[0001] The utility model relates to the technical field of textiles, and particularly relates to a hot water bag knitting sleeve with a heat preservation structure. Background Art

[0002] Hot water bags are mainly divided into three categories: Traditional hot water bags: Such hot water bags are usually empty bags made of rubber or PVC materials, generally square in shape, with a hot water inlet and outlet at one end, and sealed with a spiral plug. When in use, it plays a role in warming by filling with hot water. Water storage type electric hot water bags: There is liquid and a heater inside this kind of hot water bag. After plugging in the power, the liquid in the bag can be heated, so as to achieve the purpose of warming. Electric heating cakes: Their fillers are usually heat preservation cotton. After plugging in the power, the heat preservation cotton is heated for warming.

[0003] The heat storage effect of traditional hot water bags is relatively poor because the heat exchange between the hot water bag and the outside world will cause heat loss. At the same time, after the hot water inside the hot water bag cools down, the warming effect will be greatly reduced, and the service life of traditional hot water bags is relatively short. Due to the limitations of materials and processes, they are prone to wear and aging after long-term use, resulting in damage to the hot water bag.

[0004] Existing hot water bag knitting sleeves are usually knitted from wool yarn. Although wool yarn has good heat preservation performance, it is very difficult to ensure that the air heat insulation performance between the wool yarn layers reaches the best during the design and production process of the hot water bag knitting sleeve. Therefore, its heat preservation effect may not be as expected, especially in the case of relatively low temperatures.

[0005] Therefore, it is very necessary to invent a hot water bag knitting sleeve with a heat preservation structure to solve the above problems. Content of the Utility Model

[0020] To enable those skilled in the art to better understand the technical solution of the present utility model, the following will further introduce the present utility model in detail with reference to the accompanying drawings.

[0021] The present utility model provides a hot water bag knitting sleeve with a heat preservation structure as Figures 1-4 shown, which includes a knitting sleeve 1. A sealing part 6 is arranged at the top of the knitting sleeve 1. Heat insulation parts 5 are arranged on the outer walls of both sides of the knitting sleeve 1. The knitting sleeve 1 is divided into a three-layer structure. A contact layer 12 is arranged on the inner side of the knitting sleeve 1, and a heat preservation layer 13 is arranged on the outer side of the knitting sleeve 1. A base layer 11 is arranged between the contact layer 12 and the heat preservation layer 13 of the knitting sleeve 1. The base layer 11 is woven from polyurethane elastic fiber. Since the polyurethane elastic fiber has excellent elasticity and wear resistance, it helps to improve the durability of the hot water bag knitting sleeve.

[0022] Further, in the above technical solution, mother-child buttons 7 are fixedly installed on both sides of the sealing part 6 near the port position. Drawstrings 8 penetrate through both sides of the sealing part 6. The drawstrings 8 are located below the mother-child buttons 7. The sealing part 6 is integrally formed with the base layer 11 of the knitting sleeve 1. The sealing part 6 adopts the design of mother-child buttons 7 and drawstrings 8, which is convenient for users to quickly open and close the knitting sleeve 1 and prevent the hot water bag from falling out of the knitting sleeve 1.

[0023] Further, in the above technical solution, the heat insulation part 5 is composed of a combination of a wool layer and a cotton cloth layer. The outer side of the heat insulation part 5 is the cotton cloth layer, and the inner side of the heat insulation part 5 is the wool layer. The heat preservation layer 13 is located on the outer walls of both sides of the knitting sleeve 1 and corresponds to the position and size of the heat insulation part 5. The heat preservation layer 13 is also woven with wool material on the base layer 11. The wool material has good heat preservation performance. The design of the position and size of the heat preservation layer 13 corresponding to the heat insulation part 5 enables the heat preservation layer 13 to give full play to its role and improve the overall heat preservation effect of the hot water bag. The heat insulation part 5 is composed of a combination structure of a wool layer and a cotton cloth layer, so that the heat insulation part 5 has excellent heat insulation performance. The outer side of the heat insulation part 5 is the cotton cloth layer, and the inner side is the wool layer, effectively blocking the loss of external heat and reducing the loss of internal heat at the same time.

[0024] Further, in the above technical solution, the contact layer 12 is woven with silk fabric on the inner side of the base layer 11 of the knitting sleeve 1. The contact layer 12 is woven with silk fabric and is arranged on the inner wall of the knitting sleeve 1. Since the surface of the silk is smooth and the traditional hot water bag is made of rubber material, when the hot water bag is put into the knitting sleeve 1, the friction between the outer wall of the hot water bag and the inner wall of the knitting sleeve 1 can be reduced, which is convenient for the hot water bag to be loaded into the knitting sleeve 1. On the outside of the base layer 11 and at a position far from the heat insulation part 5, the knitting thickness of the polyurethane elastic fiber is not less than 5 mm, so as to avoid the thinner thickness of other parts of the knitting sleeve 1 affecting the heat preservation effect and its service life.

[0025] When the hot water bag knitting sleeve with a heat preservation structure provided by the utility model is in use, its working process is as follows:

[0026] First, prepare a traditional hot water bag to ensure that the hot water bag is undamaged and can be used normally. Then, put the unfilled hot water bag into the knitting sleeve 1 to ensure that the hot water bag is completely wrapped by the knitting sleeve 1. After that, inject hot water into the hot water bag and tighten the sealing plug of the hot water bag. Then, fasten the mother - son buckle 7 of the sealing part 6 of the knitting sleeve 1 and tighten the drawstring 8 to make the sealing part 6 shrink, thereby preventing the heat of the hot water bag from escaping through the sealing part 6. When in use, the user inserts the hand from any end of the heat insulation part 5 to achieve the purpose of warming up.

[0027] Since the user's hand often comes into contact with the position of the heat insulation part 5, the heat insulation part 5 is formed by splicing two - layer structures of wool and cotton cloth. The outside of the heat insulation part 5 is cotton cloth. This structural design facilitates the cleaning of the outside of the heat insulation part 5. A waterproof layer is added between the wool layer and the cotton cloth layer of the heat insulation part 5. Thus, during the use process, it can prevent external water from invading the wool layer through the cotton cloth layer. At the same time, the heat preservation layer 13 provided on the outer wall of the knitting sleeve 1 corresponds to the wool layer on the inner side of the heat insulation part 5, and both of them are made of wool material, so that the inner side of the heat insulation part 5 has good heat preservation and heat accumulation effects.

[0028] Only some exemplary embodiments of the utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the utility model, the described embodiments can be modified in various different ways. Therefore, the above - mentioned drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the utility model.
