The present disclosure discloses a wall mount base device. The wall mount base device comprises a wall mount bracket and a hanging member configured to be hung on the wall mount bracket. The wall mount bracket is disposed with a hanger, and the hanger comprises a locking groove. The hanging member is disposed with a locking mechanism, and the locking mechanism comprises one or more locking members, a transmission mechanism, and an operating member. The hanging member is configured to detachably cooperate with and encompass an outer side of the hanger, and the hanger cooperates with and is encompassed in the hanging member disposed on an outer side of the hanger. When the one or more locking members are disposed at the locked positions, the one or more locking members are disposed in the locking groove to enable the hanging member to be locked to the wall mount bracket.

Provided is a liquid jetting device for skin cleaning configured to clean a skin using liquid droplets generated from a jetted continuous flow, wherein the liquid jetting device includes a jetting nozzle having a plurality of jetting nozzle holes. Further, an interval between each of the plurality of jetting nozzle holes is 1 mm or smaller, and a diameter of the jetting nozzle hole is in a range from 0.02 mm to 0.1 mm.
