Description

Technical Field

[0001] This invention relates to the field of fume purifier technology, and in particular to an automatic cleaning type fume purifier. Background Technology

[0002] In the daily operation of catering establishments, fume purifiers, as key environmental protection equipment, experience rapid accumulation of viscous grease on their internal battery components after prolonged contact with high-temperature fumes. This leads to a significant decrease in purification efficiency and may cause equipment malfunctions. Under current technology, cleaning the battery components requires interrupting equipment operation, disassembling the entire battery component from the purifier housing, and then transferring it to a dedicated cleaning station for manual cleaning and drying. This process involves multiple handling, installation, and professional operations, causing prolonged equipment downtime, affecting the continuity of catering operations, and significantly increasing maintenance costs due to reliance on external cleaning equipment. Furthermore, repeated disassembly can loosen the battery component structure, reduce sealing performance, and even cause component wear, shortening the overall lifespan of the equipment. Therefore, the complexity, inefficiency, and high cost of the cleaning process have become major obstacles to the efficient and stable operation of fume purifiers, and existing technologies need improvement to address these issues. Summary of the Invention

[0003] The purpose of this application is to provide an automatic cleaning type oil fume purifier, which has the advantages of reducing equipment downtime, reducing maintenance costs, increasing equipment lifespan, and being easy to operate.

[0004] The automatic cleaning type oil fume purifier provided by this invention adopts the following technical solution: An automatic cleaning type oil fume purifier includes: The air purifier housing has a water tank and a detergent storage container fixedly connected to its top. The battery cell is located inside the purifier housing, and multiple sets of electrode plates are installed inside the battery cell. The mixing tank is fixedly connected to the top wall of the purifier box and is connected to the water storage tank and the detergent storage cylinder through a pipe. The mixing tank is equipped with a stirring mechanism. The spray drying mechanism has multiple sets and is adapted to the spacing between the electrode plates. The spray drying mechanism reciprocates vertically between two electrode plates for cleaning and drying. A linkage mechanism is provided between the stirring mechanism and the spray drying mechanism to combine the axial rotation of the stirring mechanism and the linear reciprocating motion of the spray drying mechanism.

[0005] Furthermore, the stirring mechanism includes a rotating rod and stirring blades.

The limit slider is slidably connected to the limit guide rail, and an air duct connector is fixedly connected to the top of the limit slider. The limit slider is a hollow structure.

[0008] Furthermore, a through-pipe groove is provided on the winding reel for the water pipe to pass through the center of both ends of the winding reel.

[0009] Furthermore, the bottom of the hollow scraper is flush with the top of the electrode plate at the beginning of the cleaning process. During cleaning, the middle of the hollow scraper protrudes and abuts against the electrode plates on both sides.

[0010] Furthermore, the linkage mechanism includes a shaft, a transmission gear, a central gear, a toothed gear, a reset sleeve, a transmission rod, a driven gear, a toothed pulley, and a stacked wheel. The shaft is rotatably connected to the outer top wall of the battery cell. The transmission gear is coaxially and fixedly connected to the rotating rod. Both the central gear and the toothed gear are fixedly connected to the shaft. The transmission gear meshes with the central gear to convert vertical circular rotation into planar circular rotation. The reset sleeve is fixedly connected to the top wall of the battery cell to reset the driven gear after it disengages from the toothed gear. The transmission rod is rotatably connected to the reset sleeve. The driven gear is fixedly connected to the transmission rod and meshes with the toothed gear. A toothed pulley is fixedly connected to the top of the transmission rod. A stacked wheel is fixedly connected to the top of the outer wall of the winding wheel. The stacked wheel and the toothed pulley are connected by transmission, and adjacent stacked wheels are also connected by transmission.

[0011] Furthermore, a control box is fixedly connected to the outer wall of the purifier housing, and a material receiving guide groove is provided at the bottom of the purifier housing, with a waste box slidably connected inside the material receiving guide groove.

[0012] Furthermore, a one-way valve is installed between the mixing tank and the water storage tank and the detergent storage container to prevent liquid backflow in the mixing tank.

[0022] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0023] This invention discloses an automatic cleaning type oil fume purifier.

[0025] Reference Figures 1-7 An automatic cleaning type oil fume purifier, comprising: The air purifier housing 1 has a water storage tank 12 and a cleaning agent storage cylinder 13 fixedly connected to its top. The battery cell 2 is located inside the purifier housing 1, and multiple sets of electrode plates 21 are installed inside the battery cell 2. The mixing tank 3 is fixedly connected to the top wall of the purifier housing 1 and is connected to the water storage tank 12 and the detergent storage cylinder 13 through a pipe. The mixing tank 3 is equipped with a stirring mechanism. The spray drying mechanism 5 is provided in multiple sets and is adapted to the spacing between the electrode plates 21. The spray drying mechanism 5 reciprocates vertically between the two electrode plates 21 for cleaning and drying. A linkage mechanism 4 is provided between the stirring mechanism and the spray drying mechanism 5. The linkage mechanism 4 is used to combine the axial rotation of the stirring mechanism and the linear reciprocating motion of the spray drying mechanism 5.

