DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figs. 1-4, an electric magnetic brush, comprising: inner brush 1 and outer brush 2, inner brush 1 and outer brush 2 are provided with shell 3 and magnet 4, inner brush 1 and outer brush 2 are attracted to each other by the magnetic force between magnet 4. Inner brush 1 is provided with brush surface 5 near the side of the fish tank, which can make the cleaning effect better, and the brush surface 5 can be: cloth, magic tape, rubber sheet, sponge, scouring pad, bristles. The magnet 4 in the shell 3 of the inner brush 1 and the outer brush 2 can be glued to the inner surface of the shell 3 of the inner brush 1 and the outer brush 2 near the side of the fish tank. The inner wall of the shell 3 of the inner brush 1 and the outer brush 2 plus the magnet fixing seat 7 can facilitate the placement of the magnet 4. It also includes a magnetic brush body 8, which is composed of a shell 9, a rotating source 10 and a power supply 11. The rotating source 10 can be: brush motor, brushless motor, brush motor, brushless motor. The rotating source 10 is fixedly installed in the magnetic brush body 8, and the rotating source output end 12 is connected with the outer brush 2, which can be fixedly connected or detachably connected or integrally connected. The end 13 of the rotating source output end is located inside the magnetic brush body shell 9, or a hole 14 is provided in the brush body shell 9, which extends to the outside of the magnetic brush body shell 9. The power supply 11 is electrically connected with the rotating source 10, and the power supply 11 is rechargeable battery or disposable battery or external adapter or wireless charging device, preferably the power supply 11 adopts rechargeable battery. The output end 12 of the rotating source 10 and the outer brush 2 can be integrally connected, glued or fixed with screws. A connecting card seat 15 is added to the side of the outer brush 2 near the fish tank, which can increase the fixity of the output end 12 of the rotating source 10 and the outer brush 2.

[0025] In this embodiment, the inner brush 1 is hollow inside, and the buoyancy of the inner brush 1 in water is greater than the gravity of the inner brush 1 in water, so that the inner brush 1 can float in water, which can make the inner brush 1 float on the water surface under the action of the buoyancy after the inner brush 1 and the outer brush 2 are separated from the magnetic constraint, and it is convenient to take back.

[0026] Please refer to Fig. 5, as an optional embodiment, the outer brush 2 is provided with a protrusion 16 near the side of the fish tank, which can reduce the contact area between the outer brush 2 and the fish tank, thereby reducing the friction between the outer brush 2 and the fish tank.

[0027] In this embodiment, the outer brush 2 is provided with a hair surface 6 near the side of the fish tank, which is used to clean the outer wall of the fish tank, and the hair surface 6 can be: cloth, magic tape, rubber sheet, sponge, scouring pad.

[0028] Please refer to Fig. 6, as an optional embodiment, the brush surface 5 of the inner brush 1 extends outward 5mm-50mm along the edge of the surface of the inner brush 1 near the side of the fish tank, which can clean the rounded corner part of the fish tank with rounded corners.

[0029] Please refer to FIG. 7 , as an optional embodiment, a bevel 17 is provided along the edge of the inner brush 1 near one end of the fish tank, and bristles 18 are provided on the bevel to clean the rounded corners of the fish tank.

[0030] In this embodiment, a PCBA 19 and a switch 20 can also be added. The PCBA 19 is fixedly installed in the magnetic brush body 10. The PCBA 19, switch 20, rotation source 10, and power supply 11 form an electrical circuit. The PCBA 19 can have charging, motor control, and boost functions. The housing 9 of the magnetic brush body 8 can be equipped with a charging port 23 for charging the rechargeable battery or directly supplying power to the PCBA 19 and rotation source 10. The switch is used to control the rotation source 10 to turn on or off or shift gears. The magnetic brush body housing 9 can be equipped with a charging port 21 to facilitate the connection of an external power supply to the PCBA 19 for charging or directly supplying power to the power supply 11. The magnetic brush body housing 9 can be equipped with a switch decorative member 22. The switch decorative member 22 faces the switch 20 and can transmit the pressure of a finger to the switch 20.

[0031] As an optional embodiment, a potentiometer may be added to adjust the rotation speed of the rotation source 10 , and the potentiometer is electrically connected to the PCBA 19 .

[0032] In this embodiment, the rotation source 10 adopts a brush reduction motor to increase the rotation torque and reduce the cost.

[0033] In this embodiment, the magnets 4 provided in both the inner brush 1 and the outer brush 2 can be one or more. The magnets 4 in the inner brush 12 and the magnets 4 in the outer brush 2 have opposite N and S polarities, which attract each other. The rotation source 10 drives the outer brush 2 to rotate, and the inner brush 1 is driven by the magnetic force of the outer brush 2, so the inner brush 1 also rotates. If multiple magnets 4 are provided in both the inner brush 1 and the outer brush 2, the transmission power can be increased. If only one magnet 4 is provided in each of the inner brush 1 and the outer brush 2, it can also be used, but the effect is slightly inferior. It is preferred to use multiple magnets. The magnetic poles of adjacent magnets 4 provided in the inner and outer brushes can be the same or opposite. When the magnetic force ranges of adjacent magnets 4 are adjacent, the opposite magnetic poles of adjacent magnets 4 can produce a push-pull effect. The magnets 4 between the inner brush 1 and the outer brush 2 attract each other with the same polarity, generating a pulling force, and repel each other with different polarities, generating a thrust force. This makes the relative position of the inner brush 1 and the outer brush 2 more stable during rotation, and the transmission effect is better. It is preferred to use magnets with opposite polarity. When the magnetic force ranges of adjacent magnets 4 are not adjacent, the magnets 4 of the inner brush 1 and the outer brush 2 can attract each other with the next magnet 4 after being misplaced, and preferably have the same magnetic poles.

[0034] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
