Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular provides a connecting electrode for an atomizer, an atomizer, and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are primarily used to heat and atomize an aerosol matrix stored within them, generating an aerosol for users to inhale. The device contains a power supply component and a heating component. The power supply component connects to the leads of the heating component via electrodes to achieve electrical conductivity, thereby heating the aerosol matrix through the heating component.

[0003] Currently, some electronic atomizing devices on the market have sealing silicone for the connecting electrodes to pass through, with the heating element's lead positioned between the connecting electrode and the sealing silicone. However, the contact area between the connecting electrode and the sealing silicone is relatively large, resulting in weak compressive stress. This makes it easy for the connecting electrode to detach from the sealing silicone, affecting the contact stability between the connecting electrode and the lead. Utility Model Content

[0004] The purpose of this application is to provide a connecting electrode for an atomizer, an atomizer, and an electronic atomizing device, aiming to solve the problem of weak clamping stress and insufficient connection stability between the connecting electrode and the sealing silicone in existing electronic atomizing devices.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide a connecting electrode for an atomizer, which is inserted into a mounting hole of an electrode seal for electrical connection with a lead of a heating element. The connecting electrode includes an electrode post and a protruding structure. The protruding structure is disposed on the outer peripheral sidewall of the electrode post and protrudes outward along the radial direction of the electrode post, forming at least two protrusions and a recess located between two adjacent protrusions. The protrusions are pressed against the inner wall of the mounting hole. The electrode seal portion and the lead portion are embedded in the recess.

[0006] In some embodiments, the protrusion structure includes a plurality of annular protrusions, and the plurality of annular protrusions are spaced apart along the axial direction of the electrode post; the annular protrusions form the convex portion, and two adjacent annular protrusions form the concave portion.

[0007] In some embodiments, the protrusion structure is a threaded structure formed on the outer peripheral sidewall of the electrode post.

[0008] In some embodiments, the protrusion structure and the electrode post are an integrated structure.

[0009] In some embodiments, a scraping portion is formed on the outer periphery of the protrusion structure.

[0010] In some embodiments, the protrusion structure includes an annular protrusion, the annular protrusion including a top surface and a bottom surface located at opposite ends, and an outer surface connecting the top surface and the bottom surface; In some embodiments, the intersection edge of the outer side surface and the top surface forms the scraping portion. In some embodiments, the scraping portion is formed by the intersection edge of the outer side surface and the bottom surface.

[0011] In some embodiments, the outer surface is perpendicular to the top surface; In some embodiments, the outer surface is perpendicular to the bottom surface.

[0012] Secondly, embodiments of this application provide an atomizer, including a heating element with a lead wire; an electrode seal with a mounting hole, the lead wire being disposed within the mounting hole; a connecting electrode, the connecting electrode being used; the connecting electrode passing through the mounting hole, the lead wire being confined between the protruding structure and the wall of the mounting hole.

[0013] In some embodiments, the mounting hole is interference-fitted with the protrusion structure, and the interference amount between the mounting hole and the protrusion structure is -0.15mm to -0.3mm.

[0014] Thirdly, this application also provides an electronic atomizing device, including a power supply component and the atomizer; the power supply component is electrically connected to the connecting electrode to supply power to the heating component.

[0015] The beneficial effects of this application are as follows: A raised structure is provided on the electrode post. Through the interference fit between the raised portion and the mounting hole, the raised portion compresses the electrode seal, causing it to deform more fully. This increases the sealing interference between the connecting electrode and the electrode seal, increases local contact stress, restricts the connecting electrode from detaching from the electrode seal, and improves the contact stability between the connecting electrode and the lead wire. Furthermore, under the compression of multiple raised portions, portions of the electrode seal and the lead wire are embedded in the recesses. The embedding of the electrode seal in the recesses effectively seals the leakage path, preventing liquid from seeping out from the gap between the connecting electrode and the electrode seal. The embedding of the lead wire in the recesses gives the lead wire an S-shaped structure, which extends and complicates the leakage path of liquid along the lead wire, effectively improving the product's sealing performance.

