Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizing core technology, specifically a low-cost atomizing core structure based on a stepped multi-segment heating mesh. Background Technology
[0002] In electronic atomizers, the atomizer coil (also known as the atomizer core or atomizer head) is one of the core components, responsible for converting liquid e-liquid into inhalable vapor. It is generally made of materials such as nickel, cobalt, copper, and stainless steel, and is used to heat the e-liquid.
[0003] To achieve the above functions, a prior art Chinese patent (publication number: CN216701684U) discloses an atomizing core, which includes a fixing base and a conductive heating element. The fixing base has a mounting positioning surface, a first abutment surface, and a second abutment surface, which are located on both sides of the fixing base, and neither the first abutment surface nor the second abutment surface is coplanar with the mounting positioning surface. The conductive heating element includes a heating part, a first conductive part, and a second conductive part, which are respectively connected to both ends of the heating part. The heating part abuts against the mounting positioning surface. The first conductive part is bent at least on the first abutment surface, and the second conductive part is bent at least on the second abutment surface. Because the conductive heating element is fixed to the fixing base by bending, the fixed connection between the conductive heating element and the fixing base is relatively simple, thus simplifying the overall structure of the atomizing core. The atomizing core can be manufactured and assembled by stamping, and mass production of the atomizing core is easily achieved, thereby improving the production efficiency of a single atomizing core.
[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: the atomizing core in an electronic atomizer generally converts e-liquid into vapor through high temperature, and the amount of e-liquid evaporation is controlled by the power of the heating mesh inside the atomizing core. Existing heating meshes will heat up simultaneously when powered on, making it difficult to control the heating area of the heating mesh. Utility Model Content
[0005] The purpose of this invention is to provide a low-cost atomizing core structure based on a stepped multi-segment heating mesh, in order to solve the problem in the above-mentioned background technology that the heating mesh will heat up simultaneously when powered on, making it inconvenient to control the heating area of the heating mesh.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-cost atomizing core structure based on a stepped multi-segment heating mesh, comprising an upper cover and a fixing ring, wherein an outer tube is installed on the upper cover and the fixing ring;
[0007] The inner cavity of the outer tube is provided with a stepped heating element. The heating element consists of a ring-shaped heating mesh and a power supply wire assembly. The heating element includes a first heating mesh and a second heating mesh arranged in parallel, and there are two of each of the first heating mesh and the second heating mesh.
[0008] Preferably, the power supply conductor assembly includes a main power supply line and two sets of symmetrically arranged first auxiliary power supply lines and second auxiliary power supply lines, and the outer tube sidewall is provided with three external liquid guiding holes at equal intervals.
[0009] Preferably, the top of the cover is provided with an air passage, and the lower end of the cover is provided with two coaxial annular sealing grooves, and a sealing ring is embedded in the sealing groove.
[0010] Preferably, the fixing ring is rotatably connected to a clip, and a cotton-filled rod is fixedly connected to the inner wall of the clip, and the heating element is distributed in a ring structure on the outside of the cotton-filled rod.
[0011] Preferably, the power supply wire assembly passes through the internal channel of the card and forms a clamping structure through the cooperation between the inner wall of the card and the outer wall of the cotton-wrapping rod.
[0012] Preferably, a bracket is installed inside the outer tube, and an annularly distributed inner liquid guiding holes are provided on the outer side of the bracket, and the inner liquid guiding holes and the outer liquid guiding holes are aligned. The lower end of the bracket is fixedly connected to the outer side of the top of the card.
[0013] Preferably, an oil-guiding cotton is fixedly connected inside the bracket, and the oil-guiding cotton covers the outside of the cotton-wrapping rod, and the oil-guiding cotton and the outside of the heating mesh are in close contact with each other.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This is a low-cost atomizing core structure based on a stepped multi-segment heating mesh. Through the stepped multi-segment heating mesh design, each segment of the heating mesh can be controlled independently. Users can choose to activate different numbers of heating meshes to adjust the heating area and temperature to achieve an atomization effect that suits their personal preferences.
[0016] The atomizer coil features an offset design between the outer and inner liquid guide holes, allowing users to adjust the e-liquid flow by rotating the outer tube. This design enables users to effectively control the e-liquid intake, preventing leakage caused by excessive e-liquid intake and ensuring that the amount of e-liquid is appropriate for each vaporization, resulting in a more stable atomization effect.

