The extending motion of the electric push rod 5 and the opening and closing motion of the opening and closing type ceiling system 7 are synchronously linked through the main motor 1, no error occurs in matching, and the integral driving structure is simplified.
In the whole working process, the opening-closing type ceiling system 7 is opened firstly along with the positive rotation of the main motor 1, meanwhile, the electric push rod 5 extends downwards, the opening-closing type ceiling system 7 starts to be closed again until the opening-closing type ceiling system 7 is completely opened, the electric push rod 5 extends to protrude below the opening-closing type ceiling system 7, and the main motor 1 stops rotating until the opening-closing type ceiling system 7 is matched with a rod body of the electric push rod 5 to be contacted and sealed, so that the extending process of the fan 6 is completed. The fan 6 can then operate by itself to generate cool air. When the fan 6 is turned off, the main motor 1 is reversed to retract the electric ram 5 again, and the fan 6 is housed inside the open/close type ceiling system 7.
Preferably, the inner ends of the blades of the fan 6 are elastically hinged to the fan motor in a normally closed manner, so that the blades are normally folded in a normally closed manner by the elastic force and are radially outwardly extended by the centrifugal force generated by the rotation of the fan motor.
Referring to fig. 2 to 4, preferably, the retractable ceiling system 7 includes a frame 8 surrounding the periphery, two ceiling blocks 9 split and connected in opposite directions, and a transmission mechanism installed above the ceiling blocks 9; the transmission mechanism comprises a secondary belt wheel 10, a belt transmission assembly, a transmission component 11, a sliding component 12, a connecting rod 13, a linear guide rail 14, a sliding block 15 and a swing rod 16; the secondary belt wheel 10 is in transmission connection with the primary belt wheel 4 through a first transmission belt 19; the belt transmission component is vertically arranged above the ceiling block 9 and is positioned in the middle of the front side and the rear side of the frame 8; the belt transmission component comprises two transmission belt wheels 17 and a second transmission belt 18 wound on the two transmission belt wheels 17, wherein one transmission belt wheel 17 is in transmission connection with the secondary belt wheel 10; one end of the transmission member 11 is provided with a connecting end, the other end of the transmission member 11 is provided with a pin hole, and the connecting end of the transmission member 11 is connected with a second transmission belt 18; the sliding component 12 is connected above the middle part of the front side and the rear side of the frame 8 in a sliding manner along the vertical direction, the middle part of the sliding component 12 is rotationally connected with the pin hole of the transmission component 11 through a pin shaft, and the left side and the right side of the sliding component 12 are provided with connecting arms; the upper end of the connecting rod 13 is hinged with the connecting arm, and the lower end of the connecting rod 13 is hinged with the ceiling block 9; the front side and the rear side of the ceiling 9 are transversely and fixedly provided with linear guide rails 14, and the linear guide rails 14 are connected with sliding blocks 15 in a sliding manner; two swing rods 16 which are arranged in parallel are arranged on each sliding block 15, one end of each swing rod 16 is hinged with the corresponding sliding block 15, and the other end of each swing rod 16 is hinged with the front side and the rear side of each frame 8.
The operation of the main motor 1 drives the operation of the main belt pulley 4, and the main belt pulley 4 drives the auxiliary belt pulley 10 through the first transmission belt 19, so as to drive the belt transmission assembly to operate. The second belt 18, during operation, moves the drive member 11 connected thereto. Because the second belt 18 is formed by two straight line segments and two arc segments, the motion of the transmission member 11 changes the motion direction as an inflection point at the two arc segments, and the two straight line segments respectively perform reverse linear lifting motion. The lifting motion of the transmission member 11 drives the sliding member 12 to lift along the vertical direction, so that the connecting rod 13 is driven to reciprocate to push and pull the ceiling block 9, and the ceiling block 9 is opened and closed. The opening and closing of the ceiling 9 is stably performed by the lateral sliding connection between the linear guide 14 and the slider 15. Meanwhile, at the initial stage of the opening action and the end of the closing action, the swing rod 16 can drive the ceiling block 9 and the frame 8 to be dislocated or reset, so that the interference between the ceiling block and the frame 8 in the opening process is avoided.
