High-precision dropper used for chemical industry

Abstract

The invention discloses a high-precision dropper used for chemical industry. The high-precision dropper comprises a liquid accumulating cavity, wherein the interior of the liquid accumulating cavity is movably connected with an extrusion plate; the upper surface of the extrusion plate is fixedly connected with a connecting column which penetrates through the interior of the liquid accumulating cavity and extends toward the outside; one end of the connecting column is fixedly connected with a hand press plate; the bottom part of the hand press plate is fixedly connected with a spring; one end of the spring is fixedly connected with the upper surface of the liquid accumulating cavity; the bottom part of the liquid accumulating cavity is fixedly connected with an inclined plate; the positionof the center of the inclined plate is provided with a liquid accumulating opening; and the bottom end of the liquid accumulating opening is fixedly connected with a straw. The high-precision dropperprovided by the invention has the following advantages: the effects of liquid suction and liquid discharging through upward-and-downward movement in the liquid accumulating cavity are achieved; the drive power for the extrusion plate to continuously move up is reached; the effect of liquid suction is improved; the action of fixing the straw is reached; the precision of the dropper can be effectively reinforced; the problem of incapability of reaching the liquid accumulating cavity for the extrusion plate due to the height of the spring can be effectively reduced; and the problems of durabilityand precision of the dropper are effectively solved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a dropper with high precision for chemical industry. Background technique [0002] The relationship between human beings and chemical industry is very close, and it has spread to all aspects of life. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing and transportation to spiritual life such as culture, art and entertainment, chemical products are required to serve them. Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. Early human life relied more on direct utilization of natural substances. Gradually, the inherent properties of these substances cannot meet the needs of human beings, so various processing technologies have been produced to conscio...
