[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figures 1-5As shown, the semi-automatic coffee machine with a grinding device provided in this embodiment includes a casing 1. A mounting frame 2 is fixedly installed inside the casing 1. A drive motor 3 is fixedly installed on the mounting frame 2. A first rotating shaft 4 is fixedly installed at the output end of the drive motor 3. A first pulley 5 is fixedly installed at the end of the first rotating shaft 4 away from the drive motor 3. A second pulley 6 is provided on one side of the first pulley 5. The second pulley 6 is connected to the first pulley 5 via a belt 7. A second rotating shaft 8 is fixedly connected to the second pulley 6. The second rotating shaft 8 is rotatably mounted on the mounting frame 2, and a burr 9 is fixedly installed at the end of the second rotating shaft 8 away from the second pulley 6. A burr 9 is provided on the outer side of the burr 9. The machine has a grinding chamber 10, a bean storage chamber 11 above the grinding chamber 10, and a discharge pipe 12 fixedly installed on one side of the grinding chamber 10. A baffle 13 is rotatably connected inside the discharge pipe 12. Coffee beans are poured into the bean storage chamber 11 and then flow into the grinding chamber 10. The drive motor 3 is turned on to drive the first rotating shaft 4 to rotate, which drives the first pulley 5 to rotate. The belt 7 drives the second pulley 6 to rotate, and the second rotating shaft 8 drives the blade 9 to rotate, grinding the coffee beans inside the grinding chamber 10. The ground coffee beans then flow out through the discharge pipe 12, thus realizing the grinding process of coffee beans and greatly improving the output efficiency of the coffee machine.

[0026] Furthermore, such as Figures 1-5 As shown, a powder receiving bracket 14 is fixedly installed on one side of the chassis 1. A touch switch 15 is provided on one side of the powder receiving bracket 14. The touch switch 15 is fixedly installed on the chassis 1. The powder bowl is placed on the powder receiving bracket 14. The powder receiving bracket 14 has a powder pressing device, which is not shown in the figure. When the touch switch 15 is touched, the powder bowl receives the powder.

[0027] Furthermore, such as Figures 1-5 As shown, a bean hopper mounting bracket 16 is fixedly installed at the upper end of the grinding chamber 10. The side of the bean hopper mounting bracket 16 away from the grinding chamber 10 is fixedly connected to the bean storage chamber 11. A bean hopper pusher 17 is slidably connected inside the bean hopper mounting bracket 16. When coffee beans are poured into the bean storage chamber 11, the bean hopper pusher 17 is pulled out and slid inside the bean hopper mounting bracket 16, thereby controlling the flow of coffee beans into the grinding chamber 10.

[0028] Furthermore, such as Figures 1-5 As shown, a boiler 18 is fixedly installed inside the chassis 1 by a bracket. Two delivery pipes 19 are fixedly installed on the boiler 18. The other end of the delivery pipe 19 passes through the chassis 1 and is fixedly installed with a brewing head 20. Hot water inside the boiler 18 flows into the interior of the two brewing heads 20 through the delivery pipes 19, and then the hot water is evenly penetrated into the coffee powder layer through the two brewing heads 20, thereby achieving uniform extraction.

[0029] Furthermore, such as Figures 1-5As shown, a multi-port connector 21 is fixedly installed on the boiler 18. One end of the multi-port connector 21 is fixedly connected to a steam switch 22 via a hose. A steam pipe 23 is fixedly connected to the steam switch 22. When the steam switch 22 is turned on, steam flows into the steam pipe 23, and the steam can then be used to heat the beverage.

[0030] Furthermore, such as Figures 1-5 As shown, several evenly distributed control buttons 24 are provided above the two brewing heads 20. An operation screen 25 is provided on one side of the control buttons 24. The control buttons 24 and the operation screen 25 are fixedly installed on one side of the machine box 1. The opening and closing of the brewing heads 20 can be controlled by the control buttons 24, and the operation of the coffee machine can be controlled by the operation screen 25.

[0031] Furthermore, such as Figures 1-5 As shown, a filter holder 26 is provided below the brewing head 20, and a wastewater tray 27 is provided below the filter holder 26. Both the filter holder 26 and the wastewater tray 27 are fixedly installed on the machine casing 1, and a drain hole 28 is provided in the center of the wastewater tray 27. Two pressure gauges 29 are fixedly installed on one side of the machine casing 1. When brewing coffee, the overflowing coffee flows into the wastewater tray 27 through the filter holder 26 and is then discharged through the drain hole 28 to prevent contamination of the coffee machine and affect its normal use.

[0032] like Figures 1-5 As shown, the principle of the semi-automatic coffee machine with a coffee grinding device provided in this embodiment is as follows:

[0033] Coffee beans are poured into the bean storage hopper 11 and then flow into the grinding chamber 10. The drive motor 3 is turned on, which drives the first rotating shaft 4 to rotate, which in turn drives the first pulley 5 to rotate. The belt 7 drives the second pulley 6 to rotate, and the second rotating shaft 8 drives the burr 9 to rotate, grinding the coffee beans inside the grinding chamber 10. The ground coffee beans then flow out through the discharge pipe 12, thus realizing the grinding process of coffee beans. The coffee bowl is placed on the coffee receiving bracket 14, and the touch switch 15 is activated. The coffee bowl receives the coffee powder, and the hot water inside the boiler 18 flows into the two brewing heads 20 through the delivery pipe 19. The hot water is then evenly penetrated into the coffee powder layer through the two brewing heads 20, which can achieve uniform extraction and greatly improve the output efficiency of the coffee machine.
