Description

Technical Field

[0001] This utility model relates to a cleaning device, and more particularly to a magnetic cleaner for cleaning small metal objects that have fallen into production and processing sites, warehouses, or outdoor locations. Background Technology

[0002] In production and processing sites, warehouses, or outdoor areas, small metal scraps, such as iron filings, metal pieces, screws, rivets, and nuts, which are magnetically attracted, often fall onto the floor or ground, forming litter. Although the quantity may not be large, and they can even be picked up manually, the wide area involved makes manual searching and picking them up tedious, time-consuming, labor-intensive, and inefficient. Furthermore, some of these fallen objects may have sharp edges, posing safety hazards or affecting the cleanliness and tidiness of the site and normal production progress. Utility Model Content

[0003] This utility model provides a magnetic cleaner to address the problem that small, magnetically adsorbable metal objects often fall into production and processing sites, warehouses, or outdoor areas, making the search and retrieval process cumbersome, time-consuming, labor-intensive, and inefficient. This can even negatively impact the cleanliness and tidiness of the site and disrupt normal production progress. The cleaner offers a simple, convenient, and efficient solution that saves time and effort, effectively maintaining a clean and tidy environment and ensuring normal production progress.

[0004] The specific technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a magnetic cleaner, characterized in that it includes a magnetic lifting and accommodating cavity and a handle. The horizontally arranged magnetic lifting and accommodating cavity is provided with a permanent magnet and a magnetic lifting component. The bottom end of the magnetic lifting component is connected to a permanent magnet. The top end of the magnetic lifting and accommodating cavity is connected to a top connecting plate and a handle. The top connecting plate has a through hole for the lifting rod of the magnetic lifting component to freely move up and down. The top connecting plate has a handle connecting screw, and the handle and the handle connecting screw are threadedly connected. The two ends of the magnetic lifting and accommodating cavity are provided with lifting components. The bottom surface of the outer end of the magnetic lifting and accommodating cavity is higher than the bottom of the lifting components. The bottom surface of the outer end of the magnetic lifting and accommodating cavity is the magnetic adsorption surface of the bottom of the cleaner. After the magnetic lifting component and the permanent magnet fall freely downwards, the magnetic adsorption surface adsorbs small metal objects. After the magnetic lifting component lifts the permanent magnet upwards, the small metal objects automatically fall off the magnetic adsorption surface. The handle allows for flexible movement of the horizontally mounted magnet lifting and accommodating chamber during cleaning. The magnet lifting mechanism easily lowers the permanent magnet within the chamber to attract small, magnetically adsorbable metal objects, or lifts it upwards to detach the objects and allow them to fall automatically. This facilitates quick and easy cleaning of fallen objects, resulting in a simple, convenient, and efficient process that saves time and effort, effectively maintaining a clean and tidy workspace and supporting normal production. The handle is threadedly connected to a screw, ensuring effective magnetic adsorption and collection of small, magnetically adsorbable metal objects while minimizing the need for disassembly, thus facilitating convenient storage, packaging, and transportation of the product.

[0005] Preferably, the magnet lifting component includes a lifting rod and a top handle. A permanent magnet is located below the bottom of the lifting rod, and the top handle is connected to the top of the lifting rod. The top handle can be a horizontal, straight handle perpendicular to the lifting rod, or a hook-shaped handle or an arc-shaped closed-hole handle. This improves the ease, convenience, flexibility, and effectiveness of the magnet lifting component in lifting and lowering the permanent magnet.

[0006] Preferably, the magnetic lifting and accommodating cavity adopts a rectangular cavity structure or a long trapezoidal cavity structure, with the bottom surface of the horizontally arranged rectangular or long trapezoidal cavity serving as the magnetic adsorption surface at the bottom of the cleaner. This improves the simplicity, convenience, and effectiveness of using the bottom surface of the magnetic lifting and accommodating cavity to adsorb or separate small magnetically adsorbed metal objects.

