Abstract

An electronic fountain candle, comprising a transparent or semitransparent outer cylinder (9), a battery compartment, a flow-guiding cover (10), an LED/water pump assembly (4), and a control board (3). A water storage chamber is located at the interior wall of the outer cylinder (9), above the bottom of the battery compartment. The LED/water pump assembly (4) is mounted inside the water storage chamber, and comprises: an LED-PCB board (42) for an LED, as well as a water pump (43) and a water drainage pipe (41). The LED-PCB board (42) is waterproofed, and the water outlet of the water pump (43) is connected to the water drainage pipe (41). The flow-guiding cover (10) is provided with a flow-guiding hole, and the water drainage pipe (41) is in communication with the flow-guiding hole. The peripheral edge of the flow-guiding cover (10) is lower than the upper end face of the outer cylinder (9), and there is a gap, used for draining water, between the flow-guiding cover (10) and the inner wall of the outer cylinder (9). The control board (3) is mounted inside the battery compartment, and the LED/water pump assembly (4) is electrically connected to the control board (3).

First claim

The invention claimed is:

1. An electronic fountain candle, comprising:
an outer cylinder resembling a candle body;
a battery compartment;
a flow guiding frame;
an LED-pump assembly; and
a control panel, wherein:
the outer cylinder includes a hollow interior,
the battery compartment has an inverted cup-shaped body with an opening that faces downward and a cup bottom that faces upward, the battery compartment disposed within the hollow interior of the outer cylinder,
the LED-pump assembly is positioned within a water storage chamber and comprising a circuit board and an LED, the LED-pump assembly further coupled to a water pump and a water drainage pipe, wherein an outlet of the water pump is coupled to the water drainage pipe,
the flow guiding frame comprises a flow guiding hole and a flow guiding cover, wherein the flowing guiding hole is in communication with the water drainage pipe, and wherein
a first gap for water drainage is provided between the flow guiding cover and the inner wall of the outer cylinder, the flow guiding cover including a sloped surface that tilts downwards as the surface extends from a center of the flow guiding cover toward the inner wall of the outer cylinder to allow water to flow from the flow guiding hole to the water storage chamber via the first gap,
the flow guiding frame further comprising an upper peripheral edge protruding upwards to secure the flow guiding cover and a lower peripheral edge protruding downwards toward the inner wall of the outer cylinder, both the upper peripheral edge and the lower peripheral edge being lower than an upper end surface of the outer cylinder, wherein a second, smaller gap for water drainage is provided between the lower peripheral edge and the inner wall of the outer cylinder such that the lower peripheral edge is configured to prevent water from splashing through the first gap, and
the control panel is electrically connected to the LED-pump assembly.

2. The electronic fountain candle of claim 1 , further comprising a hollow flow guiding column for water drainage, wherein one end of the flow guiding column is in communication with the water drainage pipe and the other end of the flow guiding column is connected to the flow guiding cover and is in communication with the flow guiding hole.

3. The electronic fountain candle of claim 2 , wherein the water storage chamber is disposed within the hollow interior of the outer cylinder and accommodates that the LED-water pump assembly within the water storage chamber.

4. The electronic fountain candle of claim 3 , further comprising a battery base, wherein the control panel is electrically connected to the battery base.

5. The electronic fountain candle of claim 4 , wherein:
the battery compartment comprises a battery base that extends outwards to form a platform surrounding the opening of the battery compartment,
an outer diameter of the platform is greater than the outer diameter of the battery compartment, and
the platform is tightly coupled to the outer cylinder.

6. The electronic fountain candle of claim 3 , wherein the water storage chamber and the battery compartment are integrated to form one unit.

7. The electronic fountain candle of claim 1 , wherein the flow guiding cover is circular in shape, and the flow guiding hole is located in the center of the flow guiding cover.

8. The electronic fountain candle of claim 7 , wherein a top point of the upper surface of the flow guiding cover is vertically lower than the upper end of the outer cylinder.

9. The electronic fountain candle of claim 1 , further comprising an atomization circuitry disposed within the water storage chamber and electrically connected to either the circuit board of the LED-pump assembly or to the control panel.

10. The electronic fountain candle of claim 1 , wherein the LED-pump assembly further comprises a tray, wherein the circuit board of the LED-pump assembly is mounted on the tray, and the water drainage pipe passes through a section of the tray.

11. The electronic fountain candle of claim 1 , wherein:
the flow guiding cover comprises a paraffin wax coating layer, wherein
the paraffin wax coating layer covers an upper face of the flow guiding frame and extends to the upper peripheral edge.

12. The electronic fountain candle of claim 1 , wherein the water storage chamber is disposed over the battery compartment.

13. The electronic fountain candle of claim 1 , wherein an inner wall of the outer cylinder is positioned on the bottom of the battery compartment and includes a water storage chamber body.

14. The electronic fountain candle of claim 1 , wherein the LED-pump assembly is water-proof.

15. The electronic fountain candle of claim 1 , further comprising at least one wax loading hole, through which wax can be loaded into at least part of the hollow interior of the outer cylinder in vicinity of an inner wall of the outer cylinder.

16. The electronic fountain candle of claim 1 , further comprising at least one groove to accommodate wax that is poured into at least part of the hollow interior of the outer cylinder.

17. The electronic fountain candle of claim 1 , wherein the LED-pump assembly includes a first electrode and a second electrode positioned at different heights such that the LED-pump assembly only operates when water in the water storage chamber submerges both the first electrode and the second electrode.
