Description

Technical Field

[0001] The present invention relates to an attachment for a discharge port, and more particularly to an attachment that is installed and used at the discharge port of a foamed mixture discharge gun that discharges a foamed mixture.

Background Art

[0002] Conventionally, a foamed mixture discharge gun 301 that discharges a foamed mixture 311 (for example, a foamed mixture of a detergent, water, and air) generated by an air mixing type foaming machine toward an object to be cleaned is known (see FIG. 11). Note that the air mixing type foaming machine and the object to be cleaned are not shown in FIG. 11.

[0003] The foamed mixture discharge gun 301 includes a foamed mixture discharge gun main body 303, a joint with a filter 305, and a lance 307.

[0004] A hose 310 that supplies the foamed mixture 311 generated by the air mixing type foaming machine to the foamed mixture discharge gun main body 303 is connected to the foamed mixture discharge gun main body 303.

[0005] The joint with a filter 305 is connected to the discharge port (the discharge port of the foamed mixture) of the foamed mixture discharge gun main body 303, and the lance 307 is connected to the discharge port (the discharge port of the foamed mixture) of the joint with a filter 305. Further, the lance 307 is formed in an elongated cylindrical shape.

[0006] When the trigger 309 provided on the foamed mixture discharge gun main body 303 is operated, the foamed mixture 311 supplied to the foamed mixture discharge gun main body 303 and discharged from the discharge port of the foamed mixture discharge gun main body 303 is discharged as shown in FIG. 11.

[0007] More specifically, the foamed mixture 311 discharged from the discharge port of the foamed mixture discharge gun main body 303 flows through the inside of the joint with a filter 305 and the inside of the lance 307, and is discharged from the discharge port 313 at the tip of the elongated lance 307.

[0008] By directing the ejected foamy mixture 311 towards the object to be cleaned and hitting the object to be cleaned with it, the object to be cleaned is cleaned. Here, Patent Document 1 and Patent Document 2 can be cited as documents related to the prior art.

Summary of the Invention

Problems to be Solved by the Invention

[0010] By the way, in the foamy mixture ejection gun 301, the foamy mixture 311 is ejected vigorously from the discharge port 313 of the lance 307 in the same direction as the longitudinal direction of the lance 307. That is, the value of the solid angle of the foamy mixture 311 shown in FIG. 11 is small, and the ejection speed of the foamy mixture 311 from the discharge port 313 is quite high.

[0011] The faster the ejection speed of the foamy mixture 311 from the discharge port 313, the more the detachment of foreign substances (such as dust) from the object to be cleaned is promoted. However, if the ejection momentum of the foamy mixture 311 from the discharge port 313 is too strong, the usability may deteriorate.

[0012] For example, when the foamy mixture 311 is ejected towards the object to be cleaned, a strong bounce of the foamy mixture 311 hitting the object to be cleaned occurs. In this case, if there are other objects to be cleaned around the object to be cleaned, the bounced foamy mixture 311 may scatter to the other objects to be cleaned, and there is a risk of causing damage to other devices and the like.

[0013] Here, assume that a plurality of production lines are installed in a building such as a factory in a manner where they are close to each other, and one production line that is the object to be cleaned has stopped, while another production line adjacent to this one production line is operating.

[0014] When cleaning by hitting the foamy mixture 311 against the equipment (the object to be cleaned) of one stopped production line, the rebounding foamy mixture 311 may scatter to the area of other operating production lines. Such a situation should not occur due to circumstances such as the foamy mixture 311 containing a detergent.

[0015] An object of the present invention is to provide an attachment for a discharge port that can improve the usability of a foamy mixture discharge gun by controlling the discharge direction and the like of the foamy mixture discharged from the foamy mixture discharge gun.

MODE FOR CARRYING OUT THE INVENTION

[0026] As shown in Fig. 1, the attachment 1 for a discharge port which concerns on embodiment of this invention is installed in and used for the discharge port 7 of a foamy mixture discharge gun (foamy liquid agent discharge gun) 5 which discharges a foamy mixture (foamy mixture) 3. Further, as shown in Fig. 2, the attachment 1 for a discharge port is comprised including an attachment main-body part (attachment main body) 9 and a 1st discharge direction changing part (1st discharge direction changing piece) 11.

