[0037] 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.

[0038] 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.

[0039] First, the advantages of using ceramics in atomizers are as follows:

[0040] 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.

[0041] 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.

[0042] Fine atomized particles:

[0043] 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.

[0044] 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.

[0045] Example 1: The specific structure of this utility model is as follows:

[0046] Please refer to the appendix. Figure 1-7 The present invention provides an electronic cigarette atomizer with a 3D ceramic cup structure, including a metal shell 4, a heating element 23, a base 5 for connecting to a battery, and a terminal group.

[0047] The metal outer shell 4 has a through cavity extending through both ends, and a retaining ring 41 is provided in the through cavity to form a first mounting cavity and a second mounting cavity; the metal outer shell 4 is a stainless steel shell.

[0048] The heating element 23 has a ceramic cup 2 and a heating element 3 integrally formed with the ceramic cup 2. The ceramic cup 2 has a cylindrical structure and is installed in the first mounting cavity and defined by a perforated cover 1. The interior of the ceramic cup 2 is divided into two open cavities by a partition. The first cavity and the cover 1 form an atomizing chamber. The heating element 3 has two heating element wires leading out from the second cavity. The second cavity also encapsulates a thermostat, which has two temperature control wires leading out. The negative wires of the two heating element wires and the negative wires of the two temperature control wires share the same negative terminal, and the other two wires are positive wires. The cover 1 is a stainless steel cover with a knurled structure on its outer circumference.

[0049] The base 5 is used to connect with the battery section. The base 5 is fixed to the second mounting cavity. Its outer end has an outwardly protruding connecting post 51. The connecting post 51 has a through hole communicating with the second cavity. The negative electrode line is electrically connected to the base 5. The base 5 is a metal base.

[0050] The terminal assembly is located in the through hole. The conductive structure of the terminal assembly is a linear conductive direction to a circular electrical contact structure. The inner and outer contacts of this circular electrical contact structure are both positive contacts. Two positive contacts and 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. The connecting post 51 is provided with external threads and is threadedly connected to the battery section.

[0051] The terminal group includes:

[0052] An insulating member 6, whose outer profile is adapted to the through hole, is fixed to the through hole. The insulating member 6 is a food-grade high-temperature resistant silicone part. Its first end has a guide hole for two positive electrode wires to enter, and its second end has a circular post 61 that separates the two positive electrode wires. The inside of the circular post 61 is a cylindrical cavity, and its outside is a circular cavity. The two positive electrode wires enter the cylindrical cavity and the circular cavity respectively. The insulating member 6 is a silicone insulating member. Correspondingly, the through hole includes an oblong hole 52 and a cylindrical cavity 53.

[0053] 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.

[0054] 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.

[0055] The heating element 3 is printed on the ceramic cup 2, and includes:

[0056] The cylindrical grid section formed by printing is formed by sequentially connecting several vertically distributed circular resistance lines;

[0057] 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.

[0058] Example 2:

[0059] I. The following is the overall assembly of the atomizer of this utility model:

[0060] The atomizer has a stainless steel outer shell 4, which forms a first mounting cavity and a second mounting cavity. The material of the outer shell 4 ensures the strength and durability of the atomizer.

[0061] A cylindrical ceramic cup 2 is installed into the first mounting cavity. The interior of the ceramic cup 2 is divided into two open cavities by a partition. Next, a stainless steel cap 1 with a knurled outer surface is used to secure the ceramic cup 2 within the first mounting cavity, forming an atomization chamber between the first cavity of the ceramic cup 2 and the cap 1. The knurled structure facilitates the installation and removal of the cap 1.

[0062] A thermostat is encapsulated in the second cavity of the ceramic cup 2, and the heating element 3 is integrally formed with the ceramic cup 2. Two heating element wires are led out from the second cavity of the heating element 3, and two temperature control wires are led out from the thermostat. The negative wires of the two heating element wires and the negative wires of the two temperature control wires are set to share the same negative terminal, and the other two are positive wires.

