TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent snore-stopping pillows and breath detection, in particular to an intelligent-sensor-based height-adjustable snore-stopping pillow and a control system thereof. BACKGROUND

[0002] As a new intelligent sleep aid device, the snore-stopping pillow emerges as the times require. It integrates various sensors (such as sound sensors, vibration sensors, and pressure sensors) to monitor the sleepers' breathing status and body movements in real time and automatically adjust the height, angle, or hardness of the pillow according to the monitoring data, thereby improving the sleepers' breathing smoothness and reducing snoring.

[0003] The existing snore-stopping pillows usually use multiple independent lifting mechanisms to achieve height and angle adjustment. However, the coordination between these lifting mechanisms is poor, which may cause obvious segmental feeling during the adjustment process. This segmental feeling not only affects the user's experience and reduces the smoothness of the adjustment process, but also may interfere with the continuity of sleep and affect the user's sleep quality. On the other hand, the sound sensors of the snore-stopping pillow are usually installed inside the pillow, which may affect the detection performance of the sound sensors, such as signal attenuation or interference, and thus affect the accurate monitoring of the sleepers' breathing status. Therefore, an intelligent-sensor-based height-adjustable snore-stopping pillow and a control system thereof are proposed to solve the above problems. SUMMARY

[0012] Preferably, the method comprises the following control steps:

[0013] S1, sensor selection and pretreatment, selecting a pressure sensor as a detection device for starting the anti-snoring pillow, which will automatically start other electrical equipment to run when sensing the user's head pressure, selecting a high-sensitivity sound sensor and a vibration sensor as the main detection devices, the sound sensor is used to collect snoring sound signals, and the vibration sensor is used to detect the body vibration of the sleeper; the sound sensor and the vibration sensor need to be calibrated and pretreated in advance to ensure their accuracy and stability in the working state;

[0014] S2, signal acquisition and amplification, collecting sound signals through a sound sensor and collecting vibration signals through a vibration sensor, transmitting the collected signals to a signal amplifier, using the signal amplifier to amplify weak electrical signals, the amplification multiple is adjusted according to the signal strength, and it is ensured that the signal can be effectively processed by the subsequent device;

After adjustment, the sound and vibration signals are collected again by the sound sensor and vibration sensor, and the changes in sound and vibration intensity before and after adjustment are compared. If the snoring and vibration intensity decrease, fine adjustment is continued in the same direction; if they increase, adjustment is made in the opposite direction.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, through the structure of elastic neck support, memory foam, lifting unit, and coordinating part, the elastic neck support can support the user's neck, the memory foam can improve head comfort, the lifting unit can adjust the height and automatically adjust the angle according to the user's head contour, and the coordinating part, through the elasticity of the elastic rope, can be designed with a small displacement rope net. When the user's head is pressed down, the rope net can coordinate the adjustment of each moving head, so that there is a coordinated connection between each moving head. This coordinated effect can make the angle transition between each moving head smoother. The intelligent sensing anti-snoring pillow, together with its control system, can intelligently adjust the height of each lifting unit in order to improve the sleeper's breathing patency and comfort, and can automatically optimize the pillow's support effect according to the user's head shape, thereby improving the sleeper's overall comfort. This solves the problem that existing anti-snoring pillows have a strong sense of segmentation after height and angle adjustment, which affects comfort.

[0023] 2. In this invention, through the structure of airbags, tracheas, conduction frames, and sound sensors, the pressure of the head when using the anti-snoring pillow will compress the airbag, causing the gas inside the airbag to flow into the storage guide groove through the trachea. As the gas in the storage guide groove continues to accumulate, its internal pressure increases, pushing the support frame of the conduction frame to move upward, further driving the guide plate to rise. This pushes the sound sensor, which was originally stored in the storage guide groove, to the outside, accurately positioning it on the left and right sides of the user's head. When not in use, the tension spring will contract, pulling the support frame, guide plate, and sound sensor downward to reset, allowing the gas in the storage guide groove to flow back into the airbag through the trachea. This adjustment of the sound sensor's position ensures that it can accurately collect the user's snoring, significantly improving the accuracy of monitoring the sleeper's breathing status. Moreover, the sound sensor can be automatically retracted for protection when not in use, effectively avoiding sound signal attenuation or interference caused by the pillow material blocking it.

