[0085] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0086] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0087] Example 1

[0088] like Figure 1-12 As shown, this embodiment provides an integrated roasting and grinding machine, mainly including a device body 1, a roasting mechanism 2, and a grinding mechanism 3. Both the roasting mechanism 2 and the grinding mechanism 3 are mounted on the device body 1. A controllable feeding channel 11 is provided between the roasting mechanism 2 and the grinding mechanism 3. Based on this, users only need one machine to complete the process from raw coffee beans to coffee powder, which not only reduces equipment configuration costs and space requirements but also makes it convenient and easy to use.

[0089] Furthermore, such as Figure 1-4As shown, the integrated roasting and grinding machine also includes a controller 4, and the roasting mechanism 2 and the grinding mechanism 3 are both electrically connected to the controller 4. The roasting mechanism 2 includes a storage bin 21, and the grinding mechanism 3 is equipped with a grinding section 31. The storage bin 21 and the grinding section 31 are connected via a conveying channel 11. Based on this structure, during use, the user only needs to put raw coffee beans into the storage bin 21 of the roasting mechanism 2, control the roasting parameters (such as temperature and time) through the controller 4, and then transport the roasted coffee beans to the grinding section 31 of the grinding mechanism 3 through the conveying channel 11. The controller 4 then controls the grinding mechanism 3 to grind the coffee beans to produce the desired coffee powder.

[0090] Furthermore, such as Figure 1 , Figure 4 , Figure 5 As shown, the feeding channel 11 is provided with a movable baffle 12 for opening / closing the feeding channel 11. The movable baffle 12 is connected to a first driving device 121, so that the first driving device 121 can control the movable baffle 12, thereby controlling the opening and closing state of the feeding channel 11. The first driving device 121 is electrically connected to the controller 4, so that the controller 4 can control the movement of the first driving device 121. This allows the movable baffle 12 to be interconnected and mutually influential with the roasting mechanism 2 and the grinding mechanism 3. For example, when the roasting mechanism 2 is working, the controller 4 controls the roasting parameter values. When the roasting mechanism 2 finishes working, the controller 4 controls the movable baffle 12 to move to open the feeding channel 11. When all the coffee beans fall into the grinding mechanism 3 (specifically the grinding section 31), the controller 4 controls the grinding mechanism 3 to grind the coffee beans.

[0091] As a preferred embodiment, the feed end of the conveying channel 11 is connected to the bottom wall of the storage hopper 21, and the movable baffle 12, when closed, can serve as at least part of the bottom wall of the storage hopper 21. By utilizing the gravity of the coffee beans themselves, most of the coffee beans can be output from the storage hopper 21 to the next operating unit. Then, using the cold air provided by the roasting mechanism 2, the remaining coffee beans can be output to the next operating unit, further simplifying the device structure.

[0092] In addition, a sealing gasket 13 is provided between the movable baffle 12 and the storage bin 21, which can effectively prevent heat loss in the storage bin 21 during baking, so as to ensure the baking effect and save energy.

[0093] As a preferred option, such as Figure 1As shown, the movable baffle 12 has a protrusion 122 on the side facing the storage bin 21. The cross-sectional shape of the protrusion 122 is consistent with the cross-sectional shape of the conveying channel 11 on the bottom wall of the storage bin 21. Therefore, when the movable baffle 12 is in the closed state, the protrusion 122 is nested at the opening of the conveying channel 11 on the bottom wall of the storage bin 21. At this time, the sealing gasket 13 is arranged around the outer side of the protrusion 122 and the inner side of the conveying channel 11.

[0094] In this embodiment, the cross-sectional area of ​​the protrusion 122 is preferably set to half the area of ​​the bottom wall of the storage bin 21.

[0095] Furthermore, a rotating shaft 123 is provided on the device body 1 at the position corresponding to the movable baffle 12. The movable baffle 12 is swayably mounted on the rotating shaft 123. The rotation of the rotating shaft 123 drives the movable baffle 12 to sway. In this embodiment, the first driving device 121 is a synchronous motor. The synchronous motor is connected to the rotating shaft 123. The rotation of the synchronous motor drives the rotation of the rotating shaft 123. At the same time, the synchronous motor is also electrically connected to the controller 4. By controlling the controller 4, the synchronous motor can be controlled.

[0096] As a preferred embodiment, a position sensor 124 is also provided on the device body 1 at the position corresponding to the movable baffle 12. The position sensor 124 is electrically connected to the controller 4 and is used to sense the swing amplitude of the movable baffle 12. More preferably, the swing amplitude is set to 30-60°. By controlling the swing amplitude of the movable baffle 12, the output amount of coffee beans in the storage bin 21 can be controlled. Based on this, for example, the position sensor 124 can be set as a position switch. That is, after the user determines the output amount of coffee beans, when the movable baffle 12 is in position, the position switch (i.e., the position sensor 124) senses it and feeds it back to the controller 4. The controller 4 then controls the first drive device 121 (such as a synchronous motor) to stop rotating, thereby putting the material conveying channel 11 in the corresponding open state. In addition, the position sensor 124 in this embodiment should also meet the requirements of being able to detect the position information of the movable baffle 12 when it is in a fully closed state and a fully open state and feed it back to the controller 4.

