[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0043] like Figures 1 to 3 As shown, this utility model embodiment provides an alarm device, which includes a light-emitting module 01. The light-emitting module 01 has a housing 10, a control board 20, a strobe light 30, and an indicator light group 40. The housing 10 has a receiving cavity, and the control board 20 is disposed in the receiving cavity. The control board 20 has a receiving module, an alarm module, and an information processing module. The alarm module is electrically connected to the strobe light 30 and can emit an alarm signal through the strobe light 30. The receiving module is used to receive different types of alarm signals. The information processing module has multiple prompting modes and is electrically connected to the indicator light group 40. The information processing module controls the indicator light group 40 to work according to different prompting modes.
[0044] This invention provides an alarm device, wherein the light-emitting module 01 of the alarm device consists of a housing 10, a control board 20, a strobe light 30, and an indicator light group 40. The alarm module on the control board 20 is electrically connected to the strobe light 30, and the information processing module is electrically connected to the indicator light group 40. When the receiving module receives an alarm signal of a certain type, the alarm module immediately controls the strobe light 30 to flash to issue an alarm. At the same time, the information processing module immediately generates a corresponding prompt mode for the received alarm signal, so as to flexibly control the indicator light group 40 to alert personnel. Based on the principle of the above-mentioned modules working together, when the alarm device detects an alarm signal, it can quickly attract the user's attention through the strobe light 30 and provide the user with intuitive alarm information through the indicator light group 40, ensuring that even hearing-impaired users can quickly detect the alarm in emergency situations such as fires and gas leaks, and thus take appropriate avoidance measures.
[0045] Furthermore, the alarm device also includes a vibration module 50, which is electrically connected to the alarm module. The alarm module can control the vibration module 50 to provide vibration alerts. In this embodiment, the vibration module 50 is used to enhance the alarm module's alerting effect on the user, ensuring that even when no sound or visual signal can be heard, the user can still perceive an emergency through the vibration of the vibration module 50.
[0046] Specifically, the vibration module 50 is electrically connected to the alarm module via a connecting cable 54, which is at least 3 meters long, to ensure that the user can always receive vibration alerts while moving around in the room. In other embodiments, the vibration module 50 may also be wirelessly connected to the alarm module.
[0047] Specifically, the light-emitting module 01 can be fixed on a table or wall, and the vibration module 50 can be in the form of a vibration pad. The vibration pad can be carried with you or placed under your pillow or mattress so that you can feel the vibration while sleeping, wake up the user in time and remind him of an emergency.
[0048] Furthermore, the housing 10 has a front side 11 and a back side 12 arranged opposite to each other. The front side 11 has a first light-transmitting part and a second light-transmitting part. The first light-transmitting part is arranged corresponding to the strobe light 30, and the second light-transmitting part is arranged corresponding to the indicator light group 40. In this embodiment, by aligning the first light-transmitting part with the strobe light 30 and the second light-transmitting part with the indicator light group 40, it is ensured that light can be emitted smoothly without being blocked or interfered with by other components. Moreover, by placing the first light-transmitting part and the second light-transmitting part on the housing 10, it can effectively support and protect the internal strobe light 30 and indicator light group 40, and also achieve efficient and intuitive visual alarm, improving the user's alertness and safety response efficiency.
[0049] like Figure 1 and Figure 3 As shown, the back panel 12 has multiple connection ports 121, which are electrically connected to the alarm module. The vibration module 50 can be electrically connected to any one of the connection ports 121. In this embodiment, the design of the connection ports 121 allows the vibration module 50 to be easily added or removed without requiring complex hardware modifications to the alarm system. Furthermore, multiple connection ports 121 can be connected to multiple vibration modules 50, allowing users to connect an appropriate number of vibration modules 50 according to their personal or family needs.
[0050] Specifically, the multiple connection ports 121 provide flexible expandability and compatibility, allowing the vibration module 50 to be used not only as a single vibration pad, but also to be connected to other vibration devices with ports via the connection cable 54, in order to meet the needs and lifestyles of different users.
[0051] Furthermore, the second light-transmitting part has a mounting hole 111. The indicator light group 40 includes a light guide part 41 and multiple indicator lights 42. The multiple indicator lights 42 are of different colors and are spaced apart on the control panel 20. One end of the light guide part 41 is located outside the housing 10, and the other end of the light guide part 41 passes through the mounting hole 111 into the housing 10 and is set corresponding to the multiple indicator lights 42.
