[0043] The application scenarios of this application are mainly based on electronic alarm devices, and can also be applied to other scenarios according to their functions. The application scenarios are not restricted and limited by the specific embodiments described in this application.

[0044] Second, due to the high cost, complex processing and maintenance processes, and long production cycle in the design and manufacture of traditional electronic alarm devices, and there are problems with stability and reliability of the products, this application specifically provides technical solutions to solve the above problems. The technical solutions, working principles and technical effects of this application will be described in detail below in combination with specific embodiments.

[0045] Embodiment 1

[0046] This application provides an electronic alarm device, which is applicable to various scenarios, such as factories, schools, hospitals, public places, etc., and provides reliable safety protection for various environments.

[0047] As Figure 1 , Figure 2 shown, an electronic alarm device mainly includes a housing, a sound generator 3, an optical signal generator 4, a controller 10, and a power supply module 12.

[0048] The housing is made of PC (polycarbonate) material. The impact resistance and heat resistance of the PC material enable the alarm device to operate stably in a more severe environment and extend the service life of the product.

[0049] Among them, the housing includes a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are an integral structure, and this design enhances the overall strength and stability of the housing.

[0050] In order to facilitate the installation of electrical components and maintenance, first openings 21 are provided at both the end and the side of the second housing 2. The sealing end cover 6 is connected to the first opening 21 at the end by screws and sealed with sealant. This design enhances the overall strength and stability of the housing.

[0051] A side cover plate 7 is provided at the first opening 21 on the side of the second housing, which is used to seal the first opening 21 on the side, protect the internal electrical components from external environmental interference, and facilitate maintenance at the same time.

[0052] As an optimization, a plurality of strip-shaped or hole-shaped through holes arranged at intervals are provided at the end or circumferentially of the first housing 1. The design of the through holes enables the alarm sound emitted by the horn speaker to be smoothly transmitted to the external environment, improving the sound penetration and propagation distance, so as to ensure that people can be quickly noticed in case of emergency.

[0053] In this embodiment, the through holes are designed at the end of the first housing 1, which can ensure that the sound can be directly transmitted outward without being blocked inside the housing.

[0054] As an alternative, the through holes can also be provided circumferentially on the first housing 1. Compared with the through holes provided at the end, the design of the circumferential through holes can enable the sound to be evenly transmitted from multiple directions of the housing, reducing the directivity of sound propagation, making the sound coverage wider and more evenly distributed. In addition, the through holes are evenly distributed circumferentially on the housing, which helps to reduce the reflection and standing wave phenomena of sound inside the housing, thereby improving the clarity and sound quality of the sound.

[0055] As an enhanced solution, in addition to the through holes at the end, part of the design may also include providing through holes circumferentially (i.e., on the side) of the first housing 1 to increase the sound diffusion angle, so that the alarm signal can be perceived within a wider range.

[0056] Preferably, the through holes are designed as strip-shaped through holes, which have a longer length and a relatively narrow width, facilitating the directional propagation of sound and increasing the propagation distance and effect.

[0057] As an alternative, the through holes can also be hole-shaped through holes, which are small holes of circular or other shapes and are arranged in an array, enabling the sound to be evenly distributed and diffused, improving the coverage range and warning effect of the alarm signal.

[0058] In this example, the sound generator 3 uses a horn speaker. The sound generator 3 is connected to the control board of the controller 10 through a connection component and is installed in the second housing 2, which can efficiently focus and transmit the sound to a farther distance, making the alarm sound clearer and louder and can be recognized even in a noisy environment.

[0059] Among them, the connection component includes a connection plate 8 and a connection column 9. An installation groove 81 is opened on the connection plate 8 for fixing the horn speaker. One end of the connection column 9 is connected to the connection plate 8 through a connection block, and the other end is connected to the control board.

[0060] In this embodiment, the connecting plate 8 is a connecting plate 8 with a crossbeam structure, and the connecting column 9 is selected as a plastic rod.

[0061] The crossbeam structure usually has high rigidity and stability and can withstand large loads. Applying the crossbeam structure to the connecting plate 8 can effectively enhance the strength and stability of the connection and ensure the stability of the entire structure.

[0062] As Figure 2 、 Figure 3 shown, the optical signal generator 4 includes multiple groups of LED light sources 41. These LED light sources 41 are distributed in a circular array and are installed in a lamp cover 5 with a ring-shaped cylindrical structure inside the second housing 2. The LED light sources 41 use LED surface mount lamps.

[0063] By distributing multiple groups of LED light sources 41 in a circular array, uniform distribution and wide coverage of the optical signal are achieved, improving the visibility and recognition of the optical signal.

[0064] In this embodiment, LED surface mount lamps are used as the LED light sources, which have the advantages of small volume, high brightness, low energy consumption, long lifespan, etc., and are suitable for occasions that require long-term operation and have high requirements for the stability of the light source.

