As an improvement of the cleanable floor drain of the present invention, the surface cover, the inner core and the outer core are all made of corrosion-resistant metal materials.

Compared with the prior art, the beneficial technical effect of the present invention is:

The invention adopts the inner core as the filter layer to separate sundries and sewage to prevent the sewer pipe from being clogged; the outer core is used as the water storage layer so that the sieve hole of the inner core is below the liquid surface, and the sewage is under the action of water pressure during sewage discharge , flows out from the sieve hole of the inner core to the outer core, flows around the inner core to the other side, and then flows upward, and is discharged into the sewer pipe from the drain outlet of the outer core above the sieve hole. The water storage layer can prevent the foul smell from overflowing in the sewer pipe, and can also prevent the sewage from overflowing. Since the sewage flows forward, there is no long-term stagnant water. There is a buckle on the cover, which is locked with the buckle slot in the fixing device by rotation to prevent the cover from being lost.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Figures 1-3 comprehensively, a cleanable floor drain includes an inner core 1 , an outer core 2 and a cover 3 . The inner core 1 is sleeved in the outer core 2, and the outer core 2 protrudes into the entrance of the sewer pipe, and the cover 3 is covered on the upper opening of the outer core 2, which is flush with the ground, and the cover 3 is provided with a water inlet. The water inlet communicates with the upper opening of the inner core 1, the side wall of the inner core 1 is provided with a screen hole 4, the inner core 1 communicates with the outer core 2 through the screen hole 4, and the side wall of the outer core 2 away from the screen hole 4 is provided with There is a drain 7 through which the outer core 2 communicates with the sewer pipe, and the horizontal position of the drain 7 is higher than that of the sieve hole 4 .

As an embodiment of the present invention, the bottoms of the inner core 1 and the outer core 2 are provided with a lower cover, the lower cover of the inner core 1 is directly abutted against the upper surface of the lower cover of the outer core 2, and the screen hole 4 is located in the inner The lower part of core 1. The purpose of this design is to make the sieve holes 4 as close as possible to the bottom of the outer core 2. When the sewage is discharged, the water pressure pushes the sewage to flow forward without stagnant water inside the inner core 1 and the outer core 2. When the sieve holes of the inner core 1 are blocked due to too much debris, the inner core 1 can be directly taken out, cleaned and put back again.

As an embodiment of the present invention, the upper opening of the outer core 2 and/or the inner core 1 is an inverted tapered opening, which can effectively drain water, reduce the materials for manufacturing the outer core 2 and/or the inner core 1 and facilitate installation.

As an embodiment of the present invention, the upper edge of the inner core 1 forms an extension section outward, and the extension section is placed at the lower opening platform of the inverted conical opening of the outer core 2, thereby just fixing the position of the inner core 1, and also facilitating the inner core. 1 free take out. The extension section is provided with a symmetrically arranged fixing device 6, the fixing device 6 is provided with a buckle groove, and the lower surface of the cover 3 is provided with a symmetrically arranged buckle 5; by rotating the cover 3, the buckle 5 is rotated and inserted In the buckle groove, the face cover 3 is fixedly connected with the inner core 1 .

As an embodiment of the present invention, the surface cover 3, the inner core 1 and the outer core 2 are all made of corrosion-resistant metal materials. The present invention can still select other corrosion-resistant plastic polymer materials.

Specifically referring to FIG. 1 , the sewage flow direction of a cleanable floor drain according to an embodiment of the present invention is: a→b→c→d→e→f. The specific process is: the sewage flows into the inner core 1 from the inverted tapered opening of the inner core 1, and the sewage from the top to the bottom inside the inner core 1 flows out from the screen hole 4 on the bottom side of the inner core 1 to the outer core 2 through extrusion. Inside, the sewage flowing out of the outer core 2 flows around the inner core 1 to the other side. When more and more sewage is discharged from the interior of the outer core 2, the sewage flows upward. When the height of the sewage rises to the height of the drain 7, the sewage Flow into the sewer pipe from the drain port 7.

Specifically referring to FIG. 2 , when a cleanable floor drain according to an embodiment of the present invention stops draining water, accumulated water is stored inside the outer core 2 below the position of the drain outlet 7 , and the liquid level of the accumulated water covers the sieve holes on the inner core 1 4. In this way, the odor or bedbugs in the sewer cannot escape from the floor drain.

Specifically referring to FIG. 3 , a propeller blade structure is formed on the surface cover 3 , the water inlet is a gap formed between the propeller blades, and the opening of the gap is horizontally oriented. Sewage flows into the gap along the surface of the propeller blade, and the upper surface of the propeller blade is provided with lines, so that other sundries and foreign objects are not easy to enter the gap.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of changes or modifications within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
