[0045] The sealing rubber ring 9 is installed between the first diversion pipe 2 and the third diversion pipe 10. When the roller 4 meshes with the spur gear rack 3, the first diversion pipe 2 is accurately controlled to slide downward; when the first diversion pipe 2 slides downward, the sealing rubber ring 9 exposes the holes on the third diversion pipe 10, and the liquid flows from the second diversion pipe 8 through the holes on the third diversion pipe 10 into the first diversion pipe 2, and then the liquid flows out from the diversion cover 1; the spring 11 is arranged inside the second diversion pipe 8.

[0046] Moreover, a sealed spherical ball is installed inside the second diversion tube 8 to function as a check valve. When the third diversion tube 10 moves upward under the action of the spring 11, a negative pressure is generated inside the second diversion tube 8, causing the sealed spherical ball 12 to move upward, and the liquid flows from the fourth diversion tube 13 into the second diversion tube 8.

[0047] In summary, when in use, the utility model drives the roller 4 to mesh with the straight tooth rack 3 to transfer power between the meshing gears, accurately drives the pressure rod connected to the diversion cover 1, and the pressure rod generates pressure to accurately control the amount of dishwashing liquid flowing out, which has good practicability.
