Benefits of technology

[0025]The aforementioned vacuuming device includes a receiving component, a magnetic suction mechanism, a controller, and an adsorption mechanism. When it is necessary to adsorb ferromagnetic metal debris, the controller controls the magnetic suction component to be energized and increases the current of the magnetic suction component, so that the magnetic suction component can adsorb the ferromagnetic metal debris onto the magnetic suction component. Then, the controller controls the current of the magnetic suction component to be reduced, thereby making the adsorption capacity of the magnetic suction component weaker. The controller controls the adsorption mechanism to open. Since the edge of the receiving opening located on the side of the first wall opposite to the receiving cavity is surrounded by a guide portion, and the guide portion extends into the receiving cavity, the airflow force generated by the negative pressure when the adsorption mechanism is opened can generate a component force perpendicular to the opening direction of the receiving opening, causing the ferromagnetic metal debris to fall from the magnetic suction component into the receiving cavity for storage. This targeted cleaning method is more efficient than single-mode vacuum cleaners. This is because iron filings vary in size and shape. A single-mode vacuum cleaner needs a high suction force to pick up larger iron filings, but this generates a strong airflow. Smaller iron filings, being smaller, are more easily carried by this airflow, and changes in airflow direction or speed can cause them to scatter. Furthermore, iron filings of varying sizes are prone to collisions under high suction force. Smaller filings, being smaller, are more likely to change their motion after a collision, further scattering. In environments with a large amount of ferromagnetic metal debris, this application allows users to prioritize the first mode and adjust the magnetic force by controlling the current of the magnetic component. This optimizes the suction effect on different sizes and quantities of ferromagnetic metal debris in the first mode, quickly and centrally attracting the debris to the magnetic component. Afterward, the user can switch to the second mode to clean other dust and use negative pressure to attract ferromagnetic metal debris into the storage container. This reduces the pollution of the surrounding environment caused by ferromagnetic metal debris splashed during rail sawing and grinding operations, and improves the stability of the track equipment.

Abstract

The application relates to a dust suction device and relates to the technical field of machining equipment. When iron magnetic metal scraps need to be adsorbed, a controller controls the current of a magnetic suction piece to be increased, so that the magnetic suction piece can adsorb the iron magnetic metal scraps on the magnetic suction piece. Then, the controller controls the current of the magnetic suction piece to be reduced and an adsorption mechanism to be opened. Since the edge of the containing opening located on the side of the first wall away from the containing cavity is surrounded by a flow guide part, the flow guide part is arranged to extend towards the containing cavity, when the adsorption mechanism is opened, a component force perpendicular to the opening direction of the containing opening can be generated, so that the iron magnetic metal scraps fall from the magnetic suction piece to the containing cavity for storage. In this way, the user can preferentially use the first mode, quickly and centrally adsorb the iron magnetic metal scraps on the magnetic suction piece, and then switch to the second mode to clean other impurities and adsorb the iron magnetic metal scraps to the containing cavity by means of negative pressure, so as to reduce the pollution of the splashed impurities in the steel rail sawing and grinding operation to the surrounding environment and improve the stability of the line equipment.

The controller controls the adsorption mechanism to open. Since the edge of the receiving opening located on the side of the first wall opposite to the receiving cavity is surrounded by a guide portion, and the guide portion extends into the receiving cavity, the airflow force generated by the negative pressure when the adsorption mechanism is opened can generate a component force perpendicular to the opening direction of the receiving opening, causing the ferromagnetic metal debris to fall from the magnetic suction component into the receiving cavity for storage.

Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 This application shows a three-dimensional structural schematic diagram of the vacuuming device 100 in some embodiments. Figure 2 It shows Figure 1 This application provides a vacuum cleaner 100, including a housing component 1, a magnetic suction mechanism 3, a controller 4, and an adsorption mechanism.