[0027] The foamy mixture 3 is, for example, a mixture of detergent, water, and air generated by an air-mixing type foaming machine 12. As the foamy mixture discharge gun 5, for example, the same one as the conventional foamy mixture discharge gun main body 303 is used. Also, as the air-mixing type foaming machine 12, for example, the same one as the conventional air-mixing type foaming machine is used. Further, as the foamy mixture discharge gun 5 and the air-mixing type foaming machine 12, for example, a product called SEKO's Pro Twin Form Kit is used.

[0028] The attachment main body 9 is formed in a cylindrical shape, and one opening (the first opening) serves as an inlet for the foamy mixture 3 discharged from the discharge port 7 of the foamy mixture discharge gun 5. One opening is connected directly or indirectly to the discharge port 7 of the foamy mixture in the foamy mixture discharge gun 5. And the foamy mixture 3 discharged from the discharge port 7 of the foamy mixture discharge gun 5 flows (moves) inside the cylinder of the attachment main body 9. Also, the other opening (the second opening) of the attachment main body 9 serves as the discharge port 13 of the foamy mixture 3.

[0029] The first discharge direction changing part 11 is installed at a part on the side of the other opening (the second opening) of the attachment main body 9. And at least a part (for example, almost all) of the traveling direction of the foamy mixture 3 discharged from the discharge port (the second opening of the attachment main body) 13 of the attachment main body 9 changes in the following direction.

[0030] That is, as shown in FIG. 9, the foamy mixture 3 travels in a direction that intersects the extending direction of the central axis of the cylindrical attachment main body 9 at a first angle and away from the attachment main body 9.

[0031] The extending direction of the central axis of the attachment main body 9 is the left - right direction in Fig. 9, which is the moving direction of the foamy mixture 3 within the attachment main body 9. The first angle, more precisely speaking, is a first - angle range, which includes an acute angle, a right angle, and an obtuse angle slightly larger than a right angle. Note that in some cases, the first - angle range may include an acute angle and a right angle but not an obtuse angle. Further, the foamy mixture 3 is configured to travel in a direction biased towards one side when viewed in the extending direction of the central axis of the cylindrical attachment main body 9. Each arrow in Fig. 9 indicates the moving direction of the foamy mixture 3.

[0032] The value of the length dimension (the left - right dimension in Fig. 3) of the cylindrical attachment main body 9 is sufficiently smaller than the value of the length dimension of the lance 307 of the conventional foamy - mixture discharge gun 301.

[0033] For example, as shown in Fig. 11, the value of the length dimension of the lance 307 of the foamy - mixture discharge gun 301 is larger than the maximum value of the outer - dimension of the foamy - mixture discharge gun main body 303, and is about 1.5 times to 4 times. The maximum value of the outer - dimension of the foamy - mixture discharge gun main body 303 is, for example, the value of the distance from the tip of the grip 315 of the foamy - mixture discharge gun main body 303 to the discharge port 313.

[0034] On the other hand, the value of the length dimension (the left - right dimension in Fig. 3) of the attachment main body 9 of the attachment 1 for the discharge port is equal to or less than the maximum value of the outer - dimension of the foamy - mixture discharge gun 5, and is about 0.2 times to 1 times. The value of the length dimension (the left - right dimension in Figs. 2(a)(b)) of the first discharge - direction changing portion 11 of the attachment 1 for the discharge port is also equal to or less than the maximum value of the outer - dimension of the foamy - mixture discharge gun 5, and is about 0.1 times to 1 times.

[0035] With the first discharge direction changing part 11 installed in the attachment main body part 9, the value of the length dimension of the attachment main body part 9 and the first discharge direction changing part 11 is equal to or less than the maximum value of the outer dimension of the foamed mixture discharge gun 5, and is about 0.2 times to 1 time. The maximum value of the outer dimension of the foamed mixture discharge gun 5 is, for example, the value of the distance from the tip of the grip 15 of the foamed mixture discharge gun 5 to the discharge port 7.

[0036] At least a part of the foamed mixture 3 discharged from the discharge port 13 of the attachment main body part 9 hits a part of the inner wall of the first discharge direction changing part 11 and changes the advancing direction, and is discharged from the discharge port 17 of the first discharge direction changing part 11. Further, even the foamed mixture 3 that is discharged from the discharge port 13 of the attachment main body part 9 and does not hit the inner wall of the first discharge direction changing part 11 hits the foamed mixture 3 that has hit the inner wall of the first discharge direction changing part 11 and bounced back, and changes the advancing direction.

