Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of precision instruments, in particular to an electronic balance with a cleaning structure. Background Art
[0002] Electronic balances have replaced traditional scales with their high precision, high efficiency, multi-functions and automation, becoming the first choice for weighing and improving operating standards in various fields.
[0003] Although today's technology has many advantages, its disadvantage is that most electronic balances are placed in the external environment. Dust adheres to sensors, agate knives, and scales, changing the weight, causing reading deviations and reduced accuracy. In particular, dust can easily enter the interior of the electronic balance. When encountering humid airflow, the dust can easily become conductive, causing the electronic balance to short-circuit, damaging the equipment, and reducing the service life of the electronic balance. When cleaning the electronic balance, most people use a damp soft cloth to clean it. Water can enter the equipment through the gaps in the electronic balance, causing a short circuit, further reducing the service life of the equipment. Utility Model Content

A slide groove 18 is provided on one side of the shell 1 close to the two slide bars 17. The soft cloth on the cleaning block 16 cleans the electronic scale 5, and the electronic scale 5 is in a state where the back is facing up, so that water stains will not penetrate into the inside of the electronic scale 5, thereby protecting the electronic components inside the electronic scale 5 and further improving the service life of the electronic scale 5.

[0031] Working principle: This device is an electronic balance with a cleaning structure. The cleaning block 16 is provided with a soft cloth. After use, apply the cleaning liquid on the soft cloth, and then manually press the fixed block 9. The fixed block 9 drives the fixed block 2 10 to move downward through the two moving rods 8, and squeezes the two springs 13 on the fixed block 3 7, so that the two springs 13 obtain elastic potential energy. The latch 11 will leave one of the limiting holes 12 of the hollow shaft 6 due to the downward movement of the fixed block 2 10. At this time, the hollow shaft 6 can rotate. The cover plate 3 is rotated by the handle 4, so that the cover plate 3 drives the hollow shaft 6 to rotate 180 degrees through the rotating block 2. Finally, the electronic scale 5 rotates to the inside of the shell 1, and is in a state of the back facing up. Then the fixed block 9 is no longer pressed. At this time, the spring 13 will release the elastic potential energy, so that the fixed block 9 drives the fixed block 2 10 to move upward through the two moving rods 8, so that the latch 11 is re-stuck in another limiting hole 12, and the hollow shaft 6 is limited. , put the electronic scale 5 inside the shell 1 when not in use, with the back facing up, so as to avoid the problem that the electronic scale is placed in the outside world, dust adheres to the sensor, agate knife, and scale plate, changes the weight, and causes reading deviation, thereby improving the accuracy of the equipment, avoiding short circuit of the electronic scale, and prolonging the service life of the electronic scale, and then pull the pull block 15, so that the pull block 15 drives the cleaning block 16 to move through the pull rod 14, and the cleaning block 16 drives the two slide bars 17 to move on the inner surfaces of the two slide grooves 18, and the cleaning block 16 will squeeze the spring 2 19, so that the spring 2 19 obtains elastic potential energy, because the soft cloth on the cleaning block 16 fits the electronic scale 5, the electronic scale 5 can be cleaned when the cleaning block 16 moves, and at this time the electronic scale 5 is in a state with the back facing up, so there will be no water stains penetrating into the inside of the electronic scale 5, which protects the electronic components inside the electronic scale 5 and further prolongs the service life of the electronic scale 5.
