Description

Technical Field

[0001] This utility model relates to the technical field of beverage brewing, and more particularly to a beverage brewing mechanism and beverage brewing equipment having such a mechanism. Background Technology

[0002] As people's living standards continue to improve, beverage brewing machines, such as coffee machines, have entered thousands of households. To facilitate consumer use, technicians in related fields are constantly developing beverage brewing machines with new functions to meet the needs of different consumers.

[0003] The beverage brewing machine has a brewing unit, which includes a brewing chamber and a brewing plug. The brewing plug can move into the brewing chamber to press powder, such as coffee powder, inside the chamber and seal the chamber to brew the beverage.

[0004] In related brewing units, the brewing chamber and the brewing plug typically share a single motor. Since one motor needs to drive both the brewing chamber and the brewing plug, this requires multiple transmission mechanisms. Consequently, the brewing unit is larger and more complex in structure, thus increasing manufacturing costs.

[0005] Furthermore, most existing fully automated coffee brewing devices are quite large and complex in structure, and even smaller devices are limited to brewing small cups of coffee or are single-function brewing systems. Therefore, they cannot meet diverse coffee brewing needs.

[0006] The brewing unit of this coffee machine features a large brewing stopper to support the pressure exerted by the brewing piston on the brewer during the coffee brewing process. This brewing stopper is not only bulky and difficult to manufacture, but also places high demands on its installation on the frame. Furthermore, the coffee machine's excessive pursuit of small size results in a very small brewer capacity, only suitable for brewing small single-cup coffees and single-function coffee brewing.

[0007] Therefore, it is necessary to provide a beverage brewing apparatus and beverage brewing equipment that can solve the above-mentioned shortcomings. Utility Model Content

[0046] In combination with Figure 5 and Figure 6 shown, wherein Figure 5 for Figure 1 a perspective view of the brewer rotating seat 22 of the beverage brewing mechanism 100 shown, Figure 6 for Figure 1 a perspective view of the brewer rotating seat 22 of the beverage brewing mechanism 100 shown, Figure 4The assembly structure of the skeleton 5 is shown in the cross-sectional view. The brewing device 2 comprises a brewing chamber assembly 21, a brewing rotor seat 22, a brewing rotor driving gear 23 and a brewing motor driving assembly 24. The brewing rotor seat 22 is rotatably mounted on the skeleton 5, and the brewing chamber assembly 21, the brewing rotor driving gear 23 and the brewing motor driving assembly 24 are all mounted on the brewing rotor seat 22. The brewing chamber assembly 21 is provided with a brewing chamber 20 for receiving powder. For example, the brewing rotor seat 22 can be provided with a brewing chamber buckle slot 223 for buckling connection with the brewing chamber assembly 21.

[0047] In combination with Figure 7 and Figure 8 as shown, Figure 7 as shown, Figure 1 The brewing chamber assembly 21 of the beverage brewing mechanism 100 is shown in the cross-sectional view, Figure 8 as shown, Figure 7 The first transmission assembly 240 in the brewing chamber assembly 21 of the beverage brewing mechanism 100 is shown in the perspective view.

The dreg pushing plate 214 can be provided with a fluid passage for discharging the brewed beverage through the fluid passage.

[0048] The rack device 4 is connected with the powder pressing piston 11 and is arranged to drive the intermediate transmission gear 3 to rotate along with the back-and-forth movement of the powder pressing piston 11, so that the intermediate transmission gear 3 drives the brewing rotor driving gear 23 to rotate, and the rotation of the brewing rotor driving gear 23 drives the brewing device 2 to rotate.

[0049] In addition, the brewing chamber assembly 21 can be provided with a buckle 215, so as to be buckled with the brewing chamber buckle slot 223 of the brewing rotor seat 22. In this way, the brewing chamber assembly 21 can be detached from the brewing rotor seat 22, facilitating cleaning.

[0050] In combination with Figure 9 as shown, Figure 9 A perspective assembly view of part of the structure of the beverage brewing mechanism 100 is provided in an embodiment of the present application, wherein the brewing device 2 is in a high-pressure brewing state. When the brewing device 2 is rotated to align the opening of the brewing chamber 20 with the powder pressing piston 11, the piston motor driving assembly 12 drives the powder pressing piston 11 to extend into the brewing chamber 20 to press the powder contained in the brewing chamber 20. The bottom of the powder pressing piston 11 can be provided with a water outlet mesh, and hot water finally enters the brewing chamber 20 from the water outlet mesh. When the powder pressing piston 11 extends into the brewing chamber 20, the brewing chamber 20 is sealed, so that hot water can be input into the brewing chamber 20 at high pressure, and then the powder is brewed to form beverage.

[0051] In the beverage brewing mechanism 100 of the above embodiment, the powder pressing piston device 1 and the brewer device 2 are two independent units, and each of the powder pressing piston device 1 and the brewer device 2 has a motor driving assembly, i.e., the piston motor driving assembly 12 and the brew motor driving assembly 24, so that the structure of the beverage brewing mechanism 100 is relatively compact, and the operation is relatively simple.

