Problems to be solved by the invention

[0004] However, since the above-mentioned Patent Document 1 simply fixes the wire to a square cleaning cloth, the cleaning cloth becomes irregular when the cleaning cloth is inserted into the pipe to be cleaned through the wire. Can be bent by bending force ¾. In addition, due to this stain, the cleaning cloth did not come into surface contact with the entire inner peripheral surface of the pipe to be cleaned, and the dirt attached to the inner peripheral surface of the pipe to be cleaned could not be removed sufficiently. In addition, when cleaning with a brush as in Patent Document 2, the brush bristles and the inner peripheral surface of the pipe to be cleaned are almost in point contact, so it is difficult to reliably remove dirt. Had. Moreover, in the instrument shown in Patent Document 3, the protrusion and the inner peripheral surface of the pipe to be cleaned However, it may not be possible to sufficiently remove the dirt adhering to the inner peripheral surface of the pipe to be cleaned, which has a contact area of a point contact or a line contact, and the inner diameter of the pipe to be cleaned If it is smaller, the cleaning ability is remarkably lowered, and there is a problem that the usable range is limited by the inner diameter of the pipe to be cleaned. This also applies to the brush of Patent Document 2. Furthermore, the instrument shown in Patent Document 3 has a problem that if the inner diameter of the pipe to be cleaned changes midway, it cannot cope with this change.

[0005] And, if the filth is not sufficiently removed, it becomes unsanitary. Especially, in the case of an endoscope or the like that is inserted into the human body, the filth is not sufficiently removed. It could cause infections.

[0006] Therefore, the present invention solves the above-described problems by removing dirt by bringing a cleaning tool for cleaning the inside of the pipe to be cleaned into surface contact with the inner peripheral surface of the pipe to be cleaned. Therefore, it is possible to clean the inner peripheral surface of the pipe to be cleaned without omission and to use it without being strictly bound by the size of the inner diameter of the pipe to be cleaned. Moreover, even if the inner diameter of the pipe to be cleaned changes in the middle of the inlet and outlet, it is intended to make it possible to remove dirt in response to this change.

Means for solving the problem

[0007] Therefore, in order to solve the above-described problems, the first invention of the present invention is a soft elastic wire rod for insertion into a pipe to be cleaned for cleaning purposes, and a width diameter at least equal to or larger than the inner peripheral diameter of the pipe to be cleaned. It is formed in a strip shape, parallel to the axial direction of the wire rod or inclined in the axial direction and arranged in the length direction, and at one end, the outer periphery of the wire rod is covered and fixed on both sides. It consists of a cleaning cloth that is not fixed to the wire at the other end opposite to the section, and the wire is inserted into the end of the pipe to be cleaned from the direction of the covering and fixing section. When the cleaning cloth is pulled into the pipe to be cleaned by pulling it from the end, the cleaning cloth is drawn into the cleaning pipe while covering the outer periphery of the wire, so that the outer peripheral surface of the cleaning cloth and the inner peripheral surface of the cleaning pipe To remove dirt.

[0008] In addition, the second invention of the present invention has a strip shape in which the soft elastic one and other wire rods to be inserted into a cleaning pipe for cleaning and the width diameter are at least equal to or larger than the inner peripheral diameter of the pipe to be cleaned. The length direction is arranged parallel to or incline in the axial direction of one of the wire rods, and is fixed at one end. The outer periphery of the other wire is covered and fixed on both sides, and the other end on the opposite side of the covering fixing part is covered with the outer periphery of the other wire separate from the one wire. The distance between one end and the other end of the cleaning cloth consists of one and the other wire and the non-fixed cleaning cloth. When the cleaning cloth is drawn into the pipe to be cleaned by pulling the other or the other wire of the pipe to be cleaned and pulling the cleaning cloth into the pipe to be cleaned, the cleaning pipe covers the outer circumference of the one or the other wire. By pulling in, the outer peripheral surface of the cleaning cloth and the inner peripheral surface of the pipe to be cleaned come into contact with each other to remove dirt, and the other or one wire is pulled to clean one end of the pipe to be cleaned. The cloth can be pulled back.

