Description of reference numerals: 1, casing；2, water pump；3, heater；4, electromagnetic valve.
Detailed description of the invention
With reference to Fig. 1, a kind of water isolation type constant incubator, the sidewall of casing 1 is provided with water pump 2 and heater 3, wherein water pump 2 is positioned at above heater 3, and the outlet pipe of water pump 2 is connected with heater 3, and the water inlet pipe of water pump 2 is connected with outside tank.Heater 3 is connected by the pipeline arranged below at heater 3 with the water filling port on water isolation type constant temperature culture box body 1.Pipeline between the water filling port of heater 3 and casing 1 is provided with the electromagnetic valve 4 controlling this pipeline break-make.
It addition, be provided with the first liquid level sensor and the second liquid level sensor in the water jacket within casing 1, wherein the first liquid level sensor is positioned at below the second liquid level sensor.Water level detecting module is constituted with reference to Fig. 2 and Fig. 3, the first liquid level sensor and the second sensor and comparator A1.First sensor is connected with the positive input of comparator A1, the reverse input end input reference voltage Vref1 of comparator A1, second liquid level sensor is connected with the positive input of comparator A2, the reverse input end of comparator A2 and input reference voltage Vref2, the base stage of the outfan amplifying triode Q1 of comparator A1 connects, the colelctor electrode of amplifying triode Q1 is connected with the relay coil controlling water pump 2 and heater 3 startup, the outfan of comparator A2 is connected with the base stage of amplifying triode Q2, the colelctor electrode of comparator A2 is connected with the relay coil KM2 controlling water pump 2 and heater 3, wherein reference voltage V ref1 is less than reference voltage V ref2.
The principle of this partial circuit work is as follows: in the process of water isolation type constant incubator work, the moisture loss in water jacket, water level decreasing.When water level makes lower than the height of the first liquid level sensor, first liquid level sensor exports a level signal i.e. the first feedback signal, the amplitude of the first feedback signal is more than reference voltage V ref1, now comparator A1 exports high level signal, the base stage of amplifying triode obtains electric, amplifying triode Q1 is in magnifying state, the amplification metapedes of the amplified audion Q1 of electric current that power Vcc provides is to drive relay coil KM1 to make its adhesive, after KM1 adhesive, water pump 2 and heater 3 start simultaneously at operation, water pump 2 injects water in heater 3, water reinjects in water jacket after being added in heater 3.When there being water to inject water jacket, water level in water jacket rises, when water level rises to the position of the first liquid level sensor, owing to the normally opened contact of relay coil KM1 is connected with power supply and the outfan of comparator A1, making relay K M1 have self-retaining function, now, relay coil can't disconnect, and it being to continue with keeping attracting state, water level continues to rise.When water level rises to the position of the second liquid level sensor, relay coil KM2 adhesive, owing to the normally-closed contact of relay coil KM2 connects between the power supply of relay coil KM1 and KM1, after relay coil KM2 adhesive, relay K M1 power-off.Now, water pump 2 and heater 3 dead electricity (in Fig. 3, K11 and K22 represents the normally opened contact of KM1 and the normally-closed contact of KM2 respectively) out of service simultaneously.Pass through the program, it is possible to by the water lev el control in water jacket within the specific limits, it is prevented that occur that because water level is too low water jacket adds the situation of heat pipe dry combustion method；Also the situation that the headspace deficiency of water jacket occurs can be prevented because water level is too high.
It practice, when to water jacket moisturizing, if the temperature of water supplemented differs bigger with the water temperature in water jacket, can make the water level in water jacket that fluctuation occurs, be unfavorable for the carrying out of constant temperature test.For solving this problem, the effect of heater 3 of the present utility model is to be preheated by the water injected in water jacket, after making water temperature in heater 3 equal with the water temperature in water jacket, just inject water in water jacket, so, when just can prevent from adding water, there is the situation of fluctuation in the water temperature in water jacket.Concrete implementation mode is: be provided with the first temperature sensor in heater 3, is provided with the second temperature sensor in water jacket.First temperature sensor and the second temperature sensor constitute water temperature detection module.First temperature sensor and the second temperature sensor are connected with the forward of comparator A3 and reverse input end respectively.The outfan of comparator A3 is connected with the relay coil controlling electromagnetic valve 4 conducting.When the water temperature in the equal i.e. heater 3 of the voltage that the first temperature sensor and the second temperature sensor export is equal with the water temperature in water jacket, comparator A3 exports a level signal, the relay controlling electromagnetic valve 4 logical obtains electric, electromagnetic valve 4 turns on, and the pipeline between heater 3 and casing 1 water filling port is switched on.Water after preheating injects in water jacket；If the water temperature in water jacket is unequal with the water temperature in heater 3, reset is turned off by electromagnetic valve 4, and water just cannot inject in water jacket.It addition, the outfan of comparator A2 is connected with the relay controlling relay shutoff.When the water level in water jacket rises to the position of the second level sensor, electromagnetic valve 4 turns off, and water pump 2 and heater 3 quit work simultaneously simultaneously.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
