[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0040] See also Figures 1 to 8 The electronic cigarette cartridge 10 of one embodiment of the present invention includes a housing 100, a sealing mounting base 200, an air duct 300, an atomizing core 400, and two conductive posts 700. The atomizing core 400 is disposed within the air duct 300; the housing 100 is provided with two electrode mounting slots 101. The inner wall of each electrode mounting groove 101 is provided with a through hole 1011 and a plug hole 1012; the sealing mounting base 200 is provided with a fixing groove 201, an air hole 202 and two wire holes 203, and the air hole 202 and the two wire holes 203 are all connected to the fixing groove 201; one end of the air guide tube 300 is located in the fixing groove 201 and connected to the sealing mounting base 200; the atomizer core 400 is provided with an atomization chamber 4101 connected to the air hole 202; wires 510 extend from both ends of the heating element 500 of the atomizer core 400, each wire 510 is inserted into the corresponding plug hole 1012 through the corresponding wire hole 203 and the corresponding through hole 1011, and each conductive column 700 is inserted into the plug hole 1012 of the corresponding electrode mounting groove 101 to press against the corresponding wire 510.

[0041] In this embodiment, wires 510 extend from both ends of the heating element 500. Each wire 510 passes through the corresponding wire hole 203, the through-hole 1011, and the plug-in hole 1012, and abuts against the inner wall of the plug-in hole 1012 and the conductive column 700. This ensures a stable connection between the heating element 500 and the conductive column 700, avoids deformation and short-circuit problems, and improves the reliability and safety of the electronic cigarette. Furthermore, a through-hole 1011 and a plug-in hole 1012 are provided in the electrode mounting groove 101. After passing through the through-hole 1011, the wire 510 is bent toward the plug-in hole 1012 and passes through the plug-in hole 1012, ensuring that the wire 510 can be firmly connected to the conductive column 700. Furthermore, the conductive post 700 presses and fixes the wire 510 so that the wire 510 can fully contact the inner wall of the plug hole 1012 and the conductive post 700 itself, thereby further improving the stability and reliability of the connection between the conductive post 700 and the wire 510.

[0042] like Figures 1 to 3 and Figure 8 As shown, in one embodiment, the electrode mounting groove 101 is located on the side of the housing 100 that abuts the cigarette rod 800. It is understandable that the electrode mounting groove 101 is opened on the side and abuts the corresponding component on the cigarette rod 800, and the power supply component is set in the cigarette rod 800. This can prevent the tobacco oil from flowing directly to the conductive column 700 through the heating element 500, thereby preventing the tobacco oil from leaking between the electronic cigarette cartridge 10 and the cigarette rod 800 through the electrode mounting groove 101. Specifically, in this embodiment, the conductive column 700 has the property of being attracted by a magnet and also has conductive properties.

[0043] like Figure 2 As shown, in one embodiment, the atomizer core 400 includes a heating element 500 and a liquid-conducting medium 420 . The liquid-conducting medium 420 is coated on the heating element 500 , and the liquid-conducting medium 420 is installed in the air guide tube 300 .

[0044] like Figure 2 As shown, in one embodiment, the atomizer core 400 further includes an atomizer bracket 410 , and the liquid-conducting medium body 420 is installed in the air guide tube 300 through the atomizer bracket 410 .

[0045] Specifically, in this embodiment, the liquid-conducting medium body 420 is a non-woven fabric or oil-conducting cotton, which needs to be used with the atomizing bracket 410 to fix the non-woven fabric or oil-conducting cotton to prevent the non-woven fabric or oil-conducting cotton from being deformed during use, thereby preventing the heating element from being pulled and deformed or separated from the liquid-conducting medium body 420 to affect the atomization effect.

[0046] Furthermore, in another embodiment, the liquid-conducting medium 420 is a ceramic core, which does not need to be fixed to the atomizer bracket 410 and can be integrally formed with the heating element 500. The ceramic core is not easily broken or burnt, ensuring the fullness of the vapor and the consistency of the taste.

[0047] like Figure 2 and Figure 6 As shown, in one embodiment, the atomizer core 400 further includes a wire fixing member 430. The wire fixing member 430 is located below the liquid-conducting medium body 420 and abuts against the inner wall of the atomizer bracket 410. The side wall of the wire fixing member 430 is provided with a plurality of guide grooves 4301. The wires 510 at both ends of the heating element 500 are respectively located in any two guide grooves 4301. It can be understood that the wire fixing member 430 is located at the bottom of the atomizer bracket 410. The wires 510 extend downward into the wire hole 203 through the guide grooves 4301. The guide grooves 4301 can separate the wires 510 to prevent short circuits; at the same time, the wires 510 are fixed between the guide grooves 4301 and the inner wall of the atomizer bracket 410 to prevent the heating element 500 from being pulled and deformed during assembly.

