A connecting hose is fixed at the bottom of the drainage groove and penetrates through the ventilation duct to communicate with the dust discharge pipe.

[0009] Further, the driving drying structure includes a transmission frame fixed inside the ventilation duct and a servo motor fixed outside the ventilation duct. A rotating shaft inside the transmission frame is rotatably connected to a second installation frame.

A water absorption core is fixedly connected inside the second installation frame. Two elastic cleaning structures are fixedly connected to the upper and lower edges of the opposite sides of the second installation frame. The second installation frame can be flipped to make the two elastic cleaning structures contact the dust-proof net structure.

[0010] Further, the elastic cleaning structure includes installation seats and connecting rollers respectively fixed to the opposite side edges of the second installation frame. Connecting shafts are fixedly installed at both ends of the connecting roller. The connecting roller is rotatably installed between the two installation seats through the connecting shafts.

Detailed Description of the Invention

[0029] Example 1, consisting of Figure 1-3Provided is an intelligent building ventilation device, including a ventilation duct 1 inserted into the ventilation channel of an intelligent building. Installation flanges 11 are fixedly installed at the front and rear of the ventilation duct 1. The two installation flanges 11 fixedly connect the ventilation duct 1 to the ventilation channel of the intelligent building through installation bolts. A dust-proof net structure 4 is installed at the left edge of the inner part of the ventilation duct 1. A dust discharge groove 12 is opened at the bottom of the ventilation duct 1 near the dust-proof net structure 4. A dust discharge pipe 8 is fixedly communicated with the bottom of the dust discharge groove 12 at the bottom of the ventilation duct 1. A driving and drying structure 5 is installed inside the ventilation duct 1 near the dust-proof net structure 4. A heating module 6 is fixed in the middle of the ventilation duct 1. A fan device 7 is fixedly installed near the heating module 6. A mosaic frame 13 is fixedly installed on the right part of the ventilation duct 1. A convex groove is penetrated through the mosaic frame 13, and a detachable air filtration device 3 is embedded in the convex groove. A sensor detection module 2 is penetrated through the top of the ventilation duct 1 near the detachable air filtration device 3. The sensor detection module 2, the driving and drying structure 5, the heating module 6 and the fan device 7 are electrically controlled and connected to an external intelligent building console.

[0030] Specifically, first, the ventilation duct 1 is fixed in the ventilation channel of the intelligent building through the installation flanges 11 and installation bolts. The inside of the ventilation duct 1 includes a sensor detection module 2, a detachable air filtration device 3, a dust-proof net structure 4, a driving and drying structure 5, a heating module 6 and a fan device 7. When ventilation is required, the device works by controlling through the console of the intelligent building. When the fan device 7 is started, air enters from the left end of the ventilation duct 1. First, most of the dust and impurities are blocked by the dust-proof net structure 4. The simply filtered air passes through the driving and drying structure 5 to absorb the moisture in the air and keep the inside of the ventilation duct 1 dry. The air that has undergone dust-proof and drying treatment continues to flow to the right and passes through the detachable air filtration device 3 to filter out the fine particles and harmful gases in the air. Thus, the clean air enters the intelligent building. During the ventilation process, the air entering the intelligent building is monitored in real time through the sensor detection module. The sensor detection module 2 monitors the wind speed, temperature and humidity, particle concentration and gas concentration of the incoming air in real time and transmits the data to the external intelligent building console. The console adjusts the rotation speed of the fan device 7 according to the data and reminds the user of the air quality to achieve intelligent ventilation.

[0031] Among them, a collection box can be placed in the lower part of the dust discharge pipe 8 in the ventilation duct of the intelligent building to collect the fallen dust.

