DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 A coffee machine bean bin mechanism comprises a shell 1, a collar 5 is fixedly connected to the top of the shell 1, a bean box 6 is plugged into the inner wall of the collar 5, the bottom of the bean box 6 movably penetrates the shell 1, and a first feeding hole 8 is provided at the bottom of the bean box 6, a base 10 is rotatably engaged with the outer arm surface of the bottom of the bean box 6, a rotating piece 11 is rotatably connected to the inner wall of the base 10, a convex plate 14 is fixedly connected to the side wall of the rotating piece 11, and a bone groove 15 is provided on the inner wall of the base 10 near the rotating piece 11, and the inner wall of the bone groove 15 is movably engaged with the outer wall of the convex plate 14.

[0024] The fixed connection between the shell 1 and the collar 5 allows the collar 5 to stably provide long-lasting support for the bean box 6. The first discharge hole 8 opened in the bean box 6 is conducive to the direct discharge and barrier closure of coffee beans. The rotational connection between the rotating piece 11 and the base 10 allows the base 10 to provide a platform for rotational support for the rotating piece 11. The fixed connection between the convex plate 14 and the rotating piece 11 is conducive to helping the convex plate 14 to be flexibly engaged with the bone groove 15, so that the rotating piece 11 and the bean box 6 can be flexibly opened and closed, which is conducive to controlling the discharge amount of coffee beans.

[0025] The rotating plate 11 is provided with a second material discharge hole 13, the notch of the second material discharge hole 13 is movably matched with the notch of the first material discharge hole 8, the top of the protruding plate 14 is movably engaged with a locking plate 16, and the side of the locking plate 16 is fixedly connected to the side wall of the bean box 6.

[0026] The first feeding hole 8 and the second feeding hole 13 are movably matched, and the coffee beans 3 are stabilized through the alignment and fit of the feeding holes, which reflects the practical effect of the overall device. The clamping cooperation between the positioning plate 16 and the convex plate 14 makes the openings of the bean box 6 and the rotating piece 11 overlap and communicate when they rotate to a certain angle, so that the coffee beans can be continuously fed; or the bean box 6 and the rotating piece 11 are misaligned, and the coffee beans cannot be stably fed through the first feeding hole 8 and the second feeding hole 13, thereby realizing the control of the amount of coffee beans.

[0027] A plug hole 9 is provided at the center of the bean box 6, and an umbrella cover 7 is plugged and connected to the inner wall of the plug hole 9.

[0028] The plug connection between the umbrella cover 7 and the socket 9 ensures that the top of the coffee beans is closed after being ground by the coffee machine, which can ensure that the aroma of the coffee beans is not easy to overflow and the taste of the coffee can be retained.

[0029] The bottom of the base 10 is connected to a discharge piece 12 , and the bottom of the side of the housing 1 is fixedly connected to a protection frame 4 , and the inner wall of the protection frame 4 is fitted with the discharge piece 12 .

[0030] The connection between the discharge piece 12 and the base 10 allows the coffee liquid to flow out in time, and the fitting arrangement between the protective frame 4 and the discharge piece 12 can prevent the boiling coffee liquid from splashing.

[0031] The inner cavity surface of the housing 1 is fixedly connected with a connecting frame 3 , and the side surface of the connecting frame 3 is movably connected with a micro motor 2 , and the output end of the micro motor 2 is drivingly connected with a discharging member 12 .

[0032] The movable engagement between the connecting frame 2 and the micro motor 2 allows the micro motor 2 to remain stable during operation, and the transmission connection between the micro motor 2 and the discharge member 12 further helps the power at the output end of the micro motor 2 to be transmitted.

[0033] There are two first material discharge holes 8 , and the two first material discharge holes 8 are symmetrically arranged in the bottom inner cavity of the bean box 6 .

[0034] The first feeding hole 8 is symmetrically arranged in the inner cavity at the bottom of the bean box 6, so that the coffee beans can be fed faster, thereby improving the grinding efficiency of the coffee machine.

[0035] The convex plate 14 and the locking plate 16 have the same shape.

[0036] The convex plate 14 and the locking plate 16 are arranged in the same shape, so that when the coffee machine needs maintenance and cleaning, the convex plate 14, the locking plate 16 and the bone groove 15 are aligned and locked, which helps to disassemble and remove the rotating piece 11 and the bean box 6 as a whole, facilitates the timely cleaning of the rotating piece 11 and the bean box 6, and increases the service life.

[0037] Working method: During operation, coffee beans are poured from the bean box 6 into the coffee machine. When the coffee beans pass through the first discharge hole 8, the rotating plate 11 is rotated to align the second discharge hole 13 opened on the rotating plate 11 with the first discharge hole 8 (at this time, the positioning plate 16 arranged on the side of the bean box 6 and the convex plate 14 arranged on the side of the rotating plate 11 are misaligned). Then, the misalignment of the positioning plate 16 and the convex plate 14 will cause the bean box 6 and the rotating plate 11 to be difficult to separate. Then, the coffee beans are directly gathered in the inner cavity of the base 10. Then, the discharge piece 12 is assembled and connected with the base 10, the connecting frame 3 is plugged and arranged in the inner cavity of the shell 1, and the micro motor 2 is connected to the discharge piece 12 for transmission. The discharging aid 12 grinds the coffee beans to finally form coffee liquid, and the protective frame 4 helps the coffee liquid to fall into the cup evenly, avoiding splashing of the coffee liquid; when the coffee machine is blocked by powder or the bean grinding device needs maintenance and cleaning, the rotating piece 11 is rotated at this time to align the convex plate 14 with the clamping plate 16 fixed on the side of the bean box 6, and further the convex plate 14 is aligned with the bone groove 15 opened inside the base 10, so that the rotating piece 11 and the bean box 6 can be lifted and removed as a whole, which is convenient for quick cleaning and maintenance. The device improves the problem that the bottom opening cannot be closed when the bean box 6 is removed, plays an important role in preventing coffee beans from spilling, and is suitable for application.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
