[0002] In the field of e-cigarette technology, the atomizer, as a key component that transforms e-liquid into an inhalable aerosol, significantly impacts the user experience and safety of e-cigarettes. Traditional e-cigarette atomizers suffer from imprecise temperature control when heating and atomizing e-liquid. This not only leads to incomplete atomization of the e-liquid, affecting the taste and concentration of the vapor, but may also cause localized overheating, resulting in the decomposition of e-liquid components and the generation of harmful substances that endanger the user's health.

[0003] Existing electronic cigarette atomizers have many shortcomings during use, such as inaccurate temperature control leading to insufficient atomization of e-liquid, poor taste reproduction, short service life, inconvenient cleaning, and easy generation of odors.

[0005] Therefore, it is of great significance to develop an electronic cigarette atomizer with precise temperature control, efficient atomization effect and optimized structure. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] First, the advantages of using ceramics in atomizers are as follows: High melting point characteristics: Ceramics (such as alumina and zirconium oxide) have extremely high melting points (alumina melting point is about 2054℃, zirconium oxide melting point is about 2715℃), which can withstand the high temperature generated during atomization (usually 200-300℃), and are not easily deformed or melted, ensuring structural stability for long-term use.

[0033] Thermal shock resistance: Some ceramic materials (such as cordierite) have a low coefficient of expansion, which can quickly adapt to sudden temperature changes, reduce the risk of cracking caused by frequent heating, and extend the service life of the atomizer.

[0034] Fine atomized particles: At high temperatures, the micropores on the ceramic surface allow the e-liquid to fully vaporize, forming aerosol particles with smaller diameters (approximately 0.1-1 micrometers), which improves the fineness of the vapor and the purity of the flavor, while reducing the generation of large condensate particles.

[0035] Ceramic also has the advantages of corrosion resistance, no risk of metal leaching, smooth surface that is not easy to accumulate dirt, high reusability, compatibility with a variety of e-liquid types, and reproduction of the real taste of e-liquid.

[0036] Example 1: The specific structure of this utility model is as follows: Please refer to the appendix. Figure 1-10 An atomizer that precisely heats and vaporizes e-liquid using a 3D ceramic cup, comprising: The ceramic shell 1 has a through cavity that extends through both ends. A stepped step 11 is provided in the through cavity. The ceramic shell 1 has a cylindrical structure with a chamfered inner side of the opening at the thick end. The heating element 23 has a ceramic inner shell 2 and a heating wire 3 integrally formed with the ceramic inner shell 2. The first end of the ceramic inner shell 2 is tightly fitted with a first stepped surface to form a sealed structure. Its interior is divided into two open cavities by a partition. The first cavity 21 and the first opening end of the through cavity form an atomization chamber. The heating wire 3 has two heating wire leads extending from the second cavity 22. The second cavity 22 also encapsulates a thermostat, which has two temperature control wires extending from it. The negative wires of the two heating wires and the negative wires of the two temperature control wires are shared, and the other two wires are positive wires. The ceramic inner shell 2 has a cylindrical structure. The second cavity 22 also has a thermostat. The thermostat detects the temperature of the atomization chamber in real time and generates a signal to be transmitted to the MCU on the electronic cigarette circuit board. The MCU controls the input current of the heating wire 3 according to the settings, thereby controlling the heating temperature of the heating wire 3. A conductive ring 4 is disposed in the cavity and defines the inner shell 2, and has a through hole, the negative electrode line being electrically connected to the conductive ring 4; The base 5 is used to connect to the battery section. The base 5 is sealed to the second opening end of the cavity and defines the conductive ring 4. The outer end of the base 5 has an outwardly protruding connecting post 51. The interior of the connecting post 51 is provided with a through hole communicating with the through hole. The base 5 and the conductive ring 4 are electrically abutted. The terminal group installed in the through hole has a conductive structure consisting of a linear conductive direction to a circular electrical contact structure. The inner and outer contacts of the circular electrical contact structure are both positive contacts. The two positive contacts and the two positive wires are electrically connected one-to-one. The two positive contacts and the connecting post 51 form a three-point electrical contact structure.

[0037] The terminal group includes: An insulating component 6, whose outer profile is adapted to the through hole, is fixed to the through hole. Its first end has a guide hole for two positive wires to enter, and its second end has a circular post 61 that separates the two positive wires. The inside of the circular post 61 is a cylindrical cavity, and its outside is a circular cavity. The two positive wires enter the cylindrical cavity and the circular cavity respectively. The insulating component 6 is a food-grade high-temperature resistant silicone component.

