Description

Technical Field

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

[0002] With the improvement of social productivity, instant coffee, which is not as rich and complex in taste and flavor as freshly ground coffee, has gradually failed to keep up with people's pursuit of quality of life. Freshly ground coffee retains the natural flavor and aroma of coffee beans, providing more choices of taste and flavor. Different brewing methods and personal taste preferences require different coffee powder grinding degrees to achieve the best brewing effect. Different flavors of coffee, such as mocha, Italian, American, French, etc., have higher requirements for the accuracy of coffee powder.

[0003] However, there are still many shortcomings in the grinding equipment on the market, especially in terms of controlling the amount of coffee powder output. Before using a coffee machine, coffee beans of appropriate weight are generally selected and put into the bean grinding device for grinding. The specific weight information of the coffee beans is generally obtained by rough estimation based on user experience. If the number of coffee beans is too large, the coffee will be too strong; if the number is small, it will affect the subsequent coffee production and the taste of the coffee. For new users, the experience is poor. Some users will choose an external weighing device to weigh the coffee beans, but this method makes the entire operation process more cumbersome and requires the addition of weighing equipment, which is inconvenient to use. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a coffee bean output device, which, by arranging a weighing mechanism and a control mechanism, weighs the coffee beans in the bean storage mechanism or the bean storage mechanism, and controls the opening and closing of the bean output port through the control mechanism, thereby improving the precise control of the coffee bean output amount, thereby achieving precise control of the amount of coffee powder obtained in subsequent operations and ensuring the taste of the final coffee; the present invention also provides a coffee powder output device and a coffee machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A coffee bean discharging device, comprising:

[0007] A bean storage mechanism, comprising a bean storage container and a valve assembly, wherein the bean storage container has a bean storage chamber for storing coffee beans, and is provided with a bean outlet communicated with the bean outlet chamber for conveying coffee beans outward; the valve assembly comprises a valve structure and a valve driving structure, wherein the valve structure is movably arranged at the bean outlet and can move between a closed position for completely closing the bean outlet and an open position for completely opening the bean outlet; the valve driving structure is drivingly connected to the valve structure to drive the valve structure to move between the closed position and the open position;

[0008] A weighing mechanism, which is used to weigh the bean storage mechanism or the coffee beans in the bean storage mechanism;

[0009] and a control mechanism connected to the weighing mechanism to determine the weight of coffee beans that the bean storage mechanism needs to output during the bean output process, and to control the working state of the valve drive structure according to the weight of the coffee beans that need to be output.

[0010] With the above structure, after the control mechanism receives the total amount of coffee beans that need to be output, the valve driving structure is controlled to move to drive the valve structure from the closed position to the open position, thereby opening the bean outlet, and the coffee beans are output through the bean outlet; during the falling process, the weighing mechanism detects the weight of the bean storage mechanism or the coffee beans in the bean storage mechanism in real time and sends a signal to the control mechanism, and the control mechanism obtains the weight of the coffee beans that have been output according to the weight detected by the weighing mechanism before the coffee beans are output and the current detected weight, and then obtains the weight of the coffee beans that need to be output in combination with the total weight of the coffee beans that need to be output. When the weight of the coffee beans that need to be output is 0 or is close to 0, the control mechanism controls the valve driving structure to move in the opposite direction to drive the valve structure from the open position to the closed position, thereby closing the bean outlet; the above structure can improve the precise control of the output amount of coffee beans, thereby realizing the precise control of the amount of coffee powder obtained in the subsequent operation, and ensuring the taste of the final coffee; specifically, the valve structure adopts a sheet structure;

[0011] Of course, the control mechanism can determine whether the existing weight of coffee beans is greater than or equal to the total weight of coffee beans to be output before discharging the beans, and can remind the customer if it does not meet the requirement; specifically, the weighing mechanism detects the overall weight of the bean storage mechanism, and the control mechanism can obtain the weight of the coffee beans in the bean storage mechanism by subtracting the weight of the built-in bean storage mechanism from the weight detected by the weighing mechanism;

[0012] It should be noted that completely closing the bean outlet should not be simply understood as the valve structure completely closing the bean outlet, but should be understood as: when the valve structure is in the closed position, coffee beans cannot pass through the bean outlet, which can be understood as completely closing the bean outlet;

[0013] The control mechanism can be a programmable control chip such as a single-chip microcomputer, or it can be built through a logic circuit or an operation circuit;

[0014] The total amount of coffee beans that need to be outputted can be determined by setting an input module to allow the customer to input a specific value, or by allowing the customer to input the type of coffee, and the device automatically determines the corresponding total amount of coffee beans that need to be outputted.

