Description

本願発明は、吸引式噴射器に関する。 The present invention relates to a suction type injector.

特開平１０−３０５２４３号公報JP-A-10-305243

従来、エアゾールの噴射器において、被噴射物と、噴射用の圧縮ガスとが同一のエアゾール容器（噴射ボンベ）に収容されたものが、一般的であったが、上記特許文献１に示されるように、最近では、噴射ボンベには、圧縮ガスのみを収容し、被噴射物（特許文献１において塗料）を別途の容器に収容し、上記圧縮ガスの噴射にて発生する負圧を利用して、被噴射物を容器より吸い上げ噴射するもの（吸引式噴射器）が見受けられる。
上記の噴射用のガスとして、圧縮ガス以外の他、用途によって、液化ガスを利用することが考えられる。
液化ガスは、ボンベ中、気体部分と液体部分の２相になっており、使用時、当該気体部分が、ボンベから噴射される。 Conventionally, in an aerosol injector, an object to be injected and a compressed gas for injection are generally accommodated in the same aerosol container (injection cylinder). Recently, only the compressed gas is stored in the injection cylinder, and the injection target (paint in Patent Document 1) is stored in a separate container, and the negative pressure generated by the injection of the compressed gas is used. There can be seen what sucks up and injects the injection target from the container (suction type injector).
As the above-mentioned gas for injection, it is conceivable to use a liquefied gas depending on the use other than the compressed gas.
The liquefied gas has two phases of a gas part and a liquid part in the cylinder, and the gas part is jetted from the cylinder at the time of use.

しかし、第１の課題として、液化ガスでは、気化したガスの噴射に、液化した部分の気化が間に合わず、噴射の勢いがすぐに減衰してしまう傾向がある。
また、第２の課題として、噴射器を正立状態で使用する他、倒立させた状態で使用したい場合がある。このような場合、液化ガスでは、ボンベの上下に拘わらず、常に液状の部分より上方に位置する気化した部分を噴射すると共に、液体の被噴射物について、容器の上下に拘わらず、容器中の空気よりも常に下方に位置する液体を吸引する必要がある。液化ガスを利用する吸引式噴射器において、このような正立状態及び倒立状態の双方の使用に、簡単な構成で十分対処できるものは見当たらない。 However, as a first problem, in the liquefied gas, vaporization of the liquefied portion is not in time for the vaporized gas injection, and the momentum of the injection tends to be attenuated immediately.
Further, as a second problem, there is a case where it is desired to use the injector in an inverted state in addition to using the injector in an upright state. In such a case, the liquefied gas always injects the vaporized portion located above the liquid portion regardless of the upper and lower sides of the cylinder, and the liquid ejected object in the container regardless of the upper and lower sides of the container. It is necessary to suck the liquid that is always below the air. There is no suction injector using a liquefied gas that can sufficiently cope with the use of both the upright state and the inverted state with a simple configuration.

本願発明第１の発明は、液化ガスを利用する吸引式噴射器において、ボンベ中の液化ガスの気化を促す手段を提供し、上記第１の課題の解決を図る。また、本願第２及び第３の発明は、噴射器の正立・倒立何れの状態においても、円滑な噴射を行うことが可能な手段を提供して、上記第２の課題の解決を図る。 The first invention of the present application provides means for promoting the vaporization of the liquefied gas in the cylinder in the suction type injector utilizing the liquefied gas, and aims to solve the first problem. In addition, the second and third inventions of the present application provide means capable of performing smooth injection regardless of whether the injector is upright or inverted, thereby solving the second problem.

そこで、本願第１の発明は、噴射機構部３と、この噴射機構部に接続された噴射ボンベ２と、噴射ボンベ２とは別個に噴射機構部３に接続された被噴射物収納室４とを備え、噴射機構部３は、噴射ボンベ２のガスを噴出させることにより被噴射物収納室４の被噴射物を吸引して噴射させるものである吸引式噴射器について、次の構成を採るものを提供する。

