[0001] The utility model relates to the technical field of gas detection equipment, in particular to an integrated wireless sound and light alarm for a gas detector. Background Art

[0002] Gas leaks are a common safety hazard in modern buildings and industrial environments. To promptly detect and address these hazards, gas detectors are often installed to monitor gas concentrations in the environment. When gas concentrations exceed a preset safety threshold, traditional gas detectors trigger an alarm, alerting personnel to take appropriate safety measures. However, existing detection and alarm systems only provide audible or visual warnings, lacking intuitive visual guidance. This makes it difficult for evacuees to quickly locate the correct evacuation direction in an emergency. Utility Model Content

[0003] In order to solve the problems in the above background technology, the utility model provides an integrated wireless sound and light alarm for a gas detector.

[0004] The solution adopted by the utility model to solve its technical problems is: an integrated wireless sound and light alarm for gas detectors, characterized in that it includes a gas detector body, an sound and light alarm and a laser pointer for emitting laser indication light, the gas detector body includes a first shell, and a rotating mechanism for driving the sound and light alarm to rotate circumferentially around the gas detector body is further provided between the first shell and the sound and light alarm, the laser pointer is installed on the end of the sound and light alarm away from the first shell, and the rotating mechanism can drive the laser pointer to rotate to the correct orientation and point out the correct evacuation direction.

[0005] By adopting the above technical solution, an audible and visual alarm can be issued when the gas detector detects dangerous gas, and a laser indicator can also provide intuitive guidance on the correct evacuation direction.

[0006] Furthermore, the rotating mechanism includes a movable shell that is sleeved on the outer wall of the first shell and fixedly connected to the sound and light alarm, a driven gear provided at one end of the movable shell and inserted into the first shell, a driving gear engaged with the driven gear, and a driving motor for driving the driving gear to rotate.

[0008] Furthermore, the sound and light alarm includes a second shell, in which a control mainboard electrically connected to the laser indicator is provided, and the control mainboard includes a wireless communication module for sending alarm information to a monitoring terminal.

[0009] By adopting the above technical solution, the status of the alarm and the laser pointer can be controlled at any time through the terminal device.

[0010] Furthermore, the sound and light alarm device also includes a speaker for issuing an audible alarm and an alarm light for issuing a visual alarm, and the speaker and the alarm light are both electrically connected to the control mainboard.

[0011] By adopting the above technical solution, the sound and light alarm can quickly sound an alarm when the gas concentration exceeds the standard, thereby achieving the purpose of safety early warning.

[0012] Furthermore, a battery compartment is provided in the second shell, and a backup power supply for supplying power to the laser pointer is provided in the battery compartment.

[0013] By adopting the above technical solution, it is ensured that the laser pointer can still work normally when the main power supply fails or cannot be used.

[0014] In summary, the present invention provides the following beneficial effects: By integrating a gas detector with an audible and visual alarm, the present invention monitors gas concentrations in real time and issues audible and visual alarms promptly. Furthermore, the laser pointer guides evacuation, improving safety. A rotating mechanism ensures that the laser pointer points in the correct evacuation direction, providing more effective evacuation guidance in emergency situations.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0022] like Figures 1 to 2 As shown, an integrated wireless sound and light alarm 2 for a gas detector, wherein this embodiment includes a gas detector body 1, an sound and light alarm 2 and a laser indicator 5 for emitting laser indication light, and the gas detector body 1 includes a first shell 11, and a rotating mechanism 3 is provided between the first shell 11 and the sound and light alarm 2 for driving the sound and light alarm 2 to rotate circumferentially around the gas detector body 1, and the laser indicator 5 is installed at the end of the sound and light alarm 2 away from the first shell 11, and the rotating mechanism 3 can drive the laser indicator 5 to rotate to the correct orientation and point out the correct evacuation direction.

