Description

Technical Field

[0001] This invention relates to the field of coffee machines, and in particular to an automatic coffee powder dispensing device for coffee machines. Background Technology

[0002] Coffee machines are typically equipped with a grinder, whose core function is to grind coffee beans into coffee powder suitable for extraction. Collecting the coffee powder output from the grinder is a necessary preliminary step for subsequent coffee extraction. However, in traditional coffee machine designs, although the grinding process itself is automated, it lacks the function of automatically controlling the start or stop of the grinder's output of coffee powder, resulting in a low level of automation. Summary of the Invention

[0003] Therefore, it is necessary to provide an automatic coffee powder dispensing device for coffee machines, addressing the issues of traditional coffee machines lacking the function of automatically controlling the start or stop of the grinder to output coffee powder and having a low degree of automation.

[0004] An automatic coffee powder dispensing device for a coffee machine includes: a support assembly; a grinding assembly disposed on the support assembly and having a powder dispensing channel; a moving assembly movably disposed on the support assembly and capable of moving relative to the support assembly; an extraction hopper disposed on the moving assembly and having an extraction chamber; a baffle structure movably disposed on the grinding assembly and capable of rotating relative to the grinding assembly, the baffle structure being capable of rotating relative to the grinding assembly by at least a first angle and a second angle, wherein the powder dispensing channel is opened when the baffle structure rotates by the first angle and is closed when the baffle structure rotates by the second angle; a pushing block is formed on the moving assembly, wherein when the moving assembly moves relative to the support assembly, the pushing block abuts against the baffle structure and drives the baffle structure to rotate relative to the grinding assembly.

[0005] This application discloses an automatic coffee powder dispensing device for a coffee machine. A push block is formed on a moving component, and a baffle structure is formed at the powder dispensing channel. When the moving component moves relative to the supporting component and drives the extraction hopper to the powder receiving position, the push block abuts against the baffle structure and automatically pushes the baffle structure to rotate to a first angle. This opens the powder dispensing channel without additional operation, allowing coffee powder to fall smoothly into the extraction chamber. When powder dispensing is complete, as the moving component drives the extraction hopper to move in the opposite direction, the baffle structure loses the external force of the push block and automatically rotates back to a second angle under the action of gravity or a return mechanism, thus reliably closing the powder dispensing channel. This design incorporates a structure for automatically opening and closing the powder dispensing channel into the necessary structural design of the moving component driving the extraction hopper to dispense powder, eliminating the need for additional drive components, reducing energy waste, and achieving a high degree of automation. The automatic coffee powder dispensing device of this application improves the overall automation level and operational reliability of the product, effectively preventing coffee powder from spilling when not in a powder receiving state.

[0006] In one embodiment, the moving component has at least a first position and a second position when moving relative to the supporting component. When the moving component is in the first position and the second position, the pushing block abuts against the baffle structure. When the moving component is between the first position and the second position, the moving component is configured to move towards the direction closer to the second position, and the baffle structure rotates towards the direction of opening the powder outlet channel. Conversely, when the moving component is configured to move towards the direction closer to the first position, the baffle structure rotates towards the direction of closing the powder outlet channel. By ensuring that the pushing block remains in contact with the baffle structure while the moving component moves between the first and second positions, stable control of the opening and closing state of the powder outlet channel is achieved. Specifically, when the moving component moves to the first position, the pushing block just contacts the baffle structure; when the moving component moves from the first position to the second position, the pushing block continuously applies a thrust to the baffle structure, driving it to rotate smoothly and open the powder outlet channel; when the moving component moves to the second position, the powder outlet channel is opened to its maximum extent; during the process of the moving component moving back from the second position to the first position, the baffle structure automatically rotates and resets due to gravity or the action of a reset structure, thus closing the powder outlet channel. This design enables automatic coffee grounds dispensing.

