Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a manual sprayer that sprays liquid under pressure, and in particular to a nozzle device thereof.

(Prior Art) Generally, this type of atomizer is configured to spray a liquid under pressure in a mist or foam state from a liquid container.

Conventionally, such sprayers have been equipped with a wide variety of mechanisms,
In addition, it is well known to those skilled in the art that countless improvements have been proposed, and some of them are in practical use. For example, there are those configured to reduce the volume of a flexible liquid container against its elasticity, apply pressure to the liquid, and spray it from a spray hole, and those configured to use a pump mechanism to suck up liquid from the liquid container. Some are configured to apply pressure and spray from a spray hole. In addition, the former and the latter, especially the latter, include those that are configured to simply eject liquid from the ejection holes, and those that are equipped with - number of ejection holes and rotate when ejecting the liquid from the ejection holes. There are things that are configured to give.

(Problems to be Solved by the Invention) In a sprayer configured to simply eject liquid from one ejection hole, when ejecting liquid.

Severe liquid splashing. Therefore, taking the case of using liquid detergent as an example, there are many liquid detergents that contain acids and alkalis as their main ingredients, which can scatter and cause damage to the human eye.
If it gets into the nose or throat, it can hurt these areas and cause fever if it is excessive, and if it comes into contact with people's skin, it can cause rough skin and have a significant adverse effect on the human body. Furthermore, if the liquid is splashed and applied to objects other than those for which it was intended, they may be eroded by the liquid.

Furthermore, when the liquid is sprayed in the form of a mist, the coating density is high in the center of the area coated with the liquid and low in the periphery, resulting in severe uneven coating and the area being coated is unclear. It is difficult to efficiently apply the required amount to the required surface area, and when it is sprayed in the form of a foam, it is unlikely that the applied surface area will be unclear, unlike when it is sprayed in an n-shaped form. is applied in clusters in − places, and therefore,
In either case, not only is it extremely uneconomical, but when attempting to apply it relatively evenly over a relatively wide area, the application efficiency is extremely low and a great deal of labor is required.

On the other hand, in a sprayer which is provided with - number of ejection holes and is configured to give rotation to the liquid when it is ejected from the ejection holes, almost the same problem as described above is observed. Further, depending on the pressure and rotational force of the liquid, the configuration of the spin mechanism, etc., the coating density may be low in the center of the surface area coated with the liquid and high in the periphery.

Therefore, in consideration of the above-mentioned problems, it is preferable to use a sprayer that includes a plurality of ejection holes and a spin mechanism that rotates the liquid. However, in order to solve the problem,
It is technically very difficult to directly apply such a configuration to a conventional sprayer. That is, in the conventional sprayer, the spin mechanism is configured as one of the members of the sprayer main body, and the ejection hole is provided separately from the spin mechanism.

Moreover, each component of this type of atomizer is generally manufactured with precision, and even the slightest misalignment of the component in the solder can impair the intended function, or in some cases, cause it to be completely lost. It may also occur due to handling by the user. Therefore, in a conventional sprayer,
It is technically extremely difficult to provide multiple components of the spin mechanism, provide multiple ejection holes corresponding to these components, and align them perfectly so that the liquid is ejected evenly. It is difficult to This will be easily understood by those skilled in the art.

Therefore, an object of the present invention is to provide a manual sprayer that can solve this problem mainly by providing a plurality of spin mechanisms and a spout hole in a single component separate from the sprayer main body. There is a particular thing.

(Means for Solving the Problems) The present invention includes a sprayer body including a liquid pressurizing means and a discharge opening for the liquid, and a sprayer body formed separately from the main body and attached to the discharge opening; The nozzle cap further includes a spin mechanism that rotates the liquid pressurized by the pressurizing means, and a nozzle cap that includes a spouting hole for the liquid located in the center of the spin mechanism.

Furthermore, in one aspect of the present invention, the spin mechanism and the ejection hole include:
Each number consists of corresponding numbers.

Furthermore, the present invention includes an outer cap that is fitted to the nozzle cap, and the outer cap has a plurality of liquid outlet holes located in the center with a predetermined distance from the outlet holes. An air introduction hole communicating with the outlet hole is provided.

(Function) In the present invention, the liquid contained in the sprayer main body is pressurized inside the sprayer main body, and is rotated by the spin mechanism provided in the nozzle cap located at the outlet opening. .

It is ejected from the ejection hole located at the center of the spin mechanism. The ejected liquid is ejected to the outside through the liquid outlet hole of the outer cap located on the outside of the nozzle cap, but when ejected from the ejection hole, the air introduction hole communicates with the ejection hole. mixed with air drawn in from the

(Example) Further, the present invention will be explained based on the illustrated example.
It is as follows.

FIG. 1 shows an example of a manual sprayer to which the present invention is applied. This sprayer main body 1 is.

The trigger set includes a container 2 containing a liquid made of a desired component or a combination thereof, a body 3 connected to the upper end opening of the container and equipped with a pump mechanism (not shown) therein; Such a main body 1, which includes a piston 4 that is fitted into a cylinder constituting a mechanism so as to be able to move up and down, and a trigger 5 that operates the screw 1, is known to those skilled in the art, and the trigger 5 is When pulled, the piston 4 descends against the spring acting on it, and the liquid in the cylinder is put under pressure and is ejected through the piston 4 to the outside through a conduit connected to the piston. On the other hand, when the pull on the trigger 5 is released, the piston 4 rises under the action of the spring and enters the cylinder through a valve provided at the bottom of the cylinder. Then, the liquid in the container 2 is sucked up, and the trigger is returned to its original position, so that the liquid is ready to be spouted as described above. Incidentally, one aspect of the present invention, as will be clear from what will be described later, is an ejection hole and a spin mechanism attached to the outlet opening 7.

