Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and more specifically, to a high-temperature resistant ceramic core rod for electronic cigarettes. Background Technology

[0002] As an innovative tobacco alternative, e-cigarettes are electronic products that use batteries to atomize e-liquid. Their core structure consists of a main unit, an atomizer, and e-liquid. The working principle is that after a sensor detects the inhalation action, the heating coil converts the nicotine, propylene glycol, glycerin, and other components in the e-liquid into an aerosol for inhalation. The high-temperature resistant ceramic core rod of e-cigarettes is the core component of the e-cigarette atomization system. The ceramic material can withstand long-term high-temperature environments without deformation.

[0003] The existing technology still has the following drawbacks: E-liquid can easily leak to the connection between the coil and the atomizing chamber, causing poor contact. Moreover, when the e-cigarette is subjected to a certain degree of vibration or shaking, poor contact can also easily occur. Poor contact will cause unstable current transmission, and the metal heating wire will not be able to obtain a continuous and stable power supply. This will cause the temperature of the metal heating wire to fluctuate, making it impossible to stably vaporize the e-liquid, which in turn affects the amount and quality of aerosol generation.

[0004] Therefore, a high-temperature resistant ceramic core rod for electronic cigarettes is proposed. Utility Model Content

[0005] The purpose of this invention is to address the existing problems of e-liquid easily leaking to the connection between the coil and the atomizing chamber, leading to poor contact. Furthermore, poor contact is also prone to occur when the e-cigarette is subjected to vibration or shaking. Poor contact results in unstable current transmission, preventing the metal heating wire from receiving a continuous and stable power supply. This causes the temperature of the metal heating wire to fluctuate, making it difficult to stably vaporize the e-liquid, thus affecting the amount and quality of aerosol generation. The invention provides a high-temperature resistant ceramic coil for e-cigarettes to solve these problems.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a high-temperature resistant ceramic core rod for electronic cigarettes, comprising a core rod, wherein the bottom of the core rod is provided with an installation component for mounting the core rod on an electronic cigarette atomization chamber; The mounting assembly includes a connecting plate fixedly mounted to the bottom of the mandrel, a sleeve fixedly connected to the bottom of the connecting plate, a spring fixedly mounted on the inner wall of the sleeve, a conductive pin fixedly provided at the other end of the spring, a metal heating wire embedded inside the mandrel, and a sealing ring fixedly provided at the bottom of the connecting plate.

[0007] As a preferred technical solution of this utility model, the conductive pin slides inside the sleeve, and the two ends of the metal heating wire are fixedly connected to the sleeve. The metal heating wire is made of nickel-chromium alloy.

[0008] As a preferred technical solution of this utility model, the metal heating wire is located on one side of the sealing ring, and the sealing ring is made of polytetrafluoroethylene.

[0009] As a preferred technical solution of this utility model, a limiting flange is fixedly provided on the outer side wall of the mandrel, and the cross-section of the limiting flange is rectangular.

[0010] As a preferred technical solution of this utility model, the core rod is a hollow tubular structure, and the surface of the core rod is provided with through holes.

[0011] As a preferred technical solution of this utility model, an anti-slip groove is fixedly provided on the top of the limiting flange, and the anti-slip groove is located on one side of the mandrel.

[0012] As a preferred technical solution of this utility model, the core rod is made of alumina and zirconium oxide composite ceramic, and the surface of the sleeve is coated with a corrosion-resistant conductive layer, the material of which is platinum.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The installation components prevent e-liquid from seeping into the connection between the coil and the atomizing chamber, avoiding poor contact caused by e-liquid leakage. This ensures that the current can be transmitted stably and efficiently to the metal heating wire, guaranteeing the continuous and stable operation of the heating wire and ensuring the stability of the amount and quality of aerosol generation. 2. Through the designed conductive pins, a continuous and stable current is provided to the metal heating wire. During the use of the electronic cigarette, even if there is some vibration or shaking, the elasticity of the spring can ensure that the conductive pins always maintain good contact with the battery system, thereby providing a continuous and stable current to the metal heating wire and ensuring the normal operation of the electronic cigarette.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0017] Example: Figure 1 and Figure 5 As shown, this embodiment proposes a high-temperature resistant ceramic core rod for electronic cigarettes, including a core rod 1, and an installation component 2 for mounting the core rod 1 on the atomizing chamber of the electronic cigarette is provided at the bottom of the core rod 1. like Figure 5 As shown, the mounting assembly 2 includes a connecting plate 201 fixedly mounted to the bottom of the core rod 1. A sleeve 202 is fixedly connected to the bottom of the connecting plate 201. A spring 205 is fixedly mounted on the inner wall of the sleeve 202. A conductive pin 206 is fixedly provided at the other end of the spring 205. A metal heating wire 203 is embedded inside the core rod 1. A sealing ring 204 is fixedly provided at the bottom of the connecting plate 201. When in use, when the coil 1 is installed in the e-cigarette, the conductive pin 206 is pushed outward by the spring 205, ensuring that the conductive pin 206 is tightly connected to the battery system inside the e-cigarette, preventing circuit interruption due to poor contact. Current flows from the battery through the conductive pin 206, is conducted through the spring 205 and the sleeve 202 to the connecting plate 201, and finally to the metal heating wire 203. After receiving electrical energy, the metal heating wire 203 heats up rapidly to a temperature sufficient to vaporize the e-liquid, instantly vaporizing it into an aerosol that can be inhaled. The sleeve 202 is precisely connected to the circuit system inside the e-cigarette, ensuring that the current can be stably and efficiently transmitted to the metal heating wire 203, ensuring the continuous and stable operation of the heating wire. After the coil 1 is installed in the atomizing chamber, the sealing ring 204 prevents short circuits and other malfunctions in the internal circuit of the e-cigarette caused by oil leakage.

