Description

spray device

【Technical field】

The present invention relates to a spray device, and more particularly, to a spray device with an indirect spray unit.

【Background technique】

Desktop air humidifiers are often used in dry climates to increase air humidity by atomizing the liquid in the humidifier. Generally speaking, the above-mentioned atomization process needs to atomize the liquid into droplets with smaller particle size to avoid the phenomenon that the sprayed droplets are too large and cause excessive wetness. In the traditional method, a high-frequency oscillation plate is used to oscillate in the liquid at high speed to atomize the liquid. However, the thermal energy generated during the oscillation may cause the machine to overheat and increase the risk of machine failure; on the other hand, If liquids with additives are used (eg, essential oils, fragrance-added liquids, etc.), the generation of thermal energy is more likely to cause deterioration of these liquids.

In view of the above problems, there is a need to provide a spray device that can effectively atomize liquid into droplets of smaller particle size without generating excess heat energy.
