When the locking surface cover 2 is installed on the main body 1, there is a gap 16 between the pressing rib 21 and the upper end surface of the main body 1, and the gap 16 is slightly larger than the thickness of the cylinder wall 6, so that the pressing rib 21 and the main body 1 are clamped in on the cylinder wall 6. In order to ensure sealing and prevent the water in the bathtub from flowing out from the gap between the cylinder wall 6 and the water return device, a sealing gasket 7 and a sealing ring 10 are provided between the main body 1 and the locking surface cover 2, wherein, in the main body 1 A sealing gasket 7 is provided at the upper end of the locking face cover 2, and a sealing ring 10 is set on the locking surface cover 2. When the water return device is installed on the cylinder wall 6, the main body 1 and the pressure ribs 21 clamp the cylinder wall 6, and the sealing gasket 7 is squeezed between the main body 1 and the cylinder wall 6 to prevent the water entering the water return device. The outer side seeps out; while the locking surface cover 2 runs through the cylinder wall 6, and the sealing ring 10 is sandwiched between the locking surface cover 2 and the cylinder wall 6, which can prevent the water in the bathtub from going to the gap between the water return device and the cylinder wall 6 infiltrate. In addition, the main body 1 is provided with a stepped surface 22 between the water inlet section 15 and the internal thread 13. In order to prevent the formation of water accumulation on the stepped surface 22, the stepped surface 22 is provided with an anti-water accumulation pad 11 to lock the surface cover. The lower end of 2 presses the anti-water accumulation pad 11 to make it closely adhere to the stepped surface 22 .

In order to prevent particulate matter from entering the water pump, as shown in Figures 5 and 6, the water return device also includes a grid surface cover 3, wherein the grid surface cover 3 is arranged on the side of the locking surface cover 2 facing away from the main body 1, It protrudes from the cylinder wall 6 and is fastened on the locking surface cover 2, which can be rotated and removed. The opening area 17 of the mesh surface cover 3 is in the center, and a plurality of triangular through holes 18 are evenly opened in the opening area 17. The edge of the mesh surface cover 3 is not opened, and the area of the opening area 17 is not less than The maximum cross-sectional area of the water inlet section 15 ensures that water will not accumulate in the unopened area on the edge of the grid surface cover 3 . In addition, the top of the support rib 14 is in clearance fit with the lower end surface of the grid surface cover 3 , which can play a supporting role and prevent the grid surface cover 3 from being excessively deformed.

Therefore, as shown in FIG. 7 , the cylinder wall 6 of the bathtub is inclined, and the inclination angle of the cylinder wall 6 is b, that is, the angle between the cylinder wall and the vertical plane is b, and the value of b is 8°. The water device is installed vertically on the cylinder wall 6, and the included angle c between the axis of the inner cavity 4 and the horizontal plane is formed. It can be known that c is equal to b, and both are 8°. In this embodiment, the included angle between the water inlet section 15 and the axis of the inner cavity 4 is a, and the angle value of a is 8°. Therefore, when the water return device is installed on the cylinder wall 6, the water inlet section 15 is the most The lower side is horizontal, that is, between point A and point B is horizontal, so that the bottom of the inner cavity 4 cannot store water, or is discharged in real time, so as to achieve the purpose of no water accumulation.

Embodiment 2

Please refer to the second embodiment of the water return device and the bathtub of the present invention in FIG. 8 . The main difference between this embodiment and the first embodiment is that the second connecting channel is blocked by the blocking plate.

Specifically, as shown in FIG. 8 , the main body 1 is provided with a blocking plate 20 between the inner cavity 4 and the second connection channel 8 , which is connected to the support ribs 14 and is perpendicular to each other, which can block the backflow of water from entering the second connection. Channel 8, so that the water return device can only lead out water flow in one direction.

Embodiment 3

The third embodiment of the water return device and the bathtub of the present invention. The main difference between this embodiment and the first embodiment is that the included angle between the water inlet section and the axis of the inner cavity is greater than the inclination angle of the cylinder wall.

Specifically, the inclination angle of the cylinder wall of the bathtub is 8°, the included angle between the water inlet section and the axis of the inner cavity is 10°, and the included angle between the water inlet section and the axis of the inner cavity is greater than the inclination angle of the cylinder wall. When the water return device is installed on the cylinder wall, the water inlet section is downward from point A to point B, which also prevents water from being stored at the bottom of the inner cavity, or is discharged from the water return port in real time to achieve the purpose of no water accumulation.

In combination with the above embodiments, the water return device of the present invention uses the inclined water inlet section to draw out the water at the bottom of the inner cavity, so as to avoid the generation of accumulated water and greatly improve the user experience. The included angle between the water inlet section and the axis of the inner cavity of the utility model is greater than or equal to the inclination angle of the cylinder wall, which compensates the inclination angle of the cylinder wall, so that the installed water inlet section on the lower side is horizontal or in the direction of the water outlet.
