Description

Technical Field

[0001] This utility model relates to the field of ventilation duct technology, specifically to a self-cleaning ventilation duct for testing oil fume air. Background Technology

[0002] With increasing environmental awareness and ever-increasing requirements for air quality monitoring, fume air testing plays a crucial role in many fields, such as the regulation of fume emissions in the catering industry and air quality analysis in environmental science research. When conducting fume air testing, the ventilation duct, as a key component guiding the flow of fume air, directly affects the accuracy of the test results and the smooth progress of the entire testing process.

[0003] Because cooking fumes contain a large amount of grease, particulate matter, and other impurities, they easily adhere to the pipe walls when flowing through the ventilation duct. As the usage time increases, the grease will continue to accumulate. This accumulated grease will not only reduce the inner diameter of the ventilation duct and increase ventilation resistance, leading to poor ventilation and affecting the normal transport of cooking fume air, thus interfering with the accuracy of the data obtained by the testing instrument; it will also breed bacteria, emit unpleasant odors, and disrupt the stability of the testing environment, potentially having an adverse impact on the test results. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a self-cleaning ventilation pipe for testing oil fume air, comprising: a fixed pipe; a liquid storage component, the outer wall of which is fixedly connected to the inner wall of the fixed pipe, the liquid storage component being used to store cleaning liquid; a cleaning component, the outer wall of which is fixedly connected to the inner wall of the liquid storage component, the cleaning component being used to scrape the inner wall of the pipe by rotation; the cleaning component includes a support frame, the outer wall of which is rotatably connected to blades via a connecting ring, and the outer wall of the connecting ring being rotatably connected to the inner wall of the support frame; a brush rod is fixedly connected to the outer wall of the connecting ring via a connecting frame, the brush rod being arranged in a ring array along the central axis of the connecting ring, and the outer wall of the connecting frame being rotatably connected to the outer wall of the brush rod.

[0005] Preferably, the side of the connecting frame away from the brush rod is fixedly connected to the outer wall of the connecting ring, the outer wall of the connecting ring is fixedly connected to the outer wall of the blade, and the brush rod includes a rod body and brush bristles.

[0006] Preferably, the cleaning assembly includes an inner tube, an absorbent sponge is fixedly connected to the inner wall of the inner tube, and a fixing shell is fixedly connected to the inner wall of the inner tube, and the fixing shell is linearly arrayed along the central axis of the inner tube.

[0007] Preferably, a water-guiding pad is fixedly connected to the inner wall of the fixed shell, the water-guiding pad is linearly arrayed along the central axis of the fixed shell, a water-absorbing pad is fixedly connected to the bottom of the water-guiding pad, the outer wall of the water-absorbing pad is fixedly connected to the inner wall of the fixed shell, and the outer wall of the water-guiding pad is in contact with the outer wall of the brush rod.

[0008] Preferably, the outer wall of the absorbent pad is fixedly connected to the outer wall of the absorbent sponge, the outer wall of the inner tube is fixedly connected to the inner wall of the fixing tube, the inner wall of the fixing tube is fixedly connected to the outer wall of the absorbent sponge, the fixing tube restricts the position of the absorbent sponge, and a water inlet pipe is fixedly connected to the top of the fixing tube.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by incorporating a cleaning component and a liquid storage component, enables the ventilation duct to automatically clean itself during oil fume air testing, eliminating the need for frequent manual intervention. During normal operation, the cleaning component automatically activates with the flow of oil fume air, working in conjunction with the continuously supplied cleaning fluid from the liquid storage component to scrape and clean the duct walls. This saves labor costs and improves overall work efficiency, making it particularly suitable for scenarios involving long-term, continuous oil fume air testing.

[0011] 2. This utility model, by setting up a cleaning component, allows the blades to rotate using the airflow within the ventilation duct, thereby driving the connecting ring and the brush rod connected to it to move in a circular motion along the duct wall. This achieves the initial scraping and removal of impurities such as oil and dust. At the same time, the water-absorbing sponge, the fixed shell, and the water-guiding pad and absorbent pad inside the inner tube form a cleaning liquid conduction and storage system, ensuring that the brush rod can be dipped in the cleaning liquid. With the help of the chemical action of dissolving and emulsifying the cleaning liquid, the stubborn oil stains that are tightly attached are removed, ensuring that the inner wall of the ventilation duct can maintain a high degree of cleanliness and reducing the impact of oil accumulation on ventilation performance and the accuracy of test results.

