[0046] Reference Figures 1 to 8 The following are several embodiments of the multifunctional sofa of this utility model.

[0047] like Figures 1 to 4 As shown, the multifunctional sofa of this utility model embodiment includes a sofa body 100, an air purifier 200, and sensory components. The interior of the sofa body 100 forms an installation space 110, and the sofa body 100 is provided with an air outlet 133, which communicates with the installation space 110. The air purifier 200 is disposed in the installation space 110. The air purifier 200 includes a purification unit 210 and an air outlet pipe 220. The purification unit 210 is connected to the air outlet 133 through the air outlet pipe 220. The sensory components are disposed on the sofa body 100. The sensory components include one or more of an odor generator 310, a sound player 320, and a light source 330.

[0048] The air purification unit 210 purifies the air in the environment where the multifunctional sofa is located. The purified air flows out through the air outlet 220 and the air outlet 133. The air outlet 220 guides the purified air, reducing the probability of the purified air being polluted inside the sofa body 100. The air purifier 200 is installed in the installation space 110 inside the sofa body 100, which can make full use of the internal space of the sofa body 100 and is conducive to the miniaturization of the multifunctional sofa. The sensory components are used to enrich the user's sensory experience and improve user satisfaction.

[0049] The air purification unit 210 is installed within the installation space 110, making full use of the internal space of the multi-functional sofa. The exhaust pipe 220 guides the purified air to the exhaust port 133, reducing the probability of the purified air being contaminated by the environment inside the installation space 110. If the purified air is directly discharged into the installation space 110, it is easily subject to secondary pollution as it flows through the installation space 110 to the exhaust port 133, reducing the quality of the gas emitted by the multi-functional sofa. Without the exhaust pipe 220, the air purification unit 210 would need to be placed close to the exhaust port 133, affecting the internal layout of the installation space 110 and making it impossible to guarantee that all the purified air will flow out through the exhaust port 133.

[0050] The air purification unit 210 has air outlet pipes 220 on both opposite sides, and the sofa body 100 has corresponding air outlets 133 on both opposite sides, allowing the air purified by the air purification unit 210 to flow out from the opposite sides of the sofa body 100. In this embodiment, the air outlets 133 are located on the left and right sides of the sofa body 100. The air outlet pipes 220 allow purified air to be delivered to the air outlets 133 without requiring the air purification unit 210 to be placed close to them, facilitating the layout within the installation space 110.

[0051] In some embodiments, such as Figure 2 As shown, the sofa body 100 includes a seat 120 and two armrest walls 130. The seat 120 connects to the two armrest walls 130, and an installation space 110 is formed between the two armrest walls 130 and the seat 120. The purification unit 210 is provided with an air inlet 211. That is to say, air can enter the installation space 110 from the bottom, front and rear sides of the sofa body 100, and enter the purification unit 210 through the air inlet 211.

[0052] In other embodiments, the sofa body 100 can be a box, and air inlets can be provided at the bottom and back of the sofa body 100. The gas entering the installation space 110 through the air inlets enters the purification host 210 through the air inlet 211. The air inside the purification host 210 is purified by the purification host 210 and flows to the outside of the multifunctional sofa through the air outlet 220 and the air outlet 133. The air inlet 211 is provided at the bottom and side of the purification host 210, so that the air inlet 211 and the air inlet correspond one-to-one.

[0053] In some embodiments, the air purification unit 210 includes a housing and a dehumidifier and a filter located inside the housing; wherein, the air outlet pipe 220 is connected to the housing; a negative ion generator is provided at the air outlet 133; the dehumidifier dehumidifies the air inside the air purification unit 210, and the dehumidified air is filtered by the filter; the negative ion generator can generate negative ions, which help to adsorb small particulate matter in the filtered air to improve air quality; the air treated by the negative ion generator is discharged from the air outlet 133.

[0054] like Figure 7 and Figure 8 As shown, the air inlet 211 is connected to the housing, and the housing is provided with a connection port that is connected to the air outlet 220. The air inlet 211 is located on the side of the filter screen away from the connection port, and the dehumidifier is located between the air inlet 211 and the filter screen.

[0055] The filters include high-efficiency HEPA filters and activated carbon filters; HEPA filters are mainly used to filter particulate matter in the air, such as dust, pollen, smoke, and bacteria; activated carbon filters are used to adsorb harmful gases, odors, and volatile organic compounds (VOCs) in the air; negative ion generators can produce negative ions, which help to adsorb tiny particulate matter in the air, making it heavier, so that it settles to the ground or is captured by the filter.

[0056] Generally, dehumidifiers are semiconductor dehumidifiers, which are a new type of dehumidifier that uses semiconductor refrigeration to dehumidify. Semiconductor dehumidifiers are existing technology, and the embodiments of this utility model will not be described in detail here.

[0057] The air purification unit 210 may also include a fan, which is located inside the housing. The fan is used to drive the airflow inside the housing, so that air enters the housing through the air inlet 211 and is discharged through the air outlet 220.

