Description

Technical Field

[0001] The utility model relates to the technical field of coffee making equipment, in particular to a discharging device, a bean grinder and a coffee machine. Background Art

[0002] Coffee as a beverage has penetrated into people's lives. With the improvement of people's consumption level, the requirements for coffee quality are getting higher and higher. More and more people choose coffee drinks that are mixed, ground and brewed on the spot, rather than pre-made coffee powder. Different styles of coffee drinks prepared on site require different ratios of coffee beans and water. At present, the measurement of coffee beans is usually done by the barista manually scooping the coffee beans and then putting them on an electronic scale for weighing. This manual weighing method has the problem of inaccurate weighing at one time and requiring multiple scooping, resulting in a low efficiency of the coffee bean measuring process.

[0003] In order to improve the efficiency of coffee bean measurement, an automatic coffee bean dispensing device has emerged. However, the existing automatic coffee bean dispensing device has low bean dispensing accuracy and is difficult to accurately dispense the required amount of coffee beans, which affects the taste of the prepared coffee. Utility Model Content

[0004] In view of this, the utility model provides a discharging device to solve the problem of low bean discharging accuracy of existing automatic coffee bean discharging devices.

[0005] In a first aspect, the utility model provides a discharging device, comprising:

[0006] Storage silos;

[0007] A frame, connected to the storage bin;

[0008] A first discharging component is rotatably disposed in the frame, and the first discharging component is provided with a plurality of first containing grooves;

[0009] A second discharging component is rotatably disposed in the frame, the second discharging component is coaxially disposed with the first discharging component, the second discharging component is provided with a plurality of second containing grooves, and the volume of the second containing grooves is smaller than the volume of the first containing grooves;

[0010] A driving assembly is arranged on the frame, and the driving assembly drives the first discharging component and the second discharging component to rotate around their own axes respectively.

[0011] Beneficial effect: The discharging device provided in this embodiment is provided with a second discharging component on the basis of the first discharging component. The second discharging component is coaxially arranged with the first discharging component to simplify the layout, making the structure of the discharging device compact and the volume reduced, and the volume of the second containing groove of the second discharging component is smaller than the volume of the first containing groove of the first discharging component, so the single discharging amount of the second discharging component is smaller than the single discharging amount of the first discharging component. When discharging, the material is first discharged through the first processing component, and then the second processing component is used to increase the discharging amount by a small amount, so that the total discharging amount gradually approaches the required discharging amount. When the discharging device of the utility model is applied to a coffee machine, the total amount of discharging can be gradually approached to the required total amount of coffee beans, and the automatic and precise adjustment of the coffee bean discharging can be realized, avoiding the problem of inaccurate discharging amount due to excessive single discharging amount. The discharging device provided in this embodiment realizes both fast and accurate discharging, can improve the efficiency of measuring coffee beans, and thus ensure the quality of coffee blending.

[0012] In an optional embodiment, the first discharging component and the second discharging component rotate in opposite directions.

[0013] Beneficial effects: The configuration of the driving assembly can be optimized, the number of components of the driving assembly can be reduced, the structure of the discharging device can be simplified, and the manufacturing cost can be reduced.

[0014] In an optional embodiment, a flow limiting mechanism is further included, and the flow limiting mechanism is arranged on the frame, and the flow limiting mechanism is used to block the material outside the first containing groove or the second containing groove.

[0015] Beneficial effect: By setting a current limiting mechanism, the single discharge volume of the first discharge component and the second discharge component is equal to the volume of the first accommodating groove and the second accommodating groove, so as to ensure the accuracy of the discharge.

[0016] In an optional embodiment, two groups of the flow limiting mechanisms are provided, and the two groups of the flow limiting mechanisms are respectively provided close to the first receiving tank and the second receiving tank containing the material, and the two groups of the flow limiting mechanisms are respectively located downstream of the first receiving tank and the second receiving tank containing the material in their respective rotation directions.

