An internal thread is provided on the inner wall of the installation box 9 and is correspondingly screwed to the external thread seat; the battery box 11 supplies power to the device, and the piezoelectric alarm 13 adopts the piezoelectric alarm product of the Maxing brand. It has the characteristics of loud sound and low energy consumption, and can effectively sound an alarm when a fire occurs. The ion smoke detector 12 uses the TYCO brand MF301 ion smoke detector, which has high sensitivity and can quickly and accurately detect smoke and trigger an alarm in time. The protective filter block 8 is connected to the installation box 9 through threads, which is convenient for disassembly, cleaning or replacement, ensuring the normal working environment of the internal components and improving the operating stability of the device; the buckle assembly includes a plurality of pressing blocks 5 evenly distributed on the outer wall of the mounting seat 3, and the mounting seat 3 is provided with a pressing block 5 The card slot 10 has an L-shaped cross-section, a reset groove is provided on one side of the card slot 10, a spring 14 is provided in the reset groove, a reset plate is provided at one end of the spring 14, the reset plate is fixedly connected to the pressing block 5, and a plurality of snap-on buckles 15 corresponding to the card slot 10 are provided on the bottom surface of the protective cover 1; pressing the pressing block 5 can make the snap-on buckles 15 detach from the card slot 10, and the protective cover 1 can be easily removed, and the reset effect of the spring 14 facilitates the subsequent reinstallation of the protective cover 1, which greatly improves the convenience of maintenance, and the structure of the entire snap assembly is simple and reliable, ensuring the convenient disassembly and firm installation of the protective cover 1.

[0021] In the utility model, the snap-on buckle 15 is snapped into the corner of the inner top surface of the card slot 10; this snap-on method allows the protective cover 1 to be firmly installed, ensuring that the protective cover 1 will not fall off accidentally during normal use of the device, thereby improving the stability and reliability of the device. Even in a complex environment or when subjected to a certain vibration, the protective cover 1 can be firmly in place to ensure the safety of internal components; an alarm light 4 is extended on the outer wall of the installation box 9, and a through hole is opened on the top surface of the protective cover 1 for extending the alarm light 4; the alarm light 4 emits a warning light outward through the through hole on the protective cover 1, and cooperates with the sound alarm of the piezoelectric alarm 13 to achieve a dual sound and light alarm, thereby enhancing the alarm effect and being able to be used in different In order to attract people's attention in a certain environment, the selected LED alarm light 4 has high luminous efficiency and long service life, and can continuously and stably emit eye-catching light source; a plurality of through grooves 6 are provided on the top surface of the protective cover 1, and the through grooves 6 are arranged in a cross shape, and the through grooves 6 are closer to the center position with the center of the top surface of the protective cover 1 as the reference, and the size of the through grooves 6 is smaller; the design of the through grooves 6 not only ensures sufficient ventilation to allow smoke to enter the device and be sensed by the ion smoke detector 12, but also blocks the entry of larger particles of impurities, protects internal components, and improves the protection performance of the device and the accuracy of fire detection. The reasonable layout and size design of the through grooves 6 optimizes the smoke entry path, and effectively resists interference from external impurities.

[0022] Working principle: When the utility model is used, when it is necessary to maintain the inside of the device, the staff presses the pressing block 5 on the outer wall of the mounting seat 3. After the pressing block 5 is subjected to force, it is connected to the reset plate and moves in the reset groove, compressing the spring 14 in the reset groove. At the same time, the pressing block 5 pushes out the snap-on buckle 15 connected to the bottom surface of the protective cover 1, so that the snap-on buckle 15 is separated from the L-shaped snap-on groove 10 on the mounting seat 3, and the staff can easily remove the protective cover 1; after the maintenance work is completed, release the pressing block 5, and under the elastic action of the spring 14, the reset plate drives the pressing block 5 back to the initial position, and the snap-on groove 10 returns to its original state, preparing for the next installation of the protective cover 1. During the maintenance process, the staff can also manually rotate the protective filter block 8. Because its bottom end is provided with an external thread seat which is screwed correspondingly to the internal thread on the inner wall of the installation box 9, the protection filter block 8 can be removed from the installation box 9 by rotation, which is convenient for the inspection, cleaning or replacement of key components such as the internal battery box 11 and the ion smoke detector 12; the top surface of the protection cover 1 is arranged in a cross shape and the through groove 6 with its top surface center as the reference, the smaller the size is towards the center position, when smoke is generated in the building, the smoke can pass smoothly into the interior of the device and reach the ion smoke detector 12 to be sensed. At the same time, due to its special arrangement and size design, larger particles of impurities are difficult to enter, which plays a protective role, ensuring that the key components inside the device are not disturbed by external impurities and maintain stable operation; at this point, the use of the device is completed.
