Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning equipment, specifically a cleaning device for oil fume pipelines. Background Technology

[0002] In modern home kitchens and restaurants, the exhaust duct of the range hood serves as a crucial channel for the discharge of cooking fumes, and the cleanliness of its outer walls directly affects the kitchen's fire safety and environmental hygiene. Because cooking fumes contain a large amount of grease, it gradually adheres to the outer wall of the duct during the exhaust process, forming stubborn grease buildup. This grease not only breeds bacteria and emits unpleasant odors, but also poses a significant fire hazard. If it comes into contact with an open flame, it can easily cause a fire, threatening life and property. In practical applications, range hood exhaust ducts are often installed against the wall, making the cleaning space for the wall-mounted section of the duct extremely limited. Even when using ordinary long-handled brushes, steel wool, and cleaning agents for manual cleaning, operators often struggle to apply force due to the limited space and the difficulty in adjusting the tools to the appropriate angle, making it particularly difficult to clean the grease on the back of the duct.

Detailed Implementation

[0012] Example 1 like Figures 1 to 3As shown, a cleaning device for kitchen exhaust ducts includes a telescopic handle 1, a brush head 2, and a wire brush 3. One end of the wire brush 3 is fixed to one end of the telescopic handle 1, and the other end is connected to the side wall of the telescopic handle 1. The brush head 2 is rotatably mounted on the other end of the telescopic handle 1, with its rotation axis perpendicular to the telescopic handle 1. Several wire bristles 4 are densely fixed on the brush head 2. Both ends of the telescopic handle 1 can be used; the end with the brush head 2 cleans the front of the duct, and the end with the wire brush 3 cleans the back of the duct (the part closest to the wall). The steel wire bristles 4 on the brush head 2 scrape off the oil and impurities attached to the pipe. When cleaning the back of the pipe, remove one end of the steel wire brush cloth 3 connected to the side wall of the telescopic handle 1, wrap the steel wire brush cloth 3 around the fume duct, and then connect the steel wire brush cloth 3 to the telescopic handle 1 so that the steel wire brush cloth 3 forms a ring after wrapping the pipe, so that the steel wire brush cloth 3 can wrap the back of the fume duct. By repeatedly dragging the steel wire brush cloth 3 up and down, the steel wire brush cloth 3 can clean the back of the fume duct. The pipe cleaning operation can be completed in a small space, ensuring that the oil stains on the part of the pipe near the wall are cleaned.

[0013] Example 2 Based on Example 1, such as Figure 1 and Figure 2 As shown, the telescopic handle 1 includes a first rod 11 and a second rod 12. One end of the first rod 11 is provided with a sliding groove 13, and one end of the second rod 12 is slidably fitted into the sliding groove 13. By moving the second rod 12, the length of the telescopic handle 1 can be adjusted so as to reasonably adjust the length of the telescopic handle 1 according to the arrangement distance between the pipe and the countertop, so that the wire brush cloth 3 and the brush head 2 of the telescopic handle 1 can smoothly act on the pipe for cleaning operations.
