Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a trigger type liquid ejector.
[0002]
[Prior art]
Trigger type liquid ejectors are widely used in general, and those that eject liquid as a water gun by changing the nozzle part depending on the application, those that rotate the ejected liquid as a mist by rotating at high speed, and further when atomizing However, in all cases, the liquid ejection holes, that is, the nozzle holes are singular.
[0003]
[Problems to be solved by the invention]
For example, in the case of a liquid for detergent, the liquid is often ejected in the form of a water gun, but in this way, since the ejected liquid is sprayed to one place, the liquid to be sprayed is adhered to wipe the wall surface etc. In this case, it is difficult to sufficiently spread the attached liquid, but the liquid sprayed portion is sufficient, but the attached liquid tends to be deficient in the peripheral portion outside the sprayed portion. In such a case, it is sufficient to atomize the liquid and spray it over a wide range, but in order to atomize the liquid, it is necessary that the liquid viscosity is relatively low. It is difficult to make it.
[0004]
The present invention is mainly provided so as to eliminate the above-mentioned drawbacks, and by providing a plurality of nozzle holes, it is possible to spray liquid at a plurality of locations at the same time by a single jetting operation, and to spray the liquid without waste. It is a thing. In addition, although the said dispersion spray demonstrated only about the case where a liquid is ejected as it is, it is applicable also in the case of fog or bubble discharge | release.

The palate-shaped part 33 is shaped. The palate-like portion projects rearward from the outer periphery of the front wall 33a through the peripheral wall 33b, and has a nozzle hole 34 formed at the center of each front wall. In the illustrated example, a known spin mechanism 35 for rotating the jetted liquid at a high speed is provided on the rear surface of the front wall as shown in FIG. 5, and the second through hole is provided via the third vertical groove 30 and the spin mechanism 35 described above. 25 and the nozzle hole 34 communicate with each other, and the high-pressure liquid that has entered the space between the first front plate 22 and the second front plate 32 through the second through hole 25 passes through the third vertical groove 30 to be spin mechanism. It enters the inside 35 and rotates at a high speed, and then mists are ejected from the nozzle hole 34. The spin mechanism is for atomizing the ejected liquid. Therefore, when the liquid is ejected in a water gun shape without being atomized, the spin mechanism is not necessary. The third vertical groove 30 may be provided on the inner surface of the peripheral wall 33b of the palate-like portion 33, and the spin mechanism may be provided on the front surface of the front fitting column 29.
[0017]
Reference numeral 41 denotes a multi-cylinder member, which is formed by penetrating a plurality of discharge cylinders 43 in the connecting plate 42. The number of discharge cylinders is the same as the number of the nozzle holes 34, and has a cylinder hole having a larger inner diameter than the nozzle holes and opening both front and rear end faces. The multi-cylinder member 41 is fitted to the inner surface of the front portion of the nozzle cap main body front outer cylinder 28 described above, but the member is provided with a fitting peripheral wall so that the peripheral wall is fitted to the outer surface of the nozzle cap main body front portion. Alternatively, the multi-cylinder member is attached to the front part of the nozzle cap main body via a hinge, and the multi-cylinder member is rotated around the hinge so that it can be attached to and detached from the front part of the nozzle member 21b. You can also. As shown in FIG. 3, the discharge cylinders 43 are inclined, and the rear end of the central axis of the discharge cylinder is positioned on the front extension line of the central axis of each nozzle hole, and the interval between the central axes of the discharge cylinders. Is provided so as to gradually expand on a front extension line of the central axis.
[0018]
In the illustrated example, an outside air inflow path 44 is opened between the nozzle member 21b and the multi-cylinder member 41 so that a large amount of outside air can be supplied to the mist ejected from the nozzle hole 34. It is possible to change the mist into bubbles by supplying such outside air. In the illustrated example, a third through hole 45 as an inlet of the outside air inflow passage is formed in the connecting plate 42 as shown in FIG.
[0019]