[0032] In this embodiment, by Figure 4-5Given that, the dust-proof net structure 4 includes a dust-proof frame 46. Four sides of the outer end of the dust-proof frame 46 are fixed with a plurality of springs 42 which are fixedly connected to the inner wall of the ventilation duct 1. And four edges of the outer end of the dust-proof frame 46 are fixed with rubber sleeves 41 which are connected and sealed with the inside of the ventilation duct 1. A dust-proof net 43 is fixed in the middle of the dust-proof frame 46. A drain groove 44 is formed at the inner bottom edge of the dust-proof frame 46 near the position of the driving and drying structure 5. The bottom of the drain groove 44 is fixed with a connecting hose 45 which penetrates through the ventilation duct 1 and is communicated with the dust exhaust duct 8.

[0033] Specifically, the dust-proof net structure 4 is tightly connected to the inner wall of the ventilation duct 1 through the springs 42 and the rubber sleeves 41 to ensure the sealing performance. Air enters from the left end of the ventilation duct 1. First, it passes through the dust-proof net structure 4. The dust-proof net 43 blocks most of the dust and impurities, simply filtering the air.

[0034] When the elastic cleaning structure 55 comes into contact, it will squeeze the dust-proof net 43. And the dust-proof frame 46 is connected to the ventilation duct 1 through the springs 42 and the rubber sleeves 41. When it receives the extrusion, it will displace and stretch the plurality of springs 42. When the hard bristles 553 are separated from the dust-proof net 43, the plurality of springs 42 drive the dust-proof frame 46 to return to its original position, thereby driving the dust-proof net to shake, so as to shake off some of the adsorbed dust to achieve cleaning.

[0035] In this embodiment, Figure 7 Given that, the driving and drying structure 5 includes a transmission frame 51 fixed inside the ventilation duct 1 and a servo 52 fixed outside the ventilation duct 1. A rotating shaft inside the transmission frame 51 is rotatably connected to the second mounting frame 53. The output shaft of the servo 52 penetrates through the ventilation duct 1 and the transmission frame 51 and is in transmission connection with the rotating shaft. A water absorption core 54 is fixedly connected inside the second mounting frame 53. Two elastic cleaning structures 55 are fixed on the upper and lower edges of the opposite sides of the second mounting frame 53. The second mounting frame 53 can be flipped to make the two elastic cleaning structures 55 contact with the dust-proof net structure 4.

[0036] Specifically, the simply filtered air passes through the driving and drying structure 5. The silica gel particles in the water absorption core 54 absorb the moisture in the air to keep the inside of the ventilation duct 1 dry. When there is no need to dry the incoming air, an instruction is sent to the servo through the console. The servo 52 drives the rotating shaft inside the transmission frame 51 to rotate, so that the second mounting frame 53 is flipped counterclockwise by ninety degrees. Thus, a small amount of the moist air is absorbed by the water absorption core 54, and the moist air normally enters the intelligent building interior.

[0037] Among them, the water absorption core 54 includes isolation nets fixed on both sides inside the second mounting frame 53. Silica gel particles are filled between the two isolation nets; the silica gel particles in the water absorption core 54 absorb the moisture in the air to keep the air inside the ventilation duct 1 dry.

[0038] In this embodiment, Figure 6Given that the detachable air filtering device 3 includes a first mounting frame 31. A rubber ring is sleeved outside the first mounting frame 31 and is embedded into the inlay frame 13 through the rubber ring for sealing. Two handles 33 are fixed on both side edges of the first mounting frame 31, and a filter element 32 is fixed inside the first mounting frame 31. The filter element 32 is composed of a PP layer and an activated carbon layer; the PP layer and the activated carbon layer in the filter element 32 filter out fine particulate matter and harmful gases in the air respectively, so that clean air enters the intelligent building. During later disassembly and replacement, only need to hold the two handles 33 to pull out the detachable air filtering device 3 from the ventilation duct 1 and then install a new one.

[0039] In this embodiment, the sensor detection module 2 includes a temperature and humidity sensor, a particulate matter sensor, a wind speed sensor and a gas sensor; during the ventilation process, the sensor detection module 2 monitors the wind speed, temperature and humidity, particulate matter concentration and gas concentration of the incoming air in real time, and transmits the data to the external intelligent building control console. The console adjusts the rotation speed of the fan device 7 according to the data and reminds the user of the air quality to achieve intelligent ventilation.

