Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of alarm devices, in particular to a fireplace door un-closed alarm device. BACKGROUND

[0002] The safety and performance of a fireplace, as a common heating device, is of great importance. Whether the fireplace door is closed or not directly affects the normal operation of the device and the safety of the user. In particular, for fireplaces that use gas or wood as fuel, an un-closed door can cause flame leakage and other safety hazards such as fire.

[0003] The patent with patent number CN116092276B relates to the technical field of alarm devices. The rear side of each clamping plate is fixedly connected with two guide rods in a straight line array. The front end of the guide seat is installed with a smoke sensor, a camera, and a fill light in a straight line array. The patent solves the problem that the power distribution cabinet cannot be quickly isolated when an abnormality occurs during use, which can easily cause a chain reaction and damage to a large number of components inside the power distribution cabinet. The gas tank installed in the bracket is started to spray carbon dioxide through the nozzle to quickly protect the equipment, and the motor installed at the top of the moving seat is started to rotate the guide seat, which quickly isolates the abnormal equipment and protects the power distribution cabinet.

[0004] In the prior art, the fireplace door un-closed alarm device can control the alarm by setting a timing device to ensure that the alarm will start if the door is opened for too long, preventing toxic gas from leaking into the room and ensuring the safety of the occupants. However, the timing device cannot directly sense the actual state change of the device, and it can only rely on a pre-set time delay. This means that in some cases, the timing device may not be able to determine whether the door is closed in time, especially when operating quickly within a short period of time, which may result in false alarms or missed alarms. Since the timing device relies on a fixed time period, it may not be suitable for different door opening and closing speeds, or it may need to be adjusted frequently in some cases, increasing the complexity of use.
