Description

Technical Field

[0001] This utility model belongs to the field of coffee machine technology, and specifically provides a coffee machine and its bean hopper. Background Technology

[0002] Coffee machines are commonly used beverage preparation devices in daily life. The coffee bean hopper, which stores coffee beans, has a significant impact on the taste and quality of coffee.

[0003] When using the coffee hopper, users typically add the appropriate amount of coffee beans based on experience. This can easily lead to two problems: adding too few beans results in a low concentration of coffee, affecting the taste, especially when making multiple cups; while adding too many beans leads to leftover beans and waste. Utility Model Content

[0004] One objective of this invention is to solve the problem that existing coffee machines cannot allow users to put the appropriate amount of coffee beans into the bean hopper, which easily leads to too many or too few coffee beans in the hopper.

[0005] To achieve the above objectives, the present invention provides a coffee bean hopper for a coffee machine in a first aspect, comprising:

[0006] Warehouse body;

[0007] A support member is disposed at the bottom of the chamber and integrally formed with the chamber or fixedly connected in the circumferential direction. The support member is used to carry coffee beans and has at least one discharge port.

[0008] A base is rotatably connected to the bottom of the chamber body, so that the base can open or cover the discharge port by rotating relative to the chamber body;

[0009] A weighing module is installed on the base and used to weigh the load-bearing component.

[0010] Optionally, the bottom of the hopper is provided with a tapering structure, and the outer side of the tapering structure is provided with a protrusion; the base includes a collar sleeved on the outer side of the tapering structure, the top of the collar is provided with a clearance notch for avoiding the protrusion, and the collar is provided with slots at both ends of the clearance notch in the circumferential direction that are adapted to the protrusion, so that one of the two slots is inserted into the protrusion when the base opens the discharge port, and the other of the two slots is inserted into the protrusion when the base covers the discharge port.

[0011] Optionally, the base further includes a baffle plate with at least one discharge hole. The discharge hole can be rotated relative to the supporting member to a position aligned with the discharge port to open the discharge port. The discharge hole can also be rotated relative to the supporting member to a position misaligned with the discharge port to cover the discharge port.

[0012] Optionally, there are two discharge ports and two discharge holes, which are centrally symmetrical with respect to the rotation axis of the hopper and the base, respectively; and / or, the baffle has a receiving groove at its center with an opening facing the bearing member to receive the weighing module, the weighing module abutting against the bearing member; and / or, the base further includes an inner ring located inside the collar, the baffle being disposed at the top of the inner ring so that the baffle is located within the constriction structure and slides in contact with or gap-fits the bearing member.

[0013] Optionally, the bean hopper also includes a locking pin and a spring, the locking pin and the spring being used to lock the base and the hopper body to the position where the discharge port is covered.

[0014] Optionally, the constriction structure is provided with a receiving cavity with an opening facing the base, the locking pin and the spring are both arranged in the receiving cavity, and the locking pin is located on the side of the spring closer to the base; the base is provided with a locking groove; when the base and the hopper are in a position where the discharge port is blocked, the locking pin is inserted into the locking groove.

[0015] Optionally, the outer side of the collar is provided with a snap-fit ​​structure so that the bean hopper can be snapped onto the body of the coffee machine through the snap-fit ​​structure.

[0016] Optionally, the interior of the silo body is provided with anti-rotation ribs, and the bearing member is provided with anti-rotation grooves. The anti-rotation ribs are embedded in the anti-rotation grooves so that the bearing member and the silo body are relatively fixed in the circumferential direction.

[0017] Optionally, the height of the inner bottom surface of the supporting member gradually decreases towards the discharge port.

[0018] Optionally, a fixing column is provided in the middle of the supporting member, and the bean bin also includes an umbrella-shaped member disposed in the bin body, the umbrella-shaped member being inserted into the fixing column.

[0019] Optionally, the weighing module includes a connection terminal, which is provided with a magnetic component so that the connection terminal is electrically connected to the body of the coffee machine by magnetic attraction.

[0020] In a second aspect, this invention provides a coffee machine comprising the bean hopper described in any one of the first aspects.

[0021] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by setting a supporting component inside the hopper to support coffee beans, and by setting a base rotatably connected to the bottom of the hopper to open or cover the outlet on the supporting component, the storage and release of coffee beans in the bean hopper is achieved. By setting a weighing module on the base for weighing the supporting component, the coffee machine of this utility model with the above-mentioned bean hopper structure can detect the weight of the coffee beans on the supporting component, thereby allowing the user to add an appropriate amount of coffee beans into the bean hopper, avoiding adding too many or too few coffee beans.

