Description

Technical Field

[0001] This utility model relates to the field of mattresses, and in particular to an inflatable mattress. Background Technology

[0002] Inflatable mattresses, as a portable sleep tool, are widely used in outdoor camping, temporary accommodation, and other scenarios due to their convenient storage and lightweight characteristics.

[0003] In existing technology, air mattresses use a single-chamber or simply partitioned air-chamber structure, and can be used after being inflated by an electric or manual air pump. However, this technology has the following problems: (1) Due to the lack of zoned support design for the human body curve, the overall hardness is high after inflation and the overall surface is flat, which does not conform to ergonomics. Long-term use may cause the waist to be suspended or local pressure. (2) Most air mattresses have a fixed height air chamber structure for the pillow part, which cannot be adjusted according to the user's body shape or sleeping habits. This can easily lead to insufficient neck support or excessive bending. This uniform design is difficult to meet the different needs of different users for sleep comfort, especially in terms of spinal health support and personalized adaptation. (3) The surface material of existing air mattresses is mostly made of polymer materials such as PVC (polyvinyl chloride) or TPU (thermoplastic polyurethane), which have certain waterproof and wear-resistant properties, but cannot provide users with a comfortable and soft touch, especially in the more sensitive head and waist areas, where the comfort is poor.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] This embodiment provides an inflatable mattress, as shown in the reference. Figures 1 to 4 The inflatable mattress includes an inflatable mattress body 1 and at least one support portion 2.

[0030] The inflatable mattress body 1 includes an upper fabric layer 101 and a lower fabric layer 102. The edges of the upper fabric layer 101 and the lower fabric layer 102 are sealed together (including but not limited to bonding, welding, or integral connection). A mattress body ventilation valve (not shown) is provided at the seam of the upper fabric layer 101, the lower fabric layer 102, or the upper fabric layer 101 and the lower fabric layer 102. The upper fabric layer 101 and the lower fabric layer 102 may be made of materials such as TPU cast fabric.

[0031] Each support part 2 includes an upper fabric layer 201, a lower fabric layer 202, and an air spring 3. The edge of the upper fabric layer 201 is sealed and joined with the edge of the lower fabric layer 202 (including but not limited to bonding, welding, or integral connection). The air spring 3 is longitudinally arranged between the upper fabric layer 201 and the lower fabric layer 202, and the upper end of the air spring 3 is connected to the upper fabric layer 201 (including but not limited to bonding or welding). A vent is provided at the joint of the upper fabric layer 201 or the lower fabric layer 202 or the upper fabric layer 201 and the lower fabric layer 202. A vent is provided on the air spring 3. The vent is connected to the vent and a support part vent valve 4 is provided at the connection.

[0032] In use, the height of the support part 2 is controlled by inflating the air spring 3 through the air valve 4 of the support part and controlling the amount of air. The support part 2 can be selectively set on multiple key parts (such as the head, waist, etc.) on the upper surface of the inflatable mattress body 1. Each support part 2 can work independently without interfering with each other. Each support part 2 is supported by the air spring 3 and adjusted to an appropriate height according to the user's needs, so that the inflatable mattress can adapt to the body characteristics of different user groups (adults, children, etc.), meet ergonomics, improve user comfort, and enhance the user experience.

[0033] The inflatable mattress provided in this embodiment enables dynamic support adjustment for key body support areas of the user. This inflatable mattress is not only suitable for ordinary home or camping scenarios, but can also be extended to medical care fields (such as prevention of bedsores and postoperative positioning management) or vehicle rest systems.

[0034] In this embodiment, optionally, the edges of the upper fabric layer 201 and the lower fabric layer 202 are sealed together by bonding or welding, effectively preventing air leakage while ensuring structural strength; the connection between the air spring 3 and the upper fabric layer 201 is also reliably fixed by bonding or welding, avoiding delamination or displacement caused by repeated inflation and deflation. The overall structure is compact and robust, extending the product's service life.