[0097] As a preferred option, such as Figure 1 , Figure 8As shown, a torsion spring 125 is provided between the movable baffle 12 and the rotating shaft 123. One end of the torsion spring 125 abuts against the side of the movable baffle 12 facing away from the protrusion 122. The torsion spring 125 can both provide overload protection against the output of the synchronous motor when the movable baffle 12 is in the closed state, and also allow the protrusion 122 to have a certain amount of elastic displacement to avoid mechanical damage to the structure caused by excessive instantaneous load. In addition, the torsion spring 125 also has a reset function. The specific reset process is as follows: since one end of the torsion spring 125 abuts against the side of the movable baffle 12 facing away from the protrusion 122, when the first driving device 121 (such as the rotating engagement teeth of the synchronous motor) disengages, the torsion spring 125 will continuously provide an elastic force to close the movable baffle 12, thereby keeping the movable baffle 12 in the closed state and closing the material conveying channel 11.

[0098] The storage bin 21 is provided with a hot air inlet 211, and the device body 1 is provided with an air inlet 14 that communicates with the outside. The hot air inlet 211 is connected to the air inlet 14. In this embodiment, the air inlet 14 is located on the back of the housing of the device body 1.

[0099] Furthermore, a hot air forming chamber 22 is provided between the hot air inlet 211 and the air inlet 14; a heating element 221 is provided inside the hot air forming chamber 22, and the heating element 221 is electrically connected to the controller 4. The controller 4 can control the operation of the heating element 221 to control the roasting temperature, time, etc. of the coffee beans.

[0100] In this embodiment, as Figure 4 , Figure 9 As shown, the heating element 221 is horn-shaped, with its narrow end connected to the hot air inlet 211. A blower 23 is located at the flared end of the heating element 221, and the blower 23 is electrically connected to the controller 4. Therefore, designing the heating element 221 in a horn shape facilitates both the absorption of more cold air from the outside and the concentrated delivery of hot air.

[0101] As a preferred embodiment, a heat insulation cover 24 is also provided on the device body at the position corresponding to the heating element 221. The heating element 221 is fixedly installed in the hot air forming chamber 22 by the heat insulation cover 24. The heat insulation cover 24 further facilitates the concentrated transfer of heat from the heating element 221 to the storage hopper 21, and also prevents the heat generated by the heating element 221 from affecting other electrical components inside the device body 1, effectively improving the safety and reliability of the device.

[0102] In addition, such as Figure 4 , Figure 7 As shown, an air guide hood 25 is provided inside the storage bin 21 at the position corresponding to the hot air inlet 211. The side of the air guide hood 25 has several air guide holes 251. In this embodiment, a gap is left between the outer side of the air guide hood 25 and the inner side of the storage bin 21. Therefore, the airflow emitted from the hot air forming chamber 22 first passes through this gap, and then enters through the air guide holes 251 on the air guide hood 25 and acts on the coffee beans in the storage bin 21. This allows the airflow to act more evenly on the coffee beans in the storage bin 21, ensuring roasting quality.

[0103] As a preferred embodiment, each of the air guide holes 251 is uniformly arranged along the circumference of the air guide shroud 25, and at least some of the air guide holes 251 are inclined along the axial direction of the air guide shroud 25, so that the airflow can form a swirling flow after passing through the air guide holes 251, thereby further improving the baking quality.

[0104] In this embodiment, as Figure 1-6 As shown, an exhaust vent 212 is also provided on the storage bin 21, and a bean hull storage and retrieval device 26 is detachably provided at the exhaust vent 212; the bean hull storage and retrieval device 26 is provided so that: in the roasting state, the bean hulls of coffee beans can be collected in the bean hull storage and retrieval device 26 by the airflow, so as to facilitate centralized processing.

[0105] As a preferred embodiment, the bean curd skin storage and retrieval device 26 includes a bean curd skin box 261 that can rotate relative to the storage bin 21. The bean curd skin box 261 is provided with an exhaust port 2611 and a filter screen 262 is provided at the exhaust port 2611, so that airflow can flow out through the filter screen 262, while the bean curd skin is blocked by the filter screen 262 in the bean curd skin box 261 for collection and processing.

[0106] As a preferred embodiment, the opening edge of the exhaust port 2611 is provided with a U-shaped groove, and the filter screen 262 is detachably embedded in the U-shaped groove; Figure 4-6 As shown, the filter screen 262 is inserted into the opening of the U-shaped groove and placed in the U-shaped groove to form a drawer-type installation method, which makes the installation and use of the filter screen 262 more convenient, and also facilitates the cleaning of the bean curd box 261.

