Abstract
The utility model discloses an axial flow fan with large suction force. The axial flow fan with the large suction force comprises a fan body composed of a rotating shaft and two or more blades mounted on the rotating shaft. The two side surfaces of each blade are a pressure surface on the air outlet side and a force suction surface on the air inlet side respectively. A round frame coaxial with the rotating shaft is mounted on the periphery of the blades. A circular ring perpendicular to the round frame is mounted on the periphery of the round frame. The axial flow fan with the large suction force further comprises a cylindrical base body located on the periphery of the fan body. The inner circumferential surface of the cylindrical base body is provided with a radial annular groove which extends into the side wall of the cylindrical base body. The periphery of the circular ring extends into the radial annular groove. By the adoption of the structure, the round frame is mounted on the periphery of the blades, the circular ring is mounted on the periphery of the round frame, and the periphery of the circular ring extends into the radial annular groove; as a result, a certain labyrinth seal structure is formed, loss of the air volume is greatly reduced, and energy consumption is lowered.

Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, large suction axial-flow blower that energy loss is little.
In order to solve the problems of the technologies described above, large suction axial-flow blower of the present utility model, comprise rotating shaft and be arranged on two fan main bodies that above blade forms in rotating shaft, the bi-side of every blade are respectively the pressure side of air side and the suction surface of inlet side, the periphery of fan blade is provided with the circular housing with the coaxial setting of rotating shaft, the periphery of circular housing is provided with and the vertically arranged annulus of circular housing, also comprise a tubular matrix that is positioned at fan main body periphery, on the inner peripheral surface of tubular matrix, be provided with the radially annular groove extending in tubular base side walls, the periphery of annulus extend into radially in annular groove.
Described tubular matrix comprises left matrix and right matrix two-part of radially splitting, after fan main body is arranged in left matrix and right matrix by fastening piece by left matrix with right matrix is fixing forms complete entirety.
Described tubular matrix comprises upper matrix and the lower substrate along the circumferential direction split, and fan main body forms complete entirety by upper matrix capping after being arranged in lower substrate.
In the sidewall of described tubular matrix, be provided with two above axial annular grooves of along the circumferential direction arranging, described axial annular groove and radially annular groove connect mutually, are provided with the outer shroud that is positioned at axial annular groove on described annulus.
Described tubular matrix is made up of matrix on polylith and lower substrate, and fan main body is placed in respectively between adjacent upper matrix and lower substrate.
The upper and lower surface of described upper matrix and lower substrate is provided with positioning hole and can be inserted into the locating stud in annular groove.
Between described adjacent upper matrix and lower substrate, be provided with seal ring.
Adopt after above-mentioned structure, the annulus that install the circular housing of installing due to the periphery of fan blade and the periphery of circular housing, the periphery of annulus extend into radially in annular groove, makes thus it form certain labyrinth seal structure, greatly reduce the loss of air quantity, reduced energy consumption.
