Description

Technical Field

[0001] The utility model relates to a coffee machine accessory, in particular to an automatic coffee powder falling mechanism for a coffee grinder. Background Art

[0002] Coffee is a beverage made from roasted and ground coffee beans. As one of the world's three major beverages, it is popular around the world together with cocoa and tea. With the continuous improvement of living standards, coffee has gradually become an indispensable drink in people's daily lives. In order to adapt to the development of society and the needs of users for convenience, modern coffee machines can already achieve full-process control of a series of coffee brewing processes such as grinding, tamping, powder loading, brewing, and residue removal.

[0003] In the design of traditional coffee machines, after the coffee grinding process is completed, the coffee powder usually directly falls from the coffee grinder to the next process. Due to the lack of intermediate control in this direct falling method, every time a user makes coffee, they must manually weigh and add the corresponding amount of coffee powder. This not only takes a long time and is troublesome to operate, but also due to the error of manual weighing, it is difficult to ensure the consistency of the coffee concentration and taste for each brewing.

[0004] To solve this problem, some manufacturers have added an opening and closing mechanism between the coffee grinding process and the next process to temporarily block the falling of coffee powder, and users can start the opening and closing mechanism to perform the powder falling operation when needed. This improvement enables users not to add coffee powder every time, making the operation more flexible. However, these existing opening and closing mechanisms are usually complex in design and have many components, resulting in a high manufacturing cost. At the same time, the complex structure is also prone to failures, increasing the maintenance difficulty of the equipment. Therefore, it is necessary to make further improvements to it. Summary of the Utility Model

[0021] The following further specifically describes the present utility model with reference to the accompanying drawings. An automatic coffee powder falling mechanism of a coffee grinder includes a base 1, on which a powder falling port 11 is provided. Correspondingly, a powder falling pipe 2 is installed above the powder falling port 11, and the top of the powder falling pipe 2 is connected to the coffee grinder. The coffee powder ground by the coffee grinder falls downward from the powder falling port 11 through the powder falling pipe 2 to achieve automatic powder falling. A valve plate 3 is also hingedly installed on the base 1. A valve port 31 is provided on the valve plate 3. The valve plate 3 swings around the hinge point under the drive of a power mechanism, so that the valve port 31 on the valve plate 3 is docked with or separated from the outlet of the powder falling pipe 2, realizing the opening and closing of the powder falling pipe 2.

[0022] In one embodiment: a receiving area 13 is concavely provided on the upper end surface of the base 1, and the valve plate 3 is swingably hingedly installed in the receiving area 13, and the powder falling port 11 is provided in the receiving area 13.

[0023] In one embodiment: the power mechanism is a driving gear 41 driven by a reduction motor 4. Correspondingly, a driven gear 42 is connected to the valve plate 3 and meshes with the driving gear 41. The reduction motor 4 drives the valve plate 3 to move through the meshing of the driving gear 41 and the driven gear 42.

[0024] In one embodiment: the driven gear 42 is integrally formed with the valve plate 3.

[0025] In one embodiment: the powder falling pipe 2 is installed on the base 1 through a bracket 21, and the powder falling pipe 2 and the base 1 clamp the valve plate 3 therebetween.

[0026] In one embodiment: position switches 12 are provided on both sides of the receiving area 13. When the valve plate 3 runs to a set position, it touches the position switches 12 to generate an electric control signal.

[0027] In one embodiment: the power mechanism is a solenoid valve installed on the base 1, and the valve rod of the solenoid valve is hinged to the valve plate 3.

[0028] Working principle: When the coffee grinder grinds coffee beans, the ground coffee powder enters the interior of the base through the powder dropping tube located on the base. The powder dropping tube is connected above the base, and the coffee powder ground by the grinder flows in from the upper part through the powder dropping tube and is ready to fall into the coffee machine below.

[0029] Among them, a valve plate is hingedly installed on the base, and a valve port corresponding to the outlet of the powder dropping tube is provided on the valve plate. When the powder dropping operation is not started, the valve plate is in a closed state, that is, the valve port is not docked with the outlet of the powder dropping tube, thereby blocking the fall of the coffee powder.

[0030] Furthermore, when the powder dropping operation is required, the power mechanism drives the valve plate to swing. The power mechanism can be a driving gear driven by a reduction motor, which meshes with the driven gear on the valve plate. Through gear transmission, the valve plate is driven to swing around its hinge point, so that the valve port is docked with the outlet of the powder dropping tube. At this time, the ground coffee powder smoothly falls into the coffee machine below through the powder dropping tube and the docked valve port, completing the powder dropping process.

[0031] In another implementation, the power mechanism can be driven by an electromagnetic valve. The valve rod of the electromagnetic valve is directly hingedly connected to the valve plate. The action of the electromagnetic valve drives the swing of the valve plate to realize the opening and closing control of the outlet of the powder dropping tube. The driving method of the electromagnetic valve is more concise and has a fast response speed, which is suitable for application occasions that require frequent control.

[0032] Furthermore: Position switches can be set on both sides of the accommodation area of the base. When the valve plate swings to a predetermined position, it touches the position switch and generates an electric control signal to feedback the current position of the valve plate. This design ensures that the valve plate can accurately stop at the open or closed position, preventing inaccurate powder dropping or abnormal closing of the valve plate caused by position deviation.

[0033] Compared with the traditional technology, in this case, through the precise opening and closing control of the valve plate, the present invention can effectively control the amount of coffee powder put in, realize the accurate powder dropping of coffee powder each time, and ensure the consistency of the concentration and taste of each cup of coffee. This precise control can greatly improve the user experience.

[0034] In addition, the present invention adopts a simple mechanical structure, such as a hinged valve plate and a gear transmission device, reducing the use of complex parts. Compared with the existing automatic powder dropping mechanisms on the market, the structure of the present invention is simpler, the manufacturing cost is lower, and it is easy to mass produce.

[0035] To sum up, through a simple and effective design, the present invention provides an efficient and reliable automatic powder dropping mechanism for a coffee grinder, which not only improves the automation degree of the coffee machine, but also significantly improves the user experience, so it can be widely promoted and used.

[0036] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
