[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410931498.7, filed on July 11, 2024, entitled “Atomizing Component and Electronic Atomizer”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, and in particular to an atomization component and an electronic atomizer. Background Technology

[0004] The heating element is an important component of the atomizer. During assembly and transportation, the lead wire of the heating element may shake or be pulled, which may cause the heating element to shift or deform, thus affecting the atomization effect.

[0005] Based on this, the prior art proposes to set several positioning grooves on the fixed base and fix the lead wire of the heating element by snapping the positioning grooves. In the process of realizing this application, the inventors found that the prior art has at least the following problems: due to the shape limitation of the positioning groove of the fixed base, when the lead wire passes through the positioning groove, there may be a problem that the lead wire cannot smoothly enter the opening of the positioning groove. In addition, this process cannot be completed by automated equipment.

[0006] Application content

[0007] In view of this, this application provides an atomizing component and an electronic atomizer, which are advantageous for threading the leads of the heating element.

[0008] This application provides an atomizing component, including:

[0009] A cannula with an internal cavity, the cannula having a proximal end and a distal end opposite each other along its length;

[0010] A heating element is housed in a cavity. The heating element includes a heating part and a lead wire connected to the heating part for conducting current.

[0011] A fixing seat is fixed to the distal end of the sleeve and at least partially housed inside the cavity. The side surface of the fixing seat includes at least two abutting planes arranged circumferentially. A lead wire channel is defined between the abutting planes and the inner surface of the sleeve. A portion of the lead wire is clamped between the abutting planes and the inner surface of the sleeve and extends out of the distal end of the sleeve through the lead wire channel.

[0012] This application also provides an electronic atomizer, including a liquid storage chamber for storing a liquid matrix and the aforementioned atomizing component, wherein the atomizing component is used to atomize the liquid matrix originating from the liquid storage chamber to generate an aerosol.

[0013] The above embodiments have at least the following beneficial effects: By providing at least two circumferential abutment planes on the side surface of the fixing base, a lead wire channel is formed between the abutment planes and the inner wall surface of the sleeve. A portion of the lead wire is held between the abutment planes and the inner wall surface of the sleeve, and passes through the lead wire channel to the distal end of the sleeve. This avoids the problem that the lead wire may not be able to smoothly enter the opening of the positioning groove when passing through the positioning groove due to the shape limitation of the positioning groove opened in the fixing base. This is advantageous for the lead wire to smoothly pass through the sleeve. In addition, using the abutment planes to guide the lead wire through the lead wire channel to the distal end of the sleeve automates the process. Attached Figure Description

[0026] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1 to 5. This application embodiment provides an atomizing assembly 100, including a sleeve 10, a heating element 20, and a mounting base 30. The sleeve 10 has a cavity 130, and a proximal end 110 and a distal end 120 opposite each other along its length. The heating element 20 is housed in the cavity 130, and includes a heating part 201 and a lead wire 202 connected to the heating part 201 for guiding current. The mounting base 30 is fixed to the distal end 120 of the sleeve 10 and is at least partially housed within the cavity 130. The side surface of the mounting base 30 includes at least two circumferentially arranged abutment planes 301. A lead wire channel 12 is defined between the abutment planes 301 and the inner wall surface of the sleeve 10. A portion of the lead wire 202 is held between the abutment planes 301 and the inner wall surface of the sleeve 10, and extends out of the distal end 120 of the sleeve 10 through the lead wire channel 12.

[0028] The atomizing assembly 100 has at least two circumferentially arranged abutment planes 301 on the side surface of the fixing base 30. These abutment planes 301 and the inner wall surface of the sleeve 10 define a lead wire channel 12. A portion of the lead wire 202 is held between the abutment planes 301 and the inner wall surface of the sleeve 10, and the lead wire 202 exits through the lead wire channel 12 to the outside of the distal end 120 of the sleeve 10. This effectively fixes the lead wire 202 and facilitates its smooth exit from the sleeve 10. Furthermore, this design avoids the problem of the lead wire 202 failing to smoothly enter the opening of the positioning groove, thus improving the assembly efficiency of the atomizing assembly 100. Additionally, the abutment planes 301 guide the lead wire 202 through the lead wire channel 12 to the outside of the distal end 120 of the sleeve 10, enabling automation of the process.

