[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The coffee brewing assembly provided in the embodiment of the present invention can be used not only for grinding coffee beans but also for other bean-shaped products to be ground and brewed. The following description will be made using grinding and brewing coffee as an example.

[0039] like Figures 1 to 18As shown, on the one hand, the present invention proposes a coffee brewing assembly, which includes: a bracket 21, having a base, and the base is provided with a powder outlet 211; a shower assembly 3, arranged below the powder outlet 211, for connecting to the water inlet joint 14; a powder door 29, arranged below the powder outlet 211; a driving assembly, used to drive the powder door 29 to open or close the powder outlet 211 and simultaneously drive the shower assembly 3 to rotate, after the powder door 29 is opened, the driving assembly stops driving the shower assembly 3 to rotate; after the powder door 29 is closed, the driving assembly can continue to drive the shower assembly 3 to rotate to spray and extract coffee.

[0040] like Figure 6 As shown, the base of the bracket 21 is provided with a powder outlet 211, and the powder door 29 is provided below the powder outlet 211; the driving component drives the powder door 29 to slide back and forth between the open position and the closed position, and the powder door slides to the open position, and the powder door 29 opens the powder outlet 211, and the shower assembly 3 can rotate with the sliding of the powder door to one side of the powder outlet 211, or the shower assembly 3 can be slightly shorter and avoid the powder outlet 211 when rotating, and hot water scatters from the spray port and can fall on the coffee powder, as shown in FIG. Figure 3 As shown; the powder door slides to the closed position, the powder door 29 closes the powder outlet 211, the shower assembly 3 can rotate as the powder door slides, and after the powder door is closed, it can still continue to rotate clockwise or counterclockwise below the powder door 29.

[0041] The powder door 29 has an open position and a closed position. In the open position, the powder door 29 opens the powder outlet 211. After the shower assembly 3 rotates to one side of the powder outlet 211, the shower assembly does not rotate regardless of whether the driving assembly continues to drive; in the closed position, the driving assembly can continue to drive the shower assembly 3 to rotate clockwise or counterclockwise below the powder door 29. That is, after the powder door 29 is closed, the driving assembly can continue to drive the shower assembly 3 to rotate and spray hot water onto the filter to fully extract the coffee spilled in the filter.

[0042] The specific usage process is as follows: before grinding, the driving assembly drives the powder door 29 to open, and at the same time drives the shower assembly 3 to rotate, the powder door is in the open position, the powder outlet 211 is in the open state, the shower assembly can be moved to the side of the powder outlet 211 or the shower assembly is short enough, so that the shower assembly can move to any position to avoid the powder outlet, the bean grinding assembly 11 works, and the coffee beans are ground into coffee powder and fall from the powder outlet 211 and fall into the filter below; when the grinding is completed, the driving assembly drives the powder door 29 to close, and at the same time, drives the shower assembly 3 to rotate. After the powder door 29 is closed, the driving assembly can continue to drive the shower assembly 3 to rotate to allow hot water to rotate and spray to extract the coffee, so that the coffee molecules are more fully extracted and the coffee is more fragrant.

[0043] In order to achieve simultaneous movement of the powder door 29 and the shower assembly 3, the drive assembly can adopt a variety of structures, as long as it can achieve the movement of the powder door between the open position and the closed position, and the shower assembly can rotate under the powder door.

[0044] As an example of a driving component, the driving component drives the powder door 29 to slide relative to the powder outlet 211; the base of the bracket 21 is provided with a first circular hole 213 and a second circular hole 214, such as Figure 6 As shown; the driving assembly is arranged on the upper surface of the base of the bracket 21, and the driving assembly includes: a synchronous motor 16, a driven gear 15 and a driving gear assembly 2; the output shaft of the synchronous motor 16 is connected to the driving gear assembly 2, and the driving gear assembly 2 is engaged with the driven gear 15; the driving gear assembly 2 can be limitatively connected or released from the limit connection to one end of the rocker arm assembly through the first circular hole 213, and the other end of the rocker arm assembly is hinged to the powder door 29; the driven gear 15 is detachably connected to the shower assembly 3 through the second circular hole 214.

More specifically, the output shaft 161 of the synchronous motor 16 is inserted into the first mounting hole 171, and the mounting port 162 of the synchronous motor 16 is fixedly connected to the second mounting column 216 of the bracket 21; wherein, one second mounting column 216 is provided on the accommodating groove, and another second mounting column 216 is provided at the bottom of the bracket 21.

