従来、水や湯の温度を確認せずに噴射ヘッドから湯水を噴射させてしまい、熱湯や冷水を直接人肌に浴びせてしまうことがよくある。 Conventionally, hot water or hot water is often ejected from an ejection head without checking the temperature of water or hot water, and hot or cold water is often directly applied to human skin.

本発明の目的は、使用前の温度確認を怠りにくい噴射ヘッドを提供することにある。 An object of the present invention is to provide an ejection head in which it is difficult to neglect the temperature before use.

本発明の噴射ヘッドは、液体を噴射する噴射口と、把持部と、前記供給口から前記把持部内を通って前記噴射口へと向かう液体流路と、外部から前記液体流路内へと液体が供給される供給口とが形成されたヘッド本体を備えており、前記ヘッド本体において前記把持部又はその周辺の表面に、前記液体流路に連通する、手指を挿入可能な貫通孔が開口している。 The ejection head according to the present invention includes an ejection port for ejecting liquid, a gripping portion, a liquid flow path from the supply port to the ejection port through the gripping portion, and liquid from the outside into the liquid flow path. And a through hole through which a finger can be inserted is connected to the surface of the gripping portion or its periphery in the head body and into which the finger can be inserted. ing.

本発明の噴射ヘッドによると、把持部又はその周辺に貫通孔があるので、この貫通孔を指で塞がないと内部の液体が漏れてしまう。したがって、貫通孔に指を入れて使用する傾向が強まる。貫通孔に指を入れると指が内部の液体に触れるので、使用前の温度確認を怠りにくくなる。 According to the ejection head of the present invention, since there is a through hole in the gripping portion or the periphery thereof, the liquid inside leaks unless the through hole is blocked with a finger. Therefore, the tendency to use a finger in the through hole is increased. When a finger is put into the through hole, the finger touches the liquid inside, so that it is difficult to neglect the temperature check before use.

また、本発明においては、前記ヘッド本体において前記噴射口が形成された正面とは反対側の背面に前記貫通孔が開口していてもよい。これによると、右手の場合にも左手の場合にも親指を挿入しやすい位置に貫通孔を配置できる。 In the present invention, the through hole may be open on the back surface of the head body opposite to the front surface on which the ejection port is formed. According to this, a through-hole can be arrange | positioned in the position which is easy to insert a thumb also in the case of the right hand and the left hand.

また、本発明においては、前記背面において前記把持部より前記供給口から遠い領域が、背後に向かって突出した突出領域を含んでおり、前記突出領域において前記把持部側の位置に前記貫通孔が開口していることが好ましい。これによると、突出領域の把持部側に貫通孔が形成されているため、把持部を握った際に親指を把持部側から貫通孔に挿入しやすい。 In the present invention, a region of the back surface that is farther from the supply port than the gripping portion includes a protruding region that protrudes toward the back, and the through-hole is located at a position on the gripping portion side in the protruding region. An opening is preferred. According to this, since the through hole is formed on the grip portion side of the protruding region, it is easy to insert the thumb into the through hole from the grip portion side when the grip portion is gripped.

また、本発明においては、前記貫通孔が、前記ヘッド本体の表面の垂線に交差する方向に沿った内表面を有していることが好ましい。これによると、貫通孔がヘッド表面から内部の液体流路まで斜めに形成されるので、指を沿わせやすい構成となる。 In the present invention, it is preferable that the through hole has an inner surface along a direction intersecting with a perpendicular of the surface of the head body. According to this, since the through hole is formed obliquely from the head surface to the internal liquid flow path, it is easy to place the finger along.

また、本発明においては、前記ヘッド本体に、前記貫通孔より大きい嵌め込み孔が形成されており、前記貫通孔が形成された嵌め込み部材が、前記嵌め込み孔に着脱可能に嵌め込まれていることが好ましい。これによると、さまざまな大きさ、形状の貫通孔が形成された嵌め込み部材を用意することで、指の太さや形状に合う貫通孔を選択可能な噴射ヘッドが実現する。 Further, in the present invention, it is preferable that a fitting hole larger than the through hole is formed in the head body, and a fitting member in which the through hole is formed is detachably fitted into the fitting hole. . According to this, by providing a fitting member in which through holes having various sizes and shapes are formed, an ejection head capable of selecting a through hole that matches the thickness and shape of the finger is realized.

