The sink body comprises a bottom wall and a sink wall extending upward from and surrounding the bottom wall, an annular water flow channel is provided at a top portion of the sink wall, the annular water flow channel is provided with at least one water inlet hole communicated with an external water inlet pipe, and the bottom wall is provided with a drain hole. The sink flat is arranged above the sink body and comprises an annular flange panel and an insert portion extending downward along an inner wall of the flange panel, the insert portion extends into the sink body, an annular water outlet communicated with the water flow channel is formed between the insert portion and the sink wall, and the annular water outlet sprays water along an inner wall of the sink wall. ## Claims ### Claim 1 A novel sink, comprising: a sink body, comprising a bottom wall and a sink wall extending upward from and surrounding the bottom wall, an annular water flow channel being provided at a top portion of the sink wall, the annular water flow channel being provided with at least one water inlet hole communicated with an external water inlet pipe, and the bottom wall being provided with a drain hole; and a sink flat, arranged above the sink body and including an annular flange panel and an insert portion extending downward along an inner wall of the annular flange panel, the insert portion extending into the sink body, an annular water outlet communicated with the water flow channel being formed between the insert portion and the sink wall, and the annular water outlet spraying water along an inner wall of the sink wall. ### Claim 2 (depends on 1) The novel sink according to claim 1, wherein the sink wall comprises a sink wall body, a trim extending outward along a top portion of the sink wall body, and a vertical connecting wall formed at a tail end of the trim, the trim and the vertical connecting wall forming the annular water flow channel, and the trim or the vertical connecting wall has the water inlet hole therein. ### Claim 3 (depends on 2) The novel sink according to claim 2, wherein a section line of the trim in a direction of a centerline of the sink body is an arc-shaped curve or an inclined straight line. ### Claim 4 (depends on 1) The novel sink according to claim 1, wherein at the top portion of the sink wall, an outer side wall of the sink wall extends upward relative to an inner side wall of the sink wall, the annular water flow channel is formed between the inner side wall and the outer side wall, an arc transition curved surface or an inclined guide surface is formed between the inner side wall and the outer side wall, and the water inlet hole is formed in the outer side wall. ### Claim 5 (depends on 1) The novel sink according to claim 1, wherein the insert portion extends downward in a vertical direction; alternatively, in an insertion direction, the insert portion is gradually inclined toward a side where the sink wall is located. ### Claim 6 (depends on 5) The novel sink according to claim 5, wherein when the insert portion is inserted into the sink body, a tail end of the insert portion extends downward through the annular water flow channel, and the annular water outlet is formed between the insert portion and the sink wall below the annular water flow channel. ### Claim 7 (depends on 1) The novel sink according to claim 1, wherein the water inlet hole is obliquely arranged in the sink wall, and a water inlet direction of the water inlet hole is obliquely upward. ### Claim 8 (depends on 7) The novel sink according to claim 7, wherein the sink flat further comprises a block disposed opposite to the water inlet hole, the block blocking water flowing out of the water inlet hole into the annular water flow channel or the annular water outlet. ### Claim 9 (depends on 8) The novel sink according to claim 8, wherein the block is formed between the flange panel and the insert portion, and a section line of the block in a direction of a centerline of the sink body is a convex arc-shaped curve or an inclined straight line. ### Claim 10 (depends on 1) The novel sink according to claim 1, wherein the flange panel is seamlessly welded to the sink wall. ### Claim 11 A sink flusher, the sink flusher being annular and comprising: an inner wall; an outer wall, arranged on an outer side of the inner wall, an upper end of the outer wall being connected with an upper end of the inner wall, a lower end of the outer wall being separated from a lower end of the inner wall, the lower end of the inner wall extending beyond the lower end of the outer wall, and an annular water flow channel being formed between the inner wall and the outer wall; and a water inlet pipe, formed on the inner wall or the outer wall and communicated with the annular water flow channel. ### Claim 12 (depends on 11) The sink flusher according to claim 11, wherein a section line of the inner wall in a direction of a centerline of the sink flusher is an arc-shaped curve or an inclined straight line. ### Claim 13 (depends on 11) The sink flusher according to claim 11, wherein the lower end of the inner wall extends downward in a vertical direction; or in an extending direction, the lower end of the inner wall is gradually inclined towards a side where the outer wall is located. ### Claim 14 (depends on 11) A novel sink, comprising: a sink body; and the sink flusher according to claim 11, wherein the inner wall and the outer wall of the sink flusher are both inserted into the sink body, and water in the annular water flow channel washes a side wall of the sink body. ### Claim 15 (depends on 14) The novel sink according to claim 14, wherein an annular mounting groove is provided at a top portion of the sink body, the inner wall and the outer wall of the sink flusher are both inserted into the annular mounting groove, the lower end of the inner wall extends through a bottom portion of the annular mounting groove, and an annular water outlet is formed between the inner wall and the side wall of the sink body.
