Abstract

The utility model provides a self-air-sucking pulse water jet injection device, which relates to an injection device capable of ejecting water jets with good erosion effect under the condition of low water pressure, and can be applied to the fields of cleaning, erosion, sprinkling and the like. Under the existing technical conditions, water injected by injection devices for cleaning, eroding, sprinkling and the like requires high pressure. At present, tap water with low tap water pipe network pressure is utilized to be ejected in masses of cleaning, eroding, sprinkling operations, and the water pressure is limited by the pipe network pressure so that the erosion effect of the water jets ejected out of a spray nozzle or jet distance is limited. If other water pressurizing devices are adopted to improve the water pressure of the injection device, the investment is increased and other problems in use are caused. The self-air-sucking pulse water jet injection device does not need additional power, utilizes the energy of the water jets flowing into the injection device to enable the water jets flowing into the injection device to perform air suction and self-excitation oscillation, and changes low-pressure continuous water jets into air-mixed pulse water jets. Under the condition of constant water pressure, the eroding performance of the air-mixed pulse water jets is improved, the jet distance is far, the performances of the devices for cleaning, eroding and sprinkling are improved, and the application range of the devices for cleaning, eroding and sprinkling is widened.