[0027] Some electronic atomizing devices on the market have sealing silicone for connecting electrodes to pass through, and the lead wire of the heating element is placed between the connecting electrode and the sealing silicone. However, the contact area between the connecting electrode and the sealing silicone is large and the compressive stress is weak, which makes it easy for the connecting electrode to fall off the sealing silicone, affecting the contact stability between the connecting electrode and the lead wire.

[0028] Based on this, in order to solve the above problems, this application designs a connecting electrode for an atomizer. A protruding structure is set on the electrode post. The protrusions will squeeze the electrode seal, making it deform more fully, increasing the local contact stress, preventing the connecting electrode from detaching from the electrode seal, and improving the contact stability between the connecting electrode and the lead wire. Under the squeezing action of multiple protrusions, parts of the electrode seal and the lead wire will be embedded in the recesses. The part of the electrode seal embedded in the recesses can effectively block the leakage path. The part of the lead wire embedded in the recesses makes the lead wire have an S-shaped structure, which can extend and complicate the path of liquid leakage along the lead wire, effectively improving the product's sealing performance.

[0029] See Figure 6 This application provides an electronic atomizing device, including a power supply component 2000 and an atomizer 1000; the power supply component 2000 is connected to the atomizer 1000 and is used to supply power to the atomizer 1000.

[0030] See Figure 3 , Figure 4 and Figure 5 In some embodiments, the atomizer 1000 includes a connecting electrode 100, an electrode seal 200, and a heating element 300; the heating element 300 has a lead wire 310; the electrode seal 200 has a mounting hole 210, the lead wire 310 is disposed in the mounting hole 210, the connecting electrode 100 passes through the mounting hole 210, and the lead wire 310 is limited between the connecting electrode 100 and the hole wall of the mounting hole 210.

[0031] Specifically, the power supply component 2000 is configured to be electrically connected to the connecting electrode 100. The lead 310 of the heating component 300 is clamped between the inner wall of the electrode seal 200 and the connecting electrode 100. The connecting electrode 100 and the lead 310 of the heating component 300 are in close contact to achieve electrical conduction. Subsequently, the power supply component 2000, the connecting electrode 100, and the heating component 300 can form a stable electrical path, enabling the power supply component 2000 to supply power to the heating component 300. The atomizer 1000 stores an aerosol matrix, and the heating component 300 can be electrically heated to atomize the aerosol matrix to generate atomized gas that can be inhaled by the user.

[0032] Understandably, the electronic atomizing device of this application can be a replaceable electronic atomizing device with atomizer 1000, meaning that atomizer 1000 and power supply component 2000 are detachably connected; thus, it can independently charge power supply component 2000 or independently replenish aerosol generation matrix to the connection electrode 100 of atomizer. Alternatively, the electronic atomizing device of this application can also be a disposable electronic atomizing device, meaning that connection electrode 100 of atomizer and power supply component 2000 are not detachably connected; no specific limitation is made here.

[0033] See Figure 1 and Figure 2 The connecting electrode 100 of this application is used to be inserted into the mounting hole 210 of the electrode seal 200. The connecting electrode 100 includes an electrode post 1 and a protrusion structure 2. The protrusion structure 2 is disposed on the outer peripheral sidewall 101 of the electrode post 1. The protrusion structure 2 protrudes outward along the radial direction of the electrode post 1 and forms at least two protrusions 21 and a recess 22 located between two adjacent protrusions 21. The protrusions 21 are pressed and contacted with the inner wall of the mounting hole 210. A portion of the electrode seal 100 and a portion of the lead wire 310 are embedded in the recess 22.

[0034] Specifically, the connecting electrode 100 of this application passes through the mounting hole 210 of the electrode seal 200. A protruding structure 2 is provided on the electrode post 1, and the protruding structure 2 is interference-fitted with the mounting hole 210. The electrode seal 200 is flexible, and the protruding structure 2 will squeeze the electrode seal 200, making its deformation more complete, thereby increasing the local sealing interference between the connecting electrode 100 and the electrode seal 200, increasing the local contact stress, and restricting the connecting electrode 100 from detaching from the electrode seal 200.

[0035] Furthermore, under the compression of multiple protrusions 21, the electrode seal 200 located between two adjacent protrusions 21 will be embedded in the recess 22, effectively sealing the leakage path and preventing liquid from seeping out from the gap between the connecting electrode 100 and the electrode seal 200, thus improving the product's sealing performance. The lead wire 310 located between two adjacent protrusions 21 will be embedded in the recess, making the lead wire 310 have an S-shaped structure, which can extend and complicate the leakage path of liquid along the lead wire 310, effectively improving the product's sealing performance.

