Description

Technical Field

[0001] This invention relates to the field of mattress technology, specifically to a water-heatable mattress. Background Technology

[0002] Mattresses are a common household necessity, placed on beds to provide comfort. In cold winter months, low temperatures can cause chills, and heating features can alleviate this discomfort. Waterbeds utilize the fluid flow within a water bladder to deform freely according to body pressure, and heating plates regulate the temperature of the fluid. In essence, waterbeds distribute body pressure and, due to improved blood circulation and other general uses, have become a popular medical treatment. However, conventional heated waterbeds have several drawbacks. The fluid's free flow caused by body pressure can create unstable waves, negatively impacting the user experience. Furthermore, typical heated waterbeds are prone to heat buildup, where the water near the heating element is hotter than at the top, resulting in uneven heating and a slower temperature rise at the top. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this invention is to provide a water-heatable mattress that has the advantages of reducing internal vibration, making the internal liquid temperature distribution more uniform, and improving the internal liquid heat diffusion efficiency.

[0004] This invention is achieved using the following technical solution: A water mattress capable of being heated includes: a flexible outer shell, a flexible pad, an adaptive cushioning unit assembly, a flexible diaphragm, and a high-efficiency heating block; The flexible shell has a certain degree of deformation and thermal conductivity. It can compress the liquid inside when subjected to pressure from the human body, while providing the user with softness feedback. A temperature sensor (not shown) is installed inside the flexible shell, which can provide feedback on the internal temperature of the mattress. The flexible pad and the adaptive cushioning unit group together form the mattress core. The flexible pad and the adaptive cushioning unit group are connected to form a confluence cavity in the middle. When the upper surface of the mattress is squeezed by the user, the flexible pad deforms accordingly. Because it sinks down, it has a sense of resistance and can provide a softer experience. The confluence cavity has outlets distributed around it. The confluence cavity collects the heated liquid diffused by the adaptive cushioning unit group and then delivers the heated liquid to the surrounding area through the outlets, so that the liquid temperature inside the upper part of the mattress is evenly distributed. The flexible diaphragm is connected to both the flexible shell and the adaptive buffer unit group. When the flexible diaphragm is not subjected to force, it is in a relaxed state and has a certain deformation margin and a certain elasticity. The flexible diaphragm and the adaptive buffer unit group together divide the interior of the mattress into two chambers: a steady flow chamber and a hot flow chamber. This allows the liquid in the upper and lower chambers to exchange only through the adaptive buffer unit group, making the liquid heat diffusion more regular. The high-efficiency heating block is installed at the bottom of the flexible shell, with the installation position located at the center of the bottom of the mattress. The grooves between its wing-like structures extend in a direction parallel to the length of the mattress. The high-efficiency heating block is connected to a controller and a power switch (not shown). When the switch is turned on, the liquid is heated. When the liquid temperature reaches the threshold set by the controller, the heating block reduces the heating power to maintain the mattress temperature within the set temperature range. The flexible shell is provided with an inlet and an outlet for the connection of external power equipment, such as a liquid pump. Fluid flows in from the inlet and flows out from the outlet, and the fluid circulates. The inlet is connected to the hot flow chamber, and the outlet is connected to the flow stabilization chamber.

