Abstract
An ornamental liquid color box includes stationary clear containers fixedly mounted on a cover of a seat. Propellers are provided on the seat to propel liquid colors flowing into the seat to liquid passages that are led to upper storing zones of the containers. Liquid colors sent to the upper storing zones then moves into narrowed middle display zones to form flattened and irregular drips before reaching lower storing zones of the containers and entering the seat again to complete a cycle of movement of the liquid colors in the liquid color box. The whole liquid color box need not be manually or mechanically turned to maintain continuous circulation of the liquid colors in the liquid color box. The propellers are driven to rotate by driving means that may be coil windings or a combination of a motor and magnet-loaded driving and driven gear wheels. No leakproof means, such as shaft seals, are required for the liquid color box.
Description




BACKGROUND OF THE INVENTION




The present invention relates to an ornamental liquid color box, and more particularly to an ornamental liquid color box that has stationary liquid color containers and simplified driving mechanism to easily cause liquid colors to circulate in the containers and show changeful colors and views.




The liquid color box is a popular ornament and typically includes a transparent liquid color container divided into two or more spaces from front to rear side of the container. Generally, two spaces, namely, a front and a rear space, would be sufficient for the liquid color box to achieve an ornamental function thereof. Each space of the container further includes expanded upper and lower areas for storing one liquid color, and a narrowed middle area for displaying flattened and therefore differently shaped liquid color drips. Liquid colors stored in the upper storing areas flow downward to pass the middle displaying areas in a form of flattened drips that have irregular shapes. The irregularly shaped color drips in the two spaces of the container overlap one another to show changeful colors.




To enable circulation of the liquid colors in the container to provide continuous display effect, the containers of currently available liquid color boxes must be either manually or mechanically turnable. In the latter case, the liquid color containers are usually a round member and driven by motor and frictional gearing. Since the container of liquid color box usually has a certain volume and weight, it is necessary for the motor and frictional gearing to generate considerable driving force to rotate the container. Moreover, to enable the container to rotate stably without producing noise, complicate supporting seat or shaft is usually needed. As a result, conventional liquid color boxes tend to be clumsy and complicate and could not be massively produced to lower manufacture costs thereof.




It is therefore desirable to develop an improved liquid color box that eliminates drawbacks existing in the conventional liquid color boxes.




SUMMARY OF THE INVENTION




A primary object of the present invention is to provide an ornamental liquid-color box that includes stationary clear liquid containers fixedly mounted on a cover of a seat. The containers may be of any shape. Propellers are provided on the seat to propel liquid colors flowing into the seat to liquid passages that are led to upper storing zones of the containers. Liquid colors sent to the upper storing zones then moves into narrowed middle display zones before reaching lower storing zones of the containers and entering the seat again to complete a cycle of movement of the liquid colors in the liquid color box. The whole liquid color box need not be manually or mechanically turned to maintain continuous circulation of the liquid colors in the liquid color box.




Another object of the present invention is to provide the above-described ornamental liquid color box, wherein the propellers are driven to rotate by driving means that may be coil windings or a combination of a motor and magnet-loaded driving and driven gear wheels. No leakproof means, such as shaft seals, are required for these driving means in the liquid-color box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Please refer to

FIGS. 1

,


2


and


3


in which an ornamental liquid color box according to a first embodiment of the present invention is illustrated. The ornamental liquid color box in this first embodiment includes an upper part


10


for display purpose and a lower part


20


at where driving means for the liquid-color box is located.




The upper part


10


includes an outer frame


11


that may be of any suitable configuration and an inner display part


12


that is composed of two or more parallelly spaced and overlaid transparent containers


13


. Generally, a display part


12


composed of only two containers


13


would be sufficient for the ornamental liquid color box of the present invention to work well. In this specification and the accompanying figures, ornamental liquid color boxes having a display part


12


composed of two containers


13


are described and illustrated as examples. Each container


13


of the display part


12


further includes an upper storing zone


131


, a lower storing zone


133


, and a narrowed middle display zone


132


. Two different liquid colors are separately contained in the two containers


13


. Each of the containers


13


is provided at a bottom thereof with a bottom hole


134


, and outside one lateral side thereof with a tube


135


. An upper end of the tube


135


is connected to the upper storing zone


131


and a lower end of the tube


135


is led to the lower part


20


.




The lower part


20


mainly includes a cover


21


and a seat


22


. The cover


21


is provided with two inlets


211


separately corresponding to the bottom holes


134


provided at the bottoms of the two containers


13


, and two outlets


212


separately corresponding to two lower ends of the two tubes


135


. The upper part


10


is firmly assembled to the cover


21


of the lower part


20


with O-rings (not shown) provided around joints of the bottom holes


134


and the inlets


211


as well as the lower ends of tubes


135


and the outlets


212


to keep these joints leakproof. The seat


22


is the place at where the driving means for the liquid color box is located. The seat


22


includes two generally keyhole-shaped liquid-supply zones


221


each of which corresponds to a set of inlet


211


and outlet


212


that correspond to the bottom hole


134


and the tube


135


for one container


13


. When the cover


21


is closed onto the seat


22


, the two liquid-supply zones


221


are sealed to form two closed spaces with only two openings each, that is, the inlet


211


and the outlet


212


. Each of the keyhole-shaped liquid-supply zones


221


includes an expanded round portion in where a rotatable disk propeller


222


having multiple blades is disposed to upward face the inlet


211


, and a narrowed elongate portion that extends outward from the round portion to locate an outer end thereof below the outlet


212


.




The disk propeller


222


may be driven to rotate in different manners and a first one of which is shown in FIG.