[0007] In one embodiment, when the moving component is located between the first position and the second position and moves towards the second position, the extraction hopper moves towards the direction that aligns the extraction chamber and the dispensing channel. Conversely, when the moving component is located between the first position and the second position and moves towards the first position, the extraction hopper moves towards the direction that deviates the extraction chamber from the dispensing channel. As the moving component reaches the first position and moves towards the second position, two processes occur simultaneously: the push block drives the baffle structure to gradually open the dispensing channel, and the extraction hopper gradually aligns its extraction chamber with the dispensing channel. Specifically, the degree of opening of the dispensing channel ensures that the amount of coffee powder output can be received by the extraction chamber, allowing the opening degree of the dispensing channel to match the alignment degree of the extraction chamber in real time. This design achieves coffee dispensing when the extraction hopper is in position and stopping dispensing when the extraction hopper is removed, preventing coffee powder spillage. Since the extraction hopper will move to the bottom of the tamping component for tamping as the moving component moves, the movement of the moving component is a necessary step. This design does not require the extraction chamber and the powder outlet channel to be perfectly aligned. Instead, the moving component can pick up coffee powder during the movement, thus effectively improving the powder picking efficiency.

[0008] In one embodiment, the support assembly has an installation port, and the grinding assembly includes a grinder and a powder outlet tube. The grinder is mounted on the support assembly, and the powder outlet tube is mounted on the support assembly and mates with the installation port. The powder outlet tube has a powder outlet channel, a powder outlet, and an opening, both of which communicate with the powder outlet channel. The opening is located on the side of the powder outlet tube, and the powder outlet is located at the bottom of the powder outlet tube. A baffle structure is mounted on the powder outlet tube and located at the opening. The mating of the powder outlet tube with the installation port allows coffee powder output from the powder outlet tube to fall into the extraction hopper below the installation port. The powder outlet located at the bottom of the powder outlet tube ensures that the coffee powder falls smoothly due to gravity. The opening on the side of the powder outlet tube provides the necessary rotation space for the baffle structure, allowing the baffle structure to open and close effectively by rotation, achieving reliable sealing and opening of the powder outlet channel.

[0009] In one embodiment, a support shaft is formed on the outer side of the powder outlet tube. The baffle structure includes a baffle body and a transmission block. The baffle body is movably mounted on the support shaft and can open or close the powder outlet channel. The transmission block is mounted on the support shaft and / or the baffle body. The pushing block can abut against the transmission block and drive the transmission block and the baffle body to rotate together relative to the grinding assembly. By movably mounting the baffle body on the support shaft, the baffle body can rotate around the support shaft as a fulcrum to achieve the function of opening or closing the powder outlet channel. By abutting against the transmission block, the horizontal thrust of the pushing block is effectively converted into the rotational motion of the baffle body during the movement of the moving assembly toward the second position, ensuring the reliability of the baffle body's rotation.

[0010] In one embodiment, the baffle body includes a support block and a baffle portion. The support block is mounted on the support shaft, and the baffle portion is mounted on the support block and inclined relative to the support block. The baffle portion is located at the opening and can open or close the powder dispensing channel. Compared to a design where the baffle portion and support block are horizontal, this design, by having the baffle portion inclined relative to the support block, allows for closing the powder dispensing channel with a smaller rotation amplitude of the baffle body. This design facilitates a shorter distance that the moving component needs to travel during the process of driving the baffle body to fully open or close the powder dispensing channel, improving the efficiency of coffee powder collection. It also makes the overall structure more compact. The center of gravity of the baffle body is on the baffle portion, allowing the baffle body to automatically close the powder dispensing channel under gravity.

[0011] In one embodiment, the system further includes a fixing block and a torsion spring. The fixing block is disposed on the powder outlet pipe, and the torsion spring is sleeved on the support shaft. One end of the torsion spring engages with the fixing block, and the other end engages with the baffle body. By engaging with the fixing block and the baffle body respectively, the torsion spring generates torque as the baffle body rotates to open the powder outlet channel. This torque actively drives the baffle body to automatically reset and close the air outlet channel.

[0012] In one embodiment, the transmission block has an abutting plane on the side facing the push block, and the push block has an abutting ramp on the side facing the transmission block. When the moving component moves relative to the support component, the abutting ramp can abut against the abutting plane to drive the baffle structure to rotate relative to the grinding component. The abutting ramp and the abutting plane drive the baffle structure to move. Specifically, when the moving component moves to the first position, the abutting ramp and the abutting plane are in line contact. During the movement of the moving component from the first position to the second position, the line contact between the abutting ramp and the abutting plane drives the baffle structure to rotate. During this process, the abutting plane gradually rotates towards the abutting ramp, and at the second position, the abutting plane and the abutting ramp are completely abutted. This design ensures that the push block can drive the baffle structure to rotate during the movement of the moving component.

