Description

  The present invention relates to a spraying device for spraying liquid such as lotion.

  Conventionally, as a spraying device that sprays liquid such as skin lotion for beauty and health purposes, for example, a fluid ejection unit that ejects fluid from an ejection nozzle and a liquid ejection unit that ejects liquid from an ejection nozzle can be separated A separate system is known (see Patent Document 1). A container that stores a liquid is attached to the liquid discharge unit. When the spraying device is used, the fluid ejecting unit and the liquid ejecting unit are connected, so that the ejecting nozzle and the ejecting nozzle are arranged so that the directions in which the nozzles extend are orthogonal to each other. When the fluid is ejected from the ejection nozzle, the vicinity of the tip of the ejection nozzle is decompressed, so that the liquid is sucked up through the flow path of the liquid ejection section and the liquid is ejected from the ejection nozzle. The discharged liquid is atomized by jetting the fluid. In such a separate spraying device, for example, the operation of detaching the container from the liquid ejection unit can be performed smoothly by separating the fluid ejection unit and the liquid ejection unit. Further, for example, since only the liquid ejection part can be cleaned, maintenance of the liquid ejection part is facilitated.

JP 2003-88781 A

  In the above-described separable spray device, the atomization of the liquid becomes unstable, and as a result, the liquid may not be atomized. The present invention was made by finding out that the atomization of the liquid is unstable due to the relative position of the ejection nozzle and the ejection nozzle being shifted in a state where the fluid ejection section and the liquid ejection section are connected. Is.

  An object of the present invention is to provide a spraying device that can easily realize stable atomization even when the fluid ejecting unit and the liquid discharging unit are separable.

  In order to achieve the above object, the invention according to claim 1 includes a fluid ejecting unit that ejects fluid from the ejection nozzle and a liquid ejection unit that ejects liquid from the ejection nozzle, and the fluid ejecting unit and the liquid A spraying device having a connecting structure for detachably connecting to a discharge unit, wherein the liquid is discharged and atomized by jetting the fluid, and is in contact with the jet nozzle or the discharge nozzle along with the connection The gist is that a positioning member for positioning a relative position between the ejection nozzle and the discharge nozzle is provided.

  In the conventional spraying device, for example, when connecting and separating the fluid ejecting unit and the liquid ejecting unit, or attaching / detaching a container for storing liquid to / from the liquid ejecting unit, an unnecessary force is applied to the nozzle to cause fluid flow. There is a possibility that the position of the tip of the nozzle in the ejection unit or the liquid ejection unit is shifted. The spray device having the above-described configuration includes a positioning member that contacts the ejection nozzle or the ejection nozzle and positions the relative position with the nozzle as the fluid ejection unit and the liquid ejection unit are connected.

The gist is that

  In the connection structure connected by the slide, the connection operation can be smoothly performed by providing a certain margin for the dimension in the direction orthogonal to the direction of the slide. However, such a dimension setting may cause a change in the relative position between the fluid ejecting unit and the liquid ejecting unit, which may easily cause misalignment between the ejecting nozzle and the ejecting nozzle. In this regard, the positioning member is supported by the fluid ejecting unit such that the gap between the first projecting piece and the second projecting piece extends along the sliding direction. Thereby, since the discharge nozzle inserted in the gap between the first protrusion and the second protrusion is sandwiched from the direction orthogonal to the direction of the slide, the positional deviation based on the connection by the slide is suitably corrected. It becomes like this. Thereby, it becomes easy to make smooth connection operation and stable atomization compatible.

The gist of the mounting portion and the injection portion main body includes a restriction portion that restricts the attachment portion from rotating in the circumferential direction with respect to the central axis of the injection nozzle.

