[0014] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0015] In the present invention, unless otherwise specified, directional words such as "upper, lower, left, right" are usually defined in terms of the directions of the drawings, and "inner and outer" refer to the inside and outside of the relevant parts. In addition, the terms "first", "second", "third", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection within a component. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] See also Figure 1-5 : In this embodiment, an automatic vehicle for automatically making, blending and selling coffee includes: an automatic making module, an automatic blending module, an automatic selling module, an automatic driving vehicle, a support frame, and a control system; The support frame is installed on the automatic driving vehicle and combined with the automatic driving vehicle. The support frame is mainly responsible for supporting and fixing various equipment to ensure the stability, safety and reliability of the equipment during the automatic driving process; the commonly used materials for the support frame include: stainless steel: has good strength, corrosion resistance and easy processing, and is an ideal material for the support frame; aluminum alloy: light weight, high strength, suitable for structural parts that require lighter weight and higher strength; composite materials: such as carbon fiber or glass fiber reinforced plastic, suitable for occasions with higher requirements for weight and strength; The support frame design should adopt a modular structure to facilitate later maintenance and equipment replacement; the modular design can allocate different equipment to different support modules, and the equipment layout can be adjusted as needed; at the same time, during the automatic driving process, the coffee car will face certain vibrations, so the support frame needs to be designed to be a structure that can effectively absorb vibrations, such as a spring shock absorber: add springs or rubber pads between the support frame and the equipment to reduce vibrations; hydraulic devices can also be used to further reduce vibrations and impacts.

[0018] In this implementation case, the automatic production module is the core part of the automatic driving coffee car, which is responsible for the automatic operation of the whole process from grinding, extraction, brewing, heating, and seasoning of coffee beans. It mainly includes: coffee bean storage bin, grinder, coffee extraction device, brewing device, bean grinder, heating device, and cooking pot; The coffee bean storage bin is used to store various types of coffee beans and ensure the freshness of the coffee beans. The bin is equipped with a fresh-keeping function, which can extend the service life of the coffee beans and can accommodate various different types of coffee beans. The current number of stored coffee beans is displayed to ensure that the system can promptly remind users to add coffee beans. When the number of coffee beans is lower than a preset threshold, the system will sound an alarm to remind users to add coffee beans. At the same time, the amount of coffee beans is automatically controlled according to the order requirements to ensure that the amount of beans required for each cup of coffee is accurate. The amount of coffee beans stored in the bin can also be adjusted according to the requirements of different types of coffee. The grinder grinds coffee beans into coffee powder suitable for extraction. The coarseness of the grinding directly affects the flavor of the coffee. The grinding coarseness can be adjusted to meet the needs of different types of coffee (such as espresso, Italian espresso, etc.). The electric system is used to control the grinding accuracy and speed to ensure the consistency of grinding. During the grinding process, the dust-proof device can prevent the leakage of coffee powder and keep the equipment clean. The low-noise design ensures that no excessive noise is generated during the grinding process to affect the user experience. The coffee extraction device combines ground coffee powder with water and extracts the essence of coffee through high pressure. Hot water is passed through the coffee powder through a high pressure system to extract the essence of coffee. The system can accurately control the pressure and time of extraction. During the extraction process, the temperature control system ensures that the water temperature is kept in the optimal range (90°C-95°C). Too high or too low a temperature may affect the flavor of the coffee. The coffee grounds are filtered out to ensure that the coffee liquid is clear and free of impurities. The speed of water flowing through the coffee powder can also be adjusted to ensure the extraction effect. The system also supports single-cup or double-cup operation to meet the needs of different users. The brewing device can accurately control the ratio of coffee powder to water, temperature and other factors according to user needs to ensure that the taste of the coffee brewed each time is consistent. The intelligent water flow control system can accurately control the amount of water and flow rate for each brewing to ensure the stability of the concentration and flavor of the coffee. The temperature control system can accurately control the hot water temperature according to the set temperature range (such as 80-95°C) to avoid excessively high or low water temperature affecting coffee extraction. After each brewing, the automatic cleaning device starts the automatic cleaning system to remove coffee residues, keep the equipment clean and prevent cross contamination. The bean grinder further optimizes the particle size of the coffee powder to make it more uniform and improve the extraction effect. The temperature control system ensures that the temperature during the grinding process is not too high to avoid overheating of the coffee beans and affect the flavor. The time control system avoids over-grinding through precise time control to ensure the uniformity of the particles. A mute device is provided during the grinding process to reduce noise pollution and improve user experience. The boiling pot heats the extracted coffee stock to an appropriate temperature to keep the coffee hot or to make coffee with a specific flavor (such as espresso, latte, etc.); the temperature control system ensures that the temperature of the coffee stock is kept within an ideal range during the heating process to avoid loss of coffee flavor due to overheating; the heating device (such as an electric heater) is used to quickly heat up the coffee to ensure the efficiency of coffee making; The steam generator provides high-pressure steam for steaming milk and heating coffee liquid, especially when making latte, cappuccino and other coffee; the high-pressure steam output can generate sufficient steam pressure to quickly heat or make milk foam; the temperature control system ensures that the steam temperature is appropriate through precise temperature control to avoid overheating of the milk foam or failure to whip successfully.

According to the needs, these storage tanks are usually constant temperature tanks to ensure that the milk is kept within the optimal temperature range for subsequent mixing and milk foaming. The storage tanks are generally made of stainless steel or food-grade materials, with smooth inner walls, easy to clean and avoid milk contamination. The milk storage tank is equipped with a temperature control system, which monitors the milk temperature in real time through a temperature sensor. The control system can automatically adjust the heater or cooling equipment to keep the milk within a suitable temperature range (usually between 4°C and 60°C); the system delivers the milk to the mixing area in proportion through a precise liquid distribution device (such as a metering pump or a solenoid valve), and adjusts the flow of milk through the control system to ensure that the ideal amount of milk is mixed each time. The milk storage tank is usually equipped with a liquid level sensor to monitor the storage amount of milk; when the milk stock is insufficient, the system will issue a warning to prompt manual addition or replenishment; The milk frothing device is equipped with a milk frothing generator, which is used to heat the milk and make fine milk froth. The milk frothing generator is usually composed of one or more electric stirring devices (such as a high-speed rotating stirring head) and a steam nozzle. During the milk frothing process, high-temperature steam is injected into the milk through the steam system to expand it and produce rich milk froth. The steam system includes a steam generator, a nozzle and a temperature control device to ensure that the temperature and flow of the steam meet the milk froth requirements; When the user selects a drink containing milk foam, the control system first instructs the milk foam device to start, the steam generator heats the water into steam, and transmits the steam to the milk foam generator through high pressure to stimulate the bubbles of milk; The system monitors the milk foam production process through temperature sensors, pressure sensors, etc. to ensure that the quality of the milk foam meets the set standards (such as the fineness and volume of the milk foam); The mixing device is provided with an automatic stirring device for uniformly mixing raw materials such as coffee, milk, and syrup, which is usually accomplished by an electrically driven stirrer (such as a rotating stirring blade or a mechanical arm). The automatic stirring device is often arranged in a mixing area. The container may be open or closed, with a smooth inner wall to prevent accumulation of residues. The container is designed to ensure uniform stirring without dead corners. The system will adjust the stirring intensity and time according to the type of beverage (such as latte, cappuccino, etc.) to ensure that the raw materials are fully mixed and obtain an ideal taste.
