Description

Technical Field

[0001] The utility model relates to a sofa, in particular to a multi - cavity portable mobile sofa. Background Art

[0002] With the continuous improvement of people's living standards, people have higher and higher requirements for furniture, especially sofas. They not only hope that it has good comfort, but also expect it to have the characteristics of being easy to move, carry and being multi - functional. As a commonly used furniture in daily life, although the traditional design and manufacturing methods can meet the needs of household use, there are obvious defects in terms of portability and adaptability to multi - scenario use. Especially in occasions such as outdoor activities and exhibitions where temporary rest areas need to be arranged, the disadvantages of traditional sofas become particularly prominent.

[0003] First of all, most of the existing sofas adopt wooden or metal frames with sponge fillers. Such materials determine that the weight of the sofas is generally heavy, making handling and moving extremely inconvenient. In outdoor environments or exhibition venues, the arrangement and later storage of sofas often require the cooperation of multiple people, which is time - consuming and laborious, increasing the labor and time costs. In addition, the fixed structure of traditional sofas determines that they cannot be compressed, resulting in a large transportation space being occupied during handling. Therefore, large transportation tools usually need to be used for transportation, and if not careful during transportation, the surface or frame part of the sofa may be bumped and damaged, shortening its service life.

[0004] Secondly, the design of traditional sofas cannot meet the needs of users for flexibility and diverse scenarios. In outdoor, exhibition and other environments, sofas need to be both light and strong, and at the same time can be quickly deployed and stored. Most of the existing sofas in the prior art do not have this flexibility. Their heavy volume and weight make it difficult for users to carry and place the sofas independently. Even some portable sofas often sacrifice comfort and durability, and it is difficult to provide sufficient support and comfort during use, unable to meet the needs of long - term use.

[0005] Although the prior art has also tried to use inflatable structures to achieve the functions of portable sofas, these inflatable sofas often have poor stability due to unreasonable structural design, the inflation or deflation process is cumbersome, and the service life is short, unable to meet the dual needs of users for comfort and practicality. In addition, the overall support of the inflatable structure is not strong, and it is prone to deformation during use, unable to maintain a comfortable use experience for a long time. Therefore, it is necessary to make further improvements to it. Summary of the Utility Model

[0024] The following further describes the present utility model in detail with reference to the drawings. A multi-cavity portable mobile sofa includes a seat body 1 and a backrest body 2 spliced by multiple airtight materials. The seat body 1 and the backrest body 2 are arranged in an "L" shape, and the interiors of both are hollow to form a first inflatable cavity 3. The first inflatable cavity 3 is connected to a first inflating nozzle 31. A number of tension blocks 32 are arranged inside the first inflatable cavity 3, and the peripheries of the tension blocks 32 are connected to the inner surface of the first inflatable cavity 3, serving to connect the opposite surfaces of the seat body 1 and the backrest body 2;

[0025] It further includes a seat pressure regulating body 4 arranged on the surface of the seat body 1. The interior of the seat pressure regulating body 4 is hollow to form a second inflatable cavity 41, and the second inflatable cavity 41 is connected to a second inflating nozzle 42;

[0026] It further includes a backrest pressure regulating body 5 arranged on the surface of the backrest body 2. The interior of the backrest pressure regulating body 5 is hollow to form a third inflatable cavity 51, and the third inflatable cavity 51 is connected to a third inflating nozzle 52.

[0027] In one embodiment, a concave deformation cavity 6 is provided in the middle of the seat body 1 and the backrest body 2.

[0028] In one embodiment, the first inflation nozzle 31, the second inflation nozzle 42, and the third inflation nozzle 52 are disposed on the back surface of the backrest body 2. The second inflation nozzle 42 and the third inflation nozzle 52 are communicated with the seat cushion pressure regulating body 4 and the backrest pressure regulating body 5 respectively through an air tube 9 passing through the first inflation cavity 3.

[0029] In one embodiment, the airtight materials are hermetically connected by sewing threads.

[0030] In one embodiment, the airtight material is PVC coated fabric.

