Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

To achieve the above object, as shown in fig. 1, the present application proposes a weighing calibration device 200 of a bean grinder, which includes a powder receiving container 10 for receiving ground bean powder. At least one load cell 20 configured to detect the bean flour contained in the flour receiving container 10. And a controller electrically connected to the at least one load cell 20 and programmed to determine information about the soy flour based on an output from the at least one load cell 20.

In particular, the bean grinder 100, so called herein, may be a grinder for grinding coffee beans or other legume products, having the functional characteristics of storing whole coffee beans and being able to grind the coffee beans. In the bean grinder 100, the coffee beans can be isolated from the surrounding environment to ensure accurate detection and analysis of the ground coffee powder. The powder receiving container 10 may be a container in a broad scope having a certain cavity for storing or temporarily placing the bean powder. The receptacle of the powder receiving container 10 is adapted to receive ground soy flour when the milling machine 100 is finished or stopped or during the milling process. In the weighing calibration apparatus adapted to the present application, the powder receiving container 10 is considered to be capable of receiving the soybean powder produced by coarse grinding, medium grinding or fine grinding. The coarse grinding is suitable for french press, percolator, etc. Medium grinds are suitable for producing drip filtered coffee. Fine grinding (including ultra-fine grinding) is suitable for espresso coffee machines and for the production of turkish coffee. The weighing sensor 20 may be a pull pressure sensor 21, which is a sensor generally implemented by using a typical wheatstone bridge principle at present, and specifically, may also be a gauge pressure sensor, a differential pressure sensor, an absolute pressure sensor, or the like, and when the structural configuration thereof changes, the numerical value change is implemented by changing the resistance of its own part, and the change resistance is calculated by using other known preset resistances by using the wheatstone bridge principle, so as to calculate the change of the pressure. After calibration and evaluation, the pressure from the receptacle 10 is derived by evaluating the pressure from the pull pressure sensor 21. It will be appreciated that because the receptacle 10 has a known constant mass, any additional mass detected by the mass sensor can be calculated or inferred to be the mass of the legume meal, and the inferred mass of the legume or legume meal can be used as input to one or more algorithms that are calculated and evaluated under the control of the controller to maintain the accuracy of the reading of the receptacle 10. Or, the weighing sensor 20 may be an inductive sensor, and the mass of the powder receiving container 10 is calculated by changing the current through the relative position of an inductive coil arranged on the powder receiving container 10 and further by the current change or the magnetic field change, and the mass of the bean flour in decibels can be obtained in the same way. The load cell 20 may be a combination of multiple sensors or a single sensor. When multiple sensors are used, the controller calculates and calibrates the balance of the values from the multiple sensors to achieve accuracy correction. When a single sensor is adopted, the controller continuously acquires the numerical value of the weighing sensor 20 in a high-refresh-rate acquisition mode, and the numerical value is updated in real time through threshold limitation and an average algorithm. It is understood that the controller may be an integrated circuit integrated on the PCB, or may be separately disposed with the driving motor or the display module, or may be implemented in other conventional manners, which belongs to the prior art and will not be described herein again.

So that when the grinder is placed on top of the load cell 20, the force of its mass is transferred to the load cell 20. In an alternative embodiment, the weighing calibration device 200 of the bean grinder is located directly on top of one or more mass sensors. The sensing base 101 can detect the powder receiving container 10 and the mass of the powder receiving container 10, including the coffee powder therein, without using the structure of the upper weighing platform 40. The updating and optimization may be performed by a controller of the grinding system, a remote server, a remote device, or the like. As the user grinds and adds soy flour to the flour-receiving container 10, the mass of the beans (e.g., the calculated or inferred mass of the beans) will increase. The controller may send this information to a network, cloud service, or other device via itself or other communication module to determine usage information.

The weighing and calibrating device 200 of the bean grinder further comprises a weighing seat 30 and a weighing platform 40 detachably connected with the powder cup 11, at least one weighing sensor 20 is a pull pressure sensor 21, and the weighing platform 40 is suspended on the weighing seat 30 through the pull pressure sensor 21. The weighing platform 40 is detachably matched with the powder cup 11. For example, the powder cup 11 can be made to have a capacity of 1.2L, and it is expected that 1 pound of bean flour can be loaded, see FIG. 2. The pull pressure sensor 21 realizes accurate numerical measurement through the wheatstone bridge principle, and can perform data transmission with the controller in real time and rapidly, thereby realizing accurate weighing. Under the preset condition of the pulling pressure sensor 21, in the working process, the pressure sensor receives the pressure influence from the weighing platform 40, the pressure value of the weighing platform 40 may be the resultant force generated by the weighing platform 40 itself, the powder cup 11 and the bean flour in the powder cup 11 under the action of gravity, therefore, when the mass of the bean flour is nearly zero, the output electric signal of the controller can be subjected to zero adjustment, and the influence caused by the change of the mass of the bean flour smaller than that of the powder cup 11 is eliminated. Meanwhile, the controller has the function of updating the zero setting parameters in real time so as to realize accurate measurement.
