Atomiser and electronic atomising device

By using a Tesla valve-like flow-guiding and noise-reducing component in the atomizer, the noise problem during heating of the atomizing device is solved by utilizing the destructive interference of sound waves in the main flow channel and the branch flow channel, thus achieving a balance between improving quiet performance and ensuring smooth airflow.

AI Technical Summary

Technical Problem

When the atomizing equipment is working, the atomizing matrix is ​​heated and boiled to produce bubbles. The bursting of these bubbles causes significant bursting noise, which affects the product's quietness. This noise problem is even more pronounced when the heating power is increased to improve the amount of mist produced.

Method used

A flow-guiding and noise reduction component with a Tesla valve-like structure is formed by combining a first main flow channel and at least two first branch flow channels. Sound waves are dispersed and propagated through the main flow channel and branch flow channels, and destructive interference is generated when they converge, thereby reducing the noise intensity.

Benefits of technology

It effectively reduces the noise propagation intensity of the atomizer, improves the product's quietness, and at the same time ensures smooth airflow and the atomizer's flavor.

Abstract

The application discloses an atomizer and an electronic atomization device. The application adopts a first main flow channel and at least two first branch flow channels to form a flow guide and noise reduction assembly with a Tesla valve structure. External airflow can flow into the gap between the shell assembly and the suction nozzle shell and flow to the atomization cavity through the first main flow channel, thereby ensuring the smoothness of airflow when the atomizer is used. When the sound wave generated in the atomization cavity reversely propagates to the direction of the flow guide and noise reduction assembly, the sound wave enters the two first branch flow channels through the first main flow channel and is dispersedly propagated. Since the two first branch flow channels are staggered along the length direction of the first main flow channel, the sound wave dispersedly propagated forms a difference in the propagation path length, and then a phase difference is generated. The multi-path sound waves with the phase difference converge in the first main flow channel, which produces destructive interference, so that the amplitudes of the sound waves outwardly propagated are mutually offset, and the intensity of the sound wave propagated to the outside of the shell assembly is greatly reduced, thereby improving the product mute performance of the atomizer.