[0005] The adaptive buffer unit group consists of several adaptive buffer units arranged together. The adaptive buffer unit includes a lower substrate, a flow-guiding plate, an upper cover plate, and a damping wall. The staggered distribution structure of the flow-guiding plate and the upper cover plate can fully diffuse the heat flow and make the temperature diffusion more uniform. Specifically, a heat flow inlet and fine holes are provided on the lower substrate. The heated heat flow is transported up from the lower cavity and enters the adaptive buffer unit group through the heat flow inlet and fine holes. The heat flow inlet guides the transported heat flow, allowing the heat flow to fully enter the adaptive buffer unit. The fine holes are distributed around the heat flow inlet, which can generate a certain damping effect while serving as the heat flow inlet. When the bed core structure is lowered by external force, the damping effect can generate a certain resistance to slow down the descent rate of the bed core and produce a soft feeling. Specifically, drainage holes are formed on the drainage hole plate, and damping holes are formed on the upper cover plate. The drainage holes are arranged in an array, and the damping holes are arranged in a staggered array. When the heat flow passes through the drainage hole group, the heat flow is uniformly diffused. When the heat flow passes through the damping hole group, the heat flow is further diffused, making the mixing of the heat flow and the upper cold flow more uniform. The drainage holes are arranged in an array at the center of the drainage plate, and the damping holes are arranged in an array in a ring around the periphery of the upper cover plate. The maximum distribution diameter of the drainage holes is φ1, and the minimum distribution diameter of the damping holes is φ2, and φ2>φ1. Specifically, the outer damping wall has through holes. When a user lies on the mattress, the liquid inside the mattress is compressed and disturbed. At this time, the damping effect of the side through holes can suppress the horizontal wave effect generated by the liquid inside the mattress, allowing the liquid inside the mattress to return to a stable state more quickly and improving the stability of the mattress. On the other hand, the through holes can also act as drainage holes, allowing some heat flow to diffuse to the side cavity of the flow stabilizing chamber, further improving the heat exchange efficiency of the liquid. When the user lies on the mattress, the mattress core is pressed down. At this time, the drainage holes in the adaptive buffer unit can act as damping holes to dampen the liquid below, producing a certain buffering effect and suppressing the vertical disturbance of the liquid. In some specific embodiments of the present invention, the flexible pad is connected to the adaptive buffer unit group to form a manifold cavity. The manifold cavity has a manifold cavity outlet around its perimeter. A partition is installed inside the lower part of the flexible shell. The high-efficiency heating block is installed at the bottom of the flexible shell and located below the partition, with a certain distance between it and the partition. The partition is a rigid frame structure. The high-efficiency heating block is displaced within the frame structure of the partition. This can ensure the heating space of the high-efficiency heating block and prevent it from being contacted, thereby generating heat accumulation.

[0006] In particular, because a confluence cavity is provided between the flexible pad and the adaptive cushioning unit group, the flexible pad has less resistance when it sinks, giving the user lying on the mattress a soft feeling; Specifically, the middle part of the partition has a downwardly recessed section that forms a flow-gathering cavity. The flow-gathering cavity is connected to the first and second flow-gathering channels on both sides, forming a fluid heating cavity between the partition and the high-efficiency heating block. The specific flow path of the fluid is as follows: after being pumped by the water pump, the liquid enters from the inlet, first entering the front end of the hot flow cavity, then reaching the high-efficiency heating block for fluid heating, then entering the rear end of the hot flow cavity, flowing through the rear end of the hot flow cavity into the first and second flow-gathering channels, and then entering the flow-gathering cavity again. The flow-gathering cavity, through the bed core, guides the fluid into the stabilizing cavity (the flow-gathering cavity is connected to the stabilizing cavity through the bed core), where heat diffusion occurs, and finally, the fluid flows out through the outlet. In some specific embodiments of the present invention, a high-efficiency heating block is also included, which includes heating fins and a heating groove. The high-efficiency heating block increases the contact area with the liquid by extending the heating fins to improve heating efficiency. Furthermore, another structural form further increases the contact area with the liquid by adding side protrusions to the heating fins. The protruding part includes, but is not limited to, the rectangular shape shown in the figure, but can also be any structure that increases the contact area, such as hemispherical or arc-shaped. In some specific embodiments of the present invention, the top cover of the adaptive buffer unit is made of a flexible material, while the drainage plate is made of a rigid material (such as a plastic plate, a metal plate, etc., with no deformation or minimal deformation). When the liquid pressure through the damping holes on the top cover suddenly increases (e.g., a person suddenly sits on the bed), the top cover will deform due to the sudden increase in pressure difference inside and outside the adaptive buffer unit, thereby shifting towards the drainage plate. At this time, the liquid flow through the drainage holes on the drainage plate will decrease, and the resistance provided by the adaptive buffer unit will increase, thereby improving the cushioning capacity of the mattress, realizing adaptive damping adjustment, and reducing liquid disturbance in the vertical direction inside the mattress.

