[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore only examples, and should not be used to limit the scope of protection of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0032] One embodiment of this application provides a flexible connection structure and an electronic atomizing device. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The elastic connection structure includes an elastic element 10 and a connecting electrode 20.

[0033] The elastic element 10 is made of shape memory metal. The elastic element 10 includes a bending portion 11 and an electrical connection portion 12. At least one end of the bending portion 11 is provided with the electrical connection portion 12.

[0034] The connecting electrode 20 has at least one mounting space, and the electrical connection part 12 is welded to the mounting space in a one-to-one correspondence.

[0035] Specifically, the elastic element 10 refers to a component that can withstand the force and produce corresponding deformation, and can return to its original shape after the external force disappears.

[0036] The elastic element 10 is made of shape memory metal. When an electric current passes through the elastic element 10, heat is generated. When the generated heat reaches the phase transformation point of the shape memory metal elastic element 10, the metallographic structure inside the elastic element 10 transforms from martensite to austenite, thereby causing the elastic element 10 to elongate. When the temperature returns to normal, the elastic element 10 returns to its original shape.

[0037] The connecting electrode 20 refers to the component that is electrically connected to the power source so that current can pass through the elastic element 10.

[0038] The material of the connecting electrode 20 is not limited, as long as it allows current to pass through. For example, the material of the connecting electrode 20 can be copper, aluminum, or a special alloy, which can improve the conductivity and corrosion resistance of the connecting electrode 20.

[0039] The provision of an electrical connection portion 12 at at least one end of the bent portion 11 means that the electrical connection portion 12 may be provided at only one end of the bent portion 11, or the electrical connection portion 12 may be provided at both opposite ends of the bent portion 11.

[0040] The installation space refers to the space on the connecting electrode 20 used to accommodate and fix the electrical connection part 12, ensuring that the electrical connection part 12 can stably form an electrical connection with the connecting electrode 20.

[0041] The fact that the connecting electrode 20 has at least one mounting space means that the mounting space on the connecting electrode 20 can be set to one or more as needed to accommodate different connection requirements.

[0042] The electrical connection part 12 corresponds to the installation space one by one, and the electrical connection part 12 is installed in the installation space by welding.

[0043] The welding method between the electrical connection part 12 and the connecting electrode 20 is not limited, as long as the electrical connection part 12 can be welded into the mounting space of the connecting electrode 20. For example, the electrical connection part 12 and the connecting electrode 20 can be soldered together.

[0044] Another embodiment of this application provides an electronic atomizing device; please refer to [link / reference]. Figure 4 The electronic atomizing device includes a flexible connection structure. This ensures the reliability of the electronic atomizing device in use.

[0045] The electrical connection methods for shape memory metal elastic components in related technologies mainly include die-casting riveting, clamp connection, and grinding connection, among which:

[0046] 1. Die-casting riveting refers to the die-casting and riveting of the two ends of a shape memory metal elastic component to form a stable electrical contact. However, this connection method is difficult to implement on extremely small shape memory metal elastic components. Furthermore, the metal material used in die casting has low conductivity, so a layer of high-conductivity material needs to be electroplated onto its surface to reduce contact resistance. This results in higher costs and increases the electrode size, making it unsuitable for applications in size-constrained electronic products.

[0047] 2. Clip-on connection refers to using electrodes with clips to hold the two ends of a shape memory metal elastic element to achieve an electrical connection. However, this connection method may have issues with inaccurate dimensional control and is relatively inconvenient to operate. The relatively large size of clip-on electrodes may limit their applicability in certain application scenarios.

[0048] 3. Grinding connection refers to grinding both ends of the shape memory metal elastic element flat and directly connecting it to the metal electrode to ensure good conductivity. However, this connection method is prone to unstable contact resistance, thus affecting the performance of the shape memory metal elastic element.

[0049] This application provides an elastic connection structure and an electronic atomizing device. The elastic connection structure includes an elastic element 10 and a connecting electrode 20. The elastic element 10 is made of shape memory metal and includes a bending portion 11 and an electrical connection portion 12. At least one end of the bending portion 11 is provided with the electrical connection portion 12. The connecting electrode 20 has at least one mounting space, and the electrical connection portions 12 are welded one-to-one into the mounting space. This simplifies the operation process; simply placing the electrical connection portion 12 in the mounting space and welding it achieves the connection between the elastic element 10 and the connecting electrode 20. Furthermore, the welding connection method effectively ensures the stability of the electrical connection between the elastic element 10 and the connecting electrode 20.