[0029] As shown in Figures 1 and 2, the sleeve 10 is a cylindrical tubular structure, and correspondingly, the cavity 130 is a cylindrical inner cavity that extends through the proximal end 110 and the distal end 120 of the sleeve 10. The sleeve 10 is made of a metallic material, such as stainless steel, and has characteristics such as high temperature resistance, high strength, and thin wall.

[0030] In some embodiments, a clamping portion is provided on the inner wall of the sleeve 10, and a portion of the lead wire 202 is clamped between the abutment plane 301 and the clamping portion. Specifically, the end face of the clamping portion opposite to the abutment plane 301 is a plane, and a portion of the lead wire 2022 is clamped between the abutment plane 301 and the plane, so that the clamping force distributed on the lead wire 202 is more uniform and stable.

[0031] As shown in Figure 2, an opening 101 is provided on the side wall of the sleeve 10. The opening 101 extends longitudinally from the proximal end 110 of the sleeve 10 and terminates at the side wall of the sleeve 10 (i.e., the other end of the opening 101 does not reach the distal end 120 of the sleeve 10, that is, the opening 101 does not penetrate the side wall of the sleeve 10). It is used to at least partially contain the liquid 40 and provide longitudinal stop for the liquid 40. The side wall of the sleeve 10 is also provided with a plurality of liquid inlets 102. The plurality of liquid inlets 102 surround the opening 101 of the sleeve 10 and are evenly distributed circumferentially along the side wall of the sleeve 10. This can increase the contact surface between the liquid 40 and the external liquid storage cavity, achieve uniform liquid conduction, and improve the liquid conduction speed.

[0032] For example, the side wall of the sleeve 10 has three inlets 102, two of which are located on both sides of the opening 101 of the sleeve 10 and are directly opposite each other. The third inlet 102 is located in the middle of the two inlets and is directly opposite the opening 101. By shortening the liquid guiding path in the storage cavity, the liquid guiding speed can be further improved. As shown in Figure 2, the heating element 201 is a heating element with a mesh structure, such as a heating mesh, which is made of at least one alloy with high resistivity, such as stainless steel, nickel-chromium, iron-chromium-aluminum, or nickel-iron. In some embodiments, the heating element 201 may also be a heating wire or a heating plate, which is coiled around the support 50.

[0033] Please refer to Figures 3 and 8. The atomizing assembly 100 also includes a liquid guide 40 housed within the sleeve 10 and surrounding the heating element 201. The lead wire 202 includes a first section 21 covered by the liquid guide 40 and a second section 22 that avoids the liquid guide 40. At least a portion of the second section 22 extends out of the distal end 120 of the sleeve 10 from the lead wire channel 12.

[0034] As can be seen, at least a portion of the second section 22 is held between the abutting plane 301 and the inner wall surface of the sleeve 10, and at least a portion of the second section 22 extends out of the distal end 120 of the sleeve 10 from the lead wire channel 12.

[0035] In one embodiment, the liquid guide 40 includes a liquid guide cotton, which includes a surrounding portion and a protrusion. The surrounding portion is housed within the cavity 130 and surrounds the heating element 201. The protrusion is at least partially housed in an opening 101 in the sidewall of the sleeve 10, and the remaining portion of the protrusion extends from the opening 101 in the sidewall of the sleeve 10 into a liquid storage cavity for storing the liquid matrix. The bottom of the protrusion abuts against the opening 101 in the sidewall of the sleeve 10, providing longitudinal stop for the protrusion through the opening 101 in the sidewall of the sleeve 10. The liquid inlet path of the liquid guide 40 is from the liquid storage cavity, the protrusion, the surrounding portion to the heating element 20, thereby transferring the liquid matrix in the liquid storage cavity to the heating element 20 for atomization to generate an aerosol.

