Description

本発明は液体噴出器に関し、詳しくは、収容液を泡状に、しかも泡の塗布パターンを広い範囲になるべく丸く散布することが可能な液体噴出器に関する。   The present invention relates to a liquid ejector, and more particularly, to a liquid ejector that can disperse a contained liquid in a foam shape and in a wide range of a foam application pattern.

容器体に装着して使用し、シリンダ内を加圧及び減圧させて容器体内の液を噴出孔より噴出するポンプ機構を備えた液体噴出器が種々提案されている。(例えば、特許文献1参照)   Various liquid ejectors having a pump mechanism that is used by being attached to a container body, pressurizing and depressurizing the inside of the cylinder, and ejecting the liquid in the container body from the ejection holes have been proposed. (For example, see Patent Document 1)

特許文献1に記載された液体噴出器はトリガー式の液体噴出器であり、本体に揺動可能に装着されたトリガーの操作によりシリンダ内を加圧或いは減圧させることで、容器体内の液を噴出口より噴出する。   The liquid ejector described in Patent Document 1 is a trigger-type liquid ejector, and the liquid inside the container is ejected by pressurizing or depressurizing the inside of the cylinder by operating a trigger swingably attached to the main body. It spouts from the exit.

また、容器体内に垂下固定されるシリンダと、シリンダ内より上部を突出して上方付勢状態で上下動可能に設けられた作動部材とを備え、作動部材の上下動でシリンダ内を加圧及び減圧させることで、容器体内の液を噴出口より噴出する縦型ポンプ式の液体噴出器も知られている。   In addition, a cylinder that is suspended and fixed in the container body and an operating member that protrudes from the inside of the cylinder and that can be moved up and down in an upward biased state are provided. By doing so, there is also known a vertical pump type liquid ejector that ejects the liquid in the container body from the ejection port.

特開平11−290731号公報Japanese Patent Laid-Open No. 11-290731

上記トリガー式の液体噴出器或いは縦型ポンプ式液体噴出器は内部構造により、棒状形態の液状に、或いは霧状、泡状に液を噴出する。霧状に噴出する場合には、例えば、液流路にスピン機構を配置して回動液を噴出口より噴出することで霧状の噴出を可能としている。また、泡状に噴出する場合には外気を導入する機構を備え、外気と液とを混合して起泡する機構を備えている。縦型ポンプ式の液体噴出器の場合、大径の空気用シリンダ小径の液用シリンダを備え、それらに連携する作動部材の上下動により泡状に液を噴出しているが全体構造が大きくなる嫌いがある。また、いずれの液体噴出器の場合も泡を噴出する噴出口が円筒状の噴出口を採用しているため、泡状に噴出する場合にその塗布パターンが狭いという欠点もあった。   The trigger-type liquid ejector or the vertical pump-type liquid ejector ejects liquid in the form of a rod, or in the form of a mist or foam, depending on the internal structure. In the case of spraying in a mist form, for example, a mist-like spray is made possible by arranging a spin mechanism in the liquid flow path and ejecting the rotating liquid from the spout. In addition, a mechanism for introducing outside air is provided in the case of jetting in the form of bubbles, and a mechanism for foaming by mixing outside air and liquid is provided. In the case of a vertical pump type liquid ejector, a large-diameter air cylinder and a small-diameter liquid cylinder are provided, and liquid is ejected in the form of bubbles by the up and down movement of the operating member associated therewith, but the overall structure becomes large I hate it. Further, in any of the liquid ejectors, since the jet outlet for jetting bubbles employs a cylindrical jet outlet, there is also a drawback that the coating pattern is narrow when jetted in a foam form.

本発明は上記した点に鑑みたもので、収容液を泡状に、しかも泡の塗布パターンを広い範囲になるべく丸く散布することが可能であり、しかも、構造も簡単で、製造も容易である液体噴出器を提案するものである。   The present invention has been made in view of the above points, and it is possible to disperse the containing liquid in the form of a foam and to apply the foam application pattern in a wide range as much as possible, and the structure is simple and the manufacture is easy. A liquid ejector is proposed.

