Embodiment 1

[0030] An air outlet at one end of the air collecting tube (1) is fixedly connected with an air inlet at one end of the fan (2), and the air collecting tube (1) is cylindrical. The air outlet at the other end of the blower fan (2) is fixedly connected with the air inlet tube (13) of the cyclone (3). The fan (2) blows the clean air into the cyclone (3) through the air collector (1), so that the clean air rotates in the cyclone (3), forming a rotating air flow, which is uniform along the inner wall of the cyclone (3). The flow direction rotates and rotates around the axis of the cylindrical body to the outlet end, and the rotating air flow forms a low-pressure core at the outlet end of the air inlet cylinder (5), generating suction force. The air outlet (14) of the swirler (3) is fixedly connected with the air inlet of the exhaust air duct (4), and the exhaust air duct (4) is a tubular gradual expansion shape, and the exhaust air duct (4) The end of the exhaust outlet is placed...

Embodiment 2

[0033]One end of the air collecting tube (1) is fixedly connected with the air inlet at one end of the fan (2), and the air collecting tube (1) is cylindrical. The air outlet at the other end of the blower fan (2) is fixedly connected with the air inlet tube (13) of the cyclone (3). The fan (2) blows the clean air into the cyclone (3) through the air collector (1), so that the clean air rotates in the cyclone (3), forming a rotating air flow, which is uniform along the inner wall of the cyclone (3). The flow direction rotates and rotates around the axis of the cylindrical body to the outlet end, and the rotating air flow forms a low-pressure core at the outlet end of the air inlet cylinder (5), generating suction force. The air outlet tube (14) of the swirler (3) is fixedly connected with the air inlet of the exhaust air tube (4), and the exhaust air tube (4) is a cylindrical gradually expanding shape. A dust collection chamber (9) is arranged at the exhaust outlet end of the...

Embodiment 3

[0036] One end of the air collecting tube (1) is fixedly connected with the air inlet at one end of the fan (2), and the air collecting tube (1) is cylindrical. The air outlet at the other end of the blower fan (2) is fixedly connected with the air inlet tube (13) of the cyclone (3). The fan (2) blows the clean air into the cyclone (3) through the air collector (1), so that the clean air rotates in the cyclone (3), forming a rotating air flow, which is uniform along the inner wall of the cyclone (3).

Abstract

A cyclone-type sucking-exhausting machine features that the clean air is blown by blower into a cyclone chamber, where a cyclone is generated, which rotates along the inner surface of cyclone chamber to generate a central negative region for sucking the dust, garbage, oil soot, and harmful gas or substances into an exhaust barrel and then exhausting them. Its advantages are high efficiency and safety, reasonable structure, low noise and wide application range.

Description

technical field [0001] The invention relates to a swirl device, in particular to a swirl suction and exhaust mechanical device. Background technique [0002] At present, although the existing vacuum cleaners, road sweepers, range hoods, and exhaust ventilation systems for dangerous and harmful gases such as flammable, explosive, and corrosive gases have different uses and structures, their basic structures are all Use the blower to directly blow, suck and exhaust various substances. For example, the basic structure of a vacuum cleaner and a road sweeper is composed of a fan, a dust suction pipe, a dust collection chamber, a dust filter, and a box. When working, the fan draws out the air inside the vacuum cleaner, reducing the air inside the vacuum cleaner and forming a negative pressure. The outside air is sucked into the suction pipe through the suction head, and at the same time, the dust and garbage around the suction head are sucked into the dust collection room throug...