Several positioning grooves 102 are arranged at equal intervals on the upper side of the base plate 101. A back plate 104 is fixedly connected to the rear side of the upper end face of the base plate 101. The inner side of the back plate 104 has a... A storage guide 105 with an opening is provided. A pair of air holes 106 are provided on the front side of the storage guide 105. An elastic neck support 3 is fixedly connected to the front side of the base plate 101. Lifting units 4 are installed at each positioning slot 102. The lifting unit 4 includes a positioning plate 41 fixed inside the positioning slot 102. An electric push rod 42 is fixedly connected to the upper side of the positioning plate 41. A ball shell 43 is fixedly connected to the upper end of the drive rod of the electric push rod 42. A movable ball 44 is movably connected to the inner side of the ball shell 43. A movable head 45 is installed on the upper side of the movable ball 44.

Movable petals 455 surrounding the outer side of the base 451 are fixedly connected to the outer side of each rotating block 453. A through-hole storage channel 456 is provided on the inner side of each movable petal 455. A rope tube 457 is rotatably connected to the inner side of each storage channel 456. A cooperating part 5 is installed on the upper side of the base plate 101, located between the back plate 104 and the elastic neck support 3. The cooperating part 5 includes several angle rods 51. The corner rods 51 are all fixedly connected to the corners of the upper surface of the base plate 101. The inner side of each corner rod 51 is provided with a rope groove 52 at the same height as the rope tube 457. An elastic rope 53 is fixedly connected to the inner side of each rope groove 52. A rope net 54 is fixedly connected to the end of each elastic rope 53 away from the corner rod 51. The rope body of the rope net 54 passes through each rope tube 457. The coordinated part 5 can coordinate and communicate with each movable head 45. This coordinated action can make the angle transition between each movable head 45 smoother, effectively avoiding the segmented feeling problem that may occur in existing anti-snoring pillows due to the independent adjustment of each lifting unit 4.A memory foam 6 is installed on the upper side of the rope net 54. The memory foam 6 includes a pair of foam sheets 61 stacked vertically. The memory foam 6 can improve the comfort of the head. A pocket groove 62 is opened on the facing surface of the upper and lower foam sheets 61. Tube grooves 63 are opened on both the left and right sides of the pocket groove 62. Several mounting grooves 64 are opened on the facing surface of the upper and lower foam sheets 61, located on the left and right sides of the pocket groove 62. Vibration sensors 11 are installed inside the mounting grooves 64. A second mounting groove 65 is opened on the facing surface of the upper and lower foam sheets 61, located in front of the pocket groove 62. Pressure sensors 12 are installed on the inner side of each of the 65 components. These pressure sensors 12 can be used as detection devices to activate the anti-snoring pillow. Upon sensing pressure from the user's head, they will automatically activate other electrical devices. Pillowcases 13 are fitted over the outer sides of the base plate 101, memory foam 6, and elastic neck support 3. The device integration box 2 consists of an outer box and internal components including a signal amplifier, analog-to-digital converter, storage device, digital signal processor, response controller, and power supply. A charging interface is provided on the device integration box 2 for charging the power supply, enabling it to be used in the control system.

[0041] like Figure 4 , Figure 5 , Figures 10-12 As shown, an airbag 9 is provided inside the bladder groove 62. Air tubes 10, located inside the tube groove 63, are connected to both sides of the airbag 9. The ends of the air tubes 10 furthest from the airbag 9 are connected to air holes 106. A transmission frame 7 is provided inside the receiving guide groove 105. The transmission frame 7 includes a support frame 71 that fits against the lower inner wall of the receiving guide groove 105. A guide plate 72 is fixedly connected to the upper side of the support frame 71. Mounting holes 73 are provided on both sides of the guide plate 72. Sound sensors 8 are installed inside the mounting holes 73. A pair of tension springs 74 are fixedly connected between the lower inner wall of the receiving guide groove 105 and the lower end face of the support plate of the support frame 71. This arrangement allows for position adjustment of the sound sensors 8 to ensure their operation. It can accurately collect the user's snoring, significantly improving the accuracy of monitoring the sleeper's breathing status. When not in use, it can automatically retract the sound sensor 8 for protection, effectively avoiding sound signal attenuation or interference caused by pillow material blocking it. The support frame 71 consists of a support plate and a pair of support rods. The outer end face of the support plate of the support frame 71 is in contact with the inner wall of the storage guide groove 105. This setting can prevent gas leakage. The support plate of the support frame 71 is located on the upper side of the air hole 106. This setting allows the gas entering the storage guide groove 105 to push the support frame 71 upward. The sound sensors 8 are all located on the back side of the pillowcase 13. This setting allows the sound sensors 8 to be exposed upward without being interfered with by the pillowcase 13.

