[0001] The present application relates to the technical field of ventilation ducts, and specifically relates to a ventilation duct with a filtering function for air conditioning purification. Background Art

[0002] A ventilation duct is a duct system used for ventilation, air change, smoke exhaust, etc. in a building. It can introduce fresh air, discharge the polluted air indoors, and keep the indoor air fresh and comfortable.

[0003] A prior patent (publication number: CN 215982890 U) discloses a ventilation duct with a filtering function for air conditioning purification, including: a pipe body; a connecting frame, the connecting frame is fixed to the top end of the pipe body, and a sliding groove is opened inside the connecting frame; an opening, the opening is opened on one side of the connecting frame and communicates with the sliding groove; a U-shaped plate, the U-shaped plate is slidably connected to both sides of the inner wall of the sliding groove. The ventilation duct with a filtering function for air conditioning purification provided by the present utility model, through the provided U-shaped plate and sliding inside the connecting frame, enables the filter element to be pulled out for cleaning in a drawable structure, without the trouble of disassembly and cleaning. After the cleaning is completed, by pushing the filter element, it enters the connecting frame to perform daily filtration on the ventilation duct, thus simplifying the cleaning steps, with simple operation and convenient use, reducing the workload of the operator, and improving the cleaning efficiency.

[0004] The filter element of the above ventilation duct is positioned by a magnet and a spring. Although it is convenient to disassemble and clean the filter element, the magnet and the spring cannot completely position the filter element, resulting in certain defects in the stability of the filter element. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present application provides a ventilation duct with a filtering function for air conditioning purification, which has the advantages of being convenient for disassembling and cleaning the filter plate, and at the same time improving the stability of the filter plate, and solves the problem that the filter element of the existing ventilation duct is positioned by a magnet and a spring. Although it is convenient to disassemble and clean the filter element, the magnet and the spring cannot completely position the filter element, resulting in certain defects in the stability of the filter element.

[0006] To achieve the above object, the present application provides the following technical solution: A ventilation duct with a filtering function for air conditioner purification, including a pipe body, a connection frame is fixedly connected to the upper surface of the pipe body, a chute is opened inside the connection frame, the connection frame is slidably connected with an outer frame through the chute, a filter plate is fixedly connected to the inner wall of the outer frame, two first lead screws are rotatably inserted into the connection frame, a positioning rod is threadedly connected to the outer circumferential surface of each first lead screw, two sliders are slidably connected inside the outer frame, two limiting grooves are opened inside the connection frame, and the outer surfaces of the sliders are slidably connected with the connection frame through the limiting grooves respectively.

[0007] Through the above solution, since the filter element of the existing ventilation duct is positioned by a magnet and a spring, although it is convenient to disassemble and clean the filter element, the magnet and the spring cannot completely position the filter element, resulting in certain defects in the stability of the filter element. By rotating the first lead screw to drive the positioning rod to move, the positioning rod is promoted to move into or out of the positioning hole, so as to facilitate moving the outer frame and the filter plate out of the connection frame for cleaning, and improve the positioning stability between the outer frame and the connection frame. By rotating the second lead screw to drive the threaded pipe and the push plate to move, the slider is promoted to move in and out under the action of the bearing plate and the spring, so as to limit the outer frame and prevent the outer frame from easily falling off from the inside of the connection frame, and it is convenient to completely remove the outer frame and the filter plate from the inside of the connection frame for replacement.

[0008] Further, two positioning holes are opened inside the outer frame, and the outer circumferential surfaces of the positioning rods are slidably inserted into the outer frame through the positioning holes respectively.

[0009] Through the above solution, the outer frame is completely positioned by the positioning rod and the positioning hole, the stability of the outer frame and the filter plate is improved, and it is convenient to move the outer frame and the filter plate out of the connection frame for cleaning.

[0010] Further, a first limiting ring is fixedly sleeved on the outer circumferential surface of each first lead screw, and the outer circumferential surface of the first limiting ring is rotatably connected to the inside of the connection frame.

