Description

Technical Field

[0001] This application relates to the technical field of coffee machines, and in particular to an extraction mechanism and a capsule coffee machine. Background Technology

[0002] As living standards improve, people's demands for capsule coffee machines are becoming increasingly diversified. Currently, drawer-type coffee machines are very popular among consumers because they are compatible with various sizes of coffee capsules and allow users to fill them with coffee grounds themselves.

[0003] Currently, the extraction mechanism in existing capsule coffee machines, as shown in patent document CN202222162003.8, includes a linkage assembly comprising a rotating shaft mounted on a pressing head support, a pressing push rod rotatably connected to the shaft, a pressing handle mounted on the pressing push rod, and connecting rods connecting the two sides of the pressing push rod to the two sides of the pressing head. When the pressing head needs to be moved downwards, the user presses the pressing handle to rotate it, which drives the pressing head downwards via the pressing push rod and connecting rods, thereby compressing the capsule drawer and puncturing the capsule to create conditions for subsequent extraction. However, in this structural design, the force applied to the pressing handle directly drives the pressing head downwards, resulting in a pressing effect that is directly proportional to the applied force. This leads to problems such as excessive downward and upward pressure on the pressing handle, affecting the user experience. Furthermore, this design restricts the pressing handle to directly above the extraction mechanism, limiting the overall structural layout of the capsule coffee machine and resulting in a relatively simple design, making it difficult to meet the market's demand for product diversification and differentiation. Utility Model Content

[0004] In view of this, it is necessary to provide an extraction mechanism and capsule coffee machine that can solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] An extraction mechanism, comprising:

[0007] support;

[0008] An extraction chamber is detachably connected to the support, and the extraction chamber encloses a receiving cavity for containing a capsule.

[0009] An extraction pusher assembly is movably connected to the support for opening / closing the receiving cavity, and when the extraction pusher assembly closes the receiving cavity, the extraction pusher assembly is capable of extracting the capsule located in the receiving cavity;

[0010] A gear transmission assembly is rotatably mounted on the bracket. The gear transmission assembly includes a driving gear and a driven gear. The driving gear meshes with the driven gear and is connected to the extraction push plate assembly. The number of teeth of the driving gear is set to Z1, the number of teeth of the driven gear is set to Z2, and Z2 > Z1.

[0011] The pressure rod assembly is connected to the drive gear transmission and is used to provide driving force for the rotation of the drive gear on the bracket.

[0012] Understandably, the lever assembly drives the gear transmission assembly, transmitting power to the extraction pusher assembly, thereby controlling the opening and closing of the extraction chamber. This gear transmission assembly uses a design where the driven gear has more teeth than the driving gear, amplifying the input force applied by the user to the lever assembly before transmitting it to the extraction pusher assembly. Therefore, the user only needs to apply a small force when operating the lever assembly to generate a large driving force for the extraction pusher assembly, making the opening and closing of the extraction chamber easy and effortless, thus improving the user experience. Furthermore, the installation position of the lever assembly is no longer limited to directly above the extraction mechanism, breaking through the space constraints at the top of the extraction mechanism and providing more design freedom for the overall shape of the capsule coffee machine. This helps to achieve product diversification and differentiation, better meeting market demands.

[0013] In one embodiment, the transmission ratio between the driven gear and the driving gear is set to 30:14.

[0014] In one embodiment, the driven gear is configured as a sector gear.

[0015] Understandably, by setting the driven gear to a sector-shaped structure, the overall volume and material usage of the driven gear are effectively reduced, which not only lowers the manufacturing cost of the driven gear but also helps to reduce the overall volume of the extraction mechanism.

[0016] In one embodiment, the driven gear can abut against the bracket to limit the rotation angle of the driven gear when it rotates on the bracket, so as to control the movement stroke of the extraction pusher assembly when closing the receiving cavity.

[0017] It is understandable that the support and the driven gear form a mechanical limiting structure by mutual contact, which limits the maximum rotation angle of the driven gear on the support and controls the movement stroke of the pressure rod assembly when it drives the extraction push plate assembly to close the receiving cavity, preventing excessive compression due to excessive stroke and avoiding structural damage.

[0018] In one embodiment, the driven gear has an abutment surface, and the bracket has a limiting surface that can abut against the abutment surface.

