Electric warm water bag and manufacturing method therefor

Abstract

The invention relates to an electric hot water bottle and a preparation method used for the electric hot water bottle. The electric hot water bottle of the invention comprises an independent software internal sleeve and an external sleeve; liquid is memorized in the internal sleeve; the edge of the internal sleeve is also provided with a first connecting part; the position on the external sleeve corresponding to the first connecting part is provided with a second connecting part which is matched with the first connecting part; the first connecting part and the second connecting part are fixedly connected directly with each other between the internal sleeve and the external sleeve by a fixed part, thus leading the connection of the edge of the internal sleeve and the corresponding external sleeve to be non-splittable structure. The electric hot water bag of the structure adopts an independent software internal sleeve, namely, the internal sleeve is individually formed; furthermore, the edge of the internal sleeve and the external sleeve are fixedly connected with each other by the fixed part in a non-splittable way; therefore, the external sleeve can select normal face fabric cloth as the material and has wide selection range; the preparation cost is reduced, furthermore, the type and pattern of the normal face fabric cloth can be designed as diversity so as to enhance the sense of beauty.

Description

technical field [0001] The invention relates to the technical field of electric heating water bags, in particular to an electric heating water bag and a manufacturing method thereof. Background technique [0002] The structure of the electric heating water bag on the market generally includes the outer layer of PVC printed cloth and the inner layer of PVC software. The composite technology is used between the inner layer and the outer layer to form an integral and inseparable structure. The inner layer contact edge seam is sealed, and the sealing edge strip, the outer layer and the inner layer are integrally fixed with a needle thread. The manufacturing method of the electric heating water bag with the above structure is as follows: Firstly, the outer layer of PVC printed cloth is laid on the surface of the inner layer of PVC software, and then the outer layer and the inner layer are directly compounded with a high-frequency machine, that is, an integral seal can be formed. ...

AI Technical Summary

Problems solved by technology

The above-mentioned electric heating water bag and its manufacturing process have the following deficiencies: 1), use PVC calico as the outer layer, and its cost is high; the outer layer and the inner layer adopt an integral composite structure, and the PVC calico outer layer is Its style and pattern have been fixed, so the diversity of its style is limited; 2), affected by the characteristics of the PVC printing outer layer itself, the outer layer and the inner layer must adopt an integral composite structure, which requires high-cost composite equipment; 3), after the outer layer and the inner layer are compounded, it needs to be cut. Affected by the PVC printed cloth of the outer layer, it is easy to form pimples at the edge. Therefore, it is necessary to use fixed side strips around the outer layer where the pi The contact edge seam between the layer and the inner layer is sealed, and the sealing edge strip, the outer layer and the inner layer are fixed as a whole with a needle thread; the structure is complicated and the process is troublesome, which affects the production efficiency and yield of the electric heating water bag to a certain extent