[0052] In this embodiment, the indicator light group 40 consists of a light guide 41 and multiple indicator lights 42 of different colors. These indicator lights 42 are spaced apart on the control panel 20, forming a clear visual identifier. Different colored indicator lights 42 can provide users with different information, making it easy for users to quickly identify them. One end of the light guide 41 passes through the mounting hole 111 on the second light-transmitting part into the housing 10, precisely aligned with the multiple indicator lights 42 on the control panel 20. The other end is located on the outside of the housing 10, directly exposed to the user's line of sight. Through the above structure, the light from the indicator lights 42 can be efficiently transmitted to the outside of the housing 10 through the light guide 41, enhancing the brightness and visibility of the light. Especially at night or in smoky environments, the use of the light guide 41 significantly enhances the penetrating power of the light, making the warning effect more significant, and ensuring that information can be effectively conveyed under any lighting conditions.
[0053] Specifically, indicator lights 42 of different colors can indicate power connection status, fire alarm, gas alarm, device malfunction, and whole-house interconnection status. In another embodiment, indicator lights 42 of the same color can indicate different danger information by the number of lights on or the frequency of their illumination.
[0054] Furthermore, the first light-transmitting part includes a light-transmitting cover 112, with a light-transmitting hole 113 on the front side 11. The light-transmitting cover 112 is placed over the light-transmitting hole 113. The strobe lamp 30 is located inside the housing 10 and is positioned corresponding to the light-transmitting hole 113. The strobe lamp 30 transmits light signals through the light-transmitting cover 112. In this embodiment, a light-transmitting hole 113 is designed on the front side 11 of the housing 10, and the position of the light-transmitting hole 113 directly corresponds to the internal strobe lamp 30, ensuring that light can be emitted directly and accurately from inside the housing 10. Placing the light-transmitting cover 112 over the light-transmitting hole 113 can optimize the propagation effect of the light signal emitted by the strobe lamp 30, amplify the illumination area of the strobe lamp 30, and ensure that it can quickly attract the attention of surrounding people in emergency situations such as fires and gas leaks.
[0055] Specifically, the light-transmitting cover 112 is usually made of a high light transmittance material, and its interior may be designed with a reflective coating or a microprism structure. These designs can effectively focus and guide the light emitted by the strobe lamp 30, improve the utilization rate of light, and ensure that the light signal can be clearly seen even at a distance or in a dimly lit environment.
[0056] Specifically, the flashing frequency and intensity of the strobe lamp 30 can be automatically adjusted according to the intensity of the external ambient light to ensure the best light propagation effect under various environmental conditions.
[0057] Furthermore, the alarm device also includes a gateway and a detection component. The gateway is electrically connected to the detection component and the receiving module, respectively. The detection component includes at least one of a temperature detector, a smoke detector, a gas detector, a water leak detector, and a power failure detector.
[0058] In this embodiment, the gateway is electrically connected to both the detection component and the receiving module, responsible for collecting and transmitting detection data, and coordinating with other alarms in the space to trigger alarm responses. The detection component includes various environmental monitoring sensors that can comprehensively monitor security risks in the home environment and immediately send a signal to the gateway upon detecting any anomalies.
[0059] Specifically, other alarms in the home can be connected through a gateway. When any alarm is triggered, the light-emitting module 01 and the vibration module 50 connected to the light-emitting module 01 will also trigger an alarm.
[0060] Furthermore, the light guide 41 has a ring-shaped structure, and the alarm device also includes a button 60. The button 60 is located on the front 11 and is electrically connected to the control board 20. The light guide 41 is arranged in a ring around the outer periphery of the button 60. In this embodiment, the light guide 41 adopts a ring-shaped structure and is arranged around the button 60 to form a complete light band, ensuring that the light is evenly distributed around the button 60 and improving the user's perception of the alarm signal. The button 60 is located on the front 11 of the housing 10, in the center of the light guide 41, which maximizes the use of the space on the front 11 of the housing 10 and facilitates user operation.
[0061] Specifically, the functions of button 60 include, but are not limited to, alarm testing and mode switching. In this embodiment, button 60 is used to detect whether the alarm device is kept in a normal power-on state.
