Description

Technical Field

[0001] This utility model belongs to coffee machine technology, specifically relating to a quick bean changing device for a mother-daughter bean hopper and a coffee machine, which is suitable for scenarios that require frequent switching of coffee bean types (such as multi-user home scenarios). Background Technology

[0002] Most existing coffee machines use a single bean hopper, meaning the bean container only holds one type of coffee bean. Changing beans requires emptying the hopper of any remaining beans, which is cumbersome and wasteful. Some existing dual-bean-hopper designs require stopping the machine, resulting in inefficient switching and negatively impacting the user experience. Residual beans in the hopper can easily mix different types, affecting the flavor of the brewed coffee. Utility Model Content

[0003] This invention addresses the shortcomings of existing coffee machines with dual bean compartment structures and low switching efficiency by providing a quick bean changing device and coffee machine with a mother and daughter bean compartment. It aims to achieve bean changing without stopping the machine, thereby improving bean changing efficiency. It is suitable for scenarios that require frequent switching of coffee bean types (such as multi-user home scenarios).

[0004] To achieve the above objectives, the quick bean changing device for the mother-daughter bean bins of this utility model includes:

[0005] The outer box defines a first inner cavity, which has a first shielding portion and a first discharge port;

[0006] The inner box defines a second inner cavity, which has a second blocking part and a second feeding port. The second blocking part is recessed into the inner box and forms a channel on its outer side. The inner box is rotatably assembled to the first inner cavity to switch between a first position and a second position. A mother bean bin is formed between the outer box and the inner box, and the second inner cavity serves as a daughter bean bin.

[0007] When the inner box is in the first position, the channel corresponds to the first discharge port, the second discharge port is offset from the first discharge port, the mother bean bin is connected to the first discharge port, and the daughter bean bin is blocked from the first discharge port; when the inner box is in the second position, the channel is offset from the first discharge port, the second discharge port corresponds to the first discharge port, the mother bean bin is blocked from the first discharge port, and the daughter bean bin is connected to the first discharge port.

[0008] Therefore, different coffee beans can be stored in the mother bean hopper and daughter bean hopper for different users to choose from. When selecting, simply rotate the inner box between the first and second positions to switch between dispensing from the mother bean hopper or the daughter bean hopper. Switching does not require stopping the machine or emptying the residual coffee beans in the hopper, improving bean changing efficiency and making it convenient to use.

[0009] Preferably, the outer wall of the inner box and the inner wall of the outer box are provided with a first arcuate groove and a first protrusion, respectively. The first arcuate groove has a first notch, and the first protrusion enters or exits the first arcuate groove through the first notch. When the inner box rotates in the first inner cavity, the first protrusion moves within the first arcuate groove. Accordingly, the inner box and the outer box can be disassembled and assembled, increasing the flexibility of use.

[0010] Preferably, when the inner box is in the first and second positions, it is elastically locked by a first locking structure between the inner and outer boxes. This holds the inner box in the corresponding positions. Specifically, the first locking structure includes a first locking portion disposed within a first arcuate groove, and the corresponding first locking portion elastically locks together with a first protrusion when the inner box is in the first and second positions. This first locking structure is compact, concealed, and durable.

[0011] Preferably, the first inner cavity is defined by a bottom wall and a first side wall extending upward from the bottom wall, with the first shielding portion and the first discharge port located on the bottom wall. This facilitates both a larger capacity for the first inner cavity and easy switching between the mother bean bin and the daughter bean bin for discharging from the first discharge port. In particular, the bottom wall is planar, which facilitates its fit with the inner box.

[0012] Preferably, a baffle is rotatably disposed at the bottom of the outer box, located below the first blocking part and the first dispensing port. The baffle has a third blocking part and a third dispensing port. The outer box rotates relative to the baffle, causing it to switch between a locked position and a detached position. When the outer box is in the locked position, the first dispensing port and the third dispensing port are aligned and connected. When the outer box is in the detached position, the first dispensing port and the third dispensing port are misaligned and blocked. Accordingly, the first dispensing port can be closed or opened as needed by the baffle. For example, when the bean changing device is removed from the coffee machine, the first dispensing port is closed by the baffle to prevent coffee beans in the mother bean compartment or daughter bean compartment from leaking out of the first dispensing port. When the bean changing device is installed on the coffee machine, the first dispensing port is opened by the baffle to allow coffee beans in the mother bean compartment or daughter bean compartment to be dispensed from the first dispensing port.

