Patent number: 11015617Abstract: 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.Type: GrantFiled: April 23, 2018Date of Patent: May 25, 2021Assignees: GD MIDEA ENVIRONMENT APPLIANCES MFG.

Patent number: 10859099Abstract: A housing (100) for a box fan (1), the box fan (1) and an assembly method therefor are provided. The box fan (1) includes a housing (100) and a fan blade. The housing (100) includes two shields (111, 112) and a frame. The two shields (111, 112) are arranged opposite to and spaced apart from each other. The frame is arranged between the two shields (111, 112). The frame and the two shields (111, 112) 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 (100). The box fan is easy to assemble and low in cost.Type: GrantFiled: December 14, 2015Date of Patent: December 8, 2020Inventors: Runming Guo, Weiliang Liu, Fengxi Yan, Xusheng Zhang, Meihua Deng

Patent number: 10731667Abstract: 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.Type: GrantFiled: November 29, 2016Date of Patent: August 4, 2020Inventors: Runming Guo, Weiliang Liu, Fengxi Yan, Xusheng Zhang, Meihua Deng
