[0006] Preferably, the hose layer includes at least three hoses, namely a first hose, a second hose, and a third hose, wherein the first hose is arranged in a square frame on the outermost side to form an outer hose area; the second hose is arranged in a serpentine, parallel, or spiral manner on the inner side to form an inner hose area; and the third hose is arranged in a square frame between the first and second hoses to form a middle hose area.

[0007] Preferably, the hose layer further includes a circulation terminal, with both ends of the first hose, the second hose, and the third hose connected to the circulation terminal. The circulation terminal has a hollow cavity, and the second hose and the third hose are connected to the hollow cavity.

[0008] Preferably, the first hose is provided with an electric heating wire or filled with a heat-conducting liquid, and the two ends of the first hose are connected to the two ends of the circulation terminal. The second hose and the third hose are filled with heat-conducting liquid, and the two ends of the second hose and the third hose are connected to the same side of the middle of the circulation terminal.

[0009] Preferably, the thickness of the cotton filling layer is relatively uniform in the middle, and the thickness at the edges gradually decreases from the inside to the outside.

[0010] Preferably, the tube layer includes at least three tubes, namely a first tube, a second tube, and a third tube, wherein the first tube is located at the edge of the cotton filling layer, and the second tube and the third tube are located in the middle of the cotton filling layer.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings.

[0018] Reference Figure 1 A waterbed heating blanket, consisting of a hose layer, a cotton filling layer 2, and a blanket surface layer 1, from the inside out.

[0019] Regarding the hose layer

[0020] The flexible tube layer includes at least three flexible tubes: a first flexible tube 3, a second flexible tube 4, and a third flexible tube 5. The first flexible tube 3 is arranged in a square frame on the outermost side, forming the outer flexible tube area. The second flexible tube 4 is arranged in a serpentine, parallel, or spiral pattern on the inner side, forming the inner flexible tube area. The third flexible tube 5 is arranged in a square frame between the first flexible tube 3 and the second flexible tube 4, forming the central flexible tube area. This invention optimizes the arrangement of the flexible tubes, making the arrangement more uniform and effectively reducing the number of bends in the outer flexible tubes, thus effectively reducing discomfort.

[0021] The hose layer also includes a circulation terminal 6. The two ends of the first hose 3, the second hose 4, and the third hose 5 are all connected to the circulation terminal 6. The circulation terminal 6 has a hollow cavity, and the second hose 4 and the third hose 5 are connected to the hollow cavity. The second hose 4 and the third hose 5 are filled with a heat-conducting liquid. The hollow cavity allows the two ends of the hoses to be connected, thus enabling the heat-conducting liquid to circulate within the second hose 4 and the third hose 5. The hollow cavity also allows the hoses to be interconnected, allowing the heat-conducting liquid in the second hose 4 and the third hose 5 to exchange at the hollow cavity. Alternatively, the first hose 3 may contain an electric heating wire, thus enabling the present invention to simultaneously provide electric heating and water heating capabilities. In this case, the first hose 3 is not connected to the hollow cavity. Alternatively, the first hose 3 may be filled with a heat-conducting liquid, in which case the first hose 3 is connected to the hollow cavity. Preferably, the two ends of the first hose 3 are connected to the two ends of the circulation terminal 6, and the two ends of the second hose 4 and the third hose 5 are connected to the same side of the middle portion of the circulation terminal 6. When the first hose 3 is filled with heat-conducting liquid, its two ends are preferably aligned to reduce the circulation resistance of the liquid and to drive the circulation or exchange of the heat-conducting liquid in the second hose 4 and the third hose 5. An electric heating element or a water pump can be installed in the hollow cavity of the circulation terminal 6 to heat the heat-conducting liquid or drive its movement. Preferably, the two ends of the second hose 4 and the third hose 5 are connected to the inner side of the middle portion of the circulation terminal 6, and the power and control lines of the electric heating element or water pump are connected to the outer side of the middle portion of the circulation terminal 6.

[0022] Regarding cotton filling layer 2

[0023] The cotton filling layer 2 has two layers, with a flexible tube layer sandwiched between them. This utilizes the cotton filling layer 2 for insulation while reducing discomfort. Preferably, the thickness of the cotton filling layer 2 is relatively uniform in the middle, gradually decreasing from the inside to the outside at the edges. The first flexible tube 3 is located at the edge of the cotton filling layer 2, while the second flexible tube 4 and the third flexible tube 5 are located in the middle. This variation in the thickness of the cotton filling layer 2 limits the relative positions of the flexible tubes. The circulation terminal 6 is preferably located at a corner of the cotton filling layer 2, thus reducing discomfort. A support tube can be fitted over the first flexible tube 3, with the support tube having a higher rigidity than the flexible tube, thereby shaping the circulation terminal 6 and the flexible tube layer using the first flexible tube 3. The cotton filling layer 2 can be made of materials such as down cotton or space cotton. The support tube can cover the entire first flexible tube 3. However, to reduce discomfort, the support tube can be L-shaped, covering only the bends of the first flexible tube 3. The end of the support tube closest to the circulation terminal 6 is fixedly connected to the circulation terminal 6. To further reduce the discomfort of the support tube or flexible tube, the thickness of the cotton filling layer 2 is preferably not less than the radius of the support tube, or not less than the diameter of the first flexible tube 3. This ensures the thickness of the cotton filling layer 2. The two cotton filling layers 2 can be connected by adhesive bonding or by sewing with thread.

[0024] Regarding the carpet layer 1

[0025] The blanket layer 1 has a matrix of outward-bulging protrusions. These protrusions form an "air chamber," increasing insulation while also cushioning and reducing discomfort. Protrusions can be created by rolling a patterned roller onto the blanket surface, which is existing technology and will not be detailed here. The innovation of this invention lies in the selection of the blanket surface structure, choosing a surface with protrusions and limiting the protrusions to outward bulges. The blanket layer 1 is preferably made of carbon fiber, utilizing the properties of carbon fiber to improve the antistatic, antibacterial, and other physical properties of this invention, and also possessing a certain far-infrared function. The blanket layer 1 has two layers, each located outside one of the two cotton filling layers 2. To further reduce discomfort from the support tubes or hoses, the two blanket layers 1 wrap around the two cotton filling layers 2, and the edges of the two blanket layers 1 are sewn together. A covering fabric is also provided between the two blanket layers 1. The upper edge of the covering fabric is sewn to the upper blanket layer 1, and the lower edge of the covering fabric is sewn to the lower blanket layer 1. Thus, at the edge of the blanket layer 1, a triangular area is formed by the blanket layer 1 and the covering fabric, and this triangular area is filled with spherical polyester fibers. The height of the covering fabric is not less than the outer diameter of the support tube or the outer diameter of the first flexible tube 3. This further reduces discomfort by utilizing the movement of the spherical polyester fibers. The middle of the covering fabric can be bonded to the support tube, thereby guiding the spherical polyester fibers to move towards the support tube when compressed on the outside.

[0026] Preferably, the cotton filling layer 2 has a first seam connecting the two cotton filling layers 2 in the middle, and a second seam connecting the cotton filling layer 2 to the corresponding blanket layer 1 at the edge. This utilizes the unstitched structure at the edge of the cotton filling layer 2 to cooperate with the spherical polyester fibers, allowing the polyester fibers to enter and exit the unstitched area, thereby changing the thickness at that point and reducing discomfort. The outer edge of the cotton filling layer 2 rests against the covering fabric. Preferably, the height of the covering fabric is equal to the maximum distance between the two cotton filling layers 2.

[0027] Preferably, the second suture is located in the depression between the protrusions. This avoids the second suture disrupting the shape of the protrusion.
