Description

Technical Field

[0001] The present invention relates to the technical field of building ventilation and air change, and particularly to a building intelligent ventilation and air change device. Background Art

[0002] Ventilation and air change devices are widely used in homes and public places. The ventilation and air change device can discharge the turbid air inside the building through mechanical air supply, and at the same time introduce the fresh air outside the building. The main purpose of ventilation and air change is to remove the dirty air inside the building to ensure the air quality inside the building.

[0003] Currently, most ventilation and air change devices are basically installed on holes drilled in the building wall. One end of the ventilation and air change device is connected to the outside, and the other end is connected to the inside. The fresh air outside is drawn into the room through a ventilation fan. However, the part of the current ventilation and air change device outside is open. In some high-rise buildings, if there is strong wind and heavy rain, rainwater will inevitably pour into the room from the open end. At the same time, in order to filter the air, some air filtering components are installed in the current ventilation and air change device. These air filtering components need to be cleaned or replaced after working for a period of time. These air filtering components are often fixed by screwing, and the disassembly is very inconvenient. In order to improve the air quality in the room, some current ventilation and air change devices often install some sterilization and disinfection components. However, the contact area between the air and the sterilization and disinfection components in the current ventilation and air change device is small, and the sterilization and disinfection effect is not very ideal. Summary of the Invention

[0034] In this embodiment, the honeycomb filter cotton 19, the activated carbon filter layer 20, and the HEPA filter layer 21 are all plate-shaped bodies. Three slots are sequentially formed at the bottom end of the indoor part of the air duct 1. The honeycomb filter cotton 19, the activated carbon filter layer 20, and the HEPA filter layer 21 are respectively inserted and fitted into the three slots. Each group of the quick disassembly and assembly mechanisms 22 is symmetrically arranged with two on the left and right. Six quick disassembly and assembly mechanisms 22 are respectively arranged on the left and right sides of the three slots at the bottom end of the outer wall of the air duct 1. The quick disassembly and assembly mechanism 22 includes: a bracket six 2201, a hinge shaft 2202, a support arm 2203, a sliding pin seat 2204, a sliding pin 2205, and a limit pin 2206. The bracket six 2201 is fixedly connected to a corner at the bottom end of the indoor part of the air duct 1. One end of the support arm 2203 is hinged to the bracket six 2201 through the hinge shaft 2202. A sliding pin seat 2204 is fixedly connected to the outer wall of the air duct 1 at a position above the bracket six 2201. The sliding pin seat 2204 is in the shape of Ω. The sliding pin 2205 is vertically slidably connected to the inner cavity of the sliding pin seat 2204. A vertical slideway 22041 is formed in the middle of the arc-shaped outer wall of the sliding pin seat 2204. An upper card slot 22042 and a lower card slot 22043 are respectively formed on the tangential side at the top end and the bottom end of the vertical slideway 22041. The vertical slideway 22041, the upper card slot 22042, and the lower card slot 22043 form a Z-shaped channel. The limit pin 2206 is fixedly connected to the upper part of the sliding pin 2205 and is respectively matched with the vertical slideway 22041, the upper card slot 22042, and the lower card slot 22043; the support arm 2203 is in the shape of a rhombus, and the length of the outer lever arm of the support arm 2203 is less than the length of the inner lever arm. When the sliding pin 2205 is separated from the support arm 2203, the inner end of the support arm 2203 can automatically droop, so that the honeycomb filter cotton 19, the activated carbon filter layer 20, or the HEPA filter layer 21 can automatically fall. When the limit pin 2206 is clamped in the lower card slot 22043, the sliding pin 2205 presses and contacts the upper plane end of the outer side of the support arm 2203. At this time, the upper plane end of the inner side of the support arm 2203 presses and contacts the bottom end of the honeycomb filter cotton 19, the activated carbon filter layer 20, or the HEPA filter layer 21; when the limit pin 2206 is clamped in the upper card slot 22042, the sliding pin 2205 does not contact the support arm 2203.

[0035] In this embodiment, the adjustable sterilization and disinfection component includes: a connecting shaft 23, a U-shaped mounting plate 24, an ultraviolet sterilization lamp 25, a high-energy ion tube 26, a driven belt gear 27, a belt 28, a driving belt gear 29, a servo motor 30, an auxiliary wheel 31 and an auxiliary wheel shaft 32. The connecting shaft 23, the U-shaped mounting plate 24, the ultraviolet sterilization lamp 25, the high-energy ion tube 26 and the driven belt gear 27 are all provided with several. The left and right ends of the U-shaped mounting plate 24 are respectively rotatably connected to the left and right sides of the inner wall of the air duct 1 through two connecting shafts 23. Several ultraviolet sterilization lamps 25 and high-energy ion tubes 26 are alternately installed in several U-shaped mounting plates 24. A driven belt gear 27 is fixedly connected between the left side of the connecting shaft 23 and the inner wall of the air duct 1 between the U-shaped mounting plate 24. The belt 28 is respectively sleeved on several driven belt gears 27. A servo motor 30 is fixedly installed on the left side of the bottom end of the air duct 1. The output end of the servo motor 30 is fixedly connected to a driving belt gear 29. The belt 28 is also sleeved on the driving belt gear 29. The auxiliary wheel 31 is rotatably connected to the inner wall of the air duct 1 through the auxiliary wheel shaft 32. The auxiliary wheel 31 presses the outer side end of the belt 28 between the lowermost driven belt gear 27 and the driving belt gear 29. By driving the driving belt gear 29 to rotate through the servo motor 30, several driven belt gears 27 are driven to rotate through the belt 28, so as to realize the synchronous flipping of several U-shaped mounting plates 24. By controlling the rotation angle of the U-shaped mounting plate 24, the contact area between the air and the sterilization and disinfection components can be controlled to ensure the sterilization and disinfection effect. At the same time, the U-shaped mounting plate 24 can play a role in controlling the direction of the airflow blown into the room; the negative oxygen ions generated while the high-energy ion tube 26 disinfects and sterilizes the air can make people feel happy.

