CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application is the US national stage of International Patent Application PCT/CN2014/085078 filed on Aug. 25, 2014. 
     TECHNICAL FIELD 
     The invention relates to combination of a lighting article and other articles, especially a device and system that can realize a dynamic visual effect due to the structural combination of the lighting article and the other articles; and particularly the invention relates to a method and device for an electric candle to simulate a flame and to realize dynamic visual effect. 
     BACKGROUND ART 
     In the modern society, people will always create and set off a romantic atmosphere by contrast with the aid of lighting candles on the occasion of a wedding ceremony, a friend&#39;s party, a birthday celebration, or a restaurant, a bar, a coffee house, etc. Nevertheless, traditional candles will not only have shorter combustion duration, pollute the environment and cause wasting of resources, but also will be harmful to people&#39;s health, moreover easily lead to a fire, therefore, simulation flames and simulation electric candle devices are more and more popular. 
     The simulation electric candle devices with prior art adopt the flame-shaped electric bulbs, so as to control lamp-light flickers thereof and to simulate dynamic flames. However, in this way, only the illumination of dynamic flames is simulated, moreover the appearance of the flames thereof is not real enough. The technical solution disclosed by the U.S. Pat. No. 8,070,319 B2 has preferably simulated the dynamic flames, with lively images. However, the pendulum-like candle flame simulating object thereof can only keep pushing by virtue of the electromagnetic force, applying it to the modeling of candle holder combined with water, the electromagnetic drive mechanism thereof requires complicated waterproof sealing design, and thus has greater technical difficulty and higher cost. 
     CONTENT OF THE INVENTION 
     The present invention aims to rectify the deficiencies of the prior art so as to provide a method and device of simple structure and low fabrication cost that enables the flame of an electric candle to render a dynamic visual effect. 
     The present invention provides a first method for an electric candle to realize visual effect of a dynamic flame, the first method comprising following steps: 
     A. installing a removable upper cover on at least one cylindrical shell with only one open end and with a tubular candle flame simulating object holder fixed at a central part of the upper cover, vertically mounting candle flame simulating object onto the candle flame simulating object holder by aid of a pivot, so as to allow the candle flame simulating object to swing vertically; 
     B. enabling the candle flame simulating object to pass through a central through hole of the upper cover, and extending a head part of the candle flame simulating object to outside the upper cover; 
     C. installing a Light Emitting Diode lamp on a vertical wall of the holder and located at the lower front of one lateral plane of the head part of the candle flame simulating object, such that the light rays of the Light Emitting Diode lamp upwardly and obliquely emits to said lateral plane of the head part of the candle flame simulating object by an elevation angle β; 
     D. arranging a water stirring device at a lower part of the shell, and injecting water into the shell to immerse a tail end of a lower part of the candle flame simulating object. 
     lighting up the Light Emitting Diode lamp, and starting the water stirring device, to allow a stream of water to shoot out from a water outlet of the water stirring device and to generate fluctuations on the water filled in the shell so as to enable the candle flame simulating object to swing back and forth and the light of the Light Emitting Diode lamp to be projected to the head part of the candle flame simulating object, resulting in the visual effect of a dynamic flame. 
     Preferably, with respect to the first method, when implementing Step C, the elevation angle β of the light emitted from the LED lamp may be within a range of 20°≦β≦70°. 
     Preferably, with respect to the first method, when implementing Step A, the candle flame simulating device may be flat, with the head part thereof having a flame-like form and the lower part thereof being thicker than an upper part thereof, so as to enable the center of gravity of the candle flame simulating object to be low. A through hole may be provided in the middle of the candle flame simulating object, the through-hole being penetrated by the pivot. The candle flame simulating object may be in an upright position and can swing due to the lower part thereof being heavier than the upper part thereof. 
     The present invention further provides a second method for an electric candle to realize visual effect of a dynamic flame, the second method comprising the following steps: 
     A. installing a removable upper cover on at least one cylindrical shell with only one open end and with a tubular holder fixed at a central part of the upper cover, the holder being for holding a candle flame simulating object; vertically mounting a candle flame simulating object onto the holder by aid of a pivot so as to allow the candle flame simulating object to swing vertically; 
     B. enabling the candle flame simulating object to pass through a central through hole of the upper cover, and extending a head part of the candle flame simulating object to outside the upper cover; 
     C. installing a Light Emitting Diode lamp on a vertical wall of the holder and located at the lower front of one lateral plane of the head part of the candle flame simulating object such that the light of the Light Emitting Diode lamp upwardly and obliquely emits onto said lateral plane of the head part of the candle flame simulating object by an elevation angle β; 
     E. connecting a tail end of a lower part of the second candle flame simulating object with a horizontally positioned bottom platform coaxially and orthogonally, filling water into the shell without the water touching the bottom platform; arranging a water stirring device at or introducing an external water piping to the lower part of the shell; lighting up the LED lamp, starting the water stirring device to continuously provide a plurality of water drops onto the bottom platform so as to enable the candle flame simulating object to swing back and forth surrounding the pivot, resulting in the visual effect of a dynamic flame. 
     Preferably, with respect to second method, when implementing Step C, the elevation angle β of the light emitted from the LED lamp may be within a range of 20°≦β≦70°. 
     Preferably, with respect to second method, when implementing Step A, the candle flame simulating device may be flat, with the head part thereof having a flame-like form and the lower part thereof being thicker than an upper part thereof, so as to enable the center of gravity of the candle flame simulating object to be low. A through hole may be provided in the middle of the candle flame simulating object, the through-hole being penetrated by the pivot. The candle flame simulating object may be in an upright position and can swing due to the lower part thereof being heavier than the upper part thereof. 
     Preferably, with respect to the second method, since the tail end of the lower part of the candle flame simulating object may be coaxially and orthogonally connected with a horizontally positioned platform, although water can be filled into the shell, the water surface may not reach the platform. As the water flowing continuously onto the platform makes the candle flame simulating object out of balance, the candle flame is enabled to swing, resulting in the visual effect of a dynamic flame. 
     The present invention further provides a third method for an electric candle to realize visual effect of a dynamic flame, comprising the following steps: 
     A. installing a removable upper cover on at least one cylindrical shell with only one open end and with a tubular mounting rack fixed at a central part of the upper cover, the mounting rack being for mounting a candle flame simulating object, axially and rotatably mounting a candle flame simulating object onto the mounting rack by aid of a central through hole of a supporting seat arranged under the mounting rack, the support seat for supporting the candle flame simulating object; 
     B. enabling the candle flame simulating object to pass through a central through hole of the upper cover, and extending a head part of the candle flame simulating object to outside the upper cover;