[0019] In one embodiment, the pressure bar assembly includes a pressure bar and a pressure bar shaft, one end of which is connected to the pressure bar in a circumferentially limiting manner;

[0020] The other end of the pressure rod shaft is inserted into the drive gear to limit the circumferential movement of the pressure rod shaft and the drive gear; and the pressure rod shaft is also fixedly connected to the drive gear.

[0021] Understandably, the plug-in joint structure between the pressure rod shaft and the drive gear facilitates the assembly of the pressure rod shaft onto the drive gear and improves the positional accuracy of the pressure rod shaft during assembly.

[0022] In one embodiment, the drive gear has multiple threaded holes;

[0023] The extraction mechanism also includes multiple connectors, each of which corresponds to a threaded hole, and the connectors are screwed into the corresponding threaded holes after passing through the pressure rod shaft.

[0024] Understandably, the connector passes through the pressure rod shaft and is threaded to the drive gear, thus facilitating the assembly connection between the pressure rod shaft and the drive gear.

[0025] In one embodiment, the pressure bar assembly further includes a decorative element fitted onto the pressure bar shaft to cover it.

[0026] Understandably, covering the pressure rod shaft with decorative parts can improve the overall appearance and aesthetics of the extraction mechanism.

[0027] In one embodiment, the extraction mechanism further includes a main shaft and a main shaft drive sleeve, the main shaft being rotatably mounted on the bracket and connected to the driven gear drive;

[0028] The main shaft drive sleeve is fitted onto the main shaft and is circumferentially limited by the main shaft. Furthermore, the main shaft drive sleeve is connected to the extraction push plate assembly in a driving connection.

[0029] This application also claims protection for a capsule coffee machine, including the extraction mechanism described above.

[0030] Due to the application of the above solution, this application has the following advantages compared with the prior art:

[0031] The extraction mechanism and capsule coffee machine claimed in this application transmit power to the extraction pusher assembly via a lever assembly driving a gear transmission assembly, thereby controlling the opening and closing of the extraction chamber. This gear transmission assembly employs a design where the number of teeth on the driven gear is greater than that on the driving gear, amplifying the input force applied by the user to the lever assembly before transmitting it to the extraction pusher assembly. Therefore, the user only needs to apply a small force when operating the lever assembly to generate a large driving force for the extraction pusher assembly, making the opening and closing of the extraction chamber easy and effortless, thus improving the user experience. Furthermore, the installation position of the lever assembly is no longer limited to directly above the extraction mechanism, overcoming the space constraints at the top of the extraction mechanism and providing greater design freedom for the overall shape of the capsule coffee machine. This helps to achieve product diversification and differentiation, better meeting market demands. Attached Figure Description

[0046] The extraction mechanism 100 claimed in this application is used in a capsule coffee machine (not shown) to extract from capsules (not shown). It should be noted that the extraction mechanism 100 is not limited to capsule coffee machines; it can also be used in other beverage equipment to extract tea powder, fruit juice powder, etc., contained in capsules, which will not be elaborated upon here.

[0047] like Figures 1 to 7 As shown, the extraction mechanism 100 provided in this application includes a support 10, an extraction chamber 20, an extraction pusher assembly 30, a gear transmission assembly 40, and a pressure rod assembly 50. The extraction chamber 20 is detachably connected to the support 10, and the extraction chamber 20 encloses a receiving cavity 201 for receiving a capsule. The extraction pusher assembly 30 is movably connected to the support 10 for opening / closing the receiving cavity 201. When the extraction pusher assembly 30 closes the receiving cavity 201, the extraction pusher assembly 30 can press against the capsule located in the receiving cavity. The capsule in cavity 201 is used for extraction; the gear transmission assembly 40 is rotatably mounted on the support 10. The gear transmission assembly 40 includes a driving gear 41 and a driven gear 42. The driving gear 41 and the driven gear 42 mesh with each other and are connected to the extraction push plate assembly 30. The number of teeth of the driving gear 41 is set to Z1, the number of teeth of the driven gear 42 is set to Z2, and Z2 > Z1; the pressure rod assembly 50 is connected to the driving gear 41 and is used to provide driving force for the rotation of the driving gear 41 on the support.