[0022] Furthermore, by configuring a closing structure for the hopper body and a collar for the base, the base and hopper body can be connected together via the collar and closing structure. By providing a protrusion on the outer side of the closing structure, an clearance notch at the top of the collar, and slots at both ends of the clearance notch that match the protrusion, the protrusion on the closing structure can be embedded into the clearance notch and engaged with the slots when the hopper body and base rotate relative to each other, thus achieving axial fixation between the hopper body and base.

[0023] Furthermore, the discharge port is opened by configuring a baffle with at least one discharge hole on the base and enabling the discharge hole to rotate relative to the supporting member to a position aligned with the discharge port on the supporting member; and the discharge port is blocked by enabling the discharge hole to rotate relative to the supporting member to a position misaligned with the discharge port on the supporting member.

[0024] Furthermore, by providing a receiving groove with an opening at the center of the baffle facing the supporting member to accommodate the weighing module and to make the weighing module abut against the supporting member, the weighing module can make the weighing results of the supporting member and the coffee beans on it more accurate.

[0025] Furthermore, by using locking pins and springs to lock the base and the chamber in a position where the outlet is covered, it is prevented that the base and the chamber will rotate accidentally and open the outlet, which would cause the coffee beans in the bean hopper to be weighed inaccurately or fall to the ground.

[0026] Furthermore, by setting a snap-fit ​​structure on the outside of the collar, the bean hopper can be snapped onto the body of the coffee machine, making it convenient for users to install and remove the bean hopper.

[0027] Furthermore, by setting anti-rotation ribs inside the silo body and anti-rotation grooves on the load-bearing components, and embedding the anti-rotation ribs into the anti-rotation grooves, the load-bearing components and the silo body are relatively fixed in the circumferential direction, thereby preventing relative rotation between the load-bearing components and the silo body when the silo body and the base rotate relative to each other.

[0028] Furthermore, by gradually lowering the height of the inner bottom surface of the supporting component towards the outlet, the coffee beans inside the supporting component can be completely discharged from the outlet under their own weight.

[0029] Furthermore, by setting a magnetic component on the connection terminal of the weighing module, the connection terminal can be electrically connected to the coffee machine body by magnetic attraction, which facilitates the installation and removal of the bean hopper by the user.

[0057] like Figure 1 As shown, in this utility model, the coffee machine 001 includes a bean hopper 100 and a body 200 for mounting the bean hopper 100. The bean hopper 100 is used to store coffee beans. See below for further details. Figures 2 to 10 Let's take a detailed look at the Bean Warehouse 100.

[0058] like Figures 2 to 4 As shown, in some embodiments of this utility model, the bean hopper 100 includes a hopper body 110, a load-bearing component 120, a base 130, and a weighing module 140.

[0059] The compartment 110 is used to store coffee beans.

[0060] The supporting member 120 is disposed at the bottom of the chamber 110 and is integrally formed with the chamber 110 or fixedly connected in the circumferential direction. The supporting member 120 is used to carry coffee beans. The supporting member 120 is provided with at least one discharge port 1201 so that the coffee beans in the chamber 110 can be discharged through the discharge port 1201.

[0061] The base 130 is rotatably connected to the bottom of the hopper 110, so that the base 130 can open or cover the discharge port 1201 by rotating relative to the hopper 110.

[0062] The weighing module 140 is mounted on the base 130 and is used to weigh the load-bearing component 120.

[0063] In this invention, the weighing module 140 can be any feasible sensor, such as a resistance strain gauge load cell, a capacitive load cell, a pressure load cell, a single-point load cell, a shear beam sensor, or a column sensor.

[0064] Those skilled in the art will understand that the coffee machine 001 of the present invention, which has the above-described bean hopper 100 structure, can detect the weight of the coffee beans on the supporting component 120, thereby enabling the user to add an appropriate amount of coffee beans into the bean hopper 100 accordingly, avoiding adding too many or too few coffee beans into the bean hopper 100.

[0065] Furthermore, although not shown in the figure, in some embodiments of this utility model, those skilled in the art may, as needed, install a display screen on the body 200 of the coffee machine 001 to display the weight of the coffee beans, so that the user can observe the weight of the coffee beans in the chamber 110 in real time.

[0066] like Figures 2 to 4 As shown, in some embodiments of this utility model, the bottom of the compartment 110 is provided with a tapering structure 111, and the outer side of the tapering structure 111 is provided with a protrusion 112, so that the compartment 110 is axially inserted into the base 130 through the tapering structure 111, and the protrusion 112 is provided circumferentially (e.g., ...). Figure 6 They are connected together in the X and / or Y directions as shown.

[0067] like Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the protrusion 112 includes a stop structure 1121 and a plug-in structure 1122 located on opposite sides of the stop structure 1121, so that the protrusion 112 is plugged into the base 130 through the plug-in structure 1122, and the stop structure 1121 limits the base 130 in the circumferential direction.