[0037] Here, for the convenience of explanation, the discharge direction of the foamed mixture at the discharge port of the foamed mixture discharge gun is defined as the X direction (the first direction), a predetermined one direction orthogonal to the X direction is defined as the Y direction (the second direction), and the direction orthogonal to the X direction and the Y direction is defined as the Z direction.

[0038] The discharge direction of the foamed mixture 3 at the discharge port 7 of the foamed mixture discharge gun 5 is in the X direction and is a direction from one side of the X direction to the other side (the direction from right to left in FIGS. 2(a) and 2(b)). Also, the direction in which the foamed mixture 3 flows inside the attachment main body part 9 is also in the X direction and is a direction from one side of the X direction to the other side.

[0039] Note that by the discharge port attachment 1, the foamed mixture 3 discharged from the discharge port 7 of the foamed mixture discharge gun 5 changes the advancing direction by the first discharge direction changing part 11 at a place slightly away from the discharge port 13 of the attachment main body part 9 in the X direction.

[0040] The direction in which the foamy mixture 3 is advanced by the first discharge direction changing part 11 is defined as the first changed direction. As shown in FIG. 9, when the first angular range is an acute angle, when viewed in the Z direction, the first changed direction intersects obliquely with respect to the X direction and is a direction away from the discharge port 7 of the foamy mixture discharge gun 5.

[0041] When the first angular range is an obtuse angle slightly larger than a right angle, when viewed in the Z direction, the first changed direction intersects obliquely with respect to the X direction and is a direction approaching the discharge port 7 of the foamy mixture discharge gun 5. Also, when viewed in the X direction, the first changed direction is a direction from one side of the Y direction toward the other side.

[0042] However, since the discharged and advancing material is the foamy mixture 3, as already understood, not all of the foamy mixture 3 in the first changed direction has a parallel flow to each other. The discharge direction of the foamy mixture 3 (especially the discharge direction from the discharge port 17 of the first discharge direction changing part 11 of the attachment 1 for the discharge port) is, for example, fan-shaped (a fan shape with a small central angle acute angle) when viewed in the Z direction or the X direction and has a certain spread. To explain further, the value of the solid angle of the foamy mixture 3 discharged from the discharge port 17 of the first discharge direction changing part 11 is larger than the value of the solid angle of the foamy mixture 311 shown in FIG. 11.

[0043] The attachment main body part 9 is formed with a frustum of a cone shape on the outside and the internal space 19 is formed with a frustum of a cone shape smaller than the frustum of a cone on the outside. The central axes of the above two frustums of a cone coincide with each other.

[0044] The opening of the large circle of the frustum of a cone-shaped internal space 19 becomes the above-mentioned one opening (the inlet of the foamy mixture 3), and the opening of the small circle of the frustum of a cone-shaped internal space 19 becomes the above-mentioned other opening (the discharge port 13 of the foamy mixture 3).

[0045] As shown in Fig. 2(a), Fig. 4, etc., the first discharge direction changing part 11 is configured to include a cylindrical first discharge direction changing part main body 21 and an arc-shaped protruding part 23. The arc-shaped protruding part 23 is formed in a cylindrical shape and protrudes from one side of the first discharge direction changing part main body 21 by bending so as to draw an arc with an acute central angle from the opening.

[0046] No step is formed at the boundary between the inner wall of the cylinder of the first discharge direction changing part main body 21 and the inner wall of the cylinder of the arc-shaped protruding part 23, and the inner wall of the cylinder of the first discharge direction changing part main body 21 and the inner wall of the cylinder of the arc-shaped protruding part 23 are smoothly connected in a manner in which the shape of the surface changes.

[0047] First, on one plane, the arc-shaped protruding part 23 draws a double circle composed of a large-diameter circle and a small-diameter circle with their centers coinciding with each other, and a predetermined straight line tangent to the larger circle of the double circle. Subsequently, the double circle is rotated by an acute angle such as 60° around the predetermined straight line. At this time, the arc-shaped protruding part 23 has a three-dimensional shape represented by the locus of the rotation of the double circle.

