Description

Technical Field

[0001] This utility model relates to the field of smart wearable technology, and in particular to a wearable heatstroke early warning and monitoring device. Background Technology

[0002] With the rapid development of smart wearable devices, various health bracelets are becoming increasingly popular. For outdoor workers, especially during the summer months when they face risks such as heatstroke and heat exhaustion, using health bracelets for health monitoring is essential. However, due to the significant increase in perspiration in hot weather, and the corrosive nature of sweat on the bracelet's sealing ring, existing bracelets require replacement of the sealing ring every 2-3 months to maintain good waterproofing in hot environments. Furthermore, users often cause a decrease in sealing performance when replacing the sealing ring themselves due to improper operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wearable heatstroke early warning and monitoring device that can overcome the shortcomings of the existing technology, facilitate the replacement of the sealing ring, and improve the sealing performance of the wristband.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A wearable heatstroke early warning and monitoring device includes an outer shell with a wristband attached to it. A heart rate sensor, a blood oxygen sensor, a body temperature sensor, and a sweat sensor are housed inside the outer shell. A sweat collection slot is provided on the wristband and communicates with the sweat sensor. The outer shell also houses a controller that communicates with the heart rate sensor, blood oxygen sensor, body temperature sensor, and sweat sensor, as well as an alarm that communicates with the controller. A display screen is located on the top of the outer shell, and a detachable bottom shell is located on the bottom edge. A first groove is provided on the bottom edge of the outer shell, with two parallel elastic baffles fixed in the middle of the groove, leaving a gap between them. A first sealing ring is installed between the outer elastic baffle and the outer edge of the first groove, and a second sealing ring is installed between the inner elastic baffle and the inner edge of the first groove. A ball head is provided on the inner side of the bottom shell, which is inserted into the gap between the two elastic baffles, with an interference fit between the ball head and the two elastic baffles.

[0006] Preferably, the inner side of the bottom shell is provided with two second grooves that respectively contact the first sealing ring and the second sealing ring, and the surface of the second groove is provided with a rubber layer.

[0007] Preferably, the first sealing ring is made of neoprene rubber with a hardness of 65 Shore A, and the second sealing ring is made of polyurethane with a hardness of 80 Shore A.

[0008] Preferably, an elastic metal ring is provided inside the second sealing ring.

[0009] Preferably, the housing also includes a Bluetooth module and a GPS module.

[0010] A monitoring method for the aforementioned wearable heatstroke early warning and monitoring device includes the following steps: a heart rate sensor, a blood oxygen sensor, a body temperature sensor, and a sweat sensor collect the wearer's corresponding physiological data in real time and send it to a controller. The controller displays the received data on a display screen. The controller sets a weighting coefficient for each type of data, multiplies the deviation of data exceeding a preset threshold from its corresponding threshold by the corresponding weighting coefficient, and then sums the results. If the summation result exceeds the preset threshold, an alarm is triggered.

[0011] The beneficial effects of adopting the above technical solution are as follows: the heatstroke warning device provided by this utility model is small in size, easy to wear, and does not affect normal outdoor work. It can monitor the physiological indicators of outdoor workers in real time and provide immediate warnings of potential heatstroke. This utility model improves the sealing structure for outdoor wear, enhances waterproof sealing, and allows users to easily replace the sealing ring themselves. Attached Figure Description

[0014] Reference Figs. 1-2 The wearable heatstroke early warning and monitoring device disclosed in this utility model includes an outer shell 1, a wristband 2 connected to the outer shell 2, a heart rate sensor 3, a blood oxygen sensor 4, a body temperature sensor 5, and a sweat sensor 6 installed inside the outer shell 1, a sweat collection groove 7 installed on the wristband 2, the sweat collection groove 7 being connected to the sweat sensor 6, a controller 8 communicating with the heart rate sensor 3, blood oxygen sensor 4, body temperature sensor 5, and sweat sensor 6, and an alarm 9 communicating with the controller 8 are also installed inside the outer shell 1, a display screen 10 is installed on the top of the outer shell 1, and a detachable bottom shell 11 is installed at the bottom of the outer shell 1.

[0015] Heart rate sensor 3, blood oxygen sensor 4, body temperature sensor 5, and sweat sensor 6 collect the wearer's corresponding physiological data in real time and send it to controller 8. Controller 8 displays the received data on display screen 10. Controller 8 sets a weighting coefficient for each type of data, multiplies the deviation of data exceeding the preset threshold from its corresponding threshold by the corresponding weighting coefficient, and then sums them. If the summation result exceeds the preset threshold, alarm 9 will sound an alarm.

[0016] The outer casing 1 also houses a Bluetooth module 21 and a GPS module 22. The controller 8 can connect to the user's mobile phone via the Bluetooth module 21, and simultaneously locate the user's position in real time via the GPS module 22, facilitating immediate rescue in case of an accident.

[0017] To address the problems of inconvenient installation of sealing rings and poor resistance to sweat corrosion in existing health bracelets, this invention improves the sealing structure of the outer shell 1. A first groove 12 is provided on the bottom edge of the outer shell 1. Two parallel elastic baffles 13 are fixed in the middle of the first groove 12, with a gap between the two elastic baffles 13. A first sealing ring 14 is installed between the outer elastic baffle 13 and the outer edge of the first groove 12, and a second sealing ring 15 is installed between the inner elastic baffle 13 and the inner edge of the first groove 12. A ball head 16 is provided on the inner surface of the bottom shell 11, which is inserted into the gap between the two elastic baffles 13, and the ball head 16 is press-fitted with the two elastic baffles 13. Two second grooves 18 are provided on the inner surface of the bottom shell 11, respectively contacting the first sealing ring 14 and the second sealing ring 15. A rubber layer 19 is provided on the surface of the second grooves 18. After the bottom shell 11 is engaged with the outer shell 1, the ball head 16 presses the two elastic baffles 13 to both sides, causing deformation. This, in turn, deforms the sidewalls of the two sealing rings, thereby generating more support force in both the upward and downward directions and improving the sealing effect. By designing the second groove 18, the force at the contact point between the sealing ring and the bottom shell 11 can be made more uniform. This pressure sealing design does not require special installation tools and can be achieved by hand, making it convenient for users to operate themselves.

[0018] A beveled portion 17 is provided at the edge where the bottom shell 11 and the outer shell 1 meet. The beveled portion 17 can optimize the radial force uniformity of the bottom shell 11 after the two sealing rings are tightly pressed with the sealing parts, making it easier for users to install the bottom shell 11.

[0019] The first sealing ring 14 is made of neoprene rubber with a hardness of 65 Shore A, and the second sealing ring 15 is made of polyurethane with a hardness of 80 Shore A. An elastic metal ring 20 is disposed inside the second sealing ring 15. The first sealing ring 14 is made of a softer material, while the second sealing ring 15 is made of a harder material. This is because the first sealing ring 14 comes into contact with more sweat on its outer surface, making it easier to replace when worn, while the second sealing ring 15 has a longer replacement cycle and is therefore more durable.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