[0107] Furthermore, the height of the connection point between the bean curd box 261 and the exhaust vent 212 is higher than the height of the bottom of the U-shaped groove; for example... Figure 3 , 5As shown in Figure 6, the opening of the U-shaped groove faces upward, so that the exhaust port 2611 of the bean skin box 261 faces the side of the device body 1. The orientation of the exhaust port 2611 can be changed by rotating the bean skin box 261, so that the user can adjust it according to their own needs. In addition, the bottom of the U-shaped groove is lower than the position where the bean skin box 261 connects with the exhaust port 212, which can further facilitate the collection of coffee bean skins and effectively prevent bean skins from flowing back into the storage bin 21.

[0108] As a preferred embodiment, the storage bin 21 further includes a transparent baking cover 27, which is at least partially exposed on the device body 1. In this embodiment, the baking cover 27 is a cylindrical glass cover, such as... Figure 7 As shown, one end of the baking cover 27 is inserted into the top of the device body 1 and abuts against the air guide cover 25; the bean curd skin storage and retrieval device 26 is detachably disposed at the other end of the baking cover 27.

[0109] As a preferred embodiment, a temperature sensor 28 is installed in the storage bin 21, and the temperature sensor 28 is electrically connected to the controller 4; by setting the temperature sensor 28, the baking temperature in the storage bin 21 can be fed back to the controller 4, so that the user can better control the baking depth.

[0110] Furthermore, the baking and grinding integrated machine is also equipped with a status indicator light 213. The status indicator light 213 can be set on the device body 1 or on the storage bin 21, such as at the position corresponding to the baking cover 27, so that the light of the status indicator light 213 can penetrate into the baking cover 27 to bring users a different visual experience. In addition, the status indicator light 213 is electrically connected to the controller 4, so that the status indicator light 213 emits different colors of light according to the different baking depths.

[0111] like Figure 11 As shown, in this embodiment, the grinding unit 31 includes an upper blade 311 and a lower blade 312, and a grinding gap is formed between the upper blade 311 and the lower blade 312. The size of the grinding gap is adjustable. Users can adjust the grinding gap according to their preferences to obtain coffee powder of different coarseness. That is, this structure can meet the different taste needs of different users.

[0112] As a preferred embodiment, the grinding mechanism 3 further includes a drive mechanism 32 for driving the grinding part 31 to move, and the drive mechanism 32 is electrically connected to the controller 4; in this embodiment, the drive mechanism 32 is a motor.

[0113] Furthermore, the drive mechanism 32 is located above the grinding section 31; the output shaft of the drive mechanism 32 passes axially through the upper cutter head 311 and is connected to the lower cutter head 312. The upper cutter head 311 is threadedly connected to the device body 1 so that the upper cutter head 311 can move along its own axial direction, thereby realizing the adjustment of the grinding gap.

[0114] As a preferred embodiment, the device body 1 is provided with a plurality of retractable push rods 33, and the upper cutter disc 311 is provided with a plurality of recesses 34; when the upper cutter disc 311 is connected to the device body 1 so that the grinding gap reaches a set value, each push rod 33 and each recess 34 respectively cooperate to form a rotation limit on the upper cutter disc 311.

[0115] Furthermore, a first elastic element 331 is sleeved on the push rod 33, and the first elastic element 331 pushes the push rod 33 against the upper cutter head 311; the end of the push rod 33 that contacts the recessed portion 34 is a rounded end, and the shape of the recessed portion 34 matches the rounded end.

[0116] As a preferred embodiment, the baking and grinding integrated machine also includes an adjustment plate 35, which is detachably and fixedly connected to the upper blade disc 311. The adjustment plate 35 is threadedly connected to the machine body 1, and the recessed portion 34 is located on the upper end face of the adjustment plate 35. Designing the upper blade disc 311 and the adjustment plate 35 as separate components facilitates the maintenance and replacement of the device, avoids the need to replace the entire part due to damage to any function of the upper blade disc 311 or the adjustment plate 35, and reduces operating costs.

[0117] Furthermore, the outer wall of the adjustment disc 35 is evenly distributed with limit scale lines, and the device body 1 is provided with marking lines that correspond to the limit scale lines, so that the user can adjust the grinding fineness according to the alignment of the marking lines with the limit scale lines, thereby making the adjustment of the grinding gap more convenient, quick and intuitive.

[0118] As a preferred embodiment, a powder cover 36 is also provided on the device body 1 at the position corresponding to the grinding section 31, and the grinding gap falls within the coverage area of ​​the powder cover 36. Figure 11 As shown, the powder cover 36 is flared, and the flared end of the powder cover 36 is the discharge port of the device body 1.

[0119] In addition, a flat portion is provided on the output shaft of the drive mechanism 32, and a flat hole is provided on the lower blade disc 312; the lower blade disc 312 is fitted onto the flat portion through the flat hole to form a circumferential limit on the lower blade disc 312.
