 ところで、切屑等が設備に強固に付着したり、或いは、粉塵が多量に発生するような作業環境においては、上述の如きエア吸込吹出ツールの吸込量及び吹出量を多くしたいという要望がある。 By the way, in a work environment where chips or the like are firmly attached to the equipment or a large amount of dust is generated, there is a demand for increasing the suction amount and the blow amount of the air suction blow tool as described above.
 これに対応するために、エア吸込吹出ツールに導入する圧縮エアの流量を単に多くすることが考えられるが、これでは、圧縮エアを作り出すコンプレッサーの負荷が高くなって無駄にエネルギーを消費することになってしまう。 In order to cope with this, it is conceivable to simply increase the flow rate of the compressed air introduced into the air suction / blowing tool. However, this increases the load on the compressor that generates the compressed air and wastes energy. turn into.
 本発明は、斯かる点に鑑みてなされたものであり、その目的とするところは、無駄なエネルギーを消費することなく吸込量及び吹出量を多くすることができるエア吸込吹出ツールを提供することにある。 This invention is made in view of such a point, The place made into the objective is providing the air suction blowing tool which can increase suction amount and blowing amount, without consuming useless energy. It is in.
 上記の目的を達成するために、本発明は、筒体における第2エア通路への圧縮エアの導入の仕方に工夫を凝らしたことを特徴とする。 In order to achieve the above object, the present invention is characterized in that the method of introducing compressed air into the second air passage in the cylinder has been devised.
 具体的には、エアが流通可能な第1エア通路を筒中心軸に沿って有する筒体と、該筒体の筒中心軸方向一方側に設けられ、上記第1エア通路に開口するエア吸込口と、上記筒体の筒中心軸方向他方側に設けられ、上記第1エア通路に開口するエア吹出口と、上記筒体の中途部に設けられ、且つ、上記筒体の周方向に環状に延び、上記筒体外周面の一箇所に圧縮エア入口が、上記第1エア通路内周面に周方向に延びる環状の圧縮エア出口がそれぞれ形成された第2エア通路とを備え、該第2エア通路に上記圧縮エア入口から導入した圧縮エアを上記圧縮エア出口から上記第1エア通路のエア吹出口側に向かうよう吐出させて上記第1エア通路のエア吸込口側を負圧にすることにより上記第1エア通路にエア流れを発生させ、上記エア吸込口から上記第1エア通路にエアを吸い込んで上記エア吹出口からエアを吹き出すエア吸込吹出ツールを対象とし、次のような解決手段を講じた。 Specifically, a cylinder having a first air passage through which the air can flow along the cylinder central axis, and an air suction provided on one side of the cylinder in the cylinder central axis direction and opening to the first air passage. An opening, an air outlet provided on the other side in the cylinder central axis direction of the cylinder, and opened to the first air passage; provided in the middle of the cylinder; and annular in the circumferential direction of the cylinder And a second air passage having a compressed air inlet formed at one location on the outer peripheral surface of the cylindrical body and an annular compressed air outlet extending in the circumferential direction on the inner peripheral surface of the first air passage. Compressed air introduced from the compressed air inlet into the two air passages is discharged from the compressed air outlet toward the air outlet side of the first air passage so that the air suction port side of the first air passage becomes negative pressure. The air flow is generated in the first air passage, and the air suction port Intended for air suction blowing tool for blowing air from the air outlet sucks air in the first air passage, it took solving means as follows.
 すなわち、第1の発明では、上記圧縮エア入口は、上記第2エア通路に対して圧縮エアを上記筒体の周方向に沿って導入するよう構成されていることを特徴とする。 That is, in the first invention, the compressed air inlet is configured to introduce compressed air into the second air passage along the circumferential direction of the cylindrical body.
