Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electrical connection structure, an atomizer, and an atomization device. Background Technology

[0002] In traditional atomizing devices, a heating element is installed inside the atomizer. The heating element is electrically connected to a power source through electrodes. During use, the heating element is energized by the power source and electrodes, which heats and atomizes the aerosol matrix, thus generating an aerosol.

[0003] In related technologies, the connection method between the heating element and the electrode is generally spot welding. That is, the surface of the heating element and the surface of the electrode are first attached together, and then connected by spot welding. However, spot welding will damage the surface structure of the electrode (such as the gold plating layer), causing the aerosol matrix to penetrate into the inner layer of the electrode (the main structure of the inner layer of the electrode is free-machining iron), resulting in electrode corrosion. This will then release various heavy metal hazards such as lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), mercury (Hg), arsenic (AS), and antimony (Sb), affecting the safety of the aerosol generated by the atomizing device. Utility Model Content

[0047] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0048] In traditional atomizing devices, a heating element is installed inside the atomizer. The heating element is electrically connected to a power source through electrodes. During use, the heating element is energized by the power source and electrodes, which heats and atomizes the aerosol matrix, thus generating an aerosol.

[0049] In related technologies, the connection method between the heating element and the electrode is generally spot welding. That is, the surface of the heating element and the surface of the electrode are first attached together, and then connected by spot welding. However, spot welding will damage the surface structure of the electrode (such as the gold plating layer), causing the aerosol matrix to penetrate into the inner layer of the electrode (the main structure of the inner layer of the electrode is free-machining iron), resulting in electrode corrosion. This will then release various heavy metal hazards such as lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), mercury (Hg), arsenic (AS), and antimony (Sb), affecting the safety of the aerosol generated by the atomizing device.

[0050] In view of this, this application provides an electrical connection structure, an atomizer, and an atomizing device. Since one of the heating element and the electrode is provided with a first connecting portion, and the other of the heating element and the electrode is provided with a second connecting portion, and the first connecting portion includes a main body portion and a protrusion portion protruding from the surface of the main body portion, when it is necessary to electrically connect the heating element and the electrode, it is only necessary to hold the end of the protrusion portion away from the main body portion against the second connecting portion so that the main body portion and the second connecting portion are electrically connected through the protrusion portion, thereby enabling the heating element and the electrode to be electrically connected without the need for a spot welding process. Therefore, the surface structure of the electrode is not damaged, and the aerosol matrix is ​​prevented from penetrating into the inner layer of the electrode. This solves the problem of electrode corrosion causing the emission of various heavy metal hazards, which affects the safety of the aerosol generated by the atomizing device.

[0051] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the atomizer 100 in one embodiment of this application. Figure 2 yes Figure 1 The top view of the atomizer 100 shown is shown. Figure 3 yes Figure 2 The cross-sectional view of the atomizer 100 shown along the MM direction. Figure 4 yes Figure 3 A magnified view of a portion of point A in the middle.

[0052] In a first aspect, embodiments of this application provide an electrical connection structure for an atomizer 100 of an atomizing device, the electrical connection structure including a heating element 10 and an electrode 20.

[0053] Electrode 20 is used to electrically connect the power supply to the heating element 10 and the atomizing device. The heating element 10 heats up when energized, and can be used to heat and atomize the aerosol matrix, so that the aerosol matrix generates aerosol.

[0054] One of the heating element 10 and the electrode 20 is provided with a first connecting portion 101, and the other of the heating element 10 and the electrode 20 is provided with a second connecting portion 201.

[0055] In this embodiment, one of the heating element 10 and the electrode 20 is provided with a first connecting portion 101, and the other of the heating element 10 and the electrode 20 is provided with a second connecting portion 201. That is, the heating element 10 is provided with a first connecting portion 101, and the electrode 20 is provided with a second connecting portion 201; or, the heating element 10 is provided with a second connecting portion 201, and the electrode 20 is provided with a first connecting portion 101.

[0056] In the illustrated embodiment, the heating element 10 is provided with a first connecting portion 101, and the electrode 20 is provided with a second connecting portion 201. In other embodiments, the heating element 10 may also be provided with a second connecting portion 201, and the electrode 20 may be provided with a first connecting portion 101.

[0057] The first connecting portion 101 includes a main body portion 11 and a protrusion portion 12 protruding from the surface of the main body portion 11. One end of the protrusion portion 12 away from the main body portion 11 abuts against the second connecting portion 201, so that the main body portion 11 and the second connecting portion 201 are electrically connected through the protrusion portion 12.

