Description

Technical Field

[0001] The present invention belongs to the technical field related to air purification, and more specifically, particularly relates to a digital new exhaust fan group intelligent connection system and a control method thereof. Background Art

[0002] With people's growing concern about indoor air quality, traditional ventilation systems can no longer meet the needs of modern buildings for health, energy saving and intelligence. Traditional new exhaust systems mostly rely on manual adjustment or simple timer switch control, lacking the ability to monitor and respond to indoor environmental parameters in real time, resulting in energy waste and poor indoor air quality. As more and more public places pay attention to public environmental safety, the quality of outdoor air environment becomes even more important, especially in hospitals, garbage disposal rooms and other places where indoor air pollution is serious. If indoor air is discharged to the outdoor environment without treatment, various indoor odors, even viruses and bacteria may be discharged into the outdoor public environment, which is a great threat to outdoor personnel. In order to protect our living environment, the purification of indoor air emissions is becoming more and more important, and the air purification in the existing technology has the following defects: In the existing technology, the digital new exhaust fan unit intelligent connection system simply discharges indoor air to the outside, and cannot filter the discharged indoor air, nor can it purify and filter the inhaled air. In particular, hospitals, garbage disposal rooms and other places with serious indoor air pollution, if the indoor air is discharged to the outdoor environment without treatment, various indoor odors, even viruses and bacteria may be discharged into the outdoor public environment, which is a great threat to outdoor personnel. In order to protect our living environment, the purification of indoor air emissions is becoming more and more important; In the prior art, when the filter components in the digital new exhaust fan intelligent connection system work for a long time, the filter components will age or be clogged by a large amount of impurities, which will cause the filtering effect of the filter components to be greatly reduced. In addition, the filter components are mostly designed as an integrated unit. When one part of the filter component is damaged, the entire filter component needs to be replaced, which greatly increases the cost of use.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a digital new exhaust fan unit intelligent connection system and a control method thereof. Through the arrangement of a guide block, a push rod, a movable plate and a spring, the two push rods and the movable plate move radially back and forth under the guiding action of the guide block and the elastic force of the spring. The radial back and forth movement of the two movable plates drives the elastic filter screen to move back and forth, so as to facilitate shaking and mixing of the activated carbon. Moreover, the positions at which one end of the two push rods contacts the outer side of the guide block are different, so that the positions at which the two push rods drive the movable plates to move are different, so that the back and forth movement of the two sides of the elastic filter screen is different, thereby improving the effect of shaking and mixing the activated carbon. Through the setting of the first protrusion and the second protrusion, one end of the push rod is in sliding contact with the outer side of the first protrusion, so that under the guiding action of the first protrusion, the push rod and the movable plate are pushed to move radially inward; and one end of the push rod is in sliding contact with the outer side of the second protrusion, so that under the guiding action of the second protrusion, the push rod and the movable plate are pushed to move radially inward; because the outer diameter of the first protrusion is greater than the outer diameter of the second protrusion, the degree of radial inward movement of the push rod and the movable plate is different, so that the two push rods and the movable plate can further move back and forth radially, improve the radial back and forth movement and jitter of the elastic filter screen, and further improve the jitter mixing effect of the activated carbon, so that the activated carbon in the first filter tank and the second filter tank are mixed together, and the usage of the activated carbon in the first filter tank and the second filter tank can be made roughly the same, so as to extend the service life of the filter assembly.

[0016] The digital new exhaust fan unit intelligent connection system and control method of the present invention, through the setting of the rotating plate, elastic member, and top plate, the top plate moves back and forth in the radial direction, and the lower end side of the rotating plate is in sliding contact with the upper end side of the top plate, so that the rotating plate swings back and forth, and the elastic member is constantly shaking, so as to facilitate the activated carbon located on both sides to be moved to the middle, which is conducive to shaking and detaching the impurities adsorbed on the activated carbon, and mixing the activated carbon. Then, through the setting of the third and fourth protrusions, the radial back and forth movement of the top plate drives the third protrusions to move back and forth in the radial direction, and the outer side of the third protrusion is in sliding contact with the outer side of the fourth protrusion, so as to expand the range of the back and forth swing of the rotating plate, which is conducive to increasing the amplitude of the shaking of the elastic member, so as to further shake and detach the impurities adsorbed on the activated carbon, and further improve the effect of the mixing of the activated carbon, so that the activated carbon in the first filter tank and the second filter tank are mixed together, which can make the use of the activated carbon in the first filter tank and the second filter tank roughly the same, so as to extend the service life of the filter assembly.