 第2の発明では、第1の発明において、上記筒体は、上記エア吸込口を一端に有し、且つ、外側方に突出するとともに周方向に延びる環状突条部が中途部に形成された第1筒部材と、上記エア吹出口を一端に有し、且つ、外側方に膨らむとともに周方向に延びる環状膨出部が他端側に形成され、該環状膨出部の一箇所に上記圧縮エア入口を有する第2筒部材とを備え、上記第1筒部材におけるエア吸込口の反対側を上記第2筒部材の内部に上記環状膨出部側から挿入して当該環状膨出部の開口側と上記環状突条部とを嵌合させることにより、上記第1筒部材におけるエア吸込口の反対側外周面と上記環状膨出部の内周面との間に上記第2エア通路が形成されるとともに、上記第1筒部材におけるエア吸込口の反対側端部と上記環状膨出部に連続する上記エア吹出口側の上記第2筒部材内周面との間に上記圧縮エア出口が形成されるよう構成されていることを特徴とする。 In a second invention, in the first invention, the cylindrical body has the air suction port at one end, and an annular ridge portion that protrudes outward and extends in the circumferential direction is formed in the middle portion. An annular bulging portion that has the first tube member and the air outlet at one end and bulges outward and extends in the circumferential direction is formed on the other end side, and the compression is performed at one place of the annular bulging portion. A second cylindrical member having an air inlet, and an opening of the annular bulging portion is formed by inserting the opposite side of the air suction port of the first cylindrical member into the second cylindrical member from the annular bulging portion side. The second air passage is formed between the outer peripheral surface on the opposite side of the air suction port of the first tubular member and the inner peripheral surface of the annular bulging portion by fitting the side and the annular ridge portion. And at the opposite end of the air suction port and the annular bulge in the first tubular member Characterized in that it is configured to the compressed air outlet is formed between the air outlet side of the second cylindrical member inner peripheral surface to continue.
 第3の発明では、第2の発明において、上記第1筒部材における上記エア吸込口の反対側は、端部に行くにつれて次第に厚みが薄くなる尖鋭な形状をなしていることを特徴とする。 The third invention is characterized in that, in the second invention, the opposite side of the air suction port in the first cylindrical member has a sharp shape that gradually decreases in thickness toward the end.
 第4の発明では、第2又は第3の発明において、上記第2筒部材の上記環状膨出部に連続するエア吹出口側の内周面には、上記エア吹出口に向かうにつれて次第に縮径しながら延びる縮径面と、該縮径面の延出端から上記エア吹出口に向かって同一径で延びる同径面と、該同径面の延出端から上記エア吹出口まで次第に拡径しながら延びる拡径面とが形成されていることを特徴とする。 According to a fourth invention, in the second or third invention, the inner peripheral surface of the second cylindrical member on the air outlet side continuous with the annular bulging portion is gradually reduced in diameter toward the air outlet. A diameter-reducing surface that extends while extending from the extending end of the reduced-diameter surface to the air outlet, and a diameter that gradually increases from the extending end of the same-diameter surface to the air outlet. An enlarged-diameter surface extending while being formed.
 第1の発明では、圧縮エア入口から第2エア通路に導入された圧縮エアは、第2エア通路をその内周面に沿って筒体の周方向一方側にのみ流れるので、筒中心軸周りに旋回しながら圧縮エア出口まで流れる。したがって、第2エア通路に導入された圧縮エアが筒体の周方向の一方側と他方側とに分かれて流れるとともに所定の位置で合流するといったことがなくなり、第2エア通路における圧縮エアの流れが乱れなくなってエネルギー損失が少なくなるので、圧縮エアの流量を増やすことなく第1エア通路を流通するエアの体積流量を増やしてエア吸込口から吸込されるエアの吸込量及びエア吹出口から吹き出されるエアの吹出量を多くすることができる。 In the first invention, the compressed air introduced into the second air passage from the compressed air inlet flows only on one side in the circumferential direction of the cylinder along the inner peripheral surface of the second air passage. It flows to the compressed air outlet while turning. Therefore, the compressed air introduced into the second air passage does not flow separately on one side and the other side in the circumferential direction of the cylindrical body and does not merge at a predetermined position, and the flow of the compressed air in the second air passage. Since the air flow is not disturbed and energy loss is reduced, the volumetric flow rate of the air flowing through the first air passage is increased without increasing the flow rate of the compressed air, and the amount of air sucked from the air suction port and blown out from the air outlet The amount of air blown out can be increased.
 第2の発明では、エア吸込吹出ツールを構成する部品が2つしかないので、組立時間が短くなって組立コストを下げることができる。 In the second invention, since there are only two parts constituting the air suction / blowing tool, the assembling time can be shortened and the assembling cost can be reduced.
