Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to an atomizing core, an atomizer, and an electronic atomizing device. Background Technology

[0002] In the atomizer of an electronic atomizing device, there is an atomizing core for heating the atomizing liquid to generate an aerosol. The atomizing core mainly includes a heating core body, a support, and a base. The heating core body is set in the support, and the base is set at the bottom of the metal support. The heating core body and the support are encapsulated in the atomizer housing through the base.

[0003] The bracket, needing to directly contact the heating element, is typically made of heat-resistant metal, while the base is usually made of plastic. Currently, the bracket and base are connected by inserting one end into the base, which then secures the bracket from the outside. However, due to the significant difference in thermal expansion coefficients between metal and plastic, when the atomizer operates and the temperature rises, the expansion of the plastic base is significantly greater than that of the metal bracket. This can easily cause the connection between the bracket and base to loosen or even detach, resulting in insufficient connection stability. Utility Model Content

[0004] This application provides a new atomizing coil, atomizer, and electronic atomization device to improve the connection stability of the bracket and base.

[0005] According to the first aspect, one embodiment provides an atomizing core, comprising:

[0006] The bracket has an atomizing chamber for mounting the heating element;

[0007] The base includes an insertion part that is inserted into the atomizing chamber and riveted to the chamber wall of the atomizing chamber.

[0008] A snap-fit ​​connection structure is also provided between the outer peripheral surface of the insertion part and the cavity wall of the atomizing chamber to limit the displacement of the insertion part relative to the bracket along the insertion direction.

[0009] In one embodiment, the insertion part includes a riveting section, the outer peripheral surface of which is interference-fitted with the cavity wall of the atomizing cavity, and the interference amount is 0.02mm-0.06mm.

[0010] In one embodiment, the insertion part further includes a guide section connected to the riveting section, and the outer diameter of the guide section is smaller than the inner diameter of the atomizing cavity, for guiding the riveting section to be inserted into the atomizing cavity.

[0011] In one embodiment, the snap-fit ​​connection structure includes:

[0012] A snap fastener is provided on one of the outer peripheral surface of the guide section and the cavity wall of the atomizing chamber;

[0013] And a slot is provided on the other of the outer peripheral surface of the guide section and the cavity wall of the atomizing chamber, for the buckle to be engaged.

[0014] In one embodiment, the atomizing core further includes a heating core, the heating core comprising:

[0015] The first liquid guiding element is disposed inside the atomizing chamber;

[0016] The heating element is encapsulated within the first liquid guiding component;

[0017] The end face of the insertion part near the first liquid guiding element has a capillary gap with the first liquid guiding element, which is used to retain the atomized liquid through capillary force.

[0018] In one embodiment, the gap width of the capillary gap is no greater than 0.4 mm.

[0019] In one embodiment, the base includes a seat portion, and the insertion portion protrudes from one side of the seat portion. The outer diameter of the seat portion is larger than the outer diameter of the insertion portion, which is used to abut against the bracket to limit the insertion depth of the insertion portion.

[0020] In one embodiment, the atomizing core further includes:

[0021] An outer cover is fitted onto the outside of the bracket, and a first hollow structure is provided on the peripheral wall of the outer cover;

[0022] The second liquid guiding component is disposed between the outer cover and the bracket, and the bracket has a second hollow structure on its peripheral wall;

[0023] The second liquid guiding component absorbs the atomizing liquid outside the atomizing core through the first hollow structure, and supplies the atomizing liquid to the first liquid guiding component through the second hollow structure.

[0024] According to a second aspect, one embodiment provides an atomizer, comprising:

[0025] The atomizing core described in any of the above embodiments;

[0026] The device includes a housing with a liquid storage chamber, wherein the atomizing core is disposed in the housing and the liquid storage chamber is used to store the atomizing liquid supplied to the atomizing core.

[0027] According to a second aspect, one embodiment provides an electronic atomizing device, comprising:

[0028] The atomizer described in the above embodiments;

[0029] And a power supply component, electrically connected to the atomizer, for supplying power to the atomizer.

