Leads are connected to both ends of the heating coil, extending from the inner hole of the mounting base to electrically connect to the positive and negative poles of a power source, respectively. When assembling the atomizer core, since the lead wires extend perpendicular to the winding axis of the heating coil, after one end of the lead wire is connected to the heating coil, force is applied to the other end of the same lead wire to bend it.

[0004] The technical problem to be solved by the present invention is that, in view of the problem that the existing atomizer core easily causes the heating coil to move when the lead is pulled, resulting in the heating coil not heating in the center, a fixing seat, an atomizer core and an electronic cigarette are provided.

[0013] Optionally, the fixing seat is provided with two liquid inlet grooves distributed opposite to each other along the radial direction of the inner hole, and the two liquid inlet grooves are suitable for receiving the two ends of the heating coil of the atomizer core respectively;

[0029] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figures 1 to 4 As shown, an embodiment of the present invention provides an atomizer core, comprising a heating coil 5 and a fixing base 1. The heating coil 5 is placed horizontally in the fixing base 1, and leads 10 are connected to both ends of the heating coil 5. The heating coil 5 is wound in a spring shape, and the winding axis of the heating coil 5 is perpendicular to the lead-out direction of the lead 10. The "horizontal" refers to the direction perpendicular to the axial direction of the inner hole of the fixing base 1.

[0031] like Figure 6 and Figure 7As shown, the fixing base 1 has an inner hole, and a first guide hole 11 and a second guide hole 12 are provided in the inner hole of the fixing base 1 along its axial direction. The first guide hole 11 is provided near one end of the heating coil 5 in the circumferential direction of the inner hole, and the second guide hole 12 is provided near the other end of the heating coil 5 in the circumferential direction of the inner hole. The term "close" means that the circumferential angle between the first guide hole 11 and the one end of the heating coil 5 is less than 90°, and the circumferential angle between the second guide hole 12 and the other end of the heating coil 5 is less than 90°.

[0032] The two lead wires 10 pass through the first guiding hole 11 and the second guiding hole 12 respectively. The first guiding hole 11 and the second guiding hole 12 are suitable for guiding and pulling the two lead wires 10 along the axial direction of the inner hole respectively.

[0033] It should be noted that one end of one lead wire 10 is connected to one end of the heating coil 5, and the other end is electrically connected to the positive electrode of the power supply, forming a positive lead wire. One end of another lead wire 10 is connected to the other end of the heating coil 5, and the other end of the other lead wire 10 is electrically connected to the negative electrode of the power supply, forming a negative lead wire, thereby forming a closed circuit. When the heating coil 5 is powered on, it can heat the atomized liquid and generate smoke.

[0034] When assembling the atomizer core, first, insert the two lead wires 10 into the first guide hole 11 and the second guide hole 12 respectively, and connect one end of the two lead wires 10 to the two ends of the heating coil 5 respectively. Then, apply force to the other end of the same lead wire 10, and pull the corresponding lead wire 10 along the hole wall of the first guide hole 11 and the hole wall of the second guide hole 12 along the axial direction of the inner hole to bend the lead wire 10.

[0035] Because the first guide hole 11 and the second guide hole 12 can guide the lead wire 10 to be pulled axially along the inner hole, the pulling direction is perpendicular to the winding axis direction of the heating coil 5. Moreover, the first guide hole 11 is arranged near one end of the heating coil 5 in the circumferential direction of the inner hole, and the second guide hole 12 is arranged near the other end of the heating coil 5 in the circumferential direction of the inner hole. The inclination angle of the lead wire 10 when passing through the first guide hole 11 and the second guide hole 12 is relatively small, thereby reducing the component force of the lead wire 10 on the heating coil 5 along the winding axis direction of the heating coil 5 when the lead wire 10 is pulled axially along the inner hole, thereby reducing the situation where the heating coil 5 moves along its winding axis direction when the lead wire 10 is pulled, resulting in non-centered heating.

[0036] The so-called "movement of the heating coil 5" is because one end of the lead wire 10 is connected to the end of the heating coil 5. When the lead wire 10 is pulled obliquely, the component force along the winding axis direction of the heating coil 5 will drive the heating coil 5 to move to one side as a whole, causing the overall position of the heating coil 5 to change, and will also drive the various turns of the heating coil 5 to move closer, causing the interval between adjacent turns of the heating coil 5 to change, which can easily affect the centrality of the heating of the heating coil 5.

[0037] Moreover, compared to the existing method where the two leads 10 are randomly arranged in the inner hole of the fixing base 1, which easily leads to confusion and confusion between the positive lead and the negative lead, the atomizer core of the present invention utilizes the first guide hole 11 and the second guide hole 12 to respectively limit the positions of the two leads 10, making it easier to distinguish the positive lead from the negative lead.

