AI Technical Summary

Technical Problem

The inner cavity of a traditional electronic atomization device connects various components, causing the backblowing aerosol and leakage to flow to the trigger module, contaminating the trigger module and affecting its trigger sensitivity.

Method used

An electronic atomization device is designed, and the trigger flow channel is provided in its shell, which is at least partially bent and connects the negative pressure side and the air intake hole, and communicates with the outside through the atmospheric side of the air flow sensor, reducing the chance of the air flow sensor being contaminated by backblowing aerosol or liquid leakage.

Benefits of technology

It effectively reduces the chance of airflow sensor being contaminated by backblowing aerosol or leaking fluid, and improves the trigger sensitivity and stability of the trigger module.

Abstract

The electronic atomization device comprises a shell and a control assembly, a base is arranged at one end of the shell, a suction nozzle is formed in the other end of the shell, and an air inlet hole communicating the interior and the exterior of the shell is formed in the base; the control assembly comprises an airflow sensor, the airflow sensor is arranged in the shell, the airflow sensor is provided with a negative pressure side and an atmosphere side which are arranged oppositely, and the negative pressure side faces the base; wherein a trigger flow channel is arranged in the shell, and at least part of the trigger flow channel is bent and is communicated with the negative pressure side and the air inlet hole. The base and the suction nozzle are arranged at the two ends of the shell respectively, and the negative pressure side faces the base, namely, the negative pressure side faces the side where the base is located and deviates from the side where the suction nozzle is located, so that the probability that the shell is directly impacted by aerosol reversely blown by the suction nozzle is reduced. Meanwhile, the triggering flow channel is communicated with the negative pressure side and the air inlet hole, at least part of the triggering flow channel is bent, and the extending direction of the triggering flow channel is bent and complex, so that the probability that the airflow sensor is polluted by back-blowing aerosol or leaked liquid can be further reduced.
