Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a movable bean box structure that enables sealing and vacuuming. Background Technology

[0002] In the food processing and beverage production field, bean grinders are the core equipment for achieving refined processing of bean materials. Their bean hoppers, serving as storage and pre-supply components, directly affect the storage quality of the bean materials and the flavor and taste of the final beverage. Existing bean hoppers mostly employ simple flip-top or snap-on lid designs, achieving a "semi-seal" connection between the lid and the hopper opening only through rigid contact or simple rubber gaskets, failing to create a completely sealed space isolated from the external environment. This structural defect makes the interior of the bean hopper highly susceptible to exchange with external air and moisture: on the one hand, oxygen in the air reacts with the bean materials in an oxidation reaction, destroying flavor compounds and causing flavor aging, which in turn causes the beverage made from the ground material to lose its original aroma and even develop off-flavors such as sourness, astringency, or rancidity; on the other hand, moisture from the external environment can penetrate into the bean hopper, causing the bean materials to become damp. This not only alters the physical properties of the materials and affects the uniformity of the grinding process but may also provide conditions for microbial growth, posing a food safety hazard. To solve these problems, a mobile bean hopper structure that can achieve sealing and vacuuming is proposed. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the bean hoppers of existing bean grinding products cannot achieve a true sealing effect, and beans are prone to moisture and oxidation if left for a long time, resulting in a change in the flavor of the beverage.

[0004] The present invention adopts the following technical solution: A movable bean container structure capable of being sealed and vacuumed includes a bean hopper, a bean hopper cover with a vacuum suction port, a vacuum capsule at the vacuum suction port to ensure the airtightness of the bean hopper, a bean hopper support below the bean hopper, a hopper door and a hopper door bracket between the hopper support and the bean hopper, a sliding groove for rotating the hopper door inside the hopper support, a sliding claw on the outside of the hopper door located on the sliding groove, a positioning groove on the hopper door bracket that mates with the sliding claw, and a swing rod with a hopper door gear on the hopper support. The hopper door gear mates with the hopper door bracket, and the swing rod drives the hopper door bracket to rotate, releasing the beans from the bean hopper. Furthermore, the bean hopper cover is positioned above the bean hopper, and a sealing ring is used to seal the two. The vacuum adsorption port is located on the upper surface of the bean hopper cover, and a through exhaust valve is provided inside the vacuum adsorption port. A rubber vacuum capsule is installed inside the exhaust valve, and there are several exhaust channels for air to pass through between the vacuum capsule and the exhaust valve. Furthermore, the bottom of the bean hopper has a bean inlet, and the middle of the hopper door has a conical protrusion for engaging with the bean inlet to close the bean hopper. The hopper door support is annular, with downwardly extending limiting blocks on the inner wall. The limiting blocks form positioning grooves for the sliding claws of the hopper door to move up and down. The top of the hopper door support has several sets of openings to allow the sliding claws of the hopper door to retain an upward channel. Furthermore, the inner wall of the bean hopper support has several sets of inclined sliding grooves, and the upper and lower ends of the sliding grooves have placement platforms for the sliding claws to rest on. There is an inclined guide rail between the two placement platforms for relative sliding with the sliding claws. Furthermore, the silo door bracket is mounted on the bean silo bracket, the lower surface of the silo door bracket has annular protrusions, there is an annular channel between the silo door bracket and the bean silo bracket, the swing rod and the silo door gear are located in the annular channel, the silo door gear meshes with the protrusions of the silo door bracket, the swing rod passes through the bean silo bracket, and the end of the swing rod is provided with the silo door gear, the swing rod is used to drive the silo door bracket to rotate along the bean silo bracket; Furthermore, the sliding claw of the compartment door is L-shaped, and the crossbar of the sliding claw extends into the positioning groove formed by the limiting block of the compartment door bracket. The compartment door rotates with the rotation of the compartment door bracket and moves up and down along the sliding groove. Furthermore, a decorative ring is provided between the bean hopper and the bean hopper support to cover the exposed internal parts; Furthermore, the swing arm is L-shaped, with the horizontal part extending into the bean hopper support and the vertical part pointing straight upwards, facilitating operation.

