Abstract
Description
Technical Field
[0001] The utility model relates to the field of fruit and vegetable detection, in particular to a fruit and vegetable vitamin C rapid detection card. Background Art
[0002] Fruits and vegetables refer to vegetables and fruits in general. Fruits and vegetables are the main components of the food composition of residents' diet. They are rich in vitamins, inorganic salts and dietary fiber necessary for the human body, and contain very little protein and fat. For the detection of fruits and vegetables, it is necessary to test the vitamin C content of different fruits and vegetables, so as to know the vitamin C content of different fruits and vegetables, which is convenient for people to know the nutritional ratio of daily diet. The detection of vitamin C requires the use of test cards. The test card is based on the principle that vitamin C reacts with o-phenylenediamine to generate colored compounds. The vitamin C content in fruits and vegetables is quickly detected by colorimetry. By placing fruit and vegetable juice on the test card, the color of the test card changes and the vitamin content is known according to the depth of the color.
[0003] The existing technology has the following problems:
[0004] The fruit and vegetable vitamin C rapid test card in the prior art is not convenient to use. When the fruit and vegetable juice is placed on the test card, the juice is prone to slide due to the lack of a barrier structure, so that the vitamin C contained in the juice cannot fully react with the o-phenylenediamine on the test card to generate a colored compound, and therefore the vitamin C content concentration cannot be accurately determined. Summary of the invention
[0005] In view of the deficiencies in the prior art, the utility model provides a fruit and vegetable vitamin C rapid detection card, which has the advantages of being easy to use and solves the problems in the above-mentioned background technology.

[0007] A cover plate is fixedly connected to one side of the connection block, a magnetic block is fixedly installed on the top of the detection bucket, and the inner wall of the handle rod is movably connected to the detection card body, so that the detection card can be easy to use. The detection card body is installed inside the handle rod in a simple and quick way, and the detection bucket is used to collect fruit and vegetable juice and cooperate with the detection card body to perform reaction detection. During the process, the problem of fruit and vegetable juice sliding and the problem of the detection card body falling off can be avoided, thereby avoiding the waste of fruit and vegetable juice and the problem of inaccurate vitamin C detection, and meeting people's use needs.
[0008] Preferably, a connecting groove is provided on the top of the detection bucket, and the detection bucket is fixedly connected to the magnetic block through the connecting groove. The connecting groove allows the magnetic block to be installed in a groove, thereby ensuring that a gap is avoided between the cover plate and the detection bucket when the magnetic block adsorbs the cover plate.
[0009] Preferably, the inner wall of the handle is provided with a mounting groove, and the handle is movably connected to the detection card body through the mounting groove, and the mounting groove enables the detection card body to be quickly inserted and removed from the handle, thereby facilitating the disassembly and assembly of the detection card body.
[0010] Preferably, the front surface of the fixed block is movably connected with a movable shaft, and the fixed block is movably connected to the connecting block through the movable shaft, and the movable shaft allows the connecting block to move at an angle to cooperate with the rapid opening and closing of the cover plate.
[0011] Preferably, one end of the movable shaft is fixedly connected with an anti-dropping block, and the diameter of the anti-dropping block is larger than the diameter of the movable shaft. The anti-dropping block can prevent the movable shaft from falling off and causing the cover plate and other structures to fall off the entire equipment.
[0012] Preferably, the bottom of the handle is fixedly connected with an elastic band, and the elastic band enables people to wear the entire detection device on their hands for easy carrying.
[0013] Compared with the prior art, the utility model provides a fruit and vegetable vitamin C rapid test card, which has the following beneficial effects:
