Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generation, in particular to an electric connection structure and an aerosol generating device. BACKGROUND

[0002] The aerosol generating device generally comprises an atomizer and a power supply, and an electric connection structure is needed to electrically connect the atomizer and the power supply (such as a battery rod) during use. The electric connection structure commonly used in the market is a magnetic connection structure.

[0003] The magnet and the plastic support inside the power supply are fixed by interference riveting and combined with glue. With long-term use by the user, the plastic support inside the power supply will inevitably age, and at the same time, the condensed aerosol will corrode the plastic support. Under the influence of these two factors, when the user plugs in or unplugs the atomizer, the magnet has the risk of falling off the plastic support, which seriously affects the normal use and connection stability of the aerosol generating device.

[0004] In terms of electrical conduction between the atomizer and the power supply, the existing electric connection structure generally uses two spring electrodes to complete the circuit transmission. However, the current transmission capacity of the spring electrode is relatively limited, and once the current is too large, it is easy to cause permanent deformation that cannot be recovered, ultimately leading to contact failure of the spring electrode. In addition, for some power supplies with screens, the screen needs to read and display the resistance value of the atomizer. However, at the moment when the atomizer is just inserted into the power supply, the spring in the spring electrode is in a state of motion, and at this time the impedance of the entire spring electrode is in an unstable state, which is easy to cause the screen to display an incorrect resistance value. At the same time, the manufacturing process of the spring electrode is relatively complex, which not only leads to a high manufacturing cost, but also limits the service life of the spring electrode itself, increasing the maintenance cost and replacement frequency of the aerosol generating device.

[0038] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0039] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0040] In addition, the terms "first", "second", etc. are used only for descriptive purposes and do not connote or imply relative importance or an ordering between or among the indicated features. Thus, a feature defined with "first", "second", etc. can include one or more of the features implicitly or explicitly.

[0041] The description of "one embodiment", "some embodiments" or "an embodiment" as used in this specification means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Thus, the appearances of the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in additional embodiments" and so on, in various places in the specification are not necessarily all referring to the same embodiment, unless otherwise specified. Furthermore, the particular features, structures or characteristics can be combined in any suitable manner in one or more embodiments.

[0042] In order to illustrate the technical solutions of the present application, the following will be described in conjunction with specific drawings and embodiments.

[0043] The aerosol generating device generally includes an atomizer and a power supply. In use, an electrical connection structure is needed to electrically connect the atomizer and the power supply. Currently, a magnetic connection structure is commonly used in the market.

[0044] The magnet and the plastic support inside the power supply are fixed by interference riveting and combined with glue. With long-term use by the user, the plastic support inside the power supply will inevitably age. At the same time, condensed aerosol will corrode the plastic support. Under the influence of these two factors, when the user plugs in or plugs out the atomizer, the magnet has the risk of falling off the plastic support, which seriously affects the normal use and connection stability of the aerosol generating device.

[0045] Regarding the conductivity between the atomizer and the power supply, existing electrical connection structures typically use two spring electrodes to complete circuit transmission. However, the current transmission capacity of the spring electrodes is relatively limited, generally not exceeding 8A. If the current is too high, the springs will overheat during the current flow, leading to a decrease in spring force and irreversible permanent deformation. Ultimately, this causes the spring electrodes to fail to make contact, preventing proper circuit conduction. Furthermore, for some power supplies with screens, the screen needs to read and display the atomizer's resistance value. However, at the moment the atomizer is plugged in, the springs in the spring electrodes are in motion, and the impedance of the entire spring electrode is unstable. The chip in the aerosol generator reads the atomizer's resistance value inaccurately at this moment, causing resistance fluctuations and potentially displaying incorrect resistance values ​​on the screen, inconveniencing users. Additionally, the manufacturing process of spring electrodes is relatively complex, resulting in higher manufacturing costs. Moreover, the spring electrodes themselves have a limited lifespan, increasing the maintenance costs and replacement frequency of the aerosol generator.