[0052] In an embodiment, the powder pressing piston device 1 and the brewer device 2 are combined Figures 4 to 5 As shown in the figure, the skeleton 5 is provided with a rotating sliding groove 51 and a rotating center hole 52, and the brewer rotating seat 22 is provided with a rotating seat sliding block 221 and a rotating center column 222. The brewer rotating seat 22 is located on one side of the skeleton 5, the rotating center column 222 is inserted into the rotating center hole 52, and the rotating seat sliding block 221 is located in the rotating sliding groove 51 and is arranged to be able to slide along the rotating sliding groove 51. The skeleton 5 can be part of the shell structure of the beverage brewing equipment, used to play a supporting role. The rotating sliding groove 51 matches the outer shape of the rotating seat sliding block 221 to guide the rotating motion of the rotating seat sliding block 221. The rotating center column 222 can be cylindrical, and the rotating center hole 52 can be a corresponding circular hole. The depth of the rotating sliding groove 51 (the thickness of the part of the skeleton 5 where the rotating sliding groove 51 is opened) can be equal to or greater than the thickness of the rotating seat sliding block 221. In this way, stable rotating motion of the brewer rotating seat 22 relative to the skeleton 5 can be achieved.

[0053] In an embodiment, the brewer driving gear 23 is arranged on the other side of the skeleton 5 (not shown in the figure) and is connected with the brewer rotating seat 22, so as to rotatably mount the brewer rotating seat 22 on the skeleton 5. For example, the brewer driving gear 23 can be threadedly connected or snap connected with the brewer rotating seat 22, etc., so as to lock the brewer rotating seat 22 on the skeleton 5 and only allow rotating motion. The other side of the skeleton 5 is opposite to the aforementioned one side of the skeleton 5. In this way, both the connection and mounting of the brewer driving gear 23 and the brewer rotating seat 22 and the locking of the brewer rotating seat 22 on the skeleton 5 to prevent shaking during rotation can be achieved.

[0054] In an embodiment, the powder pressing piston device 1 and the brewer device 2 are combined Figures 4 to 5 As shown in the figure, the rotating sliding groove 51 is in a first circular arc shape with the rotating center hole 52 as the center, the rotating seat sliding block 221 is in a second circular arc shape with the rotating center column 222 as the center, and the brewer driving gear 23 is in a third circular arc shape with the rotating center column 222 as the center. The brewer driving gear 23 is provided with a plurality of gear teeth on the side facing the intermediate transmission gear 3, the gear teeth are arranged along the third circular arc shape, and are used to mesh with the intermediate transmission gear 3. In this way, the brewer driving gear 23 can be driven by the intermediate transmission gear 3 to rotate around the rotating center column 222, and then drive the entire brewer device 2 to rotate around the rotating center hole 52.

[0055] In an embodiment, in combination with Figures 1 to 3 As shown, the brewer drive gear 23 comprises a drive gear positioning slot 231, the axis of which is parallel to the axis of the brew chamber 20. The drive gear positioning slot 231 is used to play a guiding role to the rack device 4.

[0056] In combination with Figures 10 to 12 As shown, Figure 10 To Figure 1 As shown, the rack device 4 and the intermediate transition gear 3 of the beverage brewing mechanism 100 in the first state, Figure 11 As shown, Figure 10 As shown, the rack device 4 and the intermediate transition gear 3 of the beverage brewing mechanism 100 in the second state, Figure 12 As shown, Figure 10 As shown, the rack device 4 and the intermediate transition gear 3 of the beverage brewing mechanism 100 in the third state. The rack device 4 comprises a rack bar 40, which is provided with a plurality of rack teeth 41. The number of the plurality of rack teeth 41 is set such that, when the rack device 4 drives the intermediate transition gear 3 to rotate through the rack teeth 41, and in turn drives the brewer device 2 to rotate to align the opening of the brew chamber 20 with the powder pressing piston 11, the rack teeth 41 no longer mesh with the intermediate transition gear 3, and the rack bar 40 begins to be inserted into the drive gear positioning slot 231. Based on the above, the number of the plurality of rack teeth 41 is limited to complete a small angle rotation of the brewer device 2, for example, any rotation angle within the range of 25 to 45 degrees.

[0057] During the period when the rack bar 40 is inserted into the drive gear positioning slot 231, the drive gear positioning slot 231 is used to cooperate with the rack bar 40 to prevent the brewer device 2 from rotating. The intermediate transition gear 3 can comprise an intermediate large gear 30 and an intermediate small gear 31 fixedly connected thereto, which are coaxially arranged; thus, the rack teeth 41 can cooperate with the intermediate small gear 31, and the intermediate large gear 30 cooperates with the brewer drive gear 23. In this way, the guiding role of the drive gear positioning slot 231 to the rack bar 40 can be achieved, and during this guiding, the rack device 4 no longer drives the intermediate transition gear 3 to rotate.

