Description

Technical Field

[0001] This application relates to the field of pillows, and more particularly to an inflatable pillow. Background Technology

[0002] A pillow is a type of bedding used to improve sleep quality and comfort. Pillows typically support the head and neck, protecting the normal physiological curvature of the neck, allowing users to maintain a good sleeping posture and improving sleep quality.

[0003] Inflatable pillows, as a type of portable pillow, maintain a stable volume and shape when inflated, and shrink in size when deflated, allowing them to be folded or rolled up at will. Therefore, they can be used in daily home life and carried on trips to meet users' sleep needs. Currently, most inflatable pillows on the market generally include an inflatable and deflateable gas chamber. The amount of air added controls the pressure within the gas chamber, thus adjusting the pillow's firmness. While inflatable pillows offer advantages such as portability and adjustable firmness, the material used for the inflatable surface is usually non-breathable to ensure a tight seal. This means the support provided to the user's head and neck is largely affected by the internal air pressure, resulting in inconsistent support during use. Utility Model Content

[0004] In order to improve the stability of the support effect of the inflatable pillow on the user's head and neck, this application provides an inflatable pillow.

[0005] The inflatable pillow provided in this application adopts the following technical solution:

[0006] An inflatable pillow, comprising:

[0007] The cushion body includes:

[0008] A sheet of dough, having a first edge;

[0009] The upper piece has a second edge, which is connected to the first edge;

[0010] A filling chamber is defined by the faceplate and the upper plate;

[0011] The filling material is located in the filling chamber;

[0012] A support body, connected to the pad body, includes:

[0013] Top edge, with a fourth edge;

[0014] The film has a fifth edge, which is connected to the fourth edge;

[0015] A supporting chamber is defined by the top plate and the bottom plate;

[0016] An inlet / outlet valve is fluidly connected to the support chamber for filling and releasing air into the support chamber;

[0017] The face sheet is connected to the upper sheet to restrict the position of the filler.

[0018] By adopting the above technical solution, when the inflatable pillow is in use, the support chamber of the support body is filled with gas to form a relatively stable support height. The filling material in the filling chamber of the pad provides stable elastic support to the surface. When the user's head and neck contact the surface of the pad, the surface is depressed downwards due to the pressure from the user's head and neck. The degree of downward depression of the surface is limited by the air pressure in the support chamber and the elasticity of the filling material. Furthermore, the filling material is restricted by the connection between the surface and the upper piece, making it less likely to move or fold. The state of the filling material in the filling chamber is more stable, which in turn makes the surface of the surface flatter and the depression effect of the surface more stable. In other words, the inflatable pillow provides more stable support to the user's head and neck when in use.

[0089] The following is in conjunction with the appendix Figure 1-14d This application will be described in further detail.

[0090] Reference Figure 1 The inflatable pillow includes a cushion body 100 and a support body 200. The cushion body 100 is located above the support body 200 and they are connected to each other. That is, when the inflatable pillow is in use, the cushion body 100 contacts the head and neck area of ​​the user, while the support body 200 does not contact the head and neck area. Figure 2The cushion 100 includes an upper edge 170 that surrounds the perimeter of the cushion 100; the support 200 includes a lower edge 250 that surrounds the perimeter of the support 200. The upper edge 170 of the cushion 100 and the lower edge 250 of the support 200 are connected to each other to form a complete and structurally stable inflatable pillow.

