Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and fig. 2, the utility model discloses a food pigment chemical inspection device, including examining test table 6, flask, mount 14, extraction filtration 3 and operation structure, examine the mesa level setting of test table 6. The body 22 of the flask is clamped and fixed on the fixing frame 14, and the bottom of the fixing frame 14 is hinged on the detection table 6. The flask comprises a spherical body 22 and a cylindrical neck 21, a mouth 23 extending to the outside of the fixing frame 14 is formed at the bottom of the body 22 of the flask, and the mouth 23 inclines towards the table surface of the detection table 6. The end of the bottle mouth 23 far away from the bottle body 22 is provided with a bottle cap 5, and the end of the bottle mouth 23 can be closed by the bottle cap 5. The extraction filter structure 3 comprises a hollow cannula 34, a filter screen 35 and a rubber blanking cap 33. The filter screen 35 is clamped at the lower port of the insertion tube 34 through a clamping sleeve, the tube body of the insertion tube 34 is in sliding fit with the bottle neck 21, and the lower end of the insertion tube 34 is inserted into the bottle body 22 of the flask. The upper end of the cannula 34 is threadedly connected to a rubber blanking cap 33. A ring of flange 331 is formed on the lower portion of the rubber packing cap 33 along the circumferential direction, the cross section of the flange 331 is in the shape of a right trapezoid, and the oblique side of the right trapezoid inclines towards the insertion tube 34; the middle part of rubber shutoff lid 33 is opened has the feed port, and this feed port intercommunication intubate 34, and it has rubber buffer 32 to peg graft in the feed port simultaneously, utilizes rubber buffer 32 can seal the feed port, utilizes the feed port simultaneously can put into the intubate 34 food and extraction reagent that awaits measuring.

As shown in fig. 1 and 2, when the cannula 34 is inserted into the body 22 from the neck 21 of the flask, the filter mesh 35 closes the lower port of the cannula 34. On the other hand, the rubber cap seals the upper end of the insertion tube 34, and the inner circumferential surface of the flange 331 of the rubber cap 33 is pressed against the neck 21 of the flask, thereby fixing the insertion tube 34 to the flask. The operation structure comprises an operation rod 11, a connecting rod 13 and a tension spring 12, wherein the lower end of the operation rod 11 is hinged with the detection table 6. One end of the connecting rod 13 is hinged with the middle part of the operating rod 11, and the other end of the connecting rod 13 is hinged with the fixed frame 14. One end of the tension spring 12 is fixedly connected with the lower end of the operating rod 11, and the other end of the tension spring 12 is fixedly connected with the fixed frame 14. As shown in FIG. 1, the operating rod 11, the connecting rod 13, the fixing frame 14 and the detecting table 6 are combined to form a movable parallelogram structure.

In specific practice, the rubber stopper 32 is pulled out from the rubber cap 33. Then the food to be detected is put into the inserting tube 34 through the feeding hole, and the food falls on the filter screen 35 after entering the inserting tube 34. The extraction reagent is then added to the cannula 34 through the inlet port and flows into the body 22 of the flask through the cannula 34 and the filter screen 35, which is now immersed in the extraction reagent in the body 22. A rubber stopper 32 is inserted into the feeding hole of the rubber sealing cover 33, and the inserting tube 34 can be pulled up and down along the bottleneck 21 of the flask, so that the pigment extraction of the food can be completed as soon as possible. After the pigment extraction from the food is completed, the bottle cap 5 on the bottle mouth 23 is opened, and then the operating lever 11 is pushed to rotate. The operating rod 11 overcomes the action of the tension spring 12 and pushes the fixing frame 14 to rotate by the connecting rod 13 at the same time of rotating until the pigment extracting solution in the flask can be poured out through the bottle mouth 23. After the pigment extracting solution in the flask is poured, the operating rod 11 is loosened, the operating rod 11, the connecting rod 13 and the fixing frame 14 are restored to the original positions under the action of the elastic force of the tension spring 12, and then the bottle mouth 23 is covered with the bottle cap 5.

In the optimized scheme, the bottle cap 5 arranged on the bottle mouth 23 is not the only option. If the valve 4 is arranged on the bottle mouth 23, the opening and closing of the port of the bottle mouth 23 are controlled by the valve 4, which is more beneficial for the operation of experimenters. In the present case, the filter screen 35 that is selected is preferably a filter cloth because the filter cloth is not easy to react with the extraction reagent. To facilitate removal of the rubber stopper 32 from the rubber cap 33, a pull ring 31 is fixedly mounted on the rubber stopper 32.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
