It should be noted that, in the absence of conflict, the features in the embodiments of the present application can be combined with each other.

[0024] The following description sets forth many specific details to facilitate a full understanding of the embodiments of the present invention. The embodiments described are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the embodiments of the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See also Figures 1 to 3 The present application provides a magnetic material adsorption device 100, which includes an iron core 1, a sleeve 2 and a mounting portion 3. The sleeve 2 is sleeved on the iron core 1, and both ends of the iron core 1 are rotatably mounted on the mounting portion 3.

[0027] The mounting portion 3 is generally U-shaped and includes a first frame 31, a second frame 32, and fasteners 33. The first frame 31 and the second frame 32 are fixedly connected by the fasteners 33. The first frame 31 includes a first connecting portion 311 and a first side panel 312. The first side panel 312 is obliquely connected to one side of the first connecting portion 311. The second frame 32 includes a second connecting portion 321 and a second side panel 322. The second side panel 322 is obliquely connected to one side of the second connecting portion 321. A first fixing hole 34 is defined at the end of the first connecting portion 311 facing away from the first side panel 312. A second fixing hole 35 corresponding to the position of the first fixing hole 34 is defined at the end of the second connecting portion 321 facing away from the second side panel 322. Each fastener 33 can pass through the first fixing hole 34 and the corresponding second fixing hole 35 to securely connect the first frame 31 and the second frame 32. The first side panel 312 includes a first positioning hole 36, and the second side panel 322 includes a second positioning hole 37 corresponding to the position of the first positioning hole 36. A groove 3111 is provided at the end of the first connecting portion 311 away from the first side plate 312. The groove 3111 is used to accommodate part of the second connecting portion 321. The first fixing hole 34 passes through the bottom of the groove 3111, so that when the fastener 33 fixes the first frame body 31 and the second frame body 32, the part of the second connecting portion 321 away from the second side plate 322 is accommodated in the groove 3111.

[0028] The first connecting portion 311 includes a first outer surface 3121, a first inner surface 3122, and multiple side surfaces connected between the first outer surface 3121 and the first inner surface 3122. The second connecting portion 321 includes a second outer surface 3221 that faces away from the first connecting portion 311. The groove 3111 passes through the first outer surface 3121 and the three adjacent side surfaces, so that when the end of the second side plate 322 is accommodated in the groove 3111, the second outer surface 3221 is flush with the first outer surface 3121.

[0029] The core 1 includes a main body and connecting ends 1b, which are disposed at opposite ends of the main body. The diameter of the connecting ends 1b is smaller than that of the main body. The sleeve 2 is fitted over the core 1, exposing portions of the connecting ends 1b at opposite ends of the core 1. The exposed portions of the connecting ends 1b at opposite ends of the core 1 are rotatably mounted within the first and second positioning holes 36 and 37, respectively, allowing the core 1 to be rotatably mounted on the mounting portion 3.

[0030] When installing the iron core 1, align the first fixing hole 34 of the first connecting portion 311 with the second fixing hole 35 of the second connecting portion 321. The fastener 33 passes through the aligned first fixing hole 34 and second fixing hole 35 to securely connect the first frame 31 and the second frame 32. At this point, one connecting end 1b of the iron core 1 passes through the first positioning hole 36, and the other connecting end 1b of the iron core 1 passes through the second positioning hole 37. The first side plate 312 and the second side plate 322 rotate the iron core 1 to the first frame 31 and the second frame 32. As a result, the iron core 1 and the sleeve 2 are securely mounted on the mounting portion 3. By gripping the grip 5, the user can cause the sleeve 2 to roll, and the iron core 1 also rolls, with its connecting end 1b rotating within the corresponding positioning hole, thereby attracting magnetic foreign matter on the ground to the surface of the sleeve 2.

[0031] When the core 1 needs to be removed, the fastener 33 is loosened and disengaged from the first fixing hole 34 and the second fixing hole 35. The first frame 31 and the second frame 32 are then separated from each other for a distance. At this time, the core 1 and the sleeve 2 can be removed from the mounting portion 3. The sleeve 2 is then separated from the core 1, allowing the core 1 to be replaced or the surface of the sleeve 2 to be cleaned. The inner diameter of the sleeve 2 is slightly larger than the outer diameter of the core 1, allowing the two to be separably mounted.

[0032] In some embodiments, the magnetic material adsorption device 100 further includes rollers 4, which are mounted on opposite ends of the sleeve 2. When the magnetic material adsorption device 100 is used to clean the floor, the rollers 4 can help the core 1 and the sleeve 2 roll on the floor, thereby increasing the contact area between the sleeve 2 and the magnetic material, thereby improving the adsorption capacity of the magnetic material adsorption device 100.

[0033] In some embodiments, the core 1 is made of a neodymium iron boron magnet and the sleeve 2 is made of stainless steel. The use of neodymium iron boron magnets allows the core 1 to have a magnetic field strength of approximately 12,000 gauss, and the magnetic field strength at ground level can reach 5,000 gauss, effectively enhancing the magnetic material adsorption device 100's ability to adsorb magnetic impurities and improve its cleaning capabilities.

[0034] In some embodiments, the difference in radius between the sleeve 2 and the roller 4 is 4 mm to 6 mm. Reducing the difference in radius between the sleeve 2 and the roller 4 helps reduce the distance between the core 1 and the ground, further improving the magnetic material adsorption device 100's adsorption force on the magnetic material, enabling more comprehensive adsorption of magnetic impurities on the ground and enhancing the cleaning ability of the magnetic material adsorption device 100.

[0035] In some embodiments, the fastener 33 may be a screw or a bolt.

[0036] In some embodiments, there are two fasteners 33. The first frame 31 includes two first fixing holes 34, and the second frame 32 includes two second fixing holes 35. Each first fixing hole 34 is aligned with a corresponding second fixing hole 35. The fastener 33 passes through the aligned first fixing holes 34 and second fixing holes 35 to secure the first frame 31 and the second frame 32. It is understood that in other embodiments, the number of fasteners 33 may be one, three, four, five, etc. The present invention does not impose any particular limitation on the number of fasteners 33.

[0037] In some embodiments, the magnetic material adsorption device 100 further includes a gripping portion 5, which is connected to the mounting portion 3 via a fixed connector 6, which is disposed within the gripping portion 5. In this embodiment, the mounting portion 3 is provided with a mounting hole in the area where the mounting portion 3 and the gripping portion 5 meet, and the gripping portion 5 is provided with a threaded hole. The fixed connector 6 is passed through the mounting hole in the mounting portion 3 and fixedly connected to the threaded hole in the gripping portion 5, thereby connecting the gripping portion 5 to the mounting portion 3. It is understood that in other embodiments, the gripping portion 5 can also be connected to the mounting portion 3 by welding or other methods.

[0038] In some embodiments, the grip portion 5 is provided with a handle 51 and a telescopic rod 52, and the telescopic rod 52 is connected to one end of the handle 51. The telescopic rod 52 is provided on the grip portion 5, and the length of the telescopic rod 52 is flexibly adjustable. The length of the magnetic material adsorption device 100 can be quickly adjusted according to the height of the user, making it easier for the user to use the magnetic material adsorption device 100.

[0039] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application should not depart from the spirit and scope of the technical solutions of the present application.
