[0015] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] See attached Figure 1 , a liquid collection bag, comprising a bag body 1, the bag body 1 is a square flat structure and a circumferential heat-sealing line 2 is formed at the edge position; a self-sealing joint 3 is fixedly penetrated in the middle of the top of the bag body 1, one end of the self-sealing joint 3 extends into the bag body 1 and the other end is limited to the outside of the bag body 1; a plurality of hanging holes 4 are symmetrically opened at both ends of the top of the bag body 1; a horizontal heat-sealing line 5 is formed at the position below the hanging hole 4 at each end of the bag body 1, one end of the horizontal heat-sealing line 5 intersects with the circumferential heat-sealing line 2 on the side, and the other end of the horizontal heat-sealing line 5 extends horizontally toward the direction of the self-sealing joint 3 and approaches the self-sealing joint 3; a vertical heat-sealing line 6 is vertically formed at a position between the horizontal heat-sealing line 5 and the top edge of the circumferential heat-sealing line 2 on the bag body 1; the vertical heat-sealing line 6 is limited between the hanging hole 4 and the self-sealing joint 3; the horizontal heat-sealing line 5, the vertical heat-sealing line 6 and the top and side edges of the circumferential heat-sealing line 2 together form a closed rectangular area 7; the hanging hole 4 is limited within the rectangular area 7.

[0017] The bag body 1 is composed of two identical rectangular plastic sheets, the four sides of the two rectangular plastic sheets are aligned and the edges of the two rectangular plastic sheets are connected together through the circumferential heat-sealing line 2, thereby forming the bag body 1; the outer wall of the self-sealing joint 3 is heat-sealed and connected to the bag body 1 at the top edge of the circumferential heat-sealing line 2; the horizontal heat-sealing line 5 is parallel to the top edge of the circumferential heat-sealing line 2, and the vertical heat-sealing line 6 is perpendicular to the top edge of the circumferential heat-sealing line 2, the top of the vertical heat-sealing line 6 is perpendicular to the top edge of the circumferential heat-sealing line 2 and the bottom is perpendicular to the horizontal heat-sealing line 5; the horizontal heat-sealing line 5 and the vertical heat-sealing line 6 and the hanging hole 4 are symmetrically arranged on both sides of the self-sealing joint 3; all heat-sealing positions of the utility model are to heat-melt the corresponding positions of the two rectangular plastic sheets of the bag body 1 together to achieve the division of the inner cavity of the bag body 1; the self-sealing joint 3 is a prior art, which is used to inject liquid into the bag body 1, and the injection After the liquid is put in, the self-sealing joint 3 can prevent the liquid from flowing out; the hanging hole 4 is used to hook the bag body 1 as a whole, and a hook or a nail can be used to penetrate the hanging hole 4, so as to fix the bag body 1 at a certain position of the object; the distance from the horizontal heat sealing line 5 to the top of the bag body 1 is less than the length of the self-sealing joint 3; there is a gap between the end of the horizontal heat sealing line 6 close to the self-sealing joint 3 and the self-sealing joint 3 to allow liquid to pass through; the existence of the horizontal heat sealing line 5 can allow the bag body 1 to withstand most of the tension when it is inflated, thereby reducing the tension on the circumferential heat sealing line 2 near the self-sealing joint 3 at the top of the bag body 1, forming a buffering effect, thereby effectively avoiding damage to the bag body 1 and improving the tensile performance of the bag body 1; the horizontal heat sealing line 5 and the vertical heat sealing line 6 need to be set as close to the hanging hole 4 on the corresponding side as possible, so that the area of ​​the rectangular area 7 can be reduced and the capacity of the bag body 1 can be increased.

[0021] The graphene nanomaterial can improve the preservation, antibacterial and UV protection functions of the collection bag, so that the liquid in the bag body 1 can be preserved for a long time.

[0022] When using the utility model, taking the collection of birch sap as an example, a nail is used to fix it on the birch tree through the hanging hole 4, and then the birch sap outlet tube is inserted into the bag body 1 through the self-sealing joint 3, and then long-term collection can be carried out. As the liquid gradually increases, the bag body 1 will become more and more bulging, and the bag body 1 will be squeezed by the internal pressure. The horizontal heat sealing line 5 will bear a large pulling force to protect the circumferential heat sealing line 2 on the top. After the birch sap liquid is collected, the bag body 1 can be taken down from the birch tree for storage or transportation; the graphene nanomaterial can increase the strength of the bag itself, while also playing the role of preserving, inhibiting bacteria, preventing ultraviolet rays, and extending the shelf life of birch sap.