[0009] In addition, the third invention of the present invention is a soft elastic wire rod for insertion into a tube to be cleaned for cleaning purposes, a width diameter at least equal to or greater than the inner peripheral diameter of the tube to be cleaned, formed into a strip shape, The length direction is arranged in parallel to the axial direction or inclined in the axial direction, and the outer periphery of the wire is covered and fixed at both ends with one end and cleaned at the other end opposite to the covering fixing portion. A pull-back thin wire is attached for pulling back the internal force of the pipe. The distance between this bow I return thin wire and the wire is composed of a wire and a cleaning cloth that is not fixed to the pull-back wire. When the wire is inserted from the direction of the sheath fixing part, the wire is pulled from the other end of the pipe to be cleaned, and the cleaning cloth is drawn into the pipe to be cleaned, the cleaning cloth covers the outer periphery of the wire and the object is cleaned. By being drawn into the pipe, the outer peripheral surface of the cleaning cloth and the inner peripheral surface of the pipe to be cleaned come into contact with each other to remove dirt. Together, in which the cleaning cloth at one end of the cleaning tube by pulling the pull-back thin wire for pullback was possible pullback.

[0010] Further, one cleaning cloth may be disposed on the wire.

[0011] In addition, a plurality of cleaning cloths may be arranged at a plurality of locations of the wire with a predetermined interval.

[0012] In addition, the cleaning cloth may be a plurality of cleaning cloths arranged at a plurality of positions of the wire rod, with the direction of the joint portion of each covering fixing portion being shifted in the circumferential direction.

[0013] In addition, the cleaning cloth may have a tapered end at one end that is covered and fixed to the wire.

[0014] The cleaning cloth may be made of microfiber! /. [0015] In addition, the cleaning cloth may be arranged in such a manner that both side portions in the length direction are overlapped in a state where the cleaning cloth is drawn into the pipe to be cleaned.

[0016] The other or one of the wires may be one that pulls the cleaning cloth back to one end side of the pipe to be cleaned when the cleaning cloth is clogged in the pipe to be cleaned.

[0017] Further, the pullback thin wire for pulling back may be attached by being inserted into an insertion hole formed in the other end of the cleaning cloth.

[0018] The pull-back thin line for pull-back may be one that pulls the cleaning cloth back to one end side of the pipe to be cleaned when the cleaning cloth is clogged in the pipe to be cleaned.

[0019] Further, the covering fixing portion covers the outer periphery with a heat-shrinkable protective cap, and heat-shrinks the protective cap to fasten and fix the cleaning cloth to the wire. It may be possible to prevent the dropout.

[0020] In addition, the pull-back thin wire inserted through the insertion hole connects and fixes the tip portion and the main body portion that penetrate the penetration hole with a metal fixing member, and the fixing member is covered with a soft elastic cover tube. By covering, it may be possible to prevent damage to the inner surface of the pipe to be cleaned by the fixing member.

The invention's effect

[0021] In the first invention, which is configured as described above, the wire is inserted from one end of the pipe to be cleaned by fixing one end of the cleaning cloth to the wire, and the cleaning cloth is placed in the pipe to be cleaned. The cleaning cloth covers the outer circumference of the wire rod when it is drawn into the cylinder, and is wound into a cylindrical shape to match the shape of the inner peripheral surface of the pipe to be cleaned. In this state, the cleaning cloth is drawn into the pipe to be cleaned. It is. As a result, the cleaning cloth can come into surface contact along the shape of the inner peripheral surface of the pipe to be cleaned, and dirt attached to the inner peripheral surface of the pipe to be cleaned can be removed over a wide area of the cleaning cloth.

[0022] Further, since the cleaning cloth can be deformed in the circumferential direction, it can be widely used even when the inner diameter of the pipe to be cleaned is slightly different. In addition, even if the inner diameter of the pipe to be cleaned changes in the middle of the inlet and outlet, the cylindrical diameter formed by the cleaning cloth is deformed in response to this change, and along the inner peripheral surface of the pipe to be cleaned. The surface can be contacted. In addition, since the cleaning cloth is deformed into a cylindrical shape along the inner peripheral surface of the pipe to be cleaned, it is less likely to cause wrinkles due to irregular deformation. In addition, even if a crease is generated in a part, the front of the crease Since the subsequent cleaning cloth comes into surface contact with the inner peripheral surface of the pipe to be cleaned, there is no wiping residue.

