[0065] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0066] In order to solve the technical problems in the background technology, the embodiment of the present application provides a beverage brewing device. Figure 1 、 Figure 2 and Figure 3 The brewing device includes a first drive assembly 1, a liner 2, a funnel support assembly, a funnel assembly 21, a powder channel 7, a second drive assembly, a rotating door 9, a transmission shaft assembly and a brewing assembly.

[0067] The first driving assembly 1 is used to provide a first driving force, and the first driving assembly 1 can be a motor, and here the motor can be a motor having a motor body 102 and a first transmission gear 101. Of course, the first driving assembly 1 can also adopt other driving structures.

[0068] One end of the liner 2 is connected to the first drive assembly 1. For example, the liner 2 can be a cylindrical structure with openings at both ends. The top and bottom of the liner 2 have connecting portions for connection. The connecting portion at the top of the liner 2 can be detachably connected to the motor body 102 of the first drive assembly 1. The first transmission gear 101 can extend into the interior of the liner 2 through the opening at the top of the liner 2 and connect to the transmission shaft assembly.

[0069] One end of the funnel support assembly is connected to the other end of the liner 2, and together with the liner 2, a receiving cavity is formed. For example, the connection between the top end of the funnel support assembly and the bottom end of the liner 2 can be detachably connected by screws or the like. Both ends of the funnel support assembly are also open.

[0070] The funnel assembly 21 includes a powder bowl 2101, which may be provided with a handle for holding. The funnel assembly 21 is detachably mounted on the other end of the funnel support assembly. When the funnel assembly 21 is mounted on the funnel support assembly, the powder bowl 2101 receives the powder. The handle can be used to install and remove the funnel assembly 21.

[0071] The powder channel 7 has a powder inlet 701 and a powder outlet 703. The powder outlet 703 of the powder channel 7 is connected to the funnel support assembly for conveying powdered material to the coffee machine. The powder channel 7 can be a pipe with a certain curvature, and the powder inlet 701 can be higher than the powder outlet 703 to ensure smooth conveyance of the powdered material along the powder channel 7. The powder inlet 701 of the powder channel 7 can be connected to a bean grinder assembly. For example, if the powdered material is coffee powder, the coffee beans can be ground into powder in the bean grinder. The powdered material can enter the powder channel 7 through the powder inlet 701.

[0072] The second drive assembly is used to provide a second driving force, and the second drive assembly can be arranged on the liner 2. The second drive assembly can include a reduction motor having a second transmission gear 18. Of course, the second drive assembly can also adopt other structural forms.

[0073] The revolving door 9 is cylindrical and has openings at both ends. The revolving door 9 is disposed in the accommodating chamber and is connected to the second drive assembly. Specifically, the revolving door 9 can also be connected to the second transmission gear 18 and rotate under the action of the second drive force. A valve opening 902 is provided on the side wall of the revolving door 9 that passes through the side wall of the revolving door 9. Figure 6 and Figure 7 The rotating door 9 has a closed state and an open state. When the rotating door 9 is in the open state, the valve opening 902 is aligned with the powder outlet 703 of the powder channel 7, allowing the powder to pass through the valve opening 902 and fall into the powder bowl 2101. After the powder feeding is completed, the second drive assembly drives the rotating door 9 to rotate in the opposite direction, so that the rotating door 9 is in the closed state. At this time, the side wall of the rotating door 9 blocks the powder outlet 703 of the powder channel 7, preventing moisture from entering through the powder channel 7.

[0074] The transmission shaft assembly is disposed in the accommodating cavity, one end of the transmission shaft assembly is connected to the first driving assembly 1 , and at least a portion of the structure of the transmission shaft assembly can move up and down under the action of the first driving force.

[0075] The brewing assembly is located at the other end (the lower end) of the drive shaft assembly and moves up and down with the drive shaft assembly to compact the powder in the powder bowl 2101. Water for brewing coffee can enter the powder bowl 2101 through the brewing assembly to brew the compacted powder in the powder bowl 2101. The brewing assembly can be connected to an external water supply (e.g., a heat boiler assembly) via a pipe to allow water for brewing coffee to enter the brewing assembly. The water used for brewing coffee can be either cold or hot water.

[0076] The embodiment of the present application combines the transmission shaft assembly with the brewing head assembly and the powder channel 7, and sends the powder to the funnel assembly 21 in a relatively sealed cavity. The first drive assembly 1 is used to drive the transmission shaft assembly, so that the brewing head assembly can move up and down with the transmission shaft assembly to compress the powder in the funnel assembly 21. After the powder is compacted, water can be added to the brewing assembly to complete the brewing of coffee, realizing fully automatic powder compaction and brewing in one.