[0048] In the first discharge direction changing part 11, the cross-sectional shape of the first discharge direction changing part main body 21 (the double circle of the cross-section by a plane perpendicular to the central axis of the cylinder) coincides with the shape of the double circle used in the description of the shape of the arc-shaped protruding part 23. Also, in the first discharge direction changing part 11, at the boundary between the first discharge direction changing part main body 21 and the arc-shaped protruding part 23, all of the double circles of the cylindrical first discharge direction changing part main body 21 and all of the double circles of the arc-shaped protruding part 23 overlap each other.

[0049] Furthermore, when the arc-shaped protruding part 23 rotates by an acute angle such as 60° around a predetermined straight line slightly separated from the double circle outside the large circle of the double circle, it may have a three-dimensional shape represented by the locus of the double circle.

[0050] The first discharge direction changing part 11 will be further described with a different expression while referring to FIG. 5. The first discharge direction changing part 11 is obtained by bending a cylindrical material 25 at a right angle, for example, at this intermediate part, and dividing the bent part at a right angle into two objects with a single plane 27 that is unfolded obliquely. Note that one of the two objects becomes the first discharge direction changing part 11.

[0051] As shown in FIG. 2, the first discharge direction changing part 11 is configured such that an attachment main body part 9 is inserted into a cylindrical first discharge direction changing part main body part 21, and an arc-shaped protruding part 23 protrudes from the attachment main body part 9 and is installed on the attachment main body part 9.

[0052] Also, as shown in FIGS. 2 and 8, the attachment 1 for the discharge port has a second discharge direction changing part (second discharge direction changing piece) 29. The second discharge direction changing part 29 is formed in a cylindrical shape and is installed on the first discharge direction changing part 11 (attachment main body part) 9 so as to conceal and cover the first discharge direction changing part 11.

[0053] The second discharge direction changing part 29 is configured to change the discharge direction of the foamy mixture 3 flowing in a direction (Y direction) orthogonal to the X direction among the foamy mixture 3 discharged from the discharge port 17 of the first discharge direction changing part 11 to the following direction. That is, the direction indicated by arrow A81 in FIG. 8 is changed to the direction indicated by arrow A82 in FIG. 8. Note that the direction orthogonal to the X direction includes directions that intersect at an obtuse angle or an acute angle close to a right angle.

[0054] The following direction described above for the second discharge direction changing part 29 is a direction that intersects the extending direction of the central axis of the cylindrical attachment main body part 9 at a second angle (second angle range; acute angle).

[0055] More specifically, the traveling direction of the foamy mixture 3 changed by the second discharge direction changing unit 29 is defined as the second changed direction. When viewed in the Z direction, the second changed direction intersects the extending direction of the central axis of the cylindrical attachment main body 9 at a second angle (second angle range; acute angle). Also, it is in the direction away from the attachment main body 9. When viewed in the X direction, the second changed direction is, similar to the first changed direction, a direction toward one side.

[0056] Also, the value of the solid angle of the foamy mixture 3 discharged from the discharge port 47 of the second discharge direction changing unit 29 is larger than the value of the solid angle of the foamy mixture 311 shown in FIG. 11. Further, it is slightly smaller than the value of the solid angle of the foamy mixture 3 discharged from the discharge port 13 of the first discharge direction changing unit 11 (see FIG. 9).

[0057] The value of the length dimension of the second discharge direction changing unit 29 of the attachment for the discharge port 1 is approximately the same as the value of the length dimension of the first discharge direction changing unit 11.

[0058] In the state where the first discharge direction changing unit 11 and the second discharge direction changing unit 29 are installed on the attachment main body 9, the value of the length dimension of the second discharge direction changing unit 29 or the like is equal to or less than the maximum value of the outer dimension of the foamy mixture discharge gun 5, and is about 0.3 times to 1 time.

[0059] As shown in FIG. 6, the second discharge direction changing unit 29 is formed in a cylindrical shape composed of a cylindrical space 31 with a large diameter and a cylindrical space 33 with a small diameter inside. And the cylindrical first discharge direction changing unit main body 21 of the first discharge direction changing unit 11 is inserted into the cylindrical space 33 with a small diameter. Also, all of the arc-shaped protruding portions 23 of the first discharge direction changing unit 11 enter into the cylindrical space 31 with a large diameter, and the second discharge direction changing unit 29 is configured to be installed on the first discharge direction changing unit 11 (attachment main body 9).

