Description

Technical Field

[0001] The utility model belongs to the technical field of mattresses, and in particular relates to a sponge mattress core and a sponge mattress adapted for an electric bed. Background Art

[0002] Existing foam mattresses suitable for electric beds often use a single piece of foam. When placed on an electric bed, the foam mattress bends with the bed's base, creating a loose fit between the mattress and the bed, creating a large gap at the bend interface and a poor user experience. A single piece of foam cannot provide both comfort and support.

[0003] In the prior art, some solutions use two sponges with different hardness, but the thickness of the two sponges is consistent everywhere, and the compatibility with the electric bed is still poor. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing electric bed sponge mattresses, which lack both comfort and support. It provides a sponge mattress core compatible with electric beds. By combining two sponges of different hardness and distributing their thicknesses according to the dimensions of the electric bed's bending interface, the sponge mattress core improves its bending compatibility with the electric bed.

[0012] As an improvement, the intersection position where the thickness of the first sponge layer and the second sponge layer changes corresponds to the bending intersection area of ​​the electric bed, which is beneficial to the bending of the bed core.

[0013] As an improvement, the first sponge layer and / or the second sponge layer are provided with deformation grooves in the thickness direction. The upper and lower surfaces of the bed core are pressed to drive the deformation grooves to deform, so that the bed core fits the human body better.

[0014] As an improvement, each deformation groove is provided at a concave-convex portion of the first sponge layer or the second sponge layer.

[0015] As an improvement, the cross section of the deformation groove is smaller at the outer end and larger at the inner end.

[0016] As an improvement, the deformation groove includes a lollipop-shaped groove and / or a clothes-drying-fork-shaped groove.

[0035] The technical solutions of the embodiments of the present invention are explained and described below, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0036] See also Figures 1 to 4 The sponge mattress core adapted for an electric bed according to an embodiment of the present invention comprises:

[0037] First sponge layer;

[0038] Second sponge layer;

[0039] Wherein, the first sponge layer and the second sponge layer have different hardnesses;

[0040] wherein the first sponge layer and the second sponge layer are fixedly connected;

[0041] The first sponge layer and the second sponge layer have different thicknesses along the head and tail directions of the electric bed and have corresponding concave and convex portions.

[0042] The sponge mattress core adapted for an electric bed of the present invention includes two sponge layers of different hardness, forming different soft and hard surfaces. The two sponge layers are fixedly connected and have different thicknesses along the head and tail directions of the electric bed, and the concave and convex shapes correspond to each other, which can improve the adaptability of the sponge mattress core to the electric bed when it is bent. Compared with a bed core made of a single high-hardness sponge, the mattress of the present invention is easier to bend, has a better fit with the electric bed, and is softer and more comfortable. Compared with a bed core made of a single low-hardness sponge, the bed core of the present invention has better support. Compared with a bed core made of two sponge layers of different hardness with a constant thickness, the bed core of the present invention achieves a better balance between support, softness and comfort, and ease of bending.

[0043] Example 1

[0044] See also Figures 1 to 4 The sponge mattress core 01 adapted for the electric bed 03 of the first embodiment of the present invention comprises:

[0045] First sponge layer 1;

[0046] Second sponge layer 2;

[0047] Wherein, the first sponge layer 1 and the second sponge layer 2 are stacked;

[0048] The first sponge layer 1 and the second sponge layer 2 have different hardnesses;

[0049] Wherein, the first sponge layer 1 and the second sponge layer 2 are fixedly connected;

[0050] The first sponge layer 1 and the second sponge layer 2 have different thicknesses along the head-to-tail direction of the electric bed 03 and have corresponding concave and convex portions.

[0051] In this embodiment, the first sponge layer 1 is a low-hardness memory foam, and the second sponge layer 2 is an extra-hard sponge. The first sponge layer 1 is positioned above the second sponge layer 2. The extra-hard sponge at the bottom ensures support strength, while the memory foam at the top ensures softness and comfort. The softer sponge layer is typically placed on top during use, but the mattress core can also be turned upside down. In other embodiments, the harder sponge layer can also be placed on top.

