Description

Technical Field

[0001] This text relates to home appliance technology, especially a coffee machine and its hopper. Background Art

[0002] As an important component of an automatic coffee machine, the bean hopper is used to hold coffee beans. It is necessary to ensure that the coffee beans stored therein can be effectively introduced into the grinder when the coffee machine is working, and it is also necessary to maintain airtightness to preserve the flavor of the coffee beans when the coffee machine is not working.

[0003] The bean hopper can be detached from the body of the automatic coffee machine. To prevent the coffee beans in the bean hopper from spilling onto the ground through the bean dropping channel when the bean hopper is detached, a push-pull baffle is provided on the bean hopper to open and close the bean dropping channel. Pushing the push-pull baffle inward can close the bean dropping channel, and pulling the push-pull baffle outward can open the bean dropping channel. However, if there are remaining beans in the bean dropping channel, these remaining beans will jam the push-pull baffle, resulting in the inability to close the bean dropping channel. At the same time, the clearance between the push-pull baffle and the bean hopper is too large to effectively seal the bean hopper, and the coffee beans in the bean hopper are prone to deterioration. Summary of the Invention

[0004] The technical problem to be solved by this application is the technical problem that the bean hopper of the existing coffee machine cannot be effectively sealed.

[0005] This application provides a hopper, which includes:

[0006] A storage bin, provided with a storage cavity and a discharge channel extending downward from the storage cavity; and

[0007] An opening and closing member, arranged in the discharge channel and rotatably connected to the discharge channel;

[0008] Wherein, the opening and closing member can rotate to an open position where the discharge channel is opened and a closed position where the discharge channel is closed and is in interference fit with the discharge channel.

[0009] In a schematic embodiment, the opening and closing member is configured in a flat plate shape, and the rotation axis of the opening and closing member is parallel to the opening and closing member and perpendicular to the extending direction of the discharge channel.

[0010] In a schematic embodiment, shaft holes are provided on both opposite side walls of the discharge channel;

[0011] The hopper further includes a rotating shaft, parallel to and connected to the opening and closing member, and both ends of which respectively extend into the two shaft holes.

[0012] In a schematic embodiment, when the opening and closing member is in the closed position, the rotating shaft is located on the side of the opening and closing member facing away from the storage cavity.

[0013] In a schematic embodiment, the storage bin further includes a blocking portion disposed on the inner sidewall of the storage cavity near the discharge passage;

[0014] The blocking portion is provided with a guiding concave surface facing the discharge passage, and when the opening and closing member reciprocally rotates between the open position and the closed position, the edge of the opening and closing member close to the blocking portion slides along the guiding concave surface.

[0015] In a schematic embodiment, the cross-section of the discharge passage is circular, the opening and closing member is in the shape of a circular plate, and the guiding concave surface is a spherical surface.

[0016] In a schematic embodiment, the bin further includes a lever, one end of the lever is connected to the opening and closing member, and the other end extends into the storage cavity;

[0017] When the opening and closing member rotates to the closed position, the lever abuts against the side of the blocking portion facing away from the discharge passage, and when the opening and closing member rotates to the open position, the lever abuts against the inner sidewall of the discharge passage opposite to the blocking portion.

[0018] In a schematic embodiment, the lever includes:

[0019] A first straight rod, one end of which is connected to the opening and closing member and is perpendicular to the opening and closing member; and

[0020] A second straight rod, one end of which is connected to the end of the first straight rod facing away from the opening and closing member and is perpendicular to the rotation axis and the first straight rod;

[0021] Wherein, when the opening and closing member rotates to the closed position, the second straight rod abuts against the side of the blocking portion facing away from the discharge passage, and when the opening and closing member rotates to the open position, the second straight rod abuts against the inner sidewall of the discharge passage opposite to the blocking portion.

[0022] In a schematic embodiment, the bin further includes a lever disposed outside the storage bin, and the lever is connected to one end of the rotating shaft.