[0048] like Figure 6 As shown, in one embodiment, the wire fixing member 430 is formed with an abutting protrusion 431, which abuts against the bottom of the heating element 500. Specifically, in this embodiment, the abutting protrusion 431 cooperates with the atomizing bracket 410 and the oil-conducting medium 420 to support and fix the heating element 500, thereby fixing the heating element 500 and preventing it from being pulled and deformed during assembly.

[0049] like Figure 4 and Figure 5 As shown, in one embodiment, the cross-sectional area of the wire hole 203 gradually decreases from the end adjacent to the wire fixing member 430 to the end away from the wire fixing member 430, that is, the upper part of the wire hole 203 is larger and the lower part is smaller, which is convenient for guiding the wire 510 into the wire hole 203 and at the same time can ensure the stability of the installation of the wire 510.

[0050] like Figure 5 As shown, in one embodiment, the wire hole 203 is filled with a filling colloid (not shown) to reduce the space inside the wire hole 203, thereby preventing the wire 510 from being displaced in the wire hole 203, thereby preventing the heating element 500 from being pulled and deformed.

[0051] Furthermore, in this embodiment, the filling colloid is formed by curing latex sealant, so that the latex sealant has insulation sealing properties and the ability to adapt to deformation, thereby ensuring stable electrical performance and good sealing of the wire 510.

[0052] like Figure 4 and Figure 5 As shown, in one embodiment, a guide protrusion 210 is provided at the bottom of the sealing mounting base 200. The guide protrusion 210 has a wire side (not shown) facing the through hole 1011 to guide the wire 510 extending from the bottom of the sealing mounting base 200 into the through hole 1011. It is understood that the guide protrusion 210 is located between the air hole 202 and the wire hole 203 to prevent the wire hole 203 from overflowing and contaminating or clogging the air hole when the colloid is filled; at the same time, the guide protrusion 210 can guide the wire 510 passing through the wire hole 203 to bend toward the electrode mounting groove 101.

[0053] like Figure 2 and Figure 3 As shown, in one embodiment, the electrode mounting slot 101 further defines a wire threading slot 103, which is connected to the insertion hole 1011 and the plug hole 1012. Specifically, in this embodiment, the insertion hole 1101 is located above the plug hole 1102. The wire 510 passes through the insertion hole 1101, is bent, and then passes through the plug hole 1102. The bent portion is located within the insertion slot 103. This prevents the bent portion from abutting and squeezing the conductive post 700, thereby ensuring the secure installation of the conductive post 700 and the stability of the electrical performance between the wire 510 and the conductive post 700.

[0054] like Figure 2 As shown in one embodiment, the electronic cigarette cartridge 10 further includes two magnetic components 600. Magnetic mounting slots 105 are respectively provided at both ends of the housing 100. The magnetic components 600 are installed in the magnetic mounting slots 105 and are used to connect to the cigarette rod 800. It is understood that the magnetic connection method does not require a physical connection through a mechanical structure, thus avoiding problems such as circuit short circuits or poor contact caused by plugging and unplugging.

[0055] like Figure 2 As shown, in one embodiment, the atomizer core 400 further includes a fixing ring 440, which abuts against the inner wall of the air guide tube 300, and one end of the atomizer bracket 410 is disposed within the fixing ring 440. It is understood that the fixing ring 440 is used to fix the atomizer bracket 410. The fixing ring 440 is located in the fixing groove 201, which can ensure the accurate installation position of the atomizer bracket 410; at the same time, it can prevent the atomizer bracket 410 from moving, thereby preventing the heating element 500 from moving and deforming, thereby preventing the connection between the wire 510 and the conductive column 700 from being damaged.

[0056] like Figure 2 and Figure 7As shown in one embodiment, the heating element 500 is a mesh heating wire. It can be understood that the liquid-conducting medium 420 is coated on the mesh heating wire, so that the e-liquid is evenly distributed on the surface of the mesh heating wire. At the same time, the mesh structure of the heating wire increases the heating area, thus quickly producing a balanced and long-lasting smoke effect.

[0057] Compared with the prior art, the present disclosure has at least the following advantages:

[0058] 1. Wires extend from both ends of the heating element. Each wire passes through the corresponding wire hole, through-hole, and plug hole, and contacts the inner wall of the plug hole and the conductive column. This ensures a stable connection between the heating element and the conductive column, avoiding deformation and short circuit issues, and improving the reliability and safety of the e-cigarette.

[0059] 2. Set a through hole and a plug hole in the electrode mounting groove. After the wire passes through the through hole, bend it toward the plug hole and pass it through the plug hole to ensure that the wire can be firmly connected to the conductive column.

[0060] 3. The conductive post fixes the wire by pressing it, so that the wire can fully contact the inner wall of the plug hole and the conductive post itself, thereby further improving the stability and reliability of the connection between the conductive post and the wire.

[0061] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