[0017] The digital new exhaust fan unit intelligent connection system and control method of the present invention, through the setting of elastic filter screen and through holes, the elastic filter screen moves back and forth radially and shakes, so that the impurities adsorbed on the activated carbon can be shaken off in time, and the activated carbon is filtered through the elastic filter screen, so that the impurities can enter the fixed cylinder through several through holes, thereby extending the service life of the activated carbon. Then, through the setting of the heater, the heater is started to heat the gas in the fixed cylinder, and the hot gas passes through several through holes, thereby drying the activated carbon in the frame, which is conducive to restoring the activity of the activated carbon and extending the service life of the activated carbon.

[0018] The present invention provides a digital fresh air exhaust unit intelligent connection system and control method thereof, wherein each digital fresh air exhaust unit is equipped with an intelligent air valve, which can accurately adjust the air pressure according to the instructions issued by the central controller to adapt to the ever-changing indoor environmental requirements. Based on the real-time collected data such as CO2, VOC, PM2.5, temperature, humidity, and wind pressure, the central controller dynamically adjusts the air valve opening of each digital fresh air exhaust unit through the intelligent connection algorithm in the intelligent connection system, optimizes the ratio of fresh air introduction and exhaust air discharge, thereby effectively improving the indoor air quality and achieving efficient energy utilization. The intelligent connection system also provides a user interface, allows manual adjustment of settings, supports remote monitoring and maintenance, and ensures efficient operation and convenient maintenance of the system.

For example, when there are many people or the indoor air quality is poor, the intelligent connection system will automatically increase the air supply volume to improve the indoor environment.

[0037] Specific use of the present invention: The intelligent connection system includes several new digital exhaust units, central controllers, Internet of Things (IoT) technology, centralized control cabinets, and servers.

[0038] The central controller is equipped with a LCD touch screen, which is installed in the corresponding room to display the unit operation status and related settings, including: unit power on and off, wind control mode selection, temperature setting, fan mode selection, timed power on and off and other functions, display: fan operation gear, air valve opening, ultraviolet sterilization lamp status, energy consumption data, CO2, VOC, PM2.5, temperature, humidity, wind pressure and other sensor data; the central controller connects the detection component 51 to the system through an electrical connection.

[0039] Internet of Things (IoT) technology includes mobile terminals, which have networking capabilities and can download APP. Each new exhaust fan unit has a unique identifier and can automatically adjust the working status of the unit according to user behavior patterns and preferences. The user interface supports voice control function, and users can control the unit through natural language commands. The specific steps are: 1. Download the APP through the application store on the mobile phone; 2. Enter the APP interface to register a user account or developer account; 3. Use the APP to scan the QR code of the central controller of the new exhaust fan unit, select a Wi-Fi with networking function, select the corresponding SSID account and fill in the password. The new exhaust fan unit will automatically connect to the network and upload data with corresponding permissions for users to use.

[0040] The centralized control cabinet collects the status of the new exhaust fan unit and related setting parameters, and converts the RS485 communication protocol into the TCP communication protocol and transmits it to the server. RS stands for "Recommended Standard" in English, and RS485 is a commonly used serial communication bus standard, which is widely used in data transmission and communication in the field of industrial automation.

[0041] The server displays the specific operating parameters and setting parameters of each new exhaust fan unit. Historical data, historical alarms and instrument data are stored in the server. The full-day operating data of each air-conditioning unit is obtained and stored, forming reports and logs for each air-conditioning unit, and providing a visual human-computer interface.