[0062] Specifically, the button 60 and the control board 20 are electrically connected through a conductive pad or a metal spring to ensure that when the user presses the button 60, the signal can be accurately transmitted to the control board 20.
[0063] like Figure 3 As shown, the alarm device also includes a battery module 70 and a power interface 80, which are electrically connected to the control board 20. In this embodiment, the alarm device automatically charges via the power interface 80 and remains connected to an external power source at all times. In the event of an external power outage or instability, the battery module 70 provides continuous power support, preventing the alarm device from becoming unusable due to power failure.
[0064] Specifically, the battery module 70 includes a battery 71 and a battery cover 72. The capacity of the battery 71 should be sufficient to support the alarm device to work continuously for a certain period of time in an emergency, such as 30 minutes to 2 hours, to ensure that an alarm signal is effectively issued.
[0065] Furthermore, the vibration module 50 includes a housing 51, a vibration motor 52, and a circuit board 53. The vibration motor 52 and the circuit board 53 are located inside the housing 51, and the circuit board 53 is electrically connected to the alarm module and the vibration motor 52, respectively. In this embodiment, the circuit board 53 is electrically connected to the alarm module. Once an alarm signal is received, the vibration motor 52 is immediately activated, thereby achieving instant linkage with the light-emitting module 01.
[0066] Specifically, the circuit board 53 includes a power supply device 531, which is connected to the alarm module via a connecting line 54 to ensure a stable power supply while maintaining communication with the alarm module. Once the receiving module detects an emergency such as a fire or gas leak, it immediately triggers the vibration motor 52 to start.
[0067] In this embodiment, the vibration module 50 itself does not have a power storage function. It must always be connected to the alarm module for use, thus avoiding the risk of the vibration module 50 failing to vibrate properly due to insufficient power. In other embodiments, the vibration module 50 may also be equipped with a power storage mechanism and a power display mechanism. The vibration module 50 achieves vibration alarm through wireless connection with the alarm module, while the power display mechanism can show the power level in real time. When the power is low, the user can charge it in time to ensure the normal use of the vibration module 50.
[0068] In practical applications, the receiving module continuously collects signals from the detection components. Once abnormal data is detected, the receiving module immediately sends the corresponding abnormal signal to the information processing module. The information processing module analyzes the signal type and intensity, activates the corresponding indicator light 42, and simultaneously sends a control command to the alarm module to activate the strobe light 30 and the vibration module 50. The strobe light 30 emits light in a high-speed flashing manner, generating a strong visual stimulus to ensure that the user immediately notices the alarm and understands the type of emergency. The vibration module 50 emits strong vibrations to enhance the alarm effect. If the alarm device is already connected to other alarm devices in the home through a gateway, the information processing module will forward the received emergency signal to these devices, triggering a whole-house alarm. This means that in addition to the current alarm device sounding the alarm, other connected devices will also activate their respective alarm mechanisms, such as smart door locks automatically unlocking, so that users can evacuate quickly and safely.
[0069] The alarm device of this application has the following beneficial effects:
[0070] 1. By employing a strobe light 30 and a vibration module 50 as the primary output methods for alarm signals, the perceptibility of the alarm can be significantly enhanced, especially for hearing-impaired users. The high-frequency flashing light generates a strong visual stimulus, and combined with the vibration effect of the vibration module 50, it ensures that users can promptly detect emergencies regardless of their situation. Furthermore, users can selectively use either the strobe light 30 or the vibration module 50 according to their actual needs, which not only improves resource utilization efficiency but also enhances the system's flexibility and scalability, facilitating future additions of functions or component updates.
[0071] 2. The information processing module in this application can control the indicator light group 40 to operate in multiple color modes, thereby conveying different types of security threat information. This multi-mode indicator function allows users to easily identify specific alarm types such as fire, gas leak, or power failure based on the light color and flashing pattern, improving the accuracy of alarms and the efficiency of response measures.
[0072] 3. By connecting with other smart devices in the home through communication technologies such as gateways, a home security network is formed. Once any device detects an emergency, the information will be shared in real time, triggering a home-wide alarm, which enhances the overall security of the home and ensures that all members can receive alarm information in a timely manner.
