More Information
Summary:The utility model discloses an impeller separation type low-noise air pump which comprises a pump shell, an air inlet cavity arranged inside the pump shell, a motor arranged inside the air inlet cavity, a low-pressure buffer cavity arranged outside the air inlet cavity, and a first air duct communicated with the air inlet cavity. The high-pressure buffer cavity is arranged outside the low-pressure buffer cavity, the first transmission wheel is connected with the motor through a transmission shaft, the second transmission wheel is connected with the first transmission wheel through a transmission belt, and the impeller is connected with the second transmission wheel through a transmission shaft. The device has the advantages that the working rotating speed is kept, meanwhile, the low-noise effect can be achieved, the use experience is improved, meanwhile, the cooling effect on the motor can be achieved, and the situation that the service life of the motor is affected due to serious heating is avoided. 本实用新型公开了
