[0027] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a waterproof heat preservation bag comprises a bag body and a bag bottom 1, the bag bottom 1 is oval, the bottom of the bag body is connected to the bag bottom 1, the bag body is gradually flattened upward to form a straight opening at the upper part, the bag body comprises an inner liner cloth 2, a first outer surface cloth 3 and a second outer surface cloth 4, the inner liner cloth 2 is unfolded to be a fan-shaped with a narrow upper end and a wide lower end, the inner liner cloth 2 is wound and the two sides are connected and the lower end of the inner liner cloth 2 is connected to the upper surface of the bag bottom 1, the lower end of the inner liner cloth 2 is connected to the upper surface of the bag bottom 1 by hot pressing and welding, so as to form a seamless connection, the connection between the two sides of the inner liner cloth 2 is also connected by hot pressing and welding, a first accommodating space 5 for accommodating articles is formed between the inner liner cloth 2 and the bag bottom 1, the upper end of the inner liner cloth 2 is connected to the inner side of the first outer surface cloth 3 near the upper end, and the first outer surface cloth 3 comprises a first sheet body 31 and a second sheet 32, the first sheet 31 and the second sheet 32 ​​are symmetrically arranged and the two side edges of the two sheets are correspondingly connected, an opening connected to the first accommodating space 5 is formed between the first sheet 31 and the second sheet 32, the upper end of the second outer fabric 4 is connected to the lower end of the first outer fabric 3, the lower end of the second outer fabric 4 is connected on both sides after being wound around the bag bottom 1, and the lower end of the second outer fabric 4 is connected to the side of the bag bottom 1, a second accommodating space 6 is formed between the first outer fabric 3, the second outer fabric 4 and the inner liner fabric 2, a first thermal insulation body 61 is arranged in the second accommodating space 6, the first thermal insulation body 61 adopts the existing composite thermal insulation sponge, the first thermal insulation body 61 surrounds the outer side of the inner liner fabric 2, thereby surrounding the first accommodating space 5 from the side, forming a good thermal insulation effect on the first accommodating space 5.

[0029] like Figure 2 , Figure 3 and Figure 8As shown, the first outer fabric 3 is connected to a sealing assembly for sealing the first accommodating space 5, and the sealing assembly includes a first magnetic strip 71 and a second magnetic strip 72. The two magnetic strips are soft magnetic strips inside and wrapped with a rubber layer outside. The upper end of the first magnetic strip 71 is connected to the inner side wall of the upper end of the first sheet 31, and the upper end of the second magnetic strip 72 is connected to the inner side wall of the upper end of the second sheet 32. When the first magnetic strip 71 and the second magnetic strip 72 are magnetically attracted to each other, the opening between the first sheet 31 and the second sheet 32 ​​is sealed, thereby sealing the first accommodating space 5. When the first accommodating space 5 needs to be opened, the two magnetic strips are torn apart.

[0030] like Figure 3 As shown, a first reinforcing rib 33 is provided on the first sheet 31 near the upper end, and a second reinforcing rib 34 is provided on the second sheet 32 ​​near the upper end. Connecting cloths are connected to the inner sides of the two sheets. The two connecting cloths and the two sheets form a receiving cavity to accommodate the two reinforcing ribs. The reinforcing ribs are made of flat metal sheets. The extension direction of the first reinforcing rib 33 and the second reinforcing rib 34 is the same as the extension direction of the magnetic strip. The two reinforcing ribs can support the upper part of the first outer cloth 3 to prevent the upper part of the first outer cloth 3 from deforming arbitrarily, reduce the force on the two magnetic strips, and ensure that the first magnetic strip 71 and the second magnetic strip 72 can be quickly fitted and used.

[0031] like Figure 5 As shown, the bag bottom 1 is also connected to an inner bottom lining cloth 11, the inner bottom lining cloth 11 is located in the first accommodating space 5, the inner bottom lining cloth 11 is connected to the upper surface of the bag bottom 1, the edge of the inner bottom lining cloth 11 and the lower edge of the inner liner cloth 2 are connected with a splicing seam, and the inner bottom lining cloth 11 and the inner liner cloth 2 are connected with a waterproof tape 101 to cover the splicing seam, thereby forming a good sealing effect, and the water in the first accommodating space 5 will not flow to the outside.

[0032] like Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, a second insulation body 12 is provided inside the bag bottom 1. The second insulation body 12 also adopts a composite insulation sponge, which forms a good insulation for the first accommodating space 5 from the bottom, thereby improving the insulation effect of the entire insulation bag. A first sealing strip 81 is connected to the outer surface of the lower end of the second outer fabric 4. The first sealing strip 81 is arranged around the bag bottom 1. The lower end of the first sealing strip 81 extends downward to the bottom of the bag bottom 1 and is connected to the bottom of the bag bottom 1, so that the first sealing strip 81 can strengthen the sealing effect of the connection between the second outer fabric 4 and the bag bottom 1. A rectangular bottom pad 13 is provided at the bottom of the bag bottom 1 (the bottom pad 13 can also be set to other shapes, such as an elliptical or wavy shape). The bottom pad 13 is made of wear-resistant material. The lowest point of the bottom pad 13 is lower than the lowest point of the first sealing strip 81, so that when the insulation bag is placed on the ground, the first sealing strip 81 can be prevented from being rubbed, thereby improving the overall service life of the insulation bag.

[0033] like Figure 3 , Figure 6 and Figure 8 As shown, the outer side of the second outer fabric 4 is connected to two opposite handle straps 91, which are respectively arranged on both sides of the bag body. The handle straps 91 are U-shaped, and the two ends of the U-shape are connected to the second outer fabric 4. When the two handle straps 91 are carried together, it is convenient to carry the entire insulation bag. The handle strap 91 is connected to a buckle assembly, which includes a plug-in 921 and a fastener 922. The plug-in 921 is arranged on the handle strap 91 on one side of the bag body, and the fastener 922 is arranged on the handle strap 91 on the other side of the bag body. When the plug-in 921 and the fastener 922 are plugged in, the upper part of the first outer fabric 3 can be bent, and a cover sheet 311 is connected to the upper end of the first sheet 31. After the cover sheet 311 is bent, it can cover the connection between the two magnetic strips of the sealing assembly to prevent water from directly splashing onto the connection between the two magnetic strips, thereby improving the waterproof effect.

[0034] In this embodiment, the bag bottom 1, the liner fabric 2, the first outer fabric 3, the second outer fabric 4 and the first sealing strip 81 are all made of waterproof materials such as TPU composite fabric or PVC composite fabric.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
