Description

【0001】
【発明の属する技術分野】
本発明は、蒸気を利用して霧化・噴霧された吸入液を吸入することにより、喉や鼻等の呼吸器系に生じた炎症等を治療するのに使用するスチーム式吸入器に関する。
【0002】
【従来の技術】
従来のスチーム式吸入器は、例えば図7に示すようなものである。このスチーム式吸入器は、本体70に吸入液タンク71が着脱可能に取付けられ、吸入液タンク71の吸入液(薬液)を蒸気を利用して吸い上げて霧化する吸入液霧化手段(水タンク、ヒータ、ノズル等で構成されるもの、図示せず)が本体70に内蔵されている。吸入液霧化手段により発生した噴霧は、本体70に設けられた筒部72により本体70外部に放出される。又、本体70には開閉可能なフタ73が螺合されると共に、電源OFF・喉・鼻の選択機能を持つ切替レバー74が設けられている。
【0003】
図7に示す吸入器では、切替レバー74を「喉」にすることで、筒部72から噴霧が放出され、これを喉に吸入することで、喉の炎症等を治療する。鼻の炎症等を治療する場合は、図8に示すように筒部72に鼻用アタッチメント75を取付け、切替レバー74を「鼻」にする。
一方、スチーム式吸入器において、喉と鼻を切替える別のタイプとして、図9及び図10(内部構造の模式図)に示すようなものがある。このスチーム式吸入器では、本体70の筒部77内の噴霧経路に、ノズル80から噴出する蒸気を利用して霧化された噴霧100の流れを案内する遮蔽板81が設けられ、更に噴霧100を喉用と鼻用に切替える制御板82が変位可能に配置されている。レバー(図示せず)の操作により制御板82の位置を変えることで、喉吸入の状態(図9)と鼻吸入の状態(図10)に切り替える。
【0004】
他方、図11に示すようなアタッチメント90を使用するものもある。このアタッチメント90は、喉・鼻の切替機構と噴霧温度調節機構とを独立して備え、各機構に対応する喉・鼻切替レバー92と温度調節つまみ93とを有する。温度調節つまみ93を操作し、蒸気吹出口95から出る蒸気量を増減に調整することで、吸入口99から出る噴霧の温度を調節する。なお、アタッチメント90には、アタッチメントガイド91の他に、空気取入口96が設けられている。
【0005】
【発明が解決しようとする課題】
しかしながら、図7及び図8に示すような従来のスチーム式吸入器では、
a)喉と鼻の切替えの度に鼻用アタッチメント75を着脱する必要がある。
b)喉に吸入する場合、取り外した鼻用アタッチメント75を保管する必要がある。
c)製品として鼻用アタッチメント75の部品が必要である。
の理由から、次のような問題点▲1▼〜▲3▼がある。
▲1▼喉と鼻の切替えに手間取る。
▲2▼取り外しておいた鼻用アタッチメント75を紛失する恐れがあり、保管時に衛生上の問題も生じ易い。
▲3▼鼻用アタッチメント75の部品コストが必要である。
【0006】
又、図9及び図10に示すような従来のスチーム式吸入器では、制御板82で喉と鼻に切り替えても、筒部77から放出される噴霧100が広範囲に広がるので、喉と鼻以外の領域にも噴霧が到達してしまうため、次の問題点▲4▼がある。
▲4▼口や鼻から漏れて吸入できずに無駄になる噴霧量が多く、口から鼻にかけての顔面が濡れる。
【0007】
更に、図11に示すようなアタッチメント90を使用するスチーム式吸入器では、喉・鼻切替用の部品と噴霧温度調節用の部品が個別に必要であるため、次の問題点▲5▼がある。
▲5▼2つの機能の部品コストが必要である。
本発明は、そのような問題点▲1▼〜▲5▼に着目してなされたもので、喉と鼻の切替え機構の簡素性・操作の容易性、部品点数の低減によるコスト削減、喉と鼻への的確な吸入を実現するスチーム式吸入器を提供することを目的とする。
【0008】
【課題を解決するための手段】
前記目的を達成するために、本発明のスチーム式吸入器は、吸入液タンクと、この吸入液タンクの吸入液を蒸気を利用して吸い上げて霧化する吸入液霧化手段と、吸入液霧化手段により発生した噴霧を外部に導く経路を有する筒部とを備え、筒部は、噴霧経路内に吸入液霧化手段により発生した噴霧を経路の一方側に偏らせる遮蔽部と、遮蔽部により経路の一方側に偏らされた噴霧を切り替える経路切替機構とを備え、経路切替機構は、遮蔽部と筒部の噴霧出口である開口との間に設けられ、遮蔽部により経路内の一方側に偏らされた噴霧を遮ることなく流す状態と、該噴霧の流れの方向を噴霧経路内の他方側に変える状態とを切り替える偏向板と、筒部に回転操作可能に取り付けられた筒状のつまみとを備え、偏向板はつまみと共に回動し、所定の回動位置に切り替えることで噴霧の経路を切り替えることを特徴とする。
