Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a range hood cleaning mechanism. Background Technology

[0002] A range hood cleaning system is a device specifically designed for cleaning range hoods. It can remove accumulated grease and stains, keep the range hood clean, improve its performance, reduce oil fume residue, and maintain fresh air in the kitchen.

[0003] During routine cleaning of range hoods, the dim lighting inside makes it difficult for workers to see the deep layers of grease, prolonging cleaning time and increasing the risk of missing areas. Traditional cleaning methods often fail to fully cover the complex internal structure of the range hood with cleaning tools, resulting in grease residue in some areas and ineffective cleaning. Furthermore, during cleaning, wastewater can easily splash onto the range hood's light covers, and long-term accumulation can affect the light transmittance of the covers, shortening their lifespan and interfering with the lighting for subsequent cleaning.

[0004] In view of this, this application proposes a range hood cleaning mechanism. Utility Model Content

[0005] The purpose of this application is to provide a range hood cleaning mechanism that solves the technical problems mentioned in the background art.

[0006] This application provides a range hood cleaning mechanism, including an extension water pipe, a rotating pipe head rotatably connected to the upper end of the extension water pipe, a spraying component at one end of the rotating pipe head, a fixing block above the spraying component, a lamp cover fixedly connected to the upper end of the fixing block, and an LED light fixedly connected inside the lamp cover.

[0007] The spraying assembly includes a connecting pipe that is fixedly connected to and communicates with a rotating pipe head. Both ends of the connecting pipe are fixedly connected to connecting extension pipes. The upper end of the extension pipe is rotatably connected to a rotating sleeve. A pair of connecting spraying plates are symmetrically fixedly connected to the outer wall of the rotating sleeve.

[0008] Optionally, a first fixing frame is fixedly connected to the upper part of the inside of the extended water pipe, a first rotating rod is rotatably connected through the inside of the first fixing frame, a first fan blade is fixedly connected to the lower end of the first rotating rod, and the upper end of the first rotating rod extends into the connecting pipe and is fixedly connected to the connecting pipe.

[0009] Optionally, a bearing ring is fixedly connected to the lower part of the outer wall of the rotating pipe head, and the outer ring of the bearing ring is fixedly connected to the inner wall of the extension water pipe, and the connecting pipe is fixedly connected to the fixing block.

[0010] Optionally, a second fixing frame is fixedly connected to the upper part of the inside of the extension tube, and a second rotating rod is rotatably connected through the inside of the second fixing frame.

[0011] Optionally, the upper end of the second rotating rod extends into the rotating sleeve and is fixedly connected to the rotating sleeve, and the lower end of the second rotating rod is fixedly connected to a second fan blade.

[0012] Optionally, the lower end of the extended water pipe is fixedly fitted with a threaded sleeve.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] This application provides clear lighting for staff by turning on the LED lights, allowing them to easily observe the scene deep inside the range hood. This effectively solves the problem of limited vision caused by insufficient light during cleaning, enabling staff to more accurately locate the oil stains and providing a good foundation for subsequent cleaning operations.

[0015] The water flow impacts the first blade, causing the rotating head, connecting pipe, extension pipe, and rotating sleeve to rotate synchronously. Simultaneously, the water flow impacts the second blade inside the extension pipe, causing the second rotating rod to drive the rotating sleeve and spray plate to rotate. This allows the spray plate to rotate on its own axis while simultaneously revolving around the central axis, significantly expanding the spray range. This not only ensures complete coverage of the range hood's interior, eliminating blind spots, but also more effectively removes grease, improving cleaning efficiency and quality. The rotation of the sleeve allows the water sprayed from the spray plate to pass over the lampshade, cleaning it. This effectively prevents wastewater from accumulating on the lampshade surface, avoiding issues that could affect lighting performance due to lampshade contamination, extending the lampshade's lifespan, and ensuring stable and reliable lighting during subsequent cleaning.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-3 This application provides a range hood cleaning mechanism, including an extension water pipe 1. A rotating pipe head 3 is rotatably connected to the upper end of the extension water pipe 1. A spraying component 4 is provided at one end of the rotating pipe head 3. A fixing block 5 is provided above the spraying component 4. A lamp cover 6 is fixedly connected to the upper end of the fixing block 5. An LED light 7 is fixedly connected inside the lamp cover 6. By turning on the LED light 7, clear lighting can be provided for the staff, making it easier for them to observe the scene deep inside the range hood. This effectively solves the problem of limited vision caused by insufficient light during cleaning, allowing the staff to more accurately find the location of the oil stains, and providing a good foundation for subsequent cleaning operations.

