Diffuser

Abstract

The invention discloses an aroma diffuser, which comprises a liquid storage device, a housing provided with an installation chamber, an air supply device, and a sealing member. The liquid storage devices are all arranged in the installation chamber and communicate with each other, the air supply device, the liquid storage device cooperate with the housing to form a return air channel, and the seals are arranged on the liquid storage device and the Between the air supply device, and the sealing member is located on the return air channel and is in sealing contact with the outer shell. Therefore, the air return passage can be blocked by the sealing member, so as to prevent the aromatherapy gas generated by the diffuser from flowing back into the air supply device from the return air passage, thereby reducing the concentration of the aromatherapy gas released into the environment, This further affects the use effect of the aroma diffuser, and at the same time prevents the acidic aromatherapy gas from entering the gas supply device to corrode the structural components, reducing the reliability of work and affecting the service life.

Description

technical field [0001] The invention relates to the technical field of gas diffusion devices, in particular to a fragrance diffuser. Background technique [0002] Aroma diffuser is a kind of liquid aromatherapy liquid or essential oil converted into aerosol by heating or ultrasonic vibration, and pumped into the surrounding air through high-pressure gas for people to breathe, so as to accelerate metabolism and promote Cell regeneration, enhance immunity and other health effects. At present, the aroma diffuser on the market generally adopts the structure of an air pump and a specific nozzle. Its working principle is to generate high-speed airflow through the air pump, and create a low-pressure environment in a local area to generate a pressure difference, so that the aerosol essential oil is brought to the air through the airflow. At the nozzle, and then enter the external environment from the air outlet of the diffuser to realize the function of ambient fragrance expansion....

AI Technical Summary

Problems solved by technology

Usually, the air outlet of the aromatherapy container and the air inlet of the air pump in the aroma diffuser using the above working principle are connected to each other, so that the scented air flow will diffuse to the installation area of ​​the air pump and be sucked back by the air pump, thereby Greatly reduce the concentration of aromatherapy gas sprayed from the outlet of the diffuser, which will affect the working effect of the diffuser

At the same time, when the aromatherapy liquid of the aerosol pile enters the air pump, or when the aromatherapy container is tilted or inverted so that the aromatherapy liquid (essential oil or perfume) directly contacts the air pump, the air pump components will be corroded and cannot work properly because the aromatherapy liquid is acidic , which greatly affects the service life of the diffuser