The present invention is directed to a nozzle device including a means for mixing the liquid and air from the ejection hole, regardless of the mechanism of the main body 1. Therefore, in the following, the nozzle device will be described.

1 to 6 show a nozzle device according to a first embodiment of the present invention. This nozzle device 8 basically consists of a nozzle cap 9 and an outer cap 10.

As shown in FIGS. 2, 3, and 5, the nozzle cap 9 is formed into a cylindrical body, and includes an outer cylinder 11, a partition wall 12 that radially crosses the outer cylinder, and a partition wall 12 that extends from the partition wall. an inner cylinder 14 extending and provided with a locking protrusion 13 on its inner peripheral surface; a small diameter cylinder 16 positioned within the inner cylinder and extending from the partition wall 11 and provided with a concave notch 15 on the opposite side; A locking protrusion 17 is provided on the inner periphery of one end of the cylinder 11.

In addition, the nozzle cap 9 has one liquid ejection hole 18 in each part of the partition wall 12 that is between the inner cylinder 14 and the small diameter cylinder 16 and faces each other through the small diameter cylinder, and has one liquid ejection hole 18 at the center of the injection hole. A spin mechanism 19 is provided on the outer periphery of the spindle. The spin mechanism 19 is as shown in FIG.

It consists of intermittent protrusions 21 that are elongated in the surface direction of the partition wall 12 and are arranged to surround one ejection hole 18 with each gap 20 interposed therebetween.

The thus configured nozzle cap 9 is fitted into the outlet opening 7, as shown in FIG. This mating state is
The lead-out opening 7 is inserted between the inner cylinder 14 and the small-diameter cylinder 16, and the locking protrusion 13 of the inner cylinder engages with a stepped shoulder 22 provided on the outer periphery of the lead-out opening, thereby retaining the lead-out opening 7. has been done.

In addition, in this fitted state, each concave notch 15 of the small diameter cylinder 16 and each concave notch 23 provided on the opposite side of the end face of the outlet opening 7 communicate with each other, and the concave notches 15° 23 A liquid flow path is formed by communicating with the ejection hole 18 via the spin mechanism 19 and the gap between the partition wall 12 and the end face of the outlet port 7 facing the partition wall 12 .

As shown in FIGS. 2 and 4, the outer cap 10 has an air introduction hole 24 located in the center, and an air introduction hole 24 located in the opposite side through the introduction hole, with one side expanding into a tapered shape. It has a lead-out hole 25 and a locking groove 26 on the outer periphery of one end.

The thus configured outer cap 10 is fitted into the nozzle cap 10, as shown in FIG. This fitted state is maintained by engagement between the locking groove 26 and the locking protrusion 17 of the nozzle cap 9. In this fitted state, the introduction hole 24 and the outlet hole 25 communicate with each other through the gap between the end surface of the outer cap 10 and the nozzle cap 9 and the partition wall 12 that oppose this, and the introduction hole and the outlet hole By communicating with the ejection hole 18 of the nozzle cap 9, a liquid flow path is formed.

7 and 8 show a nozzle device [10B] according to a second embodiment of the present invention. In this device 108, three ejection holes 118 and three spin mechanisms 19 each having the same structure as the ejection holes 18 and the spin mechanism 19 are provided at predetermined intervals. In addition, three liquid outlet holes 125 are provided at predetermined intervals in correspondence with these, and three elongated air introduction holes 124 are provided at the center of the outlet holes and cross-communicate with each other. ing. The rest of the configuration is essentially the same as the nozzle device 8, so a description thereof will be omitted.

In the first embodiment (the second embodiment is omitted) of the present invention having the above-described configuration, the liquid in the container 2 is sucked up and pressurized by the pump mechanism in the body 3, and the piston 4, It reaches the outlet opening 7 via the outlet pipe 6. Furthermore, this liquid flows from the outlet opening 7 to the concave notch Is, 23. It flows into the spin mechanism 19 from the gap 20 through the opposing gap between the end face of the lead-out opening 7 and the partition wall 12, where it is wound once and given rotation. This liquid is mixed with air that is sucked in through the introduction hole 24, passes through the opposing gap between the end surface of the outer cap 10 and the partition g112, and reaches the outlet hole 25, and is ejected to the outside. In this case, if the liquid contains a foaming component, it will be foamed by mixing with the air.

(Effects of the Invention) According to the present invention, as described above, since the nozzle cap and the spin mechanism are provided separately from the sprayer main body, a plurality of the nozzle holes and the spin mechanism are provided. Even if the spray holes and the components of the spin mechanisms are misaligned, there will be no defective products, and the sprayer can function as intended.

In addition, by providing a plurality of ejection holes and a spin mechanism, it is possible to eject and apply atomized or foamed liquid relatively evenly over a wide surface area onto a utensil or the like. Incidentally, this coating is possible because the applied areas from each nozzle overlap with each other in a shifted state, but the overlapping range mainly depends on the spacing, size, and angle of each nozzle. Since most of them are determined, it is only necessary to select them as necessary.

Furthermore, although the ejection holes and the spin mechanism are of various types, the outer cap attached to the nozzle cap has an air introduction hole communicating with the ejection hole and a liquid outlet hole communicating with the ejection hole. Since it is located at the center of the air intake hole, the necessary amount of air is sucked in from the air introduction hole and mixed sufficiently and evenly with the liquid spouted from the ejection hole. As a result, the product is homogeneous and foams well.

The present invention has such excellent effects and is extremely simple in structure, so it is extremely useful in practical use.