[0036] Understandably, the protrusion 21, in conjunction with the electrode seal 200, can apply a greater clamping force to the lead wire 310, thereby stopping the lead wire 310, restricting its movement, and improving the contact stability between the lead wire 310 and the connecting electrode 100, thus ensuring that the heating component 300 can operate stably.

[0037] For example, the protrusion structure 2 can be an annular protrusion structure, an arc-shaped protrusion structure, a threaded protrusion structure, etc., provided on the outer peripheral sidewall 101 of the electrode post 1, in order to increase the local contact stress between the connecting electrode 100 and the electrode seal 200.

[0038] See Figure 1 and Figure 2 In some embodiments, the protrusion structure 2 includes an annular protrusion 4, which protrudes outward along the radial direction of the electrode post 1.

[0039] Specifically, the mounting hole 210 on the electrode seal 200 is a cylindrical hole structure, the annular protrusion 2 is interference-fitted with the mounting hole 210, and the annular protrusion 4 is an annular structure that protrudes outward along the radial direction of the electrode post 1. The annular side of the annular protrusion 4 is in close contact with the inner wall of the mounting hole 210, which can generate higher local contact stress and improve the connection stability between the connecting electrode 100 and the electrode seal 200.

[0040] See Figure 4 and Figure 5 The connecting electrode 100 is inserted into the mounting hole 210 at any rotation angle, and the lead wire 310 will be clamped between the annular protrusion 4 and the inner wall of the mounting hole 210. The assembly is quick and convenient, and the lead wire 310 is stably limited.

[0041] In some embodiments, the interference fit between the mounting hole 210 and the annular protrusion 4 is -0.15mm to -0.3mm.

[0042] Specifically, the interference fit between the mounting hole 210 and the annular protrusion 4 is the difference between the inner diameter of the mounting hole 210 and the outer diameter of the annular protrusion 4, so that the annular protrusion 4 can be interference-fitted in the mounting hole 210 of the electrode connection 200 to improve the local contact stress.

[0043] The interference fit between the mounting hole 210 and the annular protrusion 4 can be any value among -0.15mm, 0.20mm, -0.25mm, and -0.30mm.

[0044] For example, the number of annular protrusions 4 can be one or more; when the number of annular protrusions 4 is multiple, the multiple annular protrusions 4 can be spaced apart along the axial direction of the electrode post 1; or, the multiple annular protrusions 4 can also be spaced apart along the direction inclined relative to the axial direction of the electrode post 1, so as to satisfy the requirement of interference fit with the mounting hole 210.

[0045] See Figure 1 In some embodiments, there are multiple annular protrusions 4, and each annular protrusion 4 is spaced apart along the axial direction of the electrode post 1; the annular protrusions 4 form the protrusions 21, and two adjacent annular protrusions 4 form a recess 22.

[0046] Understandably, multiple annular protrusions 4 are provided, each annular protrusion 4 forming an independent interference fit contact ring with the inner wall of the mounting hole 210. Subsequently, the connecting electrode 100 forms multiple high-stress contacts with the sealing connector 200 through the annular protrusions 4, improving the stability of the mating structure. Furthermore, the annular protrusions 4 also form multiple sealing barriers, effectively improving the sealing reliability.

[0047] The groove between two adjacent annular protrusions 4 forms a recess 22. The annular protrusions 4 press against the inner wall of the mounting hole 210 in the radial direction. The portion of the electrode seal 200 located between the two adjacent annular protrusions 4 generates a reverse elastic restoring force, thus being compressed between the two annular protrusions 4. This compressed portion is correspondingly embedded in the recess 22, thereby causing the annular protrusions 4 and the electrode seal 200 to fit tightly together, forming an effective static seal. Furthermore, the partial embedding of the electrode seal 200 in the recess 22 can prevent the connecting electrode 100 from dislodging from the mounting hole 210, improving connection stability.

