Description

Technical Field

[0001] The invention relates to the technical field of alarm devices, in particular to an alarm device for a fireplace door not being closed. Background Art

[0002] As a common heating device, fireplace safety and performance are crucial. Whether the fireplace door is properly closed is directly related to the proper functioning of the device and the safety of the user. Especially for fireplaces fueled by gas or wood, an open door can cause flames to escape, creating safety hazards such as fires.

[0003] The patent announcement number CN116092276B relates to the technical field of alarm devices. The rear side of each splint is fixedly connected to two guide rods in a linear array, and the front end of the guide seat is installed with a smoke sensor, a camera and a fill light in a linear array. It solves the problem that it is mostly through sound and light alarms inside the distribution cabinet for prompts, but if an abnormality occurs during the use of the distribution cabinet, it is impossible to perform emergency isolation of the abnormal equipment in the distribution cabinet, and it is easy to cause a large number of components inside the distribution cabinet to be damaged due to a chain reaction. By starting the gas tank installed in the bracket, carbon dioxide is quickly sprayed on the retracted equipment through the nozzle for protection, and the motor installed on the top of the moving seat is synchronously started to drive the guide seat to rotate, and the guide seat is flipped to achieve rapid isolation of the abnormal equipment, thereby achieving the purpose of protecting the distribution cabinet body.

[0004] In existing fireplace door open alarm systems, while a timer can be set to control the alarm if the door is left open for too long, preventing toxic gases from leaking into the room and ensuring safety, the timer cannot directly sense actual changes in the device's state and relies solely on a preset time delay. This means that in some cases, the timer may not be able to determine whether the door has not been closed in time, especially during rapid operation, potentially leading to false or missed alarms. Because the timer relies on a fixed time period, it may not adapt to varying door opening and closing speeds, or in some cases, the delay setting may require frequent adjustment, increasing the complexity of use.

[0025] When the embodiment is working: when using the heater 1 for heating, it is necessary to put combustible materials such as ignited wood into the heater 1 to make a fire. When the combustible materials are burning, some toxic gases may be generated, and the toxic gases will be discharged to the outside through the ventilation pipe 2 and the outside air will be drawn into the heater 1 to help combustion. When it is necessary to add combustible materials to the inside of the heater 1, it is necessary to rotate the handle 4 to release the limit between the blocking door 3 and the heater 1, so that the blocking door 3 can be pulled to release the seal on the heater 1. When the blocking door 3 is not closed for a long time, the heater 1 will be blocked. The toxic gas inside the furnace 1 will gradually spread to the room and cause danger. When the barrier door 3 is not closed for a long time, the alarm 5 will start to sound to remind you to close the barrier door 3. When you need to add combustibles, turning the handle 4 will drive the pressure plate 12 to move. The pressure plate 12 moves and contacts the control end of the controller 13. The pressure plate 12 will push the control end of the controller 13 downward to energize the power supply and contact head 14.

When the sliding block 16 is in contact with the blocking door 3, the alarm 5 is connected to the power supply, and the alarm 5 emits a sound to remind. The automatic alarm when the blocking door 3 is not closed is realized through the mechanical linkage structure, and the poisonous gas is effectively prevented from leaking into the room.