 第3の発明では、第1エア通路を流通するエアと圧縮エア出口から第1エア通路に吐出される圧縮エアとがスムーズに合流するようになるので、圧縮エア出口周りにおけるエネルギー損失を低下させて第1エア通路のエアの体積流量をさらに増やすことができる。 In the third aspect of the invention, the air flowing through the first air passage and the compressed air discharged from the compressed air outlet to the first air passage are smoothly joined together, thereby reducing energy loss around the compressed air outlet. Thus, the volume flow rate of the air in the first air passage can be further increased.
 第4の発明では、第1エア通路のエア吹出口側においてその他の部分よりも断面積の小さい部分が形成されるので、当該部分において通過するエアの流速が速くなって第1エア通路のエア吸込口側の負圧が高く維持されるようになる。したがって、エア吸込吹出ツールのエア吸込力及びエア吹出力をさらに高めることができる。 In the fourth aspect of the invention, since a portion having a smaller cross-sectional area than the other portions is formed on the air outlet side of the first air passage, the flow velocity of air passing through the portion is increased, and the air in the first air passage is increased. The negative pressure on the inlet side is maintained high. Therefore, the air suction force and the air blowing output of the air suction blowing tool can be further increased.

 上記第1筒部材3の一端開口は、上記エア吸込口2bを構成している。 The one end opening of the first cylindrical member 3 constitutes the air suction port 2b.
 上記第1筒部材3の中途部には、外側方に突出するとともに周方向に沿って延びる環状突条部3aが形成され、該環状突条部3aの外周面には、雄ネジ(図示せず)が刻まれている。 An annular ridge 3a that protrudes outward and extends in the circumferential direction is formed in the middle portion of the first cylindrical member 3, and a male screw (not shown) is formed on the outer peripheral surface of the annular ridge 3a. ) Is engraved.
 上記第1筒部材3の上記環状突条部3aより上記エア吸込口2bから遠い側の外周面3bは、上記環状突条部3aより上記エア吸込口2bに近い側の外周面3cに比べて小径であり、上記エア吸込口2bから離れるにつれて次第に縮径する形状をなしている。 The outer peripheral surface 3b of the first tube member 3 on the side farther from the air suction port 2b than the annular ridge portion 3a is compared to the outer peripheral surface 3c on the side closer to the air suction port 2b than the annular ridge portion 3a. It has a small diameter, and has a shape that gradually decreases as the distance from the air suction port 2b increases.
 一方、上記第1筒部材3内周面の上記エア吸込口2b側半分は、当該エア吸込口2bから遠ざかるにつれて次第に縮径する一方、上記第1筒部材3内周面の上記エア吸込口2bの反対側半分は、同一径をなしている。 On the other hand, the half of the inner peripheral surface of the first cylindrical member 3 on the side of the air suction port 2b gradually decreases in diameter as the distance from the air suction port 2b increases, while the air suction port 2b of the inner peripheral surface of the first cylindrical member 3 increases. The opposite half has the same diameter.
 そして、上記第1筒部材3における上記エア吸込口2bの反対側は、端部に行くにつれて次第に厚みが薄くなる尖鋭な形状をなしている。 And the opposite side of the air inlet 2b in the first cylindrical member 3 has a sharp shape that gradually decreases in thickness toward the end.
 上記第2筒部材4の一端開口は、上記エア吹出口2cを構成している。 The one end opening of the second cylindrical member 4 constitutes the air outlet 2c.
 上記第2筒部材4の他端側には、外側方に段差状に膨出するとともに周方向に延びる環状膨出部4aが形成され、該環状膨出部4aの内周面には雌ネジ(図示せず)が刻まれている。 On the other end side of the second cylindrical member 4, an annular bulging portion 4a that bulges outward in a step shape and extends in the circumferential direction is formed, and an internal thread is formed on the inner peripheral surface of the annular bulging portion 4a. (Not shown) is engraved.
 上記環状膨出部4aの外周面には、外側方に突出するとともに周方向に半周に亘って延びる補強部4bが設けられ、該補強部4bの突出側には、互いに直交する直交面4cが一対形成されている。 On the outer peripheral surface of the annular bulging portion 4a, there is provided a reinforcing portion 4b that protrudes outward and extends half a circumference in the circumferential direction, and orthogonal surfaces 4c that are orthogonal to each other are provided on the protruding side of the reinforcing portion 4b. A pair is formed.
