Description

Technical Field

[0001] This utility model relates to the field of fresh air device technology, and in particular to a fresh air device with air purification function. Background Technology

[0002] A fresh air system is an indoor environmental management system that integrates ventilation and deep purification. Its core function is to achieve the circulation and renewal of indoor and outdoor air through scientific airflow organization, while efficiently filtering pollutants to create a healthy breathing environment for modern living. It actively introduces fresh outdoor air through a fan system and simultaneously exhausts stale indoor air, forming a dynamically balanced "fresh air flow field." During the air exchange process, outdoor air undergoes multiple filtration systems: a pre-filter intercepts large particles of dust, hair, and other impurities; a high-efficiency HEPA filter captures fine particulate matter such as PM2.5 and pollen, with a filtration efficiency of over 97%. Compared to traditional air purifiers that only circulate and purify indoor air, fresh air systems address the problems of increased carbon dioxide concentration and insufficient oxygen at the source, making them particularly suitable for long-term use in enclosed spaces. Therefore, fresh air systems generally bring in both outdoor and indoor air. However, because outdoor air contains a large amount of dust, leaves, and other pollutants, excessive accumulation of these larger pollutants can cause duct blockage. Therefore, filter plates are needed for protection, and regular cleaning is required. Utility Model Content

[0003] In view of this, the present invention aims to provide a fresh air device with air purification function to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0004] The technical solution of this utility model embodiment is implemented as follows: it includes an air inlet pipe and an air outlet pipe, one end of which is connected by a guide pipe. A primary filter plate is fixedly connected to one end of the air inlet of the air inlet pipe. Multiple wind baffles are rotatably connected to the inner sides of the air inlet pipe and the air outlet pipe respectively. A guide baffle is rotatably connected to the inner side of the guide pipe. Two sealing bosses are fixedly connected to the inner side of the guide pipe. The two sides of the guide baffle are attached to the sealing bosses. A synchronous pulley set is fixedly connected above one of the wind baffles and the guide baffle installed in the air inlet pipe or the air outlet pipe. The two synchronous pulley sets are connected by a synchronous belt. A flip motor is fixedly connected above the guide pipe. The output shaft of the flip motor is fixedly connected to the synchronous pulley set. A synchronous component is fixedly connected above the wind baffle.

[0005] In some embodiments, the synchronization component includes a synchronization gear and a synchronization rack. The synchronization gear is fixedly connected to the top of the windshield blade, and the synchronization rack is slidably connected to the upper side of the air inlet pipe or air outlet pipe. Multiple synchronization gears mesh on one side of the synchronization rack.

[0006] In some embodiments, a main control component is fixedly connected to one side of the air inlet pipe and the air outlet pipe. The main control component controls electronic components connected to the device. An air intake fan is fixedly connected inside the air inlet pipe, and an exhaust fan is fixedly connected inside the air outlet pipe.

[0007] In some embodiments, an electric switch is fixedly connected inside the air inlet pipe and the air outlet pipe respectively, and a secondary filter element and a tertiary filter element are fixedly connected to one side of the air inlet pipe.

[0008] In some embodiments, one end of the air guide pipe is fixedly connected to a backflush pipe, the outlet of the backflush pipe is fixedly connected to a backflush nozzle, the backflush nozzle is slidably connected inside the air inlet pipe, and the outlet of the backflush nozzle is attached to one side of the primary filter plate.

[0009] In some embodiments, a lifting push rod is fixedly connected above the air inlet pipe, and the movable end of the lifting push rod is fixedly connected to the backflushing nozzle.

[0010] In some embodiments, a drain baffle is rotatably connected to the bottom of the air inlet pipe, and a bevel gear two is fixedly connected below the wind deflector blade installed on one side of the air inlet pipe. One end of the bevel gear two meshes with a bevel gear one, and the other end of the bevel gear one is rotatably connected to the bottom of the air inlet pipe.

[0011] In some embodiments, the sewage baffle and the bevel gear are respectively fixedly connected to one side of a baffle synchronous pulley, and one end of the multiple baffle synchronous pulleys is connected by a synchronous belt.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] 1. A fresh air device with air purification function, which realizes airflow switching through the linkage design of air guide baffle and wind deflector blade. When the primary filter plate needs to be cleaned, the flip motor drives the air guide baffle to rotate, and at the same time, the wind deflector blade is driven to rotate synchronously through the synchronous pulley group and synchronous belt, so that the airflow reverses and passes through the primary filter plate to achieve automatic backflushing cleaning, which solves the problem of easy clogging of traditional filters.

