[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0027] In the scheme of the present invention, the self-cleaning magnetic movable filter element device is applied to filtering equipment, and these filtering equipment include but are not limited to liquid filtering equipment such as water purification cups, water purification filter bottles, hydraulic oil filters, etc.

[0028] The filtering device must include a self-cleaning magnetic movable filter element device, and in order to install the self-cleaning magnetic movable filter element device into the filtering device, an installation connecting pipe or cavity of the filter element device is provided.

[0029] Taking the application in water purification cup as an example, a self-cleaning magnetic mobile filter device is installed in the water cup to achieve water purification. Figure 1-11As shown, the following describes how the filter element 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; a self-cleaning magnetic mobile filter element device, comprising a filter element seat 7 installed in the cup body 2, the filter element seat 7 is provided with a cavity, a combined filter element 3 is installed in the cavity, and a filter element replacement mechanism is provided at the bottom of the filter element seat 7; a magnetic ring groove is provided on the side of the filter element seat 7, and an inner magnetic ring 8 is installed in the magnetic ring groove in a longitudinal arrangement and can be displaced left and right in the magnetic ring groove; and the bottom inner magnetic ring 8 is cleaned by a brush plate 80; a semicircular groove hole 76 is provided on the side of the filter element seat 7 for installing and connecting the cleaning brush plate 80 of the bottom inner magnetic ring 8; the bottom of the combined filter element 3 and the cleaning brush plate 80 are fitted and connected.

[0030] like Figure 1 As 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. The 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, and the semicircular magnetic rings are symmetrically clamped in the magnetic ring groove; the outer wall of the filter element seat 7 is initially 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 fitted with the inner wall of the cup body 2 under the adsorption action of the outer magnetic ring 9; the outer edge of the upper wall of the filter element seat 7 is also provided with a sealing soft film 73. When the inner magnetic ring 8 is installed, three groups of inner magnetic rings 8 are staggered and superimposed in the magnetic ring groove.

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

[0032] In order to ensure that the outer wall and the inner wall of the cup body 2 are sealed during the up and down movement of the filter element seat 7 to prevent sewage from entering the water purification chamber, the present embodiment is designed with three sets of magnetic ring grooves, and the three sets of magnetic ring grooves correspond to the inner magnetic rings 8 respectively.

[0033] The inner magnetic ring 8 is made of a semicircular solid magnet with an edible silica gel surface and an inner coating. 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 very small amount of water will leak out from the gap area of ​​the inner magnetic ring 8. When the inner magnetic ring 8 is installed, the gap areas of the magnetic rings are staggered 60 degrees and superimposed and installed 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 73 is provided at the circumferential edge of the filter element seat 7. The sealing film 73 is used to completely isolate a small part of the sewage leaking from the gap area. It should be noted that the three groups of inner magnetic rings 8 are staggered and overlapped. One function is to increase the magnetic force to facilitate the filter element seat 7 to be adsorbed by the outer magnetic ring 9 and then realize the up and down movement; the other function is to isolate most of the sewage during the movement, and then cooperate with the sealing film 73 to achieve complete isolation of 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 with magnetic particle material filled inside. The magnetic sealing ring 10 can also be made of a soft polymer compound ring with magnetic particle material filled inside. Under the adsorption action of the outer magnetic ring 9, the magnetic particles inside it approach the inner wall of the cup body 2, so that the soft polymer compound ring is slightly deformed and fits against the inner wall of the cup body 2, thereby allowing the filter element seat 7 to isolate 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, an inner magnetic ring 8 is installed in the two magnetic ring grooves, and a reset spring is arranged between the connection gaps of the inner magnetic ring 8. The magnetic sealing ring 10 is used to isolate the filter element seat 7 and the cup body 2, and the inner magnetic ring 8 provides most of the sealing isolation and provides magnetic adsorption force and moves under the joint action of the outer magnetic ring 9, and realizes micro displacement during the magnetic adsorption process with the outer magnetic ring 9 to provide power for self-cleaning of the filter element.

[0036] During long-term use, large particles in sewage will clog the filter screen of the combined filter element. The following describes the self-cleaning function of the combined filter element 3. In this embodiment, the combined filter element 3 is installed inside the filter element seat 7. The combined filter element 3 includes, but is not limited to, a stainless steel filter screen 31, a coarse filtration PP cotton layer 32, an activated carbon layer 33, and a microporous filtration fiber layer 34 from the bottom to the top; the stainless steel filter screen 31 is attached to the cleaning brush plate 80; a semicircular through hole is opened on the side of the filter element seat 7 for installing the cleaning brush plate 80, and the cleaning brush plate 80 and the top are connected. The lower semicircular magnetic ring 8a is fixedly connected, and the 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 D3mm, that is, when the outer magnetic ring 9 and the semicircular magnetic ring 8a are adsorbed together, the cleaning brush plate 80 will have a micro-displacement of D3mm; the cleaning brush plate 80 includes a bristle area 81 and a water permeable area 82, and the bristle area 81 is composed of the cleaning brush plate body and the water permeable holes 811 evenly distributed on the cleaning brush plate, and the bristles 812 around the water permeable holes.