[0018] like Figure 5As shown, the conductive pins 206 slide within the sleeve 202, and the two ends of the metal heating wire 203 are fixedly connected to the sleeve 202. The metal heating wire 203 is made of nickel-chromium alloy. During the use of the electronic cigarette, even with some vibration or shaking, the elasticity of the spring 205 ensures that the conductive pins 206 always maintain good contact with the battery system, thereby providing a continuous and stable current to the metal heating wire 203 and ensuring the normal operation of the electronic cigarette. Nickel-chromium alloy has a high resistivity and, compared to other common metal materials, can generate more heat, thus enabling the nickel-chromium alloy metal heating wire 203 to reach the temperature required for vaporization of the e-liquid more quickly, improving the atomization efficiency.

[0019] like Figure 5 As shown, the metal heating wire 203 is located on one side of the sealing ring 204, which is made of polytetrafluoroethylene. The silicone sealing ring 204 effectively prevents e-liquid leakage, ensuring the cleanliness and normal operation of the e-cigarette's interior. This avoids problems such as short circuits and component corrosion caused by e-liquid leakage, thus improving the reliability and lifespan of the e-cigarette.

[0020] like Figure 1 As shown, a limiting flange 3 is fixedly provided on the outer wall of the coil 1, and the cross-section of the limiting flange 3 is rectangular. During the assembly and use of the electronic cigarette, the coil 1 needs to be precisely installed in a specific position inside the atomizing chamber. When the limiting flange 3 reaches the appropriate position, it will prevent the coil 1 from moving further in, thereby ensuring that the coil 1 is always in the optimal working position.

[0021] like Figure 2 As shown, the core rod 1 is a hollow tubular structure with through holes 4 on its surface. The atomization chamber of the electronic cigarette stores e-liquid. When the electronic cigarette is in standby or ready-to-work state, due to the presence of through holes 4 on the surface of the core rod 1, the e-liquid will be adsorbed onto the inner wall of the through holes 4 based on the principle of capillary action, ensuring that the metal heating wire 203 always has enough e-liquid for vaporization, thereby ensuring that the electronic cigarette can continuously produce a stable aerosol.

[0022] like Figure 3 As shown, the top of the limiting flange 3 is fixedly provided with an anti-slip groove 5, which is located on one side of the coil 1. When the user screws the coil 1 into the atomizing chamber, the anti-slip groove 5 allows the user to operate more stably when assembling the coil 1, reducing installation errors caused by finger slippage.

[0023] like Figure 4As shown, the core rod 1 is made of alumina and zirconium oxide composite ceramic, and the surface of the sleeve 202 is coated with a corrosion-resistant conductive layer made of platinum. In use, using alumina and zirconium oxide composite ceramic for the core rod 1 significantly improves its mechanical strength and thermal shock resistance. The corrosion-resistant conductive layer on the surface of the sleeve 202 greatly reduces the risk of equipment failure due to poor electrode contact.

[0024] Working Principle: This utility model provides a high-temperature resistant ceramic core rod for electronic cigarettes. During use: When the core rod 1 is installed in the electronic cigarette, the conductive pin 206 is pushed outward under the action of the spring 205, ensuring that the conductive pin 206 is tightly connected to the battery system inside the electronic cigarette, preventing circuit interruption due to poor contact. Current flows from the battery through the conductive pin 206, is conducted through the spring 205 and the sleeve 202 to the connecting plate 201, and finally to the metal heating wire 203. After receiving electrical energy, the metal heating wire 203 heats up rapidly to a temperature sufficient to vaporize the e-liquid, instantly vaporizing it into an aerosol that can be inhaled. The silicone sealing ring 204 effectively prevents e-liquid leakage, ensuring the cleanliness and normal operation of the electronic cigarette, avoiding problems such as short circuits and component corrosion caused by e-liquid leakage, and improving the reliability and service life of the electronic cigarette.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