[0038] The first electrode 7 is fixed to the annular cavity and electrically connected to the first positive wire entering the annular cavity. The outer end of the first electrode 7 is an annular electrode. The second electrode 8 is fixed to the cylindrical cavity and electrically connected to the second positive electrode wire entering the cylindrical cavity. The second electrode is a solid cylindrical electrode.

[0039] The heating wire 3 is printed on the ceramic inner shell 2, and includes: The cylindrical grid section formed by printing is formed by sequentially connecting several vertically distributed circular resistance lines; The curved resistance wire is printed, and its two ends are respectively connected to the two endpoints of the diameter of the cylindrical mesh. Two heating wires are led out from the two connection points between the curved resistance wire and the cylindrical mesh.

[0040] The cylindrical mesh section and the curved resistance wire are disposed in the ceramic inner shell 2. When they are heated, they conduct heat to the ceramic inner shell 2. The tobacco paste is placed in the first cavity 21 of the ceramic inner shell 2 and is heated and atomized.

[0041] The through hole includes an oblong hole 52 and a cylindrical cavity 53 that are adjacent to the through hole; Example 2:

[0042] Within the cavity of the ceramic outer shell 1, the stepped step 11 provides stable support and a sealing surface for the ceramic inner shell 2. The first end of the ceramic inner shell 2 is tightly fitted with the first stepped surface, forming a sealed structure to prevent e-liquid leakage. The first partition 21 serves as an atomization chamber, working in conjunction with the first opening of the cavity to ensure that the e-liquid is fully atomized and inhaled by the user after heating. The second partition 22 is used to lead out the heating wire, ensuring the stability of the circuit connection.

[0043] The cylindrical mesh portion of the heating wire 3 and the curved resistance wire are embedded inside the ceramic inner shell 2. This design not only enables precise temperature control but also effectively protects the heating structure and extends its service life. When current passes through the curved resistance wire and the cylindrical mesh portion, the generated heat is evenly transferred to the surface of the ceramic inner shell 2, causing the tobacco paste to atomize at a suitable temperature.

[0044] The conductive ring 4 is installed in the cavity, which limits the ceramic inner shell 2 and ensures its positional stability. The base 5 is sealed to the second opening of the cavity and connected to the battery section via external threads, achieving a secure connection between the atomizer and the battery. The through hole inside the connecting post 51 provides installation space for the terminal group, and the design of the oblong hole 52 and the post cavity 53 effectively separates the two positive wires.

[0045] The insulating component 6 of the terminal group is made of ceramic, which has good insulation and high-temperature resistance. The annular post 61 leads the two positive electrode wires into the cylindrical cavity and the annular cavity respectively, and then achieves electrical connection with the battery section through the first electrode 7 and the second electrode 8. This design, which changes from linear conductivity to annular electrical contact structure, improves conductivity efficiency and connection stability.

[0046] The conductive ring 4 and the base 5 abut to form an electrical contact structure. The negative wire of the heating wire 3 and the negative wire of the temperature controller are both connected to the conductive ring 4, realizing the conversion of a four-wire circuit to a three-wire circuit. This design can reduce the size of the atomizer.

[0047] During use, the current supplied by the battery is transmitted to the heating wire 3 through the terminal group. The heating wire 3 generates heat, which atomizes the e-liquid in the atomizing chamber. The user inhales, allowing the vapor to enter the mouth through the first opening of the chamber, thus achieving a sense of satisfaction.

[0048] Through the above-described structural design, this invention effectively solves the problems existing in current electronic cigarette atomizers, providing users with a high-quality atomizer that offers good taste, long service life, easy cleaning, and precise temperature control.

[0049] In summary, the differences between this atomizer and other atomizers on the market are as follows: This atomizer uses a thermostat to regulate temperature; it offers a better flavor; the heating wire has a longer lifespan; the atomized vapor has a better flavor reproduction effect; and the atomizer has a simple structure, is flexible and convenient to use, and is highly practical.

[0050] The connection end of the atomizer of this utility model adopts a three-point electrical contact structure, which ensures stable contact and reduces the size of the atomizer.

[0051] This utility model atomizer can fully atomize tobacco paste, resulting in good atomization effect; the vapor produced after atomization has a good taste and no odor; the ceramic material is smooth and easy to clean.