[0042] A control system includes the following control steps:

[0043] S1. Sensor Selection and Preprocessing: Pressure sensor 12 is selected as the detection device to activate the anti-snoring pillow. It will automatically start other electrical devices when it senses the pressure on the user's head. High-sensitivity sound sensor 8 and vibration sensor 11 are selected as the main detection devices. Sound sensor 8 is used to collect snoring signals, and vibration sensor 11 is used to detect the body vibration of the sleeper. Sound sensor 8 and vibration sensor 11 need to be calibrated and preprocessed in advance to ensure their accuracy and stability in working condition.

[0044] S2. Signal Acquisition and Amplification: Sound signals are acquired through sound sensor 8 and vibration signals are acquired through vibration sensor 11. The acquired signals are transmitted to a signal amplifier, which amplifies the weak electrical signals. The amplification factor is adjusted according to the signal strength to ensure that the signals can be effectively processed by subsequent equipment.

[0045] S3, Analog-to-Digital Conversion and Signal Storage: The amplified analog signal is converted into a digital signal through an analog-to-digital converter with an accuracy of 16 bits or higher. The converted digital signal is then stored in a storage device, which can be an internal Flash memory or an external SD card, for subsequent signal processing and data analysis.

[0046] S4. Signal processing and feature extraction: Digital signals are processed using a digital signal processor, including filtering and denoising. Bandpass filters are used for filtering, with a frequency range of 50-300Hz. Adaptive filters or wavelet transforms are used for denoising. Feature extraction is performed on the processed signals. Extraction methods include Fourier transform (FFT) and Mel-frequency cepstral coefficients (MFCC). Simultaneously, the intensity, frequency, and periodicity features of the vibration signal are extracted.

[0047] S5. Sound recognition and judgment: Using a pre-trained machine learning model, such as a convolutional neural network, the extracted features are classified to determine whether it is snoring. The model is stored in the storage device. The recognition time is real-time processing. Based on the sound and vibration features, it is determined whether snoring is detected. If snoring is detected, the sound intensity and feature information are recorded.

[0048] S6. Pillow adjustment and feedback: Based on the sound recognition results, the pillow height or angle is adjusted by the response controller. The adjustment method is to control the electric push rods 42 of each lifting unit 4 to extend and retract to different degrees. After adjustment, the sound sensor 8 and vibration sensor 11 collect sound and vibration signals again and compare the changes in sound and vibration intensity before and after adjustment. If the snoring and vibration intensity decrease, continue to fine-tune in the same direction; if they increase, adjust in the opposite direction.

[0049] S7. Effect evaluation and optimization: Repeat step S6 until the snoring and vibration intensity reach the lowest level or meet the preset threshold. Evaluate the adjustment effect. If the best adjustment effect is achieved, stop the adjustment. If the best effect is not achieved, continue to fine-tune and optimize the adjustment strategy to improve the sleeper's breathing patency and comfort.

[0050] S8. Data recording and user feedback: Records sound data, vibration data, adjustment parameters, and effect evaluation results throughout the process in a storage device for subsequent analysis and user feedback.

