[0024] 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.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] Reference Figures 1-4 This utility model provides a cup-type milk quality testing instrument, including:

[0028] The cup body 2 has a light-transmitting bottom surface, and the outer shell 1 is fixedly fitted onto the outside of the cup body 2. The outer shell 1 is equipped with a detection and display component.

[0029] The base 3 and the outer shell 1 are placed on top of the base 3. The top of the base 3 is equipped with a light-emitting component and a spectral detection component. The bottom of the cup body 2 is tightly fitted with the top of the base 3. The light-emitting component and the spectral detection component are respectively set through the bottom of the cup body 2 and correspondingly set inside the cup body 2 to realize optical path transmission and signal detection.

[0030] The electronic control component is located inside the base 3. The detection and display component, the spectrum detection component, and the temperature sensor 9 are electrically connected to the electronic control component.

[0031] The main function of the cup body 2 is to hold the milk. Its high light transmittance at the bottom ensures the transmission of detection light, thereby guaranteeing the accuracy and stability of the detection structure. The main function of the outer shell 1 is to stably support the cup body 2 and place it smoothly on the base 3. Simultaneously, the side walls and bottom of the outer shell 1 and the base 3 enclose the bottom of the cup body 2, enhancing its light-blocking properties and preventing interference from external light. The main function of the light-emitting component is to emit visible / near-infrared light into the milk for detection. The main function of the spectral detection component is to detect the intensity of reflected light, analyzing the milk's quality based on the intensity of the reflected light. Overall, this milk detector features a compact and portable design, is simple and efficient to operate, and can quickly provide information on the internal quality of milk. It is widely applicable to various production and daily life scenarios, helping to ensure production safety and improve the quality of life.

[0032] The design was further optimized. The cup body 2 is made of glass, and the high light transmittance of glass ensures the accuracy of the test results. The outer shell 1 is made of plastic, which wraps around the cup body 2. The high friction of the plastic outer shell 1 ensures stability and comfort when holding the cup.

[0033] In a further optimized design, a connecting seat 12 is fixedly connected to the top of the base 3, the bottom of the cup body 2 abuts against the top of the connecting seat 12, and a detection groove 6 is opened downward on the top of the connecting seat 12. The side wall of the detection groove 6 is inclined and forms a frustum structure, and the light-emitting component and the spectral detection component are respectively set in the detection groove 6.

[0034] The scheme is further optimized. The light-emitting component includes several fixing holes 15. The several fixing holes 15 are evenly spaced around the side wall of the detection groove 6. Light-emitting diodes 7 are fixedly connected in the several fixing holes 15 respectively. The several light-emitting diodes 7 form a 45-degree angle with the top of the detection groove 6.

[0035] The spectral detection assembly includes a photoelectric sensor 8 fixedly connected to the bottom of the detection slot 6.

[0036] like Figure 1 and Figure 4As shown, four sets of light-emitting diodes 7 are set in the detection groove 6. All four sets of light-emitting diodes 7 are set to be tilted at 45 degrees to the inside of the detection groove 6 so as to evenly irradiate light from the bottom of the cup body 2 into the cup body 2.

[0037] like Figure 4 As shown, the bottom of the outer shell 1 extends downward a certain distance, so that when the outer shell 1 is placed to the top edge of the base 3, the bottom of the cup body 2 just touches the top of the connecting seat 12, so that the light from the LED 7 can directly shine into the cup body 2, while the outer shell 1 blocks the light from the connecting seat 12 and the bottom of the cup body 2.

[0038] To further optimize the design, a temperature sensor 9 is fixedly connected to the bottom of the detection tank 6.

[0039] To further optimize the scheme, in order to compensate for the detection results when measuring the temperature of milk samples, a thermopile temperature sensor was selected for temperature sensor 9.

[0040] The solution was further optimized so that the test display component includes a display screen 4 fixedly connected to the side wall of the housing 1, and the display screen 4 is electrically connected to the electronic control component through a detachable interface component.

[0041] like Figure 1 As shown, a mounting groove 5 is provided on the side wall of the outer casing 1 for mounting the display screen 4. The display screen 4 is a flexible screen, which is installed to fit the curvature of the outer wall of the outer casing 1.

[0042] Further optimization of the solution: the detachable interface component includes an electrical connection point 11 that is vertically fixed to the side wall of the housing 1, and an electrical connection port 10 that is opened downward at the top of the connector 12, with the connection point 11 and the connection port 10 being compatible.

[0043] like Figure 1 and Figure 3 As shown, the display screen 4 is connected to the electrical connection point 11 via a data connection cable. When the cup body 2 is placed on the base 3, the connection point 11 is aligned with the connection port 10. After the cup body 2 is placed on the connection seat 12, the connection point 11 is plugged into the connection port 10 to realize the signal transmission between the electronic control components and the display screen 4.

[0044] The scheme is further optimized. The electronic control components include a control motherboard 13 fixedly connected in the base 3, and light-emitting diodes 7, photoelectric sensors 8, temperature sensors 9 and display screens 4 are electrically connected to the control motherboard 13.

[0045] To further optimize the solution, the control motherboard 13 can be a PCB motherboard.

[0046] In a further optimized design, a battery 14 is also fixedly connected inside the base 3. The battery 14 is used to supply power to the control motherboard 13, the light-emitting diode 7, the photoelectric sensor 8, the temperature sensor 9, and the display screen 4.

[0047] The working process of this embodiment is as follows:

[0048] First, the detector of this invention is calibrated using a standard calibration whiteboard. Specifically, the light-emitting diodes 7 are lit in sequence, their light intensity information is collected and stored in the control motherboard 13, and the display screen 4 displays "calibration successful".

[0049] After the milk sample is poured into the cup 2, the light-emitting diodes 7 light up again and the photoelectric sensor 8 collects the reflected light intensity information of the milk sample in the cup 2. By comparing the light intensity information of the standard calibration whiteboard initially saved in the control motherboard 13 with the light intensity information reflected by the milk, the internal quality prediction model of the milk is imported to obtain relevant information on the internal quality of the milk. The data is then transmitted to the display screen 4 to display the results.

[0050] Example 2:

[0051] The only difference between this embodiment and Embodiment 1 is that a communication unit electrically connected to the control motherboard 13 is added to the base 3. This communication unit supports Bluetooth connectivity, can be paired with a mobile phone, and enables remote storage of detection data for easy viewing and analysis by the user.

[0052] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0053] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