[0036] In this embodiment, a protective net 33 is detachably and fixedly installed at one end of the air duct 1 located indoors. The provided protective net 33 can prevent accidental contact with the sterilization and disinfection components. An embedded groove is opened on the outer wall of the air duct 1 embedded in the wall. A rubber sleeve 34 is sleeved and fixed in the embedded groove. The provided rubber sleeve 34 can ensure the whole device to a certain extent, avoid the deformation of the air duct 1 caused by the slight vibration generated during the operation of the whole device, and also play a certain role in noise reduction; an indoor sealing sleeve 35 is sleeved on the outer wall of the air duct 1 located indoors and close to the wall. The indoor sealing sleeve 35 is made of rubber. The indoor sealing sleeve 35 is detachably and fixedly connected to the wall. Since installing this device requires opening holes in the building wall, gaps will inevitably be generated when the air duct 1 is installed in the hole. The wind will blow sand, lime, etc. in the wall into the room through the gap. The provided indoor sealing sleeve 35 can well block the gap.

[0037] The operation of the entire device is controlled by an external controller and power supply. The power supply supplies power to the electric telescopic rod 6, the motor 17, the servo motor 30, the ultraviolet germicidal lamp 25, and the high-energy ion tube 26 respectively, and the controller controls the electric telescopic rod 6, the motor 17, the servo motor 30, the ultraviolet germicidal lamp 25, and the high-energy ion tube 26 respectively.

[0038] When the device is in use, first make holes in the building wall according to the size of the device, and then install the entire device on the holes. During installation, it is necessary to make the rubber sleeve 34 fit with the inner wall of the hole, and then fix the outer mounting plate 2 on the exterior wall of the building with self-tapping screws. Put the indoor sealing sleeve 35 on the side of the air duct 1 located indoors and close to the wall, and fix the indoor sealing sleeve 35 on the indoor wall with fixing screws. Connect the power supply of the entire device. At this time, the electric telescopic rod 6 props up the air duct outer sealing plate 4 to a position perpendicular to the exterior wall, and the motor 17 drives the ventilation fan blade 18 to rotate to draw the outdoor air into the room through the air inlet channel of the air duct 1. During the process of outdoor air entering the room, it passes through the honeycomb filter cotton 19, the activated carbon filter layer 20, and the HEPA filter layer 21 in sequence. The activated carbon filter layer 20 is used to remove odors, and the honeycomb filter cotton 19 and the HEPA filter layer 21 improve the air filtration effect. After the air passes through the HEPA filter layer 21, the ultraviolet germicidal lamp 25 and the high-energy ion tube 26 perform disinfection and sterilization treatment on the air. By controlling the rotation angle of the loop mounting plate 24, the contact area between the air and the disinfection and sterilization components can be controlled to ensure the disinfection and sterilization effect. At the same time, the loop mounting plate 24 can play a role in controlling the direction of the airflow blowing into the room; the negative oxygen ions generated by the high-energy ion tube 26 during the disinfection and sterilization treatment of the air can make people feel happy; in strong wind and heavy rain weather, by controlling the electric telescopic rod 6 to contract to drive the air duct outer sealing plate 4 to turn down, the air inlet channel of the air duct 1 can be completely covered to prevent rainwater from pouring into the room through the air inlet channel; when the wind is not strong, the air duct outer sealing plate 4 is controlled by the electric telescopic rod 6 to tilt downward at a certain angle. At this time, the rainwater can flow into the corresponding confluence channel 401 through the branch channel 402, thereby realizing the centralized discharge of rainwater; when the honeycomb filter cotton 19, the activated carbon filter layer 20, or the HEPA filter layer 21 needs to be cleaned or replaced after working for a period of time, the limit pins 2206 on the left and right sides of the corresponding filter component are snapped into the upper slot 22042. At this time, the sliding pin 2205 does not contact the support arm 2203; the support arm 2203 automatically droops under its own gravity. At this time, the honeycomb filter cotton 19, the activated carbon filter layer 20, or the HEPA filter layer 21 can be pulled out from top to bottom by hand, and the operation is convenient and fast.