以下、本発明の好適な一実施形態について説明する。図１は、本実施形態に係るシャワーヘッド（噴射ヘッド）１の斜視図である。図２はシャワーヘッド１の背面図であり、図３は図２のＩＩＩ−ＩＩＩ線断面図である。 Hereinafter, a preferred embodiment of the present invention will be described. FIG. 1 is a perspective view of a shower head (jet head) 1 according to the present embodiment. 2 is a rear view of the shower head 1, and FIG. 3 is a cross-sectional view taken along line III-III in FIG.

図１〜３に示すように、シャワーヘッド１は、複数の湯水の噴射口３が正面に形成されたヘッド本体２を有している。ヘッド本体２は、図１の上下方向に細長い棒状の概略形状を有しており、噴射口３はヘッド本体２の上部に配置されている。ヘッド本体２の下部には把持部５が設けられている。把持部５は概略的に円筒形状であり、ユーザはシャワーヘッド１を使用する際、把持部５を把持する。ヘッド本体２の下端には接続部４が設けられている。接続部４は、シャワーヘッド１に湯水を供給するシャワーホースなどに接続される部分である。接続部４の下面には、湯水の供給口４ａが開口している。 As shown in FIGS. 1 to 3, the shower head 1 has a head body 2 in which a plurality of hot water jets 3 are formed on the front surface. The head body 2 has a substantially bar-like shape that is elongated in the vertical direction of FIG. 1, and the ejection port 3 is disposed at the top of the head body 2. A grip 5 is provided at the bottom of the head body 2. The grip portion 5 has a generally cylindrical shape, and the user grips the grip portion 5 when using the shower head 1. A connecting portion 4 is provided at the lower end of the head body 2. The connection portion 4 is a portion connected to a shower hose that supplies hot water to the shower head 1. A hot water supply port 4 a is open on the lower surface of the connecting portion 4.

図３に示すように、ヘッド本体２の内部には湯水の流路８が形成されている。流路８は、下端において供給口４ａに連通しており、上部において噴射口３と連通している。供給口４ａから供給された湯水は流路８を通って噴射口３から噴射される。 As shown in FIG. 3, a hot water flow path 8 is formed inside the head body 2. The flow path 8 communicates with the supply port 4a at the lower end and communicates with the injection port 3 at the upper part. Hot and cold water supplied from the supply port 4 a is jetted from the jet port 3 through the flow path 8.

図２、図３に示すように、ヘッド本体２の背面には突出部２ａ（突出領域）が形成されている。突出部２ａは、ヘッド本体２の背面が後方に向かって突出した部分であり、把持部５の少し上方に形成されている。突出部２ａにおいてヘッド本体２の正面から最も離れた頂部より把持部５に近い、図２、図３に示す領域２ｂは、ほぼ平面に沿って延びている。領域２ｂの図２において左右方向に中央近傍には嵌め込み孔２ｃが形成され、その嵌め込み孔２ｃに嵌め込み部材７がはめ込まれている。 As shown in FIGS. 2 and 3, a protrusion 2 a (protrusion region) is formed on the back surface of the head body 2. The protruding portion 2 a is a portion where the back surface of the head body 2 protrudes rearward, and is formed slightly above the grip portion 5. A region 2b shown in FIG. 2 and FIG. 3 that is closer to the gripping portion 5 than a top portion farthest from the front surface of the head body 2 in the protruding portion 2a extends substantially along a plane. In FIG. 2 of the region 2b, a fitting hole 2c is formed near the center in the left-right direction, and the fitting member 7 is fitted into the fitting hole 2c.

