ABSTRACT:
BACKGROUND OF THE INVENTION
a) Technical Field of the Invention
The present invention relates to a structure of a shade for a candle, and in particular, a shade body and a covering plate, both provided with a plurality of auxiliary openings and a plurality of through holes respectively. The covering plate can be rotated with respect to the shade body until the openings and the holes are aligned so that state of burning candle within the container body can be regulated.
b) Description of the Prior Art
FIGS. 5
shows a conventional candle shade having a container body
30
with an open end having a stepped ring
31
to accommodate a shade body
40
. This structure prevents the blowing of strong wind which will extinguish the burning candle within the container body.
This conventional structure allows the burning candle to burn in a very stable manner and the hot air of the burning candle is kept within the container body
30
. This structure is effective in lighting the wick of the candle during winter. However, in such conventional design, a center opening
32
is provided to the shade body
40
so that the flame of the candle can reach outside the container body, and a plurality of apertures
33
are provided along the circumferential edge of the shade body
40
. As shown in
FIG. 6
, hot air rises and the hot air is dispersed out via the center opening
32
. In this case, the speed of dispersion of hot air is slow. In summer, due to the hot air which is accumulated at the top portion of the container body
30
, the top part of the candle will be melted and at this instance, the wick
34
of the candle will become longer and the flame of the burning becomes larger. As shown in
FIG. 7
, the flame will move in accordance with the convection of air. As a result, the flame may be blown so close to the container body
30
which will damage the wall of the container body
30
. In addition, the melted wax may flow out of the container body
30
, which further causes a danger to the user.
SUMMARY OF THE INVENTION
To save the aforementioned problems, it is an object of the present invention to provide a structure of a shade for a candle, wherein the through holes provided on the covering plate can be adjusted to correspond with the auxiliary openings of the shade body so as to provide an optimum size of the opening for air passage, which in turn, provide convection air for the burning candle, thereby the effectiveness of candle burning is obtained.
Yet another object of the present invention is to provide a structure of a shade for a candle, wherein a plurality of protruded decorative discs are provided along the edge of the covering plate, adjacent to the through holes, thereby an aesthetic appearance for a candle shade is thus obtained.
Yet another object of the invention is to provide a structure of shade for a candle which is comparatively compact and light in weight.
Other objects, features and advantages of the invention will be apparent from the following description when read with reference to the accompanying drawings.