[0058] In an embodiment, in combination with Figures 7 to 8As shown, the first transmission assembly 240 comprises the brewing chamber screw 211, a first bevel gear 212 and a second bevel gear 213. The dregs pushing plate 214 is mounted on the top end of the brewing chamber screw 211, and the second bevel gear 213 is sleeved on the brewing chamber screw 211 and engaged with the external thread of the brewing chamber screw 211 through the internal thread. The second bevel gear 213 is engaged with the first bevel gear 212, the brewing motor driving assembly 24 drives the first bevel gear 212 to rotate, the first bevel gear 212 drives the second bevel gear 213 to rotate, and the second bevel gear 213 drives the brewing chamber screw 211 to move back and forth along the axis of the brewing chamber screw 211. The rotation axis of the first bevel gear 212 can be arranged at a right angle to the rotation axis of the second bevel gear 213. The first transmission assembly 240 and the dregs pushing plate 214 are both arranged in the brewing chamber assembly 21. The brewing chamber assembly 21 can also be provided with a structure for preventing the brewing chamber screw 211 from rotating, so as to drive the brewing chamber screw 211 to move back and forth along the axis of the brewing chamber screw 211 when the second bevel gear 213 rotates. In this way, the dregs pushing plate 214 can be driven to move by the brewing motor driving assembly 24 and the first transmission assembly 240, so as to realize the operations such as extrusion of powder, pushing out of dregs after brewing of beverage, etc.

[0059] In an embodiment, in combination with Figures 10 to 12 As shown, the rack device 4 comprises a rack rod 40, a limiting stopper 42, a touching piece 43, a limiting switch 44, a pause position switch 45, a first pause position switch reset stopper 46 and a second pause position switch reset stopper 47. The rack rod 40 is provided with rack teeth 41, which are engaged with the intermediate transition gear 3. The limiting switch 44, the pause position switch 45, the first pause position switch reset stopper 46 and the second pause position switch reset stopper 47 are fixedly arranged relative to the rack rod 40. The limiting stopper 42 is fixedly mounted on the rack rod 40, and the touching piece 43 is rotatably mounted on the rack rod 40. For example, the touching piece 43 can comprise a touching block and a rod connected with the touching block, the touching block is used to contact with the pause position switch 45, and the rod is used to contact with the first pause position switch reset stopper 46 and the second pause position switch reset stopper 47, and drive the touching block to rotate.

[0060] Specifically in combination with Figure 9 And Figure 10 As shown, when the rack device 4 moves away from the intermediate transition gear 3 with the powder pushing piston 11, the touching piece 43 actuates the pause position switch 45, so that the pause position switch 45 controls the piston motor driving assembly 12 to pause. In this way, the non-rotation of the brewer device 2 can be realized by pausing the piston motor driving assembly 12, thereby allowing the brewer device 2 to perform the operation of discharging dregs.

[0061] Specifically in combination with Figure 11As shown, when the rack device 4 moves further away from the intermediate gear 3 to the farthest position, the second pause position switch reset post 47 contacts the contact piece 43, and the contact piece 43 is rotated to a position where it cannot touch the pause position switch 45; the limit post 42 is used to contact the limit switch 44 to limit the maximum distance of the piston motor drive assembly 12 driving the powder compression piston 11 away from the intermediate gear 3. In this way, the maximum stroke of the powder compression piston 11 movement can be controlled.

[0062] Specifically combined Figure 12 As shown, when the rack device 4 moves away from the intermediate gear 3 to the farthest position towards the intermediate gear 3, the first pause position switch reset post 46 contacts the contact piece 43, and the contact piece 43 is rotated to a position where it can touch the pause position switch 45. In this way, the reset of the contact piece 43 can be realized, so that when the rack device 4 moves away from the intermediate gear 3 next time, the contact piece 43 can repeatedly actuate the pause position switch 45.

[0063] In an embodiment, combined Figure 1 and Figure 13 As shown, Figure 13 It is a first state of the beverage brewing mechanism 100 provided by an embodiment of the utility model, and the first state is the initial state and the powder loading state. The beverage brewing mechanism 100 further comprises a residue cake pushing plate 6. The residue cake pushing plate 6 is installed on the framework 5 and is arranged adjacent to the opening of the brewing cavity 20.

[0064] The piston motor drive assembly 12 is arranged to pause when driving the powder compression piston 11 to move away from the opening of the brewing cavity 20 by a certain distance. The brewing motor drive assembly 24 is arranged to drive the residue cake pushing plate 214 to move to push the residue cake out of the brewing cavity 20 during the pause of the piston motor drive assembly 12. In this way, the non-rotation of the brewer device 2 can be realized by pausing the piston motor drive assembly 12, thereby allowing the brewer device 2 to perform the residue cake discharging operation.

[0065] During the resumption of the piston motor drive assembly 12 to continue driving the powder compression piston 11 to move away from the brewing cavity 20, the brewer device 2 is driven by the intermediate gear 3 to rotate in the reverse direction, so that the residue cake located outside the brewing cavity 20 is pushed away from the brewer device 2 by the residue cake pushing plate 6.
