Electronic scale capable of automatically proportioning weights

Abstract

An electronic scale capable of automatically proportioning weights, consisting of a base (1), a tray (2), weight sensors (13), a console (3) and a calculation and storage unit (12). A weighing area (15) of a panel of the console (3) is provided with a main ingredient weight display (4), an on-off / main ingredient zero setting key (8) and a main ingredient weight memory key (9), and a proportioning area thereof is provided with a proportion display, a weight display (6) for an additional ingredient to be added as well as an increase / decrease prompt (7) thereof, a proportion setting numeric keyboard (10) and a proportion / additional ingredient weight zero setting key (11). By means of a software function of the calculation and storage unit (12) combined with a hardware circuit, the electronic scale allows for key commands and proportion setting, calculates and outputs real-time measurement data, and displays in real time the weight P of an additional ingredient to be added as well as an increase / decrease prompt (7) thereof. A weighing process comprises: measuring the net weight Z of a main ingredient; recording Z as a basic value; and inputting a proportion coefficient B. As the weight P of the additional ingredient to be added is equal to the weight P1 of the additional ingredient that has been added minus B multiplied by Z, i.e. P=P1-B×Z, an increase / decrease prompt value with regard to P will be displayed in real time as P1 is increased / decreased. When p = 0, the weight P1 of the additional ingredient that has been added exactly reaches a required additional ingredient weight defined by B×Z.

Description

An electronic scale with automatic weight proportioning 1. Technical Field

[0001] The invention relates to an electronic scale, in particular to an electronic scale device capable of automatically proportioning by weight. 2. Background Technology

[0002] In production across various industries and in everyday life, the entire production process from raw materials to finished products involves a variety of ingredient ratios. When using electronic scales with only a weighing function to perform these ratios, the process requires additional recording and calculations, making the process cumbersome and error-prone. For example, the commonly used electronic kitchen scale has been limited to a single weighing function since its invention, with no substantial functional improvements over the decades.

[0003] Existing electronic scales can be roughly classified into the following categories: weighing electronic scales, whose main function is to measure and display the weight of items; pricing electronic scales, which add unit price data to the weighing function and then display the weight, unit price and their total; counting electronic scales, which generally have the functions of the first two types of electronic scales, first measure the weight of a single item and then measure the total weight of multiple items to calculate and display the number of items, etc.

[0004] 3. Summary of the Invention

[0005] Existing electronic scales primarily consist of a base, tray, weight sensor, console, and a computing and storage unit. The tray is fixedly connected to the base via the weight sensor, which is then connected to the computing and storage unit via cables to transmit measurement data. The computing and storage unit is also connected to various components in the console via cables, receiving operational instructions and displaying necessary values.

[0006] Based on existing electronic scales, the present invention provides an electronic scale device that can automatically proportion ingredients by weight. This solves the inconvenience of having to weigh, record, and calculate multiple ingredients during the proportioning process. It also adds a new branch to the electronic scale category: an automatic weight proportioning electronic scale.

[0007] When using this automatic proportioning electronic scale, the raw materials need to be divided into main materials and auxiliary materials, that is, the raw materials used as the basis for weight calculation are the main materials, and the auxiliary materials added according to different proportions of the main materials are the auxiliary materials.

[0008] The technical solution adopted by the present invention to solve its technical problems is as follows: the control panel of the weight automatic proportioning electronic scale is divided into a weighing area and a proportioning area, wherein the weighing area has a main ingredient weight display, a switch / main ingredient zeroing key, and a main ingredient weight memory key; the proportioning area has a proportion display, a display of the weight of the ingredients to be added and its increase or decrease prompt, a proportion setting numeric keyboard, and a proportion / ingredient weight zeroing key. The software function of the calculation storage unit is combined with the hardware circuit to realize the calculation and output of key instructions, proportion setting, and real-time measurement data, and the value of the weight P of the ingredients to be added and its increase or decrease prompt are displayed in real time; after pressing the switch / main ingredient zeroing key (for power on and first tare), the net weight Z of the main ingredient is added and measured and displayed. Press the main ingredient memory key to record Z as the base number, press the ratio / ingredient weight zero key to reset the ratio coefficient and the weight of the ingredients to be added to zero at the same time (twice peeling), enter the required ratio coefficient B through the numeric keyboard and display it, Z multiplied by B can be calculated to get the weight P of the ingredients to be added, then P is equal to the weight of the added ingredients P1 minus B multiplied by Z, that is, P = P1-B×Z, in this way, the weight P of the ingredients to be added will be displayed in real time with the increase or decrease prompt of the added ingredient weight P1. When P is displayed to 0, it means that the weight of the ingredients P1 added just reaches the ingredient weight required by B×Z. When P is less than or greater than 0, the weight P of the ingredients to be added will have a corresponding increase or decrease prompt.

