[0026] The following description is provided to enable any person skilled in the art to practice the application. The preferred embodiments described below are only examples of the application and other obvious modifications are possible.

[0027] In the application, the self-cleaning magnetic mobile filter core device is applied to filtering equipment, including but not limited to water purifying cups, water purifying filter bottles, hydraulic oil filters, and other liquid filtering equipment.

[0028] The filtering equipment necessarily includes the self-cleaning magnetic mobile filter core device, and in order to install the self-cleaning magnetic mobile filter core device into the filtering equipment, a mounting connecting pipe or cavity of the filter core device is provided.

[0029] Taking the application in a water purifying cup as an example, the self-cleaning magnetic mobile filter core device is installed in the water cup to achieve water purification, as shown in Figures 1-11 The following describes how the filter core seat 7 moves up and down along the inner wall of the cup body 2 under the action of the outer magnetic ring 9 and the inner magnetic ring 8 to achieve water purification operation; the self-cleaning magnetic mobile filter core device includes that the filter core seat 7 is installed in the cup body 2, the filter core seat 7 is provided with a cavity, a combined filter core 3 is installed in the cavity, the bottom of the filter core seat 7 is provided with a filter core replacement mechanism; the side surface of the filter core seat 7 is provided with a magnetic ring groove, the inner magnetic ring 8 is arranged longitudinally in the magnetic ring groove and can displace left and right in the magnetic ring groove; and the lowermost inner magnetic ring 8 is a cleaning brush plate 80; the side surface of the filter core seat 7 is provided with a semicircular groove hole 76 for installing and connecting the cleaning brush plate 80 of the bottommost inner magnetic ring 8; the bottom of the combined filter core 3 is connected with the cleaning brush plate 80.

[0030] As Figure 1 shown, the magnetic ring groove includes a first magnetic ring groove 7a, a second magnetic ring groove 7b, and a third magnetic ring groove 7c, and an inner magnetic ring 8 is installed in the magnetic ring groove. The inner magnetic ring 8 is composed of a pair of semicircular magnetic rings which are symmetrically clamped in the magnetic ring groove. The outer side wall of the filter core seat 7 is preliminarily sealed by the inner magnetic ring and the inner wall of the cup body 2 to prevent sewage from entering the clean water area. The inner magnetic ring 8 is tightly attached to the inner wall of the cup body 2 under the adsorption of the outer magnetic ring 9. The outer edge of the upper wall of the filter core seat 7 is further provided with a sealing film 77. When the inner magnetic ring 8 is installed, the three groups of inner magnetic rings 8 are staggered and stacked in the magnetic ring groove.

[0031] The design of the semicircular magnetic ring facilitates the installation of the filter core seat 7 and the inner magnetic ring 8, and the semicircular magnetic ring can be symmetrically clamped into the magnetic ring groove.

[0032] In order to ensure that the outer side wall and the inner wall of the cup body 2 are sealed during the up and down movement of the filter core seat 7, and prevent sewage from entering the clean water cavity, three groups of magnetic ring grooves are designed in this embodiment, and the three groups of magnetic ring grooves correspond to the inner magnetic ring 8.

[0033] The inner magnetic ring 8 is made of edible silica gel on the surface and a semicircular ring body solid magnet inside. Under the adsorption of the outer magnetic ring 9, it is tightly attached to the inner wall of the cup body 2, thereby realizing the water separation and sealing function. It should be noted that a small amount of water will leak from the gap area of the inner magnetic ring 8. When the inner magnetic ring 8 is installed, the magnetic ring gap area is staggered by 60 degrees and stacked in the first magnetic ring groove 7a, the second magnetic ring groove 7b, and the third magnetic ring groove 7c in sequence. A circle of sealing film 77 is provided at the circumferential edge of the filter core seat 7, and the sealing film 77 is used to completely isolate the small amount of sewage leaked from the gap area. It should be noted that the three groups of inner magnetic rings 8 are staggered and combined, which has two effects. One effect is to improve the magnetic force to facilitate the adsorption of the filter core seat 7 by the outer magnetic ring 9, thereby realizing the up and down movement. The other effect is to isolate most of the sewage during the movement, and the sealing film 77 is used to completely isolate the sewage.