[0031] When the present embodiment is working, when the blocking door 3 needs to be opened and the handle 4 is turned, the rotation of the handle 4 will drive the rotating plate 21 to rotate, and the rotation of the rotating plate 21 will push the sliding block 22 to move, and the movement of the sliding block 22 will push the connecting rod 23 to move, and the movement of the connecting rod 23 will push the slide plate 24 to move, and the movement of the slide plate 24 will push the connecting rod 1 25 to move, and the connecting rod 1 25 will push the push block 26 to move in the direction of the baffle 27, and the movement of the push block 26 will push the connecting rod 2 28 to move, and the movement of the connecting rod 2 28 will push the baffle 27 to move in the direction away from the ventilation pipe 2, so that the opening of the part connected between the ventilation pipe 2 and the heater 1 will be expanded, and the expansion of the opening will directly increase the exhaust rate of harmful gases, offset the risk of smoke escape at the moment of opening the door, and accelerate the exhaust rate of toxic gases, and synchronously expand the opening of the ventilation pipe 2 at the moment the blocking door 3 is opened, so that the exhaust rate of toxic gases is increased. A negative pressure barrier is formed to prevent smoke from diffusing into the room. The movement of the sliding block 22 will push the key 29 to move in the direction away from the rotating plate 21. When the sliding block 22 moves upward, it will drive the square groove to move. When the position of the square groove coincides with the key 29, the No. 3 spring will drive the key 29 to move in the direction of the square groove. Then, when the rotating plate 21 continues to rotate to release the contact with the inside of the sliding block 22, the key 29 will be inserted into the inside of the sliding block 22 to limit the sliding block 22. The surface sliding block 22 moves towards its original position after the barrier door 3 is opened, causing the baffle 27 to move back to its original position, thereby reducing the opening between the ventilation pipe 2 and the heater 1. After the key 29 is inserted, the baffle 27 is forced to remain away from the displacement end point of the ventilation pipe 2, and the ventilation pipe 2 opening remains expanded, ensuring that the smoke exhaust rate does not decay during the opening of the barrier door 3, avoiding the problem of the opening shrinking due to falling back due to gravity.

[0032] The movement of the baffle 27 will push the rotating rod 1 32 to move, the movement of the rotating rod 1 32 will push the telescopic rotating rod 31 to rotate, the rotation of the telescopic rotating rod 31 will pull the rotating rod 2 34 to move, the movement of the rotating rod 2 34 will push the sealing plate 1 33 to move away from the blocking door 3, the movement of the sealing plate 2 35 will drive the connecting rod 3 36 to move, the movement of the connecting rod 3 36 will drive the sealing plate 2 35 to move away from the sealing plate 3 37, the movement of the sealing plate 2 35 will drive the lifting rod 38 to move, and the movement of the lifting rod 38 will release the sealing plate 2 35. In addition to lifting the sealing plate 3, the sealing plate 3 will move downward, so that when the barrier door 3 is opened to add materials, the sealing plate 3 and the sealing plate 2 will not cause obstruction, avoiding damage to the sealing plate 3 and the sealing plate 2 when discharging materials. When the combustible material is added and the barrier door 3 is closed, the baffle 27 will move toward the original position, and the movement of the baffle 27 will pull the rotating rod 1 32 to move, and the movement of the rotating rod 1 32 will pull the telescopic rotating rod 31 to move toward the original position, and the sealing plate 1 33 will move toward the original position. When the sealing plate 1 33 is reset, the sealing plate 2 35 will move toward the sealing plate 3 37, and the sealing plate 2 35 will drive the lifting rod 38 to move, and the lifting rod 38 will lift the sealing plate 3 37, so that the sealing plates 1 33, 2 35 and 37 will strengthen the sealing between the barrier door 3 and the interior of the heater 1. Through the mutual cooperation between the three sealing plates, the dead corners inside the heater 1 can be sealed, reducing the leakage of toxic gases, enhancing the safety of the equipment, and sealing. The movement of plate 2 35 will drive the pressure block 39 to move, and the movement of pressure block 39 will contact the inclined surface of the blocking plate 391, so that the pressure block 39 will push the blocking plate 391 to move toward the rotating plate 21, and the blocking plate 391 will fit with the rotating plate 21, increasing the resistance when the rotating plate 21 rotates, preventing the handle 4 from rotating downward due to gravity problems. The blocking plate 391 can eliminate the risk of spontaneous rotation of the handle 4, so that the limit between the barrier door 3 and the heater 1 will not contact at will, thereby preventing gas leakage inside the heater 1.