[0036] It is understandable that the liquid guide 40 can also be made of other capillary elements with liquid guiding capabilities.

[0037] The heating element 20 includes at least two leads 202, with the second sections 22 of the two leads 202 correspondingly positioned on two adjacent abutment surfaces 301. Specifically, at least two leads 202 are fixed to one end of the heating element 201, and the heating element 201 is electrically connected to an external battery assembly via the at least two leads 202 to achieve the heating function. The at least two leads 202 are provided with an insulating sheath, which can prevent short circuits between the two leads 201 and protect the leads 201. The portions of the at least two leads 202 fixed to the heating element 201 and the portions of the at least two leads 202 electrically connected to the battery assembly are exposed, facilitating soldering or electrical connection; the portions of the at least two leads 202 opposite to the lead channel 12 are wrapped with an insulating sheath, and the slight elasticity of the insulating sheath can better clamp at least a portion of the second sections 22 of the at least two leads 202 between the abutment surface 301 and the inner wall surface of the sleeve 10.

[0038] In one embodiment, the heating element 20 includes a heating element 201 and two leads 202. The two leads 202 are respectively fixed to one end of the heating element 201, as shown in FIG2. The two leads 202 are fixed at a certain distance from the end of the heating element 201 near the proximal end 110 of the sleeve 10, and extend from the heating element 201 toward the distal end 120 of the sleeve 10.

[0039] In one embodiment, the heating element 20 includes two heating elements 201 and three leads 202. Two leads 202 are respectively fixed to one end of each of the two heating elements 201, and the other ends of the two heating elements 201 share a third lead 202. The two heating elements 201 are arranged along the axial direction of the support member 50. By supplying different magnitudes of current to the two heating elements 201 or supplying current to the two heating elements 201 in a time-sharing manner, the heating element 20 can achieve segmented heating.

[0040] The spacing between the second sections 22 of the two leads 202 is greater than the spacing between the first sections 21 of the two leads 202. It should be noted that the second sections 22 of the two leads 202 are fixed within the corresponding lead channels 12 and are spaced sufficiently wide. On the one hand, this can prevent the two leads 202 from short-circuiting. On the other hand, the second sections 22 can provide a pulling force biased to both sides to the first sections 21, so that the heating mesh is in close contact with the inner surface of the liquid guide 40, which is beneficial to improving the taste of the aerosol generated by atomization.

[0041] Taking the heating element 20 as an example, which includes two leads 202, the second section 22 of the two leads 202 is correspondingly positioned on two adjacent abutment planes 301. The distance between the second section 22 of the two leads 202 is adapted to the lead channel 12 corresponding to the two adjacent abutment planes 301 where they are positioned. During assembly, the two leads 202 can just pass through the lead channel 12 corresponding to the two adjacent abutment planes 301.

[0042] When the distance between the second segments 22 of the two leads 202 is large, the second segments 22 of the two leads 202 can be correspondingly positioned on two non-adjacent abutment planes 301. The distance between the second segments 22 of the two leads 202 is adapted to the lead channels 12 corresponding to the two non-adjacent abutment planes 301 where they are positioned. During assembly, the two leads 202 can just pass through the lead channels 12 corresponding to the two non-adjacent abutment planes 301.

[0043] Please refer to Figure 6. At least two abutment planes 301 are parallel to each other with the central axis AA′ of the fixed seat 30.

[0044] When the fixing seat 30 is assembled into the sleeve 10, the central axis of the fixing seat 30 coincides with the central axis of the sleeve 10. The lead wire 202 is parallel to the central axis of the fixing seat 30 and the central axis of the sleeve 10. By setting the abutment plane 301 to be parallel to the central axis AA′ of the fixing seat 30, the lead wire 202 can be guided to pass through the lead wire channel 12 more smoothly.

[0045] Preferably, there are four abutment surfaces 301, which are evenly distributed along the circumference of the fixing seat 30.