[0042] The core of the intelligent connection system is the digital new exhaust fan units distributed throughout the building. Each digital new exhaust fan unit is equipped with an intelligent air valve that can accurately adjust the wind pressure according to the instructions issued by the central controller to adapt to the ever-changing indoor environment needs. Based on the real-time collected data such as CO2, VOC, PM2.5, temperature, humidity, wind pressure, etc., the central controller dynamically adjusts the air valve opening of each digital new exhaust fan unit through the intelligent connection algorithm in the intelligent connection system to optimize the ratio of fresh air introduction and exhaust air discharge, thereby effectively improving indoor air quality and achieving efficient energy utilization. The intelligent connection system also provides a user interface that allows manual adjustment of settings and supports remote monitoring and maintenance to ensure efficient operation and convenient maintenance of the system.

[0043] The staff distributed several new digital exhaust fan units throughout the building. All of these new digital exhaust fan units can receive signals from the central controller and be intelligently controlled through the central controller and the Internet of Things.

[0044] When the digital fresh air exhaust unit supplies air to the room, the central controller controls the intelligent fresh air valve 14 and the intelligent air supply valve 16 to open, and the intelligent return air valve 18 and the intelligent exhaust valve 20 to close. The central controller controls the first EC fan 28 to start and suck the outdoor gas into the first air intake chamber 23 through the first air intake frame 12 and the intelligent fresh air valve 14. The gas in the first air intake chamber 23 enters the first filter tanks 37 and the second filter tanks 38 through the first air intake hole 39 and the second air intake hole 40, so that the gas is multi-filtered by the activated carbon in the first filter tanks 37 and the second filter tanks 38. The fully filtered gas enters the first exhaust chamber 25 through the second air outlet 42 and the first air outlet 41. The central controller controls the ultraviolet sterilization lamp 50 to start and sterilize the gas in the first exhaust chamber 25, and the detection component 51 detects the quality of the gas in the first exhaust chamber 25. Finally, the gas in the first exhaust chamber 25 enters the room through the first air outlet frame 15 and the intelligent air supply valve 16.

[0045] When the digital fresh air exhaust unit discharges the indoor gas, the central controller controls the intelligent return air valve 18 and the intelligent exhaust air valve 20 to open, and the intelligent fresh air valve 14 and the intelligent air supply valve 16 to close. The central controller controls the second EC fan 29 to start and suck the indoor gas into the second air intake chamber 24 through the second air intake frame 17 and the intelligent return air valve 18. The gas in the second air intake chamber 24 enters the first filter tanks 37 and the second filter tanks 38 through the first air intake hole 39 and the second air intake hole 40, so that the gas is multi-filtered by the activated carbon in the first filter tanks 37 and the second filter tanks 38. The fully filtered gas enters the second exhaust chamber 26 through the second air outlet hole 42 and the first air outlet hole 41. The central controller controls the ultraviolet sterilization lamp 50 to start and sterilize the gas in the second exhaust chamber 26, and the detection component 51 detects the quality of the gas in the second exhaust chamber 26. Finally, the gas in the second exhaust chamber 26 is discharged to the outside through the second air outlet frame 19 and the intelligent exhaust valve 20.

