Description

Technical Field

[0002] Insomnia is a common sleep disorder that people often experience during normal sleep. Except for a very small number of pathological insomnia symptoms, most people's insomnia is caused by factors such as depression, anxiety, irritability, anger, and emotional out-of-control. Many scientific and technological workers who study insomnia symptoms have introduced many methods to relieve people's insomnia troubles. For example: playing music in a relatively quiet environment before going to bed, closing the curtains to create a quiet, safe and relaxing resting environment, etc.

Summary of the Invention

[0006] The embodiments of this specification provide the following technical solutions: An adaptive fragrance-releasing intelligent sleep aid pillow, comprising:

[0007] A pressure sensing mechanism, the pressure sensing mechanism comprising a flexible pressure sensor strip formed by a pressure sensor array integrated on a flexible PCB substrate, the flexible pressure sensor strip being embedded in the pillow interlayer and arranged centrally along the long side of the pillow;

[0008] A signal transceiver, the signal transceiver is connected to the pressure sensor through an FPC cable, the pillow core is reserved with a hole for the FPC cable to pass through, and the signal transceiver has a built-in main control chip and a battery;

[0009] The fragrance releasing mechanism is connected to the signal transceiver through a wire to control the fragrance releasing mechanism to release the fragrance sleep-inducing substance.

[0013] Preferably, the fragrance releasing mechanism comprises a B-type fragrance releasing capsule, which is a multi-layer fragrance cloth roll. The B-type fragrance releasing capsule is at least partially embedded in the groove and fixed by buckles at the upper and lower ends of the groove.

[0014] Preferably, the B-type fragrance-releasing sac comprises a B-type protective shell, a fragrance cloth roll, a temperature sensor and a heating rod, and the fragrance cloth roll is pressed against the B-type protective shell due to its tendency to expand outwards.

[0015] Preferably, the fragrance releasing mechanism comprises a fragrance releasing rope, and silicone buckles are installed at both ends and in the middle of the fragrance releasing rope, which are snapped into nylon buckles pre-buried in the left, right and upper edges of the pillow to form a three-point fixing layout.

[0016] Preferably, the fragrance-releasing rope is a rope body with a diameter of 4 mm, which is formed by a heating wire spirally wrapped around the fragrance yarn.

[0019] Compared with the prior art, the beneficial effects that can be achieved by at least one of the above technical solutions adopted in the embodiments of this specification at least include:

[0020] The fragrance release intensity can be intelligently adjusted in real time according to different sleep states. Without wearing a device, it can intelligently identify the sleep state and accurately control the fragrance release intensity. The flexible PCB substrate integrates a piezoresistive sensor array. By detecting the pressure distribution on the pillow surface, it can capture the head weight distribution, turning movements and breathing rhythm in real time. The signal transceiver receives the sensor data through an FPC cable, analyzes the pressure fluctuation frequency in combination with a temporal neural network, extracts the breathing rate and body movement frequency to classify and control the fragrance release intensity. When high-frequency body movements are detected during the sleep induction stage, it triggers a high-intensity fragrance release. After the pressure distribution stabilizes during the deep sleep maintenance stage, it switches to a constant-current fragrance release. The PID algorithm is used to maintain the fluctuation of the fragrance concentration. A personalized sleep profile is established through a transfer learning algorithm, and the characteristics such as the user's turning habits and breathing patterns are learned within a certain period of time, with a relatively high prediction accuracy. The system realizes the adaptive fragrance release with the accurate matching of the fragrance release intensity and the sleep stage through the multi-dimensional correlation analysis of pressure-physiological signals and the closed-loop feedback control algorithm. The fragrance release mechanism can be used for a long time and is relatively convenient to replace. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] like Figures 1-6As shown, in some embodiments, the surface of the pressure sensor strip 5 is covered with a medical-grade silicone protective layer, and the pressure sensor strip 5 is sewn into the interlayer reserved in the pillow core.

[0049] like Figures 1-6 As shown, in some embodiments, the signal transceiver 2 includes a main control board, a battery 3 and an aluminum alloy shell. The main control board and the battery 3 are installed in the aluminum alloy shell, and the aluminum alloy shell is fixed to the top central compartment of the pillow core 1 with screws.

[0050] See also Figures 1-6 , the specific manufacturing method will be described below:

[0051] 1. Pressure Sensing System Assembly

[0052] 1. Sensor array installation

[0053] The flexible pressure sensor strip is embedded in the interlayer of the pillow, arranged in the center along the long side of the pillow, and sewn into the interlayer reserved in the pillow core.

[0054] 2. Signal transmission connection

[0055] The cable of the sensor array passes through the reserved hole in the pillow core and is plugged into the interface of the signal transceiver. The interface is sealed with epoxy resin to prevent pulling.

[0056] 2. Assembly of the fragrance release mechanism

[0057] 1. Installation of A / B type fragrance sachets

[0058] Positioning method: grooves are opened on the edges of both sides of the pillow core, and after the A / B type fragrance release sac is inserted, it is fixed by the buckles at the upper and lower ends of the groove.

[0059] Electrical connection: The heating sheet / heating rod of the fragrance sachet is connected to the output end of the signal transceiver through a silicone insulated wire, and the wire is routed along the stitching groove of the pillow core.

