A nested electronic cigarette atomizing core structure

Abstract

This utility model provides a nested electronic cigarette atomizing core structure, relating to the field of atomizing core technology. It includes an outer cylinder and an absorbent strip. A rotating plate is rotatably connected to the inner wall of the outer cylinder. A porous ceramic cylinder is fixedly connected to the lower end of the rotating plate. A downward pressure limiting bracket is fixedly connected to the surface of the porous ceramic cylinder. A heating plate is disposed inside the outer cylinder. An upward pressure limiting bracket is fixedly connected to the surface of the heating plate. The ends of the downward and upward pressure limiting brackets have guide arc surfaces. The inner sides of the downward and upward pressure limiting brackets are slidably connected to the absorbent strip. By fixing and rotating the middle section of the absorbent strip through the downward pressure limiting bracket, the absorbent strip quickly wraps around the heating plate.

Description

Technical Field

[0001] This utility model relates to the technical field of atomizing cores, specifically a nested electronic cigarette atomizing core structure. Background Technology

[0002] The atomizing coil is the core functional component of an e-cigarette. Its design and performance directly determine the user experience, safety, and core functionality of the e-cigarette. Through the capillary effect of the oil-conducting material, the e-liquid is continuously transported from the oil storage tank to the heating element, preventing the heating coil from burning dry. According to the public announcement (CN219288758U), an atomizing core and electronic cigarette are disclosed. This technology discloses "a heating element and wicking cotton, wherein the heating element is embedded in the wicking cotton to heat the e-liquid inside the wicking cotton, the wicking cotton is a roll material, and the free edge of the wicking cotton extends along a first direction; an atomizing tube has a receiving cavity for accommodating the wicking cotton and an oil inlet connecting the receiving cavity to the outside, and further includes a first tube segment, a connecting part and a second tube segment connected in sequence, wherein the length of the oil inlet along the first direction is not greater than the length of the free edge of the wicking cotton, or the width of the oil inlet perpendicular to the first direction is not greater than the thickness of the wicking cotton; or, the connecting part at least partially covers the free edge of the wicking cotton, etc., which has the technical effect of simple atomizing core structure, wicking cotton not easily flipping, maximizing the oil inlet area, improving oil guiding performance, and improving the consistency and stability of product processing output." In the aforementioned patent, the wicking cotton often becomes charred on the surface after absorbing e-liquid and being heated by the heating element due to prolonged exposure to high temperatures. This reduces the oil absorption efficiency and causes the atomizer core's vapor production capacity to decline. Furthermore, replacing the wicking cotton is a cumbersome process that can easily damage the heating element.

[0003] Therefore, this utility model provides a nested electronic cigarette atomizing core structure. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 - Figure 4As shown, this embodiment provides a technical solution: a nested electronic cigarette atomizing core structure, including an outer cylinder 1 and an oil-absorbing cotton strip 2. A rotating plate 3 is rotatably connected to the inner wall of the outer cylinder 1, and the inner circumference of the outer cylinder 1 is equal to the outer circumference of the rotating plate 3. A porous ceramic cylinder 4 is fixedly connected to the lower end of the rotating plate 3, and a downward pressure limiting frame 5 is fixedly connected to the surface of the porous ceramic cylinder 4. A heating plate 6 is provided inside the outer cylinder 1. The heating plate 6 is arc-shaped, and an upward pressure limiting frame 7 is fixedly connected to the surface of the heating plate 6. Two upward pressure limiting frames 7 are provided to limit the oil-absorbing cotton strip 2 to the outer wall of the heating plate 6. The ends of the downward pressure limiting frame 5 and the upward pressure limiting frame 7 are provided with guide arc surfaces 8 to guide the insertion of the oil-absorbing cotton strip 2. The inner sides of the downward pressure limiting frame 5 and the upward pressure limiting frame 7 are respectively connected to the oil-absorbing cotton strip. 2. Sliding connection: The surfaces of the porous ceramic cylinder 4 and the heating plate 6 are slidably connected to the oil-absorbing cotton strip 2. The upper ends of the outer cylinder 1 and the rotating plate 3 are provided with vent holes 9. The two ends of the oil-absorbing cotton strip 2 are kept on the outside of the outer cylinder 1. The middle part is wrapped around the outer wall of the heating plate 6 by the upper pressure limiting frame 7. Then the outer cylinder 1 is pressed down with the rotating plate 3. The middle section of the oil-absorbing cotton strip 2 is fixed between the lower pressure limiting frame 5 and the porous ceramic cylinder 4 by the lower pressure limiting frame 5. When the rotating plate 3 is rotated, the oil-absorbing cotton strip 2 can rotate with the rotating plate 3 and thus roll up inside the heating plate 6 and stick tightly to the inner wall of the heating plate 6. Through this mechanism, the oil-absorbing cotton strip 2 can be quickly wrapped around the heating plate 6. That is, after the surface of the oil-absorbing cotton strip 2 is charred and its oil-conducting ability decreases after long-term heating, the operation of quickly replacing the oil-absorbing cotton strip 2 can be realized.

[0024] like Figure 1 - Figure 3 As shown: The upper end of the rotating plate 3 is fixedly connected to the rotating shaft 10, and the surface of the rotating shaft 10 is threaded with a positioning ring 11. The rotating shaft 10 and the positioning ring 11 are adapted to each other. The lower end of the positioning ring 11 is slidably connected to the outer cylinder 1. After the rotating plate 3 rotates, the positioning ring 11 rotates on the rotating shaft 10 to squeeze the outer cylinder 1, thereby achieving the positioning of the angle of the rotating plate 3.

