Circulation fan and its blade group

Abstract

The invention provides a circulating fan and a fan blade group of the circulating fan. The circulating fan at least comprises a shell body, a cover body, and a fan blade group. The shell body comprises a base seat, and the cover body and the shell body are jointed to form containing space. The fan blade group is arranged in the containing space. The fan blade group at least comprises a first impeller, a second impeller, a motor, and a plurality of magnetic components. The second impeller is arranged near the first impeller. The motor is fixedly arranged on the base seat of the shell body and connected with the first impeller to drive the first impeller to run. The magnetic components are arranged between the first impeller and the second impeller. With wind power generated by running of the first impeller and magnetic torque generated by magnetic eddy currents between the magnetic components, the second impeller is driven to run under non-contact force. According to the circulating fan and the fan blade group of the circulating fan, impellers with smaller fan blades are chosen to be used for being matched with the motor with smaller size, and thus effects that the size and power consumption are reduced, space configuration is simplified, and cost is reduced are achieved.

Description

technical field [0001] The invention relates to a circulation fan, in particular to a circulation fan driven by compound power and a blade set thereof. Background technique [0002] In recent years, with the rising awareness of environmental protection, energy conservation and carbon reduction policies have become the goal of public agencies and even private companies to strengthen research. Summer electricity saving is the current goal of global improvement and innovation. Therefore, organizations, enterprises, schools, and families have all begun to focus on reducing the frequency and time of air-conditioning use. In order to maintain air circulation and promote space utilization, various fans, circulation fans, and other products have begun to appear on the market. . [0003] Most of the existing fans use motors to drive the fan blades so that the fan blades rotate to generate air flow, thereby enhancing indoor convection and controlling the indoor temperature. Among th...

Problems solved by technology

[0005] The main purpose of the present invention is to provide a circulation fan and its fan blade set to solve the problem of using longer and larger fan blades and matching with a high-power and large-sized motor when the indoor convection demand of the existing fan increases. , resulting in a substantial increase in volume and power consumption, which fails to achieve the purpose of saving energy, and also increases the difficulty of space allocation and waste of costs.
