Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drain outlet filter that is placed on a drain outlet lid in order to prevent dirt such as hair from entering the drain outlet and clogging in a bathroom, a wash basin, or other areas around the water.
[0002]
[Prior art]
Conventionally, as this type of drainage filter, a polypropylene or vinyl chloride filter provided with a dust collecting part has been used.
[0003]
[Problems to be solved by the invention]
However, this has the following disadvantages.
[0004]
First of all, polypropylene drainage filters can be lifted by water flow simply by being placed on the drainage, so it is inconvenient that the claw formed on the drainage filter must be attached to the lid of the drainage outlet when in use. In addition, depending on the shape of the lid of the drain outlet, there is a possibility that the claw does not engage well.
[0005]
On the other hand, since the drain filter made of vinyl chloride is soft, it is necessary to pick up the garbage directly or using a tissue paper when removing the entanglement in the dust collecting part, which is unsanitary for viewing.
[0006]
In view of such circumstances, the present invention provides a drainage filter that can be easily placed and used regardless of the shape of the lid of the drainage port and can remove dust in a sanitary manner. With the goal.
[0007]
[Means for Solving the Problems]
First, the invention according to claim 1 of the present invention is such that the concave substrate (9) rises from the inner peripheral edge of the annular support plate (2) via the rising wall (6), and the peripheral edge is a node. It has a main body (4) connected in a freely oscillating manner, an upper dust collector (10) is formed on the substrate, and a weight (11) is attached to the substrate.
[0008]
By adopting such a configuration, the main body is stabilized by the weight, so that the drainage filter is not likely to float up due to water flow during use, but it also removes the trash trapped by the upper dust collector In such a case, the substrate vibrates so that the substrate changes from a concave spherical shape to a convex spherical shape by simply hitting the main body against the edge of the trash can and the like, and the dust drops off.
[0009]
In the invention according to claim 2 of the present invention, the upper dust collector (10) is a lattice-shaped object in which a plurality of horizontal eyes (10b) are overlapped with a plurality of vertical eyes (10a). Adopted and configured. With this configuration, the contact area between the upper dust collector and the dust is reduced, and the dust can be easily dropped due to the vibration of the substrate.
[0010]
The invention according to claim 3 of the present invention is configured such that the weight (11) is detachable from the substrate (9). With this configuration, the weight can be separated from the main body and discarded, and acts to be friendly to the global environment.
[0011]
Furthermore, the invention according to claim 4 of the present invention is configured by adopting polypropylene as the material of the main body (4). With this configuration, the chemical resistance of the main body is improved and acts so as not to easily deteriorate.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing a first embodiment of a drain filter according to the present invention, wherein (a) is a plan view thereof, (b) is a front view thereof, and (c) is a CC line of (a). It is sectional drawing by a line.
[0014]
As shown in FIG. 1, the drain filter 1 includes a polypropylene main body 4, a metal weight 11 such as soft metal, and a polypropylene lid body 12. The main body 4 includes a support plate 2 and a lower part. It consists of a dust collector 3, a handle 5, a rising wall 6, a water passage hole 7, a substrate 9, an upper dust collector 10 and a weight storage box 13.
[0015]
That is, as shown in FIG. 1, the main body 4 has an annular support plate 2, and three lower dust collectors 3 are formed on the support plate 2. Furthermore, a handle 5 is erected upward at a part of the outer peripheral edge of the support plate 2. Further, a frustoconical rising wall 6 is connected to the inner peripheral edge of the support plate 2 obliquely upward along the entire circumference, and a plurality of water passage holes 7 are formed in the rising wall 6. Further, a concave spherical substrate 9 is connected to the upper end of the rising wall 6 so as to freely vibrate with its peripheral edge as a node, and an upper dust collecting body 10 is formed on the entire surface of the substrate 9. Further, a weight storage box 13 is formed at the center of the substrate 9. As shown in FIGS. 1A and 1C, each lower dust collector 3 has a lattice shape in which a plurality of horizontal eyes 3b overlap each other above a plurality of vertical eyes 3a. Similarly, the upper dust collecting body 10 has a lattice shape in which a plurality of horizontal eyes 10b overlap each other above the plurality of vertical eyes 10a.
[0016]
As shown in FIG. 1 (c), the weight 11 is detachably stored in the weight storage box 13 of the main body 4, and the lid body 12 is placed with the weight 11 stored in the weight storage box 13. The weight 11 can be fixed to the main body 4 by being crowned.
[0017]
Since the drain filter 1 has the above-described configuration, when the drain filter 1 is used, the drain filter 1 is connected to a drain (not shown) while the weight 11 is stored in the weight storage box 13. ). Then, since garbage, such as hair, is entangled and collected in the lower garbage collector 3 and the upper garbage collector 10, it does not enter the drain and become clogged. At this time, since the weight 11 is built in the drain filter 1, it is difficult for the drain filter 1 to be lifted by the water flow during use. Further, since the concave spherical substrate 9 is continuously provided so as to rise through the rising wall 6, the weight storage box 13 remains on the drain outlet lid even if the drain filter 1 is placed on the drain lid. The drain filter 1 can be placed without any trouble without contact.
[0018]
And in order to remove the dust collected by the drain filter 1 in this way, the handle 5 is grasped and the main body 4 is hit against the edge of a trash box (not shown). Then, the shock causes the substrate 9 of the drain filter 1 to vibrate so as to change from a concave spherical shape to a convex spherical shape, so that the trash entangled with the lower dust collecting body 3 and the upper dust collecting body 10 is dropped and the trash can is dropped. to go into. At this time, as described above, the lower dust collector 3 and the upper dust collector 10 have a lattice shape in which a plurality of horizontal eyes 3b and 10b overlap each other on the upper side of the plurality of vertical eyes 3a and 10a. Since the area is small, dust can be easily removed by vibration.
[0019]
Moreover, since the main body 4 and the lid body 12 of the drain filter 1 are made of polypropylene, they are superior in chemical resistance and hard to deteriorate compared to those made of vinyl chloride. Moreover, since the weight 11 is detachable with respect to the main body 4, when the drain filter 1 is discarded, the metal weight 11 can be separated from the polypropylene main body 4 and the lid body 12 and discarded. Also friendly to the global environment.
[0020]
In the above-described embodiment, the drain filter 1 in which the three lower dust collectors 3 are formed on the support plate 2 has been described. However, the number of the lower dust collectors 3 is not limited to three, It is also possible to omit the lower dust collector 3.
[0021]
【The invention's effect】
As described above, according to the invention according to claim 1 of the present invention, since the main body is stabilized by the weight, it is difficult for the drainage filter to be lifted by the water flow during use, and the upper dust trapping is not caused. In order to remove the trash collected by the collection, simply hit the main body against the edge of the trash can and the substrate will vibrate so that it changes from a concave spherical shape to a convex spherical shape. It is possible to provide a drainage filter that can be easily placed and used regardless of the shape of the lid of the mouth and can remove dust in a sanitary manner.
[0022]
Further, according to the invention according to claim 2 of the present invention, the contact area between the upper dust collector and the dust is reduced, and it becomes easy for the dust to fall off due to the vibration of the substrate, so the usability of the drain filter is improved. To do.
[0023]
In addition, according to the invention according to claim 3 of the present invention, the weight can be separated from the main body and discarded, and it becomes easy to recycle the drain filter because it becomes easy to the global environment.
[0024]
Furthermore, according to the invention which concerns on Claim 4 among this invention, since the chemical resistance of a main body improves and it becomes difficult to deteriorate, the long-term durability of a drain filter improves.
