[0004] However, the device still has some shortcomings: the device can crush fruit and vegetable samples to extract liquid, but the extracted juice is in a static state after mixing with the reaction liquid, and the staff needs to manually shake the reaction tube to promote good mixing of the juice and the reaction liquid. However, different staff members have different shaking strength and duration, which makes it easy for the test results to differ and affects the accuracy. Summary of the invention

When the electric rotating rod rotates, it drives the connecting plate to rotate, and the connecting plate drives the ring to rotate along the inner wall of the separation barrel. The connecting plate rotates and disturbs the falling sample. At the same time, the electric rotating rod drives the ring to rotate, and intercepts and blocks the falling sample through the separation filter plate. When the ring rotates, it drives the crushing component to rotate. When the crushing component rotates, it rotates and cuts the test sample that falls into the separation filter plate. At the same time, when the crushing component rotates and cuts the sample, the ring drives the rolling roller to move synchronously. When the rolling roller revolves, its outer wall contacts the bottom of the inner wall of the separation filter plate to generate friction The grinding roller generates friction and starts to rotate. When the grinding roller rotates, it revolves and grinds the sample cut and crushed by the crushing component to produce juice. The juice falls into the grinding barrel, and the reaction liquid is added to the grinding barrel through the adding component. Then the control body prompts the detection component to draw the mixed liquid of the sample juice and the reaction liquid into itself through the delivery pipe for pesticide residue detection. When the electric rotating rod rotates, it is restricted by the inner wall of the reciprocating spiral groove on its outer wall and the built-in block of the sliding ring. When the electric rotating rod rotates, it prompts the sliding ring to slide back and forth upward and reset, and the sliding ring drives the hollow cone plate to move synchronously, and the hollow cone plate drives the limit ring to slide synchronously along the inner wall of the grinding barrel.

[0007] According to the above technical solution, the outer wall of the rolling roller contacts the bottom of the inner wall of the separation filter plate, a number of the rolling rollers and a number of crushing components are adjacently distributed on the outer wall of the sleeve ring, a filter hole is opened on the outer wall of the hollow cone plate, the hollow cone plate is located inside the grinding barrel, the outer wall of the limit ring is slidably connected to the inner wall of the grinding barrel, and an anti-turbidity device for removing dirt or soil on the surface of the test sample is arranged above the circular ring.

[0008] According to the above technical scheme, the anti-turbidity device includes a vertical rod, a conical sieve plate, a resistance block, an intercepting mesh plate, a fixed rod and an arc block. The bottom of the vertical rod is fixedly installed on the top of the connecting plate, the bottom edge of the conical sieve plate is fixedly installed on the top of the vertical rod, the bottom of the resistance block is fixedly installed on the top of the connecting plate, the resistance block is located outside the vertical rod, the outer wall of the intercepting mesh plate is slidably installed on the inner wall of the funnel, the top of the fixed rod is fixedly installed on the left inclined surface of the outer wall of the intercepting mesh plate, the top of the arc block is fixedly installed on the bottom of the fixed rod, and the connecting plate drives the vertical rod to rotate when it revolves, and the vertical rod rotates When it rotates, it drives the conical sieve plate to rotate. The conical sieve plate rotates and guides the samples falling into the funnel through its own inclined surface, so that the samples fall evenly into the funnel. At the same time, the conical sieve plate drives the resistance block to rotate. During the revolution of the resistance block, it contacts the arc surface of the outer wall of the arc block and generates a resistance force. The arc block pushes the fixed rod upward through the upward resistance force, and the fixed rod drives the intercepting mesh plate to slide upward along the inner wall of the funnel and the outer wall of the conical sieve plate. At this time, the intercepting mesh plate opens the cover to the conical sieve plate, so that the samples can fall orderly relying on the circular indirection between the conical sieve plate and the intercepting mesh plate.

[0009] According to the above technical solution, the conical sieve plate is located inside the funnel, the bottom of the intercepting mesh plate contacts the outer wall of the conical sieve plate, the arc surface of the arc block is located on the motion trajectory of the arc surface of the resistance block, and the inner wall of the intercepting mesh plate is provided with a flipping device for continuously disturbing the test sample in the funnel.