[0058] like Figure 4 As shown, the seat 120 provides space for the user to sit. The seat 120 includes a frame 121 and a seat cushion 122, with the cushion 122 mounted on the frame 121. The cushion 122 enhances comfort, while the frame 121 provides support. Armrests 131 are mounted on the armrest wall 130, providing a support point to help the user maintain balance more easily when sitting or standing. The mounting space 110 is located at the bottom of the seat cushion 122.

[0059] In some embodiments, such as Figure 2 As shown, the air outlet 133 is located on the armrest wall 130; the armrest wall 130 is close to the user's nasal cavity, which is more conducive to delivering fresh air to the user; an air sensor 132 is provided on the armrest wall 130, and the air sensor 132 is located adjacent to the air outlet 133, which is conducive to timely detection of the air around the sofa and the air discharged from the air outlet 133; the air sensor 132 is electrically connected to the air purification unit 210 so as to adjust the operating parameters of the air purification unit 210 according to the air conditions detected by the air sensor 132.

[0060] In some embodiments, such as Figure 2 As shown, the sofa body 100 also includes a backrest 140; the armrest walls 130 are provided with side support portions 134, and the backrest 140 is located between the side support portions 134 of the two armrest walls 130. When the user sits on the seat 120, the backrest 140 can provide support for the user's back, avoiding back fatigue or discomfort caused by sitting for a long time; when the user sits on the seat 120, the user's side arm can rest on the side support portion 134, providing the user with more support points and improving comfort.

[0061] In some embodiments, such as Figure 2 As shown, a multifunctional sofa also includes a voice recognizer 410, which is located on the side of the side armrest 134 facing the backrest 140. When the user sits on the seat 120, the distance between the side armrest 134 and the user's head is very small. This arrangement makes it convenient for the voice recognizer 410 to receive the user's voice and recognize the user's voice information.

[0062] The voice recognition device 410 includes a voice recognition chip and a microphone. A microphone is a device that converts sound signals into electrical signals. The microphone collects the user's voice signals and transmits the collected voice signals to the voice recognition chip. The voice recognition chip processes the voice signals, converts them into control commands, and sends them to the corresponding actuators.

[0063] In some embodiments, such as Figure 2 As shown, the sensory component includes an odor generator 310, which is mounted on the top of the side armrest 134, so that the user can receive the olfactory sensation brought by the odor generator 310 when leaning on the backrest 140 or the side armrest 134.

[0064] Among them, the scent generator 310 can be an aromatherapy box, which is equipped with an atomizer to atomize and release essential oils. It can diffuse the essential oil components throughout the space in a short time, bringing a faster fragrance effect and improving the indoor environment. It can release different scents according to the user's preferences.

[0065] In some embodiments, such as Figure 2 As shown, a multifunctional sofa also includes a humidifier 420. The humidifier 420 increases the moisture in the air, preventing it from becoming too dry and maintaining a humid environment. Furthermore, the humidifier 420 helps reduce static electricity and decreases the amount of suspended dust in the air, thereby improving indoor air quality. The humidifier 420 is installed on the top of the side armrest 134, effectively utilizing vertical space and avoiding encroachment on the space on the armrest 131 seat 120. The humidifier 420 is a device already in the art; for example, it includes a water tank, an ultrasonic vibrator, a fan, and a misting nozzle, which will not be described in detail here.

[0066] In some embodiments, such as Figure 4 As shown, a multifunctional sofa also includes a control panel 500, which is connected to the purification unit 210. The control panel 500 can control the opening and closing of the purification unit 210.

[0067] In some embodiments, the control board 500 is equipped with an AI chip and a WiFi module. The AI ​​chip is equipped with a deep learning algorithm framework 121, which continuously optimizes the control strategy by learning and analyzing a large amount of user data. The AI ​​chip connects to the Internet via the Wi-Fi module to communicate with the smart home cloud platform. Users can remotely control various functions of the sofa through a mobile APP, and receive software upgrade pushes to continuously improve the intelligence level of the sofa.

[0068] Users can switch between scene modes (such as "reading mode" and "sleep mode") via voice commands, or set various operating parameters of the multi-functional sofa through a mobile app and remote control. It can automatically adjust various functional modules based on AI algorithms and environmental parameters to optimize the user experience; it can also analyze data collected by air sensors in real time to predict user needs; and it can record user habits and optimize operating parameters accordingly. For example, it can automatically activate a soft light mode and release soothing fragrances at night.

[0069] In some embodiments, such as Figure 4 As shown, the sensory component includes a sound player 320, which is located at the upper end of the backrest 140. When the user's back is against the backrest 140, the upper end of the backrest 140 is close to the user's head. This arrangement facilitates the transmission of sound emitted by the sound player 320 to the user. The sound player 320 is located on the side of the backrest 140 facing the side armrest 134.

[0070] In some embodiments, the sound player 320 can be a bone conduction speaker, a device that transmits sound through the principle of bone conduction. Unlike traditional speakers, bone conduction speakers do not transmit sound through the air, but rather transmit sound vibrations directly to the user's bones (e.g., the skull). The sound is conducted to the inner ear through the bones, without needing to pass through the ear canal, thus providing less interference to the ear canal. The bone conduction speaker can also be mounted on the armrest 131.

