Description

Technical Field

[0001] This utility model belongs to the field of weighing equipment, and in particular relates to an intelligent scale. Background Technology

[0002] Currently, canteens and catering establishments typically use smart checkout scales instead of traditional cashier scales, avoiding the tedious operations of manually selecting dishes and binding price information. Existing smart checkout scales usually consist of a weighing module and an RFID sensing module. Users need to use a special tray with a built-in RFID chip for identification and binding, and the system calculates the charge based on the weight of the food taken. However, this existing technology has the following main drawbacks: RFID chip embedding in the tray leads to high costs, and the chip cannot be sterilized at high temperatures, posing a hygiene risk; the equipment generally only has a single weighing module, with one scale corresponding to only one dish, leading to inconsistencies in food quality. The existing smart scales require multiple devices, which are costly and space-consuming. In addition, the weighing and sensing modules of the existing equipment are usually separate structures, resulting in poor overall integration and inconvenience in installation and relocation. Especially in terms of heat preservation, the existing smart scales do not have heating functions at all. In autumn and winter or when the dining time is long, the temperature of the food will drop to room temperature quickly, which will seriously affect the taste and quality of the food. Although some canteens use external heating equipment to heat the food, this separate solution not only takes up extra space and increases equipment costs, but also has low thermal efficiency, inaccurate temperature control, and cannot be organically linked with the weighing and billing system. Utility Model Content

[0003] The purpose of this utility model is to provide a smart scale to solve the technical problems of commonly used smart settlement scales, such as the high cost caused by embedding RFID chips in the tray, the inability of the chips to be sterilized at high temperatures, which poses a hygiene risk, the fact that one scale can only correspond to one dish, which requires multiple devices in the canteen, resulting in high cost and large space occupation, the fact that the weighing, sensing and other functional modules are usually separate structures, resulting in poor overall integrity, inconvenient installation and relocation, and the lack of heating function, which makes it difficult to keep the dishes warm.

[0004] To achieve the above objectives, the specific technical solution of this utility model for an intelligent scale is as follows: A smart scale includes a main body; a column is provided on one side of the main body; a weighing module is provided on the main body; a heat preservation module is provided on the weighing module; a drool dust cover is provided on the column opposite to the heat preservation module and the weighing module; a camera module is provided on the top of the column opposite to the main body; a barcode scanning module is provided on one side of the main body; supplementary lights are provided on both sides of the barcode scanning module on the main body; a display screen module is provided on the upper side of the barcode scanning module on the main body; and a warning light module is provided on one side of the column; wherein the weighing module, heat preservation module, camera module, barcode scanning module, display screen module, supplementary lights, and warning light module are all electrically connected to a control unit provided in the main body.

[0005] Furthermore, the saliva dust cover is made of transparent material.

[0006] Furthermore, there are two weighing modules, and each of them is equipped with a corresponding heat preservation module.

[0007] Furthermore, a warm light is installed on the outside of the camera module on the pillar.

[0008] Furthermore, a heat preservation mode switch for controlling the start and stop of the heat preservation module is provided on one side of the main body.

[0009] Furthermore, the main body, column, saliva dust cover, weighing module, heat preservation module, camera module, barcode scanning module, display module, warm light, supplementary light and warning light module are integrated into one structure.

[0010] This utility model of a smart scale has the following advantages: By integrating the main body, column, weighing module, insulation module, saliva dust cover, camera module, barcode scanning module, display module, and warning light module into a single structure, it avoids the defects of existing technologies where equipment is scattered and has limited functionality. This structure allows a single device to perform functions such as identification, weighing and pricing, insulation, protection, and payment reminders, greatly simplifying the layout of canteen stalls, saving equipment installation space, and facilitating installation and relocation. Furthermore, by using a barcode scanning module in conjunction with ordinary trays printed with barcodes or QR codes, it replaces the currently commonly used RFID chip sensing mode, reducing... With reduced investment costs, the cost of trays is significantly lowered, and high-temperature cleaning and disinfection before use greatly improves food hygiene and safety. By incorporating two independent weighing modules on the main unit, one device can simultaneously weigh two types of dishes, increasing the efficiency of weighing and pricing while reducing the investment cost and space occupation of canteen equipment. The integrated heat preservation module on the weighing module, along with a separately set heat preservation mode switch, provides controllable heating and heat preservation capabilities, effectively maintaining the temperature of dishes during weighing and pricing to prevent them from cooling down too quickly, ensuring optimal taste and quality without the need for additional heat preservation equipment, thus reducing investment.

