Description

Technical Field

[0001] This utility model relates to the field of flue cleaning, and in particular to a flue structure that can be automatically cleaned. Background Technology

[0002] As a crucial structure for smoke extraction in industrial exhaust systems and other applications, flues tend to accumulate grease, dust, and other debris on their inner walls over time. If not cleaned promptly, this can not only affect smoke extraction efficiency but also lead to blockages, bacterial growth, and even fire hazards. Currently, most common flue structures on the market require regular manual disassembly and cleaning.

[0003] In existing technologies, operators must first disassemble the outer casing of the flue to expose the inner wall of the flue cavity, and then remove the attached materials by manual scraping and rinsing. After cleaning, the flue is reassembled. This manual disassembly and cleaning method is cumbersome and inefficient: the disassembly and assembly process of the flue consumes a lot of time and manpower, especially for flue systems with complex layouts or long distances. The disassembly steps are complicated, resulting in a long cleaning cycle and seriously affecting the normal operating efficiency of the smoke exhaust system.

[0004] Based on this, we propose a self-cleaning flue structure. Utility Model Content

[0005] To address the technical problem of inconvenient disassembly for manual cleaning of flues, this utility model provides a flue structure that can be automatically cleaned.

[0006] This utility model is achieved by the following technical solution: an automatically cleanable flue structure, including a flue shell, a flue cavity formed inside the flue shell, an outer wall cleaning mechanism and a pull-out cleaning mechanism installed inside the flue shell, and automatic cleaning of the inner wall of the flue cavity is achieved through the cooperation of the outer wall cleaning mechanism and the pull-out cleaning mechanism inside the flue shell.

[0007] The external wall cleaning mechanism includes a mounting bracket, which is embedded in the bottom of the flue shell. A clip bracket is fixedly mounted on the mounting bracket, and an ear plate is fixedly connected to the bottom end of the bracket. A fixing bolt passes through the inner thread of the ear plate. The surface of the mounting bracket has slots, and a mounting sleeve is installed inside the slots. A limit sleeve, made of rubber and shaped like a raised arch, is fixedly connected to the outer surface of the mounting sleeve. The slots on the mounting bracket surface engage with the raised arch of the limit sleeve. A handle is fixedly connected to the outer side of the mounting sleeve, and a connecting frame is fixedly connected to the end of the mounting sleeve away from the handle. A support beam is fixedly mounted on the surface of the connecting frame, and scrapers are fixedly connected to both ends of the support beam. The scrapers form a closed "U" shape. Multiple sets of scrapers are provided, and the scrapers adhere to the inner wall of the flue cavity.

[0008] The pull-out cleaning mechanism includes a handle, with a pull-out base plate fixedly connected to the outside of the handle. The pull-out base plate is located at the bottom end of the flue cavity, above the supporting crossbeam, and its width is smaller than the width of the supporting crossbeam.

[0009] As a further optimization of this utility model, the outer wall cleaning mechanism uses a scraper to scrape and clean the inner wall of the flue cavity, while the pull-out cleaning mechanism is used to collect and discharge the debris generated during the cleaning process. The two work together to reduce manual intervention.

[0010] As a further optimization of this utility model, the mounting bracket of the outer wall cleaning mechanism is embedded in the bottom of the flue shell and fixed by ear plates and fixing bolts. The buckle bracket is used to assist in positioning the mounting bracket and ensure the stability of the mechanism.

[0011] As a further optimization of this utility model, the operator pulls the mounting sleeve by gripping the handle. The mounting sleeve drives the connecting frame and the support beam to move within the slot of the mounting bracket, causing the scrapers at both ends to slide along the inner wall of the flue cavity. The limiting sleeve is made of rubber, and its raised arched strip structure fits into the slot of the mounting bracket, ensuring the stability of the mounting sleeve and preventing it from shaking when not in use.

[0012] As a further optimization of this utility model, by reciprocatingly pulling the handle, the oil stains and debris inside the flue can be thoroughly scraped, solving the problem of cleaning dead corners in traditional fixed scrapers; the scraped oil stains and impurities are scraped to the outlet of the flue cavity for easy collection by workers.

