TECHNICAL FIELD
The present invention relates to the technical field of aromatherapy diffuser, and particularly to a functionally modular aromatherapy diffuser.
BACKGROUND
With the popularity of an aromatherapy diffuser in daily life, a core atomization function of the aromatherapy diffuser has put higher requirements on the durability of an air pump. Currently, the aromatherapy diffuser generates negative pressure by high-frequency driving of an air pump, and atomizes a liquid aromatherapy agent into micron-sized particles. As a core power component, the air pump needs to bear high-load operation for a long time. However, carbon brushes and bearings of a motor inside the air pump are prone to metal fatigue and wear under continuous friction, causing the motor speed to decay or even stop. Meanwhile, an air pump drive circuit is exposed to a high-temperature and high-humidity environment for a long time, and components such as an electrolytic capacitor and a power transistor are prone to thermal aging and oxidation corrosion, causing power supply fluctuations or control signal distortion, and ultimately causing problems such as reduced atomization efficiency and abnormal noise.
In the prior art, the aromatherapy diffuser generally adopts an integrated design of an air pump and a main unit, and an air pump housing is rigidly connected to components such as an atomization chamber and a main control board through welding, bolting or gluing. This structure enables a compact layout but has significant defects: when the air pump fails due to wear or circuit aging, it is difficult for users to disassemble and replace the air pump without damaging a main unit housing or adjacent components, resulting in high maintenance costs and serious waste of resources.
Therefore, there is an urgent need for a modular air pump design solution to lower the maintenance cost and extend the service life of the entire diffuser.
