Description

Technical Field

[0001] The invention relates to the technical field of pesticide residue detection, and in particular to a device for detecting pesticide residues in fruits and vegetables. Background Art

[0002] As people's living standards improve, they pay more and more attention to food safety. As an indispensable food in daily life, fruits and vegetables have attracted much attention for their pesticide residues. The traditional method of detecting pesticide residues in fruits and vegetables usually requires sending fruit and vegetable samples to a professional laboratory for testing. This method is not only time-consuming but also costly. Therefore, a rapid method of detecting pesticide residues is currently used, which is as follows: first use a knife to cut off some fruit and vegetable samples into a measuring cup with a lid, then weigh the measuring cup to ensure that the mass of the fruit and vegetable samples inside is 5g, then add 10ml of buffer solution to the measuring cup, cover the measuring cup lid, and shake the measuring cup. The fruit and vegetable samples inside will be mixed with the buffer solution. Subsequently, a dropper is used to extract the mixed solution and drip it onto the pesticide residue detection test paper. The degree of pesticide residue is judged by the color of the reaction on the test paper.

[0003] The existing detection device has a single function and cannot integrate the chopping, stirring and draining operations into one device, resulting in a cumbersome detection process and low work efficiency; when draining the mixed solution, the existing technology often requires the use of a dropper for pipetting, which is complicated and inconvenient to use; when processing fruit and vegetable samples, the existing detection device is difficult to achieve simultaneous chopping and stirring, and cannot ensure that the pesticide residues in the fruit and vegetable samples are effectively mixed with the buffer solution, affecting the accuracy of pesticide residue detection.

[0043] Working principle: When it is necessary to test the pesticide residues of fruits and vegetables, first cut off 5 grams of fruits and vegetables and put them into the bottle body 11, and then put 10 ml of buffer into the bottle body 11. The connection between the fixed rear shell 21 and the moving front shell 23 is released by operating the connecting component group 05, and the moving front shell 23 is rotated to open, and the inner bottle component group 01 is put into the fixed rear shell 21, and the bottle body 11 will contact the fixed rear shell 21 through the limiting groove, and then the moving front shell 23 is reset, and through the connection of the connecting component group 05, the moving front shell 23 and the fixed rear shell 21 form a package around the bottle body 11, and the bottle body 11 is fixed in the fixed rear shell 21 and the moving front shell 23 through the limiting groove.

[0044] The right hand holds the fixed handle 22 to drive the entire device to move. The left hand turns the top adjusting button 32 to drive the threaded rod 33 to rotate. The threaded rod 33 rotates through the threaded connection with the top shell 31 to drive the top adjusting button 32, the threaded rod 33, the moving gear 210, the smooth rod 28, the connecting ring frame 27, the inner gear ring 26, the upper movable cover 25 and the sealing ring 29 to move downward together, so that the upper movable cover 25 can contact the top of the bottle body 11 through the sealing ring 29, and the moving gear 210 will mesh with the inner gear ring 24, and the gear 110 and the inner gear ring 26 will mesh with each other. The inner gear ring member 26 will also mesh at this time, and then rotate by shaking the outer rocker member 39. The outer rocker member 39 rotates through the horizontal shaft member 38, the bevel gear member 2 37, the bevel gear member 1 35, the inner gear ring member 2 34, the movable gear member 210, the light rod member 28, the connecting ring frame 27, and the inner gear ring member 26 to drive the gear member 110 in the bottle to rotate, thereby allowing the transfer shaft member 12 and the blade member 13 to rotate in the bottle body member 11. The blade member 13 will crush the fruit and vegetable samples in the bottle body member 11 when rotating, and drive the fruit and vegetable samples and the buffer solution to be stirred and mixed through the rotation, so that the pesticide residues in the fruit and vegetable samples can be mixed into the buffer solution.

[0045] Move the whole device onto the pesticide residue test paper, let the bottom end of the liquid discharge nozzle 62 be located on the test paper, then hold the fixed handle 22 and the control handle 63, let the fingers pull the control handle 63 to move in the direction of the fixed handle 22, the spring member 2 64 in the lower guide frame 610 will accumulate force and contract, the control handle 63 will drive the vertical guide rod 65, the moving frame 66, the moving liquid pipe 67, the moving coil frame 68 and the moving top column 69 to move in the direction of the bottle bottom member 14, and during the movement (such as Figure 7As shown), it will move upward and contact the rubber seal 15. As the movable top column 69 continues to move, the movable top column 69 will push the rubber seal 15 upward, and the spring member 16 in the bottle will accumulate force and contract. Due to the movement of the rubber seal 15, the opening at one end of the bottle bottom liquid passage 17 will no longer be blocked by the rubber seal 15, and then the mixed solution in the bottle body 11 will pass through the filter ring 18, the bottle bottom liquid passage 17, the bottle bottom discharge port 19, the movable coil frame 68, the movable liquid pipe 67 and the discharge nozzle 62, and flow out to the pesticide residue detection test paper below. The pesticide residue detection test paper can detect the pesticide content in the solution, thereby achieving the detection purpose.

[0046] After a certain amount of solution is discharged, the control handle 63 is released, and the spring member 64 and the spring member 16 in the bottle release the stored force to return the control handle 63 and the rubber seal 15 to their original positions. At this time, the solution inside the bottle body 11 will no longer be discharged, and the solution can continue to flow out accurately and quantitatively onto subsequent test strips by controlling the movement of the entire device and by pulling and releasing the control handle 63. The overall operation steps of moving, discharging and closing the drainage are easy to control and use, which makes it convenient to drip the solution into multiple test strips, and improve the accuracy of pesticide residue detection through the detection of multiple test strips.

[0047] After the current fruit and vegetable pesticide residue detection is completed, the two outer strips 53 are squeezed to move closer to each other, so that the outer spring member 55 accumulates force and contracts, and the block member 54 is separated from the contact with the slot of the movable protrusion member 51, thereby releasing the connection between the fixed rear housing 21 and the movable front housing 23. The Y-shaped member 72 can be directly pressed by the thumb of the right hand holding the fixed handle 22, so that the Y-shaped member 72 rotates around the rotating shaft between the upper guide frame 71 and the Y-shaped member 72. When the Y-shaped member 72 rotates, it pushes the horizontal push rod member 73 to move. The specific moving direction is to press the Y-shaped member 72. The Y-shaped member 72 will rotate clockwise, and the horizontal push rod 73 will be pushed to move to the left, and then one end of the horizontal push rod 73 will push the bottle body member 11, so that the bottle body member 11 can be disengaged from the limiting groove of the fixed rear shell 21, so that the operator can take out the inner bottle component group 01 conveniently. After the inner bottle component group 01 is cleaned, the next fruit and vegetable sample and buffer solution to be tested are put into the bottle body member 11 again, and then the inner bottle component group 01 is 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 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 the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