[0026] For ease of understanding, the following explains some key terms in this embodiment: The purifier housing 1 serves as the external structure of the fume purifier, housing the internal purification components and providing overall support and protection. Its top is connected to a water tank 12 for storing cleaning liquids and a cleaning agent storage container 13.

[0027] Battery cell 2 is the core purification unit of the fume purifier, typically composed of multiple sets of electrode plates 21, which capture oil fume particles through electrostatic adsorption and other principles. This battery cell 2 is located inside the purifier housing 1.

[0028] The mixing tank 3 is used to mix the water in the water storage tank 12 and the detergent in the detergent storage container 13 to form a cleaning solution. The mixing tank 3 is fixedly connected to the inner top wall of the purifier body 1 and is connected to the water storage tank 12 and the detergent storage container 13 through pipes.

[0029] The stirring mechanism is installed on the mixing tank 3 to stir the liquid in the mixing tank 3, ensuring that the water and detergent are mixed to the required degree to form a liquid that meets the cleaning standards.

[0030] The spray drying mechanism 5 is used to clean and dry the electrode plates 21 inside the battery cell 2. This mechanism is provided in multiple sets and maintains a preset distance from the electrode plates 21 so that it can reciprocate vertically between the electrode plates 21 to achieve spray cleaning and drying treatment on the surface of the electrode plates 21.

[0031] The linkage mechanism 4 is used to coordinate the axial rotation of the mixing mechanism and the linear reciprocating motion of the spray drying mechanism 5. Through this linkage mechanism 4, the operation of the mixing mechanism and the cleaning and drying process of the spray drying mechanism 5 can be synchronized or carried out in a preset sequence.

[0032] This application provides an automatic cleaning type oil fume purifier, whose structural design is intended to achieve automatic cleaning and drying of the battery cells.

[0033] Specifically, the purifier housing 1 serves as the external frame of the entire device, with its top fixedly connected to a water tank 12 and a detergent storage container 13. The water tank 12 stores clean water, while the detergent storage container 13 stores specialized detergent. Alternatively, the water tank 12 and detergent storage container 13 can be separate containers connected to the mixing tank 3 via pipes. Or, they can be designed as a single unit, internally separated by partitions, but still connected to the mixing tank 3 through their respective outlets.

[0034] The battery cell 2 is located inside the purifier housing 1 and is the core component for oil fume purification. The battery cell 2 contains multiple sets of electrode plates 21, which are the main working surfaces for adsorbing oil fume particles. The battery cell 2 can adopt a modular design for easy installation and maintenance. The electrode plates 21 can be arranged in a parallel plate shape or a honeycomb structure to increase the contact area with oil fumes.

[0035] The mixing tank 3 is fixedly connected to the inner top wall of the purifier housing 1 and is connected to the water storage tank 12 and the detergent storage container 13 via pipes. The main function of the mixing tank 3 is to receive water from the water storage tank 12 and detergent from the detergent storage container 13, and to mix them. The mixing tank 3 is equipped with a stirring mechanism to ensure that the mixing degree of the water and detergent meets the requirements. The stirring mechanism can take various forms; for example, it can be a simple blade agitator driven manually or electrically. Alternatively, mixing can be achieved using water flow impact or bubble agitation; this application uses a motor-driven mechanism.

[0036] Multiple spray drying mechanisms 5 are provided, maintaining a preset distance between them and the electrode plates 21. This mechanism reciprocates vertically between two electrode plates 21 to clean and dry them. The spray drying mechanism 5 sprays cleaning liquid onto the surface of the electrode plates 21. The drying function can be achieved by switching to spraying clean air or hot air after spraying.

[0037] A linkage mechanism 4 is provided between the mixing mechanism and the spray drying mechanism 5. The function of the linkage mechanism 4 is to combine the axial rotation of the mixing mechanism with the linear reciprocating motion of the spray drying mechanism 5.

[0038] The automatic cleaning type oil fume purifier of this application integrates a water storage tank 12, a cleaning agent storage cylinder 13, a mixing tank 3, a stirring mechanism, a spray drying mechanism 5, and a linkage mechanism 4 inside the purifier housing 1, achieving automatic spray cleaning and drying of the inner electrode plates 21 of the battery cell 2. This avoids the need for disassembling the battery cell for external cleaning required in traditional oil fume purifiers, improving cleaning efficiency and reducing manual cleaning costs, thereby enhancing the ease of use and economical maintenance of the oil fume purifier. In response, this application proposes an automatic cleaning type oil fume purifier, which includes a mixing tank 3 for preparing a cleaning solution. However, if the stirring mechanism in the mixing tank 3 lacks a specific and efficient driving and stirring structure, it may lead to uneven mixing of the cleaning agent and water, affecting the concentration and activity of the cleaning solution, thereby reducing the cleaning effect on the electrode plate 21 and failing to fully utilize the performance of the purifier.

