Problems solved by technology

[0003] The diversion grille of the existing air circulation fan is installed at the axial air outlet. When the circulation fan is in a non-working state, the dust from the outside easily enters the air duct through the diversion grille, and the impeller downstream of the air duct and Deposition on the fan will affect the service life of the fan and easily cause noise

Embodiment 1

[0054] Such as Figure 1 to Figure 9 As shown, an air guide structure provided in this embodiment includes a frame body 1, which is arranged under the air outlet grille 3, and an air outlet flow channel is formed in the frame body 1; The pieces 2 are rotatably arranged at intervals in the frame body 1; wherein the guide piece 2 has a first state of closing the air outlet channel and a second state of opening the air outlet channel when driven by an external force.

[0055]The air guide structure in this embodiment is used on the circulation fan. A fan is installed at the air inlet at the lower end of the circulation fan to guide the air flow from the outside into the air duct, and flow out to the outside through the air outlet grid in this embodiment. The grill is provided on the housing 6 . The frame body 1 in this embodiment is used as a part of the air duct of the entire circulation fan, and an air outlet flow channel is formed therein.

[0056] The air guide structure in...

Embodiment 2

[0067] Such as Figure 10 As shown, it is a fan provided in this embodiment, specifically a circulation fan, which includes the air guide structure in the above embodiment, and has all its technical advantages, and will not be repeated here.

Abstract

The invention relates to the technical field of fans, in particular to an air guide structure and a fan. The air guide structure comprises a frame body, the frame body is arranged below an air outlet grille, and an air outlet flow channel is formed in the frame body; in the radial direction of the air outlet flow channel, a plurality of flow deflectors are rotatably arranged in the frame body at intervals; and the flow deflector has a first state of closing the air outlet flow channel and a second state of opening the air outlet flow channel under the driving of external force. According to the air guide structure and the fan, the flow deflectors are arranged below the air outlet grille and can rotate in an air outlet duct, when the fan does not work, the flow deflectors rotate, the multiple flow deflectors are spliced, an annular air duct is closed, and therefore dust is prevented from entering the air outlet duct through an air outlet of the air outlet grille, and use of the fan and the like is prevented from being affected.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an air guide structure and a fan. Background technique [0002] The main structure of the air circulation fan includes a drive motor, a turbo fan, a diversion grille and a cylindrical shell. The air circulation fan can let the wind blow out in a spiral shape along a certain direction, and with the stirring of the fan blades, a spiral columnar wind can finally be formed. The wind blown by the air circulation fan has a long distance and good directionality. [0003] The diversion grille of the existing air circulation fan is installed at the axial air outlet. When the circulation fan is in a non-working state, the dust from the outside easily enters the air duct through the diversion grille, and the impeller downstream of the air duct and Deposition on the fan will affect the service life of the fan and easily cause noise. Contents of the invention [0004] Therefore, the technic...
