Of course, the present invention also preferably includes an inner ring 411 and an outer ring 412. Double-supported beam arm The high-temperature resistant plate 42 has three side edges which are inserted into the corresponding slots I4131 and II41a, respectively, and extends from the same side of the slots I4131 and II41a.

[0023] The first heat generating device 43-1 and the second heat generating device 43-2 in this embodiment employ a spring structure, and are fixedly attached to the high-temperature resistant plate 42. A plurality of through holes 42a are formed in the high-temperature resistant plate 42. The through holes 42a are Double-supported beam arm The first heating device 43-1 and the second heating device 43-2 are fixedly attached with a vertical offset from each other, and the first heating device 43-1 and the second heating device 43-2 form a heating structure with multiple concentric rings that do not overlap when projected onto the axial plane of the heating bracket 41.

[0024] In the embodiment, four heating devices 43 are provided, which are distinguished by the size of the enclosed radius and numbered sequentially as 1#, 2#, 3#, 4#, and the 1# heating device is connected in series with the 3# heating device at its head and tail, and the 2# heating device is connected in series with the 4# heating device at its head and tail.

[0027] When the motor is operating, the fan blades are driven to rotate at high speed, generating negative pressure inside the frame, driving the air to be sucked in through the air inlet, and the air enters the air duct, passes through the heating element and the fan blades, and is blown out through the air outlet. When the heating element is operating, warm air can be produced, and when the heating element is not operating, cool air can be produced.

[0028] Of course, the number of high-temperature resistant plates 42 can be set according to the specific situation, and the heat generating devices 43 interposed between the high-temperature resistant plates 42 are not limited to the number mentioned in the above embodiment, nor are they limited to the series connection shown in the figure, but can of course be connected in parallel with each other, and for multiple groups of heat generating devices, a combination of series connection and parallel connection can also be adopted, and detailed explanations will not be repeated.

[0030] The present invention is applicable to the prior art to the extent not mentioned above.