Each of the first and second flow paths 23, 43, 24, and 44 has one end connected to the injection cylinder 2 or the opening of the injection object storage chamber 4, and the other end being an open end. In the upright state of the injector, the open ends of the first flow paths 23 and 43 are positioned below the liquid level, and the open ends of the second flow paths 24 and 44 are positioned above the liquid level. To do. In the inverted state of the injector, the open ends of the first flow paths 23 and 43 are located above the liquid level, and the open ends of the second flow paths 24 and 44 are located below the liquid level. . The valve means of the injection cylinder communicates vaporized gas above the liquid level through the second flow path 24 to the injection mechanism section 3 during the injection in the upright state, and the second flow path during the injection in the inverted state. Then, the liquid gas is disconnected from the injection mechanism unit 3 and the vaporized gas above the liquid level is communicated to the injection mechanism unit 3 through the first flow path 23. The valve means of the ejected object storage chamber 4 allows liquid to communicate with the ejection mechanism unit 3 through the first flow path 43 and air from the second flow path 44 to the ejection mechanism unit 3 during ejection in an upright state. The communication is cut off, and the liquid in the ejected object storage chamber 4 is communicated to the ejection mechanism unit 3 through the second flow path 44 during ejection in the inverted state.

本願第２の発明は、上記本願第１の発明にあって、次の構成を採る吸引式噴射器を提供する。
即ち、上記噴射ボンベ２は、上記の開閉手段２２と、上記の第１流路２３と、流路接続部と、液溜りとを備える。上記開閉手段２２は、ステムと、噴射ボンベの口を塞ぎ当該ステムの基端側を受容する受容部と、当該受容部とガス収容室とを連絡する連絡口とを備える。上記のステムは、上記の噴射機構部３へ接続されると共に、上記連絡口を閉鎖し、作動させることにより当該連絡口を開放して噴射ボンベ２内のガス収容室と噴射機構部とを連絡する。上記の第１流路２３は、噴射ボンベ２のガス収容室内に配され、基端が上記の流路接続部を介して上記の開閉手段２２に接続され、噴射器の倒立時に液化ガスの液面より上方に位置する気化したガスを、上記連絡口に向けて導く。上記の流路接続部は、上記連絡口と第１流路２３とを連絡するものであり、当該流路接続部の内部には、噴射器の倒立状態において第１流路２３の基端の直下に上記第１流路２３の基端側の開口部と対面するよう上記の液溜りが設けられている。噴射器を倒立させる際、第１流路２３内の液状のガスを上記液溜りに落とすことができ、当該液状のガスが、上記連絡口へ侵入するのを抑制する。 A second invention of the present application is the first invention of the present application, and provides a suction type injector having the following configuration.
That is, the injection cylinder 2 includes the opening / closing means 22, the first flow path 23, a flow path connection portion, and a liquid reservoir. The opening / closing means 22 includes a stem, a receiving portion that closes the mouth of the injection cylinder and receives the proximal end side of the stem, and a communication port that connects the receiving portion and the gas storage chamber. The stem is connected to the injection mechanism unit 3, and the communication port is closed and operated to open the communication port to connect the gas storage chamber in the injection cylinder 2 and the injection mechanism unit. To do. The first flow path 23 is disposed in the gas storage chamber of the injection cylinder 2 and has a base end connected to the opening / closing means 22 via the flow path connecting portion.

The flow path connection portion communicates the communication port and the first flow path 23, and the flow path connection portion has a base end of the first flow path 23 in an inverted state of the injector. The liquid reservoir is provided directly below and facing the opening on the proximal end side of the first flow path 23. When the injector is inverted, the liquid gas in the first flow path 23 can be dropped into the liquid reservoir, and the liquid gas is prevented from entering the communication port.

本願第１乃至第２の発明にあっては、表面が滑らかな物質に比して表面積の大きな多孔質部材を設けることにより、液化ガスの液状部分について、液相部分の界面を大きなものとし、気化を速やかに行うことを可能とした。ここでいう界面とは、液相から気相への転換面（気化面）をいい、上記の液面のみを指すのではない。即ち、従来液面のみを上記転換面として、気化が行われていたが、多孔質部材を設けることにより、多孔質部材の孔に巻き込まれた泡が液相から気相への転換を促すものであり、上記転換面を液状部分の内部に拡大した。 In the first and second inventions of the present application, by providing a porous member having a large surface area as compared with a material having a smooth surface, the liquid phase portion of the liquefied gas liquid portion has a large interface, Vaporization was made possible quickly. The interface here refers to a conversion surface (vaporization surface) from a liquid phase to a gas phase, and does not indicate only the above-described liquid surface. In other words, vaporization has been carried out using only the liquid surface as the conversion surface, but by providing a porous member, the bubbles entrained in the pores of the porous member promote the conversion from the liquid phase to the gas phase. And the conversion surface was enlarged inside the liquid portion.