[0010] According to the above technical solution, the anti-turbidity device also includes a spring piece and a knocking column. The spring piece is fixedly installed between the inner wall of the funnel and the top of the outer wall of the interception mesh plate. The knocking column is fixedly installed on the concave surface of the spring piece at one end away from the inner wall of the funnel. The knocking column contacts the inner wall of the funnel at one end away from the concave surface of the spring piece. When the interception mesh plate slides upward, it resists the spring piece and deforms. When the spring piece deforms, it drives the knocking column to move away from the inner wall of the funnel. When the interception mesh plate drives the spring piece to suddenly reset, the spring piece drives the knocking column to suddenly knock on the inner wall of the funnel to generate vibration during the recovery process. The interception mesh plate and the conical screen plate are caused to vibrate synchronously through the transmission of force.

[0011] The top of the L-shaped rod is hinged at the inner wall of the funnel, the top inclined surface of the U-groove plate is hinged at the bottom of the L-shaped rod, a sliding groove is opened inside the U-groove plate, and the dispersion plate is hinged at the outer wall of the U-groove plate at one end close to the outer wall of the L-shaped rod, and the bottom of the L-shaped rod contacts the inner wall of the interception mesh plate, and the reset plate is fixedly installed between the inclined surface of the outer wall of the dispersion plate and the outer wall of the U-groove plate. When the interception mesh plate drives its own sample to move upward, the L-shaped rod limits the U-groove plate to force the U-groove plate to remain stationary. At the same time, the inner wall of the interception mesh plate contacts the bottom of the dispersion plate to cause friction. At this time, the hinge shaft of the dispersion plate starts to rotate and causes the dispersion plate to swing upward in an arc with the hinge shaft as the axis. The dispersion plate squeezes the reset plate and deforms synchronously. Then the dispersion plate is reset by the elastic force of the reset plate. This reciprocating process causes the dispersion plate to swing back and forth upward and reset.

When the intercepting mesh plate moves upward, the push block is driven to move synchronously, and the hollow plate slides upward along the inner groove of the U-groove plate, the push block contacts the outer wall of the hollow plate and pushes the hollow plate to slide upward along the bottom of the inner wall of the U-groove plate, and the hollow plate drives the rotary wheel to move synchronously and rub along the inner wall of the U-groove plate, prompting the rotary wheel to generate a rotating force and start to rotate, the rotary wheel drives the round rod to rotate, the round rod drives the fan plate to rotate, and the fan plate drives the curved plate to rotate when it rotates, and then the hollow plate slides and resets under the influence of its own gravity and the inclined surface of the U-groove plate.

[0013] According to the above technical solution, the internal sliding groove of the U-groove plate is located on the movement track of the push block, the outer wall of the hollow plate is located on the movement track of the push block, and the outer wall of the rotating wheel is in contact with the inner wall of the U-groove plate.

[0014] The present invention provides a rapid detection device for pesticide residues in food. It has the following beneficial effects:

[0015] (1) The present invention prevents the sample from being gathered in the center of the separation filter plate and affecting the overall crushing and crushing process by cooperating with a circular ring, a connecting plate, an electric rotating rod, a separation filter plate, a sleeve ring, a crushing assembly, a crushing roller, a sliding ring, a hollow cone plate and a limiting ring, and realizes the solid-liquid separation of the sample to improve the purity of the detection liquid. At the same time, the juice crushed out after the cell wall of the sample is crushed is more representative than the pesticide residue detection result of ordinary cutting and soaking, which is beneficial to the improvement of detection accuracy; and the hollow cone plate drives the limiting ring to fully stir the detection juice and the reaction liquid in the grinding barrel, so as to replace the traditional manual shaking and vibration with stirring to promote good mixing of the juice and the reaction liquid, and avoid the difference in shaking intensity and duration of different staff affecting the mixing effect. The hollow cone plate relies on its own outer wall filter holes to intercept the fine debris in the falling detection juice and does not prevent the juice from falling into the grinding barrel. (2) The present invention provides an anti-turbidity device, and cooperates with the connecting plate, vertical rod, conical sieve plate, abutment block, interception mesh plate, fixed rod, arc block, spring sheet and knocking column to prevent the sample from falling into the funnel and being shielded by the conical sieve plate and the interception mesh plate. In addition, when the conical sieve plate rotates and swings the sample, dirt or mud on the surface of the sample falls into the conical sieve plate and the interception mesh plate, thereby preventing the mixed liquid being tested from becoming too turbid due to interference from mud or dirt, thereby affecting the detection process and results of pesticide residues. In addition, the swinging force generated by the rotation of the conical sieve plate effectively improves the removal effect of the interception mesh plate and the conical sieve plate on the dirt on the sample surface, while preventing the dirt from adhering to the outer wall surface of the interception mesh plate or the conical sieve plate, thereby preventing the next batch of test samples from being contaminated. (3) The present invention sets a flipping device, and cooperates with an intercepting mesh plate, an L-shaped rod, a U-groove plate, a dispersion plate, a reset plate, a push block, a hollow plate, a rotating wheel, a round rod, a fan plate and an arc plate. The sample is swung and guided by the reciprocating swing of the dispersion plate, so that the sample is continuously moved toward the conical sieve plate under the beating of the dispersion plate. The two promote the sample to be continuously flipped during the beating and swinging process, thereby effectively avoiding mutual adhesion, preventing the dirt on the adhered part from being difficult to separate from the sample surface and reducing the overall cleanliness of the sample; at the same time, relying on the fanning of the fanning plate and the arc surface guidance of the arc plate, the dispersion effect of the sample is further improved without damaging the sample surface. At the same time, the flipping frequency of the sample inside the funnel is increased within the same time, effectively improving the removal effect of the dirt with strong stickiness on the sample surface.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-Figure 8One embodiment of the present invention is: a rapid detection device for pesticide residues in food, comprising a control body 1, a separation barrel 2 is arranged on the left side of the top of the control body 1, a funnel 21 is arranged on the top of the separation barrel 2, an adding component 22 is arranged on the left side of the outer wall of the separation barrel 2, a detection component 23 is arranged on the right side of the separation barrel 2, the left side of the detection component 23 is connected to the inside of the separation barrel 2 through a conveying pipe 24, and the conveying pipe 24 is built with a filter screen, a grinding barrel 3 is arranged at the bottom of the inner wall of the separation barrel 2, and the inside of the grinding barrel 3 is connected to the adding component 22 and the conveying pipe 24. The pipe 24 is connected, a circular ring 6 is slidably installed on the upper inner wall of the separation barrel 2, a plurality of connecting plates 7 are fixedly installed on the inner wall of the circular ring 6, an electric rotating rod 8 is fixedly installed on one end of the connecting plates 7 near the center of the separation barrel 2, a reciprocating spiral groove is provided at the lower outer wall of the electric rotating rod 8, a separation filter plate 9 is fixedly installed on the inner wall of the separation barrel 2, the separation filter plate 9 is located below the circular ring 6, a sleeve 10 is fixedly installed on the outer wall of the electric rotating rod 8, a plurality of crushing components 11 are fixedly installed on the outer wall of the sleeve 10, and the bottom of the crushing component 11 contacts the bottom of the inner wall of the separation filter plate 9 , a plurality of rolling rollers 12 are rotatably installed on the outer wall of the sleeve ring 10, a sliding ring 13 is slidably installed through the outer wall of the reciprocating spiral groove of the electric rotating rod 8, a hollow cone plate 14 is fixedly installed on the outer wall of the sliding ring 13, and a limit ring 15 is fixedly installed on the bottom of the hollow cone plate 14. Through the above cooperation, the sample is prevented from being gathered in the center of the separation filter plate 9 to affect the overall crushing and crushing process, and the solid-liquid separation of the sample is realized to improve the purity of the detection liquid. At the same time, the juice crushed after the cell wall of the sample is crushed is more representative than the pesticide residue detection result of ordinary cutting and soaking, which is beneficial to the improvement of detection accuracy; through the above cooperation, the hollow cone plate 14 drives the limit ring 15 to fully stir the detection juice and the reaction liquid inside the grinding barrel 3, and the stirring replaces the traditional manual shaking vibration to promote the good mixing of the juice and the reaction liquid, so as to avoid the different shaking and oscillation strength and duration of different staff members affecting the mixing effect, and the hollow cone plate 14 relies on its own outer wall filter hole to intercept the fine debris in the falling detection juice and does not prevent the juice from falling into the grinding barrel 3.