 上記環状膨出部4aには、図4に示すように、一方の直交面4cに開口するとともに上記筒体2の周方向に沿って直線状に延びる圧縮エア入口5aが形成されている。 As shown in FIG. 4, the annular bulging portion 4 a is formed with a compressed air inlet 5 a that opens in one orthogonal surface 4 c and extends linearly along the circumferential direction of the cylindrical body 2.
 すなわち、上記圧縮エア入口5aは、上記環状膨出部4aの一箇所に設けられ、第2筒部材の筒中心軸方向から見て、環状膨出部4aの内周面に沿う方向に延びている。 That is, the compressed air inlet 5a is provided at one location of the annular bulging portion 4a and extends in a direction along the inner peripheral surface of the annular bulging portion 4a when viewed from the cylinder central axis direction of the second cylinder member. Yes.
 上記第2筒部材4の上記環状膨出部4aに連続するエア吹出口2c側の内周面には、図3に示すように、上記エア吹出口2cに向かうにつれて次第に縮径しながら延びる縮径面4dが形成されている。 As shown in FIG. 3, the inner peripheral surface of the second cylindrical member 4 on the side of the air outlet 2c that is continuous with the annular bulging portion 4a is contracted while gradually decreasing in diameter toward the air outlet 2c. A radial surface 4d is formed.
 また、該縮径面4dのエア吹出口2c側には、上記縮径面4dの延出端から上記エア吹出口2cに向かって同一径で延びる同径面4eが形成されている。 Further, on the air outlet 2c side of the reduced diameter surface 4d, a same diameter surface 4e extending from the extending end of the reduced diameter surface 4d to the air outlet 2c with the same diameter is formed.
 さらに、該同径面4eのエア吹出口2c側には、上記同径面4eの延出端から上記エア吹出口2cまで次第に拡径しながら延びる拡径面4fが形成されている。 Further, on the side of the air outlet 2c of the same diameter surface 4e, an enlarged diameter surface 4f extending while gradually expanding from the extending end of the same diameter surface 4e to the air outlet 2c is formed.
 そして、上記エア吸込吹出ツール1は、上記第1筒部材3における上記エア吸込口2bの反対側(外周面3b側)を上記第2筒部材4に上記環状膨出部4a側から挿入して当該環状膨出部4aの開口側と上記環状突条部3aとを螺合により互いに嵌合させることで組み立てられ、上記第1筒部材3における上記エア吸込口2bの反対側外周面3bと上記環状膨出部4a内周面との間に第2エア通路5が形成されるとともに、上記第1筒部材3における上記エア吸込口2bの反対側の端部と上記環状膨出部4aに連続する上記エア吹出口2c側の上記第2筒部材4内周面(縮径面4d)との間に圧縮エア出口5bが形成されるよう構成されている。 And the said air suction blowing tool 1 inserts the opposite side (outer peripheral surface 3b side) of the said air suction inlet 2b in the said 1st cylinder member 3 in the said 2nd cylinder member 4 from the said annular bulging part 4a side. The opening side of the annular bulging portion 4a and the annular ridge portion 3a are assembled together by screwing together, and the outer peripheral surface 3b opposite to the air suction port 2b in the first cylindrical member 3 and the above-mentioned A second air passage 5 is formed between the inner peripheral surface of the annular bulging portion 4a and is continuous with the end portion of the first cylindrical member 3 opposite to the air suction port 2b and the annular bulging portion 4a. A compressed air outlet 5b is formed between the inner peripheral surface (reduced diameter surface 4d) of the second cylindrical member 4 on the air outlet 2c side.
 つまり、上記筒体2の中途部には、上記筒体2の周方向に環状に延びる第2エア通路5が設けられている。また、上記圧縮エア入口5aは、上記筒体2の外周面の一箇所に設けられ、上記圧縮エア出口5bは、上記筒体2内周面に周方向に延びる環状に設けられている。 That is, the second air passage 5 extending annularly in the circumferential direction of the cylinder 2 is provided in the middle of the cylinder 2. The compressed air inlet 5a is provided at one place on the outer peripheral surface of the cylindrical body 2, and the compressed air outlet 5b is provided on the inner peripheral surface of the cylindrical body 2 in an annular shape extending in the circumferential direction.
 また、第1筒部材3と第2筒部材4とが組み立てられた際、上記縮径面4dと上記第1筒部材3内周面とは面一となるよう構成されている。 Further, when the first cylindrical member 3 and the second cylindrical member 4 are assembled, the reduced diameter surface 4d and the inner peripheral surface of the first cylindrical member 3 are configured to be flush with each other.
