[0023] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] See also Figures 1 to 5 The embodiment of the present application provides an atomization assembly 100, including a sleeve 10, a heating element 20 and a fixing seat 30. A cavity 130 is provided in the sleeve 10, and the sleeve 10 has a proximal end 110 and a distal end 120 opposite to each other along the length direction. The heating element 20 is accommodated in the cavity 130, and the heating element 20 includes a heating portion 201 and a lead 202 connected to the heating portion 201 for guiding current. The fixing seat 30 is fixed to the distal end 120 of the sleeve 10 and at least partially accommodated in the cavity 130 inside the cavity 130. The side surface of the fixing seat 30 includes at least two abutment planes 301 arranged in the circumferential direction, and the abutment planes 301 and the inner wall surface of the sleeve 10 define a lead channel 12, and a partial section of the lead 202 is clamped between the abutment plane 301 and the inner wall surface of the sleeve 10, and passes through the distal end 120 of the sleeve 10 from the lead channel 12.

[0025] The above-mentioned atomizer assembly 100 is formed by at least two abutment planes 301 arranged circumferentially on the side surface of the fixing seat 30, and a lead wire channel 12 is defined between the abutment plane 301 and the inner wall surface of the sleeve 10. A partial section of the lead wire 202 is clamped between the abutment plane 301 and the inner wall surface of the sleeve 10, and the lead wire 202 passes through the distal end 120 of the sleeve 10 from the lead wire channel 12, thereby effectively fixing the lead wire 202, and at the same time, it is beneficial for the lead wire 202 to pass through the sleeve 10 smoothly. In addition, on the one hand, since the problem that the lead wire 202 cannot smoothly enter the opening of the positioning groove is avoided, the assembly efficiency of the atomizer assembly 100 can also be improved; on the other hand, the abutment plane 301 is used to guide the lead wire 202 to pass through the distal end 120 of the sleeve 10 from the lead wire channel 12, so that the process can be automated.

[0026] like Figure 1 and Figure 2 As shown, the sleeve 10 is a cylindrical tubular structure, and correspondingly, the cavity 130 is a cylindrical inner cavity, which runs through the proximal end 110 and the distal end 120 of the sleeve 10. The sleeve 10 is made of metal material, such as stainless steel, and has the characteristics of high temperature resistance, high strength, and thin wall.

[0027] In some embodiments, a clamping portion is provided on the inner wall of the sleeve 10, and a portion of the lead 202 is clamped between the abutting plane 301 and the clamping portion. Specifically, the end surface of the clamping portion opposite to the abutting plane 301 is a plane, and a portion of the lead 202 is clamped between the abutting plane 301 and the plane, so that the clamping force distributed on the lead 202 is more uniform and stable.

[0028] like Figure 2 As shown, an opening 101 is provided on the side wall of the sleeve 10, and 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, i.e., the opening 101 does not penetrate the side wall of the sleeve 10), and is used to at least partially accommodate the guiding liquid 40 and provide longitudinal stop for the guiding liquid 40. The side wall of the sleeve 10 is also provided with a plurality of liquid inlets 102, and the plurality of liquid inlets 102 surround the opening 101 of the sleeve 10 and are evenly distributed along the circumference of the side wall of the sleeve 10, so as to increase the contact surface between the guiding liquid 40 and the external liquid storage cavity, realize uniform guiding of liquid, and improve the guiding speed of liquid.

[0029] For example, the side wall of the sleeve 10 is provided with three liquid inlets 102, two of which are distributed on both sides of the opening 101 of the sleeve 10, and the two liquid inlets 102 are arranged opposite to each other, and the other liquid inlet 102 is located in the middle of the two liquid inlets 102 and is arranged opposite to the opening 101, so that the liquid guiding speed can be further improved by shortening the liquid guiding path of the liquid in the liquid storage cavity. Figure 2 As shown, the heating part 201 is a heating element with a mesh structure, such as a heating mesh, which is made of at least one alloy with a high resistivity such as stainless steel, nickel-chromium, iron-chromium-aluminum, nickel-iron, etc. In some embodiments, the heating part 201 can also use a heating wire or a heating sheet, which is curled around the support member 50.