[0030] According to the atomizing core of the above embodiment, since the insertion part of the base is inserted into and riveted to the atomizing chamber of the bracket, even though the coefficient of thermal expansion of the bracket is much smaller than that of the base, the insertion part is not prone to detaching from the atomizing chamber due to large dimensional changes in a high-temperature working environment. The snap-fit ​​connection structure restricts the displacement of the insertion part along the insertion direction, thereby positioning the insertion part and ensuring that its position is maintained during long-term use, preventing displacement and detachment from the atomizing chamber due to repeated expansion and contraction. The composite connection method formed by internal riveting and snap-fit ​​connection helps improve the connection stability of the bracket and base, ensuring a tight connection between them in both working and non-working states, preventing loosening or detachment.

[0043] 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.

[0044] 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.

[0045] 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).

[0046] In the atomizer of an electronic atomizing device, the atomizing coil 10 is the core component used to heat the atomizing liquid to generate an aerosol. In related technologies, one end of the bracket 12 in the atomizing coil 10 is inserted into the base 13, so that the base 13 is connected to the bracket 12 by external riveting. The bracket 12 is usually made of a metal material with excellent heat resistance, such as brass C3604; while the base 13 of the atomizing coil 10 is mostly made of plastic materials, such as PCTG (polyethylene terephthalate-1,4-cyclohexanediol). When the atomizing core 10 is working, the temperature of the contact area between the bracket 12 and the base 13 can reach over 80℃. The coefficient of thermal expansion of brass C3604 is about 20.5μm / (m·℃), and the coefficient of thermal expansion of PCTG is about 60-80μm / (m·℃). Therefore, the dimensional change of the bracket 12 due to the temperature rise is small, while the dimensional change of the base 13 due to the temperature rise is large. This can easily cause the connection between the bracket 12 and the base 13 to loosen or even fall off, resulting in insufficient connection stability.

[0047] In this embodiment, by employing a base 13 with an insertion portion 131, the insertion portion 131 can be inserted into and riveted fixed in the atomizing chamber 121 of the bracket 12. When the base 13 undergoes significant dimensional changes due to temperature increases, it can be riveted more tightly to the bracket 12, making it less prone to loosening or falling off. Furthermore, by further providing a snap-fit ​​connection structure 14 between the outer peripheral surface of the base 13 and the cavity wall of the atomizing chamber 121, the displacement of the insertion portion 131 along the insertion direction can be restricted, ensuring that the position of the insertion portion 131 is maintained during long-term use and preventing it from detaching from the atomizing chamber 121 due to the accumulation of displacement caused by repeated expansion and contraction. The composite connection method formed by the inner riveting and the snap-fit ​​141 helps to improve the connection stability between the bracket 12 and the base 13, ensuring that the bracket 12 and the base 13 remain tightly connected in both working and non-working states, making them less prone to loosening or detachment.

[0048] An embodiment of the atomizing core 10 in this application:

[0049] In one embodiment, please refer to Figures 1 to 5 The atomizing core 10 includes a heating core 11, a bracket 12, and a base 13.

[0050] Please refer to Figures 1 to 3 The heating core 11 can be understood as a component in the atomizing core 10 used to receive and heat the atomizing liquid to generate an aerosol. In one embodiment, the heating core 11 may include a heating element 111 and a first liquid guiding member 112, wherein the heating element 111 is enclosed in the first liquid guiding member 112 and is used to heat the atomizing liquid in the first liquid guiding member 112 to generate an aerosol.

[0051] Please refer to Figures 1 to 3The bracket 12 can be understood as the mounting base of the heating core 11. Since the heating core 11 has a high temperature when it is working, the bracket 12 can be made of copper or other metal materials. Of course, it can also be made of non-metallic materials with good heat resistance.

[0052] In one embodiment, please refer to Figure 2 The bracket 12 has an atomizing chamber 121, and the heating core 11 is installed in the atomizing chamber 121. Furthermore, a second hollow structure 122 may be provided on the peripheral wall of the bracket 12 so that the atomizing liquid outside the bracket 12 can be supplied to the heating core 11 in the atomizing chamber 121 through the second hollow structure 122.

[0053] It is understood that since the aerosol generated by the heating core 11 needs to be discharged by airflow, the atomizing chamber 121 can have an air inlet 1211 and an air outlet 1212. For example, the support 12 can be configured as a tube, with the inner cavity of the support 12 serving as the atomizing chamber 121, and the openings at both ends of the inner cavity of the support 12 serving as the air inlet 1211 and the air outlet 1212, respectively, so that the airflow can flow in from the air inlet 1211, carry away the aerosol through the heating core 11, and then flow out from the air outlet 1212.

