Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure, 1 liquid nitrogen vacuum tank, 2 working chambers, 3 gamete carrier racks, 4 liquid inlet electromagnetic valves, 5 exhaust solenoid valves, 6 liquid levels are passed
Sensor, 7 first thermometers, 8 display screens, 9 insulation covers, 10 second temperature meters.
Specific embodiment
Invention is further described in detail in the following with reference to the drawings and specific embodiments:
As shown in Figure 1, memory-type liquid nitrogen fumigating instrument of the invention, including liquid nitrogen vacuum tank 1, working chamber 2, gamete carrier rack
3, liquid inlet electromagnetic valve 4, exhaust solenoid valve 5, liquid level sensor 6, the first thermometer 7, display screen 8, insulation cover 9 and second temperature meter
10；Liquid nitrogen vacuum tank 1 is fixed on plate muscle bracket, can store liquid nitrogen for a long time, and is equipped with level sensing and automatic liquid-feeding function,
Increase operational safety；Working chamber 2 is placed in liquid nitrogen vacuum tank, fixation is connected by screw to, and use well plate format, with liquid
Nitrogen vacuum tank 1 is connected to；Gamete carrier rack 3 is put by working chamber open top, and container is basket with holes, is supported using four feet
Type has adjustable handle, convenient for taking out and installing from working chamber 2；It wherein is equipped with internal rail in the working chamber 2, gamete carries
Body frame 3 can freely adjust height along internal rail.
1 side of liquid nitrogen vacuum tank also sets up display screen 8；Display screen 8 in addition to the display function with liquid level and temperature,
Communication system is additionally provided with to send warning message.
Liquid inlet electromagnetic valve 4 in the present invention is located at the inlet pipe of connection outer liquid nitrogen supply system and liquid nitrogen vacuum tank 1
On, a branch of inlet pipe is equipped with exhaust solenoid valve 5, leads to ambient enviroment, can be avoided according to feed liquor temperature automatic adjustment
High temperature nitrogen enters tank body and brings injury to gamete；Liquid level sensor 6 and the first thermometer 7 in the present invention are threadably secured
Temperature and liquid level in working chamber, in monitoring work chamber 2；Another second temperature meter 10 is located at 4 He of liquid inlet electromagnetic valve
On feed liquor main line before exhaust solenoid valve 5, to monitor feed liquor temperature.

It connects mode, forms confined space with liquid nitrogen vacuum tank when closure.
Work implementation process of the invention is divided into the stifling refrigerating process and transhipment storing process of gamete.
(1) the stifling refrigerating process of gamete:
Outer liquid nitrogen supply system is connected by pipeline with liquid nitrogen vacuum tank, since pipeline is in room temperature shape when unused
State, cannot pull up a horse the feed liquor into the working chamber of liquid nitrogen vacuum tank, and otherwise high temperature nitrogen can damage gamete, thus in pipe-line system before
Side is equipped with thermometer, monitors feed liquor temperature.The pipeline at thermometer rear is divided into two bypass lines, wherein one electric equipped with feed liquor
Magnet valve, another is equipped with exhaust solenoid valve, and wherein corresponding pipeline is controlled for temperature automatic opening show according to thermometer
Whether feed liquor processed.Exhaust solenoid valve is first opened to ambient enviroment and high temperature nitrogen is discharged, and feed liquor temperature is waited to be down to suitable low temperature
Temperature, exhaust solenoid valve are automatically closed, and liquid inlet electromagnetic valve automatically turns on.Certain proper height is risen to liquid level in working chamber,
Gamete cryovial by gamete carrier rack and thereon is put into working chamber, according to the display parameters of display screen, is matched by handle adjusting
Subcarrier frame is along the orbit altitude of working chamber until height needed for being suitble to stifling freezing, then closes insulation cover.It ran
Cheng Zhong, if there is any emergency, emergency warning information can be sent to person liable in time by the communication system in display screen, and
When check failure, continue stifling refrigerating process after reparation.
(2) storing process is transported:
When gamete completes stifling freezing, first closing liquid inlet electromagnetic valve and exhaust solenoid valve, then open insulation cover, by matching
The long handle of subcarrier frame takes out gamete carrier rack and its gamete freezing test tube out of working chamber, finally rapidly freezes gamete and tries
Pipe is put into gamete freezing storage and transportation carrier causes rewarming impaired to prevent from being exposed to gamete in surrounding air.
Finally, it is also noted that listed above is only a specific embodiment of the invention.Obviously, the present invention is gone back
Directly it can export or associate from present disclosure there are many deformation, those skilled in the art and is all
Deformation, is considered as protection scope of the present invention.
