Description

Technical Field

[0001] This invention relates to the field of valve technology, and in particular to a regulating butterfly valve with an electric actuator. Background Technology

[0002] In industrial pipeline transportation systems, regulating butterfly valves, as a commonly used flow control device, are widely used in various fields such as petroleum, chemical, water conservancy, and metallurgy, primarily for controlling the flow and velocity regulation of media within pipelines. With the increasing demands for stability, sealing, and ease of maintenance in industrial production, regulating butterfly valves with electric actuators, due to their automated regulation capabilities, have gradually become the mainstream application product. Currently, most regulating butterfly valves with electric actuators on the market possess basic flow velocity regulation and media transportation functions, but they still have many shortcomings in media filtration, impurity removal, and equipment maintenance, making it difficult to meet the high-efficiency and stable operation requirements of industrial production.

[0003] Existing regulating butterfly valves with electric actuators mainly consist of pipelines, electric actuators, regulating mechanisms, and valve bodies. The electric actuator serves as a power source, outputting torque upon startup and transmitting it to the regulating mechanism. The rotation of internal components within the regulating mechanism alters the flow cross-sectional area of ​​the medium within the pipeline, thereby achieving flow rate regulation. Some butterfly valves incorporate a simple filter structure within the valve body to intercept impurities in the medium, preventing them from entering the regulating mechanism and affecting its operation. For impurities on the inner wall of the pipeline and the surface of the filter structure, it is usually necessary to disassemble the entire valve body for cleaning. Even some washable filter structures require multiple fasteners for fixation, making the disassembly and assembly process cumbersome.

[0004] In existing technologies, impurities easily adhere to the surface of the filter structure and the inner wall of the pipe, and there is a lack of convenient cleaning mechanisms. Cleaning requires the disassembly of multiple parts, which is cumbersome and not only affects cleaning efficiency but also easily leads to impurity accumulation and blockage of the pipe, causing filter structure failure, which in turn affects media flow efficiency and shortens equipment lifespan. Furthermore, the sealing and precision of flow rate adjustment are insufficient. The adjustment mechanism is prone to shaking during rotation, and the unreasonable design of the sealing structure is prone to media leakage, which affects adjustment accuracy and poses safety hazards, failing to meet the precise adjustment requirements under different operating conditions. Finally, the disassembly and maintenance efficiency is low. The disassembly and assembly of the cleaning mechanism and filter structure require special tools and are cumbersome, consuming a lot of manpower and time, significantly increasing the workload and time cost of equipment maintenance, and reducing the ease of use of the equipment. Summary of the Invention

[0005] To overcome the above shortcomings, the present invention provides a regulating butterfly valve with an electric actuator, which aims to improve the problems of inconvenient impurity cleaning, insufficient sealing and accuracy of flow rate regulation, low disassembly and maintenance efficiency, and difficulty in ensuring long-term equipment stability in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A regulating butterfly valve with an electric actuator includes a pipe body, an electric actuator fixedly mounted at the top end of the pipe body, an adjusting mechanism connected to the output end of the electric actuator, a valve body fixedly mounted on the outside of the pipe body, a filter disassembly and assembly mechanism provided at the top end of the valve body, and a cleaning mechanism provided inside the valve body. The filter assembly / disassembly mechanism includes a housing, the bottom of which is fixedly mounted on the top of the valve body. A wedge-shaped locking block is slidably connected inside the housing. A telescopic column is fixedly mounted on one end of the wedge-shaped locking block near the electric actuator. A spring is sleeved on the outside of the telescopic column. A control handle is slidably mounted inside the housing. A filter assembly is installed inside the valve body. As a further description of the above technical solution: The filter assembly includes a mounting plate, which is externally slidably mounted inside the valve body. Guide blocks are integrally formed on both sides of the mounting plate, and a filter disc is fixedly mounted inside the mounting plate. As a further description of the above technical solution: The valve body has an internal groove for the guide block to slide in, and the control handle is externally fixed to the end of the wedge-shaped block near the electric actuator. As a further description of the above technical solution: One end of the spring is fixedly mounted on the wedge-shaped block, and the other end of the spring is fixedly mounted inside the outer casing; As a further description of the above technical solution: The cleaning mechanism includes a rotating ring, which is rotatably mounted inside the mounting plate. A drive gear is rotatably mounted inside the mounting plate and meshes with the rotating ring. A rotating handle is rotatably mounted inside the mounting plate. A filter scraper is fixedly mounted on the inner wall of the rotating ring. A fixing post is integrally formed on the outside of the filter scraper. A pipe scraper is slidably mounted inside the fixing post. A fixing screw is threadedly connected inside the fixing post. As a further description of the above technical solution: The outer side of the filter scraper is in contact with the outer side of the filter disc, the outer side of the pipe scraper is in contact with the inner side wall of the pipe body, the outer side of the fixing screw is slidably mounted inside the pipe scraper, and the outer side of the rotating handle is fixedly mounted outside the drive gear. As a further description of the above technical solution: The adjustment mechanism includes an upper fastener, the top end of which is connected to the output end of the electric actuator. A sealing disc is fixedly mounted on the outside of the upper fastener, and a sealing cover is fixedly mounted on the outside of the sealing disc. A lower fixed shaft is fixedly mounted on the inner wall of the tube, and a lower rotating component is rotatably mounted on the outer circumference of the lower fixed shaft. As a further description of the above technical solution: The lower rotating component is externally fixed to the outside of the sealing disc, and the telescopic column is externally slidably mounted inside the outer casing.