[0039] The receiving component 1 includes a receiving body 11 and a flow guide 2. The receiving body 11 has a receiving cavity R and a receiving opening K communicating with the receiving cavity R. The shape and size of the receiving body 11 are not limited here. The receiving body 11 includes a first wall 111, and the receiving opening K is opened in the first wall 111. The flow guide 2 is provided around the edge of the receiving opening K on the side of the first wall 111 opposite to the receiving cavity R, and the flow guide 2 extends into the receiving cavity R. Thus, due to the special design of the flow guide 2, the airflow is guided by the flow guide 2 when it enters the receiving opening K, generating an airflow component force perpendicular to the mounting surface, which makes it easier to drag the ferromagnetic metal debris on the magnetic attraction mechanism 3 to the receiving opening K and drop it into the receiving cavity R.

[0040] Continue to refer to Figures 1 to 2 and in conjunction with reference Figure 3 , Figure 3 It shows Figure 1 The diagram shows a three-dimensional structure of the receiving component 1. The magnetic attraction mechanism 3 includes a magnetic attractor 31, which is located on the side of the first wall 111 opposite to the receiving cavity R, and near the receiving opening K at the edge of the first wall 111 opposite to the receiving cavity R. The magnetic attractor 31 is a magnetic component capable of attracting ferromagnetic metal debris to itself; specifically, it can be configured as an electromagnet. Positioning the magnetic attractor 31 near the receiving opening K at the edge of the first wall 111 opposite to the receiving cavity R makes it easier for the attracted ferromagnetic metal debris to be attracted to the receiving opening K.

[0041] The adsorption mechanism is a component that generates adsorption force. It has an adsorption channel that is connected to the receiving cavity R, so that the ferromagnetic metal debris on the magnetic suction component 31 is dragged to the receiving opening K and falls into the receiving cavity R.

[0042] The controller 4 is electrically connected to both the magnetic suction mechanism 3 and the adsorption mechanism. The controller 4 controls the operating state of the magnetic suction mechanism 3, controlling the current of the magnetic suction element 31 and the adsorption force of the adsorption mechanism. The controller 4 is the component that controls the magnetic suction element 31 and the adsorption mechanism; it is electrically connected to both. If the magnetic suction element 31 needs adjustment, the controller 4 sends a control signal to it via a wire. Upon receiving the signal, the magnetic suction element 31 adjusts its operating state accordingly. For example, it may energize the electromagnet to generate magnetic force to attract ferromagnetic metal debris, or adjust the magnetic force of the magnetic suction element 31. If the adsorption mechanism needs adjustment, the controller 4 sends a control signal to it via a wire. The motor of the adsorption mechanism adjusts its speed according to the control signal, changing the negative pressure within the adsorption channel, thereby increasing or decreasing the suction power.

[0043] The vacuum cleaner 100 includes at least a first mode and a second mode, and may also have other modes, which are not limited here. In the first mode, the magnetic force generated by the magnetic suction element 31, capable of attracting ferromagnetic metal debris, is greater than the adsorption force generated by the adsorption mechanism. The ferromagnetic metal debris can be stably attracted to the magnetic suction element 31.

[0044] When the vacuum cleaner 100 is in the second mode, the magnetic attraction force generated by the magnetic suction member 31, which is capable of attracting ferromagnetic metal debris, is less than the adsorption force generated by the adsorption mechanism, which is also capable of attracting ferromagnetic metal debris. The ferromagnetic metal debris can be dragged from the magnetic suction member 31 to the receiving opening K and fall into the receiving cavity R.