[0068] like Figures 2 to 4 As shown, in some embodiments of this utility model, the interior of the silo body 110 is provided with an anti-rotation rib 113, and the bearing member 120 is provided with an anti-rotation groove 1202. The anti-rotation rib 113 is embedded in the anti-rotation groove 1202 so that the bearing member 120 and the silo body 110 are relatively fixed in the circumferential direction.

[0069] In addition, in other embodiments of this utility model, those skilled in the art can also use other methods to fix the load-bearing member 120 and the chamber 110 in the circumferential direction as needed, such as screw connection, snap connection, adhesive bonding, etc.

[0070] like Figure 2 As shown, in some embodiments of this utility model, the height of the inner bottom surface of the bearing member 120 gradually decreases towards the outlet 1201, so that the coffee beans in the bearing member 120 can be discharged from the outlet 1201 under their own weight.

[0071] like Figures 2 to 4 As shown, in some embodiments of this utility model, a fixing post 121 is provided in the middle of the supporting member 120. The bean hopper 100 also includes an umbrella-shaped member 150 disposed in the hopper body 110, and the umbrella-shaped member 150 is inserted into the fixing post 121.

[0072] Those skilled in the art will understand that when a user puts coffee beans into the chamber 110, some coffee beans will fall into the umbrella-shaped component 150 and be bounced back into the chamber 110 by the conical upper surface of the umbrella-shaped component 150, so that the coffee beans fall in a stepped manner, reducing the impact of the coffee beans on the chamber 110, thereby reducing the noise when the user puts in the coffee beans.

[0073] like Figures 2 to 4 As shown, in some embodiments of this utility model, the base 130 includes a collar 131 sleeved on the outside of the closing structure 111. The top end of the collar 131 is provided with a clearance notch 1311 for avoiding the protrusion 112. The collar 131 is provided with slots 1312 that are adapted to the protrusion 112 at both ends of the clearance notch 1311 in the circumferential direction, so that one of the two slots 1312 is inserted into the protrusion 112 when the base 130 opens the discharge port 1201, and the other of the two slots 1312 is inserted into the protrusion 112 when the base 130 covers the discharge port 1201.

[0074] Continue reading Figures 2 to 4 In some embodiments of this utility model, the base 130 may also include a baffle 132, on which at least one material discharge hole 1321 is provided.

[0075] like Figures 5 to 8 As shown, the discharge hole 1321 can also rotate relative to the bearing member 120 to a position that is misaligned with the discharge port 1201 in order to cover the discharge port 1201.

[0076] like Figure 9 and Figure 10 As shown, the discharge hole 1321 can be rotated relative to the bearing member 120 to a position aligned with the discharge port 1201 in order to open the discharge port 1201.

[0077] like Figure 2 , Figure 3 , Figures 7 to 10As shown, in some embodiments of the present invention, the baffle 132 is provided with a receiving groove 1322 with an opening facing the bearing member 120 at its center to accommodate the weighing module 140, and the weighing module 140 abuts against the bearing member 120.

[0078] from Figure 7 As can be seen from the figure, in some embodiments of this utility model, the baffle 132 is provided with a clearance opening (not marked in the figure) on the peripheral wall of the receiving groove 1322 to avoid the wires of the weighing module 140.

[0079] like Figure 2 , Figure 3 and Figures 7 to 10 As shown, in some embodiments of this utility model, the base 130 further includes an inner ring 133 located inside the collar 131, and a baffle 132 is disposed at the top of the inner ring 133 so that the baffle 132 is located inside the constriction structure 111 and slides in contact with or gap fits with the bearing member 120.

[0080] like Figures 5 to 10 As shown, in the assembled state, the closing structure 111 of the compartment 110 is located between the collar 131 and the inner ring 133 of the base 130.

[0081] Of course, in other embodiments of this utility model, those skilled in the art may omit the inner ring 133 as needed, and extend the closing structure 111 downward to a position that abuts against or gap-fits the baffle 132.

[0082] from Figures 2 to 4 As can be seen from the above, in some embodiments of this utility model, there are two discharge ports 1201 and two discharge holes 1321, and they are centrally symmetrical with respect to the rotation axis φ of the hopper 110 and the base 130, respectively.

[0083] like Figures 2 to 4 As shown, in some embodiments of this utility model, the bean hopper 100 may also include a locking pin 160 and a spring 170, which are used to lock the base 130 and the hopper body 110 to the position where the discharge port 1201 is covered.

[0084] like Figure 3 , Figures 7 to 10 As shown, in some embodiments of this utility model, the closing structure 111 is provided with a receiving cavity 1111 with an opening facing the base 130. The locking pin 160 and the spring 170 are both arranged in the receiving cavity 1111, and the locking pin 160 is located on the side of the spring 170 closer to the base 130.