[0012] To better understand the purpose, structure, and function of this utility model, the following description of an intelligent scale, in conjunction with the accompanying drawings, will be provided in further detail.

[0013] like Figure 1-3 As shown, this utility model discloses an intelligent scale, including a main body 101; a column 1 is provided on one side of the main body 101; a weighing module 2 is provided on the main body 101; a heat preservation module 3 is provided on the weighing module 2; a drool dust cover 4 is provided on the column 1 relative to the heat preservation module 3 and the weighing module 2; a camera module 5 is provided on the top of the column 1 relative to the side of the main body 101; a barcode scanning sensor module 6 is provided on one side of the main body 101; supplementary lights 7 are provided on both sides of the barcode scanning sensor module 6 on the main body 101; a display screen module 8 is provided on the upper side of the barcode scanning sensor module 6 on the main body 101; and a warning light module 9 is provided on one side of the column 1. The weighing module 2, heat preservation module 3, camera module 5, barcode scanning sensor module 6, display screen module 8, supplementary lights 7, and warning light module 9 are all electrically connected to a control unit located within the main body 101.

[0014] Combination Figure 1-3 As shown, when using this equipment, canteen staff place the pot containing the food onto the surface of the heat preservation module 3 on the main body 101. The heat preservation module 3 can be made of black mirror glass and can achieve weighing and heating functions. The rear camera module 5 captures images of the food, identifies the food information, and displays the food name, price, nutritional information, etc. on the display module 8. Consumers place the tray with the barcode or QR code printed on it in front of the main body 101. The barcode scanning sensor module 6 on one side of the main body 101 scans the barcode or QR code on the tray under the auxiliary lighting of the supplementary lights 7 on both sides to obtain the tray information. At the same time, the camera module 5 on the column 1 reads the consumer's facial information to obtain the user ID and binds the user with the tray information. Then the customer picks up the food.

[0015] Consumers take food from the pot on the heat preservation module 3 and place it on their tray. At this time, the weighing module 2 located below the heat preservation module 3 detects the decrease in weight and transmits the weight change signal to the control unit. The control unit calculates the weight and price of the food in real time and dynamically updates the display on the display module 8. The entire food retrieval process is carried out under the protection of the saliva dust cover 4 on the column 1, ensuring food hygiene. When the consumer finishes taking the food and removes the tray from the sensing area of ​​the barcode scanning module 6, the sensing module can no longer detect the tray signal. The control unit then generates the final order based on the total weight reduction during this period and automatically deducts the payment from the corresponding user's account. During the entire process, if there is insufficient account balance, the warning light module 9 located on one side of the column 1 will emit a light signal to indicate the situation.

[0016] The saliva dust cover 4 is made of transparent material. By installing the transparent saliva dust cover 4 on the column 1, it can effectively prevent droplets and dust from contaminating the food when consumers are observing or taking the food, thus improving dining safety.

[0017] There are two weighing modules 2, and each of them is equipped with a corresponding heat preservation module 3. By setting two independent weighing modules 2 on the main body 101, one device can simultaneously carry and measure two kinds of dishes, increasing the efficiency of weighing and pricing, and reducing the investment cost and space occupation of canteen equipment.

[0018] A warm light 10 is installed on the outside of the camera module 5 on the column 1. The warm light 10 provides optimized lighting for food display and ensures the success rate of consumer face recognition, thereby enhancing the visual appeal of the food, making the food more colorful and aesthetically pleasing, and improving the user experience.

[0019] like Figure 3 As shown, a heat preservation mode switch 11 for controlling the start and stop of the heat preservation module 3 is provided on one side of the main body 101. By integrating the heat preservation module 3 on the weighing module 2, and with the independently set heat preservation mode switch 11, this device has controllable heating and heat preservation capabilities, which can effectively maintain the temperature of the dishes during weighing and pricing, prevent them from cooling down too quickly, and ensure the best taste and quality of the dishes. There is no need to purchase additional heat preservation equipment, thus reducing investment.

[0020] like Figure 1-3As shown, the main body 101, column 1, saliva dust cover 4, weighing module 2, heat preservation module 3, camera module 5, barcode scanning module 6, display screen module 8, warm light 10, supplementary light 7, and warning light module 9 are integrated into one structure, avoiding the defects of scattered equipment and single function in the existing technology. This structure enables a single device to perform functions such as identification, weighing and pricing, heat preservation, protection, and payment reminder, which greatly simplifies the layout of canteen stalls, saves equipment installation space, and facilitates installation and relocation.
