The cover plate 2 is arranged by adopting a rotatable structure, the air inlet position and the air outlet position are respectively limited on two opposite sides of the shell structure, the cover plate 2 inclines relative to the shell body 1, a certain guiding effect can be achieved on air inlet, the air suction condition from the air outlet side is reduced, and air return is well avoided.
Specifically, the cover plate 2 has an initial position connected with the housing main body 1 to seal the air inlet 13 and a transition position spaced from the housing main body 1; when the cover plate 2 is in the transition position, a movable gap exists between the first end and the second end of the cover plate 2 and the shell main body 1 so as to avoid the rotation of the cover plate 2. By enabling the cover plate 2 to have an initial position and a transition position, when the cover plate 2 is at the initial position, the air inlet 13 can be blocked, so that dust is prevented from entering the shell main body 1 when the cover plate is not used, and the shell structure is more attractive; when apron 2 is in the transition position, can provide rotatory space for apron 2, guarantee that apron 2 rotates smoothly.
Specifically, the panel structure includes: and a rotation driving part 4, wherein the rotation driving part 4 is connected with the cover plate 2, so that the cover plate 2 is driven to rotate by the rotation driving part 4.
As shown in fig. 2, the rotation driving section 4 includes: a first rotation driving source 41, an output shaft of the first rotation driving source 41 having a first preset rotation angle and a second preset rotation angle; a buffer 42, through which the output shaft of the first rotation drive source 41 is connected to the cover 2; when the output shaft of the first rotary driving source 41 is at a first preset rotation angle, the cover plate 2 rotates to a first air inlet position; when the output shaft of the first rotary driving source 41 is at a second preset rotation angle, the cover plate 2 rotates to a second air inlet position; when the rotation angle of the output shaft of the first rotation driving source 41 exceeds the first predetermined rotation angle or the second predetermined rotation angle, the buffer member 42 deforms, so that the cover plate 2 is maintained at the first air inlet position or the second air inlet position. Since it is difficult for the first rotary driving source 41 to ensure high repeated positioning accuracy after repeated operation for a long time, by providing the buffer member 42, the cover plate 2 can be maintained at the first air inlet position or the second air inlet position even when the rotation angle of the output shaft of the first rotary driving source 41 exceeds the first predetermined rotation angle or the second predetermined rotation angle. The stability of the long-time repeated operation of the rotation driving portion 4 is ensured.
According to practical requirements, the following arrangement of the buffer member 42 can be adopted:
in a first arrangement, the buffer member 42 includes at least three strip members hinged in sequence, and at least two strip members of the buffer member 42 are connected to the cover plate 2 so as to deform the buffer member 42 through relative rotation between the strip members. By using the bars connected in sequence, it is possible to make the buffer member 42 deformed when relatively rotating between the bars to maintain the position of the cap plate 2.
As shown in fig. 2, the buffer member 42 includes a first bar 421, a second bar 422, and a third bar 423, wherein a middle portion of the first bar 421 is connected to the output shaft of the first rotary drive source 41, one end of the first bar 421 is rotatably connected to a first end of the second bar 422, the other end of the first bar 421 is rotatably connected to a first end of the third bar 423, a second end of the second bar 422 is rotatably connected to the cover plate 2, and a second end of the third bar 423 is rotatably connected to the cover plate 2; the force that deforms the buffer 42 is greater than the weight of the cover plate 2. By compressing the connected strips together, the purpose of the deformation force being greater than gravity is achieved by friction between the individual strips of the buffer 42. The first strip 421, the second strip 422, the third strip 423 and the structure between two hinge points on the cover plate 2 together form a quadrilateral structure, and when the adjacent strips rotate relatively, the quadrilateral structure deforms, so that the buffer member 42 deforms to maintain the position of the cover plate 2.
Preferably, the length of the second strip 422 is equal to the length of the third strip 423, and the distance between the hinge point of the second strip 422 and the cover plate 2 and the hinge point of the third strip 423 and the cover plate 2 is equal to the length of the first strip 421. In this way, when the first bar 421, the second bar 422, the third bar 423 and the structure between the two hinge points on the cover plate 2 together form a parallelogram structure, the inclination angle of the cover plate 2 is always the same as that of the first bar 421, so as to facilitate the control of the inclination angle of the cover plate 2.
In the second arrangement, the buffer member 42 is an elastic member, a first end of the elastic member is connected to the output shaft of the first rotary driving source 41, and a second end of the elastic member is connected to the cover plate 2, so that the cover plate 2 is maintained at the first air inlet position or the second air inlet position by elastically deforming the elastic member.

Preferably, the buffer member 42 is a spring, a first end of which is connected to the output shaft of the first rotary drive source 41, and a second end of which is connected to the cover plate 2. When the rotation angle of the output shaft of the first rotation driving source 41 exceeds the first predetermined rotation angle or the second predetermined rotation angle, the spring is bent, so that the cover plate 2 is maintained at the first air inlet position or the second air inlet position. Thus, the buffer function is realized with a simple structure, and the stability of the long-time repeated operation of the rotation driving part 4 is ensured.