[0023] Further, in the second invention, one or the other wire fixed to the other end of the cleaning cloth in a state where the cleaning cloth is inserted from one end of the pipe to be cleaned into the covering fixing section. When is pulled, the cleaning cloth can be pulled back to one end side of the pipe to be cleaned. Similarly, in the third invention, when the cleaning cloth is inserted from one end of the pipe to be cleaned into the inside from the direction of the covering fixing portion, a pulling back thin line attached to the other end of the cleaning cloth is drawn. The cleaning cloth can be pulled back to one end of the pipe to be cleaned. Therefore, in the second and third inventions, for example, the cleaning cloth inserted into the pipe to be cleaned is caught or clogged in the middle of the pipe to be cleaned for some reason, and the other end side of the pipe to be cleaned is In the unlikely event that force cannot be withdrawn, pull the cleaning cloth back to one end of the pipe to be cleaned by drawing one or the other wire or the pulling back thin line, and clean the inside of the pipe to be cleaned again. Can do.

Example 1

[0026] Hereinafter, Example 1 according to the first invention will be described with reference to the drawings. (1) is a wire using a soft elastic material, and is a cleaning object as shown in FIG. It has the strength and flexibility to be inserted into the cleaning pipe (2) of a scope, wind instrument, etc., and easily penetrated from one end (3) to the other end (4) of the cleaning pipe (2). is there. Then, one end (7) of one cleaning cloth (6) for cleaning the inner peripheral surface (5) of the pipe to be cleaned (2) as shown in Fig. 1 is covered and fixed to the wire (1), Covering fixing part (8). This cleaning cloth (6) is made of microfiber and has a strip shape, the width of which is equal to or greater than the inner circumference of the pipe to be cleaned (2), and the other end (9) on the opposite side of the covering fixing part (8). Is not fixed to the wire (1).

[0027] In addition, the covering and fixing of the cleaning cloth (6) to the wire rod (1) is performed by arranging the length direction of the cleaning cloth (6) parallel to the axial direction of the wire rod (1) as shown in FIG. In this state, the outer periphery of the wire rod (1) is covered and fixed to the outer periphery of the wire rod (1) with one end portion (7) of the cleaning cloth (6). Then, the part continuing to the covering fixing part (8) forms the conical part (10). The cleaning cloth (6) has a diameter of the covering fixing part (8) including the wire (1) when the wire (1) is covered, for example, by tapering one end (7) as shown in Fig. 2. It is preferable that the conical portion (10) is easy to be formed while not increasing.

[0028] The width of the cleaning cloth (6) is preferably equal to or larger than the inner peripheral diameter of the pipe to be cleaned (2). If it is slightly larger than the circumference, the side parts (14) in the length direction of the cleaning cloth (6) will come into contact with each other without overlapping, and the expansion pressure in the direction of the inner circumference (5) of the pipe to be cleaned (2) And adheres closely to the inner peripheral surface (5). Therefore, the dirt adhering to the inner peripheral surface (5) of the pipe to be cleaned (2) can be reliably removed with the cleaning cloth (6). [0029] Further, if the width of the cleaning cloth (6) is larger than the inner peripheral diameter of the pipe to be cleaned (2) than in the above embodiment, the cleaning cloth (6) is placed in the pipe to be cleaned (2). When entering, the cleaning cloth (6) in the lengthwise direction (14) is overlapped, and the cleaning cloth (6) in the overlapped area generates a contact friction force between them, and the cleaning cloth (6) The cylindrical holding force becomes stronger. Therefore, since the outer peripheral surface (11) of the cleaning cloth (6) is firmly attached to the inner peripheral surface (5) of the pipe to be cleaned (2), the dirt adhering to the inner peripheral surface (5) is removed from the cleaning cloth (6). Can be removed reliably. At this time, even if the cleaning cloth (6) has a small amount of stains, even if a part of the cleaning cloth (6) is stained, the cleaning cloths (6 ) Comes into surface contact with the inner peripheral surface (5) of the pipe to be cleaned (2), so that the dirt on the inner peripheral surface (5) can be reliably removed. Further, since the cleaning cloth (6) is the one in which both side portions (14) in the longitudinal direction are simply in contact with each other, the diameter can be easily deformed by changing the overlapping amount. Therefore, when the width of the cleaning cloth (6) is set in this way, even if the inner diameter of the pipe to be cleaned (2) changes between one end (3) and the other end (4), this change can be accommodated. It will be possible.