[0013] In one embodiment, a tamping assembly is further included, which is disposed on a support assembly and adjacent to the grinding assembly. The moving assembly, when moving relative to the support assembly, has at least two positions: a second position and a third position. When the moving assembly is in the second position, the extraction chamber is aligned with the coffee dispensing channel; when the moving assembly is in the third position, the extraction chamber is aligned with the tamping assembly. When the moving assembly is in the second position, the extraction chamber is aligned with the coffee dispensing channel, completing automatic coffee grounds dispensing. When the moving assembly continues to move to the third position, the extraction chamber is aligned with the tamping assembly, allowing for immediate tamping. This design automates the coffee grounds dispensing and tamping operations, fulfilling the preconditions for coffee extraction.

[0014] In one embodiment, the tamping assembly includes a drive motor, a screw, and a tamper. The drive motor is mounted on the support assembly, the screw is mounted on the drive motor, and the tamper is driven by the screw. Under the control of the screw, the tamper can move relative to the support assembly, and the direction of movement of the tamper is perpendicular to the direction of movement of the moving assembly. Driven by the screw, the tamper can move precisely in a direction perpendicular to the movement of the moving assembly. When the moving assembly delivers the extraction hopper carrying coffee grounds to the third position, the tamping assembly automatically performs a vertical tamping operation. This design compresses the coffee grounds into a cake, preparing it for extraction. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-15 As shown, this embodiment discloses an automatic coffee powder dispensing device for a coffee machine, including: a support assembly 1; a grinding assembly 2, which is disposed on the support assembly 1 and has a powder dispensing channel 201; a moving assembly 3, which is movably disposed on the support assembly 1 and is movable relative to the support assembly 1; an extraction hopper 4, which is disposed on the moving assembly 3 and has an extraction chamber 401; and a baffle structure 5, which is movably disposed on the grinding assembly 2. The baffle structure 5 is rotatable relative to the grinding assembly 2. The baffle structure 5 is rotatable relative to the grinding assembly 2 by at least a first angle and a second angle. When the baffle structure 5 rotates to the first angle, the powder outlet channel 201 is opened. When the baffle structure 5 rotates to the second angle, the baffle structure 5 closes the powder outlet channel 201. A push block 31 is formed on the moving assembly 3. When the moving assembly 3 moves relative to the supporting assembly 1, the push block 31 can abut against the baffle structure 5 and drive the baffle structure 5 to rotate relative to the grinding assembly 2.

[0020] This application discloses an automatic coffee powder dispensing device for a coffee machine. A push block 31 is formed on a moving component 3, and a baffle structure 5 is formed at the powder dispensing channel 201. When the moving component 3 moves relative to the supporting component 1 and drives the extraction hopper 4 to the powder receiving position, the push block 31 abuts against the baffle structure 5 and automatically pushes the baffle structure 5 to rotate to a first angle. This opens the powder dispensing channel 201 without additional operation, allowing coffee powder to fall smoothly into the extraction chamber 401. When powder dispensing is complete, as the moving component 3 drives the extraction hopper 4 to move in the opposite direction, the baffle structure 5 loses the external force of the push block and automatically rotates back to a second angle under the action of gravity or a return mechanism, thus reliably closing the powder dispensing channel 201. This design incorporates a structure for automatically opening and closing the powder dispensing channel 201 into the necessary structural design of the moving component 3 driving the extraction hopper 4 to dispense powder, eliminating the need for additional drive components, reducing energy waste, and achieving a high degree of automation. The automatic coffee powder dispensing device of this application improves the overall automation level and operational reliability of the product, effectively preventing coffee powder from spilling when not in a powder receiving state.

[0021] like Figure 1-4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: when the moving component 3 moves relative to the supporting component 1, it has at least a first position and a second position; when the moving component 3 is in the first position and the second position, the pushing block 31 abuts against the baffle structure 5; when the moving component 3 is between the first position and the second position, the moving component 3 is configured to move towards the direction closer to the second position, and the baffle structure 5 rotates towards opening the powder outlet channel 201; and when the moving component 3 is configured to move towards the direction closer to the first position, the baffle structure 5 rotates towards closing the powder outlet channel 201. By ensuring that the pushing block 31 remains in contact with the baffle structure 5 while the moving component 3 moves between the first position and the second position, stable control of the opening and closing state of the powder outlet channel 201 is achieved. Specifically, when the moving component 3 moves to the first position, the pushing block 31 just contacts the baffle structure 5; when the moving component 3 moves from the first position to the second position, the pushing block 31 continuously applies a pushing force to the baffle structure 5, driving it to rotate smoothly and open the powder dispensing channel 201; when the moving component 3 moves to the second position, the powder dispensing channel 201 is opened to its maximum extent; when the moving component 3 moves from the second position back to the first position, the baffle structure 5 automatically rotates and resets due to gravity or the action of the reset structure, thus closing the powder dispensing channel 201. This design achieves the function of automatically dispensing coffee powder.

