Description

Technical Field

[0001] The invention relates to a bean box of a coffee machine, in particular to a bean discharging mechanism of a bean box of an anti-jamming coffee machine. Background Art

[0002] Coffee machine is an electrical device used for making coffee, generally divided into semi-automatic and fully automatic. Among them, the semi-automatic coffee machine is a traditional Italian coffee machine, which is operated by manual grinding, pressing, loading, brewing, and manual removal of residues; among them, the fully automatic coffee machine realizes automatic control of the whole process of brewing coffee, such as preheating, cleaning, grinding, pressing, brewing, and draining, and brews coffee according to scientific data and procedures. It is equipped with a complete protection system, which is convenient to use and can get coffee with just one click. The grinding mechanism of the coffee machine is a kind of grinding tool that cuts and grinds coffee beans into coffee powder when the motor drives the mechanical cutter to rotate rapidly. However, the grinding mechanism of the existing coffee machine usually needs to put a certain amount of coffee beans into the bean box when grinding coffee powder, and grind it through the grinder. Therefore, in most cases, it is difficult to control the amount of coffee beans, and most users are non-professionals, and cannot quantitatively grind the amount of coffee powder they need. After taking out the bean box, there will be residual coffee beans on the grinding disc, which will affect the next time that coffee beans of different flavors are mixed together, affecting the taste quality of coffee. To this end, some existing automatic coffee machines that automatically unload, grind and discharge beans are equipped with an anti-stuck structure at the bean box unloading mechanism, such as the application number 202420089692.0 disclosed in the Chinese patent literature, the authorization announcement date 2024.09.17, and the utility model name "Anti-stuck bean structure and bean grinding device"; it is mainly achieved by setting a horizontal feeding screw below the bean unloading port in the bean box. The above-mentioned products and similar products are still prone to bean jams during the bean unloading process, and are prone to splashing out when entering the grinder. The bean unloading components are not well fixed and lack of in-place detection. Summary of the invention

The gear piece of the anti-bean jamming gear in the above-mentioned arched cavity is inserted into the gap between the bean-pushing pieces of the lower bean gear or is located above the gap. The anti-bean jamming gear is driven to rotate by the rotation of the lower bean gear, or the anti-bean jamming gear is driven to rotate by the rotation of the coffee beans stuck in the lower bean gear. A micro motor can also be arranged at the rear of the anti-bean jamming gear to realize its rotation. The cylindrical sleeve at the bottom of the above-mentioned lower bean box placement frame is convenient for inserting into the powder inlet channel of the grinding bean assembly, and can also be replaced or omitted as needed.

[0042] When in use, first put the coffee beans into the bean box. After the machine starts working, the bean discharge gear rotates clockwise and drives the coffee beans in the bean box into the arched cavity containing the anti-bean jamming gear. If the coffee beans do not accumulate in the arched cavity, they will fall out of the bean discharge opening of the lower cover of the bean box; if accumulation occurs, the anti-bean jamming gear will move clockwise under the thrust of the accumulated coffee beans, and bring the accumulated coffee beans into the gear leaves of the anti-bean jamming gear for rotation, thereby reducing the amount of accumulation during the bean discharge process.

This is an improved and iterative mechanism for the automatic bean feeding technology of a coffee machine bean box. When the bean feeding gear in the coffee machine bean box drives the coffee beans to be fed, it is easy for the beans to get stuck at the bean feeding port, causing a bad experience for the user. Based on this background, the existing mechanism is improved to solve the bean jam problem. The main features of the mechanism are as follows: 1. The anti-bean jam gear transmission is used to drive the accumulated coffee beans to move and reduce accumulation; 2. The anti-bean jam gear is equipped with damping oil and a silicone sealing ring for interference fit to prevent the coffee beans from leaking out when the bean box is picked up.
