Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a coffee grinding system that displays the grind setting. Background Technology

[0002] There are two common methods for adjusting the grind size in existing coffee machine grinding systems. One method involves rotating the bean hopper, which in turn rotates the burr adjustment ring, causing the burr to move up and down to adjust the grind size. The advantage of this method is that it allows for a wide range of grind size adjustments. The disadvantage is that the bean hopper needs to be round or similar to a round shape, and the rotation of the bean hopper should not affect normal use or change the appearance of the machine. The other grinding system uses a gear rod to rotate the burr adjustment ring, which in turn moves the burr up and down to adjust the grind size. The advantage of this method is that the shape of the bean hopper is not affected by the grinding system. The disadvantage is that the gear rod is a small gear and the burr adjustment ring is a large gear, resulting in a smaller grind size adjustment range and making it impossible to precisely adjust the grind size of the coffee powder.

[0003] Furthermore, the two methods for adjusting coffee grind size mentioned above can only define a range as coarse / fine grind, without providing specific numbers, leaving consumers to figure it out themselves.

[0004] Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of this invention is to provide a coffee grinding system that displays the grind size settings, allowing consumers to intuitively perceive the specific gear changes. The settings are displayed in numerical form, providing consumers with a more intuitive understanding of the gear settings and facilitating the adjustment of coffee powder coarseness. This enhances operability and practicality, overcoming the shortcomings of existing technologies.

[0006] A grinding system designed for this purpose, characterized in that it includes a control device, a grinding body, a display device electrically connected to the control device and used to display the grinding coarseness, and an adjustment ring rotatably mounted on the grinding body for adjusting the grinding coarseness.

By marking different resistance values ​​at different positions, the position of the upper blade can be accurately identified.

Furthermore, the bean hopper can be designed into various shapes regardless of the grinding setting. Attached Figure Description

[0035] The potentiometer assembly b includes a transmission gear 4 and a potentiometer 5 for detecting the rotational position of the transmission gear 4. The transmission gear 4 is rotatably mounted on the potentiometer 5 and meshes with the adjusting gear 3 for transmission.

[0036] When the adjusting gear 3 rotates, it simultaneously drives the adjusting ring 2 and the transmission gear 4 to rotate. The potentiometer 5 is electrically connected to the control device and transmits the detection signal to the control device.

[0037] Specifically, when the adjusting gear 3 rotates, it drives the adjusting ring 2 to rotate. When the adjusting ring 2 rotates, it drives the upper blade 14 to move up and down, thereby adjusting the grinding gap 16 between the upper blade 14 and the lower grinding wheel 15, thus controlling the coarseness of the coffee powder. At the same time, the adjusting gear 3 meshes with the transmission gear 4 in a tooth ratio. By adjusting the change in resistance of the potentiometer 5 when the gear 3 rotates, the potentiometer 5 can detect the rotation position of the transmission gear 4 through the change in resistance, and then detect the position of the adjusting ring 2, thereby realizing the gear adjustment of the coffee grinding system. The grinding gear is displayed on the visual screen, making it easier to control the coarseness of the coffee powder.

[0038] The display device is an electronic screen; the electronic screen displays the grinding level in real time, making it easier for users to control the grind size, reducing the difficulty of using the grinding system, and improving the consumer's grinding experience.

When the user rotates the knob 6, the adjustment gear 3 connected to it rotates together. At this time, the adjustment gear 3 drives the adjustment ring 2 and the transmission gear 4 to rotate together. The adjustment ring 2 is responsible for controlling the position of the upper blade 14 and adjusting the grinding fineness. The transmission gear 4 of the potentiometer 5 rotates to different positions, causing the resistance value of the potentiometer 5 to change. The change in resistance value is fed back to the control device, which then determines the grinding level and sends the grinding level information to the electronic screen, so that the electronic screen displays the grinding level.

[0041] A rotating shaft 8 is rotatably mounted on potentiometer 5, and a shaft hole 9 is provided on transmission gear 4. The rotating shaft 8 is connected to the shaft hole 9. When transmission gear 4 rotates, it drives the rotating shaft 8 to rotate on potentiometer 5.

Since the potentiometer 5 is not protected and is prone to exceeding the rated stroke, the limit ring 10 is added to limit the stroke of the potentiometer 5 and prevent the potentiometer 5 from being damaged due to exceeding the stroke.
