Description

Technical Field

[0001] This utility model relates to the field of negative pressure air sources, specifically to a negative pressure air source assembly device. Background Technology

[0002] A negative pressure air source is a device that uses a positive pressure air source (such as compressed air) to generate a stable negative pressure (vacuum). Its core working principle is the Venturi effect: when compressed air passes through a narrow nozzle at high speed, the flow velocity increases sharply, causing the pressure in the chamber behind the nozzle to drop rapidly, thus creating a vacuum suction. This device is compact, requires no electricity, has a fast response speed, and, due to the absence of moving mechanical parts, offers significant advantages such as maintenance-free operation and a long service life. It typically integrates filters and vacuum switches and is widely used in industrial automation, such as vacuum gripping and adsorption handling of workpieces like plastics, glass, and thin metal sheets. It is an ideal pneumatic component for achieving efficient and precise automated production.

[0003] Chinese patent CN222910379U discloses a vacuum generator, including a valve body. One side of the valve body is connected to an air inlet, and the other side is connected to an exhaust outlet. The lower end of the valve body also has a connecting portion. The air inlet has a first air passage, a second air passage, and a third air passage inside. The exhaust outlet has a fourth air passage inside. The first, second, and third air passages form a Laval tube structure, and the inner diameter of the fourth air passage is larger than the outer diameter of the third air passage. The connecting portion connects to the third and fourth air passages via a fifth air passage. When compressed gas passes through the Laval tube structure, it releases airflow into the fourth air passage. The high-speed airflow causes a negative pressure to form in the fifth air passage, allowing the device to achieve negative pressure through airflow. Based on this, the device achieves vacuum capability while possessing advantages such as simple structure, small size, and ease of use. However, the device still has the following problems. If you want to adjust the adsorption force during the use of this device, you need to adjust the airflow output power of the air compressor. However, the air compressor has an unstable output period when adjusting the output power, which affects the working efficiency.
