For example, in FIG. 4, two upper and lower collecting bodies 33 and 34 are provided on the shaft 32, so that hair, fiber waste, other dust, and the like are more reliably captured. However, since the collection body 33 has a substantially planar shape, there is a problem that clogging is likely to occur due to the captured hair, fiber waste, and other dust, the flow of drainage is likely to be hindered, and the cleaning frequency increases.

  In addition, since the collectors 33 and 34 are fixed to the shaft 32 and have a complicated structure, the hair collected from the hair catcher, fiber waste, other waste, etc. when cleaning the drain plug There is a problem that it is difficult to remove.

  In the hair catchers shown in Patent Documents 1 to 3, as described above, the collection body is basically formed in a lattice shape, and the collection effect of hair, fiber waste, other waste, etc. is not always sufficient, It is not always easy to clean trash entangled in the lattice portion.

  The hair catcher shown in Patent Document 4 is easy to remove and clean a certain length of hair, fiber waste, and other dust, but further improvement is required in terms of collecting slightly fine dust and the like.

  The present invention aims to solve the above-described problems of the conventional hair catcher, prevents clogging, improves the flow of drainage, suppresses increase in the frequency of cleaning, and further, for drain plugs. The hair catcher having a structure that can easily remove hair, fiber waste, and other dust collected by the hair catcher of the present invention.

  In order to solve the above problems, the present invention is a hair catcher in which a collector is attached to a shaft portion, and the collector is formed in a direction parallel to the direction of the shaft portion and a cylindrical portion parallel to the direction of the shaft portion. A drain slit is formed in the cylindrical portion, a non-perforated flat portion is formed in the flange portion within a predetermined range, and a drain hole is formed on the outer peripheral side of the flat portion. A hair catcher is provided.

  The drainage slit of the cylindrical part is preferably formed in an elongated shape in the same direction as the direction of the shaft part.

  The drain hole portion of the flange portion is preferably formed in a cutout shape at the outer peripheral end portion.

  It is preferable that a rising portion is formed at the outer peripheral end of the flange portion.

  It is preferable that a lattice-like lower collector is provided below the collector.

  The lower collecting body preferably has a downwardly convex curved shape.

  The hair catcher according to the present invention collects hair, fiber debris, other debris, etc. in both the drain slit and drain hole provided in the cylindrical portion and flange portion, and allows the waste water to pass through. The collection effect and drainage effect are increased.

  The dust collected in the drain slit falls, and the dust collected in the drain hole accumulates in the flange portion. Therefore, the discharge hole is not easily blocked, and the drainage easily flows smoothly. As a result, it is possible to suppress an increase in the frequency of cleaning the collector, and it is easy to remove dust and the like when the hair catcher is removed from the drain outlet together with the drain plug.

And a flange portion 13 formed integrally with each other. In other words, the flange portion 13 is formed so as to continuously spread from the lower end of the cylindrical portion 2 in a direction perpendicular to the axis of the cylindrical portion 12 (the radial direction of the cylindrical portion 12).

  With the cylindrical portion 12 concentrically attached to the shaft portion 3, as shown in FIG. 3, a gap 14 is formed between the cylindrical portion 12 and the shaft portion 3 so that drainage flows down. The inner diameter is formed larger than the outer diameter of the shaft portion 3.

  As shown in FIGS. 1 and 2B, a plurality of drainage slits 16 are formed in the circumferential wall 15 of the cylindrical portion 12 at intervals in the circumferential direction. The drain slit 16 of the cylindrical portion 12 is formed in an elongated shape in the same direction as the direction of the shaft portion 3. In this embodiment, the drain slit 16 is formed in the cylindrical portion 12 in two upper and lower stages, but may be one stage.

  As shown in FIGS. 2A and 2B, a cylindrical guide 18 formed concentrically and parallel to the shaft portion 3 is formed in the upper end opening 17 of the cylindrical portion 12. The inner diameter of the cylindrical guide 18 is such that the cylindrical portion 12 can move when an axial force is applied to the shaft portion 3, but the shaft portion 3 is not displaced from the shaft portion 3 to the shaft portion 3 during use. It is formed slightly larger than the shaft portion 3 so that it can be closely fitted.

  The flange portion 13 has a circular non-perforated flat surface portion 19 formed in a predetermined range in plan view, and a drain hole portion 20 formed on the outer peripheral side of the flat surface portion 19. A plurality of the drain holes 20 are formed in a cutout shape at intervals in the circumferential direction at the outer peripheral end 21.

  In the present embodiment, as shown in FIGS. 2A to 2C, a rising portion 22 is formed at the outer peripheral end portion 21 of the flange portion 13. The rising portion 22 is formed in an annular shape with a constant width in the radial direction in plan view, and is inclined upward from the flat portion 19 toward the outer periphery.