[0060] In addition, the attachment 1 for the discharge port is configured to include a stirring body 35 as shown in FIG. 7. The stirring body 35 is formed in a cylindrical shape. One opening (the first opening) of the stirring body 35 is directly connected to the discharge port 7 of the foamed mixture discharge gun 5, and the other opening (the second opening) is directly connected to the inlet of the foamed mixture 3 of the attachment main body 9.

[0061] That is, the stirring body 35 is installed between the foamed mixture discharge gun 5 and the attachment main body 9, and stirs the foamed mixture 3 flowing inside to make it more foamy. The value of the length dimension of the stirring body 35 is approximately the same as the value of the length dimension of the first discharge direction changing portion 11.

[0062] As shown in FIG. 7(a), the stirring body 35 includes a cylindrical stirring body main body 37 and a plurality of (for example, two) mesh-like members (for example, mesh-like filters) 39 formed in a plate shape with fine meshes.

[0063] The plurality of mesh-like members 39 are installed in the internal space of the cylindrical stirring body main body 37 at a predetermined interval in the extending direction of the axis of the cylindrical stirring body main body 37 so that their thickness directions coincide with the extending direction of the axis of the cylindrical stirring body main body 37. All of the foamed mixture 3 flowing through the internal space of the cylindrical stirring body main body 37 is configured to pass through the mesh-like member 39.

[0064] The first discharge direction changing portion 11 is made of a material such as synthetic rubber and thus has elasticity. When the foamed mixture (the foamed mixture discharged in the form of turbulent flow) 3 discharged from the attachment main body 9 hits, the hit portion and the vicinity thereof are configured to repeatedly perform slight elastic deformation and restoration in a short cycle.

[0065] On the other hand, the attachment main body 9 other than the first discharge direction changing portion 11 and the second discharge direction changing portion 29 are made of a synthetic resin having high rigidity (rigidity that can be regarded as a rigid body in the present invention), so it hardly repeats the above-mentioned elastic deformation and restoration.

[0066] Here, the attachment 1 for the discharge port will be described in more detail.

[0067] As shown in FIG. 1, the foamed mixture discharge gun 5 is connected to the air mixing type foaming machine 12 by a flexible pipe member 41, and is configured to receive the supply of the foamed mixture 3 from the air mixing type foaming machine 12.

[0068] The attachment 1 for the discharge port is installed on the foamed mixture discharge gun 5. When the operation part 43 of the foamed mixture discharge gun 5 is rotated as indicated by the arrow while the air mixing type foaming machine 12 is operating, the foamed mixture 3 is discharged from the attachment 1 for the discharge port.

[0069] Also, as shown in FIG. 3, on one end of the attachment main body part 9, a male screw part 45 is formed, and a female screw part (not shown) is provided at the discharge port 7 of the foamed mixture discharge gun 5. Further, although not shown in the stirring body 35, a screw part is appropriately provided.

[0070] Then, by the above screw parts, the stirring body 35 is integrally installed on the foamed mixture discharge gun 5, and the attachment main body part 9 is integrally installed on the stirring body 35. When the stirring body 35 is not used, the male screw part 45 of the attachment main body part 9 is screwed into the female screw part of the foamed mixture discharge gun 5, so that the attachment main body part 9 is integrally installed on the foamed mixture discharge gun 5.

[0071] As shown in FIG. 2, when the first discharge direction changing part 11 and the second discharge direction changing part 29 are installed on the attachment main body part 9, the end part of the first discharge direction changing part main body part 21 is elastically deformed being sandwiched between the attachment main body part 9 and the second discharge direction changing part 29. Then, by the biasing force of the first discharge direction changing part 11, the attachment main body part 9, the first discharge direction changing part 11, and the second discharge direction changing part 29 are integrated.

[0072] Also, when looking at the attachment 1 for the discharge port from the other side towards one side in the X direction, as shown in Fig. 2(c), the discharge port 17 of the first discharge direction changing portion 11 enters inside the discharge port 47 of the second discharge direction changing portion 29, and the entire discharge port 17 is visible. Further, through the discharge port 17, the lower part of the discharge port 13 of the attachment main body portion 9 is visible, and the upper part is hidden by the first discharge direction changing portion 11.