[0023] In a schematic embodiment, the opening and closing member includes:

[0024] A body, configured in the shape of a plate, and rotatably connected to the discharge passage; and

[0025] A first sealing ring, clamped on the side surface of the body;

[0026] Wherein, when the opening and closing member rotates to the closed position, the first sealing ring is clamped between the body and the discharge passage.

[0027] In a schematic embodiment, an annular groove surrounding the body is provided on the side surface of the body;

[0028] The inner edge of the first sealing ring is embedded in the annular groove.

[0029] This application also proposes a coffee machine, which includes the hopper as described above.

[0030] After the hopper is installed on the body of the coffee machine, before or when the coffee machine is started, the user rotates the opening and closing member to the open position, the discharge channel is opened, and the coffee beans in the storage cavity can fall into the grinder through the discharge channel, and the grinder grinds the coffee beans into coffee powder. After the coffee machine makes coffee, the user rotates the opening and closing member to the closed position. Since the opening and closing member has an interference fit with the discharge channel, the discharge channel is completely closed by the closing member, and outdoor air cannot enter the storage cavity through the discharge channel, so that the storage cavity can be kept airtight and the storage time of the coffee beans in the storage cavity can be extended. At the same time, when the opening and closing member is rotated to the closed position and the hopper is removed from the body of the coffee machine, the coffee beans in the storage cavity will not spill.

Detailed implementation manners

[0044] This embodiment provides a coffee machine, which includes a hopper 100 and a machine body. The hopper 100 and the machine body are detachably connected. The machine body includes a grinder, and the grinder is communicated with the hopper 100. The hopper 100 is used for storing coffee beans to be ground and can convey the coffee beans into the grinder. The grinder is used for grinding the coffee beans conveyed by the hopper 100 into coffee powder.

[0045] As Figures 1 to 3 shown, Figures 1 to 3 shows the structure of a hopper 100 in this embodiment. The hopper 100 includes a storage bin 1, an opening and closing member 2 and a lever 4.

[0046] The storage bin 1 is provided with a storage cavity 11 and a discharge channel 12. The storage cavity 11 is a cavity for storing coffee beans. The discharge channel 12 extends downward from the storage cavity 11. The discharge channel 12 can be a straight pipe, and the discharge channel 12 can extend vertically downward from the bottom of the storage cavity 11. The discharge channel 12 is communicated with the storage cavity 11. The end of the discharge channel 12 facing away from the storage cavity 11 is used for connecting to the grinder of the coffee machine. The coffee beans in the storage cavity 11 can be conveyed into the grinder through the discharge channel 12.

[0047] The opening and closing member 2 is disposed in the discharge passage 12 and is used to open and close the discharge passage 12. The opening and closing member 2 is rotatably connected to the inner side wall of the discharge passage 12. In this embodiment, the opening and closing member 2 is configured in a flat plate shape, and the shape of the plate surface of the opening and closing member 2 is the same as the cross-sectional shape of the discharge passage 12. The plate surface of the opening and closing member 2 is configured to be slightly larger than the cross-section of the discharge passage 12. The opening and closing member 2 is configured to be able to rotate about a rotation axis, which is parallel to the plate surface of the opening and closing member 2 and perpendicular to the extending direction of the discharge passage 12. As Figure 2 , 3 shown, the opening and closing member 2 can rotate to the open position where the discharge passage 12 is opened and can also rotate to the closed position where the discharge passage 12 is closed, and the opening and closing member 2 can reciprocally rotate between the open position and the closed position.

[0048] In this embodiment, as Figure 2 shown, when the opening and closing member 2 rotates to a position where the plate surface of the closing member is not perpendicular to the extending direction of the discharge passage 12 and the gap between the opening and closing member 2 and the discharge passage 12 can pass coffee beans, the opening and closing member 2 is in the open position. At this time, the coffee beans in the storage cavity 11 can enter the discharge passage 12 through the gap between the opening and closing member 2 and the discharge passage 12 and fall into the grinder under the guidance of the discharge passage 12. The preferred open position of the opening and closing member 2 is a position where the plate surface of the opening and closing member 2 is parallel to the extending direction of the discharge passage 12. At this time, the width of the gap between the opening and closing member 2 and the discharge passage 12 reaches the maximum, and the coffee beans can pass through the gap smoothly and quickly.