  According to this configuration, since the attachment portion is sandwiched between the injection nozzle and the injection portion main body, the positioning member is not easily inclined with respect to the direction in which the injection nozzle extends. In addition, the rotation of the attachment portion is restricted by the restriction portion. Therefore, the position of the positioning member with respect to the injection nozzle is easily maintained to be a predetermined position. As a result, for example, even when separation and connection are repeated, the accuracy of positioning of the relative position is easily maintained. .

The base end side of the casing 13 is configured as a gripping part that grips when the spray device is used. The metal injection nozzle 11 projecting from the tip of the casing 13 has a flow path extending along the X-axis direction and has a conical shape as a whole. The injection nozzle 11 is connected to the flow path member 14 so that the flow path of the injection nozzle 11 communicates with the flow path of the flow path member 14. On the lower surface of the casing 13, an inflow portion 16 through which a fluid flows into the flow path member 14 is projected.

  A fluid supply source is connected to the inflow portion 16 via a hose (not shown). For example, a liquefied gas cylinder or an air compressor is used as the fluid supply source. The fluid flowing in from the inflow portion 16 is ejected from the tip of the ejection nozzle 11 through the flow path member 14. The flow path member 14 of the present embodiment is provided with an on-off valve and a throttle valve (not shown). The on-off valve is opened by pressing the operation button 17 protruding from the upper surface of the casing 13. The throttle valve adjusts the flow rate of the fluid through the flow path of the flow path member 14 by operating the flow rate adjustment dial 18 exposed from the intermediate portion of the casing 13. The flow path member 14 having such an on-off valve and a throttle valve can employ a configuration similar to that of Patent Document 1.

Next, the positioning member supported by the fluid ejecting unit 12 will be described.
A positioning member 51 is supported at the tip of the casing 13. The positioning member 51 comes into contact with the discharge nozzle 31 in connection with the connection between the fluid ejecting unit 12 and the liquid ejection unit 32 and positions the relative position between the ejection nozzle 11 and the ejection nozzle 31. The positioning member 51 is supported by the fluid ejecting unit 12 so as to be in a predetermined position with reference to the opening at the tip of the ejecting nozzle 11.

  As shown in FIG. 2A, in the positioning member 51, an annular attachment portion 52 and a bifurcated positioning portion 53 are integrally formed via an L-shaped support portion. A pair of locking claws 52 a protrude from the inner peripheral surface of the mounting portion 52. The pair of locking claws 52a are arranged to face each other along the Z-axis direction. On the other hand, a ridge 19 having an annular shape along the circumferential direction of the opening is formed at the front end opening portion of the casing 13, and a pair of notch portions 20 facing each other along the Z-axis direction is formed on the ridge 19. ing. Each notch 20 is formed using the dividing surface of the casing 13, that is, the boundary between the casings 13a and 13b.

  As shown in FIG. 2B, the mounting portion 52 is externally fitted to the ridge 19 and the locking claw 52 a is locked to the cutout portion 20, so that the circumferential direction of the central axis of the injection nozzle 11 The rotation of the attachment portion 52 with respect to (the circumferential direction of the X axis) is restricted. The attachment portion 52 is sandwiched between the injection nozzle 11 and the casing 13 by screwing the proximal end portion of the injection nozzle 11 to the flow path member 14.

  As shown in FIGS. 2A and 2B, the positioning portion 53 includes a first projecting piece 55 and a second projecting piece 56 that extend along the X-axis direction, respectively. Each of the projecting pieces 55 and 56 is arranged to be separated from the outer diameter of the discharge nozzle 31 in the Y-axis direction, so that the discharge nozzle 31 is inserted from a gap at the tip of each of the projecting pieces 55 and 56. The discharge nozzle 31 is sandwiched between the opposed surfaces 55a and 56a of the projecting pieces 55 and 56, respectively. Further, the tip portions of the projecting pieces 55 and 56 are formed in an arc shape so that the opposing surfaces 55a and 56a at the tip portions of the projecting pieces 55 and 56 are directed toward the tips of the projecting pieces 55 and 56. It is separated. As shown in FIG. 3, the positioning portion 53 is disposed below the tip of the injection nozzle 11 by the support portion 54, and the tip of the positioning portion 53 protrudes from the tip of the injection nozzle 11.

