Air purifying device

Abstract

The invention discloses an air purifying device which comprises a fixing frame and a rotating impeller. Fixing corners are simultaneously arranged at the four corners of the left end face and the right end face of the fixing frame. Bolt holes are formed in the fixing corners. A rotating groove extending upwards is formed in the fixing frame, wherein a through opening of the rotating groove faces downwards. The lower end of the rotating groove is rotationally provided with a rotating shaft, and the rotating impeller is installed on the rotating shaft. A containing cavity is formed in the position, located on the right side of the rotating groove, in the fixing frame. The right end of the rotating shaft extends in the containing cavity and is fixedly provided with a second cone tooth wheel, and a first tooth wheel cooperatively connected with the second tooth wheel is further installed in the containing cavity. A first motor is fixedly installed at the right end of the containing cavity, and the first tooth wheel is fixedly connected with a transmission shaft of the first motor.

Description

Technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device. Background technique [0002] With the continuous development of society, the degree of air pollution is getting higher and higher. Air purifiers can adsorb, decompose or transform various air pollutants, effectively improve air quality and are widely used. The impeller is an important component in the air purifier. It is mainly driven by the motor to rotate at a high speed. Because some large air purification equipment has high power and the motor is directly connected to the impeller, it is easy to accidentally turn on the motor during the maintenance of the air purification equipment. Injury to maintenance personnel, and in the case of emergency power failure during maintenance, the impeller will continue to rotate for a period of time due to inertia. Therefore, the impeller setting mode of ordinary air purification equipment is too simple and e...

Problems solved by technology

The impeller is an important component of the air purifier, which is mainly driven by the motor to rotate at high speed. Since some large-scale air purification equipment has a large power and the motor is directly connected to the impeller, it is easy to turn on the motor accidentally during maintenance of the air purification equipment. It will cause harm to the maintenance personnel, and in the event of an emergency power failure during the maintenance process, the impeller will continue to rotate for a period of time due to inertia. Therefore, the impeller setting mode of ordinary air purification equipment is too simple and emergency Poor ability, there is a big security risk
