One example, electronic candle device includes a housing with a through-hole at its top, a transfer device including a driver motor and one or more gears positioned inside the housing, and a light emitting component coupled to the transfer device such that the transfer device causes the light emitting component to move vertically up or down to protrude from the housing or to retract into the housing. The electronic candle also includes a movable lid positioned below the through-hole inside the housing and movable to remain in at least one of an open configuration or a closed configuration, and a controller configured to turn on or off the light emitting component. ## Claims ### Claim 1 An electronic candle, comprising: a housing having a through-hole; one or more gears positioned inside the housing; a motor configured to drive the one or more gears; a light emitting component coupled to the one or more gears configured to move vertically up or down to protrude from the housing or to retract into the housing; a movable lid positioned inside the housing and movable to remain in at least one of an open configuration or a closed configuration, the movable lid comprising two top sections, each top section configured to come together to substantially close the through-hole in the closed configuration and move away from one another to allow at least a section of the light emitting component protrude from the housing in the open configuration. ### Claim 2 (depends on 1) The electronic candle of claim 1, further comprising: a rack that is configured to engage the one or more gears and to move within the housing to cause the light emitting component to move up or down within the housing. ### Claim 3 (depends on 2) The electronic candle of claim 2, wherein the one or more gears comprises: a first gear coupled to the motor; and a second gear engaged with the first gear and the rack, wherein the second gear is a bigger diameter than the first gear. ### Claim 4 (depends on 1) The electronic candle of claim 1, further comprising: a wick component coupled to the movable lid, wherein the wick component is configured to retract into the housing in the open configuration and to protrude from the housing in the closed configuration. ### Claim 5 (depends on 4) The electronic candle of claim 4, wherein the wick component comprises: a dark section resembling a wick of a used candle, and a first spring coupled to the wick and the movable lid, the first spring configured to accumulate energy when the movable lid is in the open configuration and release the accumulated energy upon the movable lid transitioning to the closed configuration. ### Claim 6 (depends on 1) The electronic candle of claim 1, comprising: a switch coupled to the movable lid to trigger the closing or opening of the movable lid. ### Claim 7 (depends on 1) The electronic candle of claim 1, comprising a spring coupled the movable lid and the housing configured to accumulate energy in case the movable lid is in the open configuration and release the accumulated energy in case the movable lid transitions to the closed configuration. ### Claim 8 (depends on 1) The electronic candle of claim 1, wherein the movable lid includes two bottom sections configured to move sideways to allow the light emitting component to move up within the housing. ### Claim 9 (depends on 8) The electronic candle of claim 8, wherein the two bottom sections of the movable lid form a channel within which the light emitting component is positioned, and wherein, upon the light emitting component protruding from the housing, the two top sections are configured to slide within the housing to open the through-hole due to a force applied thereto by the movement of the light emitting component. ### Claim 10 (depends on 8) The electronic candle of claim 8, wherein each of the bottom sections of the movable lid is configured to slide against a housing of the light emitting components as the light emitting component moves upward or downward within the electronic candle housing. ### Claim 11 (depends on 8) The electronic candle of claim 8, wherein each of the bottom sections includes a side that is formed at a slanted angle with respect to the housing of the candle device. ### Claim 12 (depends on 1) The electronic candle of claim 1, wherein the two top sections form an opening in the closed configuration to allow a wick to protrude upward from the opening. ### Claim 13 (depends on 1) The electronic candle of claim 1, wherein the light emitting component includes a flame sheet that resembles a real candle flame. ### Claim 14 (depends on 13) The electronic candle of claim 13, wherein the light emitting component includes one or more light sources to illuminate the flame sheet. ### Claim 15 (depends on 1) The electronic candle of claim 1, further comprising: a controller configured to turn on or off the light emitting component. ### Claim 16 (depends on 15) The electronic candle of claim 15, further comprising: a sensor positioned inside the housing and coupled to the controller, the sensor configured to receive an external input and convert the received external input into an electrical signal, wherein an operation of the electronic candle is controlled in response to the electrical signal. ### Claim 17 (depends on 16) The electronic candle of claim 16, wherein the sensor is positioned inside an installation slot on a base on the light emitting component. ### Claim 18 (depends on 1) The electronic candle of claim 1, wherein the light emitting component includes a flame element and at least one light source that is configured to project light onto the flame element upon protrusion of the flame element from the housing, and to turn off the projected light when the flame element is not protruding from the housing. ### Claim 19 (depends on 1) The electronic candle of claim 1, further comprising: a battery; and a recharging dock that is shaped as a candle holder and configured to recharge the battery.
