Document Type and Number:
WIPO Patent Application WO/2023/207422
Kind Code:
A1
Abstract:
Provided in the present application are a spraying device and a cleaning apparatus. The spraying device comprises: a liquid storage tank used for storing a liquid therein; an atomization tank, the bottom of which is provided with an overflow assembly, when the liquid in the atomization tank reaches a preset level, the liquid overflows into the liquid storage tank through the overflow assembly; a tank cover covering the atomization tank; an atomizer used for atomizing the liquid in the atomization tank into spray; a liquid inlet and spray outlet pipeline, which passes through the tank cover and is used for injecting liquid and discharging spray; and a liquid supply pump used for sucking the liquid from the liquid storage tank and pumping the liquid into the atomization tank. Compared with the prior art, the overflow assembly arranged at the bottom of the atomization box can enable liquid in the atomization box to overflow into the liquid storage box when the liquid in the atomization box reaches a preset level, and also can form a sealed spray flowing area in the atomization box, so that spray cannot enter the liquid storage box or other areas, thereby avoiding unnecessary loss of the spray amount and avoiding corrosion to electronic components.