[0046] In view of this, this application provides an electrical connection structure and an aerosol generating device. Since the first electrode includes a first connecting portion with a recess, and the second electrode includes a connected second connecting portion and a plurality of elastic cantilever arms, and the second connecting portion is located on the side of the elastic cantilever arms away from the first connecting portion, all the elastic cantilever arms are located in the recess and abut against the inner wall of the recess, the contact area between the first electrode and the second electrode can be increased through the elastic compression contact between the elastic cantilever arms and the inner wall of the recess, making the contact reliable and effectively solving the problem of resistance jumping. The connection stability is better, and the wall thickness at the thinnest part of the first electrode and the thinnest part of the second electrode can be made relatively thick. The impedance of the first electrode and the impedance of the second electrode are both low, and the overcurrent capability is strong. At the same time, the structure of the first electrode and the structure of the second electrode are relatively simple, and the manufacturing cost is low.

[0047] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the aerosol generating device 100 in one embodiment of this application. Figure 2 yes Figure 1 The left view of the aerosol generating device 100 shown. Figure 3 yes Figure 2 The aerosol generating apparatus 100 shown is a cross-sectional view along the MM direction. Figure 4 yes Figure 3 A magnified view of a portion of point A in the middle.

[0048] In a first aspect, the embodiments of the present application provide an electrical connection structure, comprising a first electrode 30 and a second electrode 40, one of the first electrode 30 and the second electrode 40 is used to be in electrical conduction with an atomizer 10, and the other of the first electrode 30 and the second electrode 40 is used to be in electrical conduction with a power supply 20.

[0049] In the embodiments, the first electrode 30 is used to be in electrical conduction with the atomizer 10, and the two can be directly or indirectly in electrical conduction. The second electrode 40 is used to be in electrical conduction with the power supply 20, and the two can be directly or indirectly in electrical conduction.

[0050] The first electrode 30 comprises a first connecting portion 31, and the first connecting portion 31 is provided with a recessed portion 32.

[0051] The recessed portion 32 can be a hole or a groove, etc. The recessed portion 32 can be arranged at an end of the first connecting portion 31 or other positions.

[0052] The second electrode 40 comprises a second connecting portion 41 and a plurality of elastic cantilevers 42 connected with each other, the second connecting portion 41 is located at a side of the elastic cantilevers 42 away from the first connecting portion 31, all the elastic cantilevers 42 are located in the recessed portion 32, and the elastic cantilevers 42 abut against the inner side wall of the recessed portion 32.

[0053] The end of the elastic cantilever 42 away from the second connecting portion 41 is a free end. When it is needed to plug together the atomizer 10 and the power supply 20, the first electrode 30 and the second electrode 40 can be moved close to each other, so that all the elastic cantilevers 42 are inserted into the recessed portion 32, the elastic cantilevers 42 abut against the inner side wall of the recessed portion 32 under the action of the elastic force of the elastic cantilevers 42, the contact area is large, the contact is reliable, the problem of jump resistance can be effectively solved, and the connection stability of the first electrode 30 and the second electrode 40 after being connected together is better.

[0054] Compared with a spring electrode, in the embodiments of the present application, the wall thickness of the thinnest part of the first electrode 30 and the wall thickness of the thinnest part of the second electrode 40 are both made thicker, so that the impedance of the first electrode 30 and the impedance of the second electrode 40 are both lower, and the overcurrent capacity is strong (for example, it can sustain over 15A current).

[0055] When it is needed to unplug the atomizer 10 and the power supply 20, the first electrode 30 and the second electrode 40 can be moved away from each other, the elastic cantilevers 42 are deformed and move away from the inner side wall of the recessed portion 32, at this time, the friction between the elastic cantilevers 42 and the inner side wall of the recessed portion 32 can be reduced, all the elastic cantilevers 42 can be moved out of the recessed portion 32, and the separation of the first electrode 30 and the second electrode 40 can be realized.