[0046] Specifically, the fixing base 30 includes four side surfaces, each of which is provided with an abutment plane 301, so the fixing base 30 includes four abutment planes 301. At this time, four lead wire channels 12 are defined between the fixing base 30 and the inner wall surface of the sleeve 10. During assembly, the lead wire channel 12 can be selected according to the spacing between the second sections 22 of the two leads 202, which is more flexible and more conducive to automation.

[0047] Referring again to Figure 5, the side surface of the fixing base 30 also includes a guide surface 302 connected to the abutment plane 301, the guide surface 302 being inclined toward the central axis of the fixing base 30. The side surface of the fixing base 30 also includes a concave surface 303 adjacent to the distal end 120 of the sleeve 10, the abutment plane 301 being located between the guide surface 301 and the concave surface 303, the concave surface 303 being recessed toward the central axis of the fixing base 30, and forming at least a step 31 with the abutment plane 301.

[0048] With the aforementioned side surface design, the section of the lead wire 202 that is clamped between the abutment plane 301 located in the middle and the inner wall surface of the sleeve 10 can be effectively utilized, thus better securing the lead wire 202. At the same time, the guide surface 302 guides the lead wire 202 to smoothly reach the abutment plane 301, and the concave surface 303 facilitates the atomizing assembly 100 to introduce air into the heating element 20 during use.

[0049] Optionally, a positioning protrusion 32 is provided on the guide surface 302 to position the lead wire 202 during assembly. The positioning protrusion 32 corresponds to the middle position of the abutment plane 301. The lead wire 202 passes through the positioning protrusion 32 from the lead wire channel 12 corresponding to the middle position of the abutment plane 301. Since the lead wire channel 12 corresponding to the middle position of the abutment plane 301 has the largest width, the lead wire 202 can pass through more smoothly.

[0050] Please refer to Figures 5 to 7. The side surface of the fixing base 30 also includes a side abutment surface 33 connected between two adjacent abutment planes 301. The side abutment surface 33 is interference-fitted with the inner surface of the sleeve 10, thereby forming two mutually spaced lead channels 12.

[0051] Please refer to Figures 5 and 8. Define the end of the fixing seat 30 near the far end 120 of the sleeve 10 as the bottom of the fixing seat 30, and the end opposite to the bottom of the fixing seat 30 as the top of the fixing seat 30. Each side abutment surface 33 forms a boss 34 with the bottom of the fixing seat 30.

[0052] When the fixing seat 30 is assembled to the sleeve 10, the side abutment surface 33 is interference-fitted with the inner wall surface of the sleeve 10 to fix the fixing seat 30 to the distal end of the sleeve 10, thus forming two spaced-apart lead channels 12. The fixing seat 30 can be made of a flexible material such as plastic or rubber. The elastic tension between the side abutment surface 33 and the inner wall of the sleeve 10 achieves a tight fit, thereby fixing the fixing seat 30 in the sleeve 10. Simultaneously, the distal end 120 of the sleeve 10 abuts against the boss 34, and the outer wall of the sleeve 10 is flush with the outer surface of the boss 34 (as shown in Figures 4, 8, and 10), which limits and fixes the sleeve 10 and effectively ensures that the sleeve 10 and the fixing seat 30 are coaxial.

[0053] Please refer again to Figures 1 to 4. The atomizing assembly 100 also includes a support member 50 for mounting the liquid guide 40. The support member 50 is at least partially housed in the cavity 130. The mounting base 30 also includes a through mounting base hole (not shown in the figure). The support member 50 is adapted to the mounting base hole.

[0054] For example, the support member 50 is a cylindrical rod. During assembly, the heating element 20 is first at least partially surrounded and fixed on the support member 50, and the liquid guide 40 is at least partially arranged around the heating element 20. Then, the support member 50 with the heating element 20 and the liquid guide 40 assembled is inserted into the cavity 130 of the sleeve 10. Finally, the through hole of the fixing seat is aligned with the support member 50, and at least two leads 202 of the heating element 20 are aligned with at least two lead channels 12, thereby fixing the fixing seat 30 to the distal end 120 of the sleeve 10 and at least partially housed inside the cavity 130.

