Abstract

Abstract A decorative ball device mainly comprises a transparent hollow sphere which contains a liquid. A puppet together with a plurality of small pieces are disposed in the sphere. The sphere has a pump case and a skirt at its bottom. A sealing ring locates between the inner periphery of the skirt and the outer periphery of the pump case. The sealing ring has a central aperture respectively communicating with an inlet and an outlet channels in the pump case. A supporting plate for supporting the puppet is disposed in the sphere. The supporting plate possesses a pair of holes each communicating with the central aperture. The holes respectively correspond to the outlet and inlet channels. In operation, when a blade in the pump case is driven to rotate by a motor. The pieces along with the liquid are driven to circulate within the sphere thereby creating a both dynamic and attractive effect.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 266 words
A decorative ball device comprising: a transparent hollow sphere with a predetermined diameter, the interior of said sphere containing a liquid and a plurality of small pieces, said sphere having a downwardly extending annular skirt, said annular skirt having an annular opening formed therein; a pump case being disposed below the annular opening of said skirt, the interior of said pump case having a chamber which receives a blade, a guide box being integrally formed with said pump case, said guide box communicating with said chamber through a hole, said pump case having an outlet channel and an inlet channel at its top portion; a motor being mounted to one side of said pump case in such a manner that said blade in said pump case is joined with a shaft of said motor; a sealing ring being disposed between said skirt and said pump case, said sealing ring having a downward flap to tightly fit the inner periphery of said skirt and the outer periphery of said pump case, said sealing ring having a supporting plate which extends into said sphere, said sealing ring further having a central aperture respectively communicating with said outlet channel and inlet channel, said supporting plate having a pair of holes at its bottom and said holes respectively correspond to said outlet channel and said inlet channel, the top surface of said supporting plate having a puppet thereon; whereby when the liquid is driven to circulate in said sphere by said blade driven by said motor, said pieces may move with the circulating liquid flow to spread throughout said sphere.
Claim 2
Dependent Claim 266 words
A decorative ball device comprising: a transparent hollow sphere with a predetermined diameter, the interior of said sphere containing a liquid and a plurality of small pieces, said sphere having a downwardly extending annular skirt, said annular skirt having an annular opening formed therein; a pump case being disposed below the annular opening of said skirt, the interior of said pump case having a chamber which receives a blade, a guide box being integrally formed with said pump case, said guide box communicating with said chamber through a hole, said pump case having an outlet channel and an inlet channel at its top portion; a motor being mounted to one side of said pump case in such a manner that said blade in said pump case is joined with a shaft of said motor; a sealing ring being disposed between said skirt and said pump case, said sealing ring having a downward flap to tightly fit the inner periphery of said skirt and the outer periphery of said pump case, said sealing ring having a supporting plate which extends into said sphere, said sealing ring further having a central aperture respectively communicating with said outlet channel and inlet channel, said supporting plate having a pair of holes at its bottom and said holes respectively correspond to said outlet channel and said inlet channel, the top surface of said supporting plate having a puppet thereon; whereby when the liquid is driven to circulate in said sphere by said blade driven by said motor, said pieces may move with the circulating liquid flow to spread throughout said sphere.
Claim 3
Dependent Claim 53 words
A decorative ball device as claimed in claim 1, wherein a partition is disposed between said pump case and said guide box, said partition having an inclined portion which cooperates with an inclined portion of said pump case to form an outlet channel, the other side of said partition forming an inlet channel.
Claim 4
Dependent Claim 48 words
A decorative ball device as claimed in claim 2, wherein the bending point of said inclined portion of said partition is located around the central line of said sphere such that said outlet channel and said inlet channel respectively are located at each side of said central line.
Claim 5
Dependent Claim 40 words
A decorative ball device as claimed in claim 1, wherein said supporting plate of said sealing ring has a pair of narrow pieces to form at each side an arcuate hole to respectively correspond to said outlet and inlet channels.
Claim 6
Dependent Claim 34 words
A decorative ball device as claimed in claim 1, wherein at least a portion of said pump case is housed within a base seat for placing said decorative ball device on a flat surface.
