Therefore, a mattress that combines comfort and portability is urgently needed to enhance the outdoor camping experience. Utility Model Content

[0004] Based on this, it is necessary to provide a mattress and an inflatable bed to address the problem that the above-mentioned mattresses are difficult to achieve both comfort and portability, which affects the user's experience of outdoor camping.

[0005] In a first aspect, the present application provides a mattress, which adopts the following technical solution:

[0006] A mattress comprises a cushion layer, a cover layer and a filling layer, wherein the cushion layer comprises a first connecting portion arranged along the circumference of the cushion layer, the first connecting portion is arranged to form a first connecting area, and a plurality of first connection points are arranged at intervals in the first connecting area; the cover layer comprises a second connecting portion arranged along the circumference of the cover layer, the second connecting portion is arranged to form a second connecting area, and a plurality of second connection points are arranged at intervals in the second connecting area; the filling layer is arranged between the cushion layer and the cover layer, and at least one connecting channel for the first connection point and / or the second connection point to pass through the filling layer; wherein the second connecting portion is correspondingly connected to the first connecting portion so that an installation cavity is formed between the cover layer and the cushion layer, the filling layer is accommodated in the installation cavity, the second connection points are arranged in a one-to-one correspondence with the first connection points, and are connected by means of the connecting channel; the filling layer is configured to be able to expand and contract along a first direction, and the first direction is defined as the connection direction between the cover layer and the cushion layer.

[0007] In one embodiment, the installation cavity is filled with gas.

[0008] In one embodiment, the projection of the filling layer on the reference plane can cover at least a portion of the projection of the cushion layer on the reference plane; wherein the first direction is perpendicular to the reference plane.

[0009] In one embodiment, the cushion layer and the cover layer are connected by means of a hot pressing process.

[0010] In one embodiment, the filling layer is configured to be made of a flexible material.

[0011] In one embodiment, the cushion layer and the cover layer are configured to be made of wear-resistant and waterproof fabrics.

[0012] In one embodiment, the mattress further comprises a mattress air nozzle, which is installed on the cover layer and / or the cushion layer, and the mattress air nozzle can connect the installation cavity to the outside world.

[0013] In a second aspect, the present application provides an inflatable bed, which adopts the following technical solution:

[0029] As living standards continue to improve, more and more people are enjoying outdoor activities. These activities often require the use of outdoor supplies, such as camping mattresses. Choosing the right camping mattress is crucial for outdoor activities, as it not only affects sleep quality but also warmth and comfort. Currently, the most common camping mattresses on the market fall into three main types: foam, self-inflating, and air mattresses.

[0030] Foam mattresses are made of expanded material, are lightweight and durable, and are suitable for use in spring, summer, and autumn, but lack the warmth needed in cold weather. The advantage of this type of mattress is that it's puncture-resistant and still provides insulation even if damaged. However, its disadvantage is that it's thinner and not suitable for winter or mountain camping.

[0031] Self-inflating mattresses have open-cell foam that expands on its own, making them easy to use and providing good support, making them suitable for a variety of outdoor environments. While these mattresses offer advantages such as portability and comfort, they are also heavy and can leak if punctured.

[0032] Inflatable mattresses require manual or pump inflating and are compact, portable, and offer excellent warmth retention. While these mattresses offer advantages such as lightness, comfort, and compact storage, they are also more expensive, easily punctured by sharp objects, and require a pump or bag to inflate.

[0033] Specifically, inflatable camping mattresses are typically made of two heat-sealed fabric sheets, with air inflated between them to create a mattress for resting. However, these mattresses offer limited comfort and warmth retention. Traditional sponge mattresses are also too thick and heavy, making them difficult to carry when folded. Therefore, there is an urgent need to design a mattress that combines comfort and portability to enhance the user's outdoor camping experience.

[0034] The following is combined with Figure 1-3 The embodiments of the present application are described in further detail.

[0035] See Figures 1 to 3 As shown, Figure 1 FIG. 1 shows a schematic diagram of the three-dimensional structure of an inflatable bed in an embodiment of the present application. Figure 2 A schematic diagram of the assembly of a mattress in one embodiment of the present application is shown. This embodiment of the present application provides a mattress, specifically an inflatable mattress, comprising a cushion layer 1, a filling layer 3, and a cover layer 2 arranged in sequence along a first direction F1. The cover layer 2 is connected to the cushion layer 1 along the first direction F1 and defines an installation cavity between the cover layer 2 and the cushion layer 1. The filling layer 3 is accommodated in the installation cavity.

[0036] In the embodiment of the present application, the filling layer 3 is configured to be able to expand and contract along the first direction F1 under the action of pressure, so as to cushion the contact area between the user and the mattress, increase the contact area between the human body and the mattress, thereby improving the user's comfort and experience.

