Description

Technical Field

[0001] This application relates to the field of sofas, and more particularly to a smart sofa. Background Technology

[0002] Traditional sofas typically use materials like foam, springs, or latex as filling layers. While offering some comfort, their insufficient breathability during prolonged use leads to heat buildup and moisture buildup in areas in contact with the body, resulting in stuffiness and discomfort. This is especially true in summer or high-humidity environments, where the poor heat dissipation of traditional sofas negatively impacts the user experience. Furthermore, while some sofas use breathable fabrics, they rely solely on passive ventilation, failing to effectively create airflow and thus not fundamentally solve the heat dissipation problem.

[0003] To improve the breathability of sofas, existing technologies have proposed various improvement solutions. For example, using mesh fabrics or 3D mesh fabrics as the sofa surface to enhance breathability through the material's own porous structure; or setting honeycomb support structures and ventilation channels inside the sofa cushions to promote airflow through natural convection; or installing small fans at the bottom of the sofa to cool the seat surface through external airflow. Although these solutions can improve breathability to some extent, they all have obvious limitations: breathable materials rely solely on passive heat dissipation, resulting in low air exchange efficiency; ventilation structures are easily blocked and rendered ineffective by human body pressure; and external fans suffer from problems such as unreasonable airflow direction and excessive noise.

[0029] Please refer to Figure 1 - Figure 4 One embodiment of this application provides a smart sofa 300, comprising:

[0030] The sofa body 100 includes a seating area 110 formed on the top, a fan assembly 120 disposed on the side, a plurality of air inlets 111 distributed on the surface of the seating area 110, and an airflow channel opened inside the sofa body 100.

[0031] The first end of the airflow channel is connected to the air inlet of the fan assembly 120, and the second end is connected to each air inlet 111. The fan assembly 120 is configured to form a negative pressure airflow circulation path from the surface of the seat area 110 to the fan outlet through the air inlet 111, the airflow channel and the fan assembly 120.

[0032] A sofa cushion 200 covers the surface of the seating area 110. The top surface of the sofa cushion 200 contacts the human body to form a first contact surface 210, and the bottom surface adheres to the surface of the seating area 110 to form a second contact surface 220.

[0033] Furthermore, the structural design of the sofa body 100 achieves efficient ventilation through the coordinated operation of the top seating area 110, the side fan assembly 120, the surface air inlets 111, and the internal airflow channels. The evenly distributed air inlets 111 on the surface of the seating area 110 are directly connected to the internal airflow channels. The two ends of the airflow channels precisely align with the air inlets of the fan assembly 120 and each air inlet 111, creating a complete negative pressure airflow circulation system. The negative pressure generated by the fan assembly 120 is transmitted through the airflow channels to each air inlet 111, creating a uniform suction effect on the surface of the seating area 110, ensuring the coverage and continuity of airflow. The double-layer design of the sofa cushion 200 ensures comfort while maintaining the airtightness of the airflow channels by ensuring a close fit between its bottom surface and the seating area 110, preventing air leakage. The core advantages of this structural design are: by accurately calculating the cross-sectional area of ​​the airflow channel and the distribution density of the air inlet 111, the airflow resistance is optimized; the position of the fan assembly 120 takes into account both noise isolation and suction efficiency; the overall layout achieves the maximum ventilation effect with minimal space occupation; and the positional relationship of each component has been verified by fluid dynamics simulation to ensure the optimization of the airflow path.

[0034] In one specific embodiment, the sofa cushion 200 includes a leather layer 201 and a combed cotton layer 202. The outer surface of the leather layer 201 forms a first contact surface 210, and the combed cotton layer 202 is laminated to the lower surface of the leather layer 201 and forms a second contact surface 220 with the surface of the seating area 110.

[0035] The first contact surface 210 is provided with a matrix of heat dissipation holes 211, which penetrate the skin layer 201 and extend into the carding layer 202, forming a continuous airflow permeation channel from the first contact surface 210 through the carding layer 202 to the air inlet hole 111.

