[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1 Embodiment 1 of the present invention provides a constant temperature seat cushion with far-infrared heating function. Please refer to [link / reference]. Figures 1-3 As shown, it includes: a seat cushion body 1, the seat cushion body 1 having a liquid filling cavity 101 and a sealing cavity 102 inside, the liquid filling cavity 101 being filled with a liquid medium, and the sealing cavity 102 having a receiving cavity 103 on the side near the liquid filling cavity 101, the receiving cavity 103 and the liquid filling cavity 101 being able to transfer heat; a heating component 2 being disposed in the receiving cavity 103, a temperature measuring element 3 being disposed on one side of the heating component 2, the heating component 2 and the temperature measuring element 3 being electrically connected to a terminal connector 6 via wire 1 4 and wire 2 5 respectively, and the terminal connector 6 being electrically connected to an intelligent thermostat 8 via wire 3 7.

[0022] In this first embodiment, the liquid filling cavity 101 is used to fill a liquid medium, which can be water or an oily medium, preferably water. The receiving cavity 103 is an independent cavity set inside the encapsulation cavity 102. The heating component 2, the temperature measuring element 3, and the terminal connector 6 are all encapsulated in the receiving cavity 103. The heating component 2 can generate heat and emit far-infrared rays when heating. The temperature measuring element 3 is used to measure the temperature. The heat generated by the heating component 2 can be transferred to the liquid filling cavity 101 and heat the water. This satisfies the need to heat the liquid medium and isolates the heating component 2 from the liquid medium to be heated, ensuring safety during use. At the same time, the physical property of water's large specific heat capacity can be utilized to play a dual role of heat storage and auxiliary heat dissipation, achieving the purpose of constant temperature regulation. The ability of liquid to deform freely can increase the force-bearing area of ​​the user's contact surface, reduce the pressure at the contact point, and minimize the closure of capillaries, thereby preventing the formation of pressure sores.

[0023] Using this design, the cushion of the present invention uses liquid as filling material, is heated by a heating component and emits far-infrared rays, which can produce a physiotherapy effect on the human body. The cushion is soft and comfortable, and by increasing the pressure area on the buttocks, it can reduce the pressure at the contact points. For people who sit in the office for long periods of time, drive long distances, or use wheelchairs, it can improve microcirculation and eliminate fatigue from prolonged sitting. Combined with the physiotherapy effect of far-infrared rays, it can further improve the microcirculation of the user's lower limbs and whole body, increase human vitality, reduce fatigue caused by prolonged sitting, and has an auxiliary therapeutic effect on improving cold limbs, varicose veins, hemorrhoids, pressure sores, and lower back and leg pain. Long-term use can improve human immunity.

[0024] This invention provides comfort for use in all four seasons. It can solve the problems of poor microcirculation and cold lower limbs caused by prolonged sitting in spring, autumn and winter. In summer, it can also keep the buttocks dry and comfortable by controlling the temperature with liquid and dispersing heat and moisture, thus solving the problem of dampness and heat. It has a good chronic physiotherapy effect for users who sit for long periods of time and can play a role in "passive health care".

[0025] In a further optimized design, multiple spacer plates 9 are arranged in parallel inside the liquid filling cavity 101, with the upper and lower ends of the spacer plates 9 connected to the top and bottom walls of the liquid filling cavity 101, respectively.

[0026] In this embodiment, the seat cushion 1 includes a first connecting piece 1-1, a second connecting piece 1-2, a third connecting piece 1-3, and a fourth connecting piece 1-4. The first connecting piece 1-1 and the second connecting piece 1-2 are pressed and fixed around their perimeters to form a liquid filling cavity 101. The third connecting piece 1-3 and the second connecting piece 1-2 are pressed and fixed around their perimeters to form an encapsulation cavity 102. The fourth connecting piece 1-4 and the second connecting piece 1-2 are pressed and fixed around their perimeters to form an accommodating cavity 103. A connecting spacer 9 is disposed between the first connecting piece 1-1 and the second connecting piece 1-2. The upper and lower ends of the connecting spacer 9 are pressed and fixed to the first connecting piece 1-1 and the second connecting piece 1-2, respectively. Arc-shaped grooves 901 are provided on both sides of the connecting spacer 9. The seat cushion 1 and the connecting spacer 9 are both made of TPU material with a certain degree of elasticity.

[0027] To further optimize the design, multiple spaced notches 902 are provided on the upper and lower sides of the connecting partition 9. These notches 902 create channels for liquid to pass through, facilitating liquid flow.

[0028] In a further optimized design, the heating assembly 2 includes a heating element 21, which is electrically connected to the terminal connector 6 via a wire 4. The heating element 21 has a heat-conducting sheet 22 on the side near the liquid filling cavity 101 and a heat-insulating sheet 23 on the side away from the liquid filling cavity 101.

[0029] In this first embodiment, the heating element 21 is configured as either a PTC graphene heating element 21 or a non-PTC graphene heating element 21. When heated, it can emit far-infrared rays, thereby achieving a physiotherapy effect on the human body. The heat-conducting element 22 can be configured as a graphene film or synthetic graphite paper, which is attached and fixed to the front side of the heat insulation element 23 as a heat-conducting layer to quickly transfer the heat generated by the heating element 21 to the second connecting piece 1-2. The heat is then transferred to the liquid medium in the liquid filling cavity 101 through the second connecting piece 1-2. The heat insulation element 23 can be configured as a rubber gasket, which can provide a certain heat insulation effect. Of course, the heat insulation element 23 can also be configured as a flexible layer formed by curing heat insulation slurry. This flexible layer can be directly coated on the back side of the heating element 21 as a heat insulation layer, which is beneficial to the integrated design and thinness of the heating component 2.

