- 232 is the discharge port
- 3 is the long screw
- 4 is Send beans motor.
- Figure 1 is a schematic diagram of a three-dimensional structure of a grinder provided by a specific embodiment of the present invention
- Figure 2 is a schematic diagram of a grinder provided by a specific embodiment of the present invention Schematic diagram of a partial explosion structure
- Figure 3 is a schematic front view of a bean grinder according to a specific embodiment of the present invention
- Figure 4 is a front view of a bean grinder according to a specific embodiment of the present invention Sectional structure diagram.
- the embodiment of the present invention provides a bean grinder, which can be used for grinding coffee beans or other beans.
- the grinding object is the coffee bean for distance description.
- the bean grinder includes: a bean grinder assembly 1 and Each bean bin 2, the number of bean bins 2 can be selected according to requirements.
- the bean grinder assembly 1 is set at the bottom of the bean bin 2.
- Each bean bin 2 is equipped with a bean feeding screw at the bottom. Before the bean feeding screw rotates, the bean A certain amount of coffee beans is placed in the bin 2.
- the corresponding bean-feeding screw can be rotated to convey to the bean grinder assembly 1.
- the feeding amount can be determined by rotating the rotation of the bean-feeding screw.
- the bean grinder assembly 1 After the bean-feeding is over, that is, when the bean-feeding screw stops rotating, the bean grinder assembly 1 should work for a period of time to ensure that the bean grinder assembly 1 The coffee beans are completely ground and emptied to facilitate the next grinding operation.
- the bean grinder provided in the present application, through the combination of different bean bins 2 and bean feeding screws, not only can convey and grind different coffee beans, but also realize the grinding operation of coffee beans in different proportions, and also has a simple structure , The advantage of low production cost.
- the bean feeding screws at the bottom of the left bean bin 21 and the right bean bin 22 are the same long screw 3.
- the structural characteristics of the screw have the characteristics of unidirectional conveying, that is, when rotating in one direction, the material will be conveyed in the direction of the screw blade. Therefore, when the long screw 3 rotates forward, only the coffee beans in the right bean bin 22 are Is conveyed to the bean grinder assembly 1; when the long screw 3 is reversed, only the coffee beans in the left bean bin 21 are conveyed to the bean grinder assembly 1. It can be understood that when conveying one of the bean bins 2 When coffee beans are being used, the coffee beans in the other bean bin 2 will not fall, and the coffee beans in the other bean bin 2 will fall only when the long screw 3 is reversed.
- the bean feeding motor 4 connected to one end of the long screw 3, the bean feeding motor 4 is used to drive the long screw 3 to rotate, and the ratio of the beans can be controlled by the forward and reverse rotation of the bean feeding screw, such as the A bean selected by the user
- the ratio with B bean is 1:3, then the ratio of forward rotation and reverse rotation time of the bean feeding motor 4 will run at 1:3.
- the forward and reverse rotation can be forward and then reverse, or reverse first. It can rotate forward again, or alternate forward and reverse, as long as the total forward and reverse time ratio is 1:3.
- the bean-feeding screw is horizontally arranged at the bottom of the bean bin 2, that is, the two ends of the bean-feeding screw are rotatably connected to the side wall of the bean bin 2.
- the bean bin 2 can be detachably connected to the grinder assembly

- the inner side walls of 23 are in contact with each other to prevent coffee beans from falling freely into the grinder assembly 1.
- the upper and left sides of the cylindrical feeding channel 23 are each provided with a feeding port 231, and the bottom of the cylindrical feeding channel 23 is provided with an outlet ⁇ 232.
- the detection device can use a Hall sensor
- the detection device is used to detect the number of rotations of the bean-feeding screw
- the control device is respectively connected with the detection device and the bean-feeding motor 4
- the control device is used for
- the number of revolutions detected by the detection device meets the preset demand
- the bean feeder motor 4 is controlled to stop, that is, by controlling the number of revolutions of the bean feeder motor 4, the amount of coffee powder used can be precisely controlled without the user adjusting the thickness of the bean grinder
- the influence of fineness because the traditional method of controlling the amount of coffee powder is controlled by the working time of the grinder motor, but when the thickness of the bean grinder is adjusted by the user, the amount of coffee powder will become different.
- one screw can be used for forward and reverse rotation and one bean feeding motor can control two bean bins for independent bean feeding.
- the independent screw and two bean-feeding motors can also realize the independent bean-feeding operation of the two bean bins. It is also within the protection scope of the present invention.
- Those skilled in the art can also think of adding one By combining the coffee bean bin and the coffee bean conveying device, you can realize one sharpening component and four bean bins, that is, the user can choose four different coffee tastes, and the same can be said for the six or eight coffee taste options.
- you want to implement the three coffee taste schemes add a bean bin, independent screw and bean delivery motor on the basis of Figure 1.
