The fitting protrusion 122b of the second component piece 122 is fitted into the fitting hole 121a of the first component piece 121, whereby the first component piece 121 and the second component piece 122 are positioned. . Thereby, the assembly | attachment improvement of the 1st component piece 121 and the 2nd component piece 122 is achieved.

  Further, as shown in FIG. 6, the first component piece 121 includes engagement pieces 121c at both ends thereof, while the second component piece 122 includes engagement pieces 122c at both end portions thereof as shown in FIG. It is supposed to be configured. In such a configuration, when the first component piece 121 and the second component piece 122 are assembled, the engagement piece 121c of the first component piece 121 and the engagement piece 122c of the second component piece 122 are integrated. Thus, it engages with an engaged region (not shown) on the head 110 side. Accordingly, the first component piece 121 and the second component piece 122 assembled to each other can be easily assembled at a predetermined position on the head 110 side while maintaining the assembled state. With regard to this configuration, the engagement piece 121c and the engagement piece 122c may be replaced with an engagement hole so that the engagement hole engages with an engaged region on the head 110 side.

As shown in FIG. 8, each saw-tooth part 129a is configured such that peaks and valleys extend in a direction intersecting the insertion direction and the insertion direction of the cleaning sheet with respect to the insertion port 125a. Each sawtooth portion 129a has a shape in which a peak and a valley are continuously repeated at a predetermined angle θ2 in FIG. 8, and the angle θ2 can be typically 90 degrees.

  Regarding the operation of the head 110 configured as described above, FIGS. 9 to 12 are referred to. 9, 10, and 12 are diagrams showing a cross-sectional structure of the locking member 120 in FIG. 3 with respect to the line BB, and the user's finger inserted into the insertion opening 125 a together with the cleaning sheet 200. A process in which the cleaning sheet 200 is locked to the locking member 120 in accordance with the insertion operation of F is shown. FIG. 11 shows a plan view of the locking member 120 in FIG.

  When the cleaning sheet 200 is attached to the head 110, as shown in FIG. 9, the user's finger F is inserted into the locking member 120 from above the cleaning sheet 200 that is wound around the head 110. It is inserted (pushed in) in the insertion direction (the direction of the white arrow in FIG. 9) toward the mouth 125a. Accordingly, the cleaning sheet 200 is inserted into the insertion space 125 together with the user's finger F. By this insertion operation, the user's finger F presses the extending wall 128 via the cleaning sheet 200, and the first component piece 121 and the second component piece 122 forming the insertion port 125a are shown in FIGS. As shown, the insertion opening 125a is expanded by elastically deforming against the elastic urging force in directions away from each other (in the direction of black arrows in FIGS. 10 to 11). In this embodiment, since the opening 127 is provided in particular, this elastic deformation is promoted and the insertion port 125a is easily expanded.

  Thereby, the slit interval of the sheet fixing slit 129 is expanded as shown in FIG. 10, and the slit interval of the sheet fixing auxiliary slit 126 is expanded as shown in FIG. At this time, the cleaning sheet 200 pushed into the insertion space 125 through the insertion opening 125a is in a state of entering the sheet fixing slit 129 and the sheet fixing auxiliary slit 126. Further, in the present embodiment, the extending walls 128, 128 of the first component piece 121 and the second component piece 122 are opposite to the base end portion 128a with the base end portion 128a on the insertion port 125a side as a support portion. Since the distal end portion 128b on the side is a free end, when the user's finger F inserted into the insertion space 125 is pressed in the separating direction, the distal end portion 128b easily moves in the separating direction about the proximal end portion 128a. To do. Thereby, since the load which acts on a user's finger | toe F by extension wall 128,128 can be restrained, in order to lock the cleaning sheet 200 reliably, the user can go deeper into the insertion space 125. The finger F can be inserted.

  Thereafter, the user's finger F once inserted into the insertion opening 125a is pulled out in the pulling direction (the direction of the white arrow in FIG. 12), whereby the pressing of the extending wall 128 is released. Thereby, the first component piece 121 and the second component piece 122 forming the insertion opening 125a attempt to return to the original shape as shown in FIG. 9 according to the elastic biasing force. At this time, the cleaning sheet 200 is slit. The sheet fixing slit 129 and the sheet fixing auxiliary slit 126 are closed while remaining in the space. Therefore, a state is formed in which the cleaning sheet 200 is sandwiched between the sheet fixing slit 129 and the sheet fixing auxiliary slit 126 (see FIG. 12). As a result, the cleaning sheet 200 disposed around the head 110 in a wrapping manner is locked by the locking member 120, and the mounting state of the cleaning sheet 200 with respect to the head 110 is maintained. At this time, it is preferable that the sheet fixing slit 129 is in a surface contact with all or a part of the sawtooth portion 129a so that the cleaning sheet 200 can be firmly fixed. Thereby, an appropriate holding force capable of preventing the cleaning sheet 200 from being detached from the head 110 during the wiping cleaning operation is maintained.

