the battery tube 10 is open and the other end is provided with a clearance hole 11, and the battery tube 10 is used for battery installation; the length of the electrode assembly 20 is adjustable, and the electrode assembly 20 is disposed through the clearance hole 11 to be electrically connected to the battery electrode corresponding to the battery installed in the battery tube 10.

[0023] The shape of the inner cavity of the battery tube 10 is adapted to the shape of the battery. For example, if the cross-section of the battery is circular, the cross-section of the inner cavity of the battery tube 10 is also circular; similarly, if the cross-section of the battery is square, the cross-section of the inner cavity of the battery tube 10 is also square. One end of the battery tube 10 is open, which facilitates the installation of the battery inside the battery tube 10. The other end of the battery is provided with a clearance hole 11. The diameter of the clearance hole 11 is smaller than that of the open end of the battery tube 10, which prevents the battery from sliding out from the end of the battery tube 10 with the clearance hole 11 when it is installed inside the battery tube 10.

[0024] The electrode assembly 20 is a conductive element, with one end electrically connected to the corresponding power electrode 61, and the other end passing through the clearance hole 11 and electrically connected to the battery electrode corresponding to the battery inside the battery tube 10. The length of the electrode assembly 20 is adjustable, and there are many types of adjustable length structures. For example, the electrode assembly 20 can be composed of two movably sleeved structural members, or it can be composed of a spring-like structural member, etc., which will not be listed here.

[0025] When electrically connecting the battery to the two power electrodes 61 on the electronic cigarette, first insert one end of the battery into the open end of the battery tube 10, and then pass one end of the electrode assembly 20 through the clearance hole 11 to electrically connect it to the battery electrode adjacent to the clearance hole 11. The length of the electrode assembly 20 can be adjusted according to the length of the battery so that the end of the battery away from the electrode assembly 20 can be exposed from the open end of the battery tube 10, while the end of the electrode assembly 20 away from the battery can protrude from the clearance hole 11. This ensures that when the battery, battery tube 10, and electrode assembly 20 are installed together between the two power electrodes 61 of the electronic cigarette, the battery is electrically connected to the two power electrodes 61 of the electronic cigarette. Since the length of the electrode assembly 20 extending into the battery tube 10 is adjustable, the battery device 100 of the electronic cigarette can be adapted to batteries of different lengths, making it convenient for users to replace the batteries of the electronic cigarette.

[0026] In one embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The electrode assembly 20 includes an adapter electrode 21 and a conductive rod 22. The adapter electrode 21 has a threaded hole 211. The conductive rod 22 includes a connecting section 221 that passes through a relief hole 11 and a threaded section 222 that connects to one end of the connecting section 221. The threaded section 222 is used for threaded connection with the threaded hole 211. With this configuration, the length of the entire electrode assembly 20 can be adjusted by adjusting the length of the threaded connection between the threaded section 222 on the conductive rod 22 and the threaded hole 211 on the adapter electrode 21. This facilitates the adjustment of the length of the electrode assembly 20, thereby allowing adjustment of the length of the electrode assembly 20 extending into the battery tube 10, and enabling the battery device 100 of the electronic cigarette to be compatible with batteries of different lengths.

[0027] Considering that the electrode assembly 20 not only needs to electrically connect the battery electrode at one end of the battery to the corresponding power electrode 61, but also needs to position the battery and the corresponding power electrode 61, in order to better position the battery and the corresponding power electrode 61, in one embodiment of the present invention, the electrode assembly 20 further includes an electrode cover 23. The electrode cover 23 includes an annular side plate 231 and an end plate 232 at one axial end of the annular side plate 231. The annular side plate 231 is sleeved on one end of the battery tube 10 that is provided with a clearance hole 11. The adapter electrode 21 is installed on the end plate 232 and passes through the end plate 232.

