Description

Technical Field

[0001] The utility model relates to the technical field of smoke detectors, in particular to a smoke detector for fire fighting. Background Art

[0002] Fire smoke detectors, also known as fire smoke detectors or smoke fire detectors, are devices that prevent fires by monitoring smoke concentrations. Once the smoke concentration is detected to exceed the set value, the detector will sound an alarm to remind people of possible dangers, thereby preventing and promptly discovering fires. They are widely used in fire alarms in homes, shops, dance halls, warehouses and other places. They are an indispensable part of indoor fire prevention, allowing people to hear fire warning sounds and see fire signals in the first place, so that they can take appropriate escape and fire-fighting measures.

[0003] Patent document CN217333458U discloses a smoke detector for building fire safety, which discloses "including a smoke detector shell, the top of the smoke detector shell is connected to a mounting base, the mounting base has two limit grooves opening downward, the limit grooves are located on two opposite sides of the mounting base, the side walls of the limit grooves are provided with limit card slots connected thereto, the top of the smoke detector shell is connected to a mounting shell, the mounting shell is externally connected to a retractable shell that can be plugged into the limit card slot, and also includes a power component for driving the retractable shell to achieve retraction; the smoke detector for building fire safety disclosed by the utility model has the effect of easy disassembly and assembly and convenient use".

[0004] However, the smoke detector for building fire safety in the above-mentioned public document mainly considers the effects of easy disassembly and assembly, and easy use, but is not convenient for quickly absorbing the air in the environment, so that the smoke detector can quickly detect the smoke. When a fire occurs in the room, the smoke needs to drift upward and enter the smoke detection shell before the smoke can be detected. It takes a certain amount of time for the smoke to drift, and during this time, the fire may gradually increase.

[0005] In view of this, it is necessary to develop a rapid detection mechanism that can quickly adsorb the air in the environment so that the smoke detector can quickly detect the smoke. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is equipped with a rapid detection mechanism to quickly absorb the air in the environment, so that the smoke detector can quickly detect the smoke. When a fire occurs in the room, the smoke needs to drift upward and enter the smoke detection shell before the smoke can be detected. It takes a certain amount of time for the smoke to drift, and during this time, the fire may gradually increase. Therefore, it is necessary to improve it so that the air in the environment can be quickly absorbed, so that the smoke detector can quickly detect the smoke, so that the fire can be discovered in time, and the staff can be reminded to respond quickly. When the fire protection installation shell is installed, the spacing column can prevent the rapid detection shell from directly contacting the wall. In the case where the circulation slot is blocked, the adsorption fan works to adsorb the air in the room through the adsorption holes. When there is a large amount of smoke in the room, the smoke can be quickly detected by the smoke sensor to issue an alarm. At the same time, the adsorbed smoke is filtered by the activated carbon plate, which also has a certain purification effect. The filtered smoke is then discharged through the circulation slot. When the activated carbon plate is used for a long time, the activated carbon plate can be pulled through the replacement slot and taken out from between the two groups of limiting blocks, and then disassembled and replaced. The rapid detection mechanism is used to quickly adsorb the air in the environment, so that the smoke detector can quickly detect the smoke, avoiding the situation where the fire gradually increases and causes serious losses.

[0017] 2. The utility model is equipped with an adjustment mechanism to adjust the distance of the smoke detection shell, and the smoke detection shell is easy to disassemble and replace. Due to the different terrains in the room, the position of the smoke detection shell is also adjusted accordingly, so that the smoke detector can detect smoke more accurately. In this case, it is necessary to facilitate the adjustment of the height of the smoke detection shell. First, the smoke detection shell is installed, and the locking shaft and the elongated locking block are inserted into the elongated locking groove. Then, the locking motor drives the elongated locking block to rotate, so that the elongated locking block and the elongated locking groove are in a misaligned state, and the anti-shake block fits with the outer wall of the locking motor to prevent the smoke detection shell from shaking, so that the connecting plate and the smoke detection shell are connected. According to needs, the electric pole is adjusted to drive the connecting plate to move, and the movement of the connecting plate drives the position of the smoke detection shell to move. At the same time, the smoke detection shell can also be disassembled, so that the position can be accurately adjusted to different terrains, thereby improving the practicality of the smoke detector.