[0039] To solve the above problems, refer to Figures 1-7This application further proposes a specific structure for the stirring mechanism. The stirring mechanism includes a rotating rod 31 and stirring blades 32. The rotating rod 31, as the core component of the stirring mechanism, primarily functions to support and drive the stirring blades 32 to rotate. The stirring blades 32 directly act on the liquid within the mixing tank 3, generating shear force, eddies, and convection through their specific shape and distribution as the rotating rod 31 rotates, thereby promoting thorough mixing of the liquid components (such as water and detergent). The stirring blades 32 are typically designed as a multi-blade structure and are evenly distributed along the axial direction of the rotating rod 31 to ensure that the stirring covers the entire effective volume of the mixing tank 3.

[0040] The rotating rod 31 is rotatably connected to the mixing tank 3, with one end extending to the outside of the mixing tank 3. This rotatable connection is typically achieved through a bearing assembly or sealed bushing mounted on the wall of the mixing tank 3, ensuring smooth rotation and effectively preventing liquid leakage from the mixing tank 3. The design of one end of the rotating rod 31 extending to the outside of the mixing tank 3 provides a connection interface for an external power source, allowing the stirring mechanism to obtain driving force from the outside, thereby achieving the stirring operation of the liquid inside the mixing tank 3.

[0041] Multiple stirring blades 32 are evenly distributed on the outer wall of the rotating rod 31. This even distribution of stirring blades 32 on the outer wall of the rotating rod 31 aims to optimize the stirring effect. This uniform distribution ensures that the liquid in the mixing chamber 3 is effectively agitated at different depths and in different areas when the rotating rod 31 rotates, avoiding localized uneven mixing or dead zones. The number and specific shape of the stirring blades 32 can be optimized according to the properties of the mixed liquid (such as viscosity and density) and the geometry of the mixing chamber 3 to achieve the best mixing efficiency.

[0042] A motor 33 is fixedly connected to the outer wall of the battery cell 2. The motor 33 is the actuator that provides rotational power to the stirring mechanism. Fixing it to the outer wall of the battery cell 2 allows full utilization of the battery cell 2 as a structural support, achieving a compact layout and reducing the need for additional mounting brackets. The selection of the motor 33 will take into account its power, speed, and reliability in the working environment of the fume purifier; for example, it may need to have a certain degree of moisture-proof and oil-proof capabilities.

[0043] A pulley assembly 34 is connected between the output shaft of the motor 33 and one end of the rotating rod 31. The pulley assembly 34, as a mechanical transmission device, transmits the rotational motion and torque of the motor 33's output shaft to the rotating rod 31. This pulley assembly 34 typically consists of a driving pulley connected to the output shaft of the motor 33, a driven pulley connected to one end of the rotating rod 31, and a transmission belt. Belt drives offer advantages such as smooth transmission, low noise, overload protection, and easy adjustment of the speed ratio, ensuring the smooth and reliable operation of the stirring mechanism.

[0044] Through the above technical solution, this application provides a specific and efficient stirring mechanism for an automatic cleaning type oil fume purifier. The motor 33 is fixedly connected to the outer wall of the battery cell 2, and its output shaft reliably transmits power to the rotating rod 31 via a pulley assembly 34. The rotating rod 31 rotates within the mixing chamber 3, driving multiple evenly distributed stirring blades 32 on its outer wall to thoroughly stir the water in the water storage tank 12 and the detergent in the detergent storage cylinder 13. This structural design ensures that the detergent and water can be quickly and evenly mixed to form a cleaning liquid of suitable concentration and stable activity. The uniform cleaning liquid can more effectively act on the oil stains on the electrode plate 21, significantly improving the cleaning efficiency of the spray drying mechanism 5, thereby extending the service life of the electrode plate 21 and maintaining the long-term stable purification performance of the oil fume purifier. Example

[0045] In some embodiments described above in this application, a spray drying mechanism 5 is proposed to reciprocate vertically between two electrode plates 21 for cleaning and drying. However, in its implementation, ensuring that the cleaning liquid can be sprayed evenly and efficiently onto the surface of the electrode plates 21, while simultaneously achieving effective scraping and drying to thoroughly remove oil stains, and structurally ensuring stable movement of the cleaning components and liquid supply, is a technical problem that needs to be solved.