遮蔽部は、噴霧を経路の下側に偏らせるように設けられ、経路切替機構は、噴霧を遮ることなく経路の下側を流す喉用経路と、噴霧の方向を経路内の上側に変える鼻用経路とに切り替えるようにするのが好適である。
これにより、喉用経路と鼻用経路は噴霧の出口の近くで切り替えられ、噴霧がそれぞれ喉・鼻に向かって集中し易く、喉用には経路が偏向板により遮られることがないため強い噴霧が、鼻用には偏向板により経路が偏向されるため弱い噴霧がそれぞれ行われ、しかも簡単な操作でつまみを回転することで噴霧経路を喉・鼻に切り替えることができる。
【0009】
筒部は遮蔽部と開口との間に空気取入口をさらに備え、つまみは空気取入口を開閉するように筒部の軸方向にも移動操作可能に取り付けられた構成とするのが好適である。これにより、1つのつまみを操作することで噴霧経路の切り替えと噴霧温度調整とが可能となる。
【0010】
【発明の実施の形態】
以下、本発明を実施の形態に基づいて説明する。
一実施形態に係るスチーム式吸入器の外観斜視図を図1に、その分解斜視図を図2に、内部構造の断面図を図3に示す。このスチーム式吸入器は、吸入液(薬液)L1を入れる吸入液タンク2が本体1に着脱可能に設けられ、水L2を入れる水タンク3が本体1内部に配置されている。水タンク3の側部には、水タンク3内の水L2を加熱して蒸発させるヒータ5が配置されている。水タンク3のフタ6は水の補給等を行えるように開閉可能である。更に水タンク3には、ヒータ5による加熱で発生した蒸気を水タンク3外に噴出するノズル7が設けられ、吸入液タンク2に挿入された吸入液吸い上げ用のチューブ9の先端に取付けられたノズル8がノズル7に近接対向している。又、本体1は電源OFF・OFの切替レバー10と電源コード11を備える。
【0011】
本体1の上部にはカバー20が取付けられ、カバー20はノズル7,8の相互作用により発生した噴霧をガイドする噴霧ガイド21を有し、噴霧ガイド21内の噴霧経路には噴霧を経路の一方側に偏らせる遮蔽部22が設けられている。カバー20の噴霧ガイド21には噴霧パイプ40が嵌入され、噴霧パイプ40は吸入口41と複数の空気取入口42を有し、吸入器を使用しないときは吸入口41にキャップ45が被せられる。この実施形態では、噴霧ガイド21と噴霧パイプ40で、噴霧を外部に導く経路を有する筒部が構成される。
【0012】
噴霧ガイド21と噴霧パイプ40との連結部において、噴霧ガイド21と噴霧パイプ40の外周に跨がって、回転操作可能な筒状の喉・鼻切替つまみ30が噴霧ガイド21と噴霧パイプ40の軸方向に移動可能に取付けられている(図4参照)。切替つまみ30は、噴霧パイプ40の吸入口41(開口)に近接して噴霧経路を喉用と鼻用に切り替える経路切替機構としての偏向板31を一体に有する。切替つまみ30を回転操作すれば、それに伴って偏向板31も回転し、この偏向板31の位置により噴霧経路が喉用と鼻用に切り替えられる。
【0013】
又、切替つまみ30は噴霧温度調節機能も併有しており、図4に示すように、切替つまみ30を回転させて軸方向に前後に移動させれば、噴霧パイプ40の空気取入口42を開閉することができ、それにより噴霧の温度を調節できる。
即ち、図4の(a)のように切替つまみ30を噴霧ガイド21側に移動させると、空気取入口42が現れ、空気が空気取入口42から噴霧パイプ40内に進入することで、噴霧と空気が混ざり合い、噴霧の温度が低下する。これに対し、図4の(b)のように切替つまみ30を吸入口41側に移動させると、空気取入口42が切替つまみ30で塞がれ、空気と噴霧が混ざり合わず、温度が高いまま噴霧が吸入口41から放出される。従って、切替つまみ30により空気取入口42の現出度合を変えることで、噴霧温度を高低に調節できる。
【0014】