[0091] Reference Figure 2 and Figure 3 The pad 100 includes a face sheet 110 and an upper sheet 130. The face sheet 110 of the pad 100 has a first edge 111 surrounding its perimeter. The upper sheet 130 of the pad 100 has a second edge 131 surrounding its perimeter. The first edge 111 of the face sheet 110 and the second edge 131 of the upper sheet 130 are welded together to form the upper perimeter edge 170 of the pad 100. That is, the upper perimeter edge 170 of the pad 100 is formed by connecting the first edge 111 of the face sheet 110 and the second edge 131 of the upper sheet 130. The pad 100 also includes a filler 120, specifically, combined with... Figure 4 and Figure 5A filling chamber 140 is defined between the face sheet 110 and the upper sheet 130 of the pad 100, and the filler 120 is located in the filling chamber 140. The filler 120 is made of an insulating material, such as polyester fiber or insulating cotton, etc., preferably polyester fiber. The filler 120 is sheet-shaped with a certain uniform thickness, and the outline area of ​​the filler 120 is smaller than the outline area of ​​the face sheet 110 and the upper sheet 130, that is, the edge of the filler 120 is located in the filling chamber 140 and will not contact the first edge 111 of the face sheet 110 or the second edge 131 of the upper sheet 130. The lower surface of the sheet-shaped filler 120 is attached to the upper sheet 130, and the upper surface of the sheet-shaped filler 120 is attached to the face sheet 110. Furthermore, the portion of the face piece 110 inside the first edge 111 is connected to the portion of the upper piece 130 inside the second edge 131 by welding, and corresponding first weld 112 and second weld 132 are formed on the face piece 110 and the upper piece 130, respectively. That is, the first weld 112 is formed on the surface of the face piece 110, and the second weld 132 is formed on the surface of the upper piece 130. The number of first welds 112 on the surface of the face piece 110 and the number of second welds 132 on the surface of the upper piece 130 are equal, the shapes are the same, and the positions correspond one-to-one. For example, both the first weld 112 and the second weld 132 are wavy. Furthermore, the filler 120 is preferably made of a weldable material, such as polyester fiber. The portion of the filler 120 between the first weld 112 and the second weld 132 is welded and fixed to the face sheet 110 and the upper sheet 130. Thus, the sheet-like filler 120 is fixed by the first weld 112 and the second weld 132 so that the filler 120 will not move in the filling chamber 140. That is, the position of the filler 120 is restricted by connecting the face sheet 110 and the upper sheet 130, thereby stabilizing the surface structure of the face sheet 110. At the same time, a protruding texture is formed between the first welds 112 on the surface of the face sheet 110.

[0092] Reference Figure 3 and Figure 4The support body 200 includes a top plate 210 and a bottom plate 230. The top plate 210 of the support body 200 has a fourth edge 211 surrounding its perimeter. The bottom plate 230 of the support body 200 has a fifth edge 231 surrounding its perimeter. The fourth edge 211 of the top plate 210 and the fifth edge 231 of the bottom plate 230 are welded together to form the lower perimeter edge 250 of the support body 200. That is, the lower perimeter edge 250 of the support body 200 is a welded edge formed by welding the fourth edge 211 of the top plate 210 and the fifth edge 231 of the bottom plate 230. The support body 200 also includes a tensioning member 220. Specifically, a support chamber 240 is defined between the top plate 210 and the bottom plate 230 of the support body 200, and the tensioning member 220 is located in the support chamber 240. The tensioning member 220 is a rectangular sheet with an upper side 221 and a lower side 222. The upper side 221 of the tensioning member 220 is fixed to the top plate 210 by welding, forming a fourth weld 212 on the top plate 210. The lower side 222 of the tensioning member 220 is fixed to the bottom plate 230 by welding, forming a fifth weld 232 on the bottom plate 230. In this embodiment, the tensioning member 220 is a sheet material, and the sheet-like tensioning members 220 are parallel to each other and equidistantly distributed in the support chamber 240. In an alternative embodiment, the tensioning member 220 can also be a wire-pull structure made of multiple pull wires, or the tensioning member 220 can also be a wire material, etc. Furthermore, the film 230 has a vent 233, which is in fluid communication with the support chamber 240. An inlet / outlet valve is fixedly installed at the vent 233, which is in fluid communication with the support chamber 240. The user can fill or release gas into the support chamber 240 through the inlet / outlet valve.

[0093] Furthermore, refer to Figure 5 In this embodiment, the upper edge 170 of the pad 100 and the lower edge 250 of the support 200 are fixedly connected to each other by welding, gluing, or sewing. Specifically, the first edge 111 of the face piece 110, the second edge 131 of the upper piece 130, the fourth edge 211 of the top piece 210, and the fifth edge 231 of the bottom piece 230 are fixedly connected by welding, thereby forming a complete inflatable pillow. In other optional embodiments, the upper edge 170 of the pad 100 and the lower edge 250 of the support 200 are detachably connected by a connector. Specifically, the connector includes an upper connecting part and a lower connecting part. The upper connecting part is fixed to the upper edge 170 of the pad 100, and the lower connecting part is fixed to the lower edge 250 of the support 200. The upper connecting part and the lower connecting part are detachably connected, thereby detachably connecting the pad 100 and the support 200. Specifically, the connector can use a zipper, Velcro, or snap fastener, etc.