[0038] In the atomizer core of the present invention, the first guide hole 11 and the second guide hole 12 provided in the inner hole of the fixing base 1 can respectively guide the pulling of the two lead wires 10 along the axial direction of the inner hole, so that the direction of pulling the lead wires 10 is perpendicular to the winding axis direction of the heating coil 5. Moreover, the first guide hole 11 is provided near one end of the heating coil 5 in the circumferential direction of the inner hole, and the second guide hole 12 is provided near the other end of the heating coil 5 in the circumferential direction of the inner hole. The inclination angle of the lead wire 10 when passing through the first guide hole 11 and the second guide hole 12 is relatively small, thereby reducing the component of force exerted by the lead wire 10 on the heating coil 5 along the winding axis direction of the heating coil 5 when the lead wire 10 is pulled along the axial direction of the inner hole, thereby reducing the situation where the heating coil 5 moves along its winding axis direction when the lead wire 10 is pulled, resulting in non-centered heating.

[0039] In one embodiment, if Figure 4 and Figure 5 As shown, the atomizer core also includes a liquid phase absorber 8, which is placed inside the heating coil 5. The liquid phase absorber 8 is used to absorb the atomized liquid. The heating coil 5 is used to heat the atomized liquid to vaporize the atomized liquid. The liquid phase absorber is usually made of fiber or cotton, capable of absorbing the atomized liquid and having heat resistance.

[0040] In one embodiment, if Figure 6 As shown, the first guide hole 11 is located directly below one end of the heating coil 5, and the second guide hole 12 is located directly below the other end of the heating coil 5, so that the two lead wires 10 are respectively inserted into the first guide hole 11 and the second guide hole 12 along the axial direction of the inner hole, so as to further reduce the situation where the heating coil 5 moves along its winding axis and causes the heating to be not centered.

[0041] In other embodiments, the circumferential positions of the first guide hole 11 and the second guide hole 12 can be adjusted according to actual needs. Of course, the closer the first guide hole 11 and the second guide hole 12 are to the two end portions of the heating coil 5 in the circumferential direction of the inner hole, the better the effect of reducing the movement of the heating coil 5 when the lead wire 10 is bent.

[0042] In one embodiment, the first guide hole 11 and the second guide hole 12 are relatively distributed along the radial direction of the inner hole to increase the circumferential spacing between the first guide hole 11 and the second guide hole 12, which is conducive to distinguishing the two leads 10 passing through the first guide hole 11 and the second guide hole 12.

[0043] In one embodiment, if Figure 7 As shown, the fixing seat 1 includes a seat body 15, a first lead seat 13 and a second lead seat 14. The first lead seat 13 and the second lead seat 14 are connected to the inner hole wall of the seat body 15. The seat body 15 is used to accommodate the heating coil 5. The first guiding hole 11 is set on the first lead seat 13, and the second guiding hole 12 is set on the second lead seat 14, so that the first guiding hole 11 and the second guiding hole 12 are exposed in the inner hole of the fixing seat 1, so that the two leads 10 are convenient to pass through the first guiding hole 11 and the second guiding hole 12 respectively.

[0044] In one embodiment, the first guiding hole 11 and the second guiding hole 12 are waist-shaped holes, and the waist-shaped holes extend along the circumference of the inner hole.

[0045] In one embodiment, the first lead holder 13 and the second lead holder 14 are integrally formed with the holder body 15 , which simplifies the processing technology and reduces the processing cost.

[0046] In other embodiments, the first lead holder 13 and / or the second lead holder 14 can be fixed to the holder body 15 by bonding, clamping, riveting or other mechanical connection methods.

[0047] In one embodiment, the first lead holder 13 extends circumferentially around the first guide hole 11, and the second lead holder 14 extends circumferentially around the second guide hole 12, so that the first lead holder 13 and the second lead holder 14 form a circumferentially closed structure, preventing the lead 10 from escaping from the first lead holder 13 or the second lead holder 14, thereby improving the reliability of the first lead holder 13 and the second lead holder 14 in guiding and limiting the corresponding lead 10.

[0048] In one embodiment, the cross-section of the first lead seat 13 and the second lead seat 14 is waist-shaped, and both the first lead seat 13 and the second lead seat 14 extend along the axial direction of the inner hole of the fixing seat 1 .

[0049] In one embodiment, the first lead holder 13 is chamfered at the top of the first guide hole 11; the second lead holder 14 is chamfered at the top of the second guide hole 12 to prevent the edges of the hole walls of the first lead holder 13 and the second lead holder 14 from wearing the lead 10 when pulling the lead 10.

