Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarettes, and in particular to an atomizer structure that prevents oil leakage. Background Technology
[0002] As the core component of an electronic cigarette, the atomizer functions by using a battery-powered heating element (such as a heating coil) to heat and atomize e-liquid into inhalable vapor. In existing technology, most atomizers employ a bottom-intake design, where airflow enters through a bottom air intake port on the atomizer body, flows through the coil, and carries the vapor out through the mouthpiece. However, this design has a significant drawback: because the bottom air intake port is directly connected to the coil, during transportation, storage, or tilted use, e-liquid or condensate inside the atomizer is easily affected by gravity and leaks out through the bottom air intake port, causing leakage that not only contaminates the device but also negatively impacts the user experience. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an atomizer structure that prevents oil leakage.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] An atomizer structure for preventing e-liquid leakage includes: an atomizer core assembly and an e-liquid bottle. The atomizer core assembly includes an e-liquid bottle holder, an atomizer core, a mouthpiece, and an air inlet. The atomizer core is connected to the bottom of the e-liquid bottle holder, the mouthpiece is connected to the top of the e-liquid bottle holder, and the air inlet is located at the top of the e-liquid bottle holder. The air inlet, the atomizer core, and the mouthpiece are sequentially connected to form an airflow channel. The e-liquid bottle is connected to the bottom of the e-liquid bottle holder and is used to store e-liquid.
[0006] In one embodiment, a sealing gasket is provided at the connection between the oil bottle and the oil bottle fixing seat.
[0007] In one embodiment, the oil bottle is detachably connected to the oil bottle mounting base.
[0008] In one embodiment, multiple air inlets are provided, and each air inlet is connected to the atomizing core.
[0009] In one embodiment, the oil bottle holder includes an air regulating valve, which is slidably disposed on one side of each of the air inlets, and the air regulating valve is used to control the number of air inlets in use.
[0010] In one embodiment, the oil bottle holder further includes a gas path silicone sealant, which has an air inlet channel that communicates with the air inlet hole.
[0011] In one embodiment, the airway silicone includes a sealing portion disposed at the connection between the suction nozzle and the oil bottle holder.
[0012] In one embodiment, the atomizing core assembly further includes a plurality of magnetic components disposed at the bottom of the oil bottle holder.
[0013] In one embodiment, the atomizing core assembly further includes an electrode connection portion disposed at the bottom of the oil bottle holder.
[0014] In one embodiment, a limiting part is provided at the bottom of the oil bottle, and the end of the atomizing core away from the oil bottle fixing base is connected to the limiting part.
[0015] Compared with the prior art, the present invention has at least the following advantages:
[0016] This invention's leak-proof atomizer structure places the air inlet at the top of the oil bottle holder. The air inlet, atomizing core, and mouthpiece are sequentially connected to form an airflow channel. When the user inhales, airflow enters the atomizing core from the top of the oil bottle holder, transferring the atomized vapor to the mouthpiece for the user to inhale. This top-inlet design changes the traditional bottom-inlet method, effectively preventing e-liquid or condensate from leaking out of the air inlet due to gravity during transportation, storage, or tilted use. Furthermore, since the atomizer lacks a bottom air inlet, any e-liquid or condensate leaking to the bottom of the oil bottle will be carried out by the airflow to the atomizing core during inhalation, where it will be re-heated and atomized, reducing e-liquid waste.

[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 Figures 1 to 2 An atomizer structure 10 for preventing oil leakage includes: an atomizing core assembly 100 and an oil bottle 200. The atomizing core assembly 100 includes an oil bottle holder 110, an atomizing core 120, a mouthpiece 130, and an air inlet 140. The atomizing core 120 is connected to the bottom of the oil bottle holder 110, the mouthpiece 130 is connected to the top of the oil bottle holder 110, and the air inlet 140 is located at the top of the oil bottle holder 110. The air inlet 140, the atomizing core 120, and the mouthpiece 130 are sequentially connected to form an airflow channel. The oil bottle 200 is connected to the bottom of the oil bottle holder 110 and is used to store e-liquid.