[0063] The metal base 5 is fixed to the second mounting cavity. The protruding connecting post 51 at the outer end of the base 5 has external threads, and the connecting post 51 has a through hole communicating with the second cavity. The negative electrode line with a common negative electrode is electrically connected to the base 5, so that current can be transmitted through the base 5.

[0064] Install the terminal block into the through hole of the connecting post 51. Specifically install the insulating component 6, whose outer profile matches the through hole, and first fix the insulating component 6 to the through hole. The guide hole at the first end of the insulating component 6 allows two positive wires to enter, and the annular post 61 at the second end separates the two positive wires. The two positive wires enter the cylindrical cavity inside the annular post 61 and the annular cavity outside the annular post 61, respectively.

[0065] The first electrode 7 is fixed in the annular cavity, 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 in the cylindrical cavity, electrically connected to the second positive wire entering the cylindrical cavity. The second electrode 8 is a solid cylindrical electrode. At this point, the terminal assembly is complete, forming an annular electrical contact structure that transitions from linear conductivity to a circular contact structure. The two positive contacts (i.e., the first electrode 7 and the second electrode 8) and the connecting post 51 form a three-point electrical contact structure.

[0066] II. Specific structure and installation of heating element 3:

[0067] The cylindrical grid part of the heating element 3 is made by hollowing out multiple wire holes in a cylindrical metal wall, thereby forming a number of vertically distributed circular resistance wire structures in the cylindrical metal wall.

[0068] The two ends of the curved resistance wire are connected to the two endpoints of the diameter of the cylindrical mesh section, and two heating element wires are led out from the two connection points of the curved resistance wire and the cylindrical mesh section.

[0069] The pre-made heating element 3 is integrally formed with the ceramic cup 2, so that the cylindrical mesh part and the curved resistance wire are embedded in the interior of the ceramic cup 2, ensuring that the heating element 3 can work stably and is tightly integrated with the ceramic cup 2.

[0070] III. Connection with the battery section and its working principle:

[0071] When the electronic cigarette atomizer needs to be used, the atomizer is connected to the battery section via the external thread of the connecting post 51 to connect the circuit.

[0072] The current in the battery is transmitted through two positive contacts. Due to the special structure of the terminal group, the two positive contacts (first electrode 7 and second electrode 8) are electrically connected to two positive wires respectively, and the negative wire transmits current through the base 5, forming a complete circuit loop.

[0073] When current flows through the heating element 3, the cylindrical mesh section and the curved resistance wire heat up, heating the e-liquid in the first compartment of the ceramic cup 2. After the e-liquid is heated and atomized, it enters the user's mouth through the atomization chamber, realizing the function of electronic cigarette atomization. At the same time, the temperature controller monitors the temperature in real time. When the temperature is abnormal, it feeds back information through the temperature control wire and adjusts the heating of the heating element 3 to ensure the safety and stability of the atomization process.

[0074] In summary, the one-piece molded ceramic cup and heating element of this invention provide a larger heating area and a more uniform temperature distribution, effectively improving atomization efficiency and taste stability, and reducing scorching.

[0075] The heating element wire and the temperature control wire of this invention share a common negative terminal, which simplifies the circuit structure, reduces connection points, lowers contact resistance and the risk of failure, and improves reliability.

[0076] The terminal assembly of this utility model adopts an inner and outer electrode design separated by a ring column, realizing the conversion from linear conduction to ring-type electrical contact, increasing the contact area, and improving connection stability and durability; the three-point electrical contact structure further ensures the reliability of circuit conduction while reducing the atomizer volume.

[0077] This utility model has a built-in thermostat to monitor the temperature in real time, preventing dry burning and overheating, extending service life, and improving safety during use.

[0078] The stainless steel shell and cover of this utility model provide good mechanical strength and corrosion resistance; the knurled structure design enhances the grip and facilitates operation; the through-hole design of the oval hole and cylindrical cavity optimizes the wire layout and fixing method.

[0079] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