[0037] The filling layer 3 is made of a flexible material with a certain degree of elasticity, specifically any one of sponge and silicone foam. When the filling layer 3 is made of a sponge material, the sponge material can be selected from any one or more of polyurethane foam, slow-rebound sponge (memory foam), high-density sponge, recycled sponge, natural latex sponge, silicone foam, bio-based sponge, and air fiber to meet the needs of different users and the production requirements of different product types.

[0038] Furthermore, in some embodiments, the cushion layer 1 includes a first connection portion 11 arranged circumferentially along the cushion layer 1, the first connection portion 11 encloses a first connection area, and a plurality of first connection points 12 are arranged at intervals in the first connection area, which can be arranged in an array on the surface of the cushion layer 1.

[0039] Similarly, the cover layer 2 includes a second connection portion 21 arranged circumferentially along the cover layer 2. The second connection portion 21 encloses a second connection area, and a plurality of second connection points 22 are arranged at intervals in the second connection area. The second connection points 22 are also arranged in an array on the surface of the cover layer 2.

[0040] Continue reading Figure 2As shown, specifically, along the first direction F1, the second connection portion 21 is correspondingly connected to the first connection portion 11, thereby enabling a closed installation cavity to be formed between the cushion layer 1 and the cover layer 2. The second connection points 22 are arranged in a one-to-one correspondence with the first connection points 12. In addition, the filling layer 3 is also provided with a plurality of connection channels 31. The connection channels 31 are arranged in an array on the filling layer 3 and are arranged in a one-to-one correspondence with the first connection points 12 and / or the second connection points 22. The connection channels 31 extend along the first direction F1 and penetrate the filling layer 3.

[0041] During actual assembly, along the first direction F1, the first connection points 12 and the second connection points 22 can be correspondingly connected through the connection channels 31, thereby achieving multi-point connection between the cover layer 2 and the cushion layer 1. Specifically, the cover layer 2 and the cushion layer 1 can be stably connected by a hot pressing process.

[0042] During the actual processing process, the cover layer 2 and the cushion layer 1 are connected together through the connecting channel 31 hollowed out on the filling layer 3. The filling layer 3 does not need to be divided into fragmented structures before being filled into the installation cavity. Instead, it is filled into the installation cavity as a whole and then fixed through the connection of multiple groups of first connection points 12 and second connection points 22. This greatly reduces the processing steps and saves human resources, effectively improving production efficiency.

[0043] In this embodiment, the filling layer 3 forms weld points at the connection channels 31, connecting the first connection points 12 and the second connection points 22. This creates a pleasing mattress shape after the cover layer 2 and cushion layer 1 are assembled and hot-pressed. Furthermore, depending on the size and distribution of the connection channels 31, the mattress surface can be formed into a six-, five-, or four-point unit shape, further enhancing the mattress's aesthetics.

[0044] During actual production, the operator can design the connecting channel 31 of a specified size and a specified position on the filling layer 3 according to production requirements, and this is not limited in the embodiment of the present application.

[0045] Specifically, the above-mentioned connection method can, on the one hand, increase the connection area between the cover layer 2 and the cushion layer 1, thereby improving the overall connection stability of the mattress; on the other hand, the connection between the first connection point 12 and the second connection point 22 also plays a limiting role on the filling layer 3, so that the filling layer 3 is stably placed in the installation cavity and will not move significantly after being squeezed by external force, thereby effectively preventing the filling layer 3 from shifting or running off after long-term use, thereby ensuring the comfort of use of the mattress; on the other hand, the provision of multiple connection channels 31 can effectively reduce the volume of the filling layer 3 in the installation cavity, thereby reducing the overall weight and storage volume of the mattress, and improving the portability of the mattress.

[0046] Continue reading Figure 1 As shown, in some embodiments, the first connecting portion 11 and the second connecting portion 21 are arranged along the periphery of the cushion layer 1 and the periphery of the cover layer 2, respectively, to ensure that the installation cavity formed between the cushion layer 1 and the cover layer 2 after connection has as large a volume as possible, so that under the premise of a certain overall volume of the mattress, more filling layers 3 can be filled in the installation cavity, thereby improving the comfort of use of the mattress.

[0047] In other embodiments, although the first connecting portion 11 and the second connecting portion 21 are also arranged along the circumferences of the cushion layer 1 and the cover layer 2, respectively, there is still a certain distance between the outer edge of the first connecting portion 11 and the outer edge of the cushion layer 1. Similarly, there is also a certain distance between the outer edge of the second connecting portion 21 and the outer edge of the cover layer 2. After the cover layer 2 is assembled onto the cushion layer 1, a certain gap is left between the outer edges of the outermost connecting portions of the cushion layer 1 and the cover layer 2. This effectively prevents loosening or cracking of the connection points at the outer edges of the mattress, thereby ensuring the overall connection stability of the mattress.