[0030] See also Figure 3 and Figure 8 The atomizer assembly 100 also includes a liquid guide 40 housed in the sleeve 10 and surrounding the heating portion 201. The lead wire 202 includes a first section 21 covered by the liquid guide 40 and a second section 22 avoiding the liquid guide 40. At least a portion of the second section 22 passes through the distal end 120 of the sleeve 10 from the lead wire channel 12.

[0031] It can be seen that at least a portion of the second section 22 is clamped between the abutting plane 301 and the inner wall surface of the sleeve 10 , and at least a portion of the second section 22 passes through the guide wire channel 12 to the outside of the distal end 120 of the sleeve 10 .

[0032] In one embodiment, the liquid-guiding liquid 40 includes liquid-guiding cotton, which includes a surrounding portion and a protruding portion. The surrounding portion is accommodated in the cavity 130 and is arranged around the heating portion 201; the protruding portion is at least partially accommodated in the opening 101 of the side wall of the sleeve 10, and the other part of the protruding portion extends from the opening 101 of the side wall of the sleeve 10 to the liquid storage cavity storing the liquid matrix. The bottom of the protruding portion abuts against the opening 101 of the side wall of the sleeve 10, and the protruding portion is provided with a longitudinal stop by the opening 101 of the side wall of the sleeve 10. The liquid inlet path of the liquid-guiding liquid 40 is from the liquid storage cavity, the protruding portion, the surrounding portion to the heating element 20, so that the liquid matrix in the liquid storage cavity is transferred to the heating element 20 for atomization to generate an aerosol.

[0033] It is understandable that the liquid-conducting material 40 may also be other capillary elements with liquid-conducting capabilities.

[0034] The heating element 20 includes at least two leads 202, and the second sections 22 of the two leads 202 are correspondingly positioned at two adjacent abutment planes 301. Specifically, at least two leads 202 are fixed to one end of the heating portion 201, and the heating portion 201 is electrically connected to the external battery assembly through at least two leads 202 to achieve the heating function. At least two leads 202 are provided with an insulating sheath, which can prevent the two leads 201 from short-circuiting on the one hand, and protect the leads 201 on the other hand. The fixed parts of at least two leads 202 and the heating portion 201 and the parts of at least two leads 202 electrically connected to the battery assembly are exposed, which is convenient for welding or electrical connection; the parts of at least two leads 202 corresponding to the lead channel 12 are wrapped with an insulating sheath, and the micro-elasticity of the insulating sheath can better clamp at least part of the second section 22 of at least two leads 202 between the abutment plane 301 and the inner wall surface of the sleeve 10.

[0035] In one embodiment, the heating element 20 includes a heating portion 201 and two lead wires 202. The two lead wires 202 are respectively fixed to one end of the heating portion 201. Figure 2 As shown, two lead wires 202 are fixedly connected to one end of the heating portion 201 away from the proximal end 110 of the sleeve 10 at a certain distance, and extend from the heating portion 201 to the distal end 120 of the sleeve 10 .

[0036] In one embodiment, the heating element 20 includes two heating parts 201 and three lead wires 202. The two lead wires 202 are respectively fixed to one end of the two heating parts 201, and the other ends of the two heating parts 201 share the third lead wire 202. The two heating parts 201 are arranged along the axial direction of the support member 50, and the heating element 20 is heated in sections by supplying currents of different magnitudes to the two heating parts 201 or supplying currents to the two heating parts 201 in different time periods.

[0037] The spacing between the second sections 22 of the two lead wires 202 is greater than the spacing between the first sections 21 of the two lead wires 202. It should be noted that the second sections 22 of the two lead wires 202 are fixed in the corresponding lead wire channels 12 and are spaced at a sufficiently wide spacing, which can avoid short circuits between the two lead wires 202 on the one hand, and on the other hand, the second sections 22 can provide a pulling force biased toward both sides of the first section 21, so that the heating network is closely attached to the inner surface of the liquid guide 40, which is conducive to improving the taste of the aerosol generated by atomization.

[0038] Taking the heating element 20 including two lead wires 202 as an example, the second sections 22 of the two lead wires 202 are correspondingly positioned at two adjacent abutting planes 301, and the spacing between the second sections 22 of the two lead wires 202 is adapted to the lead wire channels 12 corresponding to the two adjacent abutting planes 301 where they are positioned. During assembly, the two lead wires 202 can just pass through the lead wire channels 12 corresponding to the two adjacent abutting planes 301.