これは、本願発明者が、水等の液体加熱時、液面からのみ気化する「蒸発」に対し、液内部から気化する「沸騰」に着目して、同様の現象を利用したものである。
即ち、上記の多孔質部材の配設は、突沸を防ぐために沸騰石を投入するのと同様の作用を得るためである。この突沸は、滑らかな容器に液体を入れて加熱すると、本来の沸点の温度になっても、沸騰が起こらず、沸点よりやや高い温度になったとき、突然に沸騰が激しく起こる現象である。沸点になった液体の内部では、内部でも蒸発（気化）が起ころうとしているが、非常に小さな蒸気の粒（気泡）ができても、それがすぐつぶれてしまうためにこのような現象が生じる。つぶれる原因は、気泡の外の液体の圧力のほうが気泡の圧力よりも少し高く、気泡は押しつぶされてしまうからである。押しつぶされないためには、気泡がある程度大きくなくてはならず、このため、表面に多数の穴があいている沸騰石を利用する。多孔性物質である沸騰石の穴の中には空気が入っており、温度が上がるにつれて孔の中の空気が膨張して空気の気泡ができる。沸点になると、その空気の気泡をめがけて、液体が蒸発し、できた気泡は、おしつぶされることなく、比較的大きな気泡となって出てくることになる。
本願発明者において、このような水やエタノールの加熱における現象を、常温下、噴射器の液化ガスのボンベ中に再現するという奇抜な発想により、本願発明を創作したものである。 This is because the present inventor uses the same phenomenon by paying attention to “boiling” which evaporates from the inside of the liquid as opposed to “evaporation” which evaporates only from the liquid surface during heating of the liquid such as water.
That is, the arrangement of the porous member described above is to obtain the same effect as that of adding boiling stones to prevent bumping. This bumping is a phenomenon in which, when a liquid is put in a smooth container and heated, boiling does not occur even when the temperature reaches the original boiling point, and suddenly vigorously occurs when the temperature becomes slightly higher than the boiling point. Evaporation (vaporization) is about to occur inside the liquid that has reached its boiling point, but even if very small vapor particles (bubbles) are formed, this phenomenon occurs because it collapses immediately. . The cause of the collapse is that the pressure of the liquid outside the bubbles is slightly higher than the pressure of the bubbles, and the bubbles are crushed. In order not to be crushed, the bubbles must be large to some extent. For this reason, a boiling stone having many holes in the surface is used. Air is contained in the hole of the boiling stone, which is a porous material, and as the temperature rises, the air in the hole expands to form air bubbles. When the boiling point is reached, the liquid evaporates over the bubbles of the air, and the generated bubbles come out as relatively large bubbles without being crushed.
The inventor of the present application has created the present invention based on the unusual idea of reproducing such a phenomenon of heating water or ethanol in a liquefied gas cylinder of an injector at room temperature.

特に、本願の各発明にあっては、上記の構成を採ることにより、噴射器を、正立のみならず倒立させて使用する場合にも、円滑な噴射が行える。 In particular, in each invention of the present application, by adopting the above-described configuration, smooth injection can be performed even when the injector is used upside down as well as upright.

Hereinafter, the configuration of each unit will be described in more detail.

