High-precision coffee grinders that can delay coffee bean supply

Abstract

A high-precision coffee grinder for delaying coffee bean supply includes: a grinding cassette; a grinding disc mounted at the bottom of the grinding cassette and positioned between the inlet and the lower opening of the grinding cassette. It further includes an input disc, the central post of which can pass through the central hole of the input disc. The input disc is fixed to the grinding cassette and located between the grinding disc and the inlet. The input disc is not fixed to the central post, so it does not rotate when the central post rotates. The input disc also forms at least one bean-passing hole. The purpose of the input disc is to impede the flow of coffee beans entering the grinding cassette. The grinder further includes a bean guide, the bean guide having a central post that can pass through the through hole of the bean guide. The bean guide is fixed to the grinding cassette and located between the grinding disc and the inlet. The function of the bean guide is to guide coffee beans from the bean-passing hole of the input disc. The central column of the bean guide has multiple guide rails formed around its periphery. Each guide rail is arranged from top to bottom along the periphery of the central column. The track of the guide rail forms a tortuous loop with the axis of the central column, which can enhance the path of the coffee beans falling from above to the grinding disc below.

Claims

1. A high-precision coffee grinder that can delay the supply of coffee beans, comprising: a grinding box (10), the upper end of which has an inlet (11) for receiving externally input coffee beans; the lower end of which has a lower opening (12); a grinding disc (20), installed at the bottom of the grinding box (10) and located between the inlet (11) and the lower opening (12) of the grinding box (10), the grinding disc (20) being a rotatable hollow annular structure; wherein a central column (22) extends from the upper end of the grinding disc (20); the grinding disc (20) also has a blade disc (25) for grinding coffee beans entering above the grinding disc (20); and further comprising an input disc (30), the input disc (30) having a central hole (32), the grinding disc... The central post (22) of (20) can pass through the central hole (32) of the input disk (30). The input disk (30) is fixed on the grinding box (10) and located between the grinding disk (20) and the input port (11). The input disk (30) is not fixed on the central post (22), so when the central post (22) rotates, the input disk (30) will not rotate with it. The input disk (30) also forms at least one bean piercing hole (35), the size of which allows at least one coffee bean to pass through. The purpose of the input disk (30) is to create a flow obstruction effect on the coffee beans entering the grinding box (10), and then slowly flow through the bean piercing hole (35) and roll down into the gap between the grinding disk (20) and the cutting disk (25) for grinding.

2. The high-precision coffee grinder that can delay the supply of coffee beans as described in claim 1 further includes a bean guide (40), which includes a central post (45) with a through hole (42) formed in the center of the central post (45). The central post (22) of the grinding disc (20) can pass through the through hole (42) of the bean guide (40), and the bean guide (40) is fixed on the grinding box (10) and located between the grinding disc (20) and the input port (11), so that the bean guide (40) is positioned between the grinding disc (20) and the input plate (30), and the input plate (30) does not rotate with the grinding disc (20); wherein the function of the bean guide (40) is to guide the coffee beans from the input port (11) into the grinding box.

3. The high-precision coffee grinder that can delay the supply of coffee beans as described in claim 2, wherein the outer periphery of the central column (45) of the bean guide (40) forms a plurality of guide rails (48), each guide rail (48) being arranged from top to bottom along the outer periphery of the central column (45), wherein the track of the guide rail (48) forms a tortuous ring with the axial direction of the central column (45), thereby strengthening the path of the coffee beans falling from above to the grinding disc (20) below, that is, its function is to lengthen the entire movement path of the coffee beans in the grinding box (10); so that the grinding box (10) has sufficient time to grind the coffee beans, so that the coffee beans can be ground more evenly.

4. The high-precision coffee grinder that can delay the supply of coffee beans as described in claim 1 further includes a drive mechanism (60) connected to the central column (22) of the grinding disc (20) for driving the grinding disc (20) to rotate. When the grinding disc (20) rotates, the coffee beans that fall into the grinding disc (20) from the input port (11) are ground into powder and output downward from below the gap.

5. The high-precision coffee grinder that can delay the supply of coffee beans as described in claim 4, wherein the drive mechanism (60) is a motor and the motor shaft (61) of the motor is directly connected to the central column (22) of the grinding disc (20).

6. The high-precision coffee grinder that can delay the supply of coffee beans as described in claim 4, wherein the drive mechanism (60) is a handle (26) extending outward from the central post (22) of the grinding disc (20); so the user can drive the central post (22) of the grinding disc (20) to rotate by turning the handle (26), so that the grinding disc (20) can grind the coffee beans on its disc surface.

7. The high-precision coffee grinder that can delay the supply of coffee beans as described in claim 1, wherein the grinding disc (20) also has a blade disc (25) for grinding coffee beans entering above the grinding disc (20).

8. The high-precision coffee grinder that can delay the supply of coffee beans as described in claim 1, wherein the input plate (30) also forms 3 bean-piercing holes (35) spaced approximately 120 degrees apart.