[0015] Further, the valve drive structure includes a motor and an intermediate drive unit for converting the rotational motion of the motor output shaft into the motion of the valve structure, and the output shaft of the motor is drivingly connected to the valve structure through the intermediate drive unit to drive the valve structure to move;

[0026] Specifically, along the clockwise or counterclockwise direction, the groove portion is inclined toward the axis side of the bean outlet, so that the guide wheel drives the valve structure to rotate to control the opening size of the bean outlet.

[0027] Furthermore, the guide wheel is rotatably arranged around the axis of the bean outlet.

[0028] The above structure makes the arrangement of the guide wheel more reasonable, making it easier for it to drive the valve structure.

[0031] Furthermore, a plurality of valve structures are provided, and the plurality of valve structures are close to each other to close the bean outlet or are away from each other to open the bean outlet.

[0032] By adopting the above structure, the arrangement of the coffee bean discharging device is more reasonable, and the multiple valve structures can make the opening and closing of the bean discharging port faster, further reducing the bean discharging error rate.

[0033] The valve driving structure synchronously drives the multiple valve structures to move.

[0034] Furthermore, the bean storage mechanism includes a valve mounting shell for mounting and accommodating the valve assembly, the bean storage container is mounted on the valve mounting shell, and the bean outlet on the bean storage container faces the valve mounting shell, and the valve mounting shell is provided with a bean outlet channel running through it at a position opposite to the bean outlet; the valve structure is movably arranged at the bean outlet channel, and a valve inlet and outlet hole for the valve structure to enter and exit the bean outlet channel is opened on the side wall of the bean outlet channel.

[0035] With the above structure, the arrangement of the valve installation housing provides an environmental basis for the installation of the valve assembly, and the valve installation housing can play a certain protective role on the valve assembly;

[0036] The arrangement of the bean discharging channel and the inlet and outlet holes makes the arrangement of the valve mounting housing more reasonable, thus avoiding affecting the movement of the valve structure and the bean discharging.

[0037] Further, a valve mounting portion for rotatably mounting the valve structure is provided in the valve mounting housing; a first abutting portion and a second abutting portion are provided in the valve mounting housing, and the first abutting portion abuts against a side of the valve structure away from the bean outlet when the valve structure is located in the open position, and the second abutting portion abuts against a side of the movable end of the valve structure facing the bean outlet when the valve structure is located in the closed position; a abutting connecting portion is provided in the valve mounting housing between the first abutting portion and the second abutting portion, and the abutting connecting portion matches the motion trajectory of the movable end of the valve structure.

[0038] The above structure makes the arrangement of the valve mounting housing more reasonable; the valve mounting portion can rotatably mount the valve structure; and the arrangement of the first abutting portion and the second abutting portion can limit the range of motion of the valve structure.

[0039] Furthermore, the weighing mechanism comprises a pressure sensor, and the pressure sensor is arranged below the bean storage mechanism to receive the pressure applied by the bean storage mechanism to it and output a corresponding signal.

[0040] With the above structure, the pressure sensor detects the pressure applied by the bean-discharging mechanism and outputs a corresponding signal to the control mechanism. The control mechanism infers the current total weight of the bean-discharging mechanism according to the pressure.

[0041] Furthermore, the weighing mechanism also includes an upper weighing shell and a lower weighing shell, the upper weighing shell is located above the lower weighing shell, and the upper weighing shell can move in a vertical direction relative to the lower weighing shell, the pressure sensor is arranged between the upper weighing shell and the lower weighing shell, and the bean storage mechanism is located above the upper weighing shell.

[0042] By adopting the above structure, the structure of the weighing mechanism is more reasonable, and the upper weighing shell and the lower weighing shell protect the pressure sensor without affecting the detection of the bean storage mechanism by the pressure sensor.

[0043] Further, the bean outlet is arranged on the bottom surface of the bean storage chamber, and along the radial outward direction of the bean outlet, the bottom surface is gradually inclined toward the top surface side of the bean storage chamber.

[0044] By adopting the above structure, the structural arrangement of the bean storage chamber is more reasonable, so that the coffee can fall from the bean outlet under the influence of gravity.

[0045] Furthermore, the bean storage container is provided with a bean inlet which is communicated with the bean storage cavity and is used for coffee beans to enter the bean storage cavity.

[0046] By adopting the above structure, the structural arrangement of the bean storage chamber is more reasonable, which makes it convenient for the user to put coffee beans into the bean outlet chamber.

[0047] Further, the bean storage mechanism includes a cavity cover that matches the bean inlet and is used to cover the bean inlet, and the cavity cover is detachably installed at the bean inlet.

[0048] With the above structure, the cavity cover can effectively prevent the coffee beans from contacting with the outside air, thus ensuring the storage environment of the coffee beans.

[0085] And a control mechanism 3, which is connected to the weighing mechanism 2 to determine the weight of coffee beans that the bean storage mechanism 1 needs to output during the bean output process, and controls the working state of the valve driving structure 1022 according to the weight of coffee beans that need to be output.