[0011] Through the above solution, the first lead screw is restricted to prevent the first lead screw from sliding and shifting, and the stability of the movement of the first lead screw is increased.

[0012] Further, two first limiting blocks are fixedly connected to the outer circumferential surface of each positioning rod, and the outer surfaces of each first limiting block are slidably connected to the connection frame through the empty slots opened inside the connection frame.

[0013] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating with the first lead screw, and the positioning rod is promoted to always move horizontally.

[0014] Further, two second lead screws are rotatably inserted into the interior of the outer frame. A threaded tube is threadedly connected to the outer circumferential surface of each second lead screw. A push plate is fixedly connected to the back surface of the threaded tube. A receiving plate is fixedly connected to the front surface of each slider. One end of the receiving plate close to the push plate is of an inclined surface structure.

[0015] Through the above solution, by rotating the second lead screw, the threaded tube and the push plate are driven to move, so that the slider moves in and out under the action of the inclined surface of the receiving plate and the spring, thereby limiting the outer frame, preventing the outer frame from easily falling off from the interior of the connecting frame, and facilitating the complete removal of the outer frame and the filter plate from the interior of the connecting frame for replacement.

[0016] Further, a spring is fixedly connected to the outer surface of each slider. The other end of the spring is fixedly connected to the interior of the outer frame.

[0017] Through the above solution, the spring can exert a pulling force on the slider, causing the slider to automatically move back and no longer limit the outer frame.

[0018] Further, a second limiting ring is fixedly sleeved on the outer circumferential surface of each second lead screw. The outer circumferential surface of the second limiting ring is rotatably connected to the interior of the outer frame.

[0019] Through the above solution, the second lead screw is limited to prevent the second lead screw from sliding and shifting, and the stability of the movement of the second lead screw is increased.

[0020] Further, two second limiting blocks are fixedly connected to the outer circumferential surface of each threaded tube. The outer surface of each second limiting block is slidably connected to the outer frame through an empty groove opened in the interior of the outer frame.

[0021] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating along with the second lead screw, and the threaded tube is always moved horizontally.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For the ventilation duct with a filtering function for air-conditioning purification, by rotating the first lead screw to drive the positioning rod to move, the positioning rod is moved into or out of the positioning hole, and by rotating the second lead screw to drive the threaded tube and the push plate to move, the slider moves in and out under the action of the receiving plate and the spring, achieving the effect of facilitating the removal of the outer frame and the filter plate from the connecting frame for cleaning, improving the positioning stability between the outer frame and the connecting frame, being able to limit the outer frame, preventing the outer frame from easily falling off from the interior of the connecting frame, and facilitating the complete removal of the outer frame and the filter plate from the interior of the connecting frame for replacement, and solving the problem of low stability of the filtering element of the existing ventilation duct.

The outer frame 4 is completely positioned through the positioning rods 7 and the positioning holes 8, improving the stability of the outer frame 4 and the filter plate 5, and facilitating the removal of the outer frame 4 and the filter plate 5 from the connecting frame 2 for cleaning.

[0036] Please refer to Figure 3 and Figure 7 , a first limiting ring 9 is fixedly sleeved on the outer circumferential surface of each first lead screw 6, and the outer circumferential surface of the first limiting ring 9 is rotatably connected to the inside of the connecting frame 2, restricting the first lead screw 6 to prevent the first lead screw 6 from sliding and offsetting, and increasing the stability of the movement of the first lead screw 6.

[0037] Please refer to Figure 3 and Figure 7 , two first limiting blocks 10 are fixedly connected to the outer circumferential surface of each positioning rod 7, and the outer surfaces of each first limiting block 10 are slidably connected to the connecting frame 2 through the empty slots provided inside the connecting frame 2, restricting the positioning rod 7 to prevent the positioning rod 7 from rotating along with the first lead screw 6, and prompting the positioning rod 7 to always move horizontally.