 そして、上記エア吸込吹出ツール1は、上記第2エア通路5に上記圧縮エア入口5aから導入した圧縮エアを上記圧縮エア出口5bから上記第1エア通路2aのエア吹出口2c側に向かうよう吐出させて上記第1エア通路2aのエア吸込口2b側を負圧にすることにより、上記第1エア通路2aにエア流れF1を発生させ、上記エア吸込口2bから上記第1エア通路2aにエアを吸い込んで(X1方向)上記エア吹出口2cからエアを吹き出す(X2方向)ようになっている。 The air suction / blowing tool 1 discharges the compressed air introduced from the compressed air inlet 5a into the second air passage 5 from the compressed air outlet 5b toward the air outlet 2c of the first air passage 2a. By making negative pressure on the air suction port 2b side of the first air passage 2a, an air flow F1 is generated in the first air passage 2a, and air flows from the air suction port 2b to the first air passage 2a. (X1 direction) and air is blown out from the air outlet 2c (X2 direction).
 次に、本発明の実施形態に係るエア吸込吹出ツール1及び図5(a),(b)に示す従来型のエア吸込吹出ツール10を用いて実験した結果について説明する。 Next, the results of experiments using the air suction blow tool 1 according to the embodiment of the present invention and the conventional air suction blow tool 10 shown in FIGS. 5A and 5B will be described.
 尚、エア吸込吹出ツール10は、上記エア吸込吹出ツール1を実験用に改造したものであり、圧縮エア入口5aの位置がエア吸込吹出ツール1と異なるだけでその他の大部分はエア吸込吹出ツール1と略同じであるため、同一部分には同一符号を付している。 Note that the air suction blow tool 10 is a modification of the air suction blow tool 1 for experiments. The position of the compressed air inlet 5a is different from the air suction blow tool 1, and most of the other parts are the air suction blow tool. Since it is substantially the same as 1, the same symbol is attached to the same part.
 すなわち、エア吸込吹出ツール10の圧縮エア入口5aは、図5(b)に示すように、第2筒部材の筒中心軸方向から見て筒中心軸に向かって真っ直ぐに延びている。 That is, as shown in FIG. 5B, the compressed air inlet 5a of the air suction / blowing tool 10 extends straight toward the cylinder center axis when viewed from the cylinder center axis direction of the second cylinder member.
 図6(a)は、どれくらいの重さの錘Wを上記エア吸込吹出ツール1,10がその吸込力によって持ち上げられるかを調査する実験方法を示している。具体的には、圧縮エアの供給量を350L/mにして10gずつ重さを変化させた錘Wを各エア吸込吹出ツール1,10によって5秒以上持ち上げることがでるか否かを調査した。 FIG. 6 (a) shows an experimental method for investigating how much weight W the air suction blowing tools 1 and 10 are lifted by the suction force. Specifically, it was investigated whether or not the weight W, the weight of which was changed by 10 g when the supply amount of compressed air was 350 L / m, could be lifted by each of the air suction and blowing tools 1 and 10 for 5 seconds or more.
 図6(b)の結果から判るように、エア吸込吹出ツール1の方が従来型のエア吸込吹出ツール10より90g重い錘Wを持ち上げることができ、約24%性能が高くなっていることを確認できた。 As can be seen from the result of FIG. 6B, the air suction blow tool 1 can lift the weight W that is 90 g heavier than the conventional air suction blow tool 10 and is about 24% higher in performance. It could be confirmed.
 これは、従来型のエア吸込吹出ツール10の場合、図5(b)に示すように、圧縮エア入口5aから第2エア通路5に導入された圧縮エアが筒体2の周方向の一方側(Z1方向)と他方側(Z2方向)とに分かれて流れるとともに所定の位置で合流することで第2エア通路5における圧縮エアの流れが乱れるからと考えられる。第2エア通路5における圧縮エアの流れが乱れると、エネルギー損失が大きくなってしまい、ひいては、第1エア通路2aを流通するエアの体積流量が減ってしまう。 In the case of the conventional air suction / blowing tool 10, this is because the compressed air introduced into the second air passage 5 from the compressed air inlet 5 a is one side in the circumferential direction of the cylindrical body 2, as shown in FIG. It is considered that the flow of compressed air in the second air passage 5 is disturbed by flowing separately (Z1 direction) and the other side (Z2 direction) and merging at a predetermined position. When the flow of the compressed air in the second air passage 5 is disturbed, the energy loss increases, and as a result, the volume flow rate of the air flowing through the first air passage 2a decreases.