[0022] The spraying assembly 4 includes a connecting pipe 401 that is fixedly connected to and communicates with the rotating pipe head 3. Both ends of the connecting pipe 401 are fixedly connected to the connecting extension pipes 402. The upper end of the extension pipe 402 is rotatably connected to the rotating sleeve 403. A pair of connected spraying plates 404 are symmetrically fixedly connected to the outer wall of the rotating sleeve 403. The upper part of the extension pipe 1 is fixedly connected to the first fixed frame 8. The first rotating rod 9 is rotatably connected through the inside of the first fixed frame 8. The lower end of the first rotating rod 9 is fixedly connected to the first fan blade 10. The upper end of the first rotating rod 9 extends into the connecting pipe 401 and is fixedly connected to the connecting pipe 401. The water flow impacts the first fan blade 10, causing the rotating pipe head 3, the connecting pipe 401, the extension pipe 402 and the rotating sleeve 403 to rotate synchronously.

[0023] A second fixing bracket 405 is fixedly connected to the upper part of the extension pipe 402. A second rotating rod 406 is rotatably connected through the interior of the second fixing bracket 405. The upper end of the second rotating rod 406 extends into the rotating sleeve 403 and is fixedly connected to the rotating sleeve 403. A second fan blade 407 is fixedly connected to the lower end of the second rotating rod 406. The water flow impacts the second fan blade 407 inside the extension pipe 402, causing the second rotating rod 406 to drive the rotating sleeve 403 and the spray plate 404 to rotate. This allows the spray plate 404 to rotate on its own axis while revolving around the central axis, greatly expanding the spray range of clean water. This not only comprehensively covers and cleans the interior of the range hood, ensuring no cleaning dead corners, but also more effectively removes grease, improving cleaning effect and quality.

[0024] The rotation of the rotating sleeve 403 allows the clean water sprayed from the spray plate 404 to pass over the lamp cover 6 and clean it. This effectively prevents wastewater from covering the surface of the lamp cover 6, avoids the problem of affecting the lighting effect due to surface contamination of the lamp cover 6, extends the service life of the lamp cover 6, and ensures the stability and reliability of lighting in subsequent cleaning work.

[0025] A bearing ring 11 is fixedly connected to the lower part of the outer wall of the rotating pipe head 3, and the outer ring of the bearing ring 11 is fixedly connected to the inner wall of the extension water pipe 1. The connecting pipe 401 is fixedly connected to the fixing block 5. A threaded sleeve 2 is fixedly sleeved at the lower end of the extension water pipe 1. The bearing ring 11 provides good lubrication, making the rotating pipe head 3 rotate more smoothly.

[0026] Working principle: The operator installs the threaded sleeve 2 of the extension water pipe 1 onto the water pump. When it is necessary to clean the deep oil stains of the range hood, the LED light 7 is turned on so that the operator can observe the scene deep inside the range hood. The water pump sends water through the extension water pipe 1 into the rotating pipe head 3 and the connecting pipe 401. The water flow impacts the first fan blade 10 inside the extension water pipe 1 and drives the first fan blade 10 to rotate. The rotation of the first fan blade 10 drives the rotating pipe head 3 and the connecting pipe 401 to rotate synchronously. The rotation of the connecting pipe 401 drives the extension pipe 402 and the rotating sleeve 403 to rotate synchronously. Clean water enters the extension pipe 402 through the connecting pipe 401, and then enters the rotating sleeve 403 through the extension pipe 402. The rotating sleeve 403 delivers the clean water into the spray plate 404, and the spray plate 404 sprays the water out. As clean water flows through the extension pipe 402, the water flow impacts the second blade 407 inside the extension pipe 402, causing the second blade 407 to rotate. The rotation of the second blade 407 drives the second rotating rod 406 to rotate, which in turn drives the rotating sleeve 403 and the spray plate 404 to rotate synchronously. The rotating sleeve 403 and the spray plate 404 rotate automatically while revolving around the rotating sleeve 403, allowing the spray plate 404 to spray clean water over a wider area, thus fully covering and cleaning the interior of the range hood. Simultaneously, the rotation of the rotating sleeve 403 allows the clean water sprayed from the spray plate 404 to pass through the lampshade 6, cleaning it and preventing wastewater from accumulating on its surface and affecting its lighting effect. After cleaning is complete, the water pump can be turned off.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
