DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1-Figure 6The invention shows an intelligent ventilation system for green buildings, including a drying air supply mechanism, an exhaust mechanism, and a duct vent mechanism. The drying air supply mechanism is used to supply outdoor air into the room, the exhaust mechanism is used to exhaust indoor air to the outside, and the duct vent mechanism is used to assist the drying air supply mechanism and the exhaust mechanism in transporting air to achieve ventilation. The drying air supply mechanism includes an air supply box 101, in which an air supply fan 102 is fixedly installed, and the left and right ends of the air supply box 101 are respectively connected with a connecting pipe 105 and an air inlet pipe 103, and the top of the air supply box 101 is connected with an air delivery pipe 104, and the air delivery pipe 104 is located on the side of the air supply fan 102 away from the air inlet pipe 103, and a filter screen 118 is fixedly installed in the air supply box 101, and the filter screen 118 is located between the air delivery pipe 104 and the air supply fan 102, and the end of the connecting pipe 105 away from the air supply box 101 is connected with a sealed drying cylinder 106. The sealed drying cylinder 106 is provided with a storage net cylinder 110, which is a porous mesh structure and filled with a desiccant 111. The end of the connecting pipe 105 connected to the sealed drying cylinder 106 is fixedly connected to the storage net cylinder 110. The top of the sealed drying cylinder 106 is connected to an air guide pipe 113. The storage net cylinder 110 and the air guide pipe 113 are both located on the side of the piston plate 107 close to the connecting pipe 105, and the air supply The first solenoid valve 114, the second solenoid valve 115 and the third solenoid valve 116 are respectively arranged on the pipe 104, the connecting pipe 105 and the air guide pipe 113. The end of the air guide pipe 113 away from the sealed drying cylinder 106 is connected to the air supply pipe 104 and is located on the side of the first solenoid valve 114 away from the air supply box 101. An external humidity sensor is fixedly installed in the air inlet pipe 103, and an internal humidity sensor 112 is fixedly installed in the sealed drying cylinder 106. The drying air supply mechanism also includes a drying control system, which includes a drying control module and a humidity analysis module. The humidity analysis module has a preset humidity threshold. The internal humidity sensor 112 and the external humidity sensor are both connected to the humidity analysis module by signal, and the humidity analysis module is connected to the drying control module by signal. The drying control module is connected to the air supply fan 102, the internal humidity sensor 112, the first solenoid valve 114, the second solenoid valve 115, and the third solenoid valve 116 by signal.

[0021] The exhaust mechanism includes an exhaust box 201, in which an exhaust fan 202 is fixedly installed, and the drying control module is connected to the exhaust fan 202 by signal. The left and right ends of the exhaust box 201 are respectively connected with an air outlet pipe 203 and a continuous exhaust pipe 204, and the duct air outlet mechanism includes an air supply duct, an air supply outlet, an exhaust duct, and an exhaust outlet. The two ends of the air supply duct are respectively connected with the air supply pipe 104 and the air supply outlet, and the two ends of the exhaust duct are respectively connected with the air outlet pipe 203 and the exhaust outlet. The air supply duct, the air supply outlet, the exhaust duct, and the exhaust outlet can be arranged as needed according to the situation, and the arrangement of the air supply duct, etc. is a well-known technology for those skilled in the art and will not be elaborated here.

