Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0051] The utility model provides a bean bin assembly, which is used in appliances such as bean grinders and coffee machines to store food materials such as beans and corn. The bean bin assembly of this embodiment is intended to simplify the locking and unlocking operations of the bean bin body and improve the convenience of installing and removing the bean bin body.

[0052] In the embodiment of the present utility model, Figures 1 to 3 As shown, the bean bin assembly includes a base 1, a bean bin body 2, a locking mechanism 3 and a trigger 4.

[0053] The base 1 is provided with an installation opening 101; the bean bin body 2 is detachably installed on the installation opening 101, and the bean bin body 2 is provided with a limiter 22; the locking mechanism 3 is provided on the base 1, and the locking mechanism 3 has a movable buckle 31, and the buckle 31 can move relative to the base 1 to clamp or disengage from the limiter 22, so that the locking mechanism 3 has a locked state and an unlocked state; the trigger member 4 is movably provided on the base 1 and is transmission-connected with the locking mechanism 3;

[0054] The trigger member 4 can drive the buckle portion 31 to move under the action of external force, so that the lock mechanism 3 switches from the locked state to the unlocked state.

[0055] It can be understood that the base 1 plays the role of mounting the bean bin body 2 to the main body of the appliance, the mounting opening 101 is used to place the bean bin body 2, and the discharge port 201 of the bean bin body 2 can be arranged toward the mounting opening 101, so that the food in the bean bin body 2 can smoothly fall into the main body of the appliance for related processing (such as grinding beans or cooking processing, etc.). The bean bin body 2 is detachably mounted on the mounting opening 101, so that the user can remove the bean bin body 2 from the base 1 to achieve functions such as cleaning, maintenance, or adding food. In this embodiment, by providing a limiter 22 on the bean bin body 2, a locking mechanism 3 and a trigger member 4 are provided on the base 1, and the locking mechanism 3 has a movable buckle 31, and the locking mechanism 3 can move relative to the base 1 through the buckle 31 to clamp or disengage the limiter 22, thereby achieving the function of locking or unlocking the bean bin body 2. When the bean silo body 2 is locked with the base 1, the trigger member 4 can be triggered to drive the buckle portion 31 to move relative to the base 1 to disengage from the limit member 22, so that the locking mechanism 3 is disengaged from the bean silo body 2, thereby realizing the unlocking function of the bean silo body 2.

[0056] It should be noted that the locking state of the locking mechanism 3 can be achieved by triggering the trigger member 4, or it can be achieved without triggering the trigger member 4. As an example, taking the case where locking is achieved by the trigger member 4, when the bean bin body 2 is installed, the trigger member 4 can be triggered to drive the buckle part 31 to move to clamp the limit member 22, thereby locking the bean bin body 2. Or as an example, taking the case where locking is achieved without triggering the trigger member 4, an elastic structure can be provided in the locking mechanism 3 so that the buckle part 31 is in a normally locked state. At this time, it is only necessary to install the bean bin body 2 to the installation port 101, and the buckle part 31 can be clamped with the limit member 22 and is in a locked state. In this way, the trigger member 4 is triggered to drive the buckle part 31 to disengage from the limit member 22 to achieve the unlocking function. The specific transmission connection relationship between the locking mechanism 3 and the trigger member 4 can be determined according to actual conditions and is not limited here.

[0057] In actual application, the specific structure of the position-limiting member 22 can be determined according to the actual situation, such as a convex block structure, a buckle structure or a hook structure, etc. Correspondingly, the specific structure of the buckle connection portion 31 can also be determined according to the actual situation, such as a convex block structure, a buckle structure or a hook structure, etc. As long as it can be ensured that the buckle connection portion 31 can be fixedly held with the position-limiting member 22 when the bean bin body 2 is installed in place. Optionally, the buckle connection portion 31 can be slidably matched or rotationally matched with the base 1.

[0058] In practical application, the trigger member 4 can be rotationally matched or slidably matched with the base 1. The trigger member 4 can be a lever, a button, a knob or a buckle, etc., which is convenient for the user to operate.

