This non-provisional patent application claims priority under 35 U. S. C. ยง 119 from Chinese Patent Application No. 2023226981003 filed on Oct. 9, 2023, the entire content of which is incorporated herein by reference.
The disclosure relates to the field of distress alarm technology, and in particular to a waterproof distress alarm device.
A buzzer is an integrated electronic sounder that is usually used as an alarm device. In the event of disasters or accidents in rivers or sea areas, it is mostly equipped with a lifeguard whistle, which requires the wearer to blow in order to make a sound. However, the efficiency of the lifeguard whistle is low, and using a buzzer for alarm is better choice.
However, most typical buzzers do not have waterproof functions, and when the typical buzzers come into contact with water, the typical buzzers will lose their function or have little effect that in the rescue process, rescue workers are unable to quickly and accurately locate the victims and causing rescue failures. Moreover, most of the typical buzzer alarms are prone to flooding and sinking into the river with the drowning person, resulting in poor performance of the flashing lights installed at a top of the buzzer alarm, which cannot provide assistance for search and rescue work. Therefore, a waterproof distress alarm is proposed.
The present disclosure provides a waterproof distress alarm, which has the advantages of being waterproof and being able to quickly activate the alarm and float on the water surface to provide assistance for subsequent search and rescue work in the event of an emergency for the user. It solves the problem of being waterproof in related technologies and unable to provide assistance for subsequent search and rescue work.
The present disclosure provides a waterproof distress alarm device, includes a housing; a base, detachably mounted to a bottom side of the housing, the base defining a through hole in a outer surface, and two limited recesses in two opposite inner sidewalls; a main board, mounted inside the housing and located at a bottom portion of the housing, the main board disposed two opposite limiting blocks at a outer surface of the bottom side of the main board; a battery holder, mounted inside the housing and located at a middle of the housing; a buzzer, mounted to a top side of the battery holder via wires; a buzzer chamber, mounted to a top side of the buzzer via wires; an LED light board, mounted to a top side of the buzzer chamber via wires, a supporting frame, mounted to a top side of the housing; a waterproof membrane, mounted to the top side of the housing and above the supporting frame; a top cover, mounted to the top side of the housing and above the waterproof membrane; and a floating ring, surrounded on an outer surface of the housing and secured to the top side of the housing.
Further, the base is further disposed a magnetic plate and a waterproof rubber pad at a bottom inner side, shapes of the bottom inner side and the main board are matched each other.
Further, a bottom part of the main board is passed out of the bottom side of the housing, the top side of the mother side is disposed a hall sensor, a sealing ring is located between the bottom part of the main board and the bottom side of the housing, the bottom part of the main board is disposed a charge socket.
Further, an elastic element is located inside the limiting block, the limiting block is a telescopic structure, an upper and a lower sides of the limiting block are curved.
Further, shapes and positions of the limiting blocks are matched to that of the limiting recesses accordingly.
Further, The limiting block, the main board, the battery holder, the buzzer, the buzzer chamber, the LED light board, the supporting frame are arranged from bottom to top of the housing.
Further, the top cover defines a hole, and the top cover is larger than the waterproof membrane.
Further, the floating ring is mounted to a connection between the top cover and the housing.
Further, the material of the floating ring is made of foam, and a diameter of the outer surface of the floating ring is larger than that of the outer surface of the housing
The working principle and beneficial effects of the disclosure are:
The waterproof distress alarm is used by cooperating the base with housing. When the waterproof distress alarm is used, the material characteristics of the floating ring can make the overall device always float vertically on the water surface during use. At the same time, a limit block and limit recesses are used to avoid accidental operation of the entire device during use, which may cause misunderstandings. In combination with the main board, buzzer chamber, the LED light board, and the waterproof membrane, the waterproof distress alarm can be activated and float on the water surface to provide assistance for subsequent search and rescue work in the event of an emergency, that is it can promptly alert rescuers in the event of an accident, and achieve waterproofing.
The following will provide a clear and complete description of the technical solution in the embodiments of the present disclosure, in conjunction with the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments in this present disclosure, all other embodiments obtained by ordinary technical personnel in this field without creative labor involve the scope of protection of the present disclosure.
Refer to
Working principle: when in use, first, effectively install each part of the structure in the inner cavity and top of housing 1 in sequence. When in use, use waterproof membrane 12 to effectively seal the top of housing 1 to prevent water from seeping in. At the same time, use the permeability of waterproof membrane 12 and the holes on the outer surface of the top cover 13 allows the light generated by the LED light board 10 to shine out during operation. At the same time, the shapes and positions of the limit blocks 6 are matched with that of the limit recesses 4, when using it, the base 2 is installed at the bottom of the housing 1 and connected to the bottom of the motherboard 5, the stability of the base 2 installation is increased by using the limit blocks 6 and the limit recesses 4 to avoid easy loosening and separation from the bottom of the housing 1.
When in use, the user suspends the waterproof distress alarm assembled around their neck by threading the connecting rope through the through hole 3. In case of emergency, the user manually or passively stretches the base 2 to separate the base 2 from the bottom of the housing 1. Because the inner cavity of the base 2 is equipped with magnets and waterproof rubber pads, and the top of the motherboard 5 is fixedly installed with Hall sensors, when the base 2 separates from the outer surface of the bottom of the motherboard 5 at the bottom of the housing 1, at this time, the Hall sensor on the top of motherboard 5 detected a weakening magnetic field, triggering the alarm to work. The alarm signal is transmitted to the buzzer 8 through a wire, and LED light board 10 is activated, causing the overall device to emit an alarm and warning light. Combined with the material characteristics of floating ring 14, the overall device remained in a vertical state and floated on the water surface, making it easier for subsequent rescuers to detect.