[0013] In particular, when the outer box is in the locked and detached positions, the outer box and the baffle are elastically locked by a second locking structure between the outer box and the baffle. This helps maintain the positional relationship between the baffle and the first discharge port, preventing accidental changes to their positional relationship.

[0014] Preferably, the outer box includes a first cylindrical wall, and the inner box includes a second cylindrical wall. The first cylindrical wall is fitted over the second cylindrical wall, allowing the inner box to rotate smoothly relative to the outer box.

[0015] Preferably, the outer box includes a first inclined wall extending upward from the first cylindrical wall to expand the first inner cavity. This allows for an increase in the capacity of both the mother bean compartment and the daughter bean compartment.

[0016] Preferably, the second shielding portion is a second inclined surface that transitions from the second cylindrical wall to the inner side of the inner box. This facilitates the downward flow of the coffee beans.

[0017] Preferably, the outer box has a positioning reference, and the inner box has a first position mark and a second position mark. When the inner box is in the first position, the first position mark points to the positioning reference; when the inner box is in the second position, the second position mark points to the positioning reference. This facilitates the user in selecting the desired coffee beans.

[0018] To achieve the above objectives, the coffee machine of this utility model includes:

[0019] The top cover has a mounting slot;

[0020] This utility model discloses a quick bean changing device for a mother-daughter bean container. The bean changing device is rotatably installed in the mounting groove so that the outer box can be switched between a locked position and a detached position. The bottom of the outer box is rotatably equipped with a baffle located below the first blocking part and the first feeding port. The baffle has a third blocking part and a third feeding port. The baffle and the mounting groove are separately provided with a first connecting part and a second connecting part. The first connecting part and the second connecting part are combined together to fix the baffle. When the outer box is in the locked position, the first feeding port and the third feeding port are aligned and connected. When the outer box is in the detached position, the first feeding port and the third feeding port are misaligned and blocked.

[0021] Accordingly, when the bean-changing device is installed in the mounting slot of the top plate, the baffle is fixed and cannot rotate. The first feeding port is opened or closed by rotating the outer box. This is particularly suitable for closing the first feeding port when removing the bean-changing device from the mounting slot of the top plate, and opening the first feeding port when installing the bean-changing device into the mounting slot of the top plate. Opening and closing the first feeding port is automatically achieved with the rotation of the outer box, making operation convenient.

[0022] Preferably, when the outer box is in the locked position and the detached position, the outer box and the baffle are elastically locked by a second locking structure between the outer box and the baffle. This helps maintain the positional relationship between the baffle and the first discharge port, preventing accidental changes to their positional relationship.

[0023] Preferably, the mounting slot is a circular slot, and the outer box has a cylindrical portion that is rotatably mounted in the circular slot. This ensures smooth rotation between the outer box and the mounting slot, and a secure installation.

[0024] Preferably, the wall of the circular groove and the surface of the cylindrical part are provided with a third arcuate groove and a third protrusion, respectively. The third arcuate groove has a third notch, and the third protrusion enters or exits the third arcuate groove through the third notch. When the cylindrical part rotates in the circular groove, the third protrusion moves in the third arcuate groove. Accordingly, the bean changing device can be guided to be installed into and removed from the installation groove, so that the bean changing device can be accurately installed in place.

[0025] Preferably, when the outer box is in the locked position, it is elastically locked by a third locking structure located between the outer box and the top cover. This is used to position the bean changing device here and maintain its assembly relationship with the top cover.

[0026] Preferably, the third locking structure includes a third locking part disposed within a third arcuate groove. When the outer box is in the locked position, the third locking part is elastically locked together with the third protrusion. This allows the bean-changing device to be positioned in the locked position, preventing misalignment of the bean-changing device.

[0027] Preferably, one of the first and second joints is an upright column, and the other is a groove or hole. Accordingly, when the bean-changing device is installed in the mounting slot, the column is inserted into the groove or hole to fix the baffle and prevent it from rotating; when the bean-changing device is removed from the mounting slot, the column naturally disengages from the groove or hole. Operation is convenient.

[0028] Preferably, the coffee machine includes a grinding device located under the top cover. The grinding device includes a first grinding wheel and a second grinding wheel. The first grinding wheel is driven by a first motor, and the gap between the second grinding wheel and the first grinding wheel is adjusted by a transmission mechanism. Therefore, the coarseness of the coffee beans can be adjusted as needed.

