Description

  The present invention relates to a cold / hot pad.

  According to the structure of the cold and hot pad body disclosed in Taiwan Patent No. M288532, as shown in FIG. 1, the surface of the pad body 11 is provided with a long and slender pipe path 12, and one end of the pipe path 12 is used as an inlet end. Let the end be the exit end. An inlet end and an outlet end are provided on the side surface of the pad body 11, a planar outer peripheral surface 124 is formed on the outer periphery of the pipe path 12 and on the opposite side of the surface of the pad body 11, and the inner periphery of the pipe path 12 corresponds to the outer peripheral surface 124. A brazing material 125 is provided on the surface, and a covering member 13 such as a sponge member is provided on the surface of the pad body 11 having the tube path 12 to form a flat surface on the cold / warm pad. Further, an inlet joint 14 and an outlet joint 15 are inserted at the inlet end and the outlet end of the pipe path 12, respectively. After a liquid such as cold water or hot water flows into the pipe path 12 from the inlet joint 14, the liquid is discharged from the outlet joint 15, and returns to the cold temperature device (not shown), so that the cold temperature on the surface of the pad body 11 is uniformly distributed.

Cold pad products help users sleep peacefully on sultry midsummer nights. In addition, it is favored by the public because it can provide a comfortable warmth to users in cold winter. However, the above-described structure of the cold / hot pad body has the following drawbacks.
First, the structure of a conventional cold / hot pad is too complicated. As shown in FIG. 1, the structure of the cold pad described above is composed of a pad body 11, a pipe path 12, and a covering body 13. The pad body 11 is a latex sheet and polyvinyl chloride, and the pipe path 12 is a flexible hose that can be bent. The covering body 13 is a sponge member. Therefore, many materials are used for the cold pad.

  In addition, the pipe path 12 further has a flat outer peripheral surface 124, and quickly transmits the liquid temperature to the pad body 11 to increase the contact area between the pad body 11 and the pipe path 12, thereby improving the effect of the cold pad 11. Let Further, it is necessary to provide the bridging material 125 on the surface corresponding to the outer peripheral surface 124 of the tube path 12 so as to eliminate the influence on the liquid in the tube path 12 due to the compression when the user lies on the pad body 11. In order to realize this effect, when producing a cold pad product, the tube path 12 must first be processed into the required shape. There is a limit to reducing the production cost of the contractor because the pre-operation of the cold / hot pad increases.

  Moreover, the conventional cold / hot pad has too many manufacturing processes. As shown in FIG. 1, the structure of the cold / hot pad is mainly composed of a total of three layers including a pad body 11, a tube path 12 and a covering layer 13. When producing the pad body, the worker first bends the pipe path 12 and places it on the surface of the pad body 11, and then lays a covering body 13 on the surface of the pad body 11 where the pipe path 12 is provided, Cover with a flat surface. That is, the entire production process must be performed by hand. Since the production process cannot be automated, the production efficiency of the cold / hot pad is not good. Furthermore, since there are many manual production processes, the defective rate of the cold / heat pad is increased, which affects the product quality of the cold / heat pad.

According to the prior art, the cold / hot pad body is too thick. As shown in FIG. 1, the above-described cold / warm pad maintains the surface temperature of the pad body 11 by allowing the liquid to flow through the tube path 12 and transmitting the temperature to the pad body 11. Furthermore, the covering body 13 is covered with the pipe path 12 in order to give the cold / hot pad flexibility and elasticity. Due to its thickness, the cold / hot pad requires space for storage and is inconvenient to transport. Thus, the conventional cold / hot pad is inconvenient for storage and carrying.
Taiwan Patent No. M288532 Specification

  An object of the present invention is to provide a cold / heat pad that has a simple production process and a simple structure and improved production efficiency.

  In order to solve the above problems, the cold pad of the present invention is a pad body in which a surface member and a bottom surface member are integrated by high-frequency processing. A water introduction area and a drainage area are provided inside the pad body. One end of the pad body is provided with a water introduction joint and a drainage joint, respectively, and liquids such as cold water and hot water provided outside are introduced into the water introduction area, and the liquid in the drainage area is guided to the outside. The other end of the water introduction area and the drainage area is connected to the first path, and the liquid in the water introduction area is introduced into the drainage area. A plurality of air chambers are provided inside the water introduction area and the drainage area, respectively. A second path is provided between the air chambers, and the liquid in the water introduction area and the drainage area is introduced, and the liquid flows uniformly through the second path to every corner of the water introduction area and the drainage area.

(Effect of device)
Thus, the pad body can uniformly provide the required temperature of the surface by flowing the liquid in a predetermined path. The cold / hot pad of the present invention has a simple configuration and can greatly reduce the production cost and can provide a uniform temperature distribution on the surface of the pad body surface member.

