[0002] In the coffee roasting process, the rationality of the bean feeding structure directly affects the roasting efficiency, safety, and equipment cleanliness.

[0003] Existing coffee roasters typically use a simple flip-top design for the bean inlet, which has the following drawbacks: During roasting, coffee beans shed silver husks (the outer layer of the coffee bean that detaches), and a small amount of waste gas is generated, which needs to be exhausted through a ventilation path. In the existing structure, the connection between the bean inlet and the ventilation system is not smooth, which can easily lead to the accumulation of silver husks in the flip-top bean inlet cavity, increasing the difficulty of cleaning, and may even affect the ventilation efficiency due to silver husk blockage, thereby causing abnormal temperature in the roasting cavity. Utility Model Content

The inlet of the shavings collection module is connected to the first vent of the bean feeding flip-top mechanism, and is used to collect coffee shavings discharged from the roasting module via the preset airflow path. The air filtration module is located behind the shavings collection module.

[0015] Compared with the prior art, the technical solution provided in this application has the following advantages: This application, through the precise alignment of the flap groove with the bean inlet chamber, effectively prevents the overflow of hot air and smoke, and the entry of external dust, thus ensuring roasting efficiency while improving coffee bean quality and the cleanliness of the operating environment.

Therefore, they should not be construed as limiting the present invention.

[0022] like Figure 1 - Figure 7 As shown, this application provides a bean inlet flip-top mechanism 1 for a coffee roaster 100. The coffee roaster 100 includes a body 1001, a roasting module, and a shavings collection and exhaust module. The bean inlet flip-top mechanism 1 includes: The chassis 10 is connected to the machine body 1001. The chassis 10 has a bean inlet chamber 11. The bottom of the bean inlet chamber 11 has a bean inlet 12. The side wall of the bean inlet chamber 11 has a first ventilation opening 13. The bean inlet 12 is connected to the bean drying module. The first ventilation opening 13 is connected to the silver skin collection and exhaust module. A flip cover 20, one end of which is rotatably connected to the chassis 10, to switch between a closed position covering the bean inlet cavity 11 and an open position opening the bean inlet cavity 11. A groove 21 is provided on the bottom surface of the flip cover 20, and a second ventilation opening 22 is provided on the side wall of the groove 21. When the flip cover 20 is in the closed position, the opening edge of the groove 21 is connected to the opening periphery of the bean inlet 12 and forms a communication, and the second vent 22 is connected to the first vent 13 and forms a communication.

[0023] The chassis 10 is fixedly connected to the body 1001 of the coffee roaster 100, serving as the basic supporting component of the bean feeding mechanism. A bean feeding chamber 11 is provided on the chassis 10; this chamber is an open space at the top for temporarily storing coffee beans to be roasted. A bean inlet 12 is located at the bottom of the bean feeding chamber 11, communicating with the roasting module, allowing the coffee beans in the chamber to fall into the roasting module for roasting under gravity. A first ventilation opening 13 is provided on the side wall of the bean feeding chamber 11, communicating with the shavings collection and exhaust module of the coffee roaster 100, serving as a channel for the discharge of shavings and exhaust gases during the roasting process.

[0024] One end of the flip cover 20 is rotatably connected to the base 10 and can rotate around a hinge axis, thereby switching between two positions: a closed position covering the bean inlet 11 (for sealing during roasting) and an open position opening the bean inlet 11 (for adding coffee beans). The bottom surface of the flip cover 20 (the side facing the base 10) has a groove 21, the shape of which is adapted to the upper opening of the bean inlet 11; the side wall of the groove 21 has a second vent 22, the position of which corresponds to the first vent 13 on the base 10.

[0025] When the flip cover 20 is in the closed position, the periphery of the opening of the groove 21 precisely aligns with the periphery of the opening of the bean inlet chamber 11, forming a sealed connection. This ensures that the coffee beans in the bean inlet chamber 11 can only enter the roasting module through the bean inlet 12, and external impurities cannot enter. The second vent 22 is fully aligned with and connected to the first vent 13, forming a complete ventilation path. This allows the silver skin and exhaust gas generated by the roasting module to sequentially pass through the bean inlet 12, the bean inlet chamber 11, the first vent 13, and the second vent 22 into the silver skin collection and exhaust module.

[0026] Furthermore, the bean inlet flip-top mechanism 1 also includes a sealing ring 40, which is disposed between the flip-top 20 and the base 10 and along the opening edge of the bean inlet 12.

