Description

Technical Field

[0001] This utility model relates to the field of fire protection, and in particular to a waterproof audible and visual alarm device. Background Technology

[0002] In the field of fire safety, audible and visual alarms are a key warning device. By emitting high-decibel sirens and strong flashing signals simultaneously, they can quickly attract people's attention in emergency scenarios such as fires and gas leaks, buying valuable time for evacuation and emergency response. Therefore, they are widely used in various indoor and outdoor scenarios such as residential buildings, large warehouses, industrial production plants, underground parking lots, and various ships.

[0003] While most mainstream audible and visual alarms on the market currently meet basic alarm and warning function requirements, and their siren sound pressure level and flash intensity typically meet industry standards, they suffer from significant design flaws in waterproof performance. This severely impacts the lifespan of the equipment and the reliability of emergency response. The specific problems are mainly reflected in the following two aspects:

[0004] On the one hand, poor sealing performance is caused by unreasonable sealing structure design. Traditional sound and light alarms often use simple rubber ring seals or seals that directly fill gaps with glue. Such sealing structures do not fully consider the impact of complex outdoor environments. When the alarm is exposed to outdoor conditions such as sun and rain for a long time, high temperature and ultraviolet rays will accelerate the aging and hardening of the rubber ring, while low temperature environment will easily cause the rubber ring to become brittle and crack. Rainwater washing and humidity changes will cause the glue sealing layer to delaminate and crack. After the sealing structure fails, external moisture, dust and other impurities can easily enter the inside of the alarm, which will not only cause internal circuit short circuits and corrosion of metal parts, but may also damage the sound unit and light unit, causing the alarm to lose its warning function and creating serious safety hazards.

[0005] On the other hand, the lack of drainage structure in the outer casing leads to water accumulation and damage. In actual use, even if the sealing structure is temporarily effective, condensation may still occur inside the alarm due to temperature changes. At the same time, in extreme environments such as heavy rain or spraying, a small amount of water may still seep into the interior. However, the outer casing design of existing audible and visual alarms generally does not consider the problem of water drainage and lacks a dedicated drainage channel or structure. Water that seeps into the interior cannot be discharged automatically. Water accumulation will not only accelerate the corrosion and aging of circuit components, but may also directly cause short circuits in the circuit board, causing alarm malfunctions. In severe cases, it may even cause permanent damage to the equipment, making it unable to play a warning role in emergency situations and posing a great risk to fire safety. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, this utility model aims to solve the waterproof problem of sound and light alarms, and provide a sound and light alarm with reasonable structure, strong sealing, active drainage, convenient maintenance and high waterproof rating.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A waterproof audible and visual alarm includes a base shell, an electronic board installed inside the base shell, a buzzer and a flashlight installed on the electronic board, and a top cover sealed by a first sealing ring on the base shell. A hollow connecting ring is provided on the top cover corresponding to the buzzer. The inner wall of the connecting ring is sealed to the outer side of the buzzer by a second sealing ring. A guide ring is provided inside the connecting ring. The diameter of the guide ring gradually decreases from the buzzer towards the top cover. A plurality of circumferentially arranged guide holes are provided at the connection between the guide ring and the inner wall of the connecting ring.

[0009] The flow guide ring divides the connecting ring into an inner cavity and an outer cavity, the flow guide hole connects the inner cavity and the outer cavity, and the buzzer is located in the inner cavity.

[0010] One of the flow guide holes is located at the lowest point of the connecting ring.

[0011] The top cover is fitted with a decorative element for concealing the airflow ring.

[0012] The decorative element has several rows of grid holes.

[0013] The decorative element is semi-transparent.

[0014] The top cover is semi-transparent.