[0027] The outer wall of the rolling roller 12 contacts the bottom of the inner wall of the separation filter plate 9, and a plurality of rolling rollers 12 and a plurality of crushing components 11 are adjacently distributed on the outer wall of the sleeve ring 10. The outer wall of the hollow cone plate 14 is provided with filter holes, and the hollow cone plate 14 is located inside the grinding barrel 3. The outer wall of the limiting ring 15 is slidably connected to the inner wall of the grinding barrel 3, and an anti-turbidity device 4 for removing dirt or soil on the surface of the test sample is arranged above the circular ring 6.

[0028] When in use, the test sample enters the separation barrel 2 through the funnel 21, and the electric rotating rod 8 is started. When the electric rotating rod 8 rotates, it drives the connecting plate 7 to rotate. The connecting plate 7 drives the ring 6 to rotate along the inner wall of the separation barrel 2. The connecting plate 7 rotates and disturbs the falling sample. At the same time, the electric rotating rod 8 drives the ring 10 to rotate, and the falling sample is intercepted and blocked by the separation filter plate 9. When the ring 10 rotates, it drives the crushing component 11 to rotate. When the crushing component 11 rotates, it rotates and cuts the test sample that falls into the separation filter plate 9. At the same time, the crushing component 11 When the sample is rotated and cut, the sleeve ring 10 drives the rolling roller 12 to move synchronously. When the rolling roller 12 revolves, its outer wall contacts the bottom of the inner wall of the separation filter plate 9 to generate friction and start to rotate. When the rolling roller 12 rotates, it revolves and rolls the sample cut and crushed by the crushing component 11 to produce juice. The juice falls into the grinding barrel 3, and the reaction liquid is added to the grinding barrel 3 through the adding component 22. Then the control body 1 prompts the detection component 23 to draw the mixed liquid of the sample juice and the reaction liquid into itself through the conveying pipe 24 for pesticide residue detection. The above coordination prevents the sample from being concentrated inside the separation filter plate 9 and affects the overall crushing and rolling process, and realizes the solid-liquid separation of the sample to improve the purity of the detection liquid. At the same time, the juice crushed after the cell wall of the sample is crushed is more representative than the pesticide residue detection result of ordinary cutting and soaking, which is beneficial to the improvement of detection accuracy; when the electric rotating rod 8 rotates, it is limited by the inner wall of the reciprocating spiral groove on its outer wall and the built-in block of the sliding ring 13. When the electric rotating rod 8 rotates, the sliding ring 13 is able to slide back and forth upward and reset, and the sliding ring 13 drives the hollow cone plate 14 to move simultaneously. The hollow cone plate 14 drives the limiting ring 15 to slide synchronously along the inner wall of the grinding barrel 3. The above cooperation enables the hollow cone plate 14 to drive the limiting ring 15 to fully stir the test juice and the reaction liquid inside the grinding barrel 3, so as to replace the traditional manual shaking vibration with stirring to promote a good mixing of the juice and the reaction liquid, thereby avoiding the difference in shaking intensity and duration of different staff affecting the mixing effect. The hollow cone plate 14 relies on the filter holes on its outer wall to intercept the fine debris in the falling test juice without preventing the juice from falling into the grinding barrel 3.

[0029] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-turbidity device 4;

[0030] The anti-turbidity device 4 includes a vertical rod 41, a conical sieve plate 42, a resistance block 43, an intercepting mesh plate 44, a fixed rod 45 and an arc block 46. The bottom of the vertical rod 41 is fixedly mounted on the top of the connecting plate 7, the bottom edge of the conical sieve plate 42 is fixedly mounted on the top of the vertical rod 41, the bottom of the resistance block 43 is fixedly mounted on the top of the connecting plate 7, the resistance block 43 is located outside the vertical rod 41, the outer wall of the intercepting mesh plate 44 is slidably mounted on the inner wall of the funnel 21, the top of the fixed rod 45 is fixedly mounted on the left inclined surface of the outer wall of the intercepting mesh plate 44, and the top of the arc block 46 is fixedly mounted on the bottom of the fixed rod 45. Through the above cooperation, the sample is blocked by the conical sieve plate 42 and the intercepting mesh plate 44 when it falls into the funnel 21, and the dirt or soil on the surface of the sample falls into the conical sieve plate 42 and the intercepting mesh plate 44 during the process of the conical sieve plate 42 rotating and swinging the sample, so as to prevent the detected mixed liquid from being too turbid due to the interference of soil or dirt, thereby affecting the detection process and detection results of pesticide residues.

