Technical Field
[0001] The utility model relates to the technical field of central control modules, in particular to a central control module of a kitchen fire extinguishing system. Background Art
[0002] The kitchen fire extinguishing central control module is a device used to control the kitchen fire extinguishing system. It is usually composed of a central control host and some auxiliary equipment. It can monitor the fire condition in the kitchen and automatically trigger the fire extinguishing device. The central control module can receive signals from the fire detector. Once a fire is detected, it will immediately take corresponding measures to prevent the spread of the fire and reduce the losses caused by the fire.
[0003] Due to the high amount of oil smoke in the kitchen, temperature control is usually used to trigger the fire extinguishing device. The existing kitchen fire extinguishing master control module usually uses a disposable trigger device when sensing the temperature in the kitchen. The trigger device needs to be replaced after being triggered, which is very troublesome to use. For this reason, we propose a kitchen fire extinguishing system master control module.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1
[0027] See also Figure 1-8 The utility model provides a technical solution: a central control module of a kitchen fire extinguishing system, comprising a central control module body 1; a trigger mechanism 2, the trigger mechanism 2 is located inside the central control module body 1, and the trigger mechanism 2 can trigger the fire extinguishing system; a locking member 3, the locking member 3 is located inside the trigger mechanism 2, and the locking member 3 can lock the trigger mechanism 2. When the utility model is in use, the central control module body 1 can trigger the fire extinguishing system according to the excessive temperature inside the kitchen. When the temperature inside the kitchen is higher than the normal working temperature, the trigger mechanism 2 will trigger the fire extinguishing button. At this time, the central control module body 1 controls the kitchen fire extinguishing system to extinguish the fire inside the kitchen, which is safer to use. At the same time, it is equipped with an anti-mistouch device. When the trigger mechanism 2 is about to be triggered due to mistouch, vibration and other factors, the locking member 3 located inside the trigger mechanism 2 will lock the trigger mechanism 2 to avoid mistouch, which is more convenient to use.
[0028] The trigger mechanism 2 includes a trigger box 21 fixedly connected to the inside of the central control module body 1, a rotating rod 22 is rotatably connected to the inside of the trigger box 21, a rotating plate 23 is fixedly connected to the outer periphery of the rotating rod 22, a trigger button 24 is fixedly connected to the upper inner wall of the trigger box 21, one end of the rotating plate 23 corresponds to the position of the trigger button 24, a trigger member 4 capable of pressing the rotating plate 23 is provided above the end of the rotating plate 23 away from the trigger button 24, the trigger member 4 includes a trigger slot 41 opened above the trigger box 21, the trigger slot 41 is located at the end away from the trigger button 24, a support frame 42 is fixedly connected to the inside of the central control module body 1, the support frame 42 is located above the trigger slot 41, a plastic ball 43 is placed above the support frame 42, and paraffin 44 is provided inside the plastic ball 43.
[0029] When the kitchen temperature rises and is higher than normal working, the paraffin 44 located above the support frame 42 begins to melt. The melted paraffin 44 is in the plastic ball 43. The paraffin 44 changes from solid to liquid. The support frame 42 cannot support the plastic ball 43. The plastic ball 43 wraps the paraffin 44 and drips onto the rotating plate 23 through the trigger groove 41. The excessive weight of one end of the rotating plate 23 will drive the rotating rod 22 located inside the trigger box 21 to rotate, and the rotating plate 23 away from the end of the plastic ball 43 will be pushed up, thereby triggering the trigger button 24. The trigger button 24 is connected to the fire extinguishing system inside the central control module body 1 through a wire, which is not shown in the figure. After the trigger is completed and the kitchen temperature returns to room temperature, the paraffin 44 gradually solidifies, and the plastic ball 43 is taken out and turned over and placed above the support frame 42, and can continue to be used, thereby achieving the effect of no need for replacement, and it is very convenient to use and replace.
[0030] The locking member 3 includes a locking groove 31 opened in the center of the rotating plate 23, a locking box 32 is rotatably connected to the outer periphery of the rotating rod 22, the locking box 32 is fixedly connected to the inner wall of the trigger box 21, the locking box 32 is located in the locking groove 31 and is rotatably connected to the locking groove 31, a friction wheel 33 is fixedly connected to the outer periphery of the rotating rod 22, the friction wheel 33 is located inside the locking box 32, and a non-Newtonian fluid 34 is arranged inside the locking box 32. When the rotating plate 23 is accidentally triggered by accidental touch, vibration, etc., the rotating plate 23 is subjected to an instantaneous pressing force. Due to the non-Newtonian fluid 34, the rotating plate 23 is subjected to an instantaneous pressing force. The fluid 34 is a special fluid whose flow state and physical properties change under the action of an external force. The greater the force, the greater the resistance of the non-Newtonian fluid 34. On the contrary, the slower the force is applied, the smaller the resistance of the non-Newtonian fluid 34. When the rotating plate 23 quickly drives the rotating rod 22 to rotate, the friction wheel 33 located on the periphery of the rotating rod 22 stirs the non-Newtonian fluid 34 and rubs against the non-Newtonian fluid 34. The non-Newtonian fluid 34 locks the friction wheel 33 to prevent the rotating plate 23 from triggering the trigger button 24 and causing an accidental touch.
[0031] Embodiment 2
[0032] A magnet 5 is fixedly connected to one end of the trigger box 21 away from the trigger button 24. The magnet 5 is located inside the trigger box 21. The magnet 5 can adsorb one end of the rotating plate 23 away from the trigger button 24. A counterweight 6 is fixedly connected to one end of the rotating plate 23 away from the trigger button 24. When the calligraphy mechanism is in normal use, the magnet 5 adsorbs the rotating plate 23. At this time, the rotating plate 23 at the other end will not trigger the trigger button 24. When the indoor temperature rises and exceeds the normal kitchen temperature, the coercive force of the magnet 5 will change with the increase in temperature. The coercive force of the magnet 5 will decrease with the increase in temperature, and the magnetic force of the magnet 5 will weaken. The magnet 5 cannot adsorb the rotating plate 23. The counterweight 6 presses the rotating plate 23 to rotate, and the rotating plate 23 at the other end is lifted up and triggers the trigger button 24. The magnet 5 adsorption method does not require adjustment of the flipping of the plastic ball 43, which is more convenient to use.