[0094] Reference Figure 6In an optional embodiment, the sheet-like filler 120 has limiting holes 121. The number of limiting holes 121 is equal to the number of first welds 112, the shape of the limiting holes 121 is the same as the shape of the first welds 112, and the positions of the limiting holes 121 correspond one-to-one with the positions of the first welds 112. Correspondingly, the number of limiting holes 121 is also equal to the number of second welds 132, the shape of the limiting holes 121 is the same as the shape of the second welds 132, and the positions of the limiting holes 121 correspond one-to-one with the positions of the second welds 132. The face sheet 110 and the upper sheet 130 are welded and fixed to each other in the limiting holes 121, that is, the first weld 112 of the face sheet 110 and the second weld 132 of the upper sheet 130 are located in the corresponding limiting holes 121 of the filler 120. The filler 120 is constrained by the first weld 112 and the second weld 132, making it less prone to movement. That is, the faceplate 110 is connected to the upper plate 130 to restrict the position of the filler 120. Simultaneously, because the filler 120 has a limiting hole 121, the welding between the faceplate 110 and the upper plate 130 is less obstructed. That is, the faceplate 110 and the upper plate 130 can be directly welded, and the filler 120 is not welded. In this case, the material replacement range for the filler 120 is wider; that is, the filler 120 can also be made of non-weldable materials.

[0095] Reference Figure 7 and Figure 8In some alternative embodiments, the pad 100 further includes an upper edge 171, which is located outside the upper edge 170, i.e., the upper edge 171 surrounds the outer periphery of the upper edge 170; the support 200 further includes a lower edge 251, which is located outside the lower edge 250 of the support 200, i.e., the lower edge 251 surrounds the outer periphery of the lower edge 250. The upper edge 171 and the lower edge 251 are interconnected to connect the pad 100 and the support 200, i.e., the upper edge 170 of the pad 100 and the lower edge 250 of the support 200 are not connected, and the pad 100 and the support 200 are connected only through the connection of the upper edge 171 and the lower edge 251. Specifically, the upper edge 171 and the lower edge 251 can be fixedly connected to each other by welding, gluing, or sewing; they can also be detachably connected by connectors such as zippers, Velcro, or snap fasteners. That is, the inflatable pillow includes connectors, which have an upper connecting part fixed to the upper edge 171 and a lower connecting part fixed to the lower edge 251, and the upper connecting part and the lower connecting part are detachably connected. Furthermore, the upper edge 171 can be made of a material integral with the surface piece 110, that is, the surface piece 110 of the pad 100 has an edge surrounding the first edge 111 in addition to its first edge 111. After the first edge 111 of the surface piece 110 is welded and fixed to the second edge 131 of the upper piece 130, the portion of the surface piece 110 outside the first edge 111 forms the upper edge 171 of the pad 100. Alternatively, the upper edge 171 can also be made of the same material as the upper sheet 130. Similarly, the lower edge 251 can be made of the same material as the top sheet 210, or the lower edge 251 can also be made of the same material as the bottom sheet 230.

