Description

[Detailed Description of the Invention] The present invention relates to a sprayer for spraying liquid such as water.

2. Description of the Related Art Conventionally, hairdressing and beauty equipment conveniently used in beauty salons and the like have been known, and this hairdressing and beauty equipment is equipped with a sprayer for spraying liquid such as water, treatment liquid, cold liquid, etc. onto hair.

Conventionally, this type of atomizer has a structure that uses negative pressure generated by circulating compressed air to suck up the liquid stored in the bottle and turn it into a mist, but with this one, it is difficult to obtain a thin mist of liquid. However, the amount of spraying is small, it takes a long time to spray the liquid evenly onto the hair, and the liquid is in the form of a thin mist, so it is slow to penetrate the hair, making it impractical.

In particular, the above-mentioned drawbacks were noticeable in electric type compressors that used a compressor to obtain compressed air.

In view of the above-mentioned conventional circumstances, the present invention was developed by sending compressed air into a bottle in which liquid is stored, pushing out the liquid in the bottle, and ejecting it from a nozzle. To provide a sprayer which has advantages such as being able to obtain a large amount of liquid sprayed, spraying the liquid onto hair etc. in a short time, and shortening the time for permeation of the liquid.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Fig. 1 is a diagram showing beauty equipment, in which 1 is a wagon with casters 3 attached to each of its four legs 2;
Reference numeral 5 denotes a component storage section supported at the bottom of the wagon 1, in which a blower 4 for sucking air from the outside and a compressor 8 as a compressed air supply device for the sprayer according to the present invention are housed. Reference numeral 7 denotes an upper case body provided on the upper part of the wagon 1, with a flat placing part 9 in the center, and an operating part 10 with an inclined surface on one side and a bottle holder 11 for a sprayer, which will be described later, on the other side. has been done.

12 is a roll handle for drying hair, etc.

13 is a sprayer showing an example of the present invention. Such a sprayer is constructed as shown in FIG.

In the figure, 14 is a bottle in which liquid A such as water is stored, and has a bottle mouth-shaped opening 14A at the upper end. 15 is an upper end opening 14A of the bottle 14;
The bottle 15 can be freely attached and detached by fitting the female threaded part 15a provided on the inner periphery of the recess 15A at the lower end to the male threaded part 14a provided on the outer periphery of the opening 14A of the bottle 15. 16 is a ring-shaped packing interposed between the inner end surface of the recess 15A of the head 15 and the upper end surface of the opening 14A of the bottle 14, 17 is a nozzle member attached to the side end of the head 15, and 17A is a nozzle. It is. This nozzle member 17 is attached by fitting a male threaded portion 17a provided on the outer periphery into a female threaded portion 15b provided on the inner periphery of the recess 15B at the end on the side of the head 15. 1
Reference numeral 8 indicates a screw for adjusting the spray state that is screw-fitted and attached to the inner periphery of the nozzle member 17, and reference numeral 19 indicates a head 15.
A liquid feeding path that communicates the inner space of the recess 15B with the upper space of the bottle 14, and the upper end opening 2 of the 20 liquid feeding tubes is connected to the communication port 15C with the upper space of the bottle 14.
0A is plugged and connected. This liquid sending pipe 20
extends vertically downward within the bottle 14 from the connecting portion, and the lower end opening 20B is located near the inner bottom surface of the bottle 14 and opens into the liquid A. Reference numeral 21 indicates an air release hole that is provided to penetrate the head 15 from the upper end to the lower end and communicates the interior space of the bottle 14 with the outer space. The compressed air tube 23 is connected to the inner periphery of the communication port 15D, which is provided in communication with the compressed air tube 23, by a connector that is press-fitted in a freely attachable and detachable manner.

This compressed air tube 23 is connected to a compressed air pipe 24 connected to the compressor 8 shown in FIG. 1, and this connection is made through 25 connecting fittings supported on the upper case body 7 as shown in the same figure. .

