Abstract
Description
Technical Field
[0001] This utility model relates to furniture technology, and more specifically, to a mattress with adjustable firmness. Background Technology
[0002] A mattress is a piece of furniture that sits between the human body and the bed frame. When subjected to pressure from the human body, a mattress can deform relatively, providing support while conforming well to the curves of the body, thus providing a comfortable lying environment.
[0003] Different people have different needs for mattress firmness when sleeping. For example, people with lumbar muscle strain are more suitable for using a firmer mattress to provide better support for their lower back when lying down, while people who are thin are more suitable for a softer mattress to distribute the pressure on their bones and joints when lying down.
[0004] However, most existing mattresses have a fixed firmness, which makes them less adaptable to different users.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mattress with adjustable firmness.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mattress with adjustable firmness, comprising a contact layer, an adjustment layer and a support layer that are detachably connected from top to bottom. The adjustment layer has a pillow cavity and several body cavities. The pillow cavity and body cavities are arranged along the width direction of the adjustment layer. The adjustment layer also has a buffer cavity located below all the body cavities. The bottom surface of the body cavity has a circular hole that connects to the buffer cavity. The adjustment layer has an air tube connecting to the buffer cavity and an air tube connecting to the pillow cavity.
[0008] The present invention is further configured such that: the adjustment layer is provided with an annular cavity along the edge of the adjustment layer, the annular cavity surrounds the buffer cavity, the occipital cavity and all body cavities, and the adjustment layer is provided with an inflation tube connecting the annular cavity.
[0009] The present invention is further configured such that: the bottom surface of the adjustment layer is provided with a plurality of hook and loop surfaces, the contact layer is provided with a plurality of connecting strips, and the connecting strips are provided with hook and loop hook surfaces for matching the hook and loop surfaces.
[0010] The present invention is further configured such that the area of the hook and loop surface is larger than the area of a single hook and loop hook surface.
[0011] The present invention is further configured such that: the contact layer has a plurality of friction points on the side wall facing the adjustment layer.
[0012] The present invention is further configured such that: the support layer is provided with a surrounding frame for abutting against the outer peripheral wall of the adjustment layer.
[0013] The present invention is further configured such that the height of the enclosure frame is less than half the thickness of the contact layer.
[0014] In summary, this utility model has the following beneficial effects:
[0015] Before using the mattress, users can inflate the body cavity and the pillow cavity separately through air tube one and air tube two. By adjusting the amount of air flowing through air tubes one and two, the firmness of the body cavity and the pillow cavity can be adjusted. This design allows users to adjust the pillow area and body area of the mattress separately, making the mattress suitable for a wider range of people. Since people usually lie along the length of the mattress, the unpressurized parts of the body cavity will bulge when local pressure is applied. By setting the body cavity along the width of the adjustment layer, the bulge of the body cavity is less likely to affect the adjustment layer's fit to the body's curves. When people lie on the mattress, the cushioning cavity can effectively disperse the concentrated pressure, reducing the problem of excessive deformation of the adjustment layer in some areas due to pressure concentration. In addition, placing the cushioning cavity below the body cavity makes it less likely to affect the adjustment layer's fit to the body's curves. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] A mattress with adjustable firmness, such as Figure 1As shown, the mattress includes a contact layer 1, an adjustment layer 2, and a support layer 3, which are detachably connected from top to bottom. The contact layer 1 is used to directly conform to the body. The support layer 3 contains several mattress springs. The adjustment layer 2 has one pillow cavity 4 and several body cavities 5, which are arranged along the width of the adjustment layer 2. The adjustment layer 2 also has a buffer cavity 6 located below all the body cavities 5. The bottom surface of each body cavity 5 has a circular hole 7 connecting to the buffer cavity 6. The adjustment layer 2 has an air tube 8 connecting to the buffer cavity 6 and an air tube 9 connecting to the pillow cavity 4. Before using the mattress, people can... The body cavity 5 and the occipital cavity 4 are inflated respectively through air tube 8 and air tube 9. The firmness of the body cavity 5 