Description

Technical Field

[0001] This invention relates to the field of pillow devices, specifically to a smart, sleep-aiding, and anti-snoring multifunctional pillow and its preparation method. Background Technology

[0002] Snoring is a common problem in modern society, not only affecting the sleep of others but also potentially a sign of sleep apnea syndrome, which is related to one's own health. However, traditional coping methods such as medication or devices are often uncomfortable and have low compliance. While professional medical devices such as medical ventilators are effective, they can cause discomfort when worn, resulting in a poor user experience. Therefore, anti-snoring pillows have emerged.

[0003] Existing anti-snoring pillows have a delayed intervention mechanism. The system only activates after snoring persists and exceeds a preset threshold. This means that the intervention only occurs passively after the user's airway is already obstructed and snoring is produced, making it impossible to prevent snoring beforehand. Secondly, the intervention method is too harsh. Regardless of the user's sleeping position, vibration warnings are used, lacking precise recognition and guidance of sleeping posture, resulting in limited effectiveness. This externally imposed vibration stimulation will inevitably interfere with the sleep process and may cause sleep interruption. Although it stops snoring, it damages the integrity and depth of sleep, violating the original intention of improving sleep quality. Summary of the Invention

[0019] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings: Example 1: The present invention provides a smart sleep aid and anti-snoring multifunctional pillow, including a pillow body 1, wherein the pillow body 1 is provided with at least one adjustable airbag assembly for supporting the head; A sound acquisition module is integrated on the pillow body 1 for directional acquisition of the user's snoring. The sound acquisition module is connected to a signal processing unit, which has a built-in noise reduction algorithm to filter out ambient noise. Pressure sensors: Several pressure sensors are installed in the adjustable airbag assembly to collect and detect the position of the user's head resting on the pillow and the real-time direction of movement. An air pump control module is connected to the pillow body 1. The air pump control module is connected to the adjustable airbag group through a pipeline. The air pump control module adjusts the inflation volume of the corresponding airbag 2 in real time according to the head position signal collected by the pressure sensor and the snoring signal collected by the sound acquisition module, so as to change the head tilt angle and left and right twist angle. A physiological signal acquisition module is integrated on the pillow body 1. The physiological signal acquisition module is used to collect and record the user's heart rate and respiratory rate data.

[0020] During use, the built-in sound acquisition module and pressure sensor collect the user's snoring and head position signals. Then, the main control module analyzes the signals. If snoring is detected, an adjustment plan is calculated based on the head position. Subsequently, the air pump control module drives the corresponding airbag 2 to inflate or deflate, thereby relieving snoring by changing the head tilt angle or left and right rotation angle. The entire process records heart rate and respiratory rate data simultaneously for subsequent sleep quality assessment.

[0021] The sound acquisition module is used to directionally acquire the user's snoring and output the snoring frequency characteristic value H and snoring loudness L. When the snoring frequency characteristic value is within the range of 200Hz≤H≤400Hz and the snoring loudness L>50dB, the air pump control module controls the corresponding airbag 2 to gently adjust with a first inflation volume P1=0.02MPa. When the snoring frequency characteristic value H>400Hz and the snoring loudness L>65dB, indicating that the snoring is sharp and loud, the air pump control module controls the corresponding airbag 2 to inflate with a second inflation volume P2=0.05MPa for a larger amplitude adjustment. The pressure sensor monitors the user's head placement position and movement direction in real time. When the pressure sensor detects the head... When the body continues to deviate to one side for more than the time threshold t=10 seconds, the air pump control module performs gradient pressure adjustment on the corresponding side airbag 2. The adjustment range is divided into three levels according to the deviation distance d. When the deviation distance d < 2 cm, fine adjustment compensation is performed. When d is between 2 and 4 cm, medium amplitude adjustment is performed. When d > 4 cm, maximum amplitude adjustment is performed. The physiological signal acquisition module monitors the user's heart rate R and respiratory rate B in real time. When the heart rate R exceeds the threshold of 85 beats / minute or the respiratory rate B exceeds the threshold of 25 beats / minute, it is determined that the user is in a state of light sleep or about to wake up. The air pump control module will simultaneously activate the micro-vibration assistance function to help the user smoothly transition to the deep sleep stage.

[0022] Example 2: In conjunction with the technical solution of Embodiment 1, this technical solution further includes a main control module on the pillow body 1. The main control module is electrically connected to the signal processing unit, the air pump control module, and the physiological signal acquisition module. Based on real-time data of snoring, heart rate, and respiratory rate, the main control module comprehensively determines the sleep stage to assess sleep quality. Based on the aforementioned data characteristics, the system determines whether the user is currently in deep sleep, light sleep, or awake state. Based on the sleep stage determination result, the main control module dynamically assesses sleep quality and records relevant indicators.

[0023] Furthermore, the adjustable airbag assembly comprises six independently controlled airbags 2, each equipped with a pressure sensor and connected to the air pump control module. The air pump control module includes a low-noise miniature air pump and control circuitry. By adjusting the inflation volume of the six airbags 2, the air pump control module creates a height gradient on the pillow surface to guide the user's head. When in operation, the air pump control module is powered by the miniature air pump, and the control circuitry regulates the airflow connected to the six independent airbags 2. By precisely controlling the amount of air entering each airbag 2, different height zones are created on the pillow surface, gently guiding the user's head towards a more comfortable breathing posture.