  The material of the positioning member 51 can be selected as appropriate according to the desired mechanical properties and the like, but is preferably formed of a metal material from the viewpoint that it is easy to improve dimensional accuracy and rigidity, for example.

Next, the liquid discharge unit 32 will be described.
As shown in FIG. 1 and FIG. 3, the liquid discharge part 32 includes a resin discharge part main body 33 and a discharge nozzle 31 provided on the upper part. The discharge portion main body 33 has a cap shape and is configured to be screwed into the opening portion of the container 71 that stores the liquid. The discharge nozzle 31 is provided so as to extend along the Z-axis direction, so that the flow path of the discharge nozzle 31 and the flow path of the injection nozzle 11 are arranged so as to be substantially orthogonal. The discharge nozzle 31 of the present embodiment is screwed to the discharge unit main body 33 and can be rotated around the Z axis by a rotation operation unit 34 provided on the discharge nozzle 31. . By rotating the discharge nozzle 31 clockwise or counterclockwise by the rotation operation unit 34, the position (vertical position) along the central axis direction (Z-axis direction) of the tip of the discharge nozzle 31 is adjusted. A compression coil spring is interposed between the rotation operation unit 34 and the discharge unit main body 33, and unnecessary rotation of the discharge nozzle 31 is suppressed. Such a position adjustment mechanism that adjusts the position of the discharge nozzle 31 along the central axis direction is a well-known mechanism, and a configuration similar to that described in Patent Document 1 can be adopted. Since the discharge nozzle 31 provided with such a position adjusting mechanism can be easily detached from the discharge portion main body 33, maintenance such as replacement of the discharge nozzle 31 can be easily performed.

  The base end of the tube 72 is connected to the lower end of the discharge nozzle 31. The distal end side of the tube 72 is disposed in the container 71. The lotion is stored in the container 71, and the distal end side of the tube 72 is put into the lotion. In addition, the discharge part main body 33 of this embodiment is screwed with the opening part of the container 71 liquid-tightly. In addition, a through hole (not shown) is formed in the upper part of the discharge unit main body 33, and the pressure in the container 71 is substantially constant. The skin lotion exhibits functions such as moisturizing, epithelial cell proliferation, and antioxidant based on the cosmetic ingredients. The component contained in the skin lotion may be a natural component or a synthetic component. Specific examples of the components contained in the skin lotion include proteins such as collagen and EGF (epidermal growth factor), mucopolysaccharides such as hyaluronic acid, fullerenes and amino acids.

Next, a connection structure between the injection unit main body 15 and the discharge unit main body 33 will be described.
As shown in FIG. 1, a first connecting portion 21 having an inverted T shape is suspended from the front end side of the casing 13. The first connecting portion 21 includes a slide portion 22 having an XY plane and a bracket 23 that is provided on the lower surface on the front end side of the casing 13 and supports the slide portion 22. The first connecting portion 21 is formed integrally with the casings 13a and 13b and is formed by assembling the casings 13a and 13b.

  On the other hand, the discharge portion main body 33 is provided with a second connecting portion 35 to be inserted by sliding along the X-axis direction of the slide portion 22. The second connecting portion 35 includes an upper surface 36 of the discharge portion main body 33 and a pair of guide pieces 37 extending along the X-axis direction. When the slide portion 22 is inserted between the guide pieces 37, the slide portion 22 is provided. Movement in the Z-axis direction (vertical direction) is restricted. More specifically, each guide piece 37 has an inverted L shape, and both side portions of the slide portion 22 are sandwiched between each guide piece 37 and the upper surface 36 of the discharge portion main body 33. Then, the slide part 22 is slid until its tip comes into contact with a standing wall 38 that forms the inner part of the second connection part 35, whereby the injection part body 15 and the discharge part body 33 are connected.

