Light and shadow water ball structure
View Patent ↗A light and shadow water ball structure mainly includes a seat body, water ball and projector, where the water ball is fixed to the seat body, and the projector includes a projection seat and grating sheet; the projection seat is configured on one side of the water ball, and the inside of the projection seat is provided with a projection passage, where one end of the projection passage is formed an opening, the inside of the projection passage is provided with a light-emitting element and grating sheet spaced from each other, and the grating sheet has a pattern projected on an object outside the seat body through the light emitted from the first light-emitting element.
1. A light and shadow water ball structure, comprising:
a seat body, having an electric control unit comprising a power source configured inside said seat body and a first light-emitting element in electric connection with said power source;
a water ball, being a transparent three-dimensional shape, fixed to said seat body, and flowable liquid filled inside said water ball; and
a projector, comprising a projection seat and grating sheet, said projection seat configured on one side of said water ball, and an inside of said projection seat provided with a projection passage, one end of said projection passage formed an opening, said first light-emitting element configured on a bottom of said projection passage, said grating sheet configured on said projection passage, and having a space from said first light-emitting element, said grating sheet having a pattern, and said pattern projected on an object outside said seat body through light emitted from said first light-emitting element.
2. The structure according to claim 1 , wherein said projector further comprises a convex lens fixed to said opening of said projection passage, and said convex lens is spaced from said grating sheet.
3. The structure according to claim 1 , wherein said pattern is through holes passed through a thickness of said grating sheet.
4. The structure according to claim 1 , wherein said grating sheet is transparent, an inner surface or outer surface thereof is provided with a coating layer, and said pattern is configured on said coating layer.
5. The structure according to claim 1 , wherein said electric control unit further comprises a circuit board, second light-emitting element and switch configured on said seat body, and said power source, second light-emitting element and switch are respectively in electric connection with said circuit board.
6. The structure according to claim 1 , wherein a motor with a magnetic rotating shaft is provided inside said seat body, said motor is in electric connection with said power source, a magnetic rotating element is provided inside said water ball, and said rotating element is magnetically attracted by said magnetic rotating shaft to rotate therewith.
