MICROBUBBLE PRODUCING DEVICE FOR FAUCET HAVING WATER-SAVING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2020/262763
Kind Code:
A1
Abstract:
The present invention provides a microbubble producing device for a faucet, which has a water-saving function. The microbubble producing device comprises: a first chamber having a barrel shape, which can be coupled to a tap of a water supply system or the like; a second chamber having a barrel shape, which is coupled to the lower portion of the first chamber; and a third chamber having a barrel shape, which is coupled to the lower portion of the second chamber. The first chamber has a pressurization space formed therein so as to increase the pressure and flow velocity of supplied water, and has a nozzle portion formed therein so as to discharge water having the increased flow velocity. The second chamber coupled to the first chamber has a mixing space formed therein so as to mix water discharged from the nozzle portion of the first chamber with air, and has a mixed water outlet formed therein such that the mixed water flows out therethrough. The third chamber coupled to the second chamber has a mesh member installed therein in a position spaced apart from the mixed water outlet of the second chamber by a predetermined distance, the mesh member comprising at least one mesh for producing microbubble water. The mesh member has a drain opening formed in the lower portion thereof so as to discharge the produced microbubble water. An air inflow portion is formed in coupling parts of the first chamber and the second chamber such that air flows in therethrough from the outside. A bubble discharge portion is formed in coupling parts of the second chamber and the third chamber such that internal bubbles (air) are discharged therethrough.