先ず、上記の噴射ボンベ２について、具体的に説明する。
図２へ示す通り、上記の噴射ボンベ２の内部は、上記噴射用の液化ガスを収容するガス収容室２０である。収容する液化ガスとしては、例えば、ＤＭＥ、ＨＦＣ−１５２ａ、ＬＰＧ、弗化炭化水素を採用することができる。液化ガスは、エアゾール製品として一般的な圧力を有するものや、それ以上高圧のものでもよい。その噴射によって、後述の被噴射物収納室内の被噴射物を吸引して噴射させることができるものであれば、その種類や圧力は問わない。
液化ガスは、噴射ボンベ２のガス収容室２０において、気化した部分（気相部ｇ１）と、液状の部分（液相部ｇ２）とに分かれている。ｇ０は、当該気化した部分と液状の部分の界面を示している。
噴射ボンベ２は、図２へ示す通り、ボンベの上方に向けて開口する口２１と、当該口２１の開閉手段２２と、ガス収容室２０内に配された第１流路２３と、同じくガス収容室２０内に配された第２流路２４と、第2流路２４を開閉する弁手段２５と、流路接続部２６と、液溜り２７と、上記の多孔質部材６とを備える。
以下、上記の開閉手段２２をボンベ開閉手段２２と、第１流路２３を第１ガス流路２３と、第２流路２４を第２ガス流路２４と、弁手段２５を液弁手段２５と呼ぶ。 First, the injection cylinder 2 will be specifically described.
As shown in FIG. 2, the inside of the injection cylinder 2 is a gas storage chamber 20 that stores the liquefied gas for injection. As the liquefied gas to be accommodated, for example, DME, HFC-152a, LPG, or fluorinated hydrocarbon can be employed. The liquefied gas may have a general pressure as an aerosol product or a higher pressure. Any type or pressure may be used as long as it can suck and inject an injection target in the injection target storage chamber described later.
The liquefied gas is divided into a vaporized portion (gas phase portion g1) and a liquid portion (liquid phase portion g2) in the gas storage chamber 20 of the injection cylinder 2. g0 indicates the interface between the vaporized portion and the liquid portion.
As shown in FIG. 2, the injection cylinder 2 includes a port 21 that opens upward of the cylinder, an opening / closing means 22 for the port 21, a first flow path 23 disposed in the gas storage chamber 20, and a gas. A second flow path 24 disposed in the storage chamber 20, valve means 25 for opening and closing the second flow path 24, a flow path connection portion 26, a liquid reservoir 27, and the porous member 6 are provided.
Hereinafter, the opening / closing means 22 is the cylinder opening / closing means 22, the first flow path 23 is the first gas flow path 23, the second flow path 24 is the second gas flow path 24, and the valve means 25 is the liquid valve means 25. Call it.

上記の多孔質部材６は、図２及び図３へ示す通り、ボンベの正立状態及び倒立状態のいずれにおいても、液化ガスの液状部分ｇ２に少なくともその一部が浸されている（図２へ示す通り全体が浸されていても良い）。
多孔質部材６には、スポンジに代表される発泡ウレタン、発泡ポリエチレン、多孔質セラミック、多孔質プラスチック（多孔質ポリプロピレン、多孔質ポリエチレン）に代表される焼結部材、不織布、沸石などの沸騰石を採用することができる。
上記多孔質部材６が備える孔については、ガスの種類によって異なるものであるが、一般的には、１０〜５００μｍの径を有するものが好ましい。
但し、温度、圧力などの条件によっては、このような数値の範囲外のものであっても、実施可能である。 2 and 3, at least a part of the porous member 6 is immersed in the liquid portion g2 of the liquefied gas in both the upright state and the inverted state of the cylinder (see FIG. 2). The whole may be immersed as shown).
The porous member 6 is made of foamed urethane such as sponge, foamed polyethylene, porous ceramic, sintered member typified by porous plastic (porous polypropylene, porous polyethylene), non-woven fabric, boiling stone such as zeolite. Can be adopted.
About the hole with which the said porous member 6 is provided, although it changes with kinds of gas, generally what has a diameter of 10-500 micrometers is preferable.
However, depending on conditions such as temperature and pressure, it can be carried out even outside the range of such numerical values.

この実施の形態において、多孔質部材６は、上記の第１流路２３の表面に取り付けられている。即ち、多孔室部材６は、第１流路２３を中心として、当該第１流路２３を内包するように、第１流路２３の下端から上端にかけて設けられている。例えば、多孔質部材６にセラミックやウレタンといった定形性を有する素材を採用する場合、多孔質部材６の中央においてその上下に貫通する貫通孔を設けて、当該貫通孔に第１流路２３を嵌合するように取り付けることができる。多孔質部材６は、この他、ガス収容室２０の内周面に設けて実施することが可能である。この場合、ボンベを上下逆さまにしても（倒立させても）、常に多孔質部材６が液化ガスの液状部分に浸された状態となるよう、ガス収容室２０の上下方向の全域に渡って、多孔質部材６を配設しておくのが好ましい。多孔質部材６の固定は、接着剤を用いる他、ガス収容室２０の取り付け位置を、多孔質部材６を受容できる形状に形成して嵌め込んだり、或いはビスやネジなどの周知の冶具を用いて取り付けることができる。また、冶具としては、上記の他、紐や帯状などの、縛り付けが可能なものを採用することが可能である。
また、多孔質部材６を、上記のようにガス収容室２０内の特定位置に固定せずに、液化ガスと共にガス収容室２０内に収容するものとしても実施可能である（この場合、多孔質部材６は、ボンベの正立・倒立に伴って、液化ガスと共に、上下に移動することができる）。 In this embodiment, the porous member 6 is attached to the surface of the first flow path 23. That is, the porous chamber member 6 is provided from the lower end to the upper end of the first flow path 23 so as to include the first flow path 23 with the first flow path 23 as the center. For example, when a material having a regularity such as ceramic or urethane is adopted for the porous member 6, a through-hole penetrating vertically is provided in the center of the porous member 6, and the first flow path 23 is fitted into the through-hole. Can be attached to fit. In addition, the porous member 6 can be provided by being provided on the inner peripheral surface of the gas storage chamber 20. In this case, even if the cylinder is turned upside down (inverted), the porous member 6 is always immersed in the liquid portion of the liquefied gas over the entire area in the vertical direction of the gas storage chamber 20, It is preferable to dispose the porous member 6 in advance. For fixing the porous member 6, an adhesive is used, and the attachment position of the gas storage chamber 20 is formed in a shape that can receive the porous member 6, or a known jig such as a screw or a screw is used.