[0048] As can be seen from the above, the extraction mechanism 100 of this application drives the gear transmission assembly 40 through the pressure rod assembly 50, transmitting power to the extraction push plate assembly 30, thereby controlling the opening and closing of the accommodating cavity 201. The gear transmission assembly 40 employs a design where the number of teeth on the driven gear 42 is greater than that on the driving gear 41, amplifying the input force applied by the user to the pressure rod assembly 50 before transmitting it to the extraction push plate assembly 30. Therefore, when operating the pressure rod assembly 50, the user only needs to apply a small force to achieve a large driving force for the extraction push plate assembly 30, making the opening and closing of the extraction chamber 20 easy and effortless, thus improving the user experience. Furthermore, the installation position of the pressure rod assembly 50 is no longer limited to directly above the extraction mechanism 100, breaking through the limitations of the top space of the extraction mechanism 100, providing more design freedom for the overall shape of the capsule coffee machine, helping to achieve product diversification and differentiation, and better meeting market demands.

[0049] like Figure 1 As shown, in one embodiment, the extraction chamber 20 and the support 10 are slidably connected. Specifically, the support 10 has a groove 11, in which the extraction chamber 20 is slidably installed and can move in and out of the working position by horizontal sliding. It is understood that in other embodiments, the extraction chamber 20 and the support 10 can also be connected by a snap-fit ​​method, which will not be elaborated here.

[0050] like Figure 1 , Figure 7 As shown, in one embodiment, the extraction pusher assembly 30 includes an extraction disc support 31, an extraction disc 32, and a disc coating 33. The extraction disc 32 is fixed on the extraction disc support 31, and the disc coating 33 covers the extraction disc 32. When the extraction pusher assembly 30 closes the receiving cavity 201, the disc coating 33 and the extraction chamber 20 are sealed.

[0051] like Figure 1 As shown, in one embodiment, the driven gear 42 is configured as a sector gear. That is, by configuring the driven gear 42 as a sector structure, this embodiment effectively reduces the overall volume and material usage of the driven gear 42, which not only reduces the manufacturing cost of the driven gear 42, but also helps to reduce the overall volume of the extraction mechanism 100.

[0052] like Figure 1 , Figure 6 As shown, in one embodiment, the transmission ratio between the driven gear 42 and the driving gear 41 is set to 30:14. It is understood that in other embodiments, this transmission ratio can also be set to different values ​​such as 20:10 or 25:15, depending on actual needs, to meet different transmission requirements.

[0053] like Figure 6As shown, in one embodiment, the driven gear 42 can abut against the bracket 10 to limit the rotation angle of the driven gear 42 when it rotates on the bracket 10, thereby controlling the travel of the extraction pusher assembly 30 when closing the receiving cavity 201. In other words, in this embodiment, the bracket 10 and the driven gear 42 form a mechanical limiting structure through mutual abutment, which limits the maximum rotation angle of the driven gear 42 on the bracket 10 and controls the travel of the pressure rod assembly 50 when it drives the extraction pusher assembly 30 to close the receiving cavity 201, preventing excessive pressure due to excessive travel and avoiding structural damage.

[0054] Specifically, the driven gear 42 has an abutment surface 421, and the bracket 10 has a limiting surface 12, which can abut against the abutment surface 421.

[0055] like Figure 1 , Figure 7 As shown, in one embodiment, the pressure rod assembly 50 includes a pressure rod 51 and a pressure rod shaft 52. One end of the pressure rod shaft 52 is connected to the pressure rod 51 in a circumferentially limiting manner; the other end of the pressure rod shaft 52 is inserted into the drive gear 41 to circumferentially limit the pressure rod shaft 52 and the drive gear 41; furthermore, the pressure rod shaft 52 is also fixedly connected to the drive gear 41. In other words, the insertion-fitting structure of the pressure rod shaft 52 and the drive gear 41 in this embodiment facilitates the assembly of the pressure rod shaft 52 onto the drive gear 41 and improves the positional accuracy of the pressure rod shaft 52 during assembly onto the drive gear 41.