[0040] Embodiment 2, on the basis of Embodiment 1, Figure 8 Given that the elastic cleaning structure 55 includes a mounting seat 552 and a connecting roller 551 respectively fixed on opposite side edges of the second mounting frame 53. Connecting shafts are fixed at both ends of the connecting roller 551, and the connecting roller 551 is rotatably installed between the two mounting seats 552 through the connecting shafts. A hard brush 553 is fixed on the top of the connecting roller 551. A torsion spring is sleeved outside the connecting shaft. One end of the torsion spring is fixedly connected with the mounting seat 552, and the other end is fixedly connected with the connecting roller 551.

[0041] Specifically, as the air flows, dust and impurities gradually accumulate on the dust-proof net 43. The console can be set to clean regularly at a set time. The steering gear 52 drives the rotation of the rotating shaft in the transmission frame 51, so that the second mounting frame 53 rotates counterclockwise. When the two elastic cleaning structures 55 are separated from the transmission frame 51 during the rotation of the second mounting frame 53, the two elastic cleaning structures rebound to be vertical and parallel to the second mounting frame 53. When the two elastic cleaning structures 55 rotate and contact the dust-proof net 43, the hard brush 553 on the connecting roller 551 contacts the dust-proof net 43 to clean the dust. Since a torsion spring is sleeved outside the connecting shaft, the connecting roller 551 can maintain a practical pressure when contacting the dust-proof net 43, ensuring that the hard brush 553 can fully brush off the dust on the dust-proof net. The cleaned and fallen dust drops through the dust discharge groove 12 into the dust discharge pipe 8 and is finally collected by the collection box. When the elastic cleaning structure 55 rotates and contacts the transmission frame 51, the hard brush 553 contacts the transmission frame 51 and is stressed, driving the connecting roller 551 to rotate and making its torsion spring rotate and contract, so that the second mounting frame 53 can pass through the transmission frame 51, realizing the cyclic rotation of the second mounting frame 53.

[0042] Embodiment 3. On the basis of Embodiment 1, the heating module 6 includes a fixed outer frame, and a plurality of graphene heating sheets are vertically installed in the fixed outer frame; when the temperature of the air entering from outside is relatively low, an instruction is sent to the heating module 6 through the console. The console is provided with a temperature control module, which can realize that the graphene heating sheets quickly heat up and then keep a constant temperature, transfer the heat to the surrounding air, and the air passing through the heating module 6 is heated and enters the intelligent building to keep the indoor temperature unchanged or increase the temperature.

[0043] Working principle:

[0044] First, the ventilation duct 1 is fixed in the ventilation passage of the intelligent building through the mounting flange 11 and the mounting bolts. The ventilation duct 1 includes a sensor detection module 2, a detachable air filtering device 3, a dust-proof net structure 4, a driving drying structure 5, a heating module 6 and a fan device 7.

[0045] When ventilation is required, the equipment is controlled to work through the console of the intelligent building. When the fan device 7 is started, air enters from the left end of the ventilation duct 1. First, it passes through the dust-proof net structure 4. The dust-proof net 43 blocks most of the dust and impurities. The simply filtered air passes through the driving drying structure 5. The silica gel particles in the water absorption core 54 absorb the moisture in the air to keep the inside of the ventilation duct 1 dry. The air that has undergone dust-proof and drying treatments continues to flow to the right and passes through the detachable air filtering device 3. The PP layer and the activated carbon layer in the filter core 32 filter out the fine particulate matter and harmful gases in the air respectively, so that the clean air enters the intelligent building. During the ventilation process, the air entering the intelligent building is monitored in real time through the sensor detection module. The sensor detection module 2 monitors the wind speed, temperature and humidity, particulate matter concentration and gas concentration of the incoming air in real time, and transmits the data to the external intelligent building console. The console adjusts the rotation speed of the fan device 7 according to the data and reminds the user of the air quality to achieve intelligent ventilation;

