[0002] Tobacco virus disease is commonly known as tobacco mosaic. It is the most widely distributed and most common type of disease in tobacco production. When tobacco is infected with the virus, chlorophyll is destroyed, which also seriously affects the quality of the tobacco leaves and deteriorates.

[0003] A Chinese patent discloses a biological sample freezing and transportation device, with the publication number CN205771026U, comprising a refrigerated tank body and a fixed plate, wherein the refrigerated tank body is fixedly connected with the fixed plate, the lower end of the fixed plate is fixedly connected with a storage bottle placement frame, a storage bottle is placed in the storage bottle placement frame, and liquid nitrogen is provided in the refrigerated tank body, the liquid nitrogen level is flush with the bottom surface of the fixed plate, and the upper end of the refrigerated tank body is provided with a tank mouth, which is connected to the tank cover by a thread. The utility model is a biological sample freezing and transportation device, which adopts a new structure, and multiple storage bottle placement frames are set in the liquid nitrogen tank, which makes full use of the space, and can very conveniently put the organisms to be frozen stored and frozen transported in the storage bottles, and then put the storage bottles into the storage bottle placement frame for storage and transportation, so that the biological frozen storage and frozen transportation become simple, convenient, stable and reliable.

[0004] However, there are still the following disadvantages: after the device collects the biological virus sample, the storage bottle is placed inside the placement frame.