  As described above, in the present embodiment, the cleaning sheet 200 is locked by the slit portion including the sheet fixing slit 129 and the sheet fixing auxiliary slit 126 disposed in the connecting portion connected to the edge portion of the insertion space 125. Thus, by using the insertion space 125 itself, which is an area different from the slit portion, as an area in which the user's finger is inserted together with the cleaning sheet 200, the cleaning sheet 200 is surely secured via each locking member 120. Accordingly, it becomes possible to improve the mounting property of the cleaning sheet 200.

  Further, in the present embodiment, the locking member 120 is provided with an extending wall 128 extending in an inclined manner with respect to the sheet insertion direction of the cleaning sheet, and the extending wall 128 is provided along the sheet insertion direction of the cleaning sheet. Therefore, the cleaning sheet 200 can be easily sandwiched between the sheet fixing slit 129 and the user's finger F inserted together with the cleaning sheet 200 is fixed to the sheet. The configuration is such that it is difficult to be sandwiched between the slits 129.

  In the present embodiment, the sawtooth portions 129a of the first component piece 121 and the second component piece 122 have peaks and valleys extending in a direction intersecting the insertion direction and the insertion direction of the cleaning sheet 200 with respect to the insertion port 125a. Therefore, the cleaning sheet 200 once locked by the sheet fixing slit 129 is easily caught by each saw tooth portion 129a, and is effective in restricting the cleaning sheet 200 from coming out of the insertion port 125a. At this time, the cleaning sheet 200 locked to the sheet fixing slit 129 is also locked by the sheet fixing auxiliary slit 126 outside the insertion port 125a. Thereby, a stable locking force (holding force) of the cleaning sheet 200 by the locking member 120 is exhibited by the cooperation of the sheet fixing slit 129 and the sheet fixing auxiliary slit 126.

  In addition, the 1st component piece 121 and the 2nd component piece 122 of the said structure may be made into the separate structure which can be divided | segmented before an assembly | attachment, or may be made into an integral structure. For example, FIG. 13 shows an integrated structure in which the first component piece 121 and the second component piece 122 of the present embodiment are connected by a thin-walled connecting portion 121d. According to such a configuration, the first component piece 121 and the second component piece 122 are brought into an assembled state by being folded in the proximity direction at the connecting portion 121d.

  In the first component piece 121 and the second component piece 122 having the above-described configuration, the shape, number, position, and the like of the sheet fixing slit 129 and the sheet fixing auxiliary slit 126 can be appropriately changed as necessary. For example, the height and interval of the crests and troughs of the sawtooth portion 129a and the sawtooth portion 126a are different on the first component piece 121 side and the second component piece 122 side, the crest of one sawtooth portion and the trough of the other sawtooth portion. Is engaged, and the valley of one sawtooth part and the peak of the other sawtooth part are engaged, uneven shape below the sawtooth shape, fine uneven shape by surface treatment to roughen the surface roughness, embossed shape, etc. A configuration to be used can be appropriately adopted. FIG. 14 shows a cross-sectional structure of the first component piece 221 and the second component piece 222 of another embodiment. As shown in FIG. 14, it is possible to improve the locking force (holding force) of the cleaning sheet 200 by adopting a structure in which the sheet fixing auxiliary slits 126 are provided in two upper and lower stages.

  Next, a specific configuration of the pipe 130 will be described in detail with reference to FIGS. Here, FIG. 15 shows a cross-sectional structure of the pipe 130 in FIG. 1 that is brought into a pipe connection state by the connection portion 132 of the present embodiment. Further, FIG. 16 shows a cross-sectional structure of the pipe 130 in a pipe connection release state in which the pipe connection by the connection part 132 of this embodiment is released, and FIG. 17 shows the pipe 130 in FIG. Shown from the direction.

  As shown in FIGS. 15 to 17, the first pipe member 130 a is a so-called male pipe inserted into the pipe of the second pipe member 130 b in the connected state, while the second pipe member 130 a is a second pipe. The pipe member 130b is a so-called female pipe in which the first pipe member 130a is inserted into the pipe in the connected state. In this case, in the connecting portion of the first pipe member 130a and the second pipe member 130b, the inner diameter on the second pipe member 130b side is almost the same as the outer diameter on the first pipe member 130a side, or from the outer diameter. Is configured to be slightly larger. The first pipe member 130a and the second pipe member 130b are all made of a hard material, typically a metal material such as aluminum, stainless steel, and iron, and other than a metal material in order to form a pipe skeleton. The cylindrical member is made of a resin material or the like. The first pipe member 130a and the second pipe member 130b can adopt various shapes such as circles, ellipses, triangles, squares, trapezoids, polygons including regular hexagons, etc. as their cylindrical cross sections. Further, it is possible to appropriately select the pipe outer diameter and the pipe inner diameter. Here, the first pipe member 130a corresponds to the “first pipe member” in the present invention, and the second pipe member 130b here corresponds to the “second pipe member” in the present invention. .