[0029] Preferably, to intuitively indicate the coarseness of the coffee powder, the coffee machine includes a dial, a potentiometer, and a display screen. Both the dial and the potentiometer are driven by a transmission mechanism. When the dial drives the transmission mechanism to adjust the gap, the transmission mechanism actuates the potentiometer, and the display screen shows the gap setting based on the potentiometer's signal. Alternatively, the coffee machine includes a second motor, a potentiometer, and a display screen. Both the second motor and the potentiometer are driven by a transmission mechanism. The display screen controls the rotation of the second motor to drive the transmission mechanism to adjust the gap. The transmission mechanism actuates the potentiometer, and the display screen shows the gap setting based on the potentiometer's signal.

[0030] This utility model configures an outer box and an inner box. The outer box defines a first inner cavity, which has a first blocking part and a first feeding port. The inner box defines a second inner cavity, which has a second blocking part and a second feeding port. The second blocking part is recessed inward and forms a channel on its outer side. The inner box is rotatably assembled into the first inner cavity to switch between a first position and a second position. A mother bean compartment is formed between the outer box and the inner box, and the second inner cavity serves as a daughter bean compartment. When the inner box is in the first position, the channel corresponds to the first feeding port, the second feeding port is offset from the first feeding port, the mother bean compartment is connected to the first feeding port, and the daughter bean compartment is blocked from the first feeding port. When the inner box is in the second position, the channel is offset from the first feeding port, the second feeding port corresponds to the first feeding port, the mother bean compartment is blocked from the first feeding port, and the daughter bean compartment is connected to the first feeding port. Therefore, different coffee beans can be stored in the mother bean hopper and daughter bean hopper for different users to choose from. When selecting, simply rotate the inner box between the first and second positions to switch between dispensing from the mother bean hopper or the daughter bean hopper. Switching does not require stopping the machine or emptying the residual coffee beans in the hopper, improving bean changing efficiency and making it convenient to use. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0055] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0056] In the description of this utility model, it should be understood that the technical features defined by terms such as "first," "second," and "third," which have a sequential concept, are only used to clearly describe the defined technical features and to clearly distinguish the defined technical features from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0057] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0058] like Figure 1-5 , Figure 6-11 As shown, the quick bean changing device 1000 is presented as a bean box that can be installed as a whole onto the top plate 2000 and removed from the top plate. The bean changing device includes an outer box 100, an inner box 200, and a baffle 400.

[0059] The outer box 100 defines a first inner cavity 101, which has a first shielding portion 102 and a first discharge port 103.

[0060] The inner box 200 defines a second inner cavity 201, which has a second blocking portion 202 and a second discharge port 203. The second blocking portion 202 is recessed inward and forms a channel 204 on its outer side. The inner box 200 is rotatably mounted to the first inner cavity 101. Figure 8-9 The first position shown is Figure 10-11 Interchange the positions shown in the second position, and in Figure 6 , Figure 7 Solid lines indicate the inner box is in the first position, and dashed lines indicate the inner box is in the second position. For example... Figure 9 , Figure 11As shown, a mother bean storage 300 is formed between the outer box 100 and the inner box 200, and the second inner cavity 201 serves as a daughter bean storage.

[0061] In the illustrated structure, the inner box 200 and the outer box 100 are elastically locked by a first locking structure. Specifically, the outer wall of the inner box 200 and the inner wall of the outer box 100 are respectively provided with a first arc groove 209 and a first protrusion. The first arc groove 209 has a first notch 210. The first protrusion enters or exits the first arc groove 209 through the first notch 210. When the inner box 200 rotates in the first inner cavity 101, the first protrusion moves within the first arc groove 209, constraining the inner box to the outer box (unless the inner box rotates to the position corresponding to the first protrusion and the first notch 210). Accordingly, the inner box and the outer box can be disassembled and assembled, increasing the flexibility of use.

[0062] Furthermore, when the inner box is in the first and second positions, it is elastically locked by the first locking structure between the inner and outer boxes. This holds the inner box in the corresponding position. Specifically, the first locking structure includes a first locking portion 211 disposed within a first arcuate groove 209. When the inner box is in the first and second positions, the first locking portion 211 is elastically locked together with a first protrusion. Specifically, the first locking portion and the first protrusion are respectively shaped as a groove and a rib, with the rib sinking into the groove to achieve locking. When the inner box is rotated, the elastic deformation of the rib and / or the groove causes the rib to sink into or dislodge from the groove, achieving elastic locking. This holds the inner box in the corresponding position. The first protrusion is identical to the third protrusion structure described below.

[0063] In other embodiments, the inner box and the outer box can be assembled together using a shaft to achieve rotation.

