Abstract

The invention discloses a hot air circulating fan. The hot air circulating fan comprises a base, a heating device and a circulating device; a supporting frame is fixedly connected to the upper surfaceof the base, a heater motor is fixedly connected to the supporting frame, the heating device is connected to the heater motor, a conveying pipeline is communicated between the heating device and thecirculating device, an air inlet cover is arranged on the heating device, a first filter net is arranged in the air inlet cover, an air outlet cover is arranged on the circulating device, a second filter net is arranged on the air outlet cover, the air inlet cover and the air outlet cover are each composed of a first cover body and a second cover body, a first cavity and a second cavity are symmetrically formed in the first cover body, and a first convex block and a second convex block are symmetrically arranged on the second cover body. The circulating fan is simple in structure and rapid andconvenient to use, the filter nets in the covers can be conveniently cleaned and replaced, air inlet and outlet speed can be improved, and the work efficiency of the hot air circulating fan is improved.

Description

Technical field [0001] The invention relates to the technical field of circulating fans, in particular to a hot air circulating fan. Background technique [0002] Circulating hot air blowers have a wide range of application prospects in electronics, food, pharmaceuticals, printing, packaging, cleaning, heat treatment and other industries. Circulating hot air blowers are the first choice for upgrading and upgrading of modern industrial heat sources. They are hot air conveying furnaces, drying furnaces, ovens, The best hot air source configuration for packaging machines and other automated machinery, but the existing hot air circulation fan is in use in order to avoid [0003] Some viscous or fibrous substances in the air enter the hot air circulation fan, which will affect the normal operation of the hot air circulation fan. Covers will be set at the air inlet and outlet respectively, and filters are installed in the cover to avoid stickiness or fibers in the air. Substances enter ...