[0059] In the bean bin assembly of the utility model, a limiter 22 is provided on the bean bin body 2, and a locking mechanism 3 and a trigger 4 are provided on the base 1. The locking mechanism 3 has a movable buckle 31 to clamp or disengage the limiter 22, thereby realizing the locking or unlocking function of the bean bin body 2. The buckle 31 of the locking mechanism 3 can be directly driven to move by triggering the trigger 4, so that the unlocking function of the bean bin body 2 and the base 1 can be realized. Compared with the solution in the prior art that requires rotating the entire bean bin body 2, this embodiment is more convenient to operate, more convenient, and further improves the user experience.

[0060] In one embodiment of the present application, Figures 3 to 5 The locking mechanism 3 includes a connecting rod 32 and a first elastic member 33. The connecting rod 32 is movably arranged on the base 1 and transmission-connects the trigger member 4 and the buckle portion 31. The first elastic member 33 connects the base 1 and the connecting rod 32 / buckle portion 31 to provide a driving force for the buckle portion 31 to move from an unlocked state to a locked state.

[0061] This embodiment illustrates the structure of the locking mechanism 3. The connecting rod 32 plays the role of transmission connection between the trigger member 4 and the buckle part 31. When the trigger member 4 is triggered, the power can be transmitted to the buckle part 31 through the connecting rod 32 to drive the buckle part 31 to disengage from the limiter 22, so as to realize the function of switching from the locked state to the unlocked state. The first elastic member 33 plays the role of driving the buckle part 31 to move to the locked state. When the bean silo body 2 is installed to the installation port 101, the first elastic member 33 can drive the buckle part 31 to clamp with the limiter 22, and provide the elastic force of the buckle part 31 to clamp the limiter 22, so that the locking reliability of the bean silo body 2 by the locking mechanism 3 is higher. When the bean silo body 2 needs to be removed, after the buckle part 31 is disengaged from the limiter 22 by triggering the trigger member 4, the first elastic member 33 plays the role of resetting the buckle part 31, so that the buckle part 31 is reset to the position of the locked state, so as to facilitate the installation of the bean silo body 2 next time.

[0062] The first elastic member 33 connects the base 1 and the connecting rod 32 / the buckle connection part 31. It can be understood that the first elastic member 33 is connected between the base 1 and the connecting rod 32, and drives the buckle connection part 31 to reset by driving the connecting rod 32 to reset; or the first elastic member 33 connects the base 1 and the buckle connection part 31 to directly drive the buckle connection part 31 to reset. The specific position of the first elastic member 33 can be determined according to actual conditions and is not specifically limited here.

[0063] Optionally, the first elastic member 33 may be a return spring.

[0064] It is understandable that the movable connection relationship between the buckle part 31 and the base 1 can be determined according to actual conditions, for example, it can be a sliding connection or a rotating connection, and the connecting rod 32 can drive the buckle part 31 to slide or rotate relative to the base 1. In this embodiment, considering factors such as the difficulty of structural design and the difficulty of assembly, the buckle part 31 is fixedly connected with the connecting rod 32 and slidably cooperates with the base 1. Such an arrangement can reduce the instability in the motion transmission process and improve the transmission reliability.

[0065] In practical applications, the buckle portion 31 and the connecting rod 32 can be an integral structure or a separate structure.

[0066] In one embodiment of the present application, Figures 3 to 5 The base 1 is provided with a guide groove 102, and the buckle portion 31 is located on the side of the guide groove 102 and can be extended into or retracted from the guide groove 102; when the bean silo body 2 is inserted into the installation opening 101, the limiting member 22 can be driven to slide along the guide groove 102 until it is engaged with the buckle portion 31.