[0056] like Figure 1 As shown, in one embodiment, the drive gear 41 has multiple threaded holes 411; the extraction mechanism 100 also includes multiple connectors 60, each corresponding to one of the multiple threaded holes 411, and the connector 60 is screwed into the corresponding threaded hole 411 after passing through the pressure rod shaft 52. That is, in this embodiment, the connector 60 passes through the pressure rod shaft 52 and is threadedly connected to the drive gear 41. This arrangement facilitates the assembly and connection between the pressure rod shaft 52 and the drive gear 41.

[0057] like Figure 1 , Figure 7As shown, in one embodiment, the pressure rod assembly 50 further includes a decorative element 53, which is fitted onto the pressure rod shaft 52 to cover it. In other words, this embodiment uses the decorative element 53 to cover the pressure rod shaft 52, thus improving the overall appearance and aesthetics of the extraction mechanism 100. In this embodiment, the decorative element 53 includes a pressure rod shaft sleeve 531 and a sleeve decorative piece 532. The pressure rod shaft sleeve 531 is fitted onto the pressure rod shaft 52, and a bolt 54 passes through the sleeve and is threadedly connected to the pressure rod shaft 52, thereby fixing the sleeve 531 to the shaft 52. The sleeve decorative piece 532 is installed on the sleeve 531, further serving a decorative and covering function.

[0058] like Figure 1 , Figure 7 As shown, in one embodiment, the extraction mechanism 100 further includes a main shaft 71 and a main shaft drive sleeve 72. The main shaft 71 is rotatably mounted on the bracket 10 and is drivenly connected to the driven gear 42. The main shaft drive sleeve 72 is fitted onto the main shaft 71 and circumferentially limited by the main shaft 71. Furthermore, the main shaft drive sleeve 72 is drivenly connected to the extraction pusher plate assembly 30. In this embodiment, the driven gear 42 is fitted onto the main shaft 71 and circumferentially limited by the main shaft 71.

[0059] like Figure 7 As shown, in one embodiment, the extraction mechanism 100 further includes a connecting rod 81 and a connecting rod pin 82. The connecting rod pin 82 passes through the main shaft transmission sleeve 72 and one end of the connecting rod 81, and the two ends of the connecting rod pin 82 extending out of the main shaft transmission sleeve 72 are respectively limited by retaining rings 83 fitted on the connecting rod pin 82, thereby realizing the hinge connection between the connecting rod 81 and the main shaft transmission sleeve 72. Here, the other end of the connecting rod 81 is provided with a rotating part 811, and the connecting rod 81 is rotatably connected to the extraction disc support 31 through the rotating part 811.

[0060] like Figure 6 As shown, in one embodiment, the extraction mechanism 100 further includes a micro switch 90, which is mounted on the bracket 10. A trigger part 721 is provided on the main shaft drive sleeve 72, and the trigger part 721 can rotate together with the main shaft drive sleeve 72. The micro switch 90 is located on the rotation path of the trigger part 721. When the user operates the pressure lever 51 to completely close the extraction chamber 20, the main shaft drive sleeve 72 rotates to a predetermined angle, and the trigger part 721 then activates the micro switch 90, causing it to generate a corresponding electrical signal. This electrical signal is used to control the start and stop of the capsule coffee machine's extraction system, thereby ensuring that the extraction operation only occurs when the extraction chamber 20 is completely sealed.

[0061] When the extraction mechanism 100 of this application is in operation, the user presses the pressure lever assembly 50 to rotate it counterclockwise by approximately 90°, which in turn drives the drive gear 41 to rotate counterclockwise by approximately 90°. The drive gear 41 meshes with the driven gear 42, causing the driven gear 42 to rotate clockwise by approximately 45°. During this process, the driven gear 42 drives the main shaft 71 to rotate, which in turn drives the main shaft transmission sleeve 72 to rotate. Finally, the connecting rod 81 drives the extraction pusher assembly 30 to move downward, compressing and sealing the coffee capsule in the extraction chamber 20. Afterward, the high-pressure water supplied by the water pump (not shown in the figure) flows through the water connector 34 and the internal hollow needle 35 on the extraction pusher assembly 30 and is injected into the coffee capsule, completing the high-pressure extraction of the coffee powder. When the pressure lever assembly 50 rotates clockwise by approximately 90°, the extraction chamber 20 can be opened accordingly.

[0062] This application also provides a capsule coffee machine, including the extraction mechanism 100 described above.

[0063] 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.

[0064] 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 scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