第1の手段として、以下の通り構成した。即ち、

外気導入路74からの外気と混合した噴出孔66からの噴霧液を円周面72の大径部72bに衝突させて起泡し、噴出口67の先端開口より噴出可能とし、
テーパ周面73と連続する噴出口67の先端に、拡散程度を調整する調整円周面75を設けた
The first means is configured as follows. That is,
In a liquid ejector that includes a pump mechanism that pressurizes and depressurizes the inside of the cylinder 23 and ejects the liquid in the container B from the ejection hole 66, and ejects the liquid from the ejection hole 66 in a mist form via the spin mechanism 70. And
A foaming diffusion mechanism is provided in front of the ejection hole 66, and the foaming diffusion mechanism is provided with a columnar space-shaped ejection outlet 67 extending ahead of the ejection hole 66, and a base end portion of the ejection outlet 67 is connected to the circumferential surface 72. And a tapered peripheral surface 73 that spreads outward at the tip,
The circumferential surface 72 is composed of a proximal-side small-diameter portion 72a and a distal-end-side large-diameter portion 72b,
One end of an outside air introduction path 74 that communicates with the outside and introduces outside air to the small diameter portion 72a of the circumferential surface 72 is opened,
The spray liquid from the ejection hole 66 mixed with the outside air from the outside air introduction path 74 is caused to collide with the large-diameter portion 72b of the circumferential surface 72 to foam, and can be ejected from the tip opening of the ejection port 67.
An adjustment circumferential surface 75 that adjusts the degree of diffusion is provided at the tip of the ejection port 67 that is continuous with the taper circumferential surface 73 .

の手段として、以下の通り構成した。即ち、前記第の手段に於いて、調整円周面75の先端に、外方へ広がる調整テーパ周面77を連設した。 The second means is configured as follows. That is, in the first means, the adjustment taper circumferential surface 77 extending outward is continuously provided at the tip of the adjustment circumferential surface 75.

3の手段として、以下の通り構成した。即ち、前記第1の手段又は第の手段に於いて、揺動可能に設けられたトリガー操作によりシリンダ23内を加圧及び減圧されるポンプ機構を備えたトリガー式の液体噴出器である。 The third means was configured as follows. That is, the first means or the second means is a trigger type liquid ejector provided with a pump mechanism that pressurizes and depressurizes the inside of the cylinder 23 by a trigger operation provided so as to be swingable.

第4の手段として、以下の通り構成した。即ち、前記第1の手段又は第2の手段に於いて、容器体B内に垂下固定されるシリンダ23と、シリンダ23内より上部を突出させて上方付勢状態で上下動可能に設けられた作動部材80とを備え、作動部材80の上下動でシリンダ23内を加圧及び減圧させる縦型ポンプ式の液体噴出器である。 The fourth means is configured as follows. That is, in the first means or the second means, the cylinder 23 is suspended and fixed in the container body B, and the upper portion projects from the inside of the cylinder 23 so as to be vertically movable in an upwardly biased state. This is a vertical pump type liquid ejector that includes an operating member 80 and pressurizes and depressurizes the inside of the cylinder 23 by the vertical movement of the operating member 80.

本発明によれば、泡パターンを広い範囲になるべく丸く散布することができ、しかも構造が簡単で、噴出孔66より霧状に噴出する機構を備えた液体噴出器の簡単な改良で形成することができる利点がある。   According to the present invention, it is possible to form a bubble pattern with a simple improvement of a liquid ejector that can disperse the bubble pattern as widely as possible, has a simple structure, and has a mechanism for ejecting in a mist form from the ejection hole 66. There is an advantage that can be.

テーパ周面73と連続する噴出口67の先端に、拡散程度を調整する調整円周面75を設けた場合には、散布された泡パターンを必要に応じた拡散状態に調整することができ、泡パターンの輪郭もはっきりした散布を行える。   When the adjustment circumferential surface 75 that adjusts the degree of diffusion is provided at the tip of the spout 67 that is continuous with the taper circumferential surface 73, the dispersed bubble pattern can be adjusted to a diffusion state as necessary, The outline of the foam pattern can also be sprayed clearly.

調整円周面75の先端に、外方へ広がる調整テーパ周面77を連設した場合には、噴出された泡の塗布パターンは、調整円周面75のみ付加した場合と比較して、全体の泡の分散域が拡大することで中央集中域p1の大きさが小さくなる傾向があり、調整円周面75のみ付加した形態と用途によって好ましい選択使用が可能となる。   When the adjustment taper circumferential surface 77 extending outward is continuously provided at the tip of the adjustment circumferential surface 75, the sprayed foam application pattern is entirely compared with the case where only the adjustment circumferential surface 75 is added. The size of the central concentration area p1 tends to be reduced by expanding the dispersion area of the bubbles, and preferable selection and use can be made depending on the form and application in which only the adjustment circumferential surface 75 is added.