[0039] When the spacing between the second sections 22 of the two leads 202 is large, the second sections 22 of the two leads 202 can be correspondingly positioned at two non-adjacent abutment planes 301, and the spacing between the second sections 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.

[0040] See also Figure 6 At least two abutting planes 301 are parallel to the central axis AA′ of the fixing seat 30 .

[0041] 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, and the lead 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 and the central axis AA′ of the fixing seat 30 to be parallel to each other, the lead 202 can be guided to pass through the lead channel 12 more smoothly.

[0042] Preferably, the number of the abutment planes 301 is four, and the four abutment planes 301 are evenly distributed along the circumference of the fixing seat 30 .

[0043] Specifically, the fixing seat 30 includes four side surfaces, each of which is provided with an abutting plane 301, so the fixing seat 30 includes four abutting planes 301. At this time, four lead channels 12 are defined between the fixing seat 30 and the inner wall surface of the sleeve 10. During assembly, the lead channels 12 can be selected according to the spacing between the second sections 22 of the two lead wires 202, which is relatively more flexible and more conducive to automation.

[0044] Please refer again Figure 5 The side surface of the fixing seat 30 further includes a guide surface 302 connected to the abutting plane 301, and the guide surface 302 is inclined toward the central axis of the fixing seat 30. The side surface of the fixing seat 30 further includes an inner concave surface 303 adjacent to the distal end 120 of the sleeve 10, and the abutting plane 301 is located between the guide surface 301 and the inner concave surface 303. The inner concave surface 303 is recessed toward the central axis of the fixing seat 30, and at least partially forms a step 31 with the abutting plane 301.

[0045] By setting the side surface as described above, the partial section between the abutting plane 301 located in the middle and the inner wall surface of the sleeve 10 can be effectively utilized to clamp the lead 202, so as to better fix the lead 202. At the same time, the guide surface 302 guides the lead 202 to smoothly reach the abutting plane 301, and the setting of the inner concave surface 303 facilitates the atomizer assembly 100 to pass air into the heating element 20 during use.

[0046] Optionally, a positioning protrusion 32 is provided on the guide surface 302 to locate the position of the lead 202 during assembly. The positioning protrusion 32 corresponds to the middle position of the abutting plane 301, and the lead 202 passes through the lead channel 12 corresponding to the middle position of the abutting plane 301 through the positioning protrusion 32. Since the width of the lead channel 12 corresponding to the middle position of the abutting plane 301 is the largest, the lead 202 can pass through more smoothly.

[0047] See also Figures 5 to 7 The side surface of the fixing seat 30 also includes a side abutting surface 33 connected between two adjacent abutting planes 301. The side abutting surface 33 is interference fit with the inner surface of the sleeve 10, thereby forming two mutually spaced lead channels 12.

[0048] See also Figure 5 and Figure 8 , defining the end of the fixing seat 30 close to the distal 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 , and each side abutment surface 33 forms a boss 34 with the bottom of the fixing seat 30 .

[0049] When the fixing seat 30 is assembled to the sleeve 10, the side abutment surface 33 and the inner wall surface of the sleeve 10 are interference fit, so that the fixing seat 30 is fixed to the distal end of the sleeve 10, and two mutually spaced lead channels 12 are constructed. The fixing seat 30 can be made of a soft elastic material such as plastic or rubber, and the side abutment surface 33 and the inner wall of the sleeve 10 are tightly fit through the elastic tension, so that the fixing seat 30 is fixed to the sleeve 10. At the same time, 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 side surface of the boss 34 (such as Figure 4 , Figure 8 and Fig.10As shown), it is used to limit and fix the sleeve 10 and effectively ensure that the sleeve 10 is coaxial with the fixing seat 30.

[0050] Please refer again Figures 1 to 4 The atomizing assembly 100 further includes a supporting member 50 for mounting the liquid guide 40. The supporting member 50 is at least partially accommodated in the cavity 130. The fixing seat 30 further includes a fixing seat through hole (not shown) extending therethrough. The supporting member 50 is adapted to fit the fixing seat through hole.

[0051] For example, the support member 50 is a cylindrical rod. During assembly, the heating element 20 is firstly at least partially surrounded and fixed on the support member 50, the liquid-conducting liquid 40 is at least partially arranged around the heating element 20, and then the support member 50 assembled with the heating element 20 and the liquid-conducting liquid 40 is inserted into the cavity 130 of the sleeve 10, and finally the through hole of the fixing seat is aligned with the support member 50, and the at least two lead wires 202 of the heating element 20 are aligned with the at least two lead wire channels 12, so that the fixing seat 30 is fixed to the distal end 120 of the sleeve 10, and at least partially accommodated in the cavity 130.

