The outer side surface of the heater shell corresponding to the air outlet cavity is attached to the inner wall of the fan air outlet shell to form sealing, namely, the air flow of the fan air outlet shell can only be blown out through the heater, so that the warm air effect is improved; and compact structure occupies little space inside the fan air-out casing, and is convenient for arrangement and installation.

The outlet of the fan heater is positioned in the air outlet of the fan air outlet shell; preferably, the air outlet protrusion of the fan heater is clamped in the air outlet of the fan air outlet shell, and the fan heater is compact in structure, stable and reliable.

A gap is formed between the outer side face of the heater shell corresponding to the heating cavity and the inner wall of the fan air outlet shell, the fan air outlet shell is prevented from being directly contacted with the heater, the outer shell is prevented from being deformed due to overhigh temperature, and the structural stability is improved. If the fan is required to blow natural wind, the heater does not work, and the bladeless fan with the cooling function and the heating function is formed.

The heater shell is connected with the inner wall of the fan air outlet shell through a clamping structure, so that the installation and the fixation are convenient; and a guide groove structure is arranged between the heater shell and the inner wall of the fan air outlet shell, so that the installation is simple and convenient, and the structure is stable and reliable.

Preferably, a positioning clip is arranged on the outer side surface of the heater shell, and a limiting clip matched with the positioning clip 1403 is arranged on the inner wall of the fan air outlet shell; and be equipped with conducting bar 304 on heater casing's an outside face, be equipped with the guide slot with conducting bar looks adaptation on the inner wall of fan air-out casing, be equipped with constant head tank 1405 on the other outside face of heater casing, be equipped with the baffle with the constant head tank looks adaptation on the fan air-out casing inner wall, fix a position through the guide slot structure, it is simple and convenient to assemble, reliable and stable. And a set of side ribs 306 are provided on the outer surface of the heater housing to form a support for the fan outlet housing.

The fan air-out casing includes air-out circle front side casing 303 and air-out circle back side casing 304 that link to each other, forms the fan between air-out circle front side casing and the air-out circle back side casing and bloies the cavity, and the air outlet is established on air-out circle front side casing, and the heater is established in air-out circle front side casing, the installation of the fan heater of being convenient for.

Because the heater is only positioned in the front shell of the air outlet ring, the air outlet shell of the fan forms a large enough air cavity, and the heating and warm air effect is improved.

The air outlet of the annular air outlet ring blows out warm air, the space inside the annular air outlet ring forms air flow, and the water mist blown out of the water mist outlet is in the front of the space inside the annular air outlet ring, so that warm air flow with certain humidity is formed, the dry warm air effect is not easy to occur, and the warm air quality of the fan is improved.

The above-mentioned features are merely for describing preferred embodiments of the present invention and may be arbitrarily combined to form a plurality of embodiments of the present invention.

The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution, or to apply the inventive concept and solution directly to other applications without modification.
