Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery and an atomizing device. Background Technology

[0002] A battery is a cup, tank, or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. Batteries are simple in structure, easy to carry, and easy to charge and discharge. They are also less affected by external climate and temperature, and their performance is stable and reliable, playing a significant role in all aspects of modern life.

[0003] Battery covers typically have through holes, and sealing plugs are fitted into these holes to seal them. However, the sealing plugs currently installed on battery covers are prone to partially or even completely lifting up, thus failing to provide a proper seal. Utility Model Content

[0004] This application provides a battery and an atomizing device, the main purpose of which is to enhance the sealing effect between the sealing plug and the through hole on the battery cover.

[0005] According to a first aspect of this application, a battery is provided, comprising:

[0006] The battery casing has an assembly port;

[0007] A battery cover, fixed to the assembly port, the battery cover and the battery casing forming a sealed battery cavity, the battery cover having a through hole; and

[0008] The sealing plug has a convex ring on its side wall, which is used to abut against the side wall of the through hole. The sealing plug is an elastic sealing plug.

[0009] In one embodiment, the sealing plug has the convex ring on the sidewall between its two ends.

[0010] In one embodiment, a deformation gap is formed between the sidewall of the sealing plug without the convex ring and the through hole.

[0011] In one embodiment, the sidewall of the sealing plug is provided with a plurality of axially spaced protruding rings.

[0012] In one embodiment, the outer diameter of the different convex rings increases progressively from the side closer to the battery casing to the side farther away from the battery casing.

[0013] In one embodiment, a stop portion is provided on the side of the through hole near the battery casing, and the stop portion abuts against the sealing plug.

[0014] In one embodiment, the battery cover and the battery casing are detachably connected, and the battery cover has a disassembly part on its outer side, which is used to assist in disassembling the battery cover.

[0015] In one embodiment, the battery cover has the disassembly portion on one end face away from the battery casing, and the disassembly portion and the battery cover are rotatably connected.

[0016] In one embodiment, the battery is a rugged battery.

[0017] According to a second aspect of this application, an atomizing device is provided, including the aforementioned battery.

[0018] According to the battery in the above embodiment, a convex ring is provided on the side wall of the sealing plug. The convex ring abuts against the side wall of the through hole on the battery cover, thereby ensuring the sealing performance between the sealing plug and the through hole. Because the convex ring abuts against the side wall of the through hole, rather than the entire side wall of the sealing plug abutting against the side wall of the through hole, there is still a certain deformation space between the sealing plug and the through hole after the sealing plug is deformed under pressure. This prevents the sealing plug from deforming outwards, i.e., prevents the sealing plug from lifting up, thereby enhancing the sealing effect between the sealing plug and the through hole on the battery cover.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] Typically, the sealing plug on a battery cover abuts or is press-fitted with the inner wall of the through-hole on the battery cover through its entire side wall. When the entire side wall of the sealing plug abuts or is press-fitted with the inner wall of the through-hole, because there is no deformation gap between the sealing plug and the through-hole, the deformation of the sealing plug under pressure can only be released into other spaces, such as the outside. This can lead to partial or even complete warping of the sealing plug, affecting the seal between the sealing plug and the through-hole. Specifically, for example, strip-shaped or waist-shaped sealing plugs (where the shape of the through-hole matches the shape of the sealing plug) are more prone to warping on both sides when the sealing plug is deformed under pressure. This application optimizes the fit between the sealing plug and the through-hole to strengthen or improve the seal between them. The specific structure of the battery designed in this application is as follows:

[0032] Please see Figures 1-8 One embodiment of this application provides a battery, including: a battery casing 10, a battery cover 20, and a sealing plug 30.

[0033] The battery casing 10 is provided with an assembly port 11, and the battery cover 20 is fixed to the assembly port 11. The battery cover 20 and the battery casing 10 enclose a sealed battery cavity, which can be used to hold electrolyte solution.

[0034] The battery cover 20 has a through hole 21, and the outer wall of the sealing plug 30 has a protruding ring 31. The protruding ring 31 is used to abut against the side wall of the through hole 21. The sealing plug 30 is an elastic sealing plug.

