TECHNICAL FIELD

[0001] The utility model relates to the technical field of alarm, specifically, one kind is carbon monoxide detection alarm. BACKGROUND

[0002] The working principle of carbon monoxide detection alarm is mainly based on the reaction between it and specific chemicals. Inside the alarm, there is a sensor, which is usually composed of two electrodes and an electrolyte. When carbon monoxide gas enters the sensor, it reacts with the chemicals in the electrolyte, generating an electric current. The size of this current is directly proportional to the concentration of carbon monoxide, that is, the higher the concentration of carbon monoxide, the greater the current generated. The circuit inside the alarm detects the size of this current and converts it into a corresponding electrical signal. When the concentration of carbon monoxide exceeds the preset safety threshold, the alarm will sound and light, reminding people to take timely measures.

[0003] The existing device has some drawbacks in the process of use, for example: the traditional installation method often involves a large number of screws and fasteners. When these safety monitoring devices need to be maintained or components are replaced, the traditional fastening method often requires the use of special tools for disassembly, which not only increases the complexity and time-consuming of installation, but also reduces the maintainability of the device in emergency situations.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example

[0021] like Figures 1-5 As shown, this utility model provides a technical solution: a carbon monoxide detector alarm, including a bottom cover 4, a first self-tapping screw 3, a second self-tapping screw 5, and a top cover 9. The bottom cover 4 and the top cover 9 are detachably fixed together by the first self-tapping screw 3. A PCB board 6 is fixedly installed on the inner side wall of the top cover 9 by the second self-tapping screw 5. A battery 11 is fixedly installed on the side of the PCB board 6 near the bottom cover 4. A buzzer 7 is glued to the side wall of the PCB board 6 near the top cover 9. A carbon monoxide sensor 12, a switch button 10, and an indicator light transmittance sheet 8 are fixedly installed on the side wall of the PCB board 6 near the top cover 9. A panel cover 1 is detachably fixed on the side of the bottom cover 4 away from the top cover 9. In actual use, the battery 11 serves as the power source for the alarm, providing power support for the entire system. The carbon monoxide sensor 12 is used to detect the carbon monoxide concentration in the environment. The switch button 10 is used to control the on / off state of the alarm. The indicator light 8 is used to display the working status of the alarm. The buzzer 7 is used to sound an alarm when the carbon monoxide concentration exceeds the standard. After the electronic components are installed, the PCB board 6 is fixed to the top cover 9 using the second self-tapping screw 5. After the alarm is installed, turn on the switch button 10, and the alarm will start working. The carbon monoxide sensor 12 will continuously detect the carbon monoxide concentration in the environment. When the detected carbon monoxide concentration exceeds the preset safety value, the PCB board 6 will control the buzzer 7 to sound an alarm. This alarm detects the carbon monoxide concentration in the environment in real time through the carbon monoxide sensor 12. Once the concentration exceeds the standard, it will immediately sound an alarm, effectively preventing carbon monoxide poisoning accidents.

[0022] As one implementation method in this embodiment, such as Figure 2 and Figure 5As shown, two mounting holes 101 are symmetrically arranged on the top of the panel cover 1, and expansion screws 2 are inserted into the inner sides of the two mounting holes 101, so that the panel cover 1 is fixed to the area to be installed by the expansion screws 2. The inner walls of the opposite sides of the bottom cover 4 are provided with mounting slots 401, and the outer walls of the opposite sides of the panel cover 1 are provided with guide insertion blocks 102 matched with the mounting slots 401. In the specific use process, first, the panel cover 1 is fixed to the area to be installed (such as a wall surface) by the expansion screws 2, and then the mounting slots 401 on the bottom cover 4 are inserted into the guide insertion blocks 102 on the panel cover 1, so that the bottom cover 4 is fixed to the panel cover 1. The bottom cover 4 is installed by cooperating with the guide insertion blocks 102 on the panel cover 1 through the mounting slots 401, without the need for additional screws or fasteners, greatly simplifying the installation process and improving the installation efficiency. When maintenance or replacement of components is required, the bottom cover 4 can be separated from the panel cover 1 through simple plug-in and plug-out operation, facilitating inspection and maintenance of internal components.

[0023] As an embodiment in the present embodiment, as shown in Figure 1 and Figure 3 As shown, the upper cover 9 is provided with an induction port 901, a plurality of light transmission ports 902, a switch hole 903 and a sound transmission port 904. The induction port 901 is arranged to allow the induction end of the carbon monoxide sensor 12 to pass through the upper cover 9. The switch hole 903 is arranged to allow the switch button 10 to protrude. The sound transmission port 904 is arranged to facilitate the transmission of alarm sound. The light transmission port 902 is arranged to facilitate intuitive observation of the light flashing of the indicator light transmission sheet 8.

[0024] As an embodiment in the present embodiment, as shown in Figure 4 As shown, the side wall of the panel cover 1 away from the bottom cover 4 is provided with a guide mark 103, so as to avoid the installation direction of the panel cover 1 being reversed.

[0025] As an embodiment in the present embodiment, as shown in Figure 4 and Figure 5 As shown, the bottom cover 4 is symmetrically provided with a heat dissipation port 402 on the two sides. The design of the heat dissipation port 402 allows the heat generated inside the alarm to be more effectively dissipated to the external environment, thereby preventing internal components from being damaged or performance declining due to overheating, which is crucial for ensuring the long-term stable operation of the alarm.

[0026] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