[0077] In some embodiments, combined Figure 9 and Figure 10 , the transmission shaft assembly includes an inner transmission shaft and an outer transmission shaft 6, one end (upper end) of the inner transmission shaft is connected to the first transmission gear 101 of the first drive assembly 1, and rotates under the driving action of the first transmission gear 101. For example, the upper end of the inner transmission shaft is provided with an arc-shaped transmission tooth 401 that cooperates with the first transmission gear 101. A ball bearing 3 can be provided between the inner transmission shaft and the motor body 102 to reduce the friction between the two and enhance service life. The inner transmission shaft can adopt a cylindrical structure, and the outer transmission shaft 6 can also adopt a cylindrical structure, and both ends of the inner transmission shaft and the outer transmission shaft 6 have open ends, which can facilitate the connection of the brewing component and the hot boiler component. For example, the hot boiler component can be connected to the brewing component through a water supply pipe.

[0078] Combine Figure 8 、 Figure 9 and Figure 10 The inner drive shaft has an external thread 402, and the outer drive shaft 6 has an internal thread 602, which mates with the inner drive shaft's external thread 402. The inner wall of the liner 2 is provided with a positioning bone 201 that protrudes from the inner wall of the liner 2. The positioning bone 201 can be arranged axially along the cylindrical liner 2. The outer wall of the outer drive shaft 6 is provided with a sliding groove 601, which mates with the positioning bone 201. When the inner drive shaft rotates, the sliding groove 601 slides along the positioning bone 201, allowing the outer drive shaft 6 to move upward or downward.

[0079] For example, rotation of the inner drive shaft's external transmission thread 402 causes the inner thread 602 of the outer drive shaft 6 to move up and down in coordination. Positioning bones 201 are provided at the bottom of the inner liner 2, interfacing with sliding grooves 601 on the outer side of the outer drive shaft 6. This allows the outer drive shaft 6 to rotate independently of the inner drive shaft during its up and down movement. A gasket 5 can also be placed between the inner and outer drive shafts 6 to reduce friction during rotational movement.

[0080] The up and down movement of the outer transmission shaft 6 is achieved through the cooperation between the inner transmission shaft and the outer transmission shaft 6 and the sliding cooperation between the outer transmission shaft 6 and the positioning bone 201 of the inner liner 2.

[0081] In some embodiments, combined Figure 2 The brewing device also includes a first switch 221 bracket 16, a first switch 221 and a second switch 222. The first switch 221 bracket 16 is arranged on the inner wall of the liner 2, and the first switch 221 and the second switch 222 are respectively arranged at the upper end and the lower end of the first switch 221 bracket 16.

[0082] The top end of the outer transmission shaft 6 is provided with a peripheral portion 603 protruding from the outer surface of the outer transmission shaft 6. The peripheral portion 603 triggers the first switch 221 and the second switch 222, respectively, to detect the position of the outer transmission shaft 6, and then determines the operation of the second drive assembly based on the position of the outer transmission shaft 6. That is, a first switch 221 bracket 16 is built on the inner lining 2, and a switch is respectively installed on the upper and lower sides of the first switch 221 bracket 16. The switches can be micro switches. When the outer transmission shaft 6 moves up and down, the peripheral portion 603 is used to trigger the first switch 221 or the second switch 222 of the first switch 221 bracket 16 to detect the movement trajectory of the outer transmission shaft 6.

[0083] The position of the outer transmission shaft 6 can be detected by the first switch 221 and the second switch 222 to determine the actions of other structural components when the outer transmission shaft 6 is located at different positions.

[0084] In some embodiments, the second drive assembly includes a second drive motor and a second transmission gear 18. Figure 11 The upper portion of the rotating door 9 is provided with a rotating lip 903 and a rotating tooth 901 that cooperates with the second transmission gear 18. The rotating tooth 901 can be provided along the upper outer peripheral surface of the rotating door 9, and the rotating tooth 901 does not go around the rotating door 9 in one circle.

[0085] Combine Figure 2The brewing device further includes a third switch 10, which is disposed at the bottom of the inner wall of the liner 2. The third switch 10 can also be a microswitch. When the rotating door 9 rotates until the rotating lip 903 triggers the third switch 10, the rotating door 9 is closed. When the rotating door 9 rotates until the rotating tooth 901 triggers the third switch 10, the rotating door 9 is opened. The third switch 10 determines the position of the rotating door 9, and thus the state of the rotating door 9.

