Description

Technical Field

[0001] This utility model relates to the field of mattresses, and more particularly to a temperature-adjustable mattress system. Background Technology

[0002] Water circulation is a common method for temperature regulation in mattresses. For example, Chinese utility model patent ZL201921347218.9 (authorization announcement number CN211608886U) discloses a water mattress with temperature regulation function, including an adjustable temperature mattress body, a base, a water tank, a filling and emptying water pipe, a liquid extraction pipe, and a two-way water pump. It also includes a liquid limiting mechanism, a water injection pipe, a cover, and a backrest. The adjustable temperature mattress body is installed on the inner bottom wall of the base, the bottom of the base is connected to the top of the water tank, the bottom of the filling and emptying water pipe is connected to the inner cavity of the water tank, and the top of the filling and emptying water pipe is connected to the inner cavity of the adjustable temperature mattress body. It is evident that existing temperature-adjustable mattresses have complex structures.

[0003] Furthermore, existing temperature-adjustable mattresses generally achieve temperature regulation through active adjustment, which is not only cumbersome but also involves complex temperature regulation structures. Examples include Chinese utility model patent No. ZL202323095069.0 (authorization announcement No. CN222171751U) and Chinese invention patent No. CN202411901765.2 (publication No. CN119700410 A). Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a temperature-adjustable mattress system that is simple in structure, has a simple temperature adjustment method, and has a good adjustment effect, in contrast to the existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a temperature-adjustable mattress system, including a mattress that can deform under pressure, characterized in that the mattress is provided with water pipes, which extend along the length direction of the mattress and are spaced apart along the width direction of the mattress; the mattress is also provided with limiting structures corresponding to the water pipes one by one.

[0006] In the initial state, the cross-sectional area of ​​each water pipe is A. When the mattress is compressed and deformed, each water pipe deforms along with the mattress until it is limited by the corresponding limiting structure and is in a deformed state. In the deformed state, the cross-sectional area of ​​each water pipe is B, and B > A.

[0007] Furthermore, in the initial state, the cross-sectional shape of each water pipe is an ellipse extending vertically; in the deformed state, the cross-sectional shape of each water pipe is a circle. With the perimeter unchanged, the area of ​​a circle is greater than that of an ellipse; therefore, deforming the cross-sectional shape of each water pipe from an initial ellipse to a circle increases the cross-sectional area of ​​each water pipe.

[0008] Furthermore, the mattress is provided with a first installation channel corresponding to each water pipe. Each first installation channel extends along the length of the mattress and allows the corresponding water pipe to be installed along its own length.

[0009] Each limiting structure includes a limiting plate, which extends along the length of the mattress and is installed in the corresponding first installation channel along its own length. Each limiting plate is located below its corresponding water pipe.

[0010] Furthermore, the cross-section of each limiting plate is arc-shaped. In the initial state, the cross-section of each water pipe is a long strip extending vertically. In the deformed state, the lower outer surface of each water pipe aligns vertically with the inner surface of the corresponding limiting plate along its length. The installation of each water pipe and each limiting structure within the mattress is achieved by setting a first installation channel. Since the cross-section of each limiting plate is arc-shaped, during the process of the mattress deforming under pressure, and the limiting plates deform accordingly, each limiting plate can limit the water pipe, preventing further deformation and the water pipe from becoming a long strip extending along the width of the mattress.

[0011] Furthermore, the cross-section of each limiting plate is semi-circular, and its size matches the cross-sectional area of ​​the corresponding water pipe in the deformed state. Each limiting plate and its corresponding water pipe are positioned vertically opposite each other. This allows the limiting plates to better restrict the corresponding water pipe in the deformed state, and to confine the water pipe to a circular cross-sectional shape, thereby maximizing the cross-sectional area of ​​each water pipe in the deformed state (a circle has the largest area for the same perimeter), thus improving the temperature regulation effect on the mattress.

[0012] Furthermore, the mattress includes a first pad layer that comes into contact with the human body and a second pad layer located beneath the first pad layer. The second pad layer has recessed first mounting grooves corresponding to each water pipe. Each first mounting groove extends along the length of the mattress and, together with the first pad layer covering the second pad layer, forms the aforementioned first mounting channel.

