[0035] Please refer to Figures 1-6 , the present invention provides a multifunctional magnetic attraction limit and stop structure, including a hose assembly 1, a floor brush main body 2, a shrapnel wire assembly 3, a magnet 4, a magnetic attraction block 5 and a linkage switch 6. The hose assembly 1 is rotatably connected to the floor brush main body 2. Two shrapnel wire assemblies 3 are arranged in the hose assembly 1. The magnet 4 is arranged between the two shrapnel wire assemblies 3. The magnet 4 is connected to the hose assembly 1. The magnetic attraction block 5 is arranged below the magnet 4. The magnetic attraction block 5 is connected to the linkage switch 6. The linkage switch 6 is arranged in the floor brush main body 2. When the hose assembly 1 is upright, the magnet 4 and the magnetic attraction block 5 are on the same straight line. The magnet 4 pulls the magnetic attraction block 5 upward and is clamped on the hose assembly 1. The magnetic attraction block 5 and the two shrapnel wire assemblies 3 form a closed loop. When the linkage switch 6 is pressed, the magnetic attraction block 5 disengages from the magnet 4, and the hose assembly 1 can be disengaged from the upright state.

[0036] The magnet 4 is a non-conductive magnet, which can prevent the magnet from connecting the two shrapnel wire assemblies and causing misjudgment.

[0037] The hose assembly 1 includes a housing 11 and a hose 12 built in the housing 11. An installation bracket 7 is arranged on the housing 11. A card slot 71 is arranged on the installation bracket 7. The magnet 4 is clamped in the card slot 71. This facilitates the installation and disassembly of the magnet and reduces the installation difficulty of the magnet.

[0038] A through hole 8 is provided at the bottom of the housing 11. The size of the through hole 8 is matched with the magnetic attraction block 5, and the through hole 8 is located below the magnet 4. This facilitates the entry and exit of the magnetic attraction block from the housing and its clamping at the through hole, achieving the purpose of fixing the hose assembly. To further fix the magnetic attraction block, a pressing block 9 is provided on the side wall of the through hole. As shown in Figure 6 , the pressing block is connected to an installation cavity opened on the side wall of the through hole by a spring. When the magnetic attraction block enters the through hole by itself, the pressing block comes into contact with the magnetic attraction block, making the fixation of the magnetic attraction block more firm.

[0039] First stop blocks 72 are respectively provided on both sides of the mounting bracket 7. A second stop block 73 is provided below the first stop block 72. The second stop block 73 is connected to the housing 11. A gap through which the elastic sheet wire assembly 3 passes is left between the second stop block 73 and the first stop block 72. The elastic sheet wire assembly 3 includes a wire 31 and an elastic sheet 32. The elastic sheet 32 is inserted into the gap, and the elastic sheet 32 is connected to one end of the wire 31. This can prevent the elastic sheet from moving and make the contact between the elastic sheet and the magnetic attraction block more stable.

[0040] An installation groove 61 is provided on the linkage switch 6, and the magnetic attraction block 5 is installed in the installation groove 61.

[0041] A button 62 is provided on the linkage switch 6, and the button 62 extends out of the surface of the floor brush body 2. A spring is provided between the button and the floor brush body, which can reset the linkage switch, so that the housing can press against the magnetic attraction block to prevent the magnetic attraction block from entering the through hole by itself.

[0042] Working principle: By installing a strong magnet on the hose part of the vacuum cleaner hose assembly and a magnetizable magnetic attraction block at the corresponding position of the floor brush body, the magnetic attraction block is conductive. When the hose assembly rotates with the main body to be perpendicular to the floor brush body at 90 degrees, the magnet and the magnetic attraction block are on the same straight line, and the magnet and the magnetic attraction block attract each other. The magnetic attraction block on the floor brush body is pulled up and inserted into the through hole to form a closed clamping, realizing the limit of the hose assembly. At this time, the magnetic attraction block and the two elastic sheet wire assemblies form a complete circuit, so that the power supply of the vacuum cleaner main body senses power here and immediately stops the rotation of the floor brush body and stops working; when the linkage switch on the floor brush is stepped on, the magnetic attraction block is separated from the magnet, and the hose assembly can rotate a certain angle and is in the working state. The circuit composed of the two elastic sheet wire assemblies is disconnected, and the power supply of the vacuum cleaner main body supplies power to the floor brush body, and the floor brush body resumes normal work.

[0043] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
