【Embodiment】

The following example is explained further and supplemented to of the present utility model, does not constitute any limit to the utility model System.

As shown in figure 1, the water-jacket typ incubator of the present utility model for being beneficial to humidification includes casing 1, humidifying box 2, water injection box 3。

The casing 1 is hollow structure, and it has the cavity 11 of culture dish holding.Dividing plate is provided with the cavity 11. The setting of the cavity 11 and dividing plate can be referring to known technology.Water jacket 12 is provided between the cavity 11 and casing 1, in water jacket Calandria 13 is provided with 12.The setting of the calandria 13 can be referring to known technology.Broad outlines of the present utility model are, Casing 1 is connected provided with water injection box 3 with humidifying box 2, while the filling pipe of connection runs through water jacket 12, so as to utilize water jacket 12 Water temperature the water in filling pipe is preheated to similar temperature and added into humidifying box 2, so as to ensure that the water newly added will not The temperature in cavity 11 is significantly affected, and avoids opening the risk that glass door added water and brought into bacterium.

Specifically, being provided with humidifying box 2 in the bottom of the cavity 11, the size and shape of the humidifying box 2 are not limited.It is described The open top of humidifying box 2, first entrance 21 and second entrance 22 are provided with the bottom of the humidifying box 2.In the casing 1 Top is provided with water injection box 3.The form and dimension of the water injection box 3 is not limited, and it is designed in favor of water filling for principle.The note Water box 3 should be at sealing when not in use, and when that need to add water, it can be opened and be added water.In the bottom of the water injection box 3 Provided with the first water filling port 31 and the second water filling port 32.The first water filling is provided between the water filling port 31 of first entrance 21 and first Pipeline 41, is provided with the second filling pipe 42, in first water injection pipe between the water filling port 32 of second entrance 22 and second Road 41 is provided with the first normally closed check valve 51, and the second normally closed check valve 52 is provided with the second filling pipe 42.Described One filling pipe 41 and the second filling pipe 42 are made from a material that be thermally conductive, in favor of with water jacket 12 water carry out heat transfer and incite somebody to action Water preheating in filling pipe.To make even heat, the filling pipe 42 of the first filling pipe 41 and second is symmetrical arranged, and It runs through the water jacket 12, and its overwhelming majority is placed in water jacket 12, so as to carry out heat exchange with the water in water jacket 12.To be quick It is heated to the water in the first filling pipe 41 and the second filling pipe 42 identical with the coolant-temperature gage in water jacket 12, first note The filling pipe 42 of waterpipe 41 and second can select the small slender pipeline of cross-sectional area, or flat pipeline, to improve as far as possible It carries out the area of heat exchange with the water in water jacket 12, reduces the heating-up time.Because the water in water jacket 12 is much larger than humidifying box 2 In water, therefore, the water of the low temperature injected in the first filling pipe 41 and the second filling pipe 42 will not significantly affect water Water temperature in set 12, during so as to ensure that the water in filling pipe is heated to mutually synthermal by the water in water jacket 12 in water jacket 12 Coolant-temperature gage will not be reduced substantially.

To ensure that the temperature of the water injected into humidifying box 2 is similar to the temperature of the water in water jacket 12, in first note The first temperature sensor 61 is provided with waterpipe 41, second temperature sensor 62 is provided with second filling pipe 42, Three-temperature sensor 63 is provided with the water jacket 12.To ensure the water of humidifying box 2, provided with detection in the humidifying box 2 The high position sensor 23 of peak level and the low sensors 24 of detection lowest water level.The high position sensor 23 and low level sensing Device 24 can select known level sensor, and it is respectively arranged at the position of equivalent water level.First temperature sensor 61, Two temperature sensors 62 and high position sensor 23 are connected with the check valve 52 of the first check valve 51 and second respectively.Work as institute When stating low sensors 24 and detecting the water shortage in humidifying box 2, it sends alarm signal, reminds user to add water.Now, User can open water injection box 3, the water filling into water injection box 3.The water of injection flows to the first filling pipe 41 and the second filling pipe 42.First filling pipe 41 and the second filling pipe 42 carry out heat exchange with the water in water jacket 12, are heated by the water in water jacket 12. When the first temperature sensor 61 and second temperature sensor 62 are detected in the first filling pipe 41 and the second filling pipe 42 When the temperature of water is identical with the temperature of the water in water jacket 12 or approximate, its described check valve 52 of first check valve 51 and second that links Open, now heated water is flowed into humidifying box 2.When the water in humidifying box 2 reaches peak level, the high position The check valve 52 of the first check valve 51 and second that links of sensor 23 is closed and stops the water filling into humidifying box 2.Thereby, it is just complete Into automatic watering process.During being somebody's turn to do, it is not required to open the glass door of casing 1, thus will not be interacted with outside air, is kept away Exempt to open glass door and bring the danger of bacterium into.In addition, the water added flows through water jacket 12, it is heated without influenceing water by water jacket 12 Water in the temperature of set 12, thus injection humidifying box 2 does not interfere with the temperature in incubator, so that beneficial to the steady of growing environment It is fixed, grow up beneficial to organism.

Although being disclosed by above example to the utility model, scope of the present utility model is not limited to In this, under conditions of conceiving without departing from the utility model, it is similar that each component of the above can be understood with art personnel Or equivalent element is replaced.
