Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an electronic cigarette that achieves oil-core separation through a mouthpiece plug. Background Technology

[0002] Electronic cigarettes use an atomizer coil assembly with an oil inlet, from which the oil tank atomizes the vapor to form smoke. Because the atomizer coil assembly is connected to the mouthpiece and other external parts of the device, leakage can easily occur if the oil supply channel is open when not in use. Therefore, how to separate the oil from the coil before and after use to prevent leakage is a key challenge for electronic cigarette manufacturers. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an electronic cigarette that achieves oil-core separation through a mouthpiece plug, which can achieve oil-core connection or separation by inserting or removing the mouthpiece plug, thus avoiding the problem of oil leakage.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] The electronic cigarette includes an oil tank, an atomizer core assembly, an oil tank sealing silicone, an oil tank support, and an atomizer core support. A mouthpiece is formed at the top of the oil tank. The atomizer core assembly is axially connected inside the oil tank below the mouthpiece. The bottom of the oil tank is sealed with oil tank sealing silicone. The oil tank support is located below the oil tank sealing silicone and is fixedly connected to the oil tank. The bottom of the atomizer core assembly passes through the oil tank sealing silicone and the oil tank support before connecting to the atomizer core support, and has an oil inlet at its lower end. The electronic cigarette also includes a mouthpiece plug and a spring. The spring is sleeved around the atomizer core support, with both ends abutting against the oil tank support and the atomizer core support. When the mouthpiece plug is inserted into the mouthpiece and connected to the top of the atomizer core assembly, the atomizer core assembly is pushed down until the oil inlet is blocked by the oil tank sealing silicone. When the mouthpiece plug is pulled out of the mouthpiece, the spring pushes the atomizer core assembly up until the oil inlet is open above the oil tank sealing silicone.

[0006] The nozzle forms a barrel-shaped part that communicates with the atomizing core assembly; the inner wall of the oil tank corresponding to the bottom end of the barrel-shaped part forms a sliding part for the top end of the atomizing core assembly to slide axially.

[0007] The top of the atomizing core assembly is a rigid structure surrounded by an atomizing core steel tube; a rigid push ring is radially recessed near the top.

[0008] The cigarette holder plug consists of an axially hollow plastic plug and a pull rod; the pull rod consists of a rod-shaped part and a pull rod cap; the outer side of the top of the plastic plug protrudes outward to form upper and lower annular parts corresponding to the pull rod cap; when the rod-shaped part is inserted into the center of the plastic plug and the pull rod cap is sleeved on the outside of the plastic plug, the bottom end of the pull rod cap abuts against the lower annular part, which can drive the plastic plug to move downward; when the bottom end of the pull rod cap hooks with the upper annular part, it can drive the plastic plug to move upward.

[0009] The rod-shaped portion is slightly shorter than the plastic stopper; the bottom end of the plastic stopper bulges outward radially to form a step; the bulge continues outward radially above the step to form a protruding portion.

[0010] After the bottom end of the plastic plug passes through the barrel-shaped part, the step abuts against the push ring, and the protrusion abuts against the top of the atomizing core assembly; the plastic plug moves down, causing the atomizing core assembly to move down; the rod-shaped part of the pull rod passes into the plastic plug, and the bottom end of the pull rod cap abuts against the lower ring-shaped part, expanding the plastic plug, limiting the abutment between the step and the push ring and the abutment between the protrusion and the top of the atomizing core assembly, and forming an abutment between the upper side of the protrusion and the bottom of the barrel-shaped part, stabilizing the axial position of the atomizing core assembly after it moves down.

[0011] The atomizer core support protrudes outward to form an atomizer core support step, and the oil tank support retracts inward to form an oil tank support limiting ring; the upper and lower ends of the spring respectively abut against the atomizer core support step and the oil tank support limiting ring.

[0012] This invention utilizes a plastic stopper and a spring. When the plastic stopper is inserted into the mouthpiece, it pushes the atomizer coil assembly downwards until the oil inlet is sealed by the silicone sealant in the oil tank. When the plastic stopper is removed, the spring pushes the atomizer coil assembly upwards to the open position where the oil inlet is above the silicone sealant in the oil tank. Therefore, the oil inlet can be closed when not in use, achieving coil-oil separation and preventing leakage. When in use, simply remove the plastic stopper to open the oil inlet.

[0021] The following embodiments are descriptions of specific implementations of this application. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of this utility model. All equivalent modifications that can be obtained from the description of the embodiments of this utility model are within the protection scope of this utility model.

[0022] like Figures 1 to 6 As shown, the electronic cigarette of this utility model includes an oil tank 1, an atomizing core assembly 2, an oil tank sealing silicone 3, an oil tank support 4, an atomizing core support 5, a mouthpiece plug 6, and a spring 7. The top of the oil tank 1 forms a mouthpiece 11; the atomizing core assembly 2 is axially connected inside the oil tank 1 below the mouthpiece 11; the bottom of the oil tank 1 is sealed with the oil tank sealing silicone 3. The oil tank support 4 is located below the oil tank sealing silicone 3 and is fixedly connected to the oil tank 1. The bottom end of the atomizing core assembly 2 passes through the oil tank sealing silicone 3 and the oil tank support 4 and is connected to the atomizing core support 5; an oil inlet 21 is provided at the lower end of the atomizing core assembly 2.