[0023] The gas detector body 1 of this embodiment includes a first shell 11, and a gas sensor and a control circuit board installed inside the first shell 11. The detector can monitor the gas concentration in the environment in real time, and when it detects excessive or harmful gases, it will emit sound and light alarms by controlling the sound and light alarm 2. The sound and light alarm 2 is installed on the side outer wall of the first shell 11, and a laser detector is provided at the end facing away from the detector. The laser detector can emit a laser beam with good penetration to form a directional light to guide people to move to the safe exit. In addition, a rotating mechanism 3 is provided between the sound and light alarm 2 and the gas detector body 1, which can make the sound and light alarm 2 rotate circumferentially relative to the gas detector to ensure that the laser indicator 5 is facing the correct side of the evacuation passage. Specifically, a plurality of networked smoke detectors are usually installed in a building, and the diffusion direction of the gas can be roughly determined by comparing the data between the sensors. That is, if multiple detectors in an area are triggered in sequence, the approximate location of the leak source can be inferred based on the triggering sequence.

[0024] like Figure 2 As shown, the rotating mechanism 3 of this embodiment includes a movable housing 31 that is sleeved on the outer wall of the first housing 11 and fixedly connected to the sound and light alarm 2, a driven gear 32 that is provided at one end of the movable housing 31 and plugged into the first housing 11, a driving gear 33 that is engaged with the driven gear 32, and a drive motor 34 for driving the driving gear 33 to rotate. The control mainboard 22 controls the drive motor 34 to rotate the driving gear 33 based on the evacuation direction and the current position of the sound and light alarm 2 provided by the position encoder, and drives the engaged driven gear 32 to rotate together, thereby driving the movable housing 31 to rotate around the outside of the first housing 11, so that the laser pointer 5 points to the correct direction.

[0025] like Figure 2 As shown, the sound and light alarm 2 of this embodiment includes a second housing 21, within which is disposed a control motherboard 22 electrically connected to the laser pointer 5. The control motherboard 22 also includes a wireless communication module for transmitting alarm information to a monitoring terminal. Wireless communication with terminal devices such as smartphones and computers can be achieved via wireless technology, enabling timely transmission of alarm information and remote control of the laser pointer 5 via the terminal.

[0026] like Figure 1 As shown, the sound and light alarm 2 of this embodiment also includes a speaker 23 for emitting an audible alarm and an alarm light 24 for emitting a visual alarm. Both the speaker 23 and the alarm light 24 are electrically connected to the control motherboard 22. Specifically, the speaker 23 is responsible for emitting a high-decibel audible alarm, while the alarm light 24 emits a visual alarm by flashing an LED light. These components are all electrically connected to the control motherboard 22. When the gas concentration is detected to exceed the safety threshold, the device emits a strong audible alarm through the speaker 23 and a flashing LED light through the alarm light 24, thereby achieving a dual sound and light alarm. This sound and light alarm method can effectively attract the attention of nearby personnel, ensuring that they can respond promptly and take appropriate safety measures.

[0027] like Figure 2 As shown, a battery compartment 4 is further provided within the second housing 21 of this embodiment. A backup power source 41 for powering the laser pointer 5 is provided within the battery compartment 4. The battery compartment 4 contains a battery assembly for providing backup power 41 for the laser pointer 5. The battery assembly can be a common dry cell battery, a rechargeable battery, or another type of battery, ensuring that the laser pointer 5 can continue to operate normally even if the main power source fails or is unavailable.

[0028] In summary, the beneficial effects of this embodiment are as follows: Through the design of the integrated wireless sound and light alarm 2, this embodiment can monitor gas concentration in real time and issue sound and light alarms in a timely manner, while using the laser pointer 5 to guide personnel evacuation, thereby improving safety. The rotating mechanism 3 ensures that the laser pointer 5 can point in the correct evacuation direction, thereby providing more effective evacuation guidance in emergency situations. The wireless communication module enables the alarm information to be transmitted to the monitoring terminal and remote equipment in a timely manner, facilitating the timely implementation of measures. The design of the backup power supply 41 ensures that the laser pointer 5 can still operate normally in the event of a main power failure, further improving the reliability of the system.

[0029] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
