Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, specifically to an intelligent building ventilation device. Background Technology

[0002] Building intelligence uses buildings as a platform and is based on the comprehensive application of various intelligent information. It integrates architecture, systems, applications, management, and optimization, and has comprehensive intelligent capabilities such as perception, transmission, memory, reasoning, judgment, and decision-making. When people sleep or rest in a building, if it is raining outside and windows need to be closed or the room itself has poor ventilation, the concentration of carbon dioxide in the room may increase significantly due to human respiration. Excessive air humidity will also affect comfort. At the same time, formaldehyde has a long volatilization time after building decoration, and poor air circulation will increase the concentration of formaldehyde, which will harm human health.

[0003] Existing building ventilation systems have the following drawbacks:

[0004] 1. The replacement of filter elements in existing building ventilation systems is inconvenient, requiring the disassembly of the ventilation system housing to replace the filter elements, resulting in slow filter element replacement efficiency.

[0005] 2. When existing building ventilation systems ventilate in winter, cold air enters the room, causing the indoor temperature to drop and affecting user comfort.

[0006] Therefore, a solution is needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1

[0025] Regarding the problem 1 that needs to be solved above: the replacement of filter elements in existing building ventilation systems is inconvenient, requiring the disassembly of the ventilation system casing to replace the filter elements, resulting in slow filter element replacement efficiency.

[0026] The solution is as follows: A building intelligent ventilation device includes a device body 1, which includes an exhaust duct 2, an intake duct 3, an input fan assembly 4, an output fan assembly 5, and a portable filter device 7. The intake duct 3 is installed at the top of the exhaust duct 2, the input fan assembly 4 is installed at the rear end of the intake duct 3, and the output fan assembly 5 is installed at the rear end of the exhaust duct 2. A sliding groove 6 is provided on the right side of the intake duct 3. The sliding groove 6 has an I-shaped structure. The portable filter device 7 is installed in the sliding groove 6 and located inside the intake duct 3. The portable filter device 7 includes a filter mounting frame 8, a top slider 9, and a bottom slider 10. The filter mounting frame 8 has a rectangular structure, and a filter element 11 is installed inside the filter mounting frame 8. The top slider 9 and bottom slider 10 are rectangular in shape. The top slider 9 is installed on the top of the filter mounting frame 8, and the bottom slider 10 is installed on the bottom of the filter mounting frame 8. In use, the output fan group 5 draws in external air and delivers it to the portable filter device 7. After the air passes through the filter element 11 of the filter mounting frame 8, it can be filtered by the filter element 11. If the portable filter device 11 needs to be maintained, the operator can manually pull the operating handle 12, and then the top slider 9 and bottom slider 10 in the portable filter device 11 can slide out in the sliding groove 6. The operator only needs to replace the filter element 11 on the filter mounting frame 8, and then the portable filter device 7 can be reinstalled in the sliding groove 6 of the air inlet duct 3 by insertion.

[0027] The filter mounting frame 8 is provided with an operating handle 12 on the right end. The operating handle 12 has a U-shaped structure and is located on the outside of the air inlet duct 3. The operator can manually pull the operating handle 12 to remove the entire portable filter device 7 from the air inlet duct 3, thereby achieving maintenance of the portable filter device 7.

[0028] The exhaust duct 2 and the air inlet duct 3 are equipped with a guide device 13 at their front ends. The guide device 13 includes a rotating shaft 14 and an operating motor 15. The driving end of the operating motor 15 is connected to one end of the rotating shaft 14. The upper and lower ends of the rotating shaft 14 are equipped with guide blades 16. The guide blades 16 have a rectangular structure. When the exhaust duct 2 and the air inlet duct 3 are opened or guided, the operator starts the operating motor 15 in the guide device 13. The operating motor 15 can drive the rotating shaft 14 to rotate, and then the guide blades 16 on the rotating shaft 14 can be driven, thereby opening or closing the exhaust duct 2 and the air inlet duct 3.

[0029] Example 2

[0030] Regarding the second problem to be solved above: When existing building ventilation systems ventilate in winter, cold air enters the room, causing the indoor temperature to drop and affecting user comfort.

[0031] The solution is as follows: A heating device 17 is installed inside the air inlet duct 3. The heating device 17 is located at the front end of the portable filter device 7. The heating device 17 includes a heating frame 18 and heating wires 19. Several groups of heating wires 19 are installed in the heating frame 18 in a horizontally equidistant manner. When the filtered air in the air inlet duct 3 is heated, the heating wires 19 in the heating frame 18 will be energized and generate heat. When the air passes through, it can carry away the heat on the heating wires 19, thereby increasing the temperature of the air discharged into the room.

[0032] Working principle: During operation, the output fan group 5 draws in external air and delivers it to the portable filter device 7. After passing through the filter element 11 of the filter mounting frame 8, the air is filtered by the filter element 11. When heating the filtered air in the air inlet duct 3, the heating wire 19 in the heating frame 18 will be energized and heat up. When the air passes through, it can carry away the heat on the heating wire 19, thereby increasing the temperature of the air discharged into the room. (If it is necessary to increase the airflow, an input fan group can be added in the air inlet duct 3 and an output fan group 5 can be added in the air outlet duct 2). If the portable filter device 11 needs to be maintained, the operator can manually pull the operating handle 12, and then the top slider 9 and bottom slider 10 in the portable filter device 11 can slide out in the sliding groove 6. The operator only needs to replace the filter element 11 on the filter mounting frame 8, and then the portable filter device 7 can be reinstalled in the sliding groove 6 of the air inlet duct 3 by insertion.

[0033] The present invention comprises: 1. Device body; 2. Exhaust duct; 3. Inlet duct; 4. Input fan assembly; 5. Output fan assembly; 6. Sliding groove; 7. Portable filter device; 8. Filter mounting frame; 9. Top slider; 10. Bottom slider; 11. Filter element; 12. Operating handle; 13. Guide device; 14. Rotating shaft; 15. Operating motor; 16. Guide fan blade; 17. Heating device; 18. Heating frame; 19. Heating wire. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that the filter element replacement in existing building ventilation devices is inconvenient, requiring disassembly of the ventilation device casing to replace the filter element, resulting in slow filter element replacement efficiency. This invention, through the combination of the above components, facilitates the replacement and maintenance of the filter element in the ventilation device by the staff, thereby reducing the burden of maintenance on the staff and improving the efficiency of ventilation device maintenance.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