[0007] The present invention has the following beneficial effects: 1. In this invention, when the medium flows through the pipe, it passes through the filter component to intercept impurities, preventing impurities from accumulating and affecting flow efficiency or damaging the equipment. When impurities adhere to the surface of the filter component and the inner wall of the pipe, the transmission structure is driven by the manual operation control component to drive the scraper to contact and scrape the surface of the filter component and the inner wall of the pipe, which can quickly remove the attached impurities, prevent pipe blockage and filter component failure. At the same time, the scraper can be easily disassembled and installed, which is convenient for subsequent cleaning and maintenance, effectively ensuring the long-term stable operation of the valve body and extending the service life of the equipment.

[0008] 2. In this invention, during the medium flow rate adjustment process, the electric actuator outputs a stable torque after starting, transmitting power to the adjustment mechanism to drive the relevant components to rotate smoothly within the pipe. At the same time, the limiting structure constrains the rotating components to ensure the stability of the rotation process. Combined with the triple eccentric structure, a reliable dynamic seal is formed, effectively preventing medium leakage along the gap between the actuator shaft and the valve body. This not only ensures the sealing performance during the adjustment process but also achieves precise control of the medium flow rate, meeting the flow rate adjustment requirements under different working conditions.

[0009] 3. In this invention, the cleaning mechanism can be quickly disassembled and assembled through the filter disassembly and assembly mechanism. During disassembly, the pipe scraper is first removed, and then the clamping structure is moved by the operation control component to release the fixation of the filter component. The filter component can then be pulled out of the valve body as a whole, which facilitates a comprehensive cleaning or replacement of the filter component and scraper. During installation, the filter component is simply pushed precisely into the valve body. With the reset effect of the elastic structure, the clamping structure can automatically fix the filter component. Then, the pipe scraper is assembled to complete the installation. The entire disassembly and assembly process is convenient and efficient, which greatly reduces the workload and time cost of equipment maintenance and improves the ease of use of the equipment.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Example: A regulating butterfly valve with an electric actuator, see reference Figure 1 , Figure 3 , Figure 4 and Figure 5The system includes a pipe body 1, with an electric actuator 2 fixedly mounted at its top. The pipe body 1 serves as the core channel for media flow, providing the mounting base for all components of the regulating butterfly valve. The electric actuator 2, fixed at the top of the pipe body 1, outputs a stable torque to power the rotation of the regulating mechanism 4, and is the core power component for achieving the automatic regulating function of the butterfly valve. The output end of the electric actuator 2 is connected to the regulating mechanism 4. The regulating mechanism 4, connected to the output end of the electric actuator 2, receives the torque transmitted by the electric actuator 2 and rotates, thereby controlling the flow cross-sectional area of ​​the media within the pipe body 1, achieving precise regulation of the media flow rate, and ensuring flow control accuracy. A valve body 3 is fixedly mounted on the outside of the pipe body 1. The valve body 3, fixed to the outside of the pipe body 1, not only reinforces and protects the pipe body 1, but also provides a stable mounting carrier for the filter disassembly mechanism 5 and the cleaning mechanism 6. Simultaneously, it works with the regulating mechanism 4 to achieve a seal, preventing media leakage. A filter disassembly and assembly mechanism 5 is installed at the top of the valve body 3. This mechanism allows for the filtration of the medium flowing within the pipe body 1 and provides quick disassembly and assembly, facilitating subsequent cleaning, maintenance, and replacement of the filter components and cleaning mechanism 6, thus improving the ease of use of the butterfly valve. The cleaning mechanism 6 is also located inside the valve body 3. This mechanism scrapes and cleans impurities from the surface of the filter components and the inner wall of the pipe body 1, preventing impurities from accumulating and clogging the pipes, thus ensuring the long-term stable operation of the butterfly valve.