[0049] As Figure 3 shown, when the opening and closing member 2 rotates to a position where the plate surface of the closing member is perpendicular to the extending direction of the discharge passage 12, the opening and closing member 2 is in the closed position. Since the plate surface of the opening and closing member 2 is slightly larger than the cross-section of the discharge passage 12, there is an interference fit between the opening and closing member 2 and the discharge passage 12, so that there is no gap between the opening and closing member 2 and the discharge passage 12, and the opening and closing member 2 completely closes the discharge passage 12. The coffee beans in the storage cavity 11 cannot fall into the discharge passage 12, and the air outside the storage cavity 11 cannot enter the storage cavity 11 through the discharge passage 12.

[0050] In this way, after the hopper 100 is installed on the body of the coffee machine, before or when the coffee machine is started, the user rotates the opening and closing member 2 to the open position, the discharge passage 12 is opened, and the coffee beans in the storage cavity 11 can fall into the grinder through the discharge passage 12, and the grinder grinds the coffee beans into coffee powder. After the coffee machine makes coffee, the user rotates the opening and closing member 2 to the closed position, and the discharge passage 12 is completely closed by the closing member. The outdoor air cannot enter the storage cavity 11 through the discharge passage 12, so that the storage cavity 11 can be kept airtight, and the storage time of the coffee beans in the storage cavity 11 can be extended. At the same time, when the opening and closing member 2 rotates to the closed position, when the hopper 100 is removed from the body of the coffee machine, the coffee beans in the storage cavity 11 will not spill.

[0051] In addition, when the discharge passage 12 has coffee beans, during the process of rotating the opening and closing member 2 from the open position to the closed position, the starting member flips to push aside the coffee beans, thereby preventing the coffee beans from jamming the starting member and causing the starting member to fail to close the discharge passage 12.

[0052] In a schematic embodiment, as Figure 6 shown, two shaft holes 121 are provided on the wall surface of the discharge passage 12, and the two shaft holes 121 are respectively provided on the opposite side walls of the discharge passage 12. The two shaft holes 121 are coaxially arranged. The axial directions of the two shaft holes 121 are perpendicular to the extending direction of the discharge passage 12.

[0053] The storage bin 100 further includes a rotating shaft 3. The rotating shaft 3 is configured as a straight bar. The extending direction of the rotating shaft 3 is parallel to the plate surface of the opening and closing member 2. The rotating shaft 3 is connected to the opening and closing member 2. A connecting portion 23 is provided on one plate surface of the opening and closing member 2. The connecting portion 23 may be a protrusion protruding from the plate surface. The connecting portion 23 may be provided in the middle region of the plate surface. As Figure 7 shown, a through hole 231 is provided on the connecting portion 23. The through hole 231 is parallel to the plate surface of the opening and closing member 2, and the rotating shaft 3 passes through the through hole 231. The opposite ends of the rotating shaft 3 are respectively inserted into the two shaft holes 121 of the discharge pipe. A clearance fit is provided between the rotating shaft 3 and the shaft hole 121, and the rotating shaft 3 can rotate relative to the shaft hole 121.

[0054] The opening and closing member 2 is rotatably connected to the storage bin 1 through the rotating shaft 3. The opening and closing member 2 can only rotate around the rotating shaft 3, and the central axis of the rotating shaft 3 is the rotating shaft 3 of the opening and closing member 2.