[0034] In some other embodiments, a magnetic sealing ring 10 is installed in one of the magnetic ring grooves. The magnetic sealing ring 10 is made of a soft polymer compound ring filled with magnetic particles inside. Under the adsorption of the outer magnetic ring 9, the magnetic particles inside it move close to the inner wall of the cup body 2, causing the soft polymer compound ring to deform and attach to the inner wall of the cup body 2, thereby isolating the filter core seat 7 from clean water and sewage.

[0035] In some other embodiments, a magnetic sealing ring 10 is installed in at least one of the magnetic ring grooves, two inner magnetic rings 8 are installed in the two magnetic ring grooves, and a reset spring is arranged between the connecting gaps of the inner magnetic rings 8. The magnetic sealing ring 10 is used to isolate the filter element seat 7 and the cup body 2, the inner magnetic ring 8 provides most of the sealing isolation and provides magnetic attraction force, and the outer magnetic ring 9 moves under the joint action and realizes micro displacement during magnetic attraction with the outer magnetic ring 9, which provides power for filter element self-cleaning.

[0036] During long-term use, large particles in sewage can block the filter screen of the combined filter element. The self-cleaning function of the combined filter element 3 is described below. In this embodiment, the combined filter element 3 is installed inside the filter element seat 7, and the combined filter element 3 includes, but is not limited to, a stainless steel filter screen 31, a coarse filtering pp cotton layer, an activated carbon layer, and a microporous filtering fiber layer from bottom to top. The stainless steel filter screen 31 is attached to the cleaning brush plate 80. A semicircular groove is formed on the side of the filter element seat 7 for installing the cleaning brush plate 80. The cleaning brush plate 80 is fixedly connected with the lowermost semicircular magnetic ring 8a. Two semicircular magnetic rings 8a form a circular magnetic ring and are installed in the first magnetic ring groove 7a of the filter element seat 7. The difference between the inner diameter of the first magnetic ring groove 7a and the inner diameter of the semicircular magnetic ring 8a is D3 mm. When the outer magnetic ring 9 and the semicircular magnetic ring 8a are attracted together, the cleaning brush plate 80 will have a micro displacement of D3 mm. The cleaning brush plate 80 includes a brush area 81 and a water permeable area 82. The brush area 81 is composed of the cleaning brush plate body, water permeable holes 811 uniformly distributed on the cleaning brush plate, and bristles 812 around the water permeable holes.

[0037] During use, the outer magnetic ring 9 drives the inner magnetic ring 8 to realize micro displacement, that is, the cleaning brush plate 80 realizes a micro displacement of D3 mm. During movement, the bristles 812 clean the holes of the stainless steel filter screen 31 of the combined filter element 3, which can improve the service life of the combined filter element.

[0038] In order to facilitate replacement of the combined filter element 3, the combined filter element 3 is installed in the internal cavity of the filter element seat 7. The filter element replacement mechanism includes a movable frame 72, a rotating shaft 73, a movable frame clamping groove 74, and a movable frame clamping head 75. The filter element seat 7 is provided with a fixed frame 71 at the top and a rotating shaft 73 at the bottom. The rotating shaft 73 is connected with the movable frame 72. The surface of the movable frame 72 towards the filter element seat 7 is provided with the movable frame clamping head 75. The movable frame clamping groove 74 is arranged at the bottom of the filter element seat 7 and is opposite to the position of the movable frame clamping head 75.

[0039] Further, in order to quickly connect and separate the movable frame clamping head 75 and the movable frame clamping groove 74, in this embodiment, the lower end of the movable frame clamping head 75 is provided with a hemispherical top head 751. The hemispherical top head 751 is connected with the end of the separation piece shaft 753 through threads. The separation piece shaft 753 is provided with a separation piece 752 which can move up and down. The other end of the separation piece shaft 753 and the other end of the movable frame clamping head 75 are fixedly connected through threads.