[0046] like Figure 3 As shown, the driving gear assembly 2 drives the rocker arm assembly to rotate clockwise, the powder door 29 moves to the right, and the powder outlet 211 is opened. The driven gear 15 drives the shower assembly to rotate counterclockwise and can be rotated to the left side of the powder outlet 211; the driving gear assembly 2 drives the rocker arm assembly to rotate counterclockwise, the powder door 29 moves to the left, and the powder outlet 211 is closed. The driven gear 15 drives the shower assembly to rotate clockwise and rotate to the bottom or right side of the powder outlet 211. The rotation distance can be set according to actual conditions, or the shower assembly is short enough and can be rotated to any position without blocking the powder outlet 211.

[0047] like Figure 10As shown, as an example of a driving gear assembly, the driving gear assembly 2 includes: a driving gear 17 and a powder door pin assembly, the driving gear 17 is circumferentially provided with a first gear 172, a first mounting hole 171 is provided in the central area of one end of the driving gear 17, and a second mounting hole is provided at the other end, and the diameter of the second mounting hole is larger than the first mounting hole 171; the rocker arm assembly includes a rocker arm 27 and a fixing member 20; the output shaft of the synchronous motor 16 is inserted into the first mounting hole 171, and the powder door pin assembly and the fixing member 20 that can be limitably connected or release-connected to the powder door pin group are provided in the second mounting hole, and the fixing member 20 is connected to one end of the rocker arm 27; the powder door pin assembly is limit-connected to the fixing member 20, and the driving gear 17 can drive the rocker arm 27 to rotate together, and the powder door pin assembly is release-connected to the fixing member 20, only the driving gear 17 rotates, and the rocker arm 27 does not rotate.

[0048] The first gear 172 is engaged with the driven gear. Figure 17 As shown, the rocker arm 27 is provided with a third mounting hole 271 and a waist hole 272; specifically, a mounting plate is provided at one end of the rocker arm 27, and a third mounting hole 271 is provided in the central area of the mounting plate; Figure 15 As shown, a snap-on portion 202 is provided in the center of one side of the fixing member 20. This snap-on portion 202 engages with the third mounting hole 271 of the rocker arm and is bolted together through the central hole. A fixing plate 28 acts as a gasket and is bolted to the bottom of the mounting plate. The hole 281 of the fixing plate corresponds to the third mounting hole 271 of the mounting plate. A groove is provided on the edge of the fixing member 20 to engage with the powder door pin assembly.

[0049] like Figure 16 and Figure 17 As shown, a waist hole 272 is provided at the other end of the rocker arm 27, and the powder door 29 is fixedly connected to the pin 26 through a connecting hole 292 provided at one end thereof; the pin 26 passes through the waist hole 272 and can move in the waist hole 272, and the base is provided with a receiving groove facing the upper surface to avoid accommodating the pin 26.

[0050] like Figure 17 As shown in Figure (b), the pin 26 is provided with a second connecting column 261; Figure 18 As shown, the powder door 29 includes a door body 291 and a connection hole 292 provided on one side of the door body near the edge; Figure 16As shown, the rocker arm 27 is hingedly connected to the powder door 29. More specifically, the second connecting column 261 of the pin 26 passes through the waist hole 272 of the rocker arm 27 and is tightly connected to the hole 292 of the powder door 29, so that the pin 26 is fixedly connected to the powder door 29. The waist hole 272 is large enough to allow the pin 26 to move within the waist hole 272. The powder door 29, pin 26, and rocker arm 27 constitute the powder door assembly 4, which is mounted on the driving gear assembly 2. More specifically, the third mounting hole 271 of the rocker arm 27 is ensured to be inserted into the clamping portion 202 of the fixing member 20 and fixed by bolts.

[0051] like Figure 1 and Figure 14 As shown in (b), as an example of a powder door pin assembly, the powder door pin assembly includes a powder door pin 19, a first elastic member 18 and a connecting member, as shown in FIG. Figure 10 As shown in (d), the edge of the second mounting hole is provided with two slots 174 with side wall openings, and the two slots 174 are respectively inserted with the powder door pins 19. Figure 10 As shown in (c); each of the powder door pins 19 is sleeved with a first elastic member 18 at one end 191 close to the bottom of the second mounting hole, and the two ends of the first elastic member 18 respectively abut the bottom wall of the second mounting hole and the connecting member; the fixing member 20 is provided with two guide grooves 201, and the ends of the two powder door pins 19 facing away from the bottom of the second mounting hole are respectively provided with guide portions 192 facing opposite directions, and the guide portions 192 cooperate with the guide grooves 201 of the fixing member 20, so that the powder door pin 19 can move vertically in the slot 174.

