Description

A kitchen scale with tare weighing function

【Technical field】

The utility model relates to a kitchen scale, in particular to a kitchen scale with the function of peeling and weighing.

【Background technique】

The scale has been a weighing instrument for measuring the mass of objects since ancient times. However, with the continuous development of science and technology, the scale has also developed from the traditional physical scale using the principle of leverage to the current electronic scale, which plays a pivotal role in human daily life. Due to the many and complex structural parts of the existing kitchen scales, the bottom shell and the surface shell need to be connected to each other to form a whole, resulting in a lot of time spent on assembly during production, which seriously affects the production efficiency of the kitchen scale. Now most of the kitchen scales are integrated, which is very inconvenient to install and disassemble, and it is also not conducive to the maintenance and replacement of internal equipment, resulting in a great waste of resources. At present, most of the kitchen scales can only weigh heavy objects without the function of tare weighing. It is very inconvenient to use, the function is relatively simple, and there is no automatic shutdown function. People sometimes forget to turn off the power. , the kitchen scale will always be turned on, which not only wastes resources, but also causes loss to the kitchen scale, reduces the service life, and lacks practicability and usability. For this purpose, we propose a kitchen scale with a tare weighing function.

【Content of utility model】

The main purpose of this utility model is to provide a kitchen scale with the function of peeling and weighing. Since the utility model is equipped with a tray cover on the upper end of the tray, it can effectively protect the tray from loss when it is not in use, and improves the weight of the tray. service life. At the same time, the installation of the tray cover is stable and easy to disassemble, which improves the convenience of people's use. Since the surface shell and the bottom shell are connected by screws, the installation is stable and the disassembly is convenient. At the same time, the equipment inside the shell can be repaired and replaced. To avoid the waste of resources, when the kitchen scale is turned on to zero or the weighing reading is stable and there is no button operation, it will automatically shut down at about 90S, which can effectively prevent people from forgetting to turn off the machine, avoiding the waste of resources and the loss of kitchen scales. Improve the service life of the kitchen scale, through the sensor and circuit board components of the kitchen scale, put an item on the weighing pan when it is turned on, press the "ON/TARE" button, the LCD will display "TARE", and wait for the weight After stabilization, the LCD will display "0" g. At this time, put the item to be weighed on the weighing pan, and then display the weighing weight after tare. It has the function of tare weighing, which can effectively improve the accuracy of item weighing and improve In order to improve the convenience of use, when the load of items on the tray exceeds 5300g, the LCD will display "ooooo", which can clearly let people know that the items are overloaded, avoiding damage to the kitchen scale and improving the service life. The rubber feet can increase the friction between the kitchen scale and the ground, prevent sliding and rollover, and improve the safety of the kitchen scale.

It should be noted that the utility model is a kitchen scale with the function of peeling and weighing. When in use, since the power supply of the kitchen scale is 3V, two AAA batteries can be installed at the bottom of the bottom case 11, and then the batteries can be covered. Cover 12 to prevent the battery from falling off, then press the ON/TARE button on the mirror button sticker 17 on the upper end of the lower case 5, remove the tray cover 1, and place the item on the tray 2. At this time, within 10s, if the weight is stable , the scale can be turned on and reset to 0 to enter normal weighing, otherwise the LCD will display "UNST", and enter normal weighing after 2s. After entering normal weighing, place the object on the scale, and the LCD will display the weight. , the LCD displays "ooooo", which means that the item is overloaded, reminding people to take off the item, avoiding damage to the kitchen scale, and improving the service life. When the machine is turned on, put an item on the weighing pan and press "ON /TARE” key, the LCD will display “TARE”, after the weight is stable, the LCD will display “0”g, then put the item to be weighed on the weighing pan, and the weight after tare will be displayed. The tare range is 100% of the range, but the tare weight and the tare weight are equal to the maximum weighing. Since the kitchen scale has a tare weighing function, it can improve the accuracy of weighing, facilitate people’s weighing, and improve the convenience of use The oz/g button on the mirror button sticker 17 can perform unit conversion, and the unit has a memory function after restarting before shutdown, which is convenient for people to use. When the kitchen scale is turned off, press and hold the oz/g button , and then press the ON/TARE key, it will display "SHOF" and then return to 0, and enter the normal power-on mode.
