These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0045] like Figures 1 to 4As shown, the utility model provides a body supporting component, which includes a sac 1, and one of a plurality of punching holes 11 and a plurality of protrusions 120 is arranged on the sac 1. A connecting flow channel 12 for water circulation is formed between two adjacent punching holes 11 or two adjacent protrusions 120. The sac 1 also has an inlet channel 13 and a return channel 14; the connecting flow channel 12 includes a first flow channel 121 and a second flow channel 122, the first flow channel 121 is connected to the water inlet channel 13, the first flow channel 121 is connected to the second flow channel 122, and the second flow channel 122 is connected to the return channel 14, and the number of the first flow channels 121 is greater than the number of the second flow channels 122. In this embodiment, a plurality of punchings 11 or protrusions 120 are arranged on the sac body 1, and the punchings 11 or protrusions 120 can be matched with corresponding protrusions 120 or punchings 11 to achieve a smooth installation of the sac body 1, so that the body support component can be flatly attached to the human body, thereby improving the comfort of the user; water flows in the sac body 1 through the water inlet channel 13, the first flow channel 121, the second flow channel 122 and the return channel 14 in sequence. Since the number of the first flow channels 121 is greater than the second flow channels 122, the water entering the sac body 1 can flow through a larger area of ​​the sac body 1, thereby ensuring the cooling or warming effect of the sac body 1 on the human body. Specifically, the bladder body 1 is a flexible water bag made of latex or plastic, and has a rectangular appearance. A plurality of rectangular punching holes 11 are evenly spaced on the water bag, so that the water bag can be matched and installed with the load-bearing core 100 having a protrusion 120; the edges of the punching holes 11 are closed to allow water to flow between two adjacent punching holes 11 and between the punching holes 11 and the edges of the water bag; the water inlet channel 13 is used to flow hot water or cold water into the bladder body 1, thereby providing a warming or cooling effect for the user.

[0046] Further, if Figure 4 As shown, the connecting flow channel 12 also includes a third flow channel 123, which is vertically connected to the first flow channel 121 and the second flow channel 122, respectively. The first flow channel 121, the second flow channel 122, and the third flow channel 123 are all of the same width. In this embodiment, the punching holes 11 on the cold supply end 1 are distributed in an array, forming the first flow channel 121, the second flow channel 122, and the third flow channel 123 between the punching holes 11. The first flow channel 121 and the second flow channel 122 are respectively vertically connected to the third flow channel 123, thereby forming a cross-shaped connecting flow channel 12. Since the first flow channel 121, the second flow channel 122, and the third flow channel 123 are of the same width, it can ensure that water flows at a uniform speed in the connecting flow channel 12, thereby further improving the uniformity of temperature across the bladder 1.

[0047] Specifically, if Figure 4 As shown, the third flow channel 123 is partially communicated with the second flow channel 122. In this embodiment, the first flow channel 121 is communicated with the second flow channel 122 through a portion of the third flow channel 123.

[0048] Further, if Figure 2 and Figure 3 As shown, the body support component also includes a load-bearing core 100, which has a mounting groove 110 for accommodating the bladder 1. The surface of the bladder 1 opposite the mounting groove 110 is an attachment surface, which is used to abut against the human body. The mounting groove 110 is provided with another type of material corresponding to the multiple punched holes 11 or multiple protrusions 120 on the bladder 1. The protrusions 120 are locked in the punched holes 11, and the attachment surface and the surface of the load-bearing core 100 are located in the same plane. In this embodiment, the bladder 1 is arranged on the load-bearing core 100. Since the load-bearing core 100 has the mounting groove 110 for accommodating the bladder 1, and the bladder 1 can be assembled with the load-bearing core 100 through the cooperation of the punched holes 11 and the protrusions 120, the attachment surface of the bladder 1 is located in the same plane as the surface of the load-bearing core 100, ensuring the flatness of the surface of the load-bearing core 100, thereby improving the comfort of the user.

[0049] like Figure 1 and Figure 3 As shown, this embodiment also provides a circulating water flow system, which includes the above-mentioned body support component and a circulation assembly 2. The circulation assembly 2 includes a circulating water pipe 21 and a driving member 22. The driving member 22 is disposed on the circulating water pipe 21, and the two ends of the circulating water pipe 21 are respectively connected to the water inlet channel 13 and the water return channel 14. The circulating water pipe 21 is provided with a temperature control assembly 3, which is used to adjust the temperature of the water in the circulating water pipe 21. The driving member 22 is used to drive the water to flow between the circulating water pipe 21 and the bladder 1. In this embodiment, because the circulating water pipe 21 is provided with the temperature control assembly 3, which is used to adjust the temperature of the water in the circulating water pipe 21, and the driving member 22 is capable of driving the water to flow between the circulating water pipe 21 and the bladder 1, the driving member 22 drives the water, which has been cooled or heated, to circulate continuously to the bladder 1, thereby realizing the body support component's function of regulating the body temperature. Specifically, the driving member 22 is a water pump.