[0046] In this regard, refer to Figures 1-7 This application further proposes that the spray drying mechanism 5 includes a connecting cylinder 51, a take-up reel 52, a water pipe 53, and a hollow scraper 55. Multiple connecting cylinders 51 are provided, all of which are fixedly connected to the bottom of the mixing tank 3. The connecting cylinders 51 serve as liquid channels and structural supports between the spray drying mechanism 5 and the mixing tank 3. Their multiple configurations ensure that the cleaning fluid can be distributed to multiple cleaning units to meet the cleaning needs of multiple sets of electrode plates 21. The connecting cylinders 51 are typically made of corrosion-resistant materials to adapt to the cleaning fluid environment. The take-up reel 52 is rotatably connected to the connecting cylinder 51. Its main function is to wind and release the water pipe 53, thereby controlling the lifting and lowering movement of the water pipe 53 and the hollow scraper 55 connected to it. The rotatable connection of the take-up reel 52 ensures the smoothness of the water pipe 53 during winding and unwinding, avoiding jamming. The water pipe 53 is wound around the take-up reel 52, with one end fixedly connected to the mixing tank 3 and the other end passing through the hollow scraper 55. The water pipe 53 serves as the carrier for the cleaning fluid. Its flexible material allows it to wind and release with the take-up reel 52, ensuring that the cleaning fluid can be stably delivered from the mixing tank 3 to the cleaning area. It should be noted that, depending on the number of electrode plates 21, a return spring can be added between some of the take-up reels 52 and the outer wall of the mixing tank 3, thereby improving the ease of reset in conjunction with the linkage mechanism 4.

[0047] Furthermore, a spray head 56 is fixedly connected to the outer wall of the water pipe 53, and multiple movable nozzles 57 are movably connected to the outer side of the spray head 56. The spray head 56 is used to evenly spray the cleaning liquid onto the surface of the electrode plate 21, and various nozzle types can be used to achieve different spraying effects, such as fan-shaped spraying or atomized spraying. The movable nozzles 57 provide more flexible spraying angles and ranges, which can be adjusted according to actual cleaning needs to ensure that the cleaning liquid can cover all corners of the electrode plate 21, thereby improving cleaning efficiency. In addition, a fixed connecting block 54 is also fixedly connected to the outer wall of the water pipe 53, and the fixed connecting block 54 is fixedly connected to the outer wall of the hollow scraper 55. The function of the fixed connecting block 54 is to firmly connect the water pipe 53 and the hollow scraper 55 together, so that the water pipe 53 can both carry water and provide traction. The water pipe 53 can be made of a material with a certain degree of elasticity to facilitate repositioning and ensure that the two remain synchronized during movement to jointly complete the spraying and scraping tasks. The hollow scraper 55 is the core component of the spray drying mechanism 5. Its hollow internal structure is used to convey airflow, while its external structure supports the spray head 56 and movable nozzle 57, and it directly contacts the electrode plate 21 for physical scraping. The hollow scraper 55 is usually made of wear-resistant and corrosion-resistant materials to ensure its stability and effectiveness in long-term use.

[0048] Through the above technical solution, the spray drying mechanism 5 is specifically designed as an integrated system including components such as a connecting cylinder 51, a take-up roller 52, a water pipe 53, and a hollow scraper 55. This design allows the cleaning liquid to be precisely delivered to the spray head 56 and the movable nozzle 57 through the water pipe 53, achieving uniform spraying of the surface of the electrode plate 21, and also spraying the surface of the hollow scraper 55 to clean and scrape the areas. At the same time, the hollow scraper 55 physically scrapes the electrode plate 21 while spraying, effectively removing stubborn oil stains. The cooperation between the take-up roller 52 and the connecting cylinder 51 ensures the stable reciprocating motion of the water pipe 53 and the hollow scraper 55 between the electrode plates 21, thereby realizing the automation and high efficiency of the cleaning and drying process. This structure not only solves the technical problems of uniform spraying and effective scraping of cleaning liquid, but also improves the efficiency and reliability of the entire cleaning system through integrated design, ensuring the thorough cleaning of the electrode plate 21 inside the fume purifier.

[0049] Reference Figures 1-7 The hollow scraper 55 is shaped like two mirror-image trapezoids, exhibiting a structure that is narrow at both ends and wide in the middle. Simultaneously, multiple air outlet slots 551 are evenly distributed on its inclined surface. To ensure the stability of the hollow scraper 55's movement, a limiting slider 553 is fixedly connected to one vertical outer wall of the hollow scraper 55, while a limiting guide rail 58 is fixedly connected to the top of the outer wall of the battery cell 2. The limiting slider 553 and the limiting guide rail 58 are slidably connected. Furthermore, a duct connector 552 is fixedly connected to the top of the limiting slider 553, and the limiting slider 553 is a hollow structure.