[0030] If the width of the cleaning cloth (6) and the inner peripheral diameter of the pipe to be cleaned (2) are equal, the cleaning cloth (6) Since the side portions (14) in the length direction of 6) are in contact with each other, the outer peripheral surface (11) of the cleaning cloth (6) is in contact with the entire inner peripheral surface (5) of the pipe to be cleaned (2). It is possible to remove the dirt adhering to the inner peripheral surface (5) of the pipe to be cleaned (2), but compared with the case where the side (14) of the cleaning cloth (6) is in contact with or overlapped. The expansion pressure on the inner peripheral surface (5) of the pipe to be cleaned (2) is small.

[0031] When the width of the cleaning cloth (6) is smaller than the inner peripheral diameter of the pipe to be cleaned (2), the outer peripheral surface (11) of the cleaning cloth (6) becomes the inner peripheral face of the pipe to be cleaned (2). When the cleaning cloth (6) is inserted and contacted, the side parts (14) in the length direction of the cleaning cloth (6) do not come into contact with each other, leaving unwiped parts and a small cylindrical holding force for the cleaning cloth (6) Thus, sufficient pressure in the direction of the inner peripheral surface (5) of the pipe to be cleaned (2) cannot be obtained, and the dirt attached to the inner peripheral surface (5) cannot be sufficiently removed.

[0032] In the case formed as described above, the wire (1) was inserted from one end (3) of the pipe to be cleaned (2), and the other end (4) force of the pipe to be cleaned (2) was also generated. When the wire rod (1) is pulled out, the cleaning cloth (6) is drawn into the pipe to be cleaned (2) from the covering fixing portion (8) side together with the wire rod (1) as shown in FIG. As a result of this pull-in, the conical part (10) that continues to the covering fixing part (8) of the cleaning cloth (6) is also cleaned while the unfixed part of the tip is in the shape of the inner periphery of the pipe to be cleaned (2). Enter the pipe (2). this To the cleaning pipe (2) with the outer peripheral surface (11) of the cleaning cloth (6) and the inner peripheral surface (5) of the pipe to be cleaned (2) in surface contact, and the pipe to be cleaned (2) The dirt adhering to the inner peripheral surface (5) can be removed by wiping with a cleaning cloth (6).

[0033] In the present embodiment, the cleaning cloth (6) is covered and fixed to the wire (1) in a state where the axial direction of the wire (1) and the length direction of the cleaning cloth (6) are arranged in parallel. In another embodiment, the length of the cleaning cloth (6) is inclined with respect to the axial direction of the wire (1), and one end of the cleaning cloth (6) ( It is also possible to cover and fix 7) on the outer periphery of the wire (1) from both sides. In this case, when the cleaning cloth (6) together with the wire (1) is drawn into the pipe to be cleaned (2), the joint (12) of the covering fixing part (8) of the cleaning cloth (6) is slightly spiraled. Enter the sweep tube (2) with overlapping shapes.

Then, the side end face (13) of the cleaning cloth (6) comes into line contact with the inner peripheral face (5) of the pipe to be cleaned (2), and the side end face (13) of the cleaning cloth (6). Due to the edge effect, dirt adhered firmly to the inner peripheral surface (5) can be scraped off. Similarly to the case where the axial direction of the wire (1) and the length direction of the cleaning cloth (6) are arranged in parallel, the outer peripheral surface (11) of the cleaning cloth (6) other than the side end face (13). ) And the inner peripheral surface (5) of the pipe to be cleaned (2) are in surface contact with the pipe to be cleaned (2) to remove dirt adhering to the inner peripheral surface (5) of the pipe to be cleaned (2). Can be wiped off with a cleaning cloth (6).