[0017] Beneficial effect: When the first discharging component and the second discharging component rotate, the coffee beans outside the first accommodating groove and the second accommodating groove can be blocked by the current limiting mechanism, thereby improving the discharging accuracy.

[0018] In an optional embodiment, the flow limiting mechanism includes a flow limiting plate and an elastic member, one end of the flow limiting plate is rotatably connected to the frame, and the other end is arranged close to the edge of the first containing tank or the second containing tank containing the material;

[0019] The side of the limiting plate facing away from the rotation direction of the first discharging component or the second discharging component is the back side of the limiting plate, one end of the elastic member is connected to the inner wall of the frame, and the other end is connected to the back side of the limiting plate, or one of the inner wall of the frame and the back side of the limiting plate is connected to one end of the elastic member, and the other is spaced apart from the other end of the elastic member. After the limiting plate swings with the first discharging component or the second discharging component, the other of the inner wall of the frame and the back side of the limiting plate abuts against the other end of the elastic member.

[0020] Beneficial effect: the flow limiting plate can block excess coffee beans during the rotation of the first discharging component and the second discharging component, and the elastic member can keep the other end of the flow limiting plate at the edge of the first receiving groove or the second receiving groove. When the groove wall of the first receiving groove or the second receiving groove in the downstream direction of rotation contacts the flow limiting plate, the rotation of the first discharging component and the second discharging component will push the flow limiting plate to rotate and compress the elastic member. The material overflowing from the first receiving groove or the second receiving groove will be separated from the corresponding receiving groove under the action of the flow limiting plate, and the first discharging component and the second discharging component will continue to rotate to output the material. By setting the flow limiting plate, the discharge of material exceeding the capacity of the receiving groove can be effectively prevented, and at the same time, it will not interfere with the rotation of the first discharging component and the second discharging component.

[0021] In an optional embodiment, a limiting mechanism is further included, wherein the limiting mechanism is disposed on the frame, and the limiting mechanism is used to limit one of the first discharging component and the second discharging component from rotating with the other one.

[0022] Beneficial effect: When the driving component drives the first discharging component or the second discharging component, under the action of friction, one of the first discharging component and the second discharging component is easy to rotate with the other, and the above-mentioned following movement can be limited by setting a limiting mechanism.

[0023] In an optional embodiment, the limiting mechanism includes a limiting plate, which is arranged close to the side of the current limiting plate away from the elastic member, and at least part of the structure of the end of the current limiting plate away from its rotating shaft enters the first receiving groove or the second receiving groove. When the first discharging part and the second discharging part rotate in reverse, the current limiting plate abuts against the edge of the first receiving groove or the second receiving groove in the downstream direction of rotation, and the limiting plate abuts against the current limiting plate.

[0024] Beneficial effect: Because the first discharging component and the second discharging component rotate in opposite directions, when one of them rotates forward, the other may rotate reversely due to friction. At this time, the current limiting plate will abut against the downstream edge of the first accommodating groove or the second accommodating groove in the rotation direction to prevent it from rotating reversely.

[0025] In an optional embodiment, the side wall and the bottom of the second accommodating groove are transitioned through an arc structure.

[0026] Beneficial effect: The shape of the second accommodating groove is closer to the shape of the material, such as the shape of a coffee bean. The second accommodating groove can more easily accommodate a single material, such as a coffee bean, and after accommodating a single coffee bean, the gap between the coffee bean and the second accommodating groove can be minimized, thereby accurately controlling the single discharge amount of the second discharging component and improving the discharge accuracy.

[0027] In an optional embodiment, the side wall of the second containing groove located upstream in the rotation direction of the second discharging component is smoother than the side wall of the second containing groove located downstream in the rotation direction of the second discharging component.

[0028] Beneficial effects: The above arrangement can accelerate the falling of materials and increase the discharging speed, while enabling the limiting plate to firmly abut against the side wall downstream of the second discharging component in the rotation direction, thereby preventing the second discharging component from rotating with the first discharging component.