[0046] The central controller controls the stepper motor 30 to start, and the stepper motor 30 starts to drive the rotating shaft 33 to rotate, and the rotating shaft 33 rotates to drive the rotating cylinder 32 to rotate, and the rotating cylinder 32 rotates to drive the four baffles 34 to rotate, so that the four filter chambers 35 move to the lower side of the interior of the fixed cylinder 31 in sequence. At this time, the filter chamber 35 that has just filtered the gas moves to the lower side of the interior of the fixed cylinder 31, and the first discharge valves 48 and the second discharge valves 49 are opened, so that the activated carbon in the first filter tanks 37 and the second filter tanks 38 fall into the frame 47. The rotating shaft 33 continues to rotate, driving the rotating cylinder 32 and the frame 47 to rotate. The rotation of the frame 47 drives the two push rods 53 to rotate around the rotating shaft 33. One end of the two push rods 53 is in sliding contact with the outer side of the guide block 55, so that the push rods 53 move radially inward under the guiding action of the outer side of the guide block 55. The movement of the push rods 53 drives the movable plate 52 to move radially inward; and the radial inward movement of the movable plate 52 stretches the spring 63 to generate elastic force. After one end of the push rod 53 is out of contact with the outer side of the guide block 55, the push rod 53 is moved radially inward under the action of the elastic force of the spring 63. 53 and the movable plate 52 move radially inwardly, so that under the guiding action of the guide block 55 and the elastic force of the spring 63, the two push rods 53 and the movable plate 52 move radially back and forth, and the radial back and forth movement of the two movable plates 52 drives the elastic filter screen 54 to move back and forth, so as to shake and mix the activated carbon; and the positions at which one end of the two push rods 53 contacts the outer side of the guide block 55 are different, so that the positions at which the two push rods 53 drive the movable plate 52 to move are different, so that the back and forth movement of the two sides of the elastic filter screen 54 is different, thereby improving the shaking and mixing effect of the activated carbon.

[0047] Next, one end of the push rod 53 slides with the outer side of the first protrusion 56, so that under the guidance of the first protrusion 56, the push rod 53 and the movable plate 52 are pushed to move radially inward; and one end of the push rod 53 slides with the outer side of the second protrusion 57, so that under the guidance of the second protrusion 57, the push rod 53 and the movable plate 52 are pushed to move radially inward; because the outer diameter of the first protrusion 56 is larger than the outer diameter of the second protrusion 57, the push rod 53 and the movable plate 52 move radially inward to different degrees, so that the two push rods 53 and the movable plate 52 can further move back and forth in the radial direction, improve the radial back and forth movement and shaking of the elastic filter 54, and further improve the shaking and mixing effect of the activated carbon. At the same time, the elastic filter 54 moves back and forth in the radial direction and shakes, so that the impurities adsorbed on the activated carbon can be shaken off in time, and the activated carbon is filtered by the elastic filter 54, so that the impurities can enter the fixed cylinder 31 through the several through holes 64, thereby extending the service life of the activated carbon. The central controller controls the heater 65 to start, and the heater 65 starts to heat the gas in the fixed cylinder 31. The hot gas passes through the plurality of through holes 64, thereby drying the activated carbon in the frame 47, which is beneficial to restore the activity of the activated carbon and extend the service life of the activated carbon.

[0048] Then, the movable plate 52 and the push rod 53 move radially inward to drive the top plate 59 to move, and the top plate 59 moves to push the rotating plate 58 to swing through the sliding contact between the lower end side of the rotating plate 58 and the upper end side of the top plate 59. The swing of the rotating plate 58 drives the elastic member 60 to move; and the movable plate 52 moves radially outward to pull the elastic member 60 to move, so that the rotating plate 58 swings back and forth, so that the movable plate 52 and the top plate 59 move back and forth in the radial direction, and the lower end side of the rotating plate 58 slides with the upper end side of the top plate 59. The inclined surface of the sliding contact makes the rotating plate 58 swing back and forth, and the elastic member 60 keeps shaking, so as to move the activated carbon on both sides to the middle, which is beneficial to shake off the impurities adsorbed on the activated carbon and mix the activated carbon.

[0049] At the same time, the radial back-and-forth movement of the top plate 59 drives the third protrusions 61 to move radially back and forth, and the outer sides of the third protrusions 61 are in sliding contact with the outer sides of the fourth protrusions 62, thereby expanding the range of the back-and-forth swinging of the rotating plate 58, which is beneficial to increasing the vibration amplitude of the elastic member 60, so as to further shake off the impurities adsorbed on the activated carbon and further improve the mixing effect of the activated carbon.