[0050] Specifically, the hollow scraper 55 adopts a trapezoidal mirror-shaped configuration that is narrow at both ends and wide in the middle, aiming to optimize its scraping effect and airflow distribution between the electrode plates 21. This special shape allows the scraper 55 to form a certain pressure distribution when in contact with the electrode plates 21, which helps to scrape off the oil stains adhering to the electrode plates 21. At the same time, this shape also provides a structural basis for the guidance and distribution of internal airflow, ensuring that the airflow can act more evenly on the surface of the electrode plates 21 during air drying. Multiple air outlet slots 551 are evenly opened on its inclined surface. These air outlet slots 551 are channels for discharging the air drying airflow. The even opening on the inclined surface ensures that the air drying airflow can be blown onto the surface of the electrode plates 21 at a certain angle and with uniform intensity when the scraper 55 moves, thereby improving the air drying efficiency and avoiding local over-drying or wetting. These air outlet slots 551 are connected to the internal cavity of the hollow scraper 55 and receive the airflow introduced by the air duct connector 552.

[0051] To guide the hollow scraper 55 in sliding and ensure its initial position, a limiting slider 553 is fixedly connected to one vertical outer wall of the hollow scraper 55. This limiting slider 553 ensures the uniformity of the initial position of the hollow scraper 55 and guarantees smooth movement along a preset path during cleaning and drying, preventing shaking or deviation, thus ensuring uniformity of cleaning and drying. The limiting slider 553 is typically made of wear-resistant material to reduce frictional loss. A limiting guide rail 58, used in conjunction with the limiting slider 553, is fixedly connected to the top of the outer wall of the cell 2, providing a precise sliding path for the limiting slider 553 and ensuring the accuracy and stability of the reciprocating motion of the hollow scraper 55 between the electrode plates 21. The limiting guide rail 58 is typically a U-shaped groove or T-shaped groove structure to accommodate and guide the limiting slider 553. The sliding connection between the limiting slider 553 and the limiting guide rail 58 ensures the smooth reciprocating motion of the hollow scraper 55 in the vertical direction, effectively restricts the degree of freedom of the scraper 55 in the horizontal direction, and prevents it from swaying laterally during cleaning and drying, thereby improving the accuracy and efficiency of cleaning and drying.

[0052] In addition, a duct connector 552 is fixedly connected to the top of the limiting slider 553. This duct connector 552 is the interface connecting the external air source and the internal cavity of the hollow scraper 55. The drying airflow is introduced into the hollow scraper 55 through the hollow structure of the limiting slider 553 and then discharged through the air outlet 551. This connection method allows the airflow to be stably and continuously supplied to the scraper 55, achieving efficient drying. The hollow structure of the limiting slider 553 is the key to realizing the transmission of the drying airflow. As a channel between the duct connector 552 and the internal cavity of the hollow scraper 55, it allows the drying airflow to smoothly pass from the external air source through the duct connector 552 and the hollow limiting slider 553, and finally enter the hollow scraper 55. It is then evenly sprayed out through the air outlet 551 to complete the drying operation. It should be noted that the duct here needs to be a flexible hose with a certain winding and unwinding function to facilitate reciprocating motion. This is existing technology and will not be described in detail.

[0053] Through the aforementioned technical solution, the unique trapezoidal mirror shape of the hollow scraper 55 and the evenly distributed air outlet slots 551 enable the drying airflow to act on the surface of the electrode plate 21 at an optimized angle and with uniform intensity, significantly improving drying efficiency and cleaning effect. Simultaneously, the sliding cooperation between the limiting slider 553 and the limiting guide rail 58 provides precise initial positioning and movement guidance for the vertical reciprocating motion of the scraper 55, effectively preventing swaying and deviation of the scraper 55 during cleaning and drying, ensuring the uniformity and thoroughness of cleaning and drying. Furthermore, the hollow structure of the limiting slider 553 and its connection to the duct connector 552 cleverly realize the introduction and transmission of the drying airflow, making the entire drying system compact and functionally complete. This design not only optimizes airflow distribution and improves drying efficiency but also enhances the stability of the scraper 55's movement, thereby ensuring that the fume purifier can efficiently and thoroughly clean and dry the electrode plate 21 during automatic cleaning.

[0054] Reference Figures 1-7The take-up reel 52 has a through-hole 521 for the water pipe 53 to pass through the center of both ends of the take-up reel 52. Specifically, the through-hole 521 is a channel opened on the body of the take-up reel 52 to guide and accommodate the water pipe 53. The through-hole 521 provides a fixed and protected path for the water pipe 53 to pass through the center of rotation of the take-up reel 52. For example, the through-hole 521 can be a circular hole penetrating the axial direction of the take-up reel 52, and its inner wall can be made of a smooth material or fitted with a bushing to reduce friction when the water pipe 53 passes through. The water pipe 53 passing through the center of both ends of the take-up reel 52 means that the water pipe 53 is not simply wound around the outside of the take-up reel 52, but passes through the internal structure of the take-up reel 52 from the center area of ​​its two ends at the axis of rotation. This method of threading ensures that the relative motion between the water pipe 53 and the winding wheel 52 is minimized when the winding wheel 52 rotates, thereby effectively avoiding the twisting, tangling or excessive bending of the water pipe 53 caused by rotation during the winding and unwinding process.

