Novel water-proof balance

Abstract

The invention provides a novel water-proof balance, comprising a base, a mainboard, a weighing sensor, a weighing disc support, a leveling screw, a power supply, a weighing disc, and a display screen connected with the mainboard, wherein a water storage disc is arranged between the weighing disc and the base; the weighing sensor is directly connected with the weighing disc by passing through the water storage disc; and a plurality of water outlet notches are arranged on the surface of the weighing disc, and two surfaces adjacent to the surface of the weighing disc are slopes; therefore, the structure is favorable for discharging unnecessary water on the surface of the weighing disc. The balance is reasonable in design and simple and convenient for weighing; by adopting the unique structural design of the surface of the weighing disc, the unnecessary water carried on weighed articles can be discharged more easily, so that the weighing result of the articles can be more precise; and the water can be effectively prevented from permeating into the mainboard of the balance, thereby avoiding the short circuit of an inner line, prolonging the service life of the balance, and improving the safety of the balance.

Description

technical field [0001] The invention relates to a balance, in particular to a novel balance with waterproof function, belonging to the technical field of balances. Background technique [0002] The balance is an ancient weighing instrument, which was produced earlier. By the late Spring and Autumn Period, the manufacturing technology of balances and weights had been quite sophisticated. Use bamboo slices as beams, silk threads as buttons, and a copper plate hanging from both ends. Later, because it was troublesome to weigh heavy objects with a balance, it was changed to "Quan", and the balance was only used when weighing small objects. With the advancement of science and technology, the balance, an ancient tool, has also been greatly developed. Differential sign balances, rack balances, resistance balances, single-pan unequal arm mechanical balances, electro-optic resistance balances, electronic balances, etc. have appeared. The types of materials to be measured are becomi...

AI Technical Summary

Problems solved by technology

Electronic balances are electronic precision instruments, and electronic components are prone to short circuits when exposed to water, which directly affects product life

When the electronic balance weighs some living aquatic products, various liquids are easy to leak out of the weighing pan and penetrate into the main board circuit inside the machine, resulting in a short circuit of the circuit