[0013] As a further optimization of this utility model, after the scraper scrapes the debris on the top of the flue and some of the debris on the side wall to the bottom of the flue cavity, the operator can pull out the bottom plate by pulling out the handle. The debris on the bottom plate is moved out of the flue shell along with the bottom plate. The debris can be cleaned without disassembling the main body of the flue, which solves the problem of the traditional structure requiring manual disassembly of the bottom plate.

[0014] As a further optimization of this utility model, a long strip groove is provided at the bottom of the flue shell, and a pull-out bottom plate passes through the groove at the bottom of the flue shell and extends into the flue cavity. The other end of the pull-out bottom plate extends into the long strip groove at the other end of the flue cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves internal wall cleaning by linking the outer wall cleaning mechanism and the pull-out cleaning mechanism, without disassembling the flue shell. The operator only needs to pull the handle to drive the scraper to scrape, and then pull out the bottom plate to discharge the debris, which greatly reduces the manual disassembly and assembly steps.

[0017] 2. The utility model forms a closed "mouth" shape by multiple scraping plates and fits them to the inner wall of the flue cavity. By reciprocally pulling the grip, the entire inner wall of the flue can be covered, avoiding the cleaning blind spots of traditional fixed scraping plates and ensuring the complete scraping of oil stains and sundries.

[0018] 3. The convex arched strip structure of the limit collar of the utility model is engaged with the slot of the mounting bracket to prevent the mounting sleeve from shaking, ensuring that the scraping plate stably fits the inner wall during movement and avoiding the loosening of components in the non-working state.

[0028] Next, in combination with the drawings and specific embodiments, the utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0029] Embodiment 1:

[0030] Please combine Figures 1-7 This embodiment proposes an automatically cleanable flue structure, including a flue shell 1, with a flue cavity 2 formed inside the flue shell 1. An outer wall cleaning mechanism 3 and a pull-out cleaning mechanism 4 are installed inside the flue shell 1. Through the cooperation of the outer wall cleaning mechanism 3 and the pull-out cleaning mechanism 4 inside the flue shell 1, automatic cleaning of the inner wall of the flue cavity 2 is achieved. The outer wall cleaning mechanism 3 uses a scraper 310 to scrape and clean the inner wall of the flue cavity 2, while the pull-out cleaning mechanism 4 is used to collect and discharge debris generated during the cleaning process. The two mechanisms work together to reduce manual intervention.

[0031] The outer wall cleaning mechanism 3 includes a mounting bracket 31, which is embedded in the bottom of the flue housing 1. A snap-fit ​​bracket 32 ​​is fixedly mounted on the mounting bracket 31, and an ear plate 33 is fixedly connected to the bottom end of the mounting bracket 31. A fixing bolt 34 passes through the inner thread of the ear plate 33. The mounting bracket 31 of the outer wall cleaning mechanism 3 is embedded in the bottom of the flue housing 1 and fixed by the ear plate 33 and the fixing bolt 34. The snap-fit ​​bracket 32 ​​is used to assist in positioning the mounting bracket 31 to ensure the stability of the mechanism.

[0032] The surface of the mounting bracket 31 has a slot, and the mounting sleeve 35 is installed inside the slot. The outer ring surface of the mounting sleeve 35 is fixedly connected to a limiting sleeve 37. The limiting sleeve 37 is made of rubber and has a raised arched strip shape. The slot on the surface of the mounting bracket 31 fits into the raised arched strip shape of the limiting sleeve 37.

[0033] A handle 36 is fixedly connected to the outer side of the mounting sleeve 35. A connecting frame 38 is fixedly connected to the end of the mounting sleeve 35 away from the handle 36. A support beam 39 is fixedly mounted on the surface of the connecting frame 38. Scrapers 310 are fixedly connected to both ends of the support beam 39. The scrapers 310 form a closed U-shape. Multiple sets of scrapers 310 are provided, and the scrapers 310 are attached to the inner wall of the flue cavity 2.

[0034] The specific technical solution involves the operator pulling the mounting sleeve 35 using the handle 36. The mounting sleeve 35 causes the connecting frame 38 and the support beam 39 to move within the slot of the mounting bracket 31, allowing the scrapers 310 at both ends to slide along the inner wall of the flue cavity 2. The limiting sleeve 37 is made of rubber, and its raised arched strip structure fits into the slot of the mounting bracket 31, ensuring the stability of the mounting sleeve 35 and preventing it from shaking when not in use.