[0052] See also Fig. 9 and Fig.10 The embodiment of the present application provides another fixing seat 30 , which includes a guide portion 310 . The guide portion 310 is protruding from the abutting plane 301 and is extended along the length direction of the fixing seat 30 .

[0053] The guide portion 310 includes a sub-guide portion 311 and a sub-guide portion 312 that are arranged opposite to each other, and is used to guide the lead wire 202 to pass through the space 121 defined between the sub-guide portion 311 and the sub-guide portion 312 on the abutting plane 301 .

[0054] The above guide portion 310 can be used to guide the movement of the lead wire 202 on the abutment plane 301 during the process of fixing the fixing seat 30 to the cavity 130 corresponding to the distal end 120 of the sleeve 10. By setting the guide portion 310 to include the sub-guide portion 311 and the sub-guide portion 312 arranged opposite to each other, in addition to guiding the lead wire 202 to pass through the space 121 on the abutment plane 301, the lead wire 202 can also be further fixed through the limiting effect of the sub-guide portion 311 and the sub-guide portion 312.

[0055] Along the direction from the proximal end 110 of the cannula 10 toward the distal end 120 of the cannula 10 , the width of the space 121 defined between the sub-guide portions 311 and 312 gradually decreases.

[0056] During the assembly of the fixing seat 30, the lead 202 passes through the top of the fixing seat 30, the abutment plane 301 and the bottom of the fixing seat 30 in sequence. By gradually reducing the width of the space 121 defined between the guide portion 311 and the sub-guide portion 312, the guiding effect of the abutment plane 301 can be further increased.

[0057] Wherein, the sub-guide portion includes a plurality of discretely arranged protrusions or columnar protrusions; or the sub-guide portion includes a continuously extending rib.

[0058] For example, the protrusions are hemispherical protrusions, and the columnar protrusions are cylindrical protrusions. Fig. 9 and Fig.10 As shown, the sub-guide portion 311 and the sub-guide portion 312 respectively include three protrusions or columnar protrusions, and the protrusions or columnar protrusions of the sub-guide portion 311 and the sub-guide portion 312 correspond to each other one by one. The distance between the first protrusion or columnar protrusion of the sub-guide portion 311 and the sub-guide portion 312 is D1, the distance between the second protrusion or columnar protrusion of the sub-guide portion 311 and the sub-guide portion 312 is D2, and the distance between the third protrusion or columnar protrusion of the sub-guide portion 311 and the sub-guide portion 312 is D3, satisfying D1>D2>D3, that is, along the direction from the proximal end 110 of the sleeve 10 toward 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 the sub-guide portion 311 and the sub-guide portion 312 gradually decreases.

[0059] For example, the sub-guide portion 311 and the sub-guide portion 312 are two convex ribs protruding from the abutment plane 301, and the two convex ribs have a certain angle, so that the width of the space 121 defined between the two convex ribs gradually decreases along the direction from the proximal end 110 of the sleeve 10 toward the distal end 120 of the sleeve 10.

[0060] See also Fig.11 An embodiment of the present application provides an electronic atomizer, comprising a liquid storage chamber 610 for storing a liquid matrix and an atomization assembly 100 as described in any of the above embodiments, wherein the atomization assembly 100 is used to atomize the liquid matrix from the liquid storage chamber 610 to generate an aerosol.

[0061] The electronic atomizer includes a housing 1 and a battery assembly 2. The housing 1 has a receiving space configured to accommodate an atomizer bomb. The battery assembly 2 is electrically connected to the atomizer bomb to provide power for the atomizer bomb. The atomizer bomb includes a housing 61, a top cover 62 and a bottom cover 63. The top cover 62 and the bottom cover 63 are respectively covered at both ends of the housing 61 in the longitudinal direction. The housing 61, the top cover 62 and the 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 a liquid matrix. The liquid matrix reaches the liquid guide 40 directly through the liquid guide 40 or through the liquid inlet 102, and then is heated and atomized by the heating element 20 to produce an aerosol.

[0062] It can be understood that other components of the electronic atomizer can adopt any existing technology, which will not be described in detail here.
