However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Example 1: As Figures 1-11 As shown, this utility model provides a multi-layer composite filter medium suction filtration device, including: a base plate 1, a suction bottle 2 disposed on the top of the base plate 1, a first support shaft 3 fixedly connected to the top of the suction bottle 2, a first funnel 4 fixedly connected to the top of the first support shaft 3, three evenly arranged first rotating shafts 5 rotatably connected to the outer surface of the first support shaft 3, and second funnels 6 fixedly connected to the outer surfaces of the three first rotating shafts 5, a sealing assembly 8 disposed on the top of the base plate 1, the sealing assembly 8 including a slider 801, a second support shaft 802 fixedly connected to the top of the slider 801, a second rotating shaft 803 fixedly connected to the top end of the second support shaft 802, two first moving blocks 804 rotatably connected to the outer surface of the second rotating shaft 803, a fixed block 805 fixedly connected to one side of the outer surface of each of the two first moving blocks 804, a spring 806 disposed between the outer surfaces of the two fixed blocks 805, the two ends of the spring 806 being fixedly connected to the outer surfaces of the two fixed blocks 805 respectively, and a second moving block fixedly connected to the other side of the outer surface of each of the two first moving blocks 804. 807, multiple third moving blocks 808 are fixedly connected to the inner walls of the two second moving blocks 807, and sealing strips 809 are fixedly connected to the inner walls of the multiple third moving blocks 808. The top of the suction flask 2 is in contact with the bottom of one of the second funnels 6. A filter barrel 9 is fixedly connected to the top of the first funnel 4. A cover plate 10 is fixedly connected to the top of the filter barrel 9. A fixed shaft 11 is fixedly connected between the opposite outer surfaces of the cover plate 10. A third rotating shaft 12 is movably fitted onto the outer surface of the fixed shaft 11. The outer surface of the third rotating shaft 12... A fourth moving block 13 is fixedly connected to the surface. A groove 7 is provided on the top of the bottom plate 1 near one edge. The inner wall of the groove 7 is slidably connected to the outer surface of the slider 801. A motor 14 is provided on the top of the cover plate 10. An output shaft 15 is fixedly connected to the output end of the motor 14. One end of the output shaft 15 moves through the inner wall of the cover plate 10 and extends to the outside. A first rotating block 16 is fixedly sleeved on the outer surface of the output shaft 15 near one end. A plurality of evenly arranged second rotating blocks 17 are fixedly connected to the outer surface of the first rotating block 16.

[0034] The effect achieved by the whole embodiment 1 is that when the multi-layer composite filter medium filtration device is in normal use and needs to filter the solution, the worker can rotate the second funnel 6, which will drive the inside of the first rotating shaft 5 to rotate along the outer surface of the first supporting shaft 3. The worker puts the filter medium needed into the second funnel 6, and after the putting is completed, the worker rotates the second funnel 6 again, which will drive the inside of the first rotating shaft 5 to rotate around the outer surface of the first supporting shaft 3 until the second funnel 6 stops rotating when it is directly above the filtration bottle 2. Then the worker moves the second supporting shaft 802 in parallel, which will simultaneously drive the sliding block 801 and the second rotating shaft 803 to move in parallel. The outer surface of the sliding block 801 will slide along the inside of the sliding groove 7, and the second rotating shaft 803 will drive the first moving block 804, the fixed block 805, the spring 806 and the second moving block 807 to move in parallel. The second moving block 807 will drive the third moving block 808 to move, and the third moving block 808 will drive the sealing strip 809 to move. When the surface of the second moving block 807 approaches the outer surface of the second funnel 6, the worker needs to move the fixed block 805, moves the two fixed blocks 805 towards each other, which will squeeze the spring 806 between the outer surfaces of the two fixed blocks 805, and the fixed block 805 will drive the inside of the first moving block 804 to rotate around the outer surface of the second rotating shaft 803. The two first moving blocks 804 will drive the two second moving blocks 807 to move towards each other, and the two second moving blocks 807 will drive the multiple third moving blocks 808 fixed on their outer surfaces to move towards each other. The third moving block 808 will drive the sealing strip 809 to move. When the outer surfaces of the two second moving blocks 807 can pass through the outer surface of the second funnel 6, the second supporting shaft 802 is moved again until the second funnel 6 is located at the center of the two second moving blocks 807. The worker no longer presses the fixed block 805, and the elastic force of the spring 806 will drive the two fixed blocks 805 to move away from each other. The fixed block 805 will drive the inside of the first moving block 804 to rotate around the outer surface of the second rotating shaft 803, and the two first moving blocks 804 will drive the two second moving blocks 807 to move towards each other. The second moving block 807 will drive the third moving block 808 to move, and the third moving block 808 will drive the sealing strip 809 to move. The surface of the sealing strip 809 will fit the gap of the second funnel 6, thereby ensuring the sealing effect of the multi-layer composite filter medium filtration device. Then the worker moves the fourth moving block 13 again, which will drive the inside of the third rotating shaft 12 to rotate around the outer surface of the fixed shaft 11. When the fourth moving block 13 no longer fits the top of the filter barrel 9, the worker pours the solution needed to be filtered into the filter barrel 9. After the pouring is completed, the fourth moving block 13 is moved again, which will drive the inside of the third rotating shaft 12 to rotate around the outer surface of the fixed shaft 11 until the outer surface of the fourth moving block 13 fits the top of the filter barrel 9.At this point, the solution, mixed with impurities, is flowing downwards through the first funnel 4 onto the filter medium in the second funnel 6. Then, the operator starts the motor 14 and vacuum pump 21. The motor 14 drives the output shaft 15 to rotate, which in turn drives the first rotating block 16 to rotate. The first rotating block 16 then drives the second rotating block 17 to rotate. The rotation of multiple second rotating blocks 17 helps to evenly distribute the solid particles in the solution. The vacuum pump 21, through the safety bottle 19, creates an initial negative pressure in the filtration flask 2. This negative pressure accelerates the flow rate of the solution through the filter medium in the first funnel 4 and the second funnel 6, allowing the solid particles in the solution to settle and be intercepted more quickly. By setting up multiple second funnels 6, various filter media can be placed. The sealing assembly 8 seals the gaps in the second funnels 6, thus solving the problem that a single filter medium can only intercept particles of a certain size and cannot remove all impurities, leading to a decrease in filtration quality.

