[0039] The filter device 4 includes a water-proof chamber 41 and a separation chamber 42. A driving member 43 is provided between the water-proof chamber 41 and the separation chamber 42 to drive the separation chamber 42 to rotate so that the liquid in the separation chamber 42 enters the water-proof chamber 41. A rubber tube 5 is fixedly connected to the bottom of the water-proof chamber 41, and the rubber tube 5 is sleeved in the extrusion tube 23.

[0040] An opening and closing member 6 is provided between the stirring tube 21 and the filtering tube 22 so that when the filtering tube 22 rotates, the liquid in the stirring tube 21 flows toward the filtering tube 22 .

[0041] Specifically, the object to be detected is placed on one side of the bottom of the stirring tube 21. Before placing the stirring rod 31, the main storage bin 32 is rotated to separate the main storage bin 32 from the auxiliary storage bin 33, and the main storage bin 32 and the auxiliary storage bin 33 are in end-to-end contact. Then the stirring rod 31 is placed in the stirring bin, so that the object to be detected is placed on the outside of the fan-shaped area after the main storage bin 32 and the auxiliary storage bin 33 are in end-to-end contact. A sufficient amount of buffer solution is poured into the stirring tube 21, and then the stirring rod 31 is rotated forward so that the auxiliary storage bin 33 drives the main storage bin 32 to rotate, thereby stirring the stirring tube 21.

[0042] After the buffer solution and the object to be detected are fully stirred, the stirring rod 31 is rotated in the opposite direction, so that the auxiliary storage chamber 33 rotates toward the main storage chamber 32, and the auxiliary storage chamber 33 drives the object to be detected in the stirring tube 21 to move toward the main storage chamber 32, and the buffer solution is filtered through the auxiliary filter 35. When the auxiliary storage chamber 33 overlaps with the main storage chamber 32, the object to be detected is stored in the main filter 34 and the auxiliary filter 35, and then the opening and closing member 6 is opened to make the buffer solution in the stirring tube 21 flow into the filter tube 22, so that the buffer solution enters the separation chamber 42, and at this time, the separation chamber 4 is driven by the driving member 43. 2 rotates at a high speed, so that the liquid in the separation chamber 42 flows into the water-proof chamber 41, and the liquid flows into the rubber tube 5, and the liquid in the rubber tube 5 flows out by squeezing the squeezing tube 23, and then the liquid is collected into a corresponding test tube, and a specific fluorescent dye or absorbent is added to the liquid, which will react with the target molecule in a specific chemical reaction and produce a specific absorption or fluorescence phenomenon at a specific wavelength, which can be measured by the spectrometer 1 and compared with the standard control to determine the presence and concentration of the target molecule in the sample, thereby detecting the residual pesticide of the species to be detected;

[0043] After the buffer solution in the stirring tube 21 is fully integrated with the object to be detected, the object to be detected is stored between the main filter 34 and the auxiliary filter 35 through the overlap between the main storage chamber 32 and the auxiliary storage chamber 33, and the setting of the main filter 34 and the auxiliary filter 35, thereby forming a primary filtration. Through the setting of the separation chamber 42, the buffer solution is subjected to a secondary filtration, thereby filtering the contaminants in the buffer solution, thereby avoiding the problem that impurities in the reagent will produce baseline fluctuations and dissolution peaks in the spectrum during the detection process of the spectrometer 1, thereby affecting the accuracy of the analysis results.

[0046] A connecting block 11 is fixedly connected to one side of the auxiliary storage bin 33, and the connecting block 11 is fixedly connected to the outer periphery of the stirring rod 31. The other side of the auxiliary storage bin 33 is in contact with the inner wall of the stirring tube 21.

When the auxiliary storage bin 33 rotates in the reverse direction, one side of the auxiliary storage bin 33 overlaps with one side of the main storage bin 32.

