Description

Technical Field

[0001] This utility model belongs to the field of air bed technology, specifically relating to a self-inflating sponge bed. Background Technology

[0002] There are two main types of foam beds: self-inflating foam beds and fabric-covered foam beds. Each type has its own advantages and disadvantages. Self-inflating foam beds are firm and not very comfortable when inflated, but they are small in size when deflated. Regular fabric-covered foam beds are more comfortable, but they are not convenient to store and are larger in size, making them inconvenient for outdoor use.

[0003] Existing self-inflating foam mattresses generally use ordinary foam of poor quality. Although the cost is lower, the quality is poor. After repeated use, the surface of ordinary foam is prone to irreversible deformation such as pits, which seriously affects the normal use of the foam mattress and also affects the comfort of the foam mattress.

[0004] Therefore, it is necessary to design a foam bed structure that is more resistant to deformation, can be reused more times, and is more comfortable. Utility Model Content

[0005] To address the aforementioned problems in existing technologies, this solution provides a self-inflating sponge bed.

[0006] The technical solution adopted in this utility model is as follows: A self-inflating foam bed, comprising: Inflatable base fabric; An inflatable top cover is placed on top of an inflatable bottom cover; The side wall connects the edge of the inflatable top fabric and the edge of the inflatable bottom fabric, forming an inflatable cavity between the three. At least one sponge body; when there is one sponge body, the sponge body is memory foam and is disposed in the air cavity; when there are two or more sponge bodies, one of the sponge bodies is memory foam, and the remaining sponge bodies are sponge sheets made of ordinary sponge, and at least one sponge sheet is disposed in the air cavity; the sponge sheet is a rectangular sheet structure with chamfered corners; the sponge body in the air cavity is used to expand the air cavity. An air nozzle, located on the side wall, is used for one-way ventilation of the inflation chamber to the atmosphere. When the air nozzle is closed, squeezing the sponge sheet allows air to be expelled from the inflation chamber and maintains a negative pressure state. When the air nozzle is opened, the sponge sheet returns to its original shape and allows the inflation chamber to draw air from the atmosphere to expand the inflation chamber.

[0007] Optionally: An upper reinforcing film is provided between the inflatable top fabric and the memory foam. The upper reinforcing film is a hot melt adhesive film or a TPU film. The upper reinforcing film is used to reinforce the inflatable top fabric and is fixedly connected to the memory foam in the inflation cavity; the upper edge of the side wall is fused to the edge of the inflatable top fabric.

[0008] Optional: When there is only one sponge body, if the sponge body is a regular sponge, the inflatable bottom fabric and the inflatable top fabric are directly welded together; if the sponge body is a memory foam, a lower reinforcing film is provided between the inflatable bottom fabric and the memory foam. The lower reinforcing film is a hot melt adhesive film or a TPU film. The lower reinforcing film is used to reinforce the inflatable bottom fabric and is fixedly connected to the memory foam.

[0009] Optional: When there are two sponge bodies, a sponge sheet is set below the memory foam, and the lower surface of the memory foam and the upper surface of the sponge sheet are bonded together with adhesive; an upper reinforcing film is set between the inflatable top and the memory foam, and the upper reinforcing film is a hot melt adhesive film or a TPU film.

[0010] Optionally: the upper edge of the side wall is fused to the edge of the inflatable top fabric; the lower edge of the side wall is fused to the edge of the inflatable bottom fabric.

[0011] Optionally: a memory foam is provided above the air cavity, and a wrapping layer is placed on top of the memory foam, with the edge of the wrapping layer sewn to the air top fabric.

[0012] Optional: The self-inflating foam bed cover is equipped with a removable comfort layer cover, which includes a top cover and a bottom cover, the edges of which are sewn to the sidewalls of the cover.

[0013] Optionally: the upper edge of the side wall is fused to the edge of the inflatable top fabric; the lower edge of the side wall is fused to the edge of the inflatable bottom fabric.

[0014] The beneficial effects of this utility model are as follows: This solution uses a structure of memory foam or a combination of memory foam and ordinary foam to form a self-inflating foam bed. It can make full use of the slow rebound, even pressure distribution, and reduced body reaction force of memory foam, thereby improving the comfort of the foam bed. When memory foam is combined with ordinary foam, the low cost of ordinary foam can be utilized to effectively control the cost of the foam bed. At the same time, because ordinary foam rebounds quickly, it can speed up the inflation speed of the foam bed and reduce the waiting time during use. Attached Figure Description

[0018] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0019] Example 1 like Figure 1 As shown, this embodiment designs a self-inflating sponge bed, including a wrapping layer 2, an inflatable top fabric 4, two sponge bodies, side walls 6, air nozzles 7, and an inflatable bottom fabric 8. The two sponge bodies are memory foam 3 and a sponge sheet 5.