[0073] Next, the operations of the air mixing type foaming machine 12 shown in Fig. 1 and the foamed mixture discharge gun 5 with the attachment 1 for the discharge port installed thereon will be described.

[0074] In the initial state, assume that the air mixing type foaming machine 12 is operating, but the foamed mixture 3 is not being discharged from the foamed mixture discharge gun 5.

[0075] In the above initial state, when the operation portion 43 of the foamed mixture discharge gun 5 is rotated in the direction indicated by the arrow, the foamed mixture 3 is discharged from the foamed mixture discharge gun 5, and the foamed mixture 3 is discharged from the attachment 1 for the discharge port.

[0076] In the attachment 1 for the discharge port, the foamed mixture 3 discharged from the discharge port 13 of the attachment main body portion 9 by the first discharge direction changing portion 11 advances in a direction intersecting the extending direction of the central axis of the cylindrical attachment main body portion 9 at a first angle.

[0077] Also, in the attachment 1 for the discharge port, the foamed mixture 3 discharged from the discharge port 13 of the attachment main body portion 9 by the first discharge direction changing portion 11 advances in a direction away from the attachment main body portion 9.

[0078] Furthermore, in the attachment 1 for the discharge port, the foamed mixture 3 discharged from the discharge port 13 of the attachment main body portion 9 by the first discharge direction changing portion 11 advances in a direction towards one side when viewed in the extending direction of the central axis of the cylindrical attachment main body portion 9.

[0079] As a result, the ejection direction of the foamy mixture 3 ejected from the foamy mixture ejection gun 5 is controlled, and the usability of the foamy mixture ejection gun 5 can be improved.

[0080] By controlling the ejection direction of the foamy mixture 3 ejected from the foamy mixture ejection gun 5, for example, the rebounding direction of the foamy mixture 3 hitting the object to be cleaned can be controlled, and other equipment etc. other than the object to be cleaned can be prevented from being soiled.

[0081] Also, assume that in a building such as a factory, a plurality of production lines are installed in a manner that they are close to each other, and one production line is stopped because it is the object to be cleaned, and another production line adjacent to this one production line is operating.

[0082] In this case, when hitting the equipment (object to be cleaned) of one stopped production line with the foamy mixture, it is possible to prevent the splashing of the rebounding foamy mixture to the place of another operating production line.

[0083] Furthermore, the value of the longitudinal dimension of the attachment 1 for the discharge port is small, and the moving direction of the foamy mixture 3 ejected from the discharge port 7 of the foamy mixture ejection gun 5 is changed by the attachment 1 for the discharge port. As a result, the momentum of the foamy mixture 3 ejected from the discharge port of the attachment 1 for the discharge port is weakened, and this also can improve the usability of the foamy mixture ejection gun 5.

[0084] Also, the value of the length dimension of the attachment 1 for the discharge port is sufficiently smaller than the value of the length dimension of the lance 307 of the conventional foamy mixture ejection gun 301. Thereby, the handling of the foamy mixture ejection gun 5 provided with the attachment 1 for the discharge port becomes easier, and the usability is improved.

[0085] In addition, in the attachment 1 for the discharge port, the first discharge direction changing portion 11 has the attachment main body portion 9 inserted into the cylindrical first discharge direction changing portion main body portion 21. Further, the arc-shaped protruding portion 23 protrudes from the attachment main body portion 9 and is configured to be installed on the attachment main body portion 9. Thereby, the value of the length dimension of the attachment 1 for the discharge port can be further reduced, and the usability can be further improved.

[0086] In addition, the attachment main body portion 9 and the first discharge direction changing portion 11 are configured separately. Thereby, the adjustment of the rotation angle of the first discharge direction changing portion 11 with respect to the foam mixture discharge gun 5 (attachment main body portion 9) becomes easy, and the discharge direction of the foam mixture 3 (the discharge direction when viewed in the X-axis direction) can be easily adjusted.

[0087] In addition, in the attachment 1 for the discharge port, the second discharge direction changing portion 29 is installed on the first discharge direction changing portion 11 (attachment main body portion 9) so as to hide and cover the first discharge direction changing portion 11. Thereby, the configuration of the first discharge direction changing portion 11 is less visible from the outside of the attachment 1 for the discharge port, and imitation when a third party views the attachment 1 for the discharge port can be prevented.

