Description

Technical Field

[0001] This utility model relates to the field of pesticide detection device technology, and in particular to a gel-based pesticide detection imprint particle adsorption device. Background Technology

[0002] Gel-based imprinted particles play an important role in pesticide detection. By immersing the imprinted hydrogel in the test solution and combining it with a portable Raman spectrometer and a pesticide residue detection model, pesticide residues in fruits and vegetables can be detected rapidly and at low cost. In the detection process, the plant is first crushed and the juice is collected. The juice is then poured into a container, where the imprinted particles adsorb the pesticide components in the juice, facilitating subsequent analysis. After extracting the eluent, the pesticide content can be determined.

[0003] Existing gel-based pesticide detection imprint particle adsorption devices require the imprint particles to be poured out after adsorption of the juice, once saturated. Since a single juice sample can be used multiple times, after the first round of adsorption, the saturated imprint particles can be poured out, and then the imprint particles to be adsorbed can be poured into a container. This process requires multiple steps, significantly reducing the convenience of the adsorption operation. Therefore, this application proposes a gel-based pesticide detection imprint particle adsorption device that is easier to operate. Utility Model Content

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, this utility model proposes a gel-based pesticide detection imprint particle adsorption device, including a storage tube 1. A sealing cap 3 is fitted onto the top opening of the storage tube 1 to seal the opening. When the imprint particles adsorb pesticide components from plant juice, the sealing cap 3 seals the opening of the storage tube 1 to prevent juice leakage. A particle storage rack 6 is fixedly installed at the bottom of the sealing cap 3. The particle storage rack 6 is used to store the imprint particles. After the imprint particles are stored in sections on the particle storage rack 6, they are inserted into the storage tube 1 to prevent a large number of imprint particles from piling up and to improve the adsorption effect. When needed... When replacing the imprinted particles, remove the particle storage rack 6 from the liquid storage tube 1, leaving the plant juice inside the liquid storage tube 1. After replacing the imprinted particles, insert the particle storage rack 6 back into the liquid storage tube 1 for subsequent adsorption operations. When it is necessary to discharge the plant juice, rotate the valve rod 41 mounted on the drain pipe 4, which in turn drives the ball valve inside the drain pipe 4 to rotate. Once the drain pipe 4 is opened, the plant juice can be discharged from the drain pipe 4. During the adsorption operation, there is no need to pour the plant juice out of the opening of the liquid storage tube 1 to replace the imprinted particles, making the operation convenient.

[0031] like Figures 2-4As shown, in order to store a large number of imprinted particles in separate sections, a particle storage rack 6 is composed of multiple circular storage boxes 61 and connecting rods 62. Connecting rods 62 are fixedly installed between adjacent circular storage boxes 61. The topmost circular storage box 61 is fixedly connected to the sealing cover 3 via the connecting rods 62, ensuring that the sealing cover 3 and the particle storage rack 6 are integrated. The particle storage rack 6 can be easily removed from the liquid storage tube 1 when the sealing cover 3 is opened, facilitating operation. A large number of imprinted particles are placed in the multiple circular storage boxes 61. When the circular storage boxes 61 are soaked in the plant juice in the liquid storage tube 1, it ensures that the imprinted particles can absorb the pesticide components in the juice. Separate storage prevents a large number of imprinted particles from piling up together, reducing the area covered by the particles and effectively improving their pesticide absorption effect.

[0032] Furthermore, in order to allow the plant sap to enter the multiple circular storage boxes 61, a large number of perforations 611 are drilled at the bottom of the circular storage boxes 61 to ensure that the sap can pass through the perforations 611 and enter the interior of the circular storage boxes 61; the inner diameter of the perforations 611 is smaller than the maximum diameter of the imprint particles to prevent the imprint particles from falling from the perforations 611 into the lower circular storage boxes 61.