[0020] The aforementioned self-inflating foam bed is equipped with a removable comfort layer cover, which includes a top cover and a bottom cover, the edges of which are sewn together. The top cover 1 is positioned above the memory foam 3 and also above the wrapping layer 2. The bottom cover 9 is positioned below the inflatable bottom cover 8.

[0021] Sponge sheet 5 is made of ordinary sponge, memory foam, latex foam, polyurethane foam, or other sponge materials, and has a rectangular sheet structure with chamfered edges. Sponge sheet 5 can be made from ordinary sponge.

[0022] The inflatable roof cover 4 is made of TPU material, PVC and other types of adhesive-coated fabrics, and is placed on top of the sponge sheet 5.

[0023] The inflatable base fabric 8 is made of TPU material, PVC and other various adhesive-coated fabrics, and is placed below the sponge sheet 5.

[0024] The memory foam 3 is positioned above the inflatable top fabric 4.

[0025] The wrapping layer 2 is positioned above the memory foam 3 and below the top fabric cover, with the edge of the wrapping layer 2 sewn together with the edge of the inflatable top fabric 4.

[0026] The side wall 6 is made of TPU, PVC and other adhesive-coated fabrics. The upper edge of the side wall 6 is fused together with the edge of the inflatable top fabric 4, the edge of the wrapping layer 2 and the edge of the memory foam 3. The lower edge of the side wall 6 is fused together with the edge of the inflatable bottom fabric 8.

[0027] Meanwhile, an inflation cavity is formed between the side wall 6, the inflatable top fabric 4, and the inflatable bottom fabric 8; the sponge sheet 5 is filled in the inflation cavity and used to expand the inflation cavity.

[0028] The air nozzle 7 adopts an existing valve structure with one-way ventilation. The air nozzle 7 is located on the side wall 6, and multiple air nozzles 7 can be installed to increase the airflow speed. The air nozzle 7 is used for one-way ventilation of the inflation chamber to the atmosphere; when the air nozzle 7 is closed, squeezing the sponge sheet 5 allows air to be expelled from the inflation chamber and maintains a negative pressure state; when the air nozzle 7 is open, the sponge sheet 5 returns to its original shape, allowing air to be drawn into the inflation chamber from the atmosphere to expand it.

[0029] When using the self-inflating sponge bed in this embodiment: When the foam bed needs to be folded for storage, the air in the inflation chamber can be expelled by squeezing the foam sheet 5 with external force, or the air in the inflation chamber can be extracted using a vacuum pump, thus emptying the inflation chamber and allowing the foam bed to be stored. When the foam bed needs to be unfolded for use, a tool can be used to open the air nozzle 7, allowing air from the ambient environment to smoothly enter the inflation chamber. After the compressed foam sheet 5 absorbs air, it can naturally recover, thus achieving self-inhalation, expansion, and unfolding.

[0030] Example 2 like Figure 2 As shown, this embodiment designs a self-inflating sponge bed, including components such as an inflatable top fabric 4, a sponge body, side walls 6, air nozzles 7, an inflatable bottom fabric 8, an upper reinforcing membrane 10, and a lower reinforcing membrane 11. The sponge body is memory foam 3.

[0031] Memory foam 3 has a rectangular sheet structure with chamfered edges. Memory foam 3 can be made from ordinary foam.

[0032] The inflatable top cover 4 is made of TPU material and is placed on top of the memory foam 3.

[0033] The inflatable base fabric 8 is made of TPU material and is placed under the memory foam 3.

[0034] An upper reinforcing film 10 is disposed between the inflatable top fabric 4 and the memory foam 3. The upper reinforcing film connects and reinforces the inflatable top fabric, and is also fixedly connected to the foam body inside the inflation cavity. The upper reinforcing film is made of hot melt adhesive film or TPU film to enhance the weld between the memory foam and the inflatable top fabric.

[0035] A lower reinforcing membrane 11 is disposed between the inflatable base fabric 8 and the memory foam 3. The lower reinforcing membrane connects and reinforces the inflatable base fabric, and is also fixedly connected to the foam body inside the inflation cavity. The lower reinforcing membrane is made of hot melt adhesive film or TPU film to enhance the weld between the memory foam and the inflatable base fabric.

