Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a food safety testing device. Background Technology

[0002] In today's society, as people's living standards continue to improve, their attention to food safety is increasing day by day. The frequent exposure of various food safety incidents not only seriously threatens consumers' health, but also has a great impact on the social and economic order. Accurate and efficient food safety testing devices have become an important guarantee for maintaining public health and stabilizing market order. They can detect harmful substances in food in a timely manner and ensure food safety from the source.

[0003] In the early days, food safety testing mainly relied on human sensory judgment and simple chemical analysis methods, but these methods had significant limitations. Human sensory judgment was highly subjective, and the experience and judgment standards of different testers varied, which easily led to misjudgments. With the continuous advancement of technology, existing food safety testing devices have adopted a variety of advanced technologies, which have significantly improved the accuracy and efficiency of testing. However, when testing multiple foods, it is necessary to sample and test the samples, but manual sampling is subject to personal subjectivity. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a food safety testing device, which aims to improve the existing technology that requires sampling and testing of samples, but manual sampling is subject to personal subjectivity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a food safety testing device, including a housing, a conversion mechanism is provided on the left side of the housing for exchanging samples, and a testing mechanism is provided inside the conversion mechanism for testing food.

[0006] The conversion mechanism includes an inspection chamber located on the top left side of the outer shell. A rotating pile is rotatably connected to the bottom of the inspection chamber. A power component is provided on the outer wall of the rotating pile. A placement block is fixedly connected to the top of the rotating pile. A placement groove is provided on the top of the placement groove. A positioning component is provided on the outer wall of the placement groove. An elastic component is provided on the inner wall of the inspection chamber. A disinfection component is provided on the top surface of the outer shell.

[0007] As a further description of the above technical solution:

[0008] The detection mechanism includes a limiting groove, which is formed on the inner wall of the inspection chamber. A rotating component is provided on the inner wall of the limiting groove. An operating component is provided on the bottom surface of the limiting groove. A knob is provided at the other end of the operating component. A support beam is provided on the outer wall of the rotating component. A detection head is rotatably connected to the other end of the support beam.

[0009] As a further description of the above technical solution:

[0010] The disinfection assembly includes a rotating door, one end of which is rotatably connected to the top surface of the outer casing, and an ultraviolet lamp is provided on the outer wall of the rotating door.

[0011] As a further description of the above technical solution:

[0012] The power assembly includes a motor, which is fixed to the bottom of the inspection chamber. A drive gear is fixedly connected to the output end of the motor, and a driven gear is meshed with the outer wall of the drive gear. The driven gear is fixed to the outer wall of the rotating pile.

[0013] As a further description of the above technical solution:

[0014] The elastic component includes a fixed cylinder, which is fixed to the inner wall of the inspection chamber, and a spring is provided on the inner wall of the fixed cylinder.

[0015] As a further description of the above technical solution:

[0016] The positioning component includes a positioning bead, the outer wall of which is slidably connected to the inner wall of the fixed cylinder, and the outer wall of the placement block is provided with multiple positioning holes.

[0017] As a further description of the above technical solution:

[0018] The operating component includes a mounting plate, which is fixed to the bottom of the inner wall of the limiting groove, and a worm gear is rotatably connected to the middle of the mounting plate.

[0019] As a further description of the above technical solution:

[0020] The rotating assembly includes a threaded rod, the two ends of which are rotatably connected to the inner wall of the limiting groove, and a worm gear is fixedly connected to the outer wall of the threaded rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the food sample for testing is placed in the placement slot at the top of the placement block. The motor is started, and the motor causes the rotating pile to rotate through the driving gear and the driven gear, that is, the placement block rotates. Then, the motor is turned off at random time, so that the placement block stops rotating. The spring pushes the positioning bead into the positioning hole. Each placement slot corresponds to one positioning hole. When the placement block stops rotating, multiple samples randomly appear below the detection head for testing, realizing simple random sampling detection.

[0023] 2. In this utility model, during testing, rotating the knob drives the worm gear to rotate, and the worm gear meshes with the worm wheel, i.e., the threaded rod rotates. One end of the support beam is threadedly connected to one end of the threaded rod. The support beam will not rotate under the restriction of the limiting groove, so that the support beam is displaced along the axial direction of the threaded rod, realizing the lifting and lowering of the support beam. After sampling is completed, rotating the knob causes the support beam to descend, and the detection head can detect the sample. Attached Figure Description

[0041] Working principle: The food sample is placed in the placement slot 206 on top of the placement block 205. The motor 2031 is started. The motor 2031 causes the rotating pile 204 to rotate through the driving gear 2032 and the driven gear 2033, that is, the placement block 205 rotates. Then, the motor 2031 is turned off at random time, so that the placement block 205 stops rotating. The spring 2082 pushes the positioning bead 2072 to lock into the positioning hole 2071. Each placement slot 206 corresponds to a positioning hole 2071. When the placement block 205 stops rotating, multiple samples randomly appear below the detection head 306 for detection, realizing simple random sampling detection.

[0042] During testing, rotating knob 303 causes the worm gear 3022 to rotate, which in turn meshes with the worm wheel 3042, causing the threaded rod 3041 to rotate. One end of the support beam 305 is threadedly connected to one end of the threaded rod 3041. The support beam 305 is not rotated due to the restriction of the limiting groove 301, allowing it to move axially along the threaded rod 3041, thus raising and lowering the support beam 305. After sampling is complete, rotating knob 303 causes the support beam 305 to descend, allowing the detection head 306 to test the sample.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