[0058] Both the main body 11 and the protrusion 12 are conductive, and are electrically connected. The main body 11 and the protrusion 12 can be separately disposed or integrally formed. The main body 11 and the second connecting part 201 are electrically connected through the protrusion 12, thereby enabling the first connecting part 101 and the second connecting part 201 to be electrically connected, which in turn enables the heating element 10 and the electrode 20 to be electrically connected.

[0059] As can be seen from the above, the electrical connection structure provided in this application embodiment has a first connection portion 101 provided in one of the heating element 10 and the electrode 20, and a second connection portion 201 provided in the other of the heating element 10 and the electrode 20. The first connection portion 101 includes a main body portion 11 and a protrusion portion 12 protruding from the surface of the main body portion 11. Therefore, when it is necessary to electrically connect the heating element 10 and the electrode 20, it is only necessary to abut the end of the protrusion portion 12 away from the main body portion 11 against the second connection portion 201 so that the main body portion 11 and the second connection portion 201 are electrically connected through the protrusion portion 12. This allows the heating element 10 and the electrode 20 to be electrically connected without the need for a spot welding process. Therefore, it will not damage the surface structure of the electrode 20, avoid the aerosol matrix from penetrating into the inner layer of the electrode 20, and effectively prevent the corrosion of the electrode 20. This solves the problem that the electrode 20 corrodes and emits various heavy metal hazards, affecting the safety of the aerosol generated by the atomizing device.

[0060] In the electrical connection structure provided in this application embodiment, since the first connection portion 101 includes a main body portion 11 and a protrusion portion 12 protruding from the surface of the main body portion 11, and the end of the protrusion portion 12 away from the main body portion 11 abuts against the second connection portion 201, a stable contact between the protrusion portion 12 and the second connection portion 201 can be achieved, thereby enabling the main body portion 11 and the second connection portion 201 to achieve stable electrical conduction, and the contact pressure between the protrusion portion 12 and the second connection portion 201 is large, and the contact resistance is small.

[0061] Please refer to this as well. Figures 5 to 7 , Figure 5 yes Figure 3 The schematic diagram of the electrical connection structure in the atomizer 100 shown is as follows. Figure 6 yes Figure 5 The diagram shown is an exploded view of the electrical connection structure. Figure 7 yes Figure 6 Another perspective view of the electrical connection structure shown.

[0062] In this embodiment, the electrical connection structure further includes a limiting member 30, which is located on the side of the main body 11 away from the second connecting portion 201, and the limiting member 30 abuts against the main body 11 so that the protrusion 12 abuts against the second connecting portion 201.

[0063] By adopting the above solution, the position of the main body 11 can be restricted by the limiting member 30, thereby ensuring that the protrusion 12 and the second connecting part 201 can be tightly abutted, thereby enabling the main body 11 and the second connecting part 201 to achieve stable electrical conduction, and preventing deformation of the main body 11.

[0064] Optionally, the limiting member 30 is elastic, so that the limiting member 30 can apply a spring force to the main body 11, and the direction of the spring force is toward the second connecting part 201 (e.g., Figure 4 and Figure 5 (The direction indicated by the middle arrow K).

[0065] This configuration ensures that the limiting member 30 always abuts against the main body 11, so that the protrusion 12 and the second connecting part 201 are stably abutted and there is an elastic buffer between them, effectively preventing the protrusion 12 and the second connecting part 201 from failing to stably abut due to slight changes in the relative position of the limiting member 30 and the main body 11.

[0066] It should be noted that the limiting member 30 can be made of rubber, silicone, or other elastic materials. The limiting member 30 can also be made of insulating material.

[0067] Optionally, the electrical connection structure also includes a support member 40, which is located on the side of the limiting member 30 away from the main body 11, and the support member 40 abuts against the limiting member 30.

[0068] This configuration allows the limiting member 30 to abut tightly against the main body 11, thereby ensuring that the protrusion 12 abuts tightly against the second connecting part 201.

[0069] Please refer to Figures 7 to 10 , Figure 7 yes Figure 6 Another perspective view of the electrical connection structure shown. Figure 8 yes Figure 5 The diagram shows the structure of the heating element 10 in the electrical connection structure. Figure 9 yes Figure 8 The left view of the heating element 10 shown. Figure 10 yes Figure 9 A magnified view of a section at point B in the middle.

[0070] The number of protrusions 12 is multiple, and the multiple protrusions 12 are arranged at intervals.