Preferably, a spring (not shown) is arranged between the swing rod 16 and the front side and the rear side of the frame 8, so that the swing rod 16 tends to swing towards the direction of opening the ceiling 9, and therefore, in the initial stage of the opening movement of the ceiling 9, the swing rod 16 swings under the action of the spring to drive the ceiling 9 to be staggered with the frame 8; at the end of the closing movement of the ceiling block 9, the connecting rod 13 pulls the ceiling block 9 to overcome the elastic force of the spring, so that the swing rod 16 drives the ceiling block 9 to be flush with the frame 8 again. It should be noted that the above-mentioned effect can also be achieved by the effect of the ceiling 9 due to its own weight, and whether or not a spring is mounted is not an essential feature.
Referring to fig. 5, preferably, the driving pulley 17 is provided with a missing tooth 21, and the connecting end of the driving member 11 is provided with a connecting tooth matched with the missing tooth 21, so that the connecting tooth is engaged with the missing tooth 21 when the driving member 11 passes through the driving pulley 17. The position of the missing tooth 21 is calculated and corresponds to the movement period of the transmission member 11, and every time the transmission member 11 turns around through the belt wheel, the connecting tooth is meshed with the missing tooth 21, so that the connecting part of the transmission member 11 is prevented from being interfered and locked with the belt wheel. In addition, the pin hole of the transmission member 11 should reciprocate up and down on a vertical line, so that the distance from the pin hole of the transmission member 11 to the connecting end is preferably equal to the radius of the transmission pulley 17, so that the pin hole does not swing to the left or right when the transmission member 11 passes through a pulley turn, thereby ensuring the connection with the sliding member 12.
Referring to fig. 2 to 4 in detail, the sliding member 12 is preferably slidably connected to the upper portion of the middle portion of the front and rear sides of the frame 8 by vertically-arranged guide rods 20.
Preferably, the left side and the right side of the frame 8 are respectively provided with a frame 8 inclined plane which is inclined upwards and converged; the opening side of the ceiling block 9 is correspondingly provided with a ceiling inclined plane which is matched with the inclined plane of the frame 8 and is inclined upwards for convergence, so that the ceiling inclined plane is close to the inclined plane of the frame 8 when the ceiling block 9 is completely closed.
When the swing rod 16 swings to drive the ceiling block 9 to be dislocated with the frame 8 downwards, the movement rule is a swinging arc line. Therefore, the left and right sides of the frame 8 are inclined surfaces of the frame 8 which are inclined upwards and converged to match the motion track.
Referring to fig. 6 to 7, preferably, the closed side of the ceiling 9 is provided with a convex portion 22 protruding toward the closing direction and a concave portion 23 recessed toward the opening direction, the convex portion 22 and the concave portion 23 are matched with each other and respectively occupy half of the closed side of the ceiling 9, and the convex portions 22 and the concave portions 23 of the two ceiling 9 are arranged in a central symmetry manner, so that the convex portion 22 of any one ceiling 9 and the concave portion 23 of another ceiling 9 are engaged with each other when the two ceiling halves are completely closed. Furthermore, the convex part 22 and the concave part 23 of the same ceiling block 9 are transited by a first bevel edge 25; an inner shielding plate 24 protruding towards the closing direction is fixedly arranged above the concave part 23, and a second bevel edge 26 which is mirror-symmetrical to the first bevel edge 25 is arranged on one side of the inner shielding plate 24 close to the first bevel edge 25; when the two ceiling tiles 9 are completely closed, the inner shielding plate 24 is closed above the convex portion 22 of the other ceiling tile 9; when two ceiling tiles 9 are gapped, the two first oblique edges 25 and the two second oblique edges 26 enclose a central hole 27 in the centre of the closing line of the ceiling tiles 9.
The unique design of the ceiling 9 allows the ceiling 9 to be completely closed without leaving a central opening 27 in the center for the equipment above to run down and be exposed below the ceiling 9 after the ceiling 9 is opened, and allows room for the equipment to be lifted when the ceiling 9 is closed. The ceiling tile 9 is now not completely closed, but the shading action is substantially completed.
More preferably, an electrical switch (not shown) is attached above the first inclined side 25 or the second inclined side 26, and the electrical switch is electrically connected to the main motor 1. The shaft of the extended electric putter 5 can be sensed through the electric switch, thereby generating a sensing signal to stop the main motor 1.

The splicing structure is formed by two butted ceiling blocks 9, and reciprocating opening and closing actions can be realized under the driving of the transmission mechanism. The transmission mechanism has simple structure, stable and reliable use, low cost and low noise and is driven by a belt to carry out linkage. The structure of the ceiling half-plate can form a central hole 27 in a state of leaving a gap, so that the ceiling half-plate can be closed and shielded in a state of extending the electric push rod 5 by being convenient to match the extending action of the electric push rod 5.