[0086] In some embodiments, combined Figure 2 When the first drive assembly 1 drives the outer transmission shaft 6 upward to the periphery 603 and triggers the first switch 221, the first drive assembly 1 stops driving. The second transmission gear 18 drives the rotating door 9 to rotate by cooperating with the rotating teeth 901. When the rotating teeth 901 trigger the third switch 10, the second transmission gear 18 stops driving. After the powder filling is completed, the second transmission gear 18 drives the rotating door 9 to rotate in the opposite direction. When the rotating lip 903 triggers the third switch 10, the second transmission gear 18 stops driving. The first drive assembly 1 drives the outer transmission shaft 6 downward to the periphery 603 and triggers the second switch 222. The first drive assembly 1 stops driving. The linkage detection of the first switch 221 and the third switch 10 realizes the linkage between the first drive assembly and the second drive assembly.

[0087] In some embodiments, the brewing assembly includes a brewing head cover 8 and a filter sheet 20 .

[0088] The upper cover 8 of the brewing head has a water inlet 801. The upper cover 8 of the brewing head is connected to the other end (lower end) of the transmission shaft assembly and moves up and down with the transmission shaft assembly.

[0089] The filter 20 is arranged on the water outlet end of the brewing head cover 8. When the transmission shaft assembly moves downward, the filter 20 moves downward with the brewing head cover 8 to press the powder in the powder bowl 2101. Figure 5 , and the water for brewing coffee enters the brewing head cover 8 through the water inlet 801 and then enters the powder bowl 2101 to brew the powder after being pressed in the powder bowl 2101. A brewing head sealing ring 19 can be set between the filter 20 and the brewing head cover 8 to prevent water from leaking from the connection. The bottom of the filter 20 can also be provided with patterns for pressing powder, and the specific setting of the patterns can be set according to requirements. That is, the bottom of the external transmission shaft 6 can be equipped with a brewing assembly formed by the brewing head cover 8, the brewing head sealing ring 19, and the filter 20, and the water inlet 801 can be connected to an external heating boiler assembly to obtain water supply, forming a group of brewing components that can move up and down.

[0090] The powder in the powder bowl 2101 is compressed by the filter sheet 20 provided on the upper cover 8 of the brewing head, water for brewing coffee is introduced through the water inlet 801 of the brewing head upper cover 8, and the compressed powder is brewed to make coffee.

[0091] In some embodiments, combined Figure 12 and Figure 13 The funnel support assembly includes a funnel support upper cover 11 and a funnel support lower cover 12. One end (upper end) of the funnel support upper cover 11 is connected to the inner liner 2, and one end (upper end) of the funnel support lower cover 12 is connected to the other end (lower end) of the funnel support upper cover 11. The funnel support lower cover 12 is provided with an assembly portion that mates with the funnel assembly 21, so that the funnel assembly 21 can be detachably mounted on the funnel support lower cover 12. For example, the detachable mounting method of the funnel assembly 21 and the funnel support assembly can be used in a commonly used disassembly method for existing coffee machines, which will not be described in detail here.

[0092] In addition, combined Figure 2 A notch can be provided on the side of the funnel support upper cover 11, and the powder outlet 703 of the powder channel 7 can be installed at the notch position.

[0093] A vent hole 1101 is provided on the side of the funnel support upper cover 11, which communicates with the outside world. When the rotating door 9 is closed, the valve opening 902 faces the vent hole 1101 to keep the brewing device dry. When the rotating door 9 is closed, the valve opening 902 communicates with the vent hole 1101 to exhaust moisture from the compressed powder brewing device, and the rotating door 9 can block the powder outlet 703 of the air duct to prevent moisture from entering.

[0094] A funnel sealing ring can be provided at the bottom of the funnel bracket lower cover 12 to achieve sealing with the powder bowl 2101 of the funnel assembly 21, thereby preventing water from leaking from the connection between the funnel bracket lower cover 12 and the powder bowl 2101.

[0095] In some embodiments, combined Figure 12 and Figure 13 The funnel support assembly is equipped with a second switch 222 bracket 15, a push rod 14, a spring 13, and a fourth switch 223. The fourth switch 223 is located above the second switch 222 bracket 15. The push rod 14 is located on the second switch 222 bracket 15, and the spring 13 is sleeved on the push rod 14. When the funnel assembly 21 is installed on the funnel support assembly, the funnel assembly 21 pushes the push rod 14 upward and compresses the spring 13. When the funnel assembly 21 is in place, the top of the push rod 14 triggers the fourth switch 223. The fourth switch 223 detects whether the funnel assembly 21 is in place, facilitating the subsequent tamping and coffee brewing processes.

