Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fans, and more specifically, to an intelligent control unit for a fire exhaust fan. Background Technique
[0002] As an important fire-fighting equipment, the fire exhaust fan plays a key role in exhausting smoke and ventilating in case of emergencies such as fires. However, traditional fire exhaust fans mainly focus on the smoke exhaust function and do not have the ability to purify soot, and cannot effectively filter harmful substances in the flue gas. To a certain extent, this limits its application effect in complex environments. In recent years, although some fans have begun to be equipped with filter components in an attempt to solve the problem of soot purification, these filter components are often cumbersome to install and disassemble, which not only increases the maintenance cost but also affects the usability of the fan. More critically, over time, the soot on the filter screen will gradually accumulate, resulting in the blockage of the filter screen pores and a significant decrease in the smoke exhaust effect.
[0003] More severely, there is currently a lack of effective detection means for the filtration effect of exhaust fans in the market. This leads to the situation that users can often only discover problems after the smoke exhaust effect has significantly deteriorated. At this time, the common countermeasure is to increase the exhaust air volume and exhaust power. This approach not only wastes energy but also easily burns out the fan during long-term high-load operation, further increasing the potential safety hazards and maintenance costs.

The present invention will be further described in conjunction with the drawings and embodiments:
[0024] As Figures 1-4 shown, an intelligent control unit for a fire smoke exhaust fan includes a fire duct 1. The fire duct includes a bottom plate 102, a top plate 101, a left plate 103 and a right plate 104. The top plate and the bottom plate are connected together by the left plate and the right plate. A clamping groove 13 is provided at the bottom of the bottom plate, and an insertion interface 12 is formed in the clamping groove.

Such a design makes the installation of the smoke exhaust fan more convenient and improves the installation efficiency and maintenance convenience. A smoke exhaust fan 3 is inserted into the insertion interface. A fixing plate 31 is provided at the bottom of the smoke exhaust fan. When the top of the smoke exhaust fan is clamped in the upper socket, the fixing plate is in the clamping groove and is fixedly connected to the bottom plate by a bolt 37. Such a connection method is both stable and reliable, ensuring the stability and safety of the smoke exhaust fan during operation. A filter assembly 2 is inserted into the fixing plate. An installation notch 14 is provided at the bottom of the top plate, and a permanent magnet 15 is provided in the installation notch. The top of the filter assembly is magnetically attracted to the permanent magnet. The magnetic attraction design makes the replacement of the filter assembly more convenient and improves the maintenance efficiency and convenience.
[0025] In at least one embodiment, the filtering component includes a filtering frame, and a filter screen is arranged inside the filtering frame, which is used to effectively filter smoke and dust, improving the filtering effect and service life of the exhaust fan. A connecting plate 21 is arranged at the bottom of the filtering frame, and a pull ring 22 is arranged at the bottom of the connecting plate. The design of the pull ring makes the disassembly of the filtering frame more convenient, facilitating the user to replace and clean it.
[0026] Furthermore, a first through groove 16 for the filtering frame to pass through is arranged on the bottom plate. Such a design makes the installation and disassembly of the filtering frame smoother, avoiding damage caused by improper installation or disassembly.
[0027] Furthermore, a second through groove 33 for the filtering frame to pass through is arranged on the fixing plate.
[0028] Furthermore, a mating notch 34 is arranged at the bottom of the second through groove, a connecting plate is inserted into the mating notch, and an elastic limiting block 35 is formed in the mating notch. When the connecting plate is inserted into the mating notch, the elastic limiting block can limit the connecting block from disengaging from the mating notch. Such a design not only ensures the stable installation of the filtering frame, but also facilitates the disassembly and replacement by the user, improving the practicability of the product and the user experience.
[0029] Furthermore, a magnetic iron sheet matching with the permanent magnet is arranged at the top of the filtering frame, enhancing the magnetic attraction between the filtering component and the top plate, making the filtering component more stable after installation and not easy to fall off.
[0030] In at least one embodiment, a through hole 36 is arranged on the fixing plate, and the bolt passes through the through hole and is threadedly connected to the threaded hole 17 on the bottom plate. Such a connection method is simple and reliable, ensuring the stable connection between the fixing plate and the bottom plate.
[0031] In at least one embodiment, an air volume sensor 38 is installed on the fixing plate, and the end of the air volume sensor penetrates through the fixing plate and the bottom plate and extends into the fire fighting air duct, for real-time monitoring of the air volume change, improving the intelligent level and safety of the fire fighting exhaust system.
[0032] In a refined solution, the air volume sensor is located on the side of the exhaust fan away from the filtering component. Such a design avoids the influence of the filtering component on the air volume sensor, improving the accuracy and reliability of the air volume measurement.
[0033] In at least one embodiment, a limiting mechanism is arranged at the bottom of the fixing plate, and the limiting mechanism can limit the connecting block from disengaging from the mating notch.
[0034] Specifically, the limiting mechanism includes a socket 41. The socket 41 is provided on the fixing plate. A plug board 42 is slidably fitted in the socket. A pull plate 43 is provided at the end of the plug board. A flexible spring 44 is provided between the pull plate and the socket. The flexible spring urges the plug board to be directly below the connecting plate. Such a design not only ensures the stable installation of the filter frame but also facilitates the disassembly and replacement by the user, further improving the practicality of the product and the user experience.
[0035] Working method: Ensure that all components of the intelligent control unit of the fire smoke exhaust fan are complete, including the fire duct, smoke exhaust fan, filter component, fixing plate, bolts, etc. Check whether each component is intact, especially the filter net and magnetic iron sheets. Snap the top of the smoke exhaust fan into the upper socket on the top plate of the fire duct. Align the fixing plate at the bottom of the smoke exhaust fan with the clamping groove on the bottom plate and insert it into the insertion opening. Use bolts to fix the fixing plate to the bottom plate to ensure a firm connection. Pass the filter frame of the filter component through the first through groove on the bottom plate and the second through groove on the fixing plate. Ensure that the magnetic iron sheet on the top of the filter frame is magnetically attracted to the permanent magnet at the bottom of the top plate to fix the filter component. If there are elastic limit blocks or limiting mechanisms, ensure that they can prevent the connecting plate from disengaging from the mating notch.
[0036] Connect the wires of components such as the smoke exhaust fan and air volume sensor to the wiring terminals of the control board to ensure a firm and good contact. Configure the control board and set parameters such as the warning value of the air volume sensor to ensure that the control board can accurately monitor the working state of the smoke exhaust fan and the data of the air volume sensor. After completion of assembly and wiring, conduct a function test to ensure that the smoke exhaust fan, filter component, and air volume sensor can all work normally, and the control board can accurately monitor and alarm. Put the intelligent control unit of the fire smoke exhaust fan into actual use. Control the start and stop and working mode of the fan through the control board, and the filter component is responsible for filtering smoke and dust.
[0037] During normal use, the smoke exhaust fan will work to discharge smoke or harmful gases. The filter component will filter out impurities or particulate matter entering the fire duct to keep the duct clean and unobstructed. The air volume sensor will continuously monitor the air volume in the fire duct and provide data for the control system to analyze or alarm. When the air volume sensor detects that the air volume is gradually decreasing, the control board will obtain the data in real time and make a comparison to determine whether the preset warning value is reached. If the air volume decreases below the warning value, the control board will immediately trigger the alarm or warning light to emit an obvious alarm signal to remind people to come and replace the filter component in time. When replacing the filter component, simply disconnect the magnetic connection gently and then take out the filter frame from the through groove for replacement. The operation is simple and fast.