[0035] like Figure 3 As shown, in an optional embodiment of this example, the upper fabric layer 201 of the support 2 includes a polymer film 21, a sponge 22, and a cover cloth 23 stacked from bottom to top; the polymer film 21 is fixedly connected to the top surface of the air spring 3 (including but not limited to bonding or welding), and the edge of the cover cloth 23 is sealed to the edge of the lower fabric layer 202 (including but not limited to bonding or welding). The polymer film 21, the sponge 22, and the cover cloth 23 are provided with interconnected vents to form a vent. The polymer film 21 includes, but is not limited to, TPU film.

[0036] In this optional embodiment, the polymer membrane 21 (such as TPU membrane) has excellent airtightness, strength and flexibility. It is used as the installation medium between the air spring 3 and the sponge 22. The sponge 22 is placed between the polymer membrane 21 and the cover cloth 23, which increases the softness and cushioning performance of the support. Users can customize the sponge 22 into U-shaped pillows, supports with surface depressions or other shapes according to their needs, so as to achieve close support for the head, neck and other parts, and significantly improve the comfort experience when lying down.

[0037] like Figure 4As shown, in an optional embodiment of this example, the air spring 3 includes multiple sets of inflatable spring units 31; each set of inflatable spring units 31 includes multiple air rings 32 connected in series longitudinally; in each pair of adjacent sets of inflatable spring units 31, at least one air ring 32 of one set of inflatable spring units 31 is connected to at least one air ring 32 of the adjacent set of inflatable spring units 31 through an inflation pipe 33. In this optional embodiment, by designing the air spring 3 as multiple sets of inflatable spring units 31, and with each set of inflatable spring units 31 consisting of multiple air rings 32 connected in series longitudinally, a more stable and uniformly distributed support structure is formed. This design can better distribute pressure and improve the overall stability and support performance of the support.

[0038] In an optional embodiment of this example, the number of air rings 32 connected in series longitudinally in each pair of adjacent air spring units 31 is the same and odd. One air ring 32 located in the middle of the longitudinal direction of one group of air spring units 31 is connected to another air ring 32 located in the middle of the longitudinal direction of an adjacent group of air spring units 31 via an air tube 33. The remaining air rings 32 are independent of each other. In this optional embodiment, by establishing a connection between the air rings 32 in the middle of the longitudinal direction of adjacent groups of air spring units 31, dynamic gas balance can be achieved between different areas of the support 2. When the user moves or changes position on the air mattress, the gas can flow rapidly to adapt to the new pressure distribution. At the same time, the remaining independent air rings 32 can maintain their respective air pressure, ensuring the comfort of local support, thereby providing a more comfortable lying experience.

[0039] Reference Figure 3 In an optional embodiment of this example, the inflatable mattress body 1 includes an upper fabric layer 101, a lower fabric layer 102, and a tensioning rib 103. The edges of the upper fabric layer 101 and the lower fabric layer 102 are sealed together (including but not limited to bonding, welding, or integral connection). The tensioning rib 103 is located between the upper fabric layer 101 and the lower fabric layer 102, with its upper end connected to the upper fabric layer 101 (including but not limited to bonding or welding) and its lower end connected to the lower fabric layer 102 (including but not limited to bonding or welding). A ventilation port 3 is provided at the seam of the upper fabric layer 101, the lower fabric layer 102, or the upper fabric layer 101 and the lower fabric layer 102. A mattress body ventilation valve (not shown) is located inside the ventilation port 3. In this optional embodiment, by providing a tensioning rib 103 inside the inflatable mattress body 1, the support performance of the mattress body can be enhanced, preventing excessive deformation or collapse of the mattress body during use.

[0040] In some alternative embodiments of this example, the support part 2 and the inflatable mattress body 1 are separately configured.

[0041] In some optional embodiments of this example, the lower fabric layer 202 of the support part 2 is fixedly connected to the upper fabric layer 101 of the inflatable mattress body 1. The specific fixed connection method includes, but is not limited to, fixed connections that are non-removable after being fixed by bonding or welding, or fixed connections that are detachable by Velcro, buckles, etc.

[0042] In an optional embodiment of this example, the lower surface of the lower fabric layer 202 of the support part 2 shares the same structure with the upper surface of the upper fabric layer 101 of the inflatable mattress body 1.

[0043] In an optional embodiment of this example, the support portion 2 includes a headrest.

[0044] In an optional embodiment of this example, the support 2 includes a waist support.

[0045] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments.