[0027] To enhance the sealing between the flip cover 20 and the base 10, the bean-feeding flip cover mechanism 1 also includes a sealing ring 40, which is disposed between the flip cover 20 and the base 10 and along the opening edge of the bean-feeding inlet 12. When the flip cover 20 is closed, the sealing ring 40 is pressed between the periphery of the groove 21 of the flip cover 20 and the periphery of the opening of the bean-feeding cavity 11, further preventing hot air, smoke, and external dust from escaping and entering.

[0028] During roasting, the temperature of the roasting module is usually high. If there are gaps in the bean inlet 12, heat will continuously escape, leading to increased energy consumption and decreased efficiency. Simultaneously, fine dust generated during roasting may diffuse into the operating environment through these gaps, affecting the user experience. The sealing ring 40 is positioned along the edge of the bean inlet 12. When the flip cover 20 is closed, the sealing ring 40 is pressed tightly against the base 10 by the flip cover 20, forming a flexible sealing barrier. This effectively prevents heat and dust from escaping, reducing heat loss and energy consumption while maintaining a clean operating environment. Furthermore, coffee beans must be clean before roasting. If the bean inlet 12 is not sealed tightly, dust, hair, and other impurities in the air may enter the bean feeding chamber 11 or the roasting module through gaps, contaminating the coffee beans and affecting roasting quality. The sealing ring 40 fills the gap between the flip cover 20 and the base 10, forming a physical barrier to ensure that the coffee beans are not contaminated by external impurities during feeding and roasting, guaranteeing the final taste and hygiene safety of the coffee. Furthermore, in actual production, there may be slight deviations in the machining accuracy of the chassis 10 and the flip cover 20, leading to unstable sealing performance during rigid connection. The sealing ring 40 has a certain degree of elasticity and can adapt to the machining errors of different parts through its own deformation, ensuring reliable sealing even with slight dimensional deviations, thus improving the production compatibility and operational stability of the mechanism.

[0029] Furthermore, the bean-feeding flip-top mechanism 1 also includes a locking assembly 60, which includes a locking buckle 61 located at the front end of the flip-top 20 and a latching position 15 located at the front end of the chassis 10. When the flip-top 20 is in the closed position, the locking buckle 61 and the latching position 15 are detachably engaged.

[0030] To ensure the stability of the flip-top 20 after it is closed, the bean feeding flip-top mechanism 1 also includes a locking assembly 60, specifically a locking latch 61 located at the front end of the flip-top 20 and a latch 15 located at the front end of the chassis 10. The engagement structure of the locking latch 61 and the latch 15 is simple. The user only needs to lightly press the front end when closing the flip-top 20 to lock it; when opening, simply move the locking latch 61 to disengage from the latch 15. No complicated operation is required. While ensuring stability, the convenience of bean feeding operation is maintained, balancing functionality and user experience. During the roasting process, the roasting module is at a high temperature. If the flip-top 20 is accidentally opened due to vibration or accidental contact, the hot air may directly contact the user, posing a risk of burns. At the same time, a large influx of cold air from outside will cause a sudden drop in the temperature of the roasting chamber, disrupting the roasting curve and affecting the quality of the coffee beans. The detachable snap-fit ​​of the locking latch 61 and the latch 15 can firmly lock the flip-top 20 in the closed position. Even if the equipment vibrates during operation or is subjected to slight external force, it will not be easily opened, structurally eliminating safety hazards and the risk of roasting interruption. On the other hand, the sealing performance of the flip cover 20 depends on its tight fit with the chassis 10. If the flip cover 20 is loose after being closed, gaps will appear at the joint between the sealing ring 40 and the vent, weakening the sealing and ventilation effects. The locking assembly 60 presses the flip cover 20 tightly onto the chassis 10 through the snapping force, ensuring a tight fit between the periphery of the groove 21 and the periphery of the bean inlet cavity 11 and the vent, indirectly enhancing the sealing reliability of the sealing ring 40 and the ventilation path, and preventing heat leakage or silver coating blockage caused by loosening.

[0031] Furthermore, the latch assembly 60 also includes a pivot 63 and a spring 64. The latch 61 is rotatably mounted on the flip cover 20 via the pivot 63. One end of the spring 64 abuts against the flip cover 20, and the other end abuts against the latch 61.