  The plurality of drain hole portions 20 are formed in the rising portion 22 at intervals in the circumferential direction. Since the flange portion 13 has such a configuration, as shown in FIG. 2C, dust and the like 29 that cannot be passed through the drain slit 16 and the drain hole portion 20 are collected. Can fall and accumulate.

  When the cylindrical portion 12 is attached to the shaft portion 3, the retainer 6 is removed from the shaft portion 3, the cylindrical guide 18 is fitted to the shaft portion 3 from below, and the cylindrical portion 12 is drained along the shaft portion 3. The cylindrical portion 12 is attached to the shaft portion 3 in close contact with the shaft portion 3 by moving to the appropriate position in the direction of the stopper 2. The drain plug 2 may be removed from the shaft portion 3 and the cylindrical portion 12 may be fitted and attached from above.

  1 and 3, the capturing body 4 is held in a horizontal state so as to be orthogonal to the shaft portion 3. The overall shape of the capturing body 4 is a concave curve. Specifically, a hub 23 that is fitted to and attached to the shaft portion 3 in a close contact state, and a lattice portion 24 that integrally forms around the hub 23 around the hub 23 and captures dust and the like. It consists of.

  The lattice unit 24 includes an intermediate annular frame 25 and an outer annular frame 26 that are provided concentrically and stepwise above the hub 23, and the intermediate annular ring is provided between the hub 23 and the intermediate annular ring 25. Radial members 27 provided respectively in the radial direction between the frame 25 and the outer annular frame 26 are spaced apart at appropriate intervals in the circumferential direction and are integrally formed.

The capturing body 4 has a function of capturing dust or the like that has flowed downward without being captured by the capturing body 5, for example, a contact lens.

(Function)
The operation of the hair catcher 1 of the embodiment of the present invention having the above configuration will be described. The hair catcher 1 is assembled as shown in FIG. 1 into the shaft portion 3 provided with the drain plug 2 at the upper end, and in this state, the hair catcher 1 is inserted into the discharge hole 8 from the drain port 9 such as a wash bowl and is shown by the imaginary line in FIG. As described above, the stopper 6 is installed so as to abut on the push-up arm 11.

  The push-up arm 11 is moved up and down by the operation link 10, and as shown by an imaginary line in FIG. 3, when it is below, the drain plug 2 closes the drain port 9 (see the imaginary line in FIG. 3). When the push-up arm 11 moves upward by the operation link 10, the drain plug 2 is lifted through the shaft portion 3, and the drain port 9 is opened (see the solid line in FIG. 3).

  A part of the waste water flowing from the drain port 9 through the discharge hole 8 passes through the drain slit 16 of the cylindrical part 12 in the collector 5 and flows down into the gap 14, and the other part of the drainage hole part 20. Pass through. In this way, the waste water that has flowed down in the gap 14 and has passed through the drain hole portion 20 further passes through the trap 4 and is discharged from the discharge hole 8 to the drain passage 28.

  When the drainage passes through the drainage slit 16, hair, fiber waste, other dust, and the like are collected in the drainage slit 16. Further, when the drainage passes through the drainage hole 20, hair, fiber waste, other garbage, etc. are collected in the drainage hole 20. As shown in FIG. 2C, the dust 29 collected in the drain slit 16 and the drain hole 20 in this way accumulates in the flange portion 13.

  Then, dust, contact lenses, and the like that have passed through the collection body 5 are captured by the lattice portion 24 of the capture body 4 provided below the collection body 5.

  Thus, since the hair catcher 1 of this invention collects hair, fiber waste, other garbage, etc. in both the drain slit 16 and the drain hole part 20, and lets waste water pass through, the collection effect of garbage etc. And drainage effect is excellent.

  In addition, there is less entanglement of dust and clogging is less likely to occur as compared with a collector having a mesh or lattice. The dust collected in the drain slit 16 falls, and the dust collected in the drain hole 20 falls along the inclined surface of the rising portion 22 and accumulates in the flange portion 13. Therefore, the discharge hole 8 is not easily blocked, and the drainage easily flows smoothly.

  As a result, it is possible to suppress an increase in the frequency of cleaning of the collector 5, and it is easy to remove dust and the like when the hair catcher 1 is removed from the discharge hole 8 together with the drain plug 2.

  As mentioned above, although the best form for implementing the hair catcher which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, It was described in the claim It goes without saying that there are various embodiments within the scope of technical matters.

  Since the hair catcher according to the present invention is configured as described above, it can also be applied to discharge holes such as a wash bowl, a bathtub, and a bathroom washing place.
