Description

Portable Sprayer {Barrel of Sprayer for Portable}

The present invention relates to a portable spray bottle, more specifically, can be shouldered to be seated on the back in a convenient state to operate the pumping lever irrespective of the operator, convenient to change the position of the suspenders and integrated by fusing and fixing the body formed by dividing into two It relates to a portable spray bottle.

In general, in order to evenly spray a liquid such as water, medicine, pesticides, etc. to various crops, various kinds of sprayers are used depending on the operation method and the scale of the crop.

In order to spray the liquid on a relatively small crop of the above-mentioned sprayer, a portable sprayer (or a shoulder-type sprayer) that uses a suspender to carry the liquid to the shoulder and sprays the liquid is used a lot.

The portable nebulizer forms a container in which the liquid is stored in a width and a length corresponding to the back of the worker so that the operator can easily carry it on his back.

The portable spray cylinder is made of a synthetic resin and the body manufactured by blow molding, and the bottom material is installed separately on the lower end of the body, one side forming the width of the body is formed in the shape corresponding to the back seat do.

That is, when the body of the portable sprayer is formed by blow molding, the trace of cutting out the bottom of the parison (parison) remains on the bottom of the body so that the flat surface is not formed and does not stand in place. If the body is blow molded by hand, the bottom surface is rounded off by blow pressure and the stability is lost. Therefore, the conventional portable spray bottle is integrated by fixing the flooring material having a flat bottom at the lower end of the body made of blow molding by using an adhesive or the like.

When the back seat portion is formed in a shape corresponding to the back of the worker, one side of the body is seated on the back of the worker when the user is carrying it on his or her shoulder.

When the conventional portable spray bottle configured as described above forms the back seating portion on one side of the body, the pumping lever is installed only on one side, so that one operator of the right handed and the left handed cannot use.

And because the suspender fixture is fixed through the coupling bolt, etc., the damage is applied, and the fixed part is likely to be vulnerable due to the concentrated stress when the worker carries it.

Conventional portable spray bottle is configured as described above is frequently blown off as the adhesive portion of the flooring is lowered as the adhesive portion of the flooring material is manufactured by blow molding. In other words, the adhesive part bonded using the adhesive or the like changes the properties of the adhesive due to the change in temperature, the inflow of chemicals (pesticides, etc.), and thus the adhesive force is lowered and the body and the flooring material are separated, and the flooring material is separated from the body. Spraying is impossible because it is not reliably built on the ground.

In addition, in the conventional portable spray bottle, the bottom of the body formed by cutting off the bottom of the parison may be broken when the joint portion is operated by a high pressure inside the body. In other words, when the bottom of the parison is insufficiently bonded in the process of forming the body by blow molding, if a high pressure is applied to the inside of the body, there is a risk of being easily broken by the pressure.

An object of the present invention is to solve the problems as described above, by forming a back seat portion in the front and rear portion can be carried in a convenient state to operate the pumping lever according to the operator, one end of the suspenders conveniently It is to provide a portable spray bottle capable of being fixed and detached.