[0048] The lead wire 310 is subjected to the squeezing force of the annular protrusion 4, causing it to partially bend and deform to fit into the recess 22. Consequently, the lead wire 310 located in the mounting hole 210 has an S-shaped structure, which can extend and complicate the leakage path of liquid along the lead wire 310, effectively improving the sealing performance. Understandably, the S-shaped structure of the lead wire 310 will increase the friction between the connecting electrode 100 and the lead wire 310, improving the contact stability between the connecting electrode 100 and the lead wire 310.

[0049] See Figure 1 and Figure 2 In some embodiments, a scraping portion 3 is formed on the outer periphery of the protrusion structure 2; the scraping portion 3 is configured to scrape off the oxide layer on the surface of the lead wire 310 when the protrusion structure 2 moves relative to the lead wire 310.

[0050] It should be noted that after the lead wire 310 is set in the mounting hole 210 of the electrode seal 200, the connecting electrode 100 is then inserted into the mounting hole 210. Subsequently, the connecting electrode 100 will move relative to the lead wire 310 in the mounting hole 210, and the scraping part 3 on the outer periphery of the protruding structure 2 will scrape the surface of the lead wire 310. Understandably, due to contact with the external environment, the lead wire 310 has an oxide layer forming on its surface, which increases the contact resistance between the lead wire 310 and the connecting electrode 100, resulting in severe local heating and affecting the atomization effect of the heating component 300.

[0051] During the assembly process of the connecting electrode 100 with the electrode seal 200, the scraping part 3 of the protruding structure 2 can scrape the surface of the lead 310 to remove the oxide layer on the surface of the lead 310, so that the lead 310 and the connecting electrode 100 can achieve low resistance and high stability electrical contact, ensure electrical path performance, and improve product reliability.

[0052] For example, the outer peripheral edge of the protrusion structure 2 can be any of a right-angled edge, an acute-angled edge, or an obtuse-angled edge, as long as it can scrape off the oxide layer on the surface of the lead 310.

[0053] See Figure 1 In Figures 2 and 3, in some embodiments, the annular protrusion 4 includes a top surface 401 and a bottom surface 402 located at opposite ends, and an outer surface 403 connecting the top surface 401 and the bottom surface 402.

[0054] Specifically, the electrode post 100 has a head end 110 facing the heating component 300 and a tail end 120 away from the head end 110, with the top surface 401 of a single annular protrusion 4 facing the head end 110 and the bottom surface 402 facing the tail end 120.

[0055] Specifically, the outer surface 403 of the annular protrusion 4 is in close contact with the inner wall of the mounting hole 210, forming a high contact stress and the stress is evenly distributed; the lead wire 310 is clamped between the outer surface 403 of the annular protrusion 4 and the inner wall of the mounting hole 210, and the lead wire 310 and the annular protrusion 4 form a stable electrical contact to ensure electrical path performance.

[0056] In one example, the intersection of the outer surface 403 and the top surface 401 forms a scraping part 3; the intersection of the outer surface 403 and the top surface 401 forms any one of a right-angled edge, an acute-angled edge, and an obtuse-angled edge, which can perform a scraping function.

[0057] In another example, the intersection of the outer surface 403 and the bottom surface 402 forms a scraping part 3; the intersection of the outer surface 403 and the bottom surface 402 forms any one of a right-angled edge, an acute-angled edge, and an obtuse-angled edge, which can perform a scraping function.

[0058] In some embodiments, the outer surface 403 is perpendicular to the top surface 401, and the right-angled edge where the outer surface 403 intersects the top surface 401 forms the scraping portion 3.

[0059] Specifically, the intersection of the outer surface 403 and the top surface 401 forms a right-angle edge. When the connecting electrode 100 is inserted into the mounting hole 210, the annular protrusion 4 moves relative to the lead wire 310. The right-angle edge where the outer surface 403 and the top surface 401 intersect can generate extremely high pressure between the lead wire 310 and the lead wire 310. The stress is concentrated on the surface of the lead wire 310, so that the right-angle edge can scratch the oxide layer on the surface of the lead wire 310, thereby removing the oxide layer on the surface of the lead wire 310 and ensuring a low-resistance electrical contact effect.

[0060] In some embodiments, the outer surface 403 is perpendicular to the bottom surface 402, and the right-angled edge where the outer surface 403 intersects the bottom surface 402 forms the scraping portion 3.