[0037] When in use, the outer magnetic ring 9 drives the inner magnetic ring 8 to achieve micro-displacement, that is, the cleaning brush plate 80 achieves a micro-displacement of D3mm. During the movement, the bristles 812 clean the holes of the stainless steel filter screen 31 of the combined filter element 3, which can increase the service life of the combined filter element.

[0038] In order to facilitate the 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 slot 74, and a movable frame clamp 75. The filter element seat 7 is provided with a filter element seat 71 with a fixed frame at the top and a filter element seat 73 with a rotating shaft at the bottom. The rotating shaft 73 is connected to the movable frame 72. A movable frame clamp 75 is provided on the surface of the movable frame 72 facing the filter element seat 71. The movable frame slot 74 is provided at the bottom of the filter element seat 71, opposite to the movable frame clamp 75.

[0039] A hemispherical top head 751 is provided at the bottom end of the frame clamp 75, and the hemispherical top head 751 is fixedly connected to the end of the separation sheet shaft 753, and a separation sheet 752 that can move up and down is installed on the separation sheet shaft 753; the other end of the separation sheet shaft 753 is fixedly connected to the other end of the movable frame clamp 75; an automatically reset movable sealing plate 743 is provided in the movable frame slot 74, and the movable sealing plate 743 is detachably contacted and connected with the hemispherical top head 751 to form an air pressure chamber; a vertical hole 744 is provided above the movable frame slot 74, and an inclined hole 746 is provided on the side of the vertical hole 744, and a retractable top pressure head 745 is provided at the front end of the inclined hole 746.

[0040] In order to further enable the movable frame clamp 75 and the movable frame clamping slot 74 to be quickly connected and separated; in this embodiment, the lower end of the movable frame clamp 75 is provided with a hemispherical head 751, and the hemispherical head 751 is connected to the end of the separator shaft 753 through a thread, and the separator shaft 753 is provided with a separator 752 that can move up and down; the other end of the separator shaft 753 is fixedly connected to the other end of the movable frame clamp 75 through a thread;

[0041] The movable frame slot 74 is provided on the main body of the filter element seat 7, and lock holes are provided on both sides of the movable frame slot 74. A retractable lock 741 is installed in each lock hole. The end surface of the lock 741 facing the hemispherical top head 751 is an inclined surface. The top end of the movable frame slot 74 is fixedly connected with a movable sealing plate 743. The movable sealing plate 743 and the hemispherical top head 751 are detachably contacted and connected. The movable sealing plate 743 is fixedly connected to the top end of the movable frame slot 74 through a spring, and an air pressure chamber is formed between the movable sealing plate 743 and the movable frame slot 74; a vertical hole 744 is also provided above the movable frame slot 74, and three oblique holes 746 obliquely downward are provided on the side of the vertical hole 744, and a retractable top pressure head 745 is provided at the front end of the oblique hole 746;

[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 slot 74, and the front end of the hemispherical head 751 contacts the inclined surface of the lock head 741, and the lock head 741 is pushed open. After being pushed open, the plane of the hemispherical head 751 and the plane above the lock head 741 are locked and riveted, and the movable frame 72 is locked;

[0043] It should be noted that, as the hemispherical top head 751 is inserted into the movable frame slot 74 and locked and further pressed in, the movable sealing plate 743 moves upward during the pressing process of the hemispherical top head 751, and the space of the air pressure chamber between the movable sealing plate 743 and the movable frame slot 74 is compressed. The transmission medium in the vertical hole 744 and the inclined hole 746 presses the top pressure head 745 at the front end of the inclined hole 746 outward, thereby making the top pressure head 745 contact with the outer side of the combined filter element 3 and slightly displacing the combined filter element 3 downward, so that the lower surface of the combined filter element 3 and the surface of the cleaning brush plate 80 fit together, that is, the bristles 812 of the cleaning brush plate 80 and the stainless steel filter mesh 31 of the combined filter element 3 fit together.

[0044] When the combined filter element 3 needs to be replaced, the movable frame 72 needs to be opened. At this time, the movable frame 72 is continued to be pressed upward to press the separation plate shaft 753 into the lock 741. Since the side surface of the separation plate shaft 753 is a triangular surface, the upper inclined surface of the separation plate shaft 753 can allow the separation plate shaft 753 to penetrate the inclined surface of the lock 741. At this time, under the action of the spring of the movable sealing plate 743, the lower inclined surface of the separation plate shaft 753 can allow the separation plate shaft 753 to leave the lock 741.

[0045] It should be noted that, as the movable frame 72 continues to press upward, the further space of the air pressure chamber between the movable sealing plate 743 and the movable frame slot 74 is compressed; the combined filter element 3 continues to move downward under the action of the top pressure head 745. When the movable frame 72 is opened, the top pressure head 745 retracts under the action of the spring, and the combined filter element 3 is pushed out of the filter element seat 7, making it convenient to replace the filter element.
