Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, specifically to a ventilation device with adjustable ventilation volume. Background Technology

[0002] Ventilation devices are widely used in industrial production and daily life, effectively improving indoor air quality by expelling stale air and introducing fresh air, ensuring personnel health and equipment operation. However, existing ventilation devices generally suffer from the problem of inflexible airflow adjustment. For example, in workshops or warehouses, the demand for ventilation varies significantly depending on the time of day and working conditions. Traditional ventilation devices either operate at a fixed volume, unable to adjust according to actual needs, leading to energy waste or poor ventilation; or their adjustment methods are complex and inconvenient, requiring frequent manual disassembly and installation of components, greatly impacting work efficiency and increasing labor costs. Furthermore, existing ventilation devices also have shortcomings in airflow guidance and filtration. Airflow within ventilation ducts is obstructed, filter installation and removal are inconvenient, and cleaning and maintenance are difficult, further limiting the practical performance and lifespan of the ventilation devices. Therefore, a new ventilation device with adjustable airflow has become an urgent problem for those skilled in the art to solve. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] This application provides a ventilation device with adjustable ventilation volume, comprising:

[0024] A ventilation assembly 1 is installed at the front end of a fan. The ventilation assembly 1 is provided with a ventilation pipe 2, a filter screen 3 and a flange connector 4. One end of the ventilation pipe 2 is detachably connected to the flange connector 4, and the other end is connected to the filter screen 3. The filter screen 3 can filter the air entering the ventilation device, remove dust, impurities and other contaminants, and ensure the cleanliness of the exhaust air.

[0025] A spiral guide tube 10 is provided on the inner wall of the ventilation duct 2. The cross-section of the spiral guide tube 10 is set as a semi-circle. The spiral guide tube 10 can guide the air to flow spirally in the ventilation duct 2, making the air distribution more uniform, reducing the generation of eddies, and improving ventilation efficiency.

[0026] The connecting plate 5 is installed on the outer side of the ventilation pipe 2 near the filter screen 3. The connecting plate 5 is detachably connected to the ventilation pipe 2. The connecting plate 5 is used to provide an installation base for the air outlet plate 6 and the adjustment component 1. The hollow inner diameter of the connecting plate 5 is adapted to the inner diameter of the ventilation pipe 2 to ensure that air can pass through smoothly and will not generate large wind resistance due to changes in the inner diameter.

[0027] The hollow inner diameter of the connecting plate 5 is adapted to the inner diameter of the ventilation pipe 2.

[0028] The connecting plate 6 has several stabilizing holes arranged in a ring, and the adjusting rod 8 is installed through the stabilizing holes.

[0029] The filter 3 is connected to the inner wall of the ventilation duct 2 by a snap-fit ​​method.

[0030] An air outlet plate 6 is installed at the end of the connecting plate 5 away from the ventilation component 1. Several sets of adjustment components 7 are arranged between the air outlet plate 6 and the ventilation pipe 2, and the distance is adjusted by the adjustment components 7. The several sets of adjustment components 7 are arranged in a ring. Each adjustment component 7 consists of an adjustment rod 8 and a cylinder 9. The adjustment rod 8 is installed through the connecting plate 5, and one end of the adjustment rod 8 is connected to the cylinder 9, and the other end is connected to the air outlet plate 6.

[0031] The adjusting rod 8 is configured as a multi-section electric telescopic rod, and its model can be YH8-528 multi-section electric telescopic rod.

[0032] The cross-section of the air outlet plate 6 is adapted to the cross-section of the connecting plate 5.

[0033] An external controller is connected to the cylinder 9 to control the start and stop of the cylinder 9. When the controller controls the cylinder 9 to work, the cylinder 9 pushes or pulls the adjusting rod 8, which in turn drives the air outlet plate 6 to move, changing the distance between the air outlet plate 6 and the ventilation pipe 2, thereby realizing the adjustment of the ventilation volume.

[0034] It is worth noting that when the ventilation device is needed, the ventilation assembly 1 is first connected to other piping equipment via the flange connector 4. Air enters the ventilation assembly 1 under the action of the fan, passes through the ventilation duct 2, and within the ventilation duct 2, the spiral guide pipe 10 guides the air in a spiral flow, making the air distribution more uniform. Then, the air passes through the filter screen 3, which filters out dust, impurities, and other contaminants. Next, according to the actual required ventilation volume, the external controller controls the cylinder 9. If an increase in ventilation volume is needed, the controller activates the cylinder 9, pushing the adjusting rod 8. The adjusting rod 8 moves the air outlet plate 6 away from the ventilation assembly 1, increasing the distance between the air outlet plate 6 and the ventilation duct 2, thereby increasing the ventilation volume. If a decrease in ventilation volume is needed, the controller activates the cylinder 9, pulling the adjusting rod 8. The adjusting rod 8 moves the air outlet plate 6 closer to the ventilation assembly 1, decreasing the distance between the air outlet plate 6 and the ventilation duct 2, thereby reducing the ventilation volume. When the filter 3 needs to be cleaned or replaced after a period of use, simply remove the filter 3 from the clip on the inner wall of the ventilation duct 2. After cleaning or replacement, reinstall the filter 2 in its original position using the snap-fit ​​connection.

[0035] The above description is merely a few embodiments of this application and is not intended to limit this application in any way. Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