[0007] Preferably, both ends of the horizontally positioned magnet lifting and accommodating cavity are equipped with slot-sealing plates, and a threaded connection hole is located at the center of the slot-sealing plate. The lifting component is threadedly connected to the threaded connection hole via a connecting screw. This improves the reliability, stability, and effectiveness of the lifting component's overall lifting and installation connection of the horizontally positioned magnet lifting and accommodating cavity, and enhances the ease and convenience of adsorbing or separating small magnetically adsorbed metal objects from the bottom surface of the magnet lifting and accommodating cavity. The resulting detachable lifting component reduces the space required for product storage and packaging during transportation.

[0008] Preferably, the lifting component uses rollers or bearings, with the bottom surface of the rollers or bearings positioned below the magnetic adsorption surface. This creates a height gap between the bottom surface of the lifting magnet accommodating cavity and the surface of the cleaning area, improving the ease and effectiveness of adsorbing or separating small, magnetically adsorbable metal objects from the bottom surface of the lifting magnet accommodating cavity.

[0009] Preferably, the top connecting plate base is made of a metal structure that can be attracted by a magnet. This includes structures made of iron, cobalt, nickel, or their alloys. This improves the effectiveness of the top connecting plate base in attracting permanent magnets, and ensures that the permanent magnet remains attached to the back of the top connecting plate base after the top handle is raised. This also improves the reliability and effectiveness of separating small, magnetically attracted metal objects originally attached to the bottom surface of the accommodating cavity.

[0010] Preferably, the handle is a telescopic handle structure. When fully retracted, the total length of the telescopic handle is -1cm to 7cm longer than the total length of the horizontally positioned magnet lifting and accommodating cavity. The bottom of the handle has a threaded connection section, with a telescopic section connected to the upper part of this threaded connection section. The handle is threadedly connected to the handle connecting screw on the top connecting plate via the bottom threaded connection section. The top of the handle has a grip section to increase friction and comfort. This improves the ease of disassembly and storage of the entire magnetic cleaner, reduces storage space requirements, and reduces packaging and transportation space requirements. It also improves the simplicity, stability, reliability, and effectiveness of the handle connection, and enhances the ease, flexibility, stability, reliability, and effectiveness of its operation.

[0011] Preferably, the bottom end of the magnet lifting component is connected to a magnet mounting and fixing base. The permanent magnets are installed within the magnet mounting and fixing base using a multi-piece dispersed installation structure or a single-piece integral installation and fixing structure. The permanent magnets are distributed along the length of the horizontally positioned magnet lifting and accommodating cavity. This improves the stability, reliability, and effectiveness of the permanent magnet installation and fixing, and enhances the reliability and effectiveness of adsorption or separation of small, magnetically adsorbable metal objects.

[0012] Preferably, the length of the horizontally positioned magnetic lifting and accommodating cavity is 40±10cm. This miniaturized magnetic cleaner is more conducive to improving the adsorption and separation of small, magnetically adsorbable metal objects, making cleaning easier, more flexible, and more effective, increasing efficiency, and avoiding the laborious work caused by heavy items.

[0013] Preferably, the handle connecting screw and the handle connected to it, along with the lifting rod of the magnetic lifting component, are inclined relative to each other. This improves the ease and effectiveness of operation between the handle and the magnetic lifting component, enhancing operational flexibility and efficiency.

[0014] The beneficial effects of this utility model are as follows: The horizontally positioned magnet lifting and accommodating chamber can be flexibly moved using the handle for cleaning and sweeping in the required area. The permanent magnet inside the chamber can be easily lowered using the magnet lifting component to attract small, magnetically adsorbable metal objects, or lifted upwards to automatically separate the objects from the magnetic adsorption surface. This allows for easy and quick cleaning of the area, making the cleaning process simple, convenient, efficient, time-saving, and labor-saving, effectively maintaining a clean and tidy environment and normal production progress. The handle and connecting screw are threaded together, ensuring the permanent magnet's magnetic adsorption and cleaning of small, magnetically adsorbable metal objects, as well as the collection of detached objects. This also effectively reduces the overall storage, packaging, and transportation space required after the handle is removed from the connecting screw. This improves the ease of disassembly and storage of the entire magnetic cleaner, reducing storage and packaging space requirements. Attached Figure Description