  The slide portion 22 and the discharge portion main body 33 are locked together with the connection between the ejection portion main body 15 and the discharge portion main body 33, and the separation operation for extracting the slide portion 22 from the second connection portion 35 is performed as described above. You may provide the latching | locking part from which latching is cancelled | released. For example, the irregularities formed on the upper surface 36 of the discharge portion main body 33 and the lower surface of the slide portion 22 can be locked as locking portions. By providing such a locking portion, it is possible to suppress the slide portion 22 from coming out of the second connecting portion 35.

Next, the operation of the spray device of this embodiment will be described.
In order to use the spray device, a fluid supply source is connected to the inflow portion 16, and the container 71 storing the lotion is attached to the discharge portion main body 33. In the present embodiment, a liquefied carbon dioxide cylinder suitable for the spraying of the skin lotion is used as the liquid supply source. Next, the slide part 22 is inserted between the guide pieces 37 in order to connect the fluid ejecting part 12 and the liquid discharge part 32.

  Here, in FIGS. 4 and 5, the position of the discharge nozzle 31 before being inserted into the gap between the protrusions 55 and 56 is indicated by a two-dot chain line. 4 and 5, the degree of positional deviation of the discharge nozzle 31 is exaggerated for easy understanding. In this state, the opening center of the discharge nozzle 31 is shifted toward the first projecting piece 55 with respect to the opening center of the ejection nozzle 11. Subsequently, as the slide portion 22 is slid between the guide pieces 37, the discharge nozzle 31 comes into contact with the first protrusion 55 and is pressed toward the second protrusion 56. The discharge nozzle 31 is inserted into the gap between the first projecting piece 55 and the second projecting piece 56. In a state where the slide portion 22 is slid until it comes into contact with the standing wall 38, the discharge nozzle 31 is sandwiched by the projecting pieces 55 and 56 from a direction orthogonal to the slide direction (direction along the X axis). Thus, the center of the opening of the discharge nozzle 31 is arranged at a predetermined position that is substantially the center of the opening of the ejection nozzle 11 in a direction (direction along the Y axis) orthogonal to the direction of the slide.

  In the connecting operation described above, the discharge nozzle 31 is inserted into the gap between each of the projecting pieces 55 and 56 while being pressed and guided by the opposing surface 55a of the front end portion of the first projecting piece. For this reason, the discharge nozzle 31 is less likely to be caught on the tip of the first projecting piece 55, so that a smooth coupling operation is realized.

  4 and 5, the case where the discharge nozzle 31 is displaced toward the first projecting piece 55 has been described. However, the same effect can be obtained when the ejection nozzle 31 is displaced toward the second projecting piece 56. Will be omitted.

  In order to atomize the lotion with the spraying device, the fluid is ejected from the ejection nozzle 11 by holding the proximal end side of the casing 13 and pressing the operation button 17. By sucking carbon dioxide gas, the vicinity of the tip of the discharge nozzle 31 is depressurized, so that a suction force for sucking the lotion in the container 71 acts. By the suction force, the lotion is sucked up through the tube 72, whereby the lotion is discharged from the discharge nozzle 31. The discharged skin lotion is atomized by the injection of carbon dioxide and discharged in the direction in which the carbon dioxide is jetted. At this time, the center of the opening of the discharge nozzle 31 is disposed at a predetermined position that is substantially the center of the opening of the ejection nozzle 11 in the direction along the Y axis. For this reason, with the injection of carbon dioxide gas, a sufficient suction force for sucking in the skin lotion is obtained, and the carbon dioxide gas is sufficiently mixed with the discharged skin lotion, so that the skin water can be stably atomized. Realized. The skin lotion that has been atomized and released is sprayed onto the face and the like, so that the cosmetic ingredients contained in the skin lotion act on the skin and the like.