なお、この実施形態において、偏向板31を有する切替つまみ30は一例であり、他の態様であってもよい。例えば図5に示すような態様であってもよい。図5は、噴霧ガイド21と噴霧パイプ40で構成される筒部49内の構造を簡潔に示す図である。ここでは、筒部49内の噴霧経路の上流側に噴霧ガイド21内の遮蔽部22が配置され、この遮蔽部22に近接して2枚の偏向板35,36が噴霧経路を塞ぐように配置されている。偏向板35は大きい穴35aと4つの小さい穴35bを有し、動かないように固定されている。偏向板36は大きい穴36aのみを有し、回転可能に支持され、筒部49の周囲に設けられた切替つまみ(図示せず)により回転操作することができるようになっている。
【0015】
図5の構造で、喉の吸入を行う場合には、図5の(a)のように偏向板36の穴36aを偏向板35の穴35aに対向させる。こうすれば、遮蔽部22により筒部49内の噴霧経路の一方側に偏って流れる噴霧100の大部分が、そのままの勢いの流れで穴35a,36aを通過し、吸入口41から出る。鼻の吸入を行う場合は、図5の(b)のように偏向板36の穴36aを偏向板35の穴35bに対向させる。すると、遮蔽部22による噴霧100は、穴35a,35bを通過する流れに分流して弱められ、穴36aを通過し吸入口41から出る噴霧100の勢いが弱まる。つまり、偏向板35,36の組合せにより噴霧100の流れを強弱に変えることができる。従って、切替つまみの操作により偏向板36を動かすことで、喉用の強い噴霧と鼻用の弱い噴霧に切り替えることができる。
【0016】
次に、上記のように構成したスチーム式吸入器の作用について説明する。鼻の吸入を行う場合、切替つまみ30を「はな」の位置にする。このとき、切替つまみ30の偏向板31は図6の(a)のような状態になる。そして、切替レバー10を「入」にすると、ヒータ5に通電され、水タンク3内の水L2が加熱されて沸騰し、蒸気が発生する。蒸気はノズル7から噴出するが、ノズル7に近接対向してノズル8が位置決めされているので、ノズル8の先端に負圧が生じ、この負圧により吸入液タンク2内の吸入液L1がチューブ9を通じて吸い上げられ、ノズル8から出ると同時にノズル7から噴出する蒸気により霧化される。
【0017】
この蒸気と霧化吸入液の混合物(噴霧)100は、図6の(a)に示すように、噴霧ガイド21の遮蔽部22により噴霧経路の一方側に偏って流れ、更に偏向板31により流れる方向が上向きに変わり、噴霧パイプ40(吸入口41)から鼻に向かって放出される。このときの噴霧100は、偏向板31により流れの勢いが弱まっているので、鼻の吸入に適したものとなる。
【0018】
一方、喉の吸入を行う場合には、切替つまみ30を「のど」の位置にする。このとき、切替つまみ30の偏向板31は図6の(b)のような状態になる。そして、切替レバー10を「入」にすると、同様にノズル7,8の相互作用により噴霧100が生じる。噴霧100は、図6の(b)に示すように、遮蔽部22により噴霧経路の一方側に偏って流れ、偏向板31で流れが遮られることなく偏向板31を通過し、噴霧パイプ40から喉に向かって放出される。このときの噴霧100は、強い流れの勢いのままであるので、喉の吸入に適したものとなる。
【0019】
このように、切替つまみ30の簡単な操作により、噴霧を喉と鼻に容易に切り替えることができるだけでなく、噴霧の温度調節も行うことができる。しかも、1つの部品の切替つまみ30の偏向板31の向きを変える簡単な構造であり、部品点数及びコストを削減できる。
【0020】
【発明の効果】
本発明のスチーム式吸入器は、以上説明したように構成されるため、喉・鼻への噴霧経路ならびに噴霧強度の切り替えが簡単な構成で効率的に実現でき、しかも切り替えのための操作も簡単に行うことができるという効果を奏する。さらに、噴霧経路と噴霧温度調整とを1つのつまみで操作することができるという効果も奏する。

BACKGROUND OF THE INVENTION
The present invention relates to a steam-type inhaler used for treating inflammation and the like occurring in a respiratory system such as a throat and a nose by inhaling an inhaled liquid atomized and sprayed using steam.