[0061] Specifically, the intersection of the outer surface 403 and the bottom surface 402 forms a right-angle edge. When the connecting electrode 100 is inserted into the mounting hole 210, the annular protrusion 4 moves relative to the lead wire 310. The right-angle edge where the outer surface 403 and the bottom surface 402 intersect can generate extremely high pressure between the lead wire 310 and the lead wire 310. The stress is concentrated on the surface of the lead wire 310, so that the right-angle edge can scratch the oxide layer on the surface of the lead wire 310, thereby removing the oxide layer on the surface of the lead wire 310 and ensuring a low-resistance electrical contact effect.

[0062] In some other embodiments of this application, the protrusion structure 2 is a threaded structure formed on the outer peripheral sidewall 101 of the electrode post 1.

[0063] Specifically, the protrusion structure 2 is a continuous protrusion with the same cross-section formed along a spiral line on the outer peripheral sidewall 101 of the electrode post 1; the protrusion structure 2 can form a high contact stress with the inner wall of the mounting hole 210, increasing the clamping force between the connecting electrode 100 and the electrode seal 200; the lead wire 310 is clamped between the annular protrusion 4 and the inner wall of the mounting hole 210, so that the lead wire 310 and the annular protrusion 4 form a stable electrical contact, ensuring the electrical path performance.

[0064] Understandably, the protruding structure 2 is a convex thread structure, corresponding to the formation of a convex part 21 and a concave part 22; the outer periphery of the protruding structure 2 is located at the thread crest (the apex of the outermost ring of the thread), and the thread crest forms a scraping part 3. Then, when the protruding structure 2 moves relative to the lead wire 310, the thread crest can effectively scrape off the oxide layer on the surface of the lead wire 310, ensuring the low-resistance electrical contact effect between the lead wire 310 and the connecting electrode 100.

[0065] For example, the protrusion structure 2 is a threaded structure, and the thread profile can be, but is not limited to, triangular or sawtooth, so that the thread crest can form a scraping part 3 to effectively scrape off the oxide layer on the surface of the lead wire 310.

[0066] In some embodiments, the protrusion structure 2 and the electrode post 1 are an integrated structure.

[0067] In one specific embodiment of this invention, a CNC (Computer Numerical Control) lathe or milling machine is used to cut material from a solid bar (such as copper, aluminum, etc.) using a precision cutting tool, directly turning or milling to form the connecting electrode 100 of this application, so that the electrode post 1 and the protrusion structure 2 are an integrated structure.

[0068] For example, the material of the connecting electrode 100 can be copper, copper alloy, aluminum, etc., which has good current transmission efficiency.

[0069] In some embodiments, the material hardness of the protrusion structure 2 is configured to be greater than the hardness of the oxide layer on the surface of the lead wire 310.

[0070] Understandably, in order to achieve a better scraping effect on the oxide layer on the surface of the lead wire 310, a protrusion structure 2 with appropriate hardness is set according to the material of the lead wire 310 and the oxide layer formed thereon, so that the hardness of the material of the protrusion structure 2 is greater than the hardness of the oxide layer on the surface of the lead wire 310.

[0071] In one specific embodiment of this application, the lead wire 310 is a copper wire, and the oxide layer on its surface is mainly copper oxide and cuprous oxide; their Mohs hardness is between 3 and 4, which is relatively soft; the material of the protrusion structure 2 can be set as brass, and the Mohs hardness is configured to 4 or even higher, so that the hardness of the protrusion structure 2 is greater than the hardness of the oxide layer, which can achieve a better scraping effect; and brass is low in cost and easy to process.

[0072] See Figure 6 In one specific embodiment of this application, there are two connecting electrodes 100. The two connecting electrodes 100 are electrically connected to the power supply component 2000 (through wires or circuit board solder joints) to form positive and negative electrodes. The electrode seal 200 is provided with two mounting holes 210. The heating component 300 has two leads 310, which are respectively disposed in different mounting holes 210. The two connecting electrodes 100 are respectively inserted into different mounting holes 210 to clamp the leads 310.

[0073] The application does not specifically limit the model of the connecting electrode of the atomizer 1000, that is, the shape of the connecting electrode of the atomizer can be wine bottle-shaped, rectangular, cylindrical, etc.

[0074] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