[0085] like Figure 3As shown, in some embodiments of this utility model, the top wall of the receiving cavity 1111 is provided with a limiting post (not marked in the figure) to limit the spring 170 and prevent the spring 170 from moving in the horizontal direction (in the use state). The top of the locking pin 160 is provided with an upward-opening insertion groove 161, which is inserted into the spring 170, thereby limiting the horizontal displacement of the locking pin 160 by the spring 170.

[0086] like Figure 4 As shown, in some embodiments of this utility model, a locking groove 1301 is provided on the base 130.

[0087] like Figure 7 As shown, when the base 130 and the hopper 110 are in a position where the outlet 1201 is covered, the locking pin 160 is inserted into the locking groove 1301 to prevent the base 130 and the hopper 110 from rotating relative to each other, thereby ensuring that the coffee beans in the bean hopper 100 will not leak out before the weighing is finished.

[0088] like Figure 2 , Figures 4 to 6 As shown, in some embodiments of this utility model, a snap-fit ​​structure 1313 is provided on the outer side of the collar 131 so that the bean hopper 100 is snapped onto the body 200 of the coffee machine 001 through the snap-fit ​​structure 1313.

[0089] Furthermore, although not shown in the figure, the coffee machine 001 in this invention has a mounting cavity on its body 200 for avoiding and mounting the bean hopper 100. The peripheral wall of the mounting cavity is provided with a snap-fit ​​structure for snapping the snap-fit ​​structure 1313 on the snap-fit ​​collar 131, so that the bean hopper 100 can be snapped onto the body 200 through the snap-fit ​​structure 1313 and the snap-fit ​​structure.

[0090] In some embodiments of this utility model, the snap-fit ​​structure 1313 is a protrusion 112 structure, and the snap-fit ​​mating structure is a groove structure.

[0091] In other embodiments of this utility model, those skilled in the art may, as needed, set the snap-fit ​​structure 1313 as a groove structure and the snap-fit ​​mating structure as a protrusion 112 structure.

[0092] Furthermore, after the bean hopper 100 is installed on the machine body 200, the weighing module 140 is electrically connected to the machine body 200 so that the controller on the machine body 200 can obtain the weight weighed by the weighing module 140 and control the display screen to display it.

[0093] The following reference Figures 5 to 10 The following describes in detail the usage of the bean hopper 100 in some embodiments of this utility model.

[0094] First, along Figure 6 The X-direction rotation of the chamber 110 shown in the figure causes the chamber 110 to rotate relative to the base 130 to a position where the discharge port 1201 is blocked (e.g., Figures 6 to 8 (As shown).

[0095] Then, add coffee beans into the bean hopper 100. When the weight displayed on the screen reaches the weight required by the user, stop adding coffee beans.

[0096] Finally, along Figure 6 The Y-direction rotation of the chamber 110 shown in the figure causes the chamber 110 to rotate relative to the base 130 to the position where the discharge port 1201 is opened (as shown in the figure). Figures 9 to 10 (As shown), simply let the coffee beans in the bean hopper 100 leak out.

[0097] Based on the foregoing description, those skilled in the art will understand that the coffee machine 001 of this utility model can detect the weight of the coffee beans on the supporting component 120, thereby enabling the user to add an appropriate amount of coffee beans into the bean hopper 100, avoiding adding too many or too few coffee beans into the bean hopper 100.

[0098] It should be noted that although the supporting component 120 cannot bear the weight of all the coffee beans in the bean hopper 100 due to the presence of the discharge port 1201, the weight of the coffee beans required for making coffee does not need to be very precise. Therefore, even if the weight of the coffee beans weighed by the coffee machine 001 of this utility model is inaccurate, it will not affect the user's judgment on whether there are enough coffee beans added to the bean hopper 100.

[0099] Furthermore, such as Figure 11 and Figure 12 As shown, in other embodiments illustrated therein, those skilled in the art may, as needed, make the weighing module 140 include a connection terminal 141 and provide a magnetic attraction member 1411 on the connection terminal 141 so that the connection terminal 141 is electrically connected to the body 200 of the coffee machine 001 by magnetic attraction.

[0100] The magnetic attraction component 1411 can be a magnet, and the body 200 is provided with a magnetic attraction mating component adapted to the magnet. The magnetic attraction mating component can be a magnet or a component that can be attracted by a magnet (such as an iron block).

[0101] Those skilled in the art will understand that the magnetic connection terminal 141 of the weighing module 140 facilitates the installation and removal of the bean hopper 100 by the user, thus improving the user experience.

[0102] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.