[0021] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In the illustrated embodiment, a magnetic cleaner includes a magnetic lifting and accommodating cavity 10 and a handle 40. A permanent magnet 91 and a magnetic lifting component are installed inside the horizontally positioned magnetic lifting and accommodating cavity 10. The bottom end of the magnetic lifting component is connected to the permanent magnet 91. A top connecting plate 30 and a handle 40 are connected to the top 13 of the horizontally positioned magnetic lifting and accommodating cavity. A through hole 31 is provided on the top connecting plate 30, through which the lifting rod 21 of the magnetic lifting component can freely move up and down. A handle connecting screw 70 is fixedly connected to the top connecting plate 30, and the handle 40 is threadedly connected to the handle connecting screw 70. Detachable lifting components 60 are installed and connected to both ends of the horizontally positioned magnetic lifting and accommodating cavity. The magnetic lifting and accommodating cavity is externally positioned... The bottom surface 12 is positioned higher than the lowest point of the lifting component 60. The bottom surface 12 of the horizontally positioned magnet lifting and receiving cavity is the magnetic adsorption surface of the bottom of the cleaner. After the magnet lifting component and the permanent magnet 91 fall freely downwards, the magnetic adsorption surface adsorbs small metal objects that can be magnetically attracted. After the magnet lifting component lifts the permanent magnet upwards, the permanent magnet 91 follows the lifting component and rises upwards within the cavity 15 of the horizontally positioned iron lifting and receiving cavity 10. The distance between the permanent magnet 91 and the bottom surface 12 of the iron lifting and receiving cavity increases. When the magnetic force of the permanent magnet 91 is insufficient to maintain the adsorption force on the small metal objects that can be magnetically attracted, the small metal objects that can be magnetically attracted separate from the magnetic adsorption surface (i.e., the bottom surface 12 of the outer casing of the magnet lifting and receiving cavity 10) and fall automatically. The height of the lifting rod 21 is greater than the height of the horizontally positioned iron lifting and receiving cavity 10. The top connecting plate base 30 has downward limiting flanges 32 that fold down from both sides of the plate base to lock the iron lifting and accommodating cavity 10 on both sides. The permanent magnet 91 is a permanent strong magnet structure.

[0022] The magnetic lifting component includes a lifting rod 21 and a top handle 20. A permanent magnet is located below the bottom of the lifting rod. The top handle 20 is fixedly connected to the top of the lifting rod 21. The top handle 20 can be a horizontal, straight handle perpendicular to the lifting rod, or a hook-shaped handle or an arc-shaped closed-hole handle. The horizontal, straight top handle 20 and the lifting rod 21 together form a T-shaped magnetic lifting component structure. The hook-shaped or arc-shaped closed-hole handle, together with the lifting rod 21, forms a hook-shaped magnetic lifting component structure with either a closed or open opening, enabling convenient, flexible, simple, and effective upward or downward lifting and lowering of the permanent magnet 91. The maximum height of the lifting rod 21 and its top handle 20 extending above the top connecting plate 30 is 6–8 cm; for example, 6 cm, 7 cm, or 8 cm can be used. While ensuring the magnetic adsorption and cleaning of small metal objects by permanent magnets, and the collection of any detached items, the system also effectively reduces the overall storage, packaging, and transportation costs of the product after the handle 40 is removed from the handle connecting screw 70. The horizontally positioned magnet lifting and accommodating cavity 10 adopts a rectangular cavity structure (see...). Figure 4 ) or a long trapezoidal groove cavity structure (see Figure 5 The bottom surface 12 of the horizontally arranged rectangular or trapezoidal cavity serves as the magnetic adsorption surface at the bottom of the cleaner. Both ends of the horizontally arranged magnetic lifting and accommodating cavity 10 are connected to slot-sealing plates 11, with threaded connection holes at their centers. The lifting component 60 is threadedly connected to these holes via connecting screws. The lifting component 60 uses rollers or bearings, with the bottom surface of the rollers or bearings positioned below the magnetic adsorption surface. The rollers are mounted on the outer sides of the slot-sealing plates 11 at both ends of the horizontally arranged magnetic lifting and accommodating cavity 10 via connecting studs 82, nuts 80, and spring washers 81. Nuts 80 and spring washers 81 are mounted between the rollers and the slot-sealing plates 11. The top connecting plate 30 is made of a metal structure that can be attracted by a magnet, including iron, cobalt, nickel, or their alloys.

