Axial flow dust extraction device for vehicle

Abstract

The invention belongs to a dust suction device, in particular relates to a vehicle axial flow type dust suction device, which overcomes the defects of the existing centrifugal type dust suction device, improves the filtering efficiency of a cyclone pipe, and meets the requirements of high flow quantity, high pressure head, labor saving and small size. The axial flow type dust suction device comprises a casing (1), an axial flow type impeller (2), a back casing (5), a motor (6) and a motor socket sealing sleeve (7), wherein the casing (1) comprises an inner sleeve (8), a plurality of guide blades (9) and an outer sleeve (10), the guide blades (9) are positioned between the inner sleeve (8) and the outer sleeve (10), and are uniformly distributed in the circumferential direction of the inner sleeve, the inner sleeve (8) is fixedly connected with the outer sleeve (10) through the guide blades (9), the motor (6) is fixed on the back casing (5), the back casing (5) is fixedly connected with one end of the outer sleeve (10), a motor shaft penetrates through the inner sleeve (8) and extends out of the other end of the inner sleeve (8), the extending end of the motor shaft is sleeved with the axial flow type impeller (2), and the axial flow type impeller (2) is fixedly connected with the motor shaft.

Description

technical field [0001] The invention belongs to a dust extraction device, in particular to an axial flow dust extraction device for vehicles. Background technique [0002] The dust extraction device is an important part of the car air filter with a swirl tube, and its function is to extract the sand, dust and other particles that are filtered and separated by the swirl tube from the dust collection chamber of the swirl tube. Thereby ensuring the separation efficiency of the swirl tube. The experimental data shows that the filtration efficiency of the straight-through cyclone tube without dust extraction device is 10% to 20% of that of the cyclone tube with dust extraction device. Therefore, the quality of the dust extraction device directly affects the efficiency and efficiency of the cyclone tube. The service life of the car air filter. [0003] At present, most of the dust extraction devices of vehicle air filters are centrifugal dust extraction devices. Due to the limit...
