[0002] Plasticizer is a toxic plastic softener that can increase the ductility, elasticity and softness of plastic products. Since many foods are processed, heated, packaged and served, plasticizers in plastic utensils dissolve into the food. In order to ensure the safe use of plasticizers, plasticizer detection devices are needed.

[0003] When testing plasticizers, it is necessary to first put the plastic powder into a reagent bottle containing chemical reagents, and then put the reagent bottle into a constant temperature box, and heat and shake the reagent bottle at a constant temperature. The shaking method used in the prior art is to shake the constant temperature box left and right, so that the chemical reagent in the reagent bottle is shaken and constantly in contact with the heating liquid in the constant temperature box, thereby active constant temperature heating. However, the heating liquid in the constant temperature box has uncertainty when shaking. Reagent bottles placed in different areas of the constant temperature box have different contact effects with the shaking heating liquid, resulting in different heating effects obtained by the reagent bottles. Therefore, a new plasticizer detection device is needed. Utility Model Content

[0023] Please refer to the attached Figure 1-2 A plasticizer detection device includes a thermostat 1, a sealing cover 2 is hinged on the upper surface of the thermostat 1, a plurality of legs 8 for supporting the thermostat 1 are connected and fixed at the bottom of the thermostat 1, a handle 3 for conveniently opening the sealing cover 2 is connected and fixed on the upper surface of the sealing cover 2, a servo motor 10 is installed at the bottom of the thermostat 1, an output end of the servo motor 10 is connected and fixed to a rotating rod 11, the rotating rod 11 passes through the bottom of the thermostat 1 and extends into the thermostat 1, a sealing ring 9 is connected and fixed to the portion of the thermostat 1 in contact with the rotating rod 11, and the sealing ring 9 is in rotational contact with the rotating rod 11.

[0024] The rotating rod 11 is connected to a fixed circular plate 4 at one end in the constant temperature box 1, and a plurality of first circular holes arranged in an annular manner for placing reagent bottles 5 are provided on the upper surface of the circular plate 4. Second circular holes are provided on the side of the first circular hole close to the rotating rod 11 and on the side of the first circular hole away from the rotating rod 11. A fixed bearing 12 is connected in the second circular hole, and a stirring rod 6 is connected and fixed in the bearing 12. A plurality of arc plates 7 are connected and fixed to the annular surface of the stirring rod 6, and the arc plates 7 close to the rotating rod 11 rotate in opposite directions to the arc plates 7 away from the rotating rod 11.

[0025] By connecting and fixing a stirring structure composed of a bearing 12, a stirring rod 6 and an arc plate 7 in the second circular hole, when the servo motor 10 drives the circular plate 4 to rotate reciprocally to oscillate the reagent bottle 5, the stirring structure is used to stir the heated liquid in the constant temperature box 1 instead of shaking it, so that the heated liquid in the constant temperature box 1 is heated by contact with the reagent bottle 5 while reducing the shaking amplitude of the water flow, thereby avoiding different heating effects on the reagent bottles 5 in different areas.

[0026] The stirring structure close to the rotating rod 11 rotates in the opposite direction to the stirring structure far from the rotating rod 11, so that when the reagent bottle 5 rotates counterclockwise and clockwise, there is a stirring structure around the reagent bottle 5 to stir the heated liquid around the reagent bottle 5, so that the heating is more uniform.

[0027] A plurality of circular grooves arranged transversely are provided in the first circular hole, and a supporting rod 15 is inserted into the circular groove. One end of the supporting rod 15 in the circular groove is connected to and fixed with an elastic member 13, and the elastic member 13 is a spring.

[0028] By opening a plurality of circular grooves in the first circular hole, installing a supporting structure consisting of a supporting rod 15, an elastic member 13 and a supporting plate 14 in the circular groove, and fixing the reagent bottle 5 by the supporting structure, the device can meet the use of reagent bottles 5 of different sizes.

[0029] The specific operation process of the utility model is as follows: open the sealing cover 2 and place the reagent bottle 5 in the first circular hole, and use the supporting structure composed of the supporting rod 15, the elastic member 13 and the supporting plate 14 to support the reagent bottle 5. When all the reagent bottles 5 to be tested are placed in the first circular hole, the servo motor 10 is started to drive the circular plate 4 to reciprocate. The reciprocating rotation of the circular plate 4 drives the reagent bottle 5 to reciprocate and shake, and the stirring structure composed of the bearing 12, the stirring rod 6 and the arc plate 7 to reciprocate.

[0030] Furthermore, the stirring structure close to the rotating rod 11 rotates in the opposite direction to the stirring structure far from the rotating rod 11, so that no matter whether the reagent bottle 5 rotates counterclockwise or clockwise, there is a stirring structure around the reagent bottle 5 to stir the heated liquid around the reagent bottle 5, thereby ensuring that the stirring structure contacts the heated liquid around the reagent bottle 5 and heats the reagent bottle 5, and reduces the shaking amplitude of the water flow, thereby avoiding different heating effects on the reagent bottles 5 in different areas.
