Embodiment Construction

[0020] The specific implementation process and implementation effects of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 and figure 2 As shown, a novel air flow preheating device includes a heating tube 1 and a draft tube 2, the heating tube 1 and the draft tube 2 are hollow cylinder structures, the lower end of the draft tube 2 is open and the upper end is closed, The upper and lower ends of the heating tube 1 are open; the guide tube 2 is nested in the heating tube 1, and the tube wall length of the guide tube 2 is less than or equal to the length of the heating tube 1; The length of the flow tube 2 is determined by the product characteristics of the electronic cigarette. Such as image 3 As shown, the heating tube 1 adopts a ceramic heating element, the heating tube is connected to a heating circuit, and a temperature sensor 7 is arranged on the outer wall of the heating tube 1, and the tem...

Abstract

The invention discloses a novel airflow preheating device, which comprises a heating tube and a flow guide tube. The outer wall of the tube is provided with a spiral guide vane, and the lower end wall of the guide tube is provided with airflow holes; the inside of the guide tube is provided with a vent tube, which is a hollow tube with openings at both ends; the outer diameter of the vent tube is smaller than that of the draft tube The inner diameter of the airflow tube forms an air flow space between the outer wall of the air duct and the inner wall of the air guide tube; the maximum outer diameter of the spiral guide vane on the outer wall of the air guide tube is less than or equal to the inner diameter of the heating tube; It enters the area between the inner wall of the draft tube and the outer wall of the ventilation tube, and then enters the space formed by the outer wall of the draft tube and the inner wall of the heating tube through the air hole on the wall of the draft tube, and guides the airflow from bottom to top through the spiral guide vane. Outflow from the tip of the draft tube. The airflow preheating device of the present invention adopts an optimized airflow channel, so that the outer wall of the electronic cigarette is not easy to generate heat.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a novel airflow preheating device. Background technique [0002] In today's society, e-cigarettes have gradually developed as a substitute for traditional cigarettes; e-cigarettes generally use e-liquid as a raw material to atomize and generate smoke, which cannot replace traditional cigarettes in terms of taste; If it cannot be fully smoked, it will produce too many harmful substances. Cigarettes can be fumigated and distilled through the heating device, which can reduce the generation of harmful substances and achieve the effect of smoking real cigarettes. [0003] In the prior art, fumigated cigarettes include an airflow preheating device to heat the incoming airflow for the next step of introducing the hot airflow into the cigarette for distillation. However, due to the unreasonable design of the airflow channel in the existing airflow preheating d...