[0071] The audio player 320 is electrically connected to the control board 500. The control board 500 connects to smart devices via Bluetooth or Wi-Fi and controls the bone conduction speakers to play audio content. Simultaneously, the control board 500 utilizes speech synthesis technology to convert the sofa's operating status and prompts into voice signals, which are then played to the user through the bone conduction speakers.

[0072] In some embodiments, such as Figure 2 and Figure 3As shown, a multifunctional sofa also includes a temperature control component 700, which includes a heating element and a surface temperature sensor; the sofa body 100 includes a backrest 140 and a leg pad 150, and the seat 120 connects the backrest 140 and the leg pad 150; the backrest 140, the seat 120 and the leg pad 150 are respectively provided with the temperature control component 700.

[0073] The heating element can increase the surface temperature of the backrest 140, seat 120, and leg rest 150, providing heat therapy to the user's head, neck, waist, and legs. A surface temperature sensor can monitor the temperature of the seat 120, backrest 140, and leg rest 150 in real time, and adjust the operating parameters of the heating element accordingly based on the data detected by the surface temperature sensor.

[0074] The heating element and the surface temperature sensor are electrically connected to the control board 500. The control board 500 monitors the temperature in real time through the surface temperature sensor. Based on the difference between the set temperature and the actual temperature, the control board 500 controls the working state of the heating element to achieve heat therapy for the user's head, neck, waist and legs.

[0075] The heating element is a graphene heating element, which is a heating device that utilizes the electrothermal properties of graphene to generate heat. Graphene has very high thermal conductivity, enabling it to rapidly convert electrical energy into heat energy, allowing for quick heating to reach the predetermined temperature. The surface of the graphene heating element can evenly distribute heat, providing a more uniform heating effect and avoiding localized overheating or uneven temperature distribution. Due to graphene's high electrical and thermal conductivity, the graphene heating element can efficiently convert electrical energy into heat energy during operation, reducing energy loss and thus exhibiting high energy efficiency.

[0076] In some embodiments, such as Figure 5 and Figure 6As shown, the multifunctional sofa also includes an adjustment assembly 800, which includes an electric actuator 810 and a telescopic link 820. The electric actuator 810 is fixed to the frame 121, and the backrest 140 is rotatably connected to the frame 121. The telescopic link 820 includes a first rod and a second rod arranged in a cross configuration, and the first rod and the second rod are rotatably connected. The backrest 140 is rotatably connected to one end of the telescopic link 820, and the leg cushion 150 is rotatably connected to the other end of the telescopic link 820. The extension shaft of the electric actuator 810 is connected to the telescopic link 820. When the push rod 810 is working, the extension shaft of the electric push rod 810 extends, the first rod and the second rod rotate relative to each other, and the telescopic connecting rod 820 extends, so that the leg pad 150 extends out of the seat 120. At the same time, the backrest 140 rotates relative to the seat 120 to allow the user to lie flat. When the electric push rod 810 is working, the extension shaft of the electric push rod 810 retracts, the first rod and the second rod rotate relative to each other, and the telescopic connecting rod 820 shortens, so that the leg pad 150 retracts to the bottom of the seat 120. At the same time, the backrest 140 rotates relative to the seat 120 to allow the user to sit upright.

[0077] When a user sits on the multi-functional sofa, the system automatically enters a scenario mode (such as "reading mode" or "sleep mode"). The electric actuator 810 operates, causing the backrest 140, seat 120, and leg rest 150 to adjust to a suitable position according to the preset program to fit different parts of the user's body. In reading mode, the heating element starts heating to provide heat to the neck and waist. In sleep mode, the bone conduction speaker plays sleep-aiding music, and the scent generator 310 releases sleep-aiding aromatherapy.

[0078] In some embodiments, such as Figure 4 As shown, the sensory component also includes a light source 330, which is strip-shaped. The strip-shaped light source 330 can provide a uniform lighting effect, thereby creating a unique atmosphere and effect. Generally, the light source 330 is a light strip.

[0079] In some embodiments, such as Figure 4 As shown, the light source 330 is located at the bottom of the sofa body 100, which can provide soft background light, create a warm and comfortable atmosphere, avoid glaring light, and make the whole environment look more relaxing and tranquil, making it suitable for use as lighting in leisure spaces.

[0080] In some embodiments, the light source 330 is positioned on the backrest 140 to avoid excessively glaring light and enhance overall comfort; through the reflection of light, the room's spatial sense becomes more layered.

[0081] The light source 330 can be an adjustable RGB light strip, which is a light strip composed of red, green, and blue LED beads. It can be controlled using a digital control chip, achieving brightness adjustment through PWM dimming technology and color adjustment through RGB color mixing technology. Users can set the lighting via a mobile app or a control panel on the sofa.

[0082] In some embodiments, the sofa body 100 is equipped with a light intensity and color sensor, which is used to detect the intensity and color temperature of ambient light.
