然而，專利文獻1的噴霧噴嘴裝置中，必須各別對液體供給與氣體供給進行控制，對噴霧噴嘴裝置的使用者而言，有作業費事的問題。亦即，開始使用噴霧噴嘴裝置時，必須從液體供給路上游側開始供給液體，與此同時，從氣體供給路上游側開始供給氣體。再者，相反地，噴霧噴嘴裝置欲結束使用時，必須各別停止氣體與液體的供給。 However, in the spray nozzle device of Patent Document 1, it is necessary to control the liquid supply and the gas supply separately, and there is a problem that the user of the spray nozzle device has a troublesome work. That is, when starting to use the spray nozzle device, it is necessary to start supplying liquid from the upstream side of the liquid supply path, and at the same time, start supplying gas from the upstream side of the gas supply path. On the contrary, when the spray nozzle device is to be ended, the supply of gas and liquid must be stopped separately.
本發明係有鑒於上述情形而研創的發明，課題在於提供可藉由控制一方流體的供給、不供給來進行噴霧、不噴霧之控制的噴霧噴嘴裝置。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a spray nozzle device capable of controlling spraying and non-spraying by controlling the supply and non-supply of one fluid.

依此方式，藉由在液體噴出噴嘴與噴霧噴嘴之間形成壓縮氣體噴出路，壓縮氣體可從液體噴出噴嘴的周圍施行噴射，而和液體接觸。依此方式，藉由液體和壓縮氣體的接觸，即可使液體微粒化而行噴霧。 In this manner, by forming a compressed gas ejection path between the liquid ejection nozzle and the spray nozzle, the compressed gas can be ejected from the periphery of the liquid ejection nozzle and come into contact with the liquid. In this way, by contacting the liquid with the compressed gas, the liquid can be atomized and sprayed.

依此方式，藉由設置決定噴霧噴嘴之滑動位置的定位手段，液體噴出噴嘴之噴出口與閥體的隔開距離可加以調節，俾控制噴霧量。 In this way, by setting the positioning means that determines the sliding position of the spray nozzle, the separation distance between the discharge port of the liquid spray nozzle and the valve body can be adjusted to control the spray amount.
若依本發明，可提供一種藉由控制一方流體的供給、不供給即可進行噴霧、不噴霧之控制的噴霧噴嘴裝置。 According to the present invention, it is possible to provide a spray nozzle device capable of performing spray and non-spray control by controlling the supply and non-supply of a fluid.

However, the technical scope of the present invention is not limited to the embodiments shown in the drawings, and can be appropriately changed within the scope described in the patent application scope.
圖1為本發明噴霧噴嘴裝置的分解斜視圖，圖2為圖1的組裝狀態外觀斜視圖。再者，圖3為沿著圖2中F3-F3線的本發明噴霧噴嘴裝置的剖面圖。 FIG. 1 is an exploded perspective view of a spray nozzle device according to the present invention, and FIG. 2 is an external perspective view of an assembled state of FIG. 1. Moreover, FIG. 3 is a cross-sectional view of the spray nozzle device of the present invention, taken along line F3-F3 in FIG. 2.
如圖1至圖3所示，該噴霧噴嘴裝置具備：噴嘴本體10，具有連接於氣體供給路12的殼體11；液體噴出噴嘴20，設於該殼體11內；噴霧噴嘴30，設成可沿著該液體噴出噴嘴20滑動；殼體11的蓋構件40，具有露出該噴霧噴嘴30的貫通孔41；及彈簧50(勢能賦予手段之一例)，使噴霧噴嘴30向該基端側賦予勢能。 As shown in FIGS. 1 to 3, the spray nozzle device includes a nozzle body 10 having a housing 11 connected to a gas supply path 12, a liquid ejection nozzle 20 provided in the housing 11, and a spray nozzle 30 provided. It can slide along the liquid ejection nozzle 20; the cover member 40 of the housing 11 has a through hole 41 that exposes the spray nozzle 30; and a spring 50 (an example of a potential energy application means) for applying the spray nozzle 30 to the base end side Potential energy.