[0014] The filter assembly / disassembly mechanism 5 includes a housing 51, the bottom of which is fixedly mounted on the top of the valve body 3. The housing 51 serves as the external load-bearing component of the filter assembly / disassembly mechanism 5, providing installation and sliding space for internal components such as the wedge-shaped locking block 52 and the telescopic column 53. It also protects internal components and prevents media contamination. The wedge-shaped locking block 52 is slidably connected inside the housing 51. Its wedge-shaped structure allows for automatic avoidance during filter assembly 56 installation. After installation, it can be snapped into the filter assembly 56, achieving rapid fixation and ensuring the stability of the filter assembly 56 after installation. A telescopic column 53 is fixedly installed at one end of the wedge-shaped block 52 near the electric actuator 2. The telescopic column 53 is fixed at one end of the wedge-shaped block 52 near the electric actuator 2 and can extend and retract synchronously with the wedge-shaped block 52. It plays a limiting and guiding role in the sliding of the wedge-shaped block 52, preventing the wedge-shaped block 52 from deviating when sliding. At the same time, it works with the spring 54 to realize the automatic reset of the wedge-shaped block 52.

[0015] A spring 54 is sleeved on the outside of the telescopic column 53. The spring 54 is sleeved on the outside of the telescopic column 53 and is in a compressed state when the wedge-shaped block 52 avoids the filter assembly 56. After the filter assembly 56 slides to the designated position, the spring 54 can release elastic potential energy and automatically push the wedge-shaped block 52 to slide in the opposite direction and lock into the filter assembly 56, so as to achieve quick fixation of the filter assembly 56 without manual locking.

[0016] The housing 51 is equipped with a control handle 55, which is slidably installed inside the housing 51. The control handle 55 can be manually pulled to drive the wedge-shaped block 52 to slide, thereby separating the wedge-shaped block 52 from the filter assembly 56, which facilitates the disassembly of the filter assembly 56. The operation is convenient and labor-saving, improving the efficiency of disassembly and assembly.

[0017] The valve body 3 is equipped with a filter assembly 56. The filter assembly 56 is the core component for media filtration. It can intercept impurities in the media, prevent impurities from entering the pipeline or damaging other components, and at the same time provide an installation base for the cleaning mechanism 6, so that the cleaning mechanism 6 can scrape off the impurities.

[0018] The filter assembly 56 includes a mounting plate 561, which is externally slidably mounted inside the valve body 3. The mounting plate 561 is slidably mounted inside the valve body 3, which can realize the overall disassembly and assembly of the filter assembly 56, providing a stable mounting carrier for the filter disc 563 and the cleaning mechanism 6. At the same time, its sliding design facilitates the subsequent cleaning and replacement of the filter assembly 56.

[0019] The mounting plate 561 has guide blocks 562 integrally formed on both sides. The guide blocks 562 are integrally formed with the mounting plate 561, and the structure is stable. They can be slidably embedded in the groove inside the valve body 3, and play a precise guiding role in the sliding of the mounting plate 561, ensuring that the mounting plate 561 can be smoothly and accurately installed into or removed from the valve body 3, and avoiding installation misalignment.

[0020] A filter disc 563 is fixedly installed inside the mounting plate 561. The filter disc 563 is fixed inside the mounting plate 561 and can filter the medium flowing in the pipe body 1, intercept impurities in the medium, prevent impurities from accumulating and clogging the pipe or affecting the normal operation of the regulating mechanism 4, and ensure the smooth flow of the medium.

