Ventilating fan with air filter structure

Abstract

The invention discloses a ventilating fan with an air filter structure. The ventilating fan comprises a shell, a collecting groove and a second filter mechanism. A ventilation opening is formed in a side face of the shell, a blind is connected into the ventilation opening, a back plate is connected to the back face of the shell, an inner cavity is fixed into the shell, a first filter mechanism ismounted in the inner cavity, a purifying mechanism is mounted on the back face of the first filter mechanism, and the collecting groove is formed in the surface of the bottom end of the inner cavity.Through arranging of diameters of inner meshes between a first filter plate and a second filter plate, impurities with different diameters mixed up with air sucked in by the ventilating fan are filtered, therefore the problems that due to large impurity particles, the interior of the purifying mechanism is blocked, the direction of inner air flowing in the purifying mechanism is affected, and thepurifying efficiency of the purifying mechanism is affected can be solved, and due to arranging of the filter plates, convenience is provided for operation of purifying work of purifying equipment.

Description

technical field [0001] The invention relates to the technical field of high-tech industrial ventilation, in particular to a ventilation fan with an air filtering structure. Background technique [0002] Ventilation fan is a type of air-conditioning appliance that is driven by a motor to rotate the fan blades to exchange air between indoors and outdoors, also known as ventilation fans. The innovation and design of high-tech ventilation fans play a role in promoting the development of high-tech industries. [0003] Existing ventilating fans for high-tech industrial ventilation cannot filter and purify the impurities in the inhaled air during ventilation, resulting in a certain degree of impact on the relevant components inside the ventilating fan due to the relatively large impurity particles in the air , and because it cannot purify the inhaled air, the gas will pollute the outside air. Therefore, we propose a ventilation fan with an air filter structure. Contents of the i...