[0035] The supporting beam 39 fits against the bottom wall, and multiple scrapers 310 fit against the inner wall of the flue cavity 2, covering different areas. By reciprocatingly pulling the handle 36, the oil stains and debris on the inner wall of the flue can be thoroughly scraped, solving the problem of cleaning dead corners with traditional fixed scrapers. The scraped oil stains and debris are scraped to the outlet of the flue cavity 2 for easy collection by workers.

[0036] The pull-out cleaning mechanism 4 includes a handle 41, and a pull-out base plate 42 is fixedly connected to the outside of the handle 41. The pull-out base plate 42 is located at the bottom end of the flue cavity 2 and is located above the support beam 39. The width of the pull-out base plate 42 is smaller than the width of the support beam 39.

[0037] It should be noted that a long groove is provided at the bottom of the flue shell 1, and the pull-out bottom plate 42 passes through the groove at the bottom of the flue shell 1 and extends to the flue cavity 2. The other end of the pull-out bottom plate 42 extends into the long groove at the other end of the flue cavity 2.

[0038] More specifically, after the scraper 310 scrapes the debris from the top of the flue and some debris from the side wall to the bottom of the flue cavity 2, the operator pulls out the bottom plate 42 by the handle 41. The debris on the bottom plate is moved out of the flue shell 1 along with the bottom plate. The debris can be cleaned without disassembling the main body of the flue, which solves the problem of the traditional structure requiring manual disassembly of the bottom plate.

[0039] Working principle

[0040] I. Principle of Overall Structural Coordination

[0041] The automatic cleaning of the inner wall of the flue cavity 2 is achieved through the cooperation of the outer wall cleaning mechanism 3 and the pull-out cleaning mechanism 4 inside the flue shell 1. The outer wall cleaning mechanism 3 uses a scraper 310 to scrape and clean the inner wall of the flue cavity 2, while the pull-out cleaning mechanism 4 is used to collect and discharge the debris generated during the cleaning process. The two work together to reduce manual intervention.

[0042] II. Working Principle of External Wall Cleaning Mechanism

[0043] The mounting bracket 31 of the outer wall cleaning mechanism 3 is embedded in the bottom of the flue shell 1 and fixed by the ear plate 33 and the fixing bolt 34. The buckle bracket 32 ​​is used to assist in positioning the mounting bracket 31 to ensure the stability of the mechanism.

[0044] The operator pulls the mounting sleeve 35 using the handle 36. The mounting sleeve 35 moves the connecting frame 38 and the support beam 39 within the slot of the mounting bracket 31, causing the scrapers 310 at both ends to slide along the inner wall of the flue cavity 2. The limiting sleeve 37 is made of rubber, and its raised arched strip structure fits into the slot of the mounting bracket 31, ensuring the stability of the mounting sleeve 35 and preventing it from shaking when not in use.

[0045] Multiple scraper sets work together: the support beam 39 fits against the bottom wall, and multiple scraper sets 310 fit against the inner wall of the flue cavity 2, covering different areas. By reciprocatingly pulling the handle 36, the oil stains and debris on the inner wall of the flue can be thoroughly scraped, solving the problem of cleaning dead corners by traditional fixed scrapers. The scraped oil stains and impurities are scraped to the outlet of the flue cavity 2 for easy collection by workers.

[0046] III. Working Principle of the Pull-out Cleaning Mechanism

[0047] Structural configuration: The pull-out base plate 42 of the pull-out cleaning mechanism 4 is located at the bottom end of the flue cavity 2, and its width is smaller than that of the supporting crossbeam 39 to avoid interference with the outer wall cleaning mechanism 3. The two ends of the pull-out base plate 42 penetrate the long strip groove at the bottom end of the flue shell 1, and can be pulled out laterally along the groove.

[0048] Collection and cleaning at the bottom of the flue cavity: After the scraper 310 scrapes the debris from the top of the flue and some debris from the side wall to the bottom of the flue cavity 2, the operator pulls out the bottom plate 42 by the handle 41. The debris on the bottom plate is moved out of the flue shell 1 along with the bottom plate. The debris can be cleaned without disassembling the main body of the flue, which solves the problem of the traditional structure requiring manual disassembly of the bottom plate.

[0049] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
