Provided in embodiments of the present application are a head mechanism and a fan apparatus. The head mechanism includes: a casing, where a primary air inlet and an air outlet are provided on a circumferential side wall of the casing, and an auxiliary air inlet is provided on an axial wall surface of the casing; and a centrifugal volute arranged in the casing, where a centrifugal fan is arranged in the centrifugal volute, and an air duct outlet corresponding to the air outlet and an air duct inlet corresponding to the auxiliary air inlet are provided on the centrifugal volute; and air flowing from the primary air inlet and the auxiliary air inlet flows into the centrifugal volute through the air duct inlet. According to the embodiment of the present application, since the primary air inlet located on the circumferential side wall is provided.

Head mechanism and fan apparatus

Disclosed is a fan. The fan includes a support, a first motor, a first blade, a second motor, a second blade and an electronic control board. The first motor and the second motor are both installed on the support. The first motor is coaxial with the second motor. The first motor has a first rotation shaft and the second motor has a second rotation shaft. The first blade is installed on the first rotation shaft. The second blade is installed on the second rotation shaft. A torsion direction of the first blade is opposite to a torsion direction of the second blade. The electric control board is electrically connected to the first motor and the second motor, and includes a speed ratio adjustment device. The fan can provide a variety of air outlet modes and can quickly adjust between different air outlet modes.

Fan with synchronously switch for rotation directions

A rear guard of a box fan comprises: a body arranged vertically and a waterproof part arranged on the body. The waterproof part is arranged in a position corresponding to a motor in the box fan and the waterproof part comprises a plurality of recessed structures arranged on the body. a plurality of vent holes are arranged on the body for communicating an inner side of the body with an outer side of the body are arranged in the recessed structures. By arranging the vent holes in the recessed structures, the waterproof effect is realized on the premise of ensuring ventilation, the electric leakage and ignition of the motor can be effectively prevented, and the lifetime of the motor of the box fan is extended.

A housing () for a box fan (), the box fan () and an assembly method therefor are provided. The box fan () includes a housing () and a fan blade. The housing () includes two shields () and a frame. The two shields () are arranged opposite to and spaced apart from each other. The frame is arranged between the two shields (). The frame and the two shields () are joined and mounted through their own structures respectively, and at least one of the shields can be attached to or detached from the frame by pushing or pulling. The fan blade is rotatably installed in the housing (). The box fan is easy to assemble and low in cost.

Housing for box fan, box fan and assembly method thereof

Disclosed is a rear grill assembly for a box fan including a rear grill, an electric motor support positioned on the rear grill by a positioning structure, and a frame arranged on the periphery of the rear grill by a snap structure. The frame includes a bottom cover, a top cover, and two side boards connected between the bottom cover and the top cover. The electric motor support is positioned on the rear grill by the positioning structure so that the electric motor support can be mounted easily and firmly. Thus, shortening the time for mounting the motor support, and improving the efficiency for mounting the rear grill assembly. Moreover, since the bottom cover, the top cover and the two side boards are assembled to form a frame, each part can be produced separately, whereby the difficulty in producing the frame is decreased to a certain extent.
