For example: the outlet 90 may be an opening formed in the panel 92. Of course, it is also possible to reduce the length of the panel 92 so as to expose an opening in the heater casing 91. In other words, the air outlet 90 and the panel 92 are located on the same side of the warm air casing 91, and the air outlet 90 is located immediately adjacent to an edge of the panel 92.
In an embodiment, the air heating device 9 further comprises a cover trajectory control structure 93.
The detailed structure of the air heating device 9 will be described in more detail below.
The automatic cover plate structure 1 and the cover plate track control structure 93 are arranged in the warm air shell 91 and are carried or loaded by the warm air shell 91. Of course, other structures or components, such as a heater, a sensor, a controller, etc., may be disposed in the warm air casing 91. The panel 92 is installed at one side of the warm air housing 91, and is used to enclose the warm air housing 91 and shield or protect all structures or components inside the warm air housing 91. The air outlet 90 and the panel 92 are located on the same side of the warm air casing 91, and the air outlet 90 is located at one edge of the panel 92 and is adjacent to the edge 920 of the panel 92. In addition, the air heating device 9 further includes an air inlet 94, as shown in fig. 4. The air inlet 94 is located at the other edge of the panel 92. Therefore, the air inlet 94 and the air outlet 90 are disposed opposite to each other.

As shown in fig. 4, when the automatic cover plate structure 1 opens the air outlet 90, the cover plate 10 is hidden in the warm air casing 91, so as to realize a hiding function.
As described above, the cover trajectory control structure 93 is provided inside the air heater 9, the cover 10 is provided with the sliding structure 11, and the sliding structure 11 is connected to the cover trajectory control structure 93, so that the cover 10 can move according to a predetermined movement trajectory in the reciprocating motion.
In one embodiment, the sliding structure 11 is a protruding structure protruding from two opposite ends of the cover plate 10; the track control structure is a track which is arranged on the warm air shell 91 and is positioned at two sides of the air outlet 90; the raised structure can enter the track to define the motion trajectory of the cover plate 10 in the reciprocating motion.
The cover trajectory control structure 93 can be seen with particular reference to fig. 3a, the cover trajectory control structure 93 (i.e. the track) has at least one inclined section 931 near the outlet 90 and a straight section 932 far away from the outlet 90, wherein the straight section 932 is proximate to the bottom of the warm air casing 91 (where the term "proximate" includes the case where the straight section 932 is the bottom of the warm air casing 91), and a free end 9310 of the inclined section 931 extends toward the outlet 90 (or extends upward). The cover trajectory control structure 93 (i.e., the track) also has a fixed inflection point 933 located between the inclined section 931 and the straight section 932, the fixed inflection point 933 having a height that is substantially flush with a height of the free end 9310 of the inclined section 931.
When the cover plate 10 is in the closed state, as shown in fig. 3b, the first leg 110 of the sliding structure 11 is located at the free end 9310 of the inclined section 931, and the second leg 112 is snapped into the fixed inflection point 933, so as to provide a stabilizing effect for the automatic cover plate structure 1.
When it is required to open the air outlet 90, as shown in fig. 3c, the cover plate 10 is retracted backward under the control of the linear actuator 20 and the driving mechanism 30, the first leg 110 descends along the inclined section 931, the second leg 112 disengages from the fixed inflection point 933, and finally both the first leg 110 and the second leg 112 enter the straight section 932, and the cover plate 10 descends to the bottom position of the warm air casing 91.
It can be seen that the cover plate 10 is adjusted in position up and down along the predetermined movement track provided by the track by the design of the cover plate track control structure 93, which is more favorable for discharging hot air. When the cover plate 10 is retracted to the bottom of the warm air casing 91, a smooth flow channel can be provided for the hot air, the output of the hot air is not obstructed, and therefore the air outlet effect of the air heating device 9 is improved.
When the air heating device 9 does not work, the stepping motor drives the rack 24 to move forward, the cover plate 10 is pulled by the connecting piece 40, the sliding piece of the cover plate 10 is driven forward on the track, the cover plate 10 moves forward and rises to be on the same plane with the panel 92, the air outlet 90 is shielded by the cover plate 10 of the automatic cover plate structure 1, and therefore dust and mosquitoes are prevented from entering the air heating device 9, and the air heating device 9 is prevented from short-circuit fire.
In summary, the cover plate 10 of the automatic cover plate structure 1 provided by the present invention can open and close the air outlet 90 of the air heating device 9 under the control of the linear transmission mechanism 20 and the driving mechanism 30. When the air heating device 9 works, the cover plate 10 can retreat in the warm air shell 91 away from the air outlet 90 according to a preset track and gradually hide in the warm air shell 91 of the air heating device 9, so that the air outlet 90 is opened for blowing air; when the air heating device 9 does not work, the cover plate 10 can move towards the air outlet 90 in the air heating shell 91 according to a preset track and shield the air outlet 90, so that dust and mosquitoes can be prevented from entering the air heating device 9, and the short-circuit fire of the air heating device 9 is avoided.