另外，本實施形態中，係以沿著X方向從噴嘴本體10朝向蓋構件40的方向為作上方向，相反的，從蓋構件40朝向噴嘴本體10的方向則作為下方向，藉以決定上下方向。再者，該X方向和噴霧噴嘴裝置的軸方向係屬同義。 In addition, in this embodiment, the direction from the nozzle body 10 to the cover member 40 along the X direction is taken as the upward direction. On the contrary, the direction from the cover member 40 to the nozzle body 10 is used as the downward direction to determine the vertical direction. . The X direction is synonymous with the axial direction of the spray nozzle device.
噴嘴本體10具有：殼體11，形成有底筒狀；氣體供給路12，將供應自壓縮氣體供給手段(未圖示)的壓縮氣體供給至殼體11內；及加壓室13，藉所供給的壓縮氣體施以加壓。該殼體11的內周壁形成有供蓋構件40連接的連接母螺紋部14，殼體11與蓋構件40之間則收容有噴霧噴嘴30及彈簧50。 The nozzle body 10 includes a casing 11 formed in a bottomed cylindrical shape, a gas supply path 12 for supplying compressed gas supplied from a compressed gas supply means (not shown) into the casing 11, and a pressurizing chamber 13 for borrowing. The supplied compressed gas is pressurized. A connection female screw portion 14 for connecting the cover member 40 is formed on an inner peripheral wall of the casing 11, and a spray nozzle 30 and a spring 50 are housed between the casing 11 and the cover member 40.
液體噴出噴嘴20係形成為筒狀，其具有和X方向平行之外周面20a，且其係突設於殼體11的底部中央位置。該液體噴出噴嘴20具有：液體噴出口21，用於噴出液體；及液體供給路22，將供應自液體供給手段(未圖示)的液體向液體噴出口21輸送。 The liquid ejection nozzle 20 is formed in a cylindrical shape, has an outer peripheral surface 20 a parallel to the X direction, and is protruded from a central position of the bottom of the casing 11. The liquid ejection nozzle 20 includes a liquid ejection port 21 for ejecting liquid, and a liquid supply path 22 that conveys liquid supplied from a liquid supply means (not shown) to the liquid ejection port 21.
噴霧噴嘴30具有：上側(前端側)的筒狀部31；下側(基端側)的突緣部32；封閉筒狀部31之前端的端板33；設於該端板33的複數個噴霧口34；設於突緣部32下面的受壓面35；及藉噴霧噴嘴30之滑動位置來開閉液體噴出噴嘴20之液體噴出口21的閥體36。 The spray nozzle 30 includes a cylindrical portion 31 on the upper side (front end side), a flange portion 32 on the lower side (base end side), an end plate 33 that closes the front end of the cylindrical portion 31, and a plurality of sprays provided on the end plate 33. A port 34; a pressure receiving surface 35 provided below the flange portion 32; and a valve body 36 that opens and closes the liquid discharge port 21 of the liquid discharge nozzle 20 by the sliding position of the spray nozzle 30.
如圖3所示，閥體36係形成大致圓錐狀，形成有從下向上擴開地傾斜的錐面36a(合流手段)。該錐面36a係藉由向液體噴出口21之閥座21a賦予勢能而呈液密抵接。再者，該閥體36頂部的角度係設定為20度左右。該錐面36a則對於X方向具有10度左右的傾斜。 As shown in FIG. 3, the valve body 36 is formed in a substantially conical shape, and is formed with a tapered surface 36a (combining means) that is inclined to widen from the bottom to the top. The tapered surface 36 a comes into liquid-tight contact by applying potential energy to the valve seat 21 a of the liquid discharge port 21. The angle of the top of the valve body 36 is set to about 20 degrees. The tapered surface 36a has an inclination of about 10 degrees in the X direction.
筒狀部31之外徑係形成小於突緣部32的外徑，筒狀部31的外周面31a位於較突緣部32的外周面32a偏靠內側的位置。因此，在外周面31a與外周面32a的交界位置形成有和Y方向平行的環狀平面37。此外，外周面31a及外周面32a係為平行於X方向的面。 The outer diameter of the cylindrical portion 31 is smaller than the outer diameter of the flange portion 32. The outer peripheral surface 31 a of the cylindrical portion 31 is located closer to the inside than the outer peripheral surface 32 a of the flange portion 32. Therefore, an annular plane 37 parallel to the Y direction is formed at the boundary position between the outer peripheral surface 31a and the outer peripheral surface 32a. The outer peripheral surface 31a and the outer peripheral surface 32a are surfaces parallel to the X direction.
