Combination type blade wheel

Abstract

The invention relates to a combined impeller, which comprises a shell, a plurality of blades, a ring body and a shaft lever, wherein the shaft lever is arranged on the center of the inner portion of the shell, the outer edge of the shell is circularly equipped with a plurality of blades and is arranged on a same shaft with the shaft lever, a wind guide slot is formed between the blades, the ring body is arranged on the air outlet end of the wind guide slot and is arranged on the same shaft with the shaft lever, the wind guide slot is divided into an inner wind guide slot and an outer wind guide slot by the ring body, the ring body is capable of smoothly flowing, an inner turbocharged blade and an outer turbocharged blade are capable of being arranged in each inner wind guide slot and each outer wind guide slot to reduce an outlet area, thereby achieving the effect of increasing wind pressure and inhibiting blown air to rebound to the wind guide slot, and the combined impeller uses a combined type to overcome the interfere of components, thereby being not easy to demould.

Description

technical field [0001] The invention relates to an axial flow impeller structure. Background technique [0002] Existing impeller 4, with reference to shown in Figure 6, described kind of impeller 4 has a hollow housing 41. The center of described housing 41 is provided with a shaft 44, and the periphery of described housing 41 and described The shaft rod 44 is coaxial, and the periphery of the housing 41 is provided with several blades 42, and the air guide groove 45 is formed between the blades 42 and the blades 42. Accordingly, when the existing impeller 4 rotates, the air will be drawn from the The front edge of the blade 42 guides into the guide air guide groove 45 and blows out to the rear edge, but the air guide groove 45 of this axial flow impeller 4 is equal in width, so the outlet area 450 is wider. For cooperation, refer to Fig. 7 China New Patent Certificate No. As shown in the radiating blades of ZL200320102753.0, although the outlet end of the air guide groove...

[0002] Existing impeller 4, with reference to shown in Figure 6, described kind of impeller 4 has a hollow housing 41. The center of described housing 41 is provided with a shaft 44, and the periphery of described housing 41 and described The shaft rod 44 is coaxial, and the periphery of the housing 41 is provided with several blades 42, and the air guide groove 45 is formed between the blades 42 and the blades 42. Accordingly, when the existing impeller 4 rotates, the air will be drawn from the The front edge of the blade 42 guides into the guide air guide groove 45 and blows out to the rear edge, but the air guide groove 45 of this axial flow impeller 4 is equal in width, so the outlet area 450 is wider. For cooperation, refer to Fig. 7 China New Patent Certificate No. As shown in the radiating blades of ZL200320102753.0, although the outlet end of the air guide groove 45 is provided with booster vanes 47 to reduce the width of the outlet area 450, but because the blades 42 of the impeller 4 are arranged radially, the outlet area of ​​the air guide groove 45 450 will gradually widen toward the tail end of the blade 42, so the outlet area 450 at the tail end of the blade 42 is also wider, so it is easy to cause the air blown out by the blade 42 to bounce back to the air guide groove, the wind pressure is also poor, and the flow field is also relatively chaotic.
