[0009] When in the first transmission position, the driven rotating component drives between the active rotating component and the extraction mechanism; when in the second transmission position, the driven rotating component drives between the active rotating component and the grinding mechanism.

[0010] In one embodiment, the driven rotation assembly includes a first driven rotation member and a second driven rotation member;

[0011] The switching component is controlled to cause the first driven rotating member to switch between a first separation position and a first transmission position. In the first transmission position, the first driven rotating member is driven between the driving rotating member and the extraction mechanism. In the first separation position, the first driven rotating member is separated from at least one of the driving rotating member and the extraction mechanism.

[0012] The switching component is also controlled to switch the second driven rotating member between a second disengaged position and a second driven position. In the second driven position, the second driven rotating member drives between the driving rotating member and the grinding mechanism.

[0014] The second driven rotating member has a second magnetic attraction part, and the electromagnetic component is controlled to attract the second magnetic attraction part so that the second driven rotating member switches from one of the second separation position and the second transmission position to the other of the second separation position and the second transmission position.

[0015] In one embodiment, the electromagnetic component includes a first electromagnetic element and a second electromagnetic element, wherein the first electromagnetic element is controlled to be attracted to a first magnetic attraction portion, and the second electromagnetic element is controlled to be attracted to a second magnetic attraction portion.

[0016] In one embodiment, the extraction and grinding switching mechanism further includes a first support, on which a first positioning part and a second positioning part are provided. The first positioning part cooperates with the first electromagnetic component for positioning, such that the position of the first electromagnetic component corresponds to the position of the first driven rotating component. The second positioning part cooperates with the second electromagnetic component for positioning, such that the position of the second electromagnetic component corresponds to the position of the second driven rotating component.

[0017] In one embodiment, the first positioning part includes a first positioning groove, and the first electromagnetic element is positioned within the first positioning groove; and / or

[0023] The second bracket has a second axial guide hole through which the rotation shaft of the second driven rotating member passes. The second axial guide hole is used to guide the second driven rotating member to move axially.

[0024] Another aspect of this application provides a coffee machine including the extraction and grinding switching mechanism described in any of the above embodiments.

[0025] The aforementioned extraction and grinding switching mechanism and coffee machine selectively switch the driven rotary component to the first transmission position and the second transmission position through the switching component, thereby selectively driving the extraction mechanism and the grinding mechanism.

[0037] See Figure 1 and Figure 2 , Figure 1 This invention provides a schematic diagram of a portion of the structure of a coffee machine according to one embodiment of the present application. Figure 2 It shows Figure 1 The diagram shown shows a portion of the coffee machine's structure without the first and second supports. An embodiment of this application provides an extraction and grinding switching mechanism 100, which includes a rotary drive 10, an active rotary component 20, a driven rotary component 30, and a switching component 40.

[0038] The extraction and grinding switching mechanism 100 in this embodiment is used to switch between driving the extraction mechanism 200 and the grinding mechanism 300. Driving the extraction mechanism 200 refers to driving its operation, which can be a part or all of its actions. Typically, the actions of the extraction mechanism 200 include at least tamping and brewing. In this embodiment, driving the extraction mechanism 200 can be a tamping action, specifically driving the tamping mechanism. The tamping mechanism's movement is not limited to vertical downward pressing; it can also be rotation or a combination of other actions. Similarly, driving the grinding mechanism 300 refers to driving its operation. In this embodiment, driving the grinding mechanism 300 can be driving the grinding blade to rotate.

[0039] The rotary drive 10 is connected to the active rotary component 20 to drive the active rotary component 20 to rotate. The switching component 40 is controlled to cause the driven rotary component 30 to switch between a first transmission position and a second transmission position.

[0040] When in the first transmission position, the driven rotating component 30 drives between the active rotating component 20 and the extraction mechanism 200. When in the second transmission position, the driven rotating component 30 drives between the active rotating component 20 and the grinding mechanism 300.

[0041] Therefore, by selectively switching the driven rotary component 30 to the first transmission position and the second transmission position through the switching component 40, the extraction mechanism 200 and the grinding mechanism 300 are selectively driven. Whether in the first transmission position or the second transmission position, the driven rotary component 30 can be connected to the active rotary component 20 connected to the same rotary drive component 10. Therefore, it is no longer necessary to drive the extraction mechanism 200 and the grinding mechanism 300 separately through multiple independent rotary drive components 10, which reduces the number of rotary drive components 10 and lowers the cost of the coffee machine.