[0013] Each water pipe is fixed to the lower surface of the first padding layer, and each limiting plate is fixed to the inner bottom surface of the corresponding first mounting groove. In the initial state, the lower end of each water pipe is in contact with the corresponding limiting plate. This creates first mounting channels in the mattress, facilitating the installation of each water pipe and each limiting plate, and ensuring the stable installation of each water pipe and each limiting plate.

[0014] Furthermore, each of the water pipes is bonded to the lower surface of the first padding layer along its own length, and the lower surface of each limiting plate is bonded to the inner bottom surface of the corresponding first mounting groove along its own length. This further ensures the stable installation of each water pipe and each limiting plate in the mattress.

[0015] Furthermore, it also includes inlet and outlet water pipes. The inlet of each water pipe is fluidly connected to the outlet of the inlet water pipe, and the outlet of each water pipe is fluidly connected to the outlet of the outlet water pipe. This allows the water flow in each water pipe to circulate, facilitating better regulation of the mattress temperature.

[0016] Furthermore, the first end of the mattress is provided with a water inlet connector, which extends along the width of the mattress. One side has a water inlet interface connected to the outlet of the water inlet pipe, while the other side has water outlet interfaces spaced along its length, each corresponding to a water pipe, and each water outlet interface is connected to the inlet of the corresponding water pipe. By providing the water inlet connector, water in the water inlet pipe can flow into each water pipe separately.

[0017] Furthermore, there are two return water pipes, and the mattress is also equipped with return water connectors corresponding to each return water pipe. Each return water connector extends along the width of the mattress, and the two return water connectors are arranged side by side at the second end of the mattress.

[0018] Furthermore, each return water connector is equipped with a first return water interface and a second return water interface. The first return water interface is used to connect to the return water outlet of the corresponding return water pipe. The second return water interfaces are spaced apart along the length of the return water connector and correspond one-to-one with each water pipe on the corresponding side. Each second return water interface is connected to the outlet of the corresponding water pipe, and the number of water pipes connected to each return water connector is approximately equal. By setting two return water pipes and corresponding return water connectors, the water in each water pipe can flow back more quickly, which helps to accelerate the flow speed of water in each water pipe, thereby improving the temperature regulation effect of the mattress.

[0019] Furthermore, the mattress is provided with second mounting channels for accommodating the water inlet connector and each water return connector. By providing these second mounting channels, the water inlet connector and each water return connector can be installed within the mattress, resulting in a compact mattress structure and preventing the water inlet connector and each water return connector from being exposed and affecting the mattress's aesthetic appearance.

[0020] Compared with existing technologies, the advantages of this invention are as follows: The mattress is equipped with water pipes and corresponding limiting structures. In the initial state, the cross-sectional area of ​​each water pipe is A. When the mattress is compressed and deformed, each water pipe deforms along with the mattress until it is limited by the corresponding limiting structure, and in the deformed state, the cross-sectional area of ​​each water pipe is B, where B > A. Thus, in the initial state, when the mattress where a person lies is compressed and deformed, the water pipes in the compressed area deform accordingly, increasing the cross-section of the corresponding water pipe from A to B. This increases the water flow rate, thereby better regulating the temperature of the mattress where the person lies.

[0021] As can be seen, this utility model has a simple structure and can achieve adaptive adjustment of mattress temperature in response to human body weight. The adjustment is convenient and effective. For example, if the water pipe contains cold water, it can lower the temperature of the bed bottom; if the water pipe contains hot water, it can raise the temperature of the mattress.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0030] like Figures 1-6 As shown, a temperature-adjustable mattress system includes a mattress 1 that can deform under pressure. The mattress 1 has water pipes 2 extending along the length of the mattress 1 and spaced apart along its width. The mattress 1 also has corresponding limiting structures 7 for each water pipe 2. Initially, the cross-sectional area of ​​each water pipe 2 is A. When the mattress 1 deforms under pressure, each water pipe 2 deforms along with the mattress 1 until it is limited by the corresponding limiting structure 7, and in the deformed state, the cross-sectional area of ​​each water pipe 2 is B, where B > A.