[0055] Through the above technical solution, a through-pipe groove 521 is opened on the winding wheel 52, and the water pipe 53 passes through the center of both ends of the winding wheel 52, effectively solving the problems of entanglement, twisting, and wear that may occur during the winding and unwinding process of the water pipe 53. When the winding wheel 52 rotates to wind up and unwind the water pipe 53, the water pipe 53, because it passes through the central axis of the winding wheel 52, will not rotate or twist significantly with the winding wheel 52, thus maintaining the relative stability of the water pipe 53. This not only significantly reduces the risk of damage to the water pipe 53 due to mechanical stress and extends the service life of the water pipe 53, but also ensures that the cleaning liquid can be continuously and stably delivered to the spray head 56 through the water pipe 53, ensuring the efficiency and reliability of the spray drying mechanism 5 when cleaning the electrode plate 21. This design allows the spray drying mechanism 5 to operate more smoothly and for longer, improving the overall cleaning performance and maintenance convenience of the automatic cleaning type fume purifier.

[0056] Reference Figures 1-7 The bottom of the hollow scraper 55 is flush with the top of the electrode plate 21 at the beginning height, and during cleaning, the middle protruding part of the hollow scraper 55 abuts against the electrode plates 21 on both sides.

[0057] Specifically, the bottom of the hollow scraper 55 is set flush with the top of the electrode plate 21 at its initial height. This ensures that when the hollow scraper 55 begins its downward movement to perform cleaning, it can start covering the topmost area of ​​the electrode plate 21, thus guaranteeing that the entire effective working surface of the electrode plate 21 is cleaned. This avoids blind spots or incomplete cleaning caused by starting too high or too low. This precise initial positioning is the foundation for achieving comprehensive cleaning.

[0058] Simultaneously, during the cleaning process, the central protruding portion of the hollow scraper 55 is designed to form a close contact or slight pressure with the electrode plates 21 on both sides. Given that the hollow scraper 55 has a trapezoidal mirror structure that is narrow at both ends and wide in the middle, the central protruding portion naturally corresponds to its wider area. This contact action allows the hollow scraper 55 to apply a certain physical pressure to the surface of the electrode plates 21 as it reciprocates vertically, effectively scraping and wiping, thereby mechanically removing oil, dust, and particles adhering to the electrode plates 21. This physical contact is particularly crucial for removing stubborn stains and significantly enhances the cleaning effect. Example

[0059] To address this issue, this application proposes an automatic cleaning type oil fume purifier, which includes a stirring mechanism and a spray drying mechanism 5, aiming to achieve automated cleaning inside the oil fume purifier. In some of the above embodiments, the oil fume purifier needs to achieve precise coordination between the continuous axial rotation of the stirring mechanism and the periodic vertical reciprocating motion of the spray drying mechanism 5. However, how to effectively convert the continuous rotational motion of the stirring mechanism into the intermittent or reciprocating linear motion required by the spray drying mechanism 5, and ensure the synchronization and reliability between the two, is a key technical challenge for achieving efficient automatic cleaning. If the linkage mechanism is not properly designed, it may lead to insufficient mixing of the cleaning agent, inaccurate or asynchronous spray drying actions, thereby affecting the overall cleaning effect and the stability of equipment operation.