  Each of the front surface member and the bottom surface member is a thin plate formed of a plastic member, and the thin plate can be finished into a pad body by high frequency processing. Further, the pad body is provided with a plurality of air chambers in the water introduction area and the drainage area so as to partition the water introduction area and the drainage area. In this way, the cold pad of the present invention has a simple production process, and the production efficiency of the cold pad can be improved by machine production. In addition, the defective rate of cold / hot pad products can be greatly reduced to achieve the goal of automated production.

  Since the entire pad body of the present invention is made of a plastic member, the weight is light and thin, and it is easy to fold and store the cold / hot pad or store it in a warehouse. Folding and storing the cold / hot pad is convenient for carrying around when you go out and can improve practicality.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
The cold / hot pad according to the first embodiment of the present invention is provided with a water introduction area 21 and a drainage area 22 in the pad body 2 as shown in FIG. Among them, an inlet joint 211 and an outlet joint 221 are respectively provided at one end of the water introduction area 21 and the drainage area 22, and a first path 24 is provided at the other end of the water introduction area 21 and the drainage area 22. The water introduction joint 211 introduces liquid such as cold water or hot water provided from the outside into the water introduction area 21.

  The first path 24 guides the liquid in the water introduction area 21 to the drainage area 22, and the outlet joint 221 discharges the liquid in the drainage area 22 to the outside. Further, a plurality of air chambers 3 are provided in each of the water introduction area 21 and the drainage area 22, and a second path 26 is provided between the air chambers 3. All of the liquid in the water introduction area 21 and the drainage area 22 flows uniformly from this second path 26 to every corner of the water introduction area 21 and the drainage area 22. Thereby, the pad body 2 maintains the liquid introduced into the water introduction area 21 and the drainage area 22 in a uniform temperature distribution.

  Furthermore, in 1st Example of this invention, as shown in FIG. 2, the pad body 2 is connected to the heat exchange apparatus which is not shown in figure, and a heat exchange apparatus provides the liquid of the temperature which a user requires. After the liquid is introduced into the water introduction area 21 through the inlet joint 211, the liquid flows in the second path 26 inside the water introduction area 21 as indicated by an arrow. Since the second paths 26 are electrically connected to each other, the liquid flows uniformly into the water introduction area 21, and the temperature of the liquid is uniformly conducted to the surface of the pad body 2 in the water introduction area 21. Further, the liquid flows from the first path 24 to the second path 26 of the drainage area 22. Since the second paths 26 are electrically connected, the liquid flows uniformly to the drainage area 22, and the temperature of the liquid is uniformly conducted to the surface of the pad body 2 in the drainage area 22. Finally, the liquid is returned from the outlet joint 221 to the heat exchange device, and a heat exchange process is performed in the heat exchange device. In a state where the temperature of the liquid is raised or lowered to a temperature required by the user, this liquid is introduced into the water introduction area 21 through the inlet joint 211 and further heat circulation is performed. Thus, the pad body 2 provides the necessary temperature and maintains that temperature.

  Further, as shown in FIGS. 2 and 3, the pad body 2 includes a surface member 28 and a bottom surface member 29, and the surface member 28 and the bottom surface member 29 are thin plates each finished from a plastic member. This thin plate includes at least the coating layer 4 and the bonding layer 5. In this embodiment, a latex sheet is used for the coating layer 4 and polyvinyl chloride is used for the bonding layer. Since the bonding layer 5 has a thermal fusion characteristic, it is softened at a high temperature and fused together. And after temperature fall, it solidifies and hardens | cures and is united integrally.

Thereby, the bonding layer 5 of the surface member 28 and the bottom surface member 29 is pressed and fused together by high frequency processing, and the pad body 2 is formed from the surface member 28 and the bottom surface member 29. Subsequently, between the surface member 28 and the surface member 29, the water introduction area 21 and the drainage area 22 are partitioned to form the first path 24, the second path 26, and the air chamber 3.
According to the above, since the contractor can automatically produce the cold / hot pad of the present invention by the machine, the production efficiency of the cold / heat pad is improved, and the purpose of mass production with greatly reduced production costs can be realized.

  Furthermore, as shown in FIG. 2 and FIG. 3, after the user lies on the pad body 2, the first path 24 and the second path 26 are pressed by the action supported by the air chamber 3 so that the inner peripheral surface is compressed. Does not hinder the flow of liquid. Further, when the contractor presses and joins the bonding layer 5 by high-frequency processing, some members of the bonding layer 5 are moved to both sides by compression of a high-frequency mold (not shown) and solidified and then supported on both sides of the bonding portion. By forming the portions 51, the bonding portions corresponding to the air chamber 3, the first path 24, the second path 26, and the bonding layer 5 respectively form the support portions 51. The liquid is caused to flow in the first path 24 and the second path 26 in a state where the pressure resistance is enhanced by the support portion 51.