[0023] Spring 7 is fitted around atomizer core support 5 and its two ends abut against oil tank support 4 and atomizer core support 5. Specifically, atomizer core support 5 protrudes outward to form atomizer core support step 51, and oil tank support 4 retracts inward to form oil tank support limiting ring 41; the upper and lower ends of spring 7 abut against atomizer core support step 51 and oil tank support limiting ring 41, respectively.

[0024] The nozzle 11 forms a barrel-shaped portion 12 that communicates with the atomizing core assembly 2; the inner wall of the oil tank 1 corresponding to the bottom end of the barrel-shaped portion 12 forms a sliding portion 13 for the top end of the atomizing core assembly 2 to slide axially.

[0025] The top of the atomizing core assembly 2 is a rigid structure surrounded by an atomizing core steel tube; a rigid push ring 22 is set radially inward near the top.

[0026] The mouthpiece plug 6 consists of an axially hollow plastic plug 61 and a pull rod 62. The pull rod 62 consists of a rod-shaped portion 621 and a pull rod cap 622. The outer side of the top of the plastic plug 61 protrudes outward to form an upper annular portion 611 and a lower annular portion 612 corresponding to the pull rod cap 622. The rod-shaped portion 621 is slightly shorter than the plastic plug 61; the bottom end of the plastic plug 61 protrudes radially outward to form a step 613; and continues to protrude radially outward along the top of the step 613 to form a protruding portion 614.

[0027] like Figure 5As shown, after the bottom end of the plastic plug 61 passes through the barrel-shaped part 12, the step 613 abuts against the push ring 22, and the protrusion 614 abuts against the top of the atomizing core assembly 2; the plastic plug 61 moves down, causing the atomizing core assembly 2 to move down; the rod-shaped part 621 of the pull rod 62 passes into the plastic plug 61, and the bottom end of the pull rod cap 622 abuts against the lower ring-shaped part 612, expanding the plastic plug 61, limiting the abutment between the step 613 and the push ring 22 and the abutment between the protrusion 614 and the top of the atomizing core assembly 2, and forming the abutment between the upper side of the protrusion 614 and the bottom of the barrel-shaped part 12, stabilizing the axial position of the atomizing core assembly 2 after it moves down.

[0028] like Figure 6 As shown, when the mouthpiece plug 6 is not inserted into the mouthpiece 11, the spring 7 pushes the atomizer core assembly 2 upward to the top. The top of the atomizer core assembly 2 slides along the sliding part 13 to the top, and at the same time abuts against the bottom of the barrel-shaped part 12. The oil inlet 21 is located above the oil tank sealing silicone 3; the e-liquid in the oil tank 1 can enter the atomizer core assembly 2. The plastic plug 61 is inserted; after the bottom of the plastic plug 61 passes through the barrel-shaped part 12, the step 613 abuts against the push ring 22; at the same time, the protrusion 614 abuts against the top of the atomizer core assembly 2. The plastic plug 61 is pushed in and moved downward, causing the atomizer core assembly 2 to move downward; when the plastic plug 61 is fully inserted (when the lower ring part 612 abuts against the top of the mouthpiece 11); the atomizer core assembly 2 moves downward to the state where the oil inlet 21 is blocked by the oil tank sealing silicone 3. Then, the rod-shaped portion 621 of the lever 62 is inserted into the plastic stopper 61, and the bottom end of the lever cap 622 abuts against the lower ring portion 612. The rod-shaped portion 621 of the lever 62 expands the plastic stopper 61, limits the contact between the step 613 and the push ring 22, and the contact between the protrusion 614 and the top of the atomizing core assembly 2, and forms the contact between the upper side of the protrusion 614 and the bottom of the barrel portion 12, stabilizing the axial position of the atomizing core assembly 2 after it moves down.

[0029] like Figure 7 As shown, pull out the mouthpiece plug 6 to remove the electronic cigarette. Figure 4 When switching from the coil-separated state to the usable coil-connected state, the lever 62 is first pulled outward until the bottom end of the lever cap 622 hooks with the upper ring 611. As the lever 62 is pulled out, the plastic plug 61 is pulled outward. As the mouthpiece plug 6 is pulled out, the atomizer coil assembly 2 moves upward under the restoring force of the compression spring 7. When the mouthpiece plug 6 is fully pulled out, the top of the atomizer coil assembly 2 presses against the bottom end of the barrel 12, defining the position of the atomizer coil assembly 2. At this time, the oil inlet 21 is located above the oil tank sealing silicone 3; e-liquid can enter the atomizer coil assembly 2; the electronic cigarette can be used.

[0030] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The structure of the remaining parts of the electronic cigarette is unrelated to the implementation of the aforementioned scheme; it will not be described in detail here.
