Technical Field

[0001] The utility model relates to the technical field of food safety detection, in particular to an immunochromatographic analyzer. Background Art

[0002] When conducting food safety testing, we can quickly and accurately detect harmful substances and pesticide residues in food through immunochromatography. This method is based on the principle of antigen-antibody specific binding. The substance to be tested is combined with a specific antibody to form an antigen-antibody complex, and then the complex is separated and quantitatively detected through chromatography technology.

[0003] The advantages of immunochromatography are that it is fast, simple, highly sensitive, and does not require expensive instruments and equipment, so it is widely used in the field of food safety testing. At the same time, this method can also detect a variety of harmful substances, such as heavy metals, additives, microorganisms, etc., providing comprehensive protection for food safety.

[0004] However, when the immunochromatographic analysis method is used for testing, it takes a certain amount of time for the reaction to complete, and there are many types and quantities of products to be tested in large supermarkets, which causes the disadvantage of inconvenience of the testing method.

[0005] Based on this, the utility model designs an immunochromatographic analyzer to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an immunochromatographic analyzer to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising a shell, a clearance hole is opened on the shell, a support frame is fixedly arranged in the clearance hole, and a detection block is placed on the support frame; a placement groove is fixedly arranged in the shell, and there are two placement grooves, circuit boards are placed in the two placement grooves, and a camera, a fill light board and a communication module are fixedly arranged on the circuit board.

[0008] By adopting the above technical solution, the detection block is placed in the support frame, and the colloidal gold reaction on the detection block is photographed and identified by using a camera, and finally transmitted to a mobile device for viewing through a communication module.

[0009] Preferably, the shell is made of opaque material.

[0010] By adopting the above technical solution, the interference of ambient light on the camera is reduced, and the camera's shooting accuracy of the color block on the detection block is improved, thereby achieving the effect of improving the detection accuracy.

[0011] Preferably, the fill light panel and the circuit board form an angle α, and the range of α is 30-60°.

[0012] By adopting the above technical solution, it is avoided that the light of the fill light board is reflected on the camera through the detection block, which causes the detection result captured by the camera to be abnormal.

[0013] Preferably, two fill light panels are provided, and the two fill light panels are fixedly arranged on both sides of the camera.

[0014] By adopting the above technical solution, the provision of two fill light panels increases the brightness of the housing, so that the camera has sufficient ambient light when shooting.

[0015] Preferably, a pressing block is fixedly provided on the support frame, and a pressing hole is provided on the detection block; when the detection block is placed on the support frame, the pressing block presses against the pressing hole.

[0016] By adopting the above technical solution, when the detection block is placed in the support frame, the pressing block makes the detection block press tightly in the support frame, avoiding abnormal detection results caused by shaking of the detection block when the camera is shooting.

[0017] In summary, the present application has the following beneficial technical effects: by placing the test paper on the detection block, and then smearing the substance to be tested and the reagent on the test paper, the detection block can be placed on the support frame and wait for its reaction; after a certain period of time, the color of the colloidal gold on the detection block after the reaction is photographed by the camera, and after obtaining the presence or absence of the measured substance, it is transmitted to the mobile device through the communication module, which has the advantage of easy detection.