[0035] In the battery described in the above embodiment, a protruding ring 31 is provided on the side wall of the sealing plug 30. The protruding ring 31 abuts against the side wall of the through hole 21 on the battery cover 20, thereby ensuring the sealing performance between the sealing plug 30 and the through hole 21. Because the protruding ring 31 abuts against the side wall of the through hole 21, rather than the entire side wall of the sealing plug 30 abutting against the side wall of the through hole 21, there is still a certain deformation space between the sealing plug 30 and the through hole 21 after the sealing plug 30 is deformed under pressure. This prevents the sealing plug 30 from deforming outwards, i.e., prevents the sealing plug 30 from warping, thereby enhancing the sealing effect between the sealing plug 30 and the through hole 21 on the battery cover 20.

[0036] Please see Figure 1 as well as Figures 6-8 The battery casing 10 has a cylindrical structure, and the opening of the battery casing 10 forms an assembly port 11. The outer shape of the battery cover 20 is adapted to the outer shape of the battery casing 10. For example, the battery casing 10 is cylindrical, and the battery cover 20 is disc-shaped or cylindrical.

[0037] The elastic sealing plug 30 is made of an elastic material, such as silicone or rubber. Specifically, the sealing plug 30 is a cylindrical solid block, and the through hole 21 is a matching circular hole. The cylindrical sealing plug 30 and the circular through hole 21 are matched to better ensure the sealing performance between the sealing plug 30 and the through hole 21. It can be understood that the sidewall of the sealing plug 30 refers to the outer sidewall of the sealing plug 30. In other embodiments, the sealing plug 30 can also be a non-solid cylindrical block with a groove in the middle or inside, or the sealing plug 30 can be other shapes, such as elliptical, prismatic, or other irregular shapes. The structure of the through hole 21 is matched with the sealing plug 30, so the shape corresponding to the through hole 21 will not be listed further.

[0038] Specifically, in some embodiments of this application, the battery is a rugged battery, such as a rugged lithium battery. A rugged battery is a battery that has undergone special processing and possesses three-proof functions: waterproof, dustproof, and shockproof (or drop-proof). This type of battery can maintain stability and reliability under harsh environmental conditions, and therefore is widely used in various industrial and military fields.

[0039] This application achieves a seal at the through hole 21 by providing a raised ring 31 on the side wall of the sealing plug 30, and by the abutting or interference fit between the raised ring 31 and the inner wall of the through hole 21. Furthermore, a certain deformation space exists between the sealing plug 30 and the through hole 21, ensuring the connection strength between them and thus guaranteeing the seal at the through hole 21. This effectively prevents external moisture from entering the battery cavity, thereby effectively ensuring the battery's waterproofness.

[0040] Please see Figure 4 The sealing plug 30 has a raised ring 31 on the side wall between its two axial ends, and the two axial sides of the raised ring 31 are connected to the other side walls of the sealing plug 30 (i.e., the side walls without the raised ring 31) by an arc transition. The raised ring 31 on the side wall between the two axial ends of the sealing plug 30 provides a certain deformation space on both axial sides of the raised ring 31. When the sealing plug 30 is deformed under pressure, it can deform within the through hole 21, avoiding the phenomenon of partial or complete warping of the sealing plug 30, and effectively ensuring the sealing performance of the connection between the sealing plug 30 and the through hole 21.

[0041] For a better option, please refer to Figure 2 A deformation gap D is formed between the side wall of the sealing plug 30 (without the protruding ring 31) and the inner wall of the through hole 21. This deformation gap D provides sufficient deformation space for the protruding ring 31, which abuts against or is in an interference fit with the inner wall of the through hole 21. This allows the protruding ring 31, after abutting against the through hole 21, to have some interference release space. In other words, the protruding ring 31 on the sealing plug 30 (and other sealing plugs 30) can be released through the deformation gap D. Simultaneously, this ensures the sealing performance between the sealing plug 30 and the through hole 21, thereby guaranteeing the battery's three-proof function.

[0042] In other embodiments, the sidewall of the sealing plug 30 is provided with a plurality of axially spaced protruding rings 31. For example, Figure 5 As shown, the outer wall of the sealing plug 30 is provided with two axially spaced protruding rings 31. The two protruding rings 31 divide the sealing plug 30 into three segments axially upwards, so that a deformation gap D can be formed on both sides of each protruding ring 31. This provides sufficient deformation release space for the protruding rings 31 and the sealing plug 30 near the protruding rings 31.

