Problems solved by technology

[0002] Vacuum generators are widely used in broadcasting, communication, television, radar, navigation, industrial automation, machinery, electronics, packaging, printing, plastics and robots. Vacuum generators need to absorb and transport various materials, especially suitable for adsorption Fragile, soft, thin non-ferrous, non-metallic materials or spherical objects, ordinary vacuum generators use vacuum pumps driven by motors, which generate high energy consumption, large volume, heavy weight and require regular maintenance
[0003] In addition, during the application process, ordinary vacuum generators are difficult to control the vacuum degree due to unstable pumping volume, and the intermittent time of intermittent work is not accurate, resulting in inaccurate vacuum generator movements.

Embodiment Construction

[0016] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0017] Such as figure 1 The innovation of the vacuum generator shown is that the vacuum generator includes an exhaust port 1, a Laval nozzle 2, a nozzle 3, a negative pressure chamber 4, a vacuum port 5, a housing 6 and an air inlet 7;

[0018] The exhaust port 1, the nozzle 3, the negative pressure chamber 4, the Laval nozzle 2, and the air inlet 7 are sequentially arranged in the vacuum generator housing 6, and the Laval nozzle 2 and the exhaust port 1 are connected through the nozzle 3, A vacuum port 5 is installed in the vertical direction of the nozzle 3, the negative pressure chamber 4 is located at the interface between the Laval nozzle 2 and the nozzle 3, and the air inlet 7 is connected to one end of the Laval nozzle 2;

[0019] The casing 6 has a T-shaped structu...

Abstract

The invention relates to a vacuum generator which has the innovative points that the vacuum generator comprises an exhaust port, a Laval nozzle, a nozzle, a negative pressure cavity, a vacuum port, a shell and an air inlet; the vacuum generator uses compressed air as power; according to the vacuum generator, by enabling the compressed air to enter an airflow nozzle, airflow flows out of the nozzle at a high speed, a suction effect is generated, and finally, the compressed air and the sucked air are exhausted into the atmosphere through a receiver nozzle. The vacuum generator adopting the design is simple in structure, low in manufacturing cost, small in adsorption volume, short in response time, low in surface leakage rate and low in air consumption.
