[0019] Compared with the prior art, the present invention provides a cold and heat exchange box EC fan, which has the following beneficial effects:

[0020] 1. The heat exchange box EC fan pushes the disc to move through the first electric push rod, so that the disc drives the connecting column to move through the rotating shaft, so that the connecting column drives the gear ring to separate from the first gear. At this time, the gear ring is engaged with the first gear, and by continuously pushing the rotating shaft, the rotating shaft controls the first ball to drive the gear ring to rotate through the spiral groove. At this time, the gear ring can be transmitted with the first gear, so that the first gear can drive the blade shaft to rotate, and the blade shaft can drive the blade to rotate, so that the angle of the blade can be adjusted, so that the air intake volume can be adjusted by adjusting the blade angle, which meets the actual use needs and can be applied in different situations.

[0021] 2. The EC fan of the cold and heat exchange box drives the second ball to move through the second electric push rod, so that the second ball enters the special-shaped groove. Since the special-shaped groove is arranged in a continuous V-shape, the second ball can drive the rotating drum to realize reciprocating rotation, and the rotating drum drives the conveying structure to reciprocate. Under the transmission of the two second gears, the two conveying structures move synchronously, and the conveying structure can drive the cleaning cloth to reciprocate. Since the blade is located between the two cleaning cloths, the cleaning cloth can smoothly clean the blade, thereby reducing the difficulty of cleaning the blade and avoiding the problem of easy injury during manual cleaning.

[0022] 3. The EC fan of the cold and heat exchange box body pushes the disc to move through the first electric push rod, so that the gear ring is meshed with the first gear. At this time, the gear ring is driven by the first gear by continuous pushing, and the blade shaft drives the blade to rotate. After the convex rod on the blade shaft contacts the block, the blade angle is straight. At this time, the conveying structure is located on both sides of the blade. After the blade is leveled, the cleaning area can be greatly increased, and the cleaning effect can be improved to avoid the skewed angle affecting the cleaning. When the conveying structure is pushed to the blade position, the rectangular body on the fixed plate presses the switch, and the power supply of the motor is disconnected at this time, thereby avoiding the problem of false start. And through the continuous V-shaped arrangement of the special-shaped groove, the second ball drives the rotating drum to rotate reciprocatingly, and the conveying structure drives the cleaning cloth to reciprocate to clean the blades. When the second ball is below the special-shaped groove, the second ball can control the unidirectional rotation of the rotating drum through the arc surface of the arc groove until the second ball moves to the top of the special-shaped groove. This movement process can drag the cleaning cloth to move a certain distance, so as to adjust the cleaning position and avoid repeated cleaning of one surface to affect the cleaning effect of the blades. Moreover, when the convex rod and the block block block and the blade is locked, the blade is driven to rotate around the drive cylinder as the center, thereby meeting the cleaning needs of blades in different positions.

One end of the second electric push rod 2013 is fixedly connected to a telescopic rod 2015 and a spring 2014 by a connecting rod. One end of the spring 2014 and the telescopic rod 2015 is fixedly connected to a second ball 2016. The second ball 2016 is located at a node above the arc groove 204 and the special-shaped groove 205. The special-shaped groove 205 is a continuous V-shaped structure, and the groove depth of the special-shaped groove 205 decreases from top to bottom. The groove depth of the arc groove 204 is the same as the groove depth of the bottom of the special-shaped groove 205.

[0054] The transmission component 202 includes a conveying structure 2021, which is installed on a fixed plate 2011. One end of the conveying structure 2021 is fixedly connected to a second gear 2022, and the two second gears 2022 are meshed with each other. Two first Velcros 2023 are installed on the outside of the conveying structure 2021. The first Velcro 2023 is bonded to the second Velcro 2025, and the second Velcro 2025 is fixedly installed on the inner circle of the cleaning cloth 2024.

