The utility model discloses an efficient combined type vertical axis fan wind wheel system capable of being started at low speed and providing lift force. The efficient combined type vertical axis fan wind wheel system comprises a main shaft, lift-force-type blades, resistance-type blades and connecting rods. The lift-force-type blades are connected with the main shaft through the connecting rods and evenly distributed in the circumferential direction of the main shaft, the section of the upper connecting rod connected with the lift-force-type blades is a wing-shaped face with the outer-side section being larger than the inner-side section in the direction where the radius increases, and the lift-force-type blades can generate upward pneumatic lift force as a wind wheel rotates; the resistance-type blades are arranged between the lift-force-type blades and the main shaft, and the resistance-type blades are cylindrical faces with the upper ends and the lower ends closed; when the number of the resistance-type blades is one half of or equal to the number of the lift-force-type blades, the resistance-type blades and the lift-force-type blades share the upper connecting rod and the lower connecting rod; when the number of the resistance-type blades is not equal to the number of the resistance-type blades, an upper connecting rod and a lower connecting rod are additionally arranged to be connected to the main shaft. According to the efficient combined type vertical axis fan wind wheel system, by adding the upper connecting rod with the wing-shaped surface, the pressure of air in the center of the wind wheel is maintained, and pressure, to a supporting face, from the wind wheel system is reduced; the blade profile of the resistance-type blades is improved, the air flow organization structure is optimized, and the operation efficiency of a fan is improved while the starting wind speed of the fan is reduced.
