Embodiment Construction

[0024] Please refer to figure 1 and figure 2 , a telescopic spray gun of the present invention includes a sleeve 10, a spray head 20 that can reciprocate axially in the sleeve, and an elastic member 30 that applies elastic force to the spray head so that the spray head moves backward and retracts into the sleeve. A water cavity is arranged inside the spray head 20 , and a water outlet hole 22 is arranged on the side wall of the front part of the spray head 20 . Under normal circumstances, the elastic force of the elastic member 30 pushes the spray head 20 into the casing 10 to hide the spray head 20 so that the water outlet hole 22 is covered by the casing 10 to avoid being soiled. When in use, water enters the water cavity of the nozzle 20 and pushes the nozzle 20 to overcome the elastic force of the elastic member 30 to move forward and extend out of the casing 20 , and the outlet hole 22 extends out of the casing along with the nozzle 20 . Preferably, when the water pres...

Abstract

The invention discloses a telescopic spray gun comprising a sleeve and further comprising a spray head and an elastic part. The spray head is arranged in the sleeve in a mode that the spray head can reciprocate in the axial direction. The elastic part applies elastic force to the spray head, so that the spray head moves backwards and contracts into the sleeve. A water cavity is arranged in the spray head. The side wall of the front portion of the spray head is provided with a water outlet. During use, water enters the water cavity and pushes the spray head to overcome the elastic force of the elastic part, to move forwards and to extend out of the sleeve, and the water is sprayed out from the water outlet. Under the state without water, the elastic part presses the spray head into the sleeve, and the water outlet is hidden. During use, water enters the spray head, the water pressure acts on the spray head and pushes the spray head to overcome the elastic force of the elastic part, to move forwards and to extend out of the sleeve, the water outlet extends outwards, and water goes out. According to the telescopic spray gun, the elastic part is matched with the water pressure to conduct automatic stretching and contracting on the spray head, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to a telescopic spray gun, in particular to an automatic telescopic spray gun. Background technique [0002] Most of the traditional spray guns are monolithic structures, and the water outlet holes are exposed on the outer surface of the spray gun. When the gun is not used for a long time, the dust is easy to crawl all over the water outlet holes, which is unhygienic. For this reason, someone has designed a retractable spray gun, that is, the water outlet hole can be retracted into the inside of the spray gun when not in use, and stretches out again during use. However, the existing telescopic spray gun needs to be equipped with multiple casings, which are connected by a thread mechanism to match the edges, and the water outlet is arranged on the inner casing. Complicated and very cumbersome to do manually. Contents of the invention [0003] The invention provides a telescopic spray gun with simple structure and convenient use...