[0055] In this embodiment: the disc is pushed to move by the first electric push rod 1081, so that the ring gear 1085 is meshed with the first gear 1052. At this time, the ring gear 1085 and the first gear 1052 are transmitted by continuous advancement, and the blade shaft 1053 drives the blade 1051 to rotate, so that the protruding rod 1054 on the blade shaft 1053 contacts the stopper 1064. At this time, the angle of the blade 1051 is straight. At this time, the conveying structure 2021 is located on both sides of the blade 1051. After the blade 1051 is leveled, the cleaning area can be greatly increased, and the cleaning effect can be improved, and the cleaning effect can be avoided by avoiding the skewed angle from affecting the cleaning. Moreover, when the conveying structure 2021 is pushed to the position of the blade 1051, the rectangular body on the fixed plate 2011 presses the switch 109, and the power supply of the motor 1062 is disconnected at this time, thereby avoiding the problem of false start-up, and through the special-shaped The groove 205 is arranged in a continuous V-shape, so that the second ball 2016 reciprocates to drive the rotating drum 203 to rotate, and the conveying structure 2021 drives the cleaning cloth 2024 to reciprocate to clean the blade 1051. When the second ball 2016 is below the special-shaped groove 205, the second ball 2016 can control the rotating drum 203 to rotate in one direction through the arc surface of the arc groove 204 until the second ball 2016 moves to the top of the special-shaped groove 205. This movement process can drag the cleaning cloth 2024 to move a certain distance, so as to adjust the cleaning position and avoid repeated cleaning of one surface to affect the cleaning effect of the blade 1051. Moreover, when the convex rod 1054 and the block 1064 block the blade 1051, the blade 1051 is locked. At this time, the blade 1051 is driven to rotate around the drive cylinder 1063 as the center, thereby meeting the cleaning requirements of the blades 1051 at different positions.

[0056] Working principle: The first electric push rod 1081 drives the disc to move, so that the disc drives the connecting column 1072 to move through the rotating shaft 1086, and the connecting column 1072 drives the gear ring 1071 to move, and the gear ring 1071 is separated from the first gear 1052, and the disc also drives the gear ring 1085 to move through the torsion spring 1084, so that the gear ring 1085 meshes with the first gear 1052. At this time, through continuous advancement, the first ball 1087 controls the gear ring 1085 to rotate through the arc surface of the spiral groove 1088, and the gear ring 1085 and the first gear 1052 are transmitted, and the first gear 1052 drives the impeller 1053 to rotate The blade shaft 1053 drives the blade 1051 to rotate, so that the angle of the blade 1051 can be adjusted, so as to adjust the air volume. After the adjustment, the first electric push rod 1081 controls the gear ring 1085 to move away from the first gear 1052. At this time, the gear ring 1071 is also reset to mesh with the first gear 1052, and then the motor 1062 drives the drive cylinder 1063 to rotate. Since the gear ring 1071 is meshed and locked with the first gear 1052, the blade 1051 can rotate, so that air can be taken in through the heat exchanger 103, and the heat exchanger 103 can switch between cold and hot air according to actual use, so that the air volume is discharged through the output end 102;

[0057] When cleaning, the fixing plate 2011 is assembled on the transparent window 104, and is driven by the first gear 1052 through the gear ring 1085, so that the blade 1051 remains straight, and the protruding rod 1054 contacts the stopper 1064. At this time, after the transparent window 104 is closed, the rectangular body of the fixing plate 2011 contacts the switch 109, and the power supply of the motor 1062 is turned off. At the same time, the cleaning cloth 2024 is on both sides of the blade 1051. At this time, the second motor 1062 is controlled to drive the second ball 2016 to move, so that the second ball 2016 enters the special-shaped groove 205, and the special-shaped groove 205 controls the second ball 2016 to move. The control cylinder 203 rotates back and forth, and under the transmission of the two second gears 2022, the two conveying structures 2021 reciprocate synchronously, so that the cleaning cloth 2024 reciprocates to clean the blades 1051, and at this time the first electric push rod 1081 continues to control, so that the blades 1051 rotate around the drive cylinder 1063, so that the blades 1051 can be in the position of the cleaning cloth 2024 one by one, so that the cleaning cloth 2024 can perform the cleaning operation, and the second ball 2016 can move upward along the arc groove 204 again to the top of the special-shaped groove 205, so as to perform a cyclic cleaning operation.
