Abstract

The invention relates to the technical field of exhaust fans and particularly relates to a conveniently-cleaned exhaust fan comprising a fan body, a driving shaft, a first rotating motor and a fan frame with a cylindrical cavity; the fan frame is fixedly connected with fixed rods, the fan body comprises fan blades and a turntable, guide holes are formed in the side wall of the turntable connected with the first rotating motor by the driving shaft, the first rotating motor is connected with one of the fixed rods, the fan blades are fixedly connected with the turntable, and the sides of the fan blades are provided with sliding rails; the fan blades are slidably connected with cleaning parts in which strip-shaped holes are further formed, the inner walls of the strip-shaped holes are provided with bulges in sliding fit with the sliding rails, and each cleaning part is further fixedly connected with a connecting line; the other fixed rod is fixedly connected with a second rotating motor on which a locating shaft is arranged, a through hole is formed in the center of the turntable, the locating shaft is rotatably connected with the turntable after passing through the through hole, and the connecting lines are fixedly connected with the locating shaft. By using the conveniently-cleaned exhaust fan, the problem that time and labor are wasted because an existing exhaust fan is required to be manually cleaned can be solved.

Description

technical field [0001] The invention relates to the technical field of exhaust fans, in particular to an exhaust fan that is easy to clean. Background technique [0002] Exhaust fans are mainly used for air exchange between indoors and outdoors, and now commonly used are wall exhaust fans installed on the wall. The exhaust fan must be cleaned after a long period of use, otherwise stains will accumulate on the exhaust fan and the inner wall of the fan frame containing the exhaust fan, which will nourish the production of bacteria. Because these exhaust fans are usually installed in a higher position on the wall, people standing on the ground can only reach the lower half of the exhaust fan frame inner wall at most, so it is difficult to complete the comprehensive cleaning of the fan frame inner wall. [0003] In order to solve the above problems, the Chinese patent No. CN201410300333.6 discloses a safety exhaust fan, which includes a carrier containing a cylindrical cavity, ...
