Description

Technical Field

[0001] This utility model relates to the field of electronic atomization device technology, and in particular to a ceramic heating element with an oil guide groove. Background Technology

[0002] In electronic cigarettes and other electronic atomization devices, the ceramic heating element is the core component for atomizing e-liquid. Its performance directly determines the amount of vapor produced, the fidelity of the flavor, and the stability of use, and is a key factor affecting the user experience.

[0003] To achieve continuous atomization, e-liquid needs to be efficiently and evenly delivered to the heating surface of the ceramic heating element. Existing technologies typically employ wicking grooves on the ceramic body or utilize the porous structure of the ceramic itself. However, these designs often face an inherent contradiction.

[0004] Specifically, if the wicking channel is designed to be wide and deep in pursuit of rapid wicking speed, while the e-liquid can be absorbed quickly, it is difficult to achieve uniform distribution across the entire heating surface. This can easily lead to localized e-liquid accumulation while other areas receive insufficient e-liquid, resulting in dry burning and severely affecting the flavor. Conversely, if a thinner and shallower wicking channel is used to improve the uniformity of e-liquid distribution, although capillary action is utilized, the slow wicking rate cannot meet the instantaneous demand for large amounts of e-liquid during continuous or high-power use, leading to reduced vapor production or even interruption of vapor production.

[0005] Therefore, this utility model proposes a ceramic heating element with an oil guide groove to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a ceramic heating element with an oil guide groove, aiming to improve the problem that the oil guiding speed and uniformity of the ceramic heating element with an oil guide groove are difficult to balance, which easily leads to insufficient oil supply or dry burning. This utility model aims to provide a ceramic heating element with an oil guide groove with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ceramic heating element with an oil guiding groove, comprising: a ceramic plate, a heating mechanism, and an oil guiding mechanism. The ceramic plate has a heating surface and an atomizing surface facing each other, and an atomizing hole is formed through the atomizing surface. The heating mechanism includes a heating wire integrally formed on the heating surface of the ceramic plate, with a positive electrode and a negative electrode extending from both ends of the heating surface.

[0008] The oil guiding mechanism is the core innovative structure of this utility model. The oil guiding mechanism is integrally formed on the heating surface of the ceramic plate. The oil guiding mechanism is provided with a protruding post, which defines a main oil groove and a secondary oil guiding groove on the heating surface. Furthermore, the groove width and groove depth of the main oil groove are both greater than the groove width and groove depth of the secondary oil guiding groove.

[0009] Preferably, the heating mechanism further includes an insulating protective sheet, which covers and is fixed to the positive electrode and the negative electrode.

[0010] Preferably, the insulating protective sheet has an annular sheet structure and is distributed around the path of the heating wire on the heating surface.

[0011] Preferably, an anti-carbon deposit coating is formed on the inner wall surface of the main oil tank and the secondary oil tank.

[0012] Preferably, the material of the anti-carbon deposition coating is a diamond-like carbon coating.

[0013] Preferably, the ceramic heating element with oil guide groove further includes a rubber sealing ring, which is sleeved and fixed to the outer peripheral sidewall of the ceramic sheet.

[0014] Preferably, the connection between the oil guiding mechanism, the heating wire, and the ceramic sheet is an integral co-fired structure.

[0015] Preferably, the protrusion is a strip-shaped protrusion extending radially or chordally along the oil guiding mechanism.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting a main oil groove and a secondary oil groove separated by protruding pillars on the heating surface of the ceramic plate, and making the size of the main oil groove larger than that of the secondary oil groove, the contradiction between the slow oil guiding speed and uneven distribution of the heating element in the prior art is solved. This achieves the technical effect of rapid oil absorption and uniform oil distribution working together, ensuring the stability and sufficiency of e-liquid supply, effectively preventing dry burning, and improving atomization efficiency.

[0017] 2. This utility model solves the problem in the prior art that carbon deposits are easily generated due to the high-temperature cracking of e-liquid, which affects the taste and shortens the service life. By forming an anti-carbon deposit coating on the inner wall surface of the main oil tank and the secondary oil tank, this invention achieves the technical effect of delaying carbon deposit formation and keeping the oil guiding channel unobstructed, thereby ensuring the purity and consistency of the atomized taste and significantly extending the service life of the heating element.

[0020] 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.

[0021] Please refer to Figures 1 to 4 This utility model provides a ceramic heating element with an oil guide groove, which aims to solve the problems in the prior art where the oil guiding efficiency and uniformity of ceramic heating elements are difficult to balance, carbon deposits are easily generated, and there is a risk of oil leakage.