[0050] Finally, the rotating cylinder 32 rotates to drive the frame 47 to move to the upper side of the interior of the fixed cylinder 31, and the central controller controls the first feed valves 44 and the second feed valves 45 to open, thereby redistributing the fully mixed activated carbon in the frame 47 to the first filter tanks 37 and the second filter tanks 38, so that the usage of the activated carbon in the first filter tanks 37 and the second filter tanks 38 is roughly the same, so as to extend the service life of the filter assembly.

[0051] When the digital fresh air exhaust unit is supplying and exhausting air at the same time, the central controller controls the intelligent fresh air valve 14 and the intelligent supply air valve 16 to open, and the intelligent return air valve 18 and the intelligent exhaust air valve 20 to open. The central controller controls the first EC fan 28 and the second EC fan 29 to start, and the outdoor air is sucked into the first air intake cavity 23 through the first air intake frame 12 and the intelligent fresh air valve 14, and the indoor air is sucked into the second air intake cavity 24 through the second air intake frame 17 and the intelligent return air valve 18.

[0052] Secondly, the gas in the first air inlet chamber 23 enters the first filter tanks 37 and the second filter tanks 38 through the first air inlet holes 39 and the second air inlet holes 40 on one side, and the gas in the second air inlet chamber 24 enters the first filter tanks 37 and the second filter tanks 38 through the first air inlet holes 39 and the second air inlet holes 40 on the other side. Thus, the activated carbon in the first filter tanks 37 and the second filter tanks 38 performs multiple filtering actions on the gas on one side of the filter assembly; the central controller controls the stepper motor 30 to start and drive the rotating cylinder 32 to rotate, so that the first filter tanks 37 and the second filter tanks 38 move to the lower side of the fixed cylinder 31, and the central controller controls the first discharge valves 48 or the second discharge valves 49 to open, so that the activated carbon in the first filter tanks 37 or the second filter tanks 38 falls into the frame 47 for mixing, and the activated carbon in the first filter tanks 37 or the second filter tanks 38 is left to filter the gas in the second air inlet chamber 24, so that multiple filtering actions can be performed on indoor or outdoor gas at the same time. The central controller controls the stepper motor 30 to start and drive the rotating cylinder 32 to rotate, so that the first filter tanks 37 and the second filter tanks 38 move to the upper side of the fixed cylinder 31, and the central controller controls the first feed valves 44 or the second feed valves 45 to open, so that the activated carbon in the frame 47 is redistributed to the first filter tanks 37 or the second filter tanks 38, which can extend the service life of the filter assembly. Among them, when one part of the filter assembly is damaged, only the activated carbon in the corresponding filter chamber 35 needs to be replaced, and it does not affect the multiple filtering effects of the activated carbon in the gas filter chamber 35 on indoor or outdoor gases, which greatly reduces the cost of use.

[0053] Next, the gas on one side of the filter assembly enters the first exhaust chamber 25 through the second air outlet 42 and the first air outlet 41 on one side, and the central controller controls the ultraviolet sterilization lamp 50 to start sterilizing the gas in the first exhaust chamber 25, and the detection component 51 detects the quality of the gas in the first exhaust chamber 25. The gas on the other side of the filter assembly enters the second exhaust chamber 26 through the second air outlet 42 and the first air outlet 41 on the other side, and the central controller controls the ultraviolet sterilization lamp 50 to start sterilizing the gas in the second exhaust chamber 26, and the detection component 51 detects the quality of the gas in the second exhaust chamber 26.

[0054] Finally, the gas in the first exhaust cavity 25 enters the room through the first air outlet frame 15 and the intelligent air supply valve 16; the gas in the second exhaust cavity 26 is discharged to the outside through the second air outlet frame 19 and the intelligent exhaust valve 20.