[0023] The handle 40 is a telescopic handle structure. When fully retracted, the total length of the telescopic handle is -1cm to 7cm longer than the total length of the horizontally positioned magnet lifting and accommodating cavity. For example, the difference in length can be -1cm, 0cm, 2cm, 3cm, 4cm, 5cm, or 6cm. The telescopic handle 40 better meets the user's comfort and ensures reliable and effective cleaning when handling small, magnetically adsorbable metal objects. The handle can be extended to a suitable length according to actual needs. The bottom of the handle 40 has a threaded connection section 42, with a telescopic section 41 connected to the upper part of the threaded connection section 42. The handle 40 is threadedly connected to the handle connecting screw 70 on the top connecting plate 30 via the threaded connection section 42 at the bottom. The top of the handle 40 has a grip section 43 to increase friction and comfort. The handle grip section 43 is made of EVA or plastic material with a protective sleeve. The handle grip section 43 with the EVA or plastic material protective sleeve has a recessed arc-shaped groove to further improve the friction and comfort during use. The bottom of the magnetic lifting component is connected to a magnet mounting and fixing seat 90. The permanent magnets 91 are installed in the magnet mounting and fixing seat 90 using a multi-piece dispersed installation structure or a single-piece integral installation structure. The permanent magnets 91 are distributed along the length of the horizontally positioned magnet lifting and accommodating cavity 10. The cavity length of the horizontally positioned magnet lifting and accommodating cavity 10 is 40±10cm, for example, 40cm, 42cm, 45cm, 48cm, or 50cm. The cavity width of the horizontally positioned magnet lifting and accommodating cavity 10 is 5±1cm, for example, 4cm, 4.5cm, 5cm, 5.5cm, or 6cm. The handle connecting screw 70 and its connected handle 40 are inclined relative to the lifting rod 21 of the magnet lifting component. The inclination angle between them is 15º to 40º, for example, 15º, 20º, 30º, 35º or 40º.

[0024] When in use, to clean up small, magnetically adsorbable metal objects that have fallen or scattered in a relevant location, press down the top handle 20 of the magnet lifting component or let it fall naturally to the bottom. The permanent magnet will then follow the downward press of the top handle 20 to the bottom of the horizontally positioned magnet lifting and receiving cavity. Use the handle 40 to push or move the magnetic cleaner around the location. At this time, the magnetic force of the permanent magnet 91 in the cavity 15 of the horizontally positioned magnet lifting and receiving cavity 10 is sufficient to attract small, magnetically adsorbable metal objects scattered or fallen in the relevant location to the magnetic adsorption surface of the bottom of the outer groove of the magnet lifting and receiving cavity, which is the bottom of the cleaner, that is, to the bottom surface 12 of the outer groove of the magnet lifting and receiving cavity. Then, push or move the magnetic cleaner to the relevant position using the handle 40 to perform magnetic cleaning. After the collected small metal objects that can be magnetically attracted are moved to the corresponding position, they are separated and collected. When it is necessary to separate and collect the small metal objects that have been magnetically attracted and cleaned from the bottom surface 12 of the outer tank of the magnet lifting and receiving cavity, simply move the magnetic cleaner to the corresponding position with the handle, lift the top handle 20 of the magnet lifting component upwards, and lift it until the magnetic force of the permanent magnet 91 in the cavity 15 of the horizontally mounted iron lifting and receiving cavity is insufficient to maintain the attraction force on the small metal objects that have been magnetically attracted and cleaned. Then, the small metal objects that have been magnetically attracted and cleaned can fall directly from the bottom surface 12 of the outer tank of the magnet lifting and receiving cavity. This simple, easy and effective method achieves the magnetic attraction, cleaning and separation of small metal objects.
