Wax melting device

A wax melting device comprises a heat supply module, a control module, a shade module and a fixing piece. Wherein the heat supply module comprises a plurality of heating units, the control module is electrically connected to the plurality of heating units and can independently regulate and control the plurality of heating units to heat corresponding candles, and the shielding module is fixedly arranged outside the heat supply module in a covering manner and is used for partially shielding the plurality of heating units. And the heat energy of each heating unit is more intensively stored in the corresponding candle position, so that excessive energy consumption caused by invalid dissipation of a heat source is avoided. Therefore, the fragrance volatilization intensity of different positions can be adjusted according to the requirements of a user during operation, or various single fragrances can be automatically mixed and matched to form special fragrance, the inconvenience of repeated replacement and taking c