[0071] By adopting the above solution, multiple protrusions 12 can simultaneously abut against the second connecting portion 201, thereby achieving electrical conduction between the main body portion 11 and the second connecting portion 201. This enables stable electrical conduction between the main body portion 11 and the second connecting portion 201, increases the contact area between the first connecting portion 101 and the second connecting portion 201, and reduces the contact resistance between the first connecting portion 101 and the second connecting portion 201.

[0072] Optionally, a plurality of protrusions 12 are spaced apart along the length direction of the main body 11.

[0073] This arrangement allows the multiple protrusions 12 to occupy a large space only in the length direction of the main body 11, and a small space in other directions, thus facilitating the arrangement of the positions of the multiple protrusions 12.

[0074] For example, in Figure 8 In the middle, multiple protrusions 12 are distributed at intervals along the length direction of the main body 11, and the length direction of the main body 11 is the vertical direction.

[0075] Optionally, the distance U between two adjacent protrusions 12 is 1.60mm-2.00mm, such as 1.60mm, 1.70mm, 1.75mm, 1.80mm, 1.90mm or 2.00mm.

[0076] This design avoids the problem that the distance U between two adjacent protrusions 12 is too small, which may result in all protrusions 12 not being able to tightly abut against the second connecting part 201. It also avoids the problem that the distance U between two adjacent protrusions 12 is too large, which may result in the main body 11 between the two adjacent protrusions 12 not being effectively supported and bending.

[0077] The number of protrusions 12 can be 3 or 4.

[0078] For example, the distance U between two adjacent protrusions 12 is 1.80 mm, and the number of protrusions 12 is 3.

[0079] Please refer to Figures 7 to 10 In this embodiment, the protrusion 12 is shaped like a frustum, with the smaller diameter end of the frustum abutting against the second connecting part 201, and the larger diameter end of the frustum connected to the main body part 11.

[0080] By adopting the above solution, the protrusion 12 can stably abut against the second connecting part 201, and the protrusion 12 and the main body 11 can have a sufficiently large connection strength, and the structure of the protrusion 12 is more stable.

[0081] Optionally, the side of the smaller diameter end of the frustum is rounded.

[0082] This design prevents the side of the smaller diameter end of the frustum from scratching the second connecting part 201 when the smaller diameter end of the frustum is held against the second connecting part 201.

[0083] Optionally, the major diameter D1 of the frustum is 0.80mm-1.00mm, such as 0.80mm, 0.85mm, 0.90mm, 0.95mm or 1.00mm, etc.; the minor diameter D2 of the frustum is 0.50mm-0.70mm, such as 0.50mm, 0.55mm, 0.60mm, 0.65mm or 0.70mm, etc.; and the height H of the frustum is 0.15mm-0.30mm, such as 0.15mm, 0.20mm, 0.25mm, 0.28mm or 0.30mm, etc.

[0084] This design simplifies the structure of the frustum and makes it easier to manufacture.

[0085] For example, the major diameter D1 of the frustum is 0.92 mm, the minor diameter D2 is 0.66 mm, and the height H is 0.20 mm.

[0086] It is understood that in other embodiments, the major diameter D1, minor diameter D2, and height H of the frustum can also be other values, which will not be elaborated here.

[0087] Please refer to Figures 5 to 7 In this embodiment, the electrode 20 is made of a magnetic material with conductivity.

[0088] By adopting the above scheme, the electrode 20 can be made magnetic and directional, thereby attracting other magnetically conductive materials and conducting electricity at the same time.

[0089] Among them, the conductive magnetic material can be iron(II,III) oxide, magnetic semiconductor, or dilute magnetic semiconductor, etc.

[0090] For example, the electrode 20 is made of an inner layer of free-cutting iron and a gold-plated layer covering the free-cutting iron. The thickness of the gold-plated layer is 2.5μm-3.5μm, such as 2.5μm, 2.7μm, 2.9μm, 3.0μm, 3.2μm, 3.3μm or 3.5μm.

[0091] It should be noted that in other embodiments, the electrode 20 may also be made of a non-magnetic material with conductivity, such as iron, copper, copper alloy or aluminum alloy.

[0092] Optionally, the main body 11 and the protrusion 12 are integrally formed.

[0093] With this design, the main body 11 and the protrusion 12 can be manufactured in one piece, which is simple and convenient to operate. Moreover, the connection strength between the main body 11 and the protrusion 12 is high, and they are not easy to separate.

[0094] Understandably, the main body 11 and the protrusion 12 can be manufactured together by means of integral stamping. When the protrusion 12 is shaped like a frustum, the main body 11 and the protrusion 12 can be manufactured together by integral molding, which is simple to operate and has a low cost.

