Title: Water curtain simulated candle lamp

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to an electric lamp and, more particularly, to a water curtain simulated candle lamp using water curtain projection to simulate flame dynamic effect. 
     2. Description of Related Art 
     In today&#39;s society, traditional lighting tools, such as candles and oil lamps, have already replaced by various electric lamp. But in some particular occasions or special situations, candles and oil lamps that still have traditional meanings and special visual effects could not be replaced by lighting tools used in today&#39;s daily life. For example, incense and candles are often used in worship of deities and ancestors, shaking candle fire may be regarded as memory for ancestors and expectations for future generations. Or in some occasions needing specific atmosphere, shaking effect of candle fire may also cause different visual perception. However, traditional lamps, such as candles, oil lamps, have security concerns due to flame. Combustible objects around may be easily fired when a traditional lamp is upset by wind or human factors. Thus, simulated candle lamps have been developed. 
     In the market, most simulated fire electric lamps simulate flame perception by lightening up a flame-shaped plate body, more than this, electric drive devices such as motors are used for driving objects to move or shake to achieve the dynamic effect of simulating fire. 
     Those simulated candle electric lamps are provided to replace lighting objects such as candles and oil lamps, and they may be used as nice decorative lighting with beautiful design of appearance. More functional designs may highly improve the quality of life and it is a subject at the present stage, the inventor finally completes the present invention after numerous improvements. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a water curtain simulated candle lamp, which simulates visual perception of dynamic candle lamp by using water curtain projection. 
     Another object of the present invention is to provide with incense, suitable perfume source added into water may gradually volatile in the air when water curtain is sprayed, to achieve the purpose of improving the quality of life and the environment. 
     To achieve the object, the water curtain simulated candle lamp of the present invention, its main elements and technical means includes a base body, a cover body, a spraying device, a light source and a floating wick; wherein, a water container is set above the base body, an upper opening is set on the water container; the cover body is set on the upper opening or a relative upper position of the upper opening for covering the upper opening, and includes a concave upper surface, a spacing hole is set on a concave end of the upper surface; the spraying device includes a pump and a spray pipe, the pump is set inside the water container and a outlet is connected to an end of the spray pipe for pressurizing water into the spray pipe, an water injector is set on another end of the spray pipe, which is located in a corresponding position of the spacing hole, so that water may be sprayed upwards to form a water curtain shown outside of the cover body; the light source set on the water injector is used to light up the sprayed water curtain; the floating wick set inside the spray pipe is provided to move up and down with water flow, and an top end of the floating wick is protruded the water injector to form a wick of simulating candle lamp. 
     Whereby, water curtain projection effect may be achieved through water spraying and lighting by the light source, and the floating wick floats and protrudes with water flow to achieve dynamic perception of simulated fire burning. Spraying water may centralize inwards via concave upper surface of the cover body and flow back to the lower water container through the spacing hole. A complete recycling is achieved. Furthermore, suitable essence or perfume source could be added or dissolved in water to improve the environmental quality.
