In one embodiment, the shape of the air outlet 430 is one or a mixture of several of a strip, a circle, or a polygon. The shape of the outlet 430 may be designed according to actual design requirements.

Please refer to fig. 7, which is a schematic structural diagram illustrating a connection between a warm air structure 200 and a shift switch button 130 according to an embodiment of the present application. The warm air structure 200 includes: a heating unit 210, a fan 220, and a power supply 230. The fan 220 is disposed above the heating unit 210. In one embodiment, the fan 220 and the heating unit 210 can be connected by a bolt fastening method. The power supply 230 may be a battery, and the power supply 230 is connected to the fan 220 and the heating unit 210 through a wire. In an embodiment, a plug with three plugs may be connected to the fan 220 and the heating unit 210 through a wire, and the three plugs are connected to a plug board to power the fan 220 and the heating unit 210.

In this embodiment, the fan 220 is an axial fan. The working principle of the axial flow fan is as follows: the gas axially enters the rotating blade channel, is pressurized and then is axially discharged from the other surface.

The housing 100 is further provided with a window 120, a gear shift button 130 (see fig. 3) is mounted on the window 120, and the gear shift button 130 is connected to the fan 220 through a wire.

When a user uses the warm air device 12, the power supply 230 supplies power to the heating unit 210 and the fan 220, the heating unit 210 generates heat to generate heat, the fan 220 rotates, air is axially sucked into a rotating blade channel of the fan 220 from an air inlet 310 on the air plate 300, the air is heated and pressurized to form warm air, and the warm air is axially discharged from the other side of the fan 220 and is discharged from an air outlet 430 on the bottom plate 400.

Because the wind deflector 410 is conical like a hill, warm air flows along the arc-shaped edge of the raised part 440 of the wind deflector 410, and the moving direction of the warm air is changed by the guidance of the raised part 440, so that the wind deflector 410 guides the warm air to the bottom plate 400, and the warm air is uniformly blown out through the plurality of air outlets 430 on the bottom plate 400 (see fig. 5 and 6), so that the warm air is uniformly dispersed all around, and people sitting on the periphery of the mahjong table 1 can be warmed.

By adjusting the range switch button 130, different operating frequencies of the fan 220 can be selected. The rotation of the fan 220 with different frequencies can control the heat of the warm air. The higher the operating frequency of the fan 220, the faster the fan 220 is rotated, and the more warm air is generated. In one embodiment, the fan 220 with two adjustable operating frequencies, i.e., low frequency (300W)/high frequency (600W), is provided by the gearshift button 130. The user can toggle the gear shift button 130 to switch the operating frequency of the fan 220 according to the heating requirement.

In one embodiment, the heating unit 210 may be a PTC heater. The working principle of the PTC heater is as follows: when the PCT heating plate is electrified, the resistance value is increased to enter the jump zone by self-heating, and the surface temperature of the PTC heating plate is kept constant, wherein the surface temperature is only related to the Curie temperature and the applied voltage of the PTC heating plate and is not basically related to the ambient temperature. When the fan 220 stops due to a fault, the power of the PTC heater is automatically and rapidly reduced because the PTC heater cannot sufficiently dissipate heat, and the surface temperature of the PTC heater is maintained at about the Curie temperature (generally about 250 ℃), so that the surface of the heater such as an electric heating pipe heater does not turn red.

It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