[0007] Furthermore, the shape of the adaptive buffer unit includes, but is not limited to, the cuboid shape shown in the figure, but can also be a regular internal cavity structure with layering, such as a cylinder or a frustum. Furthermore, the drainage hole plate has a protrusion at its center, which prevents the top cover from completely covering the drainage hole, further improving the reliability of the mattress.

[0008] In some specific embodiments of the present invention, the material used for the bed core is a flexible material with a density slightly less than or equal to that of the heated liquid. The bed core is suspended inside the mattress under the buoyancy of the liquid. The mattress is equipped with a power switch and control elements, which are not shown in the figure. According to some embodiments of the present invention, the partition is recessed in the middle to form a flow-gathering cavity, which collects the heated liquid and transports it to the inside of the bed core.

[0009] In summary, compared with the prior art, the present invention has the following beneficial effects: This invention provides a heatable water mattress that, when heated liquid is transported from the lower part of the mattress to the upper part, allows the heat flow to be evenly diffused around the upper chamber of the mattress, thereby ensuring a uniform temperature distribution inside the mattress and preventing localized overheating, thus improving the heat diffusion efficiency of the liquid inside the mattress. On the other hand, through the through holes on the damping wall of the adaptive cushioning unit and the drainage holes on the inner side, a cushioning effect can be provided when the user lies on the mattress, which can suppress the wave action inside the mattress and provide the user with softness feedback.

[0014] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0015] Reference Figure 1 In some specific embodiments of the present invention, a heatable water mattress includes: a flexible outer shell 1, a flexible pad 2, an adaptive cushioning unit group 3, a flexible diaphragm 4, and a high-efficiency heating block 5. The flexible shell 1 has a certain deformation capacity and thermal conductivity. It can squeeze the liquid inside it when subjected to pressure from the human body, and at the same time provide the user with softness feedback. A temperature sensor (not shown) is installed inside the flexible shell, which can provide feedback on the internal temperature value of the mattress. Reference Figure 2 The flexible pad 2 and the adaptive cushioning unit group 3 together constitute the bed core. The flexible pad 2 and the adaptive cushioning unit group 3 are connected to form a confluence cavity 22 in the middle. When the upper surface of the mattress is squeezed by the user, the flexible pad deforms as it is squeezed. Because it sinks down, it has a sense of resistance and can provide a softer experience. The confluence cavity 22 has confluence cavity outlets 21 distributed around it. The confluence cavity 22 collects the heated liquid that has been diffused through the adaptive cushioning unit group 3 and then delivers the heated liquid to the surrounding area through the confluence cavity outlets 21, so that the liquid temperature distribution inside the mattress is uniform. The flexible diaphragm 4 is connected to both the flexible shell 1 and the adaptive buffer unit group 3. When the flexible diaphragm 4 is not subjected to force, it is in a relaxed state and has a certain deformation margin and a certain elasticity. The flexible diaphragm 4 and the adaptive buffer unit group 3 together divide the interior of the mattress into two chambers: a steady flow chamber 14 and a hot flow chamber 13. This allows the liquid in the upper and lower chambers to exchange only through the adaptive buffer unit group 3, making the liquid heat diffusion more regular. The high-efficiency heating block 5 is installed at the bottom of the flexible shell 1, and the installation position is located at the center of the bottom of the mattress. The groove between its wing-shaped structures extends in a direction parallel to the length of the mattress. The high-efficiency heating block 5 is connected to a controller and a power switch (not shown). When the switch is turned on, the liquid is heated. When the liquid temperature reaches the threshold set by the controller, the heating block reduces the heating power to maintain the mattress temperature within the set temperature range. The flexible shell 1 is provided with an inlet 12 and an outlet 11 for the connection of external power equipment, such as a liquid pump. Fluid flows in from the inlet 12 and flows out from the outlet 11, and the fluid circulates. The inlet 12 is connected to the hot flow chamber 13, and the outlet 11 is connected to the flow stabilizing chamber 14.