[0036] The side wall 6 is made of TPU material, and its upper edge is directly welded to the edge of the inflatable top fabric 4. The lower edge of the side wall 6 is welded to the edge of the inflatable bottom fabric 8.

[0037] Meanwhile, an air cavity is formed between the side wall 6, the inflatable top fabric 4, and the inflatable bottom fabric 8; memory foam 3 is filled in the air cavity and used to expand the air cavity.

[0038] The air nozzle 7 adopts an existing valve structure with one-way ventilation. The air nozzle 7 is located on the side wall 6, and multiple air nozzles 7 can be installed to increase the airflow speed. The air nozzle 7 is used for one-way ventilation of the inflation chamber to the atmosphere; when the air nozzle 7 is closed, squeezing the memory foam 3 allows air to be expelled from the inflation chamber and maintains a negative pressure state; when the air nozzle 7 is open, the memory foam 3 recovers its shape and allows air to be drawn into the inflation chamber from the atmosphere to expand the inflation chamber.

[0039] When using the self-inflating sponge bed in this embodiment: When the foam bed needs to be folded for storage, the air in the inflation chamber can be expelled by squeezing the memory foam 3 with external force, or the air in the inflation chamber can be extracted using a vacuum pump, thus emptying the inflation chamber and allowing the foam bed to be stored. When the foam bed needs to be unfolded for use, a tool can be used to open the air nozzle 7, allowing air from the ambient environment to smoothly enter the inflation chamber. After absorbing air, the compressed memory foam 3 can naturally recover, thus achieving self-absorption, expansion, and unfolding.

[0040] Example 3 like Figure 3 As shown, this embodiment designs a self-inflating foam bed, including memory foam 3, inflatable top fabric 4, two foam bodies, side walls 6, air nozzles 7, inflatable bottom fabric 8, and upper reinforcing membrane 10. The two foam bodies are memory foam 3 and foam sheet 5.

[0041] Sponge sheet 5 is made of ordinary sponge and has a rectangular sheet structure, with chamfered edges at the corners. Sponge sheet 5 can be made from ordinary sponge.

[0042] The inflatable top cover 4 is made of TPU material and is placed on top of the memory foam 3.

[0043] The inflatable base fabric 8 is made of TPU material and is placed below the sponge sheet 5.

[0044] The upper reinforcing film 10 is disposed between the inflatable top fabric 4 and the memory foam 3. The upper reinforcing film 10 is a hot melt adhesive film or a TPU film to strengthen the welding between the memory foam and the inflatable top fabric.

[0045] The lower surface of memory foam 3 is bonded to the upper surface of foam sheet 5 with adhesive. Memory foam 3 can be made of a foam material with better elasticity and resilience.

[0046] The sidewall 6 is made of TPU material, and its upper edge is fused to the edge of the inflatable top fabric 4. The lower edge of the sidewall 6 is fused to the edge of the inflatable bottom fabric 8.

[0047] The side wall 6 is connected between the edge of the inflatable top fabric 4 and the edge of the inflatable bottom fabric 8, and forms an inflatable cavity between the three.

[0048] Meanwhile, an inflation cavity is formed between the side wall 6, the inflatable top fabric 4, and the inflatable bottom fabric 8; the sponge sheet 5 and the memory foam 3 are filled in the inflation cavity and used to expand the inflation cavity.

[0049] The air nozzle 7 adopts an existing valve structure with one-way ventilation. The air nozzle 7 is located on the side wall 6, and multiple air nozzles 7 can be installed to increase the airflow speed. The air nozzle 7 is used for one-way ventilation of the inflation chamber to the atmosphere; when the air nozzle 7 is closed, squeezing the sponge sheet 5 and memory foam 3 allows air to be expelled from the inflation chamber and maintains a negative pressure state; when the air nozzle 7 is open, the sponge sheet 5 and memory foam 3 recover their shape, allowing air to be drawn into the inflation chamber from the atmosphere to expand it.

[0050] When using the self-inflating sponge bed in this embodiment: When the foam bed needs to be folded for storage, the air in the inflation chamber can be expelled by squeezing the foam sheet 5 and memory foam 3 with external force, or the air in the inflation chamber can be extracted using a vacuum pump, thus emptying the inflation chamber and allowing the foam bed to be stored. When the foam bed needs to be unfolded for use, a tool can be used to open the air nozzle 7, allowing air from the ambient environment to smoothly enter the inflation chamber. After absorbing air, the compressed foam sheet 5 and memory foam 3 can naturally recover, thus achieving self-inflation, expansion, and unfolding.

[0051] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