[0022] like Figure 1-4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: when the moving component 3 is located between the first position and the second position and moves towards the direction closer to the second position, the extraction hopper 4 moves towards the direction that aligns the extraction chamber 401 and the powder outlet channel 201; when the moving component 3 is located between the first position and the second position and moves towards the direction closer to the first position, the extraction hopper 4 moves towards the direction that deviates the extraction chamber 401 from the powder outlet channel 201. When the moving component 3 reaches the first position and moves towards the second position, two processes are simultaneously performed: the push block 31 drives the baffle structure 5 to gradually open the powder outlet channel 201, and the extraction hopper 4 is driven to gradually align its extraction chamber 401 with the powder outlet channel 201. Specifically, the degree of opening of the powder outlet channel 201 ensures that the amount of coffee powder output can be received by the extraction chamber 401, so that the degree of opening of the powder outlet channel 201 matches the degree of alignment of the extraction chamber 401 in real time. This design ensures that coffee grounds are dispensed as soon as the extraction hopper 4 is in place and stop dispensing when the hopper 4 is removed, preventing coffee grounds from spilling. Since the extraction hopper 4 will move with the moving component 3 to the bottom of the tamping component 8 for tamping, the movement of the moving component 3 is a necessary step. This design does not require the extraction chamber 401 and the dispensing channel 201 to be perfectly aligned. Instead, the moving component 3 can collect coffee grounds during its movement, thus effectively improving the efficiency of coffee grounds collection.

[0023] like Figure 4-5 and Figure 9-11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support component 1 is provided with an installation port 101; the grinding component 2 includes a grinder 21 and a powder outlet tube 22; the grinder 21 is disposed on the support component 1; the powder outlet tube 22 is disposed on the support component 1 and cooperates with the installation port 101; the powder outlet tube 22 is provided with a powder outlet channel 201; the powder outlet tube 22 is provided with a powder outlet 202 and an opening 203; both the powder outlet 202 and the opening 203 communicate with the powder outlet channel 201; the opening 203 is located on the side of the powder outlet tube 22; the powder outlet 202 is located at the bottom of the powder outlet tube 22; and the baffle structure 5 is disposed on the powder outlet tube 22 and located at the opening 203. Through the cooperation of the powder outlet tube 22 with the installation port 101, the coffee powder output from the powder outlet tube 22 can fall into the extraction hopper 4 below the installation port 101. The coffee powder outlet 202 located at the bottom of the powder outlet tube 22 ensures that the coffee powder can fall smoothly under gravity. The opening 203 located on the side of the powder outlet tube 22 provides the necessary rotation space for the baffle structure 5, allowing the baffle structure 5 to be opened and closed effectively by rotation, thus achieving reliable sealing and opening of the powder outlet channel 201.

[0024] like Figure 4-11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a support shaft 221 is formed on the outer side of the powder outlet pipe 22; the baffle structure 5 includes a baffle body 51 and a transmission block 52; the baffle body 51 is movably disposed on the support shaft 221; the baffle body 51 can open or close the powder outlet channel 201; the transmission block 52 is disposed on the support shaft 221 and / or the baffle body 51; and the pushing block 31 can abut against the transmission block 52 and drive the transmission block 52 and the baffle body 51 to rotate together relative to the grinding assembly 2. Because the baffle body 51 is movably disposed on the support shaft 221, it can rotate around the support shaft 221 as a fulcrum, thereby realizing the function of opening or closing the powder outlet channel 201. Because the pushing block 31 abuts against the transmission block 52, the horizontal thrust of the pushing block 31 is effectively converted into the rotational action of the baffle body 51 during the movement of the moving assembly 3 toward the second position, ensuring the reliability of the rotation of the baffle body 51.

