Embodiment Construction

[0037] figure 1 It is a schematic cross-sectional view of a nozzle with adjustable spray area according to an embodiment of the present invention. like figure 1 As shown, the nozzle with adjustable spray area of ​​the present invention includes a nozzle body 1, at least two baffles 2, an elastic member 3 for exerting external force on the baffles 2, an outer adjustment member 4 sleeved on the nozzle body 1, and an inner adjustment Piece 5.

[0038] The nozzle body 1 has a nozzle cavity 11 that allows fluid to pass through and to be ejected forward. The blocking piece 2 is hinged with the front end of the nozzle body 1 through the hinge shaft 63. In this embodiment, the rear end of the blocking piece 2 is hinged with the nozzle body 1 through the hinge shaft 63, and the blocking piece 2 can be directly hinged on the nozzle body. 1, it can also be hinged on the part fixed with the nozzle body 1. The preferred solution will be described later. Each of the baffles 2 includes ...

Abstract

The invention discloses a spray nozzle with a spray area adjusting function. The spray nozzle comprises a spray nozzle body, at least two baffle sheets, an elastic element, an outer adjusting element and an inner adjusting element, wherein the elastic element applies external force on the baffle sheets, and the outer adjusting element and the inner adjusting element sleeve the spray nozzle body. The spray nozzle with the spray area adjusting function is provided with two or more than two baffle sheets, a plurality of baffle sheets can outwards rotate or inwards rotate at the same time under the effect of the outer adjusting element and the inner adjusting element, the adjustment on the spray area and shape is realized, the baffle sheets are multiple, and the spray area is adjusted through the rotation action of the baffle sheets instead of the deformation of the baffle sheets per se, so the wider-range adjustment can be realized, and the spray nozzle can be applicable to spray devices with various spray calibers.

Description

technical field [0001] The present invention relates to the field of liquid jetting. Specifically, it is a nozzle with adjustable spray area. Background technique [0002] Liquid injection devices are equipped with nozzles. In many occasions, the area and shape of the injection surface of the nozzles need to be adjusted. For example, in the field of fire protection, the injection range of the fire extinguishing agent needs to be adjusted according to the range of the ignition point. In the field of garden irrigation, it is often necessary to adjust the area and shape of irrigation. Therefore, some nozzles are provided with a structure that can adjust the shape of the ejection surface. Generally, an integral baffle is installed on the nozzle, and the shape and area of ​​the ejection surface can be changed by applying an external force to the baffle to change the shape of the baffle. This nozzle can be used on spray devices with smaller spray calibers, such as spray guns wit...