  When the lotion in the container 71 is used up or another lotion is used, the container 71 is removed from the discharge unit main body 33 after the fluid ejecting unit 12 and the liquid discharge unit 32 are separated. Subsequently, the container 71 replenished with lotion and the container 71 storing lotions of different types are attached to the discharge unit main body 33. Then, the relative position of the injection nozzle 11 and the discharge nozzle 31 is positioned by the positioning member 51 by connecting the injection unit main body 15 and the discharge unit main body 33. That is, even if the separation and connection of the fluid ejecting unit 12 and the liquid ejecting unit 32 are repeated, the position of the ejecting nozzle 31 with respect to the ejecting nozzle 11 is adjusted to a predetermined position set in advance.

The effects exhibited by this embodiment will be described below.
(1) For example, when the liquid ejection unit 32 is separated from the fluid ejection unit 12 and the container 71 is attached to and detached from the liquid ejection unit 32, an unnecessary force is applied to the ejection nozzle 31 to eject to the ejection unit main body 33. There is a possibility that the position of the tip of the nozzle 31 is shifted. In this regard, in the spray device, since the positioning member 51 is provided, the position of the discharge nozzle 31 with respect to the ejection nozzle 11 can be adjusted to a predetermined position set in advance by the positioning member 51. Therefore, even if the fluid ejecting unit 12 and the liquid discharging unit 32 are separable, it becomes easy to realize stable atomization.

  (2) Since the positioning member 51 is configured to position the discharge nozzle 31 by sandwiching the discharge nozzle 31 between the first protrusion 55 and the second protrusion 56, the position of the discharge nozzle 31 is any of the protrusions 55 and 56. Even in a state shifted in this direction, the discharge nozzle 31 can be adjusted to a predetermined position set in advance. Therefore, it becomes easier to realize stable atomization.

  (3) In the connection structure connected by the slide as described above, the connection operation can be smoothly performed by providing a certain margin for the dimension in the direction orthogonal to the direction of the slide. However, the setting of such dimensions may cause a change in the relative position between the ejection unit main body 15 and the ejection unit main body 33, and thus the positional deviation between the ejection nozzle 11 and the ejection nozzle 31 may easily occur. In this regard, the positioning member 51 of the present embodiment is supported by the fluid ejecting unit 12 such that the gap between the first projecting piece 55 and the second projecting piece 56 extends along the sliding direction. Thereby, since the discharge nozzle 31 is clamped by the protrusions 55 and 56 from the direction orthogonal to the direction of the slide, the positional deviation based on the connection by the slide is suitably corrected. Therefore, it becomes easy to achieve both smooth connection operation and stable atomization.

  (4) The facing surfaces 55 a and 56 a are separated from each other toward the tip at the tip of the first protrusion 55 and the tip of the second protrusion 56. According to this configuration, when the discharge nozzle 31 is inserted into the gap between the protrusions 55 and 56, the discharge nozzle 31 is guided by the distal end portion of the first protrusion piece 55 or the distal end portion of the second protrusion piece 56. The Thereby, since the discharge nozzle 31 is easily inserted between the projecting pieces 55 and 56, the connecting operation can be performed smoothly. In particular, it is effective in realizing a smooth coupling operation when the displacement of the discharge nozzle 31 is relatively large with respect to the relative position preset by the positioning member 51.

  (5) Since the attachment portion 52 is sandwiched between the injection nozzle 11 and the injection portion main body 15, the positioning member 51 is not easily inclined with respect to the direction in which the injection nozzle 11 extends. In addition, when the locking claw 52a is engaged with the cutout portion 20, the rotation of the attachment portion 52 is restricted. Accordingly, the position of the positioning member 51 with respect to the injection nozzle 11 is easily maintained to be a predetermined position. As a result, for example, even when separation and connection are repeated, the positioning accuracy of the relative position is maintained. It becomes easy.

