Embodiment Construction
[0018] Below in conjunction with accompanying drawing and embodiment, content of the invention will be further described:
[0019] Such as figure 1 and figure 2 As shown, the detection portable device that can cool down contains a test box 14, and a halogen lamp 12 and a TiO2 nanocrystalline porous film electrode 11 are placed in the test box 14. The test element of test is provided with heavy metal test strip 13 under the outlet of silicon nitride ceramic bottle 500 for mixing liquid food sample and water in addition, and described silicon nitride ceramic bottle 500 for mixing liquid food sample and water Set in the test box 14, the test box 14 is made of polymer nanofiber heat-conducting material, the inner surface of the upper end of the test box 14 is covered with a heat dissipation metal sheet 11, and the upper end of the test box 14 is also the same The cooling cover 12 is connected. The cooling cover 12 is an arched structure with an upper end cover. The bottom surfa...

The invention discloses a portable detector capable of cooling. A cooling cover is an arch-shaped structure with an upper end cover; a part penetrating through the lower end of the cooling cover from the bottom surface of the upper end cover of the cooling cover is of a hole structure; the lateral surface of the cooling cover is provided with a plurality of through holes; the cooling cover sleeves and winds a testing box, and the upper end of the testing box and the upper end cover of the cooling cover are overlapped; the inner surface of the lateral part of the cooling cover keeps a certain distance from the outer surface of the lateral part of the testing box; the appearance of each through hole is in a clockwise offset shape or an anticlockwise offset shape; one edge of the projection of each through hole in the vertical direction is forward-arch-shaped; the other edge of the projection of each through hole in the vertical direction is backward-arch-shaped. The detector can be used for preventing the defect that the detection property of a portable heavy metal detector cannot keep the normal state because of the zooming of temperature due to that partial elements are always in the seal state of the portable heavy metal detector in the prior art.
Description
technical field [0001] The invention belongs to the technical field of detection portable devices for heavy metals in food, and in particular relates to a detection portable device capable of cooling down. Background technique [0002] Heavy metals are transmitted to the stomach through liquid food, which will cause digestive disorders in the stomach. In addition, the heavy metals delivered to the stomach often have to accumulate for a certain period before signs of digestive disorders appear, which makes it difficult to detect ingestion at the beginning. Heavy metals have been detected, which has a negative effect. Therefore, the detection of heavy metals in liquid food is extremely unusual for maintaining the hygiene of liquid food. [0003] At present, the general heavy metal detection methods mainly include spectrophotometry and stripping voltammetry, which require special equipment for detection. Such special equipment is not small in size and the cycle is not short, an...
