[0002] Chinese patent application CN202010757661.4 discloses a dust removal device for air ducts. This device uses a pull rope to move a dust removal hopper within the air duct, scraping dust from the duct into the hopper via its tangential edge. The hopper then removes the dust, overcoming the hazards, cumbersome nature, and incompleteness of existing air duct cleaning techniques, and eliminating the need to disassemble the air duct for cleaning. This significantly improves the efficiency and convenience for maintenance technicians. However, this device cannot intercept and remove impurities carried in the airflow during duct ventilation, causing these impurities to enter the room with the airflow, greatly reducing indoor air quality.

[0003] Furthermore, existing air ducts cannot reduce the noise of the airflow inside during normal use or cleaning, resulting in noise pollution. This noise is particularly annoying in relatively quiet working environments, making it difficult for people to concentrate on their work. Summary of the Invention

[0009] Preferably, the interception system includes an air hood and a filter screen; an air hood for guiding airflow is fixedly connected to the inner side of the annular scraper; and a filter screen for intercepting oil and impurities is fixedly connected to the rear side of the air hood.

[0010] Preferably, the inner wall of the air hood is provided with grooves for disturbing the airflow.

[0011] Preferably, the interception system also includes a rotating ring and blades; the rotating ring is rotatably connected inside the air duct; and blades for cleaning oil and impurities from the filter screen are fixed to the rotating ring.

[0012] Preferably, it also includes an airlock; an airlock for stabilizing airflow is fixedly connected inside the duct; an outward-curving part is provided on the front side of the airlock; the outward-curving part is located above the waste discharge hole.

[0013] Preferably, the inner wall of the airlock has several second recesses for noise reduction; the several second recesses form a golf ball surface structure on the inner wall of the airlock.

[0014] Preferably, it also includes protrusions; several protrusions are fixed to the inner wall of the pipe for vibrating to clean oil and impurities on the annular scraper; the protrusions are all located on the outer side of the outward-facing portion.

[0015] The beneficial effects of the present invention are: the present invention enables the airflow entering the duct to be guided to the inner wall of the duct through the air guide, which helps to reduce the oil and impurities transmitted into the room through the duct;

[0016] The golf ball-shaped structure formed by several first recesses reduces the range of the air guide's wake, which helps to reduce the resistance when the air guide moves backward. At the same time, it helps to reduce the noise generated when the airflow passes through the air guide.

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figures 2-4 As shown, a multi-functional air duct based on golf ball surface for noise reduction and wind resistance reduction includes a pipe 1 and a flange 2; an air inlet 1001 is provided on the pipe 1; the flange 2 is located at the air inlet 1001;

[0039] It also includes an adjusting component, an annular scraper 3, an air guide 4, a collection box 5, a spray pipe 7, and an interception system; the adjusting component is installed inside the pipe 1; the annular scraper 3 is installed on the adjusting component; the annular scraper 3 is made of an elastic and deformable material; the air guide 4 is installed inside the annular scraper 3; the front and rear of the air guide 4 are both conical, which is beneficial for guiding the airflow; several first recesses 4001 are opened on the rear surface of the air guide 4; the several first recesses 4001 form a golf ball surface structure on the rear surface of the air guide 4, which is beneficial for reducing the resistance when the air guide 4 moves; a waste discharge hole 1 is opened on the pipe 1. 002; A collection box 5 is provided on the outside of the pipe 1; the collection box 5 is located below the waste discharge hole 1002; a spray pipe 7 is provided inside the pipe 1; the spray pipe 7 is located above the waste discharge hole 1002; an interception system is provided on the inside of the annular scraper 3; the airflow entering the pipe 1 is guided to the inner wall of the pipe 1 by the air guide 4, which helps to reduce the oil and dirt impurities transmitted into the room through the pipe 1; the golf ball surface structure formed by several first recesses 4001 reduces the wake range of the air guide 4, which helps to reduce the resistance when the air guide 4 moves backward, and at the same time, helps to reduce the noise generated when the airflow passes through the air guide 4.

[0040] The adjusting assembly includes a connecting block 101 and an elastic element 102; two vertically symmetrical sliding grooves 1003 are opened inside the pipe 1; two vertically symmetrical connecting blocks 101 are slidably arranged inside the pipe 1; each connecting block 101 is located in the corresponding sliding groove 1003; the two connecting blocks 101 are fixedly connected to the outside of the annular scraper 3; two vertically symmetrical elastic elements 102 are fixedly connected inside the pipe 1, and the elastic elements 102 are springs; each elastic element 102 is located in the corresponding sliding groove 1003 and is fixedly connected to the adjacent connecting block 101.