[0002]
[Prior art]
A conventional steam inhaler is, for example, as shown in FIG. In this steam type inhaler, an inhalation liquid tank 71 is detachably attached to a main body 70, and an inhalation liquid atomizing means (water tank) for sucking inhalation liquid (chemical solution) from the inhalation liquid tank 71 using steam. , A heater, a nozzle, etc. (not shown) are built in the main body 70. The spray generated by the inhalation liquid atomizing means is discharged to the outside of the main body 70 by the cylindrical portion 72 provided in the main body 70. In addition, a lid 73 that can be opened and closed is screwed to the main body 70, and a switching lever 74 having a function of selecting power OFF, throat, and nose is provided.
[0003]
In the inhaler shown in FIG. 7, the spray is released from the cylindrical portion 72 by setting the switching lever 74 to “throat”, and the inhalation of the spray into the throat treats inflammation of the throat. When treating inflammation of the nose or the like, a nose attachment 75 is attached to the cylindrical portion 72 as shown in FIG. 8, and the switching lever 74 is set to “nose”.
On the other hand, in the steam type inhaler, another type for switching between the throat and the nose is as shown in FIGS. 9 and 10 (schematic diagrams of the internal structure). In this steam-type inhaler, a shielding plate 81 that guides the flow of the atomized spray 100 using the steam ejected from the nozzle 80 is provided in the spray path in the cylindrical portion 77 of the main body 70. A control plate 82 for switching between throat use and nose use is displaceably disposed. By changing the position of the control plate 82 by operating a lever (not shown), the throat inhalation state (FIG. 9) and the nasal inhalation state (FIG. 10) are switched.
[0004]
On the other hand, there is also one using an attachment 90 as shown in FIG. The attachment 90 includes a throat / nose switching mechanism and a spray temperature adjustment mechanism independently, and has a throat / nose switching lever 92 and a temperature adjustment knob 93 corresponding to each mechanism. The temperature of the spray coming out from the suction port 99 is adjusted by operating the temperature adjustment knob 93 and adjusting the amount of steam coming out from the steam outlet 95 to increase or decrease. The attachment 90 is provided with an air intake 96 in addition to the attachment guide 91.
[0005]
[Problems to be solved by the invention]
However, in the conventional steam inhaler as shown in FIGS. 7 and 8,
a) It is necessary to attach and detach the nasal attachment 75 every time the throat and the nose are switched.
b) When inhaling into the throat, the removed nasal attachment 75 needs to be stored.
c) The parts of the nasal attachment 75 are required as products.
For this reason, there are the following problems (1) to (3).
(1) Take time to switch between throat and nose.
(2) The removed nasal attachment 75 may be lost, and hygiene problems are likely to occur during storage.
(3) The parts cost of the nose attachment 75 is required.
[0006]
Further, in the conventional steam type inhaler as shown in FIGS. 9 and 10, even if the control plate 82 switches between the throat and the nose, the spray 100 discharged from the cylindrical portion 77 spreads over a wide range. Since the spray reaches the region, there is the following problem (4).
(4) The amount of spray that is wasted due to leakage from the mouth and nose cannot be inhaled, and the face from the mouth to the nose gets wet.
[0007]
Furthermore, in the steam type inhaler using the attachment 90 as shown in FIG. 11, the parts for switching the throat and nose and the parts for adjusting the spray temperature are separately required, and therefore there is the following problem (5). .
(5) Parts costs for two functions are required.