[0096] After the funnel assembly 21 is removed from the floor support assembly, the spring 13 extends and pushes the top rod 14 downward, and the top rod 14 releases the triggering effect on the fourth switch 223. That is, after the funnel assembly 21 is removed from the floor support assembly, the spring 13, the top rod 14 and the fourth switch 223 are reset.

[0097] In some embodiments, the powder channel 7 is further provided with an air inlet 702 communicating with the powder channel 7.

[0098] The air inlet 702 is connected to an air pump. After the powder falls into the funnel assembly 21 through the powder channel 7, the air pump delivers air to the powder channel 7 through the air inlet 702 to purge the powder channel 7. A low-power air pump, such as a 12V air pump, can be used. The air pump cleans the powder in the powder channel 7, avoiding waste and preventing it from adhering to the channel 7. This reduces residual powder in the powder channel 7, which can affect the quality of the next coffee brew.

[0099] Combine Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 Taking coffee brewing as an example, the working principle of the brewing device is as follows: the funnel assembly 21 is placed into the lower cover 12 of the funnel bracket, the powder bowl 2101 contacts the push rod 14, and the push rod 14 triggers the fourth switch 223 of the upper cover 11 of the funnel bracket upward. The fourth switch 223 can send a corresponding detection signal to the controller of the coffee machine. The coffee machine can only start the coffee machine when it detects that the funnel assembly 21 is in place.

[0100] The coffee machine's reduction motor assembly starts rotating the first transmission gear 101, which drives the curved transmission teeth 401 of the inner transmission shaft. As the inner transmission shaft rotates, its external threads 402 engage with the internal threads 602 of the outer transmission shaft 6, driving the outer transmission shaft 6. The sliding groove 601 of the outer transmission shaft 6 rises along the positioning ribs 201 on the inner liner 2 until the outer periphery 603 of the outer transmission shaft 6 triggers the first switch 221 of the first switch 221 bracket 16, at which point the first transmission gear stops rotating. The second drive assembly activates and rotates the second transmission gear 18, which drives the rotating teeth 901 of the rotary door 9 until the teeth 901 trigger the third switch 10, aligning the valve opening 902 with the powder outlet 703 of the powder channel 7. The grinder assembly begins grinding the coffee beans, with the ground coffee flowing from the powder inlet 701 of the powder channel 7 to the powder outlet 703, and then falling into the powder bowl 2101 of the hopper assembly 21.

[0101] When the grinding is completed, the air pump blows away the residual powder in the powder channel 7 through the air inlet 702. After the air pump stops working, the second drive assembly drives the second transmission gear 18 to rotate. The second transmission gear 18 drives the rotating teeth 901 of the rotating door 9. The rotating lip 903 triggers the third switch 10, so that the valve opening 902 faces the exhaust hole 1101 of the funnel support cover 11, and the powder outlet 703 of the powder channel 7 is reclosed. The rotating door 9 is now restored to its normal position, that is, the position of blocking the powder outlet 703 of the powder channel 7. At this point, the rotating door 9 is reset.

[0102] When the third switch 10 detects that the rotating door 9 has been reset, the first drive assembly 1 rotates the first transmission gear 101, which in turn drives the rotating teeth 901 of the inner transmission shaft. The inner transmission shaft then descends the outer transmission shaft 6 until the outer periphery 603 of the outer transmission shaft 6 triggers the second switch 222 at the lower portion of the first switch 221 bracket 16, whereupon the inner transmission shaft 6 stops. The threaded coupling movement of the inner transmission shaft and the outer transmission shaft 6 forms a "powder hammer" that automatically compresses the powder in the powder bowl 2101. When the movable brewing head assembly flattens the powder in the powder bowl 2101, the heating boiler begins operating and outputs hot, cold, or room temperature water to the water inlet 801 of the brewing head cover 8, achieving automatic powder compaction and brewing.

[0103] The present application also provides a coffee machine, comprising the compressed powder brewing device as described in any of the above embodiments.

[0104] The above describes in detail multiple embodiments of the present invention, but the present invention is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of the present invention, and these variations and modifications should fall within the scope of protection required by the present invention.