[0022] Under normal circumstances (i.e. when the outdoor air humidity is less than the humidity threshold), the first solenoid valve 114 is in the open state, and the second solenoid valve 115 and the third solenoid valve 116 are in the closed state. When ventilation is performed, the air supply fan 102 is started. Under the action of the air supply fan 102, outdoor air is drawn into the air supply box 101 through the air inlet pipe 103 (when the air passes through the filter 118, the filter 118 will filter the dust in the air to improve the ventilation quality and effect), and then is sent into the room through the air supply pipe 104, the air supply duct, and the air supply port. At the same time, the exhaust fan 202 is started, and the air can be exhausted through the exhaust port, the exhaust duct, the air outlet pipe 203, the exhaust pipe 204, the exhaust pipe 205, the exhaust pipe 206, the exhaust pipe 207, the exhaust pipe 208, the exhaust pipe 209, the exhaust pipe 210, the exhaust pipe 211, the exhaust pipe 212, the exhaust pipe 213, the exhaust pipe 214, the exhaust pipe 215, the exhaust pipe 216, the exhaust pipe 217, the exhaust pipe 218, the exhaust pipe 219, the exhaust pipe 220, the exhaust pipe 221, the exhaust pipe 224, the exhaust pipe 225, the exhaust pipe 226, the exhaust pipe 227, the exhaust pipe 228, the exhaust pipe 229, the exhaust pipe 229, the exhaust pipe 229, the exhaust pipe 221, the exhaust pipe 229, the exhaust pipe 221, the exhaust pipe 22 204 discharges indoor air to the outside to achieve ventilation. During the ventilation process, the external humidity sensor is used to monitor the outdoor air humidity in real time, and the humidity data monitored by the external humidity sensor is transmitted to the humidity analysis module in real time. When the humidity data monitored by the external humidity sensor exceeds the humidity threshold, the humidity analysis module sends a drying signal to the drying control module, so that the drying control module closes the first solenoid valve 114, opens the second solenoid valve 115 and the third solenoid valve 116, and starts the internal humidity sensor 112. After the first solenoid valve 114 is closed, the second solenoid valve 115 and the third solenoid valve 116 are opened, the air supply fan 102 is turned on. The outdoor air drawn in will be transported to the sealed drying cylinder 106 through the connecting pipe 105, and the outdoor air will first enter the agent storage net cylinder 110 and contact the desiccant 111 and then be discharged to the outside of the agent storage net cylinder 110, so that the agent storage net cylinder 110 can dry the outdoor air. After the air is dried, it will enter the room through the air guide pipe 113, the air supply pipe 104, the air supply pipe, and the air supply port in sequence, thereby effectively preventing the indoor humidity from being too high (after the outdoor humidity drops below the humidity threshold, the humidity analysis module will send a signal to stop drying to the drying control module, causing the drying control module to close the second solenoid valve 115 and the third solenoid valve 116 and open the first solenoid valve 114 to restore the normal ventilation mode). After the internal humidity sensor 112 is opened, the air humidity in the sealed drying cylinder 106 will be monitored in real time, and the monitored humidity data will be sent to the humidity analysis module in real time. When the humidity data monitored by the internal humidity sensor 112 also exceeds the humidity threshold, the humidity analysis module will send a ventilation stop signal to the drying control module, so that the drying control module turns off the air supply fan 102 and the exhaust fan 202 to stop ventilation. At the same time, the drying control module will also turn off the internal humidity sensor 112, the second solenoid valve 115, the third solenoid valve 116 and open the first solenoid valve 114. Therefore, through the setting of the drying air supply mechanism, when the outdoor air humidity is high, the drying air supply mechanism will perform intelligent and automatic adjustment. After the adjustment, the outdoor air will be dried first, and then the dry air will be sent into the room. This can effectively prevent the indoor humidity from increasing significantly due to ventilation when the outdoor air humidity is high, thereby causing the residents to feel uncomfortable and other problems. It greatly improves the intelligence, practicality and comfort of the ventilation system.

[0023] The drying control system also includes a priority setting module, which is connected to the drying control module by signal. The drying control system also includes a ringing reminder module, which is connected to the ringing reminder module by signal.

[0024] The priority setting module is used to set the priority of ventilation, and the priorities are divided into high and low. When the priority of ventilation is set to low, when the humidity data monitored by the internal humidity sensor 112 exceeds the humidity threshold, the humidity analysis module will send a signal to the drying control module to stop ventilation. On the contrary, when the priority of ventilation is set to high, when the humidity data monitored by the internal humidity sensor 112 exceeds the humidity threshold, the humidity analysis module will not send a signal to the drying control module to stop ventilation, so as to continue ventilation, and the humidity analysis module will send a reminder instruction to the drying control module, causing the drying control module to start the ringing reminder module to send a reminder ring to remind relevant personnel that the humidity of the air currently delivered to the room is high, so that when the drying effect cannot meet the drying requirements, the drying air supply mechanism will choose to continue ventilation or automatically stop ventilation according to the ventilation priority set by the occupants, further improving the intelligence of the ventilation system and enriching the diversity of the ventilation system functions.

[0025] The sealed drying cylinder 106 is provided with a piston plate 107 which is slidably and sealedly connected thereto. A sealed cylinder 108 is embedded through the outer wall of the sealed drying cylinder 106 near the air supply box 101. A cylinder 109 is fixedly installed in the sealed cylinder 108. The output end of the cylinder 109 is fixedly connected to the piston plate 107. Once the drying control module receives the intermediate drying signal from the drying control module, after the ventilation system is turned off, the drying control module will control the electric heater 117 to dry the desiccant 111. During the drying process, the drying control module will control the first solenoid valve 114, the second solenoid valve 115, and the third solenoid valve 116 to be in a closed state, and then start the electric heater 117 to heat the inside of the sealed drying cylinder 106 (the heating temperature and heating time are preset in the drying control module) to dry the moisture in the desiccant 111 and restore the desiccant 111 to a dry state, which is beneficial to the subsequent drying of the air. After the heating and drying is completed, the drying control module will turn off the electric heater 117.