[0029] In an optional embodiment, the side wall of the second accommodating groove located upstream in the rotation direction of the second discharging component smoothly transitions to the peripheral side surface of the second discharging component.

[0030] Beneficial effect: It is convenient for materials (such as coffee beans) to slide into the second containing groove, avoiding the situation of beans being stuck.

[0031] In an optional embodiment, the interior of the frame is divided into a first accommodating chamber and a second accommodating chamber, and the first discharge component and the second discharge component are respectively arranged in the first accommodating chamber and the second accommodating chamber.

[0032] Beneficial effect: It avoids the mutual interference and squeezing of materials (coffee beans) between the first discharging component and the second discharging component, thereby improving the reliability of the mechanism.

[0033] In a second aspect, the utility model further provides a bean grinder, comprising: a bean grinding device and the above-mentioned discharge device, wherein the discharge device is connected to the bean grinding device.

[0053] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0054] Combine the following Figures 1 to 7 , describing the embodiments of the discharging device, bean grinder and coffee machine of the utility model.

[0055] According to an embodiment of the utility model, on the one hand, a discharging device is provided, including a storage bin 1, a frame 2, a first discharging component 3, a second discharging component 4 and a driving assembly 5, the frame 2 is connected to the storage bin 1; the first discharging component 3 is rotatably arranged in the frame 2, and the first discharging component 3 is provided with a plurality of first accommodating grooves 31; the second discharging component 4 is rotatably arranged in the frame 2, and the second discharging component 4 is provided with a plurality of second accommodating grooves 41, and the volume of the second accommodating grooves 41 is smaller than the volume of the first accommodating grooves 31; the driving assembly 5 is arranged on the frame 2, and the driving assembly 5 drives the first discharging component 3 and the second discharging component 4 to rotate around their own axes respectively.

[0056] The discharging device provided in the present embodiment is provided with a second discharging component 4 on the basis of the first discharging component 3. The second discharging component 4 is coaxially arranged with the first discharging component 3 to simplify the layout, so that the structure of the discharging device is compact and the volume is reduced. When discharging, the material (such as coffee beans) in the storage bin 1 will enter the frame 2 and the first receiving groove 31 under the action of gravity. The driving component 5 first drives the first discharging component 3 to rotate. During the rotation process, the coffee beans in the first receiving groove 31 will fall and be discharged due to gravity. Since the volume of the first receiving groove 31 is large, the single discharging amount of the first discharging component 3 is large, which can The total amount of discharge is quickly close to the required total amount of coffee beans; when the total amount of discharge is close to the required total amount of coffee beans, the driving assembly 5 controls the first discharge component 3 to stop rotating, and the second discharge component 4 is rotated. Similarly, during the rotation process, the coffee beans in the second accommodating groove 41 will fall due to gravity. Since the volume of the second accommodating groove 41 is smaller than the volume of the first accommodating groove 31, the single discharge amount of the second discharge component 4 is small, and the total amount of coffee beans required can be gradually approached on the existing total amount of discharge, avoiding the problem that the total amount of coffee beans required cannot be approached regardless of whether the discharge is repeated because the single discharge amount is too large. The discharge device provided in this embodiment realizes fast and accurate automatic discharge, improves the efficiency of coffee bean measurement, and ensures the quality of coffee preparation.

[0057] The storage bin 1 is provided with a first discharge port and a first feed port, and the first discharge port and the first feed port are respectively arranged at two ends of the storage bin 1, specifically at the upper and lower ends. The material can enter the storage bin 1 through the first feed port, and then enter the frame 2 through the first discharge port. The utility model does not limit the shape of the storage bin 1. In this embodiment, the side wall of one end of the storage bin 1 connected to the frame 2 has an inclination angle, which is convenient for the coffee beans to fall with gravity and avoid the coffee beans from getting stuck.