[0035] Example 2: As Figures 1-11 As shown, the outer surface of the filtration bottle 2 is fixedly connected to a first pipe 18, a safety bottle 19 is set at the top of the base plate 1 near the center, the outer surface of the safety bottle 19 is fixedly connected to one end of the first pipe 18, the outer surface of the safety bottle 19 is fixedly connected to a second pipe 20, and a vacuum pump 21 is set at the top of the base plate 1 near the other edge, the output end of the vacuum pump 21 is fixedly connected to one end of the second pipe 20.

[0036] The effect achieved by the entire embodiment 2 is that after the filtration is completed, the vacuum pump 21 is turned off. After the vacuum pump 21 is turned off, the negative pressure environment in the filtration bottle 2 and the safety bottle 19 gradually becomes the same as the external environmental pressure. Because the liquid in the filtration bottle 2 will be back-drawn into the first pipe 18 due to the change in air pressure, and then flows into the safety bottle 19 through the inside of the first pipe 18. The safety bottle 19 prevents the liquid from being drawn into the vacuum pump 21 and damaging the vacuum pump 21, thereby ensuring the stable operation of the multi-layer composite filter medium filtration device.

[0037] Working principle: when the multi-layer composite filter medium filter device is in normal use, when filtering the solution, the worker puts the filter medium needed into the second funnel 6 by rotating the second funnel 6, and then rotates the second funnel 6 again until the second funnel 6 is located directly above the filter bottle 2, the worker moves the second support shaft 802 until the surface of the second moving block 807 approaches the outer surface of the second funnel 6, then the worker moves the fixed block 805 again, the two fixed blocks 805 will drive the rotation of the first moving block 804 while extruding the spring 806, the first moving block 804 will drive the second moving block 807 to move, when the distance between the two second moving blocks 807 is appropriate, the second support shaft 802 is moved again until the second funnel 6 is located at the center of the two second moving blocks 807, then the worker no longer presses the fixed block 805, the elastic force of the spring 806 will drive the two fixed blocks 805 to move away from each other, the fixed block 805 will drive the first moving block 804 to rotate, the first moving block 804 will drive the second moving block 807 to move towards each other, the second moving block 807 will drive the sealing strip 809 to move, the surface of the sealing strip 809 will fit the gap of the second funnel 6, then the worker pours the solution needed to be filtered into the filter barrel 9, the worker starts the motor 14 and the vacuum pump 21, the motor 14 will drive the second rotating block 17 to rotate, the vacuum pump 21 will make the environment in the filter bottle 2 in the initial negative pressure state through the safety bottle 19, so as to accelerate the flow rate of the solution through the filter medium in the first funnel 4 and the second funnel 6, when the filtering is completed, the vacuum pump 21 is closed, after the vacuum pump 21 is closed, the negative pressure environment in the filter bottle 2 and the safety bottle 19 slowly communicates with the external environment pressure, because the liquid in the filter bottle 2 will be sucked into the first pipeline 18 under the change of air pressure, and then flows into the safety bottle 19 through the inside of the first pipeline 18, through the safety bottle 19, the liquid is prevented from being sucked into the vacuum pump 21, by arranging the multi-layer second funnel 6, a plurality of filter media can be placed, and by using the sealing assembly 8 to seal the gap of the second funnel 6, the problem that a single filter medium can only intercept particles of a certain size and cannot remove all impurities, thereby reducing the filtering quality, is solved.

[0038] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application still falls within the protection scope of the technical scheme of the present application.