[0055] In a schematic embodiment, when the opening and closing member 2 is in the closed position, the plate surface of the opening and closing member 2 is perpendicular to the extending direction of the discharge passage 12. One plate surface of the opening and closing member 2 faces the storage cavity 11, and the other plate surface of the opening and closing member 2 faces away from the storage cavity 11. The connecting portion 23 is connected to the plate surface of the opening and closing member 2 facing away from the storage cavity 11, and the rotating shaft 3 is located on the side of the opening and closing member 2 facing away from the storage cavity 11.

[0056] When the rotating shaft 3 is located on the side of the opening and closing member 2 facing away from the storage cavity 11, the shaft holes 121 on the wall surface of the discharge passage 12 are also located on the side of the opening and closing member 2 facing away from the storage cavity 11, so that the shaft holes 121 cannot communicate with the storage cavity 11, further enhancing the sealing performance of the storage cavity 11.

[0057] In a schematic embodiment, the storage bin 1 further includes a blocking portion 13. The blocking portion 13 is disposed on the inner sidewall of the storage cavity 11 near the discharge channel 12. The blocking portion 13 extends radially inward from the inner sidewall of the storage cavity 11. The blocking portion 13 is located above the discharge channel 12. The inlet of the discharge channel 12 facing the storage cavity 11 is spaced apart from the blocking portion 13, and the blocking portion 13 can block a part of the area of the inlet. The blocking portion 13 may block half of the area of the inlet.

[0058] The surface of the blocking portion 13 facing the discharge channel 12 is formed into a guiding concave surface 131. The guiding concave surface 131 is a smooth curved surface and smoothly transitions with the inner side surface of the discharge channel 12. When the opening and closing member 2 reciprocally rotates between the open position and the closed position, the arc surface formed by the movement locus of the edge of the opening and closing member 2 on the side close to the blocking portion 13 coincides with the guiding concave surface 131 of the blocking portion 13. When the opening and closing member 2 reciprocally rotates between the open position and the closed position, the edge of the opening and closing member 2 on the side close to the blocking portion 13 can slide along the guiding concave surface 131 of the blocking portion 13.

[0059] As Figure 2 , 4 shown, when the opening and closing member 2 is in the open position, due to the blocking of the blocking portion 13, there is no accumulation of coffee beans below the side of the opening and closing member 2 close to the blocking portion 13. When it is necessary to close the discharge channel 12, the opening and closing member 2 is rotated from the open position to the closed position. The side of the opening and closing member 2 close to the blocking portion 13 rotates downward. Since the space below this side of the opening and closing member 2 is empty, the coffee beans will not obstruct the movement of this side. At the same time, the side of the opening and closing member 2 facing away from the blocking portion 13 rotates upward. The upper part of this side of the opening and closing member 2 is open, and this side of the opening and closing member can push the coffee beans obstructing its movement in the discharge channel 12 back into the storage cavity 11, so that the opening and closing member 2 can rotate smoothly, and the coffee beans in the discharge channel 12 will not jam the opening and closing member 2.

[0060] As Figure 3 , 5 shown, when the opening and closing member 2 is in the closed position, since a part of the coffee beans in the discharge channel 12 have been pushed back into the storage cavity 11 during the process of closing the opening and closing member 2 before, the discharge channel 12 below the opening and closing member 2 is relatively empty at this time. When it is necessary to open the discharge channel 12, the opening and closing member 2 is rotated from the closed position to the open position. Since the discharge channel 12 below the opening and closing member 2 is relatively empty and the upper part of the opening and closing member 2 is an open space, there is sufficient space to make way for the coffee beans, the opening and closing member 2 can rotate smoothly, and the coffee beans will not jam the opening and closing member 2.