[0032] Specifically, one end of the spring 64 abuts against the flip cover 20, and the other end abuts against the latch 61. When the flip cover 20 is closed, the latch 61 automatically rotates towards the latch position 15 under the elastic force of the spring 64, completing the latch engagement without the user applying additional force. This design simplifies the operation process, allowing even novice users to easily close the flip cover 20, avoiding sealing failure due to forgetting to lock it, and improving the ease of use of the device. On the other hand, the elastic force of the spring 64 has a certain buffering capacity, which can accommodate minor assembly errors between the latch 61 and the latch position 15. When there is a slight deviation in their positions, the spring 64 will compensate through deformation to ensure that the latch 61 is always tightly fitted with the latch position 15, avoiding a loose lock. At the same time, the stable elastic force ensures that the locking force is moderate, neither too loose to cause accidental opening nor too tight to cause difficulty in unlocking, thus balancing reliability and operability. Furthermore, the latch 61 rotates via the pivot 63, which reduces frictional wear between the latch 61 and the flip cover 20 compared to a fixed connection. The elastic force of the spring 64 allows the latch 61 to automatically reset when unlocked, preventing deformation or jamming caused by long-term use, extending the service life of the latch assembly 60, and reducing equipment maintenance costs.

[0033] Furthermore, the bean-feeding flip-top mechanism 1 also includes a hinge mechanism 30, which includes at least one bearing seat 14 disposed on the rear side of the chassis 10 and at least one connecting ear 32 disposed on the rear side of the flip-top 20. The connecting ear 32 and the bearing seat 14 are connected by a pin 31.

[0034] The bearing housing 14 provides stable support for the pin 31. The connecting ear 32 is connected to the bearing housing 14 via the pin 31, converting the rotation of the flip cover 20 into rolling friction between the pin 31 and the bearing housing 14, significantly reducing resistance. This makes it easier for users to open or close the flip cover 20, and even with frequent operation, there will be no feeling of jamming. On the other hand, the bearing housing 14 is fixed to the rear side of the chassis 10, and the connecting ear 32 is fixed to the rear side of the flip cover 20. The two are rigidly connected by the pin 31, forming a symmetrical force-bearing structure that can evenly distribute the weight of the flip cover 20 itself and the external force during operation. This design avoids the deformation or breakage problems caused by concentrated force in traditional simple hinges, ensuring that the flip cover 20 maintains stable rotational performance during long-term use and improving the durability of the mechanism. Furthermore, the combination of bearing housing 14, connecting ear 32 and pin 31 is a modular structure. During assembly, the connection can be completed simply by inserting the pin 31 into the corresponding hole, without the need for complicated adjustments. If wear occurs later, the pin 31 or bearing housing 14 can be replaced separately without replacing the entire flip cover 20 or chassis 10, thus reducing maintenance costs and difficulty.

[0035] Furthermore, the connecting ear 32 is U-shaped.

[0036] The U-shaped structure has two opposing sidewalls that wrap around the bearing housing 14 from both sides, significantly increasing the contact area with the bearing housing 14. When the flip cover 20 rotates, the force is evenly transmitted to the bearing housing 14 and the pin 31 through the two sidewalls, avoiding wear or breakage caused by stress concentration at a single contact point. On the other hand, the two sidewalls of the U-shaped connecting ear 32 form positioning grooves, allowing the bearing housing 14 to be directly embedded into the U-shaped grooves during assembly. This ensures that the connecting ear 32 and the hole position of the bearing housing 14 are aligned without repeated adjustments, significantly improving assembly efficiency. At the same time, the U-shaped structure restricts the horizontal sway of the connecting ear 32, ensuring that the pin 31 will not shift after insertion, further enhancing the stability of the hinge mechanism 30.

[0037] Furthermore, the groove 21 is recessed into the surface of the flip cover 20 facing the chassis 10, and the groove 21 has a bottom and a sidewall surrounding the bottom, through which the second vent 22 is opened.

[0038] The groove 21 is formed by the inward recess of the bottom surface of the flip cover 20. The dimensions of its bottom and sidewalls can be precisely designed according to the contour of the bean inlet cavity 11, ensuring that the periphery of the opening of the groove 21 can completely fit with the periphery of the opening of the bean inlet cavity 11 when closed. This recessed design avoids gaps caused by dimensional deviations of the groove 21, and also provides a stable foundation for the sealing effect of the sealing ring 40. The sealing ring 40 can be precisely pressed between the periphery of the groove 21 and the periphery of the bean inlet cavity 11, maximizing the sealing effect. On the other hand, the second vent 22 is opened on the sidewall of the groove 21, and the sidewall of the groove 21 corresponds to the sidewall of the bean inlet cavity 11. When the flip cover 20 is closed, the fit between the sidewall of the groove 21 and the sidewall of the bean inlet cavity 11 ensures that the second vent 22 is completely aligned with the first vent 13. This design avoids partial obstruction of the vent due to positional deviations, ensuring that silver powder and exhaust gas can pass through the vent in a straight line, reducing the risk of jamming or accumulation, and improving the efficiency of impurity removal. Furthermore, the groove 21 is recessed into the inside of the flip cover 20, and its bottom and sidewalls are integrally formed, resulting in stronger overall rigidity compared to grooves 21 that are spliced ​​later. When the flip cover 20 is frequently opened and closed or subjected to external forces, it is less prone to sidewall deformation, and can maintain the fitting precision with the bean inlet cavity 11 for a long time, ensuring the stability of ventilation and sealing performance.