[0028] Since the annular side plate 231 of the electrode cover 23 is sleeved on the end of the battery tube 10 with the clearance hole 11, the position of the electrode cover 23 is constrained by the battery tube 10. At the same time, the conductive rod 22 is constrained by the hole wall of the clearance hole 11 in the circumference of the battery tube 10. This limits both the conductive rod 22 and the adapter electrode 21 in the circumference of the battery tube 10, thereby avoiding the problem of the electrode assembly 20 tilting due to unbalanced force, which would lead to unstable battery installation.

[0029] To facilitate adjustment of the length of the electrode assembly 20, in one embodiment of the present invention, please refer to... Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The cross-section of the clearance hole 11 is non-circular (e.g., square, oblong, triangular, etc.), and the shape of the cross-section of the connecting section 221 matches the shape of the clearance hole 11. Since the adapter electrode 21 is fixedly connected to the end plate 232, and the electrode cover 23 is sleeved on the end of the battery tube 10 with the clearance hole 11, and since the cross-section of the clearance hole 11 on the battery tube 10 is non-circular, the cross-sectional shape of the connecting section 221 matches the shape of the clearance hole 11. This allows the connecting section 221 to rotate with the battery tube 10 when the battery tube 10 is rotated. If the electrode cover 23 is constrained by an external force, the connecting section 221 can rotate relative to the adapter electrode 21. Since the connecting section 221 can freely pass through the clearance hole 11, the length of the conductive rod 22 extending into the battery tube 10 can be adjusted, thereby adjusting the overall length of the conductive rod 22 and the adapter electrode 21.

[0030] To facilitate the adjustment of the length of the electrode assembly 20, in another embodiment of the present invention, the wall of the relief hole 11 is recessed with a limiting groove (not shown) extending axially therein, and the outer peripheral wall of the connecting section 221 is protruded with a stop protrusion (not shown) that cooperates with the limiting groove. The length of the stop protrusion in the axial direction of the connecting section 221 is less than the length of the limiting groove in the axial direction of the relief hole 11. Because the stop protrusion on the connecting section 221 cooperates with the limiting groove on the wall of the relief hole 11, the connecting section 221 is limited in the circumferential direction of the relief hole 11. This allows the connecting section 221 to rotate together when the battery tube 10 is rotated. If the electrode cover 23 is constrained by an external force, the connecting section 221 can rotate relative to the adapter electrode 21. Since the length of the stop protrusion in the axial direction of the connecting section 221 is less than the length of the limiting groove in the axial direction of the relief hole 11, the connecting section 221 can move relative to the limiting groove along the axial direction of the relief hole 11. This also adjusts the length of the conductive rod 22 extending into the battery tube 10, thereby adjusting the overall length of the conductive rod 22 and the adapter electrode 21.

[0031] Obviously, other methods can also be used to adjust the length of the electrode assembly 20. In another embodiment of the present invention, the outer peripheral wall of the connecting segment 221 is recessed with a guide groove (not shown) extending along its axial direction, and the wall of the relief hole 11 is protruded with a stop protrusion (not shown) that cooperates with the guide groove. The length of the stop protrusion in the axial direction of the relief hole 11 is less than the length of the guide groove in the axial direction of the connecting segment 221. Because the guide groove on the connecting section 221 engages with the stop protrusion on the wall of the relief hole 11, the connecting section 221 is limited in the circumferential direction of the relief hole 11. This allows the connecting section 221 to rotate together when the battery tube 10 is rotated. If the electrode cover 23 is constrained by an external force, the connecting section 221 can rotate relative to the adapter electrode 21. Since the length of the stop protrusion in the axial direction of the relief hole 11 is less than the length of the guide groove in the axial direction of the connecting section 221, the connecting section 221 can move relative to the stop protrusion along the axial direction of the relief hole 11. This adjusts the length of the conductive rod 22 extending into the battery tube 10, thereby adjusting the overall length of the conductive rod 22 and the adapter electrode 21.