[0031] In one embodiment, an anti-slip layer 7 is provided at the bottom of the seat cushion body 1.

[0032] In one embodiment, a plurality of left and right hanging ears 8 are provided on the side of the seat cushion body 1.

[0033] In one embodiment, a sofa cover is sleeved on the surfaces of the seat cushion body 1 and the backrest body 2.

[0034] Working principle: The sofa of the present utility model is made of airtight materials and is internally designed with a plurality of inflation cavities, including a first inflation cavity formed by the hollow of the seat cushion body and the backrest body, and second and third inflation cavities formed in the seat cushion pressure regulating body and the backrest pressure regulating body. When in use, the user inflates each cavity through the inflation nozzle. Due to the reasonable design of the inflation cavities of the sofa, sufficient internal air pressure can be provided after inflation, enabling the sofa to have a solid support structure.

[0035] During the inflation process, the tensioning blocks provided inside the first inflation cavity play a role in connecting the opposite surfaces of the seat cushion body and the backrest body. The presence of the tensioning blocks prevents the inflation cavity from expanding or deforming in structure due to uneven internal air pressure or excessive pressure. Through the stretching and supporting effects, the tensioning blocks ensure the stability of the seat cushion body and the backrest body, avoiding overall deformation or collapse due to excessive air pressure after inflation.

[0036] Among them, it should be emphasized that: the seat cushion pressure regulating body and the backrest pressure regulating body of the sofa achieve independent inflation and adjustment through the second inflation cavity and the third inflation cavity respectively. The user can, according to actual needs, adjust the pressure of the seat cushion and the backrest respectively through the second inflation nozzle and the third inflation nozzle to adjust the comfort level. This independent pressure adjustment design allows the user to flexibly control the softness and hardness of each part, thereby achieving a personalized usage experience.

[0037] In addition, by reasonably arranging the air tubes, the second inflation cavity and the third inflation cavity can be connected through the first inflation cavity, making the overall structure of the sofa more compact during inflation. At the same time, since the inflation nozzle is disposed on the back surface of the backrest body, the inflation process is more convenient, without affecting the overall aesthetics and usage comfort of the sofa.

[0038] When not in use, the user can open the inflation valve to quickly deflate. After the gas in the sofa is discharged, the entire sofa can be easily folded and stored. Due to the use of airtight materials and a hollow inflation structure, the space occupied by the sofa after folding is very small, making it convenient to carry and store, and is especially suitable for outdoor activities or temporary occasions.

[0039] Compared with traditional technologies, the inflation structure of the present utility model greatly reduces the weight of the sofa. When not in use, it can be folded into a small volume, which is convenient to carry and move, and is very suitable for scenarios that require frequent movement such as outdoors and exhibitions. Compared with traditional bulky sofas, users can carry it alone without the need for additional tools or equipment.

[0040] In addition, through the multi-chamber design and the supporting effect of the tension rib blocks, the present utility model has good supporting force in the inflated state, ensuring that the sofa will not deform or collapse due to inflation. At the same time, the independent inflation pressure regulation design allows users to perform personalized adjustment on the seat cushion and backrest parts, enhancing the comfort of the sofa.

[0041] At the same time, the multi-chamber design and the tension rib block support of the present utility model ensure the overall stability of the sofa. Especially when bearing the weight of the human body, it can evenly distribute the pressure and prevent local deformation. After inflation, the structure of the sofa is firm and reliable, avoiding the common problems of instability or rapid air leakage during the use of inflatable sofas. Due to the use of airtight materials and the inflatable design, the sofa can be quickly deflated and folded after use, greatly reducing the storage space. This not only reduces the complexity of transportation but also reduces the transportation cost, without the need for large transportation equipment and additional packaging materials, greatly improving the convenience of transportation and storage.

[0042] In summary, through a reasonable multi-chamber design, an independent pressure regulation function, and a lightweight inflation structure, the present utility model has successfully solved the problems of existing sofas being difficult to carry, transport, and having poor comfort. It has many technical advantages such as being portable, comfortable, stable, and durable, so it can be widely promoted and used.