[0050] Further, if Figure 1 、 Figure 3 as well as Figure 6As shown, the circulating water flow system also includes a liquid storage box 4, and the circulating water pipe 21 includes a water supply pipe 211 and a return water pipe 212. The liquid storage box 4 has an inner cavity, and the two ends of the water supply pipe 211 are respectively connected to the inner cavity and the water inlet channel 13, and the two ends of the return water pipe 212 are respectively connected to the inner cavity and the return water channel 14. The inner diameter of the inner cavity is larger than the inner diameters of the water supply pipe 211 and the return water pipe 212. In this embodiment, the water supply pipe 211 is used to transport water to the water inlet channel 13. Since the return pipe 212 and the water supply pipe 211 are connected through the inner cavity of the liquid storage box 4, when water enters the inner cavity through the return pipe 212, the water pressure will be released due to the increase in cross-sectional area, thereby alleviating the noise caused by the impact of the water flow on the pipe wall due to excessive speed; at the same time, the inner cavity will temporarily store the water to accommodate more water, thereby increasing the weight and stabilizing the pressure of the entire circulation component 2, preventing the circulation component 2 from shaking during operation, and thereby reducing the vibration noise of the circulating water system.

[0051] Specifically, if Figure 3 and Figure 5 As shown, the temperature control assembly 3 includes a semiconductor cooling element 31 and a heat exchanger 32. The semiconductor cooling element 31 has a first and a second opposing surface. One of the first and second surfaces is positioned against the liquid reservoir 4. The first surface can absorb or release heat, while the second surface, opposite the first surface, can release or absorb heat. The heat exchanger 32 is positioned on the other surface of the semiconductor cooling element 31, away from the liquid reservoir 4. In this embodiment, the semiconductor cooling element 31 is a commonly used temperature control element in the art. It is externally connected to a power source and, when powered, can cool or heat the device through the Peltier effect. Specifically, when the semiconductor cooling element 31 is in cooling mode, the temperature of the first surface of the semiconductor cooling element 31 decreases, while the temperature of the second surface increases. When the polarity of the current flowing into the semiconductor cooling element 31 is changed, the semiconductor cooling element 31 switches to heating mode, in which the temperature of the first surface increases and the temperature of the second surface decreases. Therefore, the user can switch the usage mode of the semiconductor cooling element 31 according to their needs. The heat exchanger 32 is a fin-type heat exchanger commonly used in the art, which can accelerate the heat exchange between the semiconductor cooling plate 31 and the external environment to ensure that the semiconductor cooling plate 31 can continuously and efficiently achieve cooling or heating.

[0052] Specifically, if Figure 3 and Figure 5 As shown, the temperature control assembly 3 further includes a fan 33, which is disposed directly opposite the heat exchanger 32. In this embodiment, the fan 33 can accelerate the air flow around the heat exchanger 32, thereby promoting the heat exchange rate between the semiconductor cooling plate 31 and the surrounding environment, thereby improving the cooling or heating effect of the semiconductor cooling plate 31.

[0053] Specifically, if Figure 1 and Figure 3As shown, the circulating water flow system further includes a temporary storage body 5 disposed on the circulating water pipe 21. The temporary storage body 5 has a temporary storage cavity that is in communication with the circulating water pipe 21 and is used to accommodate water in the circulating water pipe 21. In this embodiment, two temporary storage bodies 5 are provided, one on the water supply pipe 211 and the other on the water return pipe 212. Specifically, the temporary storage body 5 is a hollow tubular structure with an inner diameter larger than that of the water supply pipe 211 and the water return pipe 212. Taking the temporary storage body 5 of the water supply pipe 211 as an example, its temporary storage cavity can accommodate low-temperature or high-temperature water flowing in the water supply pipe 211, thereby increasing the weight of the local area of ​​the water supply pipe 211, thereby cushioning and suppressing the vibration generated by the driving member 22 during operation, thereby reducing the noise of the circulation assembly 2.

[0054] Specifically, if Figure 2 、 Figure 3 as well as Figure 5 As shown, the circulating water flow system also includes a housing 6, which includes an upper shell 61 and a lower shell 62.

The upper shell 61 is covered on the driving member 22, the temperature regulating component 3 and the temporary storage body 5, and the upper shell 61 and the lower shell 62 are detachably connected. In this embodiment, Figure 5 The upper shell 61 is concealed to facilitate viewing of the internal structure of the housing 6; the housing 6 protects and reduces noise for the driver 22, temperature control assembly 3, and temporary storage body 5 housed therein. Specifically, the driver 22, liquid reservoir 4, temperature control assembly 3, and temporary storage body 5 are all mounted on the lower shell 62, which are bolted together. A bracket with silicone sealant is provided on the lower shell 62, to which the driver 22 is affixed. The silicone sealant on the bracket isolates the driver 22 from vibration. The upper shell 61 is provided with through-holes for the water supply pipe 211 and the return pipe 212 to pass through. The water supply pipe 211 and the return pipe 212 pass through the through-holes and connect to the capsule 1.

The first sound-absorbing layer 231 is first wrapped around the driving member 22 and then inserted into the first sleeve 232. The second sound-absorbing layer 233 is then wrapped around the outside of the first sleeve 232 and then inserted into the second sleeve 234. Finally, end caps 235 are installed at both ends of the second sleeve 234 to seal it.

[0056] like Figure 2As shown, this embodiment further provides a sleeping appliance, which includes the above-mentioned circulating water system and a cover 200, and the cover 200 is mounted on the body supporting component. In this embodiment, the bladder 1 is arranged in the installation groove 110 of the load-bearing core 100, thereby forming a complete body support component; specifically, the outer shell 200 includes a core sleeve 210 and a detachable cover 220, wherein the core sleeve 210 is sleeved on the load-bearing core 100 and closed with a zipper, thereby wrapping the bladder 1 and the load-bearing core 100 inside; the detachable cover 220 is sleeved on the core sleeve 210; both the core sleeve 210 and the load-bearing core 100 are provided with through holes for the water supply pipe 211 and the return pipe 212 to pass through, and the outer shell 6 is placed outside the outer shell 200.