図４（ａ）は嵌め込み部材７の拡大断面図である。嵌め込み部材７は、ゴムなどの弾性材料から構成されており、円筒形の概略形状を有している。嵌め込み部材７の周面には突起７ａ及び７ｂが形成されている一方で、嵌め込み孔２ｃも突起７ａ及び７ｂがちょうど嵌まるように形成されている。突起７ａは突起７ｂに比べて短くなっており、突起７ａをヘッド本体２の外側から嵌め込み孔２ｃの開口を通すように嵌め込み孔２ｃの流路８側に嵌め込むことで、嵌め込み部材７を嵌め込み孔２ｃに嵌め込むことができるようになっている。 FIG. 4A is an enlarged cross-sectional view of the fitting member 7. The fitting member 7 is made of an elastic material such as rubber and has a substantially cylindrical shape. While the protrusion 7a and 7b are formed in the surrounding surface of the fitting member 7, the fitting hole 2c is also formed so that the protrusions 7a and 7b may just fit. The projection 7a is shorter than the projection 7b, and the projection 7a is fitted into the channel 8 side of the fitting hole 2c so as to pass through the opening of the fitting hole 2c from the outside of the head main body 2, so that the fitting member 7 is fitted. It can be fitted in the hole 2c.

嵌め込み部材７の内部には、円筒の一方の底面から他方の底面まで貫通する貫通孔６が形成されている。貫通孔６は、図４（ａ）に示すように、円筒の底面に直交する方向Ａに交差する方向に沿った内表面を有している。方向Ａは、嵌め込み部材７を嵌め込み孔２ｃにはめ込んだ際における領域２ｂの垂線方向に相当する。これにより、この内表面は、嵌め込み部材７を嵌め込み孔２ｃにはめ込んだ際に、図３に示すようにちょうど把持部５を握った手の親指をぴったり挿入できるような形状に形成されている。なお、貫通孔６は、ヘッド本体２の背面に配置されており、且つ、図２においてヘッド本体２の左右方向について中央近傍に配置されている。このため、把持部５を右手で握った場合にも左手に握った場合にも、いずれの場合にも親指を挿入しやすい。 A through hole 6 is formed in the fitting member 7 so as to penetrate from one bottom surface of the cylinder to the other bottom surface. As shown in FIG. 4A, the through hole 6 has an inner surface along a direction intersecting a direction A perpendicular to the bottom surface of the cylinder. The direction A corresponds to the perpendicular direction of the region 2b when the fitting member 7 is fitted into the fitting hole 2c. As a result, when the fitting member 7 is fitted into the fitting hole 2c, the inner surface is formed in such a shape that the thumb of the hand holding the holding portion 5 can be inserted exactly as shown in FIG. The through hole 6 is disposed on the back surface of the head body 2 and is disposed near the center in the left-right direction of the head body 2 in FIG. For this reason, it is easy to insert the thumb in both cases when the grip portion 5 is gripped with the right hand and when it is gripped with the left hand.

また、嵌め込み部材７は弾性材料で構成されており、変形しやすく、嵌め込み孔２ｃへと着脱自在に構成されている。これにより、例えば図４（ｂ）及び図４（ｃ）に示す嵌め込み部材１７や２７と嵌め込み部材７とを交換することができる。嵌め込み部材１７に形成された貫通孔１６は、嵌め込み部材７の貫通孔６と比べて径が小さく、嵌め込み部材７を使う場合よりも小さい親指を挿入させるのに適している。また、嵌め込み部材２７に形成された貫通孔２６は、嵌め込み部材７の貫通孔６と比べて、流路８側に向かって先細りの形状を有している。これにより、挿入した親指を押し込むことで、貫通孔２６を確実に塞ぐことができると共に、親指を貫通孔２６内にしっかり固定することができる。 The fitting member 7 is made of an elastic material, is easily deformed, and is detachable from the fitting hole 2c. Thereby, for example, the fitting members 17 and 27 and the fitting member 7 shown in FIGS. 4B and 4C can be exchanged. The through-hole 16 formed in the fitting member 17 has a smaller diameter than the through-hole 6 of the fitting member 7 and is suitable for inserting a thumb smaller than the case where the fitting member 7 is used. Further, the through hole 26 formed in the fitting member 27 has a tapered shape toward the flow path 8 side as compared with the through hole 6 of the fitting member 7. Thereby, by pushing in the inserted thumb, the through hole 26 can be reliably closed and the thumb can be firmly fixed in the through hole 26.