[0032] It is worth noting that when adjusting the relative positions between the adapter electrode 21 and the conductive rod 22, if the position of the conductive rod 22 or the adapter electrode 21 is unrestricted, the end of the conductive rod 22 furthest from the adapter electrode 21 may detach from the battery tube 10, thus preventing the conductive rod 22 from electrically connecting the battery to the power electrode 61. Therefore, in one embodiment of the present invention, please refer to... Figure 1The connecting section 221 has a stop protrusion 2211 on its outer peripheral wall away from the threaded section 222. The stop protrusion 2211 is used to abut against the periphery of the battery near the clearance hole 11 to limit the conductive rod 22. This arrangement ensures that a portion of the conductive rod 22 always extends into the battery tube 10, thereby ensuring that the conductive rod 22 can always be electrically connected to the battery electrode at the corresponding end of the battery.

[0033] Obviously, other methods can also be used to limit the conductive rod 22. In another embodiment of the present invention, please refer to... Figure 2 The connecting section 221 has a stop protrusion 2211 on its outer peripheral wall away from the threaded section 222. The end edge of the clearance hole 11 near the battery is recessed along the axial direction of the clearance hole 11, forming a stop groove 12 that mates with the stop protrusion 2211. With this configuration, the conductive rod 22 can also be limited by the cooperation of the stop groove 12 and the stop protrusion 2211, ensuring that the end of the conductive rod 22 that extends into the battery tube 10 always extends into the battery tube 10 and is electrically connected to the corresponding battery electrode.

[0034] It should be noted that the stop groove 12 can be an elongated groove extending along the axial direction of the relief hole 11, or it can be an annular groove extending circumferentially along the relief hole 11. No specific limitation is made here.

[0035] Of course, other methods can also be used to limit the conductive rod 22. In another embodiment of the present invention, please refer to... Figure 3 The connecting section 221 has a recessed groove 2212 extending axially on its outer peripheral wall; a stop boss 13 adjacent to the clearance hole 11 is provided on the outer wall of the battery tube 10, and the stop boss 13 has a mounting hole 131 extending radially through the battery tube 10; the battery device 100 of the electronic cigarette also includes a locking member 30, which passes through the mounting hole 131 and engages with the groove 2212. With this configuration, the conductive rod 22 can also be limited by the engagement of the locking member 30 and the groove 2212, ensuring that the end of the conductive rod 22 extending into the battery tube 10 always extends into the battery tube 10 and is electrically connected to the corresponding battery electrode.

[0036] It should be noted that the distance between the groove wall of the strip 2212 adjacent to the battery and the end of the conductive rod 22 adjacent to the battery should be equal to or greater than the distance between the wall of the mounting hole 131 adjacent to the battery and the end of the clearance hole 11 adjacent to the battery. This ensures that the end of the conductive rod 22 away from the adapter electrode 21 can always be exposed from the end of the clearance hole 11 adjacent to the battery, thereby ensuring that the conductive rod 22 can always be electrically connected to the battery electrode at the corresponding end of the battery.

[0037] It is worth noting that the conductive rod 22 can also be indirectly limited by limiting the electrode cover 23. In one embodiment of the present invention, please refer to... Figure 4 The battery tube 10 includes a first receiving section 15 and a second receiving section 16 connected in sequence. The outer diameter of the first receiving section 15 is larger than the outer diameter of the second receiving section 16. The outer peripheral wall of the second receiving section 16 is recessed with an annular groove 161 extending circumferentially and axially. The inner surface of the annular side plate 231 is stepped and has a first mating section 2311 that mates with the first receiving section 15 and a second mating section 2312 that mates with the outer peripheral wall of the second receiving section 16. The inner wall surface of the second mating section 2312 is provided with an annular boss 2312a that mates with the annular groove 161. The width of the annular boss 2312a along the axial direction of the second receiving section 16 is smaller than the width of the annular groove 161 along the axial direction of the second receiving section 16. This configuration allows the annular boss 2312a to move within the annular groove 161 along the axial direction of the second receiving section 16. However, the stroke of the annular boss 2312a is constrained by the annular groove 161, which also limits the movement of the annular side plate 231 relative to the battery tube 10. Since the adapter electrode 21 of the electrode assembly 20 is fixedly connected to the electrode cover 23, and the conductive rod 22 is connected to the adapter electrode 21, the position of the conductive rod 22 can be indirectly limited, thereby ensuring that the end of the connecting section 221 of the conductive rod 22 away from the threaded section 222 always extends into the battery tube 10.