[0014] 2. A fresh air device with air purification function, wherein a back-blowing nozzle driven by a lifting push rod works in conjunction with an air duct to clean the system. The back-blowing nozzle increases the airflow velocity by reducing the cross-sectional area of ​​the air outlet, and performs targeted high-pressure back-blowing on the primary filter plate during the lifting process, effectively improving the cleaning effect.

[0015] 3. A fresh air device with air purification function, wherein the drain baffle and the wind deflector are mechanically linked by a bevel gear set and a synchronous belt, and the drain port is automatically opened during backwashing cleaning, so that the removed dirt is directly discharged outside the device, avoiding secondary pollution and keeping the inside of the air inlet pipe clean.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1:

[0028] like Figure 1-5 As shown, a fresh air device with air purification function includes an air inlet pipe 1 and an air outlet pipe 2. The air inlet pipe 1 and the air outlet pipe 2 are shaped like "[" to prevent airflow short-circuiting. The air just introduced into the room is discharged from the air outlet pipe 2. One end of the air inlet pipe 1 and the air outlet pipe 2 are connected by an air guide pipe 12. A primary filter plate 9 is fixedly connected to one end of the air inlet of the air inlet pipe 1. The primary filter plate 9 is a filter plate with a large pore size, used to filter larger particles such as leaves in the air. Multiple wind baffles 14 are rotatably connected to the inner side of the air inlet pipe 1 and the air guide pipe 12. An air guide baffle 21 is rotatably connected to the inner side of the air guide pipe 12. Two sealing bosses 20 are fixedly connected. The air guide baffle 21 is attached to the sealing bosses 20 on both sides. A synchronous pulley set 17 is fixedly connected above the wind deflector blade 14 installed in the air inlet pipe 1 or the air outlet pipe 2 and the air guide baffle 21. The synchronous pulley set 17 is composed of two identical rollers. The two synchronous pulley sets 17 are connected by a synchronous belt 18. The two synchronous belts 18 realize the synchronous rotation of the three synchronous pulley sets 17. A flip motor 19 is fixedly connected above the air guide pipe 12. The output shaft of the flip motor 19 is fixedly connected to the synchronous pulley set 17. A synchronous component is fixedly connected above the wind deflector blade 14.

[0029] The synchronization component includes a synchronization gear 15 and a synchronization rack 16. The synchronization gear 15 is fixedly connected to the top of the wind deflector blade 14, and the synchronization rack 16 is slidably connected to the upper side of the air inlet pipe 1 or the air outlet pipe 2. Multiple synchronization gears 15 mesh with one side of the synchronization rack 16.

[0030] When the wind deflector 14 at one end rotates, it will drive the synchronous gear 16 to move through the synchronous gear 15 above, thereby driving all the wind deflectors 14 below the synchronous gears 15 to rotate synchronously, which can achieve the sealing and unobstructed flow of the air inlet pipe 1 and the air outlet pipe 2.

[0031] When the device is working normally, fresh air from the outside is introduced through the air inlet pipe 1, and the internal gas is discharged outward through the air outlet pipe 2. At this time, the air guide baffle 21 inside the air guide pipe 12 fits against the sealing protrusions 20 on both sides, preventing the airflow from passing through the air guide pipe 12.

[0032] When it is necessary to clean the primary filter plate 9, the flip motor 19 can be started to drive the air guide baffle 21 below to rotate 90 degrees. Then, through the synchronous pulley group 17, synchronous belt 18 and synchronous assembly, multiple baffle blades 14 installed in the air inlet pipe 1 and air outlet pipe 2 are driven to rotate synchronously, blocking the air outlet side of the air outlet pipe 2 and the air inlet side of the air inlet pipe 1.

[0033] At this time, the airflow that should have been discharged from the air outlet 2 will pass through the air guide pipe 12, and then through the first-stage filter plate 9 and be discharged from the air outlet of the air inlet 1, thereby achieving backflushing and cleaning of the first-stage filter plate 9.

[0034] In this embodiment, a main control component 3 is fixedly connected to one side of the air inlet pipe 1 and the air outlet pipe 2. The main control component 3 is equipped with a control chip, a wireless information transmission component, and other components for control and signal transmission. The control and signal transmission method is the existing technology. The main control component 3 is connected to the electronic components inside the device. An air intake fan 5 is fixedly connected inside the air inlet pipe 1, and an exhaust fan 6 is fixedly connected inside the air outlet pipe 2.

