In known solutions, a collection reservoir is typically provided below the spray assembly to collect condensate or leakage fluid in the spray chamber or inlet. The collection tank can effectively prevent liquid from leaking out and causing corrosion to other components.

However, not only does this take up space inside the electronic spray device, thereby increasing the size of the electronic spray device, but condensation may also leak from the connection between the spray assembly and the collection tank. In addition, condensate flowing into the collection tank cannot be reused, resulting in waste.
