[0030] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0031] Reference Figure 1 This utility model discloses a high-efficiency dust removal device for thin sheet samples, including a base 1. A gas channel 9 is fixedly connected to the top of the base 1. The gas channel 9 is very narrow, so the flow rate is fast. According to Bernoulli's principle, in fluid flow, the faster the flow rate, the lower the static pressure. The sample at the top of the gas channel 9 is fixed. A connecting plate 2 is fixedly connected to the top of the rear end of the base 1. A motor 10 is fixedly connected to the inner wall of the connecting plate 2. The motor 10 is fixed to the right side of the connecting plate 2. The suction pipe 15 and the delivery pipe 17 are flexible hoses for easy movement.

[0032] Reference Figure 2 - Figure 4 A lead screw 12 is fixedly connected to the output end of motor 10. A connecting frame 5 is provided on the left side of connecting plate 2. An air chamber 6 is fixedly connected inside the connecting frame 5. An ultrasonic generator is located at the bottom of the air chamber 6 (not shown in the attached diagram). This device is at the bottom of the blowing chamber of the air chamber 6 to clean impurities. There are suction chambers on both sides of the air chamber 6 to draw in air and impurities, which are then removed through suction pipe 15. The blowing chamber is located in the middle of the air chamber 6. The shape and size of the blowing chamber can be changed to deliver gas from air pump 16 to clean impurities on the sample. Pressurized air is introduced. A support plate 7 is fixedly connected to the front right side of the connecting plate 2, and an air pump 16 is fixedly connected to the top of the support plate 7. The support plate 7 provides fixed support for the air pump 16. An exhaust pipe 20 is fixedly connected to the right side of the gas channel 9. The air in the gas channel 9 is discharged into the filter box 8 for filtration through the exhaust pipe 20. The filter box 8 is fixedly connected to the right side of the exhaust pipe 20. Impurities are filtered through the filter box 8, and clean gas is delivered. The top of the gas channel 9 has evenly distributed air holes 19. The sample is placed on top of the air holes 19.

[0033] Reference Figure 2 - Figure 4The filter box 8 contains a filter assembly, which includes a fixing plate 26. The fixing plate 26 and bolts 27 limit the movement of the connecting frame 23. The fixing plate 26 is fixedly connected to the outer walls of the left and right sides of the front end of the filter box 8. The inner walls of the upper and lower ends of the filter box 8 are provided with sliding grooves 21. Sliding blocks 22 are slidably connected to the inner walls of the sliding grooves 21. The front end of the sliding blocks 22 has a sealing gasket to prevent air leakage. The connecting frame 23 is fixedly connected between the sliding blocks 22. The filter screen 24 and activated carbon plate 25 inside the connecting frame 23 can be removed and cleaned through the sliding grooves 21 and the sliding blocks 22. For filtering impurities in the air, a filter screen 24 is fixedly connected to the inner left wall of the connecting frame 23, and an activated carbon plate 25 is fixedly connected to the inner right wall of the connecting frame 23. Bolts 27 are threadedly connected between the fixing plates 26. The bolts 27 are rotated into the fixing plates 26 to limit the connection frame 23. A nut pair 13 is threadedly connected to the outer left ring of the lead screw 12. A movable seat 14 is fixedly connected to the outer left wall of the nut pair 13. A guide post 11 is slidably connected through the front end of the movable seat 14 and is fixedly connected to the connecting plate 2. A guide rail 3 is fixedly connected to the middle section of the inner top wall of the connecting plate 2. A sliding block 4 is slidably connected to the outer wall of the guide rail 3. Furthermore, the sliding block 4 is fixedly connected to the movable seat 14. The guide rail 3 has limiters on both sides to limit the movement of the sliding block 4. A connecting frame 5 is fixedly connected to the bottom of the sliding block 4. The motor 10 drives the lead screw 12 to rotate, which in turn moves the nut assembly 13. The nut assembly 13 is fixed to the movable seat 14. The guide post 11 guides and limits the movable seat 14, causing it to move left and right. This moves the sliding block 4 along the outer wall of the guide rail 3, and consequently, the connecting frame 5. The connecting frame 5 is fixed to the air chamber 6, causing the air chamber 6 to move and clean impurities from the sample. (Air pump...) The outlet end of the air chamber 6 is fixedly connected to a delivery pipe 17, which passes through the middle of the air chamber 6 and is fixedly connected. The delivery pipe 17 can be extended and bent. The top of the left and right sides of the air chamber 6 is fixedly connected to a suction pipe 15, which passes through the gas channel 9 and is fixedly connected. The suction pipe 15 can be bent to facilitate the movement of the air chamber 6 and move the suction pipe 15 together. The outlet end of the filter box 8 is fixedly connected to a clean pipe 18, which is fixedly connected to the inlet end of the air pump 16. The filter box 8 filters the air, which is then drawn by the air pump 16 and delivered through the clean pipe 18.

[0034] Working principle: Gas is drawn in by air pump 16 and delivered through clean pipe 18. The clean gas is then delivered to the middle of air chamber 6, blowing out air to clean the sample. Impurities and air are drawn away through suction pipes 15 on both sides of air chamber 6 and then transported through gas channel 9 and vent 19. Gas channel 9 is very narrow, resulting in a high flow rate. According to Bernoulli's principle, in fluid flow, the higher the flow rate, the lower the static pressure. This fixes the sample at the top of gas channel 9. Simultaneously, air enters the filter box 8 and is filtered by filter screen 24 and activated carbon plate 25. Impurities are filtered, and then clean gas is delivered. The motor 10 drives the lead screw 12 to rotate, which in turn drives the nut assembly 13 to move. The nut assembly 13 is fixed to the moving seat 14. The guide post 11 guides and limits the moving seat 14, causing it to move left and right. This causes the sliding block 4 to move on the outer wall of the guide rail 3, which in turn moves the connecting frame 5. The connecting frame 5 is fixed to the gas chamber 6, which in turn moves the gas chamber 6 to clean impurities from the sample. The bolt 27 is then unscrewed, and the filter screen 24 and activated carbon plate 25 inside the connecting frame 23 are removed through the sliding groove 21 and the slider 22 for cleaning.