[0036] Furthermore, the surface of the leather layer 201 is equipped with a precisely calculated matrix of heat dissipation holes 211. The diameter, spacing, and arrangement angle of these holes are optimized by hydrodynamics to ensure uniform airflow without affecting seating comfort. The heat dissipation hole group 211 adopts a conical design, with a structure that is smaller at the top and larger at the bottom, which prevents foreign objects from entering and reduces airflow resistance. The carded layer 202 adopts a three-dimensional mesh structure, with its fiber density varying gradually from the upper to the lower layers, ensuring both support and high breathability. The two layers are bonded at the molecular level through a hot-pressing process, forming microscopic airflow channels at the contact surface. The innovation of this composite structure lies in: achieving a balance between breathability and durability through precise matching of material properties; the layered density gradient design that disperses pressure while maintaining smooth airflow; and a special interface treatment process that ensures no interlayer separation occurs during long-term use while maintaining stable breathability. The thickness ratio, pore size ratio, and density ratio of each layer have all been rigorously tested to determine the optimal parameter combination.

[0037] In one specific embodiment, the sofa body 100 has a first accommodating cavity 141 and a second accommodating cavity 142 on both sides along the length direction, and the fan assembly 120 is detachably installed in the first accommodating cavity 141 and the second accommodating cavity 142 by fasteners.

[0038] Furthermore, the first and second accommodating cavities 141 and 142 are precisely symmetrically distributed on both sides of the sofa body 100 along its length. Their internal spatial shapes are specifically designed according to the fan's shape, including detailed structures such as positioning slots, shock-absorbing pads, and wire channels. The opening direction of the accommodating cavities is ergonomically calculated, facilitating operation while preventing foreign objects from entering. The fan assembly 120 achieves quick assembly and disassembly using special fasteners; the number and location of the fastening points are mechanically analyzed to ensure stability. The innovation of this installation structure is reflected in: the dual-cavity design achieving fan load balancing and redundancy backup; the special anti-vibration structure controlling noise below 40 decibels; and the maintenance channel design considering the needs of all possible maintenance scenarios. Each accommodating cavity is equipped with an independent temperature control monitoring point and a dust filter to ensure long-term stable operation. The internal airflow guiding structure optimizes air intake efficiency and reduces turbulence generation.

[0039] In one specific embodiment, the axes of the first accommodating cavity 141 and the second accommodating cavity 142 are mirror-symmetrically distributed with respect to the central axis of the width direction of the sofa body 100, and the opening directions of the two accommodating cavities are both facing outwards from the sofa.

[0040] Furthermore, the spatial relationship between the two cavities follows a strict principle of symmetry. The central axes of the two cavities form a precise mirror image symmetry with the central axis of the sofa body 100. This symmetry is reflected not only in the planar position but also in parameters such as height and tilt angle in three-dimensional space. The opening direction of the cavities is designed to tilt outward at a 15-degree angle, a specific angle verified by CFD simulation as the optimal air intake angle. The curved surface of the guide vanes inside the cavities has undergone hundreds of iterations of optimization to ensure smooth airflow into the fans. The advantages of this symmetrical system are: the completely symmetrical layout eliminates the problem of unbalanced loading on one side of the fan; the precisely calculated opening angle maximizes air intake efficiency; and the optimized design of the internal curved surfaces minimizes airflow loss. The dimensional tolerance of every detail is controlled within ±0.5mm, ensuring that the operating parameters of the two fans are highly consistent. The system also features an automatic balancing adjustment function, which monitors and adjusts the speed difference between the two fans in real time.

[0041] In one specific embodiment, the sofa cushion 200 further includes a heating pad 203 disposed between the leather layer 201 and the combed cotton layer 202. The heating pad 203 is fixed to the lower surface of the leather layer 201 by a hot melt adhesive layer, and the heating area of ​​the heating pad 203 is offset from the distribution area of ​​the heat dissipation hole group 211.

[0042] Furthermore, the integrated design of the heating system achieves perfect synergy between temperature regulation and ventilation functions. The heating pad 203 is made of graphene composite material, and its heating area is precisely planned to maintain a specific safe distance from the heat dissipation hole group 211. The thickness of the hot melt adhesive layer is controlled within the range of 0.3-0.5mm, ensuring both thermal conductivity and sufficient elasticity. A temperature sensor is embedded between the heating pad 203 and the carding layer 202 to monitor the contact surface temperature in real time. The innovations of this integrated system are: the algorithm for arranging irregularly shaped heating areas ensures uniform temperature distribution; the intelligent temperature control system automatically adjusts the power according to the ambient temperature and humidity; and the special interlayer structure design prevents heat from diffusing to unintended areas. The system can raise the contact surface temperature to the set value within 1 minute while ensuring that the temperature of the surrounding area does not exceed the safe threshold. The collaborative control algorithm of the heating element and the ventilation system ensures optimal comfort under any operating conditions.