[0019] Example:

[0020] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a self-cleaning ventilation pipe for testing oil fume air, comprising: a fixed pipe 1; a liquid storage component 3, the outer wall of which is fixedly connected to the inner wall of the fixed pipe 1, the liquid storage component 3 being used to store cleaning liquid; and a cleaning component 2, the outer wall of which is fixedly connected to the inner wall of the liquid storage component 3, the cleaning component 2 being used to scrape the inner wall of the pipe by rotation; the cleaning component 2 includes a support frame 31, the outer wall of which is rotatably connected to a blade 32 via a connecting ring 33, and the outer wall of the connecting ring 33 being connected to the inner wall of the support frame 31. The outer wall of the connecting ring 33 is fixedly connected to the brush rod 35 via the connecting frame 34, and the outer wall of the connecting frame 34 is rotatably connected to the outer wall of the brush rod 35. The side of the connecting frame 34 away from the brush rod 35 is fixedly connected to the outer wall of the connecting ring 33. The outer wall of the connecting ring 33 is fixedly connected to the outer wall of the blade 32. When there is oily smoke and air flowing in the ventilation pipe, the airflow will act on the blade 32. Due to the fixed connection between the blade 32 and the connecting ring 33, the force of the airflow will drive the blade 32 to rotate, thereby driving the connecting ring 33 to rotate around the support frame 31.

[0021] The cleaning component 2 includes an inner tube 21, with an absorbent sponge 22 fixedly connected to the inner wall of the inner tube 21. A fixing shell 23 is also fixedly connected to the inner wall of the inner tube 21, and the fixing shell 23 is arranged linearly along the central axis of the inner tube 21. The absorbent sponge 22 can absorb a certain amount of water or other liquids, and plays a role in temporarily storing and slowly releasing cleaning liquid during the cleaning process.

[0022] A water-guiding pad 24 is fixedly connected to the inner wall of the fixed shell 23. A water-absorbing pad 25 is fixedly connected to the bottom of the water-guiding pad 24. The outer wall of the water-absorbing pad 25 is fixedly connected to the inner wall of the fixed shell 23. The outer wall of the water-guiding pad 24 is in contact with the outer wall of the brush rod 35. The outer wall of the water-absorbing pad 25 is fixedly connected to the outer wall of the water-absorbing sponge 22. The outer wall of the inner tube 21 is fixedly connected to the inner wall of the fixed tube 1. The inner wall of the fixed tube 1 is fixedly connected to the outer wall of the water-absorbing sponge 22. The water-guiding pad 24 can receive water from the water-absorbing sponge 22. The cleaning fluid is drawn from the liquid storage component 3 and guided to flow to the required area. On the other hand, its bottom is connected to the absorbent pad 25. The absorbent pad 25 is not only tightly connected to the water guide pad 24, but also fixed to the absorbent sponge 22. In this way, the brush rod 35 will come into contact with the outer wall of the water guide pad 24 during the rotating and scraping process, so that it can pick up the cleaning fluid on the water guide pad 24. Meanwhile, the dirt remaining inside the inner tube 21 will be discharged from the inner tube 21 by the rotation of the brush rod 35.

[0023] Working principle:

[0024] The ventilation duct mainly consists of a fixed pipe 1, a liquid storage component 3, and a cleaning component 2. The fixed pipe 1 serves as the basic structure of the entire ventilation duct, providing stable support and housing space for the internal liquid storage component 3 and cleaning component 2. It also serves as the flow channel for oily fumes during the testing process. The liquid storage component 3 is fixed to the inner wall of the fixed pipe 1 and plays an important role in storing cleaning fluid, providing the necessary source of cleaning materials for the subsequent cleaning work of the cleaning component 2. The cleaning component 2 is located inside the liquid storage component 3. Through a specific mechanical structure and connection method, it achieves scraping and cleaning of the inner wall of the ventilation duct by rotation, thereby removing oil and other pollutants attached to the pipe wall.

