Description
【考案の詳細な説明】 本案は泡沫噴出ヘッドに係るものである。[Detailed explanation of the idea] This proposal relates to a foam jetting head.
従来、この種のものは、空気と液体とを共にスポンジや
網等に通すことにより泡化している。Conventionally, this type of foam is created by passing air and liquid together through a sponge, net, or the like.
本案はこのようなスポンジや網等を全く用いないで液体
を泡化しようとするものである。The present invention attempts to foam a liquid without using such sponges or nets at all.
以下、図示の実施例について説明する。The illustrated embodiment will be described below.
第１図はその一例を示すものであり、第１図に於いて１
は液体を霧化噴出するヘッド本体、２はヘッド本体の前
方に設ゆられたテーパー状に次第に小さくなる噴出路、
３，３は噴出路の後端部側面に設けられた外気の通気路
である。Figure 1 shows an example.
2 is a head main body that atomizes and ejects liquid; 2 is a tapered ejection path that gradually becomes smaller in size in front of the head main body;
Reference numerals 3 and 3 designate an outside air ventilation path provided on the side surface of the rear end of the ejection path.
ヘッド本体１は、前端開口の筒体４の前端に小キャップ
体５を嵌通し、該小キャップ体は中央に噴射ノズル６を
有しており、筒体４内には小キャップ体内面に接して中
子７を有している。The head body 1 has a small cap body 5 fitted into the front end of a cylindrical body 4 with an open front end, and the small cap body has an injection nozzle 6 in the center. It has a core 7.
該中子７は前面即ち小キャンプ体に面してその噴射ノズ
ル６に通じかつ噴射ノズル６を中心とする渦流発生溝８
を有しており、側部に筒体４内部空間から渦流発生溝に
通じる液体の流通路９を有している。The core 7 has a vortex generation groove 8 facing the front surface, that is, facing the small camp body, communicating with the injection nozzle 6 and having the injection nozzle 6 as the center.
It has a liquid flow path 9 on the side that communicates from the internal space of the cylinder 4 to the swirl generation groove.
筒体４内の後部は弁座１０になっており、その弁孔１１
は後方のパイプ１２に通じている。The rear part inside the cylinder body 4 is a valve seat 10, and its valve hole 11
is connected to the pipe 12 at the rear.
但し、図示のものは筒体４とパイプ１２が一体に形成さ
れている。However, in the illustrated one, the cylindrical body 4 and the pipe 12 are integrally formed.
弁座１０には弁体１３が圧接閉塞させてあり、該弁体１
３には背面に弾性環１４が一体に設けられ、また、弾性
環１４は上記中子７の後面に一体に連設されて、該弾性
環１４０弾力で弁体１３は上記のように弁座に圧接され
ている。A valve body 13 is pressed and closed on the valve seat 10, and the valve body 1
3 is integrally provided with an elastic ring 14 on the back surface, and the elastic ring 14 is integrally connected to the rear surface of the core 7, so that the elastic ring 140 is elastic and the valve body 13 is pressed against the valve seat as described above. is pressed against.
従って、中子Ｉと、弁体１３と、弾性環１４は一体であ
り、適宜に弾力を有する合或樹脂或いはゴム等で形成さ
れている。Therefore, the core I, the valve body 13, and the elastic ring 14 are integral and are made of appropriately elastic resin, rubber, or the like.
そこで、パイプ１２から加圧液体がくると、その圧力で
弁体１３が開き、加圧液体は筒体４内に流入し、さらに
、中子の流通路９を通って渦流発生溝８に入って、ここ
で高速回転して渦流となり、噴射ノズル６より霧となっ
て噴出する。Therefore, when the pressurized liquid comes from the pipe 12, the pressure opens the valve body 13, and the pressurized liquid flows into the cylinder body 4, and then enters the vortex generation groove 8 through the flow passage 9 of the core. Here, it rotates at high speed to form a vortex, which is ejected from the injection nozzle 6 as mist.
つまり、高速渦流で噴射ノズル６から噴出すると液体が
微粒子に分散されるから、霧化されるのである。In other words, when the liquid is ejected from the injection nozzle 6 with a high-speed vortex, the liquid is dispersed into fine particles and is atomized.