1


. In the first driving manner, there is provided a rotating shaft


223


having an upper end connected to a lower center of the disk propeller


222


and a lower end having a magnetic ring


224


put around it. And, in the round portion of each keyhole-shaped zone


221


, there is formed a tubular recess


225


downward extending by a predetermined distance to form a lower wall


226


. The rotating shaft


223


and the magnetic ring


224


around its lower end are received in the wall


226


of the tubular recess


225


with the disk propeller


222


located above the recess


225


. A coil winding


227


is provided below the seat


22


with a core thereof surrounding the lower wall


226


of the tubular recess


225


. With these arrangements, the disk propeller


222


is magnetically driven to rotate in the round portion of the liquid-supply zone


221


.





FIG. 4

is an exploded perspective of an ornamental liquid-color box similar to that of

FIG. 2

but using a different and simplified driving manner to drive the disk propellers


222


to rotate. In this second type of driving manner, the two disk propellers


222


have a plurality of first magnets


34


spaced on their bottom surfaces and are directly disposed in the round portions of the liquid-supply zones


221


formed on the seat


22


. And, there are provided below the seat


22


a single motor


30


, a driving gear wheel


31


connected to a top of a rotating shaft of the motor


30


, and two driven gear wheels


32


separately meshing with the driving gear wheel


31


and therefore being brought to rotate along with the diving gear wheel


31


. The two driven gear wheels


32


are separately located below the two disk propellers


222


and have a plurality of second magnets


33


provided on their top surfaces corresponding to the first magnets


34


of the disk propellers


222


. When the motor


30


is started, the driving gear wheel


31


rotates and brings the driven gear wheels


32


to rotate simultaneously. At this point, the second magnets


33


on the driven gear wheels


32


magnetically attract the first magnets


34


on the disk propellers


222


to rotate the latter.





FIGS. 5 and 6

illustrate a second embodiment of the ornamental liquid color box of the present invention. In this embodiment, the liquid color box includes a lampshade


11


, a display part


12


, and a lower part


20


. The display part


12


is structurally similar to that of the first embodiment of FIG.


1


and includes, for example, two transparent containers


13


each having a bottom hole


134


. A liquid tube providing two separated inner passages


135


is provided at one lateral side of the display part


12


, such that upper ends of the two inner passages


135


are separately led to upper storing zones


131


of the two containers


13


and lower ends of the inner passages


135


are led to an outlet


212


formed on a cover


21


of the lower part


20


. A wire tube


111


is symmetrically provided at another lateral side of the display part


12


corresponding to the liquid tube, so that a lower end of the wire tube


111


is connected to the lower part


20


and an upper end of the wire tube


111


is located below the lampshade


11


. Wires


112


may be extended from the lower part


20


to a light emitting means


113


under the lampshade


11


via the wire tube


111


, so that the ornamental liquid color box may also function like a lighting fixture.




To match with the liquid tube having two inner passages


135


, a seat


22


of the lower part


20


in this embodiment is formed of two keyhole-shaped liquid-supply zones


221


abutted on each other side by side. Again, each of the liquid-supply zones


221


includes a round portion for a disk propeller


222


to dispose therein and an elongate portion having an outer end corresponding to the lower end of one inner passage


135


. A driving gear wheel


31


connected to a top of a rotating shaft of a single motor


30


and a driven gear wheel


32


meshing with the driving gear wheel


31


are separately provided in the seat


22


below the disk propellers


222


. First magnets


34


are provided at bottom surfaces of the disk propellers


222


and second magnets


33


at top surfaces of the gear wheels


31


,


32


. When the motor


30


is started, the driving gearwheel


31


and the driven gear wheel


32


rotate synchronously to magnetically drive the disk propellers


222


to rotate.




With the above-described arrangements, a circular path for liquid color is formed for each container


13


, starting from the upper storing zone


131


and then sequentially passing the narrowed middle display zone


132


, the lower storing zone


133


, the bottom hole


134


, the inlet


211


, the liquid-supply zone


221


, the disk propeller


222


, the outlet


212


, and the liquid tube or inner passage


135


, and finally returning to the upper storing zone


131


. When the disk propellers


222


are driven to rotate in the liquid-supply zones


221


in either manner as earlier mentioned, liquid colors in irregular drip form moving from the upper storing zones


131


to the lower storing zones


133


via the middle display zones


132


and into the liquid-supply zones


221


via the bottom holes


134


and the inlets


211


are propelled by the blades on the rotating disk propellers


222


to move into the elongate portions of the liquid-supply zones


221


and be sent into the liquid tubes or inner passages


135


via the outlets


212


to flow back into the upper storing zones


131


again. As a result, the liquid colors are kept flowing continuously round the liquid color box. Meanwhile, since the middle display zones


132


are largely narrowed in their depth (or thickness) compared to the upper and the lower storing zones


131


,


133


, liquid color drips flowing therethrough are flattened into irregular shapes. The irregularly shaped liquid colors in the two display zones


132


overlap one another to create changeful colors and accordingly very good ornamental effect.




The liquid color box of the present invention is characterized in that all components included in the liquid color box to form the circular path are stationary, except the disk propellers


222


and that no leakproof means are required for any types of the driving means. The liquid color box of the present invention can therefore be positioned in a stable manner without producing noise, compared to the conventional liquid color boxes that must be entirely rotated manually or by a motor.




It is noted that the display part


12


may be of any shape without any limitation so long as a circular path for the liquid colors can be maintained. For example, it is possible for the narrowed middle display zone


132


of the display part


12


to be a curved zone. And, by properly determining a total volume of the liquid color for each container


13


, it is possible to omit the upper storing zone


131


and let the tube


135


be directly connected to the display zone


132


.
