Description

Technical Field

[0001] This disclosure relates to the field of electric heating atomizer technology, and more particularly to a left and right oil tank type atomizer. Background Technology

[0002] E-cigarettes are atomizers containing an atomizing core filled with e-liquid. The core is electrically heated, atomizing the e-liquid into vapor aerosol particles. Inhaling e-cigarettes can alleviate nicotine cravings to some extent, serving as a substitute for traditional tobacco. Existing e-cigarette atomizers fall into two main categories: integrated e-cigarettes and pod-based e-cigarettes. Integrated e-cigarettes are non-removable and typically use an integrated e-liquid reservoir with through-holes for installing the atomizing core. Integrated e-cigarettes are popular due to their large e-liquid capacity and long battery life. Pod-based e-cigarettes consist of an e-liquid cartridge and a main unit containing a battery and control board. The cartridge is plugged into the main unit for electrical connection. Pod-based e-cigarettes are favored by consumers because of their replaceable cartridges, smaller e-liquid capacity (which helps maintain e-liquid freshness), and the ability to flexibly switch between different flavors. In both of the aforementioned types of e-cigarette atomizers, the atomizer core is immersed in a large-capacity integrated e-liquid reservoir, or the cartridge has a visible e-liquid layer, causing the atomizer core to leak out to some extent. Therefore, this invention proposes a novel e-cigarette atomizer structure that helps maintain a large e-liquid capacity while preventing e-liquid leakage from the atomizer core. Utility Model Content

[0003] The technical solution of this utility model is a left-right oil tank type atomizer, including a shell, a battery cell, a control board, and an atomizing core disposed within the shell. An inner shell is provided inside the outer shell, with an opening at its lower end. The inner shell includes a left chamber and a right chamber, which share a common intermediate sidewall. The atomizing core is installed in the left chamber, and the right chamber is an oil storage tank. A lanyard hole is provided on the intermediate sidewall near the opening, penetrating both the left and right chambers. The atomizing core is connected to a lanyard, with the other end of the lanyard passing through the lanyard hole to the right chamber. The end of the lanyard connecting to the atomizing core is higher than the lanyard hole. Oil seals are provided at the lower openings of the left and right chambers, and an air inlet hole communicating with the atomizing core is provided corresponding to the oil seal of the left chamber. An air outlet hole is provided at the upper end of the left chamber, and a mouthpiece is provided at the upper end of the shell above the left chamber, communicating with the air outlet hole.

[0004] Furthermore, the atomizing core includes a metal cover with a notch on the side wall. A heating wire element is disposed inside the metal cover, and the heating wire element is wrapped with oil-guiding cotton. The oil-guiding cotton is connected to the oil-guiding rope, and the oil-guiding rope is led out from the notch.

[0005] Furthermore, the oil-guiding rope is a rope-like component made of organic cotton or polymer integrated cotton.

[0006] Furthermore, the lower end of the metal cover is connected to a food-grade, high-temperature resistant elevating straight tube. An oil-retaining cotton is fitted on the outer wall of the metal cover and the elevating straight tube. The oil-retaining cotton is provided with holes for the oil guide rope to pass through at the notch of the metal cover.

[0007] Furthermore, a through-hole silicone component is provided at the rope-threading hole. The outer wall of the through-hole silicone component is provided with a concave ring. The concave ring is locked into the opening of the rope-threading hole, and the oil-guiding rope passes through the through-hole silicone component.

[0008] Furthermore, the oil seal component includes a first silicone component with an opening at the lower end of the left compartment and a second silicone component with an opening at the lower end of the right compartment. The first silicone component has an insertion through hole for inserting into the lower end of the heightening straight tube. A rubber cap is attached to the bottom of the first silicone component. The rubber cap has a mating through hole for mating with the insertion through hole. A first oil-absorbing cotton block is provided at the bottom of the rubber cap.

[0009] Furthermore, a cell fixing bracket is provided below the oil seal of the inner shell, and a bottom cover is provided below the cell fixing bracket. The bottom cover is snapped into the lower end of the outer shell. The upper end of the cell fixing bracket is snapped into the lower opening of the inner shell. An air inlet is provided on the outer side wall of the first oil-absorbing cotton block. The middle part of the cell fixing bracket is a groove for installing the cell.

[0010] Furthermore, a snap-fit ​​position for snapping the control board is provided at the upper left side of the left compartment. The control board is installed vertically. A mounting slot is provided above the snap-fit ​​position. An upper silicone piece is embedded in the mounting slot and the air outlet at the upper end of the left compartment. The upper silicone piece has a concave cavity and a through hole that connects to the lower end of the suction nozzle. An airflow sensor is embedded in the concave cavity. The airflow sensor is electrically connected to the control board. The inner wall of the suction nozzle has a sensor activation air passage that communicates with the concave cavity. A second oil-absorbing cotton block is provided between the bottom of the upper silicone piece and the air outlet.

[0011] Furthermore, an oil inlet is provided on the top of the right compartment, and an oil plug is provided at the oil inlet. The inner shell is integrally injection molded from food-grade transparent plastic material, and the outer shell is provided with a viewing window on the side wall corresponding to the right compartment.

[0012] Furthermore, an air inlet is provided at the bottom of the bottom cover, and an air regulating valve is provided between the bottom of the battery cell fixing bracket and the bottom cover, with the air regulating valve correspondingly installed at the air inlet.

[0013] The beneficial effects of this invention are as follows: The electronic cigarette atomizer designed in this scheme is mainly an optimization and improvement of the existing integrated electronic cigarette. It features a left and right chamber side-by-side sharing a central sidewall. The left chamber is the atomization chamber, while the right chamber is the main oil storage chamber. The atomizer core passes through the right chamber via a wicking cord, which absorbs and guides the e-liquid to the atomizer core for atomization. During this absorption and guidance process, some e-liquid is guided to the atomizer core, while some is absorbed by the oil storage cotton surrounding the atomizer core. This reduces the amount of e-liquid in the oil storage cotton, helping to avoid the problem of oil leakage from the atomizer core tube caused by the oil storage cotton being completely soaked in e-liquid in existing integrated electronic cigarettes. Another key design feature is that the atomizer core is positioned higher than the horizontal level of the wicking cord's through-hole in the right chamber. This effectively raises the oil inlet point of the heating coil element, further reducing the risk of oil leakage from the atomizer core.

[0014] On the other hand, the structure of the left chamber for atomization and the right chamber for oil storage, designed in this scheme, helps to keep the e-liquid inside the right chamber from being affected by the heat generated during the operation of the atomizing core, thus helping to maintain the freshness of the e-liquid.
