Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heating and cooling pad technology, specifically relating to a water-circulating heating and cooling pad. Background Technology
[0002] Heating and cooling pads utilize semiconductors, liquid media, etc., with the main unit heating or cooling these media. The heat is then transferred through pipes inside the pad and into the body for heat exchange, achieving the desired heating or cooling effect. However, existing water-circulating heating and cooling pads have some problems in actual use. When a user sits or lies on the pad, the weight of the body exerts pressure on it. If the pad's support structure is not stable enough, this pressure can cause localized deformation. For heating and cooling pads with internal pipes, this deformation can force the originally regularly arranged pipes to bend or twist, thus affecting the smoothness of water circulation and reducing the heating or cooling efficiency of the pad. Utility Model Content
[0003] The purpose of this invention is to provide a water-circulating heating and cooling pad to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a water-circulating heating and cooling pad, comprising:
[0005] The PVC-bonded fabric consists of two sets of PVC-bonded fabric that are pressed together at high temperature to form a single heating and cooling pad. The surface of the PVC-bonded fabric is pressed with several square grids. Horizontal and vertical channels formed after pressing are left on the surface of the PVC-bonded fabric and between two adjacent sets of square grids. The horizontal and vertical channels are interconnected to allow water to flow into and fill the heating and cooling pad.
[0006] Preferably, the surface of the heating and cooling pad is provided with a water inlet and a water outlet, both of which are connected to a transverse channel.
[0007] Preferably, the heating and cooling pad is provided with a water-blocking strip located in the horizontal and vertical channels.
[0008] Preferably, both the inlet and outlet surfaces are connected to connecting pipes for connecting to an external hot and cold water control tank.
[0009] Preferably, the pressed area on the surface of the heating / cooling pad is provided with an edge sealing strip.
[0010] Preferably, a TPU composite fabric for heat insulation is provided between the two sets of PVC laminated fabrics.
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: A heating and cooling pad is made by high-frequency and high-temperature pressing of PVC laminated fabric. The surface of the pad is covered with high-temperature pressed square grids or other patterns, which can prevent the pad from swelling and deforming, and is also aesthetically pleasing. The internal horizontal and vertical channels are formed by the gaps left after pressing the square grids or other patterns, creating heating and cooling pipes. Water enters the inlet through an externally installed heating and cooling control tank and flows into the horizontal channels via a connecting pipe. High-temperature pressed baffles block the water inlet and outlet, partially blocking the horizontal and vertical channels. Since the horizontal and vertical channels are interconnected, the use of the heating and cooling pad... When cold or warm water flows into the horizontal and vertical channels inside the pad from the inlet, the baffle strips act as a barrier and guide, allowing the water to fill the horizontal and vertical channels before flowing back. This results in a more even and comfortable heating or cooling of the pad. Once the pad is full, the water flows back into the heating / cooling control tank through the connecting pipe at the outlet, thus achieving a constant temperature circulation within the pad and being environmentally friendly. Furthermore, the gaps created by pressing the square grids or other shapes to form the heating / cooling pipes replace the traditional need for pipes inside the pad for water circulation, saving costs and avoiding the problem of pipes being forced to bend or twist due to external forces.
[0012] Furthermore, the heating and cooling pads are flatter, more aesthetically pleasing, and more comfortable, suitable for use as seat cushions, mattresses, sleeping mats, and even outdoors. They replace pipes with horizontal and vertical channels inside the pad, taking up less space and making them easy to fold. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides, for example Figure 1-4 The water-circulating heating and cooling pad shown includes:
[0020] A PVC-bonded fabric 1 is provided, and the two sets of PVC-bonded fabric 1 are integrally formed into a heating and cooling pad 5 by high temperature pressing. The surface of the PVC-bonded fabric 1 is pressed with several square grids 2 at high temperature. The surface of the PVC-bonded fabric 1 and the space between two adjacent sets of square grids 2 are left with horizontal channels 3 and vertical channels 4 formed after pressing. The horizontal channels 3 and vertical channels 4 are interconnected so that water can flow into and fill the heating and cooling pad 5 through the horizontal channels 3 and vertical channels 4.
