[0027] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0029] Combination Figure 1 and Figure 2 As shown, this disclosure provides a beverage freshness detection device 100 (hereinafter referred to as detection device 100 for ease of description), including: a placement base 110, a sensor 120, and a control device 600. The placement base 110 is detachably installed on the door of a refrigerator, and at least one placement position 111 for placing beverages is provided on the placement base 110. The sensor 120 is disposed on the placement base 110 and is used to acquire at least one of the turbidity value and the color value of the beverage to be detected. The control device 600 is electrically connected to the sensor 120 and is used to determine the freshness of the beverage to be detected based on at least one of the turbidity value and the color value of the beverage.

[0030] Specifically, the placement base 110 is a loading component for placing beverages. The refrigerator door is the area where beverages are most frequently taken out and put in, and the door space has a high rate of idle space. Installing the placement base 110 on the refrigerator door can avoid occupying the internal storage space of the refrigerator.

[0031] Furthermore, by detachably installing the placement base 110 onto the refrigerator door, it can be easily operated when the placement base 110 needs cleaning and maintenance or when the sensor 120 installed inside the placement base 110 malfunctions.

[0032] Specifically, each placement slot 111 can hold one beverage. The design of multiple placement slots 111 allows for the simultaneous testing of the freshness of multiple beverages, improving testing efficiency and meeting users' needs for testing multiple beverages at once. The shape and size of the placement slots 111 are designed based on common beverage specifications to ensure that different types of beverages can be stably placed in each slot, preventing the beverages from shaking or tipping over during testing and affecting the accuracy of the test results.

[0033] It is understandable that a sensor 120 is provided in each placement position 111 of the placement base 110.

[0034] Optionally, the sensor 120 includes a turbidity detector 1201 and a color detector 1202.

[0035] Specifically, turbidity is an indicator of the suspended particulate matter content in a beverage and is an important factor in determining its freshness. For example, in some fruit juices, fruit particles may settle or spoil over time, causing changes in turbidity. Similarly, dairy products such as milk will experience increased turbidity if contaminated with bacteria or spoiled. Therefore, a sensor 120 capable of detecting the turbidity value of the beverage needs to be installed on the base 110 to preliminarily determine whether the beverage has spoiled or its quality has declined.

[0036] Optionally, the turbidity detection element 1201 uses optical principles (light scattering and light transmission methods) for detection. During detection, the turbidity detection element 1201 emits light of a set wavelength that passes through the beverage, and then measures the intensity of the light transmitted through the beverage or the intensity of the scattered light. Since suspended particulate matter scatters and absorbs light, the intensity of the light transmitted through the beverage or the intensity of the scattered light is closely related to the turbidity value of the beverage. By converting the detected light signal into an electrical signal and performing corresponding conversion calculations, the turbidity value of the beverage can be determined.

[0037] Specifically, color is also an important factor in judging the freshness of beverages. Different beverages have different color characteristics when fresh, but the color may change over time or as the beverage spoils. For example, fresh orange juice is a bright orange, but if it spoils, the color may darken or separate. Similarly, fresh green tea is a clear, tender green, but if left for too long or spoiled, it may turn yellow or become cloudy. Therefore, a sensor 120 for detecting the color value of the beverage needs to be installed on the base 110 to further assist in judging the freshness of the beverage.

[0038] Optionally, the color detection component 1202 is a color sensor. The color sensor can sense the color information of light reflected or transmitted from the surface of the beverage and convert it into digital signals. These digital signals can represent the intensity values ​​of the beverage in different color channels such as red, green, and blue. By performing corresponding conversion operations on the intensity values, the color value of the beverage can be obtained, such as Lab value, RGB value, or HSV value.

[0039] Specifically, the control device 600 can be a separate control chip or it can be directly integrated into the refrigerator's control device 600. By electrically connecting the control device 600 to the sensor 120, the control device 600 can receive at least one of the turbidity value and color value of the beverage to be tested, and determine the freshness of the beverage to be tested according to an internally preset algorithm or program.

