Description

Technical Field

[0001] This utility model relates to a coffee machine, specifically a fully automatic coffee machine powder dispensing mechanism. Background Technology

[0002] As living standards improve, coffee has become an increasingly popular beverage. Freshly brewed coffee, made by instantly grinding coffee beans, produces a pure and delicious taste. Furthermore, by changing the type of coffee beans, different flavors can be achieved. Currently, automatic coffee machines, which quickly complete grinding and brewing operations, have become the preferred equipment for consumers.

[0003] However, existing coffee machines often have relatively simple internal coffee dispensing channels, typically using straight or curved tubes to guide the ground coffee into the brewing basket. Due to the narrowness of the dispensing channel and its proximity to the water supply, moisture from the water supply easily seeps into the dispensing channel, causing coffee grounds to accumulate on the channel walls. Over time, if the accumulated coffee grounds are not cleaned promptly, they will gradually form a thick layer. Once this dust adheres, it is difficult to remove completely using conventional cleaning methods. This not only affects the coffee dispensing speed but may also cause the coffee machine to clog and malfunction. Furthermore, the clogged coffee grounds may even mold, affecting the quality of the coffee and endangering the user's health. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a fully automatic coffee machine powder dispensing mechanism that is simple in structure, low in manufacturing cost, has a water outlet channel inside the powder outlet channel to effectively avoid clogging, reduce cleaning difficulty, improve the convenience of cleaning the coffee machine, and provides uniform powder dispensing and a long service life.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings. A fully automatic coffee machine powder dispensing mechanism includes a main body 1, a powder outlet channel 2 is provided inside the main body 1, the top of the powder outlet channel 2 is connected to the grinding mechanism, and the bottom of the powder outlet channel 2 is connected to the brewing basket 3;

[0021] The powder outlet channel 2 is also connected to a water outlet channel 4. The water outlet channel 4 is obliquely connected to the powder outlet channel 2. The water outlet of the water outlet channel 4 is located on the side wall of the powder outlet channel 2. The brewing water enters the powder outlet channel 2 through the water outlet channel 4 and rinses the inner wall of the powder outlet channel 2.

[0022] The included angle between the water outlet channel 4 and the powder outlet channel 2 is set to 35° to 65°.

[0023] The intersection of the water outlet 4 and the powder outlet 2 is located at the bottom of the powder outlet 2, about 1 / 3 of the way from the outlet of the powder outlet 2.

[0024] The water outlet 4 is located inside the water outlet pipe, which is connected to the water boiler via a silicone tube 5.

[0025] A sealing piston 6 is also installed inside the powder outlet channel 2. A piston rod 61 extends upward from the top of the powder outlet channel 2. The piston rod 61 is connected to a power mechanism, which drives the piston rod 61 to slide up and down inside the powder outlet channel 2.

[0026] The power mechanism is a slider driven by a geared motor. The slider slides outside the guide rod mounted on the main body 1. The geared motor is connected to an eccentric wheel and is connected to the slider. The piston rod 61 is connected to the slider.

[0027] A sealing ring 7 is fitted on the cylindrical surface of the piston rod 61, and the sealing ring 7 seals the gap between the sealing piston 6 and the powder outlet channel 2.

[0028] Working principle: When the coffee machine starts working, the grinding mechanism first grinds the coffee beans into powder, which then enters the brewing basket through the powder outlet. To ensure that the coffee powder is accurately and smoothly introduced into the brewing basket, the top of the powder outlet connects to the grinding mechanism, and the bottom connects to the brewing basket.

[0029] Unlike traditional coffee machines with a separate water outlet, this machine's water outlet is angled and connected to the powder outlet. The outlet of this water outlet is located on the side wall of the powder outlet and is connected to it. The brewing water enters the powder outlet at an angle through this water outlet, rinsing the inner wall of the powder outlet. The flowing brewing water not only helps to remove coffee powder residue from the inner wall of the powder outlet, but also prevents coffee powder from accumulating in the powder outlet over a long period of time, fundamentally preventing the problem of clogging caused by the accumulation of coffee powder.

[0030] Furthermore, the angle between the water outlet and the powder outlet is set to 35° to 65°, and the intersection of the water outlet and the powder outlet is located at the bottom of the powder outlet, near the 1 / 3 point of the powder outlet outlet. Within this angle range, the water flow can increase its impact intensity. At the same time, under the action of gravity, it can effectively ensure that the water in the water channel can be discharged smoothly, and it can also rinse the powder outlet more evenly, thus improving the cleaning effect.

[0031] Furthermore, a sealing piston is installed within the powder outlet channel. A piston rod extends upwards from the top of the outlet channel, connecting to a power mechanism. This piston rod drives the sealing piston to slide vertically within the outlet channel, opening or closing it and ensuring a uniform and stable delivery of coffee powder to the brewing basket. To ensure a tight seal within the outlet channel, a sealing ring is fitted onto the piston's cylindrical surface. This ring seals the gap between the piston and the air outlet, effectively preventing water vapor from flowing back into the outlet channel and into the grinding mechanism. The power mechanism is a slider driven by a geared motor. The slider slides outside a guide rod mounted on the main body. An eccentric wheel connected to the geared motor connects to the slider, driving the sealing piston to move smoothly up and down within the outlet channel, thus opening and closing the powder inlet. When closed, the brewing water entering the outlet channel cleans the piston's end face, keeping it clean and hygienic.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