円周面72を基端側の小径部72aと、先端側の大径部72bとで構成し、小径部72aに外気導入路74の一端を開口した場合には、外気の導入が噴出孔66近傍の狭い噴出口67内に行われて密な混合が可能となり、また、その後混合液が大径部に衝突してより良好な起泡性を得られる。   When the circumferential surface 72 is composed of a proximal-side small-diameter portion 72a and a distal-end-side large-diameter portion 72b, and one end of the outside air introduction path 74 is opened in the small-diameter portion 72a, the introduction of outside air is the ejection hole 66. It is carried out in the narrow jet port 67 in the vicinity, and intimate mixing becomes possible. Thereafter, the mixed liquid collides with the large diameter portion, and better foaming properties can be obtained.

ノズル60は、連結用筒54外周に回動可能に嵌合させた嵌合筒61を前壁62後面より突設し、また、嵌合筒61内周の前壁62後面からは中心軸53外周に液密回動可能に嵌合する中心筒63を突設している。また、中心筒63の内面後端部所定位置に前後方向に伸びる第2凹溝64を設けており、連結部材50の中心軸53の外面先端部所定位置に設けた前後方向に延びる第1凹溝56とノズル60の所定回動位置では連通が可能に、それ以外の回動位置では連通が不能に構成している。   The nozzle 60 protrudes from the rear surface of the front wall 62 with a fitting tube 61 that is rotatably fitted to the outer periphery of the connecting tube 54, and the central shaft 53 extends from the rear surface of the front wall 62 on the inner periphery of the fitting tube 61. A central cylinder 63 is provided on the outer periphery of the central cylinder 63 so as to be able to rotate in a liquid-tight manner. Further, a second concave groove 64 extending in the front-rear direction is provided at a predetermined position on the inner surface rear end of the central cylinder 63, and a first recess extending in the front-rear direction provided at a predetermined position on the outer surface tip of the central shaft 53 of the connecting member 50. The groove 56 and the nozzle 60 are configured to communicate with each other at a predetermined rotational position, and cannot communicate with other rotational positions.

前壁62の中央部にはスピン機構70を介して噴出孔66が穿設され、噴出孔66の先方に柱状空間形態の噴出口67を延設している。スピン機構70は、前壁62後面に刻設されたもので、図2に示す如く、中央凹部71から螺旋状の放射状凹部68が複数凹設され噴出孔66に連通させたもので、第1凹溝56からの液を噴出孔66から霧状に噴出する機能を果たす。   An ejection hole 66 is formed in the center of the front wall 62 via a spin mechanism 70, and a columnar space-shaped ejection outlet 67 extends from the front of the ejection hole 66. The spin mechanism 70 is engraved on the rear surface of the front wall 62. As shown in FIG. 2, a plurality of spiral radial recesses 68 are formed from the central recess 71 and communicated with the ejection hole 66. The liquid from the concave groove 56 is ejected from the ejection hole 66 in the form of a mist.

本発明では、噴出孔66先方に起泡拡散機構を備えている。起泡拡散機構は、基端部を円周面72とするとともに、先端部に外方へ広がるテーパ周面73を備えた上記柱状空間形態の噴出口67を備えており、また、噴出口67の円周面72に外部と連通して外気を導入する外気導入路74の一端を開口している。そして、外気導入路74からの外気と混合した噴出孔66からの噴霧液を円周面72に衝突させて起泡し、噴出口67の先端開口より噴出可能に構成している。   In the present invention, a foaming diffusion mechanism is provided at the tip of the ejection hole 66. The foaming diffusion mechanism includes a jet outlet 67 in the form of the columnar space having a circumferential end 72 as a base end and a tapered peripheral face 73 spreading outward at a tip end. One end of an outside air introduction path 74 that communicates with the outside and introduces outside air is opened on the circumferential surface 72 of the cylinder. Then, the spray liquid from the ejection hole 66 mixed with the outside air from the outside air introduction path 74 is caused to collide with the circumferential surface 72 to foam, and can be ejected from the tip opening of the ejection port 67.