[0040] The beverage freshness detection device 100 provided in this embodiment includes a placement base 110, a sensor 120, and a control device 600. The placement base 110 is detachably installed on the refrigerator door and has multiple placement slots 111 for placing beverages. The sensor 120 is disposed on the placement base 110 and is used to detect the color value and / or turbidity value of the beverage to be tested in the placement slot 111. The control device 600 is electrically connected to the sensor 120 and can determine the freshness of the beverage based on the color value and / or turbidity value. This allows for the periodic detection of changes in the freshness of the beverage during storage due to various factors. Compared to static monitoring methods based on shelf life and storage time in related technologies, this improves the accuracy of beverage freshness detection.

[0041] In some embodiments, the size of the placement position 111 of the base 110 is adjustable.

[0042] Understandably, beverages come in a variety of sizes and shapes, including slender mineral water bottles, short and stout juice bottles, and cylindrical carbonated beverage bottles. The adjustable placement slot 111 can accommodate beverages of different diameters and heights.

[0043] Optionally, retractable mechanical components, such as slide rails or telescopic rods, can be provided at the edge or inside of the placement position 111. These mechanical components can be manually operated to change dimensional parameters such as the length, width, or diameter of the placement position 111. For example, slide rails can be provided on both sides of the placement position 111, with sliding baffles mounted on the rails. The width of the placement position 111 can be adjusted by moving the position of the baffles.

[0044] Alternatively, the inner wall of the placement compartment 111 can be made of a flexible material, such as rubber or silicone. When beverages of different sizes are placed inside, the flexible material will deform according to the shape and size of the bottle, thus automatically adapting to the size of the beverage bottle.

[0045] In this embodiment, by providing an adjustable placement position 111 on the placement base 110, the placement base 110 can accommodate beverages of different diameters and heights, making it easier to arrange the positions of multiple beverages more reasonably and improving the efficiency of space utilization.

[0046] Combination Figure 3 As shown, in some embodiments, a limiting part 112 is provided in the placement position 111 of the placement base 110 for limiting the beverage to be tested.

[0047] Specifically, in the process of detecting the freshness of a beverage, the sensor 120 needs to accurately detect the turbidity and / or color values ​​of the beverage. If the beverage shakes within the placement position 111, it will cause the position of the detection light to shift, resulting in inaccurate detection of the turbidity and / or color values, thus affecting the judgment of the beverage's freshness. By setting the limiting part 112, it can fit tightly against the beverage bottle, firmly fixing the beverage within the placement position 111, reducing shaking, and ensuring the accuracy of the detection.

[0048] In this embodiment, a limiting part 112 is provided within the placement position 111. This allows for the limiting of the beverage bottle body, improving the stability of the beverage to be tested placed in the placement base 110.

[0049] In some embodiments, the control device 600 is configured to: identify the beverage category of the beverage to be tested; determine a target lookup table corresponding to the beverage category; obtain at least one of the turbidity value and color value of the beverage to be tested in the placement position 111; and determine the beverage freshness corresponding to at least one of the turbidity value and color value of the beverage to be tested based on the target lookup table.

[0050] Specifically, an image acquisition device is installed inside the refrigerator. The control device 600 can acquire an image of the appearance of the beverage to be tested through the image acquisition device, and then identify the beverage category of the beverage to be tested based on the appearance image.

[0051] Understandably, different types of beverages possess different physical and chemical properties, and their normal ranges for turbidity and color values, as well as the patterns of change with freshness, vary. For example, fresh milk and fresh fruit juice exhibit significant differences in turbidity and color, and their patterns of turbidity and color change during spoilage also differ. Therefore, it is necessary to first identify the type of beverage to be tested.

[0052] Optionally, identifying the beverage category of the beverage to be detected includes: acquiring an appearance image of the beverage to be detected; extracting text features, color features, and packaging features from the appearance image; and determining the beverage category of the beverage to be detected based on at least one of the text features, color features, and packaging features.