[0064] When the inner box 200 is in the first position, the channel 204 corresponds to the first discharge port 103, the second discharge port 203 is offset from the first discharge port 103, the mother bean bin 300 is connected to the first discharge port 103, and the daughter bean bin is blocked from the first discharge port 103. When the inner box 200 is in the second position, the channel 204 is offset from the first discharge port 103, the second discharge port 203 corresponds to the first discharge port 103, the mother bean bin 300 is blocked from the first discharge port 103, and the daughter bean bin is connected to the first discharge port 103.

[0065] Therefore, different types of coffee beans can be stored in the mother bean hopper and daughter bean hopper for different users to choose from. When selecting, users only need to rotate the inner box between the first and second positions to switch between dispensing from the mother bean hopper or the daughter bean hopper. Switching does not require stopping the machine or emptying the residual coffee beans in the hopper, improving bean changing efficiency and making it convenient to use.

[0066] In the illustrated structure, the first inner cavity 101 is defined by a bottom wall 104 and a first side wall 105 extending upward from the bottom wall. The first shielding portion 102 and the first dispensing port 103 are located on the bottom wall 104. This facilitates a larger capacity for the first inner cavity and allows for easy switching between the mother bean hopper and the daughter bean hopper, with coffee beans being dispensed from the first dispensing port. In particular, the bottom wall 104 is planar, which facilitates its fit with the second dispensing port of the inner container, reducing the likelihood of coffee beans getting stuck.

[0067] In the illustrated structure, a baffle 400 is rotatably disposed at the bottom of the outer box 100, located below the first blocking part 102 and the first dispensing port 103. The baffle 400 has a third blocking part 401 and a third dispensing port 402. The outer box 100 rotates relative to the baffle 400, causing the outer box to switch between a locked position and a detached position. When the outer box is in the locked position, the first dispensing port 103 and the third dispensing port 402 are aligned and connected. When the outer box is in the detached position, the first dispensing port 103 and the third dispensing port 402 are misaligned and blocked. Accordingly, the first dispensing port can be closed or opened as needed by the baffle. For example, when the bean changing device is removed from the coffee machine, the first dispensing port is closed by the baffle to prevent coffee beans in the mother bean compartment or daughter bean compartment from leaking out of the first dispensing port. When the bean changing device is installed on the coffee machine, the first dispensing port is opened by the baffle to allow coffee beans in the mother bean compartment or daughter bean compartment to be dispensed from the first dispensing port.

[0068] In the illustrated structure, the outer box 100 is located at Figure 4-5 The lock position and Figure 1-3 When in the detached position, it is elastically locked by the second locking structure located between the outer box 100 and the baffle 400. For example... Figure 7 As shown, the second locking structure includes two second protrusions 106 on the outer box and a second slot 403 on the edge of the baffle. The outer box is located in Figure 4-5 The lock position and Figure 1-3 In each of the shown detachment positions, a second protrusion is located within the second slot to achieve elastic locking. The elastic locking occurs when the outer box rotates, and the second protrusion, or / and the second slot, elastically deforms to engage with the second slot. Similarly, the second protrusion can also disengage from the second slot through elastic deformation. This helps maintain the positional relationship between the baffle and the first discharge port, preventing accidental changes to their positional relationship.

[0069] In the illustrated structure, the outer box 100 includes a first cylindrical wall 107, and the inner box 200 includes a second cylindrical wall 205. The first cylindrical wall 107 is fitted over the second cylindrical wall 205, allowing the inner box to rotate smoothly relative to the outer box.

[0070] In the illustrated structure, the outer box 100 includes a first inclined wall 108 extending upward from the first cylindrical wall 107 to expand the first inner cavity. This allows for the expansion of both the mother bean compartment and the daughter bean compartment.

[0071] In the illustrated structure, the second shielding portion 202 is a second inclined surface that transitions from the second cylindrical wall 206 to the inner side of the inner box. This facilitates the downward flow of the coffee beans.

[0072] In the illustrated structure, the outer box 100 is provided with a positioning reference 110, and the inner box 200 is provided with a first position mark 207 and a second position mark 208. The inner box 200 is as follows... Figure 8-9 As shown, when in the first position, the first position mark 207 points to the positioning reference 110, and the inner box is as follows. Figure 10-11 When in the second position, the second position mark 208 points to the positioning reference 110. This allows the user to easily select the desired coffee beans. Figure 9 The arrows in the diagram indicate the path of the coffee beans falling from the mother bean hopper to the first feed inlet 103. Figure 11 The arrows indicate the path of the coffee beans falling from the bean hopper to the first feed inlet 103. Specifically, the outer box 100 is equipped with a first lid 115, and the inner box 200 is equipped with a second lid 212. A positioning reference 110 is located at the upper edge of the first side wall 105, and a first position mark 207 and a second position mark 208 are located on the surface of the second lid 212. Therefore, when the first lid 115 is opened, the positioning reference 110, the first position mark 207, and the second position mark 208 are visible, allowing the inner box to be rotated as needed.