[0061] Through the cooperation between the guiding concave surface 131 of the blocking part 13 and the opening and closing member 2, a part of the open space can be separated, so that the discharge channel 12 below the opening and closing member 2 can never be filled with coffee beans, and the coffee beans in the discharge channel 12 cannot jam the opening and closing member 2, ensuring the smoothness and slipperiness of the entire movement process of the opening and closing member 2, and avoiding the situation that the opening and closing member 2 cannot rotate due to a large amount of coffee beans below the opening and closing member 2 and the occurrence of bean jamming between the opening and closing member 2 and the inner wall of the storage bin 1. At the same time, during the process of the opening and closing member 2 closing the discharge channel 12, some of the remaining coffee beans in the discharge channel 12 are re-dialed into the storage bin 1, which can store the unused coffee beans in the storage bin 1 to the greatest extent. The storage time of the coffee beans is extended through the sealed storage bin 1, and the quality of the coffee beans is maintained unchanged for a long time.

[0062] In a schematic embodiment, the cross-section of the discharge channel 12 is circular, and the discharge channel 12 is a circular channel. The opening and closing member 2 is configured in a circular plate shape. The guiding concave surface 131 of the blocking part 13 is a spherical surface.

[0063] The cross-sectional shape of the discharge channel 12 is adapted to the shape of the opening and closing member 2, and the shape of the opening and closing member 2 is adapted to the shape of the guiding concave surface 131 of the blocking part 13. At the same time, the shapes of the discharge channel 12, the opening and closing member 2, and the blocking part 13 with such shapes are smooth, and it is less likely to occur the situation of bean jamming.

[0064] In a schematic embodiment, the bin 100 further includes a dial rod 4. The dial rod 4 is configured as a rod-shaped structure, which can be a bent rod-shaped structure. One end of the dial rod 4 is connected to the opening and closing member 2. When the opening and closing member 2 is in the closed position, the dial rod 4 can be connected to the plate surface of the opening and closing member 2 facing the storage cavity 11. The dial rod 4 and the opening and closing member 2 can be an integrally formed structure. The end of the dial rod 4 facing away from the opening and closing member 2 extends into the storage cavity 11. The dial rod 4 can extend to the end of the storage cavity 11 facing away from the discharge channel 12.

[0065] The user can operate the dial rod 4 to drive the opening and closing member 2 to rotate, which is labor-saving and convenient.

[0066] In a schematic embodiment, the dial rod 4 is arranged such that when the starting member rotates to the closed position, one side of the dial rod 4 abuts against the side of the blocking part 13 facing away from the discharge channel 12. The dial rod 4 is further arranged such that when the starting member rotates to the open position, the other side of the dial rod 4 abuts against the inner side wall of the discharge channel 12, and this inner side wall is arranged opposite to the blocking part 13.

[0067] In this way, when the lever 4 swings towards the side close to the blocking portion 13, it can drive the opening and closing member 2 to rotate from the open position to the closed position. When the opening and closing member 2 rotates to the closed position, the lever 4 abuts against the side of the blocking portion 13 facing away from the discharge channel 12. The blocking portion 13 limits the lever 4 so that the lever 4 cannot continue to rotate, and the opening and closing member 2 can accurately stop at the closed position. When the lever 4 swings towards the side away from the blocking portion 13, it can drive the opening and closing member 2 to rotate from the closed position to the open position. When the opening and closing member 2 rotates to the open position, the lever 4 abuts against the inner side wall of the discharge channel 12. The inner side wall of the discharge channel 12 limits the lever 4 so that the lever 4 cannot continue to rotate, and the opening and closing member 2 can accurately stop at the open position.

[0068] In a schematic embodiment, as Figure 7 , 8 shown, the lever 4 includes a first straight rod 41 and a second straight rod 42. Both the first straight rod 41 and the second straight rod 42 are configured as straight strips. One end of the first straight rod 41 is connected to the opening and closing member 2 and is perpendicular to the opening and closing member 2. The connection point of the first straight rod 41 on the opening and closing member 2 can be located on the side of the rotating shaft 3 facing away from the blocking portion 13, and it is more labor-saving when the first straight rod 41 drives the opening and closing member 2 to rotate. One end of the second straight rod 42 is connected to the end of the first straight rod 41 facing away from the opening and closing member 2. The second straight rod 42 is perpendicular to the first straight rod 41, and the second straight rod 42 is also perpendicular to the rotating shaft 3. The second straight rod 42 extends from the first straight rod 41 towards the direction close to the blocking portion 13. The distance between the side of the second straight rod 42 close to the opening and closing member 2 and the opening and closing member 2 can be equal to the distance between the opening and closing member 2 and the side of the blocking portion 13 facing away from the discharge channel 12 when the opening and closing member 2 is in the closed position. The distance between the side of the second straight rod 42 facing away from the opening and closing member 2 and the opening and closing member 2 can be equal to the distance between the side of the discharge channel 12 facing away from the blocking portion 13 and the opening and closing member 2 at the open position.