[0021] The valve body 3 has a sliding groove inside for the guide block 562 to slide. The sliding groove inside the valve body 3 is adapted to the guide block 562, providing a stable sliding space for the guide block 562, ensuring that the mounting plate 561 will not shift during disassembly and assembly, while improving the smoothness of the sliding of the mounting plate 561, and further improving the disassembly and assembly efficiency of the filter assembly 56.

[0022] The control handle 55 is externally fixed to one end of the wedge-shaped block 52 near the electric actuator 2. The control handle 55 is fixedly connected to the wedge-shaped block 52, which can realize the synchronous transmission of power. When the control handle 55 is pulled, it can accurately drive the wedge-shaped block 52 to slide, ensuring that the wedge-shaped block 52 can be smoothly separated from the filter assembly 56, and ensuring the smoothness of the disassembly operation of the filter assembly 56.

[0023] One end of the spring 54 is fixedly mounted on the wedge-shaped block 52, and the other end of the spring 54 is fixedly mounted inside the housing 51. The two ends of the spring 54 are fixed to the wedge-shaped block 52 and the housing 51 respectively, which can ensure that the spring 54 is always in a stable extension and contraction state when the wedge-shaped block 52 slides. This can achieve automatic avoidance of the wedge-shaped block 52 and automatically push the wedge-shaped block 52 to reset after installation, ensuring the rapid fixation of the filter assembly 56.

[0024] The telescopic column 53 is externally slidably mounted inside the housing 51. The telescopic column 53 is slidably mounted inside the housing 51, which can precisely limit the sliding trajectory of the wedge-shaped block 52, prevent the wedge-shaped block 52 from tilting or deviating when sliding, and ensure that the wedge-shaped block 52 can accurately engage or disengage from the filter assembly 56, thus ensuring the stable operation of the filter assembly / disassembly mechanism 5.

[0025] Reference Figures 4 to 6 The cleaning mechanism 6 includes a rotating ring 65, which is rotatably mounted inside the mounting plate 561. Driven by the drive gear 66, the rotating ring 65 rotates, thereby driving the filter scraper 62 and the pipe scraper 63 to rotate synchronously, providing power for the scraping and cleaning function of the cleaning mechanism 6. It is the core rotating component of the cleaning mechanism 6. The drive gear 66 is rotatably mounted inside the mounting plate 561, meshing with the rotating ring 65. The drive gear 66 converts the power transmitted by the handle 67 into the rotational power of the rotating ring 65, achieving precise power transmission and ensuring that the rotating ring 65 rotates smoothly and synchronously.

[0026] The mounting plate 561 is internally equipped with a rotating handle 67, which is a manual operating component of the cleaning mechanism 6. Rotating the handle 67 drives the drive gear 66, thereby powering the entire cleaning mechanism 6. This convenient operation allows staff to easily clean the pipes and filter discs. A filter scraper 62 is fixedly mounted on the inner wall of the rotating ring 65. The scraper 62 rotates synchronously with the ring, and its outer surface contacts the surface of the filter disc 563. During rotation, it scrapes away impurities adhering to the surface of the filter disc 563, preventing impurities from accumulating and clogging the disc, thus ensuring normal media flow.

[0027] The filter scraper 62 has an integrally formed fixing post 61 on its exterior. The fixing post 61 is integrally formed with the filter scraper 62, which has a stable structure and can provide a foundation for the installation and fixing of the pipe scraper 63. At the same time, it is convenient to disassemble and assemble the pipe scraper 63, making it convenient for workers to clean or replace the pipe scraper 63.

[0028] The fixed column 61 is equipped with a pipe scraper 63 that slides inside. The pipe scraper 63 is slidably installed inside the fixed column 61 and can rotate synchronously with the rotating ring 65 and the filter scraper 62. Its outer side contacts the inner wall of the pipe body 1. When rotating, it can scrape off the impurities attached to the inner wall of the pipe body 1, avoid excessive accumulation of impurities to block the pipe, and ensure smooth flow of the medium in the pipe body 1.

