A body cleaning tool is further provided.

First claim

1 . A body cleaning head comprising:
an outer case provided with a suction port and provided therein with a reflow passage communicating with the suction port; and a water pipe assembly provided within the reflow passage, wherein the water pipe assembly includes a pipe bracket fixedly provided in the outer case, a water discharge hose is inserted and fitted within the pipe bracket and an end of the water discharge hose adjacent to the suction port is protruded from the pipe bracket, and around the end an elastic body and a slide sleeve are provided, the elastic body is located between the pipe bracket and the slide sleeve, the slide sleeve is axially movable relative to the pipe bracket under an action of the airflow pressure in such a manner that the elastic body presses the water discharge hose and inner diameter of a portion of the water discharge hose corresponding to the elastic body is varied with the airflow pressure.

2 . The body cleaning head according to claim 1 , wherein the slide sleeve is a conical sleeve, and an end with a smaller diameter is provided adjacent to the suction port of the outer case.

3 . The body cleaning head according to claim 1 , wherein, an annular slot is formed in the inner wall of the slide sleeve, the elastic body is placed in the annular slot, and an end of the pipe bracket is inserted into the annular slot and abuts against the elastic body.

4 . The body cleaning head according to claim 3 , wherein the elastic body is an elastic ring, and the maximum diameter of the annular slot is comparable with the outer diameter of the elastic ring.

5 . The body cleaning head according to claim wherein the elastic body includes a plurality of elastic blocks.

6 . The body cleaning head according to claim 1 , wherein a water outlet of the water discharge hose is located in the outer case, and the suction port of the outer case is provided at a distance away from the water outlet of the water discharge hose along an axial direction.

7 . The body cleaning head according to claim 1 wherein the distance by which the suction port of the outer case is separated from the water outlet of the water discharge hose along the axial direction is less than or equal to a spray distance of the water outlet.

8 . The body cleaning head according to claim 1 , wherein the distance by which the suction port of the outer case is separated from the water outlet of the water discharge hose along the axial direction is different from the spray distance by 1 to 2 cm.

9 . The body cleaning head according to claim 1 , wherein the elastic body is made from a rubber material.

10 . A body cleaning tool comprising a water supply motor and a suction motor, and further comprising a body cleaning head according to claim 1 , wherein the water supply motor communicates with the water discharge hose, the suction motor communicates with the reflow passage of the body cleaning head, ambient air and water flow sprayed from the water discharge hose can be drawn back into the cleaning tool by the suction motor through the reflow passage.

11 . The body cleaning head according to claim 2 , wherein, an annular slot is formed in the inner wall of the slide sleeve, the elastic body is placed in the annular slot, and an end of the pipe bracket is inserted into the annular slot and abuts against the elastic body.

12 . The body cleaning head according to claim 11 , wherein the elastic body is an elastic ring, and the maximum diameter of the annular slot is comparable with the outer diameter of the elastic ring.

13 . The body cleaning head according to claim 3 , wherein the elastic body includes a plurality of elastic blocks.

14 . The body cleaning head according to claim 3 , wherein the elastic body is made from a rubber material.

15 . The body cleaning head according to claim 2 , wherein a water outlet of the water discharge hose is located in the outer case, and the suction port of the outer case is provided at a distance away from the water outlet of the water discharge hose along an axial direction.

16 . The body cleaning head according to claim 2 , wherein the distance by which the suction port of the outer case is separated from the water outlet of the water discharge hose along the axial direction is less than or equal to a spray distance of the water outlet.

17 . The body cleaning head according to claim 2 , wherein the distance by which the suction port of the outer case is separated from the water outlet of the water discharge hose along the axial direction is different from the spray distance by 1 to 2 cm.

18 . The body cleaning head according to claim 3 , wherein a water outlet of the water discharge hose is located in the outer case, and the suction port of the outer case is provided at a distance away from the water outlet of the water discharge hose along an axial direction.

19 . The body cleaning head according to claim 3 , wherein the distance by which the suction port of the outer case is separated from the water outlet of the water discharge hose along the axial direction is less than or equal to a spray distance of the water outlet.

20 . The body cleaning head according to claim 3 , wherein the distance by which the suction port of the outer case is separated from the water outlet of the water discharge hose along the axial direction is different from the spray distance by 1 to 2 cm.
