Background
Rowing machines are machines used for training purposes to simulate the movement of water racing boats. Indoor racing boat games have become a professional game. Indoor rowing machines, also commonly referred to as dynamometers (commonly known colloquially as ergs or ERGO abroad), measure the power consumed by a sportsman in sports. The rowing machine has good effect on strengthening muscles of legs, waists, upper limbs, chests and backs. Every stroke, the upper limbs, the lower limbs, the waist, the abdomen and the back can complete one-time complete contraction and extension in the process, and the aerobic exercise effect of whole body muscles can be achieved. Especially for people with more fat in waist, abdomen and upper arm, the rowing machine can bring unexpected body shaping effect to people.
The existing water resistance rowing machine is generally provided with a circular water tank with a rotating blade, water and other fluids are filled in the water tank to serve as a resistance source of the rotating blade, and the rotating blade drives water flow to do circular motion. When the strength training device is used, the driving devices such as the driving belt and the like are pulled to drive the rotating blades to overcome the resistance of water flow to rotate, and meanwhile, the water flow is driven to rotate together, so that the strength training effect is achieved. However, because the water flow has inertia, after the rotating blade rotates once, the water flow can continue to rotate due to the inertia and cannot keep a static state, so that the force required by the previous pulling is inconsistent with the force required by the next pulling, and is usually larger than the force required by the next pulling, thereby causing instability of training strength and poor training effect. This problem is most severe when the round tank is placed horizontally.

Detailed Description
In the description of the present invention, the directions or positional relationships indicated by "upper", "lower", etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the scope of the present invention.
As shown in fig. 1 to 4, the present invention discloses a water tank 100 of a water resistance rowing machine, which includes a fluid chamber and a rotary blade 110, wherein the rotary blade 110 is disposed in the fluid chamber and is used for rotating in the fluid chamber, and the fluid chamber is a non-circular chamber. Specifically, the fluid chamber is a non-circular chamber, which means that when the water tank 100 is horizontally placed, the horizontal cross-section of the fluid chamber is non-circular.
Specifically, the inner cavity wall of the fluid chamber of the present embodiment is provided with first blocking ribs (121, 131).
Specifically, the first blocking ribs (121, 131) of the present embodiment are perpendicular to the inner cavity wall of the fluid chamber, and the blocking force of the first blocking ribs (121, 131) provided in this way to the water flow from two opposite directions is the same, so that the rotating direction of the rotating blade 110 does not need to be considered, and the assembly is simple.
Specifically, the fluid chamber of the present embodiment is an elliptical chamber.
Specifically, the overall shape of the water tank 100 of the present embodiment is also elliptical, matching the fluid chamber; the water tank comprises an upper shell 120 and a lower shell 130, and the fluid chamber is formed by hermetically combining the upper shell 120 and the lower shell 130; first blocking ribs (121, 131) are provided on the lower case 130 and the upper case 120. (the first blocking ribs may also be provided only on the lower housing 130.)
Specifically, the lower housing 130 of the present embodiment includes a horizontal bottom housing 133 and arc-shaped side housings (124, 134), the upper housing 120 includes a horizontal top housing 123 and arc-shaped side housings (124, 134), the arc-shaped side housings (124, 134) are respectively provided with a connecting portion (122, 132), the lower housing (120, 130) and the lower housing (122, 132) are hermetically connected together through the connecting portion (122, 132), and a sealing ring 150 is further disposed between the connecting portions (122, 132).
