Description

Double-airway aerosol generating device

Technical Field

Background

The aerosol is a colloid dispersion system formed by dispersing and suspending solid or liquid small particles in a gaseous medium, and the aerosol can be absorbed by a human body through a respiratory system, so that a novel alternative absorption mode is provided for users. Nebulizers refer to devices that form aerosols from stored nebulizable media by means of heat or ultrasound, etc. Nebulizable media include nicotine (nicotine) -containing solutions, medical drugs, skin care emulsions, etc., which are nebulized to deliver an aerosol for inhalation to the user, replacing conventional product forms and absorption modalities. The common electronic atomization device mainly comprises an atomization assembly and a power supply assembly, wherein the atomization assembly is a core assembly of the electronic atomization device, an oil storage cavity is formed in the atomization assembly, atomized liquid is stored in the oil storage cavity, the power supply assembly is used for supplying power to the atomization assembly, and after the atomized liquid in the oil storage cavity is heated and evaporated to generate aerosol, the aerosol is sucked by a user through an air passage.

When the atomized liquid is thick or has high viscosity, the smoke liquid easily seeps into the middle of the air passage to block the hole, the air passage is blocked, and the microphone cannot be started to perform normal suction work; in order to solve the problem of air blocking of a single air passage, a key, preheating and heating mode is adopted, so that the cost of the key and a circuit board can be increased, and the problems of increased internal volume of the atomizing device, increased length of the atomizing device and the like can be caused. In addition, if the problem of weeping occurs, there is the risk of drowning, the bubble of dying the miaow head, leads to whole atomizing device to become invalid, and circuit board and battery also have the risk of bubble oil, lead to electrical apparatus short circuit, discharge, the risk of inefficacy.
