Abstract

The invention discloses an automatic sample replacing device which comprises a hollow spherical casing. The automatic sample replacing device is characterized in that at least two sampling ports communicated with an inner chamber of the casing are formed on the casing; a rotatable hemispherical switcher and a driving device capable of driving the switcher to rotate around an axial line of the switcher are arranged in the inner chamber of the casing; sampling tubes are arranged in the switcher; and one end of each sampling tube can be connected with one sampling port, and the other end can extend out of the casing along the rotation axial line of the switcher. According to the automatic sample replacing device, the plurality of sampling ports are switched automatically through a stepping motor, so that the purpose of sampling various liquids or gases can be achieved. The automatic sample replacing device provided by the invention has the advantages of simple structure, easiness in use, high efficiency and the like.

Description

technical field [0001] The invention relates to a sampling device for environment detection. Background technique [0002] At present, the sampling operation of multiple gas or liquid samples in environmental monitoring can only be replaced manually. Although this method can handle a variety of emergencies, due to the long sampling time, it takes a long time to switch, which will waste a lot of human resources and time. [0003] Contents of the invention [0004] The present invention provides a solution to the above problems, and provides an automatic sample changing device with simple structure, easy use and high efficiency. [0005] The technical solution of the present invention is to provide an automatic sample changing device, which includes a hollow spherical shell, characterized in that: the shell is provided with at least two sampling ports communicating with the inner cavity of the shell, and the inner cavity of the shell is A rotatable hemispherical switch an...