The present invention has been made paying attention to such problems (1) to (5). The throat and nose switching mechanism is simple and easy to operate, the cost is reduced by reducing the number of parts, the throat and It aims at providing the steam type inhaler which implement | achieves exact inhalation to a nose.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a steam type inhaler according to the present invention comprises an inhalation liquid tank, an inhalation liquid atomizing means for sucking and atomizing the inhalation liquid in the inhalation liquid tank using steam, and an inhalation liquid fog A cylindrical portion having a path for guiding the spray generated by the atomizing means to the outside, and the cylindrical portion biases the spray generated by the inhalation liquid atomizing means in the spray path toward one side of the path; And a path switching mechanism that switches the spray biased to one side of the path, and the path switching mechanism is provided between the shielding part and the opening that is the spray outlet of the cylinder part, and one side in the path by the shielding part A deflection plate that switches between a state in which the spray biased to the flow is unobstructed and a state in which the direction of the flow of the spray is changed to the other side in the spray path, and a cylindrical knob that is rotatably attached to the cylindrical portion The deflection plate rotates with the knob. And switches the spray path by switching to a predetermined rotational position.
The shielding part is provided so as to bias the spray toward the lower side of the path, and the path switching mechanism includes a throat path that flows below the path without blocking the spray, and a nose that changes the direction of the spray to the upper side in the path. It is preferable to switch to the use route.
As a result, the throat route and the nasal route are switched near the spray outlet, and the spray is likely to concentrate toward the throat and nose, respectively. However, since the path is deflected by the deflecting plate for the nose, weak spraying is performed, and the spraying path can be switched to the throat / nose by rotating the knob with a simple operation.
[0009]
It is preferable that the cylindrical portion further includes an air intake between the shielding portion and the opening, and the knob is attached so as to be movable in the axial direction of the cylindrical portion so as to open and close the air intake. . Thereby, it is possible to switch the spray path and adjust the spray temperature by operating one knob.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments.
FIG. 1 is an external perspective view of a steam inhaler according to an embodiment, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a sectional view of the internal structure. In this steam type inhaler, an inhalation liquid tank 2 for containing an inhalation liquid (chemical solution) L1 is detachably provided on the main body 1, and a water tank 3 for containing water L2 is disposed inside the main body 1. A heater 5 that heats and evaporates the water L2 in the water tank 3 is disposed on the side of the water tank 3. The lid 6 of the water tank 3 can be opened and closed so that water can be replenished. Further, the water tank 3 is provided with a nozzle 7 for ejecting steam generated by heating by the heater 5 to the outside of the water tank 3, and is attached to the tip of a tube 9 for sucking up the suction liquid inserted into the suction liquid tank 2. The nozzle 8 is in close proximity to the nozzle 7. The main body 1 includes a power supply OFF / OF switching lever 10 and a power cord 11.
[0011]
A cover 20 is attached to the upper part of the main body 1, and the cover 20 has a spray guide 21 that guides the spray generated by the interaction of the nozzles 7, 8. The shielding part 22 which is biased to the side is provided. A spray pipe 40 is fitted into the spray guide 21 of the cover 20, and the spray pipe 40 has a suction port 41 and a plurality of air intake ports 42, and a cap 45 is put on the suction port 41 when the inhaler is not used. In this embodiment, the spray guide 21 and the spray pipe 40 constitute a cylindrical portion having a path for guiding the spray to the outside.
[0012]
At the connecting portion between the spray guide 21 and the spray pipe 40, a cylindrical throat / nose switching knob 30 that can be rotated over the outer periphery of the spray guide 21 and the spray pipe 40 is provided between the spray guide 21 and the spray pipe 40. It is attached so as to be movable in the axial direction (see FIG. 4). The switching knob 30 integrally includes a deflection plate 31 as a path switching mechanism that switches between the throat and the nose in the vicinity of the suction port 41 (opening) of the spray pipe 40. When the switching knob 30 is rotated, the deflection plate 31 is also rotated accordingly, and the spray path is switched between the throat and the nose depending on the position of the deflection plate 31.
[0013]
The switching knob 30 also has a spray temperature adjusting function. As shown in FIG. 4, when the switching knob 30 is rotated and moved back and forth in the axial direction, the air intake 42 of the spray pipe 40 is opened. It can be opened and closed, thereby adjusting the spray temperature.
That is, when the switching knob 30 is moved toward the spray guide 21 as shown in FIG. 4A, the air intake 42 appears, and air enters the spray pipe 40 from the air intake 42, thereby Air mixes and spraying temperature decreases. On the other hand, when the switching knob 30 is moved to the inlet 41 side as shown in FIG. 4B, the air intake 42 is blocked by the switching knob 30, the air and the spray are not mixed, and the temperature is high. The spray is discharged from the suction port 41 as it is. Therefore, the spray temperature can be adjusted to be high or low by changing the degree of appearance of the air intake 42 by the switching knob 30.
