Reporters obtained the following quote from the background information supplied by the inventors: "Traditional candles are mainly used for illumination or in special occasions for enhancing atmosphere. The use of candles is easily affected and restricted by the environments as naked flame is used, for instance, the candle is easily extinguished if it is used in a strong wind environment, and naked flame combustion in a closed room consumes oxygen, produces harmful waste gases, and makes people feel discomfortable. Moreover, there are potential safety hazards such as fire disaster if the candle is loosely fixed at bottom or flammable material comes close to the flame. As a result, the traditional candles are gradually replaced by imitation candles.
"With the continuous development of the electric power, the candles are less used for illumination in daily life, but currently primarily used for enhancing atmosphere. Consequently, higher requirements are demanded for the imitation or simulation of the candles.
"Many imitation or simulation candles had been proposed.
"Chinese utility model patent No. 201020114356.5 discloses an electronic imitation candle lamp for fete, comprising a pedestal, a candle body and a flame device, wherein a concave cavity is provided in the center of the pedestal, a battery groove is provided in the cavity for placing batteries, a shielding cover is provided at a mouth of the cavity of the pedestal for covering the whole surface of the cavity, and the center of the shielding cover is fixedly connected with the candle body, a fan is installed in an inner chamber of the candle body, the flame device that consists of a fixed board, a flame sheet and an LED light-emitting diode is arranged on an upper end of the candle body, and the LED light-emitting diode and the fan are connected with a power supply in the pedestal via wirings to form a power supply loop. The flame portion of the imitation candle as disclosed uses the flame sheet that has a high imitation and can be driven to swing by the fan.
"Other mechanical candles that use air blowing device are described in U.S. Pat. No. 6,454,425 and U.S. Pat. No. 1,824,388.
"In U.S. Pat. No. 7,837,355, a kinetic flame device is disclosed that includes a housing with two stages of magnetic coupling of pendulum members, and a flame silhouette element is caused to move by electromagnetic force interacting between magnets on the pendulum members.
"In U.S. Pat. No. 7,159,994, a mounting system is disclosed that provides a flame shaped diffuser to have a rotary motion about two axes.
"There is a continuous demand for novel and or improved imitation or simulation candles."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "An object of the present invention is to provide a novel and or improved imitation or simulation candle that would meet the consumer demand in the market.
"In accordance with a first aspect of the present invention, there is provided an imitation candle, comprising a housing, an imitation flame body provided at a top of the housing, a light source adapted to emit light onto the imitation flame body, a swing motion device, and an air blowing device. A lower portion of the imitation flame body is connected with the swing motion device that is configured to allow the imitation flame body to pivot horizontally about at least one of a X axis and a Y axis, and comprises a wind driven pendulum member, and the air blowing device is adapted to blow air toward the wind driven pendulum member causing the wind driven pendulum member to swing as well as the imitation flame body to pivot.
"Conveniently, the wind driven pendulum member is a wind driven bowl adapted to receive blowing air, and the wind driven bowl has an air discharge hole that may be provided with an air discharge direction guide, preferably in the form of a hood attached to outside the wind driven bowl.
"Further, the wind driven pendulum member may be fixedly connected to a lower portion of a swing rod, and an upper portion of the swing rod may be fixedly connected to the lower portion of the imitation flame body.
"Separately, the swing motion device comprises a swing driving unit and a passive swing unit. The swing driving unit is operationally coupled to the passive swing unit, wherein the swing driving unit comprises the wind driven pendulum member and the passive swing unit comprises at least one of a X pivot shaft and a Y pivot shaft arranged horizontally and perpendicular to each other such that the imitation flame body is allowed to pivot horizontally about at least one of the X axis and the Y axis.
"In accordance with an aspect of the present invention, the imitation candle may further comprise an annular top cover, a swing rod, a pivot member, and a pivot support member. The configuration of the imitation candle is that the annular top cover is provided at the top of the housing, the lower portion of the imitation flame body extends through the annular top cover and is fixedly connected to an upper portion of the swing rod, a swing rod pivot hole is provided at the upper portion of the swing rod, the X pivot shaft runs through the swing rod pivot hole to be pivotally connected with the pivot member, the pivot support member is provided outside the pivot member, the pivot member and the pivot support member are pivotally connected via the Y pivot shaft provided inside the pivot support member, the pivot member is correspondingly provided with pivot holes for the Y pivot shaft, the X pivot shaft and the Y pivot shaft are arranged on the same horizontal plane, and the swing driving unit is provided at a lower portion of the swing rod.
"Conveniently, a pivot ball is provided at a top of the swing rod, and the swing rod pivot hole runs through the pivot ball. Further, the annular top cover is provided with a light penetrating hole for the light source, and preferably, a light focusing cover is fitted over the light source.
"In practice, the air blowing device would be a fan provided below the wind driven bowl, and an air outlet of the fan is positioned rightly opposite the wind driven bowl.
"In one embodiment, the imitation flame body is recessed to one side.
"In a preferred embodiment, a microprocessor circuit board and a power supply are provided inside the housing, and the microprocessor circuit board is adapted to control intensity of light from the light source and intensity of air from the air blowing device.
"Conveniently, the power supply is a battery unit provided at a bottom of the housing, and a slide power on/off switch is provided in a circuitry of the power supply. Additionally, the imitation candle further comprises a sound control power off switch operable by a user blowing air toward the imitation flame body. Further, a fragrance box may also be provided inside the housing.
"The beneficial effects of the present invention would be generally understood and appreciated in the detailed description of the embodiments below."
