The structure and function of the present invention will now be described in detail by way of the following embodiments in conjunction with the accompanying drawings. As shown in FIG. 1 to FIG. 3, a filtering device 30 provided in a preferred embodiment of the present invention is disposed between a drain cover 10 and a body 20, and the diameter of the drain cover 10 is slightly smaller than that of the base 20. Opening, so when the drain cover 10 is embedded in the seat body 20, a first water inlet passage 1 1 is formed on the outer edge of the drain cover 10, and the top edge of the drain cover 10 is higher than the top edge of the seat body 20, and A perforation is formed in the center of the top surface as a second water inlet passage 12. The filter device 30 of the present invention comprises a positioning plate 40, a first filter unit 50, a slow flow seat 60 and a second filter unit 70, wherein the positioning plate 40 and the slow flow seat 60 together form a slow flow unit. The specific structures of the various components of the present invention are detailed as follows:

The positioning plate 40 is mounted in the base body 20, and has an opening 41 having an area larger than the cross-sectional area of the second water inlet passage 12. The top surface of the positioning plate 40 is convexly provided with a plurality of convex portions 42 which can be staggered. In the embodiment, each convex portion 42 is arranged in a spiral shape to guide the flow of water. Of course, those skilled in the art may change the convex portion 42 into a single annular convex portion or other staggered arrangement depending on the situation. In addition, the drain cover 10 has a flange 13 protruding toward the positioning plate 40, and at least one first joint portion 14 is formed at a suitable position of the flange 13. The top surface of the positioning plate 40 is correspondingly provided with at least one second joint. The portion 43 is fixed to the first joint portion 14 so that the drain cover 10 and the positioning plate 40 can be firmly coupled. The first bonding portion 14 and the second bonding portion 43 are respectively complementary bumps and grooves in the embodiment, and are arranged in three equal intervals. Column.

The first filter unit 50 is composed of a plurality of slits, and is formed in the flange 13 of the drain cover 10 and the convex portion 42 of the positioning plate 40, and thus is located between the first water inlet channel 1 1 and the opening 41 of the positioning plate 40. The foreign matter in the water flow from the first water inlet passage 11 can be filtered.

The slow flow seat 60 is composed of an annular wall 60A and a bottom plate 60B, and the top edge of the annular wall 60A extends upward to form a plurality of connecting portions 61 for connecting the periphery of the opening 41 of the positioning plate 40, so that the slow flow seat 60 is located below the second water inlet passage 12 and the opening 41, and the connecting portion 61 is spaced apart, and at least one drainage channel 62 is formed between the adjacent two connecting portions 61, so that the slow flow seat 60 can slow down from the second water inlet The vertical water flow velocity of the passage is then discharged by the drain passage 62. In addition, the bottom wall of the wall 60A of the slow flow seat 60 is provided with a water outlet hole 63 for removing moisture remaining in the slow flow seat 60, and the bottom plate 60B of the slow flow seat 60 extends outward and is bent upward to form a ring groove 64. By shielding the water outlet 63, a water seal can be formed moderately at the bottom of the slow flow seat 60. It is worth mentioning that the structure of the above-mentioned slow flow seat is an exemplification of the embodiment, and the slow flow seat can be changed into an arc plate with an open upward direction, and the positioning plate is also connected by a plurality of connecting portions, which can also achieve the effect of buffering the vertical water flow rate. And the aforementioned curved plate can also be provided with a water outlet hole. In addition, the position of the slow flow seat can also be adjusted upward from the lower side of the positioning plate, and the slow flow seat can be raised to make the bottom plate flush with the positioning plate.

In this embodiment, the second filter unit 70 is a mesh structure composed of metal strips arranged to be able to pass downward from the top surface of the drain cover 10, and the top edge thereof can abut against the top surface of the drain cover 10 to make the second filter. The unit 70 is disposed between the second water inlet passage 12 and the slow flow seat 60, and the bottom end of the second filter unit 70 extends downward to the inside of the slow flow seat 60, and is capable of filtering foreign matter in the water flow from the second water inlet passage 12. . Of course, those skilled in the art can change the mesh structure in this embodiment to a spiral structure like a spring element or other structure having a filtering effect as needed.

With the foregoing structure, in the case of a low water flow rate, the water flow will mainly flow through the first water inlet passage 1 through the first filter unit 50 while being affected by the flange 13 and the convex portion 42 to lower the level of the water flow. The flow rate can thus increase the filtering effect of the first filter unit 50.

In the case of high water flow, the water flow will inevitably flow into the second water inlet passage 12 and pass through the second filter unit 70 in addition to flowing through the first water inlet passage 11 while being reduced by the influence of the slow flow seat 60. The vertical flow rate of the water stream, in turn, increases the filtering effect of the second filter unit 50.

According to the applicant's experimental results, the shorter hair will sink into the water stream and mainly flow through the first water inlet channel 1 1. The longer hair tends to float on the water surface and mainly flows through the second water inlet channel 12 Since the present invention simultaneously provides the first and second filtering units for the foregoing two situations, And there is a horizontal and vertical slow-flow structure, so it can improve the filtration effect to nearly 100%.

In addition to the foregoing embodiments, the slow flow seat of the present invention can also be changed to a structural design that can be moved relative to the positioning plate, that is, an elastic element, such as a tension spring, can be used to bring the slow flow seat away from or away from the positioning plate. , in turn, can open or close the drainage channel. In this way, the present invention can also utilize the closed state of the drainage channel, that is, the slow flow seat abuts against the positioning plate, thereby achieving the effect of preventing pests or odors from entering the room. The elastic member may be connected between the slow-moving seat and the positioning plate, or the elastic member may be connected to the slow-moving seat only at one end thereof, and the other end is connected to the seat through the opening of the positioning plate. Or the proper location of the drain cover.

Finally, it should be noted that the constituent elements disclosed in the foregoing embodiments of the present invention are merely illustrative and are not intended to limit the scope of patent protection of the present invention. Other alternatives or variations of equivalent elements should also be patented in this case. Covered by the scope of protection.
