Description

A water-air multifunctional mattress Technical Field

[0001] This utility model relates to the field of sleep products technology, and in particular to a mattress, especially a water-air multifunctional mattress. Background Technology

[0002] A mattress is an item placed between the human body and the bed to ensure consumers get healthy and comfortable sleep. Mattresses come in a variety of materials, and different materials provide different sleep experiences. With technological advancements, mattress styles have become increasingly diverse, and even mattresses filled with non-solid materials have appeared on the market.

[0003] The prior art (CN104490165A) discloses a water-filled mattress, characterized in that: the water-filled mattress body (1) is an integral structure formed by sealing and connecting two layers of non-woven fabric, and a water valve (2) for filling with water is provided on the side of the water-filled mattress body (1). When filling with water, water can be pumped, tapped, or manually filled into the water-filled mattress body (1) through the water valve (2). After the water is full, the water valve (2) is closed. When draining water, the water in the water-filled mattress body (1) is quickly drained by opening the water valve (2). The entire filling and draining process is convenient and quick. After draining, the water-filled mattress body (1) can be folded up. Due to its small size and light weight, it is very convenient to carry. It is a water-filled mattress with a simple structure, easy manufacturing, and quick filling and draining. Because water has a higher specific heat capacity than any other material used in mattresses, people will feel cool and comfortable when resting on a water-filled mattress in the hot summer. This will make people feel more comfortable throughout the hot weather, save on air conditioning costs, and contribute to energy conservation and emission reduction.

[0004] Furthermore, prior art (CN107224139A) also discloses an inflatable mattress having an upper structure, an inflatable middle layer, and a bottom structure. The upper structure includes a base fabric layer and a cover layer. The base fabric layer is woven from a plurality of fabric fibers, with more than 100 warp and weft fibers per square inch. The cover layer is bonded to the base fabric layer with adhesive, the adhesive weighing more than 20 grams and less than 80 grams per square yard. The base fabric layer is pressed into the cover layer to form a fabric bonding material. The first side of the inflatable middle layer is fixed to the upper structure, and the inflatable middle layer includes at least one air cavity for unfolding into a predetermined shape when inflated, and the outer side of the inflatable middle layer includes the fabric bonding material. The second side of the inflatable middle layer is fixed to the bottom structure.

[0005] However, in the process of implementing the technical solution in the prior art, the applicant discovered the following technical problems in the prior art:

[0006] In existing technologies, mattresses are bulky and difficult to carry. For example, the mattresses mentioned above cannot be folded and are mostly used indoors. As people increasingly enjoy outdoor activities, it is extremely inconvenient to move traditional indoor mattresses outdoors. Furthermore, inflatable mattresses can only adjust height by air volume. When there is too much air, the mattress is too firm, affecting comfort; when there is too little air, the mattress sags, also affecting comfort. Complex self-inflating mattresses increase costs and are not convenient to carry for outdoor use. Additionally, purely inflatable mattresses cannot or do not easily regulate the user's perceived temperature. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a multi-functional water and air mattress, which solves the technical problems of inconvenience and low comfort in the prior art, and at least achieves one of the technical effects of improving the convenience and comfort of use.

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0009] A multifunctional water-air mattress comprises multiple cavities, each cavity having one or more human body receiving parts at its top. Each cavity includes at least a first cavity and a second cavity. The second cavity is enclosed by the first cavity. The first and second cavities are respectively filled with a first fluid and a second fluid, causing the second cavity to float within the first cavity. Each of the first and second cavities has a fluid inlet. Both the first and second cavities are made of an airtight, foldable, non-rigid material.

[0014] Preferably, the density of the first fluid is greater than the density of the second fluid; the fluid inlet is adapted to the fluid inlet / outlet of the external fluid container; and the second cavity is enclosed by the first cavity to form a dual-density structure.

[0015] More preferably, the first bladder and the second bladder are respectively an air cushion and a water bag; wherein, when the water bag is filled with water and the air cushion is filled with air, the water generates buoyancy on the air cushion, and after being inflated, the second bladder can float inside the water-filled first bladder. Except for the necessary fixed points, the other parts are in a free-floating state without being fixed, and the water can also penetrate to the upper surface of the air cushion.

[0016] Particularly preferred, the system also includes a third cavity connected to the first cavity, wherein the first, second, and third cavities are respectively a large air cushion, a water bag, and a small air cushion; the large and small air cushions are composed of multiple air chamber units to form a multi-directional, freely bending structure; the second and third fluids are air, and the first fluid is water; the first and second cavities form a water-air combination structure; the first and second body parts are respectively the legs and the body parts above the legs; the small air cushion supports the legs, and the first and second cavities together support the body parts above the legs.

Detailed Implementation

[0036] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] In existing technologies, when using waterbeds, the buoyancy of water on the human body is limited because the density of the human body is greater than that of water, and very deep water is required to ensure that the body does not stick to solid objects below the waterline. This results in high water consumption and inconvenience. Furthermore, in terms of comfort, the excessively soft nature of water provides insufficient support for the human body, leading to uncomfortable sleep.