Example 2

[0035] In the first embodiment, the cleaning cloth (6) covered with the wire (1) is described as one sheet. In Example 2, the cleaning cloth (6) is two sheets. I will explain things. In this case, two cleaning cloths (6) as shown in Fig. 4 are placed at two locations on the wire (1) at regular intervals, and the outer periphery of the wire (1) is covered on both sides. Fix it. By covering and fixing the two cleaning cloths (6) to the wire (1) in this way, the outer peripheral surface (11) of the cleaning cloth (6) and the pipe to be cleaned (2 ) Increases the contact area with the inner peripheral surface (5). Therefore, even if the cleaning cloth (6) that first entered the pipe to be cleaned (6) has enough power to remove the dirt, it can be removed with the following cleaning cloth (6), and the removal of dirt is more reliable. Can be made.

In this embodiment, as described above, the two cleaning cloths (6) are covered and fixed to the outer periphery of the wire rod (1), but in other different embodiments, the cleaning cloth (6) Of course, if necessary, three or more sheets can be fixed to the outer periphery of the wire (1) with a certain interval. Again in this case Similarly, the increase in the contact area makes it possible to more reliably remove the dirt adhering to the inner peripheral surface (5).

[0037] In addition, the direction of the joint portion (12) of the covering fixing portion (8) of the cleaning cloth (6) is shifted in the circumferential direction of the wire (1) as shown in FIG. Cover and fix the cloth (6) to the wire (1). As a result, the covering and fixing of the cleaning cloth (6) to the wire rod (1) is more complicated than in the case of Example 1 above, but when the cleaning cloth (6) advances in the pipe to be cleaned (2). In addition, in the unlikely event that dirt remains on the inner peripheral surface (5) of the pipe to be cleaned (2) at the contact portion between the lengthwise sides (14) of the cleaning cloth (6) When the outer peripheral surface (11) of the succeeding cleaning cloth (6) with the eyes (12) shifted in the circumferential direction of the wire rod (1) comes into contact with this unwiped area, the remaining dirt can be removed. This makes it possible to more reliably remove filth.

Example 3

[0038] Further, in Examples 1 and 2, the other end (9) of the cleaning cloth (6) is not fixed to the wire (1). Example 3 is one end of the cleaning cloth (6). (7) is formed separately from one wire (la), and the other wire (lb) of the same material as this one (la) is attached to the other end (9) of the cleaning cloth (6). , Fixed in the same way as one wire (la). Specifically, as shown in Fig. 5, the axial direction of one wire rod (la) fixed to one end (7) of the cleaning cloth (6) is parallel to the length direction of the strip-shaped cleaning cloth (6). In this state, the outer periphery of one wire rod (la) is covered and fixed with one end (7) of the cleaning cloth (6). In addition, the axial direction of the other flexible wire (lb) formed separately from one wire (la) is arranged parallel to the length direction of the cleaning cloth (6), and the other end of the cleaning cloth (6) is arranged. Cover the outer circumference of the other wire (lb) with part (9) and cover it with both side forces. The distance between one end (7) and the other end (9) of the cleaning cloth (6) is not fixed to one wire (la) and the other wire (lb).

[0039] In the configuration as described above, the configuration is slightly more complicated than in the case of Examples 1 and 2, but one wire rod (la) is connected to one end of the pipe to be cleaned (2) ( The cleaning effect of inserting the cleaning cloth (6) into the pipe to be cleaned (2) by inserting it from 3) and pulling this one wire (la) from the other end (4) of the pipe (2) to be cleaned The same effects as in the first embodiment are obtained. However, if for some reason during this cleaning process, one of the wires (la) or the cleaning cloth (6) force S in the pipe to be cleaned (6) force S In the event that it becomes impossible to pull out the other end (4) side force of 2), the other wire (lb) covered and fixed to the other end (9) of the cleaning cloth (6) The cleaning cloth (6) can be pulled back to one end (3) side of the pipe to be cleaned (2) by pulling the part of the pipe to be cleaned (2) that protrudes to the outside in the pullback direction. Therefore, for example, the cleaning cloth (6) pulls against obstacles such as dirt that has become solid in the pipe to be cleaned (2), so that one wire rod (la) is attached to the other of the pipe to be cleaned (2). This is effective when the cleaning cloth (6) cannot be pulled out even when pulled from the end (4).