[0042] Specifically, in the embodiments of this application, the driven rotating assembly 30 includes a first driven rotating member 31. The switching assembly 40 is controlled to make the first driven rotating member 31 switch between a first separation position and a first transmission position. In the first transmission position, the first driven rotating member 31 transmits between the active rotating member 20 and the extraction mechanism 200. In the first separation position, the first driven rotating member 31 is separated from at least one of the active rotating member 20 and the extraction mechanism 200.

[0043] The driven rotating assembly 30 also includes a second driven rotating member 32. The switching assembly 40 is controlled to cause the second driven rotating member 32 to switch between a second disengaged position and a second transmission position. In the second transmission position, the second driven rotating member 32 transmits power between the driving rotating member 20 and the grinding mechanism 300. In the second disengaged position, the second driven rotating member 32 is separated from at least one of the driving rotating member 20 and the grinding mechanism 300.

[0044] By setting the driven rotating component 30 to include a first driven rotating element 31 and a second driven rotating element 32, so as to control the extraction mechanism 200 and the grinding mechanism 300 respectively, the switching structure of the switching component 40 is simplified, making the switching process simpler and more reliable.

[0045] In some other embodiments, the driven rotating component 30 may also be controlled as a whole by the switching component 40. For example, the switching component 40 may drive the driven rotating component 30 to swing to switch between a first transmission position and a second transmission position.

[0046] Furthermore, the switching component 40 includes an electromagnetic component 41, and the first driven rotating member 31 has a first magnetic attraction portion 311. The electromagnetic component 41 is controlled to attract the first magnetic attraction portion 311 so that the first driven rotating member 31 switches from one of the first separation position and the first transmission position to the other of the first separation position and the first transmission position.

[0047] By setting the switching component 40 to controllably attract the first magnetic suction part 311 through the electromagnetic component 41, the way to switch the first driven rotating member 31 from one of the first separation position and the first transmission position to the other is simple, and the electric control method of the electromagnetic component 41 is also simple.

[0048] Specifically, when the electromagnetic component 41 is energized, it can generate a magnetic attraction force to attract the first magnetic attraction part 311. When the electromagnetic component 41 is de-energized, it can not generate a magnetic attraction force and therefore cannot attract the first magnetic attraction part 311.

[0049] In other embodiments, different magnitudes of magnetic attraction force can be generated by controlling the amount of current supplied to the electromagnetic component 41, thereby achieving adsorption or non-adsorption of the first magnetic attraction part 311.

[0050] Similarly, the second driven rotating member 32 may also have a second magnetic attraction part, and the electromagnetic component 41 is controlled to attract the second magnetic attraction part so that the second driven rotating member 32 switches from one of the second separation position and the second transmission position to the other of the second separation position and the second transmission position.

[0051] By setting the switching component 40 to controllably attract the second magnetic part through the electromagnetic component 41, the second driven rotating member 32 can be switched from one of the second separation position and the second transmission position to the other of the second separation position and the second transmission position in a simple way, and the electromagnetic component 41 can also be controlled electrically.

[0052] Specifically, when the electromagnetic component 41 is energized, it can generate a magnetic attraction force to attract the second magnetic part. When the electromagnetic component 41 is de-energized, it can not generate a magnetic attraction force and therefore cannot attract the second magnetic part.

[0053] In other embodiments, different magnitudes of magnetic attraction force can be generated by controlling the amount of current supplied to the electromagnetic component 41, thereby achieving the adsorption or non-adsorption of the second magnetic attraction part.

[0054] Furthermore, the electromagnetic component 41 includes a first electromagnetic element 411 and a second electromagnetic element 412. The first electromagnetic element 411 is controlled to be attracted to the first magnetic attraction part 311, and the second electromagnetic element 412 is controlled to be attracted to the second magnetic attraction part.

[0055] By setting the first electromagnetic component 411 and the second electromagnetic component 412 to attract the first magnetic part 311 and the second magnetic part respectively, the method of controlling the electromagnetic component 41 to attract both the first magnetic part 311 and the second magnetic part is simplified. This allows the electromagnetic component 41 to independently and controllably attract the first magnetic part 311 and the second magnetic part, which simplifies the structure of the electromagnetic component 41 and improves the reliability of the attraction of the first magnetic part 311 and the second magnetic part.

