An automatic liquid stop bag with a bending portion comprises: two outer films, two inner films, a storage area, a discharge channel, a bent portion, an inlet, an outlet and a tear portion. The storage area is formed by coupling the two outer films by hot sealing. The two inner films are disposed between the two outer films and coupled the two inner films by heat sealing to form a discharge channel or the discharge channel is coupled to the two inner films by heat sealing and formed between the two inner films, and the internal sides of the two inner films are not coupled to form the inlet and outlet, and the tear portion is formed at an edge of the two inner films and the two outer films and separated from the two inner films to expose the outlet of the discharge channel.

1. An automatic liquid stop bag with a bending portion, comprising: two outer films;two inner films, vertically overlapped with each other and formed between the two outer films, and having a stop plate pre-installed between the two inner films or a heat resisting material pre-coated between the two inner films;a storage area, coupled to the two outer films, and formed between the two outer films, for storing a liquid;a discharge channel, coupled to the two inner films and formed between the two inner films, and including at least one inlet, a bent portion and an outlet, and the two inner films being coupled to each outer film by heat sealing, and the bent portion being coupled to the inlet and the outlet; anda tear portion, disposed at the outlet of the discharge channel, and exposed from the outlet of a discharge channel after the tear portion is torn open;characterized in that the level of the liquid is forced to rise, when the storage area is squeezed by an external force, so that the two outer films are pulled outward by the liquid to open the inlet of the discharge channel automatically, and the liquid flows along the bent portion of the discharge channel towards the outlet, and after the external force is released, a reaction sucking force refluxes the liquid to the storage area, such that the two inner films at the bent portion of the discharge channel are attached with each other by the reaction force to seal the discharge channel, and when the external pressure is released, the liquid returns from the bent portion to the storage area to produce the reaction force instantaneously to achieve an effect of sealing the discharge channel, and the two inner films at the bent portion are attached to each other to achieve an effect of enhancing the sealing effect. 2. The automatic liquid stop bag with a bending portion as recited in claim 1, further comprising: a filling area, defined between the two outer films, and disposed on a side of the storage area, for filling the liquid to the storage area, and after the liquid is filled to the storage area, a sealing element is provided for coupling the two outer films and sealing the filling area; anda discharge area, defined between the two outer films, and disposed on the side of the storage area, and including the filling area in the discharge area. 3. The automatic liquid stop bag with a bending portion as recited in claim 2, wherein the sealing element is a heat-sealed line or a clip chain formed by heat sealing. 4. The automatic liquid stop bag with a bending portion as recited in claim 2, wherein a side of the two inner films is protruded from the discharge area, and the side of the two inner films is disposed at the filling area or the storage area. 5. The automatic liquid stop bag with a bending portion as recited in claim 1, wherein the bent portion is formed by heat sealing and coupling the two inner films. 6. The automatic liquid stop bag with a bending portion as recited in claim 5, wherein the discharge channel is formed by heat sealing and coupling the two inner films and the two outer films simultaneously. 7. The automatic liquid stop bag with a bending portion as recited in claim 5, wherein the discharge channel is formed by heat sealing and coupling the two inner films and one of the outer films simultaneously. 8. The automatic liquid stop bag with a bending portion as recited in claim 1, wherein the two inner films and the two outer films is heat sealed and coupled to form the inlet, the bent portion and the outlet of the discharge channel. 9. The automatic liquid stop bag with a bending portion as recited in claim 1, further comprising: a plurality of railings disposed in the discharge channel for preventing the liquid from refluxing from the discharge channel. 10. The automatic liquid stop bag with a bending portion as recited in claim 1, wherein a side of the two inner films is protruded from the two outer films and exposed from the two outer films, and the outlet of the discharge channel is formed outside the two outer films. 11. The automatic liquid stop bag with a bending portion as recited in claim 1, further comprising a support area formed by heat sealing and coupling the two outer films and provided for supporting the storage area. 12. The automatic liquid stop bag with a bending portion as recited in claim 1, further comprising an inner bag formed by heat sealing and coupling the two inner films. 13. The automatic liquid stop bag with a bending portion as recited in claim 1, wherein the discharge channel is formed between the two inner films by heat sealing and coupling the two inner films, and the storage area is formed between the two outer films by heat sealing and coupling the two outer films. 14. The automatic liquid stop bag with a bending portion as recited in claim 1, further comprising a stop plate pre-installed between the two inner films or the heat resisting material pre-coated between the two inner film, such that a position of the stop plate or the heat resisting material is not coupled during the heat sealing process to form an inlet and outlet.