[0048] In some other embodiments, in order to further improve the overall connection stability of the mattress, after the cover layer 2 and the cushion layer 1 are connected by means of a hot pressing process, a circle of stitches (not shown) can be added on the outside of the connection position to further prevent the connection position of the mattress from loosening, thereby improving the quality of the finished mattress.

[0049] See Figures 1 to 3 As shown, Figure 3 A schematic diagram of the mattress assembly in another embodiment of the present application is shown. To further enhance the mattress's comfort, wear-resistant and waterproof fabrics are typically used to make the cushion layer 1 and cover layer 2. The cushion layer 1 and cover layer 2 are connected using a hot pressing process to ensure a sealed installation cavity formed between the cushion layer 1 and cover layer 2.

[0050] In an embodiment of the present application, the mattress also includes a mattress air nozzle 4 installed on the cover layer 2 and / or the cushion layer 1. After production is completed, gas can be filled into the installation cavity through the mattress air nozzle 4 to fill the interior of the installation cavity, thereby further improving the softness and comfort of the mattress, and thus optimizing the user experience.

[0051] In addition, the filling layer 3 is made of sponge material. Based on the rebound effect of the sponge itself, the user can use the rebound of the sponge to achieve automatic inflation when using it, so as to accelerate the inflation speed when the user uses it for camping and improve the convenience of use.

[0052] See Figure 1 and Figure 2As shown, in some embodiments, along the first direction F1, the projection of the filling layer 3 on the reference plane V1 can basically cover the projection of the cushion layer 1 on the reference plane V1, that is, the filling layer 3 can fill the entire installation cavity as much as possible, and the filling layer 3 is installed in the entire bed part to ensure the user's comfort.

[0053] See Figure 1 and Figure 3 As shown, in some other embodiments, along the first direction F1, the projection of the filling layer 3 on the reference plane V1 can only cover part of the projection of the cushion layer 1 on the reference plane V1, that is, the filling layer 3 is only filled in the part that mainly contacts the human body, and the remaining part relies entirely on gas filling. This can not only ensure the user's comfort, but also ensure the lightweight of the product, further reduce the weight of the mattress and the volume of the mattress after storage, and improve the portability of the mattress.

[0054] Combine Figures 1 to 3 As shown, in some embodiments, the present application further provides an inflatable bed, which includes a mattress as shown in any of the above embodiments, and a headrest 5 that can be installed on the mattress. Specifically, an air cavity is provided inside the headrest 5, which can be connected to the installation cavity of the mattress, so that the headrest 5 can be inflated synchronously with the installation cavity by means of the mattress air nozzle 4.

[0055] In addition, in some embodiments, the air cavity inside the headrest 5 is connected to the mounting cavity, and the headrest 5 also includes a headrest air nozzle (not shown), wherein the headrest air nozzle adopts a two-layer design, and the first layer is provided with a one-way valve, which is used to release the air in the headrest outward and block external air from entering the air cavity and the mounting cavity through the headrest air nozzle, so as to avoid the automatic expansion of the filling layer 3 during the storage process and affect the storage speed and effect. The setting of the one-way valve is conducive to achieving a fast winding operation; the second layer is provided with a quick air release port, so that the air inside the headrest 5 and the mounting cavity can be discharged with the help of the quick air release port to accelerate the winding process.

[0056] In addition, before using the inflatable bed, the user can inflate the air cavity and the mounting cavity through the mattress air nozzle 4 to speed up the inflation process. In the embodiment of the present application, inflation can be achieved by the rebound of the filling layer 3 or by the user blowing air.

[0057] In other embodiments, the air cavity within the headrest 5 is isolated from the mounting cavity, and the headrest 5 is detachably mounted to the mattress. That is, the headrest 5 and the mattress are independent of each other, allowing the user to adaptively adjust the position of the headrest 5 according to actual needs, thereby improving the user experience.

[0058] In the embodiment of the present application, the headrest 5 also includes a headrest air nozzle. Before using the inflatable bed, the headrest air nozzle and the mattress air nozzle 4 can be used to inflate the air cavity and the mounting cavity respectively. The inflation of the mounting cavity can be achieved by the rebound of the filling layer 3.

[0059] In some other embodiments, the airbed further includes an inflation device that can be detachably connected to the headrest air nozzle or the mattress air nozzle 4 to achieve inflation. In the present embodiment, the inflation device can be any of a variety of inflation devices, such as an electric air pump, a manual air pump, or a foot-operated air pump, and also has an air replenishment function, thereby ensuring that the airbed is always fully inflated and ensuring user comfort.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