[0054] Please refer to Figures 1 to 3 The base 13 can be disposed at the bottom end of the bracket 12 to cooperate with the atomizer housing, encapsulating the bracket 12 and the heating core 11 inside the atomizer. The base 13 can be made of a plastic material such as PCTG. In one embodiment, the base 13 includes an insertion part 131, which is inserted into the atomization chamber 121 and riveted to the chamber wall of the atomization chamber 121.

[0055] For example, please refer to Figure 2 The insertion part 131 can be inserted into the atomizing chamber 121 through the air inlet 1211 to form a riveted connection with the chamber wall of the atomizing chamber 121 when the atomizing core 10 is not in operation. Thus, when the atomizing core 10 is in operation, because the dimensional change of the insertion part 131 is greater than that of the bracket 12, the riveting between the insertion part 131 and the chamber wall of the atomizing chamber 121 can be further tightened. When the atomizing core 10 switches back to the non-operating state, the insertion part 131 and the bracket 12 can return to their initial riveted state, maintaining a stable connection. This internal riveting connection method helps to enhance the connection stability between the base 13 and the bracket 12, reducing the risk of loosening or even detachment caused by the difference in thermal expansion coefficients between the base 13 and the bracket 12.

[0056] Those skilled in the art will understand that the specific method of riveting and fixing the insertion part 131 to the cavity wall of the atomizing cavity 121 is not limited. For example, the cross-sectional dimension of the insertion part 131 can be slightly larger than the cross-sectional dimension of the atomizing cavity 121 so that the insertion part 131 is forced into the atomizing cavity 121 under the action of external force to form a riveting fixation; or the cross-sectional dimension of the insertion part 131 can be smaller than or equal to the cross-sectional dimension of the atomizing cavity 121, and after the insertion part 131 is inserted into the atomizing cavity 121, the bracket 12 is deformed by the action of external force to rivet the insertion part 131 to the inside of the bracket 12; in short, any internal riveting form that can meet the design and use requirements is acceptable.

[0057] In one embodiment, please refer to Figure 2 and Figure 3 The insertion part 131 may include a riveting section 1311, the outer peripheral surface of which is interference-fitted with the cavity wall of the atomizing chamber 121. For example, the riveting section 1311 may be cylindrical, and the air inlet 1211 may be a circular hole. Furthermore, the outer diameter of the riveting section 1311 is slightly larger than the inner diameter of the air inlet 1211, so that after the riveting section 1311 is inserted into the air inlet 1211, the outer peripheral surface of the riveting section 1311 is interference-fitted with the cavity wall of the atomizing chamber 121, forming a riveted assembly relationship.

[0058] In some embodiments, the outer diameter of the riveting section 1311 can be 0.02mm-0.06mm larger than the inner diameter of the air inlet 1211, so that the interference fit between the outer peripheral surface of the riveting section 1311 and the cavity wall of the atomizing chamber 121 is 0.02mm-0.06mm, such as 0.02mm, 0.03mm, 0.04mm, 0.05mm, or 0.06mm, etc., so that the riveting section 1311 can maintain a stable riveting relationship with the bracket 12 regardless of whether the atomizing core 10 is in a working state or not. In other embodiments, the interference fit between the outer peripheral surface of the riveting section 1311 and the cavity wall of the atomizing chamber 121 can also be less than 0.02mm or greater than 0.06mm, as long as the insertion part 131 and the bracket 12 maintain a stable connection.

[0059] To facilitate the insertion of the riveted section 1311 into the atomizing chamber 121, in one embodiment, please refer to... Figure 2 and Figure 3 The insertion part 131 also includes a guide section 1312, which is connected to the riveting section 1311 and located on one side of the riveting section 1311 along the insertion direction. The outer diameter of the guide section 1312 is smaller than the inner diameter of the atomizing cavity 121, and it is used to guide the riveting section 1311 into the atomizing cavity 121. When the insertion part 131 is inserted into the atomizing cavity 121, the guide section 1312 is inserted into the atomizing cavity 121 first, which provides guidance for the subsequent insertion of the riveting section 1311, and helps to force the riveting section 1311 into the cavity, so as to achieve riveting fixation.

[0060] Since the cavity wall of the atomizing chamber 121 restricts the circumferential thermal expansion of the insertion part 131, the thermal expansion of the insertion part 131 along the insertion direction is enhanced. As the atomizing core 10 undergoes repeated thermal expansion and recovery during long-term use, the atomizing core 10 may be displaced along the insertion direction, posing a risk of detaching from the atomizing chamber 121.

