Description

Technical Field

[0001] This invention relates to a coffee grinder capable of separating coarse and fine coffee beans. Background Technology

[0002] When grinding coffee beans, the coarseness of the powder depends on the brewing method. Generally speaking, the shorter the brewing time, the finer the grind should be; the longer the brewing time, the coarser the grind should be. In practical terms, espresso machines require very short brewing times, so the grind is extremely fine, almost like flour. Siphon brewing takes about a minute, so the grind is medium-coarse. American drip coffee has a longer brewing time, so the grind is the coarsest, with individual grains resembling seashells on a beach. Properly ground coffee is crucial for making a good cup of coffee because the extraction of water-soluble substances in the coffee grounds has an ideal timeframe. If the grind is too fine and the brewing is too long, over-extraction can occur, resulting in a very strong, bitter coffee that lacks aroma. Conversely, if the grind is too coarse and the brewing is too fast, under-extraction can occur, resulting in a weak and tasteless coffee because the water-soluble substances in the grounds haven't had enough time to dissolve.

[0003] Currently, most coffee grinders on the market grind coffee into powders of varying coarseness by adjusting their settings to meet the needs of making different types of coffee (such as espresso, Americano, pour-over, French, etc.). For example, the particle size range required for pour-over coffee is approximately 400 to 600 micrometers. However, coffee beans are quite brittle after roasting, and no matter how the grinder is adjusted, there will generally be particles that are much larger than this range mixed in, making it difficult to obtain coffee powder with uniform particle size.

[0004] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Summary of the Invention

[0005] This invention overcomes the shortcomings of the above-mentioned technologies and provides a coffee grinder that can separate coarse and fine particles. This coffee grinder can collect powder particles of uniform size within a reasonable range, making the coffee powder uniform in size and making coffee extraction more convenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coffee grinder capable of separating coarse and fine coffee powder includes: a base, a drive motor and a control main board disposed within the base, the drive motor and the control main board being electrically connected, a powder storage device driven by the drive motor disposed on the base, the powder storage device being used to hold coffee powder, pepper powder or other powders, a powder outlet disposed on the powder storage device, and a powder receiving tray disposed outside the powder storage device.

[0008] Preferably, the powder receiving tray is provided with a cover as described above, a ventilation pipe is provided at the upper end of the cover, a fan is provided inside the ventilation pipe, a powder collection box is provided above the ventilation pipe, an air outlet is provided at the upper part of the powder collection box, and an air pump is provided on the powder collection box. The air pump is connected to the powder receiving tray through the air outlet and the ventilation pipe.

[0009] Preferably, the powder receiving tray is provided with multiple partition plates as described above, and the multiple partition plates divide the powder receiving tray into multiple powder storage tanks.

[0010] Preferably, as described above, both the separator and the powder storage tank are annular.

[0011] Preferably, a plurality of baffles are provided on the inner sidewall of the powder collection box as described above, and the plurality of baffles and the lower inner sidewall of the powder collection box form a plurality of powder collection boxes.

[0012] Preferably, as described above, the powder storage device is funnel-shaped.

[0013] Preferably, the powder storage device, which is funnel-shaped as described above, has holes.

[0014] Preferably, a speed control knob is provided on the base as described above, and the speed control knob is electrically connected to the control main board.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention provides a coffee grinder capable of separating coarse and fine particles. This coffee grinder can collect powder particles of uniform size within a reasonable range, making the coffee powder uniform in size and making coffee extraction more convenient.

[0017] 2. This invention provides a coffee grinder capable of separating coarse and fine coffee powder. The base includes a control board, a drive motor, a knob, and a powder storage container. Coffee powder is added to the powder storage container. Different speeds are selected using the knob, and the control board controls the drive motor to rotate the powder storage container at different speeds and for different durations. Due to the different particle sizes, the centrifugal forces experienced by the powder are also different. Particles of different sizes are thrown out of the powder storage container (preferably funnel-shaped, with or without holes) by different distances under the action of centrifugal force, thus being ejected to different areas A, B, and C of the powder receiving tray, thereby achieving separation of coarse and fine coffee powder. An air pump is attached to the top, which draws in air to suck away the even finer powder. When passing through the fixed fan blades on the top cover, the powder is forced to rotate and is decelerated at the outer wall ribs, thus being collected. Attached Figure Description

[0022] The following examples further illustrate the features of the present invention and other related features in detail, so as to facilitate understanding by those skilled in the art.