[0051] Workflow: The lifting and lowering operation of the intelligent sensing anti-snoring pillow and the sound acquisition operation of the sound sensor 8 are as follows. Note 1: For the intelligent control of the anti-snoring pillow, please refer to the section above, "A control system, including the following control steps:"; Note 2: "User" and "sleeper" are general terms; When the user uses the anti-snoring pillow, the pressure on their head will compress the airbag 9, causing the gas inside the airbag 9 to flow into the storage guide groove 105 through the air tubes 10 and air holes 106 on both sides. As the gas continuously accumulates in the storage guide groove 105, its internal pressure increases, pushing the support frame 71 of the conduction frame 7 to move upwards. This movement further drives the guide plate 72 to rise, thereby causing the sound originally stored in the storage guide groove 105 to be released. The sound sensor 8 is pushed to the outside and precisely positioned on the left and right sides of the user's head. When not in use, the tension spring 74 retracts, pulling the support frame 71, guide plate 72, mounting hole 73, and sound sensor 8 downwards to reset, allowing the gas in the storage guide groove 105 to flow back into the airbag 9 through the air tube 10. This positional adjustment of the sound sensor 8 ensures that it can accurately collect the user's snoring, significantly improving the accuracy of monitoring the sleeper's breathing status. Furthermore, the sound sensor 8 can automatically retract for protection when not in use, effectively avoiding sound signal attenuation or interference caused by pillow material obstruction. When the user's head rests on the anti-snoring pillow, the various lifting units 4 of the anti-snoring pillow are activated via the spherical shell 4. The inclusion of the movable ball 44 and the movable head 45 allows for flexible angle adjustment. When the user's head presses down, each movable head 45 automatically adjusts its angle according to the actual force applied. Simultaneously, the movable flaps 455 on each movable head 45 rotate elastically via the telescopic spring 454, also automatically adjusting their angle according to the actual force applied, thus further adapting to and conforming to the user's head contour. On the other hand, the coordinating part 5 of the anti-snoring pillow, through the elastic action of the elastic rope 53, features a rope net 54 designed for slight displacement. When the user's head presses down, the rope net 54 can coordinately adjust the movable heads 45 of each lifting unit 4, ensuring proper alignment between the movable heads 45. This collaborative mechanism creates a smoother transition between the angles of the various moving heads 45°, effectively avoiding the segmented feeling that may occur in existing anti-snoring pillows due to the independent adjustment of each lifting unit 4. Through this design, the anti-snoring pillow not only improves user comfort during use but also enables the intelligent sensing anti-snoring pillow, in conjunction with its control system, to intelligently adjust the height of each lifting unit 4 to improve the sleeper's breathing patency and comfort. It can also automatically optimize the pillow's support effect based on the user's head shape, thereby improving the sleeper's overall comfort and solving the problem of strong segmented feeling after height and angle adjustment in existing anti-snoring pillows, which affects comfort.

7. A control system for the height-adjustable anti-snoring pillow based on intelligent sensing as described in claims 1-6, characterized in that, The following control steps are included: S1. Sensor selection and preprocessing: Select pressure sensor (12) as the detection device to start the anti-snoring pillow. It will automatically start other electrical devices when it senses the pressure on the user's head. Select high-sensitivity sound sensor (8) and vibration sensor (11) as the main detection devices. Sound sensor (8) is used to collect snoring signals, and vibration sensor (11) is used to detect the body vibration of the sleeper. Sound sensor (8) and vibration sensor (11) need to be calibrated and preprocessed in advance to ensure their accuracy and stability in working condition. S2. Signal acquisition and amplification: Acquire sound signals through sound sensor (8) and vibration signals through vibration sensor (11). Transmit the acquired signals to the signal amplifier. Use the signal amplifier to amplify the weak electrical signals. The amplification factor is adjusted according to the signal strength to ensure that the signal can be effectively processed by subsequent equipment. S3, Analog-to-Digital Conversion and Signal Storage: The amplified analog signal is converted into a digital signal through an analog-to-digital converter with an accuracy of 16 bits or higher. The converted digital signal is then stored in a storage device, which can be an internal Flash memory or an external SD card, for subsequent signal processing and data analysis. S4. Signal processing and feature extraction: Digital signals are processed using a digital signal processor, including filtering and denoising. Bandpass filters are used for filtering, with a frequency range of 50-300Hz. Adaptive filters or wavelet transforms are used for denoising. Feature extraction is performed on the processed signals. Extraction methods include Fourier transform (FFT) and Mel-frequency cepstral coefficients (MFCC). Simultaneously, the intensity, frequency, and periodicity features of the vibration signal are extracted. S5. Sound recognition and judgment: Using a pre-trained machine learning model, such as a convolutional neural network, the extracted features are classified to determine whether it is snoring. The model is stored in the storage device. The recognition time is real-time processing. Based on the sound and vibration features, it is determined whether snoring is detected. If snoring is detected, the sound intensity and feature information are recorded. S6. Pillow adjustment and feedback: Based on the sound recognition results, the height or angle of the pillow is adjusted by the response controller. The adjustment method is to control the electric push rod (42) of each lifting unit (4) to extend and retract to different degrees. After adjustment, the sound sensor (8) and vibration sensor (11) are used to collect sound and vibration signals again and compare the changes in sound and vibration intensity before and after adjustment. If the snoring and vibration intensity decrease, continue to fine-tune in the same direction; if they increase, adjust in the opposite direction. S7. Effect evaluation and optimization: Repeat step S6 until the snoring and vibration intensity reach the lowest level or meet the preset threshold. Evaluate the adjustment effect. If the best adjustment effect is achieved, stop the adjustment. If the best effect is not achieved, continue to fine-tune and optimize the adjustment strategy to improve the sleeper's breathing patency and comfort. S8. Data recording and user feedback: Records sound data, vibration data, adjustment parameters, and effect evaluation results throughout the process in a storage device for subsequent analysis and user feedback.