[0056] In other situations, the electromagnetic component 41 can also function as a whole, and can be controlled to attract the first magnetic part 311 and the second magnetic part respectively.

[0057] In some embodiments, the extraction and grinding switching mechanism 100 further includes a first support 50, on which a first positioning part 51 and a second positioning part 52 are provided. The first positioning part 51 is positioned in cooperation with the first electromagnetic component 411 so that the position of the first electromagnetic component 411 corresponds to the position of the first driven rotating component 31. The second positioning part 52 is positioned in cooperation with the second electromagnetic component 412 so that the position of the second electromagnetic component 412 corresponds to the position of the second driven rotating component 32.

[0058] By setting the first positioning part 51 and the second positioning part 52 to position the first electromagnetic component 411 and the second electromagnetic component 412 respectively, the positional deviation of the first electromagnetic component 411 and the second electromagnetic component 412 is prevented, thereby improving the reliability of the corresponding adsorption of the first electromagnetic component 411 and the first magnetic attraction part 311, as well as the reliability of the corresponding adsorption of the second electromagnetic component 412 and the second magnetic attraction part.

[0059] Specifically, the first electromagnetic component 411 and the second electromagnetic component 412 can be disposed directly opposite to the first magnetic attraction portion 311 and the second magnetic attraction portion, respectively. In the specific embodiments of this application, the first electromagnetic component 411 and the second electromagnetic component 412 can be disposed along the first magnetic attraction portion 311 and the second magnetic attraction portion, respectively. Figure 1 The Z-direction is set directly opposite.

[0060] In a specific embodiment of this application, the first positioning part 51 includes a first positioning groove, and the first electromagnetic element 411 is positioned in the first positioning groove.

[0061] The first positioning groove can form a positioning along the outer periphery of the first electromagnetic component 411, thus improving the reliability of positioning.

[0062] Specifically, the inner contour shape of the first positioning groove can be adapted to the outer contour shape of the first electromagnetic component 411.

[0063] More specifically, the inner contour of the first positioning groove is cylindrical, and the outer contour of the first electromagnetic component 411 is cylindrical.

[0064] Similarly, the second positioning part 52 may also include a second positioning groove, and the second electromagnetic element 412 is positioned in the second positioning groove.

[0065] The second positioning groove can form a positioning along the outer periphery of the second electromagnetic component 412, thus improving the reliability of positioning.

[0066] Specifically, the inner contour shape of the second positioning groove can be adapted to the outer contour shape of the second electromagnetic component 412.

[0067] More specifically, the inner contour of the second positioning groove is cylindrical, and the outer contour of the second electromagnetic component 412 is cylindrical.

[0068] In other embodiments, the first positioning part 51 may also be a positioning protrusion to engage with the positioning groove on the first electromagnetic component 411 for positioning. Similarly, the second positioning part 52 may also be a positioning protrusion to engage with the positioning groove on the second electromagnetic component 412 for positioning.

[0069] In the embodiments of this application, the active rotating member 20 includes an active gear, the first driven rotating member 31 includes a first driven gear that can drive and cooperate with the active gear, and the second driven rotating member 32 includes a second driven gear that can drive and cooperate with the active gear.

[0070] The transmission method of setting up a drive gear and a driven gear to work together is simple and the transmission process is reliable.

[0071] It should be noted that, since the first driven gear needs to drive the driving gear and the extraction mechanism 200 in the first transmission position, one end of the extraction mechanism 200 can also be equipped with a corresponding driven wheel or rack, etc., as needed. Similarly, since the second driven gear also needs to drive the driving gear and the grinding mechanism 300 in the second transmission position, one end of the grinding mechanism 300 can also be equipped with a corresponding driven wheel or rack, etc., as needed.

[0072] In some embodiments, the switching component 40 is controlled to cause the first driven rotating member 31 to switch axially between a first transmission position and a first separation position.

[0073] Since both the active rotating component 20 and the first driven rotating component 31 are rotating components, they occupy a large radial space, while the axial space is sufficient. Therefore, by setting the switching component 40 to control the first driven rotating component 31 to switch between the first transmission position and the first separation position along the axial direction, the axial space can be fully utilized, and the movement of the first driven rotating component 31 is less affected by interference, thus improving the reliability of the movement.

[0074] In other embodiments, the switching component 40 is controlled to cause the second driven rotating member 32 to switch axially between the second driving position and the second disengaged position.