[0033] Secondly, when the liquid storage tube 1 is shaken, in order to ensure that the imprint particles can be stably stored in the corresponding circular storage boxes 61, an annular groove 612 is cut on the outer wall of the circular storage box 61. An annular rubber ring 613 is embedded and fitted in the annular groove 612. When the particle storage rack 6 is inserted into the liquid storage tube 1, the outer wall of the annular rubber ring 613 is in close contact with the inner wall of the liquid storage tube 1, avoiding gaps between the outer wall of the circular storage box 61 and the inner wall of the liquid storage tube 1. Therefore, it can prevent the imprint particles from rolling from the gap into the adjacent circular storage box 61, effectively improving the stability of the partitioned storage of imprint particles.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, in order to improve the sealing effect of the sealing cap 3, a rubber stopper 32 is fixedly installed at the bottom of the sealing cap 3. When the sealing cap 3 is snapped into place at the top of the liquid storage tube 1, the rubber stopper 32 is inserted into the inside of the liquid storage tube 1 and comes into close contact with its inner wall, effectively preventing the juice from leaking out from the opening of the liquid storage tube 1 and improving the sealing effect.

[0035] Secondly, in order to improve the firmness of the connection between the sealing cap 3 and the liquid storage tube 1, a locking block 31 is fixedly installed at the bottom of the sealing cap 3, and a locking groove 12 is cut at the top of the liquid storage tube 1. After the sealing cap 3 is fixed at the top of the liquid storage tube 1, the locking block 31 is inserted into the matching locking groove 12, and then a bolt is turned in from the outside of the liquid storage tube 1 to lock the locking block 31, which effectively improves the firmness of the connection between the sealing cap 3 and the liquid storage tube 1. When the liquid storage tube 1 is shaken, the sealing cap 3 can be prevented from falling off the liquid storage tube 1.

[0036] like Figure 1 and Figure 2 As shown, in order to prevent the liquid storage tube 1 from falling off the hand when shaking the liquid storage tube 1, two collars 11 are fixedly installed on the outer wall of the liquid storage tube 1. Two anti-fall sleeves 2 are fixedly installed on the two collars 11. When the worker puts his palm into the area between the anti-fall sleeve 2 and the liquid storage tube 1 and holds the liquid storage tube 1, the anti-fall sleeve 2 covers the back of the hand. When shaking the liquid storage tube 1, the anti-fall sleeve 2 can reduce the risk of the liquid storage tube 1 falling off the palm.

[0037] like Figure 1 As shown, in order to facilitate the placement of the liquid storage tube 1 on the operating table, several support rods 51 are fixedly installed at the bottom of the liquid storage tube 1. The bottom ends of the several support rods 51 are all fixedly installed with a base 5. When the liquid storage tube 1 needs to be placed on the operating table, the base 5 provides stable support to the bottom of the liquid storage tube 1, effectively improving the stability of the liquid storage tube 1 after placement.

[0038] In this embodiment, plant juice is first poured into the storage tube 1, and then a large number of imprinted particles are stored in multiple circular storage boxes 61 in sections. This sectioned storage prevents a large number of particles from piling up together, reducing the area covered and improving the adsorption effect when the particles absorb pesticide components from the juice. Next, the particle storage rack 6 is inserted into the storage tube 1, allowing the juice to pass through the drain hole 611 into the circular storage boxes 61, ensuring that all imprinted particles stored in each circular storage box 61 are soaked in the juice. The operator holds the liquid storage tube 1 and shakes it to accelerate the adsorption of pesticide components in the juice by the imprinted particles. After the first round of adsorption is completed and new imprinted particles need to be replaced, the sealing cover 3 is opened and the particle storage rack 6 is removed from the liquid storage tube 1. At this time, the imprinted particles that have reached adsorption saturation are kept in the circular storage box 61, and the plant juice remains in the liquid storage tube 1. After the particle storage rack 6 is removed, the imprinted particles can be replaced without having to pour out the plant juice and the imprinted particles that have reached adsorption saturation together, which effectively improves the convenience of the adsorption operation.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