The mouth 41 of the storage quality 4 is closed (in this state, the upper end of the annular portion 48c abuts on the stem body 48a and does not pass through the blocking position).

また、このとき、図４へ示す通り、第１当接部である、環状部４８ｃの肩部４８ｄは、第１被当接部となる、隆起部１１ａの先端と当接して、上記間欠部ａ２と上記隙間ａ１とが連絡するのを遮断（シール）している。
図４へ示すように（正立状態において）、受容部４９の内周面には、上記閉鎖状態の環状部４８ｃより下方には、第３当接部となる環状部４８ｃの下端部に対して対向するように、第３被当接部となる段差４９ａが設けられている。図４に示すステム未作動の状態では、環状部４８ｃの下端（第３当接部）は、上記段差４９ａ（第３被当接部）から上方に離れている。 At this time, as shown in FIG. 4, the shoulder portion 48d of the annular portion 48c, which is the first contact portion, is in contact with the tip of the raised portion 11a, which is the first contact portion, and the intermittent portion The contact between a2 and the gap a1 is blocked (sealed).
As shown in FIG. 4 (in an upright state), the inner peripheral surface of the receiving portion 49 is below the closed annular portion 48c with respect to the lower end portion of the annular portion 48c serving as the third contact portion. A step 49a serving as a third contacted portion is provided so as to face each other. 4, the lower end (third contact portion) of the annular portion 48c is spaced upward from the step 49a (third contacted portion).

図５へ示すように、ステム４８を作動させ（この実施の形態では下方に作動させ）、延設部４８ｂを下方に移動させると、環状部４８ｃの内肩部４８ｅ（第２当接部）から、延設部４８ｂの外肩部４８ｆ（第２被当接部）が下方に離れて、孔４８ｇ，４８ｇが環状部４８ｃから開放される。これにて、連絡口４１ａからステム４８内部へ被噴射物Ｗ１が移動可能となる。 As shown in FIG. 5, when the stem 48 is operated (actuated downward in this embodiment) and the extending portion 48b is moved downward, the inner shoulder portion 48e (second contact portion) of the annular portion 48c. Thus, the outer shoulder portion 48f (second contacted portion) of the extending portion 48b is moved downward, and the holes 48g and 48g are opened from the annular portion 48c. Thus, the injection target W1 can move from the communication port 41a into the stem 48.