[0052] like Figure 10 As shown, two opposite slots 174 are provided near the edge of the second mounting hole of the driving gear 17, and the two slots are used to set the powder door pin 19. A fixing member 20 is provided between the driving gear 17 and the rocker arm. Figure 15 As shown, the edge of the fixing member is provided with two opposing guide slots 201. These slots 201 serve as through-holes for the guide portion 192, which mates with the guide portion of the powder door pin 19. The guide portion 192 of the powder door pin 19 is an inclined surface. A third mounting hole 271 is provided in the central area of the rocker arm mounting plate, which mates with the fixing member's engaging portion. The edge area is provided with through-holes that mate with the guide slots on the edge of the fixing member and are used to accommodate the guide portion of the powder door pin 19. The other two holes are screw holes.

[0053] like Figure 10As shown, the driving gear consists of a column and a first gear 172 surrounding the column. The first gear 172 is located near one end of the column, and the portion of the column that extends outward forms a first mounting post 173, which is inserted into the first circular hole 213 of the bracket base. An annular groove is formed between the first mounting post 173 and the slot 174, which can be used to loosely engage the annular protrusion on the edge of the fixing member 20. In this way, the fixing member 20 can be confined within the second mounting hole and can also be movably connected to the driving gear. The first elastic member 18 is a compression spring. The compression spring is installed on the upper end 191 of the powder door pin 19 and is inserted into the slot 174 of the second mounting hole of the driving gear 17 to ensure smooth up and down movement. The fixing member 20 is arranged between the guide portion 192 of the powder door pin 19 and the driving gear 17, ensuring that the guide portion 192 is inserted into and disengaged from the guide groove 201 of the fixing member 20 to allow the powder door pin 19 to move smoothly; the driving gear assembly 2 is arranged in the first circular hole 213 of the bracket 21, more specifically, ensuring that the first mounting post 173 of the driving gear 17 is inserted into the first circular hole 213 of the bracket 21, and ensuring that the first gear 172 of the driving gear 17 is engaged with the tooth position 154 of the driven gear 15.

[0054] The working process of the driving gear assembly is as follows: the synchronous motor 16 drives the driving gear to drive the powder door to rotate in the direction of closing the powder outlet 211, and the driven gear drives the shower assembly to rotate. The powder door pin 19 abuts against the guide groove 201 of the fixing member 20 under the action of the first elastic member 18. When the powder door 29 closes the powder outlet 211, the pin 26 moves to one end of the receiving groove, and the synchronous motor continues to drive the driving gear to rotate. The pin 26 is blocked and does not move, causing the rocker arm and the fixing member to remain stationary, which makes the powder door pin 19 move upward along the guide groove 201 of the fixing member 20 at its guide portion 192, compressing the first elastic member 18 until the powder door 29 closes the powder outlet 211. The door push pin 19 disengages from the guide groove 201, and the driving gear rotates. At this time, the driven gear drives the shower assembly to continue rotating as the driving gear rotates, while the powder door 29 does not move; when the synchronous motor drives the driving gear 17 to drive the powder door 29 to rotate in the opposite direction to open the powder outlet 211, similarly, the driven gear drives the shower assembly to rotate, and the pin 26 moves to the other end of the accommodating groove. Even if the synchronous motor 16 continues to drive the driving gear to rotate, the cross-section of the powder door push pin 19 without a guide portion abuts against the guide groove of the fixing member 20, and no relative sliding occurs, and the elastic member cannot be compressed to disengage from the guide groove, so that the driven gear will not continue to rotate.

[0055] The synchronous motor drives the active gear to touch the micro switch to achieve forward and reverse brewing of coffee, and the powder door is linked to move back and forth in a straight line to open and close, which facilitates smooth powder falling. At the same time, the active gear and the driven gear are engaged with the straight teeth, driving the spray shower to rotate and spray hot water to extract the coffee, so that the coffee powder can be fully extracted and the coffee liquid has a more mellow flavor.

[0056] like Figure 8As shown, as an example of a driven gear, the driven gear 15 includes a second gear 154, the first surface of the second gear 154 is provided with a first water inlet end, and the second surface of the second gear 154 is provided with a second water outlet end 152; the first water inlet end and the second water outlet end 152 are respectively provided with a first water inlet 151 and a second water outlet that are interconnected; the first water inlet end is used to detachably connect to the water inlet connector 14, and the second water outlet end 152 is detachably connected to the shower assembly 3.

[0057] like Figure 9 As shown, the water inlet connector 14 comprises a connector body and a connecting pipe.
