Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically to a pneumatically controlled anti-drip nozzle. Background Technology

[0002] In the agricultural sector, the rise of large-scale planting has prompted agricultural irrigation sprinklers to develop towards high efficiency and water conservation. For sprinklers, attention has begun to be paid to the spraying range and the uniformity of water distribution.

[0003] Traditional sprinklers often continue to drip water after spraying stops due to gravity. In agricultural irrigation, this can lead to excessive moisture in localized areas, affecting crop root growth and even causing diseases. In industrial production, such as in the spray cleaning process in electronic chip manufacturing workshops, the dripping water droplets may damage delicate electronic components. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatically controlled anti-drip nozzle that prevents water from dripping from the nozzle, thus solving the problem that the nozzle often continues to drip water after it stops spraying due to gravity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatically controlled anti-drip nozzle, comprising a connecting mechanism, the connecting mechanism comprising a circular tube, one end of which is provided with a circular ring, and the end of the outer edge of the circular ring away from the circular tube is provided with a nozzle mechanism, two second threaded grooves are symmetrically opened on the side of the circular tube, both of the two second threaded grooves are connected to the interior of the circular tube, and an air inlet mechanism and a liquid inlet mechanism are respectively spirally connected in the two second threaded grooves, the nozzle mechanism comprising a pressure tube, the pressure tube being embedded in the circular ring, and the end of the pressure tube away from the circular tube being provided with a liquid spraying pipe, the outer edges of the pressure tube and the liquid spraying pipe being connected together with a limiting nut sleeved on the outer edge of the circular ring.

[0006] Preferably, the outer edge of the ring away from the circular tube is provided with a first threaded groove that is helically connected to the limiting nut, and the ring is provided with a limiting step that abuts against the pressurizing tube inside the ring.

[0007] Preferably, a limiting plate is provided on the side of the pressurized tube away from the circular tube, and the pressurized tube is in contact with the inner edge of the circular ring, wherein the diameter of the limiting plate is smaller than the diameter of the circular ring.

[0008] Preferably, a limiting post is provided on the side of the limiting plate away from the pressurizing pipe, a sealing ring is sleeved on the outer edge of the pressurizing pipe to abut against the limiting step, a tapered tube is provided on the side of the limiting post away from the limiting plate, and a short tube is provided in the middle of the end of the tapered tube away from the limiting post.

[0009] Preferably, the spray pipe has a conical groove on the side near the pressurizing pipe and a conical protrusion on the side away from the pressurizing pipe. A spray head is provided in the middle of the end of the spray pipe away from the pressurizing pipe. A transverse groove is provided inside the spray head, which connects to the inside of the spray pipe and runs through the entire spray head.

[0010] Preferably, the air intake mechanism includes an air intake threaded pipe that spirally extends into the second threaded groove, and a first connecting nut is provided at the end of the air intake threaded pipe away from the round tube.

[0011] Preferably, the liquid inlet mechanism includes a liquid inlet threaded tube that spirally extends into the second threaded groove, and a second connecting nut is provided at the end of the liquid inlet threaded tube away from the round tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a circular tube, a second threaded groove, a pressurizing tube, a limiting plate, a conical tube, a short tube, a spray pipe, a spray head, an air intake mechanism, and a liquid inlet mechanism. The liquid inlet mechanism delivers liquid into the circular tube, while the air intake mechanism delivers gas. The pressurizing tube delivers liquid, and the reduced inner diameter of the short tube at the end of the conical tube alters the pressure, giving the liquid strong propulsion. The spray head, located on the spray pipe, atomizes the water into a fan shape through a transverse groove. Air pressure controls the opening and closing of the water flow channels inside the spray head. When the air pressure is normal, the water flows smoothly; when the air pressure disappears or decreases, the channels quickly close, effectively preventing dripping. Compared to other anti-drip technologies, the air-controlled method is more sensitive and can more accurately control the start and stop of the spray, meeting the needs of industries with high spray control precision.