[0025] The cleaning assembly 2 has a structure that works together to achieve the cleaning function. The support frame 31 is an important support part of the cleaning assembly 2, which provides a stable framework for the entire cleaning action. The connecting ring 33 plays a key role in the connection and rotation in this structure. Its outer wall is rotatably connected to the inner wall of the support frame 31, which allows the connecting ring 33 to rotate relative to the inner wall of the support frame 31. The blade 32 is fixedly connected to the outer wall of the connecting ring 33. When there is oily smoke and air flowing in the ventilation duct, the airflow will act on the blade 32. Due to the fixed connection between the blade 32 and the connecting ring 33, the force of the airflow will drive the blade 32 to rotate, which in turn will drive the connecting ring 33 to rotate around the support frame 31.

[0026] Meanwhile, the outer wall of the connecting ring 33 is also fixedly connected to the brush rod 35 through the connecting frame 34. The connecting frame 34 itself is also rotatably connected to the outer wall of the brush rod 35, so that it can better fit the inner wall of the ventilation duct. When the connecting ring 33 rotates, the brush rod 35 will move in a circle along the inner wall of the ventilation duct, just like a brush brushing on the duct wall, scraping and cleaning the oil, dust and other impurities attached to the duct wall, peeling them off from the duct wall, and achieving the effect of initially cleaning the duct wall.

[0027] In addition, the inner tube 21 in the cleaning assembly 2 also plays an important auxiliary cleaning role. The inner wall of the inner tube 21 is fixedly connected to an absorbent sponge 22, which can absorb a certain amount of water or other liquids and plays a role in temporarily storing and slowly releasing cleaning fluid during the cleaning process. The fixed shells 23, which are linearly arrayed along the central axis of the inner tube 21, also serve the cleaning function in their internal structure. The inner wall of the fixed shells 23 is fixedly connected to a water-guiding pad 24 and an absorbent pad 25 in sequence. The water-guiding pad 24 can receive liquid from the storage area. The cleaning fluid in component 3 is guided to flow to the required area. On the other hand, its bottom is connected to the absorbent pad 25. The absorbent pad 25 is not only tightly connected to the water guide pad 24, but also fixed to the absorbent sponge 22. In this way, the brush handle 35 will come into contact with the outer wall of the water guide pad 24 during the rotating scraping process, so that it can pick up the cleaning fluid on the water guide pad 24. When the brush handle 35 scrapes the tube wall, it can use the dissolving and emulsifying effects of the cleaning fluid to more effectively remove stubborn oil stains and further improve the cleaning effect.

[0028] The liquid storage component 3 serves as the storage unit for the cleaning liquid. It is fixedly installed on the inner wall of the fixed pipe 1. Its structural design aims to ensure that the cleaning liquid can be stored stably and to provide cleaning liquid to the cleaning component 2 as needed. When the cleaning component 2 needs to perform cleaning work, the cleaning liquid in the liquid storage component 3 will slowly flow to the corresponding part of the cleaning component 2 under gravity or other appropriate guidance. Through the connection with the water guide pad 24, the cleaning liquid is delivered to the water guide pad 24, thereby providing a source for the brush rod 35 to pick up the cleaning liquid. This ensures a continuous supply of cleaning liquid throughout the cleaning process, enabling the cleaning work of the cleaning component 2 to proceed smoothly and achieve the purpose of continuously and effectively cleaning the inner wall of the ventilation pipe.

[0029] In summary, during the testing of oily air through this ventilation duct, the inner wall of the duct inevitably becomes contaminated with oil and other impurities. The self-cleaning ventilation duct of this invention stores and provides cleaning fluid through the liquid storage component 3. The cleaning component 2, under the action of airflow and its own structural cooperation, rotates and scrapes, utilizing the cleaning fluid to enhance the cleaning effect. All components work together to effectively clean the inner wall of the ventilation duct, maintaining its good ventilation performance and creating a stable and reliable environment for oily air testing, ensuring the accuracy of test results and the long-term stable operation of the equipment.