[0069] When the opening and closing member 2 rotates to the closed position, the second straight rod 42 is located on the side of the blocking portion 13 facing away from the discharge channel 12, and the side surface of the second straight rod 42 abuts against the side of the blocking portion 13 facing away from the discharge channel 12. When the opening and closing member 2 rotates to the open position, a part of the second straight rod 42 is located inside the discharge channel 12, and the other side surface of the second straight rod 42 abuts against the inner side wall of the discharge channel 12 opposite to the blocking portion 13.

[0070] The first straight rod 41 and the second straight rod 42 are arranged perpendicular to each other, which can form a clearance space between the second straight rod 42 and the opening and closing member 2. When the lever 4 rotates towards the direction close to the blocking portion 13, it gives way to the blocking portion 13, so that the lever 4 will not interfere with the blocking portion 13 before rotating in place. At the same time, the first straight rod 41 and the second straight rod 42 form a bend, which gives way to the inner side wall of the discharge channel 12 when the lever 4 rotates towards the direction away from the blocking portion 13, so that the lever 4 will not interfere with the inner side wall of the discharge channel 12 before rotating in place.

[0071] In a schematic embodiment, the lever 4 further includes a third straight rod 43 and a fourth straight rod 44. The third straight rod 43 is perpendicular to the second straight rod 42. One end of the third straight rod 43 is connected to the end of the second straight rod 42 facing away from the first straight rod 41. The other end of the third straight rod 43 extends in a direction away from the opening and closing member 2. The third straight rod 43 is parallel to the first straight rod 41. One end of the fourth straight rod 44 is connected to the end of the third straight rod 43 facing away from the second straight rod 42. The other end of the fourth straight rod 44 extends in a direction away from the second straight rod 42.

[0072] When the opening and closing member 2 rotates to the open position, the connection part of the third straight rod 43 and the fourth straight rod 44 abuts against the inner wall of the storage cavity 11 on the side away from the blocking part 13, and the inner wall of the storage cavity 11 limits the lever 4.

[0073] In a schematic embodiment, as Figure 1 、 3 shown, the opening and closing member 2 includes a main body 21 and a first sealing ring 22. The main body 21 is configured as a plate-like structure, such as a circular plate-like structure. The main body 21 has rigidity. The main body 21 can be made of a metal material or a hard plastic. The connecting part 23 is arranged on one plate surface of the main body 21.

[0074] The first sealing ring 22 is annular. The first sealing ring 22 surrounds the main body 21 and is clamped on the side surface of the main body 21. The first sealing member has elasticity. The first sealing member can be a rubber member.

[0075] When the opening and closing member 2 rotates to the closed position, the first sealing ring 22 is clamped between the main body 21 and the inner wall of the discharge channel 12 and undergoes elastic deformation under the extrusion of the main body 21 and the inner wall of the discharge channel 12. The first sealing ring 22 can completely seal the annular gap between the main body 21 and the discharge channel 12. The opening and closing member 2 with this structure has better sealing performance.

[0076] In a schematic embodiment, an annular groove 211 is provided on the side surface of the main body 21. The annular groove 211 surrounds the main body 21. The depth of the annular groove 211 is less than the diameter of the first sealing ring 22. The first sealing ring 22 is clamped on the annular groove 211. The inner edge of the first sealing ring 22 is embedded in the annular groove 211, and the outer edge of the first sealing ring 22 extends out of the annular groove 211.

