Oil leakage-proof atomizing core, atomizer and electronic cigarette

Abstract

This utility model discloses a leak-proof atomizing core, comprising: an outer tube, an inner tube, and a fixing base assembly. The outer tube and the inner tube are respectively connected to the top of the fixing base assembly. A first air intake channel is formed by the outer tube surrounding the inner tube. An air inlet is provided at the top of the outer tube, allowing airflow to enter the first air intake channel from the top air inlet. The air inlet, the first air intake channel, the fixing base assembly, and the inner tube are sequentially connected to form an airflow channel, constructing a complete top-intake airflow channel. The airflow then enters the fixing base assembly from the first air intake channel, carrying the atomized smoke out from the inner tube, thus completing the suction action. By sealing the bottom of the fixing base assembly, the problem of e-liquid or condensate easily flowing out from the bottom of the atomizing core when tilted or left stagnant for a long time is solved, thereby avoiding e-liquid waste and device contamination, and improving the user's experience of using electronic cigarettes.

Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and in particular to an oil-proof atomizing core, an atomizer, and an electronic cigarette. Background Technology

[0002] The atomizer coil is the core component of an e-cigarette, responsible for heating and atomizing e-liquid for the user to inhale. Traditional atomizer coils typically use a bottom air intake design, where airflow enters through the air intake hole at the bottom of the coil, flows through the heating element, and carries the atomized vapor out. Under abnormal use, such as when tilted or left stagnant for a long time, e-liquid or condensate can easily leak out from inside the atomizer coil through the bottom air intake hole, causing leakage. This not only wastes e-liquid but also contaminates the device, seriously affecting the user's e-cigarette experience. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an oil-proof atomizing core, atomizer, and electronic cigarette.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An oil-leakage-proof atomizing core includes: an outer tube, an inner tube, and a fixing base assembly. The outer tube and the inner tube are respectively connected to the top of the fixing base assembly. The outer tube surrounds the inner tube to form a first air intake channel. An air inlet is provided at the top of the outer tube. The air inlet, the first air intake channel, the fixing base assembly, and the inner tube are sequentially connected to form an airflow channel. The bottom of the fixing base assembly is sealed.

[0006] In one embodiment, the mounting bracket assembly includes a mounting base and a bottom cover. The bottom cover is disposed at the bottom of the mounting base. The mounting base has a second air intake channel, and the bottom cover has a venting groove. The air inlet, the first air intake channel, the second air intake channel, the venting groove, and the inner tube are connected in sequence.

[0007] In one embodiment, multiple second air intake channels are provided, and each second air intake channel is evenly distributed on the fixed base.

[0008] In one embodiment, the mounting bracket assembly further includes a heating wire, a first oil-guiding cotton, and an oil inlet. The heating wire is sleeved at one end near the mounting bracket, and the heating wire has a third air intake channel that is aligned with the vent groove. The first oil-guiding cotton surrounds the heating wire, and the oil inlet is located on the side wall of the mounting bracket and is aligned with the first oil-guiding cotton.

[0021] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0022] Please see Figure 1 and Figure 2 An oil leakage-proof atomizing core 10 includes: an outer tube 100, an inner tube 200, and a fixing base assembly 300. The outer tube 100 and the inner tube 200 are respectively connected to the top of the fixing base assembly 300. The outer tube 100 surrounds the inner tube 200 to form a first air intake channel 400. The top of the outer tube 100 is provided with an air inlet 110. The air inlet 110, the first air intake channel 400, the fixing base assembly 300, and the inner tube 200 are sequentially connected to form an airflow channel. The bottom of the fixing base assembly 300 is sealed.