[0058] The frame 2 is provided with a second feed port and a second discharge port, the second feed port is connected with the first discharge port, and the material is transmitted by the rotation of the first discharge component 3 and the second discharge component 4, and then discharged from the frame 2 through the second discharge port. In this embodiment, the storage bin 1 is arranged above the frame 2.

[0059] Furthermore, the interior of the frame 2 is divided into a first accommodating chamber 21 and a second accommodating chamber 22, and the first discharging component 3 and the second discharging component 4 are respectively arranged in the first accommodating chamber 21 and the second accommodating chamber 22 to avoid mutual interference and squeezing of materials (coffee beans) between the first discharging component 3 and the second discharging component 4.

[0060] Specifically, a partition 23 is provided in the frame 2, and the partition 23 is arranged perpendicular to the rotation axis of the first discharging component 3 and the second discharging component 4. The partition 23 divides the frame 2 into a first accommodating chamber 21 and a second accommodating chamber 22. The first discharging component 3 and the second discharging component 4 are respectively arranged in the first accommodating chamber 21 and the second accommodating chamber 22, so that the first discharging component 3 and the second discharging component 4 can operate independently without affecting each other, thereby improving the reliability of the mechanism.

[0061] The utility model does not limit the specific shape of the first discharging component 3. Figure 3 As shown, in the present embodiment, the first discharging component 3 is gear-shaped, one end face of the first discharging component 3 faces the partition plate 23, the other end face of the first discharging component 3 faces the inner wall of the frame 2, and the rotation axis of the second discharging component 4 is the axis of the cylinder. The first discharging component 3 includes a plurality of gear teeth 32, and the ends of the gear teeth 32 are arc-shaped to ensure smooth rotation. At the same time, the ends of the arc-shaped gear teeth 32 can avoid damage to the material; a plurality of gear teeth 32 are evenly spaced around the rotation axis of the first discharging component 3, and a first accommodating groove 31 is formed between adjacent gear teeth 32. The volume of the first accommodating groove 31 is adjusted by changing the size or spacing distance of the gear teeth 32, or the volume of the first accommodating groove 31 is adjusted by changing the number of gear teeth 32, thereby changing the single discharging amount of the first discharging component 3.

[0062] In other embodiments, the first discharging component 3 may also be a cylindrical structure, and the first accommodating grooves 31 are arranged at intervals on the peripheral side surface of the first discharging component 3 .

[0063] In this embodiment, there is no restriction on the number of the first containing grooves 31. In this embodiment, four first containing grooves 31 are provided, and the capacity of each first containing groove 31 is the same, which can ensure that the coffee beans in the first containing groove 31 can be poured out each time the bean-discharging machine is rotated to discharge the beans, thereby preventing the coffee beans from being left in the first containing groove 31, thereby causing inaccurate bean discharging and affecting the bean discharging efficiency.

[0064] The utility model does not limit the amount of coffee beans that the first accommodating groove 31 can hold. In this embodiment, the amount of coffee beans that the first accommodating groove 31 can hold is about 1g, so as to achieve fast coffee bean output. In other embodiments, the amount of coffee beans that the first accommodating groove 31 can be set as needed.

[0065] like Figure 5-Figure 7 As shown, the utility model does not limit the specific shape of the second discharging component 4. In the present embodiment, the second discharging component 4 is cylindrical, one end face of the second discharging component 4 faces the partition 23, and the other end face of the second discharging component 4 faces the inner wall of the frame 2. The rotation axis of the second discharging component 4 is the axis of the cylinder, and the second accommodating grooves 41 are arranged at intervals on the peripheral side of the second discharging component 4.

[0066] The utility model does not limit the number of the second containing grooves 41. In the present embodiment, four second containing grooves 41 are provided, the capacity of each second discharging component 4 is the same, and the four second containing grooves 41 are evenly arranged around the rotation axis of the second discharging component 41, which can ensure that the material in the second containing groove 41 can be poured out each time the material is rotated to discharge, thereby avoiding the problem of inaccurate coffee beans being left in the second containing groove 41 and causing coffee beans to be discharged.