[0045] Thus, in environments with a large amount of ferromagnetic metal debris, users can prioritize the first mode and adjust the magnetic force by regulating the current of the magnetic component 31 via the controller 4. This optimizes the adsorption effect on ferromagnetic metal debris of different sizes and quantities, quickly and centrally attracting the debris to the magnetic component 31. Afterward, the user can switch to the second mode to clean other dust and use negative pressure to adsorb ferromagnetic metal debris into the receiving cavity R. This targeted cleaning is more efficient than a single-mode vacuum cleaner because metal debris varies in size and shape. A single-mode vacuum cleaner requires a high adsorption force to adsorb larger metal debris, but this high force generates a strong airflow during adsorption. Small metal debris, being smaller, is more easily carried by the airflow, and if the direction or speed of the airflow changes, the small metal debris may be blown around. Furthermore, iron filings of varying sizes are prone to collision under strong adsorption forces. Smaller filings, due to their smaller mass, are more likely to change their motion after collision, leading to them scattering everywhere. In environments with abundant ferromagnetic metal debris, this application allows users to prioritize the first mode and adjust the current of the magnetic component 31 via the controller 4 to flexibly adjust the magnetic force. This optimizes the adsorption effect on ferromagnetic metal debris of different sizes and quantities in the first mode, quickly and centrally attracting the debris to the magnetic component 31. Afterward, the system can switch to the second mode to clean away other dust and use negative pressure to attract the ferromagnetic metal debris into the storage container 6. This reduces the pollution of the surrounding environment caused by ferromagnetic metal debris splashing during rail sawing and grinding operations, improving the stability of the track equipment.

[0046] In some embodiments of this application, reference continues to be made to... Figure 1 and Figure 3The flow guide 2 includes a first flow guide surface 21 connected to the edge of the receiving port K located on the side of the first wall 111 opposite to the receiving cavity R. The first flow guide surface 21 is arranged around the edge of the receiving port K located on the side of the first wall 111 opposite to the receiving cavity R. The cross-sectional area of ​​the first flow guide surface 21 gradually decreases along the direction from the axis of the receiving port K to the inside of the receiving cavity R. The cross-section of the first flow guide surface 21 is perpendicular to the direction from the axis of the receiving port K to the inside of the receiving cavity R.

[0047] As the gas flows into the receiving cavity R along the axial direction F1 of the receiving port K, the cross-sectional area of ​​the first guide surface 21 gradually decreases, causing the airflow velocity to gradually increase as it passes through the guide section 2. According to the continuity equation of fluids, for a constant flow rate, the flow velocity is inversely proportional to the cross-sectional area. The structure of the guide section 2 allows the airflow to enter the receiving cavity R more smoothly. Furthermore, because the cross-sectional area of ​​the first guide surface 21 gradually decreases, when the gas flows through the guide section 2, according to Bernoulli's principle, the increased flow velocity leads to a decrease in the static pressure of the gas. In an adsorption scenario, this pressure reduction is beneficial for enhancing the adsorption force.

[0048] In some embodiments of this application, reference continues to be made to... Figure 1 and Figure 3 Continue to refer to Figure 1 and Figure 3 and in conjunction with reference Figure 4 , Figure 4 It shows Figure 3 The diagram shows a front view of the receiving component 1. The flow guide 2 also includes a second flow guide surface 22 connected to the first flow guide surface 21; the second flow guide surface 22 is located downstream of the first flow guide surface 21 and extends along the direction from the axis of the receiving opening K into the receiving cavity R. The direction from the axis of the receiving opening K into the receiving cavity R is parallel to the axial direction F1 of the receiving opening K.

[0049] The second guide surface 22 forms a transition channel for ferromagnetic metal debris from the surface of the magnetic suction member 31 to the receiving cavity R. This allows the ferromagnetic metal debris to quickly enter the receiving cavity R along the transition channel after detaching from the magnetic suction member 31, effectively preventing the accumulation and blockage of ferromagnetic metal debris at the corner of the guide section 2, and ensuring the high efficiency and smoothness of ferromagnetic metal debris transfer.

[0050] In the second mode, the tangential component of the airflow is further converted into a spiral centripetal force along the second guide surface 22, which pushes the ferromagnetic metal debris to rotate and slide down in close contact with the second guide surface 22. This reduces the risk of the ferromagnetic metal debris being recaptured by the magnetic attractor 31 after it has detached from the magnetic attractor 31, and improves the guiding accuracy and conveying efficiency of the airflow for the ferromagnetic metal debris.

[0051] In some embodiments of this application, reference continues to be made to... Figures 1 to 3 The second guide surface 22 is constructed as a cylindrical surface.

[0052] The second guide surface 22 adopts a cylindrical design. When the ferromagnetic metal debris moves on the second guide surface 22, it is only subjected to tangential friction force, which prevents local jamming caused by impact resistance and effectively solves the problem of ferromagnetic metal debris getting stuck in the gap, making the transfer of ferromagnetic metal debris smoother.