[0039] Furthermore, the bean-feeding flip-top mechanism 1 also includes a sealing strip 50, which is installed on the chassis 10 and is disposed along the opening edge of the first vent 13.

[0040] The thin, light-colored silver coating produced during baking can become trapped in gaps at the vent joints if any exist. Over time, this accumulation can clog the vents and impurity removal. A sealing strip 50 is installed along the edge of the first vent 13. When the flip cover 20 is closed, the edge of the second vent 22 presses against the sealing strip 50, filling the gaps and ensuring that the silver coating can only enter the silver coating collection and exhaust module through the vents, preventing residue buildup. This design significantly reduces the frequency and difficulty of cleaning the vents, improving the ease of use of the equipment. On the other hand, the exhaust gases produced during baking contain small amounts of volatile substances. If these gases leak out through the vent gaps, they may produce odors or irritate the user. The elastic deformation of the sealing strip 50 completely seals the gaps at the vent joints, ensuring that all exhaust gases enter the silver coating collection and exhaust module, preventing pollution of the operating environment and improving user comfort and environmental friendliness.

[0041] This utility model also proposes a coffee roaster 100, such as Figure 8 , Figure 9 As shown, the coffee roaster 100 includes: Body 1001; The coffee roasting module, located inside the machine body 1001, is used for roasting coffee beans; and As described above, the base 10 of the bean feeding and flipping mechanism 1 is fixedly connected to the machine body 1001, and the bean inlet 12 of the bean feeding and flipping mechanism 1 is fluidly connected to the upper outlet of the bean drying module.

[0042] The specific structure of the bean feeding and flipping mechanism 1 is as described in the above embodiments. Since the coffee roaster 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0043] The flip-top 20 rotates smoothly via the hinge mechanism 30, and the locking assembly 60 ensures effortless opening and closing, allowing even novice users to quickly add coffee beans. Compared to traditional bean-feeding structures that require manual disassembly or complex operations, this mechanism significantly simplifies the process, making the roaster more accessible to home users or beginners. The sealed design of the mechanism reduces heat loss, enabling the roasting module to maintain a stable temperature field and preventing uneven roasting of coffee beans due to temperature fluctuations. Simultaneously, the smooth ventilation path ensures timely removal of silver shavings, preventing their accumulation from affecting heat transfer within the roasting chamber, further guaranteeing the roasting consistency of each batch of coffee beans and improving the quality stability of the final product. Silver shavings are efficiently removed through the vents, reducing residue in the bean-feeding chamber 11 and the vents; the openable design of the flip-top 20 also allows users to directly clean the inside of the bean-feeding chamber 11 without disassembling complex components. This design reduces the difficulty of equipment maintenance, minimizes malfunctions caused by residual impurities corroding parts, and extends the lifespan of the roaster.

[0044] Furthermore, the coffee roaster 100 also includes a shavings collection module and an air filtration module. Both the shavings collection module and the air filtration module are located inside the machine body 1001. The inlet of the shavings collection module is connected to the first vent 13 of the bean feeding flip-top mechanism 1, and is used to collect the coffee shavings discharged from the roasting module through the preset airflow path. The air filtration module is located behind the shavings collection module.

[0045] The silver residue collection module is connected to the first vent 13 and can collect the silver residue discharged from the ventilation path (e.g., through a filter or dust collection box), preventing the silver residue from scattering inside or outside the equipment with the airflow. Users only need to clean the collection module periodically to handle the silver residue, eliminating the need to wipe the inside of the equipment piece by piece, significantly reducing cleaning workload. At the same time, centralized collection also avoids blockages caused by silver residue accumulation in the pipes, ensuring the long-term smooth operation of the ventilation system. The air filtration module is located after the silver residue collection module and can purify the exhaust gas after silver residue separation (e.g., by adsorbing odors and harmful substances through an activated carbon filter).

[0046] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