[0053] Specifically, the target reference table is a pre-defined reference standard that specifies the range of turbidity and color values ​​for a certain beverage category at different levels of freshness.

[0054] Specifically, the data storage space of the control device 600 contains a database of target lookup tables for various beverage categories. Once the beverage category to be detected is identified, the corresponding target lookup table for that beverage category is quickly and accurately found from the numerous stored target lookup tables according to the preset mapping relationship.

[0055] For example, as shown in Table 1, there is a target comparison table for the beverage categories of black tea, green tea, and orange juice.

[0056] Table 1

[0057] Specifically, the control device 600 is electrically connected to the sensor 120, and the sensor 120 acquires at least one of the turbidity value and color value of the beverage to be tested in the placement position 111.

[0058] Specifically, after obtaining the turbidity and color values ​​of the beverage to be tested, they are compared and analyzed with the data in a target reference table to determine the freshness of the beverage. For example, if the beverage is orange juice, and the turbidity value is 0.5, and the color values ​​are L = 50, a = 17.2, and b = 82.5, then the freshness of the beverage to be tested can be determined to be fresh.

[0059] In this embodiment, for the beverages to be tested stored in the refrigerator, their turbidity and color values ​​can be periodically measured. Then, based on the turbidity and color values, a match can be made with a target mapping table corresponding to the beverage category to determine the freshness of the beverage. This allows for the periodic detection of changes in beverage freshness caused by various factors during storage. Compared to static monitoring methods based on shelf life and storage duration in related technologies, this improves the accuracy of beverage freshness detection.

[0060] Combination Figures 1 to 3 As shown, in some embodiments, the detection device 100 further includes a light source 130. The light source 130 is disposed on the placement base 110 and electrically connected to the control device 600, and is used to illuminate the beverage to be detected.

[0061] Specifically, the base 110 is the component that supports the beverage. By mounting the light source 130 on the base 110, the light can be applied directly to the beverage. The light can evenly illuminate all parts of the beverage, ensuring that both the bottle and the liquid inside receive sufficient illumination, thus providing favorable conditions for subsequent turbidity and color testing.

[0062] Specifically, when detecting the turbidity and color values ​​of a beverage, the light source 130 can illuminate the beverage to increase its brightness. For turbidity detection, sufficient light makes suspended particles in the beverage more clearly visible, allowing the sensor 120 to more accurately capture the scattered light signals from these particles, thus obtaining a more precise turbidity value. For color detection, bright light allows the beverage's color to be presented more realistically and vividly, enabling the sensor 120 to more accurately identify and quantify the beverage's color characteristics, reducing color detection errors caused by insufficient or uneven lighting.

[0063] Specifically, after determining the freshness of the beverage to be tested, the light component 130 can also display light of a target color corresponding to the freshness of the beverage. This intuitive visual feedback allows users to quickly understand the freshness of the beverage. For example, green light can indicate that the beverage is fresh, red light indicates that the beverage is not fresh, and yellow light indicates that the freshness of the beverage cannot be determined. In this way, users can quickly decide whether to drink the beverage simply by observing the color of the light component 130.

[0064] In this embodiment, by setting the light element 130 on the base 110, the accuracy of detecting the turbidity value and color value of the beverage is improved, and the user's understanding of the freshness of the beverage is enhanced.

[0065] In some embodiments, the detection device 100 further includes a beverage freshness display device. The beverage freshness display device is disposed on the refrigerator door and is used to display the freshness of the beverage to be tested.

[0066] Specifically, by installing a beverage freshness display device on the refrigerator door, after the control device 600 determines the freshness of the beverage to be tested, the freshness of the beverage can be displayed through the display device, so that users can intuitively understand the freshness of the beverage in the refrigerator.

[0067] This disclosure provides a method for detecting the freshness of a beverage. This method is applied to the beverage freshness detection device described above, and the executing entity of this method is the control device of the beverage freshness detection device. Figure 4 As shown, the detection method includes: S401, The control device identifies the beverage category of the beverage to be tested.

[0068] S402, The control device determines the target lookup table corresponding to the beverage category.