再者，筒狀部31與突緣部32的內徑大小係相同，噴霧噴嘴30形成有和X方向平行的內周面30a。該噴霧噴嘴30的內徑係形成為大於液體噴出噴嘴20的外徑。藉此構成，噴霧噴嘴30的內周面30a與液體噴出噴嘴20的外周面20a之間即形成有作為壓縮氣體的噴出路GP的間隙D。 The inner diameter of the cylindrical portion 31 and the flange portion 32 are the same, and the spray nozzle 30 is formed with an inner peripheral surface 30a parallel to the X direction. The inner diameter of the spray nozzle 30 is larger than the outer diameter of the liquid ejection nozzle 20. With this configuration, a gap D is formed between the inner peripheral surface 30 a of the spray nozzle 30 and the outer peripheral surface 20 a of the liquid ejection nozzle 20 as a compressed gas ejection path GP.
蓋構件40具有：供噴霧噴嘴30的筒狀部31插通的貫通孔41；氣密螺合於殼體11之連接母螺紋部14的連接公螺紋部42；及顯示該連接公螺紋部42之進入位置的導引線43。 The cover member 40 includes a through-hole 41 through which the cylindrical portion 31 of the spray nozzle 30 is inserted, a connection male screw portion 42 that is air-tightly screwed to the connection female screw portion 14 of the housing 11, and shows the connection male screw portion 42. Of the entry position 43.
貫通孔41的內周形成有：可抵接於筒狀部31之外周面31a的第1滑動面41a；及可抵接於突緣部32之外周面32a的第2滑動面41b。亦即，藉由這些滑動面產生引導噴霧噴嘴30沿液體噴出噴嘴20滑動的作用，即可在形成有間隙D的狀態下朝上下方向滑動。 The inner periphery of the through-hole 41 is formed with a first sliding surface 41 a that can abut against the outer peripheral surface 31 a of the cylindrical portion 31, and a second sliding surface 41 b that can abut against the outer peripheral surface 32 a of the flange portion 32. That is, the sliding surface guides the spray nozzle 30 to slide along the liquid ejection nozzle 20, so that it can slide in the vertical direction while the gap D is formed.
此外，噴霧噴嘴30與蓋構件40之間形成有收容彈簧50的空間S。該空間S係形成在口徑小於第1滑動面41a的內周面41c與筒狀部31的外周面31a之間。 A space S is formed between the spray nozzle 30 and the cover member 40 to accommodate the spring 50. The space S is formed between the inner peripheral surface 41 c having a smaller diameter than the first sliding surface 41 a and the outer peripheral surface 31 a of the cylindrical portion 31.
而且，在第1滑動面41a與內周面41c的交界位置形成有供彈簧50之一端抵接的抵接面44。此外，在內周面41c及第2滑動面41b的交界形成有決定噴霧噴嘴30之滑動極限位置的停止面45(定位手段之一例)。 Further, a contact surface 44 is formed at the boundary position between the first sliding surface 41 a and the inner peripheral surface 41 c for one end of the spring 50 to abut. Further, a stop surface 45 (an example of a positioning means) that determines the sliding limit position of the spray nozzle 30 is formed at the boundary between the inner peripheral surface 41c and the second sliding surface 41b.
該停止面45與環狀平面37之間形成有可供噴霧噴嘴30滑動的活動區域H。該活動區域H可藉由調節連接公螺紋部42與連接母螺紋部14的相對位置而作適當改變。然後，藉由確認顯示連接公螺紋部42進入位置的導引線43即得以掌握活動區域H的長度。圖3中，係顯示形成有上側導引線43a及下側導引線43b的2條線的情況。 Between the stop surface 45 and the annular flat surface 37, a movable area H is formed in which the spray nozzle 30 can slide. The movable area H can be appropriately changed by adjusting the relative positions of the connection male screw portion 42 and the connection female screw portion 14. Then, the length of the active area H can be grasped by confirming that the guide wire 43 connecting the male screw portion 42 is entered. FIG. 3 shows a case where two lines of the upper guide line 43a and the lower guide line 43b are formed.
