Novel air blowing device for air conditioner

Abstract

The invention relates to a novel air blowing device for an air conditioner. The novel air blowing device comprises a shell. A motor is arranged in the shell. A rotary shaft is connected to the output shaft end of the motor. An impeller is arranged at the right end of the rotary shaft. An annular gear is fixedly arranged on the rotary shaft. A top rod and a bottom rod are arranged on the top wall and the bottom wall of the shell respectively. A top gear and a bottom gear are arranged on the top rod and the bottom rod respectively. A top transmission rod and a bottom transmission rod are arranged on the top gear and the bottom gear respectively and provided with a top blade and a bottom blade respectively. The vertical side wall of the shell comprises an inner-layer body and an outer-layer body. The upper portion of the inner-layer body and the lower portion of the outer-layer body are provided with multiple inner vent holes and multiple outer vent holes respectively. An annular dust filter screen is arranged between the middle of the inner-layer body and the middle of the outer-layer body. By the adoption of the structure, heat generated in the operation process can be effectively dissipated, the use performance of the air blowing device is greatly improved, and the service life of the air blowing device is greatly prolonged.

Description

technical field [0001] The invention relates to a novel air-conditioning blower device. Background technique [0002] Automobile air-conditioning blower device is a very important part in the automobile air-conditioning system. It is used to provide suitable wind flow for the automobile air-conditioning system. The traditional automobile air-conditioning blower device includes a motor inside the casing and a The impeller is connected to the rotating shaft, and the impeller rotates under the drive of the motor to adjust the air flow speed and flow volume of the air conditioning system. [0003] But for existing automobile air-conditioning blower device, its existing problem is, after the motor in the blower device runs for a long time, it can produce a large amount of heat, and be limited to the restriction on structural design, this heat If it cannot be released in time, it will have a great impact on the motor, and will reduce the performance and service life of the blower...