[0038] It should be noted that the annular boss 2312a can be integrally formed with the second mating section 2312. The annular boss 2312a can also be fixedly installed on the inner wall of the second mating section 2312 by bonding, screw connection and other connection methods. Here, the specific formation of the annular boss 2312a is not limited.

[0039] Of course, the movement of the electrode cover 23 can also be limited in other ways. In another embodiment of the present invention, please refer to... Figure 5The battery tube 10 includes a first receiving section 15 and a second receiving section 16 connected in sequence. The outer diameter of the first receiving section 15 is larger than the outer diameter of the second receiving section 16. The battery device 100 of the electronic cigarette also includes a fixing ring 50. The fixing ring 50 includes a fixing section 51 arranged in an annular shape and a stop section 52 protruding from the inner wall surface of the fixing section 51 and extending circumferentially along the fixing section 51. The fixing section 51 is connected to the outer peripheral wall of the first receiving section 15, and the stop section 52 is spaced apart from the second receiving section 16. The annular side plate 231 includes an annular connecting portion 2313 extending between the second receiving section 16 and the fixing section 51 and an annular stop portion 2314 protruding from the outer peripheral wall of the annular connecting portion 2313. The annular stop portion 2314 is used to abut against the stop section 52 to prevent the annular side plate 231 from falling off between the fixing ring 50 and the second receiving section 16. This configuration also limits the movement of the annular side plate 231, which in turn limits the movement of the electrode cover 23, thus indirectly limiting the position of the conductive rod 22.

[0040] It is worth noting that the annular stop portion 2314 can be a complete annular structure extending circumferentially along the annular connecting portion 2313, or it can be an incomplete annular structure extending circumferentially along the annular connecting portion 2313. The specific structure of the annular stop portion 2314 is not limited here.

[0041] To facilitate finding the feel for aligning the battery tube 10, electrode assembly 20, and battery assembly with the battery main unit 60 during assembly, in one embodiment of the present invention, please refer to... Figures 1 to 7 The battery device 100 of the electronic cigarette also includes an elastic reset member 40. One end of the elastic reset member 40 abuts against the end of the battery tube 10 where all the clearance holes 11 are opened, and the other end of the elastic reset member 40 abuts against the end plate 232 of the electrode cover 23.

[0042] When the battery tube 10, electrode assembly 20, and battery assembly are not installed on the battery main unit 60, the end plate 232 of the electrode cover 23 is spaced apart from the end of the battery tube 10 with the clearance hole 11. At this time, the elastic reset member 40 is not subjected to external force and is in a stretched state to elastically support the end plate 232 of the electrode cover 23. When the battery tube 10, electrode assembly 20, and battery assembly are installed on the battery main unit 60, an external force needs to be applied to the electrode cover 23 to bring the electrode cover 23 and the battery tube 10 closer together. At this time, the elastic reset member 40 is compressed. Then, the pressure on the electrode cover 23 is released, and the electrode cover 23 is released. The elastic reset member 40 recovers its elastic deformation as the external force is released to elastically support the end plate 232 of the electrode cover 23, so that the adapter electrode 21 on the electrode assembly 20 is electrically connected to the power electrode 61. Since the electrode cover 23 has two different states before and after the battery is installed into the battery host 60, it is convenient for users to judge whether the battery is installed in place by the state of the electrode cover 23.

[0043] It should be noted that the elastic reset element 40 can be a spring, a spring sheet, a rubber block, etc., and no specific limitation is made here. Preferably, the elastic reset element 40 is a spring, which is sleeved and fitted with the conductive rod 22 and the adapter electrode 21. One end of the spring abuts against the end plate 232 of the electrode cover 23, and the other end abuts against the periphery of the relief hole 11. This arrangement can effectively prevent the spring from deforming radially due to external force, thereby preventing the spring from effectively elastically supporting the electrode cover 23.