After the buffer solution is added, the main rectangular frame 321 is rotated by the rotating plate 8 to control the main rectangular frame 321 and the secondary rectangular frame 331. The stirring rod 31 is controlled to rotate forward, thereby driving the secondary rectangular frame 331 to rotate forward, and then the secondary rectangular frame 331 drives the main rectangular frame 321 to rotate forward, so that the object to be detected and the buffer solution are fully stirred, and the residues and other impurities generated after stirring are isolated by the main filter 34 and the secondary filter 35 in the fan-shaped area with a larger angle formed by the main rectangular frame 321 and the secondary rectangular frame 331, so that the reaction liquid in the fan-shaped area with a smaller angle formed by the main rectangular frame 321 and the secondary rectangular frame 331 is in a state without impurities with excessively large particles;

[0049] When the reaction between the object to be detected and the buffer solution is completed, the stirring rod 31 is rotated in the opposite direction, so that the stirring rod 31 drives the sub-rectangular frame 331 to rotate, and the sub-rectangular frame 331 and the sub-filter 35 inside drive the object to be detected and the residue in the reaction liquid toward the main filter 34. When the main rectangular frame 321 and the sub-rectangular frame 331 overlap, the object to be detected is stored in the main filter 34 and the sub-filter 35.

[0050] Embodiment three:

[0051] The difference from the above-mentioned embodiment 2 is that, see Figure 5-Figure 8 For the main storage bin 32, the stirring assembly 0 includes an elastic plate 01, a main rectangular frame 321 is rotatably connected to a reciprocating screw 02 on one side near the inner wall of the stirring tube 21 through a bearing, one end of the reciprocating screw 02 extends to the top of the main rectangular frame 321, a moving block 03 is provided on one side of the main rectangular frame 321, the moving block 03 is assembled on the reciprocating screw 02 through a thread, the elastic plate 01 is provided on one side of the moving block 03, the top of the main rectangular frame 321 is rotatably connected to a first gear 04 through a bearing, and the first gear 04 is fixed to one end of the reciprocating screw 02 The inner wall of the stirring tube 21 is fixedly connected with an annular tooth plate 05, the first gear 04 is meshed with the annular tooth plate 05, a rectangular groove 06 is provided on one side of the moving block 03, a guide groove 07 is provided on the inner wall of the main rectangular frame 321 close to the stirring rod 31, sliding plates 08 are slidably connected on both sides of the guide groove 07, guide rods are fixedly connected between the two sliding plates 08 and in the rectangular groove 06, both ends of the elastic plate 01 are sleeved on the guide rods, and a spring 09 is fixedly connected to the side of the elastic plate 01 away from the main filter screen 34, and the spring 09 is sleeved on the guide rod;

[0052] Specifically, when the stirring rod 31 rotates, the secondary rectangular frame 331 drives the main rectangular frame 321 to rotate, and through the meshing connection between the first gear 04 and the annular gear plate 05, the first gear 04 is driven to rotate, thereby driving the reciprocating screw 02 to rotate, and through the threaded connection between the reciprocating screw 02 and the moving block 03, the moving block 03 is driven to move up and down, thereby driving the elastic plate 01 to move up and down. Since the main filter screen 34 has a certain elasticity, during the rotation of the main rectangular frame 321, when the main filter screen 34 contacts the object to be detected, the object to be detected will impact the main filter screen 34, and cause the main filter screen 34 and the object to be detected to undergo elastic deformation backwards. At this time, through the up and down movement of the moving block 03 and the setting of the spring 09 on one side of the elastic plate 01, the main filter screen 34 and the object to be detected are driven to move in the direction of the main rectangular frame 321, thereby rolling, impacting and stirring the object to be detected, and making the object to be detected fully contact with the buffer solution.