[0096] Reference Figures 9 to 11In an optional embodiment, the pad 100 further includes a lower piece 150, which is located below the upper piece 130, i.e., between the upper piece 130 and the support 200. The lower piece 150 has a third edge 151 surrounding its perimeter. The third edge 151 of the lower piece 150, together with the second edge 131 of the upper piece 130 and the first edge 111 of the face piece 110, are welded together to form the upper perimeter edge 170 of the pad 100. That is, the upper perimeter edge 170 of the pad 100 is formed by connecting the first edge 111 of the face piece 110, the second edge 131 of the upper piece 130, and the third edge 151 of the lower piece 150. Further, a development chamber 160 is defined between the upper piece 130 and the lower piece 150 of the pad 100. The portion of the upper sheet 130 inside the second edge 131 and the portion of the lower sheet 150 inside the third edge 151 are welded together at the position corresponding to the second weld 132, forming a corresponding third weld 152 on the lower sheet 150. The third weld 152 and the second weld 132 divide the molding chamber 160 into multiple spaced-apart molding sub-chambers 161, that is, the molding chamber 160 is divided into multiple molding sub-chambers 161 by the interconnection of the upper sheet 130 and the lower sheet 150. Furthermore, there is a gap between the two ends of the third weld 152 and the third edge 151 of the lower sheet 150, thereby allowing fluid communication between the multiple molding sub-chambers 161 at their two ends. When the molding chamber 160 is inflated, each molding sub-chamber 161 pushes upward the portion of the upper sheet 130, the portion of the filler 120, and the portion of the face sheet 110 at the corresponding position, thereby making the surface texture shape of the face sheet 110 more prominent. Furthermore, the lower piece 150 of the pad 100 has an upper connecting hole 153, which is in fluid communication with the display chamber 160; the top piece 210 of the support 200 has a lower connecting hole 213, which is in fluid communication with the support chamber 240. The upper connecting hole 153 and the lower connecting hole 213 are positioned correspondingly, and the lower piece 150 at the edge of the upper connecting hole 153 and the top piece 210 at the edge of the lower connecting hole 213 are fixedly connected by welding, so that the upper connecting hole 153 and the lower connecting hole 213 are sealed but fluidly connected, thereby allowing the display chamber 160 to be in fluid communication with the support chamber 240. That is, multiple display sub-chambers 161 are all in fluid communication with the support chamber 240. At this time, by inflating or deflating the inlet and outlet valves, the support chamber 240 and the display chamber 160 can be inflated or deflated simultaneously. In an alternative embodiment, the display chamber 160 and the support chamber 240 can also be fluidly connected via a connecting valve. For example, an upper valve body is fixedly installed at the upper connecting hole 153, and a lower valve body is fixedly installed at the lower connecting hole 213. The upper valve body and the lower valve body are sealed and fluidly connected, thereby connecting the support chamber 240 and the display chamber 160.In other optional embodiments, the end of the third weld 152 on the surface of the lower sheet 150 may intersect with the third edge 151 of the lower sheet 150. In this case, the multiple visible sub-cavities 161 are independently isolated from each other, and an upper connecting hole 153 needs to be opened on the lower sheet 150 at the position corresponding to each visible sub-cavity 161. At the same time, a corresponding number of lower connecting holes 213 need to be opened on the top sheet 210. It should be noted that in the above embodiments, the number of third welds 152 on the surface of the lower sheet 150 is equal to the number of second welds 132 on the surface of the upper sheet 130, they have the same shape, and their positions correspond one-to-one. That is, the third weld 152 is also wavy. This is not a limitation. In some other optional embodiments, the third weld 152 on the surface of the lower sheet 150 may not correspond to the second weld 132 on the surface of the upper sheet 130. In this case, after the upper sheet 130 and the lower sheet 150 are welded, more welds are formed on the surface of the upper sheet 130. Optionally, in this embodiment, the pad 100 and the support 200 can also be connected via an upper excess edge 171 and a lower excess edge 251. In this case, the lower piece 150 can have an excess edge surrounding the third edge 151 to form the aforementioned upper excess edge 171, that is, the upper excess edge 171 is made of a material integral with the lower piece 150. In other words, the upper excess edge 171 can be made of a material integral with the surface piece 110, the upper piece 130, or the lower piece 150; the lower excess edge 251 can be made of a material integral with the top piece 210 or the bottom piece 230.

[0097] Reference Figures 12a-12c In an optional embodiment, the texture formed on the surface of the patch 110 can be designed as needed. For example, the plurality of first welds 112 on the surface of the patch 110 can be arranged in an array of rings, such as... Figure 12a In the inflatable pillow, when in use, the surface of the sheet 110 forms a protruding array of circular and star-shaped patterns; or, the surface of the sheet 110 forms a pattern resembling... Figure 12b The diamond-shaped texture in the middle, or the surface of panel 110 forming a pattern like... Figure 12c The honeycomb texture, etc. It is understood that in different embodiments of the first weld 112 on the surface of the sheet 110, the structure of the second weld 132 on the surface of the upper sheet 130 changes accordingly with the structural design of the first weld 112 on the surface of the sheet 110; or, the structure of the second weld 132 on the surface of the upper sheet 130 and the structure of the second weld 132 on the surface of the lower sheet 150 both change accordingly with the structural design of the first weld 112 on the surface of the sheet 110.

