Abstract
Description
Technical Field
[0001] This utility model relates to the field of aroma diffuser technology, and in particular to a high-pressure, high-volume aroma diffuser. Background Technology
[0002] Commercial high-flow aroma diffusers are often used in conjunction with shopping mall ventilation systems. Due to installation space limitations, these diffusers typically require extended air conditioning ducts to deliver the atomized fragrance into the system. Currently, most commercial high-flow aroma diffusers on the market use diaphragm pumps, with pump pressures only reaching around 30 kPa. After connecting the atomizing coil, the actual measured working pressure is only a few tens of kPa, indicating weak air pressure. When the air conditioning duct is too long, or when the duct is bent and turned multiple times due to space constraints, the atomized fragrance weakens within the duct, sometimes even resulting in no fragrance being emitted, significantly reducing machine performance. Therefore, existing aroma diffusers need optimization and improvement. Utility Model Content

[0014] The high-pressure, high-atomization aroma diffuser designed using this technical solution has at least the following beneficial effects:
[0015] By setting a high-pressure piston air pump, the aroma diffuser can output high pressure and large atomization volume. It can be connected to an air conditioning pipe, which solves the problem that the aroma mist weakens in the pipe and results in no aroma mist output when the existing aroma diffuser is connected to an air conditioning pipe.
