Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Example 1

A water jet air ejector device is shown in figures 1-3 and comprises a base 1, a mixing cavity 2, a sealing plate 21, an air inlet connector 3, a first throat pipe 4, a high-pressure water pump 6, a water inlet connector 7 and a nozzle 8, wherein the mixing cavity 2 is arranged on the right side of the upper portion of the base 1, the first throat pipe 4 is fixedly connected to the right side of the mixing cavity 2, the high-pressure water pump 6 is bolted to the left side of the top of the base 1, the input end of the high-pressure water pump 6 is bolted to the water inlet connector 7, the sealing plate 21 is bolted to the mixing cavity 2 and the high-pressure water pump 6, so that the water jet air ejector device is convenient to detach, the nozzle 8 is bolted to the sealing plate 21, the bolted joint is sealed by adopting a rubber ring, a net-shaped inverted cone is arranged on the inner structure of the nozzle 8, the sealing plate 21 is bolted to the output end of the high-pressure water pump 6, the sealing plate 21 and the nozzle 8 are communicated, and the front side wall of the mixing cavity 2 is in a penetrating manner and is bolted to the air inlet connector 3.

As shown in fig. 2, the mixing chamber 2 further comprises a corrugated plate 5, the inner side wall of the mixing chamber 2 is provided with the corrugated plate 5, and the surface of the corrugated plate 5 is corrugated and convex.

When the device is needed to be used, one end of a water pipe is connected with a water inlet connector 7, the other end of the water pipe is connected with a water source, a high-pressure water pump 6 is started, the high-pressure water pump 6 pumps water from the water source, the water passes through the high-pressure water pump 6 and is ejected out of a nozzle 8 through an output end through a sealing plate 21, the water can be divided into a plurality of high-pressure water beams by an internal inverted cone in a hole of the nozzle 8, the water beams are ejected out of a mixing cavity 2 and a first throat pipe 4 at high speed at the moment, in the process, according to Bernoulli's theorem, the internal pressure is small due to the fact that the flow velocity of the internal water beams is too high, air enters the mixing cavity 2 from an air inlet connector 3 under the condition that the external pressure is larger than the internal pressure, the mixing cavity 2 is small, the large amount of air is prevented from being retained, a large amount of air is discharged out of the mixing cavity 2 and the first throat pipe 4 due to the fact that the air enters the mixing cavity 2 to generate air vortex, and the formed can be scattered by the protruding parts of corrugated plates 5 inside after the air enters the mixing cavity 2.

Example 2