[0044] Furthermore, one end of the battery tube 10 with the relief hole 11 has a protruding annular protrusion 14 that surrounds the relief hole 11. The annular protrusion 14 is sleeved and engaged with one end of the spring, which makes the spring more securely installed.

[0045] It should be noted that, in order to facilitate finding the feel when assembling the battery tube 10, electrode assembly 20, and battery assembly with the battery host 60, electromagnetic components can also be provided on the electrode cover 23 and the battery tube 10. Specifically, a first magnetic component (not shown) is provided on the end plate 232 of the electrode cover 23, and a second magnetic component (not shown) is provided on the end of the battery tube 10 where the clearance hole 11 is provided. The magnetism of the second magnetic component is repulsive to the magnetism of the first magnetic component, so that the first magnetic component and the second magnetic component repel each other. This can achieve the same effect as the above embodiment, and will not be elaborated further here.

[0046] To facilitate the secure installation of the battery, in one embodiment of the present invention, please refer to... Figures 1 to 8The battery device 100 of the electronic cigarette also includes a battery main unit 60, on which two power electrodes 61 are arranged at intervals. A battery tube 10 is installed between the two power electrodes 61, so that the battery electrode at one end of the battery installed inside it is exposed from its open end and electrically connected to the corresponding power electrode 61. The electrode assembly 20 is used to electrically connect the battery electrode at the other end of the battery to the corresponding power electrode 61.

[0047] The battery main unit 60 can have various shapes, such as cylindrical or rectangular, and will not be listed here. It can also be made of various materials, including resin, plastic, and alloy, and will not be listed here. Two power electrodes 61 are spaced apart on the battery main unit 60. These electrodes can be located at either end of the battery compartment or protrude from the outer surface of the battery main unit 60. The specific arrangement of the power electrodes 61 is not limited here. Preferably, the battery main unit 60 is C-shaped, thus placing the two power electrodes 61 at either end of the battery main unit 60.

[0048] It should also be noted that, please refer to Figure 8 The battery host 60 also includes a main control board 62, buttons 63, a display screen 64, and a connector 65. The main control board 62 is electrically connected to the two power electrodes 61. The display screen 64 and the connector 65 are both electrically connected to the main control board 62. The buttons 63 include a power switch and a function key. The power switch is used to control the opening or closing of the electronic cigarette's battery device 100. The function key can be used to adjust the power, temperature, and other parameters of the electronic cigarette's battery device 100. The display screen 64 is used to display the battery's charge, power, temperature, and other parameters. The connector 65 can be used for charging and also for data transmission.

[0049] Furthermore, in order to more securely mount the battery, battery tube 10 and electrode assembly 20 between the two power electrodes 61, the battery tube 10 is provided with an adjustment thread 17 on its outer peripheral wall near its open end; the battery device 100 of the electronic cigarette also includes an adjustment ring 70 connected to the adjustment thread 17, which can move relative to the battery tube 10 along the axial direction of the battery tube 10 to abut against the battery host 60.

[0050] When installing the battery onto the battery main unit 60, the adjusting ring 70 can be rotated to move it away from the electrode assembly 20 until it comes into contact with the battery main unit 60. This increases the contact area and locking force between the open end of the battery tube 10 and the battery main unit 60, preventing the battery from detaching from the electronic cigarette's battery device 100. Conversely, when removing the battery, the adjusting ring 70 can be adjusted towards the electrode assembly 20, creating a gap between the adjusting ring 70 and the battery main unit 60. This facilitates the separation of the battery tube 10 from the power electrode 61, making battery removal easier.

[0051] This invention proposes an electronic cigarette (not shown), which includes an atomizing device and a battery device. The specific structure of the battery device is as described in the above embodiments. Since this electronic cigarette adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