[0014]
In this embodiment, the switching knob 30 having the deflection plate 31 is an example, and other modes may be used. For example, an embodiment as shown in FIG. FIG. 5 is a diagram simply showing the structure in the cylindrical portion 49 composed of the spray guide 21 and the spray pipe 40. Here, the shielding part 22 in the spray guide 21 is arranged on the upstream side of the spraying path in the cylindrical part 49, and the two deflecting plates 35 and 36 are arranged close to the shielding part 22 so as to block the spraying path. Has been. The deflection plate 35 has a large hole 35a and four small holes 35b, and is fixed so as not to move. The deflection plate 36 has only a large hole 36a, is rotatably supported, and can be rotated by a switching knob (not shown) provided around the cylinder portion 49.
[0015]
In the structure of FIG. 5, when the throat is inhaled, the hole 36 a of the deflection plate 36 is opposed to the hole 35 a of the deflection plate 35 as shown in FIG. In this way, most of the spray 100 that flows biased to one side of the spray path in the cylindrical portion 49 by the shielding portion 22 passes through the holes 35a and 36a as it is, and exits from the suction port 41. When inhaling the nose, the hole 36a of the deflection plate 36 is made to face the hole 35b of the deflection plate 35 as shown in FIG. Then, the spray 100 by the shielding part 22 is diverted and weakened by the flow passing through the holes 35a and 35b, and the momentum of the spray 100 passing through the hole 36a and exiting from the suction port 41 is weakened. That is, the flow of the spray 100 can be changed in strength by the combination of the deflection plates 35 and 36. Therefore, by moving the deflection plate 36 by operating the switching knob, it is possible to switch between strong spray for the throat and weak spray for the nose.
[0016]
Next, the operation of the steam inhaler configured as described above will be described. When inhaling the nose, the switching knob 30 is set to the “Hana” position. At this time, the deflection plate 31 of the switching knob 30 is in a state as shown in FIG. When the switching lever 10 is set to “ON”, the heater 5 is energized, the water L2 in the water tank 3 is heated and boiled, and steam is generated. Although the steam is ejected from the nozzle 7, the nozzle 8 is positioned so as to be close to and opposed to the nozzle 7, so that a negative pressure is generated at the tip of the nozzle 8. 9 is sucked up through 9 and atomized by steam ejected from the nozzle 7 at the same time as it exits the nozzle 8.
[0017]
As shown in FIG. 6A, the mixture (spray) 100 of the vapor and the atomized inhalation liquid is biased to one side of the spray path by the shielding portion 22 of the spray guide 21 and further flows by the deflecting plate 31. The direction changes upward and is discharged from the spray pipe 40 (suction port 41) toward the nose. The spray 100 at this time is suitable for inhalation of the nose because the momentum of the flow is weakened by the deflection plate 31.
[0018]
On the other hand, when the throat is inhaled, the switching knob 30 is set to the “throat” position. At this time, the deflection plate 31 of the switching knob 30 is in a state as shown in FIG. When the switching lever 10 is set to “ON”, the spray 100 is similarly generated by the interaction of the nozzles 7 and 8. The spray 100 flows toward the one side of the spray path by the shielding part 22 and passes through the deflecting plate 31 without being blocked by the deflecting plate 31 as shown in FIG. It is released toward the throat. The spray 100 at this time remains in a strong flow momentum, and is suitable for inhalation of the throat.
[0019]
Thus, by a simple operation of the switching knob 30, not only can the spray be easily switched between the throat and the nose, but also the temperature of the spray can be adjusted. In addition, the structure is a simple structure that changes the direction of the deflection plate 31 of the switching knob 30 for one part, and the number of parts and the cost can be reduced.
[0020]
【The invention's effect】
Since the steam inhaler according to the present invention is configured as described above , the spray path to the throat and nose and the spray intensity can be switched efficiently with a simple configuration, and the operation for switching is also simple. The effect that it can be performed is produced. Furthermore, there is an effect that the spraying path and the spraying temperature adjustment can be operated with one knob.