[0061] In one embodiment, please refer to Figure 2 and Figure 3 A snap-fit ​​connection structure 14 is provided between the outer peripheral surface of the insertion part 131 and the cavity wall of the atomizing chamber 121 to limit the displacement of the insertion part 131 relative to the bracket 12 in the insertion direction, so that the insertion position of the atomizing core 10 can be maintained, further reducing the risk of separation between the base 13 and the bracket 12.

[0062] In one embodiment, the snap-fit ​​connection structure 14 includes a snap-fit ​​141 and a slot 142. The snap-fit ​​141 is disposed on one of the outer peripheral surface of the insertion part 131 and the cavity wall of the atomizing cavity 121; the slot 142 is disposed on the other of the outer peripheral surface of the insertion part 131 and the cavity wall of the atomizing cavity 121, so that the snap-fit ​​141 can be snapped in.

[0063] It is understood that the snap-fit ​​connection structure 14 can be disposed on the guide section 1312 and the cavity wall of the atomizing cavity 121 opposite to the guide section 1312, or it can be disposed on the riveting section 1311 and the cavity wall of the atomizing cavity 121 opposite to the riveting section 1311. However, when disposed on the riveting section 1311 and the cavity wall of the atomizing cavity 121 opposite to the riveting section 1311, the protruding snap-fit ​​141 can easily increase the difficulty of forcibly inserting the riveting section 1311. Therefore, in one embodiment, the snap-fit ​​connection structure 14 can be disposed on the guide section 1312 and the cavity wall of the atomizing cavity 121 opposite to the guide section 1312.

[0064] For example, please refer to Figure 2 and Figure 3 The slot 142 can be an annular groove provided on the outer peripheral surface of the guide section 1312, and the buckle 141 is a corresponding annular protrusion provided on the cavity wall of the atomizing chamber 121. The annular protrusion engages with the annular groove to limit the displacement of the insertion part 131 along the insertion direction. The slot 142 can be located on the side of the guide section 1312 near the riveting section 1311, so that the buckle connection structure 14 is away from the insertion end of the insertion part 131, which helps to further reduce the risk of separation between the base 13 and the bracket 12.

[0065] Furthermore, to facilitate airflow through the base 13 into the atomizing chamber 121, in one embodiment, please refer to... Figure 2The base 13 is provided with an air intake channel 133. One end of the air intake channel 133 can be connected to the external environment, and the other end can be connected to the atomizing chamber 121 through the insertion part 131, so that the atomizing chamber 121 can be connected to the external environment.

[0066] During use, the atomizing core 10 may experience a situation where atomizing liquid enters the atomizing chamber 121 and flows along the chamber wall. To reduce the risk of atomizing liquid flowing along the chamber wall of the atomizing chamber 121 into the air intake channel 133 and leaking to the outside of the base 13, in one embodiment, please refer to... Figure 2 The insertion part 131 has a capillary gap 1313 between its end face near the first liquid guide 112 and the first liquid guide 112. The capillary gap 1313 is used to generate capillary force to retain the atomized liquid that leaks into the capillary gap 1313 through the capillary force, thereby reducing the risk of the atomized liquid flowing into the air intake channel 133 along the cavity wall of the atomizing cavity 121.

[0067] In one embodiment, the gap width of the capillary gap 1313 can be set to no more than 0.4 mm; for example, 0.1 mm, 0.2 mm, 0.3 mm, or 0.4 mm, so that the capillary gap 1313 can provide sufficient capillary force. In other embodiments, the gap width of the capillary gap 1313 can also be set to be greater than 0.4 mm, such as 0.45 mm or 0.5 mm, as long as it meets the design and usage requirements of the retention atomizing liquid.

[0068] In one embodiment, in order to facilitate the formation of capillary gap 1313 during assembly, the base 13 may further include a seat portion 132, with an insertion portion 131 protruding from one side of the seat portion 132. The outer diameter of the seat portion 132 is larger than the outer diameter of the insertion portion 131, so as to hold the bracket 12 to limit the insertion depth of the insertion portion 131 when the insertion portion 131 is inserted into the atomizing chamber 121.

