Problems solved by technology
Such fan blades are not conducive to the generation of wind, resulting in low flow rate, high power consumption and high noise of the existing mixed flow impeller
[0004] In this way, the user's use cost will be increased, and people's hearing will also be damaged.

Abstract
The invention discloses an efficient silent impeller machine. The impeller machine comprises a machine body with a blast cavity and an air cone, the air cone is provided with an air guide cavity, and the left end of the air guide cavity is small and the right end of the air guide cavity is large, and the air cone is detachably connected with the machine body. The machine body and the air cone can be processed independently and also can be independently replaced during maintenance, and the air cone can be stacked and stored, so that the storage space is small and the transportation cost is low. An impeller is arranged in the air guide cavity, blade bodies are arranged on the impeller; the blade bodies comprise root edges, front edges, top edges and rear edges, root arcs, average arcs and top arcs of the blade bodies project on the root conical surfaces, the average conical surfaces and the top conical surfaces respectively to form the root edges, average control lines and the top edges, the whole shape of each blade body is determined by the root edge, the average control line and the top edge. According to the comparison of experimental results, the efficiency of the fan can be greatly improved, and the specific A-weighted sound level can be reduced. The efficient silent impeller machine is used for mixed flow impeller machines.
Description
technical field [0001] The invention relates to a high-efficiency silent impeller. Background technique [0002] The existing machine body and air cone are made as a whole. As long as the machine body or air cone is poorly manufactured, it will be scrapped as a whole, so the processing accuracy is very high, which will undoubtedly increase the manufacturing cost, and the machine body or air cone will occur during use. If it is damaged, it must be replaced as a whole, resulting in long maintenance and repair time and high costs. The one-piece body and wind cone are heavy and bulky, which is not convenient for transportation and storage. [0003] The impeller machine relies on the impeller to generate airflow. The impeller includes the impeller hub, and the impeller hub is provided with a plurality of fan blades. The shape of the fan blades of the existing mixed flow impeller machine is flat. Such fan blades are not conducive to wind generation, resulting in low flow rate, h...