以上説明した本実施形態によると、把持部５の近傍に流路８に連通する貫通孔６が形成されているので、図３のように親指を挿入して貫通孔６を塞がなければ流路８内の湯水が貫通孔６から漏れ出してしまう。したがって、シャワーヘッド１を使用する際は貫通孔６に親指を挿入して使用するようになる。このため、親指が直接湯水に触れてその温度を感知することができるので、シャワーヘッド１からの湯水を使用する前に温度確認するのを怠りにくくなる。また、貫通孔６に親指を挿入することで、シャワーヘッド１を安定して把持できる。 According to the present embodiment described above, since the through hole 6 communicating with the flow path 8 is formed in the vicinity of the grip portion 5, if the thumb is inserted and the through hole 6 is not blocked as shown in FIG. Hot water in the passage 8 leaks from the through hole 6. Therefore, when using the shower head 1, the thumb is inserted into the through hole 6. For this reason, since the thumb can touch the hot water directly and sense the temperature, it becomes difficult to neglect to check the temperature before using the hot water from the shower head 1. Moreover, the shower head 1 can be stably held by inserting a thumb into the through hole 6.

例えば、介護、看護業界の現場では、シャワーの温度確認を怠って被介護者、被看護者に冷水や熱水をかけてしまう事故が考えられる。このような現場に、貫通孔に指を挿入して使用することが前提となる本実施形態を採用すると、温度確認を怠りにくくなるため、上記のような事故を効果的に抑制することが可能である。 For example, in the field of the nursing and nursing industry, there may be an accident in which the temperature of the shower is neglected and cold water or hot water is applied to the care recipient or the nurse. Adopting this embodiment, which is based on the premise that a finger is inserted into a through-hole in such a field, makes it difficult to neglect the temperature, so it is possible to effectively suppress the above accidents. It is.

また、さまざまな形状の貫通孔６〜２６が形成された嵌め込み部材７〜２７等を選択的に嵌め込み孔２ｃに嵌め込み可能な構成であるため、指の太さや形状に合う貫通孔を選択可能である。 In addition, since the fitting members 7 to 27 and the like in which the through holes 6 to 26 having various shapes are formed can be selectively fitted into the fitting holes 2c, the through holes that match the thickness and shape of the finger can be selected. is there.

以上は、本発明の好適な実施形態についての説明であるが、本発明は上述の実施形態に限られるものではなく、課題を解決するための手段に記載された範囲の限りにおいて様々な変更が可能なものである。 The above is a description of a preferred embodiment of the present invention, but the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope described in the means for solving the problem. It is possible.

上述の実施形態では貫通孔６がヘッド本体２の背面に形成されており、親指を挿入することを想定しているが、親指以外の指を挿入できるように貫通孔が形成されていてもよい。例えば、把持部５の側面に人差し指を挿入するように形成されていたり、中指を挿入するように形成されていたりしてもよい。 In the above-described embodiment, the through hole 6 is formed on the back surface of the head body 2 and it is assumed that a thumb is inserted. However, the through hole may be formed so that a finger other than the thumb can be inserted. . For example, it may be formed so as to insert an index finger on the side surface of the grip portion 5 or may be formed so as to insert a middle finger.

また、上述の実施形態では、下方から親指を挿入しやすいように、貫通孔６の内表面が図３の方向Ａに交差する方向に沿っている。しかし、例えば、領域２ｂが図３よりさらに下方に向かって傾いている場合などには、貫通孔６の内表面が方向Ａに沿って形成されていてもよい。要は、指を挿入しやすい方向に沿っていることが好ましい。 Moreover, in the above-mentioned embodiment, the inner surface of the through-hole 6 is along the direction which cross | intersects the direction A of FIG. 3 so that it may be easy to insert a thumb from the downward direction. However, for example, when the region 2b is inclined further downward than in FIG. 3, the inner surface of the through hole 6 may be formed along the direction A. In short, it is preferable to follow the direction in which a finger can be easily inserted.
