Description

Technical Field

[0001] This utility model relates to the field of abdominal binder technology, specifically to an abdominal binder with constant temperature heating. Background Technology

[0002] An abdominal binder, also known as a postpartum abdominal support belt, primarily refers to a postpartum abdominal support belt. Originally, postpartum abdominal support mainly involved wrapping the abdomen with gauze bandages, hence the common name "abdominal binder." As its use became more widespread, it was increasingly referred to as an abdominal support belt or postpartum abdominal support belt. The market offers various types, including gauze bandage-style, ordinary abdominal binders, multi-piece sets, and specialized functional abdominal binders. However, in cold weather, the surface temperature is low, which can easily cause discomfort and reduce its effectiveness. Therefore, the utility model patent "CN219021937U" proposes "an abdominal binder with a heating function," which uses several heating rods inside to increase the temperature of the binder, improving comfort during winter use.

[0003] However, in the aforementioned patent, heating is achieved by using a heating rod. The heating principle of the heating rod is based on resistance heating, which means that it cannot control the temperature itself and requires an external temperature control device to achieve constant temperature. This increases the cost and the complexity of the abdominal binder structure. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention proposes a constant-temperature heating abdominal binder.

[0005] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0006] A constant-temperature heated abdominal binder includes a base fabric with straps at both ends. The outer ends of the two straps are detachably connected. A first mesh support layer is connected to the lower end of the base fabric, and a second mesh support layer is connected to the upper end of the base fabric. Several mounting holes are vertically provided through the base fabric, and PTC ceramic heating elements are installed in the mounting holes. The hot end of the PTC ceramic heating elements faces the first mesh support layer. A switch is provided on one edge of the base fabric. The switch is connected to several PTC ceramic heating elements via wires, and the switch is also connected to a power cord.

[0007] In a preferred embodiment, a PTC ceramic heating element is installed in the mounting hole via a mounting frame. A ring of slots surrounds the outer side of the mounting frame. The edge of the mounting hole is embedded into the slot and bonded with adhesive. The mounting frame has a vertical central hole. One end of the central hole near the first mesh support layer has a support edge protruding from the inner wall of the central hole. The PTC ceramic heating element is fitted into the central hole, and the hot end of the PTC ceramic heating element is supported on the support edge and connected with adhesive.

[0008] In a preferred embodiment, the base fabric includes a cotton-linen fabric layer, and the upper and lower surfaces of the cotton-linen fabric layer are respectively provided with a first heat-insulating fabric layer and a second heat-insulating fabric layer.

[0009] In a preferred embodiment, a thermally conductive film layer is provided between the base fabric and the first mesh support layer, and the thermally conductive film layer is either a graphene thermally conductive film or a silver-plated thermally conductive film.

[0010] In a preferred embodiment, the outer ends of the two straps are detachably connected by either a snap fastener or Velcro.

[0011] Compared with existing technologies, the beneficial effects are:

[0012] This invention has a simple structure and is easy to use. It uses a PTC ceramic heating element for heating. Due to the constant temperature characteristics of the PTC ceramic heating element, the temperature of the abdominal binder can be kept constant, eliminating the need for external temperature control equipment. This makes the abdominal binder structure simpler and the cost lower. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] A constant temperature heating abdominal binder includes a base fabric 1, with straps 10 connected to both ends of the base fabric 1. The outer ends of the two straps 10 are detachably connected, and the abdominal binder is tied around the waist and abdomen by connecting the two straps 10.

[0019] The lower end of the base fabric 1 is connected to a first mesh support layer 2, and the upper end of the base fabric 1 is connected to a second mesh support layer 3. Both the first mesh support layer 2 and the second mesh support layer 3 are mesh fabric layers with a number of mesh holes, thereby improving the softness and elasticity of the abdominal binder, as well as its high breathability, which facilitates the dissipation of heat.

[0020] The base fabric 1 has a plurality of vertically penetrating mounting holes 11, and a PTC ceramic heating element 6 is provided in the mounting holes 11. The hot end of the PTC ceramic heating element 6 faces the first mesh support layer 2. A switch 8 is provided at one edge of the base fabric 1. The switch 8 is connected to the plurality of PTC ceramic heating elements 6 through wires. The switch 8 is also connected to a power cord 9.

[0021] When the first mesh support layer 2 is close to the body and the switch 8 is turned on, the PTC ceramic heating element 6 is activated. Heat diffuses through the mesh of the first mesh support layer 2 to the surface of the body and is heated by the PTC ceramic heating element 6. Due to the constant temperature characteristics of the PTC ceramic heating element 6, the temperature of the abdominal binder can remain constant, eliminating the need for external temperature control equipment, thus simplifying the structure of the abdominal binder and reducing costs. To easily distinguish the front and back of the abdominal binder, the first mesh support layer 2 and the second mesh support layer 3 are usually set in different colors, or decorative fabric is applied to the surface of the second mesh support layer 3.

[0022] In a preferred embodiment, a PTC ceramic heating element 6 is installed in the mounting hole 11 via a mounting frame 4. The mounting frame 4 has a certain strength, and a slot is provided around the outer side of the mounting frame 4. The edge of the mounting hole 11 is embedded into the slot and bonded with adhesive. The mounting frame 4 has a vertical central hole, and a support edge 5 protruding from the inner wall of the central hole is provided at one end of the central hole near the first mesh support layer 2. The PTC ceramic heating element 6 is matched and installed in the central hole, and the hot end of the PTC ceramic heating element 6 is supported on the support edge 5 and connected with adhesive.

[0023] The mounting frame 4 facilitates the installation of the PTC ceramic heating element 6 into the mounting hole 11.

[0024] In a preferred embodiment, the base fabric 1 includes a cotton and linen fabric layer 12. The cotton and linen fabric has high durability and is not easily damaged. The upper and lower surfaces of the cotton and linen fabric layer 12 are respectively provided with a first heat insulation fabric layer 13 and a second heat insulation fabric layer 14. The first heat insulation fabric and the second heat insulation fabric improve the heat insulation performance of the base fabric 1 and can block the heat emitted by the hot end of the PTC ceramic heating element 6 from passing through the base fabric 1.

[0025] In a preferred embodiment, a thermally conductive film layer 7 is provided between the base fabric 1 and the first mesh support layer 2, and the thermally conductive film layer 7 is either a graphene thermally conductive film or a silver-plated thermally conductive film. The thermally conductive film can make the heat emitted by the PTC ceramic heating element 6 evenly dispersed.

[0026] In a preferred embodiment, the outer ends of the two straps 10 are detachably connected by either a snap fastener or Velcro.