[0043] At this time, it is still based on Figure 5 For example, Figure 5In actual use, the lower side of the sealing plug 30 is closer to the battery casing 10. More preferably, the outer diameter of the different convex rings 31 increases progressively from the side closer to the battery casing 10 to the side farther away from the battery casing 10. In this way, when the sealing plug 30 is inserted into the through hole 21, the convex ring 31 with a relatively smaller radial dimension enters the through hole 21 first, and the convex ring 31 with a relatively larger radial dimension enters the through hole 21 subsequently. The multiple convex rings 31 with progressively larger radial dimensions can form a certain installation guide, which facilitates the assembly of the sealing plug 30 into the through hole 21.

[0044] The through-hole 21 on the battery cover 20, together with the sealing plug 30, also provides an explosion-proof function. The specific principle of the explosion-proof function is as follows: when the battery leaks or the internal pressure of the battery cavity becomes too high due to overheating, reaching a certain level (generally ≥ 2 atmospheres), the friction between the sealing plug 30 and the through-hole 21 on the battery cover 20 is insufficient to counteract the internal pressure of the battery. In this case, the sealing plug 30 will pop out from the through-hole 21 to release the internal pressure of the battery, thereby achieving the explosion-proof effect.

[0045] If the existing battery structure is used, the sealing plug 30 is pressurized or abutted against the inner wall of the through hole 21 on the battery cover 20 through the entire outer wall. In addition to the fact that the sealing plug 30 does not have enough deformation space in the through hole 21 when it is under pressure, it is easy to deform to the outside, resulting in the phenomenon that the sealing plug 30 is partially or even completely lifted. In addition, when the internal voltage of the battery is too high and the sealing plug 30 needs to be ejected for explosion prevention, the large contact area between the entire outer wall of the sealing plug 30 and the inner wall of the through hole 21 of the battery cover 20 will have a large friction force, making it difficult for the sealing plug 30 to be ejected and unable to perform the explosion prevention function in time.

[0046] Correspondingly, the battery designed in this application has a relatively smaller contact area between the sealing plug 30 on the battery cover 20 and the through hole 21. This allows the sealing plug 30 to not only perform a sealing effect or ensure a sealing effect, but also to more easily overcome friction and pop out when the internal air pressure of the battery is too high, thus performing an explosion-proof function. In other words, the safety of the designed battery is guaranteed.

[0047] The more raised rings 31 are provided on the side wall of the sealing plug 30, the greater the friction force when the sealing plug 30 and the through hole 21 abut, thus better ensuring the sealing effect between the sealing plug 30 and the through hole 21. However, it will also increase the difficulty for the sealing plug 30 to pop out of the through hole 21 during explosion-proof operations. The number or number of raised rings 31 on the sealing plug 30 can be set according to actual needs, and this application does not impose specific limitations.

[0048] In other embodiments, multiple continuous spiral convex rings 31 may be provided on the outer wall of the sealing plug 30, with adjacent convex rings 31 spaced apart.

[0049] Please see Figure 7 In some embodiments of this application, a stop portion 22 is provided in the side of the through hole 21 near the battery casing 10, and the stop portion 22 abuts against the sealing plug 30. Specifically, the stop portion 22 can be provided in the end of the through hole 21 near the battery casing 10, so that sufficient space can be left in the through hole 21 to assemble the sealing plug 30. The purpose of the stop portion 22 is to limit the position of the sealing plug 30 and prevent the sealing plug 30 from being overly inserted into the through hole 21, or even inserted into the battery casing 10. Based on the purpose of the stop portion 22, as long as the stop portion 22 can stop the sealing plug 30, it is acceptable. The specific structure of the stop portion 22 can be, for example, an annular plate or a radially convex block, etc. The specific form of the stop portion 22 is not limited in this application, as long as the stopping function of the stop portion 22 can be achieved.

[0050] Specifically, the battery cover 20 and the battery housing 10 are detachably connected. The outer side wall of the battery cover 20 near the battery has a thread-like or ring-like structure to ensure the sealing of the connection between the battery cover 20 and the battery housing 10.