[0015] The beneficial effects of this utility model are as follows: A top cover sealed by a first sealing ring is installed on the bottom shell of this utility model. A hollow connecting ring is provided on the top cover corresponding to the buzzer. The inner wall of the connecting ring is sealed to the outer side of the buzzer by a second sealing ring. A guide ring is provided inside the connecting ring, and several circumferentially arranged guide holes are provided at the connection between the guide ring and the inner wall of the connecting ring. The waterproof structure of the two sealing rings effectively prevents water vapor from entering. With the help of the guide ring and guide holes, internal water can be automatically and quickly discharged. At the same time, the semi-transparent top cover, decorative parts, hollow structure of the connecting ring, and grid holes ensure the normal transmission of the high-decibel siren sound. Its structure is simple, highly waterproof, and can operate stably for a long time in humid outdoor environments. It combines sound and light warning effects with aesthetics, and has high practical value and market prospects. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0025] Reference Figure 1-5 A waterproof audible and visual alarm includes a base shell 1, an electronic board 2 installed inside the base shell 1, a buzzer 3 and a flashlight mounted on the electronic board 2, and an upper cover 5 sealed by a first sealing ring 4 on the base shell 1. A hollow connecting ring 6 is provided on the upper cover 5 corresponding to the buzzer 3, and the inner wall of the connecting ring 6 is sealed to the outer side of the buzzer 3 by a second sealing ring 7. This two-stage waterproof sealing structure forms an all-around waterproof barrier from the assembly of the outer shell to the connection of the core components, effectively solving the problem of moisture intrusion caused by sealing failure in existing equipment. On the one hand, in the base shell 1... The first sealing ring 4 is provided at the assembly gap between the shell 1 and the upper cover 5, which can tightly fill the gap between the two and prevent external rainwater and moisture from entering the interior from the shell splice, thus avoiding direct contact between the electronic board 2, buzzer 3, and core components such as the flash and moisture. On the other hand, the second sealing ring 7 is provided at the assembly gap between the connecting ring 6 of the upper cover 5 and the outer side of the buzzer 3, which can specifically seal the critical gap at the installation position of the buzzer 3, preventing moisture from seeping into the inner cavity along the gap between the buzzer 3 and the connecting ring 6. The dual sealing structures work together to form a three-dimensional waterproof system of "overall shell sealing + local reinforced sealing of core components". Compared with traditional single rubber ring or glue sealing, the waterproof reliability is greatly improved. Even when exposed to outdoor sun, rain, spray and other humid environments for a long time, it can effectively resist moisture intrusion, significantly reduce the risk of internal circuit short circuits and component corrosion damage, and extend the service life of the equipment.

[0026] A guide ring 8 is provided inside the connecting ring 6. Several circumferentially arranged guide holes 9 are provided at the connection point between the guide ring 8 and the inner wall of the connecting ring 6. The guide ring 8 divides the connecting ring 6 into an inner cavity and an outer cavity, and the guide holes 9 connect the inner cavity and the outer cavity. The buzzer 3 is located in the inner cavity. To fully consider the normal functioning of the sound and light warning function and to avoid the waterproof design affecting the propagation of the siren sound, the double sealing ring only seals the gaps and does not obstruct the sound-emitting channel of the buzzer. The diameter of the flow ring 8 gradually decreases from the buzzer 3 towards the upper cover 5, forming a reverse horn-shaped structure, creating a smooth sound propagation path and ensuring that the high-decibel siren sound emitted by the buzzer 3 can penetrate smoothly. On the other hand, the smaller the diameter of the flow ring 8, the lower the probability of water ingress. In terms of drainage design, if water droplets splash into the inner cavity during use, i.e., drip into the buzzer 3, they will be automatically discharged through the flow hole 9, which can effectively prevent water accumulation and thus avoid damage to the alarm.

[0027] Furthermore, one of the drainage holes 9 is located at the lowest point of the connecting ring 6, which ensures that all accumulated water is drained.

[0028] The upper cover 5 is equipped with a decorative element 10 for shielding the flow guide ring 8. The decorative element 10 is provided with a plurality of arranged grid holes 11. The decorative element 10 is semi-transparent, and the upper cover 5 is semi-transparent, so that the strong flash emitted by the flash lamp can be clearly seen through without affecting the flash warning effect.

[0029] Its simple structure and strong waterproof performance enable it to operate stably in humid outdoor environments for extended periods. It achieves a perfect balance between "high waterproof performance" and "efficient sound and light warning," ensuring that in emergency situations, the equipment can emit a high-decibel siren and a strong flashing light to quickly attract people's attention and provide reliable protection for evacuation and emergency response. It has high practical value and market prospects.

[0030] Furthermore, a speaker can also be installed on the electronic board 2 to expand the alarm range of the buzzer 3.
