ところで一般に作業者が前記噴射ガンを操作するには、一方の手でノズル本体 に設けた握り部を把持するとともに他方の手でノズル本体に設けたグリップを把 持して該グリップを回転操作して直進噴射と拡散噴射とに切換えるようにしてい るので、グリップを把持している手の回転操作が必要となつて手の動きが大きく なるばかりでなくその操作がしにくくなり、特に狭隘な場所では操作がしづらい という操作上の課題があるばかりでなくグリップの位置では外見上直進噴射か拡 散噴射かの判別がしにくいという別の課題もある。 By the way, in general, an operator operates the spray gun by grasping the grip provided on the nozzle body with one hand and the grip provided on the nozzle body with the other hand and rotating the grip. Since it is designed to switch between straight injection and diffusion injection, it is necessary to rotate the hand holding the grip, which not only increases the movement of the hand but also makes it difficult to operate, especially in a narrow space. Not only is there an operational problem that it is difficult to operate, but there is another problem that it is difficult to distinguish between straight injection and spread injection at the grip position.
【０００４】 本考案はかかる実情に鑑みてなされたもので、噴射ガンの切換操作が極めて容 易であり、しかも直進噴射か拡散噴射かの噴射形態が一目でわかるようにして、 前記課題を解決できるようにした、新規な噴射ガンを提供することを目的とする ものである。The present invention has been made in view of the above circumstances, and the switching operation of the injection gun is extremely easy, and the injection mode of straight injection or diffusion injection can be seen at a glance to solve the above problems. The purpose is to provide a new injection gun that is made possible.

The opening 37 is opened. When a straight injection of a fluid such as cleaning water is desired, the operation handle 14 in the neutral position N is swung forward or backward, and the operation handle 14 is linearly tilted backward by about 45 °. The edge 15 2 of the lever mounting portion 15 engages with the outer surface of the nozzle body 1 so that the operation handle 14 is locked at the rear position, that is, the straight injection position R. As a result, the switching valve V also connects the first valve port 8 of the valve body 6 to the first inlet port 10 and the first outlet port 12 as shown in FIGS. Here, if the opening / closing lever 35 in front of the grip portion 3 is pulled to the front, the opening / closing valve 30 is opened, and fluid such as cleaning water flows from the hose 29 through the fluid supply passage 28 to the main fluid passage 27.

And the edge 15 1 of the mounting portion 15 is engaged with the outer surface of the nozzle body 1 to lock the operation handle 14 at the front position, that is, the diffusion injection position F. As a result, the second valve port 9 of the valve element 6 also communicates with the second inlet port 11 and the second outlet port 13 of the switching valve V as shown in FIG. 9. If the opening / closing lever 35 in front of the grip portion 3 is pulled toward you, the opening / closing valve 30 is opened, and fluid such as cleaning water flows from the hose 29 through the fluid supply passage 28 to the main fluid passage 27, and from here.

It is possible to perform straight injection and diffusion injection of the injection fluid such as.