[0055] A digital new exhaust fan unit intelligent connection system and a control method thereof of the present invention, through the arrangement of a guide block 55, a push rod 53, a movable plate 52, and a spring 63, enables the two push rods 53 and the movable plate 52 to move radially back and forth under the guiding action of the guide block 55 and the elastic force of the spring 63, and the radial back and forth movement of the two movable plates 52 drives the elastic filter 54 to move back and forth, so as to facilitate shaking and mixing of the activated carbon; and the positions at which one end of the two push rods 53 contacts the outer side of the guide block 55 are different, so that the positions at which the two push rods 53 drive the movable plate 52 to move are different, so that the back and forth movement of the two sides of the elastic filter 54 is different, thereby improving the effect of shaking and mixing the activated carbon. Through the arrangement of the first protrusion 56 and the second protrusion 57, one end of the push rod 53 slides in contact with the outer side of the first protrusion 56, so that under the guidance of the first protrusion 56, the push rod 53 and the movable plate 52 are pushed to move radially inward; and one end of the push rod 53 slides in contact with the outer side of the second protrusion 57, so that under the guidance of the second protrusion 57, the push rod 53 and the movable plate 52 are pushed to move radially inward; because the outer diameter of the first protrusion 56 is greater than the outer diameter of the second protrusion 57, the degree of radial inward movement of the push rod 53 and the movable plate 52 is different, so that the two push rods 53 and the movable plate 52 can further move back and forth radially, improve the radial back and forth movement and jitter of the elastic filter screen 54, and further improve the jitter mixing effect of the activated carbon, so that the activated carbon in the first filter tanks 37 and the second filter tanks 38 are mixed together, and the usage of the activated carbon in the first filter tanks 37 and the second filter tanks 38 can be roughly the same, so as to extend the service life of the filter assembly.

[0056] A digital new exhaust fan intelligent connection system and control method of the present invention, through the arrangement of a rotating plate 58, an elastic member 60, and a top plate 59, the top plate 59 moves radially back and forth to cooperate with the lower end side of the rotating plate 58 to slide in contact with the inclined surface of the upper end side of the top plate 59, so that the rotating plate 58 swings back and forth, and the elastic member 60 shakes continuously, so as to facilitate the activation of carbon on both sides to be pushed to the middle, which is beneficial to shake off the impurities adsorbed on the activated carbon and mix the activated carbon. Through the arrangement of the third protrusion 61 and the fourth protrusion 62, the radial back-and-forth movement of the top plate 59 drives the third protrusions 61 to move radially back-and-forth, and the outer side of the third protrusion 61 slides in contact with the outer side of the fourth protrusion 62, thereby expanding the range of the swinging back and forth of the rotating plate 58, which is beneficial to increase the vibration amplitude of the elastic member 60, so as to further shake off the impurities adsorbed on the activated carbon and further improve the mixing effect of the activated carbon, so that the activated carbon in the first filter tank 37 and the second filter tank 38 are mixed together, which can make the usage of the activated carbon in the first filter tank 37 and the second filter tank 38 roughly the same, so as to extend the service life of the filter assembly.

[0057] The digital new exhaust fan unit intelligent connection system and control method of the present invention, through the setting of the elastic filter 54 and the through hole 64, the elastic filter 54 moves back and forth radially and shakes, so that the impurities adsorbed on the activated carbon can be shaken off in time, and the activated carbon is filtered through the elastic filter 54, so that the impurities enter the fixed cylinder 31 through the through holes 64, thereby extending the service life of the activated carbon. Then, through the setting of the heater 65, the heater 65 is started to heat the gas in the fixed cylinder 31, and the hot gas passes through the through holes 64, thereby drying the activated carbon in the frame 47, which is conducive to restoring the activity of the activated carbon and extending the service life of the activated carbon.

[0058] The present invention provides a digital fresh air exhaust unit intelligent connection system and control method thereof, wherein each digital fresh air exhaust unit is equipped with an intelligent air valve, which can accurately adjust the air pressure according to the instructions issued by the central controller to adapt to the ever-changing indoor environmental requirements. Based on the real-time collected data such as CO2, VOC, PM2.5, temperature, humidity, and wind pressure, the central controller dynamically adjusts the air valve opening of each digital fresh air exhaust unit through the intelligent connection algorithm in the intelligent connection system, optimizes the ratio of fresh air introduction and exhaust air discharge, thereby effectively improving the indoor air quality and achieving efficient energy utilization.