[0095] It is also understandable that when the main body 11 and the protrusion 12 are manufactured together by integral molding, one end of the protrusion 12 protrudes from one surface of the main body 11 and abuts against the second connecting part 201, while the other end of the protrusion 12 is recessed from the other surface of the main body 11.

[0096] Please refer to Figure 11, Figure 11 This is an exploded structural diagram of the electrical connection structure in another embodiment of this application.

[0097] In order to better limit the relative position of the protrusion 12 and the second connecting portion 201 after the end of the protrusion 12 away from the main body 11 abuts against the second connecting portion 201, and to prevent the protrusion 12 and the second connecting portion 201 from moving relative to each other at will, in some embodiments, the second connecting portion 201 is provided with a recess 13, and the protrusion 12 abuts against the inner wall surface of the recess 13.

[0098] By adopting the above solution, the recessed portion 13 can be used to limit the position of the protruding portion 12, preventing the protruding portion 12 from moving randomly relative to the recessed portion 13.

[0099] It should be noted that the recess 13 can be a hole or a groove, etc., and the protrusion 12 is inserted into the recess 13. The cross-section of the recess 13 can be adapted to the cross-section of the protrusion 12. The protrusion 12 can abut against the bottom wall surface of the recess 13.

[0100] For example, the cross-section of the recessed portion 13 and the cross-section of the protrusion 12 are both set to be circular, the recessed portion 13 is set to be a blind hole with a circular cross-section, and the protrusion 12 is shaped like a frustum.

[0101] In other embodiments, the cross-section of the recess 13 and the cross-section of the protrusion 12 can both be set as rectangles, squares, trapezoids or triangles, etc.

[0102] In related technologies, the temperature of the heating element 10 is generally designed to be relatively high. The temperature of the main atomization zone corresponding to its heating part 102 is around 289°C. Due to the excessively high temperature of the heating element 10, the aerosol matrix is ​​prone to chemical reactions at high temperatures, producing harmful substances such as formaldehyde, acetaldehyde, acetone, acrolein, and propionaldehyde, which affect the safety of the aerosol generated by the atomization device.

[0103] To solve the above problems, please refer to Figures 7 to 10 In this embodiment, the heating element 10 includes a heating part 102, which includes a heating line 1021. The width W of the heating line 1021 is 0.06mm-0.14mm, such as 0.06mm, 0.08mm, 0.09mm, 0.11mm, 0.12mm or 0.14mm, etc., and the thickness of the heating line 1021 is 0.05mm-0.12mm, such as 0.05mm, 0.07mm, 0.09mm, 0.10mm or 0.12mm, etc.

[0104] By adopting the above solution, the temperature of the heating element 10 can be reduced, resulting in a lower temperature in the main atomization zone corresponding to the heating part 102. This effectively reduces the possibility of chemical reactions occurring in the aerosol matrix during atomization and improves the safety of the atomized aerosol.

[0105] For example, the temperature of the main atomization zone corresponding to the heating element 102 in the electrical connection structure provided in this application embodiment can be around 214°C.

[0106] The heating circuit 1021 may include multiple ring circuits, which are used together to heat and atomize the aerosol matrix. The thickness of the heating circuit 1021 may be equal to the thickness of the main body 11. When the main body 11 and the protrusion 12 are integrally formed, the main body 11, the protrusion 12 and the heating circuit 1021 can be integrally formed. Since the protrusion 12 is formed by stamping, the thickness of the main body 11 is slightly greater than the thickness of the protrusion 12. The shape of the main body 11 may be approximately "L".

[0107] Optionally, the heating circuit 1021 may be made of one of the following materials: iron-chromium-aluminum, nickel-chromium, and stainless steel.

[0108] This design makes it easier to manufacture the heating circuit 1021 and reduces production costs.

[0109] It is understandable that the material of the heating circuit 1021 and the material of the first connecting part 101 can be the same.

[0110] Optionally, the heating element 10 is provided with two first connecting parts 101, which are spaced apart. The heating element 102 is located between the two first connecting parts 101, and both first connecting parts 101 are connected to the heating element 102 and are electrically connected. There are also two second connecting parts 201, which correspond one-to-one with the first connecting parts 101.

[0111] This configuration allows the two first connecting parts 101 to be electrically connected to the corresponding second connecting parts 201 through their corresponding protrusions 12, thereby improving the stability of the connection between the first connecting parts 101 and the second connecting parts 201.