[0050] In one embodiment, if Figure 7 As shown, the fixing base 1 is provided with two liquid inlet grooves 16 that are oppositely distributed along the radial direction of the inner hole. The two liquid inlet grooves 16 receive the two ends of the heating coil 5 of the atomizer core respectively.

[0051] The first guide hole 11 is provided around the inner hole, adjacent to one of the liquid inlet grooves 16. The second guide hole 12 is provided around the inner hole, adjacent to the other liquid inlet groove 16. The atomizer core is located in the liquid phase receiving portion of the electronic cigarette (not shown). The atomized liquid in the liquid phase receiving portion can flow through the liquid inlet groove 16 to the liquid phase absorber 8.

[0052] When processing the fixing seat 1, the first guide hole 11 and the second guide hole 12 can be positioned and processed according to the position of the liquid inlet groove 16, so that after the two ends of the heating coil 5 are placed in the liquid inlet groove 16, the first guide hole 11 and the second guide hole 12 are respectively close to the two ends of the heating coil 5, which is convenient for positioning and processing the first guide hole 11 and the second guide hole 12.

[0053] In one embodiment, the atomizer core further includes an insulating ring 9, an air inlet seat 2 and a gas inlet portion 7. The fixing seat 1 is pressed onto the air inlet seat 2 from the top end of the air inlet seat 2. The insulating ring 9 is sleeved outside the gas inlet portion 7 and inserted into the bottom end of the air inlet seat 2.

[0054] The lead wire 10 passing through the first guide hole 11 passes through the gas inlet portion 7, and the lead wire 10 passing through the second guide hole 12 passes through the gas inlet seat 2. The two lead wires 10 are respectively located on the inner and outer sides of the insulating ring 9, so that the insulating ring 9 can insulate the two lead wires 10 and can also better distinguish the positive lead from the negative lead.

[0055] In one embodiment, a through hole is provided at the bottom end of the air inlet seat 2, and the insulating ring 9 is sealed and installed in the through hole. A connecting hole is provided in the gas inlet portion 7, and the connecting hole is connected to the inner hole of the fixed seat 1, so that air can flow to the liquid phase absorption component 8 through the connecting hole.

[0056] In one embodiment, a guide portion 71 protruding toward the heating coil 5 is provided on the side of the gas inlet portion 7 close to the heating coil 5, and the connecting hole passes through the guide portion 71 to extend the length of the connecting hole, thereby reducing the dispersion of air after flowing into the fixing seat 1, and facilitating the air to flow along the axial direction of the connecting hole toward the liquid absorption component 8.

[0057] In one embodiment, if Figure 4 and Figure 5 As shown, the atomizer core also includes an outer tube 4 and a filter 3. The filter 3 is mounted outside the fixing base 1. The end surface of the air inlet base 2 supports the filter 3. The outer tube 4 is mounted outside the filter 3 and is pressed onto the air inlet base 2. The outer tube 4 has a plurality of spaced liquid holes on its wall. The atomized liquid in the liquid phase receiving portion flows into the fixing base 1 through the liquid holes. The filter 3 is used to store the e-liquid.

[0058] In one embodiment, the atomizer core further includes a cover 6, which covers the opening of the outer tube 4 away from the air inlet seat 2. The heating coil 5 heats the atomizing liquid to generate smoke that flows through the flow channel in the cover 6 to the mouthpiece of the electronic cigarette (not shown in the figure).

[0059] In other embodiments, the first guiding hole 11 and the second guiding hole 12 may be arranged at a certain angle, such as 90°, 120°, etc.

[0060] In other embodiments, a support structure can be set in the inner hole of the fixed base 1 to support the heating coil 5. The support structure can be two bosses, which respectively support the two ends of the heating coil 5. The support structure can also be a support grid connected to the inner hole wall of the fixed base 1, and the heating coil 5 is placed on the support grid.

[0061] In other embodiments, the fixing seat 1 may only include a seat body 15, and the first guide hole 11 and the second guide hole 12 may be set in the side wall of the seat body 15, and both ends of the first guide hole 11 and the second guide hole 12 pass through the hole wall of the inner hole of the seat body 15, so that the two leads 10 can respectively pass through the first guide hole 11 and the second guide hole 12.

[0062] In other embodiments, the first guiding hole 11 and / or the second guiding hole 12 may be a circular hole, a polygonal hole, an elliptical hole or other irregularly shaped holes.

[0064] In other embodiments, the chamfers of the first lead holder 13 and / or the second lead holder 14 may be omitted, and flexible materials such as rubber pads, nylon cloth, etc. may be laid or adhered on the first lead holder 13 and / or the second lead holder 14 to prevent the lead 10 from contacting and rubbing against the edges.

[0065] In addition, an embodiment of the present invention provides a fixing base 1 , the structure of which is the same as that of the fixing base 1 in any of the above embodiments, and will not be described in detail here.
