Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan muffler. Background Art

[0002] A damper usually refers to a device used to regulate air circulation. Its main function is to control the flow of air, that is, to control the ventilation volume.

[0003] However, most of the existing dampers are flip-type dampers that open and close, and the blades flip inside the cylinder to adjust the ventilation volume, which requires a large space. In special occasions, due to space limitations, a thin and lightweight damper product is needed that can adjust the ventilation volume in a narrow space. Utility Model Content

[0030] Reference Figure 1 and Figure 2 , plate-type air damper.

[0031] It includes an annular disk, called a fixed disk 1, the opening in the middle of the fixed disk 1 is a vent; it also includes a door leaf 3 for adjusting the size of the vent, and the door leaf 3 is provided with at least two; the fixed disk 1 is provided with a first rotating shaft 5 for mounting the door leaf 3, the number of the first rotating shaft 5 is the same as the number of the door leaves 3, and the axis of the first rotating shaft 5 is parallel to the axis of the fixed disk 1; it also includes a rotary opening and closing mechanism for driving the door leaf 3 to rotate along the first rotating shaft 5; the rotary opening and closing mechanism includes a structure for driving all the door leaves 3 to move synchronously; the axis of the first rotating shaft 5 of the air regulating door leaf 3 is parallel to the axis of the fixed disk 1; It is parallel to the axis of the fixed disk 1, so that the door leaf 3 moves along the surface of the fixed disk 1 to open the vent when it is rotated to open. The door leaf 3 of the non-flip opening and closing air regulating door requires a larger space to open. The opening method adopted by this patent enables the door leaf 3 to move along the surface of the fixed disk 1 to save space; secondly, there are at least two door leaves 3, and multiple door leaves 3 can save the length required to open a single door leaf 3, so that the air regulating door can save more space; finally, all door leaves 3 are opened synchronously with a rotating opening and closing mechanism, so that all door leaves 3 will not affect each other when opening, causing the door leaves 3 to get stuck.

[0032] The rotating opening and closing mechanism includes another annular disk, called a movable disk 2, and the rotation axis of the movable disk 2 coincides with the axis of the fixed disk 1; the movable disk 2 is provided with second rotating shafts 6 that are the same in number as the door leaves 3; each second rotating shaft 6 is provided with a driving bar 4, and each driving bar 4 is provided with a third rotating shaft 7 connected to a door leaf 3; the position of the third rotating shaft 7 on each door leaf 3 is consistent; the use of the movable disk 2 can synchronously drive the door leaf 3 with the driving bar 4, and the driving bar 4 is movably connected to the movable disk 2 by the second rotating shaft 6, and is movably connected to the door leaf 3 by the third rotating shaft 7, so that all door leaves 3 can be opened smoothly when the movable disk 2 rotates.

[0033] The thickness of the movable plate 2 is 0.2-0.4 cm; the thickness of the fixed plate 1 is 0.1-0.3 cm; the thickness of the door leaf 3 is 0.1-0.3 cm; the thickness of the movable plate 2, the fixed plate 1 and the door leaf 3 are all within a certain range so that the air regulating door can fit into a sufficiently narrow space.

[0034] During use, when the air regulating door needs to adjust the size of the vent, the movable disk 2 rotates, and the movable disk 2 drives all the driving strips 4 to drive the door leaves 3 connected to each driving strip 4. The door leaves 3 rotate along the first rotating shaft 5. When the door leaves 3 rotate to open, they move along the surface of the fixed disk 1 to open the vent. The movement of the door leaves 3 along the surface of the fixed disk 1 saves space. The driving strip 4 is movably connected to the movable disk 2 by the second rotating shaft 6 and is movably connected to the door leaves 3 by the third rotating shaft 7, so that all the door leaves 3 can be smoothly opened when the movable disk 2 rotates.

[0035] Example 2

[0036] Reference Figure 1 and Figure 2 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0037] The edge of each door leaf 3 has a side strip with a thickness of at least 0.2 cm; by providing the side strip, the door leaves 3 will not be staggered and stuck when closing each other.

[0038] The edge strip is made of rubber material and is arranged on a side away from the fixed plate 1 ; the edge strip made of rubber material increases the sealing performance of the door leaf 3 after it is closed.

[0039] The movable disk 2 is provided with an arc groove 21 , and the axis of the arc groove 21 coincides with the rotation axis of the movable disk 2 .

[0040] The movable disk 2 is also provided with a fixed block 8 that clamps the edge of the movable disk 2, and the fixed block 8 is provided with a guide column, which can be slidably set in the circular arc groove 21; by setting the circular arc groove 21 and the fixed block 8, the guide column enables the movable disk 2 to move within a fixed range in the circular arc groove 21, and the fixed block 8 ensures the stable rotation of the movable disk 2, thereby ensuring the stable opening of the door leaf 3.

[0041] The number of the door leaves 3 is at least five, which further reduces the range of the door leaves 3 and enables the air damper to save more space.

[0042] The driving mechanism of the movable disk 2 adopts at least one of a gear mechanism, a friction wheel mechanism, and a magnetic suspension driving mechanism to ensure the smooth rotation of the driving mechanism of the movable disk 2.

[0043] When in use, when the door leaf 3 is closed, the edge strips of the door leaf 3 will first contact each other to prevent the door leaves 3 from being stuck together. When the movable disk 2 rotates, the guide posts in the fixed block 8 slide in the arc groove 21. When the door leaf 3 is opened or closed, the guide posts also move to the two ends of the arc groove 21 to prevent the movable disk 2 from being driven by the driving mechanism to turn around and cause the door leaf 3 to be squeezed and deformed. Five door leaves 3 are provided, so that the air regulating door can save more space.