[0031] In this invention, the mattress 1 is equipped with water pipes 2 and corresponding limiting structures 7. Initially, the cross-sectional area of ​​each water pipe 2 is A. When the mattress 1 is compressed and deformed, each water pipe 2 deforms along with the mattress 1 until it is limited by the corresponding limiting structure 7, and in the deformed state, the cross-sectional area of ​​each water pipe 2 is B, where B > A. Thus, in the initial state, when the mattress 1 where a person lies is compressed and deformed, the water pipes 2 in the compressed area deform accordingly, increasing the cross-section of the corresponding water pipe 2 from A to B. This increases the water flow rate in the water pipes 2, thereby effectively regulating the temperature of the mattress 1 where the person lies. Therefore, this invention has a simple structure, can achieve adaptive temperature regulation of the mattress 1 in response to human body weight, is convenient to adjust, and has a good adjustment effect. For example, if the water in the water pipe 2 is cold, it can lower the temperature of the area under the mattress; if the water in the water pipe 2 is hot, it can raise the temperature of the mattress 1.

[0032] Preferably, in the initial state, the cross-sectional shape of each of the above-mentioned water pipes 2 is an ellipse extending vertically (e.g., Figure 2As shown in the figure, under the deformed state, the cross-sectional shape of each of the above-mentioned water pipes 2 is circular. With the perimeter unchanged, the area of ​​a circle is larger than that of an ellipse. Therefore, the cross-sectional shape of each water pipe 2 can be increased by deforming from an initial elliptical shape to a circle.

[0033] like Figure 2 As shown, the mattress 1 is provided with a first installation channel 111 corresponding to each water pipe 2. Each first installation channel 111 extends along the length of the mattress 1 and allows the corresponding water pipe 2 to be installed along its own length. Each limiting structure 7 includes a limiting plate 71, which extends along the length of the mattress 1 and is installed in the corresponding first installation channel 111 along its own length. Each limiting plate 71 is located below the corresponding water pipe 2. Furthermore, the cross-section of each limiting plate 71 is arc-shaped. In the initial state, the cross-section of each water pipe 2 is a long strip extending vertically. In the deformed state, the lower outer surface of each water pipe 2 is aligned vertically with the inner surface of the corresponding limiting plate 71 along its length. The installation of each water pipe 2 and each limiting structure 7 in the mattress 1 is achieved by setting the first installation channel 111. The cross-section of each limiting plate 71 is arc-shaped. In this way, when the mattress 1 is deformed by pressure and each limiting plate 71 is deformed by pressure, each limiting plate 71 can limit the water pipe 2 and prevent the water pipe 2 from deforming further and becoming a long strip extending in the width direction of the mattress 1.

[0034] Preferably, the cross-section of each of the aforementioned limiting plates 71 is semi-circular, and its size matches the cross-sectional area of ​​the corresponding water pipe 2 in the deformed state. Furthermore, each limiting plate 71 and the corresponding water pipe 2 are vertically aligned. This allows each limiting plate 71 to better limit the corresponding water pipe 2 in the deformed state, and to limit the corresponding water pipe 2 to a circular cross-sectional shape, thereby maximizing the cross-sectional area of ​​each water pipe 2 in the deformed state (a circle has the largest area for the same perimeter), thus improving the temperature regulation effect on the mattress 1.

[0035] Specifically, such as Figure 2 and Figure 3As shown, the mattress 1 includes a first padding layer 1a that comes into contact with the human body and a second padding layer 1b located below the first padding layer 1a. The second padding layer 1b has recessed first mounting grooves 121 corresponding to each water pipe 2. Each first mounting groove 121 extends along the length of the mattress 1 and, together with the first padding layer 1a covering the second padding layer 1b, forms the first mounting channel 111. Each water pipe 2 is fixed to the lower surface of the first padding layer 1a, and each limiting plate 71 is fixed to the inner bottom surface of the corresponding first mounting groove. Initially, the lower end of each water pipe 2 is in contact with the corresponding limiting plate 71. This allows for the construction of each first mounting channel 111 within the mattress 1, facilitating the installation of each water pipe 2 and each limiting plate 71, and ensuring the stable installation of each water pipe 2 and each limiting plate 71. Preferably, each of the above-mentioned water pipes 2 is bonded to the lower surface of the first padding layer 1a along its own length direction, and the lower surface of each limiting plate 71 is bonded to the inner bottom surface of the corresponding first mounting groove 121 along its own length direction, thereby further ensuring the stable installation of each water pipe 2 and each limiting plate 71 in the mattress 1.