彈簧50係設於筒狀部31之外周面31a的周圍，其一端側抵接於蓋構件40的抵接面44，另一端側抵接於噴霧噴嘴30的環狀平面37。藉由該彈簧50，噴霧噴嘴30會被向下側(噴霧噴嘴30的基端側)賦予勢能。因此，設於噴霧噴嘴30的閥體36會被朝液體噴出口21的閥座21a賦予勢能而形成液密抵接。 The spring 50 is provided around the outer peripheral surface 31 a of the cylindrical portion 31, and one end side thereof is in contact with the contact surface 44 of the cover member 40, and the other end side thereof is in contact with the annular flat surface 37 of the spray nozzle 30. With this spring 50, the spray nozzle 30 is given potential energy to the lower side (the base end side of the spray nozzle 30). Therefore, the valve body 36 provided in the spray nozzle 30 is liquid-tightly contacted by the potential energy given to the valve seat 21 a of the liquid discharge port 21.
接著，參照圖3及圖4詳細說明有關本發明噴霧噴嘴裝置的開閉動作。圖3為顯示噴霧噴嘴裝置的閉狀態(閥體36被向閥座21a賦予勢能的狀態)的側剖面圖。在此閉狀態中，藉由彈簧50的彈力，閥體36會被向閥座21a賦予勢能，而呈液密抵接狀態，使液體不會噴出。 Next, the opening and closing operation of the spray nozzle device according to the present invention will be described in detail with reference to FIGS. 3 and 4. FIG. 3 is a side sectional view showing a closed state (a state where the valve body 36 is given potential energy to the valve seat 21a) of the spray nozzle device. In this closed state, the valve body 36 is given potential energy to the valve seat 21a by the elastic force of the spring 50, and is in a liquid-tight contact state, so that the liquid will not be ejected.
圖4係顯示噴霧噴嘴裝置之開狀態(閥體36離開閥座21a的狀態)的側剖面圖。在此開狀態中，首先，從氣體供給路12對殼體11的加壓室13導入壓縮氣體。接著，藉由導入的壓縮氣體使加壓室13內的壓力增高，且藉由該壓力作用於受壓面35，使噴霧噴嘴30往上方向滑動。此處，噴霧噴嘴30只滑動活動區域H的長度，然後，環狀平面37就會和停止面45接觸並施行定位。藉由閥體36隨著該噴霧噴嘴30的滑動而上升，錐面36a會從閥座21a離開寬度W之量。該寬度W的大小係對應活動區域H的長度，藉由短縮設定活動區域H，即可窄縮寬度W以調節液體的噴出量。 FIG. 4 is a side sectional view showing an opened state of the spray nozzle device (a state where the valve body 36 is separated from the valve seat 21a). In this open state, first, compressed gas is introduced into the pressurizing chamber 13 of the casing 11 from the gas supply path 12. Next, the pressure in the pressurizing chamber 13 is increased by the introduced compressed gas, and the pressure is applied to the pressure receiving surface 35 to slide the spray nozzle 30 upward. Here, the spray nozzle 30 slides only the length of the active area H, and then, the annular flat surface 37 contacts the stop surface 45 and performs positioning. When the valve body 36 rises in accordance with the sliding of the spray nozzle 30, the tapered surface 36a is separated from the valve seat 21a by the width W. The width W corresponds to the length of the active area H. By setting the active area H short, the width W can be narrowed to adjust the amount of liquid ejected.
圖5係顯示藉由將蓋構件40進入殼體11至上側導引線43a的位置使寬度W縮小，而將液體的噴出量設定為最小值的狀態。 FIG. 5 shows a state in which the width W is reduced by setting the cover member 40 into the housing 11 to the upper guide line 43a to set the ejection amount of the liquid to the minimum value.
作為該開狀態的條件，可設定成例如以0.035MPa的壓縮空氣壓力使噴霧噴嘴30滑動，停止時彈簧最低設定力為0.1257kg，設計上的彈簧設定壓力則設定在0.4kg。再者，標準空氣壓力可例示為0.4MPa，最低空氣壓力為0.2MPa，最大液體壓力為0.4MPa。 As the condition of the open state, for example, the spray nozzle 30 can be slid with compressed air pressure of 0.035 MPa, and the minimum spring setting force is 0.1257 kg when stopped, and the design spring setting pressure is set to 0.4 kg. Furthermore, the standard air pressure can be exemplified as 0.4 MPa, the minimum air pressure is 0.2 MPa, and the maximum liquid pressure is 0.4 MPa.
