filter

This creation is related to the falling head of the drainage system, in particular to a filtering device installed inside the falling head.

The falling head is a necessary structure of the household drainage system, and comprises a body and a drainage cover disposed on the opening of the seat, the drainage cover is provided with a plurality of through-shaped through-holes, and in consideration of drainage smoothness, the foregoing Most of the through holes have a large size design, so that it is impossible to effectively filter out foreign matter. When used for a long time, the water pipe is prone to blockage, or cause a disgusting odor, and even become a place for bacteria and pests to survive. It endangers the health of the user.

Therefore, the user must additionally install a filtering device on the falling head to effectively solve the above problems. However, most of the conventional filtering devices are simple in design, but the filtering effect is not good, and the filtering effect is also enhanced, but the structure is It is too complicated to be disassembled and cleaned, and there is still no solution for the best of both worlds.

The main purpose of the present invention is to provide a filtering device which can be installed on a falling head to filter foreign matter, and has the advantages of simple structure, convenient disassembly and assembly, and excellent filtering effect, and can also balance the smooth drainage.

In order to achieve the foregoing object, a filter device according to the present invention is provided for installation between a body of a water drop head and a drain cover, the filter device comprising: a plate body mounted in the seat body, and An annular convex portion is formed on the surface of the plate body, and the plate body is provided with at least one drainage hole in an inner region of the annular convex portion.

Thereby, when the water flows through the filtering device through the cover of the falling head, it will be blocked by the plate body to slow down the flow rate, and the foreign matter of the hair is blocked by the annular convex portion, and the drainage of the plate body is smoothly performed. The hole is drained, and after a period of use, the user can easily disassemble the filter device for cleaning to maintain home hygiene.

The filter device of the present invention may also have a plurality of slits in the annular convex portion or the plate body located outside the annular convex portion to increase the flow rate and the filtering range.

Preferably, a central portion of the plate body is provided with a perforation, and a peripheral edge of the perforation is formed to protrude from the drainage cover to form a tube portion, so that one end of the tube portion abuts against the drainage cover, which can strengthen the strength of the assembly structure; In addition, a plurality of slits may be provided on the circumferential surface of the pipe body.

In addition, the top edge of the drain cover is higher than the top edge of the seat body, and a gap is formed between the periphery of the drain cover and the seat body, and the drain cover has a ring edge protruding toward the seat body. And the diameter of the annular convex portion is smaller than the diameter of the annular edge, so that the water flow can be smoothly introduced into the slit, and the bottom end of the annular edge of the drainage cover is closer to the plate body than the top edge of the annular convex portion. This causes the water flow to be diverted in the vicinity of the slits, thereby improving the effect of filtering foreign matter.

In order to explain in detail the construction and features of the present invention, the following preferred embodiments are described with reference to the following:

Referring to the first and second figures, the filter device 10 of the embodiment provided by the present invention can be installed between the seat body 2 of a water drop head 1 and the drain cover 3, wherein the seat body 2 is hollow. In the shape of a cylinder, the drain cover 3 has a ring edge 4 and a plurality of through holes 5 and is disposed on the seat body 2. The seat body 2 and the drain cover 3 are assembled by a screw 6 due to the water drop head 1 The specific structure has been known to those skilled in the art and will not be described herein.

It is worth mentioning that the height of the top edge of the drain cover 3 is designed to be higher than the top edge of the base 2, and the diameter of the periphery of the drain cover 3 is smaller than the opening of the base 2 to There is a gap G, so that the water flow will preferentially flow into the gap G, and will flow through the through hole 5 of the drain cover 3 only when the amount of water is large.

The filter device 10 includes a plate body 20 mounted in the base body 2, and an annular convex portion 30 formed by protruding from the surface of the plate body 20 toward the drain cover 2, wherein the plate body 20 is located The inner side of the annular convex portion 30 defines a through hole 21 and a plurality of drainage holes 22. The periphery of the through hole 21 is convex toward the drainage cover 2 to form a tube portion 23, and one end of the tube portion 23 abuts against the drainage. The cover 2 is simultaneously passed through the tube portion 23. Further, the plate body 20 is provided with a plurality of slits 24 in the outer region of the annular convex portion 30.

The annular convex portion 30 is provided with a plurality of slits 31, and the diameter of the annular convex portion 30 is smaller than the diameter of the annular rim 4, and at the same time, the bottom end of the rim 4 of the drain cover 2 is larger than the annular convex portion. The top edge of the 30 is closer to the surface of the plate 20, that is, the annular projection 30 extends into the inner space defined by the rim 4 of the drain cover 2.

After the user turns on the water flow, the water flow will be blocked by the rim 2 of the drain cover 2 and flow into the gap G, so that the water flow will be deflected and decelerated, and guided through the slit 31 of the annular convex portion 30 and the plate body. The slit 24 of 20 causes foreign matter such as hair entrained in the middle of the water flow to be blocked between the plate body 20 and the annular convex portion 30.

When the slits are both blocked by foreign matter, or the flow rate of the water flow is larger, the water flow may directly flow from the through hole 5 into the region of the plate body 20 located inside the annular convex portion 30, at this time, the plate is The drain hole 22 of the body 20 provides a function of filtering foreign matter.

Therefore, the filter structure of the present invention can be applied to various water flows to provide a good filtering effect, and at the same time, the filtered foreign matter is accumulated by the adjacent region of the plate body 20 and the annular convex portion 30 without being easily clogged. occur.

When the user wants to clean, the screw 6 can be easily loosened to disassemble the drain cover 2 and the filter device 10, which is quite convenient to use.

It is worth mentioning that the main feature of the present invention is the structural design between the plate body 20 and the annular convex portion 30. The annular convex portion 30 can decelerate the water flow and cause foreign matter such as hair to be ring-shaped. The convex portion 30 is blocked. Of course, the annular convex portion 30 can be provided with a plurality of slits 31 to enhance the effect of the foreign matter of the original filter. As for the slit 24, the drainage hole 22 and the tube of the plate body 20 in the foregoing embodiment. The structure of the portion 23 can be changed as needed by those skilled in the art, and the structure and arrangement of the drain cover in the foregoing embodiment are for enhancing the auxiliary effect of guiding the water flow.

The present invention provides another embodiment, as shown in FIG. 3, the main structure of which is the same as that of the foregoing embodiment. The difference is that the rim of the drain cover 4 and the peripheral surface of the tubular body 23 are provided with a plurality of slits 41, 231. Can further improve the filtering effect.

It can be seen from the foregoing that the filter device of the present invention not only has a simple structure, but also has an excellent filtering effect, and can take into consideration the drainage performance, and is convenient to use and disassemble, thereby achieving the purpose of the present creation.