[0050] In one embodiment, please refer to Figure 2 The installation space includes a connection hole 23a, and the connection electrode 20 includes a connection plate 23 with a connection hole 23a. The electrical connection part 12 passes through the connection hole 23a. Therefore, by having the electrical connection part 12 pass through the connection hole 23a, the stability of the electrical connection can be ensured, and the occurrence of poor contact can be reduced.

[0051] Specifically, the connection hole 23a refers to the hole in the mounting space of the connecting electrode 20 for the electrical connection part 12 to pass through, and the electrical connection part 12 is electrically connected to the conductive structure inside the connecting electrode 20 through the connection hole 23a.

[0052] The shape and size of the connecting hole 23a are not limited, as long as the electrical connection part 12 can pass through.

[0053] The connecting plate 23 is part of the connecting electrode 20, and the number of connecting holes 23a on the connecting plate 23 is unlimited. For example, the connecting plate 23 may have one connecting hole 23a. Or, the connecting plate 23 may have multiple connecting holes 23a.

[0054] In one embodiment, please refer to Figure 2 The installation space also includes a mounting groove 231a communicating with the connection hole 23a. At least a portion of the connecting plate 23 located at the connection hole 23a extends away from the elastic member 10 to form a protrusion 231. A portion of the protrusion 231 is recessed to form the mounting groove 231a. The electrical connection 12 passes through the connection hole 23a to be welded in the mounting groove 231a. This expands the welding range between the electrical connection 12 and the connecting electrode 20, further enhancing the mechanical strength of the weld and the stability of the electrical connection.

[0055] Specifically, the connecting plate 23 is located at the connecting hole 23a. It can extend a portion of the circumferential area of ​​the connecting hole 23a toward the side away from the elastic member 10 to form a protrusion 231. Alternatively, the entire circumferential area of ​​the connecting hole 23a can extend toward the side away from the elastic member 10 to form a protrusion 231.

[0056] A portion of the protrusion 231 is recessed to form a mounting groove 231a, which communicates with the connection hole 23a so that the electrical connection part 12 passes through the connection hole 23a and is then welded to the mounting groove 231a.

[0057] The extension length of the mounting groove 231a can be greater than the length of the electrical connection part 12, at which time the electrical connection part 12 is located inside the mounting groove 231a.

[0058] The extension length of the mounting groove 231a can also be less than the length of the electrical connection part 12, in which case a part of the electrical connection part 12 protrudes from the mounting groove 231a.

[0059] In one specific embodiment, the extension length of the mounting groove 231a can be greater than the length of the electrical connection portion 12, and the inner wall of the mounting groove 231a abuts against one end of the electrical connection portion 12. This further enhances the stability of the connection between the elastic member 10 and the connecting electrode 20.

[0060] In one embodiment, please refer to Figure 1 and Figure 3 The outer surface of at least a portion of the electrical connection portion 12 within the mounting space has an electroplated layer. This enhances the conductivity of the elastic element 10. Furthermore, the electroplated layer ensures a stable metallic contact between the elastic element 10 and the connecting electrode 20, thereby reducing the contact resistance between the elastic element 10 and the connecting electrode 20.

[0061] Specifically, the material of the electroplated layer is not limited. For example, the material of the electroplated layer can be gold, silver, nickel, or copper.

[0062] The thickness of the electroplated layer can be set as needed.

[0063] The number of electroplating layers is unlimited. For example, the electroplating layer may be a single layer. Alternatively, the electroplating layer may be two or more layers, thereby further improving the conductivity of the elastic element 10.

[0064] In one specific embodiment, the outer surface of at least a portion of the electrical connection portion 12 within the mounting space has an electroplated layer, the material of which includes nickel. This enhances both the conductivity of the elastic element 10 and its corrosion resistance.

[0065] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3The elastic member 10 includes two electrical connection portions 12 disposed at opposite ends of the bent portion 11. The connecting electrode 20 includes a first connecting electrode 21 and a second connecting electrode 22, which are respectively located at opposite ends of the elastic member 10 for welding to the electrical connection portions 12. Both ends of the elastic member 10 are welded to the electrical connection portions 12, thereby further ensuring the stability of the electrical connection between the elastic member 10 and the electrical connection portions 12.

[0066] Specifically, the elastic member 10 has two electrical connection portions 12 at both ends of its bent portion 11. The connecting electrode 20 includes a first connecting electrode 21 and a second connecting electrode 22. The first connecting electrode 21 and the second connecting electrode 22 are respectively arranged at both ends of the elastic member 10 and are respectively welded to the electrical connection portions 12 at opposite ends of the bent portion 11.

