The invention discloses a special outdoor drinking bag and belongs to the technical field of drinking devices. The drinking bag comprises a bag body and a fastening cap. The drinking body is characterized by comprising a connection base and a water introducing
nozzle, the connection base is formed by connecting a water introducing
pipe and a base, an external thread is arranged on the outer wall of the water introducing
pipe, an internal thread is arranged on the inner wall of the fastening cap, the water introducing
pipe and the fastening cap are connected through the threads, the bag body is connected with the base, and a center through hole is formed in the base; the water introducing
nozzle is composed of a valve element and a
nozzle body, one end of the valve element is embedded in the nozzle body, and the other end of the valve element is embedded in the water introducing pipe. The drinking bag is simple in structure, the connection base has good supporting strength, the overall structural strength of the drinking bag is enhanced,
pressure resistance is improved, the situation that a
water drinking bag is placed in a knapsack and extruded to be damaged can be effectively prevented, the whole drinking bag has
high pressure resistance and is easy to clean and convenient to carry, the quality of water in the drinking bag can be protected, and drinking safety is improved.