[0046] When the temperature of the air entering from outside is relatively low, an instruction is sent to the heating module 6 through the console. The console is provided with a temperature control module, which can realize that the graphene heating sheets quickly heat up and then keep a constant temperature, transfer the heat to the surrounding air, and the air passing through the heating module 6 is heated and enters the intelligent building to keep the indoor temperature unchanged or increase the temperature;

[0047] When there is no need to dry the incoming air, an instruction is sent to the servo through the console. The servo 52 drives the rotation of the rotating shaft in the transmission frame 51, so that the mounting frame two 53 rotates counterclockwise by ninety degrees, so that a small amount of the moist air is absorbed by the water absorption core 54, and the moist air normally enters the intelligent building;

[0048] As the air flows, dust and impurities gradually accumulate on the dust-proof net 43. The cleaning time can be set through the console for regular cleaning. The steering gear 52 drives the rotation of the rotating shaft in the transmission frame 51, causing the second mounting frame 53 to flip counterclockwise. When the two elastic cleaning structures 55 are separated from the transmission frame 51 during the flipping process of the second mounting frame 53, the two elastic cleaning structures rebound to maintain a vertical position parallel to the second mounting frame 53. When the two elastic cleaning structures 55 come into contact with the dust-proof net 43 during the flipping, the hard bristles 553 on the connecting roller 551 come into contact with the dust-proof net 43 to clean the dust. Since a torsion spring is sleeved outside the connecting shaft, the connecting roller 551 can maintain a practical pressure when contacting the dust-proof net 43, ensuring that the hard bristles 553 can fully brush off the dust on the dust-proof net. The cleaned and fallen dust drops through the dust discharge groove 12 into the dust discharge pipe 8 and is finally collected by the collection box. When the elastic cleaning structure 55 flips and contacts the transmission frame 51, the hard brush 553 is stressed when contacting the transmission frame 51, driving the connecting roller 551 to rotate and causing its torsion spring to rotate and contract. Thus, the second mounting frame 53 can pass through the transmission frame 51, realizing the cyclic flipping of the second mounting frame 53;

[0049] When the hard bristles 443 contact the dust-proof net 43, they will squeeze the dust-proof net 43. The dust-proof frame 46 is connected to the ventilation duct 1 through springs 42 and rubber sleeves 41. When being squeezed, it will displace and stretch the multiple springs 42. When the hard bristles 553 are separated from the dust-proof net 43, the multiple springs 42 drive the dust-proof frame 46 to return to its original position, thereby driving the dust-proof net to shake, and thus shaking off some of the adsorbed dust for cleaning;

[0050] Moreover, during the cleaning process, the dust-proof net 43 can also be steam-cleaned by heating the water in the water absorption core 5. An instruction is sent to the heating module 6 through the console to control the rapid temperature rise of the graphene heating sheet channel, transfer the heat to the surrounding air, and control the reverse blowing of the fan device 7. The indoor air enters the ventilation duct 1 through the air filtration device 3. When passing through the heating module 6, the air is heated. When the hot air passes through the water absorption core, the water absorbed inside the water absorption core is heated and evaporated. The evaporated water vapor follows the air and is discharged through the dust-proof net 43. When the water vapor passes through the dust-proof net 43, part of it is adsorbed on the surface and combines with the dust to form mixed water droplets. As the water droplets increase, they form sewage and fall into the dust discharge groove 12 and then into the dust discharge pipe 8. The sewage on the other side of the dust-proof net 43 falls into the drainage groove 5 and enters the dust discharge pipe 8 through the connecting hose 45, and is finally collected by the collection box.

[0051] After reaching the set cleaning time, the console controls the steering gear 52 to drive the second mounting frame 53 to flip and overlap with the transmission frame 51, and then stop working. The fan device 7 and the heating module 6 stop working.