[0067] By providing the guide groove 102 on the base 1, when the bean bin body 2 is installed into the installation opening 101, the limiting member 22 can be driven to slide along the guide groove 102, and the guide groove 102 plays a guiding and limiting role in the installation process of the bean bin body 2. By providing the buckle portion 31 at the side of the guide groove 102, and being able to telescopically move relative to the guide groove 102, and being able to extend into the guide groove 102 or retract out of the guide groove 102, it can be understood that when the buckle portion 31 extends into the guide groove 102, it can be locked with the limiting member 22 to prevent the limiting member 22 from escaping from the guide groove 102; when the buckle portion 31 retracts out of the guide groove 102 and disengages from the limiting member 22, the bean bin body 2 can drive the limiting member 22 to slide out of the guide groove 102.

[0068] As an example, the guide groove 102 may be a groove structure extending axially along the base 1, so that the bean bin body 2 can be inserted into the installation opening 101 along the axial direction, further simplifying the user operation and simplifying the disassembly and assembly of the bean bin body 2. Optionally, the guide groove 102 may be located on the side wall of the installation opening 101 and extend along the axial direction of the installation opening 101.

[0069] Furthermore, if Figures 3 to 5 At least one of the buckling portion 31 and the limiting member 22 is provided with a guiding inclined surface 7.

[0070] By providing a guiding inclined surface 7 on at least one of the buckling portion 31 and the limiting member 22, when the bean silo body 2 is installed, the limiting member 22 can push the buckling portion 31 to move sideways to retract the guide groove 102 to avoid the limiting member 22 when the limiting member 22 moves axially, so that the limiting member 22 can move smoothly to the bottom of the buckling portion 31 (as shown in the direction in the figure), and at the same time, the buckling portion 31 is reset to the position extending into the guide groove 102 under the elastic force of the first elastic member 33, thereby realizing the function of clamping the limiting member 22 and achieving the purpose of locking the bean silo body 2.

[0071] In this embodiment, the guide slope 7 is provided to realize the transmission reversing function between the buckle part 31 and the limiter 22, so that the locking function of the bean bin body 2 can be realized directly by inserting the bean bin body 2 into the installation opening 101 without triggering the triggering member 4. Such a configuration further simplifies the operation of the user.

[0072] It is understandable that the guiding bevel 7 may be provided on the buckle portion 31 alone, or on the limiter 22 alone, or on both the buckle portion 31 and the limiter 22. The specific setting method may be determined according to actual conditions and is not limited here.

[0073] In one embodiment of the present application, Figures 3 to 5 The connecting rod 32 includes two connected connecting arms 321, the trigger member 4 is connected to the connecting portion of the two connecting arms 321, and the free ends of the two connecting arms 321 are each provided with a buckle portion 31, and the two buckle portions 31 are respectively arranged on opposite sides of the installation opening 101; the bean silo body 2 is provided with two limit members 22, and the two limit members 22 correspond to the two buckle portions 31 one by one.

[0074] By configuring the connecting rod 32 to include two connecting arms 321, the free ends of the two connecting arms 321 are connected to the buckling parts 31, so that the two buckling parts 31 are arranged on the opposite sides of the installation opening 101, and correspondingly, two limiting members 22 are respectively provided on the opposite sides of the bean silo body 2. Such a configuration can enable the opposite sides of the bean silo body 2 to be clamped by the buckling parts 31, thereby making the force on the bean silo body 2 more balanced and improving the installation reliability of the bean silo body 2.

[0075] The trigger member 4 is connected to the connection point of the two connecting arms 321. Such a setting can realize the function of only triggering the trigger member 4 to drive the two connecting arms 321 to move at the same time, and then can simultaneously drive the two buckling parts 31 to move, so as to achieve the purpose of synchronous movement of the two. There is no need to set a trigger member 4 separately for each buckling part 31, which further simplifies the structure and improves the compactness of the structure.

[0076] In one embodiment, the base 1 includes a bottom plate 11 and a mounting column 12 disposed on the bottom plate 11. The mounting column 12 is arranged in a ring shape to enclose a mounting opening 101. Two guide grooves 102 are formed on both radial sides of the inner circumferential wall of the mounting column 12. Two connecting arms 321 extend from the connecting end along the outer circumferential wall of the mounting column 12 to correspond to the two guide grooves 102, so that the two buckling portions 31 are respectively arranged on the sides of the two guide grooves 102.