更にステム４８を作動させ続けると、図６及び図７へ示すように、ステム本体４８ａの下端（延設部４８ｂがないとした場合の基端）に押されて、環状部４８ｃも下方に移動する（最終的に、環状部４８ｃの下端（第３当接部）は、上記段差４９ａ（第３被当接部）へ当接して下方への移動を停止する）。これによって、上記の環状部４８ｃの肩部４８ｄ（第１当接部）は、隆起部１１ａ（第１被当接部）の先端から離れ、上記間欠部ａ２と上記隙間ａ１とが連絡し、ケーシング１外部から被噴射物収納室４内に空気を導入することができる（図７）。そして、図６に示す通り、前述の被噴射物Ｗ１の排出が行えるのである。
尚、図８に示す通り、倒立させて使用する場合であっても、液漏れが生じないように、上記空気導入の通路（間欠部ａ２と上記隙間ａ１）を、表面張力により液体が通り抜けられない幅に設定しておけばよい。 When the stem 48 is further operated, as shown in FIGS. 6 and 7, it is pushed by the lower end of the stem main body 48a (the base end when there is no extending portion 48b), and the annular portion 48c also moves downward. (Finally, the lower end (third contact portion) of the annular portion 48c contacts the step 49a (third contacted portion) and stops moving downward). Thereby, the shoulder portion 48d (first contact portion) of the annular portion 48c is separated from the tip of the raised portion 11a (first contact portion), and the intermittent portion a2 and the gap a1 communicate with each other. Air can be introduced into the ejected object storage chamber 4 from the outside of the casing 1 (FIG. 7). And as shown in FIG. 6, discharge | emission of the above-mentioned to-be-injected object W1 can be performed.
As shown in FIG. 8, even when the apparatus is used upside down, the liquid can pass through the air introduction passage (intermittent part a2 and the gap a1) by the surface tension so that the liquid does not leak. It should be set to a width that does not.

使用後、被噴射物Ｗ１吐出後、ステム４８へ加えられた力が解除されることにより、付勢手段４９ｂの付勢により、延設部４８ｂは、図６に示す状態から、（上方への）復帰を開始する。図示はしないが、当該復帰の途中、延設部４８ｂの外肩部４８ｆ（第２被当接部）が、環状部４９ｃの内肩部４８ｅ（第２当接部）へ再び当接し、環状部４８ｃは、延設部４８ｂによって、作動前の位置まで（上方に向けて）押し戻される。そして、上記の各部が、図４の状態に復帰するのである。 After use, after the ejected object W1 is discharged, the force applied to the stem 48 is released, and the urging means 49b urges the extending portion 48b from the state shown in FIG. ) Start recovery. Although not shown, during the return, the outer shoulder 48f (second contacted portion) of the extended portion 48b again comes into contact with the inner shoulder 48e (second contacting portion) of the annular portion 49c, thereby The part 48c is pushed back to the position before the operation (upward) by the extending part 48b. And each said part returns to the state of FIG.

次に、上記の噴射機構部３について説明する。
図１へ示す通り、噴射機構部３は、ケーシング１の蓋体１１に設けられており、噴射ボンベ２と被噴射物収納室４のステム２８，４８が、夫々、接続されている。具体的には、噴射機構部３は、ケーシング１の蓋体１１に設けられた支持部３１と、当該支持部３１に軸止された作動本体３２とを備える。作動本体３２は、軸３３を中心として、回動可能に、支持部３１に取り付けられている。作動本体３２は、噴射部３４と、ボンベ接続部３５と、収納室接続部３６と、指掛け部３７とを備える。ボンベ接続部３５は、噴射ボンベ２の上記ステム２８が接続される。収納室接続部３６は、被噴射物収納部４の上記ステム４８が接続される。噴射部３４は、ガスを噴射するノズル部３４ａと、ノズル部３４ａの噴射方向（ノズル部３４ａの前方）に設けられた負圧発生室３４ｂと、負圧発生室３４ｂに設けられた噴射口３４ｃとを備える。上記のボンベ接続部３５は、上記ノズル部３４ａに連絡する。また、上記の負圧発生室３４ｂは、収納室接続部３６に連絡する。 Next, the injection mechanism unit 3 will be described.
As shown in FIG. 1, the injection mechanism unit 3 is provided on the lid 11 of the casing 1, and the injection cylinder 2 and the stems 28 and 48 of the injection object storage chamber 4 are connected to each other. Specifically, the injection mechanism unit 3 includes a support part 31 provided on the lid body 11 of the casing 1 and an operation main body 32 pivotally fixed to the support part 31. The operating body 32 is attached to the support portion 31 so as to be rotatable about a shaft 33. The operation main body 32 includes an injection unit 34, a cylinder connection unit 35, a storage chamber connection unit 36, and a finger hook unit 37. The cylinder connecting portion 35 is connected to the stem 28 of the injection cylinder 2. The storage chamber connection portion 36 is connected to the stem 48 of the injection target storage portion 4. The injection unit 34 includes a nozzle unit 34a for injecting gas, a negative pressure generation chamber 34b provided in the injection direction of the nozzle unit 34a (in front of the nozzle unit 34a), and an injection port 34c provided in the negative pressure generation chamber 34b. With. The cylinder connecting portion 35 communicates with the nozzle portion 34a. Further, the negative pressure generating chamber 34 b communicates with the storage chamber connecting portion 36.