[0077] The first sealing ring 22 is installed in the annular groove 211, and the installation is stable and it is not easy to fall off from the main body 21.

[0078] In a schematic embodiment, a feed port 111 is further provided at the top of the storage cavity 11. The feed port 111 can be set as a circular opening. Coffee beans can be fed into the storage cavity 11 through the feed port 111.

[0079] The silo 100 further includes a silo cover 5 and a second sealing ring 6. The silo cover 5 can be closed on the feed inlet 111 to close the feed inlet 111. The silo cover 5 includes a cover plate 51 and a sealing ring 52. The cover plate 51 can be set as a circular flat plate. The plate surface of the cover plate 51 is larger than the cross-section of the feed inlet 111. The sealing ring 52 is arranged on one plate surface of the cover plate 51. The sealing ring 52 can be arranged at the edge of the plate surface of the cover plate 51. The sealing ring 52 can be constructed as a cylindrical shape. The second sealing ring 6 is hoop-shaped on the sealing ring 52. The second sealing ring 6 can be a rubber part.

[0080] When the silo cover 5 is closed on the feed inlet 111, the cover plate 51 covers the feed inlet 111, the sealing ring 52 extends into the feed inlet 111, an annular gap is formed between the outer peripheral surface of the sealing ring 52 and the inner peripheral surface of the feed inlet 111, and the second sealing ring 6 can block the annular gap, so that the feed inlet 111 can be tightly sealed.

[0081] In a schematic embodiment, the silo 100 further includes a base body 7. The base body 7 is arranged below the storage bin 1. The top of the base body 7 is connected to the bottom of the storage bin 1. The base body 7 can be connected to the end of the discharge channel 12 facing away from the storage cavity 11. The bottom surface of the base body 7 can be a horizontal plane. A guiding channel 71 is arranged on the base body 7. The guiding channel 71 can be set as a vertical channel. The top end of the guiding channel 71 is connected to the end of the discharge channel 12 facing away from the storage cavity 11. The bottom end of the guiding channel 71 can be used to be connected to the inlet of the grinder. The base body 7 is set to be detachably connected to the body of the coffee machine.

[0082] In another schematic embodiment, the lever 4 is arranged outside the storage bin 1. One end of the rotating shaft 3 extends outside the storage bin 1 and is connected to one end of the lever 4. The extending direction of the lever 4 is perpendicular to the extending direction of the rotating shaft 3.

[0083] The lever 4 can drive the opening and closing member 2 to rotate by driving the rotating shaft 3 to rotate. By arranging the lever 4 outside the storage bin 1, the user does not need to open the silo cover 5 when operating the lever 4, which is more convenient.

[0084] In another schematic embodiment, as Figure 9 shown, the inner peripheral surface of the discharge channel 12 includes a spherical surface 12a. The opening and closing member 2a is constructed as a spherical shape. The opening and closing member 2a is arranged in the discharge channel 12, the spherical surface 12a of the discharge channel 12 surrounds the opening and closing member 2a, and the opening and closing member 2a is restricted by the spherical surface 12a of the discharge channel 12 and can only rotate. A communication channel 21a is arranged on the opening and closing member 2a, and the communication channel 21a penetrates through the opening and closing member 2a. The communication channel 21a can pass through the center of the sphere of the opening and closing member 2a.

[0085] When the opening and closing member 2a is in the open position, the extending direction of the communication channel 21a of the opening and closing member 2a is parallel to the extending direction of the discharge channel 12. At this time, the discharge channel 12 is opened, and the coffee beans in the storage chamber 11 can pass through the communication channel 21a. When the opening and closing member 2a is in the closed position, the extending direction of the communication channel 21a is perpendicular to the extending direction of the discharge channel 12. At this time, the discharge channel 12 is closed, and the coffee beans in the storage chamber 11 cannot pass through the communication channel 21a.