 これに対し、本願の実施形態のエア吸込吹出ツール1の場合、図4に示すように、圧縮エア入口5aから第2エア通路5に導入された圧縮エアが第2エア通路5をその内周面に沿って筒体2の周方向の一方側(Y1方向)にのみ流れるので、筒中心軸周りに旋回しながら圧縮エア出口5bまで流れるようになる。したがって、本願発明の実施形態によると、第2エア通路5における圧縮エアの流れが乱れなくなってエネルギー損失が少なくなるので、圧縮エアの流量を増やすことなく第1エア通路2aを流通するエアの体積流量を増やしてエア吸込口2bから吸込されるエアの吸込量及びエア吹出口2cから吹き出されるエアの吹出量を多くすることができる。 On the other hand, in the case of the air suction / blowout tool 1 of the embodiment of the present application, as shown in FIG. 4, the compressed air introduced from the compressed air inlet 5 a to the second air passage 5 passes through the inner periphery of the second air passage 5. Since it flows only to one side (Y1 direction) in the circumferential direction of the cylinder 2 along the surface, it flows to the compressed air outlet 5b while turning around the cylinder center axis. Therefore, according to the embodiment of the present invention, the flow of compressed air in the second air passage 5 is not disturbed and energy loss is reduced, so the volume of air flowing through the first air passage 2a without increasing the flow rate of the compressed air. By increasing the flow rate, it is possible to increase the amount of air sucked from the air suction port 2b and the amount of air blown from the air outlet 2c.
 また、エア吸込吹出ツール1を構成する部品が2つしかないので、組立時間が短くなって組立コストを下げることができる。 Also, since there are only two parts constituting the air suction / blowing tool 1, the assembling time can be shortened and the assembling cost can be reduced.
 さらに、第1筒部材3における上記エア吸込口2bの反対側は、端部に行くにつれて次第に厚みが薄くなる尖鋭な形状をなしているので、第1エア通路2aを流通するエアと圧縮エア出口5bから第1エア通路2aに吐出される圧縮エアとがスムーズに合流するようになり、圧縮エア出口5b周りにおけるエネルギー損失を低下させて第1エア通路2aのエアの体積流量をさらに増やすことができる。 Further, since the opposite side of the air suction port 2b in the first cylindrical member 3 has a sharp shape that gradually decreases in thickness as it goes to the end portion, the air flowing through the first air passage 2a and the compressed air outlet The compressed air discharged from the first air passage 2a to the first air passage 2a smoothly merges, reducing the energy loss around the compressed air outlet 5b and further increasing the volumetric flow rate of the air in the first air passage 2a. it can.
 それに加えて、第2筒部材4の縮径面4d、同径面4e、及び拡径面4fによって、第1エア通路2aのエア吹出口2c側においてその他の部分よりも断面積の小さい部分が形成されるので、当該部分において通過するエアの流速が速くなって第1エア通路2aのエア吸込口2b側の負圧が高く維持されるようになる。したがって、エア吸込吹出ツール1のエア吸込力及びエア吹出力をさらに高めることができる。 In addition, due to the reduced diameter surface 4d, the same diameter surface 4e, and the enlarged diameter surface 4f of the second cylindrical member 4, a portion having a smaller cross-sectional area than the other portions on the air outlet 2c side of the first air passage 2a. Since it is formed, the flow velocity of the air passing through the portion is increased, and the negative pressure on the air suction port 2b side of the first air passage 2a is maintained high. Therefore, the air suction force and the air blowing output of the air suction blowing tool 1 can be further increased.
 本発明は、筒状をなすツール内部に圧縮エアを導入することにより、ツール内部に筒中心軸に沿う大容量のエア流れを発生させて吸込作業又は吹出作業を可能にするエア吸込吹出ツールに適している。 The present invention provides an air suction / blowout tool that allows suction work or blowout work by introducing a large amount of air flow along the center axis of the cylinder inside the tool by introducing compressed air into the cylindrical tool. Is suitable.
