Description

Technical Field

[0001] This utility model relates to a coffee grinder, and more particularly to a coffee grinder structure used in coffee grinders. Background Technology

[0002] Coffee is a popular beverage in people's daily lives, and coffee grinders, also known as coffee grinders, provide coffee grounds to be ground into the desired powder and then discharged from the outlet. However, due to factors such as static electricity that may be generated during the operation of the grinder and the fineness of the coffee powder particles, static electricity can be generated on the surface of the coffee powder due to friction. This static electricity can easily cause static adsorption and flyaways, resulting in a large amount of flyaways sticking to the channel. Consequently, coffee powder is attracted to the inner wall of the outlet tube due to static electricity, and the formation of clumps often causes great trouble to the coffee extraction process.

[0003] Patent No. ZL202223499537.6, published on May 26, 2023, discloses a static electricity elimination structure for coffee powder used in a coffee grinder. The structure includes a grinding component and a static elimination component. The grinding component comprises a coffee grinder body with a discharge pipe connected to its surface. The static elimination component includes an ion generator and a sleeve. The ion generator is fixedly installed inside the coffee grinder body, and the sleeve is detachably and fixedly fitted to the bottom of the discharge pipe. A wire is connected to the top of the ion generator. When statically charged coffee powder is discharged from the discharge pipe of the coffee grinder body, the coffee powder enters the sleeve. The ion generator emits negative ions into the sleeve through the wire and electrode head. These negative ions actively neutralize the static electricity in the coffee powder, balancing its charge and preventing powder from adhering to the sleeve when it is finally discharged. While this solution largely eliminates static electricity, it does so by using an ion generator, which itself may have some adverse health effects on the human body during use. Utility Model Content

[0004] This invention addresses the problem of existing coffee grinders where static electricity generated by friction on the coffee grounds surface causes a large amount of fly-off coffee powder to stick to the channel, resulting in coffee grounds being attracted to the inner wall of the powder outlet tube due to static electricity. This leads to waste, reduced output, and significant disruption to the coffee extraction process due to residual powder accumulation and sticky lumps. The invention provides a coffee grinder structure that reduces static electricity accumulation during the coffee bean grinding process, thereby preventing waste, improving the purity of the coffee's flavor, and preventing bacterial growth.

A conductive metal base 31 is installed and connected on the grinder base 30. A conductive metal insert 60 (see...) is installed and connected on the metal support 50. Figure 2 , Figure 3The conductive metal base 30 and metal support 50 are used to provide support or lining for the receiving containers 20 and 20A, and both are used to increase the conductive metal area to reduce static electricity accumulation. The receiving containers are made of conductive metal.

Together with their corresponding connected powder outlet pipe 10, metal support 50 and the conductive metal area of ​​the receiving container 20, the overall effect is to increase the conductive metal area and release static electricity on the increased conductive metal area, thereby reducing the technical effect of static electricity accumulation. This effectively avoids the phenomenon of static electricity adsorption and flying powder during the coffee bean grinding process. Conductive connectors 41 are installed on the conductive wires or cables.

[0023] The conductive metal pressure plate 11 is made of stainless steel, copper, or chrome-plated material, and the conductive metal base 31 is made of stainless steel, copper, or chrome-plated material. The conductive metal insert 60 is made of copper, stainless steel, or chrome-plated material.

[0024] The receiving container 20 is a powder receiving cup that can directly contact the bottom of the cup with the top surface of the conductive metal base 31 (see...). Figure 1 , Figure 2 , Figure 3 As shown in the diagram, the conductive metal base 31 supports the bottom surface of the coffee bean receiving cup 20. The receiving cup is made of stainless steel or copper. The bottom of the receiving cup is in direct contact with the top surface of the conductive metal base 31, which effectively increases the conductive metal area and reduces static electricity accumulation. This effectively prevents static electricity from causing coffee bean powder to adhere and fly away during the grinding process.

[0025] The conductive metal structure of the powder outlet tube 10 and the metal support 50 is made of copper, stainless steel, or chrome-plated material. The conductive metal pressure plate is located at the upper end of the powder outlet tube where it is installed and connected to the powder outlet seat 03 of the grinder.

The internal threaded section of the first end of the columnar body is fastened to the metal support 50 by a bolt or screw 51.

[0028] Example 2:

[0029] Figure 4 In the illustrated embodiment, the receiving container is a handle-type coffee powder cup or a handle-type coffee extraction box 20A with a handheld handle 22A. The handle-type coffee powder cup or handle-type coffee extraction box 20A is made of stainless steel or copper. A metal bracket 51 is used to support and hold the handle-type coffee powder cup or handle-type coffee extraction box 20A. The handle-type coffee powder cup or handle-type coffee extraction box 20A has an outwardly protruding top edge 21A connected to it. The handle-type coffee powder cup or handle-type coffee extraction box 20A effectively supports the arc-shaped frame mounted on the metal bracket 50 (see figure) through its top edge 21A. Figure 2 The metal bracket 50 effectively supports and holds the handle-type powder cup or handle-type coffee extraction box 20A for receiving materials, while also effectively increasing the conductive metal area between the arc-shaped frame of the metal bracket 50 and the top edge 21A of the handle-type powder cup or handle-type coffee extraction box 20A, thereby reducing static electricity accumulation. Other aspects are the same as in Embodiment 1.

The negative terminal of the power supply is also the negative terminal of the power circuit in the control circuit board of the coffee grinder. Everything else is the same as in Embodiment 1 or Embodiment 2.

[0032] In use, the powder outlet pipe 10 is electrically connected to the conductive wire or cable 40 via the conductive metal pressure plate 11, effectively integrating the conductive metal area of ​​the powder outlet pipe 10 to increase the conductive metal area and reduce static electricity accumulation. Additionally, depending on the actual container shape used in the receiving containers 20 and 20A, the powder receiving cup 20 (see...) Figure 1 , Figure 2 , Figure 3 The powder container 20 is placed on the conductive metal base 31 (Example 1), effectively achieving a conductive connection between the bottom of the powder container 20 and the top surface of the conductive metal base 31. This integrates the conductive metal area of ​​the powder container 20 and the conductive metal base 31 with the conductive metal area of ​​the conductive metal base 31 and the powder dispensing tube 10, effectively increasing the conductive metal area and reducing static electricity accumulation. Alternatively, a portafilter powder container or portafilter coffee extraction cartridge 20A (see...) can be used. Figure 4 By supporting the outer edge 21A on the arc-shaped frame of the metal bracket 50 through its outward protruding top (Example 2), the conductive metal area of ​​the handle-type powder cup or handle-type coffee extraction box 20A can be integrated with the conductive metal base 31 and the powder outlet tube 10 to increase the conductive metal area and reduce static electricity accumulation.
