Description

Technical Field

[0001] The invention relates to the technical field of food safety detection, and in particular to a multifunctional food safety detector with detection platform cleaning function. Background Art

[0002] Food safety has always been a key issue of concern to people. As an important tool to ensure food safety, the functions and performance of food safety detectors have been continuously improved and perfected. Multifunctional food safety detectors are a kind of equipment that integrates multiple detection functions. They can quickly and accurately detect various harmful substances in food, including pesticide residues, heavy metals, additives, pathogenic bacteria, etc. In the past, food safety detectors were mainly based on a single function and could not meet the needs of the market.

[0003] With the development of science and technology and the increasing prominence of food safety issues, multifunctional food safety detectors have emerged. It can not only detect multiple harmful substances at the same time, but also analyze and process data through an intelligent testing platform to provide all-round protection for food safety. With the continuous advancement of science and technology, I believe that multifunctional food safety detectors will play an increasingly important role in the future and become an important tool for food safety monitoring.

[0004] After searching, the Chinese patent application number CN2021216101154 discloses a food safety detection and analysis device for Dorayaki, which relates to the field of food safety technology, including a detection device, a connecting groove, a connecting block, a suction cup and a card block. The utility model realizes the function of fixing the detection device by setting a detection device, a connecting groove, a connecting block, a suction cup and a card block. The detection device can be fixed on a desktop or platform to prevent the detection device from falling from the desktop and being damaged, thereby ensuring the normal progress of food safety detection work, improving the work efficiency of the detection personnel, and reducing economic losses. At the same time, the suction cup can be replaced simply and quickly, thereby improving the practicality of the food safety detection and analysis equipment. At the same time, by setting an installation groove, a protective shell, a limit block, a limit groove, a clamping rod and a buckle, the suction cup can be sealed and protected, and the suction cup is placed to prevent the suction cup from being contaminated with dust due to long-term exposure to the outside, thereby preventing the suction cup from losing its adsorption force. The food safety detection and analysis device for Dorayaki in the above-mentioned patent has the following shortcomings:

[0005] Although the overall device solves the problem of the suction cup being contaminated with dust due to the monitoring platform being exposed to the outside for a long time and prevents the suction cup from losing its adsorption force, the optical window in the detection hole will be contaminated with dust and dirt due to the frequent use of the cover, which not only affects the food detection results but also is difficult to clean.

[0038] When the semicircular shaft 805 rotates, it also drives the incomplete teeth 804 at the bottom to rotate, and the rotation of the incomplete teeth 804 drives the internal gear disk 801 to rotate. When the incomplete teeth 804 below the semicircular shaft 805 rotates a certain angle, its circumferential teeth gradually mesh with the rotating teeth 802, driving the rotating teeth 802 to rotate forward. When the circumferential teeth of the incomplete teeth 804 rotate and disengage from the rotating teeth 802, the rotating teeth 802 mesh with the internal teeth of the internal gear disk 801, driving the rotating teeth 802 to rotate in the reverse direction.

[0039] In order to clean the optical window 604 in the color dish tube placement box 602; Figure 3 , Figure 6 and Figure 7 As shown, the lifting mechanism 9 includes a fixed cylinder 901, a connecting ring 902, a guide column 903, a spiral hole 904, a guide shaft 905, a sponge sleeve 906, a connecting shaft 907, a wiping cotton 908, an annular groove 909 and a slide groove 910, and the connecting ring 902 is fixedly connected to the top circumference of the rotating gear 802, the fixed cylinder 901 is fixedly connected to the inner wall of one side of the chassis 2 through a bracket, the annular groove 909 is opened on the bottom circumference of the fixed cylinder 901, and the connecting ring 902 and the annular groove 909 form an annular sliding fit, the guide shaft 905 is fixedly connected to the top of the inner circle shaft of the rotating gear 802, and the spiral hole 904 is opened on the circumferential outer wall of the guide shaft 905;

[0042] When the rotating gear 802 rotates forward, the guide shaft 905 is driven to rotate. During the rotation process, the spiral hole 904 on the circumference of the guide shaft 905 also rotates, driving the guide column 903 to slide inside it.

One end with the sponge cover 906 penetrates into the color dish tube placement box 602 from the bottom, and the wiping cotton 908 on one side of the sponge cover 906 can just wipe the optical window 604 in the color dish tube placement box 602.

During this process, the L-shaped guide rod 806 slides with the groove 809, and the circumference of the semicircular shaft 805 and the semicircular groove 808 fit each other, and the intermittent rotating wheel 807 is connected to the rotating rod at the bottom of the sample chamber 6;

[0044] When the semicircular shaft 805 rotates, the incomplete teeth 804 at the bottom thereof are driven to rotate, and the rotation of the incomplete teeth 804 drives the internal gear plate 801 to rotate. When the incomplete teeth 804 below the semicircular shaft 805 rotates a certain angle, its circumferential teeth gradually mesh with the rotating teeth 802, driving the rotating teeth 802 to rotate forward. When the circumferential teeth of the incomplete teeth 804 rotate and disengage from the rotating teeth 802, the rotating teeth 802 mesh with the internal teeth of the internal gear plate 801, driving the rotating teeth 802 to rotate in the reverse direction.

[0045] When the rotating tooth 802 rotates forward, it drives the guide shaft 905 to rotate. During the rotation process, the spiral hole 904 on the circumference of the guide shaft 905 also rotates, driving the guide column 903 to slide inside it. At the same time, the guide column 903 makes a linear motion in the slide groove 910 of the fixed cylinder 901, which promotes the connecting shaft 907 in the guide shaft 905 to extend out from the inside. One end with the sponge cover 906 penetrates into the color dish tube placement box 602 from the bottom, and the wiping cotton 908 on one side of the sponge cover 906 can just wipe the optical window 604 in the color dish tube placement box 602. When the rotating tooth 802 rotates reversely, the connecting shaft 907 with the sponge cover 906 descends and is led out from the bottom of the color dish tube placement box 602.