[0053] Embodiment 4:

[0054] The difference from the above-mentioned embodiment 3 is that, see Figure 9-10 For the above-mentioned opening and closing member 6, the opening and closing member 6 includes a plurality of elastic plugs 61, a baffle 62 is fixedly connected to the bottom of the inner cavity of the stirring tube 21, a plurality of through holes 63 are opened on the baffle 62, the top of the filter tube 22 is rotatably connected to the stirring tube 21 through a roller bearing, a sealing ring 64 is fixedly connected to the top of the outer periphery of the filter tube 22, the sealing ring 64 is sleeved on the outside of the stirring tube 21, an inclined ring plate 65 is fixedly connected to the inner cavity of the filter tube 22, and a plurality of elastic plugs 61 are fixedly installed on the inclined ring plate 65, and the elastic plugs 61 are consistent with the through holes 63.

[0055] Specifically, when the reaction liquid in the stirring tube 21 is fully stirred, the filter tube 22 is rotated to cause the elastic plug 61 on the inclined ring plate 65 to undergo elastic deformation and detach from the through hole 63 , so that the reaction liquid in the stirring tube 21 flows into the filter tube 22 through the through hole 63 .

[0056] Embodiment five:

[0057] The difference from the above-mentioned fourth embodiment is that, see Figure 9-10 For the above-mentioned filter tube 22, the water-proof chamber 41 includes a transverse ring plate 411 and a longitudinal ring plate 412. The transverse ring plate 411 is arranged at the bottom of the inclined ring plate 65 and is fixedly connected to the inclined ring plate 65. The longitudinal ring plate 412 is fixedly installed at the inner ring of the bottom of the transverse ring plate 411. The separation chamber 42 includes an inclined filter bucket 421 and a movable ring plate 422.

A tooth groove 433 is provided on the outer periphery of the movable ring plate 422. The second gear 431 is meshed and connected with the movable ring plate 422 through the tooth groove 433.

[0059] Specifically, the reaction liquid in the stirring tube 21 flows into the inclined filter bucket 421, and at the same time, the second gear 431 is driven to rotate by the motor 432. The movable ring plate 422 is driven to rotate through the meshing connection between the second gear 431 and the tooth groove 433 on the outer periphery of the movable ring plate 422, thereby driving the inclined filter bucket 421 to rotate. The centrifugal force generated by the inclined filter bucket 421 filters the impurities in the reaction liquid, so that the filtered reaction liquid enters the gap between the longitudinal ring plate 412 and the inclined filter bucket 421, and flows into the rubber tube 5.

[0060] Embodiment six:

[0061] See also Figure 1-Figure 10 , this embodiment discloses a detection method, the specific steps are:

Before placing the stirring rod 31, rotate the main storage bin 32 to separate the main storage bin 32 from the auxiliary storage bin 33, and make the main storage bin 32 and the auxiliary storage bin 33 touch each other end to end. Then place the stirring rod 31 into the stirring bin, so that the object to be detected is placed on the outside of the fan-shaped area after the main storage bin 32 and the auxiliary storage bin 33 touch each other end to end, and pour a sufficient amount of buffer solution into the stirring tube 21. Then rotate the stirring rod 31 forward so that the auxiliary storage bin 33 drives the main storage bin 32 to rotate, thereby stirring the stirring tube 21. When the buffer solution and the object to be detected are fully stirred, rotate the stirring rod 31 in the opposite direction so that the auxiliary storage bin 33 rotates toward the main storage bin 32. The auxiliary storage bin 33 drives the object to be detected in the stirring tube 21 to move toward the main storage bin 32, and the buffer solution is filtered through the auxiliary filter 35. When the auxiliary storage bin 33 overlaps with the main storage bin 32, the object to be detected is stored in the main filter 34 and the auxiliary filter 35, and then the opening and closing piece 6 is opened to allow the buffer solution in the stirring tube 21 to flow into the filter tube 22, and the buffer solution enters the separation bin 42. At this time, the separation bin 42 is driven by the driving piece 43 to rotate at a high speed, so that the liquid in the separation bin 42 flows into the water-proof bin 41, and the liquid flows into the rubber tube 5. By squeezing the squeezing tube 23, the liquid in the rubber tube 5 flows out, and then the collected liquid is placed in the spectrometer 1 for detection.