[0031] The conical sieve plate 42 is located inside the funnel 21 , the bottom of the intercepting mesh plate 44 contacts the outer wall of the conical sieve plate 42 , the arc surface of the arc block 46 is located on the arc surface motion trajectory of the resistance block 43 , and the inner wall of the intercepting mesh plate 44 is provided with a flipping device 5 for continuously disturbing the test sample in the funnel 21 .

[0032] The anti-turbidity device 4 also includes a spring piece 47 and a knocking column 48. The spring piece 47 is fixedly installed between the inner wall of the funnel 21 and the top of the outer wall of the interception mesh plate 44. The knocking column 48 is fixedly installed on the concave surface of the spring piece 47 at one end away from the inner wall of the funnel 21. The knocking column 48 is in contact with the inner wall of the funnel 21 at one end away from the concave surface of the spring piece 47. The above coordination combined with the swinging force of the rotation of the conical sieve plate 42 effectively improves the removal effect of the interception mesh plate 44 and the conical sieve plate 42 on the dirt on the sample surface, and at the same time prevents dirt from adhering to the outer wall surface of the interception mesh plate 44 or the conical sieve plate 42, thereby preventing the next batch of test samples from being contaminated.

[0033] When in use, the connecting plate 7 drives the vertical rod 41 to rotate when it revolves, and the vertical rod 41 drives the conical sieve plate 42 to rotate when it rotates. The conical sieve plate 42 rotates and guides the sample falling into the funnel 21 through its own inclined surface, so that the sample falls evenly into the funnel 21. At the same time, the conical sieve plate 42 drives the resistance block 43 to rotate. During the revolution of the resistance block 43, it contacts the arc surface of the outer wall of the arc block 46 and generates a resistance force. The arc block 46 pushes the fixed rod 45 upward through the upward resistance force. The fixed rod 45 pushes the interception mesh plate 44 to slide upward along the inner wall of the funnel 21 and the outer wall of the conical sieve plate 42. At this time, the interception mesh plate 44 opens the shielding of the conical sieve plate 42, so that the sample can fall in an orderly manner by relying on the circular indirection between the conical sieve plate 42 and the interception mesh plate 44. Through the above cooperation, the sample is blocked by the conical sieve plate 42 and the interception mesh plate 44 when it falls into the funnel 21, and the conical sieve plate 42 rotates to throw During the sample moving process, dirt or soil on the sample surface falls into the conical sieve plate 42 and the intercepting mesh plate 44, preventing the detected mixed liquid from being too turbid due to the interference of dirt or soil, thereby affecting the detection process and detection results of pesticide residues; when the intercepting mesh plate 44 slides upward, it contacts the spring piece 47 and deforms, and when the spring piece 47 deforms, it drives the knocking column 48 to move away from the inner wall of the funnel 21. When the intercepting mesh plate 44 drives the spring piece 47 to suddenly reset, the spring piece 47 drives the knocking column 48 to suddenly knock the inner wall of the funnel 21 during the recovery process to generate vibration, and the intercepting mesh plate 44 and the conical sieve plate 42 are caused to vibrate synchronously through the transmission of force. The above coordination combined with the swinging force of the rotation of the conical sieve plate 42 effectively improves the removal effect of the intercepting mesh plate 44 and the conical sieve plate 42 on the dirt on the sample surface, and at the same time prevents dirt from adhering to the outer wall surface of the intercepting mesh plate 44 or the conical sieve plate 42, so as to prevent the next batch of test samples from being contaminated.

[0034] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes a flipping device 5;

[0035] The flipping device 5 includes an L-shaped rod 51, a U-groove plate 52, a dispersion plate 53 and a reset plate 54. The top of the L-shaped rod 51 is hinged at the inner wall of the funnel 21, and the top inclined surface of the U-groove plate 52 is hinged at the bottom of the L-shaped rod 51. A sliding groove is provided inside the U-groove plate 52. The dispersion plate 53 is hinged at the outer wall of the U-groove plate 52 at one end close to the outer wall of the L-shaped rod 51. The bottom of the L-shaped rod 51 contacts the inner wall of the intercepting mesh plate 44. The reset plate 54 is fixedly installed between the outer wall inclined surface of the dispersion plate 53 and the outer wall of the U-groove plate 52. Through the above cooperation, the sample is swung and guided by the reciprocating swing of the dispersion plate 53, so that the sample is continuously moved toward the conical sieve plate 42 under the beating of the dispersion plate 53. As a result, the two promote the sample to be continuously flipped during the beating and swinging process, thereby effectively avoiding mutual adhesion, preventing the dirt in the bonding part from being difficult to separate from the sample surface and reducing the overall cleanliness of the sample.