[0053] In some embodiments of this application, reference continues to be made to... Figures 1 to 3 The outer wall of the housing body 11 is provided with a groove C, and the bottom wall of the groove C forms the first wall 111.

[0054] When a groove C is provided on the outer wall of the containment body 11, and the bottom wall of the groove C constitutes the first wall 111, when the containment body 11 collides with the outside, since the first wall 111 is the bottom wall of the groove C, the side wall of the groove C will contact the outside first, thus preventing the risk of damage to the first wall 111.

[0055] In addition, a second groove is provided on the first wall 111. The second groove physically limits the magnetic suction component 31, so that the position of the magnetic suction component 31 is relatively fixed after installation, thus realizing that the magnetic suction force of the magnetic suction component 31 acting on the receiving port K area is stable and controllable.

[0056] Furthermore, the second groove can be connected to the receiving opening K, making it easier for ferromagnetic metal debris to fall from the magnetic attractor 31 to the receiving opening K.

[0057] Furthermore, the depth of the second groove can be set to be greater than the thickness of the magnetic member 31, so that the magnetic surface of the magnetic member 31 is located below the mounting surface, thereby making it difficult for non-ferromagnetic metal debris and impurities to directly cover the surface of the magnetic member 31 and maintain the magnetic attraction efficiency.

[0058] With multiple magnetic attractors 31 arranged around the edge of the receiving opening K on the side of the first wall 111 facing away from the receiving cavity R, a strong magnetic field network is uniformly covered in the circumferential space of the receiving opening K. This ensures that ferromagnetic metal debris can be captured by the magnetic force generated by at least one sub-magnetic attractor 31 regardless of the direction from which it approaches the receiving opening K, thus improving the efficiency of the magnetic attractors 31 in attracting ferromagnetic metal debris. The multiple magnetic attractors 31 serve as backups for each other, ensuring that even if one magnetic attractor 31 fails, the remaining magnetic attractors 31 can still provide magnetic attraction to ferromagnetic metal debris.

[0059] The aforementioned "the outer wall of the receiving body 11 has a groove C, the bottom wall of the groove C forms the first wall 111" and "multiple magnetic suction members 31 are provided, and all magnetic suction members 31 are arranged around the edge of the receiving opening K on the side of the first wall 111 opposite to the receiving cavity R", can be combined arbitrarily according to the actual situation.

[0060] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The cross-sectional area of ​​the receiving cavity R decreases along the axis of the receiving opening K, pointing towards the inside of the receiving cavity R; the cross-section of the receiving cavity R is perpendicular to the axis of the receiving opening K and points towards the inside of the receiving cavity R.

[0061] Thus, as the cross-sectional area of ​​the receiving cavity R decreases along the axis pointing from the receiving port K into the receiving cavity R, according to Bernoulli's principle, with a constant airflow velocity, the static pressure of the gas increases accordingly as the cross-sectional area decreases. During the adsorption process, when the adsorbed object approaches the receiving port K, this increased static pressure generates a stronger adsorption force, thereby accelerating the detachment of ferromagnetic metal debris from the magnetic attractor 31 in the second mode.

[0062] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The direction along the axis of the receiving opening K points into the receiving cavity R, and the cross-sectional area of ​​the receiving cavity R remains unchanged at first and then gradually decreases.

[0063] Thus, with the initial cross-sectional area of ​​the receiving cavity R remaining unchanged, the airflow can enter at a relatively stable velocity and pressure. At this time, the airflow has a certain buffer space in the region with a constant cross-sectional area, allowing it to initially adjust its flow state and reduce airflow fluctuations caused by external airflow interference at the receiving port K or sudden entry into a narrow space, preventing the risk of metal filings scattering. Furthermore, the portion of the receiving cavity R with a constant cross-sectional area reduces the risk of collision between the guide section 2 and the receiving body 11 during installation.

[0064] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The adsorption mechanism also includes a storage component 6 and a conveying component 5, with the conveying component 5 connected to the housing body 11 and the storage component 6.

