a ventilation device

Abstract

The invention provides a ventilating device, and belongs to the technical field of ventilating. The ventilating device comprises a lower housing, an upper cover and a gas outlet tube, wherein the upper cover covers the upper end of the lower housing; the gas outlet tube communicates with the lower housing; a liquid cabin is arranged on the lower part of the lower housing; an inner concave part is arranged in the middle of the bottom surface of the lower housing; a penetrating hole is formed in the top of the inner concave part; a gas inlet end of the gas outlet tube is rotatably arranged in the inner concave part; a gas outlet end is rotatably arranged on the gas inlet end of a fan; a filter element is arranged in the penetrating hole; a baffle plate is arranged on the upper cover; a gas inlet channel is formed between the upper cover and the baffle plate; a guide blade is arranged in the gas outlet tube; an impeller shaft sleeve is rotatably arranged on the inner concave part; an impeller sleeves the impeller shaft; a driven magnet is arranged on the tubular impeller shaft sleeve; a drive magnet which corresponds to the driven magnet on the impeller shaft sleeve is arranged on the gas outlet tube; and a magnetic fluid bearing is adopted between the gas outlet tube and the inner concave part to perform magnetic fluid rotary sealing. The ventilating device has the advantages of being capable of purifying air and saving energy resource.

Description

technical field [0001] The invention belongs to the technical field of ventilation, and relates to a ventilation device. Background technique [0002] Ventilation devices are used in a wide range of applications, such as buildings, ships and automobiles. Ventilation devices are generally composed of air ducts and fans, and the fans drive air to flow in the air ducts, thereby achieving the purpose of ventilating fixed locations. [0003] The air in the air duct contains kinetic energy, how to use and recover this kinetic energy is a problem that needs to be solved. [0004] In addition, there may be some impurity particles in the air entering the air duct from the outside. After these impurity particles enter the fan, they will cause damage to the blades and inner cavity of the fan and reduce the service life of the fan. Contents of the invention [0005] The object of the present invention is to solve the above-mentioned problems in the prior art, and propose a ventilati...
