Constant-temperature water bath oscillator for automatically monitoring and adjusting liquid level of water bath tank

Abstract

The invention provides a constant-temperature water bath oscillator for automatically monitoring and adjusting the liquid level of a water bath tank. The constant-temperature water bath oscillator isused for carrying out constant-temperature oscillation on a sample in a sample detection process, and comprises: the water bath tank, a water supplementing tank, an overflow pipe and a microcontroller. A shaking table is arranged in the water bath tank, a water inlet pipe and a make-up pump are arranged on the water supplementing tank, and the outlet end of the make-up pump is communicated with the water bath tank. One end of the overflow pipe is communicated with the water bath tank, and the other end of the overflow pipe is communicated with the water supplementing tank, and an instantaneousflow rate sensor is disposed on the overflow pipe. The microcontroller is provided with at least one input end and one output end, the instantaneous flow sensor is electrically connected with the input end of the microcontroller, and a relay switch of the make-up pump is electrically connected with the output end of the microcontroller. And the microcontroller starts the make-up pump according tothe received overflow flow, water in the water supplementing tank is circulated back to the water bath tank, and the overflow pipe is kept to have the overflow flow in the whole constant-temperaturewater bath process. The water level in the water bath tank is kept relatively stable in the whole water bath process, and the experiment precision is improved.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to a constant temperature water bath oscillator for automatically monitoring and adjusting the liquid level of a water bath. Background technique [0002] The constant temperature water bath shaker is a biochemical instrument that combines a temperature controllable constant temperature water bath and a shaker. Widely used in plants, biology, microorganisms, genetics, viruses, medicine, environmental protection, food, petroleum, chemical and other scientific research, education departments for precision cultivation of various organisms, genetic engineering research, petrochemical heating and other fields. [0003] Most of the existing constant temperature water bath oscillators place the shaker in the water bath. When the temperature of the water bath is high, the liquid level of the water bath will evaporate and decrease with the prolongation of the water ba...