[0051] To facilitate the removal of the battery cover 20, a disassembly / removal part 40 is provided on the outside of the battery cover 20. The disassembly / removal part 40 is used to assist in the removal of the battery cover 20. When it is necessary to remove the battery cover 20 from the battery housing 10, the disassembly / removal part 40 allows workers or other automated mechanical structures to easily apply force to quickly remove the battery cover 20, improving the removal efficiency of the battery cover 20. When it is necessary to install the battery cover 20 at the assembly port 11 of the battery housing 10, the disassembly / removal part 40 can also be used to apply force to quickly install the battery cover 20, improving the installation efficiency of the battery cover 20.

[0052] The battery cover 20 has a disassembly part 40 on the end face away from the battery case 10, and the disassembly part 40 and the battery cover 20 are rotatably connected.

[0053] For example, Figure 3 and Figure 8 As shown, an assembly groove 23 is formed on the end face of the battery cover 20 away from the battery casing 10. First mating holes 24 are formed on the two side walls of the assembly groove 23, and second mating holes 41 are formed on the corresponding disassembly / removal part 40. A rotating shaft 50 passes through the second mating hole 41 and inserts into the first mating hole 24 on the assembly groove 23 to rotatably connect the disassembly / removal part 40 to the battery cover 20. When the disassembly / removal part 40 is not in use, it can be temporarily stored in the assembly groove 23. When it is needed, the disassembly / removal part 40 can be rotated to remove it from the assembly groove 23.

[0054] The assembly slot 23 can temporarily store the disassembly part 40 that is rotatably connected to the battery cover 20, making the overall structure of the designed battery more compact and miniaturized, thereby enabling other products, including the battery, to be designed in a compact and miniaturized manner.

[0055] Specifically, assembly slot 23, such as Figure 3 and Figure 8 As shown, the assembly slot 23 is a semi-circular assembly slot, and the disassembly part 40 is similar to a semi-circular torsion ring. The size of the torsion ring and the assembly slot 23 are matched.

[0056] More preferably, a clearance 25 is provided on the outer wall of the assembly groove 23, and a corresponding operating part 42 is provided on the outer wall of the disassembly and assembly part 40. For example, a recessed groove-shaped clearance 25 is provided on the outer wall of the assembly groove 23, which facilitates the contact and force application between the operator's hand and the operating part 42 on the outer wall of the disassembly and assembly part 40, thereby rotating the disassembly and assembly part 40. The operating part 42 can be a groove-shaped structure, a protruding structure that increases friction, etc.

[0057] The battery in the above embodiments designed in this application only changes the sealing structure at the through hole 21 that performs the explosion-proof function. The sealing plug 30 is changed from an interference fit between the entire sidewall and the through hole 21 to a partial interference fit between the sealing plug 30 and the through hole 21. That is, through the interference fit between the convex ring 31 on the sealing plug 30 and the through hole 21, a deformation gap D is formed between the sidewall of the sealing plug 30 (where the convex ring 31 is not located) and the inner wall of the through hole 21. This allows the interference-fitted convex ring 31 to deform and fill the deformation gap D after the sealing plug 30 is installed at the through hole 21, preventing defects such as warping. This maintains the sealing performance while retaining the explosion-proof function. The designed battery has a simple structure, is easy to assemble, and can maintain or reduce costs.

[0058] Another embodiment of this application provides an atomizing device, including an atomizer and a power supply module. The power supply module includes a battery and a control board. The battery provides electrical energy to the atomizer, and the control board controls the operating state of the atomizer. The atomizer heats the atomized aerosol to form a matrix or liquid to be atomized to produce an aerosol that can be inhaled by a user. The battery is the one designed in the above embodiment. Since the atomizer and power supply module are not the focus of this application, they will not be described in detail here.

[0059] The atomizing device provided in this application embodiment contains the battery in the above embodiment, and therefore also has the advantages of the battery in the above embodiment, so it will not be described in detail here.

[0060] The battery in the above embodiments designed in this application can be used not only in atomizers, but also in other products, such as watches, waterproof cameras, etc., which will not be listed here.

[0061] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