[0065] Storage component 6 is a component for storing and collecting impurities. It has a receiving cavity that is connected to the receiving port K, through which the impurities are collected in the receiving cavity.

[0066] In addition, the housing body 11 may include a base and a cover plate covering the base. The cover plate and the base are detachably connected. The first wall 111 is located on the cover plate. This makes it easier to maintain and clean impurities in the housing cavity R. The detachable method is not limited. It can be a threaded connection or a snap-fit ​​connection. There are no restrictions here.

[0067] By providing the conveyor 5, the physical distance between the receiving component 1 and the storage component 6 is increased. In this way, during the process of the magnetic suction component 31 on the cover attracting magnetic metal debris and the process of impurities being attracted through the receiving port K, impurities are less likely to adhere to the storage component 6 and other components.

[0068] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The conveying component 5 includes a first conveying part 61 connected to the receiving body 11, a second conveying part 62 connected to the storage component 6, and a bending part 63 connecting the first conveying part 61 and the second conveying part 62; wherein the extension direction of the first conveying part 61 and the extension direction of the second conveying part 62 are both parallel to the axial direction F1 of the receiving opening K, and the extension direction of the bending part 63 intersects with the axial direction F1 of the receiving opening K.

[0069] The extension directions of the first conveying section 61, the second conveying section 62, and the axial direction F1 of the receiving port K are arranged in parallel. The airflow passes through the receiving port K, the first conveying section 61, and the second conveying section 62 in the same direction, allowing the airflow to pass smoothly. The vortex generated by the bending section 63 will generate a rotating airflow, causing the impurities to be subjected to airflow from multiple directions during the conveying process, forming a suspension effect. This reduces the direct contact between the impurities and the inner wall of the pipe, reduces friction, and makes it easier for ferromagnetic metal fragments to be carried by the airflow, thereby improving the efficiency of conveying impurities from the receiving component 1 to the storage component 6.

[0070] In addition, this application also includes a remote control equipped with a wireless transmitting module and a controller 4 equipped with a wireless receiving module. The controller 4 is electrically connected to the adsorption mechanism and the magnetic attractor 31, and is used to adjust the current of the magnetic attractor 31. Specifically, when the operator presses a button on the wireless remote control, the built-in wireless transmitting module encodes the user's operation command into a wireless signal and transmits it. The built-in wireless receiving module of the controller 4 receives the signal sent by the wireless remote control, analyzes the received wireless signal, and identifies the user's specific command, such as energizing the electromagnet or adjusting the magnetic power. If the magnetic attractor 31 needs to be adjusted, the controller 4 sends a control signal to the magnetic attractor 31 via a wire. After receiving the control signal, the magnetic attractor 31 adjusts its working state according to the signal command. For example, energizing the electromagnet causes it to generate magnetic force to attract ferromagnetic metal debris, or adjusting the magnetic force of the magnetic attractor 31. If the adsorption mechanism needs to be adjusted, the controller 4 sends a control signal to the adsorption mechanism via a wire. The motor of the adsorption mechanism adjusts its speed according to the control signal, changing the negative pressure in the main ventilation channel, thereby enhancing or weakening the dust collection ability.

[0071] The vacuuming device 100 also includes a frame 7, a rolling element 8, and a support element 9; the storage element 6 and the controller 4 are both disposed on the frame 7, the rolling element 8 is rotatably connected to the bottom of the frame 7 in a controllable manner, and the support element 9 is disposed at the bottom of the frame 7.

[0072] The heavier and less easily moved components, such as the storage unit 6 and the controller 4, are placed on the frame 7. The rolling element 8 and the support element 9 are located at the bottom of the frame 7, allowing the vacuum cleaner 100 to be moved to the desired location at any time. Although the rolling element 8 provides good mobility, the stability of the equipment is crucial when suction operations are required. Therefore, the design includes a support element 9 at the bottom of the frame 7. In the working state, the support element 9 rests against the ground, effectively preventing the frame 7 from sliding and making the vacuum cleaner 100 more stable during operation.
