[0002] Apigenin, an important natural active ingredient, is widely found in a variety of plants and exhibits significant antioxidant, anti-inflammatory, and anti-cancer activities. Its quantitative detection is crucial for drug development, food quality control, and nutritional research. Traditional apigenin detection methods, such as high-performance liquid chromatography (HPLC), rely on complex laboratory equipment and cumbersome procedures. While these methods offer high accuracy, they are expensive, complex, and time-consuming, making them difficult to meet the demands of rapid on-site testing.
[0003] Although some portable apigenin detection devices already exist on the market, most lack specificity in their light source selection and are unable to effectively filter out stray light, making the detection signal susceptible to interference and affecting the accuracy of the results. Furthermore, the structural design of some devices fails to fully consider the user experience, resulting in complex operation and the need for professional personnel, which limits their application in non-professional environments. Furthermore, the high manufacturing cost also limits the popularity of these devices, making them unaffordable for many small and medium-sized laboratories and grassroots units. Utility Model Content

[0009] The beneficial effects of the utility model are as follows:
[0010] 1. The integrated design is easy and quick to operate, and detection can be performed without complex settings, which reduces the requirements for professional skills of operators and is convenient for non-professionals to use.

A placement table 3 for placing a test tube 2 is provided inside the operator 1, and an inner groove 31 for placing the test tube 2 is opened on the placement table 3.

[0019] like Figure 1 and Figure 2 As shown, in this embodiment, a driving rod 7 is fixed to the bottom of the placement table 3, a chassis 8 is fixed to the bottom of the inner wall of the operator 1, a micro motor 9 is installed on the top of the chassis 8, and the output end of the micro motor 9 is connected to the driving rod 7; the placement table 3, the photosensitive converter, the dial 6 and the sensing lever 5 are provided in plurality, and a driven rod 10 is fixed to the bottom of the placement table 3 that is not connected to the driving rod 7, and a central spur gear 11 is fixed to the outer side surface of the driving rod 7, and a driven spur gear 12 meshing with the central spur gear 11 is fixed to the outer side surface of the driven rod 10, and an outer meshing disk 13 is rotatably connected to the inner wall of the operator 1, and the outer meshing disk 13 is meshed with multiple driven spur gears 12, and the bottom of the driven rod 10 is rotatably connected to the chassis 8; a balancing disk 14 is fixed to the inner wall of the operator 1, and the placement table 3 passes through the balancing disk 14 and is rotatably connected to the balancing disk 14.
[0020] The working principle of this utility model is as follows:
[0021] The detection process begins with light emitted by a light source (typically a built-in LED or other stable light source). This light passes through filter 41. Filter 41 selects light with the characteristic absorption wavelength of apigenin, effectively eliminating interference from light of other non-target wavelengths. The light that passes through filter 41 then strikes photoresistor 42. Photoresistor 42 is a component that changes its resistance value based on changes in the intensity of the received light. When the light intensity changes (i.e., different apigenin concentrations in test tube 2 result in different amounts of light absorption), the resistance of photoresistor 42 also changes, generating an electrical signal inversely proportional to the light intensity. This signal is then amplified and transmitted to the control circuit, which then connects to sensing lever 5. Sensing lever 5 adjusts its position based on the changes in the electrical signal, moving along the indicator dial 6. The corresponding apigenin concentration value is marked on dial 6, and the user can directly read the value indicated by the pointer to obtain the test result.
[0022] Manipulator 1 houses a micromotor 9 connected to a central spur gear 11 via a drive rod 7. This drives the central spur gear 11 in rotation, which in turn, through the meshing of a driven spur gear 12 and an outer engagement disc 13, drives the multiple placement platforms 3 in synchronous rotation. This allows users to load and mix multiple test tubes 2 at once, automatically completing their individual testing, reducing the number of mixing and transfer steps and effectively improving testing efficiency.