[0025] like Figure 1 - Figure 3 As shown: The inner cylinder 12 is slidably connected to the inner wall of the outer cylinder 1. The inner circumference of the outer cylinder 1 is equal to the outer circumference of the inner cylinder 12. Positioning grooves 13 are respectively opened on the surface of the outer cylinder 1 and the inner cylinder 12. The angles of the positioning grooves 13 are corresponding. An air inlet hole 14 is opened on the surface of the inner cylinder 12. The outer cylinder 1 and the inner cylinder 12 are slidably connected to the oil-absorbing cotton strip 2 through the positioning grooves 13. The oil-absorbing cotton strip 2 enters and exits the interior of the outer cylinder 1 and the inner cylinder 12 through the positioning grooves 13, and is fixed after the outer cylinder 1 and the inner cylinder 12 are positioned relative to each other.

[0026] like Figure 1 - Figure 3As shown: The heating plate 6 has conductive pins 15 fixedly connected to both ends, and insulating sleeves 16 are fixedly connected to the surface of the conductive pins 15. Current is introduced into the interior of the heating plate 6 through the conductive pins 15, so that the heating plate 6 can be powered to heat the oil-absorbing cotton strip 2.

[0027] like Figure 3 - Figure 4 As shown: A limiting ring 17 is fixedly connected to the surface of the insulating sleeve 16. The lower end of the limiting ring 17 is slidably connected to the inner cylinder 12. A slot 18 is provided at the lower end of the inner cylinder 12. The inner circumference of the slot 18 is smaller than the outer circumference of the limiting ring 17, so that the insulating sleeve 16 is fixed on one side after insertion. The surface of the insulating sleeve 16 is slidably connected to the inner cylinder 12 through the slot 18. The outer circumference of the insulating sleeve 16 is equal to the inner circumference of the slot 18. A fixing ring 19 is threadedly connected to the surface of the insulating sleeve 16. The insulating sleeve 16 and the fixing ring 19 are adapted to each other. After the insulating sleeve 16 is inserted from the inside of the inner cylinder 12 to the outside through the slot 18, the fixing ring 19 is rotated to fix it, so that the conductive pin 15 can be quickly disassembled and replaced after long-term aging.

[0028] like Figure 1 - Figure 3 As shown: An elastic metal plate 20 is fixedly connected to the surface of the inner cylinder 12. There are two elastic metal plates 20. An arc-shaped buckle 21 is fixedly connected to the surface of the elastic metal plate 20. The outer side of the arc-shaped buckle 21 is arc-shaped. A pressing groove 22 is opened on the surface of the inner cylinder 12. When the arc-shaped buckle 21 is pressed, the arc-shaped buckle 21 transmits force to the elastic metal plate 20, causing the elastic metal plate 20 to deform. This allows the elastic metal plate 20 and the arc-shaped buckle 21 to slide into the pressing groove 22 respectively, thus avoiding obstruction of the inner cylinder 12 from being inserted into the outer cylinder 1.

[0029] like Figure 1 - Figure 3 As shown: The outer cylinder 1 has a slot 23 on its surface. The arc-shaped buckle 21 is slidably connected to the outer cylinder 1 through the slot 23. The outer circumference of the arc-shaped buckle 21 is equal to the inner circumference of the slot 23. When the side end of the arc-shaped buckle 21 is aligned with the slot 23, the arc-shaped buckle 21, which is no longer compressed, is pushed into the slot 23 by the elastic metal plate 20, thereby fixing the outer cylinder 1 and the inner cylinder 12. When the arc-shaped buckle 21 is pressed again so that the arc surface of the arc-shaped buckle 21 contacts the inner edge of the slot 23, the inner cylinder 12 is pulled down. The slot 23 compresses the arc-shaped buckle 21 to move inward and deforms the elastic metal plate 20, so that the inner cylinder 12 can be quickly removed for internal parts to be inspected and replaced.

[0030] Working principle: like Figure 1 - Figure 4 As shown: In use: First, the insulating sleeve 16 is inserted from the inside of the inner cylinder 12 through the slot 18 to the outside. Then, the fixing ring 19 is rotated to fix it, so that the conductive pin 15 and the heating plate 6 are fixed inside the inner cylinder 12. The middle of the oil-absorbing cotton strip 2 is wrapped around the outer wall of the heating plate 6 by the upper pressure limiting frame 7. Then, the outer cylinder 1 is pressed down with the rotating plate 3. The middle section of the oil-absorbing cotton strip 2 is fixed between the lower pressure limiting frame 5 and the porous ceramic cylinder 4 by the lower pressure limiting frame 5. The rotating plate 3 is rotated, and the oil-absorbing cotton strip 2 can rotate with the rotating plate 3 to roll up inside the heating plate 6 and stick tightly to the inner wall of the heating plate 6. After the rotating plate 3 rotates, the positioning ring 11 is rotated on the rotating shaft 10 to squeeze the outer cylinder 1 and position the angle of the rotating plate 3. Through this mechanism, the oil-absorbing cotton strip 2 can be quickly wrapped around the heating plate 6. That is, after the surface of the oil-absorbing cotton strip 2 is charred and its oil-conducting ability decreases after long-term heating, the oil-absorbing cotton strip 2 can be quickly replaced. After inserting the inner cylinder 12 into the outer cylinder 1, when the side end of the arc-shaped buckle 21 is aligned with the slot 23, the arc-shaped buckle 21, which is no longer compressed, is pushed into the slot 23 by the elastic metal plate 20, thereby fixing the outer cylinder 1 and the inner cylinder 12. When the arc-shaped buckle 21 is pressed again so that the arc surface of the arc-shaped buckle 21 contacts the inner edge of the slot 23, the inner cylinder 12 is pulled down. The slot 23 compresses the arc-shaped buckle 21 to move inward and deforms the elastic metal plate 20, so that the inner cylinder 12 can be quickly removed for inspection and replacement of internal parts.
