Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nozzle, and particularly to a nozzle for an atomizer that sprays a liquid such as medicine or water in the form of a mist.

2. Description of the Related Art Sprayers have conventionally been used to spray insecticides on flowers such as flower beds and to spray water in the form of a mist onto the leaves of ornamental plants.

In this case, it is difficult to obtain a uniform mist using a manual sprayer, which sprays mist each time the pump is pressed, and it requires a lot of effort to spray over a wide area. Therefore, semi-automatic sprayers are widely used, which operate the pump several times in advance to sufficiently increase the pressure inside the container, and then open the spray port to spray continuously.

Most of the conventional sprayers mentioned above employ a cock to open and close the spray nozzle.

Due to the structure of the cock, the main choice is between opening and closing, and fine adjustment between the two is difficult, and the lever of the cock protrudes, making it easy to open or close while working. The disadvantage is that the direction of the liquid changes, and the amount of liquid that reaches the spray nozzle changes accordingly, resulting in a change in the spray state.

The present invention was developed in consideration of the above reasons, and by adopting a screw-type screw structure for the nozzle, it is extremely easy to make fine adjustments between the two when opening and closing the spray nozzle. It is possible to select any spray state steplessly by using the nozzle, and even if the nozzle inadvertently comes into contact with surrounding objects during operation, the opening/closing structure is not affected in any way. A nozzle for a sprayer is provided.

Hereinafter, this embodiment will be described in detail with reference to the accompanying drawings.

One embodiment of the present invention is explained in the figure, and the whole number is 1.
The one shown by is a sprayer, which is equipped with an air sending pump 3 having a handle 2 at one end, and the air sent from this pump 3 increases the air pressure in the container 4, and the water is contained in the container 4 from the water injection part 5. The liquid is injected from the nozzle 7 via the vibro.

The nozzle indicated by the reference numeral 7 as a whole is a nozzle according to the present invention, which is constructed based on a hollow cylinder 8.
The proximal end side of is welded and fixed to the shoulder of the container 4.

A flange 9 is formed near the base end of this cylinder 8 in contact with the container 4, and in front of this flange 9, that is, on the opposite side from the base end, is a body 10 having the same outer diameter as the base end. continuation,
A groove 1 is formed on this body 10 at a predetermined distance from the flange.
1 is bored, and in front of this groove 11 is a male threaded part 12.
is formed.

Reference numeral 13 indicates an annular packing, which is fitted and fixed in the groove 11 of the body portion 8.

Reference numeral 14 indicates a disc-shaped packing, the diameter of which is larger than the inner diameter of the cylinder 8, and a through hole 14a is bored in its center. The water stopper shown has a projection 15a formed in the center of one side of a flat disk 15b, the outer diameter of this projection 15a is approximately equal to the through hole 14a of the packing 14, and its length is It is much larger than the thickness of the gasket 14, and furthermore, two grooves 16 are formed on the circumferential surface of the disc 15b of this water stopper piece 15 with a phase shift of 180° from one edge to the other edge. It is drilled diagonally.

The diameter of the disc 15b of this water stop piece 15 is the diameter of the seal 1.
4, and when the protrusion 15a of the water stopper 15 is inserted into the through hole 14a of the seal 14, the groove 16 bored on the circumferential surface of the disc 15b of the water stopper 15 is It is located outward from the edge of the packing 14.

Further, what is indicated by the reference numeral 17 is a cap, and one end thereof has a large diameter having an outer diameter approximately equal to the outer diameter of the flange 9 of the cylinder 8 and an inner diameter larger than the outer diameter of the body portion 10. A portion 18 is formed, and a small diameter portion 19 is formed continuously to this large diameter portion 18, and this small diameter portion 19 is closed by a disk 20 having an arcuate cross section. A spray nozzle 21 is formed in a funnel shape with a small diameter on the inside and a large diameter on the outside.

Furthermore, a female thread 22 is formed inside the cap 17 from the inner end of the large diameter part 18 to near the tip of the small diameter part 19, and is threaded into the male thread 12.

A space 20a is formed between this female thread 22 and the disk 20 at the tip, and the inner diameter of this space 20a is approximately equal to the outer diameter of the disk 15b of the water stopper piece 15, and its thickness is It is larger than the thickness of the water stop piece 15.

Next, the fitted state of this embodiment and its usage will be explained.

First, the annular groove 1 of the cylinder 8 is welded and fixed to the shoulder of the container 4.
An annular packing 13 is fitted and fixed to 1.

Next, a disc-shaped gasket 1 is attached to the protrusion 15a of the water stop piece 15.
4 through the through hole 14a, and the water stopper 1 is fixed.
5 into the space 2Oa at the tip of the cap 17.

In this state, a spherical space is created between the water stop piece 15 and the disc 20.

Then, the cap 17 is fitted onto the body 8, and the female and male screws of both are screwed together.

Further, in the container 4, one end of a hollow water supply vibro is connected to the base end side of the nozzle 7, and the other end of this water supply vibro is led to the vicinity of the bottom surface of the container 4.

A liquid such as water or a drug is injected into the container 4 of the sprayer 1 configured as described above from the injection part 5 at the top thereof, and the cap 17 of the nozzle 7 is sufficiently tightened.

Then, as shown in FIG.
Since the space between the container 4 and the cylinder 8 is sealed, it is reliably prevented that outside air enters the container 4 through the nozzle 7 and that the gas and liquid in the container 4 are prevented from flowing out.

In this state, the handle 2 of the pump 3 is piston-moved several times to send a predetermined amount of air into the container 4.
Increase the internal pressure.

When the cap 17 is rotated and loosened, the disc-shaped gasket 14 separates from the tip of the cylinder 8 as shown in FIG. The spherical space at the tip inside the cap is filled through the groove 16 on the circumferential surface of the disc 15b, and then the spray nozzle 21
Spouts out in a mist form.

In this case, by adjusting the screwing state between the cap 17 and the cylinder 8, particles can be produced from extremely small particles to those close to water droplets.
Any spray state can be selected steplessly.

Even if the nozzle 7 accidentally comes into contact with surrounding objects during use, the screws will not tighten or loosen, so you can spray almost the same mist from beginning to end. can.

After use, just rotate the cap 17 to loosen it sufficiently and let the air out.

As is clear from the above explanation, according to the present invention, it is possible to select any spray state steplessly from extremely small particles to a state close to water droplets, and furthermore, the nozzle hits the surrounding objects during operation. A nozzle for an atomizer can be obtained which has an excellent structure in which the spray state is not changed even if the nozzle comes in contact with the nozzle, and which is cheaper than conventional ones.