[0036] like Figure 3 and Figure 5 As shown, it also includes an inlet pipe 3 and a return pipe 4. The inlet of each water pipe 2 is fluidly connected to the outlet of the inlet pipe 3, and the outlet of each water pipe 2 is fluidly connected to the return outlet of the return pipe 4. This allows the water flow in each water pipe 2 to form a water circulation, facilitating better temperature regulation of the mattress 1. The inlet of the inlet pipe 3 and the outlet of each return pipe 4 are connected to the main unit 8 of the mattress system.

[0037] Furthermore, such as Figure 3 and Figure 5As shown, the first end of the mattress 1 is provided with a water inlet connector 5, which extends along the width of the mattress 1. One side of the water inlet connector 5 is provided with a water inlet interface 51 connected to the water outlet of the water inlet pipe 3, while the other side is provided with water outlet interfaces 52 at intervals along its length, corresponding to each water pipe 2. Each water outlet interface 52 is connected to the water inlet of the corresponding water pipe 2. By providing the water inlet connector 5, water in the water inlet pipe 3 can flow into each water pipe 2. Furthermore, there are two return water pipes 4, and the mattress 1 is also provided with return water connectors 6 corresponding to each return water pipe 4. Each return water connector 6 extends along the width of the mattress 1, and the two return water connectors 6 are arranged side by side in the second end of the mattress 1. Furthermore, each return water connector 6 is equipped with a first return water interface 61 and a second return water interface 62. The first return water interface 61 is used to connect to the return water outlet of the corresponding return water pipe 4. The second return water interfaces 62 are spaced apart along the length of the return water connector 6 and correspond one-to-one with each water pipe 2 on the corresponding side. Each second return water interface 62 is connected to the outlet of the corresponding water pipe 2. The number of water pipes 2 connected to each return water connector 6 is the same (seven in this embodiment). By setting two return water pipes 4 and corresponding return water connectors 6, the water in each water pipe 2 can return more quickly, which helps to accelerate the flow speed of water in each water pipe 2, thereby improving the temperature regulation effect of the mattress 1.

[0038] like Figure 2 As shown, the mattress 1 is provided with a second mounting channel 112 for the water inlet connector 5 to be installed along its own length, and a third mounting channel 113 for each water return connector 6 to be installed along its own length. By setting the second mounting channel 112 and each of the third mounting channels 113, the water inlet connector 5 and each of the water return connectors 6 are installed in the mattress 1, thereby making the structure of the mattress 1 compact and avoiding the water inlet connector 5 and each of the water return connectors 6 being exposed, which would affect the appearance of the mattress 1.

[0039] In this embodiment, specifically, as follows: Figure 5As shown, the inlet ends of the water inlet pipe 3 and each return water pipe 4 extend along the length of the mattress 1 and are arranged side-by-side at the center of the first end of the mattress 1 along the width of the mattress 1. The upper surface of the second padding layer 1b is recessed with third mounting grooves 123 for the three pipes to be inserted. Simultaneously, the first end of the upper surface of the second padding layer 1b is also recessed with a second mounting groove 122 extending along the width of the mattress 1. This second mounting groove 122 is located between each first mounting groove 121 and each third mounting groove 123 and is connected to one end of each first mounting groove 121. Furthermore, the two ends of the second mounting groove 122 extend along the length of the mattress 1 to form fourth mounting grooves 124, and the free ends of each fourth mounting groove 124 extend towards the width of the mattress 1 to form fifth mounting grooves 125. Each fifth mounting groove 125 corresponds one-to-one with each return water connector 6, and each return water connector 6 is installed in its corresponding fifth mounting groove 125 along its own length.

[0040] Furthermore, each of the third mounting grooves 123 communicates with the aforementioned second mounting groove 122. The aforementioned water inlet connector 5 is installed in the second mounting groove 122 along its own length direction. Each return water pipe 4 is installed sequentially along the corresponding third mounting groove 123, the corresponding position of the second mounting groove 122, and the corresponding side of the fourth mounting groove 124. Additionally, the first pad layer 1a covers the upper surface of the second pad layer 1b, forming the aforementioned second mounting channel 112 with the second mounting groove 122, and simultaneously forming second mounting channels 113 with each of the fifth mounting grooves 125, as shown below. Figure 6 As shown.

[0041] The term "fluid connectivity" as used in this utility model refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