[0060] 2. Arrangement of Incense Rope

[0061] Fixed structure: Silicone buckles are installed at both ends and in the middle of the fragrance release rope, which are inserted into the nylon buckles pre-buried on the left, right and upper edges of the pillow to form a three-point fixed layout.

[0062] Power supply connection: The positive and negative poles of the heating wire in the rope are connected to the power supply bus inside the pillow through spring contacts.

[0063] 3. Core control system integration

[0064] Signal transceiver assembly: Install the main control board and the battery into the aluminum alloy housing, fix them with screws at the central compartment on the top of the pillow core, insert the battery into the central compartment on the top of the pillow core, and connect it to the main control board through a connector.

[0065] Please refer to Figure 7 , and the working principle and algorithm mechanism will be elaborated below:

[0066] 1) Sleep monitoring principle:

[0067] Sampling method: Pressure signal acquisition

[0068] Turning over determination: The change gradient of adjacent sensor pressure values is higher than the set value

[0069] Insomnia judgment algorithm:

[0070] Initial 30-minute learning period → Analyze every 5-minute cycle

[0071] Abnormal condition: The number of turnovers in two consecutive cycles > 2 times / cycle.

[0072] 2) Temperature control and fragrance release mechanism:

[0073] PID temperature control: ±0.5°C accuracy

[0074] Gradient heating strategy:

[0075] The first cycle: 40°C

[0076] For each consecutive cycle increase of one gear, the temperature increases by 4°C (maximum 52°C)

[0077] Stop condition: The number of turnovers in two consecutive cycles ≤ 1 time / cycle.

[0078] 3) Theoretical basis for cycle judgment

[0079] 1. Initial 30-minute learning period

[0080] Physiological basis for sleep initiation: The human body usually needs a 15 - 30-minute transition period to fall asleep, and this period is used to establish a user's personalized baseline pressure model.

[0081] Dynamic baseline calibration: Eliminate misjudgments caused by initial lying position adjustment (such as pillow position adaptation, body relaxation process).

[0082] 2. 5-minute cycle division

[0083] Sleep microcycle theory: The sleep stage transition cycle is about 5 - 15 minutes (such as the subdivision of the NREM stage), and short cycles can capture stage characteristics.

[0084] Data processing balance: Balance real-time response (avoiding excessive delay) and noise filtering requirements.

[0085] 2.3 Continuous cycle determination logic

[0086] Assume that the current sleep state is related to the previous cycle. The continuous abnormal conditions improve the judgment confidence and reduce the misjudgment rate of accidental actions.

[0087] 4) Technical mechanism of the relationship between temperature increase gradient and sleep aid

[0088] Dose - effect curve:

[0089] 40°C (initial): Low concentration induces relaxation

[0090] 44 - 48°C (mid - term): Medium - high concentration maintains sleep continuity

[0091] 52°C (highest): Short - term high concentration is used for breakthrough intervention

[0092] Olfactory fatigue compensation: Gradual temperature increase offsets the olfactory adaptation effect and maintains the effectiveness of nerve stimulation.

[0093] Sleep depth feedback: In the deep sleep period (turning over ≤ 1 time / cycle), the temperature level is reduced to reduce excessive stimulation; in the light sleep period, the level is increased to strengthen the intervention.

[0094] 5) Technical explanation of the incense - stopping judgment conditions

[0095] Physiological state determination

[0096] Sleep stability index: Turning over ≤ 1 time in two consecutive cycles indicates entering the stable sleep stage, and at this time the demand for external stimulation decreases.

[0097] Risk avoidance of over - intervention: Continuous high - concentration aroma in the deep sleep period may reversely activate the arousal system.

[0098] System energy efficiency optimization

[0099] Energy consumption control: Stopping heating can reduce power consumption.

[0100] Extension of material life: The volatilization rate of aromatic substances decreases when the incense stops.

[0101] The following will conduct a quantitative analysis of the technical effects:

[0102] Monitoring system performance

[0103] Pressure detection accuracy: ±5N

[0104] Accuracy of turning - over recognition: 70%

[0105] Advantages:

[0106] Real-time performance: The sampling frequency of the pressure signal can reach the millisecond level (±5N accuracy), while at least 10 seconds or more of data is required for heart rate monitoring to extract effective rhythm features. Simplified signal processing: The pressure sensor array only needs to analyze the mechanical change gradient, while heart rate monitoring needs to process bioelectric / photoelectric plethysmogram signals, and has higher requirements for anti-motion artifacts.

[0107] Advantages of the fragrance release system

[0108] Temperature control:

[0109] Heating rate: 1℃ / 5s

[0110] Temperature uniformity: ±1℃

[0111] Lifetime indicators: The lifetime of the heating element > 5000 hours, and the lifetime of the fragrance release material > 2 weeks.

[0112] Benefits of structural innovation

[0113] Replaceable fragrance material: The replacement time < 20 seconds

[0114] Improved thermal efficiency: The heat transfer efficiency of Type A is 80%

[0115] Safety performance: Dual overheat protection (NTC + software protection), response time < 0.3s.