接著，參照圖6詳細說明有關本發明噴霧噴嘴裝置進行噴霧的狀況。壓縮空氣係從形成在噴霧噴嘴30之內周面30a與液體噴出噴嘴20之外周面20a間的間隙D(參照圖3至圖5)朝和X方向平行的方向噴出(壓縮氣體的噴出路GP)。另一方面，液體則從形成在錐面36a與閥座21a間的寬度W(參照圖4或圖5)，藉由改變噴出液體的朝向使其和噴出氣體形成合流而作為合流手段的錐面36a，向和壓縮氣體的噴出路GP交叉的方向噴出(液體噴出路LP)。 Next, the state of spraying by the spray nozzle device of this invention is demonstrated in detail with reference to FIG. Compressed air is ejected from a gap D (see FIGS. 3 to 5) formed between the inner peripheral surface 30 a of the spray nozzle 30 and the outer peripheral surface 20 a of the liquid ejection nozzle 20 (the compressed gas ejection path GP ). On the other hand, from the width W (see FIG. 4 or FIG. 5) formed between the tapered surface 36a and the valve seat 21a, the liquid is changed into a tapered surface that merges with the discharged gas by changing the direction of the discharged liquid. 36a, eject in a direction intersecting the ejection path GP of the compressed gas (liquid ejection path LP).
依此方式，藉由設定液體噴出方向和氣體噴出方向交叉的方向，使噴出液體碰撞噴出氣體，即可產生粒徑細小的微細化液滴。 In this way, by setting the direction in which the liquid ejection direction and the gas ejection direction intersect, the ejection liquid collides with the ejection gas, so that micronized droplets having a small particle diameter can be generated.
若依本發明，藉由具備閥體36，以壓縮氣體的壓力來開閉液體噴出噴嘴20之液體噴出口21，即可輕易控制該噴霧噴嘴裝置的噴霧、不噴霧。亦即，在噴霧噴嘴裝置進行噴霧時，藉由供給壓縮氣體，噴霧噴嘴30會向上方滑動，使液體噴出口21打開而施行噴霧。相對的，在噴霧噴嘴裝置不欲噴霧時，只要停止供給壓縮氣體，閥體36就會液密抵接於閥座21a，液體的噴出也停止。依此方式，該噴霧噴嘴裝置的使用者只要控制壓縮氣體的供給、不供給，不需要其他多餘的動作。 According to the present invention, by providing the valve body 36 to open and close the liquid ejection port 21 of the liquid ejection nozzle 20 with the pressure of the compressed gas, the spraying and non-spraying of the spraying nozzle device can be easily controlled. That is, when spraying is performed by the spray nozzle device, the spray nozzle 30 slides upward by supplying compressed gas, and the liquid ejection port 21 is opened to perform spraying. In contrast, when the spray nozzle device does not intend to spray, as long as the supply of the compressed gas is stopped, the valve body 36 abuts on the valve seat 21a in a liquid-tight manner, and the discharge of the liquid is stopped. In this way, as long as the user of the spray nozzle device controls the supply and non-supply of the compressed gas, other unnecessary actions are not required.
再者，若依本發明，藉由調節蓋構件40與殼體11的相對位置，即可調節該噴霧噴嘴裝置的噴霧量。亦即，作為液體噴出口的寬度W的大小雖係藉由噴霧噴嘴30滑動的活動區域H的長度來決定，但該活動區域H的長度卻是藉蓋構件40之停止面45位置來設定。因此，藉由調節蓋構件40與殼體11的相對位置，即可容易調節噴霧量。 Furthermore, according to the present invention, the spraying amount of the spray nozzle device can be adjusted by adjusting the relative position of the cover member 40 and the casing 11. In other words, although the width W of the liquid ejection port is determined by the length of the movable region H where the spray nozzle 30 slides, the length of the movable region H is set by the position of the stop surface 45 of the cover member 40. Therefore, by adjusting the relative position of the cover member 40 and the casing 11, the spray amount can be easily adjusted.
