Description

Technical Field

[0001] The present application relates to the technical field of fire alarms, and in particular to a reusable manual fire alarm device. Background Art

[0002] Fire alarms are essential alarm devices in many occasions, such as large venues, public transportation, schools, supermarkets and other public places and private residences. When a fire occurs in these places, pressing the manual fire alarm in time can save lives and ensure property safety to a great extent.

[0003] At present, the manual fire alarm on the market usually has a fragile component, which needs to be broken to operate the release component to alarm. After the alarm is released, the alarm needs to be replaced or at least the broken fragile component needs to be replaced before it can be used again. On the one hand, it is inconvenient to test the manual fire alarm before use to ensure that it functions normally and can alarm, and on the other hand, the one-time cost is high. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing manual fire alarm is inconvenient to test before use, and the cost of use is high. To this end, the utility model provides a reusable manual fire alarm device. After the alarm is released, it is only necessary to pull the anti-reset baffle to unlock it, and the fire alarm device can be reused after the trigger device is reset. Using the reusable manual fire alarm device of the present application can save the replacement of broken and fragile components after the alarm is used, thereby saving the cost of use. At the same time, because its test does not require damage to any components, the function of the fire alarm device can be repeatedly tested before use to ensure that its circuits, switches, indicator lights, etc. are working properly.

[0005] In order to solve the above technical problems, the utility model provides a reusable manual fire alarm device including an alarm base, a trigger device and a locking device. The alarm base includes a touch switch, the locking device includes an anti-reset baffle for locking the trigger device, one end of the anti-reset baffle is connected to the alarm base in a planar swingable manner, and the anti-reset baffle is on one side above the touch switch and has a tendency to move to the other side.

[0006] When the trigger device is manually pressed, the trigger device presses the touch switch to activate the alarm. At the same time, the anti-reset barrier bars jam the trigger device so that even if no one presses the alarm, the trigger device can remain pressed down, the touch switch remains on, and the alarm continues to sound.

[0007] When the alarm is lifted, the anti-reset baffle bar only needs to be moved to release the lock on the trigger device, and the alarm can be reset and wait for use again.

[0008] Furthermore, as one of the preferred modes of the reusable manual fire alarm device: the locking device also includes a spring with one end fixed to the base of the alarm, the other end of the spring is connected to the middle of the anti-reset bar, and the spring is in a relaxed state. When the trigger device is pressed, the anti-reset bar, due to the spring and the limit protrusion structure, slightly gives way to the T-shaped protrusion on the trigger device, and then immediately returns due to the spring tension to lock the T-shaped protrusion, so that the trigger device cannot rebound and remains in a pressed state.

[0009] Further, as one of the preferred modes of the reusable manual fire alarm device: the base of the alarm has a cavity, the cavity is provided with a controller, the controller is connected to a touch switch, the front of the base of the alarm has a first opening, the first opening exposes the touch switch. The controller contains relatively sophisticated electronic components, communication components, circuit components, etc., and does not need to be reset by toggling. The controller is wrapped in a relatively closed cavity of the base of the alarm, and only the touch switch is exposed, which can play a protective role.

[0010] Furthermore, as one of the preferred forms of a reusable manual fire alarm device: the trigger device includes a pressure plate hinged on the alarm base, the pressure plate can be flipped to cover the front of the alarm base, a T-shaped protrusion is provided on the back of the pressure plate facing the touch switch, the two side surfaces of the lower end of the T-shaped protrusion are inclined surfaces, the anti-reset baffle bar is against the inclined surface of the T-shaped protrusion edge, and after the pressure plate is pressed down, the anti-reset baffle bar can lock the T-shaped protrusion.

[0011] After the pressure plate is pressed, the lower end of the T-shaped protrusion is inclined against the side of the anti-reset baffle and pushes it apart. After the T-shaped protrusion contacts the touch switch and is pressed, the anti-reset baffle is separated from the inclined surface and pressed against the upper end of the T-shaped protrusion to limit it. The T-shaped protrusion acts as a limiting structure and cooperates with the anti-reset baffle to lock the pressure plate so that it does not rebound. In addition, the simple locking structure can be easily unlocked by external force in the correct direction.

[0012] Furthermore, as one of the preferred modes of a reusable manual fire alarm device: the alarm base is also provided with a limit protrusion, and the limit protrusion limits the movement position of the anti-reset baffle bar to ensure that the lower end inclined surface contacts and can push the anti-reset baffle bar when the T-shaped protrusion is pressed down.

[0013] Furthermore, as one of the preferred modes of the reusable manual fire alarm device: a status indicator light is also provided in the cavity of the alarm base, and the status indicator light extends from the second opening of the alarm base. The status indicator light is connected to the controller, and can reflect whether the alarm has a fault by turning on and off and the color.

[0014] Furthermore, as one of the preferred embodiments of the reusable manual fire alarm device: the reusable manual fire alarm device further comprises a panel, the panel is fixed to the alarm base, and the panel is provided with openings for respectively exposing the trigger device and the status indicator light. The panel protects the internal structure of the alarm and also has an aesthetic effect.

[0015] Furthermore, as one of the preferred modes of the reusable manual fire alarm device: the panel is also provided with an opening for moving the anti-reset baffle. The anti-reset baffle can be unlocked by moving the anti-reset baffle from the opening, so that the alarm device can be reused. On the other hand, the panel can also limit the exposure of the anti-reset baffle, so that it is not easy to be accidentally touched to reset and release the alarm.

[0016] In summary, the advantages of the utility model are: after using the utility model, to release the alarm, you only need to pull the anti-reset baffle to unlock it, and the fire alarm device can be reused after the trigger device is reset. Its benefits are: (1) The alarm can be reused without replacing broken fragile components after use, thereby saving use costs. (2) Because its test does not require any damage to any components, the function of the fire alarm device can be repeatedly tested before use to ensure that its circuits, switches, indicator lights, etc. are working properly.