[0016] The adaptive buffer unit group 3 is composed of several adaptive buffer units 30 arranged together. The adaptive buffer unit 30 includes a lower substrate 31, a flow-draining plate 32, an upper cover plate 33, and a damping wall 34. The staggered distribution structure of the flow-draining plate 32 and the upper cover plate 33 can fully diffuse the heat flow and make the temperature diffusion more uniform. Specifically, a heat flow inlet 312 and a fine hole 311 are provided on the lower substrate 31. The heated heat flow is transported up from the lower cavity and enters the adaptive buffer unit group 3 through the heat flow inlet 312 and the fine hole 311. The heat flow inlet 312 guides the transported heat flow so that the heat flow can fully enter the adaptive buffer unit 30. The fine hole 311 is distributed around the heat flow inlet 312. While serving as a heat flow inlet, it can also generate a certain damping effect. When the bed core structure is lowered by external force, the damping effect can generate a certain resistance to slow down the descent rate of the bed core and produce a soft feeling. Specifically, a flow-draining hole 321 is formed on the flow-draining plate 32, and a damping hole 331 is formed on the upper cover plate 33. The flow-draining holes 321 are arranged in an array, and the damping holes 331 are arranged in a staggered array with the flow-draining holes 321. When the heat flow passes through the flow-draining hole array, the heat flow is uniformly diffused. When the heat flow passes through the damping hole array, the heat flow is further diffused, making the mixing of the heat flow and the upper cold flow more uniform. The flow-draining holes 321 are arranged in an array at the center of the flow-draining plate 32, and the damping holes 331 are arranged in an array in a ring around the periphery of the upper cover plate 33. The maximum distribution diameter of the flow-draining holes 321 is φ1, and the minimum distribution diameter of the damping holes 331 is φ2, and φ2>φ1. Specifically, the outer damping wall 34 has through holes 301. When a user lies on the mattress, the liquid inside the mattress is compressed and disturbed. At this time, the damping effect of the side through holes 301 can suppress the horizontal wave effect generated by the liquid inside the mattress, allowing the liquid inside the mattress to return to a stable state more quickly and improving the stability of the mattress. On the other hand, the through holes 301 can also act as drainage holes, allowing some heat flow to diffuse to the side cavity of the flow stabilizing cavity 14, further improving the heat exchange efficiency of the liquid. When a user lies on the mattress, the mattress core is pressed down. At this time, the drainage holes in the adaptive buffer unit 30 can act as damping holes to dampen the liquid below, producing a certain buffering effect and suppressing the vertical disturbance of the liquid. Reference Figure 3 as well as Figure 4In some specific embodiments of the present invention, the flexible pad 2 is connected to the adaptive buffer unit group 3 to form a manifold 22. The manifold 22 has a manifold outlet 21 around its perimeter. A partition 15 is installed inside the lower part of the flexible shell 1. The high-efficiency heating block 5 is installed at the bottom of the flexible shell 1 and located below the partition 15, with a certain distance between it and the partition 15. The partition 15 is a rigid frame structure. The high-efficiency heating block 5 is displaced within the frame structure of the partition 15. This can ensure the heating space of the high-efficiency heating block 5 and prevent it from being contacted and thus generating heat accumulation.