[0024] Furthermore, the sound acquisition module is a directional microphone array 3, which is positioned towards the user's head area to collect sound waves from that area. The microphone array is concentrated towards the head area to pick up sound, and by processing the sound waves within this range, it accurately captures the user's snoring.

[0025] Furthermore, the physiological signal acquisition module is a piezoelectric thin-film sensor, which is laid below the adjustable airbag assembly or at the bottom of the pillow body, and is used to monitor heart rate and respiratory rate through body pressure fluctuations. By sensing changes in human body pressure through the piezoelectric thin film laid below the airbag 2 or at the bottom of the pillow, the sensor calculates the user's heart rate and respiratory rate by analyzing these subtle pressure fluctuations.

[0026] Furthermore, the pillow body 1 is also equipped with a wireless communication module, which is electrically connected to the main control module. This module is used to send the collected snoring, heart rate, and respiratory rate data, as well as sleep quality assessment results, to an external mobile terminal or cloud server. The main control module inside the pillow aggregates the collected snoring, heart rate, and respiratory rate data, and the wireless communication module automatically sends this data and sleep assessment report to the user's mobile device or cloud server, allowing the user to easily view their sleep records.

[0027] Furthermore, the surface of the pillow body 1 is covered with a memory foam layer or a latex layer, and the adjustable airbag assembly is disposed beneath the memory foam layer or latex layer. The pillow surface is a layer of memory foam or latex to provide support for the user, and the airbag assembly 2 for height adjustment is located below it, which can realize intelligent adjustment function and ensure comfort during use.

[0028] Furthermore, the air pump control module is equipped with a solenoid valve assembly on its pipeline. This assembly is connected one-to-one with each of the airbags 2 to achieve independent and precise control over the inflation and deflation of each airbag 2. The air pump generates airflow, which is precisely switched on and off via the solenoid valves individually connected to each airbag 2 in the pipeline, thereby achieving independent inflation and deflation control of specific airbags 2 and adjusting the height of different areas of the pillow.

[0029] A method for preparing a smart sleep-aiding and anti-snoring multifunctional pillow, comprising the smart sleep-aiding and anti-snoring multifunctional pillow as described in any one of claims 1-8: S1. Module prefabrication: Prepare an adjustable airbag assembly including a built-in pressure sensor, a circuit board with an integrated sound acquisition module, and a sensing pad encapsulated with a physiological signal acquisition sensor. S2. Pillow body forming and cavity opening: The memory foam pillow body with a specific support structure is formed by molding or cutting process, and a cavity and channel are preset inside it to accommodate the adjustable airbag assembly, circuit and air pipeline; S3. System integration and air circuit connection: The adjustable airbag assembly prepared in step S1 is placed into the cavity of the pillow body according to the preset layout, and it is connected to the low-noise micro air pump and solenoid valve assembly through a hose to form a complete pneumatic adjustment circuit. S4. Electrical system integration and testing: Place the circuit board and sensing pad prepared in step S1 into the corresponding positions of the pillow body, and electrically connect the air pump, solenoid valve, all sensors and main control module, and then perform power-on communication and functional testing. S5. Assembly and Packaging: After testing, the base is mechanically combined with the pillow body that integrates all modules to ensure smooth operation of the adjustment mechanism, and finally the outer pillowcase is packaged.

[0030] Two independent airbags equipped with pressure sensors, a circuit board integrating directional sound reception, and a sensor pad for monitoring heartbeat and breathing are prepared. Then, a memory foam pillow body with pre-set cavities and channels is made through molding to embed these electronic and pneumatic components. Next, the two airbags are precisely placed into the pillow body cavity and connected to a silent air pump and solenoid valve to form an air circuit system. At the same time, various sensor circuits are electrically connected to the main control module and functional tests are completed. Finally, all components are packaged and assembled with a base and pillowcase to form an intelligent anti-snoring pillow with physical adjustment and physiological monitoring functions.

[0031] Furthermore, in step S2, the pillow body is made of slow-rebound memory foam material through a single-stage foaming process using a mold. The cavities and channels are directly formed by a core pre-placed in the mold during the foaming process. By injecting the slow-rebound material into the mold with the built-in core for foaming, cavities and channels accommodating the airbags 2 and the tubing are directly molded inside the pillow body while simultaneously forming the pillow body, thus achieving one-stage molding of the pillow core structure and functional cavities.

[0032] How this application works: The internal microphone array and air pressure sensor collect the user's snoring signals and head position data in real time. Then, the main control chip analyzes this information. When continuous snoring is detected, a silent air pump is immediately activated to inflate and deflate a specific airbag 2. This adjusts the head tilt angle to relieve airway obstruction. At the same time, a piezoelectric film sensor continuously monitors heart rate and breathing rhythm. All data is used for real-time adjustment and can also be wirelessly transmitted to a mobile phone to generate a sleep report. The pillow body uses a two-layer structure of independent airbags wrapped in memory foam. During production, sensors and airways are pre-embedded in the mold through in-mold foaming, ultimately achieving an integrated anti-snoring function that combines physical adjustment and health monitoring.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
