Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to an improved cold and warm mist humidifier. Background Art

[0002] Chinese patent document No. CN211060306U disclosed a cold and warm mist humidifier on July 21, 2020, including a base and a water tank installed above the base, a water mist generating groove connected to the water tank is provided on the base, and a water mist exhaust pipe connected to the water mist generating groove is provided on the water tank. A water mist generator and an electric heating device are installed at the bottom of the water mist generating groove, and a cold and hot water insulation seat is installed in the water mist generating groove. The cold and hot water insulation seat is arranged around the outer periphery of the electric heating device. The cold and hot water insulation seat and the electric heating device constitute a heating evaporation chamber, and a unidirectional water replenishment channel is opened on the cold and hot water insulation seat, and the heating evaporation chamber is connected to the water mist generating groove through the water replenishment channel. The cold and warm mist humidifier generates cold mist in the cold mist chamber through a water mist generator, and the cold mist enters the mist exhaust pipe. The clean water in the heating evaporation chamber is heated into hot mist through an electric heating device. The hot mist enters the mist exhaust pipe and is discharged after mixing with the cold mist. The temperature of the discharged mist will not be too high to prevent scalding. However, the mist exhaust pipe is connected to the heating evaporation chamber through an inclined mist guide hood. The hot mist has a long travel through the mist guide hood, and the inclined mist guide hood will reduce the flow speed of the hot mist, so that a part of the hot mist will condense into water in the mist guide hood and reflux. This will reduce the mist outlet efficiency of the humidifier, and the mist outlet temperature will be too low, resulting in poor mist outlet effect.

[0003] Therefore, further improvements are necessary. Utility Model Content
