Description

Technical Field

[0001] This utility model relates to the field of building ventilation structure technology, specifically a ventilation system for green buildings. Background Technology

[0002] With increasing environmental awareness and more urgent requirements for building energy efficiency, green building has become a topic of great interest. In green building design, ventilation and energy-saving systems are a crucial component.

[0003] Currently, traditional ventilation energy-saving systems consist of an air purification module, a ventilation module, an intelligent air monitoring module, and an energy recovery module. In order to ensure the quality of the air entering the room, the air purification module usually uses a filter or filter screen to filter the air. However, during long-term use, a lot of dust will accumulate on the filter mechanism, resulting in a reduction in air intake and an increase in ventilation energy consumption. The only option is to replace or clean the filter mechanism, which is extremely inconvenient. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a ventilation system for green buildings includes an air inlet box 1. One end of the air inlet box 1 is connected to an air inlet pipe 2, and the other end of the air inlet box 1 is connected to an air supply pipe 4. A door is hinged to the outside of the air inlet box 1. An air inlet louver 3 is fixedly installed at one end of the air inlet pipe 2. A fan 7 is installed inside the air inlet box 1 near the air supply pipe 4. A filter screen 8 is installed inside the middle of the air inlet box 1. A dust collection box 6 is connected to the bottom of the air inlet box 1 near the filter screen 8. A back-blowing mechanism is installed on the top of the air inlet box 1. After the fan 7 is started, outside air enters the air inlet pipe 2 through the air inlet louver 3, is filtered by the filter screen 8, and is then transported to the air supply pipe 4 by the fan 7. Clean air is then transported to the room through the air supply pipe 4.

[0022] Two symmetrically arranged first connecting plates 9 are fixedly connected inside the air inlet box 1 near the air supply pipe 4. The top and bottom of the fan 7 are connected to the adjacent first connecting plates 9 by screws. A second connecting plate 10 is fixedly connected inside the middle of the air inlet box 1. The top and bottom of the filter screen 8 are connected to the adjacent second connecting plate 10 by screws. The first connecting plate 9 and the second connecting plate 10 can be used to fix the fan 7 and the filter screen 8 respectively, and facilitate subsequent disassembly and maintenance.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the backflush mechanism includes a connecting seat 12 and an air tank 5. The connecting seat 12 is fixedly connected to the top of the air inlet box 1, and the air tank 5 is fixedly connected to the inner side of the top of the connecting seat 12. Several first connecting pipes 13 are connected to the outer side of the air tank 5, and one end of each first connecting pipe 13 is connected to an electromagnetic pulse valve 11.

[0024] The output end of the electromagnetic pulse valve 11 is connected to a second connecting pipe 14. One end of the second connecting pipe 14 is fixedly connected to the inside of the air inlet box 1, and several blow pipes 15 are connected to the outside of the second connecting pipe 14. When the electromagnetic pulse valve 11 is opened, the compressed gas in the air tank 5 enters the electromagnetic pulse valve 11 through the first connecting pipe 13, then enters the second connecting pipe 14 for diversion, and finally sprays out from the blow pipes 15. The resulting airflow blows towards the filter screen 8, and the dust accumulated on the other side of the filter screen 8 is shaken off, thereby cleaning the filter screen 8.

[0025] Among the several second connecting pipes 14, the blow pipes 15 on the second connecting pipes 14 near both ends of the filter screen 8 are set at an angle. Since the edge of the filter screen 8 is a frame, this setting can make the outlet end of the blow pipe 15 face the mesh of the filter screen 8.

[0026] like Figure 1 and Figure 4 As shown, the top of the dust collection box 6 is inverted triangular in shape, which can guide the dust and cause the dust shaken off by the back-blowing mechanism to concentrate at the bottom of the dust collection box 6. A dust cleaning door is hinged to one side of the bottom of the dust collection box 6, and an electric push rod 16 is fixedly connected to the other side of the bottom of the dust collection box 6.

[0027] The output end of the electric push rod 16 is fixedly connected to a push plate 17. The push plate 17 is located inside the dust collection box 6, and the outer wall of the push plate 17 is in close contact with the inner wall of the dust collection box 6. When cleaning dust, the user can open the dust removal door and start the electric push rod 16. The output end of the electric push rod 16 extends, driving the push plate 17 to move at the bottom of the dust collection box 6. During the movement of the push plate 17, the dust in the bottom of the dust collection box 6 can be pushed out from the dust removal door.

[0028] This utility model provides a ventilation system for green buildings. The specific working principle is as follows: After the fan 7 is started, outside air enters the air inlet duct 2 through the air inlet louver 3, is filtered by the filter screen 8, and is then transported to the air supply duct 4 by the fan 7. The clean air is then transported to the room through the air supply duct 4.

[0029] When the filter screen 8 needs to be cleaned, the electromagnetic pulse valve 11 can be activated. The compressed gas in the air tank 5 enters the electromagnetic pulse valve 11 through the first connecting pipe 13, then enters the second connecting pipe 14 for diversion, and finally sprays out from the blow pipe 15. The resulting airflow will blow towards the filter screen 8, and the dust accumulated on the other side of the filter screen 8 will be shaken off, thus cleaning the filter screen 8. The shaken-off dust will be concentrated in the dust collection box 6. When the user needs to clean the dust, the dust removal door can be opened and the electric push rod 16 can be activated. The output end of the electric push rod 16 extends, driving the push plate 17 to move at the bottom of the dust collection box 6. During the movement of the push plate 17, the dust in the bottom of the dust collection box 6 can be pushed out from the dust removal door.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
