Description

Technical Field

[0001] This utility model relates to exhaust ducts in buildings, and in particular to a highly airtight connecting support and a highly airtight exhaust duct that can be adjusted in all directions. Background Technology

[0002] Currently, most residential kitchen and bathroom exhaust systems use precast cement exhaust ducts. CN205296741U discloses a combined exhaust duct, which includes multiple exhaust pipe sections and multiple hollow sleeves. Adjacent exhaust pipe sections are connected through the same sleeve, and the sleeves are equipped with limiting plates around their perimeter. Currently, exhaust ducts on the market are manufactured in sections and installed by splicing them together on-site. Due to errors in manufacturing and installation processes, the joints between exhaust pipe sections cannot be perfectly aligned while maintaining overall verticality. These errors accumulate, causing the gaps at the joints to widen. Even with on-site adjustments, gaps remain, leading to smoke leakage.

[0003] Moreover, most residential buildings are now high-rise buildings. As the floors are stacked, the weight of the exhaust ducts on the lower floors is concentrated on the exhaust ducts, which can easily cause deformation of the exhaust ducts and make the gaps at the joints larger and larger. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a highly airtight connecting support and a universally adjustable highly airtight exhaust duct, which can distribute the weight of each exhaust duct section to each floor slab. It can be universally adjusted according to building errors during on-site construction, and the joints between each exhaust duct section maintain high airtightness.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] A high-tightness connection support includes a body, at least one end of which is provided with a spherical arc edge for airtight connection with the end opening of an exhaust duct; a fixing member is provided in the middle of the body, which is embedded in and connected to a wall or floor slab; and a through hole is provided on the body for connecting the exhaust ducts of the upper and lower floors.

[0007] The through-hole is aligned with the central axis of the body.

[0008] One end of the main body is a spherical arc edge, and the other end is a circular tube. The circular tube is inserted into the end opening of the exhaust channel and is airtightly connected; or both ends are spherical arc edges, and the spherical arc edges at both ends are airtightly connected to the end openings of the exhaust channels of the upper and lower layers, respectively.

[0009] The spherical arc edge is a spherical convex arc edge, and the exhaust duct end opening that is airtightly connected to it is provided with a spherical concave arc edge; the spherical arc edge is a spherical concave arc edge, and the exhaust duct end opening that is airtightly connected to it is provided with a spherical convex arc edge.

[0010] The device is equipped with several U-shaped support adjustment grooves, and the fixing member can be adjusted up and down in the adjustment grooves and locked by nuts.

[0011] The body has a reinforcing rib in the middle.

[0012] A highly sealed exhaust duct with universal adjustment includes multiple exhaust duct sections, each exhaust duct section has an air inlet on its side, and adjacent exhaust duct sections are universally connected by the aforementioned highly sealed connecting support.

[0013] Compared to existing technologies, the advantages of this invention are as follows: Because adjacent exhaust duct sections are connected by a high-tightness connecting support, this invention allows for omnidirectional adjustment during on-site construction based on building errors, avoiding the accumulation of errors. The spherical arc-edged through-hole connector fits tightly with the end openings of each exhaust duct section. This maintains a high-tightness connection between each exhaust duct section, effectively preventing waterproofing, smoke transmission, and odor transfer. The high-tightness connecting support is inserted into the inner layer of the lower exhaust duct, and the connecting support is integrated with each floor level by adjusting the fixing components. This allows each exhaust duct to bear its own weight independently on each floor, preventing relative pressure between exhaust ducts and thus preventing exhaust duct deformation.