[0077] In one embodiment of the present application, Figures 1 to 5 The trigger member 4 is a lever. With this arrangement, the user can unlock the bean bin body 2 by simply pressing the lever.

[0078] Furthermore, one end of the lever is exposed outside the base 1 , and the other end is in transmission cooperation with the locking mechanism 3 ; the bean bin assembly also includes a second elastic member 41 , which connects the lever and the base 1 .

[0079] In this embodiment, one end of the lever is exposed outside the base 1, increasing the area for user operation and making it easier for the user to press and operate. The other end of the lever extends into the base 1 to cooperate with the locking mechanism 3. Optionally, the lever abuts against the connecting rod 32. When the lever is pressed, the connecting rod 32 can be pushed to drive the buckle 31 out of the guide groove 102, so that the bean bin body 2 is unlocked. The second elastic member 41 connects the lever and the base 1 to reset the lever. When the user releases the lever, the second elastic member 41 can push the lever back to the initial state, and at the same time, the connecting rod 32 and the buckle 31 return to the locked state under the action of the first elastic member 33.

[0080] Optionally, the second elastic member 41 is a return spring.

[0081] In one embodiment of the present application, Figure 2 , Figure 3 , Figures 6 to 8 The bean silo body 2 includes a silo shell 21 and a bean sealing door assembly 23. A discharge port 201 is provided at the bottom of the silo shell 21, and a limiting member 22 is provided on the outside of the silo shell 21; the bean sealing door assembly 23 is provided on the silo shell 21, so as to open the discharge port 201 when the bean silo body 2 is inserted into the installation port 101, and to close the discharge port 201 when the bean silo body 2 leaves the installation port 101.

[0082] This embodiment illustrates the structure of the bean silo body 2, where the silo shell 21 is used to accommodate food, and the discharge port 201 at the bottom of the silo shell 21 is used to discharge food. A bean sealing door assembly 23 is provided in the silo shell 21 to open or close the discharge port 201 when needed. Specifically, when the bean silo body 2 is inserted into the installation port 101, the bean sealing door assembly 23 opens the discharge port 201 so that the food in the silo shell 21 can flow downward. When the bean silo body 2 needs to be disassembled, the locking mechanism 3 is unlocked, and the bean sealing door assembly 23 closes the discharge port 201 to prevent the food in the silo shell 21 from falling to the outside. It can be understood that when the bean silo body 2 is installed in place, the locking mechanism 3 is in a locked state, and at this time, the bean sealing door assembly 23 remains in a position to open the discharge port 201 to smoothly discharge beans.

[0083] Specifically, Figure 3 , Figures 6 to 8 The bean sealing door assembly 23 includes two bean sealing doors 231 and a tension spring 232. The two bean sealing doors 231 are movably arranged at the bottom of the bin shell 21, and the tension spring 232 elastically connects the two bean sealing doors 231; the base 1 is provided with a guide structure 13, and the guide structure 13 has two guide parts 131 opposite to each other, and the two guide parts 131 are respectively used for transmission cooperation with the two bean sealing doors 231; when the bean bin body 2 is inserted into the installation port 101, the two guide parts 131 respectively drive the two bean sealing doors 231 to move backwards to open the discharge port 201, and maintain the discharge port 201 in an open state when the locking mechanism 3 is locked; when the locking mechanism 3 is unlocked, the tension spring 232 drives the two bean sealing doors 231 to move toward each other to close the discharge port 201.

[0084] By connecting the tension spring 232 between the two bean sealing doors 231, the two bean sealing doors 231 are in a state of normally closing the discharge port 201. When the bean bin body 2 is inserted into the installation port 101, the two bean sealing doors 231 will respectively cooperate with the two guide parts 131, and as the bean bin body 2 is inserted and moved, the two guide parts 131 can respectively drive the two bean sealing doors 231 to move backward to open the discharge port 201, until the bean bin body 2 is installed in place and the limiter 22 is locked with the buckle part 31, at which time, the discharge port 201 remains in an open state. When the bean bin body 2 needs to be removed, the trigger member 4 is triggered to unlock the locking mechanism 3, and the clamping force applied to the limit member 22 is eliminated. At this time, the two bean sealing doors 231 will move toward each other under the tension of the tension spring 232 to close the discharge port 201. At the same time, the two guide parts 131 will drive the bin shell 21 to move in a direction away from the installation port 101, so that the bean bin body 2 extends out of the installation port 101 for the user to remove it.