[0005] The beneficial effects of this utility model are: The bean hopper lid's sealing ring, vacuum capsule, and conical protrusion on the hopper door achieve a double seal from top to bottom. Combined with the vacuum structure, it can actively expel air from the hopper, effectively isolating oxygen and moisture, significantly delaying the oxidation and moisture absorption of bean materials, extending the shelf life, and ensuring the stability of beverage flavor. The L-shaped rocker arm and gear transmission structure allows the door to be opened and closed simply by rotating the rocker arm, making operation effortless. The cooperation between the sliding pawl and the inclined slide groove ensures a stable door movement trajectory and prevents loosening when sealed, thus improving reliability.

[0010] Example 1 This utility model provides a mobile bean container structure that can achieve a sealable vacuum, including a bean container 1, a bean container cover 2 on top of the bean container 1, and a sealing ring 3 to achieve a preliminary seal between the two to ensure no gaps at the interface. A vacuum adsorption port 16 is provided in the middle of the upper surface of the bean container cover 2, and an exhaust valve 4 is installed through the vacuum adsorption port 16. A rubber vacuum capsule 5 is installed inside the exhaust valve 4. Multiple exhaust channels are provided between the vacuum capsule 5 and the exhaust valve 4 for air circulation. When an external vacuuming device is connected to the vacuum adsorption port 16, air is drawn out through the exhaust channels between the exhaust valve 4 and the vacuum capsule 5. The vacuum capsule 5 expands under negative pressure, tightly blocking the exhaust channels and forming a seal. The external vacuuming device is always connected to the vacuum adsorption port 16, thereby establishing a vacuum environment inside the bean container 1. A bean hopper support 11 is provided below the bean hopper 1, and a hopper door 7 and a hopper door bracket 9 for installing the hopper door 7 are provided between the bean hopper support 11 and the bean hopper 1. The bottom of the bean hopper 1 is provided with a bean outlet 15 for discharging bean materials. The middle of the hopper door 7 is designed with a conical protrusion that cooperates with the bean outlet 15. The conical surface contact achieves a tight seal to prevent leakage. Multiple L-shaped sliding claws 8 are fixed on the outside of the hopper door 7. The inside of the bean hopper support 11 is provided with an inclined slide groove 12. The sliding claws 8 rest on the slide groove 12. The upper and lower ends of the slide groove 12 are provided with placement platforms for the hopper door support 9 to stop and position. There is an inclined guide rail between the two placement platforms. When the hopper door support 9 rotates, it drives the hopper door 7 to rotate. At the same time, the inclined guide rail drives the hopper door 7 to move up and down. The door support 9 is ring-shaped and installed on the bean hopper support 11. Its inner wall is provided with downwardly extending limiting blocks, and positioning grooves 10 are formed between the limiting blocks. These grooves cooperate with the horizontal bar of the sliding claw 8 to drive the sliding claw 8 to move up and down. The top of the door support 9 has several sets of openings to provide an upward channel for the vertical bar of the sliding claw 8. An L-shaped swing arm 14 is installed on the bean hopper support 11. The horizontal part of the swing arm 14 extends into the bean hopper support 11, and the end is equipped with a hopper door gear 13; the vertical part faces vertically upward, which is convenient for manual operation. The lower surface of the silo door bracket 9 is provided with annular protrusions that mesh with the silo door gear 13, and an annular channel is formed between the two for the movement of the swing rod 14 and the silo door gear 13. When the user rotates the vertical part of the swing rod 14, the silo door gear 13 drives the silo door bracket 9 to rotate. The silo door bracket 9 drives the silo door 7 with sliding claw 8 to rotate through the positioning groove 10 formed by the internal limiting block. At the same time, it moves up and down along the inclined sliding groove 12 of the bean silo bracket 11. The vertical part of the L-shaped sliding claw 8 passes through the opening at the upper end of the silo door bracket 9, providing an upward channel for the sliding claw 8. When the sliding claw 8 slides from the upper placement platform to the lower placement platform along the guide rail, the silo door 7 descends and rotates, and the conical protrusion disengages from the lower bean opening 15, and the beans are discharged from the lower bean opening 15. When the swing rod 14 is rotated in the opposite direction, the sliding claw 8 returns to the upper placement platform, the silo door 7 rises and rotates, and the conical protrusion closes the lower bean opening 15, completing the seal. A decorative ring 6 is provided between the bean hopper 1 and the bean hopper support 11 to cover exposed parts such as the internal sliding claw 8 and gears, thereby improving the aesthetics and safety of the structure.
