Suck-back prevention water quality detection pen

Abstract

The invention discloses an anti-suckback water quality detection pen, which comprises a detection pen body. The interior of the detection pen body is sequentially provided with a filter layer, an anti-clogging layer, a detection layer and an anti-suckback device layer, adjacent to each other. There is a buffer layer between the two layers. Beneficial effects of the present invention: through the provided detection pen body, when the tapered suction head is used as a suction detection reagent, when the detection reagent is added, the anti-suckback device can be used to avoid the suction after the suction is completed or the equipment appears. When a fault occurs, the backflow of the detection reagent is caused, which pollutes the raw materials of the detection reagent and wastes resources; in addition, through the set filter layer and the anti-clogging layer, it avoids the need to detect a large amount of impurities in the water quality, and the detection pen The main body causes blockage and damages the use of equipment. The detection pen body has a simple structure, does not need to use more testing instruments, and has high work efficiency.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to an anti-suckback water quality detection pen. Background technique [0002] Water is the source of life. Human beings cannot do without water in their daily life and production activities. The quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Since the establishment of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status; To investigate the pollution degree of water quality and the content...
