For a long time around the world, the conventional candle has evolved from purely illuminant to decoration and ambient creation in festivals, events, religious ceremonies and home decoration. The conventional candle has become an integral part of daily life in many households.
On the other hand, the conventional candle can cause potential air pollution, darkens surrounding area, and even cause fire. Therefore, an electronic candle is developed to use light-emitting element in a candle-shape structure to replace the burning flame in the conventional candle.
However, because the main body of the known electronic candles is often manufactured by inject molding, and then a process of etching, transfer printing or electroplating is used to process the inner and outer surfaces. The inner surface processing is not only complex but also time-consuming, and is prone to poor yield rate. Therefore, the problems of complexity, time consumption and poor yield rate of the two-time manufacturing process of the known electronic candle make the products less competitive in the mark.
SUMMARY OF THE INVENTION
The primary purpose of the present invention is to solve the problems of complexity, time consumption, poor yield rate and low competitiveness of the two-time manufacturing process of the known electronic candle.
Thus, to achieve the above object, the present invention provides a decorative candle with inner pattern, mainly including: a candle main body with inner pattern, made of light-transmittable plastic material, having at least an inner surface and an outer surface, the outer surface being smooth, the inner surface having a plurality of predefined patterns, the candle main body and the patterns being monolithically formed by blowing; and a light-emitting device, disposed inside the candle main body with pattern, having at least a light source and an electrical box for providing power to the light source.
As such, in the decorative candle with pattern of the present invention, the patterns on the inner surface and the candle main body are monolithically manufactured by blowing, and thus the problems associated with the conventional two-process manufacturing are eliminated.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
As shown in FIGS. 1 to 3, the first embodiment of the decorative candle with inner pattern includes: a candle main body with inner pattern 1 and a light-emitting device 2.
The candle main body with inner pattern 1 is made of light-transmittable plastic material, and has at least an inner surface 11 and an outer surface 12, wherein the outer surface 12 is a smooth surface and the inner surface 12 includes a plurality of predefined patterns 111. In the present embodiment, patterns are continuous and repetitive. However, non-continuous or non-repetitive patterns can also be used. The candle main body 1 and the patterns 111 are monolithically formed by blowing. The outer surface further 12 includes a top 121 and a bottom 122, wherein the top 121 includes a concave part 123 and the light-emitting device 2 is disposed inside the concave part 123. The light-emitting device 2 includes a light source 24 and an electrical box 21 for providing power to the light source 24. In the present embodiment, the light source 24 is a light-emitting diode (LED). A switch 22 and a shade 23 are disposed externally to the electrical box 21. The electrical box 22 houses a circuit board 25. The switch 22 can control the ON and OFF of the light source 24. Because the light-emitting device 2 can use various power sources and light sources, the present embodiment does not describe in details here.
As shown in FIG. 4, the outer surface 12 of the candle main body with pattern 1 can further includes a plurality of patterns 124. The patterns 124 on the outer surface 12 can be formed monolithically with the candle main body with inner pattern 1, or formed by etching, electroplating, painting, and so on. The patterns 124 can be different from the patterns 111 on the inner surface 11 of the candle main body with inner pattern 1 so that the inner surface 11 and the outer surface 12 in the present embodiment can display different decorative effects.
Refer to FIGS. 5-7 for the second embodiment of the present invention.
The candle main body with inner pattern 1 further includes a light-transmittable bottom cover 13, fixedly engaged to the bottom 122 of the candle main body with inner pattern 1. In the present embodiment, the bottom cover 13 is glued to the bottom 122 of the candle main body with inner pattern 1. Also, the candle main body with inner pattern 1 and the bottom cover 13 form a hollow housing chamber 14, able for filling with a flowing fluid doped with glittering bits 141. Furthermore, the bottom cover 13 of the candle main body with inner pattern 1 is connected to a base 3. The base 3 includes a concave trench 31 corresponding to the bottom cover 13 of the candle main body with inner pattern 1. The concave trench 31 id disposed with two LEDs 32 at the bottom. The outer circumference of the base 3 is disposed with a switch 33, and the switch 33 is electrically connected to the power source (not shown) and LEDs 32.
Therefore, when pressing the switch 33 of the base 3, the power form the power source propagates to the LEDs 32 through the switch 33 so that LEDs 32 can emit light, and the light passes through the bottom cover 13, the fluid doped with glittering bits 141 inside hollow housing chamber 14 and the outer surface 12 to project onto the outside.