噴射器の使用時、上記の指掛け部３７へ指を掛けて引くことにより、軸３３を中心として、下方の噴射ボンベ２及び被噴射物収納室４側に、作動本体３２を回動させることができる。この回動によって、ボンベ接続部３５に接続された噴射ボンベ２のステム２８と、収納室接続部３６に接続された被噴射物収納部４のステム４８とを同時に作動することができる。ボンベ接続部３５のステム２８の作動により、気化したガスが、ノズル部３４ａに送られ、ノズル部３４ａから負圧発生室３４ｂ内を経て、噴射口３４ｃから外部へ噴射される。このガスの噴射により、負圧発生室３４ｂ内には負圧が発生し、当該負圧によって、ステム４８の作動によって、開放された被噴射物収納部４内の被噴射物Ｗ１が負圧発生室３４ｂ内に吸い上げられ、上記ガスと共に噴射口３４ｃから外部へ噴射される。 When the injector is used, the operation main body 32 can be rotated toward the lower injection cylinder 2 and the object storage chamber 4 around the shaft 33 by hooking and pulling a finger on the finger-holding portion 37. it can. By this rotation, the stem 28 of the injection cylinder 2 connected to the cylinder connection part 35 and the stem 48 of the injection object storage part 4 connected to the storage chamber connection part 36 can be operated simultaneously. By the operation of the stem 28 of the cylinder connection part 35, the vaporized gas is sent to the nozzle part 34a, and is injected from the nozzle part 34a to the outside through the negative pressure generating chamber 34b. By this gas injection, a negative pressure is generated in the negative pressure generating chamber 34b, and the negative object generates a negative pressure by the operation of the stem 48 in the object W1 that is opened in the object storage part 4 opened. The air is sucked into the chamber 34b and is ejected together with the gas from the ejection port 34c.

上記の実施の形態において、ケーシング１は、天部となる蓋体１１にボンベ収納部５を取り付けて、被噴射物収納室４内に、ボンベ収納部５を配置するものとした。この他、図示はしないが、被噴射物収納室４内にボンベ収納部５を配置するのではなく、ケーシング１自体をドーナツ状に形成して（当然内部の被噴射物収納室４もドーナツ状となる。）、中央の中空部分に、噴射ボンベ２を収納するようにしても実施可能である。またハウジング１は、上記以外の形状に変更が可能である。
噴射ボンベ２の表面が直接被噴射物収納室４内の被噴射物と接触しても構わない場合、上記と異なり、噴射ボンベ２は、直接、被噴射物収納室４内に配置されるものであっても実施可能である。例えば、噴射ボンベ２自身を樹脂製としても実施可能である。
上記の噴射機構部３については、トリガー型、即ち、指掛け部３７を引くことにより作動本体３２が軸３３を中心に回動して、両ステム２８，４８を作動させるものであった。この他、作動本体３２は、軸３３中心に回動するのではなく、即ち、指掛け部３７を引くのではなく（指掛け部３７を持たず）、上方から下方に押し下げることによって、両ステム２８，４８を下方に作動させる形式のものを採用して実施することも可能である。
噴射ボンベ２や被噴射物収納室４の開閉手段や弁手段についても、上記の実施の形態のものに限定するものではなく、周知の他の形態を採るものであっても実施可能である。 In the above-described embodiment, the casing 1 is configured such that the cylinder storage portion 5 is attached to the lid body 11 serving as the top portion, and the cylinder storage portion 5 is disposed in the injection object storage chamber 4. In addition, although not shown, the cylinder storage portion 5 is not disposed in the ejected object storage chamber 4, but the casing 1 itself is formed in a donut shape (of course, the inner ejected object storage chamber 4 is also a donut shape). It is also possible to implement the method by storing the injection cylinder 2 in the central hollow portion. The housing 1 can be changed to a shape other than the above.
When the surface of the injection cylinder 2 may be in direct contact with the injection object in the injection object storage chamber 4, unlike the above, the injection cylinder 2 is directly arranged in the injection object storage chamber 4. Even so, it can be implemented. For example, the injection cylinder 2 itself can be made of resin.
The above-described injection mechanism 3 is a trigger type, that is, the operation main body 32 is rotated about the shaft 33 by pulling the finger hanging portion 37 to operate both the stems 28 and 48. In addition, the operation main body 32 does not rotate around the shaft 33, that is, does not pull the finger hanger 37 (without the finger hanger 37), but pushes it downward from above, so that both stems 28, It is also possible to adopt a type in which 48 is operated downward.
The opening / closing means and the valve means of the injection cylinder 2 and the injection object storage chamber 4 are not limited to those of the above-described embodiment, and may be implemented even if other known forms are adopted.