[0035] The intake fan 5 and the exhaust fan 6 can achieve airflow exchange;

[0036] An electric switch 4 is fixedly connected inside the air inlet pipe 1 and the air outlet pipe 2 respectively. A secondary filter element 7 and a tertiary filter element 8 are fixedly connected to one side of the air inlet pipe 1.

[0037] The secondary filter element 7 and the tertiary filter element 8 can further filter the intake air. Activated carbon and other substances can be installed inside for multi-dimensional filtration. At the same time, the secondary filter element 7 and the tertiary filter element 8 are installed on the indoor side of the air intake duct 1 for easy disassembly.

[0038] In this embodiment, one end of the air guide pipe 12 is fixedly connected to a backflush pipe 13, the air outlet of the backflush pipe 13 is fixedly connected to a backflush nozzle 10, the backflush nozzle 10 is slidably connected to the inside of the air inlet pipe 1, the air outlet of the backflush nozzle 10 is attached to one side of the primary filter plate 9, a lifting push rod 11 is fixedly connected above the air inlet pipe 1, and the lower movable end of the lifting push rod 11 is fixedly connected to the backflush nozzle 10.

[0039] The backflush pipe 13 is a flexible pipe. When the electric lifting push rod 11 extends or retracts, it can drive the backflush nozzle 10 below to adhere to the primary filter plate 9 for backflush. Because the cross-sectional area of ​​the air outlet of the backflush nozzle 10 is smaller than that of the air guide pipe 12, the airflow ejected by the backflush nozzle 10 is faster and the backflush effect is better.

[0040] In this embodiment: the intake fan 5 and the exhaust fan 6 can replace the airflow; the secondary filter element 7 and the tertiary filter element 8 can further filter the intake air. Activated carbon and other substances can be installed inside for multi-dimensional filtration. At the same time, the secondary filter element 7 and the tertiary filter element 8 are installed on the indoor side of the air intake pipe 1, which is easy to disassemble.

[0041] When the device is working normally, fresh air from the outside is introduced through the air inlet pipe 1, and the internal gas is discharged outward through the air outlet pipe 2. At this time, the air guide baffle 21 inside the air guide pipe 12 fits against the sealing protrusions 20 on both sides, preventing the airflow from passing through the air guide pipe 12.

[0042] When it is necessary to clean the primary filter plate 9, the flip motor 19 can be started to drive the air guide baffle 21 below to rotate 90 degrees. Then, through the synchronous pulley group 17, synchronous belt 18 and synchronous assembly, multiple baffle blades 14 installed in the air inlet pipe 1 and air outlet pipe 2 are driven to rotate synchronously, blocking the air outlet side of the air outlet pipe 2 and the air inlet side of the air inlet pipe 1.

[0043] At this time, the airflow that should have been discharged from the air outlet 2 will pass through the air guide pipe 12, and then through the first-stage filter plate 9 and be discharged from the air outlet of the air inlet 1, thereby achieving backflushing and cleaning of the first-stage filter plate 9.

[0044] The backflush pipe 13 is a flexible pipe. When the electric lifting push rod 11 extends or retracts, it can drive the backflush nozzle 10 below to adhere to the primary filter plate 9 for backflush. Because the cross-sectional area of ​​the air outlet of the backflush nozzle 10 is smaller than that of the air guide pipe 12, the airflow ejected by the backflush nozzle 10 is faster and the backflush effect is better.

[0045] Example 2:

[0046] A fresh air device with air purification function is provided in this embodiment, which is improved based on embodiment 1 as follows: Figure 1-5 As shown,

[0047] In this embodiment, a drain baffle 23 is rotatably connected to the bottom of the air inlet pipe 1, and a bevel gear 26 is fixedly connected below the wind baffle blade 14 installed on one side of the air inlet pipe 1. One end of the bevel gear 26 meshes with a bevel gear 22, and the other end of the bevel gear 22 is rotatably connected to the bottom of the air inlet pipe 1.

[0048] One side of the sewage discharge baffle 23 and the bevel gear 22 are respectively fixedly connected to baffle synchronous pulleys 24, and one end of the multiple baffle synchronous pulleys 24 are connected by synchronous belt 25.

[0049] While performing backwash cleaning, the wind deflector 14 on one side rotates, which drives the bevel gear 26 below to rotate. This, in turn, drives the drain baffle 23 at the other end to rotate through the baffle synchronous pulley 24 and the synchronous belt 25. This allows the dirt blown out from one end of the primary filter plate 9 to be discharged from the slot opened after the drain baffle 23 rotates, preventing dirt from accumulating in the air inlet pipe 1.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