[0060] Therefore, referring to Figures 1-7This application further specifies the structure of the linkage mechanism 4, which includes a shaft 41, a transmission gear 42, a central gear 43, a toothed gear 44, a reset sleeve 45, a transmission rod 46, a driven gear 47, a toothed pulley 48, and a stacked pulley 49. The shaft 41 is rotatably connected to the outer top wall of the battery cell 2, serving as the core rotating component of the linkage mechanism 4. One end of the shaft is rotatably connected to the outer top wall of the battery cell 2, providing stable rotational support for the entire transmission chain. Its main function is to bear and transmit the rotational power from the stirring mechanism and distribute it to the subsequent gear set, thereby achieving the conversion of motion mode. The shaft 41 is typically made of high-strength, wear-resistant metal material to ensure stability and reliability during long-term operation. The transmission gear 42 is coaxially fixedly connected to the rotating rod 31, directly receiving the rotational power from the rotating rod 31. As the input end of the linkage mechanism 4, it introduces the continuous axial rotation of the stirring mechanism into the transmission system. The tooth profile and module of the transmission gear 42 must match those of the central gear 43 to ensure smooth and efficient meshing transmission. Both the intermediate gear 43 and the toothless gear 44 are fixedly connected to the shaft 41. The transmission gear 42 meshes with the intermediate gear 43 to convert vertical circular rotation into planar circular rotation. The function of the intermediate gear 43 is to convert the vertical circular rotation of the transmission gear 42 into the planar circular rotation of the shaft 41, thereby changing the transmission direction and plane. The design of the intermediate gear 43 helps optimize the spatial layout and provides a basis for subsequent intermittent motion conversion. The toothless gear 44 is a key component for realizing intermittent motion. It has a structure with partially missing teeth. When it rotates, it periodically meshes with and disengages from the driven gear 47. This design allows the driven gear 47 to rotate when it receives power and stop rotating when the missing tooth section passes, thereby converting continuous rotational motion into intermittent rotational motion. The missing tooth angle and the number of teeth of the toothless gear 44 determine the period and duration of the intermittent motion. The reset sleeve 45 is fixedly connected to the top wall of the cell 2 and is used to reset the driven gear 47 after it disengages from the toothless gear 44. The main function of the reset sleeve 45 is to provide a stable reset support and guide for the driven gear 47 after it disengages from the toothed gear 44. This helps ensure that the driven gear 47 can be accurately aligned during the next engagement, avoiding jamming or misalignment, thereby ensuring the smoothness and reliability of the mechanism's operation. The reset sleeve 45 is usually made of wear-resistant material to reduce friction and wear. The transmission rod 46 is rotatably connected to the reset sleeve 45 and carries the driven gear 47 and the toothed pulley 48. It rotates under the support of the reset sleeve 45 and transmits the intermittent rotational motion obtained from the toothed gear 44 to the toothed pulley 48. The length and rigidity of the transmission rod 46 must meet the transmission requirements to avoid deformation or vibration during transmission. The driven gear 47 is fixedly connected to the transmission rod 46 and meshes with the toothed gear 44. It receives the intermittent rotational power transmitted by the toothed gear 44 and transmits this power to the transmission rod 46.The tooth profile and number of teeth of the driven gear 47 must be precisely matched with the toothless gear 44 to ensure a smooth transition and accurate transmission during engagement and disengagement. A toothed pulley 48 is fixedly connected to the top of the transmission rod 46, which transmits the intermittent rotational motion of the transmission rod 46 to the stacked pulley 49 via a toothed belt. The toothed pulley 48 is typically used in conjunction with the toothed belt to achieve synchronous, slip-free power transmission, ensuring precise control of the spray drying mechanism 5. A stacked pulley 49 is fixedly connected to the top of the outer wall of the take-up pulley 52. ​​The stacked pulley 49 is connected to the toothed pulley 48, and adjacent stacked pulleys 49 are also connected. The stacked pulley 49 receives the intermittent rotational power from the toothed pulley 48 and transmits it to the take-up pulley 52, thereby driving the take-up pulley 52 to intermittently wind up or unwind, thus controlling the vertical reciprocating motion of the spray drying mechanism 5. Furthermore, adjacent stacked pulleys 49 are also connected, meaning that multiple spray drying mechanisms 5 can achieve synchronous or coordinated action through this linkage mechanism 4. The design of the stacked wheel 49 ensures that multiple spray drying mechanisms 5 can work together to improve cleaning efficiency.

[0061] Through the above technical solution, this application ingeniously converts the continuous axial rotation of the stirring mechanism into the intermittent vertical reciprocating motion required by the spray drying mechanism 5. Specifically, the rotating rod 31 of the stirring mechanism transmits continuous rotational power to the shaft 41 through the transmission gear 42 and the intermediate rotating gear 43. The toothed gear 44 fixedly connected to the shaft 41 periodically meshes and disengages with the driven gear 47, thereby converting the continuous rotational motion into the intermittent rotation of the driven gear 47. When the driven gear 47 disengages from the toothed gear 44, the reset sleeve 45 provides support for the transmission rod 46, ensuring its stable reset. Subsequently, the toothed pulley 48 at the top of the transmission rod 46 transmits the intermittent rotational power to the stacked wheel 49 on the take-up wheel 52 through the toothed belt, thereby driving the spray drying mechanism 5 to perform precise intermittent lifting and lowering motion. At the same time, the transmission connection between adjacent stacked wheels 49 ensures that multiple spray drying mechanisms 5 can perform cleaning and drying operations synchronously or in coordination. Through the above technical solution, efficient, precise and reliable motion conversion and synchronous control between the stirring mechanism and the spray drying mechanism 5 are achieved, effectively solving the problem of coordinating continuous rotation and intermittent reciprocating motion, ensuring the full mixing of the cleaning agent and the thorough cleaning and drying of the electrode plate 21, significantly improving the automated cleaning effect and operational stability of the fume purifier. It should be noted that a flat spiral spring or other springs or components with reset function can be placed inside the reset sleeve 45. Example

[0062] Reference Figures 1-7 A control box 11 is fixedly connected to the outer wall of the purifier housing 1, and a material receiving guide 14 is provided at the bottom of the purifier housing 1. A waste box 15 is slidably connected inside the material receiving guide 14.