[0052] In this embodiment, the intersection where the thickness of the first and second sponge layers 1 and 2 varies corresponds to the bending region of the electric bed 03. At this intersection, the softer memory foam is thicker, while the harder, extra-hard foam is thinner, making the bed core easier to bend.

[0053] In this embodiment, the first sponge layer 1 and the second sponge layer 2 have four thickness variation locations along the length direction, that is, the direction from the head to the foot of the bed. The thickness of the first sponge layer 1 is consistent in the same width direction; the thickness of the second sponge layer 2 is consistent in the same width direction. The first sponge layer 1 and the second sponge layer 2 each have two convex portions 12 or concave portions 22, forming four thickness variation locations. The lower surface of the first sponge layer 1 has two downward convex portions 12, and the upper surface of the second sponge layer 2 has two concave portions 22. Figure 4 It can be seen that the electric bed 03 has three bending points. Among them, although the length of the protruding area between the two recessed parts 22 of the second sponge layer 2 is relatively small, it can still provide good support.

[0054] In this embodiment, the first sponge layer 1 includes a first base 11 and two protrusions 12, and the second sponge layer 2 includes a second base 21 and two recesses 22. The thickness of the first base 11 of the first sponge layer 1, which has a lower hardness, is less than the thickness of the second base 21 of the second sponge layer 2, which has a higher hardness. The thickness of the protrusions 12 is the same as the depth of the recesses 22.

[0055] In this embodiment, both the first and second sponge layers 1 and 2 have deformation grooves 3 extending through their thickness. Pressure on the upper and lower surfaces of the mattress core causes these grooves 3 to deform, further facilitating the core's bending and ensuring a better fit for the body. The inner ends of the deformation grooves 3 are not continuous.

[0056] In this embodiment, each deformation groove 3 is provided in the convex portion 12 of the first sponge layer 1 or the concave portion 22 of the second sponge layer 2 .

[0057] In this embodiment, the cross section of the deformation groove 3 is smaller at the outer end and larger at the inner end. The deformation groove 3 is in a shape of larger inner end and smaller outer end, which is not only conducive to the bending of the bed core, but also makes the bed core compact after bending.

[0058] In this embodiment, the deformation groove 3 includes a lollipop-shaped groove 31 and a clothes-drying-fork-shaped groove 32. In other embodiments, the shape, size, distribution, etc. of the deformation groove 3 may also be changed accordingly.

[0059] In this embodiment, the first sponge layer 1 and the second sponge layer 2 are bonded together.

[0060] In this embodiment, the thickness of the sponge mattress core 01 is uniform at all locations, that is, the upper surface and the lower surface of the core are substantially flush when not bent.

[0061] In this embodiment, during the processing, the first sponge layer 1 (ungrooved) and the second sponge layer 2 (ungrooved) are first processed, then the first sponge layer 1 and the second sponge layer 2 are glued and stacked, and finally the deformation groove 3 is cut on the first sponge layer 1 and the second sponge layer 2.

[0062] The beneficial effects of the sponge mattress core 01 of the first embodiment of the present invention are as follows: the bed core comprises two first sponge layers 1 and second sponge layers 2 of different hardness, the harder second sponge layer 2 at the bottom ensures support strength, and the softer first sponge layer 1 at the top ensures softness and comfort; the thicknesses of the first sponge layer 1 and the second sponge layer 2 along the head and tail directions of the electric bed 03 are different and the concave and convex portions correspond, the thinner area of ​​the second sponge layer 2 corresponds to the bending position of the electric bed 03, and the bed core is easier to bend; deformation grooves 3 in the thickness direction are provided on both the first sponge layer 1 and the second sponge layer 2, and the deformation grooves 3 make the bed core easier to bend, and also make the bent bed core more fit with the electric bed 03, and can also ensure comfort; the outer end of the deformation groove 3 is small and the inner end is large, the first sponge layer 1 at the top is tighter after bending, and the second sponge layer 2 at the bottom is easier to bend.

[0063] The present invention also provides a foam mattress adapted for an electric bed 03, comprising a bed core and a quilted layer 02, wherein the bed core is the aforementioned foam mattress bed core 01 adapted for an electric bed 03. The structure of the quilted layer 02 and its connection structure with the bed core can refer to the prior art.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