[0025] like Figure 9 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the baffle body 51 includes a support block 511 and a baffle part 512. The support block 511 is disposed on the support shaft 221, and the baffle part 512 is disposed on the support block 511 and is inclined relative to the support block 511. The baffle part 512 is located at the opening 203 and can open or close the powder dispensing channel 201. Compared to a design where the baffle part 512 and the support block 511 are horizontal, this design, by having the baffle part 512 inclined relative to the support block 511, can close the powder dispensing channel 201 with a smaller rotation range of the baffle body 51. This design is beneficial for achieving a shorter distance that the moving component 3 needs to move during the process of driving the baffle body 51 to rotate to fully open or fully close the powder dispensing channel 201, thus improving the efficiency of receiving coffee powder. Furthermore, it makes the overall structure more compact. The center of gravity of the baffle body 51 is on the baffle part 512, which enables the baffle body 51 to automatically close the powder outlet channel 201 under the action of gravity.

[0026] like Figure 3 , Figure 5 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further includes a fixing block 6 and a torsion spring 7. The fixing block 6 is disposed on the powder outlet pipe 22, and the torsion spring 7 is sleeved on the support shaft 221. One end of the torsion spring 7 cooperates with the fixing block 6, and the other end of the torsion spring 7 cooperates with the baffle body 51. Through the cooperation of the two ends of the torsion spring 7 with the fixing block 6 and the baffle body 51 respectively, the torsion spring 7 generates torque during the rotation of the baffle body 51 to open the powder outlet channel 201. This torque has a positive driving effect on the automatic reset of the baffle body 51 and the closing of the air outlet channel.

[0027] like Figure 3 , Figure 10 and Figure 12-13 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the transmission block 52 has an abutting plane 501 on the side facing the pushing block 31, and the pushing block 31 has an abutting inclined surface 301 on the side facing the transmission block 52. When the moving component 3 moves relative to the supporting component 1, the abutting inclined surface 301 can abut against the abutting plane 501 to drive the baffle structure 5 to rotate relative to the grinding component 2. The abutting inclined surface 301 and the abutting plane 501 can drive the baffle structure 5 to move. Specifically, when the moving component 3 moves to the first position, the abutting inclined surface 301 and the abutting plane 501 are in line contact. During the process of the moving component 3 moving from the first position to the second position, the line contact between the abutting inclined surface 301 and the abutting plane 501 will drive the baffle structure 5 to rotate. During this process, the abutting plane 501 gradually rotates and moves closer to the abutting inclined surface 301, and at the second position, the abutting plane 501 and the abutting inclined surface 301 are completely abutted. This design ensures that the moving component 3 can drive the baffle structure 5 to rotate during movement by pushing the block 31.

[0028] like Figure 14 and Figure 15 As shown, in addition to the features of the above embodiments, this embodiment further specifies that it includes a tamping component 8, which is disposed on the support component 1 and adjacent to the grinding component 2. When the moving component 3 moves relative to the support component 1, it has at least a second position and a third position. When the moving component 3 is in the second position, the extraction chamber 401 is aligned with the powder outlet channel 201. When the moving component 3 is in the third position, the extraction chamber 401 is aligned with the tamping component 8. When the moving component 3 is in the second position, the extraction chamber 401 is aligned with the powder outlet channel 201, completing automatic powder dispensing. When the moving component 3 continues to move to the third position, the extraction chamber 401 is aligned with the tamping component 8, allowing for immediate tamping. This design automates the powder dispensing and tamping operations, fulfilling the preconditions for coffee extraction.

[0029] like Figure 14 and Figure 15 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the tamping assembly 8 includes a drive motor 81, a screw 82, and a tamper 83. The drive motor 81 is mounted on the support assembly 1, the screw 82 is mounted on the drive motor 81, and the tamper 83 is pulverizedly connected to the screw 82. The tamper 83 can move relative to the support assembly 1 under the control of the screw 82, and the direction of movement of the tamper 83 is perpendicular to the direction of movement of the moving assembly 3. Driven by the screw 82, the tamper 83 can move precisely in a direction perpendicular to the movement of the moving assembly 3. When the moving assembly 3 delivers the extraction hopper 4 carrying coffee powder to the third position, the tamping assembly 8 can automatically perform a vertical tamping operation. This design can compress coffee powder into a cake, preparing it for extraction.

[0030] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