[0043] In one specific embodiment, the bottom of the sofa body 100 is provided with a forward-extending third receiving cavity 151, and the third receiving cavity 151 is provided with a pull-out tray, and the surface of the tray is provided with an elastic buckle assembly for fixing shoes.

[0044] Furthermore, the bottom storage system incorporates several engineering innovations. The third storage chamber 151 utilizes a high-strength aluminum alloy frame structure, and its slide rail system has undergone 100,000 opening and closing tests. The tray's surface texture is treated with an anti-slip finish, and the elastic buckles are made of memory metal, adapting to different sizes of shoes. The structural advantages of the storage system are reflected in: a special angle design that ensures smooth, jam-free pulling; a shock-absorbing structure that prevents items from making noise when used on the sofa; and a concealed guide rail design that is both aesthetically pleasing and dustproof. Every mechanical component of the system undergoes surface hardening treatment to ensure it will not wear out over long-term use. Space utilization reaches over 85% while maintaining sufficient structural strength.

[0045] In one specific embodiment, the back of the sofa body 100 is provided with a fourth receiving cavity 161, and a wireless speaker module is embedded in the fourth receiving cavity 161. The wireless speaker module is connected to an external terminal via Bluetooth protocol, and its sound emission direction is towards the front of the seating area 110.

[0046] Furthermore, the acoustic structure of the fourth cavity has been professionally tuned, featuring an optimal combination of reflective surfaces and sound-absorbing materials. The installation angle of the speaker module has been precisely calculated to ensure the optimal sound wave propagation path. Wireless connectivity utilizes the latest Bluetooth 5.2 protocol, ensuring stable and latency-free transmission.

[0047] In one specific embodiment, the sofa body 100 has a fifth receiving cavity 171 on both side walls. A spare sofa cushion set wrapped in a dust cover is placed in the fifth receiving cavity 171, and a magnetic cover is provided at the opening of the fifth receiving cavity 171.

[0048] Furthermore, the inner wall of the fifth receiving chamber 171 is made of antibacterial material, and the dust cover uses nano-level breathable and waterproof fabric. The magnetic cover's opening and closing mechanism has undergone 5000 durability tests, and the magnetic strength has been precisely calculated. The innovations of this storage system include: a special moisture-proof design to ensure no deformation during long-term storage; an intelligent reminder function that automatically prompts when replacement is needed; and a compact structural design that allows for large-capacity storage without affecting the appearance. The system is also equipped with RFID identification, which can automatically identify the stored sofa cushion model 200 and usage records.

[0049] In one specific embodiment, the surface of the first contact surface 210 is coated with a waterproof coating, and its surface is provided with a micropore array corresponding to the heat dissipation hole group 211.

[0050] Furthermore, the surface treatment technology achieves a perfect balance between waterproofing and breathability. The arrangement of the microporous array follows fractal geometry principles, ensuring an optimal breathability-to-waterproof ratio. Precise pore size control ensures that breathability is not compromised; special surface textures enhance tactile comfort.

[0051] In one specific embodiment, the sofa body 100 adopts a main frame structure formed by integral stamping of cold-rolled steel plate, and the surface of the main frame structure is covered with a foam filling layer.

[0052] Furthermore, the stamping process of the cold-rolled steel sheet adopts the latest hydroforming technology, and the stress distribution of the frame structure has been optimized through finite element analysis. The density gradient of the foam filling layer is precisely controlled to achieve the best balance between support and comfort.

[0053] Therefore, the smart sofa 300 of this application integrates the fan assembly 120 into the side of the sofa body 100 and connects it with the internal airflow channel and the air inlet 111 on the surface of the seating area 110, thus constructing a directional airflow circulation system of "human contact surface, air inlet 111, airflow channel, and fan". Its active negative pressure suction significantly improves heat dissipation efficiency and solves the problem of poor passive ventilation; while the even distribution of the air inlet 111 ensures that the airflow covers the entire contact surface and avoids local blockage; and the integrated structural design ensures both heat dissipation effect and space utilization. In particular, the optimized layout of the airflow channel and the fan assembly 120 achieves efficient and quiet airflow circulation, perfectly overcoming the defects of existing technologies such as loud noise from external fans and unreasonable airflow direction.

[0054] The embodiments described above are merely examples of several implementations of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application.