  The connecting portion 132 has a function of connecting the first pipe member 130a and the second pipe member 130b.

  18 and 19 are referred to regarding the pipe connection operation and the pipe connection release operation by the connection part 132 of the pipe 130.

  FIG. 18 is a cross-sectional structural view of the pipe 130 according to the present embodiment, and shows a process of pipe connection operation by the connecting portion 132. In the pipe connection operation, first, the first pipe member 130a and the second pipe member 130b are arranged in abutting manner and are brought close to each other in the pipe extending direction, and the first pipe member 130b is placed inside the pipe. The member 130a is inserted. At this time, using the marks (marks 139 in FIG. 17) provided on the second engagement member 134 as described above, the positions of the engagement protrusions 136 of the first engagement member 133 and the marks of the second engagement member 134 are used. It is preferable that the first engagement member 133 and the second engagement member 134 are positioned with respect to each other so that the position of 139 substantially matches. As a result, the pipe connection operation by the connection part 132 of the pipe 130 can be facilitated, and particularly effective for the pipe connection operation when the number of the connection parts 132 is large. Then, as shown in FIG. 18, the engagement protrusion 136 of the first engagement member 133 is pressed toward the inside of the pipe by coming into contact with the tip end portion 134 a of the second engagement member 134, and its elastic biasing force is applied. Accordingly, it is pushed down toward the inside of the pipe around the support portion 136a.

  In the present embodiment, in particular, since the upper surface of the engagement protrusion 136 is inclined downward toward the pipe end surface 130c side of the first pipe member 130a, the pressing force by the distal end portion 134a of the second engagement member 134 is reduced. It will be smoothly converted into a pressing force of the engaging protrusion 136. In this case, the distal end portion 134 a of the second engagement member 134 preferably has a shape that follows the upper surface of the engagement protrusion 136. Thereby, the pushing-down operation of the engagement protrusion 136 is further smoothed.

  Thereafter, by further inserting the first pipe member 130a into the pipe of the second pipe member 130b, when the engagement protrusion 136 reaches the position of the engagement hole 137, the engagement protrusion 136 The inside of the engagement hole 137 moves to the outside of the pipe around the support portion 136a according to the elastic biasing force. Thus, when the engaging protrusion 136 is fitted into the engaging hole 137, the relative movement in the pipe extending direction of the first pipe member 130a and the second pipe member 130b is locked, as shown in FIG. A pipe connection state will be formed.

  On the other hand, FIG. 19 is a cross-sectional structure diagram of the pipe 130 of the present embodiment, and shows a process of releasing the pipe connection by the connecting portion 132. As shown in FIG. 19, in the pipe connection releasing operation, first, the pressing piece 138 is pressed to press down the engaging protrusion 136. By this pressing, the engaging protrusion 136 is pushed down below the engaging hole 137, and the engagement with the engaging hole 137 is released, so that the first pipe member 130a and the second pipe member 130b are disengaged. The lock related to the pipe extending direction is released, and a relative separation operation is enabled. Therefore, by pulling out the first pipe member 130a and the second pipe member 130b from each other, a pipe connection release state as shown in FIGS. 16 and 17 is formed. If necessary, the pressing piece 138 may be omitted, and the engaging protrusion 136 may be pushed down directly in the pipe connection releasing operation.

  In the first engagement member 133 configured as described above, the case where the elastic biasing force of the engagement protrusion 136 is realized by its own elastic structure has been described, but an elastic member may be provided separately. For example, FIG. 20 shows a cross-sectional structure of a first engagement member 233 of another embodiment that includes a leaf spring 240 that elastically biases the engagement protrusion 136. According to such a configuration, the elastic urging force of the engaging protrusion 136 can be applied by an elastic member such as the leaf spring 240 in addition to or in addition to its own elastic structure.

  In the above configuration, the first engagement member 133 includes the single engagement protrusion 136, and the second engagement member 134 includes the engagement hole 137 and the pressing piece 138 corresponding to the single engagement protrusion 136. Although the case has been described, a configuration in which the engagement protrusion (convex portion) on the second engagement member 134 side engages with the engagement hole (concave portion) on the first engagement member 133 side can also be used. A plurality of members corresponding to the engagement protrusion 136 can be provided. For example, FIG. 21 shows a cross-sectional structure of a first engagement member 333 according to another embodiment including two engagement protrusions 136, an engagement hole 137 and a pressing piece 138 corresponding to each of the two engagement protrusions 136. The cross-sectional structure of the second engagement member 334 according to another embodiment including the above is shown. According to such a configuration, it is possible to form a more reliable pipe connection state by increasing the number of fitting positions between the engagement protrusion 136 and the engagement hole 137.