[0075] Similarly, since both the active rotating component 20 and the driven rotating component 32 are rotating components, they occupy a large radial space, while the axial space is sufficient. Therefore, by setting the switching component 40 to control the second driven rotating component 32 to switch between the second transmission position and the second separation position along the axial direction, the axial space can be fully utilized, and the movement of the second driven rotating component 32 is less affected by interference, thus improving the reliability of the movement.

[0076] Furthermore, the axial movement of the first driven rotating member 31 and the second driven rotating member 32 refers to the movement along... Figure 1 The Z-axis motion is shown.

[0077] In some embodiments, the extraction and grinding switching mechanism 100 further includes a second support 60, on which a first axial guide hole 61 is provided for the rotation shaft A1 of the first driven rotating member 31 to pass through. The first axial guide hole 61 is used to guide the first driven rotating member 31 to move axially.

[0078] By providing a first axial guide hole 61 on the second bracket 60 to guide the movement of the first driven rotating member 31, the smoothness and accuracy of the movement of the first driven rotating member 31 can be improved, thereby enhancing the control reliability of the switching component 40 on the first driven rotating member 31. For example, the first driven rotating member 31 can be guided to correspond to the position of the aforementioned first electromagnetic member 411.

[0079] It should be noted that the second bracket 60 can be an inner shell support bracket of the coffee machine, which can be connected to the outer shell of the coffee machine to support at least part of the structure of the extraction mechanism 200 and the grinding mechanism 300. Therefore, the reliability of the second bracket 60 can be improved, thereby improving the reliability of the guide.

[0080] Similarly, the second bracket 60 may also have a second axial guide hole 62 through which the rotation shaft A2 of the second driven rotating member 32 passes. The second axial guide hole 62 is used to guide the second driven rotating member 32 to move axially.

[0081] By providing a second axial guide hole 62 on the second bracket 60 to guide the movement of the second driven rotating member 32, the smoothness and accuracy of the movement of the second driven rotating member 32 can be improved, thereby enhancing the control reliability of the switching assembly 40 over the second driven rotating member 32.

[0082] Combination Figure 3In the embodiments of this application, the aforementioned first magnetic attraction part 311 can be specifically disposed at the end of the first driven rotating member 31 facing the first electromagnetic member 411 from the rotation axis A1, or it can be disposed inside the first driven rotating member 31. For example, the first magnetic attraction part 311 can be disposed inside the first driven gear. When the first magnetic attraction part 311 is disposed inside the first driven gear, the volume of the first magnetic attraction part 311 can be increased, thereby improving the reliability of magnetic attraction.

[0083] The aforementioned second magnetic attraction part can be specifically provided at the end of the rotation shaft A2 of the second driven rotating member 32 facing the second electromagnetic member 412, or it can be provided inside the second driven rotating member 32. For example, the second magnetic attraction part can be provided inside the second driven gear.

[0084] Based on the same inventive concept, this application also provides a coffee machine, including the extraction and grinding switching mechanism 100 in any of the above embodiments.

[0085] The coffee machine described above selectively switches the driven rotary component 30 to the first transmission position and the second transmission position via the switching component 40, thereby selectively driving the extraction mechanism 200 and the grinding mechanism 300. Whether in the first transmission position or the second transmission position, the driven rotary component 30 can be connected to the active rotary component 20 connected to the same rotary drive component 10. Therefore, it is no longer necessary to drive the extraction mechanism 200 and the grinding mechanism 300 separately through multiple independent rotary drive components 10, which reduces the number of rotary drive components 10 and lowers the cost of the coffee machine.

[0086] Furthermore, the extraction mechanism 200 includes a third driven gear, a nut, and a lead screw. When the first driven gear is in the first transmission position, it can be connected to the third driven gear, thereby driving the nut on the third driven gear to rotate. The screw cooperates with the lead screw to drive the lead screw to move axially to realize the powder pressing operation.

[0087] The bean grinding mechanism 300 includes a fourth driven gear 310 and a fifth driven gear 320. When the second driven gear is in the second transmission position, it can be connected to the fourth driven gear 310. The fourth driven gear 310 is connected to the fifth driven gear 320. The fifth driven gear 320 is connected to the grinding blade rotation shaft of the bean grinding mechanism 300, thereby driving the grinding blade to rotate to realize the bean grinding operation.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