[0041] The rear part of the annular scraper 3 is provided with a raised part 3001; the raised part 3001 disturbs the airflow passing through the annular scraper 3, thereby reducing the range of the wake of the annular scraper 3, which helps to reduce the resistance when the annular scraper 3 moves backward.

[0042] It also includes guide plates 6; several guide plates 6 for guiding airflow are fixed to the arc-shaped part of the upper inner wall of the pipe 1; several ventilation holes are opened on the surface of each guide plate 6; the airflow passing through the arc-shaped part of the pipe 1 is guided in layers by the guide plates 6 to prevent the airflow from colliding with the outer arc side of the arc-shaped part of the pipe 1, which helps to reduce the noise at the arc-shaped part of the pipe 1.

[0043] The specific process of noise reduction in this invention is as follows:

[0044] When airflow enters the duct 1 through the air inlet 1001, the airflow first contacts the front of the air guide 4. The air guide 4 guides the airflow into the duct 1 towards the inner wall of the duct 1, causing the oil and impurities carried in the airflow to adhere to the inner wall of the duct 1. This helps reduce the amount of oil and impurities transmitted into the room through the duct 1. When the airflow is weak, it cannot push the annular scraper 3 away from the rear of the air guide 4. The outer side of the annular scraper 3 adheres to the inner wall of the duct 1. The airflow pushes the air guide 4 and the annular scraper 3 backward within the duct 1, simultaneously compressing the elastic element 102. The annular scraper 3 then scrapes the oil and impurities adhering to the inner wall of the duct 1 to the exhaust hole 1002, allowing the oil and impurities to flow in. Inside the collection box 5, the cleanliness of the pipe 1 is ensured. When the air guide 4 drives the annular scraper 3 to move backward in the pipe 1, the golf ball-shaped structure formed by several first recesses 4001 creates a turbulent boundary layer that adheres tightly to the rear of the air guide 4. This causes the airflow to form vortices in each first recess 4001, increasing the distance the airflow travels along the rear of the air guide 4 and reducing the range of the air guide 4's wake. This reduces the pressure at the rear of the air guide 4, which helps reduce the resistance when the air guide 4 moves backward and enhances the cleaning effect of the annular scraper 3 on the inner wall of the pipe 1. At the same time, it helps reduce the noise generated when the air flows in the pipe 1.

[0045] When the airflow is strong, the airflow pushes the annular scraper 3 open to the rear of the guide vane 4. At this time, the outer side of the annular scraper 3 separates from the inner wall of the pipe 1. The airflow pushes the guide vane 4 and the annular scraper 3 to move backward in the pipe 1. At the same time, it compresses the elastic element 102 and disturbs the airflow between the annular scraper 3 and the inner wall of the pipe 1 through the raised part 3001. This causes a turbulent boundary layer to be formed on the rear side of the annular scraper 3, which is close to the rear of the annular scraper 3. This causes the airflow to form a vortex at the raised part 3001, increasing the distance the airflow travels when passing through the annular scraper 3. This reduces the range of the wake of the annular scraper 3, which helps to reduce the resistance when the annular scraper 3 moves backward. At the same time, it helps to reduce the noise generated when the airflow passes between the annular scraper 3 and the inner wall of the pipe 1.

[0046] When the air guide 4 moves the annular scraper 3 to the waste discharge hole 1002, the cleaning liquid is sprayed onto the outside of the annular scraper 3 through the spray pipe 7. When the air supply to the pipe 1 stops, the air guide 4 loses the thrust of the airflow and is reset by the elastic element 102, thereby driving the annular scraper 3 to perform a secondary scraping of the inner wall of the pipe 1, further enhancing the cleaning effect of the annular scraper 3 on the inner wall of the pipe 1. When the airflow passes through the inner arc of the pipe 1, the airflow passing through the inner arc of the pipe 1 is guided in layers by the guide plate 6, reducing the impact force of the airflow on the outer arc side of the inner arc of the pipe 1. At the same time, through several ventilation holes on the surface of the guide plate 6, the areas separated by each guide plate 6 are connected to each other, further preventing the airflow from colliding with the outer arc side of the inner arc of the pipe 1, which helps to reduce the noise at the inner arc of the pipe 1.

[0047] Example 2

[0048] Based on Example 1, such as Figures 5-8 As shown, the interception system includes an air hood 201 and a filter screen 202; the air hood 201 is fixedly connected to the inner side of the annular scraper 3; the filter screen 202 is fixedly connected to the rear side of the air hood 201; the air hood 201 guides the airflow between the outermost part of the air guide 4 and the air hood 201 to the filter screen 202, and the filter screen 202 intercepts the oil and dirt impurities carried in the airflow, further reducing the oil and dirt impurities transmitted into the room through the pipe 1.