Detailed Implementation
[0023] 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.
[0024] Example 1: Please refer to Figure 1 - Figure 5This utility model provides the following technical solution: a low-cost atomizing core structure based on a stepped multi-segment heating mesh, including an upper cover 1 and a fixing ring 2, with an outer tube 3 installed on the upper cover 1 and the fixing ring 2; the inner cavity of the outer tube 3 is provided with a stepped heating assembly, which consists of a ring-shaped heating mesh 5 and a power supply wire assembly 6. The heating mesh 5 includes a first heating mesh 7 and a second heating mesh 8 arranged in parallel, and there are two of each of the first heating mesh 7 and the second heating mesh 8; the power supply wire assembly 6 includes a main power supply line 9, and two sets of symmetrically arranged first auxiliary power supply lines 10 and second auxiliary power supply lines 11; three external liquid guiding holes 4 are equidistantly opened on the side wall of the outer tube 3; the top of the upper cover 1 is provided with an air passage, and the lower end of the upper cover 1 is provided with two coaxial annular sealing grooves. A sealing ring is embedded in the sealing groove; a clamp 12 is rotatably connected inside the fixing ring 2, and a cotton-wrapped rod 13 is fixedly connected to the inner wall of the clamp 12, and the heating mesh 5 is distributed in a ring structure on the outside of the cotton-wrapped rod 13; the power supply wire assembly 6 passes through the internal channel of the clamp 12 and forms a clamping structure through the cooperation between the inner wall of the clamp 12 and the outer wall of the cotton-wrapped rod 13; a bracket 14 is installed inside the outer tube 3, and an annularly distributed inner liquid guiding holes 16 are provided on the outside of the bracket 14, and the inner liquid guiding holes 16 and the outer liquid guiding holes 4 are aligned; the lower end of the bracket 14 is fixedly connected to the outer top of the clamp 12; an oil-guiding cotton 15 is fixedly connected inside the bracket 14, and the oil-guiding cotton 15 covers the outside of the cotton-wrapped rod 13, and the oil-guiding cotton 15 and the outer side of the heating mesh 5 are in close contact with each other.
[0025] During the use of the device, the e-liquid will enter the interior of the outer tube 3 through the outer liquid guide hole 4 on the outside of the outer tube 3, and enter the oil guide cotton 15 through the inner liquid guide hole 16 on the outside of the bracket 14. At this time, the oil guide cotton 15 will absorb the e-liquid for temporary storage. Subsequently, the heating mesh 5 is powered by the power supply wire assembly 6, so that the heating mesh 5 generates heat, which in turn atomizes the e-liquid stored in the oil guide cotton 15. After the smoke is formed, it will move upward along the cotton rod 13 and finally be discharged through the top cover 1, forming an atomization effect.
[0026] During the power supply process, the main power supply line 9 is always energized, and the first heating grid 7 and the second heating grid 8 are fixedly connected on both sides. Because the second auxiliary power supply line 11 is connected to the first heating grid 7, when the second auxiliary power supply line 11 is energized, the main power supply line 9, the first heating grid 7 and the second auxiliary power supply line 11 will form a circuit, causing the first heating grid 7 to start heating up, thereby evaporating the e-liquid.
[0027] Since there are two of each of the first heating mesh 7 and the second heating mesh 8, and two of each of the second auxiliary power supply line 11 and the first auxiliary power supply line 10, an independent circuit control is formed. Each of the first heating mesh 7 and the second heating mesh 8 can be controlled individually by controlling its respective auxiliary power supply line, so as to realize the power supply of different numbers of heating meshes and flexibly adjust the heating area, thereby achieving a stepped heating effect. The electrical connection between the first heating mesh 7 and the second heating mesh 8 can be flexibly configured to achieve different heating modes. For example, only activating the second heating mesh 8 can achieve a low temperature mode, and vice versa, so that users can customize the atomization effect according to their personal preferences and needs.
[0028] The outer tube 3 can rotate relative to the fixing ring 2 and the top cover 1. During the rotation of the outer tube 3, the outer liquid guide hole 4 will be misaligned with the inner liquid guide hole 16 on the outside of the bracket 14, resulting in a reduction in the area of the overlapping part of the two, thereby effectively controlling the amount of e-liquid entering, so as to achieve fine adjustment of the atomization effect.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