[0065] In addition, the design of the lamp cover 5 not only provides a stable installation environment for the LED light sources 41, but also performs a certain degree of preliminary shaping and focusing on the light through its shape and material.

[0066] A Fresnel lens 51 is provided on the lamp cover 5, and its deflection angle is 60° - 90°. It is used to focus and adjust the light emitted by the LED light sources 41, concentrating the light in a specific direction, thereby enhancing the visibility and penetration of the optical signal. Through the focusing effect of the Fresnel lens 51, the optical signal can be clearly recognized even at a relatively long distance or in an environment with poor light conditions, improving the practicality and reliability of the optical signal generator 4.

[0067] The controller 10 is used to control the sound generator 3 and the optical signal generator 4 to work in a synchronous or asynchronous manner.

[0068] To facilitate the installation of the LED light sources 41, a base 101 is provided on the controller 10. The base 101 is set as a cone or a cylinder. Installation positions are provided in the circumferential direction of the base 101 for installing the LED light sources 41. The installation angles of the installation positions can be the same or different. In this embodiment, the installation angles of the installation positions are the same, and multiple groups of LED light sources 41 are correspondingly installed on the installation positions of the base 101 along the circumferential direction of the base 101.

[0069] The controller 10 receives an alarm signal from the outside or inside, and controls the horn speaker to emit a preset alarm sound, and controls the LED light source 41 to emit a preset alarm light signal.

[0070] The power module 12 is installed in the housing to provide a stable working power supply for the sound generator 3 , the optical signal generator 4 and the controller 10 .

[0071] In addition, the power module 12 can also be replaced by a transformer module, which is connected to an external power source to provide working power for the alarm device.

[0072] In practical applications, when the electronic alarm device receives an alarm signal, the controller 10 will immediately control the horn speaker to emit a loud alarm sound, and at the same time control the LED light source 41 to emit a bright alarm light signal. Due to the focusing and adjustment of the Fresnel lens 51, the alarm light signal can still maintain clear visibility at a long distance or in a complex environment, thereby effectively improving the efficiency and reliability of the alarm.

[0073] Combined with the above-mentioned description of the mechanism design and technical effects, the specific working principle of the electronic alarm device is as follows:

[0074] When the electronic alarm device detects that a preset alarm condition is triggered, it receives an alarm signal, which is transmitted to the controller 10, and the controller 10 is then activated and starts to execute its preset alarm program.

[0075] First, the controller 10 sends a control signal to the sound generator 3 (horn speaker) to make it start to emit a preset alarm sound.

[0076] When the sound generator 3 emits an alarm sound, the controller 10 activates the optical signal generator 4 at the same time or later, and the LED light source 41 in the optical signal generator 4 begins to emit a preset alarm light signal, which is focused and adjusted by the Fresnel lens 51 on the lampshade 5 to form a brighter and more eye-catching light beam, further enhancing the alarm effect.

[0077] The sound generator 3 and the light signal generator 4 work simultaneously to form a sound and light synchronous alarm effect. The sound generator 3 and the light signal generator 4 cooperate with each other to improve the efficiency and reliability of the alarm.

[0078] The alarm will continue until the alarm condition is removed or the alarm device is manually turned off. Once the alarm condition is removed, the controller 10 will stop sending control signals, and the sound generator 3 and the light signal generator 4 will also stop working.

[0079] Embodiment 2

[0080] like Figure 4As shown, the difference between this application and the first embodiment lies in the design of the housing. The housing includes a first housing 1 and a second housing 2. A second opening 11 is provided on the side of the second housing 2, and a side cover plate 7 is provided at the second opening 11 to close the second opening 11 on the side of the second housing 2. The side cover plate 7 and the housing are fixed together by fasteners (such as screws) or other reliable connection methods.

[0081] Between the second opening 11 and the side cover plate 7, a layer of sealing ring is provided. The sealing ring is usually made of elastic material and has good sealing performance and aging resistance. When installing the side cover plate 7, the sealing ring will be compressed and closely fit on the opening edge, forming an effective sealing barrier.

[0082] In this embodiment, through the design of the sealing ring, it effectively prevents external dust, moisture and other impurities from entering the housing interior through the second opening 11, protects the internal components from damage, improves the reliability and service life of the alarm device, and further improves the overall protection level of the housing, enabling it to work under more adverse environmental conditions.

[0083] In this example, through the optimized design of the housing structure, the protection performance of the housing is improved. At the same time, the side cover plate 7 adopts a detachable design, ensuring the maintainability of the internal components. When maintenance and repair are required, simply opening the side cover plate 7 can easily access the internal components.

[0084] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.

[0085] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them; when the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