[0088] In addition, in the attachment 1 for the discharge port, the second discharge direction changing portion 29 changes the discharge direction of the foam mixture 3 flowing in a direction orthogonal to the X direction among the foam mixture 3 discharged from the first discharge direction changing portion 11.

[0089] That is, the second discharge direction changing portion 29 changes the discharge direction of the foam mixture 3 flowing in the above-described orthogonal direction to a direction intersecting at a second angle with respect to the extending direction of the central axis of the cylindrical attachment main body portion 9.

[0090] Thus, for example, when using the foamy mixture discharge gun 5 with the attachment 1 for the discharge port, with the horizontal direction of the paper surface in FIG. 2(a) being the horizontal direction, the following occurs. That is, the splashing downward of the foamy mixture 3 coming out from the discharge port 13 of the first discharge direction changing part 11 of the attachment 1 for the discharge port is eliminated, and the usability of the foamy mixture discharge gun 5 is further improved.

[0091] Further, in the attachment 1 for the discharge port, the second discharge direction changing part 29 is formed in a cylindrical shape and is configured to be installed in the first discharge direction changing part 11 (attachment main body part 9). Thereby, the installation of the second discharge direction changing part 29 is facilitated, and the first discharge direction changing part 11 can be accurately hidden.

[0092] Also, in the attachment 1 for the discharge port, the stirring body 35 stirs the foamy mixture 3 flowing inside it to further foam it. Thereby, foam (foamy mixture 3) like high-quality shaving cream can be discharged from the attachment 1 for the discharge port.

[0093] Also, the stirring body 35 can weaken the momentum of the foamy mixture 3 discharged from the discharge port of the attachment 1 for the discharge port.

[0094] Also, in the attachment 1 for the discharge port, the stirring body 35 includes a cylindrical stirring body main body part 37 and a fine mesh-like member 39 and is formed in a plate shape. Thereby, a foamy mixture 3 like high-quality shaving cream can be obtained with a simple configuration.

[0095] Also, in the attachment 1 for the discharge port, the first discharge direction changing part 11 has elasticity, and the foamy mixture 3 discharged from the attachment main body part 9 is configured to collide. And the collided part and the part in the vicinity thereof are configured to repeatedly perform slight elastic deformation and restoration in a short cycle.

[0096] As a result, the momentum of the foamy mixture 3 discharged from the discharge port of the attachment 1 for the discharge port can be further weakened.

[0097] In addition, since the first discharge direction changing portion 11 made of synthetic rubber is covered with the second discharge direction changing portion 29 made of a synthetic resin with high rigidity, the easily damaged first discharge direction changing portion 11 is protected.

[0098] By the way, as shown in Fig. 10(a), the attachment 1 for the discharge port may be configured integrally with the attachment main body portion 9, the first discharge direction changing portion 11, and the second discharge direction changing portion 29. As a result, the attachment 1 for the discharge port can be easily and quickly attached to and detached from the foamy mixture discharge gun 5. Note that the attachment 1 for the discharge port shown in Fig. 10(a) is made of a high-rigidity constituent resin or the like.

[0099] In addition, as shown in Fig. 7(b), the stirring body main body portion 37 of the stirring body 35 may be divided into several (for example, two) parts. In this case, one mesh-like member 39 will be provided on one stirring body main body portion 37.

[0100] In addition, as shown in Fig. 9, the second discharge direction changing portion 29 may not be used. Furthermore, the stirring body 35 may be deleted and not used. Also, when the second discharge direction changing portion 29 is not used, as shown in Fig. 10(b), the attachment main body portion 9 and the first discharge direction changing portion 11 may be configured integrally.

[0101] By the way, the above-described attachment 1 for the discharge port is provided with a discharge port for discharging a foamy mixture and is installed in a foamy mixture discharge gun, so as to weaken the momentum of the discharge of the foamy mixture from the discharge port, and in a state where the foamy mixture discharge gun is discharging the foamy mixture horizontally from this discharge port, the discharge direction of the foamy mixture from the discharge port is directed downward to efficiently apply the foamy mixture to the object to be washed. This is an example of an attachment for the discharge port that changes the discharge direction of the foamy mixture discharged from the discharge port to a predetermined direction (first changed direction) different from the discharge direction of the foamy mixture at the discharge port of the foamy mixture discharge gun.
