Description

Filter plate

The present invention relates to a filter disc, and more particularly to a filter disc suitable for a water drop head disposed on the floor of a bathroom or a toilet.

Referring to Figures 1 to 3, a conventional filter disc 1 is adapted to be placed on a water drop head 14 comprising a base 141, a drain cover 142 mounted to the base 141, and a plurality of The drain hole 143 of the drain cover 142. The conventional filter disc 1 includes a disc body 11 located above the water drop head 14 and covering the drain holes 143, a plurality of filter holes 12 formed in the disc body 11, and three bottom surfaces of the disc body 11 downward. The bottom post 13 projects into the drain holes 143.

When water on the ground of one of the bathroom or the toilet flows to the vicinity of the conventional filter disc 1 and the water drop head 14, the water flows downward from the upper portion of the disc body 11 through the filter holes 12 into the drain holes 143. Then, it is discharged downward through the drain holes 143.

However, the conventional filter disc 1 has a disadvantage in that the filter holes 12 can only allow the water to pass straight downward. Since the disc body 11 itself has a thickness, the top surface of the water drop head 14 is protruded, and the disc body 11 is The circumference of the circumference is closed, so when the amount of water is small, the height of the water is insufficient to flood the thickness of the tray body 11 and rise to the top surface of the tray body 11, at which time it is easy to be deposited on the tray body 11. The peripheral edge cannot flow to the filter holes 12, so that the water cannot be discharged, resulting in poor drainage.

Accordingly, it is an object of the present invention to provide a filter disc that is at least capable of overcoming the disadvantages of the prior art.

Thus, the novel filter disc is adapted to be placed on a water drop head, the water drop head comprising a drain cover, and a plurality of drain holes formed in the drain cover for water to pass therethrough. The filter disc includes a disc body located above the water drop head and covering the drain holes, and a plurality of straight filter holes formed directly on the disc body and extending from the top surface of the disc body to the bottom surface, and A lateral filter hole is formed transversely to the disk body and communicates inwardly from the outer side of the disk body to the bottom surface of the disk body. The straight filter holes allow the water to pass through the disk body from top to bottom and flow into the drain holes, and the side filter holes allow the water to pass through the disk body from the outside and into the drain holes. .

The effect of the novel is that the side filter holes allow the water to circulate laterally and flow into the drain holes, thereby avoiding the problem of siltation generated when the amount of water is small.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 4-6, a first embodiment of the novel filter disc 2 is adapted to be placed over a water drop head 7. The water drop head 7 is mounted on a floor of a bathroom or a toilet and includes a base 71 that is hollow and communicates with a drain pipe (not shown), a drain cover 72 mounted on the base 71, and a plurality of forms. The drain cover 72 is provided with a drain hole 73 through which water can flow.

The filter disc 2 comprises a disc body 3 having a rectangular shape and located above the water drop head 7, the disc body 3 including a base wall 31 for covering the drain holes 73, and a peripheral wall downwardly from the base wall 31. Extending and the bottom end abuts against the surrounding wall 32 of the drain cover 72. The base wall 31 has six ribs 311 which are criss-crossed and extend downward from the bottom surface of the base wall 31. Both ends of each rib 311 are connected to the surrounding wall 32, and the bottom surface of each rib 311 and the surrounding wall 32 The bottom surface is flush. The ribs 311 can be used to enhance the mechanical strength of the base wall 31. The width of the side of the surrounding wall 32 away from the base wall 31 is greater than the width of the side adjacent to the base wall 31, and the outer side surface of the surrounding wall 32 has a curved surface adjacent to the base wall 31. One side is gradually curved outwardly away from one side of the base wall 31, so that the water flows more easily to the periphery of the surrounding wall 32 and flows to the top surface of the base wall 31. It should be noted that in other variations of the first embodiment, the number of the ribs 311 may be increased or decreased, and the bottom surface of the ribs 311 may not be flush with the bottom surface of the surrounding wall 32, or may be omitted. It is higher than the bottom surface of the surrounding wall 32, and the outer side surface of the surrounding wall 32 may also be a sloped surface.

The filter disc 2 further includes a plurality of straight filter holes 4 formed directly on the base wall 31 and extending from the top surface to the bottom surface, and a plurality of laterally formed holes 32 formed on the surrounding wall 32 and facing inwardly from the outside and communicating downwardly from the bottom surface. The side filter hole 5 and a plurality of bottom posts 6 projecting downward from the bottom surface of the base wall 31 into the drain holes 73. The straight filter holes 4 are not shielded by the ribs 311 and communicate with the drain holes 73, and the water is allowed to flow from the top to the bottom through the base wall 31 and downward to the drain holes 73. The side filter holes 5 are not shielded by the ribs 311 and communicate with the drain holes 73, and the water can be discharged from the outside through the surrounding wall 32 and downwardly to the drain holes 73. The widths of the straight filter holes 4 and the side filter holes 5 are smaller than the drain holes 73. In the first embodiment, the widths of the straight filter holes 4 and the side filter holes 5 are 1.5 mm. It can be used not only to filter foreign matter in the water, such as hair, debris, toilet paper, etc., but also to prevent cockroaches or mosquitoes from entering the bathroom or toilet from bottom to top. The bottom posts 6 are snapped against the drain holes 73, and the base wall 31 can be positioned above the drain cover 72 without slipping.

When the water on the floor of the bathroom or toilet flows to the vicinity of the filter disc 2 and the water drop head 7 and the amount of water is small, the water located at the periphery of the surrounding wall 32 is inwardly and downwardly from the side filter holes 5. It flows into the drain holes 73, so that no siltation occurs. When the amount of water increases and the water level rises above the thickness of the surrounding wall 32, the water flows over the top surface of the disk body 3 and flows downwardly from the straight filtering holes 4 into the drainage holes 73. At this time, the straight filter holes 4 and the side filter holes 5 can simultaneously pass the water, and the drainage efficiency can be improved.

Referring to FIG. 7, a second embodiment of the filter disc 2 of the present invention has a configuration substantially the same as that of the first embodiment, the difference being that the outer shape of the filter disc 2 is different, and the filter disc 2 of the second embodiment is The base wall 31 of the filter disc 2 has three ribs 311, one of the ribs 311 is annular and the center of the ring is located at the center of the surrounding wall 32, and the other two ribs 311 are perpendicular to each other and the intersection is located at The center of the surrounding wall 32, and the ends of the ribs 311 perpendicularly intersecting each other are connected to the surrounding wall 32. Of course, in other variations of the second embodiment, the number of the ribs 311 can also be increased or decreased, and the shape can also be changed.

As can be seen from the above, the filter disc 2 of the present invention allows the water to enter and discharge downwardly by increasing the drainage design of the side filter holes 5, thereby preventing the water from accumulating on the periphery of the disc body 3 when the amount of water is small. It can improve the efficiency of drainage and make it more convenient to use, so it can achieve the purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