[0086] With the above structure, when the control mechanism 3 receives the total amount of coffee beans that need to be output, it controls the valve driving structure 1022 to drive the valve structure 1021 to move from the closed position to the open position, so as to open the bean outlet 1012, and the coffee beans are output through the bean outlet 1012; during the falling process, the weighing mechanism 2 detects the weight of the bean storage mechanism 1 or the coffee beans in the bean storage mechanism 1 in real time and sends a signal to the control mechanism 3, and the control mechanism 3 obtains the output according to the weight detected by the weighing mechanism 2 before the coffee beans are output and the current detected weight. The weight of the coffee beans output is combined with the total weight of the coffee beans to be output to obtain the weight of the coffee beans that need to be output. When the weight of the coffee beans that need to be output is 0 or is close to 0, the control mechanism 3 controls the valve drive structure 1022 to move in the reverse direction to drive the valve structure 1021 from the open position to the closed position to close the bean outlet 1012. The above structure can improve the precise control of the output amount of coffee beans, thereby achieving precise control of the amount of coffee powder obtained in subsequent operations and ensuring the taste of the final coffee. Specifically, the valve structure 1021 adopts a sheet structure.

[0087] Of course, the control mechanism 3 can determine whether the existing weight of coffee beans is greater than or equal to the total weight of coffee beans to be output before the beans are output, and can remind the customer if it is not satisfied; specifically, the weighing mechanism 2 detects the overall weight of the bean storage mechanism 1, and the control mechanism 3 subtracts the weight of the built-in bean storage mechanism 1 from the weight detected by the weighing mechanism 2 to obtain the weight of the coffee beans in the bean storage mechanism 1;

[0088] It should be noted that completely closing the bean outlet 1012 should not be simply understood as the valve structure 1021 completely closing the bean outlet 1012, but should be understood as: when the valve structure 1021 is in the closed position, coffee beans cannot pass through the bean outlet 1012, which can be understood as completely closing the bean outlet 1012;

[0089] The control mechanism 3 can be a programmable control chip such as a single chip microcomputer, or can be constructed by a logic circuit or an operation circuit;

[0090] The total amount of coffee beans that need to be outputted can be determined by setting an input module to allow the customer to input a specific value, or by allowing the customer to input the type of coffee, and the device automatically determines the corresponding total amount of coffee beans that need to be outputted.

[0091] Further, the valve driving structure 1022 includes a motor 1022a and an intermediate driving unit 1022b for converting the rotational motion of the output shaft of the motor 1022a into the motion of the valve structure 1021. The output shaft of the motor 1022a is drivingly connected to the valve structure 1021 through the intermediate driving unit 1022b to drive the valve structure 1021 to move.

[0092] The control mechanism 3 is connected to the motor 1022a to control the rotation direction and rotation angle of the output shaft of the motor 1022a.

[0093] By adopting the above structure, the structure of the valve driving structure 1022 is more reasonable, which is convenient for the control mechanism 3 to control the valve driving mechanism; specifically, the movement of the valve structure 1021 is associated with the rotation direction and rotation angle of the output shaft of the motor 1022a, and the control mechanism 3 only needs to control the rotation direction of the output shaft of the motor 1022a to control the movement direction of the valve structure 1021, and control the rotation angle of the motor 1022a to control the position reached by the movement of the valve structure 1021.

[0094] Furthermore, the valve structure 1021 is rotatably disposed at the bean outlet 1012 .

[0095] By adopting the above structure, the arrangement of the valve structure 1021 is more reasonable, so as to facilitate the control of the opening and closing of the bean outlet 1012; of course, in other embodiments, the valve structure 1021 can be arranged at the bean outlet 1012 in a sliding manner.

[0096] Furthermore, the rotation axis of the valve structure 1021 is formed at one end of the valve structure 1021 , and the rotation axis of the valve structure 1021 is perpendicular to the surface where the bean outlet 1012 is located.

[0097] By adopting the above structure, the arrangement of the valve structure 1021 is more reasonable, so that it can control the opening and closing of the bean outlet 1012; the above structure enables the valve structure 1021 to rotate parallel to the bean outlet 1012, which can avoid the valve structure 1021 from affecting the falling of the coffee beans, making the falling of the coffee beans smoother and reducing the possibility of coffee beans being blocked.

[0098] Furthermore, the rotation axis of the valve structure 1021 is located radially outside the bean outlet 1012 .

[0099] The above structure makes the arrangement of the valve structure 1021 more reasonable. The above structure can prevent the installation of the valve structure 1021 from affecting the falling of the coffee beans, making the falling of the coffee beans smoother and reducing the possibility of coffee beans being blocked.
