To simplify the disclosure of the embodiments of the present invention, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples of the embodiments of the present invention; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.

[0032] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an air conditioning heating and ventilation duct according to this utility model.

[0033] like Figures 1-7 As shown, this utility model embodiment provides an air conditioning heating and ventilation duct, including an air conditioning main duct 100 for connection to equipment. The upper end of the air conditioning main duct 100 is connected to a branch duct 200 for dispersing the gas inside the air conditioning main duct 100. Both the upper ends of the air conditioning main duct 100 and the branch duct 200 are equipped with filter sections 300 for filtering the internal circulating gas.

[0034] The filtration unit 300 includes a filter plate 340 for filtering gas and a mounting box 320 for mounting the filter plate 340. The mounting box 320 has connecting clips 310 on both sides for connecting to pipes. The filter plate 340 is slidably mounted inside a cavity opened inside the mounting box 320.

[0035] During the air conditioning heating and air supply process, the filter plate 340 installed inside the main air conditioning duct 100 and branch duct 200 filters the air supplied inside. The filter plate 340 is movably installed in the slot opened inside the mounting box 320. The filter plate 340 can be disassembled, installed and replaced by leaving an inspection port at the installation position. This ensures the cleanliness of the air inside the main air conditioning duct 100 and branch duct 200, filters dust and impurities in the air, and is simple and convenient to operate. It ensures the cleanliness of the air inside the duct and improves the overall maintenance efficiency of the air conditioning system.

[0036] The mounting box 320 includes a first mounting box 321 and a second mounting box 322 that can be spliced ​​together. The first mounting box 321 and the second mounting box 322 are sealed and fastened by connecting bolts at the connection points. The movable splicing of the first mounting box 321 and the second mounting box 322 makes it easy to disassemble and install, and it is highly flexible.

[0037] The lower end of the filter frame 341 is provided with a baffle plate for auxiliary sealing. The filter frame 341 is fixed to the outside of the slot at the lower end of the mounting box 320 by the baffle plate and the screws at the lower end. During normal use, the baffle plate is fixed by screws to seal the lower end of the slot, preventing internal air from leaking out from the mounting slot of the filter frame 341 and improving the performance.

[0038] A scraping unit 330 for cleaning the filter plate 340 is provided on one side. The scraping unit 330 includes a traction frame 331 for support and installation and a scraping component 333 for scraping dust from the filter plate 340 at the upper end of the traction frame 331. The two ends of the scraping component 333 are fixedly installed on the upper end of the traction frame 331 through a connecting frame. A return spring 332 for pushing the traction frame 331 to rebound is installed around both sides of the traction frame 331. The return spring 332 is installed inside the movable groove 323 opened on the side of the splicing box 322.

[0039] After a period of use, the inspection port can be opened and the traction frame 331 can be pulled down to drive the upper-mounted scraper 333 to descend, thereby scraping against the filter plate 340 to clean the surface of the filter plate 340, ensuring the filtration effect of the filter plate 340 and preventing dust accumulation and clogging.

[0040] The filter plate 340 is movably fitted into the slots inside the externally mounted filter screen frame 341 and is fastened with screws. One side of the filter plate 340 is flush with the filter screen frame 341, making it easy to disassemble, replace and clean the filter plate 340.

[0041] The dust scraper 333 includes a crossbar for support and fixation and an arc-shaped component. The outer side of the arc-shaped component is fitted to the side of the filter plate 340 and can be made of an elastic component. It can scrape the surface of the filter plate 340 and the arc shape facilitates the guidance of dust and the removal of dust. The elastic component can avoid damage to the filter plate 340 and protect the parts.

[0042] The lower end of the movable groove 323 is provided with a limiting hole 324 for limiting and sealing the traction frame 331. The lower end of the return spring 332 is located at the upper end of the limiting hole 324. The limiting hole 324 is matched with the size of the traction frame 331 to install and seal the traction frame 331.

[0043] A closing unit 400 for closing the branch pipe 200 is provided on one side. The closing unit 400 includes a connecting pipe 410 connected to the branch pipe 200 and a rotating component 420 movably installed in the inner cavity of the connecting pipe 410 for temporarily blocking the inner cavity of the pipe. Both the upper and lower ends of the rotating component 420 are movably installed in the inner cavity of the connecting pipe 410 through bearings, and are adjusted by a rotating handle 430 provided at the lower end. The rotating handle 430 is positioned by a through-mounted mounting shaft 440.

[0044] When some pipes are not in use, the rotating handle 430 inside the inspection port can be used to rotate and close the rotating part 420 inside the connecting pipe 410, thereby shutting off the pipe and preventing the internal heat from extending into other pipes and causing waste of resources.

[0045] The lower end of the connecting pipe 410 is fixedly installed with a positioning box 460 for supporting the mounting shaft 440. The mounting shaft 440 is installed through the hole opened at the upper end of the positioning box 460. The upper end of the positioning box 460 is provided with an arc-shaped sliding groove 470. The limiting post 450 fixedly installed at the upper end of the rotating handle 430 is movably installed inside the arc-shaped sliding groove 470 to limit the rotation of the rotating handle 430 and prevent the rotating handle 430 from shaking or deviating.

[0046] A working principle of an air conditioning heating and ventilation duct: During the air conditioning heating and air supply process, filter plates 340 installed inside the main air conditioning duct 100 and branch duct 200 filter the air supplied inside. The filter plates 340 are movably installed in the slots opened inside the mounting box 320. The filter plates 340 can be disassembled, installed and replaced by leaving an inspection port at the installation position, thus ensuring the cleanliness of the air inside the main air conditioning duct 100 and branch duct 200, filtering dust and impurities in the air inside. The operation is simple and convenient, ensuring the cleanliness of the air inside the duct, and improving the overall maintenance efficiency of the air conditioning system.

[0047] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