[0049] The inner wall of the air hood 201 has a groove 20101; the groove 20101 causes the airflow passing through the inner wall of the air hood 201 to form turbulence, which increases the contact area between the airflow and the filter screen 202 and improves the interception effect of the filter screen 202 on oil and impurities.

[0050] The interception system also includes a rotating ring 203 and blades 204; the rotating ring 203 is rotatably connected inside the air duct 201; blades 204 are fixedly connected to the rotating ring 203; the airflow drives the blades 204 to rotate, thereby scraping off the oil and impurities attached to the filter screen 202, preventing the filter screen 202 from being blocked by oil and impurities, and avoiding the inability of airflow to flow normally.

[0051] The specific process of intercepting oil pollution according to this invention is as follows:

[0052] Because the gap between the outermost part of the air guide 4 and the air hood 201 is small, when the airflow enters the air hood 201 along the air guide 4, the gas velocity increases, and the oil and dirt impurities carried in the airflow quickly adhere to the filter screen 202. The filter screen 202 intercepts the oil and dirt impurities carried in the airflow, further reducing the amount of oil and dirt impurities transmitted into the room through the pipe 1. When the airflow enters the air hood 201, the airflow passing through the inner wall of the air hood 201 forms a vortex in the groove 20101. This increases the airflow range within the hood 201, thereby increasing the contact area between the airflow and the filter screen 202 and improving the filter screen 202's ability to intercept oil and impurities. Simultaneously, the airflow within the hood 201 causes the rotating ring 203 to drive the blades 204 to rotate within the hood 201, scraping off the oil and impurities attached to the filter screen 202. The scraped-off oil and impurities fall into the collection box 5 through the waste discharge hole 1002, preventing the filter screen 202 from being blocked by oil and impurities and ensuring normal airflow.

[0053] Example 3

[0054] Based on Example 1, such as Figure 1 , Figure 9 and Figure 10As shown, it also includes a shut-off valve 301; the shut-off valve 301 is fixedly connected inside the pipe 1; the shut-off valve 301 has an outward-turned part 30101 on the front side; the outward-turned part 30101 is located above the waste discharge hole 1002; the shut-off valve 301 stabilizes the airflow passing through the air duct 201, preventing the airflow from expanding when it leaves the rear side of the air duct 201, and avoiding the expanded airflow from impacting the inner wall of the pipe 1, which would increase noise.

[0055] The inner wall of the airlock 301 has several second recesses 30102; the several second recesses 30102 form a golf ball surface structure on the inner wall of the airlock 301; by reducing the range of the wake passing through the airlock 301 through the several second recesses 30102, it is beneficial to reduce the noise generated when the airflow passes through the airlock 301.

[0056] It also includes protrusions 302; several protrusions 302 arranged in a ring are fixed to the inner wall of the pipe 1; several protrusions 302 are located on the outside of the outwardly turned part 30101; the protrusions 302 cause the oil and dirt on the ring scraper 3 to be shaken off into the collection box 5, ensuring the continuous cleaning effect of the ring scraper 3.

[0057] The specific process of current stabilization and noise reduction in this invention is as follows:

[0058] When the airflow pushes the air guide 4 and the annular scraper 3 to move backward in the pipe 1 to the position of the airlock 301, the rear part of the air hood 201 enters the airlock 301. At the same time, the raised part 3001 is fastened to the outwardly turned part 30101 to fix the air guide 4 and the air hood 201. At this time, the outer side of the annular scraper 3 is attached to the inner wall of the pipe 1. The airflow enters the airlock 301 through the air hood 201. The airlock 301 stabilizes the airflow passing through the air hood 201 to prevent the airflow from expanding when it leaves the rear side of the air hood 201. This avoids the expanded airflow impacting the inner wall of the pipe 1 and causing increased noise. At the same time, the golf ball-shaped structure formed by several second recesses 30102 causes the airflow to form a vortex in each second recess 30102, increasing the distance the airflow moves along the inner wall of the airlock 301 and reducing the range of the wake of the airlock 301. This helps to reduce the noise generated when the airflow passes through the airlock 301.

[0059] When the annular scraper 3 moves to the position of the protrusion 302, the protrusion 302 causes the annular scraper 3 to vibrate, shaking the oil and impurities on the annular scraper 3 into the collection box 5, thus ensuring the continuous cleaning effect of the annular scraper 3.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