本願発明に係る吸引式噴射器によれば、液化ガスの噴射において従来問題となった、液相部において瞬時に気化が起こらず噴霧力が落ちる、即ち、見かけ上、数秒で、０．２〜０．３ＭＰａ
程の圧力降下が起こるものであったが、上記の多孔質部材６の配設により、このような圧力降下を改善した。
例えば、液化ガスとして、ＨＦＣ−１５２ａを採用した場合、噴射圧Ｐの０．５ＭＰａから０．２５ＭＰａへの降下（半減）に、３０秒程度の時間を確保することが可能となった。
この圧力降下について、本願発明に係る噴射器の試験結果を以下に示す。
１）〜４）は、多孔質部材／噴射直後から噴射の勢いに変化が生じるまでの時間を示している。
１）なし／２〜３秒
２）スポンジ／１５〜２０秒
３）焼結部材／１５〜２０秒
４）沸石／１０〜１５秒

上記２）のスポンジとしては、０．１５ｇ／８ｃｍ3（一辺２ｃｍの立方体について重さ０．１５ｇ）のものを、採用した。また、３）の焼結部材としては、ポリエチレン粉末を焼結させたものを採用した。但し、ポリエチレン粉末を焼結させた焼結部材を採用しても、ポリエチレン粉末を焼結させた焼結部材と同様の結果であった。また、４）の沸石については、二酸化珪素の鉱物を採用した。 According to the suction type injector according to the present invention, the spraying force is lowered without instantaneously vaporizing in the liquid phase portion, which has been a problem in the conventional liquefied gas injection, that is, apparently within a few seconds, 0.2 to 0.3 MPa
Although such a pressure drop occurred, the pressure drop was improved by the arrangement of the porous member 6 described above.
For example, when HFC-152a is employed as the liquefied gas, it is possible to secure a time of about 30 seconds for the drop (halved) of the injection pressure P from 0.5 MPa to 0.25 MPa.
Regarding this pressure drop, the test results of the injector according to the present invention are shown below.
1) to 4) indicate the time from the porous member / immediately after the injection until the change in the injection momentum occurs.
1) None / 2 to 3 seconds 2) Sponge / 15 to 20 seconds 3) Sintered member / 15 to 20 seconds 4) Zeolite / 10 to 15 seconds

As the sponge of 2), 0.15 g / 8 cm @ 3 (weight of 0.15 g for a cube having a side of 2 cm) was used. Further, as the sintered member of 3), a sintered material of polyethylene powder was adopted. However, even when a sintered member obtained by sintering polyethylene powder was used, the result was the same as that obtained by sintering the polyethylene powder. For the zeolite 4), silicon dioxide mineral was used.

上記の通り、多孔質部材を採用した何れの場合２）〜４）も、噴射の変化が見られるまで１０秒以上を要するものに改善されている。これから、噴射の変化が２〜３秒で生じる多孔質部材を用いない場合１）と比して、大きな改善がなされていることが分かる。 As described above, in any case 2) to 4) in which the porous member is employed, the improvement is required to take 10 seconds or more until a change in injection is observed. From this, it can be seen that a significant improvement has been made as compared to 1) in which the porous member in which the change in injection occurs in 2 to 3 seconds is not used.

また、液化ガスのボンベと、被噴射物収納部とでは、排出する必要があるのは、一方は気化ガス、他方は液体と異なる。本願発明に係る噴射器では、正立使用時、倒立使用時の何れにおいても、そのような排出を同時に確実に行うことができ、ベンチュリー即ち、吸引式の噴射器において、簡単な構造で、被噴射物の噴射を確実に行うことを可能とした。 Further, in the cylinder of liquefied gas and the object storage section, it is necessary to discharge one from the vaporized gas and the other from the liquid. In the injector according to the present invention, such discharge can be performed at the same time in both the upright use and the inverted use, and the venturi, that is, the suction type injector, can be covered with a simple structure. It was made possible to reliably perform the injection of the projectile.
