Abstract
Description
Technical Field
[0001] The utility model relates to monitoring individual physiological indicators, and in particular to an early warning system for emotion recognition. Background Art
[0002] With the rapid development of industrialization and urbanization, people face increasing pressure in their work and personal lives. This pressure often stems from a fast-paced lifestyle, workplace competition, economic pressures, and interpersonal relationships. Emotional instability not only affects individual mental health but can also negatively impact decision-making for bus drivers, airline pilots, ship pilots, and stock / financial derivatives traders, leading to property damage, public safety, and social stability. Therefore, it is necessary to develop a detection device that not only helps individuals manage their emotions and reduce decision-making errors caused by mood swings, but also, on a broader societal level, promotes social harmony and stability by reducing the public harm and property damage caused by emotional instability.

[0036] The connecting portion 4 includes a connecting block 401 fixedly connected to the side of the housing 1 away from the wristband 3. A socket 402 for inserting the wristband 3 is provided on one side of the connecting block 401. A pressing block 403 is slidably connected to the inner wall of the socket 402.

[0038] Specifically, by pressing the limit bar 405 downward, the fixing rod 406 is driven to move downward until the locking block 407 corresponds to the locking groove, and the spring 408 resets and pushes the locking block 407 into the locking groove to lock the fixing rod 406. At the same time, the limit bar 405 drives the connecting rod 404 to move downward, and the connecting rod 404 drives the pressing block 403 to squeeze the wristband 3 inserted into the socket 402 to fix it so that the smart bracelet can be worn. At the same time, the pressing of the wristband 3 by the pressing block 403 can cut off the airway 9, so that the airflow only circulates in the wristband 3 around the wrist, thereby increasing the air flow at the wrist position and improving the drying effect.
[0039] The socket 402 passes through the inner wall of the accommodating cavity 5 so that the wristband 3 can extend into the accommodating cavity 5. The inner wall of the accommodating cavity 5 is fixedly connected with a guide plate 11, and a curved portion 12 is formed at one end of the guide plate 11 close to the connecting block 401.
[0040] Specifically, by inserting the wristband 3 into the accommodating cavity 5 along the socket 402 , the exposed length of the wristband 3 can be adjusted according to the size of the user's wrist, and by providing the guide plate 11 , the wristband 3 is located at the bottom of the accommodating cavity 5 .
[0041] The air supply component 6 includes an air bag 601 fixedly connected to the inner top wall of the accommodating chamber 5, an air inlet is provided on the surface of the air bag 601, and an air inlet check valve 602 is fixedly connected to the inner wall of the air inlet, a connecting hole 603 is provided on the surface of the outer shell 1, and an air outlet pipe 604 is rotatably connected to the surface of the air bag 601, one end of the wristband 3 is fixedly connected to a connecting pipe 605 connected to the air duct 9, the connecting pipe 605 is rotatably connected to one end of the air outlet pipe 604, and the surface of the connecting pipe 605 is fixedly connected to the air outlet check valve 606.
[0042] The lower surface of the airbag 601 is fixedly connected to a movable plate 607, which is slidably connected to the inner wall of the accommodating chamber 5. A fold 608 is provided on the surface of the airbag 601, and an electromagnet 609 is fixedly connected to the inner top wall of the accommodating chamber 5. The electromagnet 609 can adsorb the movable plate 607 when energized.
[0043] A microcontroller 610 and a battery 611 are respectively provided on the upper surface of the guide plate 11, the inner wall of the accommodating cavity 5 is fixedly connected to a base plate 612, the bottom of the base plate 612 is fixedly connected to a piezoelectric generator 613 that can be contacted by the wrist, the inner top wall of the accommodating cavity 5 is fixedly connected to a position sensor 614, a mounting port is opened at the bottom of the base plate 612, and a humidity sensor 615 is fixedly connected to the inner wall of the mounting port.