[0038] In existing technologies, when using air mattresses, the mattress is too firm when fully inflated, failing to provide a comfortable, pressure-relieving effect on the body. Releasing some air to improve this firmness causes the mattress to lose its shape due to lack of air, failing to achieve a balance of firmness and softness. Furthermore, while air mattresses provide warmth in winter, they are ineffective at cooling the body in summer, thus failing to provide adequate comfort.

[0039] The technical solution of this application provides a water-air multifunctional mattress, which solves the problems of inconvenience and low comfort in the prior art. It achieves the beneficial effects of more close-fitting support and a more comfortable support experience by combining airtight, foldable, non-rigid material cavities with different cavities injected with fluids of different densities and cavities wrapping each other to form a multi-density composite cavity structure.

[0040] The non-rigid material bladder can be folded up after the fluid inside is emptied, making it easy to carry and use.

[0041] The overall concept of the implementation scheme of this utility model to solve the above-mentioned technical problems is as follows:

[0042] A water-air multifunctional mattress comprises multiple cavities, including at least a first cavity 100 and a second cavity 200; the second cavity 200 is enclosed by the first cavity 100; the first cavity 100 and the second cavity 200 are respectively filled with a first fluid and a second fluid so that the second cavity 200 floats in the first cavity 100; the first cavity 100 and the second cavity 200 are respectively provided with fluid inlets 400; wherein the first cavity 100 and the second cavity 200 are both made of airtight, foldable, non-rigid material; the fluid volume in different cavities is adjusted by regulating the fluid inlet and outlet of the fluid inlet 400, and the mattress temperature is adjusted by regulating the fluid temperature.

[0043] Specifically, the first fluid is water and the second fluid is air, thus forming a structure combining water and air.

[0044] More specifically, the second bladder 200, when filled with air, provides support to the human body by combining the supporting force generated when the second bladder 200 floats inside the first bladder 100, which is filled with water.

[0045] More specifically, by utilizing the water depth to be greater than the gas height, the second bladder 200 occupies part of the space of the first bladder 100, thereby reducing the amount of water used.

[0046] Specifically, the structure of the second sac 200, which utilizes the multi-directional free bending characteristics, provides ample coverage for the human body.

[0047] When no water is needed, and the second bladder 200 is not injected with any substance or even air, the water-air multifunctional mattress is a pure air mattress.

[0048] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0049] A multifunctional water-air mattress, as shown in Figure 1, consists of two cavities: a first cavity 100 and a second cavity 200. The second cavity 200 is enclosed by the first cavity 100. The first cavity 100 and the second cavity 200 are filled with water and air, respectively. The first cavity 100 and the second cavity 200 are each provided with a fluid inlet 400 (water or air inlet). The first cavity 100 and the second cavity 200 are both made of an airtight, foldable, non-rigid material, such as a waterproof soft material. The water volume or air volume in the different cavities can be adjusted by regulating the water or air entering and exiting through the fluid inlet 400 (adjustable water nozzle or adjustable air nozzle).

[0050] To further conserve water, as shown in Figure 3, a multi-functional water-air mattress consists of three cavities: a first cavity 100, a second cavity 200, and a third cavity 300. The second cavity 200 is enclosed by the first cavity 100. The first cavity 100 and the third cavity 300 are connected. The first cavity 100, the second cavity 200, and the third cavity 300 are filled with water, air, and air, respectively. Each of the three cavities has a fluid inlet 400 (for water or its inlet). The first cavity 100, the second cavity 200, and the third cavity 300 are all made of an airtight, foldable, non-rigid material, such as a waterproof, soft material. The third cavity 300 supports the lower leg and below, while the combination of the first cavity 100 and the second cavity 200 supports the upper part of the leg. The third cavity 300 reduces the volume of the first cavity 100 to conserve water. The water or air volume in each cavity can be adjusted by regulating the flow of water or air through the fluid inlet 400 (adjustable water nozzle or adjustable air nozzle).

[0051] Specifically, the first cavity 100, the second cavity 200, and the third cavity 300 are respectively a water bag 101, a large air cushion 201, and a small air cushion 301; the first cavity 100 and the second cavity 200 form a water-air combination structure; when the water bag 101 is filled with water and the large air cushion 201 is filled with air, the water generates buoyancy on the air cushion, and the water can also permeate to the upper surface of the air cushion.

[0052] Specifically, the air cushion 201 is composed of multiple air chamber units 210, as shown in Figures 2 and 7. These air chamber units 210 are interconnected, forming a multi-directional free-folding structure that allows for free folding even when the air pressure is saturated. The dotted lines in Figure 7 indicate the folding direction. This multi-directional free-folding structure allows for free bending under any air pressure. Under the weight of the human body, the multiple air chamber units 210 bend with the curves of the body, providing ample coverage. Simultaneously, because the multiple air chamber units 210 bend with the curves of the body under its weight, the contact area increases, reducing pressure on the body and improving sleep quality.