[0067] In this embodiment, the axial directions of the first discharging component 3 and the second discharging component 4 are arranged in parallel.

[0068] In other embodiments, the second discharging component 4 may also be a gear-shaped structure.

[0069] Furthermore, if Figure 6 As shown, the side wall and the bottom of the second receiving groove 41 are transitioned through an arc structure, so that the shape of the second receiving groove 41 is closer to the shape of a single material (such as coffee beans), and the second receiving groove 41 can more easily accommodate a single material, and after accommodating a single material, the gap between the material and the second receiving groove 41 can be minimized, thereby accurately controlling the single discharge amount of the second discharge component 4.

[0070] Furthermore, the side wall of the second accommodating groove 41 located upstream in the rotation direction of the second discharging component 4 smoothly transitions to the peripheral side surface of the second discharging component 4, which facilitates the coffee beans to slide into the second accommodating groove 41 and avoids the situation of beans getting stuck.

[0071] The utility model does not limit the size of the second receiving groove 41. In the present embodiment, the length dimension of the second receiving groove 41 is 13 mm, the width dimension is 6 mm, and the depth dimension is 5 mm, so that the second receiving groove 41 is closer to the outer dimensions of a single material (such as coffee beans) to improve the accuracy of the beans discharged from the second receiving groove 41. In other embodiments, the size of the second receiving groove 41 should be set according to the specific type of the material.

[0072] Furthermore, the rotation directions of the first discharging component 3 and the second discharging component 4 are opposite, which can optimize the configuration of the driving assembly 5 and reduce the number of components of the driving assembly 5 .

[0073] Specifically, the driving assembly 5 includes a driving member 51 and two one-way bearings 52. The first discharging component 3 and the second discharging component 4 are respectively connected to the driving shaft of the driving member 51 through a one-way bearing 52, and the rotation directions of the two one-way bearings 52 are opposite. When the driving member 51 rotates in one direction, it can only drive one of the first discharging component 3 or the second discharging component 4 to rotate. The above arrangement can achieve the purpose of one driving member 51 driving the first discharging component 3 and the second discharging component 4 to rotate, thereby reducing the number of driving members 51 and reducing manufacturing costs.

[0074] In other embodiments, the driving assembly 5 may also include two driving members 51, which respectively drive the first discharging member 3 and the second discharging member 4. In this case, the rotation directions of the first discharging member 3 and the second discharging member 4 may be the same or opposite.

[0075] The present invention does not limit the specific type of the driving component 51. In the present embodiment, the driving component 51 is a servo motor, which can be precisely controlled according to the signal. In other embodiments, the driving component 51 can also be a stepping motor.

[0076] Furthermore, the discharging device also includes a flow limiting mechanism 6, which is arranged on the frame 2. The flow limiting mechanism 6 is used to block the material outside the first receiving groove 31 or the second receiving groove 41, so that the single discharging amount of the first discharging component 3 and the second discharging component 4 is the volume of the first receiving groove 31 and the second receiving groove 41, so as to ensure the accuracy of the discharging.

[0077] Specifically, two groups of flow limiting mechanisms 6 are provided, and the two groups of flow limiting mechanisms 6 are respectively provided near the first receiving groove 31 and the second receiving groove 41 containing the material, and the two groups of flow limiting mechanisms 6 are respectively located downstream of the first receiving groove 31 and the second receiving groove 41 containing the material in the respective rotation directions. When the first discharging component 3 and the second discharging component 4 rotate, the coffee beans outside the first receiving groove 31 and the second receiving groove 41 can be blocked by the flow limiting mechanisms 6, so that the excess materials overflowing from the first receiving groove 31 and the second receiving groove 41 will not continue to rotate with the first discharging component 3 and the second discharging component 4, and then fall and be discharged.