[0040] The hemispherical head 751 is fixedly connected with the end of the separation piece shaft 753, the separation piece shaft 753 is provided with the separation piece 752 which can move up and down, the other end of the separation piece shaft 753 is fixedly connected with the movable frame clamping head 75, the movable frame clamping groove 74 is provided with the movable sealing plate 743 which can automatically reset, the movable sealing plate 743 is in separable contact with the hemispherical head 751, the vertical hole 744 is arranged above the movable frame clamping groove 74, the side of the vertical hole 744 is provided with the inclined hole 746, the front end of the inclined hole 746 is provided with the telescopic pressing head 745.

[0041] The movable frame clamping groove 74 is arranged on the main body of the filter element seat 7, the lock head holes are arranged on the two sides of the movable frame clamping groove 74, one telescopic lock head 741 is arranged in each lock head hole, the end face of the lock head 741 towards the hemispherical head 751 is inclined, the top end of the movable frame clamping groove 74 is fixedly connected with the movable sealing plate 743, the movable sealing plate 743 is in separable contact with the hemispherical head 751, the movable sealing plate 743 is fixedly connected with the top end of the movable frame clamping groove 74 through the spring, a gas pressure cavity is formed between the movable sealing plate 743 and the movable frame clamping groove 74, the vertical hole 744 is further arranged above the movable frame clamping groove 74, the side of the vertical hole 744 is provided with three inclined downward inclined holes 746, the front end of the inclined hole 746 is provided with the telescopic pressing head 745.

[0042] When the combined filter element 3 is inserted into the filter element seat 7 as a whole, the movable frame 72 needs to be locked to prevent the combined filter element 3 from falling off, at this time, the hemispherical head 751 of the movable frame 72 is pressed into the movable frame clamping groove 74, the front end of the hemispherical head 751 is in contact with the inclined surface of the lock head 741, the lock head 741 is opened, after the lock head 741 is opened, the plane of the hemispherical head 751 and the plane above the lock head 741 are locked and riveted, at this time, the movable frame 72 is locked.

[0043] It should be noted that, since the hemispherical head 751 further presses into the movable frame clamping groove 74 after being locked by extending into the movable frame clamping groove 74, the movable sealing plate 743 moves upward in the process of the hemispherical head 751 being pressed in, the space of the gas pressure cavity between the movable sealing plate 743 and the movable frame clamping groove 74 is compressed, the transmission medium in the vertical hole 744 and the inclined hole 746 presses the pressing head 745 at the front end of the inclined hole 746 outward, thereby making the pressing head 745 contact the outside of the combined filter element 3 and moving the combined filter element 3 downward by a small displacement, so that the lower surface of the combined filter element 3 is in contact with the surface of the cleaning brush plate 80, that is, the bristles 812 of the cleaning brush plate 80 are in contact with the stainless steel filter screen 31 of the combined filter element 3.

[0044] When the combination filter element 3 needs to be replaced, the movable frame 72 needs to be opened, at this time the movable frame 72 is continuously pressed upward, the separation piece shaft 753 is pressed into the lock head 741, since the side of the separation piece shaft 753 is a triangular surface, the upper inclined surface of the separation piece shaft 753 can make the separation piece shaft 753 penetrate into the inclined surface of the lock head 741, at this time the movable sealing plate 743 is under the action of the spring, the lower inclined surface of the separation piece shaft 753 can make the separation piece shaft 753 leave the lock head 741.

[0045] It should be noted that, since the movable frame 72 is continuously pressed upward, the further space of the air pressure cavity between the movable sealing plate 743 and the movable frame clamping groove 74 is compressed; the combination filter element 3 is continuously displaced downward under the action of the top pressing head 745, when the movable frame 72 is opened, the top pressing head 745 is retracted under the action of the spring, the combination filter element 3 is ejected from the filter element seat 7, which is convenient for replacing the filter element.
