[0002] As people's fire awareness increases, they pay more and more attention to fire safety. Smoke alarms, as an important part of fire warning equipment, use photoelectric smoke sensors inside, which can accurately detect smoke generated by fires. They are currently widely used in shopping malls, hotels, shops, warehouses, computer rooms, residences and other places for fire warning broadcasts.

[0003] Currently, property management personnel's daily firefighting work includes regularly testing smoke alarms with a small amount of smoke to ensure that the photoelectric smoke sensor inside the smoke alarm is functioning properly. When the smoke alarm is triggered by smoke, its internal buzzer will emit a piercing alarm sound to achieve the desired warning effect. However, after completing the smoke test, the existing smoke alarm is in a high position, making it difficult for property management personnel to turn off the buzzer in time. This not only easily affects other people nearby, but also increases the power consumption of the smoke alarm. Therefore, the present invention proposes a smoke alarm that is easy to control. Summary of the Invention

[0004] The utility model provides a corridor smoke alarm which adopts a novel button structure to solve the control problem of the buzzer.

[0005] The purpose of this utility model is achieved by the following methods:

[0006] The corridor smoke alarm includes a protective shell and an early warning module. A cavity for accommodating the early warning module is provided in the protective shell. The outer wall of the cavity is surrounded by an entrance connected to the outside. The early warning module includes a main control circuit board, a smoke sensor and a buzzer. A button is provided on the main control circuit board. A pressing piece for abutting against the button is retractably provided at the bottom of the protective shell. The bottom of the pressing piece is provided with a force-bearing part covering the bottom of the protective shell.

[0007] Furthermore, the outer edge of the pressing member is provided with a limiting protrusion for snap-fitting with the protective shell.

[0008] Furthermore, a light-transmitting plate is provided in the middle of the pressing member, and an indicator light electrically connected to the main control circuit board is provided above the light-transmitting plate.

[0009] Furthermore, a protection grille is provided in the protection shell and surrounds the outside of the smoke sensor.

[0010] Furthermore, the protective shell is composed of a main body and a cover plate, and the cover plate is installed on one side of the main body through threads or screws.

[0011] Furthermore, the protective shell is installed through a limiting card plate, a limiting card slot is provided on the limiting card plate, the upper end of the cover plate is provided with a card position for slidingly fitting with the limiting card slot, and card slots that can pass through the card position are symmetrically provided on both sides of the limiting card slot.

[0012] Furthermore, a limiting block protruding upward is provided in the middle of the limiting slot, and the limiting slot is formed between the limiting block and the limiting card plate.

[0013] Furthermore, the middle portion of the position-limiting card plate is tilted upward, so that a cavity is formed between the lower end of the position-limiting card plate and the upper end of the cover plate.

[0014] Furthermore, a protective edge is provided around the outer edge of the limiting clamping plate.

[0015] This new corridor smoke alarm utilizes a push-button mechanism covering the bottom of the protective housing in conjunction with a button on the main control circuit board, enabling convenient control of the buzzer. After a simulated test of the smoke alarm, a property management employee, even if they are shorter than a man, can use the external stick structure to press the force-bearing portion. This allows the buzzer to be quickly deactivated through the contact between the push-button and the button. This effectively avoids the difficulty of traditional smoke alarms in shutting off when in a high position, reducing unnecessary noise interference and power consumption. The force-bearing portion covering the bottom of the protective housing reduces the difficulty of finding and aligning the button, facilitating rapid deactivation of the buzzer.
