Electronic cigarette heating core

Abstract

The invention discloses an electronic cigarette heating core, and belongs to the technical field of electronic cigarettes. The electronic cigarette heating core comprises a sealing sleeve, a sleeve head, a sleeve middle and a sleeve bottom, the left and the right of the top of the sleeve head are each perpendicularly provided with a first hole channel, the left and the right of the lower portion of the sleeve head are each horizontally provided with a second hole channel, the middle of the sleeve middle and the middle of the sleeve bottom are a main air channel, and the upper portion of the main air channel is communicated with the first hole channels and the second hole channels; a first annular groove is formed in the center of the top of the sleeve bottom, and a second annular groove is formed in the side edge of the top of the sleeve bottom. The electronic cigarette heating core has the advantages that in the air channel, the first hole channels and the second hole channels are mutually staggered, air can flow smoothly, and cigarette tar can be prevented from entering; by means of the first annular groove formed in the sleeve bottom, redundant cigarette tar heaped on the joint of the sealing sleeve and an electronic cigarette shell is reduced, the aging speed of the sealing sleeve is decreased, and leakage of the cigarette tar is prevented; the second annular groove is combined with an original groove, and sealing is achieved through a sealing ring which is made of materials harmless to a human body, so that the sealing performance of the heating core is particularly good.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a heating core of an electronic cigarette. Background technique [0002] At present, existing electronic cigarettes are becoming more and more common in the market, and their internal structures tend to be more and more diversified. However, the internal structural components of the one-piece electronic cigarette are basically similar, and the structure of the sealing sleeve is as follows: image 3 Shown, and commonly used silicone material. This type of structure generally has various forms of oil leakage problems, including oil leakage from the airway, oil leakage from the seal, and oil leakage from the suction nozzle. A lot of effusion or unnecessary violent collision will cause the liquid to enter the airway and flow out of the electronic cigarette along with the airway, causing inconvenience or pain to the user.