[0073] In addition, a guide surface 213 is provided in the inner box 200. The guide surface is umbrella-shaped and is used to guide the coffee beans in the inner box to be fed.

[0074] like Figure 12-13 The diagram shows a portion of the coffee machine's structure. The coffee machine includes a top cover 2000, a quick bean changing device 1000 (mother and daughter bean hoppers), and a bean grinder 3000.

[0075] The top cover 2000 has a mounting slot 2001, and the top cover is usually located on the top of the coffee machine body.

[0076] The quick bean-changing device 1000 for the mother and daughter bean hoppers is rotatably mounted in the mounting groove 2001, allowing the outer box to be switched between a locked position and a detached position. A baffle 400 is rotatably mounted on the bottom of the outer box 100, located below the first blocking part 102 and the first feeding port 103. The baffle 400 has a third blocking part 401 and a third feeding port 402. A first connecting part 2002 and a second connecting part 404 are separately provided within the mounting groove 2001, and the first and second connecting parts are joined together to fix the baffle. When the outer box is in the locked position, the first feeding port 103 and the third feeding port 402 are aligned and connected; when the outer box is in the detached position, the first feeding port 103 and the third feeding port 402 are misaligned and blocked. The baffle 400 is rotatably mounted to the bottom of the outer box by its central axis, ensuring that the baffle and the outer box can only rotate and cannot be separated.

[0077] Accordingly, when the bean changing device 1000 is installed into the mounting slot 2001 of the top plate 2000, the baffle 400 is fixed and cannot rotate. The first feeding port 103 is opened or closed by rotating the outer box 100. This is suitable for closing the first feeding port 103 when the bean changing device 1000 is removed from the mounting slot 2001 of the top plate 2000, and opening the first feeding port 103 when the bean changing device 1000 is installed into the mounting slot of the top plate. The opening and closing of the first feeding port are automatically achieved with the rotation of the outer box, making operation convenient.

[0078] In the illustrated structure, the mounting slot 2001 is a circular slot, and the outer box has a cylindrical portion 111, which is rotatably mounted in the circular slot. This allows the outer box and the mounting slot to rotate smoothly and be securely installed.

[0079] In the illustrated structure, the wall of the circular groove and the surface of the cylindrical part are separately provided with a third arc groove 113 and a third protrusion 2003. The third arc groove has a third notch 112. The third protrusion 2003 enters or exits the third arc groove through the third notch 112. When the cylindrical part 111 rotates in the circular groove, the third protrusion 2003 moves in the third arc groove 113, constraining the bean changing device to the top cover (unless the bean changing device rotates to the point where the third protrusion corresponds to the third notch 112). Accordingly, the bean changing device can be guided to be installed into and removed from the mounting slot, allowing the bean changing device to be accurately installed in place.

[0080] In the illustrated structure, when the outer box 100 is in the locked position, it is elastically locked by a third locking structure located between the outer box 100 and the top cover 2000. This positions the bean changing device in this position, maintaining its assembly relationship with the top cover. Specifically, the third locking structure includes a third locking part 112 located within a third arcuate groove 113. When the outer box 100 is in the locked position, the third locking part 112 is elastically locked together with the third protrusion 2003. This allows the bean changing device to be positioned in the locked position, preventing it from rotating out of place.

[0081] In the illustrated structure, one of the first joint 2002 and the second joint 404 is an upright column, and the other is a groove or hole. Accordingly, when the bean-changing device is installed in the mounting slot, the column is inserted into the groove or hole to fix the baffle and prevent it from rotating. When the bean-changing device is removed from the mounting slot, the column naturally disengages from the groove or hole. Operation is convenient.

[0082] As mentioned above, different types of coffee beans are stored in the mother bean hopper 300 and the daughter bean hopper, respectively. Figure 1-2 As shown, when the first feed port 103 is closed by the baffle 400, the bean changing device 1000 is placed downwards in the mounting groove 2001 of the top cover 2000, with the third protrusion 2003 corresponding to the third notch 112 and the first joint 2002 corresponding to the second joint 404. Then, as shown... Figure 3Rotate the outer box in the direction indicated by the middle arrow until it reaches the desired position.