and the occipital cavity 4 is adjusted by regulating the amount of air flowing through air tubes 8 and 9. This design allows for zoned adjustment of the occipital area and the body area of the mattress, making it suitable for a wider range of people. Since people usually lie along the length of the mattress, the unpressurized parts of the body cavity 5 will bulge when localized pressure is applied. By arranging the body cavity 5 along the width of the adjustment layer 2, the bulges in the body cavity 5 are less likely to conform to the adjustment layer 2. The body's curves are affected. When people lie on the mattress, the cushioning cavity 6 can effectively disperse the concentrated pressure, reducing the problem of excessive deformation in some areas of the adjustment layer 2 due to pressure concentration. When a certain body cavity 5 is compressed, causing excessive gas to be squeezed out, this gas can enter the cushioning cavity 6 through the round hole 7 or enter other body cavities 5 through the cushioning cavity 6, reducing the possibility of the body cavity 5 bursting due to excessive pressure. In addition, the cushioning cavity 6 is located below the body cavity 5, so that the cushioning cavity 6 does not easily affect the fit of the adjustment layer 2 to the body's curves. The adjustment layer 2 also has a feature along the adjustment layer. The annular cavity 10 is set at the edge of the mattress. The annular cavity 10 surrounds the cushioning cavity 6, the pillow cavity 4 and all the body cavities 5. The adjustment layer 2 is provided with an inflation tube 3 11 connected to the annular cavity 10. Before using the mattress, the annular cavity 10 needs to be inflated through the inflation tube 3 11. The setting of the annular cavity 10 can reinforce the edge of the mattress and prevent the adjustment layer 2 from collapsing when people sit on the edge of the mattress, making it easier for people to get up. The annular cavity 10 is controlled independently of the body cavity 5 and the pillow cavity 4, so that people are less likely to affect the annular cavity 10 when adjusting the body cavity 5 and the pillow cavity 4.
[0022] like Figure 2 and Figure 3As shown, the bottom surface of the adjustment layer 2 is attached with several hook and loop fasteners 12, and the contact layer 1 is sewn with several connecting straps 14 arranged circumferentially along the contact layer 1. Each connecting strap 14 has a hook and loop fastener 13 sewn onto it to match the hook and loop fasteners 12. The connecting straps 14 are made of elastic fabric. When assembling the mattress, after adjusting the adjustment layer 2, the contact layer 1 is placed on the adjustment layer 2. Then, the connecting straps 14 are wrapped around the outer wall of the adjustment layer 2, and the hook and loop fasteners 13 are fitted onto the hook and loop fasteners 12, completing the connection between the contact layer 1 and the adjustment layer 2. This design prevents relative movement between the contact layer 1 and the adjustment layer 2 when people are lying on the bed. The area of the hook and loop fasteners 12 is larger than the area of a single hook and loop fastener 13. This design requires excessive time to align the hook and loop fasteners 13 with the loop fasteners 12 when fitting the hook and loop fasteners 13 onto the loop fasteners 12. Furthermore, with the loop fasteners 12 positioned on the bottom surface of the adjustment layer 2, the portion of the loop fasteners 12 not mates with the hook and loop fasteners 13 directly contacts the upper surface of the support layer 3. Since the loop fasteners 12 are softer than the hook and loop fasteners 13, this design effectively prevents damage to the upper surface of the support layer 3. Several friction points are attached to the sidewall of the contact layer 1 facing the adjustment layer 2. Specifically, these friction points are made of rubber material. Using this material increases the maximum static friction between the contact layer 1 and the adjustment layer 2, further preventing the possibility of relative sliding between them.
[0023] like Figure 1 and Figure 2 As shown, a surrounding frame 15 for abutting the outer perimeter of the adjustment layer 2 is fixed on the support layer 3. Specifically, a surrounding frame 15 made of wooden board material is fixed around the support layer 3. When assembling this mattress, the interconnected contact layer 1 and adjustment layer 2 are placed on the support layer 3, and the surrounding frame 15 completely surrounds the support layer 3, making it difficult for the adjustment layer 2 to move relative to the support layer 3 in the horizontal direction. The height of the surrounding frame 15 is less than half the thickness of the contact layer 1. This setting ensures that when people do not fill the body cavity 5, pillow cavity 4 and cushion cavity 6 with air, the contact layer 1 and adjustment layer 2 will not be completely submerged in the surrounding frame 15 when the human body presses on the contact layer 1 and adjustment layer 2, thus preventing the surrounding frame 15 from being exposed on the top surface of the mattress.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