[0023] It should be noted that by connecting the atomizing coil 120 to the bottom of the e-liquid bottle holder 110, and the e-liquid bottle 200 to the bottom of the e-liquid bottle holder 110, the atomizing coil 120 is positioned inside the e-liquid bottle 200, which stores e-liquid. The atomizing coil heats and atomizes the e-liquid stored in the bottle. The air intake 140 is located at the top of the e-liquid bottle holder 110. Furthermore, by sequentially connecting the air intake 140, the atomizing coil 120, and the mouthpiece 130, an airflow channel is formed. This allows airflow to enter from the top of the e-liquid bottle holder 110 when the user inhales. The vapor is inserted into the atomizing core 120 and transferred to the mouthpiece 130, allowing the user to inhale. The top air intake method changes the traditional bottom air intake method. During transportation, storage, or tilted use, it can effectively prevent e-liquid or condensate from leaking out of the air intake 140 due to gravity. Furthermore, since the atomizer does not have a bottom air intake 140, even if e-liquid or condensate leaks to the bottom of the e-liquid bottle 200, it will be carried out to the atomizing core 120 by the airflow when the user inhales, where it will be heated and atomized again, thereby reducing e-liquid waste.
[0024] Please refer to it again. Figure 1 In one embodiment, a sealing gasket 300 is provided at the connection between the oil bottle 200 and the oil bottle fixing seat 110. The sealing gasket 300 further enhances the sealing between the oil bottle 200 and the oil bottle fixing seat 110, prevents oil leakage at the connection, and improves the reliability and service life of the product.
[0025] Please refer to it again. Figure 1 In one embodiment, the oil bottle 200 and the oil bottle fixing base 110 are detachably connected, which makes it convenient for the user to assemble the oil bottle 200 assembly with the atomizing core assembly 100, and also makes it convenient for the user to refill the e-liquid. Preferably, a threaded connection is adopted, which can make the sealing gasket 300 achieve a better compression sealing effect, and at the same time, the connection is stable and reliable.
[0026] In one embodiment, multiple air inlets 140 are provided, and each air inlet 140 is connected to the atomizing core 120. The design of multiple air inlets 140 increases the air intake, improves the atomization efficiency, and disperses the airflow, making the atomization more uniform and improving the user experience.
[0027] Please refer to it again. Figure 1 In one embodiment, the oil bottle holder 110 includes an air regulating valve 111, which is slidably disposed on one side of each air inlet 140. The air regulating valve 111 is used to control the number of air inlets 140 in use, so that the user can adjust the airflow size to meet the usage needs of different users.
[0028] Please refer to it again. Figure 1 In one embodiment, the oil bottle fixing base 110 also includes a gas passage silicone 112. The gas passage silicone 112 has an air inlet channel, which is connected to the air inlet hole 140. The gas passage silicone 112 can effectively isolate the intrusion of external moisture, dust and other harmful substances. The gas passage silicone is elastic and can effectively absorb vibration and impact during use, preventing oil leakage caused by vibration.
[0029] Please refer to it again. Figure 1 In one embodiment, the airway silicone 112 includes a sealing part 112a, which is disposed at the connection between the nozzle 130 and the oil bottle fixing seat 110, further enhancing the sealing performance of the connection between the nozzle 130 and the oil bottle fixing seat 110 and preventing smoke or oil from leaking out from the connection.
[0030] Please refer to it again. Figure 2 In one embodiment, the atomizer core assembly 100 further includes a plurality of magnetic components 150. The magnetic components 150 are disposed at the bottom of the oil bottle holder 110. The magnetic components 150 facilitate the quick docking and fixation of the atomizer with the electronic cigarette shell and other parts, thereby improving the ease of use.
[0031] Please refer to it again. Figure 2 In one embodiment, the atomizing core assembly 100 further includes an electrode connection portion 160, which is disposed at the bottom of the oil bottle holder 110. The electrode connection portion 160 provides a stable electrical connection interface, thereby improving the structural compactness of the atomizer.
[0032] Please refer to it again. Figure 1 In one embodiment, a limiting part 210 is provided at the bottom of the oil bottle 200, and the end of the atomizing core 120 away from the oil bottle fixing seat is connected to the limiting part 210. The limiting part 210 plays a role in fixing and limiting the atomizing core 120, preventing the atomizing core 120 from shifting or loosening during use, and improving the stability of the atomizer.
[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but 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.
