[0026] Example

[0027] like Figures 1 to 5 As shown, this utility model proposes a ventilation and air exchange device for four types of business warehouses, including a ventilation pipe 1 installed in a ventilation opening. One end of the ventilation pipe 1 is also fixedly connected to a metal protective net 7, which provides safety protection for the ventilation pipe 1. A sleeve 5 is fixedly connected inside the ventilation pipe 1, providing fixed support for a cylinder 51. The middle part of the sleeve 5 is fixedly connected to the cylinder 51. A first fan 2 and a second fan 3 are installed inside the ventilation pipe 1. The first fan 2 provides inefficient ventilation and is used with a small ventilation opening to reduce moisture intrusion. The second fan 3 provides efficient ventilation and is used with a large ventilation opening to enhance air circulation. A cylinder 51 with a drive mechanism connected to the first fan 2 and the second fan 3 is provided inside the ventilation pipe 1. A storage slot 65 is provided inside the ventilation pipe 1, providing storage space for a baffle 4. A pair of baffles 4 are slidably connected inside the storage slot 65 to block the first fan 2. The baffles 4 open the ventilation path by opening and closing, adjusting the size of the ventilation opening. A pair of protrusions 41 are fixedly connected to each baffle 4, and each protrusion 41 is provided with a ball bearing 44, which assists the baffle 4 in sliding within the storage slot 65. Each protrusion 41 is provided with a ball bearing 44 that slidably connects with the inner wall of the storage slot 65, reducing friction when the baffle 4 slides.

[0028] Among them, such as Figures 2 to 4As shown, the ventilation duct 1 is equipped with a drive mechanism that allows the first fan 2 and the second fan 3 to switch alternately. The drive mechanism includes a motor 52 fixedly connected to the piston rod of the cylinder 51. The motor 52 provides power for the rotation of the fans and can move with the piston rod of the cylinder 51. The output shaft of the motor 52 is fixedly connected to a shaft 53. A first locking tooth 54 is fixedly connected to the outer wall of the shaft 53. The first locking tooth 54 can lock the internal gear 232 of the first fan 2, driving it to rotate. A plug 55 is fixedly connected to the end of the shaft 53 away from the motor 52. A second locking tooth 56 is fixedly connected to the outer wall of the plug 55. The second locking tooth 56 can lock the internal gear 232 of the second fan 3, driving it to rotate. One end of both the first fan 2 and the second fan 3 is fixedly connected to an internal gear 232 that is locked by the ends of the first locking tooth 54 and the second locking tooth 56. The internal gear 232 can be locked by the ends of the first locking tooth 54 or the second locking tooth 56, so that the corresponding first fan 2 and second fan 3 are connected to the drive mechanism and rotate with it.

[0029] In addition, such as Figures 2 to 4 As shown, both the first fan 2 and the second fan 3 have a slot 231 at the end away from the internal gear 232. The slot 231 allows the collar 233 to be movably fitted, assisting in the positioning of the first fan 2 and the second fan 3. The collar 233 is movably fitted inside the slot 231, providing support for the fan and assisting its rotation. A pair of support rods 234 are fixedly connected to the outer wall of the collar 233, supporting the collar 233 and the first fan 2 and the second fan 3. The ends of the support rods 234 away from the collar 233 are fixedly connected to the inner wall of the ventilation duct 1.

[0030] It is worth noting that, such as Figure 2 and Figure 3As shown, the ventilation duct 1 has a transmission mechanism inside that is linked to the drive mechanism. The transmission mechanism is used to open and close a pair of baffles 4. The transmission mechanism includes a pair of sliding grooves 6 inside the ventilation duct 1. The sliding grooves 6 provide a path for the pull rod 61 to slide. The pull rod 61 is slidably connected inside each of the sliding grooves 6. When the pull rod 61 abuts against the inner wall of one end of the sliding groove 6, the second locking tooth 56 engages with the internal gear 232 on the second fan 3. When the pull rod 61 abuts against the inner wall of the other end of the sliding groove 6, the first locking tooth 54 engages with the internal gear 232 on the first fan 2. The end of the pull rod 61 away from the sliding groove 6 is fixedly connected to the outer wall of the motor 52. The sliding groove 6 has a connecting groove 62 inside that communicates with the storage groove 65. The end of the connecting groove 62 near the storage groove 65 is rotatably connected to a rope pulley 64. The pull rope 63 passes through the rope pulley 64, with one end connected to the pull rod 61 and the other end connected to the baffle 4, pulling the baffle 4 to open and close. The connecting groove 62 has a pull rope 63 that passes through the rope pulley 64. The pull rope 63 is rotatably connected to one end of the connecting groove 62 near the receiving groove 65, supporting and guiding the pull rope 63. One end of the pull rope 63 is fixedly connected to the end of the pull rod 61, and the other end of the pull rope 63 is fixedly connected to the corresponding baffle 4.

[0031] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, both ends of the baffle 4 are provided with telescopic grooves 42, and springs 43 are connected inside the telescopic grooves 42 to provide space for the baffle 4 to reset. A pair of springs 43 corresponding to the telescopic grooves 42 are provided in the middle of a pair of baffles 4. The springs 43 can be stretched and reset, mainly to drive the pair of baffles 4 to close. One end of the spring 43 is fixedly connected to the inner wall of the corresponding telescopic groove 42.

[0032] In this embodiment, when using the ventilation and air exchange device for the four types of business warehouses, the metal protective mesh 7 can provide safety protection for the ventilation duct 1. When the cylinder 51 is started, its piston rod drives the motor 52 to move. The motor 52 drives the insert block 55 on the shaft 53 to move, causing the insert block 55 to engage the second locking tooth 56 with the internal gear 232 on the second fan 3. At this time, the motor 52 starts, causing the second fan 3 to rotate and ventilate the ventilation duct 1, while the first fan 2 is in the off state. When the cylinder 51 is started again, the shaft 53 drives the first locking tooth 54 to engage with the internal gear 232 on the first fan 2, while the second locking tooth 56 disengages from the internal gear 232 on the second fan 3. When the motor 52 is started again, the corresponding first fan 2 rotates for ventilation, while the other second fan 3 remains off, achieving alternating switching.

[0033] Simultaneously, when the motor 52 moves, it drives the pull rods 61 in a pair of sliding grooves 6 to slide. The ends of the pull rods 61 away from the motor 52 pull the baffles 4 in the storage groove 65 through the pull ropes 63 in the connecting groove 62. The ball bearings 44 on the baffles 4 slide along the inner wall of the storage groove 65, and the springs 43 in the telescopic groove 42 are stretched, causing the pair of baffles 4 to open and no longer block the first fan 2, ensuring smooth ventilation in the ventilation pipe 1 when the first fan 2 rotates.

[0034] When cylinder 51 drives motor 52 to reset, the first locking tooth 54 disengages from the internal gear 232 on the corresponding first fan 2, and the baffle 4 resets under the elastic action of spring 43, blocking the first fan 2 again. The first fan 2 and the second fan 3 rotate under the support of the central collar 233 of a pair of support rods 234, with the locking groove 231 assisting in their positioning, further adapting to ventilation needs. Through this coordination, the first fan 2 or the second fan 3 can be activated according to the temperature and humidity conditions in the warehouse, thereby adjusting the ventilation volume in the ventilation duct 1 and improving ventilation flexibility.

[0035] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
