Abstract
Description
Technical Field
[0001] This utility model belongs to the field of inflatable seat cushion technology, specifically relating to an inflatable seat cushion with self-heating function. Background Technology
[0002] An inflatable seat cushion is a portable inflatable device that inflates and deflates quickly via an inflation valve. It provides soft cushioning and support during use, making it suitable for outdoor camping and as temporary seating. Its lightweight and foldable design makes it easy to store, balancing comfort and practicality, making it a multi-functional tool for enhancing leisure experiences or emergency use.
[0003] In existing technologies, when outdoor camping is conducted in low-temperature environments, inflatable seat cushions, while insulating the ground's coldness through an air layer, can still cause rapid heat loss due to the thermal conductivity of the cushions when the ambient temperature drops below 5°C. Prolonged use of these cushions can lead to hypothermia. The conventional approach is to use external electric heating pads or hand warmers. However, this method suffers from problems such as localized overheating or low thermal efficiency due to a mismatch between the heating area and the cushion's contact surface. Furthermore, carrying additional heating equipment increases the size of the gear and the complexity of its use. Utility Model Content
[0004] This utility model provides an inflatable seat cushion with a self-heating function, which aims to achieve the purpose of existing inflatable seat cushions while also providing heating function.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An inflatable seat cushion with a self-heating function is provided, comprising an outer cover having an openable and closable filling space; the outer cover also having a front and a back opposite the front; an inflatable airbag is provided in the filling space, and the inflatable airbag is connected to the outer cover; the inflation valve of the inflatable airbag is fixedly connected to the outer cover; a heating pad is also provided in the filling space, the heating pad being located on the side of the inflatable airbag facing the front of the outer cover, the heating pad using alloy fiber as a heating element, and the heating pad having an electrical connection end detachably connected to the outer cover.
[0006] In one possible implementation, the inflatable seat cushion with self-heating function further includes a heat insulation layer disposed in the filling space, located between the inflatable airbag and the heating pad, and connected to the outer cover.
[0007] In one possible implementation, the center of the heating pad is connected to the heat insulation layer, and around the center of the heating pad, the outer periphery of the heating pad is provided with a plurality of elastic bands, the other end of each elastic band extending outward and detachably connected to the edge of the heat insulation layer.
[0008] In one possible implementation, the self-heating inflatable seat cushion further includes an insulating layer disposed in the filling space and located on the side of the heating pad facing the front of the outer cover, and connected to the outer cover.
[0009] In one possible implementation, the back of the outer cover is evenly distributed with multiple silicone anti-slip pads.
[0010] In one possible implementation, the outer cover has a pocket on its side for storing a power source.
[0011] In one possible implementation, the center of the heating pad is connected to the inflatable airbag, and a plurality of elastic bands are provided around the center of the heating pad, with the other end of each elastic band extending outward and connected to the edge of the inflatable airbag.
[0012] In one possible implementation, the heating element is arranged in a serpentine pattern.
[0013] In this implementation, the outer cover, through its internal filling space, ensures that the inflatable airbag and heating pad are enclosed within it, making the heating pad internal. This guarantees the compatibility of the heating pad with the outer cover and the inflatable airbag, while also increasing convenience. Furthermore, the heating pad uses alloy fibers as the heating element. Alloy fibers possess high elasticity, high strength, and good flexibility, allowing them to adapt to the expansion and contraction of the inflatable airbag. Moreover, alloy fibers shorten the time to reach the target temperature and also offer good energy-saving effects. By combining the outer cover, the inflatable airbag, and the heating pad containing alloy fibers as the heating element, the inflatable seat cushion can simultaneously and intermittently self-heat, making it highly practical.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] Please refer to the following: Figure 1 and Figure 2 The present invention provides an inflatable seat cushion with self-heating function. The inflatable seat cushion with self-heating function includes an outer cover 10, which has an openable and closable filling space. The outer cover 10 also has a front and a back opposite the front. An inflatable airbag 20 is provided in the filling space and is connected to the outer cover 10. The inflation valve 21 of the inflatable airbag 20 is fixedly connected to the outer cover 10. A heating pad 30 is also provided in the filling space, located on the side of the inflatable airbag 20 facing the front of the outer cover 10. The heating pad 30 uses alloy fiber as a heating element 31 and has an electrical connection terminal 32 connected to the outer cover 10.
