  • the bathtub further comprises the above mentioned water backflow device fixed on the bathtub wall.
  • the angle formed between the water intake section and the axis of the inner cavity is greater than or equal to the inclination angle of the bathtub wall, which compensates the inclination angle of the bathtub wall, so that after being installed, the water intake section in a lower position is positioned horizontally or is inclined downward toward the water outlet port, therefore preventing water from being accumulated at the bottom of the inner cavity.
  • the bathtub includes an inclined bathtub wall 6 on which a water backflow device for water returning is provided.
  • the water backflow device includes a main body 1 provided with an inner cavity 4.
  • the main body 1 is provided with a water backflow port 19 for communicating the inside of the inner cavity 4 with the outside of the inner cavity 4.
  • the side wall of the inner cavity 4 includes a water intake section 15 extending from the water backflow port 19 to the bottom of the inner cavity 4 and having an inclined configuration.
  • the water intake section 15 may discharge the water accumulated at the bottom of the inner cavity 4 out of the inner cavity 4. Therefore, the water backflow device discharges the water accumulated at the bottom of the inner cavity 4 by the inclined water intake section 15, thereby preventing the water from accumulating, preventing the generation of stink and bacteria breeding, and greatly improving the user experience.
  • the inner side wall of the inner cavity 4 constitutes the above-mentioned water intake section 15 which has the shape of a horn facing the water backflow port 19.
  • an internal thread 13 and a support rib 14 are provided at the water backflow port 19 of the main body 1, the support rib 14 extends upward and spans the water backflow port 19.
  • the main body 1 is also provided with a first connecting channel 9 and a second connecting channel 8 for connecting to a water pump or other pipelines.
  • the first connecting channel 9 and the second connecting channel 8 are communicated with the inner cavity 4, respectively, so that the main body 1 forms a three-way structure which can direct the backflow water in two directions.
  • the water backflow device further includes a locking cover 2 arranged on the main body 1.
  • the locking cover 2 is of annular shape, the lower end thereof is provided with an external thread 12 which can be matched with an internal thread 13 on the main body 1, and the upper end of the locking cover 2 is provided with a pressing rib 21.
  • a void 16 is formed between the pressing rib 21 and an upper end face of the main body 1, which is slightly larger than the thickness of the bathtub wall 6, so that the pressing rib 21 and the main body 1 are clamped on the bathtub wall 6.
  • a sealing gasket 7 and a sealing ring 10 are arranged between the main body 1 and the locking cover 2.
  • the sealing gasket 7 is arranged at the upper end of the main body 1, and the sealing ring 10 is arranged around the locking cover 2.
  • the locking cover 2 extends through the bathtub wall 6, and the sealing ring 10 is sandwiched between the locking cover 2 and the bathtub wall 6, so that water in the bathtub can be prevented from leaking through a gap between the water backflow device and the bathtub wall 6.
  • the main body 1 is provided with a stepped surface 22 between the water intake section 15 and the internal thread 13.
  • a water accumulation preventing rubber pad 11 is provided at the stepped surface 22, and the lower end of the locking cover 2 presses the water accumulation preventing rubber pad 11 tightly against the stepped surface 22.
  • the water backflow device further includes a grid cover 3 which is arranged on the side of the locking cover 2 facing away from the main body 1 and protrudes from the bathtub wall 6.
  • the grid cover 3 is fitted to the locking cover 2, and can be rotatably detached therefrom.