[0053] Furthermore, as shown in Figure 8, water seepage holes 220 are provided between the air chamber units 210. Water from the first chamber 100 can seep through the water seepage holes 220 from below the second chamber 200 to above the second chamber 200 and contact the lower surface of the upper surface of the first chamber 100. The firmness of the water-air multifunctional mattress is determined by the amount of water and air. It can be adjusted according to personal preference or needs. The fluidity of the water allows the body structure to conform to the ergonomic curve of the surface of the water bag 101 when the body lies down, and the buoyancy of the water provides a feeling of pressure relief, avoiding insufficient or excessive support for the body.

[0054] When used outdoors in summer, water can carry away body heat, giving users a cooling sensation.

[0055] When used in winter, since water is not needed to remove heat, water bag 101 does not need to be added. At this time, the water-air mattress becomes a pure air mattress or, with the addition of insulation material, becomes a high-warmth winter mattress.

[0056] Once the water and air in the small air cushion 301, water bag 101, and large air cushion 201 have been drained, they can be folded up and taken away for easy use.

[0057] Although the folded water-air multi-functional mattress is smaller in size, it is still not convenient to carry. A non-rigid storage container is provided between the small air cushion 301 and the water bag 101. It is preferable to use a storage bag. After the small air cushion 301, the water bag 101 and the large air cushion 201 are emptied of water or air, they can be folded and placed in the storage bag, and can be carried by carrying the storage bag.

[0058] The ease of use of a multi-functional water-air mattress depends not only on its portability but also on the ease of operation. Therefore, an opening 110 is provided at the end of the first cavity 100 away from the third cavity 300 to ensure that the interior of the first cavity 100 can be turned outward along the opening 110.

[0059] When water needs to be added, open the opening 110 to fill a whole bucket of water into the first chamber 100 for quick water addition.

[0060] When it is necessary to drain the water from the first bladder 100, open the opening 110 to drain the water directly into the field, and turn the first bladder 100 inside out to expose the second bladder 200 naturally, so as to facilitate drying, cleaning and internal cleaning, and to prevent the growth of bacteria and odors.

[0061] Furthermore, the first cavity 100 has a multi-folded opening 110 at the end furthest from the third cavity 300; the opening 110 has a fitted opening at the point furthest from the first cavity 100, and a fluid inlet 400 is provided on the multi-folded structure of the opening 110. This structure helps to seal water within the first cavity 100. At the same time, a leak-proof zipper 111 is used at the bag opening to improve ease of use and ensure waterproofing.

[0062] Referring to Figures 3-6, the first bladder 100, the second bladder 200, and the third bladder 300 are respectively a water bag 101, a large air cushion 201, and a small air cushion 301. The fluid injection port 400 penetrates the surface of the water bag 101 and extends into the large air cushion 201. An opening 110 is provided at the end of the water bag 101 away from the small air cushion 301 to ensure that the interior of the water bag 101 can be turned outward along the opening 110.

[0063] The opening 110 can be an adhesive (Velcro) opening 110, preferably a leak-proof zipper 111. The width of the opening 110 is similar to the width of the water bag 101.

[0064] Furthermore, as shown in Figures 9-11, the opening 110 is designed with a multi-fold structure. The opening 110 with the multi-fold structure is provided with an adjustable fluid inlet 400 (water inlet or water nozzle), which also has an exhaust function.

[0065] Refer to the diagram showing different folding configurations at the opening, including zipper 111 and Velcro. The faucet is located between the Velcro straps, folding together to achieve waterproofing. To further enhance leak-proof functionality, a leak-proof zipper 111 is used.

[0066] Opening the zipper 111 of the opening 110, as shown in Figure 12, and turning the water bag 101 inside out to dry helps it dry quickly and reduces the breeding ground for bacteria.

[0067] When camping, without power supply, water and gas need to be added manually. To further improve the ease of use of the water-gas multifunctional mattress, an external fluid container is designed. The fluid inlet 400 of the water-gas multifunctional mattress is compatible with the fluid inlet and outlet of the external fluid container, so that water and gas can be added manually to the water-gas multifunctional mattress.

[0068] Specifically, the external fluid containers are an air-filled bag and a water-filled bag 101.

[0069] In use, connect the fluid inlet and outlet of the filled air bag and water bag 101 to the fluid injection port 400 of the water-air multifunctional mattress, and press the air bag and water bag 101 to fill the small air cushion 301, large air cushion 201 and water bag 101 of the water-air multifunctional mattress with water and air.

[0070] By connecting a power fluid circulation device (water pump and air pump) or a power fluid temperature control circulation device (temperature control water pump and air pump), water and air or water and air at a preset temperature can be injected into the mattress.

[0071] When camping in winter, people need a comfortable temperature, so cotton bags or other insulating materials are designed to match the moisture-wicking multi-functional mattress. The entire mattress is covered with these bags or other insulating materials to provide a comfortable temperature.

[0072] To accommodate multiple users simultaneously, the top of the water-air multifunctional mattress is designed to consist of multiple human body accommodating parts 1000, as shown in Figure 13. The top of the water-air multifunctional mattress is designed to consist of three human body accommodating parts 1000.

[0073] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