[0021] The self-heating inflatable seat cushion provided in this embodiment, compared with the prior art, allows the outer cover 10 to enclose the inflatable airbag 20 and the heating pad 30 through its internal filling space, making the heating pad 30 a built-in component. This ensures the matching of the heating pad 30 with the outer cover 10 and the inflatable airbag 20, and also increases convenience. Furthermore, the heating pad 30 uses alloy fiber as the heating element 31. Alloy fiber has high elasticity, high strength, and good softness, which can adapt to the expansion and contraction of the inflatable airbag 20. Moreover, alloy fiber can shorten the time to reach the target temperature and also has good energy-saving effects. By combining the outer cover 10, the inflatable airbag 20, and the heating pad 30 containing alloy fiber as the heating element 31, the inflatable seat cushion can simultaneously and intermittently self-heat, making it highly practical. Of course, the filling space of the outer cover 10 is openable and closable, and the electrical connection terminal 32 of the heating pad 30 is detachably connected to the outer cover 10, which can ensure that the heating pad 30 can be easily removed, thereby realizing the convenient replacement or cleaning of the heating pad 30.
[0022] In this embodiment, the heating pad 30 uses alloy fiber as the heating element 31, which heats up quickly and can be driven by a low-power power supply. For example, it only requires a 5V / 1A or 12V / 1A mobile power supply to drive it, further increasing convenience and energy saving.
[0023] It should be noted that the inflation valve 21 can be directly and fixedly connected to the outer cover 10, for example, by adhesive bonding, with only the valve port of the inflation valve 21 located on the surface of the outer cover 10. The electrical connection terminal 32 can be an electrical connection socket, which can be fixedly connected to the outer cover 10, for example, by adhesive bonding. This socket can also be a waterproof socket, such as Type-C, and located on the surface of the outer cover 10.
[0024] It should also be noted that a control module can be installed between the heating pad 30 and the electrical connection terminal 32. This control module can ensure self-regulation of temperature. This technology is existing technology and will not be described in detail here.
[0025] The filling space of the outer cover 10 can be opened and closed, which can be achieved by zippers, Velcro, etc. on the side of the outer cover 10, so as to ensure that it can directly correspond to the heating pad 30 when opened. This structure is existing technology and will not be described in detail here.
[0026] In some embodiments, see Figure 1 The aforementioned outer cover 10 can be adopted as follows: Figure 1 The structure shown. See also Figure 1 An insertion port for the electrical connection terminal 32 of the heating pad 30 can be provided on the side of the outer cover 10. The installation of this port ensures that the power supply module outside the outer cover 10 is electrically connected to the electrical connection terminal 32 of the heating pad 30. At the same time, it also ensures that the heating pad can be easily disassembled and replaced.
[0027] In some embodiments, see Figure 2 The inflatable seat cushion with self-heating function also includes a heat insulation layer 40, which is disposed in the filling space and located between the inflatable airbag 20 and the heating pad 30, and is connected to the outer cover 10.
[0028] The heat insulation layer 40 is disposed between the inflatable airbag 20 and the heating pad 30. The heat insulation layer 40 can be a sheet of heat insulation cotton. The heat insulation layer 40 can prevent the heating pad 30 from transferring heat to the inflatable airbag 20, thereby preventing the inflatable airbag 20 from being damaged due to excessive local temperature. At the same time, it can prevent the inflatable airbag 20 from aging faster due to being in a high-temperature environment for a long time, thus improving safety and service life.
[0029] In some embodiments, see Figure 3 The center of the heating pad 30 is connected to the heat insulation layer 40. Around the center of the heating pad 30, a plurality of elastic bands 33 are provided on the outer periphery of the heating pad 30. The other end of each elastic band 33 extends outward and is detachably connected to the edge of the heat insulation layer 40.