[0023] In this embodiment, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0024] like Figures 1 to 4 As shown, a coffee grinder capable of separating coarse and fine coffee powder includes: a base 1, a drive motor 11 and a control main board 12 disposed within the base 1, the drive motor 11 and the control main board 12 being electrically connected, a powder storage device 2 driven by the drive motor 11 disposed on the base 1, the powder storage device 2 being used to hold coffee powder, pepper powder or other powders, a powder outlet disposed on the powder storage device 2, and a powder receiving tray 3 disposed outside the powder storage device 2. This invention provides a coffee grinder capable of separating coarse and fine coffee powder, which can collect powder particles of uniform size within a reasonable range, making the coffee powder uniform in size and making coffee extraction more convenient.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, in this embodiment, a cover 4 is provided on the powder receiving tray 3, a ventilation pipe 41 is provided at the upper end of the cover 4, a fan 5 is provided inside the ventilation pipe 41, a powder collection box 6 is provided above the ventilation pipe 41, an air outlet 61 is provided at the upper part of the powder collection box 6, and an air pump 7 is provided on the powder collection box 6. The air pump 7 is connected to the powder receiving tray 3 through the air outlet 61 and the ventilation pipe 41. This invention provides a coffee grinder that can achieve coarse and fine coffee separation. The base has a control board, a drive motor, a knob, and a powder storage container. Coffee powder is added to the powder storage container, and the grinder is selected by turning the knob. Selecting different gears controls the mainboard to drive the motor at different speeds and for different durations, causing the powder storage container to rotate. Due to the different particle sizes, the centrifugal force experienced by the powder is also different. Particles of different sizes are thrown out of the powder storage container (preferably funnel-shaped, with or without holes) by different distances under the action of centrifugal force, and are thus thrown into different areas A, B, and C of the powder receiving tray, thereby achieving separation of fine and coarse powder. An air pump is attached to the top, which draws in air to suck away the even finer powder. When passing through the fixed fan blades on the top cover, the powder is forced to rotate and is decelerated at the outer wall ribs, thus being collected.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, the powder receiving tray 3 is provided with multiple partition plates 31, which divide the powder receiving tray 3 into multiple powder storage tanks 32. For example, the powder storage tanks 32 can be divided into different areas A, B, and C by the partition plates 31. These areas are at different distances from the central powder storage device, and the coarseness of the coffee powder falling into the different areas A, B, and C of the powder storage tanks 32 is different, thereby achieving coarse-fine separation.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, both the separator 31 and the powder storage tank 32 are annular. The base is equipped with a control board, a drive motor, a knob, and a powder storage device. Coffee powder is added to the powder storage device. Different gears are selected by the knob. The control board controls the drive motor to rotate the powder storage device at different speeds and for different durations. Due to the different particle sizes, the centrifugal forces experienced by the powder are also different. Particles of different sizes are thrown out of the powder storage device (preferably funnel-shaped, with or without holes) by different distances under the action of centrifugal force, and are thus thrown into different areas of the powder receiving trays A, B, and C, thereby achieving powder separation. An air pump is attached to the top. The air pump sucks away the finer powder, which is forced to rotate when passing through the fixed fan blades of the top cover. It is obstructed and decelerated at the outer wall ribs, and is thus collected.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, a plurality of baffles 62 are provided on the inner side wall of the powder collection box 6. The plurality of baffles 62 and the lower inner side wall of the powder collection box 6 form a plurality of powder collection boxes 63. The powder collection boxes 63 collect very small coffee powder particles, which is convenient for brewing espresso.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, the powder storage device 2 is funnel-shaped with an opening at the top. Multiple small holes can be provided on the side wall of the funnel to form a sieve, which facilitates the coffee powder to be thrown out during the high-speed rotation process.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, the funnel-shaped powder storage device 2 is provided with a hole 21. The upper end of the funnel-shaped powder storage device 2 is open, and multiple small holes can be provided on the side wall of the funnel to form a sieve, which facilitates the coffee powder to be thrown out during the high-speed rotation process.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, a speed control knob 13 is provided on the base 1. The speed control knob 13 is electrically connected to the control main board 12. The base includes a control main board, a drive motor, a knob, and a powder storage container. Coffee powder is added to the powder storage container. Different speeds are selected by the knob. The control main board controls the drive motor to rotate the powder storage container at different speeds and for different durations. Due to the different particle sizes, the centrifugal force experienced by the powder is also different. Particles of different sizes are thrown out of the powder storage container (preferably funnel-shaped, with or without holes) by different distances under the action of centrifugal force, and are thus thrown into different areas of the powder receiving trays A, B, and C, thereby achieving powder separation. An air pump is attached to the top. The air pump sucks away the finer powder, which is forced to rotate when passing through the fixed fan blades of the top cover. It is obstructed and decelerated at the outer wall ribs, and is thus collected.

[0032] The above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
