It should be noted that, the temperature value of the solution in the constant temperature water tank is obtained in real time through the temperature sensor arranged in the heat preservation cover or the constant temperature water tank, when the temperature value of the solution in the constant temperature water tank is smaller than the preset temperature value, the air energy water heater is started at the moment, the air energy water heater heats the solution inside the air energy water heater to reach the preset temperature, the solution at the preset temperature flows out of the water storage tank, the solution enters the water inlet pipe from the water storage tank and further enters the constant temperature water tank, and the water solution at the constant temperature water tank lower than the preset temperature flows back into the water storage tank from the overflow port at the moment, so that the whole water solution can be recycled, the utilization rate of resources is further improved, and although the solution in the constant temperature water tank is lower than the preset temperature, when the solution is heated to the same temperature, the required electric energy is less, so that the electric energy can be saved.
Further, in a preferred embodiment of the present invention, the method for using the thermostatic device for the material biodegradation test further comprises the following steps:
and if the upper cover of the thermostatic water tank needs to be opened, opening an air valve control switch of the thermostatic water tank, so that the upper heat-insulating cover of the thermostatic water tank is automatically opened.
In conclusion, compared with the prior art, the constant-temperature water tank has a better heat preservation effect, and can reduce the loss of electric quantity and water in the tank at the same time, so that the water in the constant-temperature water tank can be recycled, the recycling of resources is promoted, and the test cost is reduced. The air energy water heater is used, when the temperature of the solution in the constant-temperature water tank is lower than the preset temperature, the water with the preset temperature is introduced into the constant-temperature water tank, the problem that the heating pipe is burnt out due to the fact that the liquid level is lower than the heating pipe when the constant-temperature water bath kettle carries out water bath heating is solved, and the air energy water heater is simpler and more convenient to use. The heat preservation cover is provided with the air valve control switch, so that on one hand, physical consumption of workers can be effectively reduced, and on the other hand, test data are more accurate. On the other hand, the air energy water heater host machine provided by the invention can radiate cold air to reduce the indoor temperature, so that the use power of an indoor air conditioner is reduced, a comfortable environment is provided for workers, the utilization rate of energy is improved, and the test cost is saved.