[0069] S403, after the refrigerator door has been closed for a set period of time, the control device acquires at least one of the turbidity value and color value of the beverage to be tested in the placement position.

[0070] Specifically, when the refrigerator door is first closed, the beverage to be tested may move around, and environmental parameters such as temperature and humidity inside the refrigerator may fluctuate. These factors can all affect the accuracy of the beverage's turbidity and color values. Therefore, it is necessary to collect the beverage's turbidity and color values ​​in the placement position on the base only after the refrigerator door has been closed for a set period of time.

[0071] Optionally, the duration can be set from 30 min to 60 min.

[0072] Optionally, the turbidity and color values ​​of the beverage can be collected every 1 to 2 hours. If the refrigerator door is not opened during this period, the turbidity and color values ​​of the beverage can be collected directly without waiting for the set time.

[0073] Optionally, when acquiring the turbidity and / or color values ​​of the beverage to be tested in the placement position, the light fixture can be controlled to illuminate the beverage to be tested first.

[0074] S404, the control device determines the freshness of the beverage based on a target lookup table, which corresponds to at least one of the turbidity value and color value of the beverage to be tested.

[0075] In this embodiment, for beverages stored in a refrigerator, the turbidity and color values ​​of the beverages can be periodically measured. Then, based on the turbidity and color values, a match can be made with a target mapping table corresponding to the beverage category to determine the freshness of the beverage. This allows for the periodic detection of changes in beverage freshness caused by various factors during storage. Compared to static monitoring methods based on shelf life and storage duration in related technologies, this improves the accuracy of beverage freshness detection.

[0076] This disclosure provides another method for detecting the freshness of beverages, such as... Figure 5 As shown, the detection method includes: S501, the control device identifies the beverage category of the beverage to be tested.

[0077] S502, the control device determines the target lookup table corresponding to the beverage category.

[0078] S503, after the refrigerator door has been closed for a set period of time, the control device acquires at least one of the turbidity value and color value of the beverage to be tested in the placement position.

[0079] S504, the control device determines the freshness of the beverage based on a target lookup table, which corresponds to at least one of the turbidity value and color value of the beverage to be tested.

[0080] S505, the control device determines the target color corresponding to the freshness of the beverage.

[0081] S506, when the refrigerator door is opened, the control device controls the light unit to illuminate the beverage to be tested with light of the target color, or controls the beverage freshness display device to display the target color.

[0082] Specifically, after determining the freshness of the beverage to be tested, the light source illuminates the beverage with the target color, or the beverage freshness display device is controlled to display the target color. This intuitive visual feedback allows users to quickly understand the freshness of the beverage. For example, green light can indicate that the beverage is fresh, red light indicates that the beverage is not fresh, and yellow light indicates that the freshness of the beverage cannot be determined.

[0083] In this embodiment, after determining the beverage freshness corresponding to its turbidity and / or color values, the light source can illuminate the beverage to be tested with light of the target color, or the beverage freshness display device can be controlled to display the target color. In this way, users can quickly determine whether to drink the beverage simply by observing the color of the light source or the beverage freshness display device, improving the intuitiveness of understanding the beverage's freshness.

[0084] Combination Figure 6 As shown, in some embodiments, the control device 600 of the beverage freshness detection apparatus includes a processor 601 and a memory 602. Optionally, the device may further include a communication interface 603 and a bus 604. The processor 601, communication interface 603, and memory 602 can communicate with each other via the bus 604. The communication interface 603 can be used for information transmission. The processor 601 can call logical instructions in the memory 602 to execute the beverage freshness detection method of the above embodiments.

[0085] Furthermore, the logic instructions in the aforementioned memory 602 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.

[0086] The memory 602, as a computer-readable storage medium, can be used to store software programs and computer-executable programs, such as the program instructions / modules corresponding to the methods in the embodiments of this disclosure. The processor 601 executes functional applications and data processing by running the program instructions / modules stored in the memory 602, thereby implementing the beverage freshness detection method in the above embodiments.
