[0034] In addition, if the terms "horizontal" or "vertical" appear in the description of this application, it does not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Embodiment 1: A magnetic filter comprises a tube cover 1, the top of the tube cover 1 is fixedly connected to a motor 2, the driving end of the motor 2 is fixedly connected to a stirring rod 3, the outer wall of the stirring rod 3 is provided with a plurality of grooves, the outer wall of the stirring rod 3 is provided with a plurality of magnetic blades 4, the inner wall of the stirring rod 3 is fixedly connected to a spring bar 5, the end of the spring bar 5 is fixedly connected to a limiting rod 6, the outer wall of the limiting rod 6 is slidably connected to the inner wall of the stirring rod 3, the outer wall of the limiting rod 6 is penetrated on the inner wall of the magnetic blade 4, the outer wall of the limiting rod 6 is fixedly connected to a push rod 7, the outer wall of the push rod 7 is slidably connected to the inner wall of the stirring rod 3, and the outer wall of the stirring rod 3 is evenly provided with three magnetic blades 4.

[0037] Specifically, the motor 2 is started to drive the stirring rod 3 to rotate, and the rotation of the stirring rod 3 drives the three magnetic blades 4 on its outer wall to rotate, thereby performing large-scale stirring and adsorption of the magnetic substance in the liquid entering the main pipe 18. When the surface of the magnetic blade 4 is saturated with adsorption, the push rod 7 can be pushed to drive the spring bar 5 to be pressed, thereby driving the limiting rod 6 to leave the inner wall of the magnetic blade 4, so that the magnetic blade 4 can be easily removed and replaced with a new magnetic blade 4. This part of the structure is mainly for explaining the liquid magnetic filtration link. Compared with the previous permanent magnet bar to adsorb impurities, this structure is more complete for the magnetic filtration of liquids and has a better filtration effect.

[0038] Embodiment 2: A rubber ring 17 is fixedly connected to the bottom end of the pipe cover 1, a limit plate 8 is fixedly connected to the outer wall of the pipe cover 1, a limit rod 9 is arranged on the top of the limit plate 8, a handle 10 is rotatably connected to the outer wall of the limit rod 9, a positioning rod 12 is rotatably connected to the inner wall of the handle 10, a positioner 11 is fixedly connected to the outer wall of the positioning rod 12, and a main pipe 18 is fixedly connected to the outer wall of the positioner 11.

[0039] Specifically, when the filtration is completed and the pipe needs to be cleaned or the magnetic sheet needs to be replaced, the handles 10 on both sides of the main pipe 18 are rotated along the positioning rod 12, thereby driving the limit rod 9 to disengage from the limit plate 8, and the pipe cover 1 can be removed, the inside of the main pipe 18 can be cleaned or the magnetic leaf 4 can be replaced. In addition, the rubber ring 17 has a good anti-leakage effect in such a structure, which provides convenience for operation without affecting the function. The structure of this part is mainly for the explanation of the disassembly link of the magnetic filter. Compared with the previous screw fixing, this structure is more convenient and simple to operate.

[0040] Embodiment 3: The outer wall of the main pipe 18 is fixedly connected with the feed pipe 13 , the outer wall of the main pipe 18 is fixedly connected with the discharge pipe 14 , the inner wall of the discharge pipe 14 is fixedly connected with the spring sheet 15 , and the outer wall of the spring sheet 15 is clamped with a filter screen 16 .

[0041] Specifically, the liquid enters the main pipe 18 from the feed pipe 13, and after magnetic filtration, the liquid is filtered by the filter screen 16 and then discharged from the discharge pipe 14. When too many impurities are adsorbed on the surface of the filter screen 16, the spring sheet 15 can be swung to easily remove and replace the filter screen 16. This part of the structure mainly explains the specific direction of the liquid. Compared with the previous magnetic filter, this structure will filter the non-magnetic substances in the liquid to a certain extent, so that the liquid output from the discharge pipe 14 can be better used by the user.

[0042] Working principle: first, the liquid enters the main pipe 18 from the feed pipe 13, and then the motor 2 is started, thereby driving the stirring rod 3 to rotate. The rotation of the stirring rod 3 drives the three magnetic leaves 4 on its outer wall to rotate, thereby performing large-scale stirring and adsorption of the magnetic substance in the liquid entering the main pipe 18, and then the liquid is filtered through the filter net 16 and discharged from the discharge pipe 14. Then, when the surface of the magnetic leaf 4 is saturated with adsorption, the handles 10 on both sides of the main pipe 18 are rotated along the positioning rod 12, thereby driving the limit rod 9 to disengage from the limit plate 8, and the pipe cover 1 can be removed, and then the push rod 7 is pushed to drive the spring bar 5 to be pressed, thereby driving the limit rod 6 to leave the inner wall of the magnetic leaf 4, so that the magnetic leaf 4 can be easily removed, and the inside of the main pipe 18 can be cleaned or the magnetic leaf 4 can be replaced.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