前記噴出路２は、上記筒体４の外周に螺着の大キャップ
体１５の中央に一体に設けられて貫通し、前端が大キャ
ップ体１５に開口すると共に、後端が前記小キャップ体
５前面に接している。The ejection passage 2 is integrally provided at the center of a large cap body 15 screwed onto the outer periphery of the cylindrical body 4 and passes through it, with a front end opening into the large cap body 15 and a rear end opening into the small cap body 5. It touches the front.
前記通気路３，３は、噴出路２の後端を切欠くことによ
り形成され、また、大キャップ体１５の前面に於いて貫
通孔１６．１６が設けられることにより大キャップ体内
に外気が流入し、これが通気路３，３を通って噴出路２
に入るようになっている。The ventilation passages 3, 3 are formed by notching the rear end of the ejection passage 2, and a through hole 16.16 is provided on the front surface of the large cap body 15 to allow outside air to flow into the large cap body. This passes through the air passages 3, 3 and into the ejection passage 2.
It is designed to enter.
而して、ヘッド本体１に於いて、噴射ノズル６から噴出
した霧は、通常は拡散するが噴出路２があり、これが前
方へテーパー状に次第に狭くなるから、拡散されるべき
霧が噴出路２内で集結され、微粒子に分散された液体が
再度結合する。In the head body 1, the mist ejected from the injection nozzle 6 normally diffuses, but there is an ejection path 2, which gradually narrows in a tapered manner toward the front, so that the mist to be diffused is dispersed through the ejection path. The liquid collected within 2 and dispersed into fine particles is recombined.
また、この際にその流れに伴って通気路３，３から噴出
路２内に外気が流入するので、上記のように液体の微粒
子が再度結合しても液体に戻らず、空気を多量に含んで
泡となる。In addition, at this time, as the outside air flows into the jetting passage 2 from the ventilation passages 3, 3, as described above, even if the liquid particles combine again, they do not return to liquid and contain a large amount of air. It becomes bubbles.
このようにして得られた泡は、液体が一旦微粒子に分散
しているので、均一に多量に空気を含有し、極めて良好
な泡となる。Since the liquid is once dispersed into fine particles, the foam thus obtained uniformly contains a large amount of air, resulting in an extremely good foam.
第２図は他の実施例を示すものである。FIG. 2 shows another embodiment.
この場合も前例とほとんど同じであるが、噴出路２に連
設した案内筒１Ｔを有している。This case is also almost the same as the previous example, but has a guide cylinder 1T connected to the ejection passage 2.
この案内筒は、泡が大キャップ体の前面に広範に付着す
るのを防止する。This guide tube prevents foam from adhering extensively to the front surface of the large cap body.
本案によれば１液体を泡沫化するのに従来のようにスポ
ンジや網等が全く不要で、それらの目詰まり等の障害も
なく、そして、液体がヘッド本体１によって一旦微粒子
の噴霧となり分散され、引き続き大キャップ体の噴出路
２で再び集結され、この際通気路３，３から外気を取り
込んで、泡となるが、ヘッド本体１から噴出するのが微
粒子の噴霧であることから、その泡は、多量の空気を微
細に均一に含有するきめ細かな極めて良好な泡となる。According to the present invention, there is no need for conventional sponges, nets, etc. to turn a liquid into foam, and there are no problems such as clogging of them, and the liquid is once dispersed by the head body 1 as a spray of fine particles. , are then collected again in the jetting passage 2 of the large cap body, and at this time, outside air is taken in from the ventilation passages 3, 3, and it becomes foam, but since what is jetted out from the head body 1 is a spray of fine particles, the foam produces very fine, fine-grained foam that contains a large amount of air finely and uniformly.
また、噴出路２従って大キャップ体１を取外すこともで
き、これ取外してヘッド本体１だゆで使用すると噴霧ヘ
ッドとなり、二様の作用を得る頗る便利なものとなる。In addition, the jetting passage 2 and the large cap body 1 can be removed, and when the head body 1 is used as is, it becomes a spray head, which is extremely convenient and has two functions.
スポンジや網等を要しないので、部品点数が少くなり、
構造並びに製作が簡単となり、安価となる。Since no sponges, nets, etc. are required, the number of parts is reduced.
The structure and production are simple and inexpensive.
