Abstract

The invention discloses a high-temperature fan based on a heat insulation mechanism. The high-temperature fan comprises a motor and an impeller device, wherein a motor spindle is arranged on the motor; a driven shaft is arranged on the impeller device; the motor spindle is in transmission connection with the driven shaft; a heat insulation device is arranged between the motor spindle and the driven shaft; the heat insulation device comprises a connecting seat; the two ends of the connecting seat are fixedly connected with the motor spindle and the driven shaft respectively; and first heat insulation parts are arranged at the joint of the connecting seat and the motor spindle and the joint of the connecting seat and the driven shaft. According to the high-temperature fan based on the heat insulation mechanism, the first heat insulation parts are arranged between the motor and the impeller device to prevent heat of the impeller device from being transmitted to the motor from a transmission part, so that the heat of the motor during operation of the fan is greatly reduced, and the service life of the motor is guaranteed; and meanwhile, the structural strength of the transmission part between the motor and the impeller device is not changed, and the service life of the whole fan device is guaranteed.

Description

technical field [0001] The invention relates to the field of fan technology, in particular to a high-temperature fan based on a heat insulation mechanism. Background technique [0002] At present, the suction fan or blower used for cooking stoves or stoves in the market is often due to the short connecting shaft between the motor and the fan, and the flow of high-temperature gas in the fan impeller chamber makes the temperature of the impeller group too high, and the high temperature is transmitted from the drive shaft. However, when the temperature of the motor is too high, it will cause damage to the motor and cause losses. Even if a fan is installed at the fan end, the cooling efficiency is low and the heat conduction speed is fast, so it is easy to burn the motor. The cost is too high, and the vibration is relatively large during operation. Therefore, the invention patent with the publication number CN205297978U discloses a high-temperature-resistant fan, which can draw...