[0055] Please refer to Figures 9 and 10. This application embodiment provides another type of fixing seat 30. The fixing seat 30 includes a guide portion 310, which is provided protruding from the abutment plane 301 and extends along the length direction of the fixing seat 30.

[0056] The guide portion 310 includes a sub-guide portion 311 and a sub-guide portion 312 disposed opposite to each other, for guiding the lead wire 202 through the space 121 defined between the sub-guide portion 311 and the sub-guide portion 312 on the abutment plane 301.

[0057] The guide portion 310 described above can be used to guide the movement of the lead wire 202 on the abutment plane 301 during the process of the fixing seat 30 being fixed to the cavity 130 corresponding to the distal end 120 of the sleeve 10. By providing the guide portion 310 including the sub-guide portions 311 and 312 arranged opposite to each other, in addition to guiding the lead wire 202 through the space 121 on the abutment plane 301, the guide portion 311 and the sub-guide portion 312 can further fix the lead wire 202 by limiting the movement of the lead wire 202.

[0058] Along the direction from the proximal end 110 of the sleeve 10 toward the distal end 120 of the sleeve 10, the width of the space 121 defined between the sub-guide portion 311 and the sub-guide portion 312 gradually decreases.

[0059] As the lead wire 202 passes through the top of the fixed base 30, the abutting plane 301, and the bottom of the fixed base 30 in sequence during the assembly process of the fixed base 30, the guiding effect of the abutting plane 301 can be further increased by setting the width of the space 121 defined between the guide part 311 and the sub-guide part 312 to gradually decrease.

[0060] The sub-guide section includes multiple discretely arranged protrusions or columnar protrusions; or the sub-guide section includes continuously extending ribs.

[0061] For example, the protrusions are hemispherical and the columnar protrusions are cylindrical. As shown in Figures 9 and 10, sub-guide portions 311 and 312 each include three protrusions or columnar protrusions. The protrusions or columnar protrusions of sub-guide portions 311 and 312 correspond one-to-one. The distance between the first protrusion or columnar protrusion of sub-guide portions 311 and 312 is D1, the distance between the second protrusion or columnar protrusion of sub-guide portions 311 and 312 is D2, and the distance between the third protrusion or columnar protrusion of sub-guide portions 311 and 312 is D3, satisfying D1 > D2 > D3. That is, along the direction from the proximal end 110 of the sleeve 10 to the distal end 120 of the sleeve 10 (along the direction from the top of the fixing seat 30 to the bottom of the fixing seat 30), the width of the space 121 between sub-guide portions 311 and 312 gradually decreases.

[0062] For example, sub-guide portion 311 and sub-guide portion 312 are two protruding ribs protruding from the abutment plane 301. The two ribs have a certain included angle, such that the width of the space 121 defined between the two ribs gradually decreases along the direction from the proximal end 110 of the sleeve 10 to the distal end 120 of the sleeve 10.

[0063] Please refer to Figure 11. This application provides an electronic atomizer, including a liquid storage chamber 610 for storing a liquid matrix and an atomizing component 100 as described in any of the above embodiments. The atomizing component 100 is used to atomize the liquid matrix originating from the liquid storage chamber 610 to generate an aerosol.

[0064] The electronic atomizer includes a housing 1 and a battery assembly 2. The housing 1 has a storage space for accommodating the atomizing cartridge. The battery assembly 2 is electrically connected to the atomizing cartridge and provides power to it. The atomizing cartridge includes a housing 61, a top cover 62, and a bottom cover 63. The top cover 62 and bottom cover 63 are respectively positioned at both ends of the housing 61 along its longitudinal direction. The housing 61, top cover 62, and bottom cover 63 define a liquid storage chamber 610 for storing a liquid matrix. A liquid storage cotton is also provided in the liquid storage chamber 610. The liquid storage cotton carries the liquid matrix. The liquid matrix directly reaches the liquid guide 40 or through the liquid inlet 102, and is then heated and atomized by the heating element 20 to produce an aerosol.

[0065] It is understandable that other components of an electronic atomizer can utilize any existing technology, which will not be elaborated upon here.

[0066] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
