Problems solved by technology

Nowadays, a large number of cleaning, flushing, and spraying operations use tap water with low pressure in the tap water pipe network to spray directly. Since the water pressure is limited by the pressure of the pipe network, the erosion effect or spray distance of the water jet sprayed from the nozzle is limited.
Using other water pressure equipment to increase the water pressure of the injection device will increase investment and other problems in use

Embodiment Construction

[0018] The present invention is further described in conjunction with example (accompanying drawing):

[0019] Such as figure 1 , a self-aspiration pulsed water jet injection device, which has a water inlet nozzle (1), an air suction hole (2), an air suction chamber (3), a throat pipe (4), an oscillation chamber (5), and a reflection cone body (6) and mixed flow tube (7). The nozzle (1), suction chamber (3), throat pipe (4), oscillation chamber (5) and mixed flow pipe (7) are in the order of nozzle (1) in the upstream direction and mixed flow pipe (7) in the downstream direction set up. The nozzle (1) extends to the downstream end of the suction cavity (3), and the nozzle (1) is facing the upstream end of the throat (4); the mixed flow pipe (7) is arranged at the center of the reflection cone (6), and the mixed flow pipe ( 7) Directly facing the downstream end of the throat (4); the throat (4) connects the suction chamber (3) with the oscillation chamber (5). An air suctio...

Abstract

The invention relates to an ejection device capable of ejecting water jet with good erosion effect under low water pressure situation, the self-suction pulse water jet ejection device can be used in the fields of washing, rinsing, spraying and the like. Under the condition of the prior art, the water ejected by the washing, rinsing, spraying and the like ejection device needs higher pressure; now a lot of washing, rinsing and spraying operation utilize tap water with low pressure from the tap water pipe network to direct eject, as the water pressure is limited by the pressure of the pipe network, the erosion effect of ejection distance of the water jet ejected through a nozzle is limited; if the water pressure of the ejection device is improved through adopting other pressure water equipment, the investment and other problems in use are increased. The self-suction pulse water jet ejection device does not need any other external power, the energy of the water jet flown in the ejecting device is utilized, the water jet entering the ejection device can perform self suction and self-excitation vibration, the low pressure continuous water jet is changed into aeration pulse water jet; the erosion capability of the aeration pulse water jet is improved under the condition that the water pressure is not improved, the ejection distance is farther, the performance of washing, rinsing, spraying equipment is improved, and the use range of the washing, rinsing and spraying equipment is enlarged.

Description

technical field [0001] The invention relates to a spraying device capable of spraying water jets with better erosion effect under the condition of low water pressure. The self-absorbing pulsed water jet spraying device can be applied to the fields of cleaning, scouring, spraying and the like. Background technique [0002] Under the existing technical conditions, the water sprayed by spraying devices such as cleaning, scouring, spraying, etc. needs to have relatively high pressure. Nowadays, a large number of cleaning, flushing and spraying operations use tap water with lower pressure in the tap water pipe network to spray directly. Since the water pressure is limited by the pressure of the pipe network, the erosion effect or spray distance of the water jet sprayed from the nozzle is limited. Adopting other water pressure equipment to improve the water pressure of the injection device will increase investment and other problems in use. In practical application, there is a ne...
