Electronic atomizing device as well as atomizer and liquid injecting structure thereof

Abstract

The invention relates to an electronic atomizing device as well as an atomizer and a liquid injecting structure of the electronic atomizing device. The liquid injecting structure comprises an outer tube and a liquid injecting assembly, wherein air exhaust holes are arranged in the outer tube; the liquid injecting assembly comprises a sleeve and a liquid injecting tube, and a liquid injecting holeis arranged in the liquid injecting tube; the liquid injecting tube is arranged in the sleeve and can move to and fro between a first position and a second position along the axial direction relativeto the sleeve; when the liquid injecting tube is at the first position, the sleeve closes the liquid injecting hole; when the liquid injecting tube is at the second position, the closing of the sleevefor the liquid injecting hole is relieved; the sleeve is arranged in the outer tube and can move to and fro between a third position and a fourth position along the axial direction relative to the outer tube; when the sleeve is at the third position, the sleeve closes the air exhaust holes; and when the sleeve is at the fourth position, the closing of the sleeve for the air exhaust holes is relieved. Due to the special configuration of the liquid injecting structure, the liquid injecting hole in the liquid injecting tube is enabled to be closer to the end face of the outer end of the liquid injecting structure, thus a liquid matrix residual in the tube after liquid injection is reduced as far as possible, and therefore, the cleaning is easier.

Description

technical field [0001] The invention relates to the field of articles for smokers, and more specifically relates to an electronic atomization device, an atomizer and a liquid injection structure thereof. Background technique [0002] Electronic cigarettes are also known as virtual cigarettes and electronic atomization devices. As an alternative to cigarettes, electronic cigarettes are mostly used for smoking cessation. E-cigarettes have a similar appearance and taste to cigarettes, but generally do not contain other harmful components such as tar and suspended particles in cigarettes. [0003] Electronic cigarettes are mainly composed of atomizers and power supply units. Existing atomizers are mainly divided into disposable atomizers and secondary atomizers that can be reinjected. After the secondary atomizer is used up, the smoke can be re-injected into the atomizer. oil and continue to use. The liquid injectable atomizer in the prior art mainly includes a liquid storag...

AI Technical Summary

Problems solved by technology

However, since the liquid injection port is usually set at the bottom of the outer tube, the depth of the liquid injection port is relatively deep, and there is a large amount of smoke oil remaining in the tube after liquid injection, which is difficult to clean

Secondly, there is no seal between the outer end of the outer tube and the liquid injection tube, which may easily cause the leakage of e-liquid, causing troubles to consumers
