Embodiment Construction

[0031] figure 1 It is an adjustable nozzle of the present invention, comprising: a nozzle body 1 , at least two baffles 2 , an elastic member 3 and an adjustment member 4 . Wherein, the nozzle body 1 has a nozzle chamber 11 that allows fluid to pass through and spray forward.

[0032] The flap 2 is hinged to the front end of the nozzle body 1 through a hinge shaft 53. In this embodiment, the rearmost end of the flap 2 is hinged to the nozzle body 1 through a hinge shaft 53, and the flap 2 can be directly hinged to the nozzle body 1, it can also be hinged on the parts fixed with the nozzle body 1. The preferred scheme will be introduced later. Each of the baffles 2 includes a first portion 21 extending outward and forward from its hinge with the nozzle body 1 , and a second portion 22 extending inward and forward from the front end of the first portion 21 . The baffle 2 can rotate around the hinge shaft 53 away from the axis of the nozzle body 1, that is, outward, and the ba...

Abstract

The invention discloses an adjustable spray nozzle which comprises a spray nozzle main body, at least two baffle plates, elastic pieces for applying external force onto the baffle plates and an adjusting piece arranged on the spray nozzle main body in a sleeving way. The adjustable spray nozzle has the benefits that the adjustable spray nozzle is provided with the two or more baffle plates, and the baffle plates can simultaneously rotate outwards or inwards under the action of the adjusting piece so as to realize the jet area and shape regulation; as the baffle plates are provided, the jet area is regulated by means of the rotation of the baffle plates, not the deformation of the baffle plate selves, so that the regulation within a larger range can be realized; the adjustable spray nozzle can be suitable for spray devices with various jet apertures.

Description

technical field [0001] The present invention relates to the field of liquid jetting. Specifically, it is an adjustable nozzle. Background technique [0002] Liquid injection devices are equipped with nozzles, and in many cases, it is necessary to change the area and shape of the injection surface of the nozzle. For example, in the field of fire protection, it is necessary to adjust the injection range of the fire extinguishing agent according to the range of the fire point. In the field of garden irrigation, it is usually necessary to adjust the area and shape of irrigation. Therefore, some nozzles are equipped with a structure that can adjust the shape of the spray surface. Generally, an integral baffle is installed on the nozzle, and the shape and area of ​​the spray surface are changed by applying an external force to the baffle to change the shape of the baffle. This type of nozzle can be applied to spraying devices with a smaller spray diameter, such as a spray gun w...
