[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] As attached Figure 1 To be continued Figure 6As shown in the embodiment of this utility model, a new type of water-transformable tote bag is provided. Currently, tote bags are mostly made of fabric 3. The fabric 3 can be sewn into a bag 1 that can hold items using needle and thread. Then, bag straps 2 are set on both sides of the opening of the bag 1. The two bag straps 2 are usually of equal length. The two ends of the two bag straps 2 are fixed to the bag 1, forming two openings between them, which makes it convenient for the carryer's hands, arms, etc. to pass through and wear the tote bag. When making the bag pocket 1, adjustment parts 7 can be set on both sides of the opening of the bag pocket 1. Then, multiple limit buckles 10 can be set on both ends of the bag strap 2. When the bag strap 2 is connected to the bag pocket 1, one of the limit buckles 10 on the bag strap 2 can be fastened to the adjustment part 7, thereby realizing the connection between the bag strap 2 and the bag pocket 1, increasing the detachability of the bag pocket 1 and the bag strap 2, facilitating the use of different lengths of the bag strap 2, and making it convenient for people of different ages to carry it by hand, by the arm, or by the shoulder. Next, a water-absorbing layer 4 can be covered on the outer side of the fabric 3. A water-changing fabric 5 that changes color when wet can be set on the outer side of the water-absorbing layer 4, realizing the water-changing and structural adjustment of the tote bag, making it convenient for the tote bag to be used in different scenarios and increasing the versatility of the tote bag.

[0027] Among them, such as Figure 6 As shown, in some embodiments, a water-draining band 6 can be provided on the underside of the fabric 3, the absorbent layer 4, and the water-changing fabric 5. This allows the water to be drained from the lower end of the bag 1 using the water-draining band 6, preventing water accumulation from affecting the color-changing effect and facilitating the drying of the tote bag. This also allows the tote bag to return to its initial state. Meanwhile, the fabric 3 of the tote bag can be made of waterproof fabrics such as nylon or polyester fiber to waterproof the items inside the tote bag. At the same time, the absorbent layer 4 can be made of absorbent fabrics such as cotton or linen to facilitate water retention on the outer surface of the tote bag, prolonging the color-changing time of the tote bag and providing convenience for the use of the water-changing fabric.

[0028] Secondly, in some embodiments, the water-sensitive fabric 5 can use the moisture-sensitive color-changing fabric 3. The color change of existing moisture-sensitive color-changing materials is mainly due to the fact that the humidity in the air causes the structure of the dye itself to change, which in turn changes the absorption spectrum of the dye to the visible light part of sunlight, thus presenting different colors. Different colors can be set according to needs. Furthermore, based on the moisture-sensitive coating on the surface of the water-sensitive fabric 5, different colors and shapes of patterns can be set, which can transmit graphic and pattern information to the outside, increase the functionality of the tote bag, and improve the use effect of the tote bag.

[0029] To facilitate adjustments for different carrying methods of the bag strap 2 and bag pocket 1, such as Figure 4 and 5As shown, in some embodiments, the adjustment part 7 and the pocket 1 can be connected by sewing. Then, a through-hole 8 is provided between the adjustment part 7 and the fabric 3. The through-hole 8 allows the bag strap 2 to pass through, making it convenient for the bag strap 2 to pass through the through-hole 8 between the adjustment part 7 and the pocket 1. Then, using the limiting hole 9 provided in the middle of the adjustment part 7, the bag strap 2 can be fastened to the limiting hole 9 by the limiting buckles 10 provided at both ends, so that the bag strap 2 is connected to the adjustment part 7, and the position of the bag strap 2 is limited, which facilitates the adjustment of different carrying methods by the carrier and increases the usage scenarios of the tote bag.

[0030] Furthermore, multiple limit buckles 10 are spaced apart and evenly sewn onto the bag strap 2. By connecting the limit buckles 10 to the adjustment part 7 at different positions, users can easily adjust the length of the bag strap 2 according to their needs, thereby achieving different wearing methods for the tote bag. In conjunction with the color and pattern changes after the tote bag is water-transformed, it is convenient for the tote bag to match the user's style.

[0031] Furthermore, to accommodate the use of tote bags in different scenarios, such as... Figure 3 As shown, in some embodiments, a pair of pull-out sleeves 11 can be provided on both sides of the opening of the bag 1, and the same drawout port 12 can be provided at the adjacent ends of the two pull-out sleeves 11. Then, a pull-out strap 13 is inserted into each pull-out sleeve 11. One end of the pull-out strap 13 is fixedly connected to the bag 1, and the other end of the pull-out strap 13 passes through the drawout port 12. By tightening the two pairs of pull-out straps 13 inward, the tote bag can be gathered into a structure that is narrow at the top and wide at the bottom. By tightening the two pairs of pull-out straps 13 in the pull-out sleeves 11, the opening of the tote bag can be reduced, the shape of the tote bag can be changed, and different structural forms of the tote bag can be used, increasing the diversity of tote bag shapes and facilitating the use of different tote bag structures.

[0032] And, as Figure 3 As shown, in some embodiments, a tightening ring 14 can be inserted into the end of one pair of pull straps 13, and a connecting ring 15 can be inserted into the end of another pair of pull straps 13. The insertion of the two pairs of pull straps 13 into the tightening ring 14 and the limiting of the ends of the pull straps 13 by the connecting ring 15 facilitates the strengthening of the connection of the pull straps 13, allowing for adjustment of the shape of different tote bag structures. When water is sprayed on the outside of the tote bag, the opening of the tote bag can also be tightened, increasing the safety of the tote bag.

[0033] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