[0063] The control box 11 serves as the operation and management center of the fume purifier. Its main function is to provide a human-machine interface, enabling control of various functions, status display, and fault alarms. Specifically, the control box 11 can integrate components such as a touch screen, buttons, and indicator lights for starting / stopping the cleaning program, selecting the cleaning mode, setting the cleaning cycle, displaying the current operating status, and providing maintenance information. The control box 11 typically contains electronic components such as a microcontroller, memory, and communication module, used to receive user commands, execute control logic, collect sensor data, and drive actuators. Through the control box 11, users can easily operate and monitor the fume purifier, improving the equipment's intelligence and user experience.

[0064] The receiving trough 14 is a structure used to guide and collect waste liquid and oil generated during the cleaning process. It is typically designed as a trough with a certain slope or curvature, located at the bottom of the purifier housing 1, ensuring that the waste liquid can flow smoothly to the pre-designated collection area. The material of the receiving trough 14 should be corrosion-resistant and easy to clean to withstand the erosion of oil and cleaning agents. Its structural design should take into account the flow rate and viscosity of the waste liquid to avoid clogging or overflow. Through the receiving trough 14, the waste liquid after cleaning can be concentrated and guided, facilitating subsequent waste liquid collection and treatment.

[0065] Waste container 15 is a container for temporarily storing waste liquid and oil collected from receiving chute 14. Waste container 15 is typically designed as a removable, easy-to-clean structure, allowing users to periodically remove and empty it for cleaning. It is slidably connected to receiving chute 14, enabling easy insertion and removal. The capacity of waste container 15 should be rationally designed based on the cleaning frequency of the fume purifier and the amount of waste liquid generated to reduce the frequency of emptying by the user. Furthermore, waste container 15 can be equipped with a level sensor; when the waste reaches a certain height, an alarm will sound via control box 11 to remind the user to handle it promptly.

[0066] Through the above technical solution, a control box 11 is fixedly connected to the outer wall of the purifier housing 1, allowing users to operate and monitor the fume purifier intuitively and conveniently, achieving automated management of the cleaning process and greatly improving the ease of use and intelligence of the equipment. Simultaneously, a material receiving guide trough 14 is provided at the bottom of the purifier housing 1, with a waste box 15 slidably connected inside. This effectively collects wastewater, oil, and other waste generated during the cleaning process, preventing indiscriminate leakage or environmental pollution. The material receiving guide trough 14 ensures smooth flow of wastewater, while the slidably connected waste box 15 facilitates the dumping and cleaning of waste, simplifying the equipment maintenance process. This design not only ensures the integrity of the fume purifier's cleaning function but also optimizes the user experience, ensuring the cleanliness and environmental friendliness of the equipment. Example

[0067] Reference Figures 1-7 A one-way valve is installed between the mixing tank 3 and the water storage tank 12 and the detergent storage container 13 to prevent backflow of liquid in the mixing tank 3. Specifically, a one-way valve is a valve that allows fluid to flow in only one direction. When fluid enters from the positive inlet, the valve opens; when fluid attempts to enter from the reverse inlet, the valve closes, thus preventing backflow. This one-way valve can take various forms, such as a spring-loaded check valve, a lift check valve, or a swing check valve, and its core function is to ensure unidirectional fluid flow. The one-way valves are installed on the pipes between the mixing tank 3 and the water storage tank 12, and on the pipes between the mixing tank 3 and the detergent storage container 13. This means that water and detergent can flow into the mixing tank 3 from the water storage tank 12 and the detergent storage container 13 for mixing, but the mixed liquid or any unmixed liquid cannot flow back from the mixing tank 3 to the water storage tank 12 or the detergent storage container 13.

[0068] By implementing the above technical solution, a one-way valve is installed between the mixing tank 3 and the water storage tank 12 and the detergent storage cylinder 13. This effectively prevents the mixed liquid or detergent in the mixing tank 3 from flowing back into the water storage tank 12 and the detergent storage cylinder 13. This ensures the purity of the water in the water storage tank 12 and avoids dilution or contamination of the concentrated detergent in the detergent storage cylinder 13, thereby guaranteeing the accuracy of the detergent ratio and improving the quality of the cleaning solution preparation. Simultaneously, the one-way valve also prevents pipe blockage or equipment damage that may result from liquid backflow, enhancing the stability and reliability of the fume purifier's operation, extending the equipment's service life, and ensuring that the fume purifier uses accurately proportioned and stable cleaning solutions in each cleaning cycle, thus improving overall cleaning efficiency and effectiveness.

[0069] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