[0085] This embodiment realizes the function that the discharge port 201 automatically opens when the bean bin body 2 is installed on the installation port 101, and automatically closes when the bean bin body 2 is removed from the base 1. The user does not need to perform additional operations on the bean sealing door assembly 23, which further improves the convenience of user operation and improves the user experience.

[0086] As an example, the guide portion 131 is an inclined surface, and the two guide portions 131 of the guide structure 13 are inclined in opposite directions, so that the top of the guide structure 13 forms a vertex structure, and the vertex structure is aligned with the opening and closing seams of the two bean sealing doors 231. Optionally, the guide structure 13 can be in a triangular shape or a cone shape, and the two guide portions 131 can be two adjacent oblique sides.

[0087] When the bean bin body 2 is inserted into the installation opening 101, the top corner structure of the guide structure 13 is inserted into the opening and closing gap of the two bean sealing doors 231. As the bean bin body 2 is inserted, the guide parts 131 on both sides will push the two bean sealing doors 231 to move backwards to open the discharge port 201.

[0088] When the bean bin body 2 needs to be removed, as the bean bin body 2 moves away, the two bean sealing doors 231 move toward each other under the tension of the tension spring 232 until the guide structure 13 is released from between the two bean sealing doors 231 to close the discharge port 201.

[0089] In one embodiment, the bottom plate 11 is provided with a through hole 103 connected to the discharge port 201, and the bottom plate 11 forms a support portion 111 between the hole wall of the through hole 103 and the mounting column 12. When the bean silo body 2 is mounted to the mounting port 101, the support portion 111 abuts against the bottom of the silo shell 21. Optionally, the guide structure 13 is provided at the edge of the support portion 111 at the through hole 103.

[0090] In one embodiment of the present application, Figure 8 The bean bin assembly also includes a micro switch 51 and a safety top rod 52 arranged on the base 1. The micro switch 51 is arranged corresponding to a limit member 22, and the safety top rod 52 is arranged between the micro switch 51 and the limit member 22. When the bean bin body 2 is installed in the installation opening 101, the limit member 22 presses the safety top rod 52 to support the micro switch 51.

[0091] By setting a micro switch 51 on the base 1, the micro switch 51 is connected to the circuit of the whole machine. When the bean bin body 2 is installed in the installation port 101, the micro switch 51 is triggered, so that the circuit of the whole machine is turned on, and then the whole machine will start to perform operations such as grinding beans or cooking. When the bean bin body 2 is not installed, the micro switch 51 is not triggered, and the circuit of the whole machine is not turned on, so it will not start, thereby preventing the phenomenon of mistaken start-up without the bean bin body 2 installed, and further ensuring the user's operation safety.

[0092] By arranging the safety push rod 52 between the micro switch 51 and the limiting member 22 and transmitting the power by installing the push rod 52 , the structural design of the limiting member 22 is simplified.

[0093] In actual application, the limit member 22 corresponding to the micro switch 51 can be protruded downward relative to the bottom of the housing 21 to ensure that the top rod 52 and the micro switch 51 are triggered and installed to prevent poor contact.

[0094] In one embodiment of the present application, Figure 7 The bean bin assembly also includes an infrared sensor 6 disposed on the base 1 for detecting whether the bean bin body 2 is short of beans.

[0095] The infrared sensor 6 is arranged to detect whether beans are lacking, so as to remind the user to add beans in time. Optionally, the infrared sensor 6 is arranged correspondingly below the discharge port 201.

[0096] The utility model further proposes a coffee machine, which includes a bean bin assembly. The specific structure of the bean bin assembly refers to the above-mentioned embodiment. Since the coffee machine adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0097] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
