Electric fan and terminal device

A terminal device, comprising an electric fan;

• wherein the electric fan comprises a motor assembly, an impeller assembly, and a diffuser assembly;
• wherein the motor assembly comprises an output shaft, a bracket, and a stator-rotor component;
• the bracket and the stator-rotor component are both sleeved on the output shaft;
• the bracket has an accommodation region, and the stator-rotor component is disposed in the accommodation region;
• the impeller assembly is disposed on a side of the stator-rotor component and is sleeved on the output shaft;
• the diffuser assembly is sleeved on the output shaft and is disposed between the stator-rotor component and the impeller assembly;
• wherein a part of gas passing through the diffuser assembly is configured to flow toward an outside of the bracket, and another part of the gas is configured to flow toward an interior of the stator-rotor component;
• wherein the bracket comprises a bracket body and a support member;
• the bracket body is sleeved on the output shaft;
• the support member is disposed on a side of the bracket body close to the diffuser assembly, and the support member is connected to the diffuser assembly and the bracket body, respectively;
• wherein the motor assembly further comprises a connecting member;
• the connecting member is sleeved on the output shaft and is disposed on a side of the support member away from the bracket body;
• the connecting member is disposed on a radial inner side of the diffuser assembly;
• the connecting member is connected to the support member and the diffuser assembly, respectively;
• wherein the support member comprises at least one support arm and a support connection;
• the at least one support arm is disposed on a side of the diffuser assembly close to the bracket body;
• the support connection is disposed on a side of the at least one support arm away from the diffuser assembly, and the support connection is connected to the at least one support arm and the bracket body, respectively;
• wherein the support arm is recessed toward the output shaft;
• wherein an end of the support arm away from the support connection is connected to the connecting member;
• and
• wherein, in the extension direction of the axis of the output shaft, a positive projection of the support arm overlaps with a positive projection of a connecting arm.