  (6) By forming the notch portion 20 using the boundary between the casings 13a and 13b, a configuration in which the locking claw 52a is locked, that is, a regulating portion that regulates the rotation of the mounting portion 52 can be easily performed Can be provided.

(Example of change)
The above embodiment may be modified as follows.
-Although the said attaching part 52 is formed in cyclic | annular form, you may change into U shape etc., for example, and may be made to clamp between the injection nozzle 11 and the casing 13. FIG. Further, the mounting portion 52 is sandwiched between the spray nozzle 11 and the casing 13, but may be sandwiched between the spray nozzle 11 and the flow path member 14. In this case, by providing the notch portion 20 in the flow path member 14, it can be configured as a restricting portion that restricts the rotation of the attachment portion 52.

  -Although the said latching claw 52a is provided in a pair, rotation of the attaching part 52 can also be controlled by abbreviate | omitting any one latching claw 52a. The locking claw 52a and the notch 20 are disposed at a position along the Z-axis direction, but may be disposed at a position along the Y-axis direction, for example.

  The restricting portion that restricts the rotation of the attachment portion 52 is not limited to the locking claw 52a and the notch portion 20, and for example, a protrusion is provided on the ridge 19 and a recess or hole in which the protrusion is locked is provided as an attachment portion You may change into the structure formed in 52. FIG. Further, the casing 13 may be provided with a projection, and the mounting portion 52 may be modified with a recess or a hole in which the projection is locked. Thus, the said protrusion 19 can also be abbreviate | omitted by changing a control part.

  The positioning member 51 is attached to the fluid ejecting unit 12 by the mounting portion 52, but the mounting portion 52 may be omitted and the positioning member 51 may be provided by molding integrally with the spray nozzle 11 or the casing 13. it can. However, from the viewpoint of selecting a suitable material for the positioning member 51 and facilitating the molding of the positioning member 51, a configuration in which the positioning member 51 is formed separately from the fluid ejecting unit 12 is preferable.

  For example, when the displacement of the discharge nozzle 31 is less likely to occur than the ejection nozzle 11, the relative position between the ejection nozzle and the ejection nozzle is positioned with reference to the position of the ejection nozzle by providing a positioning member in the liquid ejection section. It can also be configured as follows.

  As the connection structure connected by the slide, a connection structure in which the guide piece 37 is provided in the fluid ejecting unit 12 and the slide part 22 is provided in the liquid discharge unit 32 may be employed. Further, the sliding direction of the embodiment is a direction along the direction in which the ejection nozzle 11 extends (X-axis direction), but the sliding direction is along the direction in which the discharge nozzle 31 extends (Z-axis direction). A guide piece 37 or the like can be provided as much as possible.

  -In the said embodiment, although the connection structure connected by a slide is employ | adopted, it is not limited to this, For example, it can also change into the connection structure not accompanied by a slide, such as connection by an uneven | corrugated fitting. That is, in any connection structure, for example, when the fluid ejecting unit 12 and the liquid ejecting unit 32 are separated and handled, an unnecessary force may be applied to the nozzle to cause a positional deviation of the nozzle. Therefore, it is effective to provide a positioning member.

-You may comprise each protrusion 55,56 so that the opposing surfaces 55a and 56a may become equal intervals over the whole protrusion 55,56.
6A and 6B, for example, when the discharge nozzle 31 is likely to be displaced in one direction with respect to the injection nozzle 11, the first projecting piece 55 and By omitting one of the second projecting pieces 56, the structure of the positioning member 51 can be simplified.

  -Although the said casing 13 has comprised the shape divided into two by making XZ plane into a division surface, for example, a division surface is good also as a YZ plane, and it is good also as a shape divided | segmented into three or more divisions. Further, the casing 13 may be omitted, and the fluid ejecting unit may be configured with the flow path member 14 itself as the ejecting unit main body. In this case, a grip portion may be coupled to the flow path member 14 in order to facilitate gripping of the fluid ejecting portion.