[0067] In one embodiment, one of the first connecting electrode and the second connecting electrode 22 has a guide rod 211, and the other has a guide hole 22a. The guide rod 211 is movably inserted into the guide hole 22a. Through the cooperation of the guide rod 211 and the guide hole 22a, the first connecting electrode 21 and the second connecting electrode 22 can move relative to each other. This guides the first connecting electrode 21 and the second connecting electrode 22 to move relative to each other along the axial direction of the guide rod 211, avoiding damage to the elastic connection structure caused by radial displacement of the first connecting electrode 21 and the second connecting electrode 22 along the guide rod 211.

[0068] Specifically, guide rod 211 refers to the component used for guiding and positioning during the movement of the first connecting electrode 21 and the second connecting electrode 22.

[0069] The guide rod 211 can restrict the movement direction of the first connecting electrode 21 and the second connecting electrode 22.

[0070] The guide hole 22a is a hole-like structure that allows the guide rod 211 to move in a certain direction inside it.

[0071] The guide rod 211 can be designed into different shapes according to design requirements, such as round, square or other specific shapes, to adapt to different guide hole 22a designs.

[0072] The size of the guide hole 22a can be adjusted according to the size of the guide rod 211 to ensure a suitable fit clearance and smooth relative movement between the guide rod 211 and the guide hole 22a.

[0073] In one embodiment, the elastic element 10 is a spring with a central through hole, and the guide rod 211 passes through the central through hole. Thus, the guide rod 211 ensures that the elastic element 10 moves within a predetermined path, reducing the offset of the elastic element 10 during extension and contraction, thereby improving the stability of the overall structure.

[0074] In one embodiment, the electronic atomizing device includes a liquid storage chamber 30a, a sealing element 40, an atomizing core, an atomizing chamber, and a power supply assembly. The liquid storage chamber 30a and the atomizing chamber are connected. The atomizing core is disposed in the atomizing chamber. The sealing element 40 is movably disposed at the connection between the liquid storage chamber 30a and the atomizing chamber.

[0075] The elastic connection structure is located on the side of the sealing element 40 away from the liquid storage chamber 30a. The connecting electrode 20 is electrically connected to the power supply assembly. The end of the elastic connection structure near the sealing element 40 is connected to the sealing element 40. When the electronic atomizing device is in operation, the elastic element 10 expands and contracts under the action of current, thereby driving the sealing element 40 to move and switching between connection and blockage between the liquid storage chamber 30a and the atomizing chamber. Thus, by controlling the expansion and contraction of the elastic connection structure with current, the position of the sealing element 40 can be controlled, thereby switching between connection and blockage between the liquid storage chamber 30a and the atomizing chamber, and thus controlling the atomization process of the electronic atomizing device.

[0076] Specifically, the elastic element 10 in the elastic connection structure is a memory metal spring.

[0077] The first connecting electrode 21 and the second connecting electrode 22 are respectively disposed at opposite ends of the shape memory metal spring and welded to the shape memory metal spring. The first connecting electrode 21 and the second connecting electrode 22 are electrically connected to the power supply component to allow current to flow through the shape memory metal spring. When the shape memory metal spring is energized, it generates heat rapidly due to the large current flowing through it. When the heat reaches the phase transformation point of the shape memory metal spring, the internal metallographic structure of the shape memory metal spring transforms from martensite to austenite, thereby causing the shape memory metal spring to elongate. The elongation of the shape memory metal spring pushes the first connecting electrode 21, which in turn drives the sealing member 40 to move, thereby connecting the liquid storage chamber 30a and the atomizing chamber. The atomized liquid enters the atomizing chamber through the liquid storage chamber 30a, thereby realizing the atomization of the atomized liquid. When the electronic atomizing liquid is de-energized, the shape memory metal spring retracts, driving the sealing member 40 to move and seal the liquid storage chamber 30a and the atomizing chamber.

[0078] The liquid storage chamber 30a is a structure of the electronic atomizing device used to store atomized liquids such as medicine and e-liquid.

[0079] The seal 40 is movably disposed at the connection between the liquid storage chamber 30a and the atomizing chamber, and is used to control the flow of atomized liquid between the two chambers.

[0080] The location of the seal 40 is not limited, as long as it enables the connection and sealing between the liquid storage chamber 30a and the atomizing chamber. For example, the seal 40 can be located inside the liquid storage chamber 30a. Or, the seal 40 can be located inside the atomizing chamber.

[0081] The atomizing core refers to the structure located inside the atomizing chamber, which is used to heat the atomizing liquid and convert it into an aerosol.

[0082] The electronic atomizing device in this application embodiment can be any type of atomizing device. For example, the electronic atomizing device is a nebulized drug delivery device, and the atomizing liquid stored in the reservoir 30a is a drug solution. Another example is an electronic cigarette, where the atomizing liquid stored in the reservoir 30a is e-liquid.
