Description

Liquid spray

The present invention relates to a liquid injector, more specifically, it is coupled to the end of the hose is supplied with liquid can be easily modified and fixed the spraying of the liquid as well as the spraying state, in particular to prevent the twisting of the hose during use of the liquid injector An improved liquid spray machine is possible.

The liquid injector transforms the pressure energy into velocity energy by reducing the ejection cross-sectional area of the liquid supplied through the hose, thereby increasing the ejection distance of the liquid. Such liquid injectors can be classified into various types according to their purpose or application field, but a typical example that is commonly used in everyday life is a landscaping and car wash liquid called a so-called spray gun that is similar to a gun to facilitate the user's gripping and using. It is an injector.

1 is a cross-sectional view of a general landscaping and car wash liquid spraying machine (hereinafter simply referred to as a liquid spraying machine), which includes a main body 2 and a handle 6 provided with a lever 10, and the handle 6. The liquid supply hose (A) is connected to the end to inject the liquid in front of the main body (2).

To this end, the injection passage 4 is formed in the body 2 along the longitudinal direction, and the handle 6 branches from the outer surface of the main body 2 and is connected to the injection passage 4 therein. The supply path 8 is penetrated. In addition, the lever 12 is provided so that the center portion is connected to the outside of the handle 6 via the hinge 12 so that the seesaw movement is possible, and one end of the stamp valve 16 is elastically supported by the spring 14. 10) arranged in the injection passage 4 in a state connected to the upper end to open and close the injection passage 4 of the front end portion of the main body (2).

In addition, the hose A is connected to the inflow path 8 of the distal end of the handle 6, and when the user grips them together with the hand so that the lever 10 is pulled in the direction of the handle 6, the stamp nozzle 16 is connected. The jet path 4 is opened backward, and the liquid supplied from the hose A is jetted forward. On the other hand, if the hand is loosened so that the lever 10 and the handle 6 are separated from each other, the stamp nozzle 16 is advanced by the elasticity of the spring 14 to block the injection path 4, and the liquid supplied from the hose A Injection is stopped.

In this case, the head of the liquid injector 2 according to the purpose may be provided with a shower head 18 including a screen 20 through which a plurality of injection holes 22 are perforated, as shown. The liquid may be sprayed in the form of small streams of water or small droplets such as mist.

However, the above-mentioned general liquid injector exhibits some disadvantages in use. Firstly, during the use of the liquid injector, the hose A is frequently twisted and the smooth liquid spraying operation is frequently interrupted.

That is, in case of carrying out washing or garden water supply or water cleaning using the above-mentioned general liquid spraying machine, the user injects the liquid while changing its position or direction, which is fixed to the end of the handle 6. The hose A may be twisted, and if the degree is severe, the hose A may be blocked and the spraying of the liquid is impossible. Therefore, the user has a hassle to check whether the hose (A) is twisted at any time and to release it.

Secondly, the liquid injection direction is difficult to control due to the noise and vibration caused by the water hammer phenomenon during the use of the liquid injector.

More specifically, the water hammer phenomenon is a phenomenon in which a vortex is generated due to the pressure and the weight of the fluid when the fluid flowing through the pipe is sharply interrupted at a high pressure, hitting the cracking point strongly, and noise and strong vibration are generated. This water hammer phenomenon is the same when the stem nozzle 16 opens and closes the injection furnace 4, so noise and vibration are generated. This discomforts to the user, and at the same time, the spraying direction of the liquid injector is distorted. Spraying is often observed.

Thirdly, in the case of the liquid spraying machine with the shower head 18 attached, the liquid spraying type such as direct water or spraying is completely dependent on the spray hole 22 of the screen 20. There is a hassle to stop the injection of the liquid every time and replace the screen (20).

Finally, the above-mentioned general liquid spraying machine is limited to the user's movement because the user has to grab the lever 10 and the handle 6 by force to inject the liquid, and the liquid spraying time is long or the hydraulic pressure is increased. If it is high, there is a disadvantage that takes a lot of effort.

The present invention is to solve the above problems, it is possible to prevent the twist of the hose during use and to easily control the spraying form of the liquid, in particular to suppress the water hammer phenomenon and provide a liquid sprayer without inconvenience even for a long time use Its purpose is to.