[0044] Specifically, by setting up a piezoelectric generator 613, during normal hand movements, the movement of the wrist will generate pressure on the piezoelectric generator 613, causing it to generate voltage and store it in the battery 611. By setting up a humidity sensor 615 and a position sensor 614 to cooperate with each other to control the on and off of the electromagnet 609, the airbag 601 can be exhausted and inflated, and the air in the airbag 601 can be sent out and air flow can be generated at the wrist, so that the smart bracelet has an energy-saving effect. Among them, the humidity sensor 615 is used to sense the humidity of the wrist, and the position sensor 614 is used to detect the position of the movable plate 607. When the humidity is low, the position sensor 614 is used to detect the position of the movable plate 607. When the sensor 615 and the position sensor 614 simultaneously meet the power-on conditions for the electromagnet 609, the battery 611 energizes the electromagnet 609. At this time, the electromagnet 609 adsorbs the movable plate 607, causing it to compress the airbag 601 and discharge the air in the airbag 601. When the humidity sensor 615 meets the power-on conditions and the position sensor 614 meets the power-off conditions, the electromagnet 609 is powered off. At this time, the movable plate 607 moves downward under its own gravity, the airbag 601 is reset and air is replenished. When the humidity sensor 615 and the position sensor 614 simultaneously meet the power-off conditions, the electromagnet 609 is powered off and no longer energized.
[0045] The bottom of the base plate 612 is fixedly connected to a skin galvanic response sensor 13 and a photoplethysmography sensor 14 that fit the wrist, and the upper surface of the housing 1 is fixedly connected to a microphone 15.
[0046] Specifically, the wearer's emotions and sleep quality are monitored by setting a skin galvanic response sensor 13, the user's heart rate and blood oxygen saturation are monitored by setting a photoplethysmography sensor 14, and the microphone 15 is used for calls.
[0047] Working principle: When the smart bracelet is used, the user first wears the smart bracelet on the wrist, inserts one end of the wristband 3 into the receiving groove from the socket 402 and extends it inward at the bottom of the receiving cavity 5 under the cooperation of the curved portion 12 and the guide plate 11 until the wristband 3 is appropriately tight. Then, the user presses down the limit bar 405, which drives the fixing rod 406 to move downward, and the fixing rod 406 drives the locking block 407 to move downward until the locking block 407 corresponds to the locking groove. The spring 408 resets and pushes the locking block 407 into the locking groove to lock the fixing rod 406. At the same time, the limit bar 405 drives the connecting rod 407 to move downward. 4 moves downward, the connecting rod 404 drives the pressing block 403 to squeeze the wristband 3 inserted into the socket 402 and fix it so that the user can wear the smart bracelet. At this time, the pressing block 403 can cut off the airway 9 by pressing the wristband 3, so that the air flow only circulates in the wristband 3 around the wrist, thereby increasing the air flow at the wrist position. During normal hand movements, the movement of the wrist will generate pressure on the piezoelectric generator 613, causing it to generate voltage and store it in the battery 611. The humidity sensor 615 senses the humidity of the wrist, and the position sensor 614 detects the position of the movable plate 607. When the humidity sensor 61 5 and the position sensor 614 simultaneously meet the power-on condition for the electromagnet 609, the battery 611 powers the electromagnet 609. At this time, the electromagnet 609 attracts the movable plate 607, causing it to compress the airbag 601 and discharge the air in the airbag 601. The discharged air passes through the air outlet pipe 604, the connecting pipe 605, and the air channel 9 in sequence, and is ejected from the air hole 10 into the flow groove 7. Then, it is discharged outward from the gap between the protrusion 8 and the wrist, thereby increasing the air circulation speed at the wrist position, accelerating the evaporation of sweat, and improving comfort. By utilizing the flow groove 7 and the protrusion 8, and setting the air hole 10 on the inner wall of the flow groove 7, the wrist is prevented from being damaged. Sweat enters the pores 10, and the circulation slots 7 are used to increase the space between the wristband 3 and the wrist for better air circulation, further increasing the rate of sweat evaporation. When the humidity sensor 615 meets the power-on condition and the position sensor 614 meets the power-off condition, the electromagnet 609 is powered off. At this time, the movable plate 607 moves downward under its own gravity, and the airbag 601 is reset and air is replenished. When the humidity sensor 615 and the position sensor 614 meet the power-off condition at the same time, the electromagnet 609 is powered off and no longer energized, thereby enabling the smart bracelet to solve the problem that the wristband 3 in the prior art is difficult to clean and easy to breed bacteria.