[0029] The internal thread of the fixed column 61 is connected to a fixing screw 64. The fixing screw 64 is threaded to the fixed column 61, which can firmly fix the pipe scraper 63 to the fixed column 61, preventing the pipe scraper 63 from falling off during the rotation cleaning process. At the same time, unscrewing the fixing screw 64 can realize the quick disassembly of the pipe scraper 63, which is convenient for assembly and maintenance.

[0030] The outer side of the filter screen scraper 62 is in contact with the outer side of the filter disc 563. The filter screen scraper 62 is in close contact with the surface of the filter disc 563. When rotating, it can completely scrape off the impurities on the surface of the filter disc 563, ensuring that the filter holes of the filter disc 563 are not blocked, maintaining the filtration effect of the filter disc 563, and ensuring the smooth flow of the medium.

[0031] The outer side of the pipe scraper 63 is in contact with the inner wall of the pipe body 1. The pipe scraper 63 is in close contact with the inner wall of the pipe body 1. When rotating, it can completely scrape off the deposits on the inner wall of the pipe body 1, avoiding excessive accumulation of impurities that affect the flow rate of the medium. At the same time, it prevents impurities from corroding the inner wall of the pipe body 1 and extends the service life of the pipe body 1.

[0032] The fixing screw 64 is externally slidably installed inside the pipe scraper 63. The fixing screw 64 is slidably installed inside the pipe scraper 63 and can be engaged with the fixing post 61 through threads to realize the detachable connection between the pipe scraper 63 and the fixing post 61. This ensures the stability of the pipe scraper 63 after installation and facilitates the disassembly and maintenance of the pipe scraper 63.

[0033] The rotating handle 67 is externally fixed to the outside of the drive gear 66. The rotating handle 67 is fixedly connected to the drive gear 66. When the rotating handle 67 is rotated, it can directly drive the drive gear 66 to rotate synchronously, thereby driving the rotating ring 65, the filter scraper 62 and the pipe scraper 63 to run, realizing the direct transmission of power and ensuring the stability and synchronicity of the cleaning mechanism 6.

[0034] Reference Figure 1 and Figure 2The regulating mechanism 4 includes an upper fastener 43, the top of which is connected to the output end of the electric actuator 2. This connection securely receives the torque transmitted by the electric actuator 2 and transfers it to the sealing disc 42 and the sealing cover 41, ensuring stable torque transmission, preventing slippage, and guaranteeing the normal operation of the regulating mechanism 4. A sealing disc 42 is fixedly mounted externally on the upper fastener 43. The sealing disc 42 rotates synchronously with the upper fastener 43. It cooperates with the sealing cover 41 to form a reliable dynamic seal under the triple eccentric structure, preventing leakage of the medium along the gap between the electric actuator 2 shaft and the valve body 3, thus ensuring the sealing performance during the regulating process.

[0035] A sealing cover 41 is fixedly installed on the outside of the sealing disc 42. The sealing cover 41 is fixed to the outside of the sealing disc 42 and can rotate synchronously with the sealing disc 42. By rotating, the flow cross-sectional area of ​​the medium in the pipe body 1 is changed, so as to achieve precise adjustment of the medium flow rate. At the same time, it works with the sealing disc 42 to enhance the sealing effect and further prevent medium leakage.

[0036] The inner wall of the pipe body 1 is fixedly equipped with a lower fixed shaft 45. The lower fixed shaft 45 is fixed to the inner wall of the pipe body 1, which can provide a stable rotation support point for the lower rotating component 44, limit the rotation trajectory of the lower rotating component 44, ensure the stability of the sealing disc 42 and the sealing cover 41 when rotating, and improve the accuracy of flow regulation.

[0037] The lower fixed shaft 45 is rotatably mounted on the outer periphery of the lower fixed shaft 45. The lower rotating component 44 is rotatably mounted on the outer periphery of the lower fixed shaft 45 and can rotate synchronously with the sealing disc 42. Its cooperation with the lower fixed shaft 45 can provide a limiting support for the sealing disc 42, prevent the sealing disc 42 from shifting when rotating, and ensure the accuracy of the flow rate adjustment of the sealing cover 41.

[0038] The lower rotating component 44 is externally fixed to the outside of the sealing disc 42. The lower rotating component 44 is fixedly connected to the sealing disc 42, which can transmit the limiting support of the lower fixed shaft 45 to the sealing disc 42, ensuring that the sealing disc 42 and the sealing cover 41 remain stable during rotation, avoiding tilting or offset, and ensuring the sealing performance and flow control accuracy of the adjusting mechanism 4.