[0017] In particular, because a manifold 22 is provided between the flexible pad 2 and the adaptive cushioning unit group 3, the flexible pad 2 has less resistance when it sinks, giving the user lying on the mattress a soft feeling. Specifically, the middle part of the partition 15 has a downwardly recessed portion that forms a flow-gathering cavity 135. The two sides of the flow-gathering cavity 135 are connected to the first flow-gathering channel 133 and the second flow-gathering channel 134, forming a fluid heating cavity between the partition 15 and the high-efficiency heating block 5. The specific flow path of the fluid is as follows: after being pumped by the water pump, the liquid enters from the inlet 12, first entering the front end 131 of the hot flow cavity, then reaching the high-efficiency heating block 5 for fluid heating, and then entering the rear end 132 of the hot flow cavity. Through the rear end 132 of the hot flow cavity, it flows into the first flow-gathering channel 133 and the second flow-gathering channel 134, and then enters the flow-gathering cavity 135. The flow-gathering cavity 135 passes the fluid into the stabilizing cavity 14 through the bed core (the flow-gathering cavity 135 is connected to the stabilizing cavity 14 through the bed core), where heat diffusion occurs, and finally it flows out through the outlet 11. Reference Figure 5 as well as Figure 6 In some specific embodiments of the present invention, a high-efficiency heating block 5 is also included. The high-efficiency heating block 5 includes heating fins 51 and heating grooves 52. The high-efficiency heating block 5 increases the contact area with the liquid by extending the heating fins 51 to improve the heating efficiency. Furthermore, Figure 6 for Figure 5 Another structural form is to further increase the contact area with the liquid by adding side protrusions to the heating fins 51. The protrusions include, but are not limited to, the rectangular shape shown in the figure, but can also be any structure that increases the contact area, such as hemispherical or arc-shaped. Reference Figure 7 as well as Figure 8In some specific embodiments of the present invention, the upper cover plate 33 of the adaptive buffer unit 30 is made of a flexible material, while the drainage hole plate 32 is made of a rigid material (such as a plastic plate, metal plate, etc., with no deformation or minimal deformation). When the liquid pressure through the damping hole 331 on the upper cover plate 33 suddenly increases (e.g., a person suddenly sits on the bed), the upper cover plate 33 will deform due to the sudden increase in pressure difference inside and outside the adaptive buffer unit 30, thereby shifting towards the drainage hole plate 32. At this time, the liquid flow rate through the drainage hole 321 on the drainage hole plate 32 will decrease, and the resistance provided by the adaptive buffer unit 30 will increase, thereby improving the cushioning capacity of the mattress, realizing adaptive damping adjustment, and reducing liquid disturbance in the vertical direction inside the mattress.

[0018] Reference Figure 10 In some embodiments of the present invention, simulation tests were conducted on the heated water mattress. Figure 10 According to the pressure distribution table, the areas closer to red are high-pressure zones, and those closer to blue are low-pressure zones. To improve simulation efficiency, a pressure of 400 Pa is applied to the inlet of the adaptive buffer unit. Figure 10 The results show that the fluid in high-pressure zone 61 becomes the fluid in low-pressure zone 63 after being damped by the adaptive buffer unit, and the fluid pressure is significantly reduced (without considering the influence of the fluid's own gravity). According to the results shown in the figure, the fluid pressure can be effectively reduced by the adaptive buffer unit, thereby improving the stability of the liquid environment inside the mattress.

[0019] Furthermore, the shape of the adaptive buffer unit 30 includes, but is not limited to, the cuboid shape shown in the figure, but can also be a regular internal cavity layered structure such as a cylinder or a frustum. Furthermore, such as Figure 9 As shown, the drainage hole plate 32 has a protrusion 322 at its center, which can prevent the top cover plate 33 from completely covering the drainage hole 321, further improving the reliability of the mattress.

[0020] In some specific embodiments of the present invention, the material used for the mattress core is a flexible material with a density slightly less than or equal to that of the heated liquid; the mattress is equipped with an external power switch and control components, which are not shown in the figures. Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