[0023] It should be noted that the outer tube 100 surrounds the inner tube 200 to form a first air intake channel 400. An air inlet 110 is set at the top of the outer tube 100, allowing airflow to enter the first air intake channel 400 from the top air inlet 110. The air inlet 110, the first air intake channel 400, the fixing base assembly 300, and the inner tube 200 are sequentially connected to form an airflow channel, constructing a complete top-intake airflow channel. The airflow then enters the fixing base assembly 300 from the first air intake channel 400, carrying the atomized smoke out from the inner tube 200, thus completing the suction action. Furthermore, by sealing the bottom of the fixing base assembly 300, the problem of e-liquid or condensate easily flowing out from the bottom of the atomizing core 10 when tilted or left to stand still for a long time is solved, thereby avoiding e-liquid waste and equipment contamination, and improving the user's experience of using electronic cigarettes.

[0024] Please refer to it again. Figure 1 and Figure 2 In one embodiment, the fixing seat assembly 300 includes a fixing seat 310 and a bottom cover 320. By placing the bottom cover 320 at the bottom of the fixing seat 310, the bottom of the fixing seat assembly 300 is sealed. The fixing seat 310 has a second air intake channel 311, and the bottom cover 320 has a venting groove 321. The air inlet 110, the first air intake channel 400, the second air intake channel 311, the venting groove 321, and the inner tube 200 are connected in sequence, thereby optimizing the airflow channel and allowing the airflow to smoothly enter the inner tube 200 from the first air intake channel 400.

[0025] Please refer to it again. Figure 2 In one embodiment, multiple second air intake channels 311 are provided, and each second air intake channel 311 is evenly distributed on the fixed base 310. This arrangement can make the airflow distribution more uniform and improve the atomization efficiency.

[0026] Please refer to it again. Figure 1 In one embodiment, the mounting base assembly 300 further includes a heating wire 330, a first oil-guiding cotton 340, and an oil inlet 350. The heating wire 330 is sleeved on the end of the inner tube 200 near the mounting base 310. The heating wire 330 is used to heat and atomize the e-liquid into smoke. The heating wire 330 has a third air intake channel 331. The smoke atomized by the heating wire is located in the third air intake channel 331. The third air intake channel 331 is aligned with the ventilation groove 321 to facilitate airflow. The airflow is further optimized so that it can smoothly enter the third air intake channel 331 from the air vent 321, and transfer the smoke in the third air intake channel 331 to the inner tube 200. The first oil guide cotton 340 is arranged around the heating wire 330, and the oil inlet 350 is opened on the side wall of the fixing seat 310. The oil inlet 350 is aligned with the first oil guide cotton 340 so that the e-liquid can be smoothly guided from the oil inlet 350 into the heating wire 330, ensuring that the e-liquid can be heated and atomized evenly.

[0027] Please refer to it again. Figure 1 In one embodiment, the fixing seat assembly 300 further includes a second oil-guiding cotton 360, which is arranged around the first oil-guiding cotton 340. The double-layer oil-guiding cotton structure formed by the first oil-guiding cotton 340 and the second oil-guiding cotton 360 greatly enhances the oil-locking ability and further avoids the occurrence of oil leakage.

[0028] In one embodiment, the heating wire 330 is a mesh heating wire, which has a larger heating area, can provide a more uniform heating effect, and improve atomization efficiency and atomization effect.

[0029] Please refer to it again. Figure 1 and Figure 2 In one embodiment, multiple oil inlets 350 are provided, and each oil inlet 350 is evenly distributed on the side wall of the fixing base 310, so that the e-liquid enters evenly and avoids local dry burning of the heating wire 330.

[0030] Please refer to it again. Figure 1 In one embodiment, the height of the end of the inner tube 200 away from the fixed base is higher than the height of the air inlet 110, which facilitates the assembly of the inner tube 200 with other components of the electronic cigarette. At the same time, it ensures that the airflow enters the first air intake channel 400 from the air inlet 110, and avoids the airflow from being dispersed to enter from the inner tube 200 when the user inhales, thus affecting the smooth completion of the inhalation process.

[0031] An atomizer includes the aforementioned leak-proof atomizing core 10. Applying the leak-proof atomizing core 10 to the atomizer can significantly improve the leak-proof performance of the atomizer.

[0032] An electronic cigarette, including the aforementioned atomizer, has better leak-proof performance and improves user experience.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
