[0002] As an efficient aerobic fitness equipment, the rowing machine is favored by fitness enthusiasts because it can simulate rowing movements and comprehensively exercise multiple muscle groups of the human body, including the legs, buttocks, back, shoulders and arms. There are many types of rowing machines on the market. According to the different ways of generating resistance, they can be mainly divided into wind resistance rowing machines, magnetic resistance rowing machines and water resistance rowing machines.

[0003] Existing water-resistance rowing machines usually rotate the blades in the water tank, using the resistance of the water to provide the user with the resistance required for exercise. The water resistance can naturally change with the changes in rowing speed and strength. However, current water-resistance rowing machines mostly use a single water bucket structure. When the blades rotate in the water, the water flow is strongly disturbed, which easily generates a large impact force and vortex, thereby causing the sound of rushing water, causing noise, disturbing people around, and affecting the user experience and comfort.

[0004] Therefore, it is necessary to design a double-layer water bucket diversion and pressurized rowing machine that can use water as resistance for exercise while realizing water circulation through a double-layer water bucket, thereby reducing the sound of water, reducing noise, and improving user comfort.