[0030] It is worth noting that when the heating element 21 is set to a non-PTC graphene heating element 21, a temperature switch needs to be connected in series on the wire 4 between the heating element 21 and the terminal connector 6 to avoid damage to the liquid filling cavity 101 due to continuous overheating.

[0031] Further optimization of the design: the wire 3 7 is arranged in an L-shape, with its horizontal end electrically connected to the terminal connector 6, and its vertical end extending through to the outside of the encapsulation cavity 102 and electrically connected to the intelligent temperature controller 8.

[0032] In this first embodiment, the intelligent temperature controller 8 is set as a wide voltage intelligent temperature control power supply, and the voltage range can be AC ​​85~220V-50 / 60Hz or 24V DC; at the same time, it adopts a three-prong grounding design, has an anti-electromagnetic radiation function, and can also adjust the operating temperature in real time.

[0033] In a further optimized design, the portion of wire 37 located inside the encapsulation cavity 102 is connected to the inner wall of the encapsulation cavity 102 via multiple spaced tail clips.

[0034] In this first embodiment, multiple tail clips are used to fix the wire 7. Combined with the L-shaped arrangement of the wire 7, its tensile strength can be improved, ensuring the stability of the connection between the wire 7 and the terminal connector 6.

[0035] To further optimize the design, the seat cushion bladder 1 is equipped with an openable and closable liquid injection port, which is connected to the liquid filling cavity 101. The liquid injection port is located at the edge of the first connecting piece 1-1; liquid medium can be added to the liquid filling cavity 101 through the injection port, and the liquid can be sealed when the injection port is closed.

[0036] It should be noted that, during the encapsulation of the accommodating cavity 103 of the present invention, if... Figure 3 As shown, the fourth connecting piece 1-4 and the second connecting piece 1-2 are first pressed together at points A, B, and C to form a pocket-shaped structure. Then, the heating component 2 is placed in the pocket-shaped structure in sequence. After that, a short blade is pressed together at point D to limit and fix the heating component 2. Then, the temperature measuring element 3 is placed in the area above point D, and the probe of the temperature measuring element 3 is attached to the second connecting piece 1-2. Then, the terminal connector 6 is fixed to one side of the temperature measuring element 3, and the wires 1-4, 2-5, and 3-7 are connected respectively. After the tail clip is fixed, the three connecting pieces 1-3 are pressed together with the second connecting piece 1-2 to form an encapsulation cavity 102. Finally, point E is pressed together to completely close the pocket-shaped structure and form an accommodating cavity 103.

[0037] It is worth noting that when the third connecting piece 1-3 is pressed together with the second connecting piece 1-2, and when it is pressed together at point E, the above-mentioned wires and temperature measuring element 3 are fixed in a saddle-like manner. This not only improves the fixing effect of the wires, but also allows the temperature measuring element 3 to be placed in a relatively independent small cavity, keeping the temperature measuring element 3 away from the heating element 21. This avoids the problem of inaccurate temperature measurement caused by the heating element 21 heating itself.

[0038] Example 2 like Figure 4 , Figure 5 As shown, based on the first embodiment described above, the difference between this second embodiment and the first embodiment is that, in this second embodiment, columnar airbags 10 are provided in the gaps between adjacent connecting partitions 9 and between the connecting partitions 9 and the inner wall of the liquid filling cavity 101. The columnar airbags 10 can fill and occupy space, thereby reducing the amount of liquid in the liquid filling cavity 101 and reducing the overall weight of the seat cushion 1.

[0039] In a further optimized design, the columnar airbags 10 are connected by a connecting tube 11. One columnar airbag 10 located between the connecting partition 9 and the inner wall of the liquid filling cavity 101 is connected to the inflation nozzle 12 through an air guide tube. The inflation nozzle 12 is connected to the seat cushion body 1.

[0040] In this second embodiment, the inflation nozzle 12 is fixedly mounted on the first connecting piece 1-1; gas can be injected into the columnar airbag 10 through the inflation nozzle 12 and the air guide tube; and all the columnar airbags 10 can be connected internally through the connecting tube 11.

[0041] It should be noted that the inflation nozzle 12 has a one-way airflow function, meaning that gas can only enter the cylindrical airbag 10 through the inflation nozzle 12 and cannot flow back. Furthermore, in order to improve the sealing between the inflation nozzle 12 and the first connecting piece 1-1, a sealing ring is fixed to the inner wall of the first connecting piece 1-1, and the sealing ring tightly wraps around the outer periphery of the inflation nozzle 12.

[0042] In a further optimized design, the surface of the first connecting piece 1-1 is provided with multiple grooves 14. These grooves 14 can reduce pressure on the user's hemorrhoids, thereby alleviating the pain of hemorrhoid sufferers.

[0043] Example 3 like Figure 6As shown, based on the above embodiment one or embodiment two, the difference between this embodiment three and the above embodiment one or embodiment two is that: in this embodiment three, the outer periphery of the cushion bladder 1 is covered with a protective sleeve 13, and the protective sleeve 13 is provided with an opening for the wire three 7 to pass through; and a zipper structure is provided on one side of the protective sleeve 13, through which the cushion bladder 1 can be exposed to add water to the liquid filling cavity 101 or add air to the columnar air bladder 10.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
