Title:
ANTI-REFLUX ATOMIZATION NOZZLE AND FRAGRANCE DIFFUSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/245805
Kind Code:
A1
Abstract:
An anti-reflux atomization nozzle and a fragrance diffusion device. The nozzle comprises a nozzle body (211) and a piston member (212); the nozzle body (211) is provided with a gas channel (2111) and a liquid channel (2112), the gas channel (2111) comprises a gas inlet (2111a) and a first gas outlet (2111b), the liquid channel (2112) comprises a liquid inlet (2112a) and a liquid outlet (2112b), and the first gas outlet (2111b) is used for discharging a flowing gas to form a negative pressure at the liquid outlet (2112b) and atomizing a liquid discharged from the liquid outlet (2112b); the nozzle body (211) is further provided with a piston cavity (21145), the gas channel (2111) further comprises a second gas outlet (2111c), the second gas outlet (2111c) is in communication with the piston cavity (21145), and the piston member (212) is sealingly and slidably mounted in the piston cavity (21145); when the anti-reflux atomization nozzle is in a first state (210a), the piston member (212) disables communicating between the first gas outlet (2111b) and the liquid outlet (2112b); when the anti-reflux atomization nozzle is in a second state (210b), the piston member (212) moves under the action of the flowing gas discharged from the second gas outlet (2111c) and enables communicating between the first gas outlet (2111b) and the liquid outlet (2112b). This anti-reflux atomization nozzle can prevent volatilized essential oil from entering an air pump in a non-working state.