[0069] In some embodiments, please refer to Figure 2 and Figure 3 The intake passage 133 includes a first passage 1331 and a second passage 1332. The first passage 1331 passes through the insertion part 131 along the insertion direction of the insertion part 131 and extends into the seat part 132. The second passage 1332 is disposed on the seat part 132 and arranged around the first passage 1331. One end of the second passage 1332 is connected to the first passage 1331 and the other end is connected to the second passage 1332.

[0070] Please refer to Figure 2An electrode hole 1321 may also be provided on the end face of the seat part 132 away from the insertion part 131. The electrode hole 1321 is arranged around the first channel 1331. A power electrode 1322 for electrical connection with the power supply is inserted in the electrode hole 1321. The electrode hole 1321 is connected to the first channel 1331. The heating element 111 may be connected with a lead wire 1111. The lead wire 1111 passes through the first channel 1331 into the electrode hole 1321 and is sandwiched between the hole wall of the electrode hole 1321 and the outer surface of the power electrode 1322, thereby making contact and conducting with the power electrode 1322.

[0071] To facilitate the insertion of lead 1111 from the first channel 1331 into electrode hole 1321, please refer to... Figure 2 A tapered protrusion 1333 may be provided at one end of the first channel 1331 away from the insertion part 131. The surface of the tapered protrusion 1333 serves as a wire guide surface, used to guide the lead wire 1111 into the electrode hole 1321 during the connection process between the base 13 and the bracket 12. In order to reduce the risk of atomizing liquid leaking to the outside of the base 13 through the electrode hole 1321, a sealing ring 1323 may be provided between the hole wall of the electrode hole 1321 near its opening end and the electrode 1322 to seal the gap between the electrode 1322 and the electrode hole 1321.

[0072] In one embodiment, please refer to Figure 4 and Figure 5 The atomizing core 10 also includes an outer cover 15 and a second liquid guiding component 16. The outer cover 15 is sleeved on the outside of the support 12, and a first perforated structure 151 is provided on the peripheral wall of the outer cover 15. The second liquid guiding component 16 is disposed between the outer cover 15 and the support 12. The second liquid guiding component 16 absorbs the atomizing liquid outside the atomizing core 10 through the first perforated structure 151 and supplies the atomizing liquid to the first liquid guiding component 112 through the second perforated structure 122 on the peripheral wall of the support 12. Both the first liquid guiding component 112 and the second liquid guiding component 16 can be liquid-guiding cotton, porous ceramic body, or other liquid-guiding components.

[0073] For example, the outer cover 15 can be configured as a tube. The support 12 has a protruding edge 123 at one end for connecting to the base 13. One side of the outer cover 15 is fitted onto the support 12, and the end face of the outer cover 15 on that side abuts against the protruding edge 123. The other end of the outer cover 15 serves as an aerosol discharge end, used to communicate with the gas in the nozzle of the atomizer. A plurality of waist-shaped holes arranged around the support 12 are provided on the peripheral wall of the outer cover 15 to serve as a first hollow structure 151, so that the inner cavity of the outer cover 15 is connected to the outside of the outer cover 15, allowing the atomizing liquid to enter the interior of the outer cover 15.

[0074] The second liquid guiding element 16 is disposed between the outer cover 15 and the support 12, and covers the outside of the support 12 to absorb the atomized liquid entering the outer cover 15 from the first hollow structure 151. The second hollow structure 122 may include a plurality of waist-shaped holes arranged inside the second liquid guiding element 16 and surrounding the support 12. The heating core 11 is disposed in the atomization chamber 121 corresponding to the second hollow structure 122, so that the second liquid guiding element 16 can supply atomized liquid to the first liquid guiding element 112 through the second hollow structure 122, and then the heating element 111 heats and generates an aerosol.

[0077] For example, the housing has a liquid storage chamber, and the opposite sides of the housing can be provided with an installation port and an aerosol outlet, respectively. The bracket 12 extends into the liquid storage chamber through the installation port, and the base 13 is sealed and assembled at the installation port. The gas outlet 1212 of the bracket 12 is connected to the gas outlet of the aerosol outlet so as to discharge the aerosol generated by the heating core 11.

It is mainly used to support the realization of all or part of the functions of the electronic atomizing device, such as controlling the heating element 111 to start and stop heating the atomizing liquid, adjusting the heating power of the heating element 111, and displaying the status information of the electronic atomizing device.

[0081] The power supply unit and the atomizer can be either fixedly connected or detachably connected. When the atomizer and power supply unit are detachably connected, both the atomizer and power supply unit can be replaced depending on the usage.
