Description

Technical Field

[0001] This utility model relates to the field of skylight technology, specifically to an easily adjustable smoke exhaust skylight. Background Technology

[0002] Publication (Announcement) No.: CN114658173A, Publication (Announcement) Date: 2022-06-24, an invention patent application entitled "A Smoke Exhaust Skylight" includes: a window sash assembly having a rotatable connecting portion; a rotating component, one end of which is fixed to the building sill, and the other end of which is fixed to the rotatable connecting portion, the rotating component being used to rotate the window sash assembly around itself to open or close the window sash assembly relative to the skylight; and a first waterproof sealing component covering the rotatable connecting portion and extending beyond the side of the building sill away from the skylight to guide water on the window sash assembly to the side of the building sill away from the skylight. The smoke exhaust skylight provided by this application can prevent roof leaks.

[0003] In the prior art, including the aforementioned patents, skylights are generally kept closed to shield against rain or other impurities. The vent is only opened when the impeller is needed. Since the vent is usually installed on the roof, and is quite high above the ground, most existing opening methods are done by setting up a separate drive, while some are done manually. Regardless of the method, there are many inconveniences. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable smoke exhaust skylight to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An easily adjustable smoke exhaust skylight includes a mounting frame, in which a fan blade is rotatably connected, and the exhaust port of the mounting frame is rotatably connected to multiple sealing blocks; it also includes a sleeve coaxially sleeved on the fan blade, and a transmission component is provided between the sleeve and each sealing block, the stroke of the fan blade rotation causing the transmission component to drive each sealing block to rotate.

[0007] The sleeve is mounted on the drive shaft of the fan blade, and the sleeve moves in the axial direction of the drive shaft.

[0008] A transmission groove is formed around the periphery of the fan blade drive shaft, and multiple transmission protrusions that are adapted to the transmission groove are fixedly connected around the inside of the sleeve.

[0009] The transmission component includes multiple transmission components, with each transmission rod corresponding to a sealing block. One end of each transmission rod is hinged to the sealing block corresponding to it, and the other end of each transmission rod is hinged to a sleeve.

[0010] In the above technical solution, the present invention provides an easily adjustable smoke exhaust skylight, which drives each sealing block to rotate during the rotation of the fan blades, thereby causing each sealing block to open the exhaust port with gaps. When the sealing block is closed, due to the high air velocity and low pressure inside the mounting frame, a pressure difference is generated inside and outside the mounting frame, which better exhausts the smoke.

[0011] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0012] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0019] Reference Figure 1-2As shown, this utility model provides an easily adjustable smoke exhaust skylight, including a mounting frame 1, a fan blade 1.1 rotatably connected inside the mounting frame 1, and multiple sealing blocks 1.2 rotatably connected to the exhaust port of the mounting frame 1; it also includes a sleeve 1.3 coaxially sleeved on the fan blade 1.1, and a transmission component is provided between the sleeve 1.3 and each sealing block 1.2, the stroke of the fan blade 1.1 causing the transmission component to drive each sealing block 1.2 to rotate.

[0020] The sleeve 1.3 is mounted on the drive shaft of the fan blade 1.1, and the sleeve 1.3 moves in the axial direction of the drive shaft.

[0021] A transmission groove 1.10 is formed around the drive shaft of the fan blade 1.1, and multiple transmission protrusions 1.30 that are adapted to the transmission groove 1.10 are fixedly connected inside the sleeve 1.3.

[0022] The transmission component includes multiple transmission components. Each transmission rod 1.4 is correspondingly set with each sealing block 1.2. One end of each transmission rod 1.4 is hinged to the sealing block 1.2 corresponding to it, and the other end of each transmission rod 1.4 is hinged to the sleeve 1.3.

[0023] Specifically, such as Figure 1 As shown, the mounting frame 1 is a hollow cylindrical structure. Multiple mounting holes are provided at the air inlet end of the mounting frame 1, and multiple sealing blocks 1.2 are arranged around the exhaust end of the mounting frame 1. One end of each sealing block 1.2 is hinged to the exhaust end of the mounting frame 1. A fan blade 1.1 is coaxially rotatably connected inside the mounting frame 1. A rotor and commutator (not shown in the figure) are mounted on the drive shaft of the fan blade 1.1. A stator is installed inside the mounting frame 1 at the position corresponding to the rotor. Energy conversion is achieved through electromagnetic induction and magnetic field-current interaction, relying on Faraday's law. The fan blade 1.1 rotates within the mounting frame 1 using the laws of motion, Lorentz force, and Ampere's law. A transmission groove 1.10 is formed around the drive shaft of the fan blade 1.1, and the transmission groove 1.10 is composed of multiple V-shaped grooves connected end to end. A sleeve 1.3 is coaxially sleeved on the outside of the drive shaft of the fan blade 1.1. A transmission protrusion 1.30 is fixedly connected to the inner wall of the sleeve 1.3 at the position corresponding to each V-shaped groove. Each transmission protrusion 1.30 is located in each V-shaped groove. A transmission rod 1.4 is hinged between each sealing block 1.2 and the transmission protrusion 1.30.

[0024] During use, the rotation of the fan blade 1.1 drives the fan blade 1.1 drive shaft to rotate, which in turn causes the drive protrusion 1.30 on the sleeve 1.3 fitted on the drive shaft to engage with the drive groove 1.10, causing the sleeve 1.3 to reciprocate on the drive shaft. This causes the sleeve 1.3 to drive each drive rod 1.4 to move, which in turn causes the corresponding sealing block 1.2 to move. As the fan blade 1.1 rotates, it drives the sealing block 1.2 to open the exhaust port.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
