Further, the water retaining eaves further comprise a second water retaining eaves 22 which is arranged in the overflow hole 23 and is close to one end of the cover body, the second water retaining eaves 22 are provided with second water retaining surfaces 222, a height difference exists between the second water retaining surfaces 222 and the liquid level 3 of the base cavity 21, and a height difference exists between the first water retaining surfaces 121 and the second water retaining surfaces 222, so that the first water retaining eaves 12 and the second water retaining eaves 22 are matched together to play a role in better preventing splashed water drops 5 from splashing.

In addition, the second water blocking eave 22 is provided with a backflow surface 221, the backflow surface 221 is obliquely arranged towards the overflow port 15, the backflow surface 221 is located on the opposite side of the second water blocking surface 222, and when the splashed water splashes onto the backflow surface 221 of the second water blocking eave 22, the water can flow back to the base cavity 21, so that the water drops 5 are further effectively prevented from splashing from the overflow port 23.

Preferably, referring to fig. 5, the included angle C between the reflow surface 221 and the Y direction of the base 2 is set to be 60-85 degrees, and it should be noted that the included angle C may be set to any value of 60-85 degrees, for example, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees or 85 degrees, and preferably set to be 70 degrees according to practical needs.

Further, the height difference between the first water blocking surface 121 and the second water blocking surface 222 is set to 3 to 15mm, specifically, the height difference between the second water blocking surface 222 and the liquid surface 3 is Y1, the height difference between the first water blocking surface 121 and the liquid surface 3 is Y2, the height difference between Y2 and Y1 is 3 to 15mm, of course, the height difference between Y2 and Y1 may be set to any value of 3 to 15mm, for example, 3mm, 4.5mm, 6mm, 7.5mm, 9mm, 10.5mm, 12mm, 13.5mm or 15mm, and preferably 9mm, according to actual needs.

Specifically, when the overflow cover 1 is covered at the overflow hole 23, the first water-retaining eave 12 is located above the second water-retaining eave 22, and the length X2 of the first water-retaining eave 12 in the X direction is greater than the length X1 of the second water-retaining eave 22, and X2 is at least 3mm greater than X1, and when the overflow cover 1 is covered on the overflow hole 23, the first water-retaining eave 12 and the second water-retaining eave 22 have an overlapping dimension X3 in the base 2X direction. In this way, the water droplets 5 are smoothly and specifically blocked to prevent the water droplets 5 from splashing.

Preferably, the cover comprises a cover plate 11, an extension wall 13 connected to the cover plate 11, and a mounting plate 14 connected to the extension wall 13; the mounting plate 14 is provided with a mounting part 141, a connecting part 231 which is butted with the mounting part 141 to be fixed is arranged at the overflow hole 23, the extending wall 13 and the cover plate 11 jointly enclose into an overflow cavity, the connecting part of the extending wall 13 and the cover plate 11 is adjacent to the liquid level 3 of the base cavity 21 to form an overflow port 15, and the first water retaining eave 12 is connected to the inner surface of the cover plate 11. Specifically, the first water blocking eave 12 is vertically connected to the inner surface of the cover plate 11. Further, the length X2 of the first water blocking eave 12X is larger than the width X4 of the overflow port 15, and it is understood that the width X4 of the overflow port 15 may also be expressed as the distance between the cover and the base 2. Specifically, X2 is at least 5mm larger than X4, the distance X5 between the inner surface of the cover and the second water blocking eave 22X direction is set to-1 to 3mm, the difference between X5 and X4 may be set to any value of-1 to 3mm according to actual needs, for example, -1mm, 0mm, 1mm, 2mm or 3mm, and preferably, 1mm.

Preferably, the cover plate 11, the extension wall 13 and the mounting plate 14 are integrally formed, and through the design of integral forming, the overall strength on the overflow cover 1 is high, the stability is good, and the loosening and falling-off conditions generated in the using process are prevented. In a refinement, the extension wall 13 and the cover plate 11 jointly enclose a flared overflow chamber. It will be appreciated that the extension wall 13 and the inward inclination are formed on the cover plate 11. Therefore, water can conveniently flow out of the overflow channel 4, and meanwhile, pollutants such as rice grains and the like can be buffered, so that the pollutants are prevented from entering the overflow channel 4.

In addition, a filter screen can be arranged in the cover body, so that the pollutants are further prevented from overflowing out of the overflow holes 23 directly through the overflow channel 4, and the overflow channel 4 is prevented from being blocked. Preferably, the filter screen is detachably connected with the cover body, so that the filter screen is convenient to clean.