[0021] The surface of the heating and cooling pad 5 is provided with a water inlet 6 and a water outlet 7, both of which are connected to the transverse channel 3.
[0022] The heating and cooling pad 5 is equipped with a water-blocking strip 8 located in the horizontal channel 3 and vertical channel 4. The water-blocking strip 8, which is formed by high temperature pressing, is positioned between the water inlet 6 and the water outlet 7, and blocks part of the horizontal channel 3 and vertical channel 4. Since the horizontal channel 3 and vertical channel 4 are interconnected, when the heating and cooling pad 5 is used, when cold or warm water flows into the horizontal channel 3 and vertical channel 4 of the pad from the water inlet 6, the water-blocking strip 8 plays a role in blocking and guiding the flow, so that the cold or warm water flows into the pad and fills the horizontal channel 3 and vertical channel 4 of the pad first along the water-blocking strip before flowing back.
[0023] Both the inlet 6 and the outlet 7 are connected to a connecting pipe 10 for connecting to an external hot and cold water tank.
[0024] The surface of the heating and cooling pad 5 is provided with an edge sealing strip 11 at the pressing point. The edge sealing strip 11 can reinforce the edge of the heating and cooling pad 5, enhance the edge strength, and make it better able to withstand various external forces, preventing damage and leakage.
[0025] A TPU composite fabric 12 for heat insulation is provided between the two sets of PVC laminated fabrics 1. When the heating and cooling pad 5 is in hot water circulation mode, the heat generated inside will be transferred to the TPU composite fabric 12 first. Since the TPU composite fabric 12 has certain heat insulation properties, it can slow down the rate at which heat is lost to the outer PVC laminated fabric 1, so that more heat is concentrated inside the heating and cooling pad 5, thereby creating a warm and comfortable environment for the user. Conversely, when the heating and cooling pad 5 is in cold water circulation mode, the TPU composite fabric 12 can also act as a barrier to prevent external heat from entering the heating and cooling pad 5, thus helping to maintain the low temperature inside the heating and cooling pad 5.
[0026] This water-circulating heating and cooling pad is made of PVC laminated fabric 1, which is pressed into a heating and cooling pad 5 using high-frequency high-temperature pressing. The surface of the heating and cooling pad 5 is covered with high-temperature pressed square grids 2 or other patterns, which can prevent the heating and cooling pad 5 from swelling and deforming, and is also aesthetically pleasing. The internal horizontal channels 3 and vertical channels 4 are formed by the gaps left after pressing the square grids 2 or other patterns to create heating and cooling pipes. Water enters the inlet 6 through the externally installed heating and cooling control tank via the connecting pipe 10 and flows into the horizontal channels 3. The high-temperature pressed blocking strips 8 block the water inlet 6 and outlet 7, and partially block the horizontal channels 3 and vertical channels 4. Since the horizontal channels 3 and vertical channels 4 are interconnected, when using the heating and cooling pad 5, the cold water... When warm water flows into the horizontal channel 3 and vertical channel 4 inside the pad from the inlet 6, the baffle strip 8 acts as a barrier and guide, allowing the cold or warm water to flow into the pad and fill the horizontal channel 3 and vertical channel 4 first before flowing back. This makes the heating and cooling pad 5 more evenly heated or cooled and more comfortable. After the heating and cooling pad 5 is full of water, the water in the heating and cooling pad 5 flows back into the hot and cold water control tank from the connecting pipe 10 at the outlet 7. This achieves a constant temperature circulation inside the heating and cooling pad 5 and is environmentally friendly. Moreover, the hot and cold pipes formed by the gaps left after pressing the square grid 2 or other shapes replace the purpose of traditional pipes for water circulation inside the heating and cooling pad 5. This not only saves costs but also avoids the problem of pipes being forced to bend or twist due to external forces.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