[0026] The end of the sealed nano-cylinder 108 connected to the sealed drying cylinder 106 is set to an open shape, the electric heater 117 is located on the side of the piston plate 107 close to the connecting pipe 105, the drying control module is connected to the cylinder 109 signal, and the outer wall of the sealed drying cylinder 106 away from the connecting pipe 105 is provided with a vent hole 119. The drying process also includes the following operations: after the drying control module starts the electric heater 117, it will also control the cylinder 109 to push the piston plate 107 to move a preset length away from the connecting pipe 105, which can play a pressure relief role to prevent the electric heater 117 from heating the inside of the sealed drying cylinder 106. The air pressure in the area of ​​the piston plate 107 close to the connecting pipe 105 is too high, thereby improving safety. After the heating and drying is completed, the drying control module will turn on the second electric The magnetic valve 115 controls the cylinder 109 to repeatedly push and pull the piston plate 107 for a preset number of times, and there will be a preset time interval between each push and pull of the piston plate 107 by the cylinder 109. In this way, on the one hand, the hot air in the sealed drying cylinder 106 can be discharged to the outside. On the other hand, when the cylinder 109 pulls the piston plate 107 to discharge the hot air to the outside, the airflow generated will flush the filter 118 to automatically clean the dust attached to the filter 118, and because there will be a certain time interval between each push and pull, the dust that has been cleaned can be prevented from immediately re-attaching to the filter 118 to a large extent, thereby ensuring the cleaning effect. Finally, the drying control module controls the cylinder 109 to pull the piston plate 107 to reset, and the drying process is now completed. Therefore, through the joint arrangement of the piston plate 107, the cylinder 109, the electric heater 117, etc., the automatic desiccant 111 can be dried so that the desiccant 111 is restored to a dry state. In the process of drying the desiccant 111, the filter 118 will also be automatically cleaned, further improving the intelligence and practicality of the ventilation system.

[0027] In addition, when the ventilation priority is set to a low level, when the drying control module receives a signal to stop drying from the humidity analysis module, the drying control module will also control the electric heater 117 to dry the desiccant 111, and after the drying process is completed, if the occupant does not actively turn off the ventilation system, the drying control module will control the second solenoid valve 115 and the third solenoid valve 116 to be in an open state, the first solenoid valve 114 to be in a closed state, and start the supply fan 102 and the exhaust fan 202 to continue ventilation.

[0028] The second implementation method: Figure 7-Figure 9A smart ventilation system for a green building is shown. Different from the first embodiment, the drying air supply mechanism also includes a drying aid component, which includes a sealed air cylinder 401. An admittance tube 402 is connected between the sealed air cylinder 401 and the connecting pipe 105. A spring 404 is fixedly installed in the sealed air cylinder 401. One end of the spring 404 close to the admittance tube 402 is fixedly connected to a sliding sealing plate 405 that is slidingly sealed with the sealed air cylinder 401. A fourth solenoid valve 403 is provided on the admittance tube 402. The drying control module is connected to the fourth solenoid valve 403 by signal. The admittance tube 402 is located on the side of the second solenoid valve 115 away from the air supply box 101.

[0029] In the present embodiment, during the drying process of the desiccant 111, after the drying control module controls the cylinder 109 to push the piston plate 107 to move a preset length in the direction away from the connecting pipe 105, before the heating and drying is completed, the drying control module will open the fourth solenoid valve 403 and control the cylinder 109 to repeatedly push and pull the piston plate 107 for a preset number of times (the purpose of repeatedly pushing and pulling the piston plate 107 here is different from the purpose of repeatedly pushing and pulling the piston plate 107 after the heating and drying is completed. After the heating and drying is completed, the drying control module will still control the cylinder 109 to repeatedly push and pull the piston plate 107 to exhaust hot air and automatically clean the filter 118). During the process of the cylinder 109 repeatedly pushing and pulling the piston plate 107, the hot air will repeatedly enter and exit the sealed air receiving cylinder 401 through the connecting pipe 105 and the admittance tube 402, thereby effectively promoting the contact between the hot air and the desiccant 111, thereby effectively improving the effect and efficiency of the drying process.

[0030] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