[0056] As can be seen from the above, the electrical connection structure provided in this application embodiment has the following advantages: the first electrode 30 includes a first connecting portion 31, the first connecting portion 31 is provided with a recessed portion 32, and the second electrode 40 includes a connected second connecting portion 41 and a plurality of elastic cantilever arms 42. The second connecting portion 41 is located on the side of the elastic cantilever arms 42 away from the first connecting portion 31, and all the elastic cantilever arms 42 are located inside the recessed portion 32. The elastic cantilever arms 42 abut against the inner sidewall of the recessed portion 32. Therefore, the contact area of ​​the first electrode 30 and the second electrode 40 can be increased through the elastic compression contact between the elastic cantilever arms 42 and the inner sidewall of the recessed portion 32, making the contact reliable and effectively solving the problem of resistance jumping. The connection stability is better, and the wall thickness at the thinnest part of the first electrode 30 and the thinnest part of the second electrode 40 can be made relatively thick. The impedance of the first electrode 30 and the impedance of the second electrode 40 are both low, and the overcurrent capability is strong. At the same time, the structure of the first electrode 30 and the structure of the second electrode 40 are relatively simple, and the manufacturing cost is low.

[0057] Optionally, the first electrode 30 and the second electrode 40 can generally be made of materials with good conductivity and toughness, such as brass or stainless steel, and their surface treatment can be gold plating, etc.

Figure 6 yes Figure 3 An exploded view of the first electrode 30 and the second electrode 40 in the aerosol generating device 100 shown. Figure 7 yes Figure 6 Another perspective view of the first electrode 30 and the second electrode 40 shown.

[0059] The second electrode 40 includes a deformation space 401, and all the elastic cantilever arms 42 are spaced apart around the deformation space 401.

[0060] By adopting the above scheme, when it is necessary to move the first electrode 30 and the second electrode 40 away from each other, the elastic cantilever 42 can be deformed and moved in the direction of the deformation space 401, thereby reducing the friction between the elastic cantilever 42 and the inner wall of the recess 32, making it easier to move all the elastic cantilever 42 out of the recess 32.

[0061] Optionally, the end of the elastic cantilever 42 near the first electrode 30 is a plug-in end 421, and the edge of the plug-in end 421 away from the deformation space 401 is provided with a chamfer or rounded corner.

[0062] With this configuration, the chamfer or rounded corners can be used for guidance, making it easy to insert all the elastic cantilever 42 into the recess 32.

[0063] Please refer to Figures 1 to 7 In some embodiments, the inner side wall of the recess 32 is provided with a stop portion 33, and the second electrode 40 comprises a fitting portion 43 provided on the elastic cantilever 42, the fitting portion 43 is in fitting connection with the stop portion 33 to limit the relative position of the first electrode 30 and the second electrode 40 in the arrangement direction of the first electrode 30 and the second electrode 40.

[0064] By adopting the above scheme, the relative position of the first electrode 30 and the second electrode 40 in the arrangement direction of the first electrode 30 and the second electrode 40 can be better limited, so that after the first electrode 30 and the second electrode 40 are connected together, the first electrode 30 and the second electrode 40 do not move relatively in the arrangement direction of the first electrode 30 and the second electrode 40.

[0065] Optionally, the stop portion 33 is a stop groove, and the fitting portion 43 is a fitting protrusion. Alternatively, the stop portion 33 is a stop protrusion, and the fitting portion 43 is a fitting groove.

[0067] An edge of the fitting protrusion away from the elastic cantilever 42 at one end close to the first electrode 30 is provided with a chamfer or a round corner; and / or, an edge of the fitting protrusion away from the elastic cantilever 42 at one end away from the first electrode 30 is provided with a chamfer or a round corner.

[0068] By adopting the above scheme, the chamfer or the round corner can be used for guidance, so that when all the elastic cantilevers 42 are inserted into the recess 32, the fitting portion 43 and the stop portion 33 are in fitting connection, and at the same time, the fitting portion 43 and the stop portion 33 can be separated.