[0038] Please refer to Figure 3 and Figure 6 , two second lead screws 13 are rotatably inserted into the inside of the outer frame 4, a threaded tube 14 is threadedly connected to the outer circumferential surface of each second lead screw 13, a push plate 15 is fixedly connected to the back of the threaded tube 14, a receiving plate 16 is fixedly connected to the front of each slider 11, and one end of the receiving plate 16 close to the push plate 15 is of an inclined surface structure. By rotating the second lead screw 13, the threaded tube 14 and the push plate 15 are driven to move, prompting the slider 11 to move in and out under the action of the inclined surface of the receiving plate 16 and the spring 17, thereby limiting the outer frame 4, preventing the outer frame 4 from easily falling off from the inside of the connecting frame 2, and facilitating the complete removal of the outer frame 4 and the filter plate 5 from the inside of the connecting frame 2 for replacement.

[0039] Please refer to Figure 3 and Figure 6 , a spring 17 is fixedly connected to the outer surface of each slider 11, and the other end of the spring 17 is fixedly connected to the inside of the outer frame 4. The spring 17 can apply a pulling force to the slider 11, prompting the slider 11 to automatically move back and no longer limit the outer frame 4.

[0040] Please refer to Figure 3 and Figure 7, a second limiting ring 18 is fixedly sleeved on the outer circumferential surface of each second lead screw 13, and the outer circumferential surface of the second limiting ring 18 is rotationally connected to the inside of the outer frame 4 to limit the second lead screw 13 and prevent the second lead screw 13 from sliding and shifting, thereby increasing the stability of the movement of the second lead screw 13.

[0041] Please refer to Figure 3 and Figure 6 , two second limiting blocks 19 are fixedly connected to the outer circumferential surface of each threaded tube 14, and the outer surface of each second limiting block 19 is slidably connected to the outer frame 4 through an empty groove opened inside the outer frame 4 to limit the threaded tube 14 and prevent the threaded tube 14 from rotating with the second lead screw 13, so as to ensure that the threaded tube 14 always moves horizontally.

[0042] In this embodiment, a ventilation duct with a filtering function for air conditioner purification drives the positioning rod 7 to move by rotating the first lead screw 6, so that the positioning rod 7 moves into or out of the positioning hole 8. By rotating the second lead screw 13, the threaded tube 14 and the push plate 15 are driven to move, so that the slider 11 moves retractably under the action of the receiving plate 16 and the spring 17. This achieves the effect of facilitating the removal of the outer frame 4 and the filter plate 5 from the connection frame 2 for cleaning, improving the positioning stability between the outer frame 4 and the connection frame 2, and also being able to limit the outer frame 4 to prevent the outer frame 4 from easily falling off from the inside of the connection frame 2, and facilitating the complete removal of the outer frame 4 and the filter plate 5 from the inside of the connection frame 2 for replacement, thus solving the problem of low stability of the filter element of the existing ventilation duct.

[0043] It should be noted that handwheels are provided on the outer circumferential surfaces of the first lead screw 6 and the second lead screw 13, which facilitates the control of the first lead screw 6 and the second lead screw 13 respectively through the handwheels.

[0044] The working principle of the above embodiment is as follows:

[0045] When the filter plate 5 needs to be cleaned, rotate the first lead screw 6 to drive the positioning rod 7 to move outward, so that the positioning rod 7 moves out of the positioning hole 8. Then, the outer frame 4 and the filter plate 5 can be removed from the inside of the connection frame 2. During the movement of the outer frame 4, the slider 11 will slide inside the limiting groove 12. When the filter plate 5 is completely removed from the connection frame 2, the limiting groove 12 will limit the slider 11 to prevent the outer frame 4 from falling off from the inside of the connection frame 2. When the outer frame 4 and the filter plate 5 need to be replaced, rotate the second lead screw 13 to drive the push plate 15 to move back through the threaded tube 14. The slider 11 moves back into the inside of the outer frame 4 under the pulling force of the spring 17 and moves out of the limiting groove 12 of the slider 11, no longer limiting the outer frame 4. Then, the outer frame 4 and the filter plate 5 can be directly removed for replacement.
