The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

referring to fig. 1 to 3, the present embodiment discloses a toilet with a flushing function, which comprises a liner tip 1 and a sewage drain which are mutually communicated, wherein an annular gentle slope 11 and an annular drop slope 12 for forming a drop are circumferentially arranged on the inner wall of the liner tip 1 from top to bottom, the annular drop slope 12 is inclined backwards from top to bottom, a flat gentle slope 13 is connected below the annular drop slope 12, the annular gentle slope 11 and the flat gentle slope 13 are obliquely arranged from top to bottom along the direction close to the sewage drain, the slopes of the side walls on the two sides of the inner wall are steeper from front to back, in the present embodiment, an obtuse angle is formed between the outer wall of the annular gentle slope 11 and the outer wall of the annular drop slope 12, and an obtuse angle is formed between the inner wall of the flat slope 13 and the inner wall of the annular drop slope 12.

In this embodiment, on the one hand, by arranging the annular gentle slope 11 and the annular drop slope 12 which are arranged from top to bottom, an annular step structure with larger drop is formed on the inner wall of the liner tip 1, when water flows from the annular gentle slope 11 to the annular drop slope 12 in flushing, the inner wall of the liner tip 1 is suddenly steeped, and a drop with a certain height is formed between the annular gentle slope 11 and the flat gentle slope 13, the water flow generates gravitational potential energy by utilizing the angle drop and the height drop, on the other hand, as shown in fig. 5 to 8, the annular gentle slope 11 and the flat gentle slope 13 are all obliquely arranged from top to bottom in the direction close to the sewage outlet, the annular drop slope 12 is obliquely backwards inclined from top to bottom, so that the depth of the liner tip 1 is gradually increased from front to back, and the slope of the side walls on two sides of the inner wall (namely, the annular gentle slope 11 and the two side walls of the annular drop slope 12) is gradually changed from front to back, so that the gravitational potential energy generated on the two side walls of the water flow is further increased, the gravitational potential energy generated on the two side walls is further utilized, the speed of the water flow entering the sewage pipe is accelerated, and the sewage draining capacity is effectively improved, and the sewage draining capacity is ensured to have better sewage draining capacity when the sewage is less.

In addition, when the water flow is swirled into the liner tip 1, due to the annular step structure of the liner tip 1 and the slope arrangement of the side walls at two sides, the swirled water flow can form oblique swirling flow in the liner tip 1, the bottom of the swirling flow points to the sewage outlet, and the tensile force generated at the bottom of the swirling flow can rapidly pull the sewage in the liner tip 1 into the sewage pipe, so that better sewage discharging capability can be further ensured when the water quantity is less.

Referring to fig. 4, the annular drop slope 12 includes a front end wall surface 121 and a rear end wall surface 122, wherein the front end wall surface 121 forms a first angle α with an upward opening with a line in a vertical direction, and the rear end wall surface 122 forms a second angle β with a downward opening with a line in a vertical direction, wherein α is greater than or equal to β.

As a specific embodiment of the present utility model, α=β;

as a preferable specific implementation mode of the utility model, alpha is larger than beta, which is more beneficial to forming swirling flow which is obliquely arranged, and further improving the sewage discharge capacity.

20 DEG.gtoreq.alpha.gtoreq.15 DEG, 15 DEG.gtoreq.beta.gtoreq.10 DEG, exemplary alpha is 15 DEG, 17 DEG, 18 DEG or 20 DEG, but not limited thereto, exemplary beta is 10 DEG, 12 DEG, 14 DEG or 15 DEG, but not limited thereto.

When the values of alpha and beta are too large, the annular drop slope 12 is too inclined, the gravitational potential energy of flushing impulse is greatly weakened, and when the values of alpha and beta are too small, the annular drop slope 12 is in a vertical shape, and dirt enters the pipeline smoothly.

As shown in FIG. 4, the height H of the annular drop ramp 12 is 45mm or more to ensure sufficient height to form gravitational potential energy.

The height H of the annular drop slope surface 12 is 45-55 mm, so that the integral excessive height of the liner tip 1 is avoided while the sufficient height is ensured to form gravitational potential energy.

Referring to fig. 2, the inner wall of the liner 1 includes a front wall 141, a rear wall 142, and lateral walls 143 provided on both sides of the front wall 141, wherein the curvature of the front wall 141 > the curvature of the rear wall 142 > the curvature of the lateral walls 143, and the relative width distance L between both sides of the rear wall 142 ₁ Relative width distance L between two sides of front wall 141 ₂ 。

The curvature arrangement of each position of the inner wall and the relative width and distance arrangement on the front wall surface and the rear wall surface are more beneficial to forming swirling flow which is obliquely arranged, and the sewage discharge capacity is further improved.

Referring to fig. 5, the flat and gentle slope 13 is located below the water seal liquid level, and a shallow water seal area 41 is formed above the flat and gentle slope 13, and the dirt drop point is located on the shallow water seal area 41.

In this embodiment, the water storage below the toilet bowl forms the water seal, wherein, because the flat gentle slope 13 is located the water seal liquid level below, the water seal face 4 of water seal extends to the flat gentle slope 13 top, enlarged the area of water seal face 4 from this, the probability that the filth falls to non-water seal face 4 falls to reduce and glue just probability, reduce to wash, the blowdown degree of difficulty, locate the filth drop point on shallow water seal area 41 simultaneously, when guaranteeing that the filth can drop water cover 4, inhibit the filth and drop the splash problem that causes on the surface of water.

Referring to fig. 4, a third included angle γ, which is formed between the flat slope 13 and the line in the horizontal direction and is opened toward the rear wall 142, is an acute angle, preferably, γ is 10 ° to 15 °, and when the angle γ is too small, the flat slope 13 is approximately horizontal, so that water flow is difficult to smoothly enter the drain pipe, and when the angle γ is too large, the depth of the water seal formed at the position above the flat slope 13 is large, so that the shallow water seal region 41 is difficult to be formed, and water splashing is easy to occur.

Referring to FIG. 4, the depth h of the shallow water seal area 41 is 20nm not less than h > 0, and enough depth can ensure that dirt falls into the water of the shallow water seal area 41 instead of directly falling onto the flat slow slope 13, so that the probability of excrement sticking is reduced, and water splash is easily splashed onto a user due to excessive depth.

Referring to fig. 4, the distance W between the front and rear ends of the flat and slow slope 13 is 60 mm-70 mm, so that the formed water seal surface 4 has enough length, the water seal surface 4 is increased, the dirt falling point is more easily located on the water seal surface 4, and the sticky probability is reduced.

The toilet is a wall-hanging toilet.

Of course, the above-mentioned embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, so that all equivalent modifications made in the principles of the present utility model shall be included in the scope of the present utility model.
