Description

Technical Field

[0001] This utility model relates to the field of air duct technology, and in particular to an improved purification air duct that is easy to install. Background Technology

[0002] Composition of air ducts: Air ducts are pipeline systems used for air transport and distribution. Air ducts can be classified according to cross-sectional shape and material. According to cross-sectional shape, air ducts can be divided into various types such as circular air ducts, rectangular air ducts, and flat oval air ducts. Among them, circular air ducts have the lowest resistance and the largest height dimension, and are more complex to manufacture, so rectangular air ducts are mainly used. According to material, air ducts can be divided into metal air ducts, composite air ducts, etc.

[0003] Existing ductwork cannot capture and collect dust and particles passing through it, making it inconvenient to filter and clean smoke particles generated during industrial production. This results in dust or smoke particles accumulating in the ductwork over a long period of time, making it difficult to clean and increasing the overall cleaning difficulty. For example, Chinese patent document CN222458755U, published on February 11, 2025, discloses a utility model patent for "a duct for capturing and purifying smoke particles". This patent includes a duct body, with a plug-in frame fixedly connected to one side of the duct body and a snap-fit ​​frame adapted to the plug-in frame fixedly connected to the other side. An installation frame is detachably connected inside the duct body, and a fixing frame is fixedly connected to the inner wall of the installation frame. The fixing frame has an installation groove inside, and a filter screen for capturing and filtering smoke particles is detachably connected inside the installation groove. This achieves the capture and purification of smoke particles inside the duct by the filter screen, and the detachable installation frame facilitates the replacement of the filter screen. However, this solution uses multiple fixing screws and threaded connections to fix the two sets of duct bodies, which is time-consuming and has low work efficiency. Summary of the Invention

[0027] refer to Figures 1-9An improved purification duct that is easy to install includes a duct body 1 and a connecting component 2 that can be detachably disposed between two adjacent duct bodies 1. The outer walls at both ends of the duct body 1 are symmetrically provided with snap-fit ​​plates 101 in a U-shape, and the top end faces at both ends of the duct body 1 are provided with mating plates 102 corresponding to the snap-fit ​​plates 101.

[0028] The connecting assembly 2 includes a U-shaped connecting frame 21 and a connecting plate 22 detachably mounted on the connecting frame 21. The inner wall of the connecting frame 21 has a snap-fit ​​groove 211 for inserting two snap-fit ​​plates 101 when connecting adjacent duct bodies 1 end-to-end. A connecting groove 212 for inserting the connecting plate 22 is provided through the connecting frame 21. A hollow fixing seat 213 is provided on the top surface of one side of the connecting frame 21. A docking groove 221 for inserting a docking plate 102 is provided on the bottom of one side of the connecting plate 22. The connection strength between the connecting plate 221 and the connecting plate 102, and between the connecting groove 211 and the connecting plate 101, is improved. By inserting the connecting plate 22 into the connecting groove 212 of the connecting frame 21, the adjacent two duct bodies 1 are further limited and fixed. The connecting plate 22 is provided with a first handle 222 on the other side. The top end face of the connecting plate 22 is provided with a first mounting groove 223. The mounting frame 23 is detachably provided in the first mounting groove 223.

[0029] Furthermore, one side of the mounting frame 23 is provided with a plug-in groove 231, and a filter screen 232 is detachably provided in the plug-in groove 231. The top end face of the mounting frame 23 is provided with a cover plate 233, and the top end face of the cover plate 233 is provided with a second handle 234.

[0030] Furthermore, the bottom end face of the cover plate 233 is provided with a first magnet 235, and the top end face of the connecting plate 22 is provided with a second magnet 224 that is magnetically attracted to the first magnet 235. The magnetic attraction between the first magnet 235 on the bottom end face of the cover plate 233 and the second magnet 224 on the top end face of the connecting plate 22 improves the stability of the installation frame 23 and facilitates the disassembly of the installation frame 23, thereby making it easier to replace the filter screen 232.

[0031] Furthermore, a fixing rod 214 is slidably connected inside the fixing base 213. One end of the fixing rod 214 extends to the outside of the fixing base 213 and is provided with an operating plate 215. The other end of the fixing rod 214 extends into the connecting groove 212. A pressure plate 216 is fixedly connected to the fixing rod 214 inside the fixing base 213. A return spring 217 is sleeved on the outside of the fixing rod 214 above the pressure plate 216.

[0032] Furthermore, the top end face of the connecting plate 22 is provided with a fixing hole 225 for the fixing rod 214 to be inserted. By inserting the fixing rod 214 into the fixing hole 225 of the connecting plate 22, the connecting plate 22 is fixedly installed on the connecting frame 21, thereby making the two adjacent air duct bodies 1 stably connected.

[0033] Furthermore, the inner sidewall of the connecting frame 21 is provided with a second mounting groove 218 for the bottom of the mounting frame 23 to be inserted. The second mounting groove 218 makes the mounting frame 23 more stable after insertion and installation.

[0034] The working principle of this utility model:

[0035] During installation, first, align the snap-fit ​​groove 211 of the connecting bracket 21 with the snap-fit ​​plate 101 at the connection point of the two adjacent duct bodies 1 and insert it. Then, pull the operating plate 215 upward to move the pressure plate 216 synchronously. The pressure plate 216 compresses the return spring 217, causing the return spring 217 to deform until the fixing rod 214 disengages from the connecting groove 212. Then, align the connecting plate 22 with the connecting groove 212 of the connecting bracket 21 and insert it. At the same time, the mating plate 102 at the connection point of the two duct bodies 1 is inserted into the mating groove 221 of the connecting plate 22. Then, release the operating plate 215. After the return spring 217 is released from external force, it returns to its original shape and drives the fixing rod 214 to be inserted into the fixing hole 225 of the connecting plate 22, thereby connecting the two duct bodies 1. Plate 22 is fixedly installed on connecting frame 21, thereby making the two adjacent air duct bodies 1 stably connected. The setting of connecting component 2 replaces the fixing method of screw and screw hole thread connection, making the operation process more time-saving and convenient, and improving the installation and disassembly efficiency. Finally, the mounting frame 23 with filter screen 232 installed is aligned with the first mounting groove 223 of connecting plate 22 and inserted. At the same time, the bottom of mounting frame 23 is inserted into the second mounting groove 218 of connecting frame 21. The first magnet 235 on the bottom end face of cover plate 233 and the second magnet 224 on the top end face of connecting plate 22 are magnetically attracted, which improves the stability of mounting frame 23 installation and facilitates the disassembly of mounting frame 23, thereby facilitating the replacement of filter screen 232.
