(19) A conventional candle or aroma diffuser generally includes a wax block and a wick embedded in the wax block, where the wick transports wax oil to sustain combustion, which achieves illumination or fragrance release. The conventional candle or aroma diffuser usually has defects such as inconvenient ignition, unstable placement, and lower safety. With technological advancements, some electronic candle holders that are electronically ignited have emerged in the market. An electronic candle holder mainly includes a holder, a wax block placed inside the holder, and a wick inside the wax block, where the wax block contains essential oils for emitting fragrance. Before use, a candle is placed in a desired position and ignited, and the holder is placed stably, which prevents melted wax from spilling out during combustion and protects the wax block to some extent.

That is, air from the fan 12 flows through the air duct 24 and is blown towards the combustible wick 33 from the air guide vent 201.

(26) In this example, the air duct 24 is of an annular cavity structure formed between the light-transmitting cup 2 and the container cup 31, which simplifies the structural design without need of a separately designed air duct. To extinguish the combustible wick 33 of the combustion assembly 3, the fan 12 is controlled to start blowing air towards the combustible wick 33 of the combustion assembly 3, and then the combustible wick 33 is extinguished. Compared to the prior art, the electronic combustion device 100 in this example extinguishes the combustion assembly 3 through the fan 12, and compared to manual extinguishing by the user with his/her mouth, automatic extinguishing of the combustible wick 33 is achieved, which offers a better and safer user experience.

When the user presses the switch button again, the control circuit board 15 controls the fan 12 to blow air towards the combustible wick 33, so as to extinguish the combustible wick 33. The duration setting button is configured for the user to input an operational duration of starting the electronic combustion device 100, the operational duration in hours or minutes may be preset based on actual needs, and upon expiry of the preset operational duration, the fan 12 is controlled to start extinguishing the combustible wick 33.