[0098] Reference Figure 13 In some alternative embodiments, the faceplate 110 and upper plate 130 of the pad 100 can be interconnected via welding surfaces with perforated portions. Specifically, in conjunction with Figure 14aThe pad 100 has a welding area 300, a fluffy area 400, and a peripheral area 500. The fluffy area 400 is located within the welding area 300, and the peripheral area 500 is located outside the welding area 300. In the welding area 300, the face sheet 110 is welded to the upper sheet 130, and a first welding surface 113 and a second welding surface 133 are formed on the face sheet 110 and the upper sheet 130, respectively. That is, the first welding surface 113 is formed on the surface of the face sheet 110, and the second welding surface 133 is formed on the surface of the upper sheet 130. The number of first welding surfaces 113 on the surface of the face sheet 110 and the number of second welding surfaces 133 on the surface of the upper sheet 130 are equal, their shapes are the same, and their positions correspond one-to-one. Furthermore, the number of first welding surfaces 113 and the number of second welding surfaces 133 are equal, their shapes are the same, and their positions correspond one-to-one with those of the welding area 300. Specifically, the welding surfaces are rectangular with multiple circular cutouts in the center; that is, both the first welding surface 113 and the second welding surface 133 are rectangular with multiple circular cutouts in the center. Further, in the fluffy region 400, a filling chamber 140 is defined between the surface piece 110 and the upper piece 130. The number of filling chambers 140 is equal to the number of fluffy regions 400, they have the same shape, and their positions correspond one-to-one. In other words, the surface piece 110 and the upper piece 130 are interconnected in the welding region 300 and define the filling chamber 140 in the fluffy region 400. Optionally, the sheet-like filler 120 covers the welding area 300 and the fluffy area 400. The portion of the sheet-like filler 120 in the welding area 300 is restricted by the first welding surface 113 and the second welding surface 133 and is not easily moved. That is, the portion of the filler 120 located in the welding area 300 is restricted by the sheet 110 and the upper sheet 130 and is not easily moved. In the fluffy area 400, the filler 120 expands naturally or expands under the certain restriction of the sheet 110 and the upper sheet 130 to push the sheet 110 upward. That is, the sheet 110 in the fluffy area 400 is convex upward by the expansion force of the filler 120 and forms a shape corresponding to the fluffy area 400. Optionally, the filler 120 may also cover the fluffy area 400 and part of the welding area 300. That is, the welding area 300 includes both portions where the sheet 110 and the upper sheet 130 are directly welded together, and portions where the sheet 110, the upper sheet 130, and the filler 120 are simultaneously welded together. In other optional embodiments, the filler 120 may simultaneously cover the welding area 300, the fluffy area 400, and the peripheral area 500. That is, the sheet 110 in both the fluffy area 400 and the peripheral area 500 is bulging upwards due to the expansion force of the filler 120. In some other optional embodiments, the filler 120 may only cover the fluffy area 400. In this case, the filler 120 may also be a non-fixed-shape material, such as non-fixed-shape cotton wool or fiber balls.

[0099] Reference Figures 14a-14dThe quantity, shape, and position of the welding area 300, the fluffy area 400, and the outer perimeter area 500 of the pad 100 can be changed as needed. For example... Figure 14a As shown, the pad 100 has a peripheral region 500, a welding region 300, and six fluffy regions 400. The peripheral region 500 is located outside and surrounds the welding region 300, and the six fluffy regions 400 are all located within the welding region 300 and are arranged in multiple circular arrays. For example... Figure 14b As shown, different Figure 14a The pad 100 has only one welding area 300 and six fluffy areas 400, that is, the pad 100 does not have a peripheral area 500; or for example Figure 14c As shown, the pad 100 has a peripheral region 500, four welding regions 300, and four fluffy regions 400, wherein the four welding regions 300 correspond one-to-one with the four fluffy regions 400, and each fluffy region 400 is located within its corresponding welding region 300; or for example... Figure 14d As shown, the pad 100 has two peripheral regions 500, a welding region 300, and a fluffy region 400, wherein the welding region 300 is located between the two peripheral regions 500, the fluffy region 400 is located within the welding region 300, and so on. The number, shape, and position of the welding region 300, fluffy region 400, and peripheral regions 500 are exemplary and not limiting, and can be varied arbitrarily in actual production.

[0100] It should be noted that, in the corresponding embodiments of this application, the material of the face sheet 110 of the cushion 100 is a breathable material, such as nylon-spandex fabric, pure cotton, or bamboo fiber, etc., preferably nylon-spandex fabric. Therefore, the filling chamber 140 is a non-gas-sealed chamber. During the use of the inflatable pillow, airflow easily flows into or out of the filling chamber 140 through the face sheet 110, meaning the cushion 100 of the inflatable pillow has good breathability. The top sheet 210 and bottom sheet 230 of the support body 200 are both made of non-breathable weldable materials, such as TPU pure film or TPU-coated fabric, etc. Therefore, the support chamber 240 is a gas-sealed chamber. During the use of the inflatable pillow, the support chamber 240 allows the inflatable pillow to maintain its basic shape, thereby ensuring effective support for the user's head and neck. The upper sheet 130 and lower sheet 150 of the pad 100 are made of non-breathable, weldable materials, such as TPU film. Therefore, the shaped chamber 160 is a gas-sealed chamber. During use of the inflatable pillow, the shaped chamber 160 further accentuates the textured shape of the surface sheet 110, providing a more comfortable feel to the user's head and neck. Furthermore, when the surface sheet 110 is compressed, it generates a greater degree of compression, promoting airflow exchange between the filling chamber 140 and the outside airflow, thus improving the breathability of the pad 100. In an alternative embodiment, the surface sheet 110 of the pad 100 can also be made of non-breathable materials, such as TPU fabric.

[0101] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. For example, the welding in this application can be replaced by adhesive or sewing, as long as a similar fixing or sealing effect can be achieved. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
