[0039] See also Figure 1-5 The present invention provides a terminal fire protection design structure of an assembled ceiling fresh air system, which includes:

[0040] A ceiling panel 1, on which a fresh air duct 2 is arranged, and at least one installation cavity 3 is respectively arranged on both sides of the fresh air duct 2;

[0041] A partition component 4, wherein at least one partition component 4 is provided on the fresh air duct 2, and the partition component 4 includes a partition component 41, a driving component 42 and a pulling component 43. The partition component 41 is a folding structure, and the partition component 41 is arranged in the fresh air duct 2. One end of the partition component 41 is connected to the fresh air duct 2, and the other end of the partition component 41 is connected to a fixing plate 5. The top of the fixing plate 5 is connected to the driving component 42. The pulling component 43 is arranged in the installation cavity 3, and one end of the pulling component 43 is inserted into a slot at the end of the fixing plate 5.

[0042] The pulling component 43 includes a pull rope 431, a first spring 432 and a latch 433. The first spring 432 is arranged in the installation cavity 3. The installation cavity 3 is filled with paraffin 6. The paraffin 6 compresses the first spring 432. One end of the pull rope 431 is connected to the first spring 432 near one end of the paraffin 6. The other end of the pull rope 431 passes through the installation cavity 3 and is connected to the latch 433. The latch 433 is inserted into the slot. The metal box is heated and transfers heat to the paraffin. The paraffin melts and flows from the upper cavity into the lower cavity. The paraffin releases the restriction on the first spring, and the compressed first spring unfolds.

[0043] A metal box 7 is disposed on the side of the fresh air duct 2, the installation cavity 3 is disposed in the metal box 7, the installation cavity 3 is divided into an upper cavity 31 and a lower cavity 32 by a partition, the upper cavity 31 and the lower cavity 32 are connected by a through hole, and the pull rope 431 and the first spring 432 are disposed in the upper cavity 31. In this way, the paraffin will not flow out of the metal box, which is safer.

[0044] The top of the fresh air duct 2 is provided with an installation box 8, the partition component 41 is stored in the installation box 8, and the opening at the bottom of the installation box 8 is connected to the fresh air duct 2. The partition component is stored in the installation box without affecting the ventilation of the fresh air duct.

[0045] Slide grooves are respectively arranged on both sides of the installation box 8, and the slide grooves extend to the bottom of the fresh air duct 2. The fixing plate can slide downward in a straight line to improve the sealing effect.

[0046] The installation box 8 has a through hole 9 at a position corresponding to the slot. The through hole facilitates the insertion and exit of the latch into and out of the slot.

[0047] The driving component 42 is a spring, one end of which is connected to the installation box 8, and the other end of which is connected to the fixing plate 5. When the partition component is in the storage state, the spring is in a compressed state, and can provide power for the fixing plate to move when the lock is released.

[0048] The fixing plate 5 is provided with a first magnet, and the fresh air duct 2 is provided with a second magnet that attracts the first magnet, and the second magnet is located directly below the first magnet. This can make the fixing plate and the fresh air duct contact more tightly and firmly, thereby improving the sealing effect.

[0049] The partition component 41 is a fireproof curtain.

[0050] Working principle: By setting a partition component on the fresh air duct, the partition component can divide the channel inside the fresh air duct into multiple independent areas, forming multiple barriers to prevent smoke and flames from entering other floors along the duct, which is safe. In the event of a fire, the metal box is heated and transfers heat to the paraffin, which melts and flows from the upper cavity to the lower cavity. The paraffin releases the restriction on the first spring, and the compressed first spring unfolds, thereby pulling the pull rope, and the pull rope then pulls the pin to separate the pin from the fixed plate. Under the action of the driving component, the partition component unfolds, and the fixed plate is adsorbed by the first magnet and the second magnet, so that the inside of the fresh air duct can be partitioned, which achieves a good isolation purpose and further achieves the purpose of fire prevention.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