本例に於ける噴出口67は、前面中央に円形突部76を突設した肉厚の前壁62の中央部に凹設し、奥面中央に噴出孔66を開口した柱状空間形態をなしている。また、円周面72を基端側の小径部72aと、先端側の大径部72bとで構成し、小径部72aの両側に外部と連通して外気を導入する外気導入路74の一端を開口している。更に本例では、テーパ周面73と連続する噴出口67の先端に、拡散程度を調整する調整円周面75を設けている。円周面72及び調整円周面75は、水平軸に沿った横方向にストレートな真円構造であり、これらの円周面と、その周縁部より360°方向に広がるテーパ周面との組み合わせで良好な拡散状態の調整を行える。   The jet outlet 67 in this example has a columnar space shape in which a circular protrusion 76 is provided in the center of the front surface and is recessed in the center of the thick front wall 62, and an outlet hole 66 is opened in the center of the back surface. ing. Further, the circumferential surface 72 is composed of a proximal-side small-diameter portion 72a and a distal-side large-diameter portion 72b, and one end of an outside-air introduction path 74 that communicates with the outside and introduces outside air to both sides of the small-diameter portion 72a. It is open. Further, in this example, an adjustment circumferential surface 75 that adjusts the degree of diffusion is provided at the tip of the ejection port 67 that is continuous with the taper circumferential surface 73. The circumferential surface 72 and the adjustment circumferential surface 75 have a true circular structure that is straight in the horizontal direction along the horizontal axis, and a combination of these circumferential surfaces and a tapered circumferential surface that extends in the 360 ° direction from the peripheral edge portion. Can adjust the diffusion state.

そして、噴出孔66から霧状に噴出する液と外気導入路74からの外気を小径部72a内で混合させた後大径部72bに混合液を衝突させて起泡させ、噴出口67先端開口より泡状に噴出する如く構成している。この際テーパ周面73の存在で泡の塗布パターンが円形に広範囲に広がり、また、調整円周面75により周縁部の輪郭をはっきりさせた泡の過剰な広がり過ぎをおさえた塗布パターンを形成できる。   Then, the liquid ejected in a mist form from the ejection hole 66 and the outside air from the outside air introduction path 74 are mixed in the small diameter part 72a, and then the mixed liquid is caused to collide with the large diameter part 72b to cause foam to be generated. It is configured to eject more like a bubble. At this time, the presence of the tapered peripheral surface 73 allows the foam application pattern to be spread in a wide range in a circular shape, and the adjustment peripheral surface 75 can form an application pattern that suppresses excessive expansion of the foam with a clear peripheral edge. .

Thus, one end of the outside air introduction path 74 for introducing outside air is opened. And the spray liquid from the ejection hole 66 mixed with the outside air from the outside air introduction path 74 collides with the circumferential surface 72 and foams, and the point which is comprised so that it can eject from the front-end | tip opening of the ejection port 67 is 1st. It is the same as that of an Example. In this case as well, the diffusion state can be adjusted with a combination of a straight circular structure in the horizontal direction along the horizontal axis and a tapered peripheral surface extending in the direction of 360 ° from the peripheral edge. A taper structure extending from the structure is provided in two stages to enable finer adjustment.

本例に於ける噴出口67は、前面中央に円形突部76を突設した肉厚の前壁62の中央部に凹設し、奥面中央に噴出孔66を開口した柱状空間形態をなしている。また、円周面72を基端側の小径部72aと、先端側の大径部72bとで構成し、小径部72aの両側に外部と連通して外気を導入する外気導入路74の一端を開口している。テーパ周面73と連続する噴出口67の先端に、拡散程度を調整する調整円周面75を設けており、調整円周面75の先端に、外方へ広がる調整テーパ周面77を連設している。   The jet outlet 67 in this example has a columnar space shape in which a circular protrusion 76 is provided in the center of the front surface and is recessed in the center of the thick front wall 62, and an outlet hole 66 is opened in the center of the back surface. ing.

The outlet 67 is configured to be ejected in the form of bubbles from the opening of the tip. At this time, the foam coating pattern spreads in a circular shape over a wide range due to the presence of the taper circumferential surface 73, and after the adjustment circumferential surface 75 adjusts the spread of the coating pattern to a certain extent, the adjustment taper circumferential surface 77 further applies the coating pattern. To spread.

Is done. The presence of the second diffusion region p3 tends to reduce the size of the central concentration region p1 by expanding the entire bubble dispersion region, and can be selectively used depending on the form and application of the first embodiment. It is.

A fitting cylinder 90 is provided so as to be fitted into the annular groove 86 from the rear surface of the shaped portion 91. The fitting cylinder 90 is fitted into the annular groove 86 and attached to the ejection head 84. Further, a spin mechanism 70 having a similar configuration is engraved on the rear surface of the nozzle 60, and is communicated with the radial recess 68 of the spin mechanism 70 through a gap between the fitting cylinder 90 and the columnar portion 87 from the communication path 88.