[0022] like Figure 1 and Figure 3As shown, the ceramic heating element with oil guide groove includes a ceramic plate 1, which has a heating surface and an atomizing surface facing each other. An atomizing hole 2 is formed through the atomizing surface of the ceramic plate 1. A heating mechanism 4 is disposed on the heating surface of the ceramic plate 1. The heating mechanism 4 includes a heating wire 404, which is integrally formed on the heating surface of the ceramic plate 1. The two ends of the heating wire 404 extend from the heating surface to form a positive electrode 401 and a negative electrode 402. The ceramic heating element with oil guide groove also includes an oil guiding mechanism 3, which is integrally formed on the heating surface of the ceramic plate 1. A protrusion 301 is provided on the oil guiding mechanism 3. The protrusion 301 defines a main oil guide groove 302 and a secondary oil guide groove 303 on the heating surface of the ceramic plate 1. The groove width and groove depth of the main oil guide groove 302 are both greater than the groove width and groove depth of the secondary oil guide groove 303. In this embodiment, the protrusion 301 is a strip-shaped protrusion extending radially or chordally along the oil guiding mechanism 3. Through the physical separation of the protrusion 301, the distribution area of ​​e-liquid on the heating surface is divided into two channels with different geometric shapes, namely the main oil channel 302 and the secondary oil guiding channel 303. The main oil channel 302 has a larger groove width and groove depth, forming a larger accommodating space, which can quickly receive and store e-liquid. The secondary oil guiding channel 303 has a smaller groove width and groove depth, which uses capillary action to evenly transport the e-liquid conducted from the main oil channel 302 to a wider area of ​​the heating surface. Preferably, the oil guiding mechanism 3, the heating wire 404 and the ceramic plate 1 are integrally co-fired and molded. This structure allows for seamless connection between the components, ensuring excellent heat conduction efficiency and structural stability.

[0023] The heating mechanism 4 also includes an insulating protective sheet 403, which is a ring-shaped sheet structure. The insulating protective sheet 403 covers and is fixed on the positive electrode 401 and the negative electrode 402, and is distributed around the path of the heating wire 404 on the heating surface of the ceramic sheet 1. This covering and isolation structure can effectively prevent the positive electrode 401 and the negative electrode 402 from short-circuiting due to accidental contact or intrusion of conductive medium, and ensure the electrical safety of the ceramic heating element with oil guide groove when it is powered on. In addition, to address the issue of carbon buildup in e-liquid at high temperatures, which affects wicking efficiency and atomization flavor, an anti-carbon buildup coating 304 is formed on the inner wall surfaces of the main wicking channel 302 and the secondary wicking channel 303. The material of the anti-carbon buildup coating 304 is preferably a diamond-like carbon coating. This coating has a smooth surface and is not easily wetted by e-liquid residues, which can significantly reduce the adhesion and accumulation of carbon deposits in the wicking channel, thereby maintaining the smoothness of the wicking path for a long time and stabilizing the supply of e-liquid and the atomization effect.

[0024] As a preferred embodiment, to reliably prevent e-liquid from leaking from the wicking mechanism 3 to the outside, please refer to... Figure 1The ceramic heating element with oil guide groove also includes a rubber sealing ring 305. The rubber sealing ring 305 is an elastic ring structure and is sleeved and fixed on the outer peripheral side wall of the ceramic plate 1, forming a seal by filling the assembly gap between the ceramic plate 1 and the external components.

[0025] In a preferred embodiment, the protrusion 301 is specifically manifested as a strip-shaped protrusion extending radially or chordally along the oil guiding mechanism 3, which is beneficial for guiding the directional flow of e-liquid.

[0026] Working principle: When the external power supply is connected to the positive terminal 401 and the negative terminal 402, the current flows through the heating wire 404, which quickly generates heat. Since the heating wire 404 is integrally formed on the heating surface of the ceramic plate 1, the heat is efficiently transferred to the entire ceramic plate 1. At the same time, the external e-liquid is absorbed by the oil guiding mechanism 3. The main oil groove 302, which has a large groove width and groove depth, quickly absorbs and stores e-liquid due to its structural advantages, providing sufficient raw materials for the subsequent atomization process. The e-liquid stored in the main oil tank 302 is guided by the secondary oil guide tank 303, which has a smaller opening width and deeper body, under capillary action, and is quickly and evenly distributed to the entire heating surface. This structure, in which the main and secondary oil guide tanks work together separated by the protruding post 301, ensures that the heating surface can obtain a continuous and sufficient supply of e-liquid. When the heating surface soaked in e-liquid reaches the atomization temperature, the e-liquid is instantly heated and atomized into smoke. The smoke is finally output to the outside through the atomization hole 2 on the atomization surface of the ceramic plate 1. Throughout the entire operation, the anti-carbon deposit coating 304 formed on the inner wall surface of the main oil tank 302 and the secondary oil guide tank 303 can effectively inhibit carbide deposition, thereby keeping the oil guide path unobstructed. The rubber sealing ring 305, which is sleeved and fixed to the outer peripheral side wall of the ceramic plate 1, effectively prevents the e-liquid from leaking to the outside from the edge of the oil guide mechanism 3. The insulating protective sheet 403 covering the positive electrode 401 and the negative electrode 402 continuously provides electrical insulation protection to prevent short circuits and ensure the long-term stable and safe operation of the entire device.
