[0014] This espresso extraction and impurity removal equipment involves placing coffee beans into the grinding jar. An electric push rod moves a slider and lifting plate, while a drive mechanism inside the lifting plate rotates a rotating disc, aligning the triangular grinding head, semi-circular grinding head, and compaction plate with the three grinding jars on the upper part of the middle plate. The electric push rod lowers the lifting plate, allowing the triangular and semi-circular grinding heads to enter the grinding jars for grinding. After the triangular and semi-circular grinding heads have separated and ground the coffee beans in each of the three jars, the lifting rod lowers the compaction plate, which then compacts the coffee powder in each of the three jars. Finally, a suitable amount of boiling water is poured into the grinding jar, and the lid is placed on top. After a period of settling, a drive shaft rotates the sealing plate, allowing the coffee from the grinding jars to enter the middle plate. A pump then draws the coffee from the middle plate into the filter tube, and the filtered coffee is delivered to the coffee cup. In this extraction and impurity removal process, manual operation is only required for the less challenging parts; grinding and filtering are all completed mechanically, resulting in higher efficiency.

[0023] like Figures 1 to 5 As shown, the espresso extraction and impurity removal device in this embodiment includes a support frame 1, as shown in the figure. Figure 1As shown, the inner wall of the support frame 1 has a semi-circular arc, mainly for support. A groove 2 is provided at the upper front end of the support frame 1. An electric push rod 6 is installed at the bottom of the groove 2, and a slider 3 is installed at the upper end of the electric push rod 6. The electric push rod 6 is connected to an external power source, which can drive the slider 3 to move up and down within the groove 2. A lifting plate 4 is installed at the front end of the slider 3, and the slider 3 is fixedly connected to the lifting plate 4. When the slider 3 moves up and down, it will drive the lifting plate 4 to move up and down synchronously. It should be noted that the side wall of the lifting plate 4 needs to be slidably connected to the inner wall of the support frame 1 through a guide rail. The guide rail limits and guides the movement trajectory, which is a conventional existing technology. A triangular grinding head 17, a semi-circular grinding head 16, and a compaction plate 18 are sequentially installed in a triangular equidistant array at the lower end of the lifting plate 4. The semi-circular grinding head 16 and the triangular grinding head 17 can grind the grinding jar. The coffee powder inside the 9 is thoroughly ground, and the compaction plate 18 can compact the ground coffee powder. A middle plate 5 is installed at the front middle of the support frame 1. Three grinding jars 9 are installed in a triangular equidistant array at the upper end of the middle plate 5. The bottom of the grinding jars 9 is connected to the inside of the middle plate 5 through a sealing plate 22. After grinding, an appropriate amount of boiling water is added into the grinding jars 9 to brew the coffee powder and let it stand for a period of time. A base 8 is installed at the lower front of the support frame 1. A coffee cup 21 is set at the upper end of the base 8. A pump body 19 is installed at the lower end of the middle plate 5. A filter tube 20 is installed at the lower end of the pump body 19. The filter tube 20 is located at the upper end of the coffee cup 21. The coffee liquid enters the interior of the middle plate 5 and is drawn out by the pump body 19 and enters the interior of the filter tube 20 for filtration. The filtered coffee liquid enters the interior of the coffee cup 21, completing the extraction and impurity removal steps.

[0024] Specifically, a drive shaft 23 is rotatably connected to the top of the inner layer plate 5. Multiple sealing plates 22 are installed in an equidistant array on the side wall of the drive shaft 23. A drive device is installed at the center of the upper end of the middle layer plate 5. The drive device can drive the drive shaft 23 to rotate, and the drive shaft 23 drives the multiple sealing plates 22 to rotate.

[0025] Furthermore, an active turntable 14 is installed at the lower end of the lifting plate 4. Two protective housings 15 and a lifting rod 24 are installed in a triangular equidistant array at the lower end of the active turntable 14. A drive device is installed inside the protective housing 15. The output ends of multiple drive devices are connected to the semi-circular grinding head 16 and the triangular grinding head 17 respectively. The lower end of the lifting rod 24 is connected to the compaction plate 18. It should be noted that the semi-circular grinding head 16 and the triangular grinding head 17 are longer than the compaction plate 18. When the lifting plate 4 descends, the semi-circular grinding head 16 and the triangular grinding head 17 will first connect with the bottom of the grinding tank 9, while the compaction plate 18 needs to be driven by the lifting rod 24 to contact the bottom of the grinding tank 9.

[0026] Furthermore, a scale 12 is installed on the surface of the grinding jar 9, through which the material height inside the grinding jar 9 can be observed. The grinding jar 9 is a transparent jar.

[0027] Furthermore, the front end of the support frame 1 is rotatably connected to multiple opening and closing doors 7, such as... Figure 1 As shown, the middle layer plate 5 has two opening and closing doors 7 at both the top and bottom ends for sealing the equipment. The upper end of the filter tank is equipped with a cover 13. After water is added, the grinding tank 9 needs to be sealed by the cover 13.

[0028] Furthermore, the filter tube 20 includes an upper interface 2001, an installation tube 2002, a liquid outlet 2003, and a filter screen 2004. The upper interface 2001 is installed at the lower end of the pump body 19, the installation tube 2002 is installed at the lower end of the upper interface 2001, the liquid outlet 2003 is installed at the lower end of the installation tube 2002, and multiple filter screens 2004 are installed in a longitudinally equidistant array inside the installation tube 2002. The upper interface 2001, the installation tube 2002, and the liquid outlet 2003 are connected separately and can be disassembled and installed. The multiple filter screens 2004 of the installation tube 2002 can filter the coffee liquid inside. An air vent 10 is opened at the upper end of the middle plate 5. A limit rod 11 is installed inside the air vent 10. The air vent 10 can exhaust the coffee liquid inside the middle plate 5, thereby cooling it down.

[0029] The method of use in this embodiment is as follows: Place the coffee beans to be ground into the grinding jar 9. The electric push rod 6 moves the slider 3 and the lifting plate 4. The drive device inside the lifting plate 4 rotates the active turntable 14, aligning the triangular grinding head 17, the semi-circular grinding head 16, and the compaction plate 18 with the three grinding jars 9 at the upper end of the middle layer plate 5. The electric push rod 6 lowers the lifting plate 4, allowing the triangular grinding head 17 and the semi-circular grinding head 16 to enter the grinding jar 9 for grinding. The triangular grinding head 17 and the semi-circular grinding head 16 grind the coffee beans. After the coffee beans inside the three grinding jars 9 are separated and ground, the pressing plate 18 is lowered by the lifting rod 24. The pressing plate 18 compacts the coffee powder inside the three grinding jars 9 in turn. Finally, an appropriate amount of boiling water is poured into the grinding jars 9 and the lid 13 is placed on the top of the grinding jars 9. After standing for a period of time, the sealing plate 22 is rotated by the drive shaft 23, so that the coffee inside the grinding jars 9 enters the middle plate 5. The pump body 19 draws the coffee inside the middle plate 5 into the filter tube 20, and the filtered coffee is sent into the coffee cup 21.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