[0112] It is understandable that there are two electrodes 20, which can be a positive electrode 20 and a negative electrode 20, respectively.

[0113] Optionally, the heat-generating part 102 includes a heat dissipation line 1022, which is located between the heat-generating line 1021 and the first connection part 101. One end of the heat dissipation line 1022 is connected to the heat-generating line 1021 and is electrically conductive, and the other end of the heat dissipation line 1022 extends toward the first connection part 101 and is spaced apart from the first connection part 101.

[0114] This configuration allows heat to be dissipated through the heat dissipation line 1022.

[0115] It is understood that heat dissipation lines 1022 can be provided on both sides of the heating line 1021. When the heating line 1021 includes multiple ring lines, one ring line corresponds to two heating lines 1021. The main body 11, the protrusion 12, the heating line 1021 and the heat dissipation line 1022 can be integrally formed, such as integrally stamped, and the thickness of the heat dissipation line 1022 can be equal to the thickness of the heating line 1021.

[0116] It is also understandable that the material of heat dissipation circuit 1022 and heat generation circuit 1021 can be the same.

[0117] Secondly, embodiments of this application provide an atomizer 100, which includes the electrical connection structure as described in the first aspect.

[0118] The atomizer 100 provided in this application embodiment has a first connecting portion 101 provided in one of the heating element 10 and the electrode 20, and a second connecting portion 201 provided in the other of the heating element 10 and the electrode 20. The first connecting portion 101 includes a main body portion 11 and a protrusion portion 12 protruding from the surface of the main body portion 11. Therefore, when it is necessary to electrically connect the heating element 10 and the electrode 20, it is only necessary to abut the end of the protrusion portion 12 away from the main body portion 11 against the second connecting portion 201 so that the main body portion 11 and the second connecting portion 201 are electrically connected through the protrusion portion 12. This allows the heating element 10 and the electrode 20 to be electrically connected without the need for a welding process. Therefore, it does not damage the surface structure of the electrode 20 and avoids the aerosol matrix from penetrating into the inner layer of the electrode 20. This solves the problem of corrosion of the electrode 20 causing the emission of various heavy metal hazards and affecting the safety of the aerosol generated by the atomizing device.

[0119] It should be noted that the atomizer 100 provided in this application embodiment may also include a liquid storage component 50, a liquid guiding cotton, a sealing silicone, a plastic component, a liquid absorbing cotton, and a plastic base, etc. The liquid storage component 50 is provided with a liquid storage chamber for storing the aerosol matrix. The aerosol matrix in the liquid storage chamber can flow to the liquid guiding cotton. The heating element 10 is used to heat and atomize the aerosol matrix in the liquid guiding cotton. The sealing silicone may include an upper sealing silicone disposed at one end of the plastic component and a lower sealing silicone disposed at the other end of the plastic component. The liquid guiding cotton and the heating element 10 are both disposed inside the plastic component. The electrode 20 is connected to the plastic base. The end of the support member 40 away from the limiting member 30 abuts against the inner wall of the liquid storage component 50 or against the plastic component, etc.

[0120] Thirdly, embodiments of this application provide an atomizing device, which includes the atomizer as described in the second aspect.

[0121] The atomizing device provided in this application embodiment has a first connecting portion 101 on one of the heating element 10 and the electrode 20, and a second connecting portion 201 on the other of the heating element 10 and the electrode 20. The first connecting portion 101 includes a main body portion 11 and a protrusion portion 12 protruding from the surface of the main body portion 11. Therefore, when it is necessary to electrically connect the heating element 10 and the electrode 20, it is only necessary to abut the end of the protrusion portion 12 away from the main body portion 11 against the second connecting portion 201 so that the main body portion 11 and the second connecting portion 201 are electrically connected through the protrusion portion 12. This allows the heating element 10 and the electrode 20 to be electrically connected without the need for a welding process. Therefore, it does not damage the surface structure of the electrode 20 and avoids the aerosol matrix from penetrating into the inner layer of the electrode 20. This solves the problem of corrosion of the electrode 20 causing the discharge of various heavy metal hazards, which affects the safety of the aerosol generated by the atomizing device.

[0122] It should be noted that the atomizing device provided in the embodiments of this application may also include a power supply, a circuit board, and a control switch, etc. The electrode 20 can be electrically connected to the power supply through the circuit board. This is something that those skilled in the art should be able to understand, and is well known and easy to implement for those skilled in the art. Moreover, it is not related to the purpose of this application. Therefore, the embodiments of this application will not be described in detail.

[0123] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