[0078] Specifically, the flow limiting mechanism 6 includes a flow limiting plate 61 and an elastic member 62, one end of the flow limiting plate 61 is rotatably connected to the frame 2, and the other end is arranged near the edge of the first accommodating groove 31 or the second accommodating groove 41 containing the material; the side of the flow limiting plate 61 facing away from the rotation direction of the first discharging component 3 or the second discharging component 4 is the back side of the flow limiting plate 61, one end of the elastic member 62 is connected to the inner wall of the frame 2, and the other end is connected to the back side of the flow limiting plate 61, or one of the inner wall of the frame 2 and the back side of the flow limiting plate 61 is connected to one end of the elastic member 62, and the other is spaced apart from the other end of the elastic member 62. After the flow limiting plate 61 swings with the first discharging component 3 or the second discharging component 4, the inner wall of the frame 2 and the other of the back side of the flow limiting plate 61 abut against the other end of the elastic member 62.

[0079] The limiting plate 61 can block excess coffee beans during the rotation of the first discharging component 3 and the second discharging component 4, and the elastic member 62 can keep the other end of the limiting plate 61 at the edge of the first receiving groove 31 or the second receiving groove 41. When the upstream groove wall of the first receiving groove 31 or the second receiving groove 41 in the rotation direction contacts the limiting plate 61, the rotation of the first discharging component 3 and the second discharging component 4 will push the limiting plate 61 to rotate and compress the elastic member 62, thereby blocking the coffee beans outside the first receiving groove 31 and the second receiving groove 41 and avoiding interfering with the rotation of the first discharging component 3 and the second discharging component 4.

[0080] The material of the flow limiting plate 61 is not specifically limited in this embodiment. In this embodiment, the flow limiting plate 61 is made of an elastic metal material, which has good corrosion resistance, high structural strength, is not easy to be damaged, and prolongs the service life of the flow limiting plate 61. In other embodiments, the flow limiting plate 61 can also be made of an elastic plastic material.

[0081] The utility model does not limit the specific type of the elastic member 62. In this embodiment, the elastic member 62 is a spring, such as Figure 4 As shown, a slot 611 is provided on one side of the current limiting plate 61, one end of the elastic member 62 is engaged with the slot 611, and the other end of the elastic member 62 is spaced from the inner wall of the frame 2. In other embodiments, the elastic member 62 may also be a torsion spring.

[0082] Furthermore, the discharging device further comprises a limiting mechanism 7, which is arranged on the frame 2, and is used for limiting one of the first discharging component 3 and the second discharging component 4 from rotating with the other one.

[0083] When the driving component 5 drives the first discharging component 3 or the second discharging component 4, one of the one-way bearings 52 rotates in the same direction as the driving component 5, but the friction force in the one-way bearing 52 may still drive the first discharging component 3 or the second discharging component 4 connected to the one-way bearing 52 to rotate, resulting in inaccurate discharging. The limiting mechanism 7 is used to limit one of the first discharging component 3 and the second discharging component 4 from rotating with the other.

[0084] Specifically, the limiting mechanism 7 includes a limiting plate 71, which is arranged near the side of the limiting plate 61 away from the elastic member 62. At least part of the structure of the end of the limiting plate 61 away from its rotation axis enters the first accommodating groove 31 or the second accommodating groove 41. When the first discharge component 3 and the second discharge component 4 rotate in reverse, the limiting plate 61 abuts against the inner side of the edge downstream of the first accommodating groove 31 or the second accommodating groove 41 in the rotation direction, and the limiting plate 71 abuts against the limiting plate 61. Because the first discharge component 3 and the second discharge component 4 rotate in opposite directions, when one of them rotates forward, the other may rotate in reverse due to friction. At this time, the limiting plate 61 abuts against the inner side of the edge downstream of the first accommodating groove 31 or the second accommodating groove 41 in the rotation direction to prevent it from rotating in reverse.