[0009] When you need to add another ingredient after completing one ingredient, just repeat the following steps from pressing the ingredient / ratio reset key in the above steps, and so on, as many times as you want, until you are done.

[0010] The beneficial effects of the present invention are that various raw materials and ingredients can be proportioned more conveniently and accurately in production and daily life, no additional records and calculations are required, errors can be reduced, the structure is reasonable, and the operation steps are simple. IV. Description of the Figures

[0011] The present invention will be further described below with reference to the accompanying drawings and examples.

[0012] FIG1 is a schematic diagram of the top of the present invention;

[0013] FIG2 is a side schematic diagram of FIG1 ;

[0014] Figures 3-1 to 3-11 are circuit diagrams of the present invention; V. Specific Implementation Methods

[0015] In the specific embodiments shown in Figures 1, 2, and 3-1 through 3-11, the automatic proportioning electronic scale primarily comprises a base 1, a tray 2, a control console 3, a weight sensor 13, and a computing and storage unit 12. Tray 2 is fixedly connected to base 1 via weight sensor 13. Tray 2 is completely mounted on weight sensor 13, with no other contact with base 1, and sufficient clearance is left to ensure that tray 2 does not contact base 1 during weighing. Weight sensor 13 is connected to computing and storage unit 12 via cable 14, which in turn is connected to power port 17 and various components within control console 3 via cables.

[0016] The control panel 3 is divided into a weighing area 15 and a proportioning area 16. The weighing area 15 includes a main ingredient weight display 4, an on / off / main ingredient zero reset button 8, and a main ingredient weight memory key 9. The proportioning area 16 includes a proportion display 5, a display showing the weight of the ingredients to be added 6, an ingredient increase / decrease indicator 7, a numeric keypad for proportion settings 10, and a proportion / ingredient weight zero reset button 11. Furthermore, the control panel 3 also features a power port 17, a calculation and storage unit 12, and a voice prompt 18.

[0017] When using this automatic proportioning electronic scale, the raw materials need to be divided into main materials and auxiliary materials, that is, the raw materials used as the basis for weight calculation are the main materials, and the auxiliary materials added according to different proportions of the main materials are the auxiliary materials.

[0018] By combining the software functions of the calculation and storage unit 12 with the hardware circuit, key commands, ratio settings, and the calculation and output of real-time measurement data through the weight sensor 13 are realized, and the real-time change of the weight P of the ingredients to be added and the increase or decrease prompt is realized, and the weight display 6 of the ingredients to be added and the ingredient increase or decrease prompt 7 are displayed in real time. The steps are as follows: (1) Place the container on the tray 2, click the switch / main ingredient zero key 8 to turn on and zero, which is commonly known as the container "peeling" state, then add the main ingredient to the container, measure the net weight Z of the main ingredient and display it on the main ingredient weight display 4, click the main ingredient weight memory key 9 to record and return the main ingredient net weight Z data to the calculation and storage unit 12. (2) Click the ratio / ingredient zero key 11 to simultaneously zero the ratio display 5 and the weight display 6 of the ingredients to be added, which is a second tare, enter the required ratio coefficient B through the numeric keypad 10 and display it on the ratio display 5, and Z multiplied by B can be calculated to obtain the weight P of the ingredients to be added. (3) Then, the weight P of the ingredients to be added is equal to the weight P1 of the ingredients already added minus B times Z, that is, P = P1 - B × Z. In this way, P will be displayed in real time on the weight display 6 of the ingredients to be added with an increase or decrease prompt as the weight P1 of the ingredients already added increases or decreases. When the P display value reaches 0, it means that the weight P1 of the ingredients already added just reaches the weight P of the ingredients required by B × Z. When P is less than or greater than 0, the weight of the ingredients to be added will be displayed with a corresponding increase or decrease prompt 7.

[0019] When you need to add another ingredient after completing one ingredient, repeat the following steps from (2) pressing the ingredient / ratio reset key 8 in the above steps, and so on, unlimited times, until completion.

[0020] The operation steps are performed by the software function of the computing storage unit 12 in combination with the voice prompter 18, and there are corresponding necessary voice prompts.