[0039] The implementation principle of this application embodiment is as follows: A regulating butterfly valve with an electric actuator consists of a pipe body 1 and an electric actuator 2 installed above the pipe body 1. The drive shaft of the electric actuator 2 passes through the lower pipe body 1. An regulating mechanism 4 is provided inside the pipe body 1 to control the flow rate inside the pipe body 1. A valve body 3 is fixedly connected to one end of the pipe body 1. A filter disassembly and assembly mechanism 5 for filtering and disassembling the filter components is provided inside the valve body 3. A cleaning mechanism 6 for cleaning the inner wall of the pipe and cleaning the filter screen is also provided inside the filter disassembly and assembly mechanism 5.

[0040] First, when it is necessary to adjust the flow rate of the medium inside the pipe body 1, the electric actuator 2 is activated. The electric actuator 2 outputs torque and transmits the torque to the adjustment mechanism 4, driving the upper fastener 43 to rotate, so that the sealing cover 41 and the sealing disc 42 rotate inside the pipe body 1. When the sealing disc 42 rotates, the lower rotating part 44 on the outside will be restricted to rotate by the lower fixed shaft 45, ensuring the stability of the rotation of the sealing cover 41 and the sealing disc 42. The cooperation between the sealing cover 41 and the sealing disc 42 forms a reliable dynamic seal under the action of the triple eccentric structure, effectively preventing the medium from leaking along the gap between the actuator shaft 2 and the valve body 3, and ensuring the sealing performance and flow control accuracy during the adjustment process.

[0041] Secondly, when the medium flows inside the pipe body 1, it will be filtered by the filter disc 563. When it is necessary to clean the inside of the pipe body 1 and the surface of the filter disc 563 to prevent impurities from adhering and affecting the flow of the medium, the rotating handle 67 on the outside of the mounting plate 561 is rotated, causing the drive gear 66 to rotate inside the mounting plate 561. The rotating ring 65, which meshes with the drive gear 66, will rotate inside the mounting plate 561. The rotation of the rotating ring 65 causes the filter scraper 62 and the pipe scraper 63 to scrape inside the pipe body 1. The pipe scraper 63 contacts the inner wall of the pipe body 1 to scrape off the deposits on the inner wall of the pipe body 1 to prevent excessive accumulation. The filter scraper 62 contacts the surface of the filter disc 563 to scrape the surface of the filter disc 563 to prevent excessive accumulation of impurities and affect the normal flow of the medium, effectively ensuring the normal use of the valve body. The pipe scraper 63 can be disassembled and reassembled with the fixed shaft 61 by the fixing screw 64, which is convenient for assembly and disassembly.

[0042] The cleaning mechanism 6 can be quickly disassembled and assembled via the filter disassembly and assembly mechanism 5, facilitating cleaning and maintenance. First, the pipe scraper 63 needs to be removed from the inner cavity of the pipe body 1 using the fixing screws 64. Then, by pulling the control handle 55 inside the outer shell 51, the control handle 55 causes the wedge-shaped locking block 52 to slide inside the filter assembly 56 and the outer shell 51. Once the wedge-shaped locking block 52 has slid out of the filter assembly 56, the entire filter assembly 56 can be pulled out from inside the valve body 3. At this point, the filter disc 563 and the filter scraper 62 can be cleaned and replaced. For installation, simply remove the mounting plate 5... 61 is inserted into the valve body 3 to ensure that the guide block 562 slides in the groove inside the valve body 3. During the sliding process, the inclined surface design of the top of the wedge-shaped block 52 makes the wedge-shaped block 52 automatically avoid the filter assembly 56. At the same time, the spring 54 and the telescopic column 53 will retract. The spring 54, which is in a compressed state, will automatically push the wedge-shaped block 52 to slide in the opposite direction after the filter assembly 56 slides to the designated position, so that the wedge-shaped block 52 is locked into the filter assembly 56 again to achieve assembly. At this time, the pipe scraper 63 can be assembled in the inner cavity of the pipe body 1 to complete the rapid assembly of the cleaning mechanism 6.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
