Description
Technical Field
[0001] This invention relates to the field of pesticide residue detection technology, specifically to a device for detecting pesticide residues in fruits and vegetables. Background Technology
[0002] As people's living standards improve, their attention to food safety is also increasing. As an indispensable part of daily life, the issue of pesticide residues in fruits and vegetables has attracted much attention. Traditional methods for detecting pesticide residues in fruits and vegetables usually require sending samples to a professional laboratory for testing. This method is not only time-consuming but also costly. Therefore, a rapid method for detecting pesticide residues is currently being used. Specifically, a portion of the fruit or vegetable sample is first cut off with a knife and placed into a covered measuring cup. The measuring cup is then weighed to ensure that the sample weighs 5g. Next, 10ml of buffer solution is added to the measuring cup, the lid is closed, and the cup is shaken. The sample mixes with the buffer solution. The solution is then extracted using a dropper and dripped onto a pesticide residue test strip. The degree of pesticide residue is determined by the color of the reaction on the test strip.
[0003] Existing detection devices are limited in function and cannot integrate chopping, mixing, and draining operations into a single device, resulting in a cumbersome detection process and low work efficiency. When draining the mixed solution, existing technologies often require the use of droppers, which is complex and inconvenient. When processing fruit and vegetable samples, existing detection devices cannot simultaneously perform chopping and mixing, failing to ensure that pesticide residues in the samples are effectively mixed with the buffer solution, thus affecting the accuracy of pesticide residue detection.

[0042] refer to Figure 7 As shown, the unloading component assembly 07 includes an upper guide frame 71, which is connected to a Y-shaped component 72 via a pivot.

One end of the horizontal push rod 73 contacts the bottle body 11, and the other end of the horizontal push rod 73 contacts the Y-shaped component 72. The upper guide frame 71 and the fixed rear housing 21 are fixedly connected. A spring is sleeved on the outside of the horizontal push rod 73, and the spring is connected between the horizontal push rod 73 and the upper guide frame 71. This spring is used to reset the horizontal push rod 73 and the Y-shaped component 72.
[0043] Working principle: When pesticide residue testing is required on fruits and vegetables, first cut off 5 grams of the fruit or vegetable and place it into the bottle body 11. Then, add 10 ml of buffer solution into the bottle body 11. By operating the connecting component group 05, disconnect one side of the fixed rear shell 21 and the moving front shell 23, allowing the moving front shell 23 to rotate and open. Place the inner bottle component group 01 into the fixed rear shell 21, and the bottle body 11 will contact the fixed rear shell 21 through the limiting groove. Then, reset the moving front shell 23, and through the connection of the connecting component group 05, allow the moving front shell 23 and the fixed rear shell 21 to form a wrap around the bottle body 11. The bottle body 11 is fixed in the fixed rear shell 21 and the moving front shell 23 through the limiting groove.
[0044] Holding the fixed handle 22 with the right hand allows the entire device to move. The left hand rotates the top adjustment knob 32, causing the threaded rod 33 to rotate. This rotation, through the threaded connection between the threaded rod 33 and the top housing 31, causes the top adjustment knob 32, threaded rod 33, moving gear 210, smooth rod 28, connecting ring 27, internal gear ring 26, upper movable cover 25, and sealing ring 29 to move downwards together. This allows the upper movable cover 25 to contact the top of the bottle body 11 through the sealing ring 29, and the moving gear 210 to mesh with the internal gear ring 34. The internal gear 110 and... The internal gear ring 26 will also engage at this time. Then, by shaking the external rocker arm 39, the rotation of the external rocker arm 39 drives the internal gear 110 to rotate through the horizontal shaft 38, bevel gear 37, bevel gear 35, internal gear ring 34, moving gear 210, smooth rod 28, connecting ring frame 27, and internal gear ring 26. This causes the central rotating shaft 12 and the blade 13 to rotate in the bottle body 11. When the blade 13 rotates, it will crush the fruit and vegetable samples in the bottle body 11. The rotation will also cause the fruit and vegetable samples and buffer solution to be stirred and mixed, allowing the pesticide residues in the fruit and vegetable samples to be mixed into the buffer solution.
[0045] Move the entire device onto the pesticide residue test strip, positioning the bottom end of the dispensing nozzle 62 on the test strip. Then, by grasping the fixed handle 22 and the control handle 63, pull the control handle 63 towards the fixed handle 22. The spring element 64 in the lower guide frame 610 will retract, causing the control handle 63 to move the vertical guide rod 65, the movable frame 66, the movable liquid inlet tube 67, the movable ring frame 68, and the movable top column 69 towards the bottom of the bottle 14. During this movement (e.g. Figure 7As shown, the spring 16 inside the bottle will move upward and contact the rubber seal 15. As the moving top column 69 continues to move, it will push the rubber seal 15 upward. The spring 16 inside the bottle will store force and contract. Due to the movement of the rubber seal 15, one end of the liquid passage 17 at the bottom of the bottle will no longer be blocked by the rubber seal 15. As a result, the mixed solution inside the bottle body 11 will pass through the filter ring 18, the liquid passage 17 at the bottom of the bottle, the liquid outlet 19 at the bottom of the bottle, the moving ring frame 68, the moving liquid pipe 67 and the liquid outlet 62, and flow out into the pesticide residue test paper below. The pesticide residue test paper can detect the pesticide content in the solution, thereby achieving the detection purpose.
[0046] After a certain amount of solution has been discharged, releasing the control handle 63 will release the stored force of the spring component 64 and the inner spring component 16, allowing the control handle 63 and the rubber seal 15 to return to their original positions. At this point, the solution inside the bottle 11 will no longer be discharged. By controlling the movement of the entire device and by pulling and releasing the control handle 63, the solution can continue to flow precisely and quantitatively onto subsequent test strips. The overall operation steps of moving, discharging, and closing the discharging are easy to control and use, making it convenient to drip the solution onto multiple test strips. The accuracy of pesticide residue detection can be improved by testing with multiple test strips.
[0047] After completing the current fruit and vegetable pesticide residue test, by pinching the two outer strips 53 closer together, the outer spring 55 is compressed and retracted. The locking block 54 disengages from the slot of the moving protrusion 51, thereby releasing the connection between the fixed rear housing 21 and the moving front housing 23. By holding the fixed handle 22 with the right thumb, the Y-shaped part 72 can be directly pressed, causing the Y-shaped part 72 to rotate around the pivot between itself and the upper guide frame 71. When the Y-shaped part 72 rotates, it pushes the horizontal push rod 73 to move. Specifically, the direction of movement is pressing the Y-shaped part 72. The Y-shaped component 72 will rotate clockwise, while the horizontal push rod 73 will be pushed to the left. In turn, one end of the horizontal push rod 73 will push the bottle body 11, allowing the bottle body 11 to disengage from the limiting groove of the fixed shell 21, making it convenient for the operator to remove the inner bottle component group 01. After cleaning the inner bottle component group 01, the next fruit and vegetable sample to be tested and the buffer solution will be put back into the bottle body 11. Then the inner bottle component group 01 will be put into the outer shell component group 02, and the next cycle of mixing, draining and testing can be carried out.
[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
