[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0017] Please see Figure 1-4 As shown, this utility model is a tea quality testing device, comprising: Multifunctional food safety testing instrument 10; The Multifunctional Food Safety Detector 10, Model: NP-800 Pesticide Residue Rapid Detector, involves taking a sample and placing it in a cuvette. The cuvette is then inserted into the NP-800 detection slot. The built-in LED light source is activated at a wavelength of 410nm. The optical fiber at the bottom of the enzyme-labeled plate receives the transmitted light signal, which is converted into an electrical signal by a photoelectric sensor. The instrument's built-in standard curve absorbance value corresponds to the pesticide residue concentration, and the inhibition rate is automatically calculated. An inhibition rate ≥70% is considered positive (exceeding the standard), while ≤50% is considered negative (safe).
[0018] The guide assembly includes a support column 20, a support frame 22, a sleeve 23, a connecting rod 24, and an L-shaped limiting plate 25. The support column 20 is fixed in the middle of the detection chamber of the multi-functional food safety detector 10. The support frame 22 is sleeved on the lower end of the support column 20. The sleeve 23 is sleeved on the upper end of the support column 20, and its lower end is fixed on the support frame 22. One end of the connecting rod 24 is fixed on the outer ring of the support frame 22, and the L-shaped limiting plate 25 is fixed on the other end of the connecting rod 24. The guide assembly also includes a limiting plate 21, which is fixed to the top of the support column 20; The multifunctional food safety testing instrument 10 has twelve cuvette testing slots inside the testing chamber, which are arranged in a ring, with the support column 20 located in the middle of the ring; When placing a cuvette, the inner sides of the L-shaped limiting plate 25 should fit against the two sides connected to the detection groove. Support column 20 provides support, limit plate 21 provides limit, support frame 22 provides connection, sleeve 23 provides connection, connecting rod 24 provides connection, and L-shaped limit plate 25 provides limit.
[0019] Working principle: Fix the connecting rod 24 evenly on the support frame 22. Hold the sleeve 23 and put the support frame 22 and sleeve 23 on the support column 20 and fix them. Fix the limiting plate 21. Hold the cuvette and align the two adjacent sides of its lower end with the two inner sides of the L-shaped limiting plate 25. Slide it downwards and let it fall into the detection groove.
[0020] This step allows the cuvette to fall into the detection tank along a predetermined trajectory, improving detection efficiency and reducing operator fatigue.
[0021] Please see Figure 4-5 As shown, this embodiment, based on the above embodiment, further includes: The positioning component includes a support block 31, a first limiting groove 32, a second limiting groove 33, and a limiting strip 35. The support block 31 is fixed inside the detection chamber of the multi-functional food safety detector 10. The first limiting groove 32 and the second limiting groove 33 are respectively opened at both ends of the support block 31. The limiting strip 35 is fixed at one end of one of the L-shaped limiting plates 25. The positioning component also includes a mounting plate 30 and a limiting block 34. One end of the mounting plate 30 is fixed to one end of the support block 31 and is fixed in the detection chamber of the multi-functional food safety detector 10 by screws. The limiting block 34 is fixed to the upper ends of both sides of the support block 31. When a cuvette needs to be placed, the limiting strip 35 is inserted into the first limiting groove 32; when a cuvette needs to be removed, the limiting strip 35 is inserted into the second limiting groove 33. Mounting plate 30 is used to fix support block 31. Support block 31 provides support, first limiting groove 32 and second limiting groove 33 provide limiting, and limiting block 34 and limiting strip 35 provide positioning.
[0022] Working principle: When the cuvette needs to be placed, the limiting strip 35 is inserted into the first limiting groove 32. After the test is completed, the sleeve 23 is pulled upward. After the limiting strip 35 moves out of the first limiting groove 32, the sleeve 23 is rotated, which drives the support frame 22 and the connecting rod 24 to rotate, and then drives the limiting strip 35 to rotate. When the limiting strip 35 is attached to the limiting block 34 at the other end of the support block 31, the sleeve 23 is placed downward. At this time, the limiting strip 35 falls into the second limiting groove 33. At this time, the L-shaped limiting plate 25 is located between the two placement grooves, which does not affect the removal of the cuvette.
[0023] This step facilitates the rotation and positioning of the L-shaped limiting plate 25, preventing the L-shaped limiting plate 25 from affecting the removal of the cuvette.