[0030] In this embodiment, regarding the elastic band 33, one end is fixedly connected to the heating pad 30, and the other end may be provided with a collar. Correspondingly, multiple hanging parts, such as buttons, may be provided on the heat insulation layer 40 that correspond one-to-one with the collars of each elastic band 33.
[0031] The inflation of the airbag 20 involves an expansion and contraction process. After inflation, the airbag 20 extends outwards towards the front of the outer cover 10, pushing up the heat insulation layer 40. This heat insulation layer 40, in turn, pushes up the heating pad 30. This stretching of the heating pad 30 stretches the heating element. Although the heating element is made of highly elastic and flexible material, prolonged stretching will still reduce its lifespan. In this embodiment, the heating pad 30 is fixed to the center of the heat insulation layer 40, specifically using Velcro or buttons. This ensures that most of the heating pad 30 is slidably connected to the heat insulation layer 40, allowing it to slide relative to the layer. This sliding reduces the stretching of the heating element 31, effectively preventing stretching. Multiple elastic bands 33 are arranged around the outer periphery of the heating pad 30. One end of each elastic band 33 is connected to the heating pad 30, and the other end is connected to the edge of the heat insulation layer 40. This structure can ensure that the heat insulation layer 40 recovers after the airbag 20 is inflated. At the same time, each elastic band 33 pulls the heating pad outward to ensure that the heating pad can be flattened. This prevents the heating pad from wrinkling or folding inside the outer cover 10 due to the frequent inflation and deflation of the airbag 20, thereby ensuring the stability of the heating pad 30.
[0032] In some embodiments, see Figure 2 The inflatable seat cushion with self-heating function also includes a protective layer 50, which is disposed in the filling space and located on the side of the inflatable airbag 20 facing the back of the outer cover 10, and is connected to the outer cover 10.
[0033] The protective layer 50 is located on the side of the inflatable airbag 20 facing the back of the outer cover 10, mainly to prevent penetration by sharp external structures, thereby effectively protecting the inflatable airbag 20.
[0034] In this embodiment, one possible implementation is that the protective layer 50 can be a composite material of elastic fabric and PVC superimposed.
[0035] In some embodiments, see Figure 2 The inflatable seat cushion with self-heating function also includes an insulating layer 60, which is disposed in the filling space and located on the side of the heating pad 30 facing the front of the outer cover 10, and is connected to the outer cover 10.
[0036] The insulating layer 60 can be located on the outside of the heating pad 30 to prevent current leakage from the heating pad 30, thereby ensuring the safe use of the whole.
[0037] In some embodiments, the outer cover 10 may be adopted as follows: Figure 2 The structure shown. See also Figure 2The back of the outer cover 10 is evenly distributed with multiple silicone anti-slip pads 70 pieces. This structure ensures that the back of the outer cover 10 can be placed on any object to have an anti-slip effect, thereby ensuring its stability during use.
[0038] In some embodiments, the outer cover 10 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The outer cover 10 has a pocket 80 on the side for storing the power supply.
[0039] In this embodiment, the heating element 31 of the heating pad 30 is made of alloy fiber, so the power required is not too high and can be a small portable power bank. Because the portable power bank is small in size, it can be placed directly in the pocket 80, which is convenient for storage and ensures cleanliness during use.
[0040] In some embodiments, the heating pad 30 described above can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The heating element 31 is arranged in a serpentine pattern, which can increase the coverage area and thus ensure the heating effect.
[0041] In some embodiments, the outer cover 10 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The outer cover 10 can be a cuboid shape.
[0042] The outer cover 10 has two opposing rectangular contact surfaces, one of which is the front and the other is the back. The outer cover 10 also has four side surfaces surrounding the contact surfaces. The outer cover 10 can expand after the inflatable airbag 20 inflates, at which point the side surfaces are unfolded. Conversely, the outer cover 10 can also retract after the inflatable airbag 20 deflates, at which point the side surfaces are folded.
[0043] Correspondingly, the dimensions of the inflatable airbag 20, heating pad 30, heat insulation layer 40, protective layer 50, and insulating layer 60 can be adapted to each contact surface to ensure connection stability and thermal uniformity.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
