Backspreader {device for sprinkling water wearing on the back}

The present invention relates to an equalizer sprayer that allows workers to spray water on their backs. In particular, fire extinguishing workers can spray a container containing a predetermined volume of liquid in order to completely remove the residual fire during the fire extinguishing. It is designed to make a structure that prevents the movement of internal liquid from occurring due to the movement of the work in the mountainous areas and the leakage of the connected liquid by allowing the discharge of the stored liquid to escape through the uppermost part. This is to be prevented.

And the present invention is to configure the structure in which the liquid is injected into the container by the repetitive operation of the piston, so that the operator to attach the handle to the end of the piston to facilitate the gripping.

In the dry winter or early spring, wildfires are easily generated even in small embers, which causes considerable damage to human and physical property every year. The occurrence of forest fires causes a lot of changes in the surrounding topography, the possibility of landslides increases, and also affects the lives of the residents.

In particular, in the case of a windy winter season, a single forest fire damages a vast area of forests, and extinguishing is also difficult. When a large forest fire occurs, firefighting helicopters are used to perform the first firefighting work, but it is necessary to deal with the remaining fires in order to achieve complete firefighting. Indeed, wildfires are often generated by the remaining embers after the first evolution, and in order to remove such embers, a large number of workers must be put in and treated with water.

The prior art devised for this purpose was the attached fire spreader for the fire extinguishing of Fig. 1, as shown, which is a container (1) in which water is stored therein and a discharge pipe (2) on the lower side of the container (1). ) Forms a structure in which the piston is formed in the discharge pipe (2) is coupled to the injection mechanism (3) for injecting water in the container.

Conventional equalizer sprayer configured as described above is a natural leak occurs because the connection portion 4 of the container (1) and the discharge pipe (2) is formed at the bottom, the disadvantage of using a high-performance sealing material to prevent such leakage phenomenon There was a problem that the type of the piston also comes inconvenient to use.

That is, in the conventional method of spraying water, a piston is inserted at the rear of the cylinder, and a handle is formed at the outer end of the piston to repeatedly move the piston, and the cylinder is moved by holding the cylinder while holding the cylinder. The water inside is sprayed. If the structure as described above is inconvenient to operate the piston, there is a problem in that work efficiency is also reduced.

And, in the case of a general backpack sprinkler, the interior is just an empty space. In such a situation, the water stored in the interior is a lot of slack when it is necessary to carry a lot of the pack sprinkler, which may leak to the outside and is inconvenient to move. There are also problems that follow.

Therefore, the present invention devised to solve the above problems in forming an equal load sprayer used for forest fire extinguishing, to form a connection with the pipe on the top of the container body so that there is no leakage phenomenon and to operate the piston more easily. It aims to provide convenience in using it.

Another object of the present invention is to provide an equalizer sprinkler having a structure that can prevent a liquid such as water contained therein from moving during movement.