[0040] Further, the distance between the one end (7) and the other end (9) of the cleaning cloth (6) is different from that of one wire (la) and the other wire (lb) as shown in FIG. As described above, when the cleaning cloth (6) is pulled into the pipe to be cleaned (2), the cleaning cloth (6) is deformed along the inner peripheral shape of the pipe to be cleaned (2). Exactly the same as in Examples 1 and 2, the inner peripheral surface (5) of the pipe to be cleaned (2) can be cleaned.

[0041] The wire (1) inserted from one end (3) of the pipe to be cleaned (2) in order to draw the cleaning cloth (6) into the pipe to be cleaned (2) is one of the wires (la) in the above. However, the other wire (lb) is also possible. Therefore, in this case, if for some reason the cleaning cloth (6) gets stuck or clogged in the pipe to be cleaned (2), one wire (la) By pulling in the pull-back direction, the cleaning cloth (6) can be pulled back to the end (3) side of the pipe to be cleaned (2).

Example 4

[0042] In Examples 1 and 2, the other end (9) of the cleaning cloth (6) is not fixed to the wire (1), and in Example 3 above, the same is applied to both ends of the cleaning cloth (6). The wire rod (1) is fixed, but in Example 4, the pull-back thin wire (15) is fixed to the other end (9) of the cleaning cloth (6) and the pipe to be cleaned ( The cleaning cloth (6) inserted inside from one end (3) of 2) can be pulled back to the end (3) side of the pipe to be cleaned (2). Specifically, as shown in FIG. 6 and FIG. 7, a through hole (16) is formed in the other end (9) of the strip-shaped cleaning cloth (6) covered with the wire (1) at one end (7) as shown in FIGS. Insert a soft elastic pullback wire (15) for pulling back the cleaning cloth (6) into this through hole (16), loop this pullback wire (15) into this bow I return wire The tip of (15) and the main body are fixed using a metal fixing member (17). In addition, the distance between the retracting thin wire (15) and the wire rod (1) of the cleaning cloth (6) is not fixed to the wire rod (1) and the pulling thin wire (15) as shown in FIG.

[0043] By adopting the configuration as described above, compared to Example 3 above, the retracting thin wire (15) is inserted into the cleaning tube (2) from one end (3) into the cleaning cloth (6 ) It is difficult to clean the inner peripheral surface (5) of the pipe (2) to be cleaned with the wire (1) on the other end (9) of the cleaning cloth (6) as in Example 3 above. Since it is not necessary to attach it precisely, it can be manufactured more easily than the third embodiment, and the manufacturing cost can be kept low. If the cleaning cloth (6) is clogged in the cleaning pipe (2) during the cleaning process of the inner peripheral surface (5) of the cleaning pipe (2), pull it back. By drawing the thin wire (15), the cleaning cloth (6) can be pulled back to the one end (3) side of the pipe to be cleaned (2), as in the third embodiment. In addition, the distance between the retracted thin wire (15) and the wire rod (1) of the cleaning cloth (6) is not fixed to the wire rod (1), so the cleaning cloth (6) is placed inside the pipe to be cleaned (2). The cleaning cloth (6) is deformed along the inner peripheral shape of the pipe to be cleaned (2) when pulled in, which is exactly the same as in Examples 1, 2 and 3, and the pipe to be cleaned (2) The inner peripheral surface (5) can be cleaned.

[0044] Also, as shown in FIGS. 6 and 7, the tip of the pullback thin wire (15) inserted through the through hole (16) of the cleaning cloth (6) and the main body portion are made of a metal fixing member ( In order to prevent damage to the inner surface of the pipe to be cleaned (2) by the fixing member (17), the outer periphery of the fixing member (17) is fixed as shown in Figs. 8 and 10. It may be covered with a soft elastic resin cover tube (20).

Example 5

[0045] Further, in Examples 1 to 4 above, the covering fixing portion (8) as shown in Figs. 1 to 6 is fixed to the wire (1), and the covering fixing portion (8) is left exposed. The cleaning cloth (6) is inserted into the pipe to be cleaned (2) from the covering fixing part (8). Even in this state, a sufficient cleaning purpose can be achieved. A protective cap (18) formed of a heat shrinkable material such as polyolefin resin is applied to the outer periphery of the covering fixing part (8) as shown in Figs. 8 and 9.
