Description

Technical Field

[0001] The utility model relates to the field of cold compress ice bags, in particular to a high-frequency heat-sealing mold structure of an ice bag and a cold compress ice bag. Background Art

[0002] In the prior art, in order to reduce the swelling of the affected limb caused by sports injuries, postoperative rehabilitation, etc., to reduce joint hematoma and pain, and to accelerate the recovery of patients, ice pack products are usually used for cold compress. This product is mainly composed of a main unit and an ice pack. The main unit passes circulating cold water into the ice pack to achieve cold compress. In order to ensure the cold compress effect, the ice pack needs to have a certain pressure.

[0003] Currently, there are two main ways to control the pressure of the ice bag: 1. One is to uniformly control the pressure by changing the gear of the host to control the output size of the water flow. This method has great limitations. For example, some hosts are often equipped with multiple ice bags for different parts, and different ice bags require different pressures. This method cannot meet the needs; 2. The other is to configure an extra layer of air bag on the cold compress ice bag, install an air pump on the host, and achieve pressure control by controlling the expansion degree of the air bag. However, this method will increase the complexity of the overall structure. The host needs to be equipped with an independent air pump pipeline and software design for the joint work of the air pump and water pump, which is not practical.

[0004] Therefore, it is a technical problem to be solved urgently in the art if the structure of the ice bag itself can be optimized so that the ice bag has its own pressure structure and is easy to manufacture and process. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a high-frequency heat-sealing mold structure of an ice bag and a cold compress ice bag.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In the description of the present utility model, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0023] like Figure 1-Figure 2 The high-frequency heat-sealing mold structure of an ice bag shown includes: a base 1, a surrounding edge 2, a baffle block 3 and a separator strip 4.

[0024] A circular peripheral edge 2 is provided on the base 1, and a notch is provided on the peripheral edge 2. A dividing strip 4 is provided in the space surrounded by the peripheral edge 2 and extends to the notch. The dividing strip 4 divides the notch into a water inlet 5 and a drain outlet 6. The baffle block 3 is provided at the drain outlet 6, and gaps are left between the baffle block 3 and the peripheral edge 2 and between the baffle block 3 and the dividing strip 4, respectively. A plurality of water holes 7 are provided on the dividing strip 4.

[0025] When actually processing the cold compress bag, first place the above-mentioned mold on the high-frequency machine and fix it in position, then place a double-layer TPU film on the mold for heat sealing. After the heat sealing is completed, cut the edges of the TPU film and place it in the fixed pad, connect the joint, and the production of the cold compress bag is completed.

[0026] Due to the heat sealing process, the ice bag produced will have welding marks corresponding to the surrounding edge 2, baffle block 3 and dividing strip 4 in the mold, and the naturally defined water inlet 5, drainage outlet 6, water hole 7 and other structures are also the same as the mold. Therefore, in order to facilitate a clear description of the function of the ice bag, the following explanation will be mainly based on the structure of the mold in the figure.

[0027] like Figure 1 As shown, when the water flows, it will flow in from the water inlet 5, then bypass the dividing bar 4, and then flow out from the drain port 6. Since the baffle 3 is provided at the drain port 6, the baffle 3 can block the flow of water, thereby reducing the drainage speed, increasing the amount of water inside the ice bag, and then increasing the pressure of the ice bag. As the pressure increases, the drainage speed gradually increases. When the drainage speed and the water inlet speed reach a balance, the pressure of the ice bag also reaches a balance.

[0028] In practical applications, the size, dimensions and other parameters of the baffle block 3 should be designed and adjusted according to the pressure value required by the ice bag; gaps are left on both sides of the baffle block 3 and the surrounding edge 2 and the dividing strip 4, and the drain port 6 cannot be completely sealed, thereby ensuring the minimum drainage volume of the ice bag, limiting the ice bag pressure from exceeding the design value, and ensuring the service life of the ice bag; and the dividing strip 4 is also provided with a plurality of water holes 7, thereby ensuring that the water flow can flow smoothly in the ice bag at any time, preventing the ice bag from wrinkling after the pressure rises, ensuring the comfort of the ice bag product, and when the ice bag is not in use, the water in the ice bag can flow smoothly to the drain port 6, so that water is not easy to accumulate in the ice bag.

[0029] In further settings, such as Figure 2 As shown, the baffle block 3 is an arc-shaped block protruding toward the inside of the space surrounded by the surrounding edge 2, so that the water flow can be more easily guided by the baffle block 3 to the gaps on both sides, ensuring the smooth flow of the water flow.

[0030] like Figure 2 As shown, the separator 4 includes a longitudinal strip 8 and a transverse strip 9. The longitudinal strip 8 is arranged at the notch and extends inward into the space surrounded by the edge 2. The left and right sides of the longitudinal strip 8 are respectively provided with a plurality of transverse strips 9 arranged in an interlaced manner along the length direction of the longitudinal strip 8. Some of the transverse strips 9 have a small gap between one end and the edge 2 and a large gap between the other end and the longitudinal strip 8. Other transverse strips 9 have a large gap between one end and the edge 2 and a small gap between the other end and the longitudinal strip 8. The small gap forms a water hole 7. The structure of this separator 4 is simple and easy to implement. Of course, the separator 4 can also have other structural forms, which are not limited here. Those skilled in the art can make design adjustments according to actual needs.

[0031] In summary, this scheme has the following characteristics:

[0032] 1. The designed flow block 3 can block the flow of water, thereby reducing the drainage speed, increasing the amount of water inside the ice bag, and then increasing the pressure of the ice bag;

[0033] 2. The designed water hole 7 can ensure that water can flow smoothly in the ice bag at any time under any circumstances, ensuring the comfort and safety of the ice bag product;

[0034] 3. The mold structure is simple and practical, which can effectively reduce the difficulty of manufacturing and processing ice bags. It is easy to change and has strong versatility. It can be designed and adjusted according to the needs of ice bag products, which is convenient for updating ice bag products.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