[0085] Furthermore, the side wall of the second containing groove 41 located upstream of the second discharging member 4 in the rotation direction (CC') is smoother than the side wall of the second containing groove 41 located downstream of the second discharging member 4 in the rotation direction. Figure 7 As shown, the flow limiting plate 61 can be stably abutted against the side wall downstream of the second discharging component 4 in the rotation direction, preventing the second discharging component 4 from rotating with the first discharging component 3 .

[0086] Specifically, the end surface of the limiting plate close to one end of the first discharging component 3 or the second discharging component 4 is inclined toward the rotation direction of the first discharging component 3 or the second discharging component 4, so as not to affect the rotation of the first discharging component 3 or the second discharging component 4 when the first discharging component 3 or the second discharging component 4 rotates to discharge materials, and at the same time prevents scratches and damage to the first discharging component 3 or the second discharging component 4, and can also prevent the other from following the rotation.

[0087] According to an embodiment of the present invention, on the other hand, a bean grinder is provided, comprising a bean grinding device and the above-mentioned discharging device, wherein the discharging device is connected to the bean grinding device. By providing the above-mentioned discharging device, accurate and fast automatic bean discharging can be achieved, thereby improving the automation of the bean grinder and speeding up the efficiency of bean grinding.

[0088] According to an embodiment of the utility model, on the other hand, a coffee machine is provided, comprising a weighing device and the above-mentioned discharging device, wherein the discharging device is connected to the weighing device. The above-mentioned discharging device can realize accurate and fast automatic discharging of beans, improve the efficiency and quality of coffee preparation, and at the same time improve the automation degree of the coffee machine, saving manpower.

[0089] The discharging process of the coffee machine of this embodiment is described in detail below in conjunction with the accompanying drawings:

[0090] When the coffee machine is discharging, the driving member 51 drives the first discharging member 3 to rotate, and the coffee beans in the first receiving groove 31 will fall from the second discharging port of the frame 2 as the first discharging member 3 rotates. During the rotation, the limiting plate 61 will block the coffee beans outside the first receiving groove 31 from falling, so as to ensure the accurate single discharging amount of the first discharging member 3; when the first discharging member 3 rotates to discharge, the one-way bearing 52 connected to the second discharging member 4 and the limiting plate 61 arranged near the second discharging member 4 will prevent the second discharging member 4 from rotating with the first discharging member 3.

[0091] When the total discharge amount of the first discharge component 3 is close to the required total amount of coffee beans, the driving member 51 stops driving the first discharge component 3 to rotate, and the driving member 51 starts to reverse to drive the second discharge component 4 to rotate, and the coffee beans in the second receiving groove 41 will fall from the second discharge port of the frame 2 as the second receiving groove 41 rotates. During the rotation of the second discharge component 4, the limiting plate 61 will block the coffee beans outside the second receiving groove 41 from falling, so as to ensure the accurate single discharge amount of the second discharge component 4; similarly, when the second discharge component 4 rotates to discharge, the one-way bearing 52 connected to the first discharge component 3 and the limiting plate 61 arranged near the first discharge component 3 will prevent the first discharge component 3 from rotating with the second discharge component 4.

[0092] Since the volume of the second accommodating groove 41 is smaller than the volume of the first accommodating groove 31, the total amount of coffee beans discharged by the coffee machine will gradually approach the required total amount of coffee beans, thereby achieving the purpose of gradually adjusting the output of coffee beans. When the total amount of coffee beans discharged by the coffee machine reaches the required total amount of coffee beans, the driving member 51 stops rotating, and the discharge process of one coffee preparation is completed.

[0093] Of course, the discharging device of this embodiment can also be applied to other electrical appliances or industrial equipment that need to discharge materials. The discharging device of this embodiment can realize precise automatic processing and improve the working efficiency of the corresponding electrical appliances or industrial equipment.

[0094] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