In the atomizer having such a configuration, compressed air is introduced from the compressor 8 shown in FIG. Here, the air leak hole 2
When the upper end opening 21A of 1 is closed with a finger or the like, compressed air is supplied into the bottle 14, and the liquid A is passed through the liquid sending pipe 20.
Push it inward. The pushed out liquid flows from inside the liquid feeding pipe 20 through the liquid feeding path 19 and the recess 15B to the nozzle member 1.
A mist is ejected from the nozzle 17A of No. 7. When the finger or the like blocking the upper end opening 21A of the air vent hole 21 is removed, the compressed air escapes from the air vent hole 21 to the outside and is no longer sprayed.

According to the above configuration, by pushing out the liquid with compressed air and atomizing it, the liquid becomes a rough mist with a large amount of spray (approximately 10 to 20 times as much as conventional methods). Liquids and the like can be sprayed onto hair in a short period of time, and since the liquid is in the form of a rough mist, the time for these liquids to penetrate into the hair is quick, allowing various hairdressing and beauty treatments to be performed quickly. Further, since the nozzle member 17 is directly connected to the bottle 14 and the bottle 14 and the compressed air pipe 24 on the compressor 8 side are connected via the compressed air tube 23, the nozzle member 17 and the bottle 14 are connected to each other via a tube or the like. Since there is no need to connect the tubes with each other and the number of tubes can be reduced, it is superior in terms of production and cost, and since the nozzle member 17 can be operated by directly holding the bottle 14, it is also excellent in usability. Furthermore, an air vent hole 21 is provided that communicates the interior space of the bottle 14 with the exterior space, and the spray state and release state can be selected by opening and closing this hole with a finger or the like. There is no need to use special means to control the supply of compressed air to the interior space of the bottle 14, and the configuration is simplified and operability can be improved because it can be operated with a finger or the like.

Next, in the embodiment of the present invention, the liquid feeding path 19 that communicates between the nozzle 17A and the area below the liquid surface in the bottle 14 is communicated with the space inside the bottle through an air introduction hole whose cross-sectional area can be adjusted. Do it like this.

That is, the air introduction hole is as shown in 26 in the figure.
An adjusting screw 27 is provided to open in the recess 15A of the head 15 and the inner circumferential wall of the liquid feeding path 19, and adjusts the cross-sectional area of the air introduction hole 26.

This adjustment screw 27 is screwed in from the side end wall of the head 15 so as to cross the air introduction hole 26, and by changing the screw fitting position, the air introduction hole 26 can be adjusted.
The cross-sectional area of the passage can be adjusted.

Therefore, by adjusting the adjustment screw 27 to introduce a large amount of compressed air in the bottle 14 into the liquid feeding path 19 and mixing it with the liquid, the liquid to be ejected from the nozzle 17A can be ejected in the form of small atomized particles. If a small amount of compressed air is introduced into the liquid feeding path 19, the liquid can be sprayed in large spray particles, and the liquid can be used in an optimal spray state according to various beauty treatments.

Note that when using the above-mentioned spray particle adjusting device, if the amount of compressed air mixed in from the air introduction hole 26 is too large, there is a risk that the liquid will not be ejected, so it is necessary to adjust the amount of air so that it is not too large.

As explained above, according to the present invention, the liquid stored in the bottle is sprayed by being forced out to the nozzle by the compressed air introduced into the bottle, and the liquid is sprayed in a rough mist state with a large amount of spray. Since it is sprayed, it is possible to spray the object that requires spraying in a short time, and the liquid can quickly penetrate into the object, which has great practical effects such as quick work and high efficiency. It is what it is. In particular, according to the present invention, the bottle and the spray nozzle are connected, and the tubes are connected between the bottle and the compressed air pipe on the compressed air supply device side, so the number of tubes can be reduced, improving productivity and cost. It has excellent properties and is also easy to use. In addition, an air vent is provided to communicate the inside space of the bottle with the outside air, and the presence or absence of spraying can be selected by opening and closing it with a finger, which has the advantage of simplifying the configuration and improving operability. .