[0036] The turning device 5 also includes a push block 55, a hollow plate 56, a rotating wheel 57, a round rod 58, a plurality of fanning plates 59 and a plurality of arc plates 510. The bottom of the push block 55 is fixedly mounted on the inner wall of the intercepting mesh plate 44, the bottom of the hollow plate 56 is slidably mounted on the bottom of the inner wall of the U-groove plate 52, the bottom of the rotating wheel 57 is rotatably mounted on the top of the hollow plate 56, the bottom of the round rod 58 is fixedly mounted on the top center of the rotating wheel 57, a plurality of fanning plates 59 are equidistant and fixedly mounted on the outer wall surface of the round rod 58, and a plurality of arc plates 510 are equidistant and fixedly mounted on the inner wall of the fanning plate 59. Through the above cooperation, relying on the fanning of the fanning plate 59 and the arc surface guiding of the arc plate 510, the dispersion effect of the sample is further improved without damaging the sample epidermis. At the same time, the turning frequency of the sample inside the funnel 21 is increased within the same length of time, and the removal effect of the highly sticky dirt on the sample surface is effectively improved.

[0037] The inner slide groove of the U-groove plate 52 is located on the movement track of the push block 55 , the outer wall of the hollow plate 56 is located on the movement track of the push block 55 , and the outer wall of the rotating wheel 57 contacts the inner wall of the U-groove plate 52 .

[0038] When in use, when the intercepting mesh plate 44 drives its own sample to move upward, the L-shaped rod 51 limits the U-groove plate 52 to make the U-groove plate 52 remain still, and at the same time, the inner wall of the intercepting mesh plate 44 contacts the bottom of the dispersion plate 53 to cause friction. At this time, the hinge axis of the dispersion plate 53 begins to rotate and causes the dispersion plate 53 to swing upward in an arc with the hinge axis as the axis. The dispersion plate 53 squeezes the reset plate 54 and deforms synchronously. Then, the dispersion plate 53 is reset by the elastic force of the reset plate 54, and the reciprocating process causes the dispersion plate 53 to be able to swing back and forth upward and reset. Through the above cooperation, the reciprocating swing of the dispersion plate 53 is used to swing and guide the sample, so that the sample is continuously moved toward the conical sieve plate 42 under the impact of the dispersion plate 53. As a result, the two promote the sample to be continuously flipped during the flapping and swinging process, thereby effectively avoiding mutual adhesion, preventing the dirt on the bonding part from being difficult to separate from the sample surface and reducing the overall cleanliness of the sample; the intercepting mesh plate 44 When moving upward, the push block 55 is driven to move synchronously, and the hollow plate 56 slides upward along the internal slide groove of the U-groove plate 52. The push block 55 will contact the outer wall of the hollow plate 56 and push the hollow plate 56 to slide upward along the bottom of the inner wall of the U-groove plate 52. The hollow plate 56 drives the rotating wheel 57 to move synchronously and rub along the inner wall of the U-groove plate 52, so that the rotating wheel 57 generates a rotational force and starts to rotate. The rotating wheel 57 drives the round rod 58 to rotate, and the round rod 58 drives the fan plate 59 to rotate. When the fan plate 59 rotates, it drives the arc plate 510 to rotate. Then, the hollow plate 56 slides and resets under the influence of its own gravity and the inclined surface of the U-groove plate 52. Through the above cooperation, relying on the fanning of the fan plate 59 and the arc surface guidance of the arc plate 510, the dispersion effect of the sample is further improved without damaging the sample epidermis. At the same time, the flipping frequency of the sample inside the funnel 21 is increased within the same length of time, which effectively improves the removal effect of the dirt with strong stickiness on the sample surface.
