The specific implementation process of the foot warming platform disclosed by the embodiment is as follows:

the teacher does blackboard writing from the left side to the right side in the teaching process, so the teacher firstly stands on the left side part to give lessons, the teacher steps on the pedal 105 above the leftmost heating space 104, the spring 114 is compressed due to the self weight of the teacher, the pedal 105 moves downwards and touches the limit switch 209, the upper support 113 and the lower support 112 are of a sleeve type structure, and the pedal 105 can be ensured to move vertically and vertically without deviation. When the pedal 105 touches the limit switch 209, it contacts the limit base 208, and thus stops moving downward. As the pedal 105 moves downwards for a certain distance, the sliding block 108 moves leftwards along the light bar 107 by the conduction of the pressing connecting rod 111, and then the inclined plate 106 deflects downwards by taking the hinge as an axis by the conduction of the pulling connecting rod 110, so that an inclined plane is formed between the pedal 105 and the platform board 101, and the problem that the teacher stumbles over due to the step formed between the pedal 105 and the platform board 101 because the pedal 105 is lowered is avoided. The inclined plates 106 on the two sides run in the same track, and the difference is that the inclined plates 106 are located on the right side, the slide block 108 slides towards the right side relative to the light bar 107, the right side is also connected with a ventilation connecting rod 305, the ventilation connecting rod 305 conducts the ventilation connecting rod 305, so that the ventilation plate 303 moves upwards, and the second ventilation holes 304 in the ventilation plate 303 after moving are communicated with the third ventilation holes 302 in the pressing plate 301 and the first ventilation holes 103 in the separation plate 102. At this time, the controller 4 controls the electric fan 201 to be turned on, the resistance wire 207 is controlled to be heated, the wind blown by the electric fan 201 blows over the baffle 202 due to the height of the electric fan 201, the hot air heated by the resistance wire 207 rises, the cold air sinks, and after the wind blown by the electric fan 201 blows, the hot air forms clockwise flow in the corresponding heating space 104, namely the hot air flows clockwise from the upper side of the baffle 202 and flows back from the backflow hole 204 of the vertical plate 203 on the lower side of the baffle 202, and the above operation is repeated. Meanwhile, part of the hot air enters the next heating space 104 through the pressing plate 301, the ventilation plate 303 and the partition plate 102 to preheat the next heating space 104, so that the thermal interruption caused by insufficient temperature of the next heating space 104 in the initial heating stage when a teacher moves from the left heating space 104 to the next heating space 104 is avoided.

When the teacher moves from the left heating space 104 to the middle heating space 104, the pedal 105 of the left heating space 104 is restored to the initial position under the action of the spring 114, at this time, the pedal 105 leaves the limit switch 209, the electric fan 201 of the left heating space 104 stops rotating, the resistance wire 207 stops heating, the light bar 107 is restored to the original position, and the inclined plate 106 is restored to the original position and is flush with the pedal 105. The middle heating space 104 is now performed in the same step as the left heating space 104.

When the teacher moves from the middle heating space 104 to the right heating space 104, the right heating space 104 is implemented in the same steps as the middle heating space 104, and the right heating space 104 is implemented in the same steps as the left heating space 104, except that the preheating adjusting unit 3 is not provided at the end of the heating space 104 and the back is not preheated.
