を目的とする。[Detailed Description of the Invention] The present invention relates to a small manual sprayer, and in particular, adjusts the area of the high-pressure liquid path leading to the nozzle hole of the spray head at the upper end of the stem to vary the pressure of the high-pressure liquid in this part.
An object of the present invention is to provide a small manual sprayer that can adjust the spread of spray liquid ejected from a nozzle hole.

押下げ自在の噴霧ヘツドである。 Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a mounting part that is removably attached to the container by screwing or other means, 2 an engagement tube extending upward from the attachment part 1, and 3 a locking part that does not slip out from the engagement tube 2. It is a depressable spray head that is inserted into and guided by it.

設けてある。 This type of sprayer is well known, so to briefly explain the main parts, excluding the main parts, the mounting part 1 is equipped with a vertically long cylinder that hangs downward. A riser pipe is installed vertically. On the other hand, the cylindrical piston that slides up and down within the cylinder has a stem 4 that penetrates through the engagement tube 2 and projects upward to communicate with the spray head 3.
The integral body of the stem 4, piston, and spray head 3 is always urged upward by a spring built into the cylinder, and a suction valve and a discharge valve are provided at the upper end of the suction pipe and the lower end of the stem, respectively. is provided.

作の1サイクルが終る。 With this structure, under normal conditions, the cylinder is filled with the liquid in the container sucked up through the suction pipe, and in this state, the spray head 3 pushes the piston downward against the spring through the stem 4. When lowered, the upper opening of the piston is sealed with a discharge valve, so the lowering action increases the hydraulic pressure inside the cylinder. When this hydraulic pressure reaches a predetermined value, the discharge valve is pushed up, causing the pressure inside the cylinder to increase. The liquid is sprayed outward from the nozzle hole 5 through the gap between the discharge valve and the stem 4 in the form of a mist. When the depressing operation is stopped when the liquid in the cylinder is almost jetted out, the spray head 3,
The stem 4 and the piston are returned to their original state by the spring, but on the other hand, when the liquid ejection ends, the inside of the cylinder becomes negative pressure, so the liquid in the container flows through the suction pipe,
It flows into the cylinder through the suction valve, completing one cycle of the spray operation.

させた場合を示している。 In the present invention, the spray head 3 has the following structure. That is, an inverted T-shaped through hole 8 having a large diameter at the bottom and a slightly smaller diameter at the top is formed in the center portion of the top wall 6 corresponding to the liquid path 7 of the stem 4.
A bowl-shaped elastic member 9 made of highly flexible rubber is arranged in the large diameter part of the stem 4, and the peripheral edge of the elastic member 9 is clamped and fixed between the downward step part 10 at the lower end of the small diameter and the upper end surface of the stem 4. The upper end opening of the stem 4 is sealed, and an adjustment shaft 12 that can be raised and lowered by a knob 11 is screwed into the small diameter part of the through hole 8. Note that 13 is a groove at the upper end of the stem 4, and the liquid path 7 of the stem 4 is connected to this groove 13.
It communicates with the nozzle hole 5 through a passage 14. The figure shows the case where the adjustment shaft 12 is fully lowered and comes into contact with the elastic member 9.
上記構成であれば、調整軸12を一杯に下降さ
せた図の実線位置では弾性部材9は調整軸12に
より上面を押えられているので液路7の高圧液で
押上げられても変位しないが、調整軸12を破線

で、ノズル孔5に導かれる高圧液の液圧がこの空
所Aにて変化し、従つてノズル孔5からの噴霧液
の勢いが変化するのでその広がりが調整できるこ
とになる。 With the above configuration, at the solid line position in the figure when the adjustment shaft 12 is fully lowered, the elastic member 9 will not be displaced even if it is pushed up by the high pressure liquid in the liquid path 7 because the upper surface is held down by the adjustment shaft 12. When the adjustment shaft 12 is pulled upward as shown by the broken line, the elastic member 9 during spraying is pushed upward by the high-pressure liquid and displaced as shown by the broken line, and the area of the space A at the upper end of the stem 4 increases. The pressure of the high-pressure liquid introduced into the nozzle hole 5 changes in this space A, and therefore the force of the sprayed liquid from the nozzle hole 5 changes, so that its spread can be adjusted.

る。 FIG. 2 shows another embodiment, in which the through hole 8
A piston 15 that can be raised and lowered is provided inside the interior, and this piston 15 is constantly pressed downward by an elastic member 9 made of a spring disposed between the lower surface of the adjustment shaft 12. By raising and lowering the adjustment shaft 12, the elastic member 9 is By varying the spring force, the pushing position of the piston 15 pushed up by high pressure fluid from the stem 4 fluid path 7 is varied, and the area of the space A is varied. You can achieve your goals as well.

3部分の改良ですむので製造上有利である。 In the present invention, the upper end opening of the stem 4 is sealed using an elastic member 9 that is displaced by high-pressure liquid, and the displacement of this elastic member 9 is adjusted with an adjustment shaft 12 to vary the area of the void A in this part. As a result, the spread of the spray liquid from the nozzle hole 5 can be adjusted to be wide or narrow at will, which is convenient for use. In addition, the operation is extremely simple, as the adjusting shaft 12 only needs to be raised and lowered by screwing with the knob 11. Further, in terms of structure, only the elastic member 9 and the adjustment shaft 12 are sufficient, and furthermore, the spray head 3 only needs to be improved, which is advantageous in manufacturing.
