Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, and more specifically, to a building automation ventilation system. Background Art

[0002] The ventilation system of a building plays a crucial role in ensuring the comfort and health of the living environment of residents. The traditional indoor ventilation method mainly relies on opening windows for ventilation. When the weather is hot, in order to maintain the indoor temperature, residents often choose to close the windows and turn on the air conditioner. Although this behavior brings coolness indoors, it also sacrifices the fluidity of indoor air.

[0003] Chinese Patent CN217929086 U proposes a building ventilation device. The device aims to improve the air circulation in the building through automated means, and keep the indoor air fresh and circulating even when the weather is hot. However, during actual use, the applicant found that if the filter cotton is not replaced in time, dust will gradually adhere to the filter cotton, resulting in a decrease in the porosity of the filter cotton, and then a decrease in the air volume. The decrease in air volume not only affects the overall performance of the ventilation device, but also increases energy consumption, because the system needs to consume more energy to overcome the resistance brought by the filter cotton. More seriously, if the filter cotton is not replaced for a long time, a part of the dust will penetrate the filter cotton and remain in the device body. The long-term accumulation of these dusts will not only affect the operation efficiency and service life of the device, but also may become a breeding ground for microorganisms such as bacteria and viruses, causing secondary pollution to the indoor air quality.

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the accompanying drawings and embodiments:

[0017] As Figure 1 - Figure 2 shown, a building automation ventilation system includes a ventilation pipe body 1. The left side of the ventilation pipe body is an air inlet 11, and the right side of the ventilation pipe body is an air outlet 12. Such a design enables air to smoothly flow in from the air inlet, and after being filtered and processed, flow out from the air outlet, realizing the circulation and update of indoor air. A support frame 21 is provided inside the ventilation pipe body. A driving fan blade 22 is rotatably connected to the support frame. A filtering component is installed inside the ventilation pipe body. The filtering component includes a first support and a second support. A first rotating shaft 51 is provided on the first support, and a first driving roller 52 is rotatably connected to the first rotating shaft. A second rotating shaft 53 is provided on the second support, and a second driving roller 54 is rotatably connected to the second rotating shaft. Such a design of the driving roller can effectively support and drive the filter cotton belt, ensuring its stable operation. A driving motor 55 is provided on the second support, and the output shaft of the driving motor is connected to the second driving roller. The driving motor provides power for the movement of the filter cotton belt. The first driving roller and the second driving roller are drivingly connected through a filter cotton belt 56. The filter cotton belt can effectively filter dust and impurities in the air, improving the indoor air quality. A dust-removing elastic piece 62 is provided at the bottom of the inner wall of the ventilation pipe body. The design of the dust-removing elastic piece helps to remove the dust on the filter cotton belt and maintain its filtering effect. A falling hole 102 is provided at the bottom of the ventilation pipe body, and a dust storage box 73 is provided directly below the falling hole. The design of the falling hole and the dust storage box enables the removed dust to be conveniently collected and processed, keeping the system clean.

[0018] In at least one embodiment, a driven frame 31 is provided between the support frame and the filtering component. A first motor 32 is provided on the driven frame, and the output shaft of the first motor is connected to a driven fan blade 33. The design of the driven fan blade can further enhance the ventilation effect and improve the air circulation efficiency.

[0019] In at least one embodiment, a filter plate 4 is provided at the air inlet. The cross-section of the filter plate in the vertical direction is corrugated. The design of the corrugated filter plate can effectively block garbage from entering the ventilation system, and at the same time reduce the accumulation of garbage on the filter plate, keeping the air inlet clean.

[0020] In at least one embodiment, a rectangular notch 101 for the filter cotton belt to pass through is provided on the ventilation pipe body.

[0021] In at least one embodiment, a connecting plate 61 is provided at the bottom of the inner wall of the ventilation pipe body. A dust removal elastic piece 62 is provided on the connecting plate. An installation hole is provided on the dust removal elastic piece. A bolt 63 is provided in the installation hole. After passing through the installation hole, the bolt is threadedly connected to the threaded hole of the connecting plate. Rotating the bolt can make the end of the dust removal elastic piece abut against the surface of the filter cotton belt. Such a design enables the angle and force of the dust removal elastic piece to be adjustable, can better adapt to filter cotton belts of different thicknesses and materials, and improves the dust removal effect.

[0022] In at least one embodiment, a vertical plate 71 is provided at the bottom of the ventilation pipe body. A horizontal plate 72 is provided on the vertical plate. A dust storage box is slidably supported on the two horizontal plates. When the drive motor rotates, the filter cotton belt can be brought into contact with the dust removal elastic piece, so that the dust attached to the filter cotton belt falls into the dust storage box along the falling hole. The design of the slidably supported dust storage box makes the collection and treatment of dust more convenient and fast, and improves the usability and maintenance efficiency of the system.

[0023] Working method: Install the building automation ventilation system at the designated position to ensure that the air inlet 11 and the air outlet 12 correspond to the indoor and outdoor respectively. Check whether the support frame 21, the driven frame 31 (if applicable), the filter assembly (including the first support, the second support, the first driving roller 52, the second driving roller 54, the filter cotton belt 56, etc.) and the drive motor 55 in the ventilation pipe body are installed correctly. Install the filter plate 4 at the air inlet 11 to ensure that its corrugated design can correctly guide the garbage. Place the dust storage box 73 on the horizontal plate 72 to ensure that the falling hole 102 is directly opposite the dust storage box.

[0024] After the ventilation system has been running for a period of time, such as one week, start the drive motor 55 regularly to drive the second driving roller 54 to rotate, and then drive the first driving roller 52 to rotate through the filter cotton belt 56. The filter cotton belt 56 starts to circulate and filter the air passing through the ventilation pipe body. If applicable, start the first motor 32 to drive the driven fan blade 33 to rotate to enhance the ventilation effect. When there is more dust accumulated on the filter cotton belt, at this time, the dust removal elastic piece abuts against the surface of the filter cotton belt under the action of the bolt 62 to remove the dust. The dust will fall into the dust storage box 73 through the falling hole 102. Clean the dust storage box regularly to keep the system clean. Regularly check and maintain each component of the system to ensure long-term stable operation.

[0025] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification only illustrate the principles of the present utility model.
